Description

Technical Field

[0001] The present invention relates to the technical field of cosmetic packaging, in particular to a sterilization vacuum cover and a corresponding cosmetic bottle. Background Art

[0002] like Figure 1 As shown, traditional cosmetic bottles generally consist of a bottle cap and a bottle body, which are connected by a threaded connection. When consumers need to use the material in the bottle, they generally unscrew the bottle cap directly and then use their fingers to pick up the material in the container. This action will bring in certain fungi, thereby contaminating the remaining material in the container. Therefore, when using such a container to hold the material, a certain amount of preservatives needs to be added to the material formula to inhibit fungal growth.

[0003] Some cosmetic formulas with special storage requirements have higher requirements for the storage environment, and the above-mentioned traditional cosmetic bottles cannot meet their storage requirements. For example, some high-concentration vitamin C needs to be stored in a light-proof and oxygen-isolated environment, otherwise it will easily oxidize and deteriorate. The environment in which the material is stored has a significant impact on its shelf life.

[0004] In the prior art, for some cosmetic formulas that are sensitive to air, vacuum bottles are generally used to store such materials. The structure of the vacuum bottle can be found in Figure 2 As shown, the material is placed in a bottle or a can, the upper part of which is a pump core, and the lower part of the material is a piston. As the upper pump core works, the piston is affected by the external atmospheric pressure and pushes the remaining material upward, filling the entire cavity with the material.

[0005] Although the cosmetic bottles and vacuum bottles in the above-mentioned prior art can play the role of placing the material, they have the following problems:

[0006] When using conventional cosmetic bottles to hold cosmetics, preservatives are often added to prevent bacterial contamination, as the user's fingers will come into contact with the cosmetics when removing them. However, the use of preservatives in the cosmetics can be harmful to consumers' skin. Long-term use of products containing preservatives can affect skin texture. Preservatives can cause immature development of epidermal cells, leading to loss of elasticity and the development of fine lines. Furthermore, some consumers may experience skin allergies to preservatives.

[0007] Existing vacuum bottles and jars, however, prevent consumers from fully consuming the formula in the bottle or jar. Currently, the typical vacuum bottle or jar usage rate is around 90%. Due to their design, the final contents of the bottle cannot be removed, resulting in material waste. Furthermore, for air-sensitive materials, the filling process of vacuum bottles and jars requires that air remain in the headspace at the outlet of the vacuum bottle or jar after the container is sealed, which can oxidize the material. Only after the consumer activates the product and uses the pump to expel the air in the headspace is the container completely filled with the formula. Summary of the Invention

[0103] In order to make the technical means, creative features, objectives and effects of the invention easier to understand, the invention is further described below with reference to specific diagrams. However, the invention is not limited to the following implementation cases.

[0104] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them. They are not used to limit the conditions under which the present invention can be implemented. Therefore, they have no substantive technical significance. Any modification of the structure, change in the proportion relationship or adjustment of the size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0105] Example 1:

[0106] See Figures 3 to 10 As shown (where Figures 4 to 6 (The evenly distributed oblique lines in the figure are hatching lines). In this embodiment, the cosmetic bottle is composed of a sterilization vacuum cover 1 and a bottle body 2. The sterilization vacuum cover 1 is detachably connected to the bottle body 2. In a specific implementation, the sterilization vacuum cover 1 and the bottle body 2 can be connected by a threaded connection, or other connection methods can be used.

[0107] The bottle body 2 can be made of glass or plastic jars in the prior art. When the bottle body 2 is made of light-proof material, it can also achieve the effect of shading.

[0108] An inner cover and a foam gasket are provided between the sterilization vacuum cover 1 and the bottle body 2. The inner cover is adjacent to the bottle body 2, and the foam gasket is provided on a side of the lower cover 112 of the sterilization vacuum cover 1 adjacent to the bottle body 2. The inner cover can be snapped onto the bottle mouth of the bottle body 2, and the design of the foam gasket can make the connection between the sterilization vacuum cover 1 and the bottle body 2 tighter, effectively improving the sealing performance.

