Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, and in particular to a one-piece bottle cap that is easy to recycle. Background Technology

[0002] Currently, in the market, mineral water bottles, cola bottles, and other beverage bottles commonly have anti-theft rings on the caps that are fixed to the bottle body when consumers are drinking, while the cap body is detached from the bottle body. Consumers have to hold the cap in their hand or place it elsewhere, which makes the cap body easy to lose and increases the difficulty of recycling.

[0003] To address this, an existing patent (authorization announcement number: CN217171606U) discloses a convenient recyclable one-piece bottle cap, comprising a bottle cap body, a connecting area, and an anti-theft ring. The bottle cap body is connected to the anti-theft ring via the connecting area. The connecting area is provided with a first connecting part and a second connecting part. One end of the first connecting part is connected to the anti-theft ring, and the other end of the first connecting part is connected to the bottle cap body. One end of the second connecting part is connected to the anti-theft ring, and the other end of the second connecting part is connected to the bottle cap body. The bottle cap body is also referred to as the cap body.

[0004] When the aforementioned integrated bottle cap is opened and used, although the cap body will not detach from the bottle body, when the bottle body is tilted for use, the cap connected to the anti-theft ring will automatically close towards the bottle opening. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an easy-to-recycle integrated bottle cap, which aims to solve the technical problem that when the bottle body is poured out after the existing bottle cap is opened and used, the cap connected to the anti-theft ring will automatically close with the cap facing the bottle opening.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A recyclable integrated bottle cap includes a cap body, connecting bridges, connecting straps, and an anti-theft ring. The anti-theft ring is connected to the lower part of the cap body via several connecting bridges and is coaxial with the cap body. The anti-theft ring is also connected to the cap body via the connecting straps. A fixing part is provided on the outer wall of the cap body, and a locking part is provided on the outer wall of the anti-theft ring to lock the fixing part. In the open state, each connecting bridge is disconnected, the connecting straps connect the cap body to the anti-theft ring, and the fixing part is locked by the locking part.

[0007] Furthermore, the fixing part is configured as a flange, and the locking part is configured as a slot capable of locking the flange.

[0008] Furthermore, when the fixing part is locked by the locking part, the cover is in a horizontal state.

[0009] Furthermore, an elongated groove is formed on the outer wall of the anti-theft ring along its circumference. The elongated groove penetrates the inner wall of the anti-theft ring, and the first end of the elongated groove penetrates the upper end face of the anti-theft ring along its axial direction. The connecting band is formed on the anti-theft ring at the part located in the elongated groove.

[0010] Furthermore, along the axial direction of the cover, the flange and the slot are on the same straight line.

[0011] Furthermore, a tear groove is provided on the outer wall of the anti-theft ring. The tear groove extends along the axial direction of the anti-theft ring and is located below the second end of the elongated groove.

[0012] Furthermore, the cross-section of the tear groove has a V-shaped structure.

[0013] Furthermore, two protrusions are provided on the outer wall of the anti-theft ring, and the two protrusions are spaced apart along the axial direction of the anti-theft ring, with the gap between the two protrusions forming the slot.

[0014] Furthermore, the wall thickness of the anti-theft ring at the tear groove position is 0.1 mm.

[0015] Furthermore, the cover, connecting bridge, connecting strip, and anti-theft ring are integrally injection molded.

[0016] Compared with existing technologies, the significant advantages of this utility model are: When using the integrated bottle cap of this utility model, the anti-theft ring is connected and fixed to the outer wall of the bottle opening. After opening the cap, the connecting bridge is disconnected, and the connecting strap connects the cap body to the anti-theft ring. The fixing part is locked by the locking part. In this way, the cap body will not detach from the bottle body, and when the bottle body is tilted for use, the cap body connected to the anti-theft ring will not automatically close towards the bottle opening, thus facilitating use.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] In this invention, unless otherwise expressly specified and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or contact between the first and second features not being in direct contact but through another feature between them.

