[0078] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0079] As described in the background section of this application, cosmetics are typically packaged in sealed containers (bottles), which can be opened for use.

[0080] The inventors of this application have discovered that some cosmetics, when stored at room temperature, require heating before use to reach the desired operating temperature for optimal efficacy. Furthermore, there is a risk of cosmetics being stolen without being detected.

[0081] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

Figure 15 This is a schematic diagram of the valve-open state of the cosmetic container in Embodiment 1 of this utility model.

[0084] like Figures 1 to 15 As shown, the heatable cosmetic container of this embodiment includes: an outer bottle 1, a middle bottle 2, an inner bottle 3, a gas cylinder assembly 4, a pressure cap 5, an outer cap 6, a first medium 100, and a second medium.

[0085] The gas cylinder assembly 4 is housed inside the outer cylinder 1. The gas cylinder assembly 4 includes a gas cylinder 41 and an exhaust valve 42.

[0086] The gas cylinder 41 is filled with a first medium 100, which is in a liquid state under a certain pressure. An exhaust valve 42 is provided on the mouth of the gas cylinder 41 to seal the mouth of the gas cylinder 41.

[0087] The inner bottle 2 is tubular with a through-channel. The inner bottle 3 is fitted onto the inner bottle 2 and extends into the body of the inner bottle 2. The inner bottle 3 is made of a heat-conducting material with good thermal conductivity, such as aluminum or copper, and contains cosmetic ingredients.

[0088] The outer cap 6 is fitted onto the inner bottle 2 and connected to it via a snap-fit ​​mechanism. When closed, the outer cap 6 seals the opening of the inner bottle 3, preserving the cosmetic product within the inner bottle 3. The bottom inner wall of the outer cap 6 is equipped with a locking ring 611 and an anti-theft ring 612. The locking ring 611 and the anti-theft ring 612 are connected by a connecting rib and are respectively snapped into the snap-fit ​​groove of the inner bottle 2. During use, rotating the outer cap 6 disconnects the connecting rib between the locking ring 611 and the anti-theft ring 612, separating them, allowing the outer cap 6 to be removed. Before use, if the connecting rib between the locking ring 611 and the anti-theft ring 612 is intact, it indicates that the cosmetic product has not been stolen; if the connecting rib between the locking ring 611 and the anti-theft ring 612 is broken, it indicates that the cosmetic product may have been stolen.

[0089] The outer bottle 1 has two spiral grooves 11 symmetrically arranged on the inner walls of both sides at the top. The middle bottle 2 has limiting grooves 22 symmetrically arranged on the side walls of both sides at the bottom. The cap 5 is circular and has guide posts 51 symmetrically arranged on both sides of the circumferential side wall.

[0090] The second medium (not shown in the diagram) is placed inside the middle bottle 2.

[0091] The bottom end of the inner bottle 2 extends into the outer bottle 1, and the exhaust valve 42 on the gas cylinder 41 is located on the side closer to the inner bottle 2. The exhaust valve 42 extends into the channel of the inner bottle 2, and the gas cylinder 41 is connected to the channel of the inner bottle 2 through the exhaust valve 42. The bottom end of the inner bottle 2 and the top end of the outer bottle 1 are connected by a snap fastener, and the outer bottle 1 and the inner bottle 2 can rotate relative to each other. The pressure cap 5 is fitted inside the inner bottle 2 and located at the bottom end of the inner bottle 2. The guide post 51 of the pressure cap 5 is movably locked in the limiting groove 22 of the inner bottle 2, and the guide post 22 extends out of the side wall of the inner bottle 2 and is embedded in the spiral groove 11 of the outer bottle 1. The guide post 51 can slide along the spiral groove 11 of the outer bottle 1, so that when the inner bottle 2 rotates relative to the outer bottle 1, it drives the pressure cap 5 to move up and down.

[0092] In this embodiment, under normal storage conditions, the cosmetic material is sealed in an inner bottle, the first medium is filled in a gas cylinder, and the second medium is placed in a middle bottle.

