Description

Technical Field

[0001] The utility model relates to the technical field of freeze-dried facial mask packaging, in particular to a liquid storage box and a mixing component. Background Art

[0002] Freeze-dried facial masks are made by fusing mask concentrate and other ingredients with fabric fibers, then using vacuum freeze-drying technology to sublimate the water, resulting in a solid, dry film. Conventional packaging requires packaging the mask and solvent separately, then mixing them together before use.

[0003] For example, application number "201710612148.4" and titled "A Novel Dual-Chamber Packaging Bag" discloses a packaging structure that divides the packaging bag into a solid compartment and a liquid compartment. The solid compartment can hold a freeze-dried facial mask, while the liquid compartment can hold a solvent such as water. When needed, the virtual seal between the solid and liquid compartments is broken, and the solvent in the liquid compartment can be squeezed into the solid compartment for mixing. In addition, there is also a packaging structure in the prior art that includes a tray inside the freeze-dried facial mask packaging bag. When mixing, the packaging bag is opened and the solvent is poured into the tray for mixing.

[0004] These packaging structures improve user convenience, but both the dual-chamber bag and the tray inside the bag significantly increase product cost. Furthermore, for ordinary bags that are not dual-chamber bags and do not come with a tray, there is still the problem of inconvenience in mixing and using them. Utility Model Content

[0040] Embodiment one:

[0041] like Figure 1-5 As shown, this embodiment provides a liquid storage box 1, which stores a solvent liquid such as water or essence. The liquid storage box 1 can be installed and connected to a target bag body 2 of a product such as a freeze-dried facial mask. The target bag body 2 is destroyed by the bag-breaking structure 15 on the liquid storage box 1, and the solvent liquid is poured into the target bag body 2 to mix and moisten the freeze-dried facial mask.

[0042] Specifically, the liquid storage box 1 includes a box body 11, a liquid reservoir 12, an elastic sealing plate 13, and a central movable rod 14. A connection port 111 is formed on the box body 11, and the connection port 111 is used to be fixedly connected to the target bag 2. The shape of the connection port 111 can be, but is not limited to, circular or rectangular. The liquid reservoir 12 is disposed within the box body 11, and contains a solvent liquid. The liquid reservoir 12 is annular and has an annular opening 121 facing the target bag 2. The elastic sealing plate 13 is disposed on the open side of the liquid reservoir 12 to seal the annular opening 121. A liquid passage hole 131 is also provided in the middle of the elastic sealing plate 13. The central moving rod 14 is arranged in the middle of the liquid tank 12, and a bag breaking structure 15 is also provided on the elastic sealing plate 13. The central moving rod 14 can be driven to move toward the target bag body 2, pressing down the elastic sealing plate 13 to destroy the seal between the elastic sealing plate 13 and the liquid tank 12, and destroying the target bag body 2 through the bag breaking structure 15, and the solvent liquid in the liquid tank 12 can flow into the target bag body 2 through the liquid hole 131.

[0043] Thus, the liquid storage box 1 provided in this embodiment can be connected to a target bag 2. The seal between the liquid reservoir 12 and the elastic sealing plate 13 is broken by the central movable rod 14 in the liquid storage box 1, and the bag surface of the target bag 2 is broken by the bag breaking structure 15, thereby allowing the solvent liquid in the liquid reservoir 12 to flow into the target bag 2. The liquid storage box 1 can be adapted to various target bags 2 without requiring a target bag 2 with a complex structure, thereby reducing the cost of the target bag 2.

[0044] Furthermore, the connection port 111 of the box body 11 can be fixedly connected to the target bag body 2 by bonding. Specifically, an adhesive layer can be provided on the end surface of the connection port 111. The adhesive layer is protected by an easy-tear film 112 before use. When it is needed, the easy-tear film 112 is torn off, and the connection port 111 of the box body 11 is placed downward on the target bag body 2, and then the box body 11 is pressed to bond. Alternatively, in other embodiments, the box body 11 can also be connected to the target bag body 2 by a vacuum adsorption method similar to a suction cup. In addition, the liquid storage box 1 can be connected to the middle or upper left corner, lower left corner, upper right corner, lower right corner, or any other position of the target bag body 2 as needed; in addition, the shape of the box body 11 can also be arbitrarily set. For example, its cross-section can be selected but not limited to a geometric shape such as a circle or a rectangle, or an object shape such as a syringe, a triangular flask, a flask, a capsule, or a fruit shape such as a banana or an apple.

[0045] Furthermore, the central moving rod 14 is slidably arranged in the middle of the liquid tank 12, and is preferably a sliding sealing arrangement. Specifically, the end of the central moving rod 14 away from the elastic sealing plate 13 is formed as a pressing end 141, and a sliding sealing section 142 is formed in the middle of the central moving rod 14. The sliding sealing section 142 is slidably sealed with the inner wall of the liquid tank 12 through a sealing ring; the end of the central moving rod 14 facing the elastic sealing plate 13 is also formed with a downward pressing section 146 for pressing down the elastic sealing plate 13, and the downward pressing section 146 corresponds to the pressure section 135 that presses down the elastic sealing plate 13, and a plurality of circumferentially arranged liquid flow grooves 147 are also formed on the downward pressing section 146, so that the solvent liquid can flow to the liquid flow hole 131.

