Abstract
Description
[0001] The priority information claimed in this application is: 202521258624.3, application title: One-piece cap and bottle, application date: June 19, 2025. Technical Field
[0002] This utility model relates to the field of bottle cap technology, and in particular to an integrated cap and bottle. Background Technology
[0003] Bottle caps are typically attached to bottles to seal the opening, prevent leakage of the contents, and ensure the quality and safety of the contents. For example, common beverage bottles such as mineral water and cola bottles have internal threads on the caps. These threads engage with the external threads on the bottle opening to tighten the cap onto the bottle. When consumers drink, the cap detaches from the bottle opening. Consumers must hold the cap in their hand or place it elsewhere, making it easy for the cap to roll off and get lost. This is inconvenient, increases the difficulty of recycling, and can contribute to environmental pollution. Utility Model Content
[0004] The purpose of this utility model is to provide an integrated cap that connects to the bottle body after the bottle opening, preventing the cap from rolling off and being lost. The integrated cap and the bottle body can be recycled simultaneously, thus avoiding environmental damage.
[0005] The purpose of this invention is to provide a bottle in which the integrated cap is connected to the bottle body after the bottle opening is completed, preventing the integrated cap from rolling off and being lost. The integrated cap and the bottle body can be recycled simultaneously to avoid environmental damage.
[0006] To achieve this objective, the technical solution adopted by this utility model is as follows:
[0007] An integral cap includes a bottle cap and a locking ring. The bottle cap is configured to be screwed onto the bottle opening of a bottle body, and the locking ring is configured to be rotatably engaged in a limiting groove in the bottle opening. The bottle cap includes an integrally connected cap body and a connecting part, and the bottom of the connecting part is integrally connected to the locking ring.
[0008] A first break line is provided between the cover and the locking ring. The first break line is arranged along the circumference of the cover and is not closed. A second break line is provided between the connecting part and the cover on both sides along the circumference of the cover. The second break line is V-shaped, and the V-shaped openings of the two second break lines are opposite and both face the circumference of the cover. The two ends of the first break line are respectively connected to the bottom end of the corresponding second break line along the height direction of the cover.
[0009] As an optional solution, the cap body forms two triangular portions at the second fracture line, with the tips of the two triangular portions facing each other; when the cap is unscrewed, the tips of the two triangular portions can engage in the limiting groove.
[0010] As an optional solution, the connecting part forms a V-shaped groove at the second break line; when the bottle cap is screwed onto the bottle mouth, the central angle corresponding to the distance between the tips of the two V-shaped grooves along the circumference of the cap body is 15° to 30°.
[0011] As an optional solution, the second fracture line includes a first oblique line and a second oblique line connected in a V-shape. Along the height direction of the cover, the first oblique line is located above the second oblique line, one end of the first oblique line is connected to one end of the second oblique line, and the end of the second oblique line away from the first oblique line is connected to the end corresponding to the first fracture line.
[0012] When the bottle cap is screwed onto the bottle opening, the angle between the first oblique line and the second oblique line is 25° to 35°.
[0013] As an optional solution, an unclosed third break line is provided circumferentially inside the locking ring, and the third break line is located below the two second break lines.
[0014] As an optional feature, the central angle corresponding to the circumferential length of the third fracture line along the locking ring is 45° to 90°.
[0015] As an optional solution, when the bottle cap is screwed onto the bottle opening, the distance between the first break line and the third break line along the height direction of the cap body is 1.5mm to 2mm.
[0016] As an alternative, multiple bridge nodes are arranged at intervals along the circumference of the cover within the first fracture line, and the cover is connected to the locking ring through the bridge nodes.
[0017] As an optional feature, the cover is provided with multiple stripes at intervals on its circumferential outer side.
[0018] The bottle includes a bottle body and the aforementioned integrated cap, which is screwed onto the bottle mouth of the bottle body.
[0019] The beneficial effects of this utility model are as follows:
[0020] The integrated cap proposed in this utility model disconnects the first break line between the cap body and the locking ring, and the second break line between the cap body and the connecting part, when the bottle opening is unscrewed, allowing the cap body to open the bottle opening. Because the locking ring rotates and engages within the limiting groove of the bottle opening, and the cap body is connected to the locking ring as a single unit via the connecting part, the integrated cap remains connected to the bottle opening after opening, preventing the integrated cap from rolling off and being lost. This facilitates the synchronous recycling of the integrated cap and the bottle body, contributing to environmental protection.
