Description

Technical Field

[0001] This utility model patent relates to the technical field of zipper bags, and in particular to a scratch-resistant structure for zipper bags. Background Technology

[0002] Slanted pockets typically feature a 60° angle design. When paired with a zipper, the opening faces upwards. This design, combined with ergonomic design, reduces the pressure on the bottom of the pocket when reaching in, minimizing hand contact with the upper part of the opening and reducing the likelihood of the back of the hand or little finger directly hitting the zipper pull at the bottom, thus improving comfort. Vertical pockets, on the other hand, have an angle of ≥90° with the opening facing horizontally or downwards. This increases the contact area between the hand and the zipper, making it easier to touch the zipper pull at the bottom. This is especially noticeable with zippers made of harder metals, where the scraping sensation from the hard zipper teeth on the back of the hand is more pronounced. In cold environments, the excellent thermal conductivity of metal draws heat away from the body, resulting in a noticeable foreign body sensation and cold irritation, negatively impacting the user experience and limiting clothing design options.

[0003] We have designed a scratch-resistant structure that reduces the feeling of foreign objects in zippered pocket inserts without changing the direction of the insert, improves the comfort of rigid zipper components in insert pocket applications, and provides more options for clothing design. Utility Model Content

[0004] The purpose of this utility model is to solve the existing technical problems by proposing a scratch-resistant structure for zipper bags, which can be adapted to the design of zipper bags for various types of clothing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a scratch-resistant structure for a zipper bag, comprising a zipper assembly fixed to the bag opening, wherein when the zipper assembly is opened, a zipper opening is formed that communicates with the inner cavity of the zipper bag, the two long sides of the zipper opening being the back of the hand and the palm side, respectively, and a scratch-resistant structure extending towards the center of the zipper opening is provided on the inner side of the zipper assembly, the scratch-resistant structure comprising a scratch-resistant long strip provided along the back of the hand and a scratch-resistant short strip fixed at the bottom stop of the zipper; the scratch-resistant long strip includes a scratch-resistant long side partially exposed outside the zipper opening, and a first buffer gap is left between the scratch-resistant long side and the back of the hand; the scratch-resistant short strip includes a scratch-resistant short side partially exposed outside the zipper opening, and a second buffer gap is left between the scratch-resistant short side and the bottom stop of the zipper, the length of the second buffer gap being greater than the length of the zipper head.

[0006] Preferably, the bag opening is oriented horizontally or diagonally downwards.

[0007] Preferably, the anti-scratch long strip and anti-scratch short strip are connected as one piece, and the anti-scratch structure is an L-shaped gasket; the anti-scratch structure is sewn or seamlessly connected to the inside of the zipper assembly.

[0008] Preferably, the anti-scratch long strip and the anti-scratch short strip are set separately, with the anti-scratch short strip being clamped between the anti-scratch long strip and the zipper assembly, so that a thickness gap is left between the zipper assembly and the anti-scratch long strip.

[0009] Preferably, the zipper assembly includes a back zipper tape, a palm zipper tape, and a zipper head for zipping and engaging. The palm zipper tape includes a palm fabric tape and palm chain teeth, and the front projection portion of the anti-scratch strip covers the palm chain teeth.

[0010] Preferably, the opening is located on the main body, and the stiffness of the anti-scratch structure is greater than that of the main body fabric.

[0011] The beneficial effects of this utility model are: by providing a buffer gap through the anti-scratch structure extending towards the zipper opening, the back of the consumer's hand and the lower stop position directly contact the anti-scratch structure when reaching into the bag, effectively reducing the scratchy feeling and cold stimulation caused by the hand contacting the concave and convex surfaces of the zipper assembly; the anti-scratch structure can be assembled together with the bag opening process, which is convenient for workshop production; the anti-scratch structure is compatible with slanted pockets, vertical pockets, flat pockets and other pocket structures, and has wide applicability.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Combined with Examples 1-2 and Appendix Figure 1-6A scratch-resistant structure for a zippered bag includes a zipper assembly 2 fixed to the opening 1. When opened, the zipper assembly 2 forms a zipper opening 20 communicating with the inner cavity of the zippered bag. The two long sides of the zipper opening 20 are a back-of-hand side 201 and a palm side 202. A scratch-resistant structure extending towards the center of the zipper opening 20 is provided on the inner side of the zipper assembly 2. The scratch-resistant structure includes a long scratch-resistant strip 32 along the back-of-hand side 201 and a short scratch-resistant strip 31 fixed to the bottom stop of the zipper. The long scratch-resistant strip 32 includes... The long anti-scratch edge 321 is partially exposed outside the zipper opening 20, and a first buffer gap 320 is left between the long anti-scratch edge 321 and the back of the hand edge 201; the short anti-scratch strip 32 includes a short anti-scratch edge partially exposed outside the zipper opening 20, and a second buffer gap 312 is left between the short anti-scratch edge and the bottom stop 24 of the zipper. The length of the second buffer gap 312 is greater than the length of the zipper head 23, so that when the zipper head is in the bottom stop position, the short anti-scratch edge contacts the skin of the hand first, providing cushioning for the hand.

