Abstract
An improved receptacle includes a cover which is connected with a rear panel of the receptacle along a fold line to enable the cover to be pivoted between open and closed positions. Prior to opening of the receptacle, a front section of the cover is firmly held in juxtaposition with a front panel of the receptacle so that the cover cannot be partially raised under the influence of forces applied to the receptacle during handling. When the cover is firmly pulled open, a rip out section is torn from the front panel to form an opening which extends downwardly from an upper edge of the front panel. The rip out section is secured to the inside of the front section of the cover by adhesive. When the cover is closed, indentations formed in the rip out section are engaged by projections formed in the opening in the front panel to hold the cover closed. In certain embodiments, a pair of retaining surfaces are connected with the inside of the cover and are engaged by retaining tabs which are pivotally connected with an upper edge of the front panel to further hold the cover closed.

Description
Background of the Invention
This invention relates generally to a receptacle and more specifically to a receptacle having a cover which is pivotal between open and closed positions.
There are many known receptacles having pivotally mounted covers or flip tops. One of these known receptacles is disclosed in U.S. Pat. No. 4,127,229 and includes a cover having a front section which is secured by adhesive to an upper portion of a front panel of the receptacle. Upon lifting of the cover, the front section of the cover separates the upper portion of the front panel from a lower portion of the front panel to expose the contents of the receptacle.
Another receptacle having a pivotally mounted cover is disclosed in U.S. Pat. No. 3,893,614. The receptacle disclosed in this patent includes a sealing tab which is releasably attached to an upper edge of a front panel of the receptacle. The sealing tab is secured by adhesive to an inner surface of the front panel. A pair of locking or retaining tabs are also connected with the upper edge of the front panel along fold lines. The retaining tabs cooperate with flaps on the inside of the cover to hold the cover closed after the receptacle has initially been opened.
Summary of the Present Invention
A receptacle constructed in accordance with the present invention includes a cover which is pivotally connected with a back panel for movement between open and closed positions. A front panel of the receptacle has a rip or pull out section which is defined by a score line. Adhesive connects the rip or pull out section in flat juxtaposition with an inner side of a front section of the cover to hold the front section of the cover in flat abutting engagement with the front panel prior to opening of the receptacle. When the receptacle is initially opened, the adhesive causes the rip out section to tear away from the front panel of the receptacle to form an opening in the front panel and expose the contents of the receptacle.
Once the receptacle has been opened and the cover moved back to the closed position, a pair of locking or retaining tabs on the upper edge portion of the front panel engage surfaces on the inside of the front section of the cover to hold the cover in the closed position. In addition, the cover is held in the closed position by meshing engagement between indentations and projections formed by removing the rip out section from the front panel of the receptacle.
Accordingly, it is an object of this invention to provide a new and improved receptacle having a pivotally mounted cover which is secured to a rip out section formed in a front panel of the receptacle to firmly hold the cover in place before initial opening of the receptacle.
Another object of this invention is to provide a new and improved receptacle as set forth in the preceding object and wherein retaining tabs cooperate with the cover to hold it closed after it has been intially opened and then returned to the closed position.

Description of Specific Preferred Embodiments of the Invention
A receptacle or box 20 (FIG. 1) includes a rectangular body 22 which is closed by a cover or flip top 24. The body 22 includes flat parallel front and rear panels 26 and 28 (see FIGS. 1 and 2) which are interconnected by a pair of flat parallel side panels 30 and 32. A flat bottom panel 34 (FIG. 1) extends perpendicular to the front and rear panels 26 and 28 and the side panels 30 and 32. The bottom panel 34 interconnects the front, side and rear panels to form a rectangular paperboard receptacle for receiving articles such as individually wrapped packages of food.
The cover or flip top 24 is movable between a closed position (FIGS. 1 and 2) blocking access to the interior of the receptacle 20 and an open position (FIG. 3) in which articles within the receptacle are accessible. To enable the cover 24 to be repeatedly moved between the open and closed positions, the cover is pivotally or hingedly connected with an upper edge of the rear panel 28 along a fold or hinge line 38 (FIGS. 2 and 3). The fold line 38 extends parallel to the bottom panel 34 and interconnects the back panel 28 and flat upper or top section 40 of the cover. The top section 40 of the cover 24 extends parallel to the bottom panel 34 when the cover is in the closed position of FIGS. 1 and 2.
