Description

Technical Field

[0001] This application relates to the field of zipper technology, specifically to a zipper pull tab with a hidden, detachable cutter and a self-adhesive zipper. Background Technology

[0002] Zippers are widely used connectors in daily life, and are widely used in clothing, bags, tents, packaging and other fields. In many applications, such as express delivery packaging bags, disposable protective equipment, and temporary sealing devices, zippers are often required for opening and closing operations, and it is desirable for zippers to be able to easily cut through the outer packaging or sealing material for quick opening.

[0003] For adhesive zippers that can be attached to packaging bags or protective films, once attached, the zipper cannot directly create a passage for people or objects to pass through because the surface to which it is attached does not have an opening. Users need to find a knife to cut an opening on the surface to attach the zipper. Creating an opening will be difficult if users do not have a knife with them. Summary of the Invention

[0004] In view of the above problems, this application provides a zipper pull tab with a hidden detachable cutter and a self-adhesive zipper to solve the problem that existing zippers may require additional cutters during use.

[0027] Zippers are widely used connectors in daily life, and are widely used in clothing, bags, tents, packaging and other fields. In many applications, such as express delivery packaging bags, disposable protective equipment, and temporary sealing devices, zippers are often required for opening and closing operations, and it is desirable for zippers to be able to easily cut through the outer packaging or sealing material for quick opening.

[0028] For self-adhesive zippers, good ease of opening and closing enhances the user experience and improves operational efficiency. Precise cutting guidance helps ensure operational reliability in complex environments, improving the consistency and safety of sealing and opening operations.

[0029] The inventors of this application have noticed that currently common zipper pulls often only have a simple pulling function. When the zipper is attached to a surface that requires cutting the outer material to create a zipper opening and closing channel, the operator has to find scissors or knives to cut the material surface to create the channel. This operation method not only leads to low efficiency, but also poses safety hazards in carrying and storing the extra tools, seriously affecting the convenience and safety of use.

[0030] To address the aforementioned technical problems, the inventors of this application, through research, designed a zipper pull tab with a concealed, detachable cutter and a self-adhesive zipper. By designing a structure including a pull tab base and an insert, the insert is inserted and secured through an insertion port in the pull tab base. One end of the insert has a cutter, and the other end has a step to restrict the insertion position, thus concealing the cutter within the pull tab base and integrating pull tab pulling with cutting. This method achieves concealed storage and detachable use of the cutter, effectively avoiding the need to carry additional tools. Furthermore, the structure is streamlined and compact, significantly improving ease of use and safety.

[0031] Please refer to Figures 1 to 4 , Figure 1 This is a three-dimensional structural diagram of a zipper pull tab with a hidden, detachable cutter provided in an embodiment of this application. Figure 2 This is an exploded view of a zipper pull tab with a hidden, detachable cutter, provided in an embodiment of this application. Figure 3This is an exploded view of a zipper pull tab with a hidden, detachable cutter, provided in an embodiment of this application. Figure 4 This is a front view of a zipper pull tab with a concealed, detachable cutter, provided as an embodiment of this application. (See attached image.) Figure 1-4 As shown, one embodiment of this application provides a zipper pull tab 1100 with a hidden detachable cutter, including: a pull tab base 100 and an insert 200; the pull tab base 100 is used to connect to the zipper and be squeezed and pulled by a person, the pull tab base 100 has a hollow structure, one side of the pull tab base 100 is open to form an insertion port 110, the insert 200 is used to be inserted into the insertion port 110 and fixed in the pull tab base 100; one end of the insert 200 is provided with a cutter 210, and the other end of the insert 200 is laterally protruded to form a step 220, the step 220 is used to abut against the edge of the insertion port 110 when the insert 200 is inserted into the insertion port 110 to limit the insertion position of the insert 200.

[0032] The pull tab holder 100 and the insert 200 are the core components of the zipper pull tab 1100 with a hidden, detachable cutter. The pull tab holder 100 is designed to connect to the zipper and be pulled by a user. It has a hollow structure, with one side open to form an insertion port 110, providing an insertion channel and space for the insert 200. The insert 200 is designed to be inserted into and fixed within the pull tab holder 100 through the insertion port 110. One end has a cutter 210 for cutting, and the other end has a horizontally protruding step 220, which abuts against the edge of the insertion port 110 during insertion to limit the insertion position.