[0093] Before use, rotate the outer bottle relative to the middle bottle. The guide post of the cap slides along the spiral groove of the outer bottle. At the same time, the guide post of the cap moves up and down along the limiting groove of the middle bottle. The outer bottle drives the cap to move downward, so that the cap is close to the gas cylinder and the exhaust valve.

[0094] When the outer bottle rotates at a certain angle relative to the inner bottle, the pressure cap triggers the downward vent valve, opening it and connecting the first medium inside the gas cylinder with the inner bottle. The liquid first medium enters the inner bottle under pressure and instantly vaporizes, reacting chemically with the second medium inside the inner bottle and generating heat. This heats the inner bottle and the cosmetic material inside, bringing it to its optimal usage temperature. Then, rotating the outer cap separates the locking ring from the anti-theft ring, allowing access to the cosmetic material inside the inner bottle. Furthermore, by observing whether the connection between the locking ring and the anti-theft ring on the outer cap is damaged before use, any unauthorized use of the cosmetic can be detected promptly.

[0095] It is not difficult to see from the above that the heatable cosmetic container of this embodiment is provided with an outer bottle, a middle bottle, an inner bottle, a gas cylinder assembly, a pressure cap, an outer cap, a first medium, and a second medium. The gas cylinder assembly is fitted inside the outer bottle and includes a gas cylinder and an exhaust valve. The gas cylinder is filled with the first medium, and the exhaust valve is located on the gas cylinder. The inner bottle is fitted inside the middle bottle, and the outer cap is closed on the middle bottle. The outer cap is provided with a locking buckle and an anti-theft buckle. The locking buckle and the anti-theft buckle are connected by a connecting rib. The outer bottle is provided with a spiral groove, the middle bottle is provided with a limiting groove, the pressure cap is provided with a guide post, the second medium is placed inside the middle bottle, the outer bottle and the middle bottle are rotatably connected, the pressure cap is fitted on the middle bottle, and the guide post is locked in the limiting groove and embedded in the spiral groove. This embodiment of a heatable cosmetic container contains cosmetic material encapsulated within an inner bottle. Before use, the outer bottle is rotated at a certain angle relative to the inner bottle. The outer bottle moves the pressure cap towards the gas cylinder, triggering the opening of the exhaust valve. This allows the first medium from the gas cylinder to enter the inner bottle. The first medium reacts chemically with the second medium in the inner bottle, generating heat that heats the inner bottle and the cosmetic material within it, raising its temperature to the desired usage temperature. Then, the outer cap is rotated to open, allowing the use of the cosmetic material within the inner bottle. The cosmetic material is used after heating, ensuring optimal performance. The exhaust valve of the gas cylinder is opened by rotating the outer bottle, making operation convenient. Furthermore, by observing whether the connecting rib between the locking ring and the anti-theft ring on the outer cap is damaged, it is easy to detect if the cosmetic has been stolen.

[0096] Optional, such as Figure 2As shown, in this embodiment, the heatable cosmetic container has an inner bottle 3 fitted onto a middle bottle 2, extending into the body of the middle bottle 2. The outer diameter of the inner bottle 3 is smaller than the inner diameter of the middle bottle 2, and there is a certain distance between the inner wall of the middle bottle 2 and the outer wall of the inner bottle 3, forming a receiving space 201 between the middle bottle 2 and the inner bottle 3. The second medium is placed in the receiving space 201 of the middle bottle 2. When the exhaust valve 42 is opened, the first medium in the gas cylinder 41 enters the receiving space 201 of the middle bottle 2, reacts with the second medium to generate and release heat, heating the inner bottle 3 and the cosmetic material inside the receiving space 201. The cosmetic material is heated faster and more evenly, improving the heating efficiency of the cosmetic.

[0097] Furthermore, such as Figure 4 , Figure 6 and Figure 9 As shown, the exhaust valve 42 of the thermostatic cosmetic container in this embodiment includes: valve body 421, valve needle 422, spring 423 and rocker plate 424.