[0109] In this embodiment, the sterilization vacuum cover 1 comprises:

[0110] The bottle cap body 11 has an internal accommodating cavity, and a first through hole is provided on the bottom surface of the accommodating cavity;

[0111] An air extraction mechanism is provided in the accommodating cavity, and an air extraction port of the air extraction mechanism is connected to the first through hole;

[0112] The sterilization mechanism is provided on the bottom surface of the accommodating cavity adjacent to the bottle body 2;

[0113] A control component is arranged in the accommodating cavity, and the control component is connected to the air extraction mechanism and the sterilization mechanism respectively.

[0114] like Figures 3 to 7 As shown, in this embodiment, the bottle cap body 11 includes an upper cover body 111 and a lower cover body 112. The upper cover body 111 and the lower cover body 112 are snap-fitted together, and the accommodating cavity is formed by the space formed between the upper cover body 111 and the lower cover body 112. When in use, the lower cover body 112 is connected to the bottle body 2 through the threads on the lower cover body 112.

[0115] In actual application, the present invention uses the existing can container as the bottle body 2. The user can open the vacuum lid to obtain the material, so that the exhaustion rate of the material reaches 100%. The air in the head of the can is discharged after each use by the consumer, relying on the function of the air extraction mechanism hidden in the middle of the lid. This effectively reduces the air pressure in the head space of the can and reduces the impact of the air on the material. It can also well preserve some skin care formulas that are easily oxidized and deteriorated. It reduces the fungi floating in the air and aerobic fungi on the material. In addition, considering that the consumer's fingers may bring in fungi when touching the material, the present invention relies on the air pump 121 to discharge the fungi floating in the air at the head. At the same time, under the irradiation of the ultraviolet lamp 141, the fungi on the surface of the remaining material are disinfected.

[0116] In this embodiment, the sterilization vacuum cover 1 further includes a vacuum breaking component 13, the vent of the vacuum breaking component 13 is connected to the second through hole located on the bottom surface of the accommodating cavity, and the control end of the vacuum breaking component 13 extends from the third through hole on the top surface of the accommodating cavity and is arranged on the outside of the bottle cap body 11. Figure 6 As shown, in this embodiment, the vacuum breaking assembly 13 includes a duckbill valve 131, a button 134, a rod 132 and a spring 133;

[0117] The button 134 is connected to the valve end of the duckbill valve 131 through the insertion rod 132, wherein the first exhaust hole on the button 134 is connected to the valve end of the duckbill valve 131 through the second exhaust hole in the insertion rod 132;

[0118] The spring 133 is sleeved on the outside of the insertion rod 132, and the spring 133 is supported between the top surface of the accommodating cavity and the top surface of the second through hole;

[0119] The vent hole of the duckbill valve 131 constitutes the vent of the vacuum breaking component 13, and the button 134 constitutes the control end of the vacuum breaking component 13. The duckbill valve 131 is a one-way valve.

[0120] By setting up the vacuum breaking assembly 13, when the consumer wants to open the can, there is a button 134 on the top of the can, and below the button 134 is an insertion rod 132 and a spring 133. When the button 134 is in the initial position, the insertion rod 132 does not contact the duckbill valve below.

[0121] The connection structure between the button 134 and the inserting rod 132 can be found in Figure 9 As shown, the button 134 and the rod 132 can be an integrated structure. The structure of the duckbill valve 131 can be referred to Figure 10 As shown, it can be seen from the figure that the bottom end of the insertion rod 132 is flat, and a flat opening is provided in the duckbill valve.

[0122] When the button 134 is pressed, the rod 132 will enter the duckbill valve, causing the flat opening to open. At the same time, the vertical exhaust groove on the rod 132 will also enter the duckbill valve to achieve the purpose of exhaust, thereby increasing the air pressure in the can and making it easier for consumers to open the lid.

