Description

Technical Field

[0001] The invention relates to the technical field of daily chemical packaging, in particular to a vacuum cream bottle. Background Art

[0002] Skin care creams are a type of emulsified product that has a skin care effect. According to their appearance, they can be divided into creams (soft texture) and ointments (hard texture); according to their oil content, they can be divided into vanishing creams, neutral creams (moisturizers) and balms; according to the emulsifier form, they can be divided into oil-in-water (O / W) type and compound emulsion type (W / O / W or O / W / O).

[0003] However, the existing cosmetic containers directly store the cream and then cover it with a lid. When using, the cream can be directly used after unscrewing the lid. However, when storing the cream in such containers, the cream is easily exposed to air, and long-term contact can easily cause the cream to undergo qualitative changes, thereby affecting the use experience of the cream.

[0004] In response to the above problems, the Chinese utility model patent with patent number CN201820889757.4 (publication number CN208360867U) discloses "A vacuum squeeze packaging bottle for cream skin care", including a vacuum packaging bottle and a push-type liquid suction structure, wherein a fixed block is threadedly connected to the vacuum packaging bottle, and a sealing cover is fixedly connected to the upper end of the fixed block. The push-type liquid suction structure consists of a liquid storage cylinder, a liquid guide tube, a liquid inlet valve, a spring, a piston, a liquid outlet pipe and an exhaust valve, and the lower surface of the fixed block is fixedly connected to the liquid storage cylinder.

[0005] The packaging bottle uses a pressing liquid suction structure to press the cream liquid in the vacuum packaging bottle out from the inside of the vacuum packaging bottle for use, without opening the bottle cap, thereby reducing the contact between the cream and the air. However, the pressing plate is arranged on the upper surface of the liquid outlet pipe. When pressing, the liquid outlet of the liquid outlet pipe may be easily blocked by the hand, causing inconvenience in liquid discharge. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a vacuum cream bottle with a liquid outlet and a button separately arranged in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a vacuum cream bottle, comprising

[0008] A bottle body, wherein the bottle body has a cavity inside which the space can always be filled with the cream, and the top of the cavity is open;

[0009] It is characterized by that it also includes

[0010] A pump seat, wherein the pump seat cover is arranged on the top of the chamber, a channel is provided on the pump seat, and a liquid outlet connected to the channel and an opening connected to the channel are provided on the top of the pump seat, the liquid outlet and the opening are arranged at intervals, and a liquid inlet connecting the channel and the chamber is provided at the bottom of the pump seat;

[0011] A first one-way valve is disposed at the liquid outlet and can move up and down to open or close the liquid outlet, wherein the first one-way valve only allows the material in the channel to flow out of the liquid outlet;

[0012] A valve core is arranged in the opening, the valve core can move downward relative to the opening under the action of an external force, and the valve core maintains a sealing connection with the inner peripheral wall of the opening;

[0013] A button is located above the opening, and the button is connected to the valve core through a valve stem;

[0014] The elastic member acts on the valve core to keep the valve core moving upward.

[0015] In order to further improve the sealing performance in the chamber and ensure that the cream is not contaminated, a second one-way valve is also provided at the liquid inlet. The second one-way valve can move up and down relative to the liquid inlet to cover or open the liquid inlet. The second one-way valve only allows the substance in the chamber to flow into the channel.

[0016] In order to prevent the cream from being contaminated by the elastic member when flowing into the channel, the elastic member is arranged outside the channel, and the elastic member acts on the button to keep the button always in a tendency to move upward.

[0017] In order to limit the upward movement of the valve core and prevent the valve core from moving out of the opening under the action of the elastic member, a flange that can abut against the upper end of the valve core is formed on the inner wall of the opening. When the valve core abuts against the flange, the valve core cannot continue to move upward.

[0018] In order to facilitate the installation of the pump seat and to position the pump seat, the bottle body is provided with a step for the pump seat to rest on, the step is the top wall of the bottle body or is formed on the inner circumferential wall of the bottle body and is arranged adjacent to the top of the bottle body, and a cover body is threadedly connected to the top of the bottle body, and the cover body presses the outer circumferential edge of the pump seat against the step to position the pump seat; the cover body is provided with a liquid outlet hole connected to the liquid outlet, and the button can be inserted into the cover body so as to move up and down.

[0019] In order to hide the liquid outlet and prevent the liquid outlet from being exposed and contaminated, the cover is connected to a cover body through a horizontally arranged pivot, and when the cover is covered on the cover body, the cover covers the liquid outlet and the button. When the cream needs to be used, the cover is opened and the button is pressed.

