Benefits of technology

This patent describes a plastic bag with two panels that can be sealed to prevent access to the bag interior. The bag can also be resealed to repeatedly open and close without damaging the bag. The sealing structure is made of a permanent adhesive layer and a release liner strip, which can be removed to access the bag interior. The permanent adhesive layer and release liner strip allow for repeated and nondestructive access to the bag interior before it is permanently sealed.

Problems solved by technology

However, an initially sealed bag may not be preferable, because repeated use of the bag before permanent sealing may be desired.

Embodiment Construction

[0012]Referring to FIGS. 1 and 2, a sealable bag is shown generally at 10. The sealable bag 10 includes coextensive front and panels 12 and 14, respectively (broadly, first and second panels). The panels 12, 14 are joined at the bottom and sides of the bag 10. In one embodiment, the panels 12, 14 are formed as a single sheet of material that is folded at the bottom of the bag 10 along a linear fold 16. The side edges are joined together by fusion lines 18 and 20. The panels 12, 14 can be joined in other manners within the scope of this invention. For example, the panels may be formed as separate sheets and fused together along the bottom and side edges. Whether the panels are formed as one piece and folded over, or formed as two pieces, the edges are considered to be “joined” together for purposes of this description. Furthermore, in some embodiments, the panels 12, 14 may not be coextensive. For example, the top of one of the panels can extend above the top of the other panel.

Abstract

A sealable plastic bag has a first panel and a second panel. The first panel and second panel are joined along three edges to define a bag interior and an opening to permit access to the bag interior. A permanent sealing structure is configured to permanently seal the first and second panels to close the opening and prevent access to the bag interior. A release liner strip overlies the permanent sealing structure to prevent the permanent sealing structure from sealing the first and second panels until activation by a user. A resealable sealing structure is configured to repeatedly and nondestructively seal the first and second panels to close the opening and prevent access to the bag interior.

Description

FIELD OF THE INVENTION[0001]The present invention generally relates to sealable bags, and more specifically, a plastic bag that includes both permanent and temporary sealing structures.BACKGROUND OF THE INVENTION[0002]Sealable bags are used for many different applications, such as shipping, food packaging, biohazard disposal, etc. Sealable bags generally include a permanent or a temporary sealing structure, depending on the application. Some sealable bags include a peelable seal, or a permanent seal that must be unsealed before the bag can be used. Other sealable bags include a permanent seal or fusion seal that must be removed from the bag to permit access to the interior of the bag. However, an initially sealed bag may not be preferable, because repeated use of the bag before permanent sealing may be desired.SUMMARY OF THE INVENTION[0003]In one aspect of the present invention, a plastic bag generally comprises a first panel having four edges, and a second panel having four edges. ...
