Abstract
Description
Technical Field
[0001] This utility model relates to the field of clothing technology, and more specifically, to a thermoplastic pendant clock. Furthermore, this utility model also relates to an garment comprising the aforementioned thermoplastic pendant clock. Background Technology
[0002] As a garment accessory, the hanging bell, with its unique shape and vibrant colors, brings a distinctive visual effect to clothing. It is typically sewn onto the collar, cuffs, and hem of garments to enhance their layering and three-dimensionality. Therefore, there is a significant market demand for hanging bells with unique shapes and colors. Besides its decorative function, the hanging bell can also enhance the functionality of clothing to some extent, such as securing the end of a hanging cord.
[0003] Existing pendant lights, used as clothing accessories, require unique designs and vibrant colors to serve as visual embellishments and enhance the three-dimensional effect. In the production process, pad printing and water transfer printing are generally chosen as surface treatment processes for bright styles. However, the colorfastness of pad printing and water transfer printing varies depending on the material of the pendant light itself, leading to fading over long-term use, affecting the overall aesthetics and brand image. Furthermore, pad printing cannot be applied to irregular, uneven surfaces, making it difficult and costly, and the ink used in the process poses a significant health risk. Water transfer printing, on the other hand, requires the pattern film to float on water before being immersed in the pendant light to adhere the film to its surface, a process that is also quite challenging.
[0004] In conclusion, how to solve the problems of high processing difficulty, high cost and easy fading of external printing patterns on bells of different specifications is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a thermoplastic pendant clock by printing the desired pattern on the surface of a heat-shrinkable film, and then heat-shrinking the film to wrap the outer surface of the pendant clock, thereby solving the problems of difficult and costly external printing and dyeing of pendant clocks of different specifications and easy fading.
[0006] Another objective of this invention is to provide a garment that includes the aforementioned thermoplastic bell, possessing the same technical features and capable of solving the same technical problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0020] A garment comprising the thermoplastic pendant bell described in any of the preceding claims.
[0021] The thermoplastic pendant bell provided by this utility model has at least the following advantages compared with the prior art:
[0022] 1. By printing the logo on the surface of the plastic seal film, its color fastness is improved, and it is prevented from peeling off after long-term use. At the same time, the plastic seal film is a heat shrink film, which has a relatively flat surface before heat shrinking, making it easy to transfer or water transfer printing, thereby helping to reduce printing difficulty and cost.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] The core of this utility model is to provide a thermoplastic pendant clock by printing the desired pattern on the surface of a heat-shrinkable film, and then heat-shrinking the film to wrap the outer surface of the pendant clock, thereby solving the problems of difficult and costly external printing and dyeing of pendant clocks of different specifications and easy fading.
[0034] Another core aspect of this utility model is to provide a garment that includes the aforementioned thermoplastic bell, possessing the same technical features and capable of solving the same technical problems.
[0035] Please refer to Figure 1 and Figure 2 A thermoplastic hanging bell, comprising:
[0036] Bell body 2;
[0037] Plastic sealing film 1, which is a heat shrink film, is wrapped around the outer surface of the bell body 2 in a heat shrink form. The outer surface of plastic sealing film 1 is used for marking and printing.
[0038] The part of the outer surface of the bell body 2 that is not covered by the plastic film 1 is provided with a connecting mechanism for installing the connecting parts 3.
[0039] like Figure 1 and Figure 2 As shown, the pendant clock includes a pendant clock body 2 and a plastic sealing film 1. The pendant clock body 2 is used to connect with the connecting component 3, while the plastic sealing film 1 is used to carry the printed logo. In use, the plastic sealing film 1 is wrapped around the outside of the pendant clock body 2. Since the plastic sealing film 1 is made of heat shrink film, heating the plastic sealing film 1 can make it firmly wrapped around the pendant clock body 2. Due to the inherent characteristics of the plastic sealing film 1, it has a relatively flat surface before heat shrinking, which helps to print the logo on its surface. In addition, combined with the inherent characteristics of the plastic sealing film 1, its surface has high color fastness, and the probability of the pattern wearing off after long-term use is small, which helps to improve the product quality of the pendant clock.
[0040] Meanwhile, the heat-shrinkable film 1 can adapt to the shape of the bell body 2 when it is heat-shrinked, thus making close contact with the surface of the bell body 2. Therefore, for the bell body 2 with irregular uneven surfaces, using heat-shrinkable film 1 to wrap it can effectively reduce processing costs and ensure the fit of the film 1, thereby improving the sealing effect.