[0022] Please refer to Figures 1-13 This utility model provides an easy-to-recycle integrated bottle cap, including a cap body 1, a connecting bridge 2, an anti-theft ring 3, and a connecting strap 4.

[0023] Reference Figure 1 The anti-theft ring 3 is connected to the bottom of the cover 1 by several connecting bridges 2. In addition, the anti-theft ring 3 is also connected to the cover 1 by connecting straps 4. Of course, the anti-theft ring 3 and the cover 1 are coaxial.

[0024] Reference Figure 7 , Figure 8 Multiple anti-theft teeth 30 are integrally connected to the inner wall of the anti-theft ring 3, and the multiple anti-theft teeth 30 are distributed along the circumference of the anti-theft ring 3; the inner wall of the cap body 1 also has threads 10, which are used to match the threads on the outer wall of the bottle mouth 5. When the anti-theft bottle cap is screwed onto the bottle mouth 5, the anti-theft teeth 30 are locked with the anti-theft retaining ring 50 on the bottle mouth 5, so that the bottle cap can play a role in engaging with the bottle mouth 5 during use, and prevent the anti-theft ring 3 from being pulled out of the bottle mouth 5 after the anti-theft bridge is broken; the outer wall of the cap body 1 is also provided with anti-slip parts to prevent slippage when rotating the cap body 1.

[0025] Reference Figure 2 and Figure 4 The outer wall of the cover 1 is also provided with a fixing part, and the outer wall of the anti-theft ring 3 is provided with a locking part that can lock the fixing part; wherein, in the open state, each connecting bridge 2 is disconnected, the connecting strip 4 connects the cover 1 to the anti-theft ring 3, the fixing part is locked by the locking part, and the cover 1 is in a horizontal state.

[0026] In summary, it can be understood that after the bottle cap is opened, the connecting bridge 2 is twisted off, while the anti-theft ring 3 remains connected and fixed to the outer wall of the bottle opening 5. Since the connecting strap 4 connects the cap 1 to the anti-theft ring 3, the cap 1 will not detach from the bottle body, thus avoiding the phenomenon that the cap 1 is easily lost and facilitating recycling. In addition, in the open state, since the fixing part on the cap 1 is locked by the locking part on the anti-theft ring 3, even if the bottle body is tilted for use, the cap 1 connected to the anti-theft ring 3 will not automatically close towards the bottle opening 5, thus facilitating use.

[0027] For example, the integrated bottle cap of this embodiment is applied to a beverage bottle. After the consumer opens the cap 1, the fixing part on the cap 1 is locked by the locking part of the anti-theft ring 3 fixed to the bottle body. At this time, the cap 1 is in a horizontal state. In this way, when the consumer holds the bottle body and tilts it to drink water, the cap 1 will not automatically close towards the bottle mouth 5, thereby avoiding the cap 1 from touching the consumer's face.

[0028] Of course, in other embodiments, the integrated bottle cap of this embodiment can also be applied to medicine bottles or other plastic bottles, and is not limited here.

[0029] In this embodiment, refer to Figure 1 , Figure 4 and Figure 5 The fixing part is a flange 11 integrally connected to the outer wall of the cap 1, and the locking part is a slot 31 provided on the outer wall of the anti-theft ring 3. Of course, the slot 31 can lock the flange 11. Specifically, it can be understood that when the cap is open, the flange 11 is locked in the slot 31, and the cap 1 is in a horizontal state. Even if the bottle is tilted, the cap 1 connected to the anti-theft ring 3 will not automatically close towards the bottle opening 5.

[0030] In other embodiments, the fixing part can be a magnet fixed to the outer wall of the cap 1, and the locking part can be a magnet fixed to the outer wall of the anti-theft ring 3. The magnet on the outer wall of the cap 1 and the magnet on the outer wall of the anti-theft ring 3 are magnetically attracted to each other. When the cap is open, the magnet on the outer wall of the cap 1 is magnetically attracted and fixed by the magnet on the outer wall of the anti-theft ring 3. Thus, even when the bottle is tilted, the cap 1 connected to the anti-theft ring 3 will not automatically close towards the bottle opening 5. Therefore, it is clear that those skilled in the art can reasonably modify the structure of the fixing and locking parts to fall within the protection scope of this utility model.

