Description

Technical Field

[0001] This utility model relates to the production of cosmetics, and more particularly to a cosmetic bottle designed to prevent accidental pressure. Background Technology

[0002] In the cosmetic packaging industry, traditional press-type cosmetic bottles are widely used due to their convenience, but they have long suffered from technical problems such as accidental press leakage and cosmetic waste. In existing technologies, ordinary press pumps typically use a single spring structure, and the pressing stroke lacks significant resistance variation, leading to the following problems: during carrying, cosmetic bottles are easily subjected to external pressure or impact, such as friction or squeezing from items inside a backpack, causing the pump to be accidentally triggered and resulting in cosmetic leakage. Although existing cosmetic bottles have undergone some improvements, certain shortcomings still exist. For example, patent CN222428297U discloses a spray bottle with an anti-accidental press structure, but this spray bottle still has the following shortcomings in preventing accidental activation: it requires simultaneously gripping the bottle and pressing, which is particularly unfriendly to users with small hands, and prolonged use can easily lead to fatigue. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention aims to provide a cosmetic bottle designed to prevent accidental pressure. It solves the problems existing in current technology by employing a carefully designed pump body. When the locking block of the stage mechanism disengages from the locking groove of the slider, the resistance of the third spring must be overcome, creating a distinct "locking point." A greater force is required to continue pressing, thus triggering the pump to dispense liquid. Users can feel two distinct strokes when pressing the dispensing head; a greater force is required at the junction of the first and second strokes, while ensuring a smooth rebound. This significantly reduces accidental pressure during use and minimizes waste of cosmetics.

Detailed Implementation

[0030] The following will refer to the appendix in the example of this utility model. Figure 1 - Appendix Figure 11 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] This utility model provides a technical solution: a cosmetic bottle designed to prevent accidental pressure, comprising a bottle body 1, a cap 2 fixed to the upper end of the bottle body 1, a dispensing head 3 mounted on the cap 2, and a pump body 4 mounted at the lower end of the dispensing head 3. The bottle body 1 is used to store cosmetics and is the main container of the cosmetic bottle. The cap 2 is fixed to the upper end of the bottle body 1, serving to seal the bottle body 1 and support the dispensing head 3 and the pump body 4. The dispensing head 3 is used to squeeze the pump body 4, realizing the quantitative extrusion of cosmetics while ensuring the stability and accuracy of the dispensing process. The pump body 4, through the tight cooperation of various parts, pumps out the cosmetic liquid from the bottle body 1 and realizes the function of preventing accidental pressure. When the user presses the dispensing head 3, they can feel two distinct strokes. A greater force is required at the junction of the first and second strokes, reducing the occurrence of accidental pressure and ensuring a smooth rebound, effectively reducing the waste of cosmetics in the bottle.

[0032] The pump body 4 includes a housing 401 fixed to the lower end of the outlet head 3, a sealing ring 402 installed inside the housing 401, a first spring 403 installed at the lower end of the sealing ring 402, a stage mechanism 404 fixed at the lower end of the first spring 403, a squeezing tube 405 fixed to the lower end of the outlet head 3, a second spring 406 fixed at the lower end of the squeezing tube 405, a blocking ball 407 installed at the bottom of the housing 401, and an inlet tube 408 fixed at the bottom of the housing 401. The housing 401 provides installation space and protection for other parts of the pump body 4, making the internal structure of the pump body 4 compact and stable. During the downward pressing process, the sealing ring 402 prevents the cosmetic liquid from flowing out from the side, allowing it to flow out along the outlet head 3. During the rebound process, it keeps the inside of the pump body 4 sealed, drawing the cosmetic liquid into the pump body 4. The first spring 403 is used to reset the sealing ring 402. The stage mechanism 404, in conjunction with the squeezing tube 405, enables two distinct downward pressure stages, alerting the user to potential accidental pressure and preventing the cosmetic liquid from spraying out due to squeezing inside the backpack. The squeezing tube 405 is fixed to the lower end of the dispensing head 3, and a stage ball 4051 is provided on the lower side, cooperating with the stage mechanism 404 to achieve staged downward pressure. Simultaneously, the up-and-down movement changes the volume inside the pump body 4, enabling the cosmetic liquid to be squeezed out. The second spring 406 is used to reset the squeezing tube 405. The blocking ball 407 is installed at the bottom of the outer casing 401 and cooperates with the inlet pipe 408 to control the intake and outflow of cosmetics. The pump body 4 draws in and pumps out cosmetic liquid through the inlet pipe 408.

