Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to an integrated folding bottle cap. Background Art

[0002] In daily life, many wines and beverages are packaged by stamping metal bottle caps on glass bottles. This packaging method has a firm connection and good sealing, allowing the product to maintain its original flavor for a long time. Therefore, it is widely used in the packaging of various bottles.

[0003] With the continuous progress of the bottle cap industry, the patent with the authorization announcement number CN221394947U discloses a bottle cap and a packaging bottle, including a main body mechanism and an operating mechanism. The top plate and side walls of the main body mechanism are used to close the bottle mouth of the bottle body and are connected to the bottle body. The main body mechanism also includes a connecting portion, which is connected to the operating handle of the operating mechanism by the connecting portion. When opening the bottle cap, a force is applied to the side of the operating handle close to the bottle body, pushing the operating handle toward the top plate of the cap. The operating handle drives the connecting portion to move, causing it to flip relative to the top plate and the side wall of the cap. The flipping of the connecting portion relative to the side wall of the cap causes the notch to deform, and the side wall of the cap is torn at the notch. Under the action of the internal pressure of the bottle body, the bottle cap is pushed open, achieving the effect of easily opening the bottle cap.

[0004] However, in this solution, the operating mechanism 2 and the main body 1 adopt a split structure. The double-layer structure at the connection not only consumes more metal materials, increasing material costs; moreover, the connection needs to be riveted to connect the operating mechanism 2 and the main body 1 together. The riveting connection speed is slow, which reduces the production efficiency of the bottle cap and increases the production cost. Utility Model Content

[0036] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless there is a conflict.

[0037] Example 1

[0038] This embodiment provides an integrated folding bottle cap, including a bottle cap body, which is in a sheared and folded state. Figure 1-2 As shown, the bottle cap body comprises a top cap 1, with side bands 2 and a flange 3 extending downward from the outer edge of the top cap 1. The side bands 2 and flange 3 are separated by a score line 8. Downward-extending folding strips 4 are provided on either side of the lower end of the flange 3, and the lower ends of the folding strips 4 are integrally connected to a push portion 5. The upper end of the push portion 5 is provided with a connecting piece 6 integrally connected thereto, with gaps between the connecting piece 6, the folding strips 4, and the flange 3. The top cap 1, side bands 2, flange 3, folding strips 4, the push portion 5, and the connecting piece 6 are a one-piece structure, that is, manufactured by stamping and shearing from a single sheet of metal.

[0039] Furthermore, the left and right sides and the lower side of the hand push portion 5 are provided with curling edges 7 connected thereto as a whole. Figure 3 First, fold the three sides of the curling edge 7 inward so that the curling edge 7 fits the inner surface of the hand-pushing portion 5. The curling edge 7 can well protect the user's hands from being cut and can enhance the strength of the hand-pushing portion 5.

[0040] When folding the connecting piece 6 and the folding strip 4, refer to Figure 4-6 , fold the two folding strips 4 in the direction of their inner surfaces so that the inner surfaces of the folding strips 4 are attached together. At the same time, insert the connecting piece 6 into the inner side of the convex edge 3 through the gap, and bend the connecting piece 6 along the boundary line between the hand-pushing part 5 to a certain extent so that the connecting piece 6 is attached to the inner surface of the convex edge 3. After the folding is completed, refer to Figure 7-8The folded folding strip 4 is in contact with the outer surface of the hand-pushing portion 5, the connecting piece 6 is in contact with the inner surface of the convex edge 3, and the hand-pushing portion 5 forms a certain angle with the vertical direction.

[0041] Furthermore, a gasket 10 is provided on the lower surface of the top cover 1, and the gasket 10 is located on the inner side of the score line 8. After the bottle cap body is folded, the gasket 10 is pasted on the lower surface of the top cover 1 to ensure that the bottle cap body and the bottle mouth are fully sealed.

[0042] Furthermore, when the connecting piece 6 is fitted with the convex edge 3 , the top end of the connecting piece 6 is higher than the outer edge of the top cover 1 , making it convenient to use the connecting piece 6 to lift up the top cover 1 when opening the bottle cap.

[0043] Furthermore, the connecting piece 6 is preferably in a trapezoidal shape. When opening the bottle cap, the force exerted on the push portion 5 can be transferred to the top of the connecting piece 6, and the top cover 1 can be lifted up by the narrow top edge of the connecting piece 6.

[0044] Furthermore, at least a portion of the path of the score line 8 is located at the outer edge of the top cover 1, and the end of the score line 8 extends into the side band 2. The score line 8 is provided on the inner surface of the bottle cap body.

[0045] Furthermore, two notches 9 are formed at the lower end of the side band 2 , and the two notches 9 are symmetrically arranged on both sides of the convex edge 3 , and the tops of the notches 9 are connected to the starting ends of the score lines 8 .

[0046] The schematic diagram of the state where the bottle cap body is fixed on the bottle mouth is as follows Figure 9 When opening the bottle cap, the user can operate with one hand. The user only needs to hold the bottle body and then place the finger under the push part 5 to push it upwards. Figure 10 As shown, the outward turning of the push portion 5 drives the inner connecting piece 6 to push upward, causing the score line 8 to crack from the notch 9. After the inner and outer spaces are connected, under the action of the air pressure in the bottle, the score line 8 continues to crack to the end, and at the same time the bottle cap body is collapsed upward, so that the bottle cap body can be easily opened with one hand.

[0047] Example 2

[0048] This embodiment provides an integrated folding bottle cap, including a bottle cap body, which is consistent with the state of embodiment 1 after being cut and not folded. Figure 1-2 shown.

[0049] The difference between this embodiment and embodiment 1 is that:

[0050] When folding the connecting piece 6 and the folding strip 4, refer to Figure 11-12, fold the two folding strips 4 in the direction of their outer surfaces so that the outer surfaces of the folding strips 4 are attached together. At the same time, the connecting piece 6 is inserted into the inner side of the convex edge 3 through the gap, and the connecting piece 6 is bent to a certain extent so that the connecting piece 6 is attached to the inner surface of the convex edge 3. After the folding is completed, refer to Figure 13-14 The folded folding strip 4 is stored inside the hand-pushing portion 5 and fits in with the inner surface of the hand-pushing portion 5. By folding the folding strip 4 and storing it inside the bottle cap, it can not only prevent the folding strip 4 from being exposed to the outside and easily scratching the hands, but also make it more beautiful and simple. Figure 15 This is a schematic diagram of the bottle cap body being fixed to the bottle mouth. Figure 16 This is a schematic diagram after the bottle cap body is pushed open.

[0051] In summary, the bottle cap of the present invention is manufactured by stamping and folding a single sheet of metal material, eliminating the need for riveting, making full use of the sheet material and reducing costs. Furthermore, the one-piece metal bottle cap does not need to be disassembled and sorted during subsequent recycling, and can be recycled as a whole, which is more environmentally friendly. Furthermore, the bottle cap of the present invention can be operated with one hand, making it easier and more convenient. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has high industrial value.
