Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle cap production, in particular to an easy-to-wash plastic cap folding structure. Background Art

[0002] The folding edge structure of the bottle cap is mainly used to enhance the sealing and prevent leakage of contents, while improving safety and preventing tampering. It achieves a tighter closure by increasing the contact area between the bottle cap and the bottle mouth. In addition, the folding edge design also optimizes the production process, such as the in-mold automatic folding technology, which improves production efficiency. For consumers, the folding edge structure also improves the convenience of opening the cap. In general, the bottle cap folding edge structure is an important design element to ensure the sealing, safety and convenience of the product.

[0003] The utility model with the authorization publication number CN213444041U provides a bottle cap folding structure, which belongs to the technical field of "plastic bottle cap production" and the protected claim is: "It includes a bottle cap lower cover, and a circle of lower cover folding edges that gradually close from top to bottom are arranged on the bottom circumference of the bottle cap lower cover. When the bottle cap lower cover is not installed on the bottle mouth, the lower cover folding edge remains naturally drooping and tilted inward; a circle of protrusions is arranged on the outer side of the lower end of the lower cover folding edge, and the bottom surface and the outer side surface of the protrusion are at a 90-degree angle. When the bottle cap lower cover is installed on the bottle mouth, The folded edge of the lower cover is kept folded inward and nearly vertically upward. At this time, the bottom surface of the protrusion is tightly fitted with the lower surface of the lower locking ring of the bottle mouth, and the outer side surface of the protrusion is tightly fitted with the outer wall of the bottle mouth below the lower locking ring of the bottle mouth. After the folded edge of the lower cover of the utility model is folded inward and entered into the lower cover of the bottle cap, it can tightly press upward against the lower locking ring of the bottle mouth, ensuring that the gap below the lower locking ring of the bottle mouth is filled and full, playing a snap-fit ​​role while making the lower cover of the bottle cap and the bottle mouth more tightly connected, even if it is pulled excessively or forcibly damaged, it is not easy to fall off.

[0004] In this device, although the connection can be made tighter by folding and snapping, this device is not conducive to flushing. For this reason, we propose a plastic cover folding structure that is easy to flush. Utility Model Content

[0005] The utility model aims to provide an easy-to-wash plastic cover folding structure to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. Rotate the outer cover through the first anti-slip groove and the second anti-slip groove, and the inner cover is released from the threaded connection with the bottle mouth. At the same time, the multiple first folded edges in the inner cover are pulled from the second notch to the first notch and snapped with the first notch. Since the diameter at the first notch is smaller than the diameter at the second notch, but the multiple first folded edges are snapped with the first notch, there are multiple gaps between the multiple first folded edges and the first notch. At this time, put the bottle body, bottle mouth, inner cover and outer cover into water for flushing. Since the first folded edge is not released from the first notch, the flushing water can enter the inner cover and the bottle mouth through the multiple gaps for flushing. In this way, the bottle body, bottle mouth, inner cover and outer cover can be assembled together for flushing to avoid the inner cover and outer cover being lost during the flushing process.

[0017] 2. During flushing, water flows in at high speed from multiple arc grooves and inclined grooves of the outer cover and the bottom of the outer cover, and is guided by multiple second folded edges to form vortices. The vortices generate stronger impact and friction forces. When these forces act on the inner surfaces of the outer cover, inner cover and bottle mouth, they can effectively peel off and wash away the dirt and residues attached to their surfaces.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] like Figure 1-4 As shown, in this embodiment, the easy-to-wash plastic cover folding structure includes a bottle body 100, an inner cover 300 and an outer cover 400. The bottle body 100 is fixedly connected with a bottle mouth 200, and the bottle mouth 200 is fixedly connected with a first thread 210. The bottle mouth 200 is provided with a first notch 220 and a second notch 230. The first notch 220 is located at the top of the second notch 230. The inner cover 300 is arranged on the bottle mouth 200, and the inner cover 300 is fixedly connected with the second thread 310. The inner cover 300 and the bottle mouth are fixedly connected. 200 is threadedly connected by a first thread 210 and a second thread 310, and a plurality of first folded edges 320 are fixedly connected inside the inner cover 300, and the plurality of first folded edges 320 are movably engaged with the first notch 220 and the second notch 230 in sequence; the outer cover 400 is fixedly connected to the top of the inner cover 300; a plurality of first anti-slip grooves 440 and second anti-slip grooves 450 are provided on the outer side of the outer cover 400; a plurality of reinforcing columns 330 are fixedly connected to the outer side of the inner cover 300, and the reinforcing columns 330 are used for strengthening fixation.

