Description
BACKGROUND OF THE INVENTION
Sealed envelopes have been used for preserving identification cards, drivers licenses and the like. In a typical lamination process, the information to be preserved is sandwiched between two transparent plastic layers which are secured around the periphery. In this way the outer plastic laminate layers protect the insert.
The prior art such as Wilburger U.S. Pat. No. 1,446,232, Nystrom U.S. Pat. No. 1,683,479, Huni U.S. Pat. No. 3,727,829, and Sengewald U.S. Pat. No. 4,015,771 provided perforations for insert into pins for ring binders or the like.
In particular, Huni U.S. Pat. No. 3,727,829 and Roop U.S. Pat. No. 3,079,066 provide hinged overlying flaps with openings therein.
Farmer U.S. Pat. No. 2,093,977 also shows the idea of providing a flap laminate which folds backward from the hinge to provide a handle or support means for the receptacle. In the Huni and Roop patents, the flap is formed from the rear sheet rather than from the front sheet. Lefebvre U.S. Pat. No. 2,833,401 provides a sealed flap. Geimer U.S. Pat. No. 1,947,934 provides a sealed flap with perforations therein.
The need has existed for a sealed transparent envelope which can be supported on a hook or the like for display purposes in stores and which also may be positioned in a ringed notebook binder.
OBJECTS AND SUMMARY OF THE INVENTION
It is a primary object of this invention to provide a laminated transparent sealed envelope which is provided with means for hanging on a hook or board or the like, as well as means for positioning in a multi-ringed notebook binder.
Yet another object of this invention is to provide means in the sealed envelope which will permit easy breaking of the seal in order to afford ready access to the material therein.
A further object of this invention is to provide an envelope with a flap having a second flap sealed therein with means for readily breaking the seal of the second flap to enable the second flap to be positioned on a hook or the like without breaking the seal of the first flap.
Yet a further object of this invention is to provide an envelope which is inexpensive and easily manufactured.
A further object of this invention is to provide a single hinge means for both the first and second flaps.
Yet a further object of this invention is to provide a flexible transparent envelope having opening means at the top thereof to provide ease in access to the material therein which can be readily reclosed once the material has been removed.
In summary, this invention pertains to a transparent plastic envelope having at the top a sealed main flap with a second flap positioned therein and with means for breaking the seal on both the first and second flaps to provide a hanger as well as means for inserting the envelope into a multi-ringed notebook binder.

DESCRIPTION OF FIGS. 1 through 5
In the preferred form of the invention, the envelope E is made from plastic laminated sheet material bonded by heat. As best shown in FIG. 3, the envelope E comprises an upper laminate sheet 2 and a lower laminate sheet 4. The sheets are bonded at 6.
The entire periphery of the envelope E is provided with a heat seal 8. This heat seal 8 laminates the upper and lower sheets 2 and 4 together.
At the top of the envelope E is a first flap 10 The flap 10 includes a hinge 12. The hinge 12 is formed in the upper laminate sheet 2 prior to lamination to the lower laminate sheet 4. At the bottom of the first flap 10 is located an indentation or groove 14. The purpose of the groove 14 is to provide strength to the bottom of the flap 10 so as to avoid tearing when the seal is separated. A score line 16 is formed adjacent the groove 14. The score line 16, as best shown in FIG. 3A, is scored approximately two-thirds of the way through the plastic of the upper laminate sheet 2. Periodically small webs 18 are positioned between the scores 20 so that accidental rupturing of the envelope will not occur without fracturing of the webs 18.
The first flap 10 is provided with perforation pop-outs 22 which are partially scored for ease in removal to form the perforation 24 as best shown in FIG. 4. The perforations 24 are provided for positioning the first flap 10 on the rings of a notebook binder (not shown).
