Abstract

A case comprises a case cover (1), a case bottom (2) and zippers fixed between the case cover and the case bottom. The zippers comprise inner-layer and outer-layer zippers (31, 32) that are parallel to each other. Strip-shaped upper and lower extension surfaces (41, 42) are fixed respectively between the inner-layer zipper (31) and the case cover (1) and between the inner-layer zipper and the case bottom (2). Heights of the upper and lower extension surfaces (41, 42) are respectively greater than a distance between the outer-layer zipper (32) and the case cover (1) and a distance between the outer-layer zipper and the case bottom (2). The case uses inner-layer and outer-layer zippers (31, 32) to enlarge the capacity of the case, archive a double-sealing effect, and make the whole case more concise and attractive.

Description

Luggage technology

The utility model relates to a luggage, in particular to a luggage. Background technique

The bag generally includes a cover and a bottom of the case, and a zipper is provided between the cover and the bottom of the case for opening and closing the case. In order to increase the capacity of the luggage, the existing luggage generally has a sandwich on the upper part of the cover, and the zipper is also provided on the edge of the sandwich. When there are many things to be loaded, the zipper of the interlayer is pulled apart, and the interlayer can be unfolded, thereby expanding the luggage. capacity.

The interlayer of the existing bag is separated from the zipper of the opening and closing bag. One is that it looks unsightly and lacks the overall feeling; the other is that the expansion effect is general; the third is that the extra layer reduces the sealing performance of the bag. Utility model content

The technical problem to be solved by the utility model is to solve the problem that the existing bag expansion effect and the sealing performance are not good, and the appearance is not beautiful.

In order to solve the above technical problem, the technical solution adopted by the present invention is to provide a luggage box, including a box cover and a box bottom, and a zipper fixed between the two, the zipper includes inner and outer zippers parallel to each other, the inner zipper A strip-shaped upper and lower extending faces are respectively fixed between the layer zipper and the cover and the bottom of the box, and the heights of the upper and lower extending faces are respectively greater than the distance from the outer zipper to the cover and the bottom of the case. In the above bag, the upper and lower stretching faces are made of nylon.

In the above case, the cover and the bottom of the case are fixed together by a telescopic belt connection at the rear end thereof, and the inner and outer zippers are located inside the elastic band.

In the above bag, the elastic band is made of elastic nylon.

The bag provided by the utility model expands the capacity of the bag through the inner and outer zippers, realizes the sealing effect of the double seal, and the whole bag is more simple and beautiful. DRAWINGS

1 is a schematic structural view of an outer zipper of a bag provided in the present invention; FIG. 2 is a schematic structural view of an outer zipper of the bag provided in the present invention; FIG. 3 is a rear view of the bag provided by the utility model. . detailed description

The present invention will be described in detail below with reference to the accompanying drawings.

As shown in Fig. 1 and Fig. 2, the bag provided by the utility model comprises a box cover 1 and a box bottom 2 and a zipper fixed between the two, and the zipper comprises inner and outer zippers 31, 32 which are parallel to each other.

The upper zipper 31 and the box cover 1 and the box bottom 2 are respectively fixed with strip-shaped upper and lower extension surfaces 41 and 42. In the present embodiment, the upper and lower extension surfaces 41 and 42 are made of nylon, which can be folded and folded. And expand. The heights of the upper and lower extension faces 41, 42 are respectively greater than the distance of the outer zipper 32 to the cover 1 and the case bottom 2. After the outer zipper 32 is pulled open, the cover 1 can be lifted, and the upper and lower extended faces 41, 42 are unfolded, and the capacity of the entire bag is greatly increased, while the inner and outer zippers 31, 32 double seal the bag. The effect is better. In addition, the inner and outer zippers 31 of the utility model, Compared with the existing sandwich design, the design of 32 can reduce multiple processes in the production process, saving labor costs and improving production efficiency.

The cover 1 and the bottom 2 are connected and fixed by the retractable belt 5 at the rear end. In the present embodiment, the elastic band 5 is made of elastic nylon, which can be expanded and contracted according to the expansion of the bag capacity. The inner and outer zippers 31, 32 are located inside the telescopic belt 5, so that after the outer zipper 32 is pulled, the inner zipper 31 is not visible from the outside, and the inner and outer zippers 31, 32 are not visible from the rear. The combination of the whole box is simple and beautiful, and the overall is strong.

The bag provided by the utility model expands the capacity of the bag through the inner and outer zippers 31, 32, realizes the sealing effect of the double-layer seal, and the whole bag is more simple and beautiful. The present invention is not limited to the above-described preferred embodiments, and any person should be aware of the structural changes made in the light of the present invention. Any technical solutions having the same or similar as the present invention fall into the protection of the present invention. Within the scope.
