Definitions
- closure devices for fastening storage containers, including plastic bags
- closure devices made of plastic materials is generally known to those skilled in the art, as demonstrated by the numerous patents in this area.
- closure devices are in connection with flexible storage containers, such as plastic bags.
- the closure device and the associated container are formed from thermoplastic materials, and the closure device and the sidewalls of the container are integrally formed by extrusion as a single piece.
- the closure device and sidewalls of the container may be formed as separate pieces and then connected by heat sealing or any other suitable connecting process. In either event, such closure devices are particularly useful in providing a closure means for retaining matter within the bag.
- closure devices typically utilize mating fastening strips or closure elements which are used to selectively seal the bag. With such closure devices, however, it is often difficult to determine whether the fastening strips are fully occluded. This problem is particularly acute when the strips are relatively narrow. Accordingly, when such fastening strips are employed, there exists a reasonable likelihood that the closure device is at least partially open.
- Such fastening strips devices are also particularly difficult to handle by individuals with limited manual dexterity.
- the prior art has also provided sliders for use in opening and closing the fastening strips, as disclosed, for example, in U.S. Patent Nos. 4,199,845, 5,007,142, 5,007,143, 5,010,627, 5,020,194, 5,070,583, 5,283,932, 5,301,394, 5,426,830, 5,431,760, 5,442,838, and 5,448,808.
- Some of these sliders include a separator which extends at least partially between the fastening strips. When the slider is moved in the appropriate direction, the separator divides the fastening strips and opens the bag.
- the fourth knurled surface is located below the second fastening strip.
- a first rib of a first color is located above the first fastening strip.
- the first rib is located on the inside surface of the first sidewall.
- a second and third rib of a second color are located above the second fastening strip.
- the second and third rib are located on the inside surface of the second sidewall.
- Another plastic bag which has first and second fastening strips and ribs has been sold by Dow under the trademark Ziploc®.
- Five ribs are located on the inside surface of a first sidewall of the bag. The five ribs are located above the first fastening strip.
- Seven ribs are located on the inside surface of a second sidewall of the bag. The seven ribs are located above the first fastening strip.
- the bag does not have and does not use a slider.
- Moving the slider is a two hand operation with one hand moving the slider and the other hand holding the bag. If the fingers of the user are slippery due to handling various items, the fingers will slip along the bag. Similarly, even if the user's fingers are clean, the fingers may slip along the bag.
- the container includes a bag, a closure device and a gripping surface.
- the bag includes a pair of complementary sheets or opposing flexible sidewalls, such as a plastic bag.
- the closure device includes interlocking fastening strips disposed along respective edge portions of the opposing sidewalls, and a slider slidably disposed on the interlocking fastening strips for facilitating the occlusion and deocclusion of the fastening strips when moved towards first and second ends of the fastening strips.
- the gripping surface is located on the sidewall of the bag below the fastening strips.
- the gripping surface includes an upper surface and a lower surface. The gripping surface is provided to assist the user in the opening and closing of the closure device and/or to facilitate the storage and retrieval of matter inside the bag.

- Suitable thermoelectric devices include heated rotary discs, traveling heater bands, resistance-heated slide wires, and the like.
- the connection between the film and the fastening strips may also be established by the use of hot melt adhesives, hot jets of air to the interface, ultrasonic heating, or other known methods.
- the bonding of the fastening strips to the film stock may be carried out either before or after the film is U-folded to form the bag. In any event, such bonding is done prior to side sealing the bag at the edges by conventional thermal cutting.
- the first and second fastening strips may be positioned on opposite sides of the film. Such an embodiment would be suited for wrapping an object or a collection of objects such as wires.
- the first and second fastening strips should usually be positioned on the film in a generally parallel relationship with respect to each other, although this will depend on the intended use.
- the slider may be multiple parts and snapped together. In addition, the slider may be made from multiple parts and fused or welded together.
- the slider may also be a one piece construction.
- the slider can be colored, opaque, translucent or transparent.
- the slider may be injection molded or made by any other method.
- the slider may be molded from any suitable plastic material, such as, nylon, polypropylene, polystyrene, acetal, toughened acetal, polyketone, polybutylene terrephthalate, high density polyethylene, polycarbonate or ABS (acrylonitrile-butadiene-styrene) .
