Referring more in detail to the drawings:
In the disclosed embodiment of the present invention, the reference numeral 1 designates generally a container cover and safety closure structure for a container 2 having a flowable material therein. The container cover and closure structure 1 includes a cap member 3 integral with or mounted on the container 2 and having a material dispensing aperture 4 in a wall 5 of the cap member 3. A closure member 6 is hingedly mounted on the cap member 3 and is movable between an open position and a position in covering relation with and closing the material dispensing aperture 4. A latch member 7, closure member 6 and cap member 3 have cooperating portions 8 and 9 respectively engageable one with the other for retaining the closure member 6 in covering relation with and closing the material dispensing aperture 4. The cover and closure structure 1 includes a resilient member or members 10 for urging the cooperating portions 8 and 9 on the latch member 7 and the cap member 3 into retaining engagement. To move the closure member 3 to the open position, it is first necessary to move at least a portion of the closure member 6 toward the cap member 3 against resistance of the resilient member or members 10 and second to separate the cooperating portions 8 and 9 and then move the closure member 6 to the open position.
The container 2 may be any suitable size and shape for retaining therein material to be dispensed. The illustrated container 2 has a neck portion 11 with a lip 12 at an upper end of the neck portion 11 thereby defining a downwardly facing shoulder. The container 2 is formed of flexible and resilient material so that the cap member 3 may be mounted on the neck portion 11 of the container 2.
The cap member 1 has a side wall 14 depending from the top wall 5 and the side wall 14 is adapted to surround the neck portion 11 of the container 2. The side wall 14 has means engageable with the container wall for retaining the cap member 3 on the container 2. In the illustrated method of mounting the cap member 3 on the neck portion 11 of the container 2, the side wall 14 has an inwardly extending rib for bead 15 adjacent a lower edge of an interior surface of the cap member side wall 14. The bead or rib 15 and the downwardly facing shoulder defined by the lip 12 on the neck portion 11 of the container 2 cooperate to retain the cap member 3 on the container neck portion 11.
An exterior surface of the cap member side wall 14 has a guide recess or way 16 therein which extends between a lower edge of the side wall 14 and the cap member top wall 5. The latch 7 is received in the guide way 16 in the cap member side wall 14. A downwardly inclined shoulder 17 is formed in the guide way 16 in the cap member side wall 14 and the downwardly inclined shoulder 17 is positioned adjacent the cap member top wall 5. The shoulder 17 terminates in a lower edge spaced from the outwardly facing surface of the walls defining the guide way 16. In the illustrated structure, an upwardly and inwardly inclined surface extends from the lower edge of the shoulder 17 and toward the cap member top wall 5. The cap member top wall 5 also has a guide way or recess 18 therein and extending between opposite side edges of the top wall 5. The guide way 18 in the top wall 5 and the guide way 16 in the side wall 14 intersect at one of the opposite side edges of the cap member top wall 5.
The material dispensing aperture 4 is formed in the cap member top wall 5 and in the illustrated embodiment, the material dispensing aperture 4 is defined by a tubular portion 19 extending upwardly from the top wall 5 and having a bore 20 therethrough. The tubular portion 19 is positioned within the guide way 18.
The closure member 6 has one end portion thereof hingedly mounted on the cap member top wall 5 by a hinge portion 21 positioned in opposed relation to the guide way 16 in the cap member side wall 14. The closure member 6 has a wall portion 22 adapted to be in covering relation with a center portion 23 of the top wall 5 within the guide way 18. Peripheral edge flanges 24 extend substantially perpendicular or normal to the wall portion 22 and are engageable with the center portion 23 of the cap member top wall 5 and thereby provide support for the closure member wall portion 22. The edge flanges 24 are formed on the one end portion of the closure member 6 and terminate within an intermediate portion of the closure member wall portion 22 so that the one end portion having the edge flanges 24 thereon is in supported engagement with or on the center portion 23 of the cap member top wall 5. The other end portion of the closure member wall portion 22 between the ends of the edge flanges 24 and the latch 7 is flexible and may be moved toward the center portion 23 of the cap member top wall 5.
The closure member 6 has means thereon for closing the material dispensing aperture 4 when the closure member 6 is in covering relation with the cap member top wall 5 and the material dispensing aperture 4. In the illustrated embodiment, a sleeve portion 25 extends from the intermediate portion of the wall portion 22 of the closure member 6 and surrounds the tubular portion 19 when the closure member 6 is in covering relation with the material dispensing aperture 4. The tubular portion 19 defining the material dispensing aperture 4 and the sleeve portion 25 are spaced from the guide way 16 in the cap member side wall 14 and the latch 7 respectively.
