Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, and in particular to a passive pressurized cosmetic bottle. Background Technology

[0002] Liquid cosmetics, as a common everyday cosmetic product, are widely used for facial skin correction and skin tone evening. Currently, the packaging containers for liquid cosmetics on the market mainly include pump dispensers, squeeze tubes, and cushion compacts, with pump dispensers being the most common. This type of structure typically relies on a spring-loaded pump or pneumatic system to draw and dispense the liquid, but it has the following drawbacks:

[0003] Firstly, in actual use, users often need to press the pump multiple times to obtain the appropriate amount of cosmetic liquid. Moreover, the pump head structure is complex and prone to problems such as poor liquid dispensing, blockage, or rebound failure due to internal spring fatigue, poor sealing, or insufficient suction, which affects the user experience.

[0004] Secondly, because cosmetic liquids have certain oil-water separation characteristics, users often need to shake the bottle to mix the liquid evenly before use. However, in existing devices, the shaking operation and the dispensing operation are independent and not effectively combined, which means that users need to complete multiple steps to achieve normal use, making the operation cumbersome and inefficient.

[0005] In addition, pump-press bottles often have a large residual liquid area at the bottom that is difficult to suck out, resulting in liquid waste; and for the reuse or refilling of packaging bottles, most existing products do not have a convenient reset or refill structure, which limits the service life and lacks environmental protection and economy. Utility Model Content

[0006] The purpose of this invention is to provide a passive pressurized cosmetic bottle to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A passive pressurized cosmetic bottle includes a bottle body; a liquid outlet disposed on the upper part of the bottle body; a climbing rod fixedly disposed inside the bottle body; a piston plate slidably disposed on the climbing rod, with a storage chamber for cosmetic liquid above the piston plate; and a passive oscillating pressurizing component disposed below the piston plate, the passive oscillating pressurizing component being connected to the climbing rod. When the bottle is shaken, the passive oscillating pressurizing component vibrates, which can drive the piston plate to move upward along the climbing rod, pushing the cosmetic liquid in the storage chamber out of the liquid outlet.

[0008] Preferably, the passive oscillation pressurization assembly includes a climbing member disposed at the bottom of the piston plate and eccentric members disposed on both sides of the climbing member; the climbing member includes a climbing frame slidably sleeved on the climbing rod, and a fixing block inclinedly disposed in the climbing frame, one end of the fixing block being rotatably connected to the climbing frame, and the other end abutting against the climbing rod; the fixing block is elastically connected to the climbing frame through a spring rod to achieve unidirectional limiting of the fixing block.

[0009] Preferably, the passive oscillation pressurization component is provided with a reset component, the reset component including a sliding sleeve that is slidably sleeved on the climbing rod, and a connecting rod connecting the sliding sleeve and the fixed block.

[0010] Preferably, the connecting rod is L-shaped.

[0011] Preferably, a valve is provided on the liquid outlet for sealing the liquid outlet.

[0012] Preferably, the bottom of the bottle body is provided with a bottom cap.

[0013] Preferably, the bottle body is transparent.

[0014] The beneficial effects of this utility model are:

[0015] The piston plate rises with the structure to the bottom of the bottle, which can fully push out the liquid in the storage chamber. Compared with the traditional pump head structure, there is less residual liquid and more complete liquid output, which meets the design requirements of modern cosmetic packaging for high utilization rate and environmental protection and economy.

[0016] Cosmetic liquids usually need to be mixed by shaking the bottle before use. Taking advantage of this user habit, while shaking the bottle, the eccentric component rotates and drives the climbing mechanism to pressurize the inside of the bottle, eliminating extra steps and improving the convenience and natural and smooth user experience.

[0017] By using passive oscillation to drive the eccentric component to rotate periodically, each oscillation only causes the piston to move up slightly, achieving gradual release and controllable propulsion of liquid, avoiding waste caused by pushing out too much at once, and is suitable for cosmetic scenarios with precise usage requirements.

[0018] Users can manually release the self-locking state through the reset structure at the bottom of the bottle, allowing the piston plate and climbing mechanism to descend and reset smoothly. This facilitates the repeated use or refilling of the passively pressurized cosmetic bottle, enhancing the practicality and environmental friendliness of the device. Attached Figure Description