[0123] When the button 134 is released, the spring 133 lifts the button 134 and the rod 132 to their initial positions. The connection between the duckbill valve and the rod 132 returns to its initial position, and the exhaust groove on the rod 132 leaves the duckbill valve, closing the flat opening on the duckbill valve and returning to a closed state.

[0124] like Figure 3As shown, in this embodiment, the control component includes:

[0125] The pressure sensor 171, the trigger end of the pressure sensor 171 is arranged at a position in the bottle cap body 11 that can contact the bottle body 2 when connected to the bottle body 2. For specific positions, please refer to Figure 5 As shown;

[0126] The driving mechanism is arranged in the accommodating cavity, and the driving mechanism is respectively connected to the pressure sensor 171, the exhaust mechanism and the sterilization mechanism. The driving mechanism can be composed of control components such as a single chip microcomputer, or can be composed of a circuit board 181 with a control device.

[0127] Through the design of this structure, the user can trigger the pressure sensor 171 when covering the bottle body 2 with the sterilization vacuum cover 1, thereby driving the exhaust mechanism and the sterilization mechanism to work through the driving mechanism.

[0128] In this embodiment, the air extraction mechanism is composed of a vacuum pump, which can be composed of an air pump 121 with an electric motor, or a physical pump core.

[0129] However, if a physical pump core is used to form a vacuum pump, consumers need to manually press the upper part continuously to gradually discharge the gas when using it. However, using an air pump 121 with an electric motor to form a vacuum pump has the characteristics of being easy to use and saving time.

[0130] When the vacuum pump is composed of an air pump 121 with an electric motor, and the sterilization vacuum cover 1 is connected to the bottle body 2 through threads, when the consumer closes the cover, the pressure sensor 171 is pressurized by the action of the threads as the bottle body 2 and the sterilization vacuum cover 1 below approach each other, and the device is started, and under the control of the drive mechanism, the air pump 121 with the electric motor is started.

[0131] The air pump 121 starts working to discharge the air in the enclosed head space of the bottle body 2. By calculating the discharge efficiency of the air pump 121 (for example, 0.5 ml / s) and the head space (for example, 50 ml / empty can, 3 ml / full can), we can use the driving mechanism to control the working time of the air pump to achieve a suitable internal low air pressure.

[0132] During implementation, the calculated preset working time of the air pump can be stored in the control component, and the air pump will pump air for a fixed time each time;

[0133] Alternatively, the working time of the air pump can be linked to the number of times the bottle is opened. Each time the bottle is opened, the air extraction time is extended by a preset time, so that the air extraction time of the air extraction mechanism changes with the usage of the material in the bottle.

[0134] Alternatively, the working time of the air pump can be associated with the usage time of the sterilization vacuum cover 1. Every time a preset time interval passes, the sterilization vacuum cover 1 extends the vacuum time by a certain preset time, so that the vacuum time of the vacuum mechanism can also change with the usage of the material in the bottle.

[0135] For some smaller tanks, it is more suitable to use a fixed-duration vacuuming method for vacuuming, while for some larger tanks, it is more suitable to control the vacuuming time by a vacuuming time related to the number of uses or time and other factors.

[0136] In this embodiment, the sterilization mechanism is composed of an ultraviolet lamp 141, which faces the bottle body 2. The irradiation wavelength of the ultraviolet lamp 141 is between 200 nanometers and 280 nanometers.

[0137] The inner cover and the foam gasket are both provided with through holes for the ultraviolet lamp 141, the air extraction port in the air extraction mechanism, the air vent in the vacuum breaking assembly 13 and other components to pass through. During use, when the consumer closes the lid, the screw thread acts as the bottle body 2 and the sterilization vacuum cover 1 below approach, pressurizing the pressure sensor 171, activating the device. Under the control of the drive mechanism, the ultraviolet lamp 141 is activated, and the light-emitting portion of the ultraviolet lamp 141 passes through the inner cover and the foam gasket, allowing the ultraviolet light to irradiate the surface of the remaining material. The irradiation time can be controlled to about 2 seconds, and the ultraviolet light is used to irradiate the material to sterilize it.

