Description

Technical Field

[0001] This application relates to the field of cosmetic storage bottles, and more specifically to multi-compartment bottles with high sealing performance. Background Technology

[0002] Freeze-dried essence is a bioactive protein essence that is rapidly freeze-dried into powder form at extremely low temperatures by a water-based solution containing a large number of biological factors. When used, it is activated by compounding with an essence solution.

[0003] To extend the shelf life of freeze-dried essences, freeze-dried powder and essence are stored separately. However, the sealing of the storage bottles in the existing technology is insufficient to meet the storage requirements of freeze-dried powder. External moisture can enter the storage compartment of freeze-dried powder through the structural gaps of the bottle, causing the freeze-dried powder to become damp. Summary of the Invention

[0004] The purpose of this application is to provide a multi-compartment container with high sealing performance, which solves the technical problem that the sealing performance of existing storage containers is insufficient to meet the storage requirements of freeze-dried powder, and that external moisture can enter the compartment where freeze-dried powder is stored through the structural gaps of the container, thus causing the freeze-dried powder to become damp. This application provides a storage container with high sealing performance to prevent freeze-dried powder from becoming damp and to extend the storage time of freeze-dried essence.

[0005] To achieve the above objectives, this application provides a multi-compartment container with high sealing performance, comprising a first container structure and a second container structure.

[0010] In some embodiments, the body further includes a first limiting boss and a second limiting boss, the first limiting boss being disposed on the inner wall of the connecting cylinder and the second limiting boss being disposed on the outer wall of the movable cylinder; when the movable cylinder is in a first extreme position, the first limiting boss and the second limiting boss abut against each other, and there is a certain distance between the piercing part and the puncturable sealing membrane; when the movable cylinder is in a second extreme position, the first limiting boss and the second limiting boss separate, the piercing part pierces the puncturable sealing membrane, and the liquid chamber is connected to the high-barrier chamber.

[0011] In some embodiments, at least one of the first limiting boss and the second limiting boss is annular.

[0012] In some embodiments, the body further includes: a limiting channel disposed on the outer wall of the movable cylinder, the extending direction of the limiting channel being parallel to the axial direction of the movable cylinder; a limiting switch rotatably connected to the connecting cylinder, the limiting switch including a switch handle and a limiting plate, one end of the switch handle extending into the connecting cylinder and having the limiting plate thereon; when the limiting switch is at a first angle, the plane of the limiting plate has an angle with the extending direction of the limiting channel, the limiting plate hinders the piercing part from moving toward the inner cylinder, so that there is a certain distance between the piercing part and the pierceable sealing film; when the limiting switch is at a second angle, the plane of the limiting plate is parallel to the extending direction of the limiting channel, the movable cylinder can move toward the inner cylinder along its own axial direction and pierce the pierceable sealing film through the piercing part.

[0018] In some embodiments, the inner cylinder is made of glass.

[0019] Compared with the prior art, the multi-compartment dispensing bottle with high sealing performance provided in this application has the following advantages:

[0020] 1. The multi-compartment bottle with high sealing performance provided in this application enables the simultaneous storage of lyophilized powder and essence through a multi-compartment structure. To meet the high sealing requirements for storing lyophilized powder, a second sealing ring prevents external moisture from entering the high-barrier compartment containing the lyophilized powder through the structural gap between the outer cylinder and the main body, and through the puncture-resistant sealing membrane. A third sealing ring prevents moisture from the liquid compartment from entering the high-barrier compartment containing the lyophilized powder through the puncture-resistant sealing membrane. Furthermore, a first sealing ring at the gap between the cap and the inner cylinder prevents external moisture from entering the high-barrier compartment containing the lyophilized powder through the structural gap between the outer cylinder and the main body, and through the gap between the cap and the inner cylinder. Through these two sealing structure designs, the high-barrier compartment achieves high sealing performance, preventing the lyophilized powder from becoming damp and extending the storage time of the lyophilized essence.

