Description

Technical Field

[0001] This utility model relates to the field of flexible tube packaging technology, and in particular to a soft-tip type flexible tube and a lipstick tube. Background Technology

[0002] Lip balm is a common personal care product, mainly used to moisturize and protect the lips, preventing dryness, peeling and cracking. Lip balm is usually stored in a tube with a hole on the top of the tube's connector, and the lip balm is squeezed out by squeezing the tube.

[0003] In the prior art, the connector that contacts the lip is usually made of the same or similar thermoplastic resin as the tube body, such as PP or PE. The connector and the tube body are integrally molded or separately molded and then hot-melted to form an integral structure. Existing PP or PE connectors have certain strength but poor flexibility due to their material properties, resulting in poor comfort and compatibility when applied to the lip.

[0004] On the other hand, even when the hose is not in use, the internal liquid may still leak out to the connector or even from the junction of the cap and the hose, causing leakage and causing inconvenience to the user. Utility Model Content

[0005] To address the aforementioned issues, this application provides a reasonably structured soft-tip tube and lipstick tube, thereby effectively utilizing the softness of the soft part to improve the fit with the lips, enhancing the user's comfort and experience during application.

[0006] The technical solution adopted in this utility model is as follows: A flexible head type hose, comprising: tube body; Locking component, which is fitted to the end of the tube body; The applicator head has a support portion pressed between the tube end face and the locking component, and the flexible portion of the applicator head extends outward from the locking component. The end cap is detachably mounted on the end of the tube and houses the applicator head inside.

[0007] As a further improvement to the above technical solution: It also includes a liquid outlet hole that runs through the end of the tube and the applicator head; the center of the end cap extends toward the liquid outlet hole to form a protrusion, the protrusion is adapted to the shape of the liquid outlet hole, and the protrusion extends into the liquid outlet hole.

[0008] The protruding end passes through the applicator head and extends into the end of the tube, where the protruding end blocks the liquid outlet.

[0009] The liquid outlet includes a tapered hole on the soft part of the applicator head, a through hole on the support part, and a through hole on the end of the tube body. The diameter of the liquid outlet is smallest at the through hole. The size of the protruding end is the same as the size of the through hole.

[0010] The tube body includes a tube body, the end of which extends sequentially through a transitional oblique section to form a first cylindrical section, a second cylindrical section, and a third cylindrical section. The opening end of the third cylindrical section is sealed and has a through hole for liquid discharge, constituting the end of the tube body. The diameter of the tube body, the first cylindrical section, and the second cylindrical section decreases sequentially. A groove is formed on the second cylindrical section. The locking component passes through the soft part of the applicator head and is fitted onto the first cylindrical section at the end of the tube body. The inner wall of the locking component extends inward to form a protrusion that matches the groove.

[0011] The third columnar part has an outer clamping part spaced apart along the circumferential direction on its circumferential wall surface, and an inner clamping part adapted to the outer clamping part is formed on the inner wall surface of the locking part. The fitting of the inner clamping part and the outer clamping part restricts the rotation of the locking part relative to the end of the tube.

[0012] The grooves and protrusions are either ring structures extending circumferentially, or corresponding multi-segment structures spaced apart circumferentially.

[0013] The outer circumferential wall of the locking component has an external thread, and the inner circumferential wall of the end cap has an internal thread. The end cap and the locking component are threadedly fitted together. The edge of the end cap facing the tube body is longer than the edge of the locking component facing the tube body, and the end cap encloses the locking component inside. The inner wall of the edge of the end cap is recessed to form a concave ring.

[0014] The locking component has a mounting hole on its end face for the soft part of the applicator head to pass through upwards. The diameter of the mounting hole is smaller than the size of the applicator head support, so that the support is mounted inside the locking component.

