Detailed Implementation

[0031] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and 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.

[0032] like Figures 1-12 As shown, this embodiment discloses a cooling packaging based on pressure-triggered cold air release, including a bottle cap 1, a bottle body 2, and an air inlet valve 3. The bottle body 2 includes an inner bottle 21, an outer bottle 22, and a bottom cap 23. The bottle cap 1 is installed at the upper opening of the inner bottle 21. The inner bottle 21 includes a cavity for storing skincare essence. The inner bottle 21 is fixedly installed on the outer bottle 22, and the inner bottle 21 is at least partially located inside the outer bottle 22. A cavity 221 for storing the medium is formed between the inner bottle 21 and the outer bottle 22. The pressure inside the cavity 221 is greater than atmospheric pressure, and the pressure inside the cavity 221 is 5Kg to 15Kg. The medium inside the cavity 221 is liquid or solid under high pressure, for example, the medium is a refrigerant. The inner bottle is in a liquid state. The bottom cover 23 is fixedly installed on the outer bottle 22, and an air passage 231 is formed between the bottom cover 23 and the outer bottle 22. The inner bottle 21 includes a mounting base 211, and an air inlet valve 3 is installed on the mounting base 211. The air inlet valve 3 connects the cavity 221 and the air passage 231. The medium in the cavity 221 forms a cooling gas that flows to the air passage 231. When the medium is released, it forms a cooling gas. During the process of the condenser liquid turning into gas and vaporizing, it absorbs heat from the surrounding environment and the bottle 2, so that the condenser gas has a cooling effect. The gas can flow through the air passage 231 through the bottle 2 to cool the bottle 2, so that the skin care essence stored in the cavity of the inner bottle 21 can be cooled.

[0033] like Figures 2 to 10As shown, the bottle cap 1 includes an outer cap 11, an inner cap 12, and a threaded cap 13. The threaded cap 13 is at least partially located within the inner cap 12 and is threadedly installed at the upper opening of the inner bottle 21. The bottle cap 1 includes a pressing groove 123 located within the inner cap 12. The pressing groove 123 is located on the end face of the inner cap 12 facing the air intake valve 3 and extends circumferentially. The pressing groove 123 abuts against the air intake valve 3. The pressing groove 123 includes a first part 1231 and a second part 1232. The first part 1231 is a plane, and the second part 1232 is an inclined plane. When the bottle cap 1 is rotated, the inclined surface of the valve 3 presses against the upper end of the inlet valve 3, thereby pressing down the inlet valve 3 to achieve the purpose of opening. When the first part 1231 presses against the inlet valve 3, the inlet valve 3 blocks the cavity 221 and the air passage 231. When the bottle cap 1 is rotated, the inlet valve 3 presses against the pressure groove 123 and enters the second part 1232 from the first part 1231. When the second part 1232 presses against the inlet valve 3, the inlet valve 3 opens and connects the cavity 221 and the air passage 231. The medium is released through the inlet valve 3 to form a cooling gas that enters the air passage 231.

[0034] like Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the inner cover 12 has a through groove 121 on its side wall, which connects to the inner wall of the inner cover 12. The inner cover 12 has a locking block 122 located in the through groove 121, with one end of the locking block 122 connected to the lower edge of the through groove 121. The locking block 122 is elastically deformable. The outer wall of the toothed cover 13 has a guide groove 131, and the locking block 122 is at least partially located in the guide groove 131. The toothed cover 13 has a limiting strip 133, and the locking block 122 can... The guide groove 131 is divided into a first region 1311 and a second region 1312 by the elastic deformation of the guide strip 133. The tooth cover 13 is provided with an inlet 132, which connects the upper end face of the tooth cover 13 and the guide groove 131. The inlet 132 is located above the first region 1311. When the inner cover 12 and the tooth cover 13 are installed, the locking block 122 is engaged into the first region 1311 through the inlet 132. The guide strip 133 can... The locking block 122 is positioned within the first region 1311 to prevent the inner cover 12 from rotating unexpectedly and to prevent the air intake valve 3 from opening unexpectedly. When the first part 1231 abuts against the air intake valve 3, the locking block 122 is located in the first region 1311. When the second part 1232 abuts against the air intake valve 3, the locking block 122 is located in the second region 1312. The limiting strip 133 can limit the locking block 122 within the second region 1312, so that the air intake valve 3 can maintain communication between the cavity 221 and the air passage 231. The process of the bottle cap 1 rotating to release the refrigerant gas occurs before the bottle cap 1 is opened by screwing on the thread. When the inner cover 12 rotates and the locking block 122 abuts against the end of the second region 1312 away from the limiting strip 133, the thread between the toothed cap 13 and the inner bottle 21 is stressed, allowing the bottle cap 1 to open. The direction in which the inner cover 12 rotates to open the air intake valve 3 is the same as the rotation direction of the threaded opening of the bottle cap 1.

[0035] like Figure 8 , Figure 9 As shown, more preferably, the outer wall of the inner bottle 21 is provided with a limiting block 212, and the inner wall of the toothed cap 13 is provided with a stop block 134 and a protrusion 135. The protrusion 135 has an arc-shaped side wall, which facilitates the limiting block 212 to pass over. A groove 136 corresponding to the limiting block 212 is formed between the stop block 134 and the protrusion 135. When the first part 1231 abuts against the air inlet valve 3, the limiting block 212 is located in the groove 136, which forms a limit on the rotation of the cap 1, further preventing the cap 1 from accidentally rotating and causing the refrigerant gas to leak.

