Description

Technical Field

[0001] The present invention belongs to the field of packaging technology, and in particular relates to a packaging container for separate storage. The packaging container is suitable for storing various substances, such as medicines, cosmetics, chemical preparations, etc., and is particularly suitable for storing cosmetics, wherein the cosmetics can be liquid, solid, powder or other skin care substances. Background Art

[0002] In the field of packaging technology, two materials often need to be mixed for use. However, sometimes the mixture is unstable, so when not in use, the two materials need to be sealed and stored separately; when they need to be used, the two materials are mixed to achieve the purpose of ready-to-use. The materials may include medicines, chemicals, skin care products or cosmetics, etc. Traditionally, when two materials are packaged separately in a bottle and need to be mixed, the user needs to open the seals of the two bottles separately, and then pour the material in one bottle into the other bottle for mixing. The mixing operation steps are cumbersome, which increases the burden on users. With the development of skin care technology, some solid skin care products need to be sealed and stored (such as freeze-dried powder). They cannot come into contact with air before mixing with other substances, otherwise they will lose their due effect. When used, they are mixed with other liquid skin care products. During the mixing process, it is also necessary to ensure that the freeze-dried powder cannot come into contact with air. This is particularly important.

[0003] To this end, a Chinese utility model patent with patent number ZL202222319060.2 (publication number CN218537457U) "A packaging container and a mixed packaging bottle adapted for the packaging container" discloses such a packaging container structure specifically for such skin care products, including a containing part, a connecting member and a push rod, the containing part has a first containing cavity for containing a first medium, and the opening of the first containing cavity is provided with a pierceable sealing barrier. The push rod is movably arranged at the end of the connecting member to pierce the sealing barrier. The connecting member is operably sleeved on the containing part and pushed toward the containing part, so that the sealing barrier is pierced by the push rod, and the containing part then drives the push rod to move in a direction away from the containing part, so as to realize the conduction of the first containing cavity. By providing a packaging container and an extrusion part provided on the packaging container, and forming two closed containing cavities respectively, the user only needs to push the containing part toward the push rod, and drive the push rod to move to make the first containing cavity and the second containing cavity conduct to realize the mixing of the two materials, thereby improving the convenience of material mixing.

[0004] However, the aforementioned patent has the following defects:

[0005] 1. The push rod has both puncture and plug functions, so the material used for the push rod is relatively soft, resulting in a low hardness of the puncture part on the push rod, which is not easy to puncture the sealing film; the puncture part has a cutting edge located on one side, and there is only one puncture hole when the sealing film is punctured, which makes it difficult for the liquid medium in the packaging container equipped with the push rod to flow out.

[0006] 2. Because the push rod has both puncture and plug functions, when the accommodating part is screwed into the packaging container, the push rod may be pushed away first and then the sealing film may be punctured. Some users may turn the packaging container upside down (i.e., the mouth of the packaging container faces downward) during operation, then the content of the packaging container will flow out first, and the sealing film is not punctured. The outflowing medium cannot immediately enter the first accommodating chamber to mix with the substance inside, but instead flows outside the accommodating part, causing waste.

[0007] 3. The main body of the containing part is made of glass, and it is not convenient to directly set a sealing film. Therefore, a port bracket is threadedly connected to the extension of the main body, and a sealing ring is provided at the opening of the port bracket and the containing part. The mouth of the port bracket is sealed with a sealing film. When in use, solid or powdered substances are placed in the containing part, and the vacuum requirement is relatively high. Therefore, before mixing with the solution substance in the packaging container, the packaging needs to be well sealed (to prevent the substance in the containing part from contacting the air). However, when using it, consumers may accidentally open the port bracket, causing the substance inside to become ineffective.

[0008] In summary, the packaging container disclosed in the aforementioned patent document can be further improved. Summary of the invention

[0009] The technical problem to be solved by the present invention is to provide a structurally improved separated storage packaging container in view of the above-mentioned existing technical status, which ensures that the packaging container is punctured before opening when in use, so as to better and conveniently achieve mixing of two materials.