As best shown in FIG. 4, half-moon shaped popouts 26 are provided at the lower corners of the first flap 10 for ease in breaking the seal of the envelope E. At the score line 16 are reinforcement seals 28 which abut the heat seal 8. The reinforcements 28 prevent tearing of the envelope E in the area of the popouts 26 due to frequent insertion or removal of the information originally sealed in the envelope E.
It should be noted, that the first flap 10, lies in the plane of the upper laminate sheet 2 and extends downward from the hinge 12. When the flap 10 is opened fully, it can be swung approximately 180.degree. about the hinge 12 which is located below the seal 8. The score line 16 extends from the bottom edge of the flap 10 upwardly on either side of the flap as at 30 and includes webbing (not shown) similar to the webs 18 located between the scores 20 of FIG. 3A. The hinge 12 and the heat seal in the areas of the score lines 30, prevent tearing off of the flap 10.
The first flap 10 is provided with a second flap or hanger 32 as best shown in FIG. 1. The second flap 32 includes a perforation popout 34 providing an opening 36 as best shown in FIG. 2. The opening 36 includes a recess 38 for supporting a hook 40 as shown in FIG. 2. A score line 42 similar to score line 16 is provided in the first flap 10 with webs similar to 18 shown in FIG. 3A. These score lines 18 as mentioned above, prevent premature rupturing of the score prior to the intended use of the second flap or hanger 32. It will be noted in FIG. 2 that the second flap 32 hinges on hinge line 12 as does also the first flap 10. It will be thus obvious that the hinge 12 of the second flap 32 is positioned below the seal 8. Thus, the second flap 32 when in use, will bend backward about the hinge 12 in the manner of the flap 10.
The opening 36 cooperates with the perforations 24 to provide, were necessary, a receptacle for a third ring in a standard three ring notebook binder. Thus, the opening 36 is in line with the perforations 24.
In FIG. 5, an insert 44 is shown positioned a portion of the way into the envelope E with the first flap 10 and second flap 32 hinged upwardly about the hinge 12. The notches 46 assist in making it easy to remove or insert any material such as the insert 44.
DESCRIPTION OF FIGS. 6 through 9
FIGS. 6 and 7 show a modified version of the invention with a second flap or hanger 48 which is provided with a triangular shaped opening 50. At the apex of the triangular opening 50, is positioned a hook 52 as in FIG. 6. In FIG. 6, the hinge line of FIGS. 1 through 5 is deleted and the second flap 48 hinges on the seal line 54.
As best shown in FIG. 6A, the upper sheet 56 is bonded to the lower 58 by a bond 60 formed by the indentation of the heat seal 62. Thus, the seal line 54 in the modification of FIGS. 6 and 7 is on the back of the envelope E at the area of the periphery of the lower sheet 58 rather than on the front of the envelope E as in FIGS. 1 through 5. The hinge for the first flap 64 as well as the second flap 48 is the seal area 60 differing from the structure shown in FIGS. 1 through 5.
DESCRIPTION OF FIGS. 8 and 9
In FIGS. 8 and 9, the first flap 66 includes a hanger second flap 68. The second flap 68 includes an opening 70 with a notch 72 for a hook 74. The hinge system of FIGS. 8 and 9 is similar to that of FIGS. 6 and 7 in that the hinge comprises the seal line as at 54 in FIGS. 6 and 7 as best shown in FIG. 6A. Both modifications shown in FIGS. 6 through 9 include perforated popouts similar to popout 34 and are scored with reinforcement webs similar to webs 18 and scores 20 shown in FIGS. 1 through 5.
Whereas the opening 50 is centered in the second flap 48 in FIGS. 6 and 7, the opening 70 has its upper edge as shown in FIG. 8, bordering on the hinge seal 54.
While this invention has been described as having a preferred design, it is understood that it is capable of further modifications, uses and/or adaptions of the invention following in general the principle of the invention and including such departures from the present disclosures as come within known or customary practice in the art to which the invention pertains, and as may be applied to the essential features hereinbefore set forth, and fall within the scope of the invention of the limits of the appended claims.