[0021] Furthermore, because the second fracture line is V-shaped, and the V-shaped openings of the two second fracture lines are opposite and both face circumferentially towards the cap, the distance between the tips of the V-shapes of the two second fracture lines is small. This facilitates the stretching deformation of the connecting part when the bottle cap is unscrewed, allowing the cap to be fully opened. Moreover, the simple structure of the first and second fracture lines in the one-piece cap facilitates the integral processing of the one-piece cap, reducing the processing difficulty and cost.
[0022] The bottle proposed in this utility model includes the aforementioned integrated cap. After the bottle opening is completed, the integrated cap remains connected to the bottle opening, preventing it from rolling off and being lost. This facilitates simultaneous recycling of the integrated cap and the bottle, contributing to environmental protection. Simultaneously, the second fracture line is V-shaped, allowing the connecting part to stretch and deform when the cap is unscrewed, enabling the cap to be fully opened. Furthermore, the simple structure of the first and second fracture lines in the integrated cap facilitates its integral molding, reducing the processing difficulty and cost.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0033] When the bottle cap detaches from the bottle opening, consumers have to hold the cap in their hand or place it elsewhere, making it easy for the cap to roll off and get lost. This is inconvenient, increases the difficulty of recycling, and can easily cause environmental pollution.
[0034] To solve the above problems, such as Figure 1 and Figure 2As shown, this embodiment proposes a one-piece cap, which includes a bottle cap 1 and a locking ring 2. The bottle cap 1 is configured to be screwed onto the bottle opening 10 of the bottle body, and the locking ring 2 is configured to be rotatably engaged in the limiting groove 101 of the bottle opening 10. The bottle cap 1 includes an integrally connected cap body 11 and a connecting part 12, the bottom of which is integrally connected to the locking ring 2. A first break line 110 is provided between the cap body 11 and the locking ring 2. The first break line 110 is arranged along the circumference of the cap body 11 and is not closed. A second break line 120 is provided between the connecting part 12 and the cap body 11 on both sides along the circumference of the cap body 11. The second break lines 120 are V-shaped, and the V-shaped openings of the two second break lines 120 are opposite and both face the circumference of the cap body 11. The two ends of the first break line 110 are respectively connected to the bottom end of the corresponding second break line 120 along the height direction of the cap body 11.
[0035] When the bottle cap 1 is unscrewed from the bottle opening 10, the first break line 110 between the cap body 11 and the locking ring 2, and the second break line 120 between the cap body 11 and the connecting part 12, are broken, allowing the cap body 11 to open the bottle opening 10. Since the locking ring 2 rotates and engages in the limiting groove 101 of the bottle opening 10, the cap body 11 is connected to the locking ring 2 as a whole through the connecting part 12. This ensures that the integrated cap remains connected to the bottle opening 10 after it is opened, preventing the integrated cap from rolling off and being lost. It also facilitates the synchronous recycling of the integrated cap and the bottle body, which is beneficial to environmental protection. In addition, since the second break line 120 is V-shaped, and the V-shaped openings of the two second break lines 120 are opposite and both face the circumference of the cap body 11, the distance between the tips of the V-shapes of the two second break lines 120 is small. This allows the connecting part 12 to undergo tensile deformation when the bottle cap 1 is unscrewed from the bottle opening 10, enabling the cap body 11 to fully open the bottle opening 10. Moreover, the structure of the first fracture line 110 and the second fracture line 120 in the one-piece cover is simple, which facilitates the integral processing and molding of the one-piece cover, reducing the processing difficulty and processing cost of the one-piece cover.