[0027] like Figures 1 to 4 As shown in the specific embodiment of this utility model, a passive pressurized cosmetic bottle includes a bottle body 100, a liquid outlet 101, a climbing rod 105, a piston plate 106, and a passive oscillating pressurization assembly 107. The bottle body 100 is generally cylindrical, with a liquid outlet 101 at its top for discharging the cosmetic liquid stored inside the bottle body. The climbing rod 105 is vertically fixed inside the bottle body 100 along its central axis. The piston plate 106 is slidably sleeved on the climbing rod 105, located between the climbing rod 105 and the bottle body 100, and a storage cavity 103 for storing the cosmetic liquid is formed above the piston plate 106. The outer edge of the piston plate 106 is in close contact with the inner wall of the bottle body 100, and a flexible sealing ring or elastic lip structure is used to achieve liquid sealing and prevent leakage of the cosmetic liquid during the climbing process. The passive oscillation pressurization component 107 is located below the piston plate 106 and connected to the climbing rod 105. By driving the passive oscillation pressurization component 107, the piston plate 106 can be moved upward along the climbing rod 105, thereby pushing the cosmetic liquid above the piston plate 106 to be discharged through the liquid outlet 101.

[0028] A passive oscillating pressurization assembly 107 is disposed below the piston plate 106 and is used to drive the piston plate 106 to move upward along the climbing rod 105. The passive oscillating pressurization assembly 107 includes a climbing member 107a and an eccentric member 107b;

[0029] The climbing component 107a includes a climbing frame 107a-1, a fixing block 107a-2, and a spring rod 107a-3 that is elastically connected. The climbing frame 107a-1 is a ring-shaped structure that is slidably sleeved on the outside of the climbing rod 105, allowing it to move up and down on the climbing rod 105 and serving as the support for the climbing component 107a. Eccentric components 107b are respectively provided on the left and right sides of the climbing frame 107a-1. The rotation axis of the eccentric component 107b is connected to the climbing frame 107a-1, allowing it to rotate under external force, thus periodically generating an upward or downward movement tendency through the eccentric structure. A fixing block 107a-2 is provided in the middle of the climbing frame 107a-1. This fixing block 107a-2 is inclined in the vertical direction, with one end hinged to the climbing frame 107a-1 via a rotating shaft, and the other end used to contact the surface of the climbing rod 105 to form a unidirectional limiting structure. The middle part of the fixed block 107a-2 is elastically connected to the inner side of the climbing frame 107a-1 via a spring rod 107a-3. One end of the spring rod 107a-3 is fixed to the fixed block 107a-2, and the other end is fixed to the inner wall of the climbing frame 107a-1, which is used to provide a reset elastic force for the fixed block 107a-2. In actual operation, when the eccentric part 107b rotates and generates an upward thrust, the climbing frame 107a-1 moves upward accordingly. Under the action of the thrust, the fixed block 107a-2 rotates clockwise around the hinge end, overcoming the elastic force of the spring rod 107a-3, thereby temporarily disengaging from the climbing rod 105, causing the climbing frame 107a-1 to drive the piston plate 106 to move upward as a whole. Conversely, when the eccentric component 107b continues to rotate and generates a downward thrust, although the climbing frame 107a-1 tends to move downward, due to the inclined setting of the fixed block 107a-2 and its inability to rotate counterclockwise, under the restoring force of the spring rod 107a-3, its end is in close contact with the climbing rod 105, thereby preventing the climbing frame 107a-1 from moving downward, thus playing a self-locking role in locking the position and preventing slippage.

[0030] The reset assembly 108 includes a sliding sleeve 108a and a connecting rod 108b. The passive oscillating pressurizing assembly 107 is equipped with the reset assembly 108 to restore it to its initial position after reaching the top of the bottle, facilitating refilling or reuse. The sliding sleeve 108a is a ring structure that slides around the outside of the climbing rod 105, allowing it to move up and down along the climbing rod 105. One end of the connecting rod 108b is connected to the sliding sleeve 108a, and the other end passes through the climbing frame 107a-1 and connects to the fixing block 107a-2, used to transmit displacement under external force, causing the fixing block 107a-2 to disengage from the climbing rod 105. Once the passive oscillating pressurizing component 107 has completed its operation and moved to the top of the bottle, the operator can pull the connecting rod 108b from the bottom of the bottle 100. This causes the fixed block 107a-2 to rotate counterclockwise around its rotating end, overcoming the elasticity of the spring rod 107a-3 and temporarily disengaging its end from the climbing rod 105, thus releasing the one-way limiting state. At this time, the passive oscillating pressurizing component 107 can fall back under external force, such as manual pressing or gravity, causing the piston plate 106 to descend to its initial position, achieving reset.