[0098] A bracket 411 is provided on the top surface of the gas cylinder 41, and a fixing rod 412 is provided on the bracket 411.

[0099] The valve body 421 is fixedly inserted into the mouth of the gas cylinder 41 to seal the mouth of the gas cylinder 41. The valve body 421 has a first fluid channel 4211 inside, which is connected to the inside of the gas cylinder 41 through the inlet 4212 at the bottom.

[0100] A convex ring 4221 is provided in the middle of the valve needle 422, a convex cap 4222 is provided at the top of the valve needle 422, a second fluid channel 4223 is provided inside the valve needle 422, an exhaust hole 4224 is provided on the bottom side wall of the valve needle 422, and a sealing gasket 4225 is provided at the bottom of the valve needle 422.

[0101] The valve needle 422 is slidably inserted into the first fluid channel 4211 of the valve body 421. The top end of the valve needle 422 extends out of the valve body 421 and is located in the receiving space 201 inside the middle bottle 2.

[0102] Spring 423 is sleeved on valve needle 422 and located within the first fluid passage 4211 of valve body 421. The bottom end of spring 423 abuts against the convex ring 4221 of valve needle 422, and the top end of spring 423 abuts against valve body 421. The sealing gasket 4225 of valve needle 422 abuts against the inlet 4212 of valve body 421, blocking the inlet 4212 of valve body 421 and sealing gas cylinder 41. The vent hole 4224 of valve needle 422 connects the second fluid passage 4223 of valve needle 422 with the first fluid passage 4211 of valve body 421.

[0103] One end of the rocker 424 is provided with a plug groove, and the middle part is provided with a mounting hole.

[0104] The rocker arm 424 is mounted on the bracket 411 of the gas cylinder 41, and is secured in the slot of the bracket 411. The fixing rod 412 on the gas cylinder 41 passes through the mounting hole of the rocker arm 424 to prevent it from slipping off the gas cylinder 41. The insertion slot of the rocker arm 424 is engaged with the valve needle 422, and the rocker arm 424 is inserted into the slot between the convex cap 4222 of the valve needle 422 and the valve body 421.

[0105] The pressure cap 5 is circular, and the top of the pressure cap 5 is provided with a pressure cap protrusion 52 extending inward.

[0106] In this embodiment, when cosmetics are needed, the outer bottle is rotated relative to the inner bottle. The outer bottle causes the pressure cap to move downwards. The pressure cap's protrusion triggers and presses the rocker arm away from the insertion slot. The rocker arm rotates, and the side of the rocker arm's insertion slot flips upwards, causing the valve needle to move upwards and rise. This causes the bottom of the valve needle to move away from the valve body's inlet. Under pressure, the liquid first medium enters the inner bottle's containing space through the valve body's first fluid channel, the valve needle's vent hole, and the second fluid channel. It reacts with the second medium in the containing space to generate heat, thus heating the cosmetic material.

[0107] Furthermore, in this embodiment, the heatable cosmetic container, gas cylinder assembly 4, also includes a temperature sensing element 43.

[0108] The temperature sensing element 43 is provided with a limiting hole 431.

[0109] The temperature sensing element 43 is mounted on the support 411 of the gas cylinder 41 and is located in the receiving space 201 inside the middle cylinder 2. The temperature sensing element 43 is mounted on the fixing rod 412 of the support 411 through the limiting hole 431 to prevent the temperature sensing element 43 from slipping off the support 411.

[0110] The upper surface of the temperature-sensing element 43 is provided with a temperature-sensing part 432, which can be a temperature-sensing label or a coated temperature-sensing layer. When the temperature inside the containing space 201 of the middle bottle 2 rises to the color-changing threshold of the temperature-sensing part 432, the color of the temperature-sensing part 432 will change from one set color to another. For example, when the temperature inside the containing space 201 rises above 40 degrees Celsius, the color of the temperature-sensing part 432 will change from white to red, and the color change process of the temperature-sensing part 432 is irreversible, that is, once the temperature-sensing part 432 changes from white to red, it cannot change back to white.