[0031] In this embodiment, refer to Figure 1 and Figure 5 Two protrusions 311 are integrally connected to the outer wall of the anti-theft ring 3. The two protrusions 311 are spaced apart along the axial direction of the anti-theft ring 3, so that the gap between the two protrusions 311 forms the aforementioned slot 31. This ensures that the outer side of the flange 11 (the outer side of the flange 11 refers to the surface of the flange 11 facing away from the cover 1) is flush with the outer side of the slot 31 (the outer side of the slot 31 refers to the surface of the protrusion 311 facing away from the anti-theft ring 3). To a certain extent, this can reduce the degree of twisting and stretching of the connecting strip 4 and prevent the connecting strip 4 from breaking.

[0032] In this embodiment, along the axial direction of the cover 1, the flange 11 and the slot 31 are on the same straight line. In this way, after the cover 1 is opened, the flange 11 on the cover 1 can be easily engaged and locked with the slot 31 on the anti-theft ring 3, ensuring that the flange 11 can be locked into the slot 31 after each opening of the cover.

[0033] In this embodiment, refer to Figure 1The anti-theft ring 3 has a long groove 32 circumferentially formed on its outer wall, penetrating the inner wall of the anti-theft ring 3. The first end of the long groove 32 extends axially through the upper surface of the anti-theft ring 3, forming the connecting strip 4 at the portion of the anti-theft ring 3 within the long groove 32. This facilitates the integral injection molding of the connecting strip 4 and the anti-theft ring 3. Furthermore, the anti-theft ring 3 also has a tear groove 33 on its outer wall, extending axially and located below the second end of the long groove 32. The tear groove 33 primarily allows the anti-theft ring 3 to break easily, thus facilitating the separation of the anti-theft ring 3 from the bottle neck 5 when recycling the attached bottle cap.

[0034] In this embodiment, refer to Figure 1 The cross-section of the tear groove 33 is V-shaped, and the wall thickness of the anti-theft ring 3 at the location of the tear groove 33 is D. Figure 13 As shown, D=0.1mm, which further allows the anti-theft ring 3 to easily break at the position of the tear groove 33.

[0035] In this embodiment, the cap 1, connecting bridge 2, connecting strip 4 and anti-theft ring 3 are integrally injection molded from PE material, which can shorten the production cycle of the one-piece bottle cap in this embodiment.

[0036] In this embodiment, refer to Figure 3 The length of the connecting strap 4 is 14 mm. If it is too long, it will affect the fixing effect after the cover 1 is flipped over. If it is too short, it will affect the opening and closing action of the cover 1.

[0037] The working principle of this utility model: When opening the cap, rotate the cap 1 counterclockwise. The connecting bridge 2 is broken. At this time, the connecting strap 4 remains connected to the cap 1 on the outer wall of the bottle mouth 5. Flip the cap 1 so that it is horizontal. At this time, the flange 11 is locked in the slot 31. When closing the cap, simply pry the cap 1 upwards. After the flange 11 disengages from the slot 31, tighten the cap 1 clockwise. Repeat the above actions to open and close the cap. When recycling, the cap 1 is in the open state. Tear the cap 1 counterclockwise. Since the wall thickness of the tear groove 33 is 0.1mm, it can be easily torn. Therefore, during the tearing action, the anti-theft ring 3 will break first at the tear groove 33 without causing the connecting strap 4 to break. This ensures that the anti-theft ring 3 can disengage from the bottle mouth 5 during the tearing process without causing the connecting strap 4 to break. In this way, the complete cap can be separated from the bottle body. Moreover, the PET bottle body and PE bottle cap can be completely sorted and recycled without the use of tools, making the integrated bottle cap of this embodiment efficient and convenient in the recycling process.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