[0138] In this embodiment, the sterilization vacuum cover 1 further includes:

[0139] A power supply component is respectively connected to the air extraction mechanism, the sterilization mechanism and the control component, and the power supply component is arranged in the accommodating cavity.

[0140] In this embodiment, the power supply assembly includes:

[0141] A rechargeable battery 151 is disposed in the accommodating cavity, and the rechargeable battery 151 is respectively connected to the air extraction mechanism, the sterilization mechanism, and the control component to provide power to the air extraction mechanism, the sterilization mechanism, and the control component;

[0142] The charging port 152 is connected to the rechargeable battery 151 , and the charging port 152 is provided at the fourth through hole of the bottle cap body 11 , wherein the fourth through hole is communicated with the outer side of the bottle cap body 11 .

[0143] A user can charge the rechargeable battery 151 through the charging port 152 .

[0144] In this embodiment, the sterilization vacuum cover 1 further includes:

[0145] The prompt component is arranged on the outside of the bottle cap body 11, and the prompt component is connected to the control component.

[0146] In this embodiment, the prompt component can be composed of an LED indicator light 161.

[0147] The sterilization vacuum cover 1 is provided with a charging port 152 and a working indicator light composed of an LED indicator light 161 connected to the control component. Figure 4 and Figure 8 As shown, in this embodiment, the LED indicator light 161, the charging port 152 and the button 134 are all arranged at easily accessible positions on the outside of the sterilization vacuum cover 1 for user operation or observation.

[0148] During operation, the indicator light may illuminate blue when the air pump 121 or the UV lamp 141 is operating. When the operation is complete, the indicator light turns off. When the battery is low, the indicator light flashes red. When the device is connected to an external charger, the indicator light turns solid red. When charging is complete, the indicator light turns green. In other implementations, other indication methods may be used to indicate the operating status of the sterilization vacuum lid 1, and are not limited to the above-described indication methods.

[0149] In this embodiment, the connections between the through-holes in the lower cover 112 and the corresponding components are sealed, for example, by providing sealing assemblies at corresponding locations, by interferingly connecting the components passing through the through-holes in the lower cover 112 with the corresponding through-holes in the foam gasket, or by other methods that achieve a hermetic seal. This prevents external air from entering the bottle body 2 through the gaps between the through-holes in the lower cover 112 and the air extraction port of the air extraction mechanism, the duckbill valve 131, the pressure sensor 171, or the sterilization mechanism. However, the upper cover 111 and the lower cover 112 are not hermetically connected, nor are the connections between the through-holes in the upper cover 111 and the components. Therefore, air extracted by the air extraction mechanism can be discharged from the accommodating cavity of the bottle cap body through the gap between the upper cover 111 and the lower cover 112, the third through-hole on the top surface of the accommodating cavity, the LED indicator 161, or other ventilated locations in the bottle cap body. This structural design is more simplified.

[0150] In other embodiments, additional through holes may be provided to connect to the air outlet of the air extraction mechanism for exhaust.

[0151] The sterilization vacuum cover 1 in the above embodiment can be applied to the bottle body 2 in the prior art, so that it can sterilize and vacuum preserve the material without modifying the bottle body 2 in the prior art, and has good adaptability.