[0021] 2. The multi-compartment container with high sealing performance provided in this application strengthens the sealing between the outer wall of the cap and the inner wall of the inner cylinder by designing the cap and the inner wall of the inner cylinder to better prevent external moisture from entering the high-barrier compartment storing freeze-dried powder through the structural gap between the outer cylinder and the main body and the gap between the cap and the inner cylinder, thereby improving the sealing performance of the high-barrier compartment.

[0022] 3. The high-sealing multi-compartment container provided in this application improves the sealing performance of the high-barrier compartment by making the inner cylinder of glass. Since glass has high barrier properties and zero moisture and oxygen permeability, it further improves the sealing performance of the high-barrier compartment.

[0023] 4. The high-sealing multi-compartment dispensing bottle provided in this application restricts the movement of the movable cylinder via a limit switch. When the limit switch is opened, the limit plate enters the limit channel, thus no longer obstructing the axial movement of the movable cylinder. The movable cylinder moves towards the punctureable sealing film, eventually puncturing it through the puncture point, allowing the lyophilized powder in the high-barrier compartment to mix with the essence in the liquid compartment. When the limit switch is closed, the limit plate and the limit channel are at a certain angle, preventing the movable cylinder from moving towards the punctureable sealing film, ensuring that the puncture point always maintains a certain distance from the punctureable sealing film.

[0038]

Example 1

[0039] like Figures 1-4 As shown, this embodiment discloses a specific implementation of a multi-compartment dispensing bottle with high sealing performance, including a first dispensing cylinder structure and a second dispensing cylinder structure, wherein, as... Figures 3-4 As shown, the first cylinder structure includes an outer cylinder 1a with a first receiving space, an inner cylinder 1b with a second receiving space, a first sealing ring 1d, and a pressure cap 1h. The outer cylinder 1a has a first opening, through which the first receiving space communicates with the outside of the outer cylinder 1a. The inner cylinder 1b has a second opening, through which the second receiving space communicates with the outside of the inner cylinder 1b, and the inner cylinder 1b is located within the first receiving space. Thus, the outer cylinder 1a protects the inner cylinder 1b from damage caused by external impacts. The pressure cap 1h is connected to the first opening, and the first end of the pressure cap 1h (i.e., Figure 3The right end of the gland 1h is sealed by a puncture-resistant sealing membrane 1f, and the second end of the gland 1h (i.e. Figure 3 The left end of the pressure cap 1h presses the first sealing ring 1d tightly into the second opening. The second accommodating space, the first sealing ring 1d, the pressure cap 1h, and the puncture-resistant sealing film 1f together constitute a high-barrier chamber 1c for storing freeze-dried powder. In this embodiment, the outer cylinder 1a and the inner cylinder 1b are coaxial cylindrical structures, each with an opening at one end. These openings are the first opening of the outer cylinder 1a and the second opening of the inner cylinder 1b, respectively. The puncture-resistant sealing film 1f is made of aluminum foil.

[0040] The second cylinder structure includes a main body and a third sealing ring 2e disposed on the main body. The main body has a liquid chamber 2d for storing liquid. In this embodiment, the liquid chamber 2d is used to store essence. The main body is sleeved on the outer cylinder 1a, and the gap between the outer cylinder 1a and the main body is sealed by the second sealing ring 1g. The third sealing ring 2e presses the puncture-resistant sealing membrane 1f onto the cap 1h. Specifically, in this embodiment, the main body includes a connecting cylinder 2a with openings at both ends. The inner wall of the connecting cylinder 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 puncture-resistant sealing membrane 1f.

[0041] In this embodiment, a multi-compartment structure is used to simultaneously store freeze-dried powder and serum. To meet the high sealing requirements for storing the freeze-dried powder, a second sealing ring 1g prevents external moisture from entering the high-barrier compartment 1c containing the freeze-dried powder through the structural gap between the outer cylinder 1a and the main body, and through the puncture-resistant sealing membrane 1f. A third sealing ring 2e prevents moisture from the liquid compartment 2d from entering the high-barrier compartment 1c containing the freeze-dried powder through the puncture-resistant sealing membrane 1f. Furthermore, through the gap between the cap 1h and the inner cylinder 1b, a first sealing ring 1d prevents external moisture from entering the high-barrier compartment 1c containing the freeze-dried powder through the structural gap between the outer cylinder 1a and the main body, and through the gap between the cap 1h and the inner cylinder 1b. Through these two sealing structure designs, the high-barrier compartment 1c possesses high sealing performance, preventing the freeze-dried powder from becoming damp and extending the storage time of the freeze-dried serum.

