Description

Technical Field

[0001] This utility model relates to the field of packaging bottle technology, specifically a press-type pump cosmetic bottle. Background Technology

[0002] Currently, most liquid cosmetic products (such as foundation, serum, makeup remover, and liquid eyeshadow) use a pump dispenser. Traditional pumps typically have a mechanical piston and spring mechanism at the bottle opening; the user presses the pump head with their finger, which moves the piston to dispense the liquid. While this type of design is widely used, it still has the following shortcomings in practical use: First, traditional pump heads are mostly vertically pressable, requiring users to apply force directly with their thumb or forefinger. During operation, the other hand is often needed to stabilize the bottle, making it difficult to operate with one hand and resulting in poor ease of use. This is especially true in makeup scenarios, where users often need to hold the mirror with one hand and dispense the liquid with the other, making operation inconvenient.

[0003] Secondly, existing pump structures primarily rely on pistons to directly compress liquid for output. When the piston's sealing performance is insufficient or obstructed, uneven liquid distribution, backflow, or liquid residue can easily occur, affecting the stability of liquid use. Furthermore, the direct compression method involving piston sliding friction and spring action results in significant operational resistance, which can easily cause finger fatigue in frequent use scenarios, and also leads to low liquid output efficiency.

[0004] In summary, existing press-pump cosmetic bottles still have shortcomings in terms of ergonomic convenience and the high efficiency of positive pressure-assisted dispensing. There is an urgent need for a new type of press-pump cosmetic bottle that can combine one-handed operation with a gas-assisted positive pressure structure to improve the convenience, stability and comfort of dispensing cosmetic liquids. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is: a press-type pump cosmetic bottle, including a liquid storage bottle, a side plate, a pressurizing component and a liquid guiding cap.

[0007] The liquid storage bottle is used to store cosmetic liquids. Its upper and lower ends are respectively connected to the pressurization component and the liquid guide cap through threaded holes and threads for detachable installation, ensuring overall sealing and easy replacement.

[0008] Specifically, the design enables stable installation and sealed storage of the bottle, preventing liquid leakage.

[0009] In a preferred embodiment, the side plate is welded or glued to one side of the liquid storage bottle, and an inner flow tube is provided on its inner side. One end of the inner flow tube is connected to a liquid outlet, and the liquid outlet port is perpendicular to the surface of the pressurization component.

[0010] Specifically, the C-shaped side plate guides the flow of liquid, and users can press the pressurization component with the back of their hand to make the liquid flow directly from the nozzle to the back of their hand or palm, which is convenient and ergonomic.

[0011] In a preferred embodiment, the inner side of the liquid guide cap is provided with a one-way liquid outlet valve for unidirectionally guiding the liquid flow inside the storage bottle into the inner flow tube.

[0012] Specifically, this structure effectively prevents liquid backflow, ensuring the unidirectionality and stability of the liquid output.

[0013] In a preferred example, the pressurizing assembly includes a screw cap seat, a movable cap, and a return spring, wherein a piston ring is embedded in the inner side of the movable cap and slidably sleeved with the inner side of the screw cap seat.

[0014] The return spring is located inside the screw cap seat, with its top end abutting against the inner side of the movable cover, used to achieve the lifting and lowering reset of the movable cover. Both the screw cap seat and the movable cover have air holes on their surfaces, and a one-way air inlet valve is fixedly installed on the bottom surface of the movable cover to allow for one-way air introduction.

[0015] Specifically, this structure creates positive pressure inside the bottle when the movable cap is pressed down, pushing the liquid out. When the movable cap is reset, external air enters the liquid storage bottle through the air hole and one-way air inlet valve, restoring the air pressure and ensuring a continuous and stable output of liquid.

[0016] In a preferred example, the liquid storage bottle has a transparent or semi-transparent bottle structure.

[0017] Specifically, users can visually observe the remaining liquid level in the storage bottle, making it easy to replenish or replace it in a timely manner.

[0018] In a preferred embodiment, the outer periphery of the screw cap seat is provided with a limiting groove, which is a linear structure used to guide the movable cover to slide axially and limit its deflection.

[0019] Specifically, this structure ensures a stable movement trajectory for the moving cover, avoiding rotational errors during threaded installation or use.

[0020] In a preferred example, the return spring is either a helical spring or a rubber elastic element.

[0021] Specifically, this design provides reliable elastic support for the reset of the moving cover, ensuring the cyclic working performance of the pressurization component.

