Description

Technical Field

[0001] This utility model relates to the field of cosmetic technology, and specifically to a novel type of soft tube. Background Technology

[0002] Cosmetics are used to enhance, preserve, or alter a person's appearance (e.g., for performance purposes). Cosmetics come in various types, such as tubes. A tube consists of a tube body and an outer cap. One end of the tube body is open, and pressure applied to the tube body allows the product to flow out through the opening for application. However, during transportation, the tube body may be subjected to stress, or due to the viscosity of the product itself (low viscosity means high flowability), product may leak from the opening. Therefore, a baffle is usually installed at the opening after the tube is manufactured to prevent this. However, once the tube is used, the baffle must be removed. If the user then carries the tube in a bag, contact with other objects or the viscosity of the product may cause leakage. Summary of the Invention

[0003] The purpose of this utility model is to provide a one-way discharge hose, which is equipped with a valve core with a gap. Therefore, a certain force is required to open the gap. Vibration or slight touch during transportation cannot force the gap to open, thereby preventing material leakage. At the same time, compared with the baffle, the valve core is always inside the main body, so there will be no material leakage during use, thus solving the problem of material leakage.

[0004] The purpose of this utility model is achieved as follows:

[0005] A novel flexible hose includes a body, with a chamber for placing material in the middle of the body, a discharge port communicating with the chamber and for discharging material at one end of the body, and an opening communicating with the chamber at the other end of the body.

[0006] The main body has a built-in valve body, which is located on the side of the discharge port. The valve body includes a mounting base and a valve core. The valve core is set on the mounting base and is integrally injection molded with the mounting base. The valve core is elastic and is used to block the material from flowing out. The valve core has a slit, and the inner wall of the slit opens under force, allowing the material in the chamber to flow to the discharge port.

[0007] Preferably, the gap is in the shape of a straight line, a cross, or a star.

[0008] Preferably, the mounting base has a mounting hole in the middle, and the valve core is located inside the mounting hole.

[0009] Preferably, the main body is provided with an installation ring on the discharge port side, and the valve body is located inside the installation ring;

[0010] The inner wall of the mounting ring is provided with protrusions for restricting the mounting base;

[0011] Or / and, the outer side of the mounting base is provided with a protruding edge, and the inner wall of the mounting ring is provided with a mounting groove corresponding to the protruding edge.

[0012] Preferably, it also includes a cover, and the cover is connected to the end of the main body with the discharge port, and the cover is provided with a retaining post corresponding to the discharge port, so as to restrict the material from coming out by the retaining post being located inside the discharge port.

[0013] Preferably, one end of the main body is provided with a guide portion, and the guide portion has a discharge port at the end away from the main body. The guide portion also has a channel for connecting the discharge port and the chamber, and a cover is fitted on the outside of the guide portion and connected to the outer wall of the guide portion.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0015] This invention features a valve core with a slit, requiring a certain force to open. Therefore, vibrations or slight impacts during transportation will not force the slit to open, preventing material leakage. Furthermore, unlike a baffle plate, the valve core remains entirely within the main body, preventing material leakage during use. The mounting base and valve core are integrally injection molded, making installation easier and reducing gaps between them, thus improving sealing. Attached Figure Description

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-6 As shown, a novel hose includes a main body 1, with a chamber 11 for placing material in the middle of the main body 1, and a discharge port 12 communicating with the chamber 11 and used for discharging material at one end of the main body 1, and an opening communicating with the chamber 11 at the other end of the main body 1.

[0027] Meanwhile, the main body 1 has a built-in valve body 2, and the valve body 2 is located on one side of the discharge port 12. The valve body 2 includes a mounting base 21 and a valve core 22. The valve core 22 is set on the mounting base 21 and is integrally injection molded with the mounting base 21. The valve core 22 is elastic and is used to block the material from flowing out. The valve core 22 has a slit 221, and the inner wall of the slit 221 is opened by force, so that the material in the chamber 11 flows to the discharge port 12.

[0028] The opening allows the valve body 2 and the material to enter the chamber 11, and the opening can be heat-sealed to achieve connection and sealing. The mounting base 21 and the valve core 22 are integrally injection molded, specifically using a two-color injection molding process with hard and soft rubber; that is, the mounting base 21 is made of hard rubber, and the valve core 22 is made of soft rubber. Furthermore, the structure between the mounting base 21 and the valve core 22 is such that a mounting hole 211 is formed in the center of the mounting base 21, and the valve core 22 is located within the mounting hole 211.

[0029] Therefore, in actual use, since a certain force is required for the gap 221 to open, vibrations or slight touches during transportation cannot force the gap 221 to open, thus preventing material leakage. Furthermore, compared to the baffle, the valve core 22 remains within the main body, so material leakage will not occur during use. Moreover, the mounting base 21 and the valve core 22 are integrally injection molded, making installation more convenient and reducing the gap between the mounting base and the valve core, thereby improving sealing.

[0030] like Figure 6 As shown, different materials have different viscosities, so the gaps 221 have different shapes corresponding to different viscosities. For example, the gap 221 is a straight line, or the gap 221 is a cross, or the gap 221 is a star shape.

[0031] At the same time, such as Figure 2 and Figure 3As shown, the structure between the valve body 2 and the main body 1 is as follows: First, the main body 1 is provided with an installation ring 13 on one side of the discharge port 12, and the valve body 2 is located inside the installation ring 13. The inner wall of the installation ring 13 is provided with a protrusion for limiting the mounting seat 21.

[0032] Furthermore, the outer side of the mounting base 21 is provided with a protruding edge 212, and the inner wall of the mounting ring 13 is provided with a mounting groove corresponding to the protruding edge 212.

[0033] Therefore, in actual use, the valve body 2 is placed on the main body 1 by matching the protrusion and / or the protruding edge 212 with the mounting groove, and the position of the valve body 2 is limited.

[0034] like Figure 1 and Figure 4 As shown, the present invention also includes a cover 3, and the cover 3 is connected to one end of the main body 1 with a discharge port 12. The cover 3 is provided with a retaining post 31 corresponding to the discharge port 12, and the retaining post 31 is located inside the discharge port 12.

[0035] Therefore, in actual use, the material can be restricted from flowing out by setting the clamp 31. So even if material flows out from the valve body 2, the clamp 31 will still restrict it, thus achieving double restriction and effectively preventing material leakage.

[0036] Meanwhile, a guide part 14 is provided at one end of the main body 1, and a discharge port 12 is provided at the end of the guide part 14 away from the main body 1. The guide part 14 is provided with a channel 15 for connecting the discharge port 12 and the chamber 11. The cover 3 is sleeved on the outside of the guide part 14 and connected to the outer wall of the guide part 14.

[0037] Therefore, in actual use, the guide part 14 is used to guide the material to the outlet 12, and the cover 3 and the guide part 14 are connected by threads.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