[0010] The technical solution adopted by the present invention to solve the above technical problem is: a packaging container for separation and preservation, comprising a first container with a first accommodating cavity, wherein a sealing film that can be pierced is provided at the opening of the first container;

[0011] a second container having a second receiving cavity;

[0012] A docking sleeve, fixed at the mouth of the second container, having an interface portion for connecting the first container and a connecting channel for connecting the interface portion and the second accommodating cavity;

[0013] It is characterized by: it also includes

[0014] The puncture portion is fixed on the docking sleeve and is located inside the interface portion;

[0015] A piston is movably disposed in the connecting channel to block or open the connecting channel;

[0016] The interface portion is operably mounted on the first container. The first container moves toward the puncturing portion and the piston, so that the sealing film is punctured by the puncturing portion. The first container also pushes the piston to move away from the first container to open the connecting channel, thereby achieving conduction between the first accommodating chamber and the second accommodating chamber.

[0017] Preferably, the first container has a base portion and an extension portion, the extension portion is sleeved with a port bracket, the sealing film is arranged at the mouth of the port bracket, and a first sealing ring is arranged at the opening connection between the port bracket and the first container; the first container can be made of glass, and the port bracket can be made of plastic material, which is convenient for setting a sealing film at the mouth of the port bracket. The outer peripheral wall of the extension portion is provided with a first external thread, and the inner peripheral wall of the port bracket is provided with a first internal thread matching the first external thread; the threaded connection method is conducive to connecting the port bracket to the extension portion of the first container, and the locking force of the threaded connection is large, ensuring that the first sealing ring is effectively pressed at the opening connection between the port bracket and the first container, and the sealing effect is good. The outer peripheral wall of the port bracket is provided with a second external thread, and the inner peripheral wall of the interface portion is provided with a second internal thread matching the second external thread. Similarly, the threaded connection method is conducive to firmly connecting the port bracket to the interface portion of the docking sleeve.

[0018] Further improvement, the upper part of the inner circumferential wall of the above-mentioned port bracket is provided with a stop-retraction elastic foot with an elastic tendency toward the central axis direction of the port bracket, and the outer circumferential wall of the extension part is provided with a raised clamping rib. When the port bracket is screwed on the extension part, the stop-retraction elastic foot is pressed against the upper part of the clamping rib, and the end face of the extension part presses the first sealing ring.

[0019] The elastic foot for preventing retreat presses against the clamping rib to prevent the port bracket from retreating. After the port bracket is tightened on the extension part, the user cannot open the mouth of the first container even if the port bracket is reversed, ensuring that the medium in the first container is always isolated by the sealing film, preventing consumers from accidentally opening the port bracket, causing the medium inside to contact with the air and become ineffective. The clamping rib can be an arc-shaped convex rib independent of the first external thread. The arc-shaped convex rib can be annular, or arc-shaped convex rib segments spaced along the circumference, or it can be the first external thread of the innermost circle.

[0020] As a further improvement, an annular inner shoulder is provided on the upper part of the inner wall of the above-mentioned interface part, and a plurality of first stop blocks arranged along the circumferential interval are provided on the top surface of the annular inner shoulder, and the surface of the first stop block corresponding to the direction in which the port bracket is screwed into the interface part is a first inclined surface, and the surface of the first stop block corresponding to the direction in which the port bracket is screwed out of the interface part is a first stop plane; an annular shoulder is provided at the upper end of the port bracket, and a plurality of second stop blocks arranged along the circumferential interval are provided on the bottom surface of the annular shoulder, and the surface of the second stop block corresponding to the direction in which the port bracket is screwed into the interface part is a second inclined surface, and the surface of the second stop block corresponding to the direction in which the port bracket is screwed out of the interface part is a second stop plane; when the port bracket is screwed tight in the interface part, the first stop blocks and the second stop blocks are arranged alternately.

