Caps, bottles, merchandise

Abstract

This utility model provides a rubber cap, bottle, and product, including a cap body and a cut on the cap body. The cut is a dotted line cut, with one cut length A, and the uncut gap length B between two cuts. The ratio of adjacent cuts to gaps, A:B, ranges from 1:1 to 1:4. This utility model's cap cut ensures that the cap will not easily burst open when shrinking, greatly improving production efficiency and preventing large-scale waste caused by the cap bursting during shrinkage. It also makes the holes created by the shrinkage of the cut more uniform and smaller, making the difference in hole diameter difficult to discern with the human eye, thus enhancing the aesthetics of the cap.

Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a plastic cap, a bottle, and a product. Background Technology

[0002] With the rapid development of the market economy and the increasing demands of consumers for product quality and safety, plastic caps are commonly used to seal the packaging of products in the wine, food, and pharmaceutical industries. Plastic caps, as a common bottle-shaped packaging sealing structure made of plastic film, are widely used due to their non-toxic, non-polluting, good sealing, and preservation properties. However, when the plastic cap is placed at the bottle opening, it can be extremely inconvenient for consumers to open. To facilitate opening, manufacturers typically add slits to the plastic cap during the manufacturing process.

[0003] However, the cut on the cap is extremely prone to bursting open when it shrinks to the bottle opening, which greatly reduces production efficiency. At the same time, the burst cap cannot be used, resulting in material waste.

[0004] While some caps did not burst open during shrinkage, the cut lines created irregularly shaped holes, significantly affecting their appearance. For example, the invisible micropores described in patent CN 213650527 U have a length of 0.7-0.8 mm and a spacing of 0.3-0.4 mm. During heat shrinkage, uneven heating in various directions results in holes with significant visual size deviations, far exceeding the minimum resolution of the human eye, severely impacting the appearance. Utility Model Content

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a cap, bottle, or product.

[0006] A rubber cap provided according to this utility model.

[0007] The cap includes a cap body and a cap cutout on the cap body.

[0008] The number of slits in the cap is at least one.

[0009] When the number of cuts in the cap is greater than one, the cuts in the cap are parallel or intersecting, or partially parallel and / or partially intersecting, or completely non-parallel and completely non-intersecting.

[0010] The cut on the cap can be straight or curved.

[0011] The cut of the cap is a dotted line cut. The length of one cut of the dotted line cut is A, the length of the gap between two cuts that are not cut is B, and the cutting ratio of the dotted line cut A:B ranges from 1:1 to 1:4.

[0012] The length of a single cut is in the range of 0.1mm ≤ A ≤ 0.6mm.

[0013] Preferably, in areas with printed patterns, the ratio A:B of the dotted line cuts ranges from 1:1 to 1:2.

[0014] The length of a single cut is within the range of 0.15mm ≤ A ≤ 0.3mm.

[0015] The ratio of A to B in the same dashed line cut or different dashed line cuts may be the same or different.

[0016] When the number of slits in the cap is greater than one, the spacing between different cap slits may be equal or unequal.

[0017] The distance between the cut of the cap and the closest point on the top section of the cap body and the bottom section of the cap body is H1. The height of the cap body is H. The value of H1 is in the range of H1≤70%H.

[0018] The end of the cut of the cap is connected to an easy-pull strap, or has an easy-pull opening.

[0019] The cap has no seams.

[0020] According to the present invention, a bottle includes a bottle body and a cap that prevents shrinkage and bursting, the cap being connected to the bottle mouth and the bottle cap of the bottle body.

[0021] According to the present invention, a product includes a product body and a cap that prevents shrinkage and bursting, the cap being connected to the sealing portion of the product body.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The present invention proposes a cap with a slit on the cap body, which ensures that the cap will not easily burst open when it shrinks, greatly improving the production efficiency reduced by the bursting of the cap during shrinkage and preventing large-scale waste. At the same time, it can also make the holes produced by the shrinkage of the slit more uniform and smaller, making it difficult for the human eye to distinguish the error between the hole diameters, thereby improving the aesthetics of the cap. Attached Figure Description

[0024] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0025] Figure 1 This is a schematic diagram of the cutout of the cap according to one embodiment of the present invention;

[0026] Figure 2 This is a schematic diagram of the cutout of the cap according to another embodiment of the present invention. Detailed Implementation

[0027] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0028] Example 1

[0029] like Figure 1 As shown in the illustration, this embodiment provides a cap that prevents it from bursting open during shrinkage, comprising: a cap body 1 and a cap slit 2 on the cap body. The cap slit 2 is a cutting edge structure provided on the cap body 1 for convenient opening of the cap or for other functions. In this invention, the cap slit is a dotted line slit, with the length of one cut of the dotted line slit being A, the length of the uncut gap between two cuts being B, and the cutting ratio A:B of the dotted line slit ranging from 1:1 to 1:4. The length of one cut A ranges from 0.1mm ≤ A ≤ 0.6mm. This design of the cap slit 2 ensures that the cap will not easily burst open when shrinking, greatly improving production efficiency reduced by the bursting of the shrinking cap. The cap slit 2 can be a straight line, and the number of cap slits 2 can be one, two, or more; this invention does not limit this. In this embodiment, the cap body 1 can be seamless. If the cap body 1 is cut open with a knife and the cap is transferred to a counterfeit product for reuse, it can be determined by visually observing whether there are knife marks, thus increasing the difficulty of transferring and reusing the cap.