[0020] In order to improve the aesthetics of the cream bottle, a decorative cover is also provided on the lid.

[0021] The channel can have a variety of structural forms, and the structure is simple. The channel includes a transverse section and a first vertical section, a second vertical section, and a third vertical section that are open at both ends. The first vertical section and the second vertical section are arranged at intervals, and the lower ends of the first vertical section and the second vertical section are both connected to the transverse section. The upper end of the first vertical section is the liquid outlet, and the upper end of the second vertical section is the opening. The valve core is movably inserted in the second vertical section, the upper end of the third vertical section is connected to the transverse section, and the lower end of the third vertical section is connected to the chamber. The liquid inlet is located in the third vertical section, and the second one-way valve is arranged in the third vertical section. In this way, there is no need to set up an additional liquid outlet, opening, and liquid inlet, and the manufacturing is simple.

[0022] In order to ensure that the chamber is in a vacuum state and that the cream always fills the space in the chamber, one method is as follows: a piston is provided in the bottle body that can move up and down relative to the bottle body, and the outer peripheral wall of the piston is sealed with the inner peripheral wall of the bottle body, and the piston and the interior of the bottle body together enclose the chamber. In this way, after the cream in the chamber is used, the piston will move upward under the action of atmospheric pressure, making the space in the chamber smaller, and the remaining cream always fills the chamber.

[0023] In order to ensure that the chamber is in a vacuum state so that the cream always fills the space in the chamber, another method is: a deformable vacuum flexible bag is provided in the bottle body, the inner space of the vacuum flexible bag is the chamber, and the top opening of the vacuum flexible bag is connected to the liquid inlet. In this way, after the cream in the chamber is used, the vacuum flexible bag will deform under the action of atmospheric pressure, making the space in the chamber smaller, and the remaining cream always fills the chamber.

[0024] Compared with the prior art, the advantages of the present invention are as follows: the present invention arranges the opening and the liquid outlet at intervals, and arranges a button that can move up and down at the opening. When the button is pressed, the air in the channel is squeezed, so that the first one-way valve is opened, and by continuously pressing the button, the cream in the vacuum chamber can enter the channel and flow out from the liquid outlet. This not only avoids the contact between the cream in the chamber and the air, but also the button and the liquid outlet are arranged at intervals, and when the button is pressed, the liquid outlet will not be blocked, which is more convenient to use. In addition, the button and the first one-way valve work independently of each other, and there will be no phenomenon that the button or the first one-way valve is interfered with by the other and gets stuck.

[0031] The present invention is further described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figures 1 to 4 As shown, the vacuum cream bottle of this preferred embodiment includes a bottle body 1, a pump base 2, a first one-way valve 3, a valve core 41, a button 42, an elastic member 43 and a second one-way valve 5.

[0034] The bottle body 1 has a chamber 11 inside which the space can always be filled with cream. The top of the chamber 11 is open, and the pump seat 2 is covered on the top of the chamber 11, so that the chamber 11 is in a vacuum state. The pump seat 2 is placed on the top wall of the bottle body 1, and the top of the bottle body 1 is threadedly connected with a cover body 6, which presses the outer periphery of the pump seat 2 against the top wall of the bottle body 1 to position the pump seat 2.

[0035] A channel 21 is provided in the pump seat 2, and a liquid outlet 22 and an opening 23 connected to the channel 21 are provided at the top of the pump seat 2. The liquid outlet 22 and the opening 23 are arranged at intervals, and a liquid inlet 24 connecting the channel 21 and the chamber 11 is provided at the bottom of the pump seat 2.

[0036] In this embodiment, the channel 21 includes a transverse section 211 and a first vertical section 212, a second vertical section 213, and a third vertical section 214 which are open at both upper and lower ends. The first vertical section 212 and the second vertical section 213 are arranged at intervals, and the lower ends of the first vertical section 212 and the second vertical section 213 are both connected to the transverse section 211. The upper end of the first vertical section 212 is the liquid outlet 22, and the cover body 6 is provided with a liquid outlet hole 61 connected to the liquid outlet 22; the upper end of the second vertical section 213 is the opening 23, the valve core 41 is movably inserted in the second vertical section 213, the upper end of the third vertical section 214 is connected to the transverse section 211, the lower end of the third vertical section 214 is connected to the chamber 11, the liquid inlet 24 is located in the third vertical section 214, and the second one-way valve 5 is arranged in the third vertical section 214.