[0026] During specific implementation, the outer cover 400 is rotated through the first anti-slip groove 440 and the second anti-slip groove 450, and the inner cover 300 is released from the threaded connection with the bottle mouth 200. At the same time, the multiple first folded edges 320 in the inner cover 300 are pulled from the second notch 230 to the first notch 220 and snap-fit ​​with the first notch 220. Since the diameter at the first notch 220 is smaller than the diameter at the second notch 230, but the multiple first folded edges 320 are snap-fitted with the first notch 220, there are multiple gaps between the multiple first folded edges 320 and the first notch 220. At this time, the bottle body 100, the bottle mouth 200, the inner cover 300 and the outer cover 400 are all put into water for washing. When washing, since the first folded edge 320 is not released from the first notch 220, the washing water can enter the inner cover 300 and the bottle mouth 200 through multiple gaps for washing, so that the bottle body 100, the bottle mouth 200, the inner cover 300 and the outer cover 400 can be assembled together for washing, avoiding the inner cover 300 and the outer cover 400 from being lost during the washing process. Since the multiple first folded edges 320 are made of high-toughness material, the inner cover 300 and the outer cover 400 can be directly pulled off by applying force to separate the inner cover 300, the outer cover 400 from the bottle mouth 200. In addition, when the multiple first folded edges 320 are clamped with the second notch 230, the tightness of their connection can be enhanced.

[0027] Embodiment 2

[0028] like Figure 1-4As shown, in this embodiment, a plurality of inclined grooves 410 are formed through the outer side of the outer cover 400, a plurality of second folded edges 420 are fixedly connected to the inner side of the inner cover 300, and the plurality of second folded edges 420 are all inclined downward; the bottom position of the outer cover 400 is lower than the bottom position of the inner cover 300, and the bottom end positions of the plurality of second folded edges 420 are lower than the bottom end positions of the inner cover 300; the top diameter of the bottle mouth 200 is smaller than its bottom diameter.

[0029] In specific implementation, when flushing, water flows in at high speed from the multiple arc grooves 430 and the inclined grooves 410 of the outer cover 400 and the bottom of the outer cover 400, and is guided by the multiple second folded edges 420 to form vortices. The vortices generate stronger impact force and friction force. When these forces act on the inner surfaces of the outer cover 400, the inner cover 300 and the bottle mouth 200, they can effectively peel off and wash away the dirt and residues attached to their surfaces.

[0030] Working principle: first, rotate the outer cover 400, and the inner cover 300 is released from the threaded connection with the bottle mouth 200. At the same time, the multiple first folded edges 320 in the inner cover 300 are pulled from the second notch 230 to the first notch 220 and snapped with the first notch 220. Since the diameter at the first notch 220 is smaller than the diameter at the second notch 230, but the multiple first folded edges 320 are snapped with the first notch 220, there are multiple gaps between the multiple first folded edges 320 and the first notch 220. At this time, put the bottle body 100, the bottle mouth 200, the inner cover 300 and the outer cover 400 into water for washing. Since the first folded edges 320 are not released from the first notch 220, The flushing water can enter the inner cover 300 and the bottle mouth 200 through multiple gaps for flushing, so that the bottle body 100, the bottle mouth 200, the inner cover 300 and the outer cover 400 can be assembled together for flushing to prevent the inner cover 300 and the outer cover 400 from being lost during the flushing process. During flushing, the water flows in at high speed from the multiple arc grooves 430 and the inclined grooves 410 of the outer cover 400 and the bottom of the outer cover 400, and is guided by the multiple second folded edges 420 to form a vortex. The vortex generates stronger impact force and friction force. When these forces act on the inner surfaces of the outer cover 400, the inner cover 300 and the bottle mouth 200, they can effectively peel off and flush away the dirt and residue attached to their surfaces.
