Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic hoses, in particular to a cosmetic hose screw cap structure. Background Art

[0002] Cosmetic hose is a common form of cosmetic packaging. It has many advantages. First, its material usually has good flexibility and sealing properties, which can effectively protect cosmetics from external pollution and oxidation, ensuring the quality and stability of the product. For example, the material of common toothpaste tubes can prevent the volatilization of water and the deterioration of ingredients in cosmetics. Secondly, cosmetic hoses are easy to carry and use. Consumers can easily squeeze out the required amount of product, and can better control the amount squeezed out during use to reduce waste. For example, some liquid foundation hose packaging allows consumers to accurately obtain the right amount of liquid foundation.

[0003] After searching, the Chinese patent authorization number CN214127408U discloses a cosmetic hose, including: an inner tube body and an outer tube body, the inner tube body is fixedly connected with the outer tube body by a buckle, the head of the inner tube body is provided with a first outlet, the head of the outer tube body is provided with a second outlet, the head of the outer tube body is also equipped with a pipe mouth, the pipe mouth includes a first liquid outlet and a second liquid outlet, the first outlet is connected to the first liquid outlet, the second outlet is connected to the second liquid outlet, the first liquid outlet is located on the end face of the pipe mouth away from the inner tube body, the second liquid outlet is located on the side wall of the pipe mouth, the outer side wall of the inner tube body close to one end of the pipe mouth is provided with a limit piece, and correspondingly, the outer side wall of the outer tube body close to one end of the pipe mouth is provided with a limit groove. The above patent has the following deficiencies: after the use of the existing cosmetic hose, the cap is tightened and then placed. However, sometimes the user is too anxious or other factors prevent the cap from being tightened thoroughly, resulting in poor sealing of the cosmetic concentrate in the hose. Especially when the cosmetic hose is placed in a suitcase, if the cap is not tightened and the hose is placed upside down, the cosmetics may easily leak and squeeze onto the surface of clothes, causing great inconvenience. Moreover, if the cap is not tightly sealed for a long time, the cosmetics may deteriorate faster, and the cap and the cosmetic hose may not be automatically and effectively sealed.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] Reference Figure 1-Figure 8 A cosmetic hose screw cap structure comprises a cosmetic hose 1 and a screw cap 2, wherein a threaded extruder head 3 is fixedly connected to the top of the cosmetic hose 1, and a receiving groove 4 is provided on the bottom surface of the screw cap 2. The structure also comprises: a threaded sleeve 5 fixedly connected to the receiving groove 4; a fixed cylinder 6 fixedly connected to the top inner wall of the receiving groove 4; a cylindrical airbag bag 7 arranged in the fixed cylinder 6; an extrusion rod 8 slidably connected in the fixed cylinder 6; a sealing airbag ring 9 arranged at the bottom of the screw cap 2, and a delivery pipe 10 is arranged between the sealing airbag ring 9 and the cylindrical airbag bag 7. When the cosmetic hose 1 is in use, the screw cap 2 is turned to drive the threaded sleeve 5 to rotate on the threaded extruder head 3 to unscrew it. After use, the screw cap 2 is covered on the cosmetic hose 1 and the screw cap 2 is rotated in the opposite direction to drive the threaded sleeve 5 to rotate. While the threaded sleeve 5 rotates, the extrusion rod 8 can be driven to contact the surface of the cosmetic hose 1. Then the extrusion rod 8 slides into the fixed tube 6 and squeezes the cylindrical air bag 7 at the same time, and the gas in the cylindrical air bag 7 is squeezed into the delivery tube 10. At this time, the screw cap 2 and the cosmetic hose 1 are already fitted together, and the gas in the cylindrical air bag 7 enters the sealing air bag ring 9, so that the sealing air bag ring 9 is expanded to fill the gap between the screw cap 2 and the cosmetic hose 1, thereby increasing the sealing between the screw cap 2 and the cosmetic hose 1. It is difficult for the cosmetic stock solution to leak out even if it is squeezed. Even if the tightening force of the screw cap 2 is not enough, the sealing air bag ring 9 can be expanded to expand and seal it.

[0029] The outer surface of the threaded extruder 3 is provided with a thread groove, which is threadedly connected to the threaded sleeve 5, and the outer surface of the screw cap 2 is fixedly provided with an anti-slip sleeve 201. The anti-slip sleeve 201 on the outside of the screw cap 2 helps to increase the friction between the palm and the screw cap 2 when the screw cap 2 is screwed, reduces sliding, and helps to achieve a better tightening effect of the screw cap 2.

[0030] A circular groove is formed on the surface of the fixing tube 6 , and the top of the cylindrical airbag bag 7 is fixedly connected to the top inner wall of the circular groove of the fixing tube 6 .

[0031] A mounting groove is provided on the bottom surface of the rotary cover 2 , and the sealing airbag ring 9 is fixedly connected in the mounting groove of the rotary cover 2 .

[0032] The delivery pipe 10 passes through the fixing cylinder 6 and the containing groove 4 and is fixedly connected to the fixing cylinder 6 and the containing groove 4 . The delivery pipe 10 passes through the mounting groove of the rotary cover 2 and is fixedly connected to the mounting groove of the rotary cover 2 .

[0033] A spring 11 is sleeved on the surface of the extrusion rod 8, and a circular plate 12 is fixedly connected to the bottom of the extrusion rod 8. One end of the spring 11 is fixedly connected to the fixing tube 6, and the other end of the spring 11 is fixedly connected to the circular plate 12. When the extrusion rod 8 slides upward, the spring 11 is compressed. When the screw cap 2 is unscrewed, the elastic force of the spring 11 facilitates the quick unscrewing of the screw cap 2. At the same time, the spring 11 helps to automatically reset the extrusion rod 8.

[0034] A smooth ball block 13 is fixedly connected to the bottom of the circular plate 12. When the screw cap 2 is tightened, the extrusion rod 8 drives the circular plate 12 and the smooth ball block 13 to contact the surface of the cosmetic hose 1. The smooth ball block 13 can reduce the friction between the circular plate 12 and the cosmetic hose 1 when the screw cap 2 rotates, making the screw cap 2 rotate more smoothly.

[0035] There are two groups of cylindrical airbag bags 7, fixed tubes 6, conveying tubes 10, extrusion rods 8, springs 11, circular plates 12, and smooth ball blocks 13, and the two groups of cylindrical airbag bags 7, fixed tubes 6, conveying tubes 10, extrusion rods 8, springs 11, circular plates 12, and smooth ball blocks 13 are symmetrically arranged with the center line of the accommodating groove 4 as the axis of symmetry.

[0036] In the utility model, when using cosmetics, by rotating the screw cap 2, the threaded sleeve 5 is driven to rotate on the threaded extruder head 3, and the spring 11 plays an auxiliary role, so that the screw cap 2 is quickly unscrewed. When the screw cap 2 needs to be tightened, the screw cap 2 drives the threaded sleeve 5 to rotate, and at the same time drives the extrusion rod 8, the circular plate 12 and the smooth ball block 13 to contact with the surface of the cosmetic hose 1 and rotate with the screw cap 2. As the screw cap 2 rotates, the extrusion rod 8 slides upward into the fixed cylinder 6 to squeeze the cylindrical airbag bag 7, and the gas in the cylindrical airbag bag 7 enters the sealing airbag ring 9 through the delivery pipe 10, so that the sealing airbag ring 9 expands, fills the gap between the screw cap 2 and the cosmetic hose 1, and thus increases the sealing between the cosmetic hose 1 and the screw cap 2.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
