ABSTRACT:
BACKGROUND OF THE INVENTION
The field of the invention is containers and the invention relates more particularly to reclosable plastic bags. Said bags typically have first and second strips adjacent the top thereof. These strips interlock to reclosably close and permit opening of the bag.
Plastic bags with a reclosable top of the type commonly sold under the trademark “ZIPLOC” bags are in widespread use. When one wants to place articles in such bags, it is often difficult to hold the top of the bag open. Such bags tend to move into a closed position and it takes two hands to maintain a wide opening to facilitate filling.
U.S. Pat. No. 5,027,965, shows a fuel overflow collection device. In one form, this device utilizes a plastic bag having one side larger than the other side and having a wire imbedded in a pouch formed in the bag. The bag is adhered under a fuel overflow vent to capture overflowing fuel and prevent it from entering the water way.
U.S. Pat. No. 5,174,658 shows a self-expanding and reclosable flexible bag. This bag has a pair of plastic stays which are made from a relatively stiff resilient material having a memory, such as Nylon or high-density polyethylene. The strips are shaped so that in an unstressed configuration they are circular or elliptical. Thus, when the bag is opened it will tend to form an almost circular opening to facilitate the filling or emptying of the contents of the bag.
There are many instances when one would like to have the “ZIPLOC” style bag stay open so that both hands could be used to fill the bag. Furthermore, it is sometimes desired to temporarily secure the bag over, for instance, a bottle opening to facilitate the transfer of the contents of a bottle, for instance, of pills into the plastic bag.
BRIEF SUMMARY OF THE INVENTION
It is an object of the present invention to provide bags, especially plastic bags, and predominantly reclosable plastic bags with an inelastically deformable member secured adjacent the opening of such bag or the reclosing strips of a bag which has a closure similar to that found in plastic bags sold under the trademark “ZIPLOC.” In this way, the bag may be deformed into a desired shape to assist in the filling or emptying of its contents.
The present invention is for a plastic bag of the type having a male and a female securement means near a top of an upper opening thereof. The improved plastic bag of the present invention has a first inelastically deformable member secured adjacent the opening along one side extending from the right end to the left end of the bag. Similarly, a second inelastically deformable member is secured adjacent the opening along the other side and also extends from the right end to the left end of the bag. The ends of the two inelastically deformable members are interlocked or fuzed within the plastic at the right and left ends thereof so that the right and left sides function together as an integral unit. The inelastically deformable members may be metal, such as iron or stainless steel, or a highly filled polymer which exhibits the property of inelastic deformability.
