Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, specifically a cosmetic dispensing tube with sealing function. Background Technology

[0002] Existing cosmetic refill tubes typically employ a simple compression structure, which, while cost-effective, has several shortcomings in practical use: Firstly, traditional tubes lack an effective sealing mechanism, making it easy for contents to leak when not in use, resulting in waste and potential contamination of the packaging or the environment. Secondly, some tubes have inconveniently designed openings, requiring users to frequently unscrew or tighten the caps, which is inconvenient and prone to damage. Furthermore, some tubes are made of rigid materials, resulting in a poor squeezing experience and difficulty in completely expelling the contents, leading to significant residue.

[0003] Therefore, there is an urgent need in the market for a cosmetic refill tube that is simple in structure, easy to use, and can effectively seal the contents. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cosmetic dispensing tube with a sealing function, aiming to solve problems such as easy leakage, inconvenient sealing, and material defects of traditional tubes.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A cosmetic dispensing tube with sealing function includes a tube body, a tube head, and a tube cap. The tube body has an opening at the top, the tube head is detachably connected to the tube body at the opening, and the tube cap is fitted over the tube head and the top of the tube body.

[0007] The tube head includes a base and a rotating head. The base is used to connect with the tube body. The top of the rotating head is provided with a liquid outlet tube. A switch valve is provided at the connection between the rotating head and the base. The rotating head is rotatably connected to the base. By rotating the rotating head, the opening and closing of the switch valve is controlled.

[0008] As an improvement, the switch valve includes two valve plates arranged vertically, the two valve plates are fixedly connected to the rotating head and the seat respectively, and the two valve plates are rotatably connected by a rotating shaft located in the middle position;

[0009] The two valve plates have valve plate openings at corresponding positions.

[0010] As an improvement, the two valve plate openings have the same shape, the same size, and are positioned accordingly.

[0011] As an improvement, the base and the rotating head are provided with an indicator section for the valve plate to open and close the sealing pipe.

[0012] As an improvement, the instruction section located on the seat and the rotating head is respectively an instruction mark and an instruction arrow.

[0013] As an improvement, the top of the liquid outlet tube is provided with a ball head, and the ball head is provided with a liquid outlet.

[0014] As an improvement, the tube body is made of a flexible material and the bottom is heat-sealed.

[0015] The advantages of this utility model are:

[0016] 1. This utility model features a valve on the tube head, which can be sealed when not in use to effectively prevent leakage of contents and to prevent external air from entering the tube and causing oxidation of the cosmetics. This utility model can effectively extend the product's lifespan and reduce waste.

[0017] 2. The rotating head and base of this utility model feature a rotatable connection design, making opening and closing simple and quick, eliminating the need for frequent twisting of the tube cap. Combined with indicator marks and arrows, it provides intuitive guidance to the operator, reducing the risk of misoperation and effectively improving the user experience. The tube body is made of flexible material, making it easy to compress and providing a comfortable feel. The heat-sealed bottom enhances overall sealing and durability. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0026] Example 1:

[0027] like Figure 1 and Figure 2 As shown in the figure, this embodiment discloses a cosmetic dispensing tube with sealing function, including a tube body 1, a tube head 2, and a tube cap 3. The top of the tube body 1 has an opening 11, and the opening 11 has a threaded portion 12. The tube head 2 is detachably connected to the tube body 1 at the opening 11, specifically through a threaded connection. The tube cap 3 is fitted onto the top of the tube head 2 and the tube body 1, serving a dustproof and protective function.

[0028] like Figure 3 As shown, the tube head 2 includes a base 21 and a rotating head 22. The base 21 has an internal thread at its bottom, which is tightly screwed into the threaded part 12 to ensure a stable connection. The top of the rotating head 22 has a liquid outlet tube 23. A switch valve 4 is provided at the connection between the rotating head 22 and the base 21. The bottom of the rotating head 22 is sleeved on the outside of the base 21 and is smoothly rotated with the base 21 through a gear structure. By rotating the rotating head 22, the user can easily control the opening and closing of the switch valve 4, thereby controlling the outflow of contents.

[0029] like Figure 4 and Figure 5 As shown, the switch valve 4 consists of two valve plates 41 arranged vertically. The upper valve plate is fixedly connected to the rotating head 22, and the lower valve plate is fixedly connected to the base 21. The two valve plates 41 are flexibly rotatably connected by a rotating shaft 42 located in the middle. When the rotating head 22 is rotated, the upper valve plate rotates accordingly, while the lower valve plate remains stationary. The two valve plates 41 have valve plate openings 43 of the same shape and size, and precisely corresponding in position. When the valve plate openings 43 are aligned, the contents can pass through smoothly; when the valve plate openings 43 are misaligned, the valve closes, preventing the contents from flowing out.

[0030] To facilitate user identification of the valve's open / closed status, an indicator mark 51 is provided on the seat 21, and an indicator arrow 52 is provided on the rotating head 22. When the indicator arrow 52 aligns with the indicator mark 51, it indicates that the valve is in the open state; when the indicator arrow 52 deviates from the indicator mark 51, it indicates that the valve is in the closed state. The top of the outlet pipe 23 is provided with a ball head 6, on which multiple outlet ports 61 are evenly distributed, ensuring smooth liquid flow while effectively preventing the intrusion of dust and other foreign objects.

[0031] The tube body 1 is made of high-quality flexible material with good elasticity, making it easy for users to evenly squeeze out the contents while ensuring a comfortable user experience. The bottom of the tube body 1 is heat-sealed to form a sealed bottom structure, preventing contents from leaking out from the bottom and enhancing the overall sealing and durability of the hose.

[0032] This utility model features a simple structure and convenient operation, effectively solving the problems of easy leakage and inconvenient sealing in existing cosmetic dispensing tubes. It provides users with a practical and reliable cosmetic dispensing solution, especially suitable for the dispensing needs of travel-sized, trial-size, or small-volume cosmetics, and has broad application prospects in the cosmetic packaging field. The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on its technical solution and inventive concept, should be included within the scope of protection of this utility model.
