Abstract
Description
Technical Field
[0001] This utility model relates to the field of freeze-dried essence packaging technology, specifically to a solid-liquid mixed structure. Background Technology
[0002] Freeze-dried serums are solid serums produced using freeze-drying technology, such as freeze-dried spheres, which can retain highly active ingredients during long-term storage. Traditionally, freeze-dried serums are packaged in a single bottle, such as a vial, with the bottle sealed by a stopper. The bottle contains the freeze-dried spheres, which are mixed with a solvent to form a skincare solution before use.
[0003] The existing packaging structure requires removing the sealing stopper and injecting liquid into the bottle mouth during use. It is compatible with single-use bottles with a single-use liquid volume, allowing all the liquid in the single-use bottle to be squeezed into the vial for mixing with the lyophilized bulbs. However, it is difficult to adapt to reusable bottles with large liquid volumes, and the amount of liquid injected cannot be controlled. Moreover, the operation requires removing the sealing stopper to inject liquid, then replacing the sealing stopper to mix, and finally removing the sealing stopper again to pour out the mixture, which is quite cumbersome. In addition, since the mixture is still poured out from the vial mouth, it is difficult to control the flow rate of the liquid. Utility Model Content
[0004] This invention addresses the technical problems of poor compatibility and inconvenience in using existing freeze-dried essence packaging with liquid bottles. It proposes a solid-liquid hybrid structure that can be used with large-capacity liquid bottles, has good compatibility, controllable liquid inlet and outlet, and is easy to use.
[0005] The technical solution of this utility model:
[0006] A solid-liquid mixing structure includes a negative pressure straw, a rubber sleeve at a first end of the straw, a flow port at a second end of the straw, an isolation mesh inside the straw, and a solid substance stored inside the straw between the rubber sleeve and the isolation mesh. In the stored state, the flow port is sealed by an end cap. In use, the end cap can be opened, and the rubber sleeve can be pressed and released to draw in liquid through the flow port of the negative pressure straw to mix with the solid substance.
[0007] Furthermore, the first end of the negative pressure straw is also provided with a sealing layer. In the storage state, the first end of the negative pressure straw is sealed by the sealing layer, and the solid is stored between the sealing layer and the isolation mesh. The mesh size of the isolation mesh is smaller than the outline size of the solid. In use, the seal of the sealing layer can be broken, and the rubber sleeve is detachably installed on the first end of the negative pressure straw.
[0008] Furthermore, the inner wall of the rubber sleeve is provided with an installation part, and the rubber sleeve is installed on the first end of the negative pressure suction tube through the installation part; a puncture end is also formed on the installation part, and the sealing layer is broken through the puncture end when the rubber sleeve is installed.
[0009] Optionally, the sealing layer is aluminum foil.
[0010] Optionally, the sealing layer is a sealing plug.
[0011] Optionally, the sealing layer is a bidirectional valve core, which includes multiple elastic valve discs. In the storage state, the multiple elastic valve discs are on the same plane and their edges are fitted together to form a seal. In use, the multiple elastic valve discs can be opened inward or outward under the action of external force.
[0012] Furthermore, the second end of the negative pressure straw is formed into a funnel shape, and the smaller diameter end of the funnel shape forms the flow port.
[0013] Furthermore, the edge of the isolation net is embedded in the inner wall of the negative pressure straw; or, the isolation net and the negative pressure straw are integrally formed.
[0014] Furthermore, a thinning line is provided at the connection between the end cap and the negative pressure suction tube.
[0015] Furthermore, the end cap extends straight along the length of the negative pressure straw for a certain length, and multiple protrusions are formed on the outer peripheral surface of the extended section of the end cap.
[0016] By adopting the above technical solution, the solid-liquid mixing structure provided by this utility model has the following beneficial effects compared with the prior art: The solid-liquid mixing structure of this utility model contains a solid material inside a negative pressure straw, a rubber sleeve at the first end of the negative pressure straw, and a flow port at the second end. This allows for liquid aspiration via the negative pressure straw, enabling its use with large-volume liquid bottles. The amount of liquid aspirated can be controlled by changing the pressing pressure or the volume of the rubber sleeve. Furthermore, the mixed liquid can be discharged by pressing to release the rubber sleeve, and the discharge volume and speed can be controlled. In addition, the operation of aspirating and discharging liquid by pressing and releasing the rubber sleeve is very convenient. Attached Figure Description

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0032] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0033] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.