[0033] In actual use, the operator inserts the insert 200 into the insertion port 110 of the pull tab holder 100. When the insert 200 is inserted until the step 220 abuts against the edge of the insertion port 110, the insert 200 is fixed and secured within the pull tab holder 100. At this time, the cutter 210 is hidden and stored inside the pull tab holder 100. The overall appearance of the pull tab is no different from that of an ordinary zipper pull tab, and the zipper can be opened and closed normally by pinching and pulling. When the cutter 210 needs to be used, the operator can pinch the exposed part of the insert 200 and pull it out from the insertion port 110, hold the pull tab holder 100, and use the cutter 210 at the end of the insert 200 for cutting.

[0034] It should be noted that the pull tab holder 100, as a component for storing the insert 200, can have various shapes, such as round, oval or any other shape, as long as it has space inside for the insert 200 to be inserted and stored. This application embodiment does not impose any special limitations on this.

[0035] In the actual application scenario of this application, the pull tab seat 100 is made of metal die casting, and the cutter 210 and insert 200 are made of plastic encapsulation injection molding. Similarly, the embodiments of this application do not impose special limitations on the process and manufacturing method of the pull tab seat 100, the cutter 210 and the insert 200.

[0036] By setting a hollow pull tab base 100 and a detachable insert 200, and setting a cutter 210 at one end of the insert 200 and a step 220 at the other end, the zipper pull tab 1100 with a hidden detachable cutter provided in this application embodiment can hide and store the cutter 210 and remove it as needed when in use, without the need to carry an additional cutting tool. Moreover, the limiting effect of the step 220 ensures the accuracy and stability of the insertion position of the insert 200. The structure is simple and compact, which significantly improves the convenience and safety of use.

[0037] Please continue to refer to Figures 1 to 4 According to some embodiments of this application, such as Figures 1 to 4 As shown, the step 220 is provided with anti-slip protrusions 221 that are perpendicular to the insertion direction of the insert 200.

[0038] The anti-slip protrusion 221 is an anti-slip component on the step 220 of the insert 200. Its purpose is to increase the friction between the operator's fingers and the step 220, facilitating the insertion and removal of the insert 200. In terms of connection, the anti-slip protrusion 221 is located on the step 220 and is perpendicular to the insertion direction of the insert 200.

[0039] In actual use, when the operator needs to pull the insert 200 out of the pull plate seat 100, the finger presses against the step 220 and applies force. The anti-slip protrusion 221 forms a large frictional resistance with the finger, preventing the finger from slipping and allowing the insert 200 to be pulled out smoothly.

[0040] By providing anti-slip protrusions 221 perpendicular to the insertion direction on the step 220, the zipper pull tab 1100 with a hidden detachable cutter provided in this application embodiment effectively improves the operational reliability of disassembling the insert 200 during use, avoids the risk of disassembly difficulties or accidental scratches caused by finger slippage, and enhances the user experience.

[0041] Please continue to refer to Figures 1 to 4 According to some embodiments of this application, such as Figures 1 to 4As shown, at least one side of the pull tab holder 100 adjacent to the insertion port 110 is provided with a card interface 120. At least one side of the insert 200 corresponding to the card interface 120 is provided with a resilient snap-fit ​​portion 230 that protrudes laterally. When the insert 200 is inserted into the pull tab holder 100 along the insertion port 110, the resilient snap-fit ​​portion 230 extends at least partially outward from the card interface 120 to fix the insertion position of the insert 200 in the pull tab holder 100.

[0042] The card interface 120 and the flexible snap-fit ​​portion 230 are the core components for detachably fixing the insert 200 to the pull tab seat 100. The card interface 120 is designed to provide an extension channel for the flexible snap-fit ​​portion 230, and it is located on at least one side of the pull tab seat 100 adjacent to the insertion port 110. The flexible snap-fit ​​portion 230 is designed to cooperate with the card interface 120 to achieve snap-fit ​​fixing of the insert 200, and it is located on at least one side of the insert 200 corresponding to the card interface 120, protruding laterally.

[0043] In actual use, when the insert 200 is inserted into the pull tab holder 100 along the insertion port 110, the elastic locking part 230 undergoes elastic deformation under the pressure of the inner wall of the pull tab holder 100. As the insert 200 continues to be inserted, when the elastic locking part 230 moves to the card interface 120 position, the elastic restoring force causes it to extend at least partially outward from the card interface 120 and form a locking with the edge of the card interface 120, thereby fixing the insert 200 inside the pull tab holder 100. When disassembly is required, the operator presses the extended elastic locking part 230 to disengage it from the card interface 120, and the insert 200 can be pulled out.

