Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic packaging, and more specifically relates to a cosmetic packaging tube that is easy to use. Background Art

[0002] Among all kinds of cosmetic products, the container for holding cosmetic substances is indispensable. The existing cosmetic container structure is popular, traditional, and not novel in function. Different containers are required when using a variety of cosmetics. At present, traditional cosmetic products need to be taken out of the container and applied separately with hands or tools, which is not convenient to use and carry. In addition, when not in use, once the bottle body is touched or squeezed, the cosmetics in the bottle body will seep out from the liquid outlet, causing waste of cosmetics and contaminating the bottle head. With the wide variety of packaging containers, consumers have also put forward novel requirements for the use method. Utility Model Content

[0003] In view of the deficiencies of the prior art, the utility model provides a cosmetic packaging tube which is easy to use, has a simple structure, and is convenient to use and carry.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a cosmetic packaging tube that is easy to use, comprising an outer bottle and an inner bottle, the front end of the outer bottle is provided with a bottle head, an elastic pressing device that is connected to each other is provided between the inner bottle and the outer bottle, a brush head connected to the elastic pressing device is provided at the bottle head, a pressing end extending from the outer bottle is provided at the rear end of the inner bottle, and an anti-extrusion limiting structure is provided between the pressing end and the outer bottle.

[0005] The inner bottle, the outer bottle, the bottle head and the elastic pressing device form an infusion channel that is interconnected. The liquid is stored in the inner bottle. During use, the pressing end at the rear end of the inner bottle is pressed, and the liquid flows downward into the bottle head under the action of the elastic pressing device to reach the end, and can be applied using a brush head. When not in use, the inner bottle is locked and cannot be pressed by an anti-extrusion limiting structure, and the internal liquid will not flow out, thereby avoiding waste caused by the outflow of liquid due to accidental contact. The utility model has a reasonable structural design, and the front brush head can be used to facilitate and evenly achieve application without the need for hand contact or the use of other supporting tools, and is easy to use. When not in use, leakage can be avoided, and it is easy to carry.

[0006] Furthermore, the elastic pressing device includes a pump core fixed in the outer bottle, the end of the inner bottle is connected to a pump sleeve for the pump core to pass through, the inner bottle is provided with a liquid outlet pipe and a piston that cooperate with the pump core, and the pump core is provided with a return spring. The pump sleeve is fixed to the inner end, and one end of the pump core extends into the liquid outlet pipe. Under the action of pressing, the cosmetics in the bottle are transported to the front end through the liquid outlet pipe and the pump core. The return spring is sleeved on the pump core, one end of which contacts the pump sleeve, and can be pressed repeatedly and automatically return to its original position.

[0007] Furthermore, the anti-extrusion limiting structure includes limiting blocks arranged on both sides of the pressing end, and two grooves cooperating with the limiting blocks are arranged on the inner side of the outer bottle, and the two grooves are arranged one long and one short. The two grooves are arranged in parallel, and two groups are symmetrically arranged on both sides of the outer bottle. The grooves are opened in a long strip shape and arranged along the height direction of the outer bottle, and the width of the grooves is adapted to the limiting blocks. When it is needed to use, the inner bottle is rotated to the position of the limiting block in the long groove, and the inner bottle is pressed, and the limiting block can slide in the long groove; when it is not needed to use, the inner bottle is rotated to the position of the limiting block in the short groove, the limiting block is stuck, the inner bottle cannot be pressed, and the cosmetics in the bottle will not flow out. This structural design avoids the waste of cosmetics due to accidental contact during non-use, and is clean, hygienic and easy to carry.

[0008] Furthermore, a fixing seat for fixing the brush head is provided at the front end of the pump core, and the brush head is installed through the fixing seat and extends out of the bottle head through the bottle mouth. The brush head adopts a fixed structure with multiple fiber ends, and the fibers are clearly separated. The end of the brush head adopts a triangular cross-section with a long middle and two side ends. It is soft, elastic, soft and skin-friendly, which improves the comfort of use and improves the uniformity of makeup application.

[0009] Furthermore, the diameter of the bottle head gradually decreases along the outlet direction. The bottle head adopts a structure with a gradually decreasing diameter, so that after the fixing seat is installed into the bottle head from the rear end, it can be stuck in the bottle head to maintain the stability of the installation structure.

[0010] Furthermore, a bottle cap is connected to the bottle head of the outer bottle, and the bottle cap is snap-fitted with the outer bottle. A circle of slots is arranged inside the bottle cap, and a plurality of convex points are arranged on the bottle barrel. When in use, the bottle cap only needs to be pressed onto the bottle head to achieve connection, and it is not easy to fall off.

[0011] Furthermore, the inner bottle and the outer bottle are made of transparent PP material, and the pressing end of the inner bottle is made of anodized aluminum material. The inner bottle and the outer bottle are made of transparent PP material, which reduces the manufacturing cost and makes it easy to observe the use of the cosmetics inside; the anodized aluminum pressing end is high in hardness, corrosion-resistant, and not easy to wear, which improves the use performance.

[0012] In summary, the utility model sets a brush head on the bottle head and uses an elastic pressing device to control the liquid discharge, which is easy to operate. The utility model has a reasonable structural design and uses a front brush head to facilitate and evenly apply the liquid without the need to stain the bottle with hands or use other matching tools, which is easy to use. When not in use, it can avoid leakage and is easy to carry. BRIEF DESCRIPTION OF THE DRAWINGS