[0034] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0035] Example 1:
[0036] like Figure 1-6As shown, this embodiment provides a solid-liquid mixing structure, which includes a negative pressure straw 1. The first end of the negative pressure straw 1 is sealed with a rubber sleeve 2, which is made of rubber, compressible, and has a certain compression space inside. The second end of the negative pressure straw 1 forms a flow port 11 for liquid inlet and outlet. An isolation mesh 3 is also provided inside the negative pressure straw 1, which can be positioned near the flow port 11. Further, a solid material 6 is stored inside the negative pressure straw 1 between the rubber sleeve 2 and the isolation mesh 3. The solid material 6 has a certain particle size, such as freeze-dried essence balls, and preferably multiple of them.
[0037] In its storage state, the flow port 11 of the negative pressure straw 1 is sealed by the end cap 4. During use, the end cap 4 can be opened by rotation or breaking. After opening, pressing the rubber sleeve 2 deforms and compresses the internal compression space, expelling some gas from the flow port 11. Then, the flow port 11 is placed in a solvent or other liquid, and the pressure on the rubber sleeve 2 is released. The rubber sleeve 2 rebounds under its own deformation force, creating a negative pressure due to the reduced internal air pressure, allowing liquid to be drawn in from the flow port 11 and mixed with the solid 6 inside the negative pressure straw 1. After mixing for a certain period, pressing the rubber sleeve 2 allows the mixed liquid to be discharged from the flow port 11. Furthermore, this embodiment uses an isolation net 3 to prevent the solid 6 from falling out of the flow port 11 during liquid suction, and also to prevent the solid 6 from escaping before dissolving, ensuring its complete dissolution.
[0038] Thus, the solid-liquid mixing structure provided in this embodiment, compared with the prior art, includes a freeze-dried bulb or other solid material 6 inside the negative pressure straw 1, a rubber sleeve 2 at the first end of the negative pressure straw 1, and a flow port 11 at the second end of the negative pressure straw 1. This allows for liquid aspiration via the negative pressure straw 1, enabling use not only with small-capacity liquid bottles but also with large-volume liquid bottles. The amount of liquid aspirated can be controlled by changing the pressing pressure or the volume of the rubber sleeve 2. Furthermore, the mixed liquid can be discharged by pressing to release the rubber sleeve 2, allowing for control of the discharge volume and speed. Moreover, the operation of aspirating and discharging liquid by pressing and releasing the rubber sleeve 2 is very convenient.
[0039] like Figure 1As shown, in this embodiment, a sealing layer 5 is also provided at the first end of the negative pressure straw 1. In the storage state, the first end of the negative pressure straw 1 is sealed by the sealing layer 5, and the solid 6 is stored between the sealing layer 5 and the isolation mesh 3. When in use, the seal of the sealing layer 5 can be broken. Further, in this embodiment, the rubber sleeve 2 is detachably installed at the first end of the negative pressure straw 1. For example, an external thread is provided at the first end of the negative pressure straw 1, and an installation part 21 is provided on the inner wall of the rubber sleeve 2. The installation part 21 can be made of plastic, and the rubber sleeve 2 is integrally formed or bonded to this installation part 21. An internal thread is provided on the installation part 21, so that the rubber sleeve 2 can be threaded onto the negative pressure straw 1 through the installation part 21, and the threaded connection can ensure a certain degree of sealing. In this way, the rubber sleeve 2 is set to be detachably installed. When packaging the product, one rubber sleeve 2 and multiple negative pressure straws 1 can be set, and one rubber sleeve 2 can be adapted to multiple negative pressure straws 1 for multiple uses.
[0040] The sealing layer 5 is preferably aluminum foil. In use, the aluminum foil is first removed, and then the rubber sleeve 2 is installed. Alternatively, more preferably, such as... Figure 2 , 5 As shown, in this embodiment, a flange 22 is formed inward on the mounting part 21, and a piercing end 23 is formed protruding on the flange 22. The center of the piercing end 23 is hollow, so that when using it, there is no need to remove the aluminum foil. The rubber sleeve 2 can be directly installed, and the aluminum foil can be pierced by the piercing end 23 on the rubber sleeve 2, making it more convenient to use.