[0030] Since the shrinking of the cap relies on the heating of the area above the cap shrinking device, to ensure the overall shrinking effect, the upper part of the cap experiences a higher temperature than the lower part inside the shrinking device. When the cap cut is located in the upper part of the cap, the shrinkage hole will be more obvious, the visual deviation will be greater, and it will be more prone to bursting during shrinkage. Figure 2 As shown, the distance between the cut of the cap and the closest point on the top section of the cap body and the bottom section of the cap body is H1, and the height of the cap body is H. The value of H1 is in the range of H1≤70%H, which can further prevent the cap from bursting open when shrinking.

[0031] The cut-to-connection ratio A:B at different locations along the same dashed line can be the same or different. For example, in some embodiments, the cap body 1 is a solid color cap body or the area where the cap cut 2 is located is a solid color area; in this case, the cut-to-connection ratio A:B of the dashed line cut can be the same. For example... Figure 1 As shown, in some embodiments, the cut 2 of the cap is simultaneously located in both the unprinted pattern area 11 and the printed pattern area 12 of the cap body 1. The printed pattern can be a trademark, anti-counterfeiting pattern, etc. In the printed pattern area 12, due to uneven heating in various directions when the cap shrinks, holes with large visual size deviations will be formed, affecting the pattern effect and overall aesthetics. By using a smaller cutting ratio, the holes can be made more uniform and smaller, making it difficult for the human eye to distinguish the error between the hole diameters, and the pattern is more aesthetically pleasing. Therefore, the cutting ratio A:B in the printed pattern area 12 is designed to be in the range of 1:1 to 1:2, and the length of a cut length A is in the range of 0.15mm≤A≤0.3mm.

[0032] In some embodiments, when the number of cap slits 2 is greater than one, the cap slits 2 can be parallel or intersecting each other. Simultaneously, the spacing between two adjacent cap slits 2 can be equal or unequal, provided that the distance H1 between the nearest point of the cap slit to the upper end of the cap body and the lower end of the cap body satisfies H1 ≤ 70%H. When the number of dashed line slits is greater than one, the connection ratio A:B between different dashed line slits can be the same or different.

[0033] To facilitate opening the cap from the end of the cut 2, a pull strap or a pull opening can be provided at the end of the cut. Users can quickly open the cap by simply pulling the pull strap or the pull opening.

[0034] Example 2

[0035] like Figure 2 As shown in the figure, this embodiment provides a cap that prevents it from bursting open during shrinkage, comprising: a cap body 1 and a cap slit 2 on the cap body. The cap slit 2 is a cutting edge structure provided on the cap body 1 for convenient opening of the cap or for other functions. In this utility model, the cap slit is a dotted line slit, the length of one cut of the dotted line slit is A, the length of the uncut gap between two cuts is B, the cutting ratio A:B of the dotted line slit ranges from 1:1 to 1:4, and the length of one cut A ranges from 0.1mm ≤ A ≤ 0.6mm. The cap slit 2 designed in this way can ensure that the cap will not easily burst open when shrinking, greatly improving the production efficiency reduced by the bursting of the shrinking cap. The cap slit 2 can be a straight line or a curve, and the number of cap slits 2 can be one, two, or more; this utility model does not limit this.

[0036] In this embodiment, the dashed cut is a curve, and the distance between the cut of the cap and the closest point of the top section of the cap body and the bottom section of the cap body is H1. The height of the cap body is H, and the value range of H1 is H1≤70%H, which can further prevent the cap from bursting when shrinking.

[0037] In some embodiments, when the number of cap slits 2 is greater than one, the cap slits 2 can be partially parallel and / or partially intersecting, or they can be completely non-parallel and completely non-intersecting. Meanwhile, the spacing between two adjacent cap slits 2 can be equal or unequal, as long as the distance H1 between the nearest point of the cap slit to the upper end of the cap body and the lower end of the cap body satisfies H1 ≤ 70%H. When the number of dashed line slits is greater than one, the connection ratio A:B between different dashed line slits can be the same or different.

[0038] Example 3

[0039] This utility model also provides a bottle, including a bottle body and a shrink-proof cap as described in Embodiment 1. The shrink-proof cap is connected to the bottle mouth and the bottle cap of the bottle body. The cap is heat-shrinked by a shrink-proof device to seal the bottle mouth and the bottle cap. The user can open the cap by tearing open the cap slit 2 on the cap, thereby opening the bottle cap.

[0040] The shrink-proof cap of Example 1 can also be applied to any other product that needs to be sealed. The shrink-proof cap is attached to the sealing part of the product body and the cap is heat-shrinked by a shrink device.
