Description

Technical Field

[0001] This utility model relates to the technical field of packaging hoses, specifically to a novel multi-layer cap hose. Background Technology

[0002] In today's consumer market, the packaging industry is experiencing rapid development. As consumers' living standards continue to improve, their demands for product user experience and functionality are becoming increasingly stringent. Cosmetic tubes, as indispensable containers in daily beauty and skincare, are widely used to hold various creams or liquids, such as face creams, lipsticks, hand creams, and various serums. These tubes typically consist of two parts: a tube body to hold the cosmetics and a cap to seal the tube body and prevent leakage.

[0003] When using a cosmetic tube, consumers should first unscrew the cap counterclockwise. Then, by squeezing the soft tube, the cosmetic product will flow smoothly from the nozzle and be applied to the skin. After use, the cap should be tightened clockwise back onto the tube to restore a seal, preventing air from entering and causing oxidation or spoilage, and also preventing accidental leakage that could stain clothes or bags.

[0004] Existing cosmetic tubes have a simple structure, and their structural strength is insufficient to withstand frequent opening and closing operations. Especially during forceful screwing of the cap, noticeable deformation often occurs at the connection between the tube body and the cap. Over time, this repeated deformation accumulates, leading to fatigue damage to the tube body and cap materials, which in turn affects the tightness of the threaded connection. Once the threaded fit loosens, the sealing performance of the cap is greatly reduced, allowing cosmetics to potentially leak from the tiny gaps between the tube head and the cap, causing unnecessary waste and possibly even staining the user's clothing or other items. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a novel multi-layer cap hose, which solves the problem that frequent opening and closing can easily lead to deformation and fatigue damage at the connection between the hose body and the cap, affecting the thread sealing performance and thus causing leakage.

[0006] To achieve the above objectives, this utility model provides a novel multi-layer cap hose, comprising a tube body, an inner cap, an outer cap, a locking assembly, and a leak-proof assembly. One end of the tube body is provided with a discharge nozzle. The inner cap is connected to the discharge nozzle, and the outer cap is fixedly connected to the inner cap. The locking assembly includes a buckle and a slider. The buckle is fixedly connected to the tube body and located on one side of the discharge nozzle. A groove is formed on the side of the inner cap, and the slider is slidably disposed within the groove. A locking block is fixedly disposed on the side of the slider and is connected to the buckle. The leak-proof assembly includes a sleeve and a pressure plate. The sleeve is fixedly disposed on the top of the inner cap and slidably connected to the discharge nozzle. The pressure plate is slidably disposed within the sleeve.

[0007] According to one embodiment of the present invention, the locking assembly further includes a first elastic element, which is fixedly disposed within a slide groove and located between the slider and the slide groove. The first elastic element includes a first spring, one end of which is connected to the slider, and the other end of which is connected to the slide groove. The first spring is made of stainless steel.

[0008] According to one embodiment of the present invention, the leak-proof assembly further includes a second elastic element disposed within the sleeve and located between the outer cover and the pressure plate. The second elastic element includes a second spring, one end of which is connected to the outer cover, and the other end of which is connected to the pressure plate. The second spring is made of stainless steel.

[0009] According to one embodiment of the present invention, the leak-proof assembly further includes a sealing gasket, which is fixedly disposed at the bottom of the pressure plate. The sealing gasket is made of rubber.

[0010] According to one embodiment of the present invention, a scale line is fixedly provided on the outer side of the tube body.

[0011] The advantages of this utility model compared to the prior art are:

[0012] The locking mechanism, with its snap-fit ​​and slider mechanism, effectively prevents deformation and fatigue damage at the connection between the tube body and the cap due to frequent opening and closing, maintaining thread sealing. Simultaneously, the pressure plate abuts against the discharge nozzle, eliminating leakage. The multi-layer cap structure also enhances overall sealing and protection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5 As shown, a novel multi-layer cap hose includes a tube body 1, an inner cap 2, an outer cap 3, a locking component 4, and a leak-proof component 5. One end of the tube body 1 is provided with a discharge nozzle 6. The inner cap 2 is connected to the discharge nozzle 6, and the outer cap 3 is fixedly connected to the inner cap 2. The locking component 4 includes a buckle 7 and a slider 8. The buckle 7 is fixedly connected to the tube body 1 and is located on one side of the discharge nozzle 6. The inner cap 2 has a sliding groove 9 on its side, and the slider 8 is slidably disposed in the sliding groove 9. A locking block 10 that is connected to the buckle 7 is fixedly disposed on the side of the slider 8. The leak-proof component 5 includes a sleeve 11 and a pressure plate 12. The sleeve 11 is fixedly disposed on the top of the inner cap 2 and is slidably connected to the discharge nozzle 6. The pressure plate 12 is slidably disposed in the sleeve 11.

