Description

Technical Field

[0001] This utility model relates to the technical field of press-type cosmetic bottles, and in particular to a lever-type press-type cosmetic bottle. Background Technology

[0002] Cosmetics refer to chemical industrial products or fine chemical products that are applied to any part of the human body surface, such as skin, hair, nails, lips, and teeth, by means of smearing, spraying, or other similar methods, to achieve the purpose of cleaning, maintaining, beautifying, modifying and changing appearance, or correcting body odor and maintaining a good condition. Cosmetic packaging materials are divided into main containers and auxiliary materials. The main containers usually include plastic bottles, glass bottles, tubes, and vacuum bottles.

[0003] Currently, the main rebound mechanism of cosmetic bottle pump cartridges is a spring. The spring is typically installed between the valve stem and bushing of the pump cartridge, or on the outer wall of the pressing column. When the pump cartridge is pressed, the spring is compressed, storing elastic potential energy, and liquid is pumped out. After releasing the pressure, the spring releases its elastic potential energy, generating an upward force that pushes the valve stem and other components back to their original position. Simultaneously, it drives the piston and other components to move, coordinating with the opening and closing of the valve cartridge to control the intake and discharge of liquid, completing the entire rebound process. Springs are generally made of metal, requiring assembly inside the pump cartridge, increasing assembly difficulty and manufacturing costs. Furthermore, after the lotion in the cosmetic bottle is used up, most users simply discard the bottle, making it impossible to recycle the metal spring, resulting in resource waste. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a lever-type press cosmetic bottle with a simple structure, low manufacturing cost and automatic pump head rebound through a lever structure.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a bottle body, a pump cap threaded to the bottle body, a connecting tube snapped to the middle of the pump cap, an absorption tube slidably connected to the connecting tube, and a pressing head connected to the upper part of the connecting tube. A connecting channel is formed in the middle of the pump cap and snapped to the connecting tube. A support column is provided on the upper part of the pump cap and guides the absorption tube. A plurality of connecting plates are provided on the upper surface of the pump cap. The first end of each connecting plate is connected to the support column. A sealing plate is formed on the upper part of the connecting channel and connected to the inner wall of the pump cap. Each support column is fixedly connected to the sealing plate. The thickness of the first end of each connecting plate is greater than the thickness of the second end of the connecting plate.

[0006] Furthermore, each of the aforementioned support columns is disposed in the middle of the connecting plate.

[0007] Furthermore, the upper part of the connecting channel is formed with a groove that engages with the connecting pipe, and the upper part of the groove is formed with a retaining edge that limits the connection of the connecting pipe.

[0008] Furthermore, the lower part of the absorption tube is formed with a liquid-absorbing ring that is adapted to the inner wall of the connecting tube, the upper part of the liquid-absorbing ring is fitted with a piston that fits tightly against the inner wall of the connecting tube, and the middle part of the absorption tube is formed with a retaining ring that cooperates with the limiting position of the support column.

[0009] Furthermore, the connecting tube includes a sleeve, an extension tube, and a plug bead. The sleeve is engaged with the connecting channel, the extension tube is connected to the lower end of the sleeve, the plug bead is disposed at the lower end of the sleeve, and a buckle is formed on the upper part of the sleeve, which is engaged with the groove.

[0010] Furthermore, a tightening opening is formed at the lower end of the sleeve, the lower part of the tightening opening is connected to the extension tube, the upper part of the tightening opening is supported and engaged with the plug bead, and a number of protrusions are formed inside the sleeve to limit the maximum rising distance of the plug bead.

[0011] The beneficial effects of this utility model are as follows: Because this utility model uses a connecting plate in conjunction with a support column to form a lever structure, with the second end of the connecting plate connected to the support column, when the user presses down on the pressing head, the second end of the connecting plate bends downwards under force, the absorption tube moves downwards, the piston squeezes downwards, the pressure inside the bottle increases, and liquid flows out from the pressing head. When the pressing head is released, the connecting plate, under the action of the rebound force, lifts the absorption tube back to its original position. At this time, the volume inside the sleeve increases, forming a negative pressure. The plug bead opens under the action of the negative pressure, and the liquid in the bottle enters the sleeve. The overall structure is compact and easy to use. The lever structure formed by the support plate provides the support column with a restoring force. The overall structure is simple and easy to use, eliminating the need for an additional spring to provide the restoring force, thus improving installation efficiency while effectively reducing production costs.

A sealing plate 24 is formed on the upper part of the connecting channel 21, connecting to the inner wall of the pump cover 2. Each support column 22 is fixedly connected to the sealing plate 24. The thickness of the first end of each connecting plate 23 is greater than the thickness of the second end of the connecting plate 23. The cap 2 is made of a plastic material with good plasticity and elasticity. It uses a connecting plate 23 and a support column 22 to form a lever structure. The second end of the connecting plate 23 is connected to the support column 22. When the user presses down the pressing head 5, the second end of the connecting plate 23 bends downward under force, the absorption tube 4 moves downward, the piston 42 squeezes downward, the pressure inside the bottle 1 increases, and liquid flows out from the pressing head 5. At this time, the pressing head 5 is released, and the connecting plate 23 pushes the absorption tube 4 back to its original position under the action of the rebound force. At this time, the internal volume of the sleeve 31 increases, forming a negative pressure. The plug bead 33 opens under the action of the negative pressure, and the liquid in the bottle 1 enters the sleeve. The overall structure is compact and easy to use. The lever structure formed by the support plate provides the support column 22 with the support force for resetting. The overall structure is simple and easy to use. There is no need to provide the rebound force for resetting through an additional spring, which improves the installation efficiency and effectively reduces the production cost.

[0020] In this embodiment, each of the support columns 22 is disposed in the middle of the connecting plate 23, and the support column 22 disposed in the middle provides stable support force.

[0022] In this embodiment, the upper part of the connecting channel 21 is formed with a groove 25 that engages with the connecting pipe 3, and the upper part of the groove 25 is formed with a retaining edge 26 that limits the connection of the connecting pipe 3.

[0023] In this embodiment, the connecting pipe 3 includes a sleeve 31, an extension pipe 32, and a plug bead 33. The sleeve 31 is engaged with the connecting channel 21. The extension pipe 32 is connected to the lower end of the sleeve 31. The plug bead 33 is disposed at the lower end of the sleeve 31. A buckle 34 is formed on the upper part of the sleeve 31. The buckle 34 is engaged with the groove 25. The plug bead 33 is made of glass.

[0024] In this embodiment, the lower end of the sleeve 31 forms a tightening port 35, the lower part of the tightening port 35 is connected to the extension tube 32, the upper part of the tightening port 35 is supported and engaged with the plug bead 33, and a plurality of protrusions 36 are formed inside the sleeve 31 to limit the maximum rising distance of the plug bead 33.

[0025] The working principle of this utility model:

[0026] When the user presses down the pressing head 5, the second end of the connecting plate 23 bends downward under force, the absorption tube 4 moves downward, the piston 42 squeezes downward, the pressure inside the bottle body 1 increases, and liquid flows out from the pressing head 5. At this time, the pressing head 5 is released, and the connecting plate 23 pushes the absorption tube 4 back to its original position under the action of the rebound force. At this time, the internal volume of the sleeve 31 increases, forming a negative pressure. The plug bead 33 opens under the action of the negative pressure, and the liquid in the bottle body 1 enters the sleeve.

[0027] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