In addition to the top section 40, the cover 24 has a flat front section 44 which extends perpendicular to the top section 40. When the cover 24 is in the closed position of FIGS. 1 and 2, the front section 44 is disposed in juxtaposition with the front panel 26. The cover 44 also has a pair of side sections 46 and 48 (see FIG. 3) which extend perpendicular to the front section 44. The side sections 46 and 48 are disposed in juxtaposition with the side panels 30 and 32 when the cover 24 is in the closed position of FIG. 1.
In accordance with a feature of the present invention, the cover 24 is firmly held in the closed position until the receptacle 20 is intentionally opened. This prevents the cover 24 from being inadvertently dislodged to a partially raised position under the influence of forces commonly encountered during normal handling of the receptacle 20. Thus, when the cover 24 is in the closed position of FIGS. 1 and 2, the entire front section 44 of the cover is firmly anchored in a parallel relationship with the front panel 26 by a layer 52 (FIG. 2) of adhesive. The layer 52 of adhesive extends downwardly to a location immediately adjacent to a lower edge or lip 54 of the front portion 44 of the cover 24.
The application to the receptacle of the forces encountered in normal handling of a package urge the lip 54 of the cover in a direction tending to move the front section 44 of the cover upwardly and/or outwardly away front the front panel 26. However, the layer 52 of adhesive firmly holds the cover in place. This prevents the cover 24 from being dislodged to a cocked or slightly open position until the somewhat larger force required to initially move the cover 24 from the closed position to the open position is applied to the cover.
In order to provide for opening of the receptacle 20, a force of a predetermined magnitude must applied to the cover 24. This results in an opening of the receptacle 20 with a controlled tearing away of a predetermined portion of the front panel 26. To this end, front panel 26 is provided with a rip or pull out section 60 (see FIGS. 2 and 3) which is defined by a line of weakness or score line 62 (FIG. 2) in the front panel 26.
The rip out section 60 is integrally formed with a similarly shaped base section 64 (FIG. 2). The rip out section 60 is connected with the base section 64 along a fold line 65. An outer major side surface 66 of the base section 64 is connected with an inner major side surface of the front section 44 by the layer 52 of adhesive. Similarly, an inner major side surface 68 (FIG. 2) of the base section 64 is connected with an outer major side surface 70 of the rip out section 60 by a layer 72 of adhesive.
The adhesive layers 52 and 72 secure the rip out section 60 to the cover 24 so that upon pulling outwardly of the cover 24 from the closed position shown in FIG. 2 to the open position shown in FIG. 3, the front panel 26 tears along the score line 62. The score line 62 has a generally U-shaped configuration with a pair of side sections 76 and 78 (see FIG. 3) which extend downwardly from an upper edge 80 of the front panel 26 to a bight or cross section 82 which extends parallel to the bottom panel 34.
To provide a line of weakness in the front panel 26, the score line 62 is formed by short cuts which extend through the cardboard panel 26. These short cuts are interspersed with uncut sections of the front panel 26. This enables the rip out section 60 to be torn from the front panel 26 in a controlled manner so that the section will have the configuration shown in FIG. 3.
In accordance with another feature of the present invention, upon movement of the cover from the closed position of FIG. 2 to the open position of FIG. 3, an opening 86 is formed in the front panel 26 to at least partially expose the contents of the receptacle 20. Thus, the opening 86 extends downwardly from the upper edge 80 of the front panel 26 toward the bottom panel 34 and exposes a portion of the contents of the package which was previously behind the front section 44 of the cover 24. Of course, the opening 86 is formed when the rip out section 60 is torn from the front panel 26 during opening of the cover 24.
After the receptacle 20 has been opened, it is contemplated that only a portion of the contents of the receptacle may be removed and the cover returned to the closed position of FIG. 2 in order to protect the remaining contents of the receptacle. In accordance with still another feature of the present invention, the cover 24 is firmly held closed after the receptacle 20 has been initially opened. This results in the cover being held in place to protect the remaining contents of the receptacle.
When the cover 24 is moved from the open position of FIG. 3 back to the closed position of FIG. 2, projections and/or indentations formed along the score line 62 on the front panel 26 and rip out section 60 intermesh to hold the cover in the closed position. Thus, projections 90 and 92 (FIG. 3) along the side 76 of the opening 86 and projections 94 and 96 along the side 78 of the opening engage recesses 98 and 100 along one side of the rip out section 60 and recesses 102 and 104 along the opposite side of the rip out section. The engagement of the projections 90-96 with the recesses 98-104 releasably holds the cover 24 in the closed position shown in FIG. 2 when the receptacle 20 is closed after it has been initially opened.