[0152] By using the sterilization vacuum cover 1 and the corresponding cosmetic bottle in the above embodiment, consumers can still pick up the material with their fingers, so that the material consumption rate reaches 100%. The air in the head space after the cover is closed is discharged through the mechanism, which reduces the air pressure in the head space of the can. When the cover is closed at the filling plant, the mechanism can operate to discharge the air in the head of the sealed can, reducing the effect of air on the material during storage and transportation. At the same time, in order to avoid the cosmetic bottle being difficult to open, a vacuum breaking component 13 is also provided in the sterilization vacuum cover 1, so that when the cosmetic bottle is opened, when the air pressure in the head space of the bottle body 2 is low, the button 134 in the vacuum breaking component 13 is pressed down to insert the rod 132 into the duckbill valve 131, thereby achieving the function of air intake, so that the air pressure inside and outside the can tends to be stable, making it convenient for consumers to open the cover.

[0153] As for the problem of consumers potentially bringing in fungi every time they touch the material with their fingers, the sterilization vacuum lid 1 in this embodiment uses ultraviolet light 141 to disinfect the surface of the material after the user puts on the lid each time using the material in the bottle, so as to reduce the growth of fungi.

[0154] In one embodiment, a sterilization vacuum cover is characterized by comprising:

[0155] The bottle cap body has an internal accommodating cavity, and a bottom surface of the accommodating cavity is provided with a first through hole;

[0156] An air extraction mechanism is provided in the accommodating cavity, and an air extraction port of the air extraction mechanism is connected to the first through hole;

[0157] A sterilizing mechanism is provided on the bottom surface of the accommodating cavity adjacent to the bottle body;

[0158] A control component is arranged in the accommodating cavity, and the control component is connected to the air extraction mechanism and the sterilization mechanism respectively.

[0159] In one embodiment, the sterilization vacuum cover is further provided with a bottle opening and vacuum breaking drive assembly for performing a vacuum breaking operation when the vacuum cover is opened.

[0160] Among them, the bottle opening and vacuum breaking drive assembly includes a valve opening assembly, which is connected to a duckbill valve provided on the bottom surface of the bottle cap body. The first end of the valve opening assembly is provided in a position in the bottle cap body that can contact the bottle body when connected to the bottle body, and the second end of the valve opening assembly is connected to the duckbill valve. The valve opening assembly drives the duckbill valve to open when the vacuum cap is opened, and drives the duckbill valve to close when the vacuum cap is tightened.

[0161] In one embodiment, the control component may include:

[0162] The opening and closing detection component is connected to the exhaust mechanism and is used to control the exhaust mechanism to perform an exhaust operation when a closing signal of the sterilization vacuum cover is detected, and to control the exhaust mechanism to perform an exhaust operation when an opening signal of the sterilization vacuum cover is detected.

[0163] In one embodiment, the opening and closing detection component can be composed of a mechanical switch or a touch switch.

[0164] Example 2:

[0165] Most of the structure of the cosmetic bottle in this embodiment is the same as that of the cosmetic bottle in Example 1, so it will not be repeated here. Only the differences between the two are described below:

[0166] In one embodiment, the cosmetic bottle may further be provided with a pressure relief assembly, the pressure relief assembly comprising a sealing rotary cover provided on the accommodating cavity of the bottle cap body and a first protrusion provided on the bottle body;

[0167] The sealing rotary cover is provided with a first air vent, the bottom surface of the bottle cap body is provided with a second air vent, and the bottom surface of the sealing rotary cover is provided with a second protrusion;

[0168] The relative rotation of the sterilization vacuum cover and the bottle body causes the first protrusion to push the second protrusion to drive the sealing rotary cover to rotate, so that when the bottle cover is closed, the first air vent and the second air vent are staggered to achieve airtightness; when the bottle cover is opened, the first air vent and the second air vent are coaxially arranged to achieve pressure relief.

