Description

Technical Field

[0001] The utility model relates to the technical field of beverage packaging, in particular to a wire-free implosion cover. Background Art

[0002] Bottle caps are a crucial component of food and beverage packaging, serving as the first point of contact for consumers. They maintain a tight seal around the contents, while also providing tamper-evident protection and enhanced safety. Consequently, they are widely used in bottled products. As an upstream industry for the food, beverage, alcohol, chemical, and pharmaceutical industries, they are a key component of bottle container packaging.

[0003] At present, the implosion cover is prone to produce material threads and powder. For example, in the patent with publication number CN215795611U, when the anti-counterfeiting edge of the inner cover enters the inverted position of the upper side of the anti-counterfeiting ring, both the inner cover and the anti-counterfeiting ring are easily scratched to form powder. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a thread-free implosion cap. By arranging an elastically shrinkable anti-counterfeiting ring, the anti-counterfeiting ring is directly sleeved on the outer wall of the inner cap during the assembly of the bottle cap. During the assembly process of the bottle cap, the anti-counterfeiting ring will not be forcibly interfered with any component of the bottle cap, thereby reducing the risk of thread appearing during the assembly and opening of the bottle cap; at the same time, when the bottle cap is opened and screwed back, the anti-counterfeiting ring is surface-to-surface fitted between the inner cap and the component, and there is no risk of the inner cap being reset by screwing back.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] A wire-free implosion cover comprises an inner cover, an assembly, and a lower sleeve. The inner cover is arranged on the upper part of the assembly, and the lower sleeve is arranged on the lower part of the assembly. The cover also comprises an anti-counterfeiting ring, which is coaxially sleeved outside the bottom of the inner cover. The upper end of the lower sleeve is formed with an inward fold, and the fold is pressed against the anti-counterfeiting ring to limit the axial displacement of the anti-counterfeiting ring.

[0007] When the inner cover moves upward, the anti-counterfeiting ring is separated from the inner cover, and after separation, the anti-counterfeiting ring shrinks radially until the inner diameter of the anti-counterfeiting ring is smaller than the outer diameter of the inner cover.

[0008] Furthermore, the anti-counterfeiting ring is an elastic open ring.

[0009] Furthermore, the anti-counterfeiting ring is a retaining spring.

[0010] Furthermore, a gap is provided between the folded edge and the outer wall of the inner cover.

[0011] Furthermore, a display ring is coaxially provided on the upper end of the anti-counterfeiting ring, and the display ring extends from the gap to the upper end of the lower sleeve.

[0012] Furthermore, the display ring and the anti-counterfeiting ring are an integrated structure.

[0013] The beneficial effects of the utility model are:

[0014] The bottle cap of the utility model is provided with an elastically shrinkable anti-counterfeiting ring, which is directly sleeved on the outer wall of the inner cap during assembly of the bottle cap. During the assembly process of the bottle cap, the anti-counterfeiting ring will not be forcibly interfered with any component of the bottle cap, thereby reducing the risk of material threads appearing during assembly and opening of the bottle cap; at the same time, when the bottle cap is opened and screwed back, the anti-counterfeiting ring is surface-to-surface fitted between the inner cap and the component, and there is no risk of the inner cap being reset by screwing back.

[0019] The following will be combined with the embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0020] See Figure 1-Figure 3 , the utility model provides a technical solution:

[0021] Example 1:

[0022] like Figure 1-Figure 3 As shown, a wire-free implosion cover comprises an inner cover 1, an assembly 2 and a lower sleeve 3. The inner cover 1 is arranged on the upper part of the assembly 2, and the lower sleeve 3 is arranged on the lower part of the assembly 2. The cover also comprises an anti-counterfeiting ring 4, which is coaxially sleeved outside the bottom of the inner cover 1. The upper end of the lower sleeve 3 is formed with an inward fold, and the fold is pressed against the anti-counterfeiting ring 4 to limit the axial displacement of the anti-counterfeiting ring 4.

[0023] When the inner cover 1 moves upward, the anti-counterfeiting ring 4 separates from the inner cover 1 , and after separation, the anti-counterfeiting ring 4 shrinks radially until the inner diameter of the anti-counterfeiting ring 4 is smaller than the outer diameter of the inner cover 1 .