A pair of locking or retaining tabs 108 and 110 along opposite sides of the opening 86 cooperate with the cover 24 to further hold the cover in the closed position. Thus, the retaining tab 108 has a lower edge or minor side surface 114 which engages a stop edge or minor side surface 116 on a locking flange 118 (FIG. 3) when the cover 24 is closed. The locking flange 118 is fixedly mounted on the inner side surface of the front section 44 of the cover by the adhesive layer 52.
Similarly, the retaining tab 110 has a lower edge or minor side surface 122 which engages a stop edge or minor side surface 124 on a locking flange 126 (FIG. 3) when the cover 24 is closed. The locking flange 126 is fixedly mounted on the inner side surface of the front section 44 of the cover by the adhesive layer 52.
The two locking flanges 118 and 126 are integrally formed with the base 64 and project outwardly from opposite sides of the base 64. The stop surfaces 116 and 124 on the flanges 118 and 126 extend parallel to the edge 54 of the cover 24. Similarly, the stop surfaces 114 and 122 on the tabs 108 and 110 extend parallel to the upper edge 80 of the front panel 26. Of course, the stop surfaces 116, 124, 114 and 122 could be skewed relative to the upper edge 80 of the front panel 26 and/or the lower edge 54 of the cover 24 if desired.
When the cover 24 is pivoted about the fold line 38 from the open position of FIG. 3 to the closed position of FIG. 2, the locking tabs 108 and 110 are pivoted inwardly about fold lines which connect them with the upper edge 80 of the front panel 26. As the cover 24 moves to the fully closed position shown in FIG. 2, the natural resilience of the locking tabs causes them to pivot outwardly about the fold lines at the upper edge of the front panel 26. This results in the top surfaces 114 and 122 (FIG. 3) moving into alignment with the surfaces 116 and 124 on the flanges 118 and 126. Abutting engagement between the stop surfaces 114 and 122 on the tabs and the stop surfaces 116 and 124 on the flanges holds the cover in the closed position shown in FIG. 2. However, when a firm force is applied to the cover urging it toward the open position of FIG. 3, the locking flanges 118 and 126 tend to move outwardly away from the front panel 26 and the tabs 108 and 110 become disengaged from the locking flanges to release the cover for movement to the open position of FIG. 3.
When the cover 24 is initially opended, the front panel 26 is ripped along the score line 62 to separate the rip out section 60 from the front panel. When the cover 24 is return to the closed position of FIG. 2, it is held in place by two separate locking or retaining devices. Thus, the cover is held closed by engagement of the projections 90, 92, 94 and 96 with the recesses 98, 100, 102 and 104. The cover is also held closed by engagement of the locking tabs 108 and 110 with the flanges 118 and 126 on the inside of the cover.
The receptacle 20 is formed from a flat paperboard or cardboard blank 132 (see FIG. 4) having crease or fold lines separating the various panels. Thus, the blank 132 has a crease or fold line 134 which extends parallel to the edge 54 of the cover section 44 to separate the cover section from the top section 40 of the cover. Similarly, the fold line 38 extends parallel to the edge 54 and separates the top section 40 of the cover from the back panel 28. A pair of fold lines 136 and 138 (FIG. 4) extend parallel to the fold line 38 and separate the bottom panel 34 from the back panel 28 and front panel 26.
The side panels 30 and 32 of the receptacle 20 are formed by overlapping flaps. Thus, the side panel 30 includes an inner flap 142 (FIG. 4) which is separated from the rear panel 28 by fold line 144 and a flap 146 which is separated from the front panel 26 by a fold line 148 which is a continuation of the fold line 144. The fold lines 144 and 148 extend perpendicular to the fold line 38. The opposite side panel 32 (see FIG. 3) is formed by a flap 152 (FIG. 4) which is separated from the rear panel 28 by a fold line 154 and a flap 156 which is separated from the front panel 26 by a fold line 158. The fold line 158 is a continuation of the fold line 154 and extends parallel to the fold lines 144 and 148.