[0169] In one embodiment, a cosmetic bottle includes a bottle body, a bottle cap, and an identification component; wherein:

[0170] The identification component includes an identification label provided on the bottle body and an identification component provided on the bottle cap;

[0171] Wherein, each identity tag matches the corresponding material in the bottle body, and the identity recognition component is used to determine the type of material in the bottle body closed and connected with the bottle cap by detecting the identity tag;

[0172] The bottle cap includes a bottle cap body, a lighting component and a control component;

[0173] The control component is arranged in the accommodating cavity inside the bottle cap body, and the lighting component is arranged on the side of the bottle cap body adjacent to the bottle body, and the lighting component includes different types of light sources (such as lighting mechanisms that emit different colors, ultraviolet lamps, etc.), and the control component is respectively connected to the lighting component and the identification component. The control component is used to control the operation of the corresponding light source in the lighting component according to the type of material identified by the identification component, so as to achieve targeted and better protection of different types of material.

[0174] Example 3:

[0175] See Figures 11 to 14 As shown (where Figure 11 、 Figure 13 and Figure 14 (The evenly distributed oblique lines in the figure are hatching lines). In this embodiment, the cosmetic bottle is composed of a sterilization vacuum cover 1 and a bottle body 2. The sterilization vacuum cover 1 is detachably connected to the bottle body 2. In a specific implementation, the sterilization vacuum cover 1 and the bottle body 2 can be connected by a threaded connection, or other connection methods can be used.

[0176] In this embodiment, the bottle cap body includes an upper cover body 111, a lower cover body 112 and a sealing floating assembly;

[0177] The lower cover body includes a bottle body connecting portion, an inner extension portion 1122 and an upper cover connecting portion 1123;

[0178] The lower cover is connected to the upper cover via the upper cover connection portion 1123, and the accommodating cavity is formed by the spacing space formed between the upper cover and the lower cover;

[0179] The bottle body connecting portion is disposed around the outer side of the inner extension portion 1122, and a preset distance is separated from the inner extension portion 1122; the bottom surface of the inner extension portion 1122 constitutes the bottom surface of the accommodating cavity;

[0180] The sealing floating assembly includes a floating member, which is arranged around one side of the inner extension portion 1122 adjacent to the bottle body connection portion. The inner extension portion 1122 is also provided with an upper limit member 11221 and a lower limit member 11222. The floating member can move up and down between the upper limit member 11221 and the lower limit member 11222.

[0181] When the floating member does not move to the upper limit position 11221, a gas flow channel is formed between the floating member and the inner extension portion 1122; when the floating member moves to the upper limit position 11221, the gas flow channel between the floating member and the inner extension portion 1122 is closed.

[0182] In this embodiment, the floating member includes a floating member 41 and a Y-shaped seal 42. The Y-shaped seal 42 is annularly disposed within the floating member 41 on one side facing the bottle body connection portion. Driven by the floating member 41, the Y-shaped seal 42 moves up and down between the upper limit member 11221 and the lower limit member 11222. A gas flow channel may be formed between the floating member 41 and the inner extension 1122. The Y-shaped seal 42 is constructed of an elastic material (the Y-shaped seal 42 may be constructed of the same material as a conventional sealing ring). The figure depicts the Y-shaped seal 42 as undeformed by the bottle body only to better illustrate its shape. In actual use, the Y-shaped seal 42 will be deformed by the bottle body upon contact. This Y-shaped seal 42 can achieve a better seal.

[0183] In this embodiment, the sealed floating assembly also includes a sealing gasket 43, which is provided on the lower cover body and is located above the floating member. When the floating member moves to the upper limit member 11221 in the inner extension portion 1122, the top surface of the floating member contacts the sealing gasket 43.

[0184] In this embodiment, the sealing floating assembly also includes a sealing convex ring 44, which is provided on the inner extension portion 1122 and / or the floating member. When the floating member moves to the upper limit member 11221, the sealing convex ring 44 enables the inner extension portion 1122 to be interference fit with the floating member.

