[0001] This utility model relates to the field of cosmetic packaging container technology, and in particular to a piston cosmetic bottle. Background Technology
[0002] As people's living standards continue to improve, their demands for quality of life are also increasing. Both men and women pay great attention to skincare, which makes the cosmetics industry very popular. This has greatly boosted various industries related to the cosmetics industry. Cosmetic bottles are essential for the cosmetics industry, as most cosmetics are stored and filled in cosmetic bottles.
[0003] Most cosmetic bottles currently feature a press-button mechanism at the bottle opening, with a tube inside the bottle. Squeezing the mechanism dispenses the cosmetic. However, when the remaining cosmetic is low, squeezing the mechanism may not dispense any more product, resulting in waste. Utility Model Content
[0004] The purpose of this invention is to provide a piston-type cosmetic bottle to solve the technical problem in the prior art where, when the amount of cosmetic product remaining in the bottle is small, even after squeezing or pressing, the cosmetic product will not come out, resulting in waste. 。 The various technical effects of the preferred technical solutions among the many technical solutions provided by this utility model are described in detail below.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] This utility model provides a piston cosmetic bottle, including a bottle body, a piston, and a pushing structure. The bottom end of the bottle body is provided with an opening structure, the piston is located inside the bottle body and the outer wall of the piston is tightly fitted with the inner wall of the bottle body, and the pushing structure passes through the opening structure and is located inside the bottle body.
[0007] When an external force is applied to the pushing structure, the pushing structure can push the piston to move towards the top of the bottle.
[0008] Optionally, the piston is made of silicone.
[0009] Optionally, the piston is provided with an extension head.
[0010] Optionally, it also includes a base connected to the opening structure, the base being able to prevent the pushing structure from detaching from the bottle body.
[0011] Optionally, the pushing structure can be a manually pressed structure or a rotary structure.
[0012] Optionally, the pushing structure includes an outer sleeve, an annular plate, and an inner sleeve. The end of the outer sleeve is fixedly connected to the outer wall of the annular plate, and the inner sleeve is fixedly connected to the inner wall of the annular plate. The outer sleeve and the inner sleeve are both located on the same side of the annular plate, and the length of the inner sleeve is greater than the length of the outer sleeve.
[0013] Optionally, the inner sleeve is provided with ventilation holes.
[0014] Optionally, the bottle also includes a bottle cap, and the upper end of the bottle body is provided with a bottle mouth, which is threadedly connected to the bottle cap.
[0015] This utility model provides a piston-type cosmetic bottle. The bottom of the bottle has an opening structure, and the piston is located inside the bottle with its outer wall tightly fitted to the inner wall of the bottle. A pushing structure passes through the opening structure and is located inside the bottle. When cosmetics are needed, external force is applied to the pushing structure, causing it to move relative to the bottle. This pushes the piston towards the top of the bottle, squeezing out all the cosmetics inside. This results in almost no cosmetic residue remaining in the bottle, or very little residue. This solves the problem in existing technologies where, even after squeezing the pressing structure, cosmetics remain in the bottle when there is little residue, leading to waste. 。 Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0031] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0032] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] This utility model provides a piston cosmetic bottle, including a bottle body 1, a piston 2 and a pushing structure 3, wherein the bottom end of the bottle body 1 is provided with an opening structure, the piston 2 is located inside the bottle body 1 and the outer wall of the piston 2 is tightly fitted with the inner wall of the bottle body 1, and the pushing structure 3 passes through the opening structure and is located inside the bottle body 1.
[0034] When an external force is applied to the pushing structure 3, the pushing structure 3 can push the piston 2 towards the top of the bottle 1. This utility model provides a piston cosmetic bottle with an opening structure at the bottom of the bottle 1. The piston 2 is located inside the bottle 1, and its outer wall is tightly fitted to the inner wall of the bottle 1. The pushing structure 3 passes through the opening structure and is located inside the bottle 1. When cosmetics are needed, an external force is applied to the pushing structure 3, allowing it to move relative to the bottle 1. This pushes the piston 2 towards the top of the bottle 1, causing all the cosmetics inside the bottle 1 to be squeezed out by the piston 2. This results in almost no cosmetic residue inside the bottle 1, or very little remaining cosmetic. This solves the technical problem in the prior art where, even after squeezing the pressing structure, the cosmetics in the bottle will not come out when the remaining amount is small, leading to waste.
[0035] As an optional implementation, the piston 2 can be made of silicone, allowing the outer wall of the piston 2 to fit tightly against the inner wall of the bottle 1, thus preventing cosmetics from spilling out between the piston 2 and the bottle 1. The bottle 1 has a cylindrical structure with a hollow interior, used to hold the cosmetics.
[0036] As an optional implementation, the piston 2 is provided with an extension head 21, which can be inserted into the bottle opening 11 to squeeze out the cosmetics in the bottle opening 11 and avoid cosmetics residue at the bottle opening 11.
[0037] As an optional implementation, a base 4 is also included. The base 4 is connected to the opening structure and can restrict the pushing structure 3 from detaching from the bottle body 1. The base 4 provides a support function. The size of the opening is smaller than the size of the outer sleeve 31, so that the outer sleeve 31 cannot pass through the opening, thereby restricting the pushing structure 3 from detaching from the bottle body 1. The size of the opening is larger than the size of the inner sleeve 33, so that the inner sleeve 33 can pass through the opening.
[0038] As an optional implementation, the pushing structure 3 is a manually pressed structure, that is, the pushing structure 3 needs to be moved by manually pressing; or the pushing structure 3 is a rotating structure, that is, the pushing structure 3 needs to be moved by manually rotating.
[0039] As an optional implementation, the extrusion structure 3 includes an outer sleeve 31, an annular plate 32, and an inner sleeve 33. The end of the outer sleeve 31 is fixedly connected to the outer wall of the annular plate 32, and the inner sleeve 33 is fixedly connected to the inner wall of the annular plate 32. The outer sleeve 31 and the inner sleeve 33 are both located on the same side of the annular plate 32, and the length of the inner sleeve 33 is greater than the length of the outer sleeve 31. The annular plate 32 is located on the side closer to the piston 2, and the annular plate 32 will come into contact with the piston 2 when the cosmetic is extruded.
[0040] As an optional implementation, the inner sleeve 33 is provided with a vent hole 331. When an external force is applied to the pushing structure 3, the vent hole 331 can discharge the gas between the inner sleeve 33 and the piston 2, thereby reducing the effect of the gas pressure between the inner sleeve 33 and the piston 2 on the external force.
[0041] As an optional implementation, a bottle cap 5 is also included. A bottle mouth 11 is provided at the upper end of the bottle body 1, and the bottle mouth 11 is threadedly connected to the bottle cap 5. The bottle cap 5 includes a flip-top portion and a connecting portion. The threaded sleeve inside the connecting portion is threadedly connected to the outer wall of the bottle mouth 11. An extension port is provided on the outer top plate of the connecting portion. The interior of the bottle mouth 11 is connected to the interior of the extension port. The extension head 21 can extend into the extension port. One end of the flip-top portion is rotatably connected to one end of the connecting portion. The flip-top portion is a flip-top structure.
[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
