Abstract

A device of integral construction having resilient elongated members and a curved hook handle for easy and simple operation. The bad closure device of the present invention comprises smooth surfaces to accept LDPE manufactured bread and other consumable container bags and a smooth curved member located at thumb level for easy and quick release of same. The gripping characteristics of the closure device is achieved by a flexible spring tab that applies constant tension to the bag-accepting area.

Description

BACKGROUND OF THE INVENTION

1. Field of Invention
This invention relates to a closure device and more particularly for closing produce bags made of LDPE (Low Density Polyethylene) and those closures having smooth resilient jaws capable of quickly gripping and releasing the necks of said bags.
2. Description of the Related Art
Many bag closure devices have been issued patents. Although innovative and well meaning the vast majority of these devices are too complicated, inconvenient, difficult to use, and/or do not accomplish the desired result of the user. The majority of the inventions in the related art just have not received widespread acceptance and use by the consumer. The current and most widely used closure devices, ones that accompany bread products shipped in LDPE bags, are small plastic-encased wires or small, thin, plastic V-clips. The wire closures are clumsy at best and aggravating, awkward, and slow at worst in opening/closing bread bags, as well as virtually ineffective in keeping the bags airtight and the bread fresh. These tie-wires can be very annoying and a nuisance—especially if the previous user was left-handed. A right-handed person will then be tightening the wire when attempting to open the bag. V-clips often tear the bag and never close it properly as well as breaking apart after continued use. In addition, these wires and V-clips are so small that when dropped or misplaced they are almost impossible to find.

SUMMARY OF THE INVENTION

All breads and many other consumables come packaged in clear LDPE (Low Density Polyethylene) bags. This invention is an inexpensive, durable, never failing device that offers an unencumbered, simple, quick, convenient, easy, and the efficient opening and closing of said polyethylene bags as well as superior and complete airtight closure of same.
This invention can be used effortless by both left-handed and right-handed people. This invention is big enough to be seen by the visually impaired but small enough that a small child can use with ease. This invention can be used comfortably by people suffering from arthritis, by the elderly, as well as other mildly handicapped individuals. This invention is child safe—it has no sharp edges and is not small enough to swallow. Because of its rigid, although resilient, construction and design, unless it gets dropped behind the refrigerator, dropped in a fire, or taken out by the dog and buried in the backyard,—it will practically last forever. There is no built in obsolescence—so far the only marketing drawback I have found.

OBJECTS AND ADVANTAGES

Several objects and advantages of the present invention are:

- a) to provide a bag closure and opening device that is simple, easy, quick, and efficient for all that use it;
- b) to provide a device with no complex or moving parts;
- c) to provide a closure that insures superior and complete air-tight closure of bread bas or the like;
- d) to provide a closure that all can afford;
- e) to provide a closure that is so durable that it will last for years with continuous daily use;
- f) to provide a closure that can be used by the elderly, the mildly handicapped, the mentally challenged, and children;
- g) to provide a closure for the vision impaired;
- h) to provide a closure that has no sharp edges, teeth, or prongs;
- i) to provide a closure that is child safe.

DETAILED DESCRIPTION OF THE INVENTION

Referring more specifically to the drawings and photos a closure device 10 for closing and the quick opening of LDPE (Low Density Polyethylene) bags such as bread products and other consumables that are packaged and shipped. The closure device is manufactured by injection molding using polypropylene plastic resin and can be manufactured in an array of colors. This material is more specifically an “impact” modified copolymer. This insures the longevity of the invention as well as contributes to its effectiveness in operation and achieving the goal for which it is designed.
The closure device 10 of FIG. 1 is comprised of an elongated, generally flat body structure, 4 inches in length, ¼ inches in width, and 1¼ inch in thickness and comprising a comfortable hook handle 3, two juxtaposed jaws, lower jaw 4 and upper jaw 1. mouth 3, and throat lock 5.
As shown throughout the figures and photos, a closure device according to the invention has a spring tab 8 (FIG. 2) that is locked into locking groove 6 prior to shipping. This embodiment is an improvement over previous prototypes of this invention in that it provides continuous pressure on the throat lock 5 while engaged in gripping the neck of the bag. This embodiment also insures that after countless uses the upper jaw 1 and lower jaw 4 b do not weaken and therefore become ineffective.
The user, whether right-handed or left-handed, curls the forefinger over hook handle 3 and engages the twisted top of the bread bad in between upper jaw 1 and lower jaw 4 at mouth 2. With opposing pressure—from the closure device and the bread bag, the neck of the bag is brought into mouth 2 and locked into the throat lock 5.
FIG. 1 illustrates an embodiment 1 of the present invention in that the upper jaw 1 is curved approximately 45 degrees upward and away from the lower jaw 4. Other than allowing a large neck bag to enter into throat lock 5 this curved embodiment allows the user to quickly release the neck of the bag. With the thumb of the hand using the device the user may simply apply upward pressure on the upper jaw 1 and the neck is released immediately.
Referring to all Figures and Photos a closure device according to this invention has no sharp edges, no moving parts to ever replace, and needs no maintenance to insure effectiveness, simplicity, and quickness in utilizing said invention for its intended purpose.
The foregoing description is meant to be exemplary only and should not limit the scope of the invention set forth in the following claims.