[0015] A lipstick tube, using any one of the above-described soft-tip type tubes.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This utility model uses a locking component to mount the applicator head to the end of the tube body. When in use, the soft part of the applicator head contacts the application area, such as when applying to the lips through the soft part. This effectively utilizes the softness of the soft part to improve the fit with the lips, thereby enhancing the user's comfort and experience during application. This utility model also has the following advantages: The applicator head consists of a support part and a flexible part. By pressing the support part between the locking component and the end face of the tube body, the reliability of the applicator head installation on the end face of the tube body is effectively ensured. Liquid inside the tube flows out through the outlet hole for application by the user. When not in use, the end cap is fitted to the end of the tube and the protrusion of the end cap extends into the outlet hole to block it, thereby preventing the liquid inside the tube from leaking out accidentally through the outlet hole and effectively reducing or even eliminating leakage. The locking component is secured by fitting the protrusion with the groove of the tube body. The fitting between the inner locking part of the locking component and the outer locking part of the tube body restricts their relative rotation, thereby effectively ensuring the reliable installation between the locking component and the tube body and the reliable installation of the applicator head at the end of the tube body.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, a flexible head type hose of this embodiment includes: tube body 1; Locking component 2 is fitted to the end of the tube body 1; Apply to head 3, as follows Figure 3 As shown, the support part 32 of the applicator head 3 is pressed between the end face of the tube body 1 and the locking part 2, and the soft part 31 of the applicator head 3 extends outward from the locking part 2. End cap 4 is detachably mounted on the end of tube body 1, and end cap 4 houses the applicator head 3 inside.

[0024] In this embodiment, the applicator 3 is fitted to the end of the tube body 1 using the locking component 2. When in use, the soft part 31 of the applicator 3 comes into contact with the application area, such as applying the product to the lips through the soft part 31. The softness of the soft part 31 is effectively utilized to improve the fit with the lips.

[0025] In this embodiment, the applicator head 3 is composed of a support part 32 and a flexible part 31. By pressing the support part 32 between the locking member 2 and the end face of the tube body 1, the reliability of the applicator head 3 installed on the end face of the tube body 1 is effectively guaranteed.

[0026] It also includes a liquid outlet hole that runs through the end of the tube body 1 and the applicator head 3; such as Figure 4 As shown, the center of the end cap 4 extends toward the liquid outlet to form a protrusion 41, which is adapted to the shape of the liquid outlet and extends into the liquid outlet.

[0027] In this embodiment, the liquid inside the tube 1 flows out through the liquid outlet hole for the user to apply. When not in use, the end cap 4 is fitted to the end of the tube 1, and the protrusion 41 of the end cap 4 extends into the liquid outlet hole to block the liquid outlet hole, thereby preventing the liquid inside the tube 1 from accidentally leaking out through the liquid outlet hole, effectively reducing or even avoiding leakage.

[0028] The end of the protrusion 41 passes through the applicator head 3 and extends into the end of the tube body 1. The protrusion 41 blocks the liquid outlet at the end of the tube body 1, thus blocking the liquid from the end of the tube body 1 and preventing liquid leakage from the tube body 1.

[0029] The liquid outlet includes a tapered hole 311 on the soft part 31 of the applicator head 3, a through hole 321 on the support part 32, and a through hole on the end of the tube body 1. The diameter of the liquid outlet is the smallest at the through hole. The end size of the protrusion 41 is consistent with the size of the through hole, for example, a clearance fit with consistent size and small tolerance range is adopted. In this way, while ensuring smooth liquid flow through the liquid outlet during use and ensuring performance, the liquid outlet can be reliably plugged into the tube body 1 by the fitting of the end cap 4 on the tube body 1 when not in use, through the protrusion 41.

[0030] like Figure 2 As shown, the tube body 1 includes a tube body, and the end of the tube body extends sequentially through a transitional inclined body 10 to form a first columnar portion 11, a second columnar portion 12, and a third columnar portion 14. The opening end of the third columnar portion 14 is sealed and has a through hole for liquid discharge, forming the end of the tube body 1. The diameter of the tube body, the first columnar portion 11, and the second columnar portion 12 decreases sequentially. A groove 13 is provided on the second columnar portion 12. The locking member 2 passes through the soft part 31 of the applicator head 3 and is fitted onto the first columnar portion 11 at the end of the tube body 1. The inner wall of the locking member 2 extends inward to form a protrusion 22 that matches the groove 13.

[0031] In this embodiment, the tube body 1 can adopt the conventional flexible tube structure characteristics, that is, a larger tube body is connected to a smaller end body by a transitional oblique body 10.

[0032] In this embodiment, by setting the groove 13 on the second columnar part 12 at the end of the tube body 1, when the locking part 2 is fitted onto the end of the tube body 1, the protrusion 22 of the locking part 2 is fitted into the groove 13, thereby realizing the quick and reliable installation of the locking part 2 at the end of the tube body 1.