[0022] In a preferred example, both the one-way air inlet valve and the one-way liquid outlet valve are one-way valve body structures.

[0023] Specifically, this design ensures one-way flow of gas and liquid inside and outside the bottle, preventing liquid backflow and gas leakage, thus enhancing the system's sealing and reliability.

[0024] In a preferred example, one side of the side panel is provided with a hook or hanging hole structure, and the bottom surface is provided with an anti-slip pad or anti-slip texture.

[0025] Specifically, the design enhances the portability and stability of the cosmetic bottle, making it convenient for users to carry and ensuring that the bottle is placed stably on the table.

[0026] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, the side plate has an overall C-shaped structure, which conforms to ergonomic design and allows users to directly press the pressurizing component with the back of their hand or the back of their fingers, realizing the pressurization and liquid extraction operation with one hand. This reduces the inconvenience of traditional operation that requires the cooperation of both hands and greatly improves the convenience and comfort of use.

[0027] 2. This utility model adopts the working principle of positive pressure extrusion and gas propulsion. With the help of the pressurization component and the cooperation of the one-way air inlet valve and the one-way liquid outlet valve, the liquid is pushed out by the positive air pressure inside the bottle. Compared with the traditional press pump structure that directly relies on the mechanical piston to squeeze the liquid, it reduces the user's operating resistance and improves the overall user experience.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0031] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0032] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a press-type pump cosmetic bottle.

[0033] Combination Figures 1-5 As shown, the present invention provides a press-type pump cosmetic bottle, comprising: a liquid storage bottle 100, a side plate 200, a pressurizing component 300, and a liquid guide cap 400.

[0034] The liquid storage bottle 100 is used to store cosmetic liquids and can be transparent or semi-transparent, allowing users to easily observe the remaining liquid level. The top and bottom of the liquid storage bottle 100 are provided with threaded holes, which are used to detachably and securely connect to the pressurization component 300 and the liquid guide cap 400 via threaded engagement, ensuring overall sealing and easy replacement.

[0035] The side plate 200 is welded or glued to one side of the liquid storage bottle 100, and has an overall C-shaped structure, which can support the liquid storage bottle 100 from below and extend to the top of the bottle body. An internal flow tube 220 is provided on the inner side of the side plate 200, and one end of the internal flow tube 220 is connected to a liquid outlet 210. The liquid outlet 210 is located directly above the liquid storage bottle 100, and its port is perpendicular to the surface of the pressurization component 300 so that the liquid can be discharged when the inside of the bottle is pressurized.

[0036] A liquid guide cap 400 is installed at the lower end of the liquid storage bottle 100. It contains a one-way discharge valve 410 to direct the liquid flow from inside the liquid storage bottle 100 into the inner flow pipe 220 in a unidirectional manner, preventing backflow and ensuring the unidirectionality and stability of the liquid discharge process. Specifically, the liquid guide cap 400 penetrates the side plate 200 and connects to the bottom surface of the liquid storage bottle 100, with the outer periphery of the liquid guide cap 400 sealingly abutting against the inner side of the side plate 200.

[0037] The pressurizing assembly 300 is installed at the upper end of the liquid storage bottle 100 and includes a screw cap seat 310, a movable cap 320, and a return spring 330. The screw cap seat 310 has air holes 311 on its surface and a limiting groove on its outer periphery to guide the movable cap 320 in axial lifting and lowering and prevent its deflection. A return spring 330 is installed inside the screw cap seat 310, with its top end abutting against the inner side of the movable cap 320. When the movable cap 320 is pressed down, the return spring 330 is compressed to store elastic potential energy, providing a restoring force after the external force is released, causing the movable cap 320 to return to its initial position. The return spring 330 can be either a helical spring or a rubber elastic element.

[0038] A one-way air inlet valve 340 is fixedly installed on the bottom surface of the movable cover 320 to enable one-way gas introduction. A piston ring 321 is embedded in the inner side of the movable cover 320, and the piston ring 321 is slidably sleeved with the inner cavity of the screw cap seat 310 to maintain sealing and stability during the up-and-down movement of the movable cover 320. Through the air hole 311, outside air enters the interior of the liquid storage bottle 100 under the control of the one-way air inlet valve 340, thereby forming a positive pressure and air pressure recovery cycle during the pressing and resetting process.

