Description

Technical Field

[0001] This utility model relates to the field of cosmetic technology, specifically to a valve-driven liquid dispensing device with a remaining volume indicator. Background Technology

[0002] Cosmetics can be categorized by dosage form: Liquids: facial cleansers, bath gels, shampoos, toners, perfumes, cleansing waters, makeup removers, serums, essences, etc.; Lotions: lotions, creams, hair conditioners, serums; Creams: face creams, foundation creams, shampoos, concealers, hair treatments, essence creams, makeup primers; Powders: face powder, talcum powder, loose powder, cleansing powder, setting powder; Blocks: pressed powder, blush powder, lipsticks, hair wax; Oils: makeup remover oils, body oils, hair oils, facial oils. Currently, cosmetics are generally stored in squeeze-type or press-type packaging bottles. When using cosmetics, the bottle is manually pressed or squeezed to change its shape, making it easy to squeeze out the cosmetics. Our company's proposed pneumatic vacuum replaceable packaging bottle, based on announcement number CN217576355U, features a large liquid output, ease of use, and suitability for medium to high viscosity substances. Its vacuum piston structure minimizes residue and isolates the product from air, extending shelf life. The bottle's simple structure eliminates the need for a conventional pump head, saving on packaging costs. The replaceable inner liner allows for the reuse of other components, promoting energy efficiency and environmental friendliness. The bottom-mounted outlet ensures convenient and hygienic use, avoiding the issue of liquid residue remaining on the bottle surface associated with conventional top-mounted pumps. However, during use, the bottle exhibits several issues: the rubber surface easily attracts dust, leading to discoloration over time; and the need to press down on the small hole with a finger is problematic. Some customers may not have carefully read the instructions, failing to do so, thus preventing the liquid from being expelled. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a valve-driven liquid dispensing device with a remaining volume indicator, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a valve-driven liquid dispensing device with a remaining volume indicator, comprising a first inner liner, the first inner liner being fitted inside a first bottle body, a first push cap being fitted on the top of the inside of the first bottle body, a first spring being fitted on the outer side of the top of the inside of the first bottle body, one end of the first spring being connected to the inner wall of the first bottle body, and the other end of the first spring being connected to the inner side of the first push cap, a first piston being provided inside the top of the first bottle body, a first one-way valve being provided inside the first piston, a plurality of second air holes being opened on the surface of the first piston, a first air hole being opened on the top of the first push cap, a second piston being provided inside the first inner liner, a scale display plate being placed inside the second piston, a spoon being provided on one side of the first bottle body, and a first shoulder sleeve being installed on the outer side of the first inner liner.

[0005] Optionally, a second air chamber is provided inside the second piston and outside the scale display plate, and a first air chamber is provided inside the first bottle body and below the first piston.

[0006] Optionally, a viewing window is embedded on the outer side of the first bottle body, a dividing line is provided on the scale display panel, and yellow and red fillers are respectively provided on the outer side of the scale display panel above and below the dividing line.

[0007] Optionally, the outer side of the first inner liner is provided with an anti-detachment groove, and the outer side of the first inner liner and the side of the anti-detachment groove are provided with a first anti-rotation rib. The inner side of the first shoulder sleeve is provided with a plurality of second anti-rotation ribs, and the inner side of the first shoulder sleeve and the space between the second anti-rotation ribs are provided with an anti-detachment rib. The surface of the first shoulder sleeve is fitted with a buckle.

[0008] Optionally, the inner side of the first bottle body is provided with an arc surface, and a locking point is installed on the inner side of the arc surface.

[0009] Optionally, a screw cap is snapped onto the outer side of the first inner liner.

[0010] Optionally, a first discharge port is provided at the bottom of the first inner liner, and a first sealing ring is provided on the inner side of the top of the first bottle body and on the outer side of the first piston.

[0011] This utility model provides a valve-driven liquid dispensing device with a remaining volume indicator, which has the following advantages:

[0012] 1. This pneumatically operated liquid dispensing device with a residual volume indicator, through the use of a pneumatic valve structure composed of a first spring, a second piston, and the first piston, can completely discharge the material in the first inner tank, achieving zero material residue. This avoids the problem that some customers are unfamiliar with the operation method when using existing products, resulting in failure to block the first air hole and thus being unable to push the material. It also avoids the problem that the soft rubber surface of existing products easily attracts dust and fades over time. When the first one-way valve fails, the first air hole can be blocked to push the material. By setting the first one-way valve and the second air hole, one-way sealing and air intake can be achieved, enabling rapid liquid dispensing.

[0013] 2. This valve-driven liquid dispensing device with remaining balance indication features a viewing window and a scale display panel. When the user looks at the first bottle from the side, if part of the liquid is yellow and part is red through the viewing window, it indicates that the liquid is about to run out and a new first inner liner needs to be prepared. If no yellow or red is visible when viewed from the side, it means that the first inner liner is still within the normal operating range. If all the liquid is red when viewed from the side, it means that the liquid has been completely used up and the first inner liner needs to be replaced. The user can also check the protrusion of the protrusion to understand the liquid usage. Through these two remaining balance display structures, the liquid usage status can be displayed.

[0014] 3. The air valve-driven liquid dispensing device with a remaining volume indicator features an integrated design of the first inner liner and the first shoulder sleeve. When replacing, the first inner liner and the first shoulder sleeve are replaced together, making the operation simpler and easier for consumers to replace quickly. The first shoulder sleeve and the first bottle body use a hidden screw fastener to achieve quick disassembly and assembly of the first inner liner, making the disassembly and assembly of the first inner liner convenient. By replacing the metal spring with a plastic spring, the recyclability of this cosmetic storage device can be improved, which can meet the requirements of environmental protection.

