[0051] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0052] Especially for cosmetics (or skin care products) that are rich in multiple functional ingredients and have high concentrations, such as essences and eye creams, the functions of existing packaging bottles are too single, and it is difficult to ensure the efficacy and skin feel of the cosmetics.

[0053] The packaging bottle provided in this application is intended to solve the above technical problems of related technologies.

[0054] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above technical problems with specific embodiments. It should be noted that the following implementations can refer to, draw on or combine with each other, and the same terms, similar features and similar implementation steps in different implementations will not be described repeatedly.

[0055] The structural schematic diagram of the packaging bottle 100 is as follows Figures 1 to 5 As shown, it includes: a bottle body 11, a material bin 12, a gas bin 13 and a pressing member 14.

[0056] The bottle body 11 has an internal space, and the bottle body 11 includes a ventilation hole connecting the internal space with the outside.

[0057] The silo 12 is at least partially disposed in the bottle body 11 and is used to contain cosmetics.

[0058] The gas bin 13 is at least partially disposed in the bottle body 11, and includes a bin body 131 containing refrigerant gas, and a valve 132 connected to the bin body 131; there is a gap between the bin 12 and the bottle body 11 to form an air flow channel; the pressure of the refrigerant gas is greater than the atmospheric pressure.

[0059] The pressing piece 14 is arranged on the side of the material bin 12 facing the gas bin 13; the pressing piece 14 includes a through hole 1421, and the size of the through hole 1421 along the axial direction perpendicular to the bottle body 11 gradually decreases in the direction approaching the material bin 12; the through hole 1421 is constructed so that when the material bin 12 and the gas bin 13 are relatively close, the hole wall of the through hole 1421 presses the valve 132 to release the refrigerant gas in the bin body 131, so that the refrigerant gas cools the cosmetics in the material bin 12 through the air flow channel.

[0060] In the embodiment of the present application, refrigerant gas is contained in the gas bin 13, and a gap is provided between the material bin 12 and the bottle body 11 to form an air flow channel, which is connected to the outside via the ventilation hole, and the pressing piece 14 is provided on the side of the material bin 12 facing the gas bin 13, and the pressing piece 14 is constructed to press the valve 132 of the gas bin 13 to release the refrigerant gas in the gas bin 13 when the material bin 12 and the gas bin 13 are relatively close, so as to rapidly reduce the pressure of the refrigerant gas and absorb a large amount of heat, so that the refrigerant gas cools the cosmetics in the material bin 12 via the air flow channel, thereby better exerting the efficacy of the cosmetics and improving the skin feel of the cosmetics.

[0061] In the embodiment of the present application, by providing the through hole 1421, not only can the valve 132 be opened by pressing the hole wall of the through hole 1421, but also the refrigerant gas released from the gas bin 13 can be transmitted to the air flow channel between the bin 12 and the bottle body 11 through the through hole 1421, thereby achieving cooling of the bin 12.

[0062] Furthermore, since the through hole 1421 is open, the valve 132 can be smoothly placed in the through hole 1421 , and the valve 132 can be pressed by the hole wall of the through hole 1421 .

[0063] The packaging bottle 100 in the embodiment of the present application is suitable for various cosmetics (or skin care products) such as essence, eye cream, face cream, toner, lotion, primer, sunscreen, etc. In particular, cosmetics such as essence that are rich in multiple functional ingredients and have high concentrations are particularly suitable for use as a single-use essence bottle.

[0064] See also Figures 2 to 5 Optionally, in some embodiments, the pressing member 14 includes a spiral sleeve 141 and a pressing portion 142 fixedly connected to the spiral sleeve 141 ; the spiral sleeve 141 and the bottle body 11 are relatively movable along the axial direction of the bottle body 11 .

[0065] The packaging bottle 100 further comprises a base 15 disposed on a side of the gas bin 13 away from the material bin 12; a portion of the spiral sleeve 141 is disposed in the bottle body 11, and another portion is connected to the base 15 via a thread; the base 15 and the bottle body 11 can rotate relative to each other.

[0066] The base 15 is configured to drive the spiral sleeve 141 to move toward the gas chamber 13 when rotating in a plane perpendicular to the axial direction of the bottle body 11 in a first direction, so that the pressing portion 142 presses the valve 132 .

[0067] The spiral sleeve 141 and the bottle body 11 can move relative to each other along the axial direction of the bottle body 11 , but cannot rotate relative to each other.

[0068] The first direction may be clockwise or counterclockwise, which is not limited here.