[0042] Even better, since glass has zero moisture and oxygen permeability, the inner cylinder 1b is made of 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-compartment dispensing bottle with high sealing performance. Example 2 is based on the example, such as... Figures 3-4As shown, in Embodiment 2, the cap 1h and the inner wall of the inner cylinder 1b are interference-fitted. By designing the cap 1h and the inner wall of the inner cylinder 1b to be interference-fitted, the interference fit 1e between the cap and the inner cylinder is shown in Figure 1e. Figure 3 This strengthens the sealing between the outer wall of the cap 1h and the inner wall of the inner cylinder 1b, better preventing external moisture from entering the high-barrier chamber 1c storing freeze-dried powder through the structural gap between the outer cylinder 1a and the main body, and the gap between the cap 1h and the inner cylinder 1b, thereby improving the sealing performance of the high-barrier chamber 1c.

[0045]

Example 3

[0046] Example 3 discloses another specific implementation of a multi-compartment dispensing bottle with high sealing performance. Example 3 is based on Example 1 or 2, such as... Figures 1-4 As shown, the main body of Embodiment 3 also includes a movable cylinder 2b passing through the third sealing ring 2e. The movable cylinder 2b can move along its own axis. The movable cylinder 2b is provided with a liquid chamber 2d, and the end of the movable cylinder 2b near the punctureable sealing membrane 1f is an open end. The liquid chamber 2d communicates with the outside of the movable cylinder 2b through the end of the movable cylinder 2b near the punctureable sealing membrane 1f.

[0047] like Figures 3-4 As shown, the second barrel structure also includes a piercing part 2f for piercing the pierceable sealing membrane 1f. The piercing part 2f is disposed at the open end of the movable barrel 2b. In this embodiment, the piercing part 2f is a sharp corner formed by two arc surfaces, which can pierce the pierceable sealing membrane 1f.

[0048] When the puncture structure punctures the puncture-resistant sealing membrane 1f, the liquid chamber 2d connects with the high-barrier chamber 1c, thereby mixing the freeze-dried powder and the essence.

[0049] To prevent liquid in the liquid chamber 2d from flowing into the cavity formed between the connecting cylinder 2a and the movable cylinder 2b, the outer wall of the movable cylinder 2b is press-fitted with the third sealing ring 2e, thereby preventing liquid in the liquid chamber 2d from flowing into the cavity formed between the connecting cylinder 2a and the movable cylinder 2b through the gap between the movable cylinder 2b and the third sealing ring 2e.

[0050] More preferably, the main body also includes a first limiting boss 2h and a second limiting boss 2g. The first limiting boss 2h is disposed on the inner wall of the connecting cylinder 2a, and the second limiting boss 2g is disposed on the outer wall of the movable cylinder 2b. In this embodiment, both the first limiting boss 2h and the second limiting boss 2g are arranged in a ring shape. When the movable cylinder 2b is in the first extreme position, the first limiting boss 2h and the second limiting boss 2g abut against each other, and there is a certain distance between the piercing part 2f and the pierceable sealing membrane 1f. At this time, because there is a certain distance between the piercing part 2f and the pierceable sealing membrane 1f, it can be ensured that the pierceable sealing membrane 1f will not break, and the high-barrier chamber 1c and the liquid chamber 2d are in a separated state. When the movable cylinder 2b is in the second extreme position, the first limiting boss 2h and the second limiting boss 2g separate, the piercing part 2f pierces the pierceable sealing membrane 1f, and the liquid chamber 2d and the high-barrier chamber 1c are connected.