[0046] Furthermore, the bag-breaking structure 15 is arranged on the side of the elastic sealing plate 13 facing the target bag body 2, and the bag-breaking structure 15 is a cutting tube 151. The cutting tube 151 is formed on the outer periphery of the liquid hole 131, and the height of the cutting tube 151 is set as needed to ensure that the upper bag surface of the target bag body 2 can be punctured. Such a setting can make the solvent liquid flow into the target bag body 2 better. In this embodiment, it is preferred to set the cutting tube 151 to have a notch 152, that is, the cutting tube 151 is not a complete tubular shape, so that when the upper bag surface of the target bag body 2 is punctured, no circular piece will remain. An easy-tear opening 22 is generally provided on the target bag body 2. After the mixing and wetting is completed, the freeze-dried facial mask inside is torn out through the easy-tear opening 22. At this time, the circular piece does not exist, thereby improving the user experience.

[0047] Furthermore, the liquid reservoir 12 includes a connecting tube 122 located on the outer ring and a sealing tube 123 located on the inner ring, as well as a top plate 124 located at the top. The top plate 124, connecting tube 122, and sealing tube 123 form an open chamber for storing the solvent liquid. The top plate 124 can be fixedly connected to the flange on the box body 11. The elastic sealing plate 13 includes a connecting groove 132 located on the outer ring and a sealing groove 133 located on the inner ring, as well as a deformation section 134 located between the connecting groove 132 and the sealing groove 133, and a pressure section 135 located between the connecting groove 132 and the flow hole. The connecting tube 122 is always sealed and engaged with the connecting groove 132. In the initial state, the elastic sealing plate 13 uses the engaging portion of the connecting tube 122 and the connecting groove 132 as a fulcrum, and under the action of its own elasticity, the sealing groove 133 is in sealing contact with the sealing tube 123; when the central moving rod 14 presses down the pressure section 135 of the elastic sealing plate 13, the elastic sealing plate 13 is deformed with the engaging portion of the connecting tube 122 and the connecting groove 132 as a fulcrum, and the sealing tube 123 is detached from the sealing groove 133, and the solvent liquid in the liquid tank 12 can flow out from the gap between the sealing tube 123 and the sealing groove 133.

[0048] In this embodiment, a tear-off film 112 is provided on one side of the connection opening 111 of the box body 11. A virtual seal connecting strip (not shown) is formed between the other side of the box body 11 and the end of the central movable rod 14 away from the target bag 2 to prevent malfunction during transportation or other non-use scenarios. The size of the virtual seal connecting strip can be adjusted as needed to ensure an appropriate opening force.

[0049] The present embodiment provides a liquid storage box 1. When in use, first peel off the easy-tear film 112 at the bottom of the liquid storage box 1, and then install and connect the liquid storage box 1 to the target bag body 2; then hold the liquid storage box 1 to lift the target bag body 2, press the central moving rod 14 in the middle, so that the seal between the liquid tank 12 and the elastic sealing plate 13 is destroyed, and the upper bag surface of the target bag body 2 is destroyed, so that the solvent liquid can flow along the upper surface of the elastic sealing plate 13 to the liquid hole 131, and then flow into the target bag body 2 to mix with the freeze-dried facial mask; after mixing for a certain period of time, tear open the target bag body 2 for use.

[0050] From the above content, it can be seen that the liquid storage box provided in this embodiment can be adapted to the ordinary packaging bags of existing freeze-dried facial masks. When in use, the solvent liquid is mixed into the packaging bag, which is easy to use without the need for a complex and high-cost packaging bag structure.

[0051] Example 2:

[0052] like Figure 6-8 As shown, this embodiment provides a liquid storage box 1, which differs from the first embodiment primarily in its bag-breaking structure 15. Specifically, the bag-breaking structure 15 of this embodiment is a pull ring 153 disposed at the inner end of the central movable rod 14. The middle portion of the pull ring 153 is hingedly or riveted to the inner end of the central movable rod 14. One end of the pull ring 153 is formed with a pull opening 1531. Pulling the pull opening 1531 causes the other end of the pull ring 153 to crush the target bag 2.