[0185] Figure 11 This is a cross-sectional view taken from a first angle when the cosmetic bottle of the present invention is fully closed in this embodiment. Figure 13 Schematic diagram of the cosmetic bottle of the present invention in this embodiment when slightly opened. Figure 14 Schematic diagram of the cosmetic bottle of the present invention when it is opened in this embodiment. Figure 13 As shown, when the sterilization vacuum cap 1 is slightly opened from the bottle body, the floating member 41 and the Y-shaped seal 42 will first remain relatively stationary with the bottle body under the action of friction, while the bottle cap body and the sealing gasket will move slightly upward, thereby forming a certain gap between the bottle cap body and the floating member 41. Figure 13 Enter the cosmetic bottle in the direction of the arrow, making the subsequent bottle opening action smoother.

[0186] According to the applicant's multiple tests, it was found that when a bottle in a vacuum state is opened, it will first go through a period of time that is relatively easy to open. Then, because the container is in a vacuum state, it will become difficult to open. The design of the floating part 41 and the Y-shaped seal 42 in this embodiment can form a certain gap between the bottle cap body and the floating part 41 after the cosmetic bottle is opened for a period of time, allowing external air to enter the bottle body along the air, thereby breaking the vacuum, allowing the user to open the bottle conveniently. Then, when the sterilization vacuum cap 1 is fully opened, the floating part 41 and the Y-shaped seal 42 can be separated from the bottle body under the drive of the lower limit member.

[0187] like Figure 11 As shown, a one-way valve 5 is provided between the air extraction port and the first through hole. An isolation mesh 6 is also provided at the first through hole. The isolation mesh 6 can be made of wire mesh with a mesh size of 200 to 300. This structural design allows only the gas within the bottle to be extracted, while the liquid, paste, or powdered material within the bottle is isolated by the isolation mesh 6, preventing it from entering the storage chamber. In this embodiment, a duckbill valve is used to form the one-way valve 5.

[0188] In this embodiment, a through hole is provided on the bottom surface of the accommodating cavity for the light source of the ultraviolet lamp to pass through, and a transparent baffle is provided at the through hole. The transparent baffle can be made of quartz glass 7.

[0189] Table 1 below is a table showing pressure changes of cosmetic bottles using the sterilization vacuum cover in Example 1, and Table 2 below is a table showing pressure changes of cosmetic bottles using the sterilization vacuum cover in Example 3:

[0190]

[0191] Table 1

[0192]

[0193] Table 2

[0194] Comparing the experimental results in Table 1 and Table 2 above, it can be seen that the sterilization vacuum cover including the floating member in this embodiment has a better sealing effect than the sterilization vacuum cover structure in Example 1.

[0195] Figure 15 This is a comparison chart of vitamin C decay experiments. From top to bottom, the figure shows the vitamin C decay ratio when the vitamin C-containing material is stored in the cosmetic bottle of the present invention, the vitamin C decay ratio when the vitamin C-containing material is stored in the canned cosmetic bottle with thread sealing in the prior art, and the vitamin C decay ratio when the vitamin C-containing material is stored in the cosmetic bottle with non-complete sealing in the prior art. The figure plots the initial time node of the test (i.e. Figure 15), the vitamin C decay ratio at 2 weeks from the initial time point and 6 weeks from the initial time point. Comparing the results in the figures clearly shows that the cosmetic bottle using the vacuum evacuation method of the present invention can better store materials containing vitamin C.

[0196] Comparison of the experimental data above demonstrates that the bottle cap of the present invention, by providing an exhaust mechanism and a sterilization mechanism within the bottle cap body, allows for the removal of excess air from the bottle body after the cap is secured to the bottle body. This reduces the effects of air on the material during storage and transportation, effectively storing the material. Simultaneously, the sterilization mechanism sterilizes the material within the bottle body, reducing contamination from external bacterial flora. This ensures that the user can consume the entire bottle while minimizing the effects of air or external bacterial flora on the material.

[0197] The preferred embodiments of the present invention have been described in detail above. It should be understood that numerous modifications and variations based on the concepts of the present invention are possible without inventive effort by those skilled in the art. Therefore, any technical solution that can be derived by one skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
