DETAILED DESCRIPTION
[0024] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.
[0025] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.
[0026] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides a plastic ziplock bag, comprising a plastic bag body 100 , a male buckle strip 200 arranged on one side of the opening of the plastic bag body 100 , and a female buckle strip 300 arranged on the other side of the opening of the plastic bag body 100 .
[0027] The male buckle strip 200 has two parallel convex strips 210 and a sealing strip 220 disposed between the two convex strips 210 . The ends of the two convex strips 210 are provided with outer protrusions 211 extending along the length direction. The sealing strip 220 is preferably made of rubber.
[0028] The female buckle strip 300 has a buckle groove 310 extending in the length direction, and a boss 320 arranged in the middle of the bottom of the buckle groove 310 and extending in the length direction. An inner protrusion 311 extending in the length direction is arranged on the opposite inner side of the end of the buckle groove 310.
[0029] The two convex strips 210 of the male buckle strip 200 are buckled into the buckle groove 310 of the female buckle strip 300, and the outer protrusions 211 on each convex strip 210 are respectively hooked with the inner protrusions 311 on both sides of the buckle groove 310, and the boss 320 is embedded between the two convex strips 210 and pressed against the sealing strip 220.
[0030] When the two convex strips 210 of the male buckle strip 200 are buckled into the buckle groove 310 of the female buckle strip 300, the outer protrusions 211 on the two convex strips 210 are respectively hooked together with the inner protrusions 311 on both sides of the buckle groove 310, so that the male buckle strip 200 and the female buckle strip 300 are buckled together and not easily separated, thereby realizing the sealing of the plastic bag. When the male buckle strip 200 and the female buckle strip 300 are buckled together, the boss 320 in the buckle groove 310 is embedded between the two convex strips 210 and pressed against the sealing strip 220, which can improve the sealing of the plastic bag.
[0031] In one embodiment, referring to Figure 3 and Figure 4 The boss 320 is a trapezoidal platform that gradually narrows from the root to the end, so that it is easy to insert the boss 320 between the two convex strips 210.
[0032] Preferably, a trapezoidal groove 321 cooperating with the trapezoidal platform is provided on the outer side of the sealing strip 220 along the length direction. When the male buckle strip 200 and the female buckle strip 300 are engaged, the trapezoidal platform is stuck in the trapezoidal groove 321, which can increase the contact area between the trapezoidal platform and the sealing strip 220 and further improve the sealing performance of the seal.
[0033] In one embodiment, referring to Figure 1 and Figure 3 The plastic ziplock bag further comprises a U-shaped clip 400, which is preferably made of plastic and is clamped and fixed outside the opening of the plastic bag body 100 along the length direction. By clamping the U-shaped clip 400 outside the opening of the plastic bag, not only can the opening of the plastic bag be prevented from being accidentally opened, but the male buckle strip 200 and the female buckle strip 300 can also be clamped by the U-shaped clip 400, thereby further improving the sealing performance of the seal.
[0034] Preferably, a card slot 410 is provided on the relative inner sides of the two side walls of the U-shaped clip 400, and the card slots 410 on both sides of the U-shaped clip 400 are respectively clamped in the positions corresponding to the male buckle strip 200 and the female buckle strip 300 outside the opening of the plastic bag body 100, so that the U-shaped clip 400 is not easy to fall off when clamped outside the opening of the plastic bag.
[0035] In one embodiment, referring to Figure 1 and Figure 2 In order to facilitate carrying the plastic bag by hand, straps 500 are provided on both sides of the plastic bag body 100 .
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
