[0038] [Example 1]

[0039] like Figure 1-Figure 4 As shown, this embodiment discloses a specific implementation of a multi-bin material bottle with high sealing performance, including a first barrel structure and a second barrel structure, wherein, as Figure 3-Figure 4 As shown, the first barrel structure includes an outer barrel 1a with a first accommodating space, an inner barrel 1b with a second accommodating space, a first sealing ring 1d and a gland 1h, wherein the outer barrel 1a has a first opening, through which the first accommodating space is connected to the outside of the outer barrel 1a. The inner barrel 1b has a second opening, through which the second accommodating space is connected to the outside of the inner barrel 1b, and the inner barrel 1b is located in the first accommodating space, so that the outer barrel 1a can protect the inner barrel 1b from damage caused by external collision. The gland 1h is connected to the first opening, and the first end of the gland 1h (i.e. Figure 3The right end of the gland 1h in the gland 1h) is sealed by a pierceable sealing membrane 1f, and the second end of the gland 1h (i.e. Figure 3 The left end of the gland 1h in the outer tube presses the first sealing ring 1d tightly at the second opening, and the second accommodating space, the first sealing ring 1d, the gland 1h and the pierceable sealing film 1f together constitute a high barrier compartment 1c for storing freeze-dried powder. In this embodiment, the outer tube 1a and the inner tube 1b are coaxially arranged cylindrical structures and are open at one end, which are the first opening of the outer tube 1a and the second opening of the inner tube 1b, respectively, and the pierceable sealing film 1f is aluminum foil.

[0040] The second barrel structure includes a body and a third sealing ring 2e disposed on the body. The body is provided with a liquid compartment 2d for storing liquid. In this embodiment, the liquid compartment 2d is used to store essence. The body is sleeved on the outer barrel 1a and the gap between the outer barrel 1a and the body is sealed by the second sealing ring 1g. The third sealing ring 2e presses the pierceable sealing film 1f onto the gland 1h. Specifically, in this embodiment, the body includes a connecting barrel 2a with openings at both ends. The inner wall of the connecting barrel 2a is provided with an installation step 2j. The two ends of the aforementioned third sealing ring 2e respectively abut against the step surface of the installation step 2j and the pierceable sealing film 1f.

[0041] In this embodiment, a multi-compartment structure is used to simultaneously store freeze-dried powder and essence. At the same time, in order to meet the high sealing requirements for storing freeze-dried powder, a multi-compartment structure is used to simultaneously store freeze-dried powder and essence. At the same time, in order to meet the high sealing requirements for storing freeze-dried powder, a second sealing ring 1g is used to prevent water vapor from outside the multi-compartment dosage bottle from passing through the structural gap between the outer cylinder 1a and the main body and the pierceable sealing film 1f to enter the high-barrier compartment 1c for storing freeze-dried powder. A third sealing ring 2e is used to prevent water vapor in the liquid compartment 2d from passing through the pierceable sealing film 1f to enter the high-barrier compartment 1c for storing freeze-dried powder. Then, a first sealing ring 1d is used in the gap between the pressure cover 1h and the inner cylinder 1b to prevent water vapor from outside from passing through the structural gap between the outer cylinder 1a and the main body and the gap between the pressure cover 1h and the inner cylinder 1b to enter the high-barrier compartment 1c for storing freeze-dried powder. Through the above-mentioned two sealing structure designs, the high-barrier compartment 1c has a higher sealing performance, which can prevent the freeze-dried powder from getting damp and extend the storage time of the freeze-dried essence.

[0042] More preferably, since the moisture and oxygen permeability of glass is zero, the material of the inner tube 1b is glass, which further improves the sealing performance of the high-barrier chamber 1c.