[0041] In some embodiments, the exterior of the bell body 2 is coated with powder and then heated to achieve a rubber coating on the outer surface of the bell body 2. That is, a rubber layer is produced on the outer surface of the bell body 2, which can also improve the appearance of the bell and enhance the color fastness of the surface markings. However, it is still not suitable for low melting point materials such as plastics. Furthermore, for bell bodies 2 with irregular surfaces, it is difficult to print markings after the rubber coating. Therefore, it is suitable for bell bodies 2 with high melting point materials and regular surfaces.
[0042] In some embodiments, the bell body 2 is made using an impregnation process to form an adhesive layer on the surface, which can improve the appearance of the bell and enhance the color fastness of the surface markings. This is suitable for the use of irregular bell bodies 2. However, it is still not suitable for low-melting-point materials such as plastics. Furthermore, for bell bodies 2 with irregular surfaces, it is difficult to print markings after the coating. Therefore, it is suitable for bell bodies 2 with high melting points and regular surfaces. Moreover, the plastic sealant 1 of both impregnation and coating methods may peel off, affecting the service life of the bell.
[0043] In some embodiments, the plastic sealant 1 has a cylindrical structure, and the inner cross-sectional area of the plastic sealant 1 before heat shrinking is larger than the outer cross-sectional area of the bell body 2 at the corresponding position.
[0044] like Figure 2 As shown, the plastic wrap 1 has a cylindrical structure that can directly wrap the bell body 2. The overall cross-section is annular. When it is heat-shrinked, the internal tension of the shrinkage will cause the heat-shrink film to be firmly attached to the outer surface of the bell body 2. The inner cross-sectional area of the plastic wrap 1 before heat shrinkage is larger than the outer cross-sectional area of the bell body 2, which makes it easier to place the bell body 2 inside the plastic wrap 1 for sealing and reduces the difficulty of sealing.
[0045] In some embodiments, the area of the outer surface of the bell body 2 covered by the plastic sealant 1 is 0.5-0.6 times the area of the corresponding position on the inner surface of the plastic sealant 1.
[0046] By limiting the ratio of the plastic sealing area of the bell body 2 to the effective area of the plastic sealing film 1, the plastic sealing film 1 shrinks by 50%-60% during thermoplastic deformation, thereby avoiding distortion of the surface pattern of the plastic sealing film 1.
[0047] In some embodiments, the length of the heat-shrinkable plastic sealant 1 along its own axial direction is not less than the length of the bell body 2 along its own axial direction.
[0048] like Figure 1 As shown, the axial length of the plastic sealant 1 is greater than the axial length of the bell body 2. Therefore, during plastic sealing, in addition to the outer peripheral surface of the bell body 2 being sealed, the end portion of the bell body 2 can also be sealed. This results in an overlap between the end of the plastic sealant 1 and the end of the bell body 2, which suppresses the axial relative movement between the plastic sealant 1 and the bell body 2, thus ensuring the axial relative position stability of the plastic sealant 1 and the bell body 2.
[0049] In some embodiments, the molding film 1 is a semi-transparent PET film.
[0050] The plastic seal 1 is made of PET material, which has high color fastness and the pattern is not easy to peel off. The semi-transparent material can partially highlight the material characteristics of the bell body 2 and improve the quality of the bell. At the same time, after printing the semi-transparent plastic seal 1, it is heat-shrinked onto the outer surface of the bell body 2, which can achieve 360° pattern coverage on the bell's exterior and reduce the problem of printing offset.
[0051] In some embodiments, the sealing film 1 is a tubular thermoplastic film with no seams on the sidewalls.
[0052] The tubular plastic sealant 1 is produced by integral extrusion or stretching, so there are no seams on its outer wall. Therefore, when the plastic sealant 1 is heat-shrinked, there is no obvious tangential stress, which reduces stress concentration in the plastic sealant 1 and prevents damage. It can also fit snugly to the outer surface of the bell body 2.
[0053] In some embodiments, the outer surface of the molding film 1 is a non-mirror structure.
[0054] The outer periphery of the plastic sealant 1 has a frosted surface structure, which allows for a larger surface area during printing and dyeing, thereby increasing the amount and strength of ink adhesion and further improving the color fastness of the surface pattern.