[0069] Optionally, in some embodiments, the base 15 may be provided with a first internal thread 151 , and the pressing member 14 may be provided with a first external thread 143 matching the first internal thread 151 , and the base 15 and the pressing member 14 are rotatably connected via the first internal thread 151 and the first external thread 143 .

[0070] By rotating the base 15 in a first direction, the base 15 is moved away from the gas chamber 13 (eg Figure 2 The spiral sleeve 141 and the bottle body 11 can move relative to each other along the axial direction of the bottle body 11, and cannot rotate relative to each other along the circumferential direction of the bottle body 11, so that the base 15 drives the pressing member 14 to move toward the gas chamber 13 (such as Figure 2 The pressing portion 142 moves downward in the middle of the gas chamber 13, so that the pressing portion 142 presses the valve 132 to release the refrigerant gas in the gas chamber 13.

[0071] See also Figures 3 to 5Optionally, in some embodiments, the bottle body 11 includes a first sub-segment 111 close to the base 15 and a second sub-segment 112 arranged on a side of the first sub-segment 111 away from the base 15 ; the outer diameter of the second sub-segment 112 is greater than the outer diameter of the first sub-segment 111 .

[0072] The base 15 is sleeved on the periphery of the first sub-segment 111 and abuts against the end surface of the second sub-segment 112 along the axial direction of the bottle body.

[0073] With such arrangement, during the process of rotating the base 15, the base 15 and the bottle body 11 will only rotate relative to each other, and basically no relative movement along the axial direction of the bottle body will occur, so that the second sub-segment 112 of the bottle body 11 can be held with one hand and the base 15 can be rotated with the other hand, so that the base 15 drives the pressing piece 14 to move toward the gas chamber 13 via the first internal thread 151 and the first external thread 143, which is convenient for users to operate and has a better operating feel.

[0074] See also Figures 3 to 5 Optionally, in some embodiments, at least one guide groove 16 is provided on the inner side of the bottle body 11 , and the guide groove 16 extends along the axial direction of the bottle body 11 .

[0075] At least one guide member 17 is disposed on the outer side of the spiral sleeve 141 , and the guide member 17 is movably disposed in the guide groove 16 .

[0076] Through the cooperation between the guide groove 16 and the guide member 17 , it is possible to realize that the spiral sleeve 141 and the bottle body 11 can move relative to each other along the axial direction of the bottle body 11 , but cannot rotate relative to each other along the circumferential direction of the bottle body 11 .

[0077] See also Figure 4 and Figure 7 Optionally, in some embodiments, the guide member 17 includes a main body 171 and an end portion 172 disposed on a side of the main body 171 close to the silo 12 .

[0078] The main body 171 extends along the axial direction of the bottle body 11 ; and the width of the end portion 172 along the axial direction perpendicular to the bottle body 11 gradually decreases in a direction approaching the silo 12 .

[0079] Since the end portion 172 is in a pointed shape, it can play a guiding role, thereby facilitating the smooth installation of the pressing member 14 in the bottle body 11 .

[0080] See also Figure 6Optionally, in some embodiments, the through hole 1421 includes a first hole segment 1421a and a second hole segment 1421b connected along the axial direction of the bottle body 11; the size of the first hole segment 1421a along the axial direction perpendicular to the bottle body 11 is larger than the size of the second hole segment 1421b along the axial direction perpendicular to the bottle body 11; the connection between the hole wall of the first hole segment 1421a and the hole wall of the second hole segment 1421b is constructed to press the valve 132 when the spiral sleeve 141 moves toward the gas chamber 13.

[0081] Since the aperture of the first hole segment 1421 a is larger than that of the second hole segment 1421 b , a step can be formed at the connection between the hole wall of the first hole segment 1421 a and the hole wall of the second hole segment 1421 b , and the step can realize stable pressing of the valve 132 .

[0082] Optionally, in some other feasible embodiments, the hole wall of the through hole 1421 may be a conical surface.

[0083] Such a configuration not only facilitates the smooth placement of the valve 132 in the through hole 1421 and enables the valve 132 to be pressed by the hole wall of the through hole 1421 , but also facilitates the processing and manufacturing of the through hole 1421 , thus having a cost advantage.

[0084] See also Figure 3 and Figure 6 Optionally, in some embodiments, the pressing portion 142 may further include a base portion 1422 connected to the inner wall of the spiral sleeve 141 , and the base portion 1422 is disc-shaped; the through hole 1421 penetrates the base portion 1422 along the axial direction of the bottle body 11 .