[0021] When the port bracket is rotated in reverse, the first stop plane and the second stop plane conflict with each other to prevent it from reversing. That is, the first stop block and the second stop block prevent the port bracket from rotating in reverse (reverse rotation can cause the port bracket to detach from the interface part). This means that when the port bracket is screwed into the interface part, the port bracket can no longer detach from the interface part and always remains in the tightened position to prevent the user from accidentally detaching the first container from the docking sleeve along with the port bracket, causing the mixed liquid to flow out.

[0022] As a further improvement, a second sealing ring is provided on the bottom surface of the interface part, and the second sealing ring is located below the second internal thread. When the sealing film on the port bracket is punctured by the puncture part, the port bracket abuts against the second sealing ring. When the sealing film on the port bracket is punctured by the puncture part, the second sealing ring forms a seal with the port bracket and the interface part, and the sealing position is located below the second internal thread, so as to better prevent the solution flowing out of the second accommodating chamber from flowing out between the first internal thread and the second external thread, and ensure that the solution flowing out of the second accommodating chamber flows into the first accommodating chamber.

[0023] As a further improvement, the puncture portion is integrally formed with the docking sleeve, which is more convenient for manufacturing. Of course, in theory, the puncture portion can also be fixed in other ways. There are two puncture portions, which are arranged in the upper end wall of the connecting channel and extend upward into the interface portion. The two puncture portions can puncture the sealing film at the beginning to form two inlets, which are more conducive to forming convection and facilitating the solution to flow into the first accommodating chamber.

[0024] As a preferred structure of the piston, the piston includes an integrally formed sealing portion and a push rod portion, and the push rod portion has at least two sealing portions, and the sealing portion is arranged at the lower end of the push rod portion. When the push rod portion is not triggered by the first container, the sealing portion is tightly matched with the lower end of the connecting channel to seal the second accommodating chamber, and the upper end of the push rod portion extends into the interface portion; the first container abuts against the push rod portion during the movement to drive the sealing portion to move away from the first container. The piston consists of two major parts, the sealing portion and the push rod portion, each of which performs its own function. The sealing portion plays the role of sealing the connecting channel, and the push rod portion plays the role of transmitting the thrust of the first container to the sealing portion. The piston with at least two push rod portions is more stable when being pushed by the first container as a whole. If the push is not stable, the sealing portion is tilted by force, and the resistance is large and it is not easy to push the sealing portion downward.

[0025] As an improvement, each of the push rod parts is connected together by a connecting ring formed integrally therewith, and when the push rod part is not triggered by the first container, the connecting ring and the inner wall of the upper port of the connecting channel are closely matched with each other by an inclined surface. The connecting ring connects the push rod parts together, increases the strength of the push rod parts, and prevents the push rod parts from bending and deforming due to force. At the same time, the connecting ring and the inner wall inclined surface of the upper port of the connecting channel are closely matched, which better ensures that the sealing part can be better in a sealing position under normal conditions.

[0026] As a further improvement, the upper inner wall of the second accommodating chamber is formed with a blocking rib, and when the sealing part moves down to open the connecting channel, the blocking rib blocks the sealing part. The blocking rib blocks the sealing part to prevent the piston from falling into the lower part of the second accommodating chamber as a whole.

[0027] Furthermore, when the sealing part is in a state of being tightly matched with the lower end of the connecting channel, the top end of the piercing part is higher than the top end of the push rod part, so that when the first container moves toward the piercing part and the piston, the sealing film is first pierced, and then the piston is pushed away from the first container to open the connecting channel, which can better ensure that the medium in the second container does not overflow from the junction of the first container and the docking sleeve to the outside of the first container.

[0028] Preferably, the second container is made of an elastic material and can be squeezed. The second container is provided with an extrusion port, and a soft plug is provided at the extrusion port for sealing. The lower end of the docking sleeve is inserted into and fastened to the mouth of the second container. The second container can be squeezed, similar to an elastic dropper. When in use, only the soft plug needs to be opened and the second container needs to be squeezed. The mixed solution in the second containing chamber can be dripped out for human use, and the user can quantitatively mix the solution based on their own needs.

