Description

Technical Field

[0001] This application relates to the field of cosmetic packaging technology, and more specifically, to a cosmetic plastic bottle with a dispensing mechanism. 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 altering appearance, or correcting body odor and maintaining a good condition.

[0003] Traditional cosmetics are packaged in plastic bottles. Some lotion-type cosmetics are usually dispensed using a pump. Pumps are convenient to use as they dispense with a simple pressing action. However, the amount dispensed varies depending on the pressure applied, making it difficult to precisely control the amount dispensed. This often results in over-dispensing, leading to waste of cosmetics. In addition, accidental pressing can easily occur. Furthermore, when placed on a shelf, pumps lack a stable connection to the surface, making them prone to tipping over and falling, affecting the stability of use. Further improvements are possible.

[0004] To address the aforementioned issues, this application provides a cosmetic plastic bottle with a dispensing mechanism. Utility Model Content

[0005] The cosmetic plastic bottle with a metering dispensing structure provided in this application adopts the following technical solution: A cosmetic plastic bottle with a metering dispensing structure includes a bottle body and a pressure rod. A piston is slidably connected inside the bottle body, with its outer wall sliding against the inner wall of the bottle. The bottle body has a cylindrical structure, and the piston is a disc-shaped structure made of elastic material. A discharge port is connected through the bottom of the bottle body, coaxially arranged with the bottle body. A one-way valve is installed on the surface of the discharge port, pointing in the direction of cosmetic flow. A shelf is fixedly installed on the bottom of the bottle body, with a distance of at least 5cm between the bottom surface of the shelf and the bottom surface of the discharge port for easy hand insertion. A suction cup (of common design) is fixedly installed on the bottom surface of the shelf. A insert is fixedly installed on the top surface of the piston, coaxially arranged with the piston. A side ring and a support plate are fixedly installed sequentially from top to bottom on one side surface of the bottle body. The side ring stabilizes the pressure rod, and a socket is fixedly installed on the top surface of the support plate. A handle is fixedly installed on the top surface of the pressure rod for easy operation. The bottle body is transparent for easy observation, and graduations are printed on its outer surface.

[0006] The above technical solution uses a pressure rod to push the piston downward, which in turn squeezes the cosmetics located in the bottle below the piston. The cosmetics are then discharged through the outlet, completing the cosmetic dispensing process. Users can judge the volume of the extruded cosmetics by observing the alignment of the piston bottom with the scale, thus making it convenient for users to take out the cosmetics in the required quantity. Compared with the traditional press pump dispensing method, the dispensing is more accurate and reduces cosmetic waste.

[0007] Furthermore, the length of the pressure rod is greater than the internal height of the bottle body. The pressure rod is made of plastic round rod, and a through groove is opened on the top surface of the bottle body for the pressure rod to pass through, making it convenient for users to pass through the pressure rod.

[0008] With the above technical solution, the length of the pressure rod is greater than the internal height of the bottle, which makes it easier for the user to press the piston to fit the bottom surface of the bottle, thereby reducing cosmetic residue.

[0009] Furthermore, a compression sleeve is fixedly installed on the inner wall of the socket, and the inner diameter of the compression sleeve is smaller than the outer diameter of the pressure rod. The compression sleeve is made of an elastic material, such as rubber.

[0010] With the above technical solution, when the pressure rod is inserted into the extrusion sleeve, the extrusion sleeve is deformed by pressure and the pressure rod is fixed by its own elasticity, preventing the pressure rod from falling off at will, thus improving the stability of the pressure rod when not in use. Users can insert the pressure rod through the side ring into the socket and fix the pressure rod by the extrusion action of the extrusion sleeve, reducing the overall height of this application and making it convenient to carry.

[0011] Furthermore, the bottom surface of the pressure rod is provided with a bevel, the bevel is circumferentially formed, and the diameter of the bottom surface of the bevel is smaller than the inner diameter of the extrusion sleeve.

[0012] The above technical solution makes it easier for the bottom of the pressure rod to enter the extrusion sleeve, thus facilitating the insertion and connection by the user.

[0013] Furthermore, a sealing sleeve is fixedly connected through the piston surface. The sealing sleeve is made of rubber and has elasticity. A guide rod is vertically fixedly connected inside the bottle body. Multiple sets of guide rods are arranged, and the guide rods pass through the sealing sleeve and slide against the inner wall of the sealing sleeve.