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0051] Example 1

[0052] Please see Figures 1 to 12 and Figure 17 This utility model provides a technical solution: a valve-driven liquid dispensing device with a remaining volume indicator, comprising a first inner liner 11, the first inner liner 11 being fitted inside a first bottle body 6, a first push cap 1 being fitted on the top of the inside of the first bottle body 6, a first spring 2 being fitted on the outer side of the top of the inside of the first bottle body 6, one end of the first spring 2 being connected to the inner wall of the first bottle body 6, and the other end of the first spring 2 being connected to the inner side of the first push cap 1, a first piston 3 being provided inside the top of the first bottle body 6, a first one-way valve 4 being provided inside the first piston 3, a plurality of second air holes 15 being opened on the surface of the first piston 3, a first air hole 14 being opened on the top of the first push cap 1, a second piston 10 being provided inside the first inner liner 11, a scale display plate 9 being placed inside the second piston 10, a spoon 7 being provided on one side of the first bottle body 6, and a first shoulder sleeve 12 being installed on the outer side of the first inner liner 11.

[0053] A second air chamber 17 is provided inside the second piston 10 and outside the scale display plate 9. A first air chamber 16 is provided inside the first bottle body 6 and below the first piston 3. A viewing window 8 is embedded on the outside of the first bottle body 6. A dividing line is provided on the scale display plate 9. Yellow and red fillers are provided above and below the dividing line on the outside of the scale display plate 9, respectively. A protruding post 53 is provided at the end of the second piston 10. An anti-detachment groove 26 is provided on the outside of the first inner liner 11. A first anti-rotation rib 25 is provided on the outside of the first inner liner 11 and on the side of the anti-detachment groove 26. A first anti-rotation rib 25 is provided on the inside of the first shoulder sleeve 12. A number of second anti-rotation ribs 28 are provided. Anti-detachment ribs 27 are provided on the inner side of the first shoulder sleeve 12 and between the second anti-rotation ribs 28. A buckle 29 is installed on the surface of the first shoulder sleeve 12. When the first inner liner 11 is replaced, the buckle 29 will have a self-lifting action along the arc surface 30. When it reaches the locking point 31, it will provide feedback on the position through the locking point 31. An arc surface 30 is provided on the inner side of the first bottle body 6. The locking point 31 is installed on the inner side of the arc surface 30. A screw cap 13 is snapped on the outer side of the first inner liner 11. A first discharge port 18 is opened at the bottom end of the first inner liner 11. A first sealing ring 5 is provided on the inner side of the top of the first bottle body 6 and outside the first piston 3.

[0054] In summary, this pneumatically operated liquid dispensing device with a remaining balance indicator operates as follows: Pressing the first button 1 presses the first one-way valve 4, which is then pressed against the inner surface of the first piston 3 by air pressure, closing the second air hole 15. This creates a sealed space in the first air chamber 16. The air pressure drives the second piston 10 downwards, expelling the material inside the first inner tank 11 through the first outlet 18, thus completing the liquid dispensing. Releasing the first button 1 causes the first spring 2 to return to its original position. Since the external air pressure is lower than the internal air pressure, the first one-way valve 4 opens, allowing the second air hole 15 to open and external air to enter the first air chamber 16. The air pressure in the first air chamber 16 returns to normal, and the first button 1 and the first piston 3 return to their original positions. Pressing the first button 1 again initiates the next cycle.

[0055] If a user looks at the first bottle 6 from the side and observes through the viewing window 8 that part of it is yellow and part of it is red, it means that the material is about to run out and a new first inner liner 11 needs to be prepared for use. If no yellow or red is seen when viewed from the side, it means that the first inner liner 11 is still within the normal range of use. If it is all red when viewed from the side, it means that the material has been completely used up and the first inner liner 11 needs to be replaced.

[0056] like Figure 32 As shown, under normal use, the material can be seen through the viewing window 8, such as... Figure 33 As shown, the remaining coloring material indicator area begins to appear when the material is almost used up. When the protrusion (53) protrudes from the first discharge port (18), it also reminds the consumer that the material is almost used up. Figure 34 As shown, the material is exhausted when the protrusion (53) is fully exposed, and red is seen through the perspective window 8.

[0057] When the first inner liner 11 needs to be replaced, open the screw cap 13, then rotate the first shoulder sleeve 12 to remove it, thereby taking the first inner liner 11 out of the first bottle body 6 through the first shoulder sleeve 12. Then, put the new first inner liner 11 into the first bottle body 6, tighten the first shoulder sleeve 12 to install the first inner liner 11 inside the first bottle body 6, and then close the screw cap 13. Due to the integrated design of the first inner liner 11 and the first shoulder sleeve 12, the first inner liner 11 and the first shoulder sleeve 12 can be replaced together, making the operation simpler and facilitating quick replacement for consumers. The first shoulder sleeve 12 and the first bottle body 6 are connected by a hidden screw cap 29, which enables quick disassembly and assembly of the first inner liner 11.

The air pressure drives the third air chamber 45 downward, thereby squeezing the material inside the bottle 38 through the second discharge port 40 to complete the liquid dispensing. Then, releasing the third button 32 causes the metal spring 52 to rebound, and the external air pressure becomes lower than the internal air pressure. The second one-way valve 34 is then opened, allowing the fourth air hole 41 to open and external gas to enter the fourth air chamber 46. The air pressure in the fourth air chamber 46 returns to normal, and the third button 32 and the fifth piston 35 return to their original positions. Pressing the third button 32 again initiates the next cycle.