[0036] It should be noted that the inner circumferential sidewall of the cap 11 is provided with internal threads, and the outer circumferential sidewall of the bottle mouth 10 is provided with external threads and a limiting groove 101, with the limiting groove 101 located below the external threads. The cap 11 is screwed onto the bottle mouth 10 by the interlocking of the internal threads with the external threads at the bottle mouth 10. The locking ring 2 is fitted into the limiting groove 101 and can rotate relative to the limiting groove 101, so that the locking ring 2 rotates synchronously with the bottle cap 1 as the bottle mouth 1 is unscrewed. During the screwing process of the bottle cap 1 to open the bottle mouth 10, the distance between the cap 11 and the locking ring 2 gradually increases until they separate along the first fracture line 110. As the screwing process continues, the distance between the cap 11 and the locking ring 2 continues to increase. The locking ring 2 remains within the limiting groove 101. The connecting part 12 undergoes tensile deformation along the height direction of the cap 11, causing the cap 11 and the connecting part 12 to separate along the second fracture line 120. Finally, the cap 1 is unscrewed from the bottle opening 10, and the internal thread of the cap 11 disengages from the external thread of the bottle opening 10. At this time, the tensile deformation of the connecting part 12 is reset or at least partially reset. The cap 11 can be flipped outward from the bottle opening 10 and completely expose the bottle opening 10, that is, the cap 11 fully opens the bottle opening 10. At this time, the connecting part 12 bends outward when the cap 11 is flipped.
[0037] like Figure 1 and Figure 2 As shown, the cap 11 forms two triangular portions 111 at the second fracture line 120, with the tips of the two triangular portions 111 facing each other. When the cap 1 is unscrewed from the bottle opening 10, the tips of the two triangular portions 111 can engage in the limiting groove 101. The cap 11 forms two triangular portions 111 on the narrowest sides of the connecting portion 12. When the cap 1 is unscrewed from the bottle opening 10, the stretched and deformed connecting portion 12 returns to its original position, at which time the triangular portions 111 are located above and adjacent to the locking ring 2. When the cap 11 is flipped outward from the bottle opening 10 and the bottle opening 10 is fully exposed, the triangular portions 111 extend into and engage in the limiting groove 101 (the triangular portions 111 engage between the locking ring 2 and the inner wall of the limiting groove 101) to fix the cap 11 at a specific flipping angle.
[0038] like Figure 2As shown, the connecting part 12 forms a V-groove 121 at the second fracture line 120. When the bottle cap 1 is screwed onto the bottle mouth 10, the central angle corresponding to the distance between the tips of the two V-grooves 121 along the circumference of the cap body 11 is 15° to 30°. This design reduces the width of the connecting part 12 at the tips of the two V-grooves 121, increasing its flexibility and facilitating tensile deformation when the bottle cap 1 is unscrewed from the bottle mouth 10, allowing the cap body 11 to fully open the bottle mouth 10. The central angle corresponding to the distance between the tips of the two V-grooves 121 along the circumference of the cap body 11 can be 15°, 20°, 25°, or 30°, etc., to ensure a suitable width for the connecting part 12 at the tips of the two V-grooves 121. This maximizes the flexibility of the connecting part 12 while maintaining its structural strength, allowing for smooth tensile deformation and bending. If the central angle corresponding to the distance between the tips of the two V-grooves 121 along the circumference of the cap 11 is too small, that is, the width of the connecting part 12 at the tip position of the two V-grooves 121 is too small, the connecting part 12 is prone to breakage; if the central angle corresponding to the distance between the tips of the two V-grooves 121 along the circumference of the cap 11 is too large, that is, the width of the connecting part 12 at the tip position of the two V-grooves 121 is too large, the flexibility of the connecting part 12 decreases, making it difficult to achieve stretching deformation and bending action, increasing the difficulty of opening the bottle mouth 10 of the cap 1.
[0039] In this embodiment, the second break line 120 includes a first oblique line 1201 and a second oblique line 1202 connected in a V-shape. Along the height direction of the cap 11, the first oblique line 1201 is located above the second oblique line 1202. One end of the first oblique line 1201 is connected to one end of the second oblique line 1202, and the end of the second oblique line 1202 away from the first oblique line 1201 is connected to the end corresponding to the first break line 110. When the bottle cap 1 is screwed onto the bottle mouth 10, the angle between the first oblique line 1201 and the second oblique line 1202 is 25° to 35°. This design simplifies the structure of the break line and facilitates the integral processing of the cap. The angle α between the first oblique line 1201 and the second oblique line 1202 can be 25°, 27°, 30°, 32°, or 35°, etc., to ensure that the triangular portion 111 has appropriate dimensions and structural strength, guaranteeing that the triangular portion 111 is stably engaged within the limiting groove 101. If the included angle α is too small, the tip of the triangular part 111 will be too thin, resulting in low structural strength. It will easily deform and slip out of the limiting groove 101, thus failing to effectively fix the bottle cap 1. If the included angle α is too large, the tip of the triangular part 111 will be too wide, making it unable to extend into the limiting groove 101, which also fails to effectively fix the bottle cap 1.