[0029] Furthermore, it also includes a decorative sleeve and a protective sleeve. The decorative sleeve has a stepped through hole. The upper end of the second container is also stepped. The upper end of the second container is placed in the stepped through hole of the decorative sleeve and fixed by bonding. The lower end of the decorative sleeve has a connecting portion. The protective sleeve is pluggable and snap-fitted outside the connecting portion. The second container exposed at the lower part of the decorative sleeve is placed in the protective sleeve. The decorative sleeve covers the upper end of the second container. The decorative sleeve can be made of other materials to increase the strength and protect the head of the second container. The decorative sleeve can also be made of various colors or patterns, which is conducive to making the product into different series. The protective sleeve plays a role in protecting the lower part of the second container to prevent external force from squeezing the second container when it is not needed. The protective sleeve can be made of transparent plastic material.

[0030] Compared with the prior art, the advantages of the present invention are:

[0031] 1. Two independent and closed accommodating chambers can better preserve the two materials separately, ensure sealing, and prevent the two materials from contacting the outside world and causing changes in their properties.

[0032] 2. When the materials in the two accommodating chambers need to be mixed, it is only necessary to insert the first container into the interface portion of the docking sleeve, and move the first container toward the puncturing portion and the piston so that the sealing film is punctured by the puncturing portion. The first container also pushes the piston to move away from the first container to open the connecting channel, thereby realizing the conduction between the first accommodating chamber and the second accommodating chamber. The materials are then mixed, and the material mixing operation is convenient.

[0033] 3. Importantly, the present solution sets the puncture part and the piston independently. The puncture part can be made of harder plastic, which is sharper and easier to puncture the sealing film; the piston can be made of softer plastic, which is easier to seal. In addition, the puncture part is fixed in the docking sleeve (preferably, the puncture part and the docking sleeve are integrally formed). Since the puncture part is fixed relative to the second container, it is ensured that the puncture part punctures the sealing film. The further movement of the first container drives the piston to move and open the connecting channel, thereby realizing the conduction between the first and second accommodating chambers. This structure better ensures that the puncture is performed before the conduction, thereby preventing the solution in the second accommodating chamber from overflowing.

[0042] The present invention is further described in detail below with reference to the accompanying drawings.

[0043] like Figures 1 to 8 Shown is a preferred embodiment of the present invention.

[0044] A packaging container for separate storage, comprising

[0045] The first container 1 has a first accommodating cavity 3 a. In an actual use scenario, freeze-dried balls or freeze-dried powder are placed in the first accommodating cavity 3 a , and a puncturable sealing film 4 is provided at the opening of the first container 1 .

[0046] The second container 2 has a second accommodating chamber 3b. In an actual use scenario, a skin care liquid for dissolving freeze-dried balls or freeze-dried powder is placed in the second accommodating chamber 3b.

[0047] The docking sleeve 5 is fixed at the mouth of the second container 1, and has an interface portion 51 for connecting the first container 1, and a connecting channel 52 for connecting the interface portion 51 and the second accommodating chamber 3b;

[0048] The piercing portion 6 is fixed on the docking sleeve 5 and is located in the interface portion 51 . In this embodiment, the piercing portion 6 is integrally formed with the docking sleeve 5 . There are two piercing portions 6 and they are arranged in the upper end wall of the connecting channel 52 and extend upward into the interface portion 51 .

[0049] The piston 7 is movably disposed in the connecting passage 52 to block or open the connecting passage 52;

[0050] The interface portion 51 is operably mounted on the first container 1. The first container 1 moves toward the puncturing portion 6 and the piston 7, so that the sealing film 4 is punctured by the puncturing portion 6. The first container 1 also pushes the piston 7 to move away from the first container 1 to open the connecting channel 52, thereby realizing the conduction between the first accommodating chamber 3a and the second accommodating chamber 3b.