To allow the receptacle 20 to be filled from either side rather than the top, the adhesive layers 72 and 52 are connected between the base 64 and the front panel 26 and front section 44 of the cover in the manner shown in FIG. 2. This results in the formation of a tubular structure 164 (see FIGS. 5 and 6) which corresponds to the receptacle 22 with the two side panels 30 and 32 open. The resulting tubular structure (see FIG. 6) has a rectangular opening 166 which extends completely through the structure. It should be noted that the cover 24 is, with the exception of the opposite sides, almost fully formed at this time. However, the tubular structure is open on opposite sides so that articles can be inserted into the tubular structure 164 from either side.
Once the tubular structure 164 has been filled, the inner flaps 142 and 152 (see FIG. 4) are folded in to block the openings on opposite sides of the tubular structure 164. A pair of bottom flaps 170 and 172 are then folded in along fold lines 174 and 176. The outer side flaps 146 and 156 are then folded inwardly into abutting engagement with the inner side flaps 142 and 152 and with the bottom flaps 170 and 172. This results in the bottom flaps being sandwiched between inner side flaps 142 and 152 and the outer side flaps 146 and 156. Suitable adhesive is provided between the side flaps 142 and 146 and 152 and 156 to hold the side flaps in juxtaposition with each other. If desired, one pair of side flaps 142, 146 or 152, 156 could be closed before filling of the tubular structure 164.
Once the side panels 30 and 32 have been formed, the construction of the cover 24 is completed. This is done by folding the top flaps 180 and 182 (FIG. 4) inwardly along fold lines 184 and 186 and folding front flaps 188 and 190 inwardly about fold lines 192 and 194. The top flaps 180 and 182 and front flaps 188 and 190 are held in juxtaposition with each other by suitable adhesive between the flaps to complete the construction of the receptacle 20.
In the embodiment of the invention illustrated in FIGS. 1-6, the rip out section 60 is connected with the front section 44 of the cover by a base 64. The base 64 has outwardly extending locking flanges 118 and 126 which are engaged by the tabs 108 and 110 to hold the cover 24 in the closed position after initial opening of the receptacle 20. In the embodiment of the invention shown in FIGS. 7 and 8, the rip out section is mounted directly on the inner side surface of the front section of the cover and locking tabs engage retaining sections which are formed separately from the rip out section. Since the embodiment of the invention shown in FIGS. 7 and 8 is generally similar to the embodiment of the invention shown in FIGS. 1-6, similar numerals will be utilized to designate similar components, the suffix letter "a" being associated with the embodiment of the invention shown in FIGS. 7 and 8 to avoid confusion.
A receptacle 20a (FIG. 7) has rectangular main section 22a and a cover or flip top 24a. A front panel 26a extends parallel to a back panel 28a. A bottom panel (not shown) extends between the front and back panels 26a and 28a and a pair of side panels 30a and 32a. The cover 24a is pivotally connected with the back panel 28a along a fold line 38a.
When the cover 24a is initially moved from a closed or sealed position to the open position of FIG. 7, a rip out section 60a is removed from the front panel 26a. This is accomplished by tearing the front panel 26a along a line of weakness or score line 62a to form an opening 86a which extends downwardly from an upper edge 80a of the front panel 26a. The rip out section 60a is secured directly to a front section 44a of the cover 24a by a suitable adhesive.
When the cover 24a is moved back to the closed position, projections 90a, 92a, 94a, and 96a formed in the front panel 26a along the score line 62a engage recesses 98a, 100a, 102a and 104a formed in the rip out section 60a. The meshing engagement between the projections 90a, 92a, 94a and 96a and the recesses 98a, 100a, 102a and 104a hold the cover in the closed position.
Locking or retaining tabs 108a and 110a are formed along the upper edge 80a of the front panel 26a to further hold the cover 24a closed. The retaining tabs 108a and 110a have minor side or stop surfaces 114a and 122a which cooperate with minor side or stop surfaces 116a and 124a disposed on the inner side of the front section 44a of the cover 24a. In accordance with a feature of this embodiment of the invention, the stop or retaining surfaces 116a and 124a are disposed on flaps 200 and 202 which are integrally formed with the side flaps 188a and 190a which are connected with the top section 40a along fold lines 206 and 208.