[0111] Furthermore, in this embodiment, the inner bottle 2 of the heated cosmetic container is made of transparent material, and the temperature sensing part 432 of the temperature sensing element 43 in the containing space 201 can be observed through the bottle wall of the inner bottle 2.

[0112] In this embodiment, the first medium enters the inner bottle and reacts with the second medium, generating heat and raising the temperature within the containment space, thus heating the cosmetic. When the temperature within the containment space reaches the threshold of the temperature-sensing part, the color of the temperature-sensing part changes from white to red. The inner bottle is a transparent component made of a transparent material, allowing the temperature-sensing part inside the inner bottle to be observed from the outside. When the color of the temperature-sensing part changes, it indicates that the inner bottle of cosmetic has been heated immediately, at which point the outer cap can be opened to use the cosmetic material inside the inner bottle. Furthermore, the temperature-sensing part can be used to determine whether there is a leak in the gas cylinder before use or whether the cosmetic has been stolen. If the temperature-sensing part has changed color before use, it indicates that the cosmetic may have been used or heated, enhancing the consumer's sense of security and user experience.

[0113] Of course, the color change threshold of the temperature-sensitive part corresponds to the application temperature of the cosmetic. The material of the temperature-sensitive part with a corresponding color change threshold should be selected according to the application temperature of the cosmetic.

[0114] Furthermore, in this embodiment, the heatable cosmetic container, gas cylinder assembly 4, also includes a bottle holder 45.

[0115] The bottle holder 45 is provided with a first limiting protrusion 451 and a first buckle groove 452.

[0116] The bottom end of the gas cylinder 41 is fixedly embedded in the cylinder holder 45, and the bottom end face of the gas cylinder 41 abuts against the first limiting protrusion 451 of the cylinder holder 45, thus the cylinder holder 45 protects the gas cylinder 41.

[0117] The bottom of the outer bottle 1 is provided with a second limiting protrusion 12 extending inward, and the inner wall of the outer bottle 1 is provided with a first buckle 13.

[0118] The gas cylinder assembly 4 is fitted inside the outer cylinder 1. When the gas cylinder 41 is inserted into the outer cylinder 1 from the top port, the first limiting protrusion 451 of the cylinder support 45 abuts against the second limiting protrusion 12 of the outer cylinder 1, and the first buckling groove 452 of the cylinder support 45 is engaged with the first buckling ring 13 of the outer cylinder 1 to form a buckling connection.

[0119] Furthermore, in this embodiment, the heated cosmetic container has a through hole at the bottom of the outer bottle 1, and both the gas cylinder 41 and the bottle holder 45 are made of transparent material. The first medium 100 inside the gas cylinder 41 can be observed through the through hole at the bottom of the outer bottle 1.

[0120] In this embodiment, the first medium is filled into the gas cylinder in a liquid state, and the cylinder holder and gas cylinder are made of transparent material. The status of the first medium inside the gas cylinder can be observed from the bottom of the outer bottle to confirm whether the purchased product is normal: if liquid first medium is observed inside the gas cylinder, the product is normal; if there is no liquid first medium inside the gas cylinder, it indicates that the gas cylinder has leaked or has not been filled with the first medium, and the product is abnormal, thus enhancing consumers' sense of security.

[0121] Optional, such as Figure 14 and Figure 15 As shown, in this embodiment, the heated cosmetic container has a notch 23 on the end face near the outer bottle 1 in the middle bottle 2.

[0122] The outer bottle 1 has a label 14 at its top, and the label 14 has a directional arrow. The directional arrow on the label 14 is used to indicate the rotation direction of the outer bottle 1 relative to the middle bottle 2 when the valve is opened.

[0123] The label 14 of the outer bottle 1 is embedded in the notch 23 of the middle bottle 2.