[0015] Furthermore, depending on the length of the zipper opening 20, the second buffer gap 312 can be 0.3-1cm longer than the length of the zipper head.

[0016] Furthermore, the scratch-resistant structure can be formed by cutting or laser cutting the fabric. The cutting process is finished with smooth edges so that the seams of the long and short scratch-resistant strips are not exposed, ensuring a comfortable experience for consumers when putting their hands into the bag.

[0017] The anti-scratch structure for zippered bags has the opening 1 facing horizontally or diagonally downward, suitable for vertical pocket designs on the main body; the opening 1 can also face diagonally upward, suitable for diagonal pocket designs.

[0018] For the anti-scratch structure of the zipper bag, the zipper assembly 2 includes a back zipper tape, a palm zipper tape and a zipper head 23 for zipping and matching. The palm zipper tape includes a palm fabric tape 221 and a palm chain tooth 222. The front projection of the anti-scratch strip covers the palm chain tooth 222.

[0019] Furthermore, the width of the first buffer gap 312 can be 0.1-1cm depending on the width of the chain teeth in the palm.

[0020] The scratch-resistant structure used in zippered bags has the opening located on the main body. The stiffness of the scratch-resistant structure is greater than that of the main body fabric, ensuring the shaping effect of the scratch-resistant structure and providing a stable cushioning layer to reduce the scratchy feeling and cold stimulation caused by the zipper teeth and the bottom stop of the zipper head on the back of the hand.

[0021] Example 1 The scratch-resistant structure for zipper bags consists of a long scratch-resistant strip 32 and a short scratch-resistant strip 31 connected together, with an L-shaped gasket 30 as the scratch-resistant structure. The L-shaped gasket 30 is sewn inside the zipper assembly, allowing it to be sewn through the bag opening along with the main body. The stitching passes between the bag opening, the zipper assembly, and the L-shaped gasket, facilitating workshop production. Seamless connection can be achieved through ultrasonic heat pressing or adhesive bonding. The L-shaped gasket has a pre-set L-shaped fixing area, the outer side of which is attached to the zipper assembly.

[0022] Furthermore, the corners of the L-shaped gasket 30 can be rounded to assist in the positioning of the L-shaped gasket inside the zipper assembly and prevent the L-shaped gasket from being accidentally clamped when the zipper assembly is opened and closed.

[0023] Furthermore, L-shaped gaskets can be formed by laser cutting a single layer of fabric.

[0024] Example 2 The anti-scratch structure for zippered bags features a separate anti-scratch strip 32 and an anti-scratch strip 31. The anti-scratch strip 31 is clamped between the anti-scratch strip 32 and the zipper assembly 2, creating a thickness gap between the zipper assembly 2 and the anti-scratch strip 32. This prevents the anti-scratch strip from being accidentally caught when the zipper assembly opens and closes.

[0025] Furthermore, both the anti-scratch strip 32 and the anti-scratch strip 3 are rectangular.

[0026] Furthermore, the anti-scratch structure can be formed by sandwiching a stiff fabric with the main body fabric. The stiff fabric can be selected from denim, canvas or polyester fiber fabric, etc. The double-folded part after being sandwiched is set towards the back of the hand edge 201, so that the rough seam is fixed to the inside of the back of the hand fabric strip. The stitching is passed between the opening 1, the zipper assembly 2, the anti-scratch short strip 31 and the anti-scratch long strip 32 to form a fixed stitch, which is located on the outer periphery of the zipper opening.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
