Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bottle cap, especially to a three-ring color separation dropper bottle cap suitable for sucking bottle liquid and serving as a bottle cap. BACKGROUND

[0002] As a key sealing component of a bottle, a bottle cap is generally firmly fixed on the bottle mouth through a screwing action. In various containers containing liquid, such as beverage bottles commonly seen in daily life, medicine bottles related to health, and cosmetic bottles attracting much attention, bottle caps play an important role in tightly sealing to prevent liquid leakage and foreign matter from entering. A dropper mainly consists of a straw and a suction ball (or a rubber head) and is a tool capable of accurately measuring and taking a small amount of liquid. In the field of cosmetic containers, many cosmetics, such as expensive and precious ingredient products such as essence and essential oil, have higher requirements for the taking method. Using a dropper can accurately control the amount used each time, avoiding waste of cosmetics due to excessive use, and effectively maintaining hygiene and reducing the risk of cosmetic contamination and deterioration. Based on this, the bottle cap and the dropper are ingeniously combined to give birth to a bottle cap with a dropper design, which is increasingly common in cosmetic packaging, providing consumers with a better, more convenient, and hygienic use experience.

[0003] Currently, most dropper bottle caps are designed in a single color, resulting in a single and dull appearance of the bottle cap with poor recognition. Although various coloring processes can be used to combine and attach multiple colors to the surface of the bottle cap to add rich colors, this method is a one-time operation, and once the color of the bottle cap is fixed, it cannot be changed at will. Moreover, any mistake or non-compliance during the coloring process can easily result in waste of materials, and the coloring process often requires the use of chemical pigments and solvents, which not only consume energy during production but also are difficult to degrade, having a significant negative impact on the ecological environment, which is contrary to the current environmental protection concept. For example, the following disclosed Chinese patent documents all have the above-mentioned defects.

[0004] Chinese Utility Model Specification (Publication No. CN210392066U) discloses a convenient organic solvent bottle cap, wherein the bottle cap body 1 is a hollow cylindrical shape, the upper edge of the bottle cap body 1 is connected to a limiting piece 2, and the rubber head part of the straw is clamped above the limiting piece, effectively sealing the gap around the straw. Figure 1 As shown in FIG. 4, the bottle cap body belongs to a single cap structure and is integrally formed.

[0005] The Chinese utility model specification (publication number: CN218390148U) discloses a dropper type essence bottle, wherein the essence bottle main body 6 and the bottle cap 3 are installed together through a threaded structure, a top plate 1 is arranged above the bottle cap, a dropper rubber head 2 is arranged above the top plate 1, and the dropper rubber head 2 is connected with a straw 4 inserted into the bottom of the essence bottle main body 6. Although the bottle cap is provided with the top plate, the top plate only serves as a fixing structure for connecting the bottle cap and the dropper rubber head, and the entire bottle cap still belongs to a single cover body structure and is integrally formed.

[0006] In view of the above, the present inventors have designed the present application based on years of experience in the field of bottles and bottle caps, and have made the present application after considering the structure optimization of the product and after multiple tests and improvements.

EMBODIMENT

[0018] To make the invention purpose, technical scheme and beneficial effects of the utility model clearer, the technical scheme in the utility model embodiment will be described clearly and completely below in combination with the drawings in the utility model embodiment. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments.

[0019] As Figure 1 , Figure 2 , Figure 3As shown, the embodiment shows a three-ring color separation dropper bottle cap, the main structure includes cap body and dropper. Among them, the dropper adopts the existing design, which is composed of a straw and a rubber head. The rubber head is installed at the top end of the straw. In the use process, by extruding the rubber head, the power for the straw to suck the liquid in the bottle can be provided, so as to realize the sucking and transferring of the liquid.

[0020] The cap body is mainly composed of inner shell 1, middle ring 2 and outer shell 3 and other accessories, and is implemented in the following manner in combination with the related drawings.

[0021] The inner shell 1 is a component connected with the bottle mouth, which is manufactured by one-piece forming process. The bottom of the inner shell is designed as a cap 5, which is suitable for the structure of the bottle mouth. An inner layer sleeve hole 10 is arranged in the middle part of the inner shell, which is sleeved on the rubber head 4 of the dropper, so that the cap body and the dropper are connected as a whole. At the same time, based on the inner layer sleeve hole, a cylindrical sleeve 7 is extended upward in the middle part of the inner shell. The inside of the sleeve is in communication with the cap, and a connecting thread 12 is arranged on the inner wall of the sleeve. The connecting thread can tightly engage with the thread structure at the bottle mouth, and the stable connection between the cap body and the bottle mouth is realized through thread cooperation, which guarantees the sealing of the whole bottle cap. A ring-shaped concave surface 9 is arranged around the top outer wall of the sleeve, which is used as the mounting seat of the middle ring and realizes the precise assembly of the middle ring and the inner shell. In addition, the outer wall of the inner shell is a surrounding edge 8 extending upward from the bottom, and the height of the surrounding edge is lower than that of the sleeve. The surrounding edge and the sleeve are separated by a groove.