[0044] By providing a card interface 120 on the pull tab seat 100 and an elastic snap-fit ​​part 230 on the insert 200, the zipper pull tab 1100 with a hidden detachable cutter provided in this application embodiment enables quick snap-fit ​​fixing and convenient disassembly of the insert 200 and the pull tab seat 100 during use. The fixing is reliable and the operation is simple, avoiding accidental detachment of the insert 200 during pulling and improving the stability of use.

[0045] Please continue to refer to Figures 1 to 4 According to some embodiments of this application, such as Figures 1 to 4 As shown, the projection of the cutter 210 onto a plane perpendicular to the insertion direction of the insert 200 lies in the plane of the insert 200 near the cutter 210.

[0046] The projection position of the cutter 210 is part of the structural design of the arrangement of the insert 200 and the cutter 210. Its purpose is to ensure that the cutter 210 does not extend beyond the end plane of the insert 200 in a plane perpendicular to the insertion direction, making the cutter 210 flush with or recessed from the end of the insert 200, thus preventing the cutter 210 from being exposed and causing safety hazards. In terms of connection, the cutter 210 is located at one end of the insert 200, and its projection in a plane perpendicular to the insertion direction lies within the plane of the end of the insert 200 closest to the cutter 210.

[0047] In actual use, since the projection of the cutter 210 is located in the end plane of the insert 200, when the insert 200 is inserted into the pull tab seat 100, the cutter 210 is completely contained in the internal space of the pull tab seat 100 and will not be exposed from the side or end face of the pull tab seat 100. When the operator pinches the pull tab seat 100 to pull the zipper, the cutting edge of the cutter 210 will not come into contact with it.

[0048] By limiting the projection of the cutter 210 to the end plane of the insert 200, the zipper pull tab 1100 with a hidden and detachable cutter provided in this application embodiment achieves complete concealment of the cutter 210 during use, avoiding the risk of accidental scratches caused by the exposed cutter 210, improving the safety of use, and ensuring the overall neatness of the pull tab.

[0049] Please continue to refer to Figures 1 to 4 According to some embodiments of this application, such as Figures 1 to 4 As shown, there are two card interfaces 120, which are located on opposite sides of the pull tab holder 100. There are also two card receiving parts, which are configured to correspond one-to-one with the card interfaces 120.

[0050] The two card interfaces 120 and two elastic snap-fit ​​parts 230 are structural designs that enable symmetrical snap-fit ​​fixing of the insert 200 and the pull tab seat 100. The purpose of this design is to ensure even force distribution on the insert 200 and a more stable fixation through symmetrical snap-fit ​​on both sides. In terms of connection, the two card interfaces 120 are located on opposite sides of the pull tab seat 100, and the two elastic snap-fit ​​parts 230 are respectively located on the corresponding sides of the insert 200, corresponding one-to-one with the card interfaces 120.

[0051] In actual use, when the insert 200 is inserted into the pull tab holder 100, the elastic snap-fit ​​parts 230 on both sides extend from the corresponding snap-fit ​​interface 120 at the same time, forming a symmetrical double-point snap-fit. The insert 200 will not deflect or shake in the pull tab holder 100, and the fixed state is stable and reliable.

[0052] By setting two symmetrical card interfaces 120 and two corresponding elastic snap-fit ​​parts 230, the zipper pull tab 1100 with a hidden detachable cutter provided in this application embodiment achieves symmetrical and stable fixation of the insert 200 during use, avoiding the swaying of the insert 200 that may be caused by unilateral snap-fit, and improving the overall structural stability and service life of the pull tab.

[0053] Please continue to refer to Figures 1 to 4 According to some embodiments of this application, such as Figures 1 to 4 As shown, the two sides of the cutter 210 parallel to the insertion direction of the insert 200 are not sharpened, and the edge of the cutter 210 away from the insert 200 is sharpened, and the angle between this edge and the adjacent two sides is not 90°.

[0054] The cutting edge layout of the cutter 210 is a structural design that balances its safety and cutting performance. Its purpose is to achieve a balance between guidance and safety during cutting by sharpening only one end and setting a non-right-angled angle. In terms of connection, the two edges of the cutter 210 parallel to the insertion direction are not sharpened, while the edge furthest from the insert 200 is sharpened, and the angle between this sharpened edge and the adjacent two edges is not 90°.

[0055] In actual use, the operator holds the pull tab seat 100 and places the blade 210 at the end of the insert 200 against the material to be cut. Since the blade edge and the adjacent two side edges form a non-right angle, forming a sharp angle structure, it is easy to penetrate the material and cut along the guide direction, while the un-bladed edges on both sides prevent accidental injury to the fingers during operation.