[0055] In some embodiments, the connecting mechanism includes a connecting hole 21 that extends through the axial direction of the bell body 2, and both ends of the connecting hole 21 are located in the area on the outer surface of the bell body 2 that is not covered by the plastic sealant 1.
[0056] like Figure 3 and Figure 4 As shown, the connecting mechanism is an axially penetrating connecting hole 21. When using a rope-structured connecting component 3, the connecting component 3 can pass directly through the connecting hole 21 and be knotted at the end to prevent the connecting component 3 from passing through in the opposite direction, thereby completing the connection between the bell body 2 and the connecting component 3.
[0057] In some embodiments, the connecting hole 21 is a stepped hole. The rope structure enters from the small diameter end of the connecting hole 21 and exits from the large diameter end of the connecting hole 21. After the exiting end is knotted, the rope structure is pulled back so that the knot enters the large diameter portion of the connecting hole 21. Thus, during the sealing process, the sealing film 1 can seal the large diameter end opening of the connecting hole 21 together.
[0058] In some embodiments, the length of the plastic sealant 1 is increased so that the entire bell body 1 is wrapped, and the part of the rope structure near the end of the bell body 2 is also wrapped. In this case, since the inner wall of the plastic sealant 1 can be tightly bonded to the bell body 2 and the rope structure after heat shrinking, the plastic sealant 1 can wrap both ends of the connection hole 21 at the same time, preventing foreign objects from entering and preventing relative movement between the rope structure and the bell body 2.
[0059] In some embodiments, the connecting mechanism is an ear seat located at one end of the bell body 2, with a through hole on the ear seat. The connecting component 3 is a rope, and the end of the rope is tied to the through hole on the ear seat. During plastic sealing, the plastic sealing film 1 covers the entire bell body 2 and the end of the rope, so that after heat shrinking, the plastic sealing film 1 can simultaneously wrap the entire bell body 1 and the end of the rope, thereby wrapping the tied part of the rope end together and preventing the tied part from loosening.
[0060] In some embodiments, the bell body 2 is a cylindrical structure with a small opening at one end, and the outer peripheral wall of the bell body 2 is a hollow structure. The connecting part 3 is a rope that enters from the opening at the small diameter end and exits from the large diameter end. After knotting, it is pulled back so that the knot is inside the bell body 2. At the same time, the plastic seal 1 is a transparent or semi-transparent film. After heat shrinking, the pattern on the outer peripheral surface of the bell body 2 can be directly displayed through the plastic seal.
[0061] Alternatively, the connecting mechanism of the bell body 2 is located at the end, and the outer peripheral surface markings are engraved with concave and convex engravings. The corresponding markings are printed at the corresponding positions on the plastic film 1, so that the three-dimensional display of the pattern on the surface of the plastic film 1 can be achieved after heat shrinking.
[0062] Furthermore, a positioning structure is set on the outer surface of the bell body 2, and a positioning mark is set at the corresponding position of the plastic film 1 for positioning the positioning structure. During assembly, the positioning mark and the positioning structure are combined to position the bell body 2 and the plastic film 1 to ensure that the embossed and printed marks can have the correct relative positional relationship after heat shrinking.
[0063] At the same time, additional auxiliary tooling can be used to position the bell body 2 and the plastic film 1 respectively to ensure that the relative positional relationship between the two is accurate before heat shrinking, so that the markings printed on the surface of the plastic film 1 after heat shrinking can have the correct relative positional relationship with the concave and convex engravings on the outer surface of the bell body 2.
[0064] In some embodiments, the bell body 2 is a columnar or frustum-shaped structure, and the connecting mechanism is a connecting hole 21 that coaxially penetrates the bell body 2. The outer peripheral surface and the end non-connecting hole 21 of the bell body 2 are all wrapped by the plastic sealing film 1.
[0065] like Figure 1 and Figure 2 As shown, the bell body 2 is a cylindrical structure, and a through connection hole 21 is provided at the axis position for the connection component 3 to pass through. Moreover, the area outside the bell body 2 that is not occupied by the connection hole 21 is covered by the plastic film 1, which can expand the printing area of the logo and ensure the stability of the relative positional relationship between the plastic film 1 and the bell body 2.
[0066] In addition to the thermoplastic pendant bells disclosed in the above embodiments, this utility model also provides an garment including the above-mentioned thermoplastic pendant bells. For the structure of other parts of the garment, please refer to the prior art, which will not be repeated here.

The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of this utility model.