[0124] In this embodiment, the label 14 of the outer bottle 1 is set in the notch 23 of the middle bottle 2. The notch 23 can indicate the status of the exhaust valve and limit the rotation angle of the outer bottle 1: when the label 14 is located at the end of the notch 23 opposite to the rotation direction of the outer bottle 1 (left end), the exhaust valve is in the closed state; when the label 14 is located at the end of the notch 23 in the same direction as the rotation direction of the outer bottle 1 (right end), the exhaust valve is in the open state.

[0125] Optional, such as Figure 10 and Figure 11 As shown, in this embodiment, the heated cosmetic container 2 has an arc-shaped protrusion 221 at the end of the limiting groove 22.

[0126] In this embodiment, the inner bottle 2 has arc-shaped protrusions 221 at both ends of the limiting groove 22. When the exhaust valve is closed, the guide post 51 of the cap 5 is located at the upper end of the limiting groove 22. The arc-shaped protrusions 221 block and limit the guide post 51, preventing the guide post 51 from easily sliding out from the end of the limiting groove 22, thus preventing the exhaust valve of the outer bottle 1 from opening due to misoperation. Moreover, when the outer bottle 1 is rotated to open the exhaust valve, a jumping sensation of passing over the arc-shaped protrusion will be generated. Correspondingly, after the exhaust valve is opened, the guide post is located at the lower end of the limiting groove. When the exhaust valve is closed again, a jumping sensation of passing over the arc-shaped protrusion will also be generated, enhancing the user experience.

[0127] Optional, such as Figure 2 and Figure 13 As shown, in this embodiment, the heated cosmetic container has a fixed protrusion 31 extending outward from the top of the inner bottle 3.

[0128] The inner bottle 3 is fitted inside the middle bottle 2, and the fixing protrusion 31 of the inner bottle 3 is fixedly embedded in the mouth of the middle bottle 2.

[0129] The outer cover 6 is provided with a sealing ring 62. When the outer cover 6 is closed, the sealing ring 62 of the outer cover 6 is inserted into the inner bottle 3 to seal the inner bottle 3.

[0130] The inner bottle 2 has multiple venting grooves 24 on the side wall of the bottle mouth, which are evenly distributed along the circumference of the inner bottle 2. When the outer cap 6 is closed on the inner bottle 2, the venting grooves 24 of the inner bottle 2 connect the inside of the outer cap 6 with the outside atmosphere, ensuring that the outer cap 6 closes smoothly.

[0131] Furthermore, in this embodiment, the first medium of the heatable cosmetic container is oxygen, and the second medium is iron powder.

[0132] Oxygen is filled into gas cylinder 41 in a liquid state under certain pressure, and iron powder is placed in the containment space 201 of the middle bottle 2.

[0133] When the exhaust valve is opened, oxygen enters the inner bottle's containment space, reacts chemically with the iron powder, generates and releases heat, thus heating the cosmetic material and the temperature-sensing component.

[0134] Example 2

[0135] Figure 16 This is a cross-sectional schematic diagram of the cosmetic container in Embodiment 2 of this utility model. Figure 17 This is a schematic diagram of the inner bottle in Embodiment 2 of this utility model. Embodiment 2 is an improvement on Embodiment 1.

[0136] like Figure 16 and Figure 17 As shown, in this embodiment, the bottom end of the inner bottle 3 of the heated cosmetic container is hemispherical. The inner bottle 3 has an arc-cut sidewall at the bottom end of the hemispherical shape. The position of the arc-cut sidewall of the inner bottle corresponds to the position of the temperature sensing part on the temperature sensing element.

[0137] The inner bottle 3 is made of a thermally conductive material such as aluminum and has a smooth outer wall. The reflection from the rounded side wall of the inner bottle makes it easier to observe the temperature sensing part on the temperature sensing element.

[0139] Furthermore, "above," "on top of," and "above" the first feature in relation to the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" the first feature in relation to the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