[0031] The connecting rods 108b are symmetrically arranged in an L-shape to effectively achieve synchronous control of the two fixed blocks 107a-2. In this embodiment, there are two fixed blocks 107a-2, located on the left and right sides of the climbing frame 107a-1, respectively; correspondingly, two connecting rods 108b are provided, each connecting rod 108b having one end connected to the sliding sleeve 108a, and the other end passing through the climbing frame 107a-1 and connecting to its respective fixed block 107a-2. The connecting rods 108b are arranged in a symmetrical L-shape, with their horizontal portions connected to the sliding sleeve 108a and their vertical portions connected to the two fixed blocks 107a-2 respectively. This structural design allows the sliding sleeve 108a to be pulled by an external force applied from the bottom of the bottle. The two L-shaped connecting rods 108b act simultaneously on the two fixed blocks 107a-2, causing them to rotate counterclockwise around the rotating end in sync. This overcomes the elastic effect of the spring rod 107a-3, causing the contact end of the fixed block 107a-2 to temporarily disengage from the surface of the climbing rod 105, thereby releasing the one-way limiting state.

[0032] A valve 102 is provided on the outlet 101 for controlling its opening and closing. Pressing the valve 102 opens or closes the outlet 101. When the valve 102 is closed, it effectively prevents the cosmetic liquid from flowing out of the outlet 101, avoiding leakage during transportation or when not in use. Furthermore, when the user pressurizes the bottle, the cap can be closed. In this case, shaking drives the eccentric component 107b to rotate, which in turn causes the climbing component 107a to oscillate. The passive oscillation pressurization assembly 107 moves upward as a whole, applying upward pressure to the piston plate.

[0033] A bottom cap 104 is detachably connected to the bottom of the bottle body 100. The bottom cap 104 is used to collect any cosmetic liquid that may leak from the bottom of the bottle body, preventing liquid spillage and environmental pollution. The bottom cap 104 is preferably connected to the bottle body 100 by threads for easy disassembly and cleaning. During use, if a small amount of cosmetic liquid seeps down the inner wall of the bottle body due to a loose fit between the outer edge of the piston plate 106 and the inner wall of the bottle body 100, the bottom cap 104 can promptly collect the leaked liquid, preventing liquid waste and contamination of the bottom of the bottle.

[0034] The bottle body is made of transparent material, allowing users to easily see the remaining amount of cosmetic liquid inside, making it convenient to refill or replace it in a timely manner. This transparent structure not only enhances the user experience but also facilitates liquid level monitoring during daily use, preventing the product from being affected by running out of liquid.

[0035] Working principle: During use, the cosmetic liquid inside the bottle is stored in the storage cavity 103 above the piston plate 106. The user shakes the bottle to rotate the eccentric parts 107b located on both sides of the passive oscillating pressurizing component 107. During the rotation of the eccentric parts 107b, an upward thrust is periodically generated, causing the climbing frame 107a-1, which is slidably set on the climbing rod 105, to move upward. At this time, the fixed block 107a-2, which is inclined and set in the climbing frame 107a-1, rotates clockwise under the elastic action of the spring rod 107a-3, temporarily releasing its contact with the climbing rod 105. The climbing frame 107a-1 can then drive the piston plate 106 connected to it to move upward as a whole, and the piston plate 106 squeezes the contents of the bottle.

[0036] As the eccentric component 107b continues to rotate, causing the climbing frame 107a-1 to move downwards, the fixed block 107a-2 is tilted so that its end contacts the climbing rod 105 and forms a self-locking mechanism, preventing the passive oscillation pressurization component 107 from sliding down. This ensures that each upward movement has a gradual propulsion effect, opening the valve 102 on the liquid outlet 101. The eccentric component 107b rotates, generating upward thrust multiple times, causing the cosmetic liquid in the bottle to be released gradually, avoiding excessive release at once and resulting in waste.

[0037] In addition, when it is necessary to reset the piston plate 106 and the passive oscillation pressurization assembly 107 to the initial position, the user can operate the L-shaped connecting rod 108b connected to the fixed block 107a-2 from the bottom of the bottle. By pulling the connecting rod 108b between the sliding sleeve 108a and the fixed block 107a-2, the two fixed blocks 107a-2 will rotate counterclockwise around their rotating ends at the same time, overcoming the elastic force of the spring rod 107a-3, and causing its end to temporarily detach from the surface of the climbing rod 105, thereby releasing the self-locking state and allowing the entire passive oscillation pressurization assembly 107 to move downwards smoothly to reset.

[0038] To enhance the user experience, a valve 102 is provided at the dispensing port 101 to seal it and prevent the cosmetic liquid from evaporating or becoming contaminated. Simultaneously, a bottom cap 104 is located at the bottom of the bottle body 100 to collect any cosmetic liquid that leaks due to a poor seal between the piston plate 106 and the inner wall of the bottle, keeping the bottle clean. The bottle body is made of a transparent material, allowing users to easily check the remaining liquid level and improving ease of use.