[0051] The first container 1 comprises a base portion 11 and an extension portion 12, a port bracket 8 is sleeved and connected to the extension portion 12, a sealing film 4 is arranged at the mouth end of the port bracket 8, and a first sealing ring 10a is arranged at the opening connection between the port bracket 8 and the first container 1; a first external thread 121 is arranged on the outer peripheral wall of the extension portion 12, and a first internal thread 81 matching the first external thread 121 is arranged on the inner peripheral wall of the port bracket 8; a second external thread 82 is arranged on the outer peripheral wall of the port bracket 8, and a sealing cap is connected to the outer thread of the port bracket 8 before use. A second internal thread 511 matching the second external thread 82 is arranged on the inner peripheral wall of the interface portion 51, and a sealing cap is connected to the inner thread of the interface portion 51 before use.

[0052] The upper part of the inner peripheral wall of the port bracket 8 is provided with a stop elastic foot 83 with an elastic tendency toward the central axis direction of the port bracket 8, and the outer peripheral wall of the extension part 12 is provided with a protruding clamping rib 122. When the port bracket 8 is screwed on the extension part 12, the stop elastic foot 83 presses against the upper part of the clamping rib 122, and the end face of the extension part 12 presses the first sealing ring 10a. The stop elastic foot 83 presses against the upper part of the clamping rib 122 to stop the port bracket 8. After the port bracket 8 is screwed on the extension part 12, the user cannot open the mouth of the first container 1 even if the port bracket 8 is reversed, ensuring that the medium in the first container 1 is always in a state of being isolated by the sealing film 4, preventing consumers from opening the port bracket 8 by mistake, causing the medium inside to contact the air and fail.

[0053] An annular inner shoulder 512 is provided on the upper part of the inner wall of the interface part 51, and a plurality of first stop blocks 9a arranged at intervals along the circumference are provided on the top surface of the annular inner shoulder 512, and the surface of the first stop block 9a corresponding to the direction in which the port bracket 8 is screwed into the interface part 51 is a first inclined surface 9a1, and the surface of the first stop block 9a corresponding to the direction in which the port bracket 8 is screwed out of the interface part 51 is a first stop plane 9a2; an annular shoulder 84 is provided on the upper end of the port bracket 8, and a plurality of second stop blocks 9b arranged at intervals along the circumference are provided on the bottom surface of the annular shoulder 84, and the surface of the second stop block 9b corresponding to the direction in which the port bracket 8 is screwed into the interface part 51 is a second inclined surface 9b1, and the surface of the second stop block 9b corresponding to the direction in which the port bracket 8 is screwed out of the interface part is a second stop plane 9b2; when the port bracket 8 is screwed tightly in the interface part 51, the first stop blocks 9a and the second stop blocks 9b are arranged alternately.

[0054] When the port bracket 8 is rotated in reverse, the first stop plane 9a2 and the second stop plane 9b2 conflict with each other to prevent it from reversing. That is, the first stop block 9a and the second stop block 9b prevent the port bracket 8 from rotating in reverse (reverse rotation can cause the port bracket 8 to disengage from the interface portion 51). This means that when the port bracket 8 is screwed into the interface portion 51, the port bracket 8 can no longer disengage from the interface portion 51 and always remains in the screwed position to prevent the user from accidentally disengaging the first container 1 from the docking sleeve 5 together with the port bracket 8, causing the mixed liquid to flow out.

[0055] A second sealing ring 10 b is provided on the bottom surface of the interface portion 51 . The second sealing ring 10 b is located below the second internal thread 511 . When the sealing film 4 on the port bracket 8 is punctured by the puncturing portion 6 , the port bracket 8 abuts against the second sealing ring 10 b .