[0056] By setting the cutter 210 to be sharpened on only one end and at a non-right angle to the adjacent edge, the zipper pull tab 1100 with a hidden and detachable cutter provided in this application embodiment achieves precise guidance and efficient cutting during use. At the same time, the design of not sharpening on both sides ensures operational safety and improves the convenience and reliability of cutting operations.

[0057] Please continue to refer to Figures 1 to 4 and further refer to Figure 5 , Figure 6 and Figure 9 , Figure 5 This is a three-dimensional structural diagram of the self-adhesive zipper provided in the embodiments of this application. Figure 6 This is a three-dimensional structural diagram of the self-adhesive zipper provided in the embodiments of this application. Figure 9 An exploded view of the self-adhesive zipper provided in an embodiment of this application. According to another embodiment of this application, as... Figures 6 to 8As shown, a self-adhesive zipper 1000 is provided, including a zipper body 1200, a panel, and a zipper pull tab 1100 with a hidden removable cutter as described above. The zipper pull tab 1100 with the hidden removable cutter is connected to the zipper body 1200 and is used to pull the zipper body 1200 to open and close. The zipper body 1200 is disposed on the panel.

[0058] The zipper body 1200, the mounting plate, and the zipper pull tab 1100 with a hidden, detachable cutter are the core components of the self-adhesive zipper 1000. The zipper body 1200 is designed to enable opening and closing; the mounting plate supports the zipper body 1200 and provides a base for contact with external objects; the zipper pull tab 1100 with a hidden, detachable cutter is connected to the zipper body 1200 and used to pull the zipper body 1200 to open and close. In terms of connection, the zipper body 1200 is mounted on the mounting plate, and the zipper pull tab is connected to the zipper body 1200.

[0059] In actual use, please refer to Figure 10 , Figure 10 This is a schematic diagram illustrating the use of the self-adhesive zipper provided in the embodiments of this application, as shown below. Figure 10 As shown, the operator attaches the patch to the surface of the object to be sealed or packaged, and opens or closes the zipper by pinching the pull tab seat 100 and pulling the zipper body 1200. When it is necessary to cut the outer material, the insert 200 is pulled out from the pull tab seat 100 and the cutter 210 is used to cut along the guide direction.

[0060] By combining the zipper pull tab 1100 with a hidden detachable cutter with the zipper body 1200 and the patch, the self-adhesive zipper 1000 provided in this application embodiment achieves integrated opening and closing and cutting functions during use. It can complete the sealing and opening operations without additional tools, and has a compact structure and is easy to use.

[0061] In the embodiments of this application, the self-adhesive zipper 1000 provided in the embodiments of this application can be attached to dog food bags, rice bags, any bag containers or soft packaging containers with stitching, and the insert 200 can be pulled out and the cutter 210 can be used to cut an opening at the zipper, so that the dog food bag, rice bag, any bag containers or soft packaging containers with stitching can be opened and closed conveniently.

[0062] It is understood that in some other advanced embodiments of this application, please refer to Figure 7 and Figure 8 , Figure 7 A three-dimensional structural diagram of a zipper pull tab with a hidden, detachable cutter, provided for another embodiment of this application. Figure 8A side view of a zipper pull tab with a concealed, removable cutter, provided as an embodiment of this application, such as... Figure 7 and Figure 8 As shown, the self-adhesive zipper 1000 can be configured as a double-sided zipper structure, with zipper bodies 1200 on both sides of the adhesive plate, and each side connected to a zipper pull tab 1100 with a hidden, detachable cutter, as described above. This allows the zipper body 1200 to be opened and closed by pulling on its respective pull tab on both the inside and outside of the self-adhesive zipper 1000. Alternatively, one side can be connected to a regular zipper pull tab, while the other side is connected to the aforementioned zipper pull tab 1100 with a hidden, detachable cutter. For example, in agricultural greenhouse applications, the operator attaches the self-adhesive zipper 1000 to the plastic film of the greenhouse. Whether inside or outside the greenhouse, the operator can directly pinch the corresponding pull tab seat 100 to pull the zipper body 1200 to open and close it without having to go to the other side. Similarly, when used in dustproof doors, the self-adhesive zipper 1000 can be opened and closed from both inside and outside the door. This double-sided zipper structure ensures single-sided cutting functionality while providing convenient two-way opening and closing, making it particularly suitable for enclosed scenarios where both the inner and outer sides need to be operable, thus enhancing its flexibility and applicability.