[0024] The anti-counterfeiting ring 4 is an elastic opening ring.

[0025] The anti-counterfeiting ring 4 is a retaining spring.

[0026] A gap is provided between the folded edge and the outer wall of the inner cover 1. The gap is slightly wider than the width of the latch on the outer wall of the inner cover 1. This prevents the latch from interfering with the assembly of the lower housing 3 during assembly, making assembly smoother. The latch is used to connect the inner cover 1 (snap-lock) to the outer cover.

[0027] Among them, component 2 is existing technology, and the specific structure is not described here.

[0028] Working principle: Bottle cap assembly: The inner cap 1 is threadedly connected to the upper part of the component 2, and then the anti-counterfeiting ring 4 is put on the outside of the inner cap 1 (in this process, the anti-counterfeiting ring 4 expands), and the bottom of the anti-counterfeiting ring 4 abuts against the step surface of the component 2. Then assemble the lower sleeve 3, and the lower sleeve 3 is put from the upper end of the inner cap 1 from top to bottom until the lower sleeve 3 is snapped into contact with the component 2. When the lower sleeve 3 is snapped into contact with the component 2, the folded edge of the lower sleeve 3 is pressed tightly against the top of the anti-counterfeiting ring 4. At this time, the axial displacement of the anti-counterfeiting ring 4 is limited by the component 2 and the folded edge. Finally, press down the outer cap to snap into contact with the inner cap 1. The assembly of the bottle cap as a whole and the bottle mouth is a prior art and will not be described here.

[0029] When the bottle cap is opened, the outer cap rotates, driving the inner cap 1 upward. Because the anti-counterfeiting ring 4 is axially restrained by the folded edge, the inner cap 1 separates from the anti-counterfeiting ring 4 during upward rotation. When the inner cap 1 separates from the anti-counterfeiting ring 4, the anti-counterfeiting ring 4 radially contracts and resets until its inner diameter is smaller than the outer diameter of the inner cap 1. At this point, when the inner cap 1 is rotated downward, the bottom of the inner cap 1 is no longer restrained by the top of the anti-counterfeiting ring 4 and cannot be reset, thus ensuring the bottle cap is securely opened.

[0030] The bottle cap of the present invention is provided with an elastically shrinkable anti-counterfeiting ring 4, which is directly sleeved on the outer wall of the inner cap 1 when the bottle cap is assembled. During the assembly process of the bottle cap, the anti-counterfeiting ring 4 will not be forcibly interfered with any component of the bottle cap, thereby reducing the risk of material threads appearing when the bottle cap is assembled and opened; at the same time, when the bottle cap is opened and screwed back, the anti-counterfeiting ring 4 is surface-to-surface fitted between the inner cap 1 and the component 2, and there will be no risk of the inner cap 1 being reset by screwing back.

[0031] Example 2:

[0032] In this embodiment, based on the first embodiment, a display ring is coaxially provided on the upper end of the security ring 4. The thickness of the display ring is adapted to the width of the gap, that is, the outer wall of the display ring is in contact with the inner wall of the folded edge, and the inner wall of the display ring is in contact with the outer wall of the inner cover 1. The display ring extends from the gap to the upper end of the lower sleeve 3. The display ring has the same opening as the security ring 4.

[0033] The display ring and the anti-counterfeiting ring 4 are an integrated structure.

[0034] The outer wall of the display ring can be engraved with the word "opened". After the bottle cap is opened, the top of the display ring limits the inner cover 1 to return to its original position. Setting the display ring can make the reminder effect after the bottle cap is opened more obvious.

[0035] Example 3:

[0036] The difference between this embodiment and embodiment 1 is that the anti-counterfeiting ring is a spiral spring. During assembly, the inner ring of the spiral spring expands, and after the bottle cap is opened, the inner ring of the spiral spring contracts to limit the inner cap.

[0037] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the concept described herein through the above teachings or techniques or knowledge in the relevant fields. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention are intended to be protected by the claims appended hereto.