[0043] [Example 2]

[0044] Example 2 discloses another specific implementation of a multi-bin material bottle with high sealing performance. Example 2 is based on the example. Figure 3-Figure 4As shown, the gland 1h of embodiment 2 is interference fit with the inner wall of the inner tube 1b. By designing the gland 1h and the inner wall of the inner tube 1b to be interference fit, the interference fit portion 1e between the gland and the inner tube is shown. Figure 3 , strengthen the sealing between the outer wall of the pressure cover 1h and the inner wall of the inner tube 1b, better prevent the external water vapor from entering the high barrier chamber 1c for storing freeze-dried powder through the structural gap between the outer tube 1a and the main body and the gap between the pressure cover 1h and the inner tube 1b, and improve the sealing performance of the high barrier chamber 1c.

[0045] [Example 3]

[0046] Example 3 discloses another specific implementation of a multi-bin material bottle with high sealing performance. Example 3 is based on Example 1 or 2. Figure 1-Figure 4 As shown, the main body of Example 3 also includes a movable cylinder 2b inserted into the third sealing ring 2e, and the movable cylinder 2b can move along its own axial direction. The movable cylinder 2b is provided with a liquid tank 2d, and the end of the movable cylinder 2b close to the puncturable sealing membrane 1f is an open end, and the liquid tank 2d is connected to the outside of the movable cylinder 2b through the end of the movable cylinder 2b close to the puncturable sealing membrane 1f.

[0047] like Figure 3-Figure 4 As shown, the second barrel structure also includes a puncturing portion 2f for puncturing the puncturable sealing membrane 1f. The puncturing portion 2f is arranged at the opening end of the movable barrel 2b. In this embodiment, the puncturing portion 2f is a sharp corner formed by two arc-shaped surfaces, which can puncture the puncturable sealing membrane 1f.

[0048] When the piercing structure pierces the pierceable sealing membrane 1f, the liquid chamber 2d is connected with the high barrier chamber 1c, thereby mixing the freeze-dried powder with the essence.

[0049] In order to prevent the liquid in the liquid tank 2d from flowing into the chamber formed between the connecting tube 2a and the movable tube 2b, the outer wall of the movable tube 2b is interference fit with the third sealing ring 2e, thereby preventing the liquid in the liquid tank 2d from flowing into the chamber formed between the connecting tube 2a and the movable tube 2b through the gap between the movable tube 2b and the third sealing ring 2e.

[0050] More preferably, the body further comprises a first limiting boss 2h and a second limiting boss 2g, wherein the first limiting boss 2h is arranged on the inner wall of the connecting tube 2a, and the second limiting boss 2g is arranged on the outer wall of the movable tube 2b. In this embodiment, the first limiting boss 2h and the second limiting boss 2g are both arranged in an annular shape. When the movable tube 2b is in the first limit position, the first limiting boss 2h and the second limiting boss 2g are abutted against each other, and there is a certain distance between the piercing portion 2f and the pierceable sealing film 1f. At this time, since there is a certain distance between the piercing portion 2f and the pierceable sealing film 1f, it can be ensured that the pierceable sealing film 1f is not broken, and the high barrier chamber 1c and the liquid chamber 2d are in a separated state; when the movable tube 2b is in the second limit position, the first limiting boss 2h and the second limiting boss 2g are separated, the piercing portion 2f pierces the pierceable sealing film 1f, and the liquid chamber 2d is connected with the high barrier chamber 1c.

[0051] In other embodiments, at least one of the first limiting boss 2h and the second limiting boss 2g is annular, for example: the first limiting boss 2h is annular and the second limiting boss 2g is a single block structure or a plurality of block structures distributed along the circumferential direction, the second limiting boss 2g is annular and the first limiting boss 2h is a single block structure or a plurality of block structures distributed along the circumferential direction. Of course, the first limiting boss 2h and the second limiting boss 2g can also be a single block structure or a plurality of block structures distributed along the circumferential direction. As long as it is ensured that when the movable cylinder 2b is in the first extreme position, the first limiting boss 2h can offset the second limiting boss 2g, it will not be repeated here.

