[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] The core of the present invention is to provide an injection-molded glue-dropping pull tab. By setting a cavity in the pull tab, different colored or shaped filling components can be filled in the cavity according to requirements, thereby increasing the recognition rate of the pull tab. Moreover, since it is inside the pull tab, there is no problem of wear and no edges or grooves on the surface of the pull tab.

[0047] Another core of the present invention is to provide a zipper assembly including the above injection-molded glue-dropping pull tab, which has the same technical features and can achieve the same purpose.

[0048] Please refer to Figures 1 - 5 , an injection-molded glue-dropping pull tab, comprising:

[0049] Pull tab body 1;

[0050] Pull tab connecting piece 2, one end of which is hinged to the pull tab body 1;

[0051] Pull tab 3, which is a mirror-transparent injection-molded part, is injection-molded with the other end of the pull tab connecting piece 2, and the pull tab 3 wraps the connecting hole 201; the pull tab 3 is provided with a cavity 301;

[0052] Filling component 4, filled in the cavity 301;

[0053] When producing this product, an integrated injection-molding method is adopted to fixedly connect the pull tab connecting piece 2 and the pull tab 3 to ensure their integrity. At the same time, a mirror-transparent injection-molded part is used as the pull tab 3, which has high transparency and surface smoothness, facilitating the observation of the filling component 4 in the internal cavity 301. Then, by changing the color and / or shape of the filling component 4, the overall recognition rate of the pull tab is improved. Moreover, the filling component 4 is wrapped by the pull tab 3 made of a mirror-transparent injection-molded part, which helps to reduce the wear of the filling component 4 itself and slow down the fading speed of its surface color, enabling it to maintain its recognition rate for a long time. And the surface of the mirror-transparent injection-molded part has good flatness and no grooves, avoiding the situation of dirt accumulation;

[0054] In some embodiments, when designing the internal cavity 301 of the pull tab 3, the internal cavity 301 can be reserved by means of the reserved injection mold of the pull tab 3. However, the form of the cavity 301 in this method is restricted by the shape of the mold, and due to the high cost of mold production, the structure of the internal cavity 301 of the pull tab 3 produced in this embodiment is relatively single. Before or after the filling component 4 is filled, it is necessary to drip glue into the cavity 301 to fill the remaining cavity of the filling component 4, so that the filling component 4 can be stably and firmly fixed in the cavity 301, preventing the filling component 4 from falling, and the transition at the joint between the filling component 4 and the cavity 301 is natural without obvious connection marks;

[0055] In some embodiments, such as Figure 6 and Figure 7 , the cavity 301 is produced by the core-pulling method of the core-pulling rod 5 made of alloy material, that is, core-pulling rods 5 of different shapes are reserved in the injection mold of the pull tab 3. After the pull tab 3 is injection-molded, the core-pulling rod 5 is taken out, and a cavity 301 with the same shape as the core-pulling rod 5 is left in the pull tab 3. The production cost of the core-pulling rod 5 is low and it can be recycled. Therefore, according to the needs, core-pulling rods 5 of different shapes can be designed, and then pull tabs 3 with different-shaped cavities 301 can be produced, such as being designed into aesthetic shapes such as arrow shapes, circular shapes, moons, stars, etc. At the same time, the filling component 4 can also be designed adaptively and filled and fixed by dripping glue, thereby improving the overall recognition and aesthetic feeling of the pull head.

[0056] In some embodiments, a glue dripping port 302 is provided on the side wall surface or the bottom end of the pull tab 3, and the glue dripping port 302 communicates with the cavity 301 for dripping glue into the cavity 301;

[0057] After the filling component 4 is filled, since the shapes of the filling component 4 and the cavity 301 do not completely fit, glue is dripped into the cavity 301 through the glue dripping port 302 to fill the remaining space in the cavity 301, so that the filling component 4 can be fixed in the cavity 301, preventing the filling component 4 from shaking inside the cavity 301 or falling off from the cavity 301, and eliminating the transition seam between the filling component 4 and the inner wall of the cavity 301, making the filling component 4 have better visibility and enhancing its three-dimensional sense and recognition.