[0033] The dispensing head 3 includes a limiting tube 301 sleeved on the outside of the squeezing tube 405, a squeezing head 302 fixed on the upper end of the limiting tube 301, a fixing ring 303 fixed on the upper end of the bottle body 1, and a first limiting ring 304 fixed on the outside of the fixing ring 303. The lower end of the limiting tube 301 is connected to the squeezing tube 405, transmitting the force from the squeezing head 302 to drive the pump body 4 to move. The fixing ring 303 is installed on the cover 2, so that the entire pump body 4 and the dispensing head 3 are integrally installed on the cover 2. The first limiting ring 304 is used to limit the rotation of the limiting tube 301 to prevent it from driving the squeezing tube 405 to rotate and causing a deviation from the position of the stage mechanism 404.

[0034] The stage mechanism 404 includes a fixed shell 4041, a third spring 4042 installed inside the fixed shell 4041, and a slider 4043 installed outside the third spring 4042. The fixed shell 4041 is fixed inside the outer shell 401. The first stage is when the extrusion tube 405 moves downward and contacts the slider 4043. When the extrusion tube 405 continues to press down, it pushes the slider 4043 to squeeze the third spring 4042 inward. When the slider 4043 is flush with the fixed shell 4041, the extrusion tube 405 can continue to move downward.

[0035] The fixed housing 4041 has a conical locking block 4044 inside; the locking block 4044 is used to prevent the slider 4043 from sliding out of the fixed housing 4041.

[0036] The slider 4043 has a locking groove 4045 on its side, a stepped surface 4046 on its upper end, a first inclined surface 4047 on its lower end, and a second inclined surface 4048 on its lower end. The locking groove 4045 and the locking block 4044 work together to prevent the slider 4043 from sliding out of the fixed shell 4041. When the stepped surface 4046 contacts the stage ball 4051, it generates resistance to prevent the extrusion tube 405 from pressing down. When force is applied, the stage ball 4051 passes through the stepped surface 4046 and continues to move downward along the first inclined surface 4047. At the same time, the slider 4043 is pushed into the fixed shell 4041. The second inclined surface 4048 is used to allow the stage ball 4051 to pass through when the extrusion tube 405 rebounds, making its rebound smoother.

[0037] The outer casing 401 has a second limiting ring 4011 inside; the second limiting ring 4011 is used to fix the stage mechanism 404.

[0038] A stage ball 4051 is provided at the lower end of the side of the extrusion tube 405, and a first limiting groove 4052 is provided at the upper end of the side of the extrusion tube 405. The first limiting groove 4052 cooperates with the first limiting block 3011 to prevent the extrusion tube 405 from rotating and to prevent the stage ball 4051 from misaligning with the stage mechanism 404.

[0039] The limiting tube 301 has a first limiting block 3011 inside and a third limiting ring 3012 outside. A second limiting block 3013 is located at the upper end of the third limiting ring 3012. The first limiting block 3011 cooperates with the second limiting groove 3041 to prevent the limiting tube 301 from rotating, thereby preventing the extrusion tube 405 from rotating. The third limiting ring 3012 is used to limit the position of the limiting tube 301 when the extrusion tube 405 springs back, thereby limiting the springback position of the extrusion tube 405.

[0040] The first limiting ring 304 has a second limiting groove 3041 inside.

[0041] Working principle:

[0042] By squeezing the squeezing head 302, the squeezing tube 405 moves downward through the limiting tube 301. At this time, the stage ball 4051 contacts the stepped surface 4046. When the stepped surface 4046 contacts the stage ball 4051, it will generate resistance to prevent the squeezing tube 405 from pressing down. When the force is continued, the stage ball 4051 passes through the stepped surface 4046 and continues to move downward along the first inclined surface 4047. At the same time, the slider 4043 will be pushed into the fixed shell 4041. At this time, the third limiting ring 3012 drives the sealing ring 402 to move downward, the space inside the pump body 4 decreases, and the cosmetic liquid is pumped out.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