[0014] Through the above technical solution, the sliding contact between the sealing sleeve and the guide rod provides friction, thereby preventing the piston from moving up and down arbitrarily and improving the stability of piston movement.

[0015] Furthermore, the suction cups are arranged in multiple sets, and the suction cups are distributed at the corners of the bottom surface of the display rack, with four suction cups in total.

[0016] Through the above technical solution, the display rack improves the stability of the display. The suction cups located on the bottom of the display rack can adhere to the table, further improving the stability of the display.

[0017] Furthermore, the inner diameter of the insert is larger than the outer diameter of the pressure rod, the insert has a cylindrical structure, the inner diameter of the side ring is larger than the outer diameter of the pressure rod, and the height difference between the side ring and the socket is not less than two-thirds of the length of the pressure rod.

[0018] Through the above technical solution, the insert tube facilitates the connection between the pressure rod and the piston, and the side ring stabilizes the upper part of the pressure rod, preventing the pressure rod from shaking randomly.

[0019] In summary, this application includes the following beneficial technical effects: The piston is pushed down by a pressure rod, squeezing the cosmetic inside the bottle below it. The cosmetic is then discharged through the outlet, completing the dispensing process. Users can judge the volume of cosmetic dispensed by observing the alignment of the piston's bottom with the scale, allowing for precise dispensing of the required amount. Compared to traditional pump-type dispensing, this method is more accurate and reduces waste. The pressure rod is removable; after removal, it can be inserted through the side ring into the socket, where it is secured by the squeezing sleeve, reducing the overall height of the device and making it easier to carry. Furthermore, the one-way valve on the outlet surface allows for unidirectional dispensing; the cosmetic cannot be dispensed when the piston is not pressing, eliminating the need for frequent capping and improving usability. Additionally, the shelf enhances stability; suction cups on the bottom of the shelf adhere to the table, further improving stability. Attached Figure Description

[0025] Example:

[0026] This application discloses a cosmetic plastic bottle with a dispensing structure. Please refer to [link / reference]. Figure 1 and Figure 2The device includes a bottle body 1 and a pressure rod 5. A piston 2 is slidably connected inside the bottle body 1, with its outer wall sliding against the inner wall of the bottle body 1. The bottle body 1 has a cylindrical structure, while the piston 2 has a disc-shaped structure and is made of elastic material. A discharge port 13 is connected through the bottom surface of the bottle body 1, coaxially arranged with the bottle body 1. A one-way valve 14 is installed on the surface of the discharge port 13, with the valve 14 positioned in the direction of cosmetic flow from the bottle body 1. The one-way valve 14 allows only unidirectional discharge; when the piston 2 is not pressing, the cosmetic cannot be squeezed out, eliminating the need for frequent capping and improving ease of use. A shelf 15 is fixedly installed on the bottom surface of the bottle body 1, with a distance of at least 5cm between the bottom surface of the shelf 15 and the bottom surface of the discharge port 13, facilitating hand insertion and easy retrieval. A suction cup 16 is also fixedly installed on the bottom surface of the shelf 15. The 16 is a common structure. A cylinder 11 is fixedly installed on the top surface of the piston 2. The cylinder 11 is coaxially arranged with the piston 2. A side ring 7 and a support plate 8 are fixedly installed on one side surface of the bottle body 1 from top to bottom. The side ring 7 is used to stabilize the pressure rod 5, and a socket 9 is fixedly installed on the top surface of the support plate 8. A handle 6 is fixedly installed on the top surface of the pressure rod 5. The handle 6 is convenient for users to operate. The bottle body 1 is a transparent structure for easy observation, and the outer surface of the bottle body 1 is printed with a scale 17. The piston 2 is pushed down by the pressure rod 5. The piston 2 moves down and squeezes the cosmetic located below the piston 2 in the bottle body 1. The cosmetic is discharged through the discharge port 13, completing the cosmetic discharge. Users can judge the volume of cosmetic squeezed out by observing the alignment of the bottom surface of the piston 2 with the scale 17, so that users can take out the cosmetic in the required amount. Compared with the traditional press pump dispensing, the dispensing is more accurate and reduces the waste of cosmetic.