[0040] like Figure 1 and Figure 2As shown, an unclosed third break line 21 is provided circumferentially inside the locking ring 2, and the third break line 21 is located below the two second break lines 120. By providing the third break line 21, when the connecting part 12 is stretched and deformed when the bottle cap 1 is unscrewed from the bottle opening 10, part of the structure of the locking ring 2 can also be stretched and deformed along with the connecting part 12, effectively reducing the amount of deformation of the connecting part 12 during stretching deformation, avoiding breakage of the connecting part 12 during stretching deformation, and improving the protection of the bottle cap 1.
[0041] In an optional embodiment, the central angle corresponding to the circumferential length of the third fracture line 21 along the locking ring 2 is 45° to 90°. Specifically, the central angle corresponding to the circumferential length of the third fracture line 21 along the locking ring 2 can be 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, or 90°, etc., so that the third fracture line 21 has a suitable length, increasing the amount of deformation of the locking ring 2 under tensile deformation with the connecting part 12. If the central angle corresponding to the circumferential length of the third fracture line 21 along the locking ring 2 is too small, it is difficult to effectively reduce the amount of deformation of the connecting part 12 under tensile deformation, weakening the protection of the bottle cap 1; if the central angle corresponding to the circumferential length of the third fracture line 21 along the locking ring 2 is too large, it reduces the structural strength of the locking ring 2, and at the same time makes it difficult for the first fracture line 110 and the second fracture line 120 to break and separate in time.
[0042] like Figure 1 As shown, when the bottle cap 1 is screwed onto the bottle opening 10, the distance between the first fracture line 110 and the third fracture line 21 along the height direction of the cap body 11 is 1.5mm to 2mm. The distance H between the first fracture line 110 and the third fracture line 21 can be 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, or 2mm, etc., to maintain a suitable distance between the first fracture line 110 and the third fracture line 21, so as to balance the tensile deformation and structural strength of the locking ring 2. If the distance H is too small, the distance between the first fracture line 110 and the third fracture line 21 will be too close, which is not conducive to the integrated processing of the cap. At the same time, it will result in low strength of the part of the locking ring 2 that undergoes tensile deformation, making it easy for the locking ring 2 to break. If the distance H is too large, the distance between the first fracture line 110 and the third fracture line 21 will be too far, resulting in a decrease in the flexibility of the part of the locking ring 2 that undergoes tensile deformation, increasing the difficulty of the locking ring 2 undergoing tensile deformation, and thus increasing the difficulty of opening the bottle opening 10 with the bottle cap 1.
[0043] like Figure 1 and Figure 2 As shown, the outer circumferential surface of the cap 11 is provided with a plurality of stripes 112 at intervals. By setting a plurality of stripes 112, the friction between the cap 11 and the fingers is increased, making it easier for the fingers to grip the cap 11 and preventing the fingers from slipping during the twisting of the cap 11, thus realizing quick installation and removal of the cap 1 at the bottle mouth 10.
[0044] In an optional embodiment, multiple bridge nodes are spaced circumferentially along the cover 11 within the first fracture line 110, and the cover 11 is connected to the locking ring 2 through the bridge nodes. By setting the bridge nodes, the cover 11 and the locking ring 2 are connected as one unit, increasing the connection strength and stability between the cover 11 and the locking ring 2.
[0045] This embodiment also proposes a bottle, which includes a bottle body and the aforementioned integrated cap, the integrated cap being screwed onto the bottle mouth 10 of the bottle body. After the bottle mouth 10 is opened, the integrated cap remains connected to the bottle mouth 10, preventing the integrated cap from rolling off and being lost, facilitating the synchronous recycling of the integrated cap and the bottle body, and contributing to environmental protection. Simultaneously, the second fracture line 120 is V-shaped, facilitating the stretching deformation of the connecting part 12 when the cap 1 is unscrewed from the bottle mouth 10, allowing the cap 11 to fully open the bottle mouth 10. Furthermore, the simple structure of the first fracture line 110 and the second fracture line 120 in the integrated cap facilitates the integral processing and molding of the integrated cap, reducing the processing difficulty and cost.
[0046] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