A pin or projection 26 extends from an intermediate portion of the closure member wall portion 22 and is positioned within and surrounded by the sleeve portion 25. The pin or projection 27 is frictionally received within the bore 20 of the tubular 27 is frictionally received within the bore 20 of the tubular portion 19 thereby providing a liquid tight seal or closure for the material dispensing aperture 4 when the closure member 6 is in covering relation with the material dispensing aperture 4.
The latch 7 is formed as a portion of the closure member 6 and extends from the other end portion of the closure member 6 and is substantially perpendicular or normal to the wall portion 22 of the closure member 6. The latch portion 7 is received in the guide way 16 in the cap member side wall 14.
The latch 7 has a projection or rib defining an upwardly inclined shoulder 27 on a latch surface facing the cap member side wall 14. The upwardly inclined shoulder 27 on the latch 7 is engageable with the downwardly inclined shoulder 17 within the guide way 16 in the cap member side wall 14. The downwardly inclined shoulder 17 and the upwardly inclined shoulder 27 on the cap member side wall 14 and the latch 7 respectively thereby define cooperating means on the cap member side wall 14 and the latch 7 which are engageable one with the other for retaining the closure member 6 in covering relation with the material dispensing aperture 4.
The cover and closure structure 1 includes one or more resilient members 10 on one of the closure member 6 and the cap member 3 for urging the cooperating means defined by the shoulders 17 and 27 on the cap member side wall 14 and the latch 7 respectively into retaining engagement one with the other. The one end portion of the closure member wall portion 22 and the latch 7 thereon is movable towards the cap member top wall 5 against resistance of the resilient member or members 10 to permit separation of the shoulders 17 and 27 on the cap member side wall 14 and the latch 7 respectively.
In the illustrated embodiment, the closure member 6 has two resilient members 10 on the wall portion 22 and positioned on the opposite sides of the latch 7 at the other end portion of the closure member wall portion 22 and the resilient member 10 are integral with the closure member 6.
The cap member 3, closure member 6, latch 7, and resilient member 10 are formed as a one-piece, molded structure of a suitable flexible and resilient plastic.
In using a cover and closure structure 1 as illustrated and described, the container 2 is filled with the desired material to be dispensed, such as a liquid soap, body or hand lotion, shampoo, hair creme or conditioner, and the like. The cap member 3 is moved downwardly over the neck portion 11 of the container 2 until the bead or rib 15 on the cap member side wall 14 moves over and under the lip 12 on the neck portion 11 of the container 2. The closure member 6 is moved to a position overlying or in covering relation with the cap member top wall 5 and the material dispensing aperture 4 so that the sleeve portion 26 on the closure member wall portion 22 surrounds the tubular portion 19 extending upwardly from the cap member top wall 5 and the pin or projection 26 is received in the bore 20 of the tubular projection or portion 19. The latch 7 is received in the guide way 16 in the cap member side wall 14. The other end portion of the closure member wall portion 22 adjacent the latch 7 is depressed to allow the shoulders 17 and 27 to engage. Release of the other end portion of the closure member wall portion 22 effects seating engagement of the shoulder 27 on the latch 7 with the shoulder 17 on the cap member side wall 14. When it is desired to dispense material through the material dispensing aperture 4, the other end portion of the closure member wall portion 22 adjacent the latch 7 is depressed or moved toward the cap member top wall 5 and the free end of the latch 7 is moved out of the guide way 16 in the cap member side wall 14 and then outwardly from the cap member side wall 14 so that the closure member 6 may be moved to the open position.
FIGS. 5 to 8 inclusive illustrate a first modified form of a container cover and closure structure 31 particularly adapted for use in dispensing a granular material, such as salt, sugar, pepper, spices, tablets, pills, and the like. In the form illustrated, a container 32 has an upper portion 33 with an outwardly extending lip 34 on the side wall of the container 32 thereby defining a downwardly facing shoulder. The container 32 is formed of flexible and resilient material so that a cap member 35 may be mounted on the upper end portion 33 of the container 32.
The illustrated cap member 35 has a side wall 36 depending from a top wall 37 and the cap member 35 is adapted to surround the upper end portion 33 of the container 32. The cap member side wall 36 has means engageable with the container wall adjacent the upper end portion 33 for retaining the cap member 35 on the container 32. In the illustrated method of mounting the cap member 35 on the container 32, the cap member side wall 36 has a recess 38 therein and positioned adjacent a lower edge of an interior surface of the cap member side wall 36. The recess 38 is adapted to receive therein the lip 34 on the exterior surface of the container wall adjacent the upper end portion 33 of the container 32.