[0022] The middle ring 2 is a ring-shaped component, which is also manufactured by one-piece forming process. When assembled, the middle ring is sleeved on the sleeve 7 of the inner shell, and the end face is flush or close to the same horizontal plane. A convex part 17 is arranged around the inner wall of the middle ring, which is located in the ring-shaped concave surface 9 of the top outer wall of the sleeve and is supported by the ring-shaped concave surface. In addition, a boss 16 is arranged at the top end of the middle ring. From the cross-sectional view, the boss is in the shape of "convex", which plays a role of sleeve support.

[0023] The outer shell 3 is also manufactured by the one-piece forming process and is sleeved on the surface of the inner shell 1 and is flush with or close to the same horizontal plane of the end surface of the inner shell 1. Meanwhile, the outer shell and the inner shell are fixedly connected by the buckle structure and the rotation-stopping structure. In addition, the outer shell is provided with an outer sleeve hole 20 in the middle of the top surface, which is nested on the boss 16 at the top end of the middle sleeve ring and is supported by the boss. At the same time, the structure effectively limits the up-and-down movement of the middle sleeve ring along the axial direction and ensures the stable position of the middle sleeve ring during use. In this way, the top surfaces of the outer shell, the middle sleeve ring and the inner shell together form three ring bodies arranged from inside to outside, which not only presents a unique layered visual effect in appearance, but also greatly enriches the color design of the appearance of the product and enhances the product recognition. Even more, the layered and colored combination structure can be deeply integrated with the shape design of the cover body, and a more diverse product appearance can be designed, which greatly improves the visual appeal of the product.

[0024] Further, the annular concave surface 9 of the sleeve is provided with a concave arc 14, and the convex part 17 of the middle sleeve ring is provided with a convex arc 18. When assembled, the concave arc and the convex arc are embedded in each other, so that the top end of the middle sleeve ring is fixed on the inner shell in a slight buckle manner. This design realizes the installation and positioning of the middle sleeve ring, and at the same time, the boss at the top end of the middle sleeve ring cooperates with the limiting structure formed by the concave arc and the convex arc to effectively limit the up-and-down movement of the middle sleeve ring along the axial direction of the sleeve of the inner shell and the outer shell.

[0025] Further, the buckle structure is designed as follows: a circle of raised buckling parts 13 is arranged on the outer wall of the lower end of the inner shell 1, and a circle of clamping grooves 21 is arranged on the inner wall of the lower end of the outer shell 3. When assembled, the clamping grooves and the raised buckling parts are buckled and connected with each other. This connection mode makes the outer shell and the inner shell only be able to rotate relative to each other, but cannot be displaced in the up-and-down direction, effectively ensuring the stability of the connection between the outer shell and the inner shell and avoiding the separation of the outer shell and the inner shell during use.

[0026] Further, the rotation-stopping structure is designed as follows: a plurality of protrusions are uniformly distributed along the height direction of the outer wall (i.e. the surrounding edge) of the inner shell 1, and a sliding groove 6 is formed between adjacent protrusions. Correspondingly, eight sliding strips 19 are arranged on the inner wall of the outer shell and extend along the height direction of the inner wall. During assembly, the sliding strips on the inner wall of the outer shell can be precisely slid into the corresponding sliding grooves on the outer wall of the inner shell. After the sliding connection is completed, the rotation of the outer shell relative to the inner shell is effectively prevented, thereby achieving the rotation-stopping effect of the outer shell, ensuring that all parts of the cover body can rotate together during use, and avoiding functional abnormalities or damage caused by relative rotation. In addition, the number of sliding grooves and sliding strips is not limited to the above-mentioned embodiment. In actual application, the number of sliding grooves and sliding strips can be adjusted flexibly according to the complexity of the product structure, the specific requirements for the assembly convenience of the inner shell and the outer shell, the overall structural strength and space layout of the product, and other factors.

[0027] Further, the top surface of the sleeve is provided with a recessed platform 11 recessed downward from the center of the inner layer sleeve hole of the inner shell 1. The size and shape of the recessed platform are designed to be just capable of embedding the bottom 22 of the rubber head of the dropper. Meanwhile, a groove 23 is arranged around the side surface of the bottom of the rubber head of the dropper. During assembly, the groove can be tightly engaged on the wall ring 15 of the inner layer sleeve hole by the appropriate deformation of the bottom of the rubber head of the dropper. In this way, the bottom of the rubber head of the dropper serves as a sealing ring of the inner layer sleeve hole of the sleeve, thereby playing a sealing role. Through the tight cooperation of the groove and the wall ring, the stability of the connection between the rubber head of the dropper and the sleeve is ensured, the phenomenon of shaking or separation of the dropper during use is effectively prevented, and the sealing performance of the entire cover body and the dropper combined structure is further improved, thereby effectively avoiding the problem of liquid leakage.

[0028] Based on the implementation of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