[0037] The first one-way valve 3 is arranged at the liquid outlet 22 and can move up and down to open or close the liquid outlet 22. The first one-way valve 3 only allows the material in the channel 21 to flow out from the liquid outlet 22. The second one-way valve 5 is arranged at the liquid inlet 24. The second one-way valve 5 can move up and down relative to the liquid inlet 24 to cover or open the liquid inlet 24. The second one-way valve 5 only allows the material in the chamber 11 to flow into the channel 21. Both the first one-way valve 3 and the second one-way valve 5 can adopt any existing structure.

[0038] The valve core 41 is arranged in the opening 23. The valve core 41 can move downward relative to the opening 23 under the action of external force, and the valve core 41 maintains a sealed connection with the inner peripheral wall of the opening 23. The button 42 is located above the opening 23. The button 42 is inserted on the cover body 6 so as to be movable up and down. The button 42 is connected to the valve core 41 through the valve stem 40. The elastic member 43 is arranged outside the channel 21. The elastic member 43 acts on the button 42 so that the button 42 always maintains a tendency to move upward.

[0039] When the button 42 is pressed downward, the valve core 41 moves downward; when the downward force applied to the valve core 41 disappears, the valve core 41 returns to its original position under the action of the elastic member 43, and a flange 25 is formed on the inner wall of the opening 23 to abut against the upper end of the valve core 41. When the valve core 41 abuts against the flange 25, the valve core 41 cannot continue to move upward, preventing the valve core 41 from moving out of the opening 23 under the action of the elastic member 43.

[0040] The cover body 6 is connected to a lid 7 through a horizontally arranged pivot. When the lid 7 is covered on the cover body 6, the lid 7 covers the liquid outlet 61. When the cream needs to be used, the lid 7 is opened and the button 42 is pressed. In order to improve the aesthetics of the cream bottle, a decorative cover 8 is also provided on the lid 7.

[0041] In order to ensure that the chamber 11 is in a vacuum state and the cream always fills the space in the chamber 11, a piston 13 is provided in the bottle body 1, which can move up and down relative to the bottle body 1, and the outer peripheral wall of the piston 13 is sealed with the inner peripheral wall of the bottle body 1. The piston 13 and the interior of the bottle body 1 together form the chamber 11, and an air inlet can be provided on the bottom wall of the bottle body 1. In this way, after the cream in the chamber 11 is used, the piston 13 will move upward under the action of atmospheric pressure, so that the space in the chamber 11 becomes smaller, and the remaining cream always fills the chamber 11.

[0042] The working process of the vacuum cream bottle of this embodiment is as follows:

[0043] When the cream needs to be used, the decorative cover 8 is removed, the cover 7 is turned upward, and then the button 42 is pressed. At this time, the air in the channel 21 is compressed, the second one-way valve 5 is further pressed at the liquid inlet 24, and the first one-way valve 3 is pushed upward by the air to open the liquid outlet 22. When the button 42 is pressed continuously and the air pressure in the chamber 11 is greater than the pressure in the channel 21, the cream pushes the second one-way valve 5 into the channel 21 and flows out from the liquid outlet 22.

[0044] After the button 42 is no longer pressed, the button 42 returns to its original position under the action of the elastic member 43 , the first one-way valve 3 falls under the action of gravity and covers the liquid outlet 22 , and the second one-way valve 5 also falls under the action of gravity and covers the liquid inlet 24 .

[0045] Example 2

[0046] like Figure 5 , 6 As shown, the difference between Example 2 and Example 1 is that:

[0047] A. The bottle body 1 does not need to be provided with a piston 13. A deformable vacuum flexible bag 14 is provided in the bottle body 1. The internal space of the vacuum flexible bag 14 is the chamber 11. The top opening of the vacuum flexible bag 14 is connected to the liquid inlet 24. After the cream in the chamber 11 is used, the vacuum flexible bag 14 will be deformed under the action of atmospheric pressure, so that the space of the chamber 11 becomes smaller, and the remaining cream always fills the chamber 11.

[0048] B is not provided with a cover 7 and a decorative cover 8;

[0049] c A step 12 is formed on the inner peripheral wall of the bottle body 1 at a position adjacent to the top, and the outer peripheral edge of the pump seat 2 is placed on and pressed by the cover body 6 on the step 12.

[0050] For other structures of this embodiment, reference may be made to Embodiment 1.