[0036] like Figure 1 , Figure 2 , Figure 5 , Figure 6As shown, the outer cover 11 and the inner cover 12 are fixedly installed. The inner cover 12 is at least partially located inside the outer cover 11. The outer cover 11 has the same shape as the bottle body 2. The inner cover 12 also includes an ear plate 124, which can increase the area of ​​the lower end face of the inner cover 12. The through groove 121 connects to the upper end face of the inner cover 12. The inner wall of the outer cover 11 is provided with two limiting plates 111. The two limiting plates 111 abut against the two sides of the through groove 121 respectively. The outer cover 11 and the inner cover 12 are provided with an annular fastening structure, and the fixed connection is achieved by limiting the rotation direction between the limiting plates 111 and the through groove 121.

[0037] like Figure 2 , Figure 3 , Figure 9 , Figure 10 , Figure 11 As shown, the mounting base 211 is provided with a mounting hole 2111 and a connecting port 2112. The connecting port 2112 connects the mounting hole 2111 and the side wall of the mounting base 2111, and connects the air passage 231. The mounting hole 2111 connects the upper end face and the lower end face of the mounting base 2111. The upper end of the mounting hole 2111 corresponds to the first through hole 241, and the lower end of the mounting hole 2111 connects to the cavity 221. The air inlet valve 3 is installed in the mounting hole 2111, and part of the air inlet valve 3 passes through the first through hole 241. The bottle body 2 includes a shoulder sleeve 24, which is fixedly installed in the mounting base 211. The shoulder sleeve 24 is provided with a first through hole 241 and a second through hole 242. At least part of the inner bottle 21 passes through the second through hole 242, and the button 31 passes through the first through hole 241. The shoulder sleeve 24 can close the upper opening of the connecting port 2112. The shoulder sleeve 24 serves to limit the position of the air inlet valve 3 and to improve the appearance of the bottle body 2.

[0038] The intake valve 3 includes a button 31, a valve stem 32, a spring 33, a sealing ring 34, and a plug 35. The valve stem 32 is slidably mounted in the mounting hole 2111. The plug 35 and the button 31 are located at opposite ends of the valve stem 32. The side wall of the button 31 has a shoulder 311. The fourth channel 321 is located on the side of the shoulder 311 near the valve stem 32. The shoulder sleeve 24 limits the upward movement of the button 31. The spring 33 and the sealing ring 34 are mounted on the valve stem 32. The outer wall of the valve stem 32 has a first step. 322, the inner wall of the mounting hole 2111 is provided with a second step 21111, one end of the spring 33 abuts against the first step 322, and the other end of the spring 33 abuts against the sealing ring 34. The spring 33 provides an upward support force for the button 31 and the valve stem 32. The sealing ring 34 abuts against the second step 21111. The sealing ring 34 can seal the side wall of the valve stem 32 and the second step 21111 when the valve stem 32 moves downward, preventing gas from entering the mounting hole 2111 and directly contacting the spring 33.

[0039] Button 31 abuts against pressure groove 123. Button 31 is provided with a third channel 312. Valve stem 32 is provided with a fourth channel 321. The third channel 312 connects the fourth channel 321 and the connecting port 2112. The fourth channel 321 connects the third channel 312 and the outer wall of valve stem 32. One end of the fourth channel 321 that connects to the outer wall of valve stem 32 is located on the side of plug 35 near button 31. When the first part 1231 abuts against button 31, shoulder 311 abuts against shoulder sleeve 24, plug 35 blocks the lower end of mounting hole 2111, and air intake valve 3 is in a closed state. When the second part 1232 abuts against button 31, the lower end of mounting hole 2111 connects to connecting port 2112, so that cavity 221 connects to air passage 231.

[0040] like Figure 1 , Figure 2 , Figure 10 , Figure 12 As shown, the bottom cover 23 includes a bottom plate 232 and two side plates 233. The bottom plate 232 has a first channel 2321 on its end face facing the outer bottle 22. The side plates 233 extend along the length of the outer wall of the outer bottle 22, and the end faces of the side plates 233 facing the outer bottle 22 have a second channel 2331. The first channel 2321 connects the two second channels 2331. The first channel 2321, the two second channels 2331, and the side wall of the outer bottle 22 form an air passage 231. The mounting base 211 has an annular groove 2113 and a slot 2114. The upper end of the outer bottle 22 is fixedly mounted on the mounting base 211. The annular groove 2113 and the upper end of the side plate 233 are provided with an insert plate 2332 corresponding to the slot 2114. The insert plate 2332 is fixedly installed in the slot 2114. Since there is no sealing element between the side plate 233 and the outer wall of the outer bottle 22, there is a gap between the side plate 233 and the outer wall of the outer bottle 22. When the refrigerant gas is released, it passes through the air passage 231 and has a certain pressure. The refrigerant gas will flow from the air passage 231 to the outside and be released to the outside. The refrigerant gas is safe and non-toxic. After the refrigerant gas is released to the outside, it will not cause harm to the body and has a high safety.