[0056] The piston 7 includes a sealing portion 71 and a push rod portion 72 which are integrally formed. In the present embodiment, there are two push rod portions 72 which are radially symmetrically arranged. The sealing portion 71 is arranged at the lower end of the push rod portion 72. When the push rod portion 72 is not triggered by the first container 1, the sealing portion 71 is tightly matched with the lower end of the connecting channel 52 to seal the second accommodating chamber 3b, and the upper end of the push rod portion 72 extends into the interface portion 51; the first container 1 abuts against the push rod portion 72 during movement to drive the sealing portion 71 to move away from the first container 1.

[0057] Each of the push rod portions 72 is connected together by a connecting ring 73 formed integrally therewith. When the push rod portion 72 is not triggered by the first container 1, the connecting ring 73 and the inner wall of the upper end of the connecting channel 52 are closely fitted with an inclined surface.

[0058] A blocking rib 3b1 is formed on the upper inner wall of the second accommodating cavity 3b. When the sealing portion 71 moves down to open the connecting channel 52, the blocking rib 3b1 blocks the sealing portion 71. When the sealing portion 71 is in a state of being tightly matched with the lower end of the connecting channel 52, the top end of the piercing portion 6 is higher than the top end of the push rod portion 72.

[0059] In this embodiment, the second container 2 is made of elastic material and can be squeezed, that is, the second container can be flattened by fingers and can rebound to its original shape. The second container 2 is provided with an extrusion port 21, and a soft plug 22 is provided at the extrusion port 21 for sealing. The lower end of the docking sleeve 5 is inserted into and fastened to the mouth of the second container 2; it also includes a decorative sleeve 13 and a protective sleeve 14. The decorative sleeve 13 has a stepped through hole. The upper end of the second container 2 is also stepped in shape. The upper end of the second container 2 is placed in the stepped through hole of the decorative sleeve 13 and is adhesively fixed. The lower end of the decorative sleeve 13 has a connecting portion 131, and the protective sleeve 14 is snap-fitted onto the outside of the connecting portion 131 in a pluggable manner, so that the second container 2 at the lower part of the decorative sleeve 13 is exposed and placed in the protective sleeve 14.

[0060] The working principle and process of this separated storage packaging container are as follows:

[0061] When mixed, Figures 1 to 4 As shown, the port bracket 8 of the first container 1 is first screwed into the interface portion 51 of the docking sleeve 5, and the first container 1 is rotated and moved downward together with the port bracket 8 until the sealing film 4 is punctured by the puncture portion 6, and the port bracket 8 abuts against the second sealing ring 10b and is further screwed into the first container 1. The first container 1 continues to move downward, and the first container 1 abuts against the push rod portion 72 during the movement to drive the sealing portion 71 to move away from the first container 1, opening the connecting channel 52, and realizing the conduction between the first accommodating chamber 3a and the second accommodating chamber 3b. The solution in the second accommodating chamber 3b is successively added to the first accommodating chamber 3a through the connecting channel 52 and the rupture of the sealing film 4, and mixed with the substance therein.

[0062] In this solution, the puncture part 6 and the piston 7 are independently arranged. The puncture part 6 can be made of harder plastic, which is sharper and is conducive to puncturing the sealing film 4; the piston 7 can be made of softer plastic, which is conducive to sealing. In addition, the puncture part 6 is fixed in the docking sleeve 5 (preferably, the puncture part 6 and the docking sleeve 5 are integrally formed). Since the position of the puncture part 6 is fixed relative to the second container 2, it is ensured that the puncture part 6 punctures the sealing film 4. The further movement of the first container 1 drives the piston 7 to move and open the connecting channel 52, so as to realize the conduction between the first accommodating chamber 3a and the second accommodating chamber 3b. This structure better ensures that the puncture is performed before the conduction, and the solution in the second accommodating chamber 3b is prevented from overflowing.

[0063] It should be noted that in the description of this embodiment, the terms "front, back", "left, right", "inside, outside", "upper, lower" and the like indicating directions or positional relationships are all based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. The terms "install", "connect", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