[0058] In some embodiments, the glue dripping port 302 is a conical structure, its small-diameter end communicates with the cavity 301, and the surface of the inner wall of the cavity 301 communicating with the glue dripping port 302 is a plane perpendicular to the center line of the glue dripping port 302;

[0059] Through the structural design of the glue dripping port 302, it is convenient to drip glue into the cavity 301 from the outside, and it is avoided that the glue overflows from the glue dripping port 302 during the glue dripping process;

[0060] Among them, the structure of the glue dripping port 302 is made according to the structural shape design of the core-pulling rod 5. As Figure 6 shown, a frustum-shaped tail vertebra is provided at the bottom end of the cylindrical core-pulling rod 5, and the small-diameter end of the tail vertebra is connected to the end of the core-pulling rod 5. When injecting the pulling piece 3, as Figure 7 shown, the injection molded part wraps the core-pulling rod 5, leaving only the lower end of the tail vertebra exposed. After the core-pulling rod 5 is taken out of the injection molded part, a conical structure with an anti-backflow inclined surface will be formed at the glue dripping port 302 of the cavity 301.

[0061] In some embodiments, several groups of independent and non-connected cavities 301 are provided in the pulling piece 3, and each group of cavities 301 is connected with an independent glue dripping port 302;

[0062] When designing the pulling piece 3, some use a single cavity 301 and fill it with a filling component 4, while some use a design with multiple groups of dispersed cavities 301, and each group of cavities 301 is filled independently, so that the pulling piece 3 has different aesthetics and designs, further enhancing its recognition.

[0063] In some embodiments, several groups of interconnected cavities 301 are provided in the pulling piece 3, and at least one group of cavities 301 is connected with a glue dripping port 302;

[0064] In some implementations, a form of series connection of multiple groups of cavities 301 is adopted, and a flowable filling component 4, such as small particles like filling beads and sequins, is filled inside, and it flows and fills each cavity 301 by itself. Then, glue dripping operation is carried out to fix it in the corresponding position, endowing it with different aesthetics and designs, further enhancing its recognition.

[0065] In some embodiments, the pulling piece 3 is flat;

[0066] The maximum length of the cavity 301 is H1, and the length of the pulling piece 3 is H2,

[0067] ;

[0068] The maximum width of the cavity 301 is L1, and the width of the pulling piece 3 is L2,

[0069] ;

[0070] In some other embodiments, the pulling piece 3 is cylindrical, the cavity 301 is a cylindrical cavity, and the glue dripping port 302 is arranged at the bottom end of the pulling piece 3;

[0071] The maximum length of the cavity 301 is H1, and the length of the pulling piece 3 is H2,

[0072] ;

[0073] The inner diameter of the cavity 301 is D1, and the outer diameter of the pull tab 3 is D2.

[0074] ;

[0075] In different application scenarios, the pull tab 3 can be designed into different shapes. For example, if it is designed into a long and flat shape, it is convenient to grip, while if it is designed into a cylindrical shape, it has a stronger three-dimensional sense.

[0076] At the same time, when designing the size of the cavity 301, designing according to the above-mentioned length can leave a larger position for the pull tab connecting piece 2, ensure that the pull tab connecting piece 2 is firmly connected to the pull tab 3, and there is a larger filling space in the cavity 301, so as to facilitate the filling of the filling component 4.

[0077] Designing according to the above-mentioned width and inner diameter, after the filling component 4 is filled, it has a better visual effect, the finished product is more transparent, and it does not affect the bonding strength between the filling component 4 and the pull tab 3.

[0078] In some embodiments, a connecting hole 201 is provided at one end of the pull tab connecting piece 2 where it is connected to the pull tab 3, and the pull tab 3 wraps the connecting hole 201.

[0079] The surface of the part of the pull tab connecting piece 2 wrapped by the pull tab 3 is provided with friction lines.

[0080] By adding the connecting hole 201 at the end of the pull tab connecting piece 2 and adding friction lines on the surface, it is to improve the integrity of the pull tab connecting piece 2 and the pull tab 3, that is, during injection molding, there is a larger contact area between the pull tab 3 and the pull tab connecting piece 2, and the injection molding colloid can penetrate through the connecting hole 201, so that the pull tab 3 can be more firmly connected to the pull tab connecting piece 2.

[0081] In addition to the injection-molded and drip-glued pull tabs disclosed in the above various embodiments, the present invention also provides a zipper assembly including the above injection-molded and drip-glued pull tabs. For the structures of other parts of this zipper assembly, please refer to the prior art and will not be elaborated herein.

[0082] In this specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same and similar parts between the various embodiments, reference can be made to each other.

[0083] The above has introduced in detail the injection-moldable drip-glue pull head and zipper assembly provided by the present utility model. Specific examples are used herein to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