[0085] Since the structural strength of the base portion 1422 is relatively large, the pressing member 14 is less likely to deform, thereby improving the reliability of the packaging bottle 100 .

[0086] Optionally, in some embodiments, the pressing portion 142 may further include a protruding portion provided on one side of the base portion 1422 , and the through hole 1421 passes through the base portion 1422 and the protruding portion.

[0087] With such a configuration, it is not necessary to configure the base portion 1422 to be too thick to ensure the depth of the through hole 1421 , thereby saving the material cost of the pressing member 14 .

[0088] Continue to see Figure 3 and Figure 6 Optionally, in some embodiments, the pressing portion 142 further includes a fixing portion 1423 disposed on a side of the base portion 1422 close to the silo 12 , and the fixing portion 1423 is disposed around the periphery of one end of the silo 12 .

[0089] The fixing portion 1423 is arranged around the silo 12 , which can fix the silo 12 to a certain extent, thereby preventing the silo 12 from tilting and shaking.

[0090] See also Figures 2 to 5 In this embodiment, optionally, the silo 12 includes a main silo body 121 and an extension portion 122 extending from the edge of the main silo body 121; the main silo body 121 is disposed in the internal space of the bottle body 11, and the extension portion 122 is fixed to the first sub-segment 111 of the bottle body 11.

[0091] See also Figures 1 to 5 In some embodiments, the packaging bottle 100 may further include a face cover 18 having a second internal thread, and the second subsection 112 of the bottle body 11 has a second external thread 112a matching the second internal thread.

[0092] The outwardly turned extension portion 122 of the material bin 12 can be used to fix the material bin 12 to the second subsection 112 of the bottle body 11, thereby preventing the material bin 12 from sliding into the inner space of the bottle body 11 and causing the pressing member 14 to accidentally press the valve 132 of the gas bin 13. In addition, the surface cover 18 is sleeved and fixed to the outer side of the second subsection 112 of the bottle body 11, thereby preventing the cosmetics in the material bin 12 from leaking out and preventing the material bin 12 from detaching from the bottle body 11.

[0093] As an example, the refrigerant gas in the embodiment of the present application is a high-pressure refrigerant gas, and the high-pressure refrigerant gas is any one of carbon dioxide, nitrogen, hydrogen, and helium.

[0094] Since the high-pressure refrigerant gas is safe and non-toxic, it will not cause harm to the human body after being released to the outside, and has high safety.

[0095] Among them, the high-pressure refrigerant gas can be understood as a gas with a pressure higher than the atmospheric pressure. When the high-pressure refrigerant gas is released, the pressure drops rapidly, the high-pressure refrigerant gas absorbs a large amount of heat, and the surrounding environment is quickly cooled, thereby cooling the cosmetics in the silo 12.

[0096] In this embodiment, the material of the silo 12 may be a metal material, such as iron, steel, etc. Since metal materials have good thermal conductivity, the cooling effect of the cosmetics in the silo 12 can be better.

[0097] Of course, the material of the silo 12 may also be plastic, which is not limited here.

[0098] In this embodiment, the bottle body 11 may be made of plastic. Since plastic has a good heat insulation effect, the bottle body 11 will not be too cold to affect the user experience.

[0099] The beneficial technical effects brought about by the technical solution provided by the embodiment of the present application include:

[0100] In the embodiment of the present application, refrigerant gas is contained in the gas bin 13, and a gap is provided between the material bin 12 and the bottle body 11 to form an air flow channel, which is connected to the outside via the ventilation hole, and the pressing piece 14 is provided on the side of the material bin 12 facing the gas bin 13, and the pressing piece 14 is constructed to press the valve 132 of the gas bin 13 to release the refrigerant gas in the gas bin 13 when the material bin 12 and the gas bin 13 are relatively close, so as to rapidly reduce the pressure of the refrigerant gas and absorb a large amount of heat, so that the refrigerant gas cools the cosmetics in the material bin 12 via the air flow channel, thereby better exerting the efficacy of the cosmetics and improving the skin feel of the cosmetics.

[0101] In the embodiment of the present application, by providing the through hole 1421, not only can the valve 132 be opened by pressing the hole wall of the through hole 1421, but also the refrigerant gas released from the gas bin 13 can be transmitted to the air flow channel between the bin 12 and the bottle body 11 through the through hole 1421, thereby achieving cooling of the bin 12.

[0102] Furthermore, since the through hole 1421 is open, the valve 132 can be smoothly placed in the through hole 1421 , and the valve 132 can be pressed by the hole wall of the through hole 1421 .
