[0026] The following further describes the utility model of the present application in detail with reference to the accompanying drawings and specific embodiments. In order to clearly and completely describe the technical solution, the following embodiments are selected for description; based on the content recorded in the present application, other embodiments obtained without creative labor fall within the protection scope of the present utility model.

[0027] In the following embodiments, it should be noted that the orientation or positional relationships in terms of "upper", "lower", "left", "right", "inner", "outer", "top / bottom", etc. in the terms are all based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of clearly describing the present embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, so it cannot be understood as a limitation to the present application.

[0028] As Figures 1 - 10 shown, a specific embodiment of the present utility model is a replaceable vacuum pressing multi-layer protection essence packaging bottle, including an outer bottle assembly 1, a replaceable inner container 2 and a base 5. The replaceable inner container 2 is nested and installed inside the outer bottle assembly 1, and the base 5 can be snap-connected to the lower part of the outer bottle assembly 1.

[0029] Among them, the replaceable inner liner 2 is composed of an inner bottle body 203, a piston 202, a fixed cover 206, a liquid outlet pump head 205 and a gland 201. The piston 202 is installed at the upper part of the inner bottle body 203, the gland 201 is installed at the top of the inner bottle body 203, and the liquid outlet pump head 205 is fixedly installed at the lower part of the inner bottle body 203. The piston 202 is connected to the gland 201. When the gland 201 is pressed down, the piston 202 will move downward along the inner wall of the inner bottle body 203, thereby squeezing the essence liquid and making it flow out from the liquid outlet pump head 205. The fixed cover 206 is used to fixedly install the liquid outlet pump head 205 at the lower part of the inner bottle body 203, ensuring the firm connection and sealing between the liquid outlet pump head 205 and the inner bottle body 203.

[0030] The outer bottle assembly 1 is composed of an outer bottle body 102 and a middle bottle body 101. A limit block 103 is arranged on the outer side of the upper part of the middle bottle body 101, and a limit groove 104 is arranged on the inner side of the upper part of the outer bottle body 102. The limit block 103 can match with the limit groove 104 to ensure the correct position of the middle bottle body 101 in the outer bottle body 102 and tight assembly. The outer bottle body 102 and the middle bottle body 101 are ultrasonically welded and fixed together. Ultrasonic welding is a method that uses the energy generated by ultrasonic vibration to melt the contact surfaces of two plastic parts and weld them together under pressure. In the outer bottle assembly 1, ultrasonic welding is used to fix the connection between the outer bottle body 102 and the middle bottle body 101. This method not only ensures the firmness of the connection but also avoids the problems that may be brought by traditional screws or adhesives (such as loosening, leakage or pollution).

[0031] To prevent the leakage of the essence liquid, an inner cover 3 is also arranged in the base 5. A convex column 301 is arranged on the inner cover 3. A second liquid outlet 105 is arranged at the bottom of the outer bottle body 102, and a first liquid outlet 106 is arranged at the bottom of the middle bottle body 101. The diameter of the first liquid outlet 106 is smaller than that of the second liquid outlet 105. Further, the convex column 301 of the inner cover 3 matches with the second liquid outlet 105 at the bottom of the outer bottle body 102 to seal the second liquid outlet 105 and prevent the essence liquid from leaking from the bottom.

[0032] Specifically, as Figure 10 shown, a leak-proof plug 302 and a plurality of limit posts 303 are arranged in the convex column 301 of the inner cover 3. The limit posts 303 are arranged around the leak-proof plug 302. The leak-proof plug 302 corresponds to the first liquid outlet 106. The inner diameters of the four limit posts 303 match with the outer diameter of the second liquid outlet 105, so that the second liquid outlet 105 is stably limited in the inner cover 3, and the liquid at the first liquid outlet 106 will not flow out, ensuring good sealing performance.

[0033] To increase the stability of the bottle body, a counterweight 4 is also provided inside the base 5. The counterweight 4 enhances the weight at the bottom of the packaging bottle to improve the stability of the packaging and its anti-tipping ability. The annular base 501 is located at the lower part of the base 5, and its outer diameter is larger than the outer diameter of the outer bottle body 102. The main function of this design is to increase the contact area between the packaging bottle and the placement surface, thereby further improving the stability of the packaging and having a certain anti-slip effect.

[0034] To facilitate the flow of the liquid, as Figure 8 and Figure 9 shown, the bottoms of the middle bottle body 101 and the outer bottle body 102 are in a conical structure, and the surface of the outer bottle body 102 is provided with anti-slip corrugations to increase the roughness of the surface of the outer bottle body 102, making it more stable for users to hold the packaging bottle.

[0035] The pressing cap 201 also has an anti-slip design and a limiting structure to improve the convenience of user operation. Preferably, a limiting protrusion 207 is provided on the pressing cap 201, and a horizontal limiting strip 208 is provided on the inner wall of the top of the inner bottle body 203. When the two cooperate, a mechanical locking structure is formed. When the pressing cap 201 is rotated to a specified angle, the horizontal limiting strip 208 abuts against the limiting protrusion 207. At this time, the pressing cap 201 cannot be pressed down, preventing the user from accidentally pressing the essence without correctly rotating the pressing cap 201, avoiding unnecessary waste and possible leakage risks. When using the essence, the user needs to first rotate the pressing cap 201 to the specified angle so that the limiting protrusion 207 abuts against the horizontal limiting strip 208. At this time, due to the mechanical locking effect, the pressing cap 201 cannot be further pressed down, thus avoiding the leakage of the essence caused by misoperation. When the user needs to take out the essence, just rotate the pressing cap 201 in the reverse direction to the unlocking position, and then the pressing cap 201 can be easily pressed down to squeeze out the essence.

[0036] As Figure 3 、 Figure 6 and Figure 8As shown, the bottom of the liquid outlet pump head 205 in the present application has an internal screw thread, and the outer periphery of the top of the first liquid outlet 106 of the middle bottle body 101 has an external screw thread. The liquid outlet pump head 205 surrounds the top of the first liquid outlet 106 of the middle bottle body 101 through the internal screw thread, so as to enable the essence liquid to flow from the liquid outlet pump head 205 into the first liquid outlet 106. In order to increase the sealing performance between the middle bottle body 101 and the inner bottle body 203, a sealing ring 204 is also provided between the liquid outlet pump head 205 and the inner bottle body 203. In addition, an internal thread 209 and a through hole 210 are provided on the fixing cover 206, an external thread 211 is provided at the lower part of the inner bottle body 203, and the internal thread 209 on the fixing cover 206 matches the external thread 211 on the inner bottle body 203. By rotating the fixing cover 206, the tight connection and fixation between the inner bottle body 203 and the fixing cover 206 can be achieved; the through hole 210 provided on the fixing cover 206 allows the liquid outlet pump head 205 to protrude, facilitating the user to extract the liquid in the inner bottle body 203 by pressing the pump head.

[0037] The packaging bottle structure of the present application can effectively isolate the influence of air and the external environment on the essence liquid, ensure the stability and activity of the essence liquid during long-term storage, and extend the shelf life of the product. Moreover, the packaging bottle of the present application has a replaceable core structure. While the middle bottle body and the outer bottle body provide multiple protections, they can also be reused, effectively reducing the use cost.

[0038] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any minor modifications, equivalent replacements, and improvements made to the above embodiments based on the technical essence of the present utility model shall be included in the protection scope of the technical solution of the present utility model.