[0024] In use, first push the slider 8 to disengage the locking block 10 from the buckle 7, thus releasing the lock. Then open the outer cover 3 and the inner cover 2, allowing the material inside the tube 1 to flow out from the outlet 6. After use, close the inner cover 2 and the outer cover 3, and push the slider 8 to engage the locking block 10 with the buckle 7 to lock it in place. In the closed state, the pressure plate 12 abuts against the outlet 6 to prevent material leakage.

[0025] By using the latch 7 and slider 8 of the locking component 4, deformation and fatigue damage at the connection between the tube body 1 and the tube cap due to frequent opening and closing can be effectively prevented, maintaining the thread seal. At the same time, the pressure plate 12 abuts against the discharge nozzle 6, solving the leakage problem. The multi-layer cap structure also enhances the overall sealing and protection.

[0026] refer to Figure 5 As shown, in some specific embodiments, the locking assembly 4 further includes a first elastic element 13, which is fixedly disposed within the slide groove 9 and located between the slider 8 and the slide groove 9. The first elastic element 13 includes a first spring, one end of which is connected to the slider 8, and the other end of which is connected to the slide groove 9. The first spring is made of stainless steel.

[0027] When slider 8 is pushed, the first spring is compressed, and the locking block 10 moves. After slider 8 is released, the first spring returns to its original state, and pushing slider 8 causes the locking block 10 to automatically reset and engage with the latch 7, achieving automatic locking. The first spring makes locking and unlocking operations more convenient, the automatic reset function enhances the stability of the lock, and the stainless steel first spring is durable and rust-resistant, extending its service life.

[0028] refer to Figure 5 As shown, in some specific embodiments, the leak-proof component 5 further includes a second elastic element 14, which is disposed within the sleeve 11 and located between the outer cover 3 and the pressure plate 12. The second elastic element 14 includes a second spring, one end of which is connected to the outer cover 3, and the other end of which is connected to the pressure plate 12. The second spring is made of stainless steel.

[0029] When the outer cover 3 and the inner cover 2 are closed, the outer cover 3 compresses the second spring, which pushes the pressure plate 12 downward to press the discharge nozzle 6, enhancing the sealing effect. The second spring provides continuous pressure, making the pressure plate 12 fit tightly against the discharge nozzle 6, further improving the leak-proof performance. The stainless steel second spring ensures long-term stable elasticity.

[0030] refer to Figure 5As shown, in some specific embodiments, the leak-proof component 5 further includes a sealing pad 15, which is fixedly disposed at the bottom of the pressure plate 12. The sealing pad 15 is made of rubber. Under the action of the second spring, the pressure plate 12 is pressed downwards, and the sealing pad 15 comes into contact with the discharge nozzle 6. Utilizing the high elasticity and sealing properties of rubber, it fills gaps and prevents material leakage. The rubber-made sealing pad 15 has good flexibility and sealing performance, effectively preventing material leakage from the discharge nozzle 6, further improving the leak-proof effect.

[0031] refer to Figure 1 As shown, in some specific implementations, a scale line 16 is fixedly provided on the outer side of the tube body 1. The scale line 16 intuitively displays the remaining amount of material in the tube body 1, which makes it convenient for users to accurately grasp the usage of the material in the tube, avoid the impact of insufficient material on use, and improve the convenience of use.

[0032] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be explained in conjunction with specific application scenarios:

[0033] When the user needs to use the cosmetic, pushing the slider 8 compresses the first spring, disengaging the locking block 10 from the buckle 7, easily releasing the lock. Then, opening the outer cover 3 and inner cover 2 allows the lotion or cream inside the tube 1 to be squeezed out from the nozzle 6. After use, closing the inner cover 2 and outer cover 3 and releasing the slider 8 restores the first spring to its original state. Pushing the slider 8 then engages the locking block 10 with the buckle 7, achieving automatic locking. This prevents frequent opening and closing of the tube 1 and the tube cover connection from causing deformation or damage, maintains thread sealing, and avoids leakage that could affect product quality.

[0034] In the closed state, the outer cover 3 compresses the second spring, which pushes the pressure plate 12 downward to press the dispensing nozzle 6. The rubber sealing pad 15 at the bottom of the pressure plate 12 contacts the dispensing nozzle 6, using the high elasticity and sealing properties of the rubber to fill gaps and prevent cosmetic leakage. The multi-layered cover structure also better protects the cosmetic from external contamination. The scale lines 16 on the outside of the tube 1 allow users to clearly see the remaining amount of cosmetic and make reasonable purchasing plans.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