The illustrated cap member side wall 36 has an inner wall portion 39 and an outer wall portion 40. The outer wall portion 40 extends around the entire circumference of the cap member 35 and has the recess 38 therein. The inner wall portion 39 may extend around the entire circumference of the interior surface of the container side wall, however, it is preferred that the inner wall portion 39 extend at least around a major portion of the circumference of the cap member side wall 36.
The exterior surface of the cap member outer wall portion 40 has a guide recess or way 41 therein. A latch member 42 extends from a modified closure member 43 which is hingedly mounted on the top wall 37 of the cap member 35. The latch member 43 is received in the guide recess or way 41 in the cap member side wall 36. A guide recess or way 44 is formed in the cap member top wall 37 and extends between the inner and outer wall portions 39 and 40 of the side wall 36. The recess 44 in the cap member top wall 37 intersects the guide recess 41 in the side wall 36 of the cap member 35.
The material dispensing aperture 45 is formed in the cap member top wall 37 and is preferably large enough to permit a spoon or the like to be moved into the container 32 and removed with a desired quantity of material from the container 32. The material dispensing aperture 45 has one surface thereof flush with the inwardly facing surface of the inner wall portion 39. A rib or bead 46 extends inwardly from an inwardly facing surface of the inner wall portion 39 and provides a support for the closure member 43.
In the illustrated structure, a portion of the cap member top wall 37 is hingedly connected to the remaining portion of the cap member top wall 37 thereby defining the closure member 43. The portion of the cap member top wall defining the closure member 43 has a peripheral edge with a flange 47 extending therefrom and engageable with the inner wall portion 39 of the cap member side wall 36. The flange 47 extending from the closure member 43 engages the rib or bead 46 extending from the inner wall portion 39 of the cap member side wall 36 and is supported thereon.
The illustrated latch 42 has a first portion 48 extending from the closure member 43 and received in the guide way or recess 44 in the top wall 37 of the cap member 35. The latch 42 has a second portion 49 extending substantially perpendicular or normal to the first latch portion 48 and received in the guide way 41 in the cap member side wall 36.
The cap member side wall 36 and the latch member second portion 49 have cooperating means engageable one with the other for retaining the closure member 43 in covering relation with and closing the material dispensing aperture 45. In the illustrated structure, the side wall 36 of the cap member 35 has a downwardly inclined shoulder 50 formed within the guide way 41 in the cap member side wall 36. The illustrated shoulder 50 is formed in a lower edge of the outer wall portion 40 of the side wall 36. The latch member second portion 49 has a projection or rib defining an upwardly inclined shoulder 51 engageable with the downwardly inclined shoulder 50 on the outer wall portion 40 of the cap member side wall 36 so that resilient means 52, as later described, urge the latch member shoulder 51 into engagement with the shoulder 50 on the cap member side wall 36.
The resilient means 52 are illustrated as a leaf formed integral with and extending from the inner wall portion 39. The resilient leaf 52 has a length at least equal to the width of the guide ways 41 and 44 and the leaf 52 is positioned between the ribs or beads 46. The resilient leaf 52 engages the closure member 43 when the closure member 43 is in the closed position.
It is desirable to provide means on the closure member 43 engaged by the resilient leaf 52 for stiffening the closure member 43 and reducing the width or unsupported dimension of the resilient leaf 52 so that the leaf 52 is sufficiently stiff to hold the shoulders 50 and 51 in cooperation engagement. The illustrated closure member 43 has a pair of laterally spaced ribs 53 and 54 on the interior surface thereof and extending between the second latch portion 49 and the hinge connection of the closure member 43 to the remaining portion of the closure member top wall 37. The ribs 53 and 54 are substantially normal or perpendicular to the second latch portion 43.
Use of the container cover and closure structure 31 illustrated in FIGS. 5 to 8 inclusive is similar in principle to the use of the cover and closure structure 1 illustrated in FIGS. 1 to 4 inclusive. To open the cover and closure structure 31, the closure member 43 is first moved toward the container 32 until the ribs 53 and 54 engage the surface defining the guide way 44 in the cap member top wall 37 so that the second latch portion 49 may be moved outwardly from the cap member side wall 36 and the closure member 43 then moved to an open position.
FIGS. 9 to 12 inclusive illustrate a second modified form of a container cover and closure structure 61 also particularly adapted for use in dispensing of granular material, such as salt, sugar, pepper, spices, pills, tablets, and the like.
The cover and closure structure 61 includes a cap member 62 having a side wall 63 and a top wall 64. The cap member side wall 63 is suitably mounted on a container.