[0039] During operation, the user presses the outer surface of the movable cap 320 with the back of their hand or fingers. As the movable cap 320 moves axially downward, it compresses the return spring 330 and pushes the gas inside the screw cap seat 310 into the liquid storage bottle 100, creating positive pressure inside the bottle. This causes the cosmetic liquid in the liquid storage bottle 100 to enter the inner flow tube 220 through the one-way outlet valve 410 in the liquid guide cap 400, and then be discharged through the outlet 210 to the back of the user's hand or palm, thus completing the liquid dispensing operation. After the user releases the pressure, the return spring 330 pushes the movable cap 320 back to its original position, the air pressure inside the screw cap seat 310 decreases, and the one-way air inlet valve 340 introduces outside air to replenish the air pressure inside the bottle, thereby completing the air pressure restoration process.

[0040] In this embodiment, the outer periphery of the screw cap seat 310 and the liquid guide cap 400 is provided with threads that match the threaded holes at the top and bottom of the liquid storage bottle 100, thereby ensuring the overall detachability and sealing.

[0041] In this embodiment, one side of the side panel 200 is provided with a hook or hanging hole structure, which makes it convenient for users to hang cosmetic bottles on the wall or cabinet; the bottom surface of the side panel 200 can also be provided with anti-slip pads or anti-slip textures to enhance stability when placed.

[0042] By combining the above structures, this utility model realizes the functions of single-handed pressing to extract liquid, positive pressure gas to assist in liquid ejection, and unidirectional liquid delivery, avoiding the problems of uneven liquid output and inconvenient operation of traditional pumps, and significantly improving the overall user experience.

[0043] Working principle and usage process of this utility model: The press-type pump cosmetic bottle of this utility model achieves unidirectional pressurized delivery of cosmetic liquid in the bottle by setting up a pressurizing component 300, a liquid guide cap 400, a side plate 200 and a liquid storage bottle 100, and can directly dispense the liquid from the back of the hand or other locations, making it convenient to use.

[0044] When not in use, the storage bottle 100 is used to hold cosmetic liquids. The bottle body can be transparent or semi-transparent, allowing users to easily observe the remaining amount. The upper and lower ends of the storage bottle 100 are respectively fixedly connected to the pressure assembly 300 and the liquid guide cap 400 via threads, ensuring the bottle body is sealed. The liquid guide cap 400 has a built-in one-way dispensing valve 410, which can prevent backflow or leakage of liquid inside the bottle, ensuring the liquid is stored in a sealed manner.

[0045] In use, the user presses the surface of the movable cap 320 of the pressurizing component 300 with the back of their hand or the back of their fingers. Under the action of external force, the movable cap 320 moves axially downward along the limiting groove on the surface of the screw cap seat 310, while compressing the return spring 330, pressurizing the gas in the internal cavity of the screw cap seat 310 and the movable cap 320 and introducing it into the liquid storage bottle 100. During this process, the one-way air inlet valve 340 at the bottom of the movable cap 320 prevents gas leakage. After the manual action is removed, the return spring 330 drives the movable cap 320 to return to its original position, creating a negative pressure inside the screw cap seat 310, the movable cap 320, and the internal cavity of the liquid storage bottle 100. External airflow is introduced into the interior of the liquid storage bottle 100 through the air hole 311 on the surface of the screw cap seat 310 and the one-way air inlet valve 340, restoring the internal air pressure.

[0046] Under the positive pressure inside the bottle caused by pressing the cap 320, the cosmetic liquid in the storage bottle 100 is compressed and guided into the inner flow tube 220 through the one-way outlet valve 410 inside the liquid guide cap 400, and then discharged through the outlet nozzle 210. Since the port of the outlet nozzle 210 is perpendicular to the surface of the pressurizing component 300, the liquid can be directly discharged onto the back of the user's hand or palm, making the operation intuitive and convenient.

[0047] During the pressure restoration process inside the bottle, the one-way discharge valve 410 effectively prevents the liquid inside the inflow tube 220 from flowing back into the storage bottle 100.

[0048] The side panel 200 has an overall C-shaped structure, which facilitates the fixing of the liquid storage bottle 100 and guides the arrangement of the inner flow tube 220. A hook or hanging hole can be provided on one side of the side panel 200 for easy hanging of cosmetic bottles on the wall or in the cabinet. The bottom surface of the side panel 200 is equipped with anti-slip pads or anti-slip texture to enhance stability when placed and prevent the bottle from slipping.