[0053] The box body 11, the liquid tank 12 and the elastic sealing plate 13 are formed with a top-down groove 154 corresponding to the pull opening 1531. Due to the presence of the groove 154, the liquid tank 12 and its annular opening 121 are not complete rings. Specifically, the liquid tank 12 includes a connecting rod 125 located on the outer ring, a sealing rod 126 located on the inner ring and a side rod 127 connecting the connecting rod 125 and the sealing rod 126, and also includes a top plate 124 located on the top. The top plate 124, the connecting rod 125, the sealing rod 126 and the side rod 127 form an open chamber, and the open chamber stores the solvent liquid; the elastic sealing plate 13 includes a connecting notch 136 located on the outer ring, a sealing notch 137 located on the inner ring and a notch connecting the connecting notch 136 and the sealing notch. 137 has a side slot 138; in the initial state, the connecting rod 125 is sealed and engaged with the connecting slot 136, the side rod 127 is sealed and engaged with the side slot 138, and the elastic sealing plate 13 makes the sealing slot 137 and the sealing rod 126 sealed and contacted under the action of its own elasticity; when the central moving rod 14 presses down the elastic sealing plate 13, the sealing rod 126 is detached from the sealing slot 137, and the solvent liquid in the liquid tank 12 can flow out from the gap between the sealing rod 126 and the sealing slot 137.

[0054] When in use, first install and connect the liquid storage box 1 to the target bag body 2; then hold the liquid storage box 1 to lift the target bag body 2, insert your fingers into the pull groove 154, pull the pull opening 1531 of the pull ring 153, and destroy the upper bag surface of the target bag body 2 through the other end of the pull ring 153. The end of the other end of the pull ring 153 can be set as a sharp edge, so that the upper bag surface can be destroyed more conveniently; then press the middle center moving rod 14 to destroy the seal between the liquid tank 12 and the elastic sealing plate 13, and the solvent liquid can flow along the upper surface of the elastic sealing plate 13 to the liquid hole 131, and then flow into the target bag body 2 to mix with the freeze-dried facial mask; after mixing for a certain period of time, tear open the target bag body 2 for use.

[0055] From the above content, it can be seen that the liquid storage box provided in this embodiment can also be adapted to the ordinary packaging bags of existing freeze-dried facial masks. When in use, the solvent liquid is mixed into the packaging bag, which is easy to use without the need for a complex and high-cost packaging bag structure.

[0056] Example 3:

[0057] like Figure 9-11 As shown, the liquid storage box 1 provided in this embodiment differs from the first and second embodiments primarily in the bag breaking structure 15. The bag breaking structure 15 in the first and second embodiments requires lifting the target bag 2 after the box body 11 is installed and connected to the target bag 2. This ensures that only the upper surface of the target bag 2 is damaged, without simultaneously damaging the lower surface of the target bag 2. The liquid storage box 1 provided in this embodiment does not require lifting the target bag 2 after the box body 11 is installed and connected to the target bag 2. Instead, the bag can be broken directly after installation and connection.

[0058] Specifically, the end of the central moving rod 14 of this embodiment away from the elastic sealing plate 13 is formed with a threaded connection section 143 threadedly connected to the box body 11, and the outer end surface of the central moving rod 14 is formed with a finger groove 144 for facilitating rotation operation; the middle part of the central moving rod 14 is formed with a rotating sealing section 145, and a sealing ring is provided between the rotating sealing section 145 and the inner wall of the liquid tank 12; the end of the central moving rod 14 facing the elastic sealing plate 13 is formed with a downward pressing section 146, and a plurality of liquid flow grooves 147 are formed on the downward pressing section 146.

[0059] Furthermore, the inner side of the connection port 111 of the box body 11 is circumferentially provided with a plurality of arcuate elastic strips 156. One end of each arcuate elastic strip 156 is fixedly connected to the inner wall of the box body 11 or the elastic sealing plate 13, and the other end, i.e., its distal end, is suspended. In the initial state, the distal end of each arcuate elastic strip 156 protrudes from the end face of the connection port 111 along the axial direction of the box body 11. When the box body 11 is pressed toward the target bag body 2 for installation and connection, the distal end of each arcuate elastic strip 156 is pressed inward and simultaneously moves upward, squeezing the upper bag surface of the target bag body 2 toward the center, causing it to arch. When the box body 11 is installed and connected to the target bag body 2, a raised portion of the upper bag surface within the connection port 111 exists. The end of the central moving rod 14 facing the target bag 2 is further provided with a cutting blade 155, which is located on the bottom side of the elastic sealing plate 13. When the central moving rod 14 is threadedly rotated, the elastic sealing plate 13 is pressed downward, breaking the seal between the elastic sealing plate 13 and the liquid storage tank 12, and the cutting blade 155 rotates to cut through the arched portion of the upper bag surface. In this way, the target bag 2 does not need to be lifted, and the lower bag surface of the target bag 2 will not be cut.

[0060] From the above content, it can be seen that the liquid storage box provided in this embodiment can also be adapted to the ordinary packaging bags of existing freeze-dried facial masks. When in use, the solvent liquid is mixed into the packaging bag, which is easy to use without the need for a complex and high-cost packaging bag structure.

[0061] Example 4:

[0062] This embodiment provides a mixing assembly, including a liquid storage box 1 as described in any of the above embodiments, and also including a target bag body 2, wherein the target bag body 2 is provided with a dry membrane cloth 21 such as a freeze-dried facial mask, and the liquid storage box 1 is provided with a solvent liquid. When in use, the liquid storage box 1 is installed and connected to the target bag body 2, and then mixing is performed to wet the dry membrane cloth 21.

[0063] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