[0052] Better, such as Figure 3 As shown, the main body also includes a limit channel arranged on the outer wall of the movable cylinder 2b, and a limit switch 2c rotatably connected to the connecting cylinder 2a. Specifically, as shown in FIG. Figure 6 As shown, the extending direction of the limiting channel is parallel to the axial direction of the movable cylinder 2b, and the limiting channel is formed by two ribs 2i arranged on the outer wall of the movable cylinder 2b, and the two ribs 2i are parallel to each other.

[0053] like Figure 3 and Figure 5 As shown, the limit switch 2c includes a switch handle 2c2 and a limit plate 2c1, and one end of the switch handle 2c2 extends into the connecting tube 2a and is provided with the limit plate 2c1.

[0054] When the limit switch 2c is at the first angle, the plane where the limit plate 2c1 is located has an angle with the extension direction of the limit channel, and the limit plate 2c1 prevents the puncture part 2f from moving toward the direction of the inner tube 1b, so that there is a certain distance between the puncture part 2f and the puncturable sealing membrane 1f, that is, the limit plate 2c1 will abut against one end of the rib plate 2i, preventing the puncture part 2f from continuing to move toward the direction of the inner tube 1b, thereby ensuring that the puncturable sealing membrane 1f is not punctured by the puncture part 2f.

[0055] When the limit switch 2c is at the second angle, the plane where the limit plate 2c1 is located is parallel to the extension direction of the limit channel, and the movable cylinder 2b can move toward the inner cylinder 1b along its own axial direction and puncture the puncturable sealing membrane 1f through the puncture portion 2f, that is, the limit plate 2c1 no longer rests against the rib plate 2i, and is located between the two rib plates 2i. At this time, by pushing the movable cylinder 2b to move in the direction of the inner cylinder 1b, the puncture portion 2f can finally puncture the puncturable sealing membrane 1f, so that the high barrier chamber 1c is connected with the liquid chamber 2d.

[0056] The limit switch 2c serves to limit the movement of the movable cylinder 2b and is opened when the high barrier chamber 1c needs to be connected to the liquid chamber 2d, thereby preventing the freeze-dried powder in the high barrier chamber 1c and the liquid in the liquid chamber 2d from being mixed prematurely due to misoperation of the movable cylinder 2b.

[0057] [Example 4]

[0058] Example 4 discloses another specific implementation of a multi-bin material bottle with high sealing performance. Example 4 is based on any one of Examples 1-3, such as Figure 3-Figure 4 As shown, the second barrel structure further includes a feeding head 3, which is disposed at one end of the movable barrel 2b away from the pierceable sealing membrane 1f, and the feeding head 3 is communicated with the liquid bin 2d.

[0059] At least a portion of the cylinder wall at the position of the movable cylinder 2b corresponding to the liquid bin 2d can be deformed by inward pressure. Specifically, the cylinder wall thickness at the deformable position of the movable cylinder 2b is smaller than the cylinder wall thickness at both ends of the movable cylinder 2b, that is, the wall thickness at the deformable position of the movable cylinder 2b is relatively thin, so that it can be deformed inward when subjected to inward squeezing force, thereby squeezing the mixed liquid out of the liquid bin 2d.

[0060] When the freeze-dried essence is needed, the pierceable sealing membrane 1f is first pierced to mix the freeze-dried powder and the essence liquid to form the freeze-dried essence, and then the deformable position of the movable cylinder 2b is squeezed inward to squeeze the freeze-dried essence through the feeding head 3 into the multi-chamber dosage bottle with high sealing performance.

[0061] More preferably, the multi-bin material bottle with high sealing performance also includes a bottle cap 4, which is detachably connected to the feeding head 3, and the bottle cap 4 is provided with a blocking block 4a at the discharge port 3a corresponding to the feeding head 3. When the bottle cap 4 is connected to the feeding head 3, the blocking block 4a blocks the discharge port 3a, thereby achieving sealing of the discharge port 3a. In this embodiment, the bottle cap 4 is threadedly connected to the feeding head 3.

[0062] Of course, in other embodiments, the bottle cap 4 and the feeding head 3 may also be connected by snap-fitting or other methods, which will not be described in detail here.