[0051] In other embodiments, at least one of the first limiting protrusion 2h and the second limiting protrusion 2g is annular. For example, the first limiting protrusion 2h is annular and the second limiting protrusion 2g is a single block structure or multiple block structures distributed circumferentially; the second limiting protrusion 2g is annular and the first limiting protrusion 2h is a single block structure or multiple block structures distributed circumferentially. Of course, both the first limiting protrusion 2h and the second limiting protrusion 2g can be single block structures or multiple block structures distributed circumferentially, as long as the first limiting protrusion 2h can abut against the second limiting protrusion 2g when the movable cylinder 2b is in the first extreme position. This will not be elaborated further here.

[0052] Better, such as Figure 3 As shown, the main body also includes a limiting channel disposed on the outer wall of the movable cylinder 2b and a limiting switch 2c rotatably connected to the connecting cylinder 2a, specifically, as... Figure 6 As shown, the extension 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 provided 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 cylinder 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. The limit plate 2c1 prevents the piercing part 2f from moving toward the inner cylinder 1b, so that there is a certain distance between the piercing part 2f and the pierceable sealing film 1f. That is, the limit plate 2c1 will abut against one end of the rib 2i, preventing the piercing part 2f from continuing to move toward the inner cylinder 1b, thereby ensuring that the pierceable sealing film 1f is not pierced by the piercing part 2f.

[0055] When the limit switch 2c is in the second angle, the plane where the limit plate 2c1 is located is parallel to the extension direction of the limit channel. The movable cylinder 2b can move towards the inner cylinder 1b along its own axis and puncture the punctureable sealing membrane 1f through the puncture part 2f. That is, the limit plate 2c1 no longer abuts against the rib 2i and is located between the two ribs 2i. At this time, by pushing the movable cylinder 2b towards the direction of the inner cylinder 1b, the puncture part 2f can finally puncture the punctureable sealing membrane 1f, so that the high barrier chamber 1c is connected to the liquid chamber 2d.

[0056] The limit switch 2c restricts the movement of the movable cylinder 2b. It is only opened when it is necessary to connect the high-barrier chamber 1c with the liquid chamber 2d, to prevent premature mixing of the freeze-dried powder in the high-barrier chamber 1c and the liquid in the liquid chamber 2d due to misoperation of the movable cylinder 2b.

[0057]

Example 4

[0058] Example 4 discloses another specific implementation of a multi-compartment dispensing bottle with high sealing performance. Example 4 is based on any one of Examples 1-3, such as... Figures 3-4 As shown, the second material cylinder structure also includes a feed head 3, which is located at the end of the movable cylinder 2b away from the end of the punctureable sealing membrane 1f, and the feed head 3 is connected to the liquid tank 2d.

[0059] At least a portion of the cylinder wall at the position of the movable cylinder 2b corresponding to the liquid chamber 2d can be deformed by inward pressure. Specifically, the thickness of the cylinder wall at the deformable position of the movable cylinder 2b is less than the thickness of the cylinder wall 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 it can deform inward when subjected to inward extrusion force, thereby squeezing the mixed liquid out of the liquid chamber 2d.

[0060] When the freeze-dried essence is needed, first puncture the puncture-resistant sealing film 1f to mix the freeze-dried powder with the essence to form the freeze-dried essence. Then, squeeze the deformable part of the movable cylinder 2b inward to extrude the freeze-dried essence through the feed head 3 into a multi-compartment bottle with high sealing performance.

[0061] More preferably, the multi-compartment container with high sealing performance also includes a cap 4, which is detachably connected to the feed head 3, and a sealing block 4a is provided on the cap 4 at the outlet 3a of the feed head 3. When the cap 4 is connected to the feed head 3, the sealing block 4a blocks the outlet 3a, thereby achieving a seal at the outlet 3a. In this embodiment, the cap 4 is threadedly connected to the feed head 3.

[0062] Of course, in other embodiments, the bottle cap 4 and the feed head 3 can also be connected by snap-fit ​​or other means, which will not be described in detail here.
