Description

Technical Field

[0001] The utility model specifically relates to a tearable bottle cap. Background Art

[0002] With the increasing awareness of environmental protection among people, reducing the impact of plastic waste on the environment has become a global issue. In the beverage packaging industry, bottle caps, as an important part of plastic waste, their sustainability and recyclability have received more and more attention. For example, for edible liquid bottle products such as soy sauce bottles and cooking wine bottles, the products generally have a cap seat connected to the bottle body, and an opening and closing cover that can be opened or closed relative to it is connected to the cap seat. When in use, the opening and closing cover is opened by flipping to pour out the liquid in the bottle, and when not in use, the opening and closing cover is buckled back to the cap seat for sealing. However, since the cap seat is tightly buckled to the bottle body, when the edible liquid is used up and the edible liquid bottle is recycled, it is difficult to detach the plastic bottle cap from the glass bottle body, which is not convenient for material recycling and classification. At present, the operation of recycling and disassembling plastic bottle caps for edible liquid bottles on the market is inconvenient, the recycling efficiency is low, and the cost is relatively high.

[0003] The present utility model is precisely produced based on the above deficiencies. Summary of the Utility Model

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art and provide a tearable bottle cap that is convenient for separating the opening and closing cover from the cap seat.

[0005] The present utility model is realized through the following technical solutions:

[0006] A tearable bottle cap includes a cap seat for connecting to a bottle body. The cap seat is connected with an opening and closing cover, and the cap seat and the opening and closing cover are connected through a connecting ear. The connecting ear is flexible so that the opening and closing cover can be opened or closed relative to the cap seat. The cap seat includes an annular plate for connecting to the bottle body. A partition groove with a depth set from top to bottom and a length set along the circumferential direction is provided on the annular plate. The partition groove divides the upper half of the annular plate into an inner plate located inside and a tearable plate located outside. The connecting ear is connected to the tearable plate of the cap seat, and a first thin-wall tearing portion with a smaller thickness and vertically arranged is provided on the tearable plate.

[0007] For the tearable bottle cap as described above, the partition groove has a head end and a tail end in the length direction. The distance between the head end and the connecting ear is less than the distance between the tail end and the connecting ear, and the first thin-wall tearing portion is arranged between the head end of the partition groove and the connecting ear.

[0008] For the tearable bottle cap as described above, a second thin-wall tearing portion aligned with the first thin-wall tearing portion is provided on the lower half of the annular plate.

[0009] The tearable bottle cap as described above, wherein the inner side wall of the lower half of the annular plate is provided with a groove, the upper side wall of the groove is located below the lower side wall of the partition groove, and the inner side wall of the groove is located inside the inner side wall of the partition groove.

[0010] For the tearable bottle cap as described above, the distance between the upper side wall of the groove and the lower side wall of the partition groove is H, and 0.15 mm < H < 0.3 mm.

[0011] For the tearable bottle cap as described above, the distance between the inner side wall of the groove and the inner side wall of the partition groove is D, and 0.1 mm < D < 0.2 mm.

[0012] For the tearable bottle cap as described above, the tearable plate is further provided with a third thin-wall tear portion with a smaller thickness and arranged vertically.

[0013] For the tearable bottle cap as described above, the third thin-wall tear portion is arranged between the end of the partition groove and the connecting ear.

[0014] For the tearable bottle cap as described above, the cap base, the connecting ear and the opening / closing cap are an integrally injection-molded integral structure.

[0015] Compared with the prior art, the present utility model has the following advantages:

[0016] 1. The tearable bottle cap of the present utility model is provided with a tearable structure, which is convenient for separating structures such as the opening / closing cap, the connecting ear and the tearable plate from the entire cap base, facilitating recycling and classification;

[0017] 2. The material thickness at the connection point between the lower half of the annular plate and the inner plate of the tearable bottle cap of the present utility model is extremely thin. When the first thin-wall tear portion and the second thin-wall tear portion are torn together, the lower half of the annular plate and the tearable plate can be separated from the inner plate. Such a design can enable the lower half of the annular plate and the tearable plate 113 to be separated from the annular plate. When the opening / closing cap, the connecting ear and the tearable plate are separated from the entire bottle cap, they are separated from the entire bottle cap together with the lower half of the annular plate. Compared with the traditional tearable bottle cap, more materials can be separated, which is beneficial to improving the recycling efficiency;

[0018] 3. The tearable bottle cap of the present utility model is further provided with a third thin-wall tear portion. After the tearable plate is peeled off from the cap base, by tearing the third thin-wall tear portion, it is convenient to tear and separate the structure connecting the opening / closing cap, the connecting ear and the tearable plate 113 as a whole.

[0024] The following further describes the utility model in conjunction with the attached drawings:

[0025] The orientations described in the utility model specification, such as "upper", "lower", "left", "right", "front", "rear", etc., are all based on the orientations of the attached drawings and are for the purpose of facilitating the description of the relationships between various components, rather than indicating the only or absolute positional relationships between various components. It is only one of the implementation manners for realizing the utility model and is not a limitation on its implementation manners.