[0063] Please continue to refer to Figures 1 to 9 According to some embodiments of this application, such as Figures 1 to 9 As shown, the panel includes a fixing layer 1310, a waterproof layer 1320, and an adhesive layer 1330 stacked in sequence; the zipper body 1200 is disposed between the fixing layer 1310 and the waterproof layer 1320. The fixing layer 1310 has a through slit 1311 for exposing the zipper body 1200, and the waterproof layer 1320 has a guide slit 1321 for guiding the cutting direction of the cutter 210.

[0064] The core structure for achieving layering in the panel includes a fixing layer 1310, a waterproof layer 1320, an adhesive layer 1330, a through seam 1311, and a guide seam 1321. The fixing layer 1310 is designed to support the zipper body 1200, with the through seam 1311 exposing the zipper body 1200. The waterproof layer 1320 provides waterproof protection, with the guide seam 1321 guiding the cutting direction of the cutter 210. The adhesive layer 1330 is designed to adhere to external objects. In terms of connection, the fixing layer 1310, waterproof layer 1320, and adhesive layer 1330 are stacked sequentially, with the zipper body 1200 positioned between the fixing layer 1310 and the waterproof layer 1320.

[0065] In actual use, the zipper body 1200 is exposed through the through-slit 1311 on the fixing layer 1310, allowing the pull tab to be pulled to open and close. When cutting is required, the operator places the cutter 210 at the end of the insert 200 against the starting point of the guide seam 1321 on the waterproof layer 1320 and pulls it along the direction of the guide seam 1321. The cutter 210 cuts through the waterproof layer 1320 and the bonding layer 1330 in sequence, achieving precise cutting.

[0066] By setting the adhesive plate as an overlay structure of a fixing layer 1310, a waterproof layer 1320, and an adhesive layer 1330, and by opening a through seam 1311 and a guide seam 1321 respectively, the self-adhesive zipper 1000 provided in this application embodiment achieves stable support of the zipper body 1200 and precise guiding cutting of the cutter 210 during use. The guide seam 1321 effectively limits the offset of the cutter 210, ensuring the accuracy and neatness of the cutting path, and improving the reliability and cutting quality of use.

[0067] Please continue to refer to Figures 1 to 9 According to some embodiments of this application, such as Figures 1 to 9 As shown, the waterproof layer 1320 is made of polyethylene material.

[0068] The waterproof layer 1320, made of polyethylene, is a key material chosen for its waterproof performance. Its purpose is to utilize the excellent waterproof, moisture-proof, and flexible properties of polyethylene to provide a reliable waterproof barrier for the panel. In terms of connection, the waterproof layer 1320, also made of polyethylene, is overlapped between the fixing layer 1310 and the bonding layer 1330.

[0069] In actual use, the waterproof layer 1320 made of polyethylene material can effectively block water penetration and protect the zipper body 1200 and the bonding layer 1330 from the influence of humid environment. At the same time, its flexibility allows the bonding plate to adapt to the deformation of different bonding surfaces and maintain the tightness of the bonding.

[0070] By using polyethylene material for the waterproof layer 1320, the self-adhesive zipper 1000 provided in this application embodiment achieves reliable waterproof isolation of the plate in humid or wet environments, extends the service life of the self-adhesive zipper 1000, and improves its applicability in complex environments such as outdoors and cold chain.

[0071] Please continue to refer to Figures 1 to 9 According to some embodiments of this application, such as Figures 1 to 9 As shown, adhesive backing is provided on the bonding layer 1330.

[0072] The adhesive backing is a component of the bonding layer 1330 that enables self-adhesion. Its purpose is to allow the panel to be directly adhered to the surface of the object to be sealed or packaged without the need for additional fixing tools. In terms of connection, the adhesive backing is located on the bonding layer 1330, specifically on the side of the bonding layer 1330 furthest from the waterproof layer 1320.

[0073] In actual use, the operator peels off the protective film of the adhesive backing, attaches the adhesive layer 1330 to the surface of the object and applies pressure, and the adhesive backing forms a firm bond with the surface of the object, thus fixing the self-adhesive zipper 1000 to the object as a whole.

[0074] By providing adhesive backing on the bonding layer 1330, the self-adhesive zipper 1000 provided in this application embodiment can be quickly and easily glued and fixed without tools during use, making the operation simple. Moreover, the adhesive backing can adapt to various material surfaces, improving the versatility and installation efficiency of the self-adhesive zipper 1000.