[0027] Please see Figure 1 and Figure 3 The length of the pressure rod 5 is greater than the internal height of the bottle body 1. The pressure rod 5 is made of plastic round rod, and a through groove is opened on the top surface of the bottle body 1 for the pressure rod 5 to pass through. The through groove makes it convenient for the user to pass through the pressure rod 5. The length of the pressure rod 5 is greater than the internal height of the bottle body 1, which makes it easy for the user to press the piston 2 until the bottom surface is in contact with the bottom surface of the bottle body 1, thereby reducing cosmetic residue.

[0028] Please see Figure 1 and Figure 3 A compression sleeve 10 is fixedly installed on the inner wall of the socket 9. The inner diameter of the compression sleeve 10 is smaller than the outer diameter of the pressure rod 5. The compression sleeve 10 is made of elastic material, such as rubber. When the pressure rod 5 is inserted into the compression sleeve 10, the compression sleeve 10 is deformed by pressure and fixes the pressure rod 5 by its own elasticity, preventing the pressure rod 5 from falling off at will. This improves the stability of the pressure rod 5 when it is not in use. Users can insert the pressure rod 5 through the side ring 7 into the socket 9 and fix the pressure rod 5 by the compression action of the compression sleeve 10, thereby reducing the overall height of this application and making it easier to carry.

[0029] Please see Figure 1 The bottom surface of the pressure rod 5 is provided with a bevel 12. The bevel 12 is circumferentially opened, and the bottom diameter of the bevel 12 is smaller than the inner diameter of the extrusion sleeve 10. The bevel 12 facilitates the bottom of the pressure rod 5 to enter the extrusion sleeve 10, thereby making it convenient for the user to insert.

[0030] Please see Figure 1 and Figure 4 A sealing sleeve 3 is fixedly connected through the surface of piston 2. The sealing sleeve 3 is made of rubber and is elastic. A guide rod 4 is fixedly connected vertically inside the bottle body 1. Multiple sets of guide rods 4 are arranged, and the guide rods 4 pass through the sealing sleeve 3 and slide against the inner wall of the sealing sleeve 3. The sliding contact between the sealing sleeve 3 and the guide rod 4 provides friction, thereby preventing piston 2 from moving up and down at will and improving the stability of piston 2 movement.

[0031] Please see Figure 2 and Figure 3 Multiple sets of suction cups 16 are arranged, and the suction cups 16 are distributed at the corners of the bottom surface of the display rack 15. There are four suction cups 16, which improves the stability of the display rack 15. The suction cups 16 located on the bottom surface of the display rack 15 can adhere to the table, further improving the stability of the display.

[0032] Please see Figure 1 and Figure 2 The inner diameter of the insert 11 is larger than the outer diameter of the pressure rod 5. The insert 11 has a cylindrical structure. The inner diameter of the side ring 7 is larger than the outer diameter of the pressure rod 5. The height difference between the side ring 7 and the socket 9 is not less than two-thirds of the length of the pressure rod 5. The insert 11 facilitates the docking of the pressure rod 5 and the piston 2. The side ring 7 stabilizes the upper part of the pressure rod 5 and prevents the pressure rod 5 from shaking randomly.

[0033] The implementation principle of this embodiment is as follows: In use, the piston 2 is pushed down by the pressure rod 5. The piston 2 squeezes the cosmetics located in the bottle 1 below the piston 2. The cosmetics are discharged through the discharge port 13, completing the cosmetic discharge. The user can judge the volume of the squeezed cosmetics by observing the alignment of the bottom surface of the piston 2 with the scale 17, so that the user can take out the cosmetics in the required amount. Compared with the traditional press pump type dispensing, the dispensing is more accurate and reduces the waste of cosmetics. At the same time, the pressure rod 5 can be pulled out. After pulling out the pressure rod 5, the user can insert the pressure rod 5 through the side ring 7 into the socket 9. The pressure rod 5 is fixed by the squeezing action of the squeezing sleeve 10, reducing the overall height of this application and making it easier to carry. At the same time, the one-way valve 14 located on the surface of the discharge port 13 can only discharge in one direction. When the piston 2 is not squeezing, the cosmetics cannot be squeezed out, saving the user the trouble of frequently closing the cap and improving the convenience of use. In addition, the display rack 15 improves the stability of the display. The suction cup 16 located on the bottom surface of the display rack 15 can be attached to the table, further improving the stability of the display.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