[0026] This embodiment provides a tearable bottle cap, as Figures 1 to 4 shown. This kind of tearable bottle cap includes a cap base 1 for connecting to the bottle body A. The cap base 1 is connected with an opening and closing cap 2. The cap base 1 and the opening and closing cap 2 are connected through a connecting ear 3. The connecting ear 3 is flexible so that the opening and closing cap 2 can be turned over or closed relative to the cap base 1. The cap base 1 includes an annular plate 11 for connecting to the bottle body A. As Figure 3 shown, the annular plate 11 is arranged in a ring in the circumferential direction. The annular plate 11 is provided with a partition groove 111 with a depth set from top to bottom and a length set along the circumferential direction. As Figure 1 and Figure 2 shown, the partition groove 111 of the annular plate 11 is also arranged in an arc along the circumferential direction. The partition groove 111 divides the upper half of the annular plate 11 into an inner plate 112 located inside and a tearable plate 113 located outside. The connecting ear 3 is connected to the tearable plate 113 of the cap base 1. The tearable plate 113 is provided with a first thin-wall tearing part 114 with a smaller thickness and arranged vertically. The wall thickness of the first thin-wall tearing part 114 is 0.2 mm to 0.4 mm, so as to facilitate tearing the material at the first thin-wall tearing part 114, thereby separating the tearable plate 113 from the inner plate 112, and thus facilitating separating the opening and closing cap 2, the connecting ear 3 and the tearable plate 113 from the entire bottle cap, which is convenient for recycling and classification.

[0027] As a preferred solution, as Figure 1 and Figure 2As shown, the separation groove 111 has a leading end 111a and a trailing end 111b in the length direction. The distance between the leading end 111a and the connecting ear 3 is less than the distance between the trailing end 111b and the connecting ear 3. The first tearing portion is provided between the leading end 111a and the connecting ear 3.

[0028] As Figure 2 and Figure 3 shown, the lower half of the annular plate 11 is provided with a second thin-wall tearing portion 115 aligned with the first thin-wall tearing portion 114. In this way, when the first thin-wall tearing portion 114 is torn, the second thin-wall tearing portion 115 can be torn together, so that this place can be vertically split from top to bottom.

[0029] Preferably, as Figure 4 shown, the inner side wall of the lower half of the annular plate 11 is provided with a groove 116. The upper side wall 116a of the groove 116 is located below the lower side wall 111a of the separation groove 111. The inner side wall 116b of the groove 116 is located inside the inner side wall 111b of the separation groove 111. The distance between the upper side wall of the groove 116 and the lower side wall of the separation groove 111 is H, where 0.15 mm < H < 0.3 mm. The distance between the inner side wall of the groove 116 and the inner side wall of the separation groove 111 is D, where 0.1 mm < D < 0.2 mm. As Figure 4 shown, this makes the material thickness at the connection point P between the lower half of the annular plate 11 and the inner plate 112 extremely thin. When the first thin-wall tearing portion 114 and the second thin-wall tearing portion 115 are torn together, the lower half of the annular plate 11 and the tearable plate 113 can be separated from the inner plate 112. Such a design can separate the lower half of the annular plate 11 and the tearable plate 113 from the annular plate 11. In this way, when the opening / closing lid 2, the connecting ear 3 and the tearable plate 113 are separated from the entire bottle cap, the lower half of the annular plate 11 is also separated from the entire bottle cap. Compared with the traditional tearable bottle cap, more materials can be separated, which is beneficial to improving the recycling efficiency.

[0030] When it is necessary to remove the opening / closing lid 2 for recycling, just pull the opening / closing lid 2 out of the lid seat 1, so that the material at the first thin-wall tearing portion 114 is first torn, and at the same time the second thin-wall tearing portion 115 is torn together. The opening / closing lid 2 and the connecting ear 3 pull the tearable plate 113 to be separated from the lid seat 1, that is, the tearable plate 113 is pulled open from the vicinity of the leading end 111a of the separation groove 111 and is gradually peeled off from the leading end 111a to the trailing end 111b of the separation groove 111. After peeling, the bottle cap is as Figure 5 shown.

[0031] Preferably, as Figure 2As shown, a third thin-wall tearing portion 117 with a smaller thickness and vertically arranged is further provided on the tearable plate 113. The third thin-wall tearing portion 117 is arranged between the end 111b of the partition groove 111 and the connecting ear 3. The wall thicknesses of the second thin-wall tearing portion 115, the third thin-wall tearing portion 117 and the first thin-wall tearing portion 114 are similar, and a wall thickness of about 0.2 mm to 0.4 mm can also be adopted, so as to facilitate tearing the material at this place. In this way, after the tearable plate 113 is peeled off from the cover base 1, by tearing the third thin-wall tearing portion 117, it is further convenient to tear and separate the entire structure connecting the opening and closing cover 2, the connecting ear 3 and the tearable plate 113.

[0032] Preferably, the cover base 1, the connecting ear 3 and the opening and closing cover 2 are an integrally injection-molded integral structure, made of LDPE plastic or PE plastic, and the thickness of the connecting ear 3 is about 0.3 mm to 1.5 mm, so that the connecting ear 3 can be bent and has a certain flexibility.

[0033] The above are only embodiments of the present invention, and common knowledge such as specific structures and characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