[0033] The third columnar part 14 has an outer clamping part 15 spaced out along the circumferential direction on its circumferential wall surface, and an inner clamping part 21 adapted to the outer clamping part 15 is formed on the inner wall surface of the locking member 2. The fitting of the inner clamping part 21 and the outer clamping part 15 restricts the rotation of the locking member 2 relative to the end of the tube body 1.

[0034] In this embodiment, the locking component 2 is fixed by fitting the protrusion 22 with the groove 13 of the tube body 1. The relative rotation is restricted by the fitting between the inner locking part 21 of the locking component 2 and the outer locking part 15 of the tube body 1, thereby effectively ensuring the reliable installation between the locking component 2 and the tube body 1 and ensuring the reliable installation of the applicator head 3 at the end of the tube body 1.

[0035] In this embodiment, the outer clamping part 15 and the inner clamping part 21 can be multiple sets of concave and convex strip structures arranged circumferentially. The length direction of the strip in a single set of concave and convex strip structures is arranged along the axial direction of the locking member 2 and the tube body 1. As the locking member 2 is fitted onto the tube body 1, the concave and convex parts in the outer clamping part 15 and the inner clamping part 21 are respectively adapted to achieve fitting, thereby effectively preventing the locking member 2 from rotating relative to the tube body 1 after installation and ensuring installation reliability.

[0036] In one embodiment, such as Figure 2 and Figure 3 As shown, the groove 13 and the protrusion 22 are annular structures extending circumferentially. When the locking member 2 is fitted onto the end of the tube body 1, the protrusion 22 of the locking member 2 is fitted into the groove 13 of the tube body 1.

[0037] In another embodiment, the groove 13 and the protrusion 22 are corresponding multi-segment structures arranged at intervals along the circumference. When the locking member 2 is fitted onto the end of the tube body 1, each protrusion 22 of the locking member 2 is correspondingly fitted into each groove 13 of the tube body 1.

[0038] The outer circumferential wall of the locking component 2 is provided with an external thread 23, and the inner circumferential wall of the end cap 4 is provided with an internal thread 42. The end cap 4 is threadedly fitted with the locking component 2, so that the end cap 4 can be installed at the end of the tube body 1 when not in use.

[0039] In this embodiment, the edge of the end cap 4 facing the tube body 1 is longer than the edge of the locking member 2 facing the tube body 1. The end cap 4 encloses the locking member 2 inside, thereby effectively improving and ensuring the overall aesthetic appearance and consistency of the hose while achieving the sealing of the end of the tube body 1 by the end cap 4.

[0040] In this embodiment, the inner wall surface at the edge of the end cap 4 is recessed to form a concave ring 43, which ensures the reliability of the fit between the end cap 4 and the tube body 1.

[0041] In this embodiment, the inner wall surface of the end of the locking component 2 facing the tube body 1 is provided with an inner chamfer 24 to ensure that the locking component 2 and the tube body 1 fit together properly after installation.

[0042] The end face of the locking component 2 is provided with a mounting hole 25 for the soft part 31 of the applicator head 3 to pass through upward. The diameter of the mounting hole 25 is smaller than the size of the support part 32 of the applicator head 3, so that the support part 32 is mounted inside the locking component 2.

[0043] In this embodiment, by opening a mounting hole 25 on the locking member 2, the soft part 31 of the applicator head 3 can pass outward through the locking member 2, while the support part 32 cannot pass through the locking member 2, so that the applicator head 3 is reliably installed by the locking member 2 combined with the end of the tube body 1 via the support part 32.

[0044] In this embodiment, the soft part 31 of the applicator head 3 can be made of soft rubber or silicone material, so that the soft part 31 can effectively achieve and ensure the fit and adaptation with the applicator object, such as the lips, through deformation during application. Of course, other materials, such as sponge, can also be used for the soft part 31 of the applicator head 3 according to actual needs, as long as the fit and adaptation can be achieved through deformation.

[0045] A lipstick tube, using any one of the above-described soft-tip type tubes.

[0046] This invention uses a locking device to mount the applicator head to the end of the tube body, effectively utilizing the softness of the soft part of the applicator head to improve its compatibility with the lips, thereby enhancing the user's comfort and experience during application.

[0047] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0048] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
