Description

Technical Field

[0001] The utility model relates to the technical field of zippers, and more specifically to a socket for a zipper. Background Art

[0002] The zipper socket is usually fixed at the starting end of one of the zipper tapes. This socket is mainly made by resin injection molding, that is, molten resin is injected into the mold cavity from the gate. After curing, the resin will solidify in the gate. When the resin on the gate is separated from the socket, a gate mark will be formed on the socket.

[0003] To make the gate mark less noticeable, patent application number 201380080096.0 discloses a socket for a zipper opening member, which comprises: a seat rod arranged parallel to the front of the insert rod; and a socket body having an insert rod hole for inserting the rear portion of the insert rod, and a zipper tape groove connected to the insert rod hole formed on one of the left and right side surfaces of the socket body. Furthermore, a gate mark is provided behind the width of the zipper tape groove of the socket body. Alternatively, a side recessed portion connected to the zipper tape groove may be provided behind the extension direction of the zipper tape groove, and a flat portion may be provided on the peripheral portion of the side recessed portion and the portion along the zipper tape groove, with a gate mark provided on the bottom surface of the side recessed portion.

[0004] While the presence of gate marks on the left and right side surfaces of the socket body, either in a dimly lit space, or in a dimly lit space, where the zipper tape groove extends behind the zipper tape groove, or the presence of gate marks on the bottom surface of the side recess, where the zipper tape groove is continuous with the side recess, creating a sense of unity, is not likely to be noticeable, both of these gate marks are located on the side surfaces of the zipper tape groove (or the side recess) in the direction of extension, which can still draw attention during actual use, especially in well-lit environments, resulting in a poor user experience for consumers. To address this issue, we provide a zipper socket. Utility Model Content

[0005] The utility model provides a socket for a zipper, the main purpose of which is to overcome the defect that the gate residue of the existing socket is exposed on the side behind the extension direction of the zipper belt groove, which still attracts people's attention in a well-lit environment and brings a bad user experience to consumers.

[0008] In a preferred embodiment, the partition portion has a first partition wall on a side facing the zipper tape groove, and a second partition wall on a side away from the zipper tape groove, wherein the second partition wall forms a side wall or a part of a side wall of the recess.

[0009] In a preferred embodiment, the gate remnant is provided at the bottom of the recess adjacent to the second partition wall or at the bottom of the recess located beside the second partition wall.

[0010] In a preferred embodiment, the gate remnant is provided within the range of the projection of the second partition wall on the bottom surface of the recessed portion.

[0011] In a preferred embodiment, the recess is a groove or a notch with an opening. The groove is preferably square, arc-shaped or strip-shaped.

[0012] In a preferred embodiment, the opening of the notch is located on a side away from the partition portion and is located at the end of the side surface of the socket body behind the extending direction of the zipper tape groove.

[0013] In a preferred embodiment, the notch groove is provided with a first side wall and a second side wall in the direction of the width of the zipper tape groove, and the distance between the first side wall and the second side wall is equal to the width of the zipper tape groove.

[0014] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following beneficial effects: the socket structure has a recessed portion behind the zipper tape slot in the direction of extension, the gate residue is located within the recessed portion, and the zipper tape slot and the recessed portion are separated by a partition, so that the gate residue is hidden within the recessed portion. Since the socket is primarily used on the user side of the socket body where the zipper tape slot is provided, the partition blocks the user's view, making the gate residue truly inconspicuous, thereby improving product quality and the user experience.