When the cover 24a is in the closed position shown in FIG. 8, the surface 114a on the locking tab 108a engages the surface 116a on the flap 200. Similarly, the surface 122a on the locking tab 110a engages the surface 124a on the flap 202 when the cover 24a is closed. Abutting engagement of the retaining tabs 108a and 110a with the flaps 200 and 202 holds the cover 24a in the closed position. When a force is applied to the cover 24a lifting the front section 44a upwardly and outwardly to pivot the cover about the fold line 38a, the locking tabs 108a and 110a are disengage from the flaps 200 and 202 and the cover moves to the open position shown in FIG. 7.
In the embodiment of the invention shown in FIG. 9, the function of the locking tabs 108, 108a and 110, 110a of the embodiments shown in FIGS. 1-8 is performed by a portion of the front panel. Since the embodiment of the invention shown in FIGS. 9 and 10 is generally similar to the embodiments of the invention shown in FIGS. 1-8, similar numerals will be utilized to designate similar components, the suffix letter "b" be associated with the embodiment of FIGS. 9 and 10 in order to avoid confusion.
A receptacle 20b (FIG. 9) has a rectangular main body section 22b to which a cover 24b is pivotally connected to a rear panel 28b along a fold line 38b. Upon initial opening of the receptacle 20b, a rip out section 60b is removed from a front panel 26b along a score line 62b. The rip out section 60b is fixedly connected with an inner side surface of a front section 44b of the cover 24b by a suitable adhesive. However, it should be noted that flaps 200b and 202b underlie a portion of the rip out section 60b.
In accordance with a feature of this embodiment of the invention, the opening 86b formed by removing the rip out section 60b is provided with a pair of inwardly projecting tabs or flanges 220 and 222 which cooperate with the rip out section 60b to hold the cover 24b closed. Thus, after the cover 24b has been moved from the open position of FIG. 9 to the closed position of FIG. 10 the flanges 220 and 222 abut the rip out section 60b. The tabs 220 and 222 (FIG. 9) have downwardly facing minor side or retaining surfaces 226 and 228 which engage minor side or retaining surfaces 230 and 232 formed on the rip out section 60b to hold the cover in the closed position (see FIG. 10). Thus, the function of the locking tabs 108 and 110 of the embodiment of invention shown in FIG. 3 is performed by the tabs or flanges 220 and 222 which are defined by the score line 62b and are formed when the rip out section 60b is removed from the front panel 26b.
When the cover 24b is returned to the closed position, it is held closed under the combined influence of the locking tabs 220 and 222 and of meshing engagement between projections formed in the front panel 26b at the opening 86b and recesses in the rip out section 60b. Thus, the front panel 26b, has projections 90b, 92b, 94b and 96b which cooperate with recesses 98b, 100b, 102b and 104b to retain the cover 24b in the closed position.
Although specific preferred embodiments of the invention have been illustrated in FIGS. 1-10, it should be understood that a receptacle constructed in accordance with the present invention could have a somewhat different constructuion if desired. For example, the locking tabs 220 and 222 of the embodiment of the invention shown in FIG. 9 could extend completely across the upper portion of the openings 86b. In addition, if desired, the rip out sections 60a and 60b (FIGS. 7 and 9) could be mounted on the front section 44a or 44b of a cover with a base similar to the base 64 of FIG. 2. In addition, the overall configuration of the receptacle could be changed from the elongaged rectangular configuration illustrated herein.
In view of the foregoing description, it is apparent that a receptacle 20 constructed in accordance with the present invention includes a cover 24 which is pivotally connected with a back panel 28 for movement between open and closed positions. The front panel 26 has a rip or pull out section 60 which is defined by a score line 62. Adhesive 52 connects the rip or pull out section 60 in flat juxtaposition with an inner side of the front section 44 of the cover 24 to hold the front section of the cover in flat abutting engagement with the front panel 26 prior to opening of the receptacle. When the receptacle is initially opened, the adhesive causes the rip out section 60 to tear away from the front panel 26 of the receptacle to form an opening 86 in the front panel and expose the contents of the receptacle.
Once the receptacle has been opened and the cover 24 moved back to the closed position, a pair of locking or retaining tabs 108 and 110 on the upper edge portion 80 of the front panel 26 engage surfaces 116 and 124 on the inside of the front section 44 of the cover 24 to hold the cover in the closed position. In addition, the cover is held in the closed position by meshing engagement between indentations 98, 100, 102 and 104 and projections 90, 92, 94 and 96 formed by removing the rip out section 60 from the front panel 26 of the receptacle.