[0041] like Figure 1 , 5 As shown, in this embodiment, the second end of the negative pressure straw 1 is formed into a flared opening, with the smaller diameter end of the flared opening forming the flow port 11, which is sealed by the end cap 4. The larger diameter end of the flared opening is integrally connected to the main body of the negative pressure straw 1, thereby making the flow port 11 smaller and easier to control the amount of liquid entering and exiting. Moreover, the negative pressure straw 1 and the end cap 4 are integrally formed into a baseball bat shape, which is aesthetically pleasing. Preferably, the amount of liquid drawn in can be ensured by controlling the pressure applied to the rubber sleeve 2 or by setting the size of the rubber sleeve 2, so that the liquid level after being drawn in is maintained at a certain height, for example, in the middle of the main body of the negative pressure straw 1, without entering the rubber sleeve 2, thus reducing contamination of the rubber sleeve 2. In addition, an additional placement seat (not shown in the figure) can be configured. This placement seat is adapted to the flared opening of the negative pressure straw 1, so that after the negative pressure straw 1 draws in liquid, it can be placed on this placement seat for mixing without holding it by hand. Moreover, the negative pressure straw 1 is in a vertical state, so the liquid will not flow into the rubber sleeve 2.
[0042] like Figure 5-6As shown, the mesh size 31 of the isolation net 3 is smaller than the outline size of the solid object 6. For example, when the solid object 6 is a freeze-dried ball, the mesh size 31 can be a round hole, and the diameter of the round hole is smaller than the diameter of the freeze-dried ball. The mesh size 31 of the isolation net 3 can be set as needed. For example, in other embodiments, it can also be set as an elongated hole, with a longer length but a width smaller than the diameter of the freeze-dried ball, so that it can facilitate the flow of liquid while blocking and isolating. When installing the isolation net 3, a step 12 can be formed by recessing the inner wall of the negative pressure suction tube 1. The edge of the isolation net 3 is embedded in the inner wall of the negative pressure suction tube 1. The isolation net 3 is installed on the inner wall of the negative pressure suction tube 1 by means of bonding, snap-fitting, etc., or the isolation net 3 can also be integrally formed with the negative pressure suction tube 1 by injection molding. In addition, Figure 5 The installation height of the isolation net 3 shown is for illustrative purposes only; in other embodiments, it can be set closer to the flow port 11.
[0043] For ease of use, such as Figure 1 , 3 As shown, in this embodiment, a thinning line 13 is provided at the connection between the end cap 4 and the negative pressure straw 1. The wall thickness at the thinning line 13 is small, so that the end cap 4 can be broken at this point when it is bent. To make it easier to break, this embodiment also provides that the end cap 4 extends straight along the length of the negative pressure straw 1 to increase the lever arm, and multiple protrusions 41 are formed on the outer circumferential surface of the extended section of the end cap 4 for anti-slip, so that the end cap 4 can be broken more easily. Of course, in other embodiments, the end cap 4 can also be a threaded cap.
[0044] As can be seen from the above, the solid-liquid mixing structure provided in this embodiment can be used with large-capacity liquid bottles, has good compatibility, and allows for controllable liquid inlet and outlet, and is also very convenient to use.
[0045] Example 2:
[0046] The main difference between this embodiment and Embodiment 1 lies in the structure of the sealing layer 5.
[0047] like Figure 7-9 As shown, the sealing layer 5 in this embodiment is a sealing plug. In the storage state, the sealing plug seals the first end of the negative pressure suction tube 1. In use, the sealing plug can be pulled out and the rubber sleeve 2 can be installed; or the sealing plug can be punctured directly by the puncture end on the rubber sleeve 2. Preferably, this embodiment also provides a thinning part 52 in the middle of the sealing plug. The thickness of the thinning part 52 is small, making it easier to puncture. A thinning groove 521 can also be provided on the thinning part 52 to make it even easier to puncture.
[0048] Example 3:
[0049] The main difference between this embodiment and embodiments one and two lies in the different installation structures of the sealing layer 5 and the rubber sleeve 2.
[0050] like Figure 10-12 As shown, the sealing layer 5 in this embodiment is a bidirectional valve core, which includes multiple elastic valve flaps 53, such as four elastic valve flaps 53 shown in the figure. In the storage state, the multiple elastic valve flaps 53 are approximately located in the same horizontal plane, and the edges of each elastic valve flap 53 adhere to each other under their own elasticity to form a seal. In use, a rubber sleeve 2 is installed on the negative pressure suction tube 1. In this embodiment, the rubber sleeve 2 does not need to be provided with a puncture end. By pressing the rubber sleeve 2, the multiple elastic valve flaps 53 can open inward toward the negative pressure suction tube 1 under the action of gas pressure. After releasing the pressing pressure of the rubber sleeve 2, the multiple elastic valve flaps 53 can also open outward toward the rubber sleeve 2 to aspirate liquid. Thus, the operation and use are more convenient.
[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
