Description

Integral high barrier mixing container Technical Field

[0001] The present invention relates to the technical field of mixed material packaging, in particular to an integral high-barrier mixed material container. Background Art

[0002] Currently, it's common to need to mix two materials. To achieve optimal results, the two materials are typically separated beforehand, then mixed just before use. However, if the two materials are stored separately, mixing them becomes more complicated, especially when quantitative quantities are required, which can be time-consuming.

[0003] For example, Chinese utility model patent CN214778047U discloses a push-type mixing bottle, which places a solid substance in a storage part and a liquid substance in the bottle body. When not in use, the solid substance can be stored separately in the same bottle in a quantitative or non-quantitative manner. When in use, the pressing part is pressed to destroy the sealing part, so that the interior of the storage part is connected with the interior of the bottle body. The user holds the push-type mixing bottle and shakes it to mix the solid substance and the liquid substance. The storage is relatively stable in the early stage, and the solid substance can be used immediately after mixing. The whole process is simple and easy to operate, which reduces the operation time.

[0004] For example, Chinese patent CN205661829U discloses a solid-liquid separation mixing bottle. The mixing bottle includes an outer cover, a lower pressure cover, and a container cover. The bottle cover includes a cavity for holding solids. Before taking the medicine, the lower pressure cover is pressed to puncture the bottom of the container cover, allowing the solid in the cavity to mix with the liquid previously placed in the bottle.

[0005] However, since the above-mentioned mixing bottles all achieve material mixing through a pressing structure, the structure is relatively complex, that is, the various components of the mixing bottle are usually made of plastic to reduce the difficulty of assembly and use. In the fields of medicine, chemical industry, tea beverages, etc., the requirements for the barrier properties of packaging containers such as oxygen barrier and water barrier are relatively high, but the barrier properties of plastic mixing bottles are poor, that is, the materials in each chamber of the mixing bottle are easily penetrated by external gases and deteriorated, and even the materials in each chamber may penetrate each other, resulting in poor use effect.

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0029] Figure 1 is a schematic structural diagram of an integral high-barrier mixing container according to a preferred embodiment of the present invention; Figure 2 is a schematic cross-sectional diagram of a first embodiment of the integral high-barrier mixing container shown in Figure 1; Figure 3 is a schematic cross-sectional diagram of a second embodiment of the integral high-barrier mixing container shown in Figure 1; and Figure 4 is a schematic cross-sectional diagram of a third embodiment of the integral high-barrier mixing container shown in Figure 1.

[0030] Example 1

[0031] As shown in Figures 1 and 2, the overall high-barrier mixing container of this embodiment includes a first shell 100, a second shell 200 and a cover 300. The first shell 100 is arranged in the second shell 200. The cover 300 includes a covering portion 310 covering the second shell 200 and a connecting portion 320 formed by axially extending the outer edge of the covering portion 310 and connected to the second shell 200. A barrier layer 1 330 is arranged on the outer wall of the cover 300, a barrier layer 210 is arranged on the outer wall of the second shell 200, and a barrier layer 3 110 is arranged on the outer wall of the first shell 100. The first shell 100 and the second shell 200 are enclosed to form a barrier cavity 1 400 for enclosing and containing materials. The first shell 100 and the cover 300 are enclosed to form a barrier cavity 2 500 for enclosing and containing materials. Specifically, the overall high barrier mixing container of the present invention is that after the first shell 100 is arranged in the second shell 200, the cover 300 is covered with the covering portion 310 on the second shell 200 through the covering portion 310, and then connected to the second shell 200 through the connecting portion 320, so as to seal the second shell 200 while fixing the first shell 100 in the first shell 100. The structure is simple and easy to assemble. Then, the barrier layer 1 330 and the barrier layer 2 210 are respectively arranged on the outer walls of the cover 300 and the second shell 200 to achieve barrier covering of the mixing container to prevent the mixing container from The material is permeated by external gas and deteriorates. By accommodating two different materials in barrier chamber 1 400 and barrier chamber 2 500 respectively, the mixed materials can be used to improve the use effect. At the same time, the barrier layer 3 110 prevents the materials in barrier chamber 1 400 and barrier chamber 2 500 from permeating each other, which would cause the use effect to deteriorate. Compared with the existing technology, this solution has a simple structure and is easy to assemble. It improves the barrier properties of the mixing container at the structural level, so that the materials in the mixing container are placed in a closed chamber with strong barrier properties, and the storage quality of the materials in the mixing container is guaranteed to the greatest extent. It is highly practical and suitable for wide promotion and application. It should be understood that if the mixing container is made of glass, although the barrier properties of the mixing container can be improved, the material cost of the mixing container will increase, and the mixing container will be easily damaged by bumps and difficult to carry. It should be understood that in this embodiment, barrier layer 1 330 is first applied to the outer wall of first housing 100 and barrier layer 210 is applied to the outer wall of cover 300. After first housing 100 and cover 300 are assembled to second housing 200 to form a mixing container, the entire mixing container is plated to form barrier layer 210 on the outer wall of second housing 200. It should be understood that the barrier layers are formed using an ion plating process, the specific steps of which are well known to those skilled in the art and will not be detailed here.

[0032] As shown in Figures 1 and 2, in this embodiment, the second shell 200 includes a connecting ring 220 arranged in the axial direction and connected to the connecting portion 320, and an abutting portion 230 arranged in the radial direction and abutting the connecting portion 320 surface-to-surface. Specifically, the second shell 200 is connected to the connecting portion 320 via the connecting ring 220 to achieve assembly between the second shell 200 and the cover body 300, and then the abutting portion 230 and the connecting portion 320 are abutted surface-to-surface to improve the sealing between the second shell 200 and the cover body 300, preventing external gas from penetrating from between the second shell 200 and the cover body 300 into the various chambers of the mixing container, thereby indirectly improving the barrier properties of the mixing container.

[0033] As shown in Figures 1 and 2, in this embodiment, a sealing portion 340 is integrally injection-molded on the end surface of the connecting portion 320 facing the abutting portion 230, which elastically abuts and seals with the abutting portion 230. Specifically, the sealing portion 340 elastically abuts and seals with the abutting portion 230 to eliminate the gap between the cover 300 and the second shell 200, preventing the infiltration of external air. This, in conjunction with the first barrier layer 330 and the second barrier layer 210, provides comprehensive barrier coverage for the mixing container, maximizing the barrier properties of the mixing container. It should be understood that the provision of the sealing portion 340 increases manufacturing difficulty to a certain extent, and therefore, in other embodiments, the sealing portion 340 may be omitted.

[0034] As shown in Figures 1 and 2, in this embodiment, the inner wall of the connecting portion 320 is provided with a first thread structure, and the outer wall of the connecting ring 220 is provided with a second thread structure that is threadedly connected to the first thread structure. Specifically, the first thread structure and the second thread structure are threadedly connected to each other to securely assemble the cover 300 to the second housing 200.

[0035] As shown in Figures 1 and 2, in this embodiment, the mixing container is arranged in a truncated cone shape, and the bottom end surface area of ​​the second shell 200 is larger than the top end surface area of ​​the cover 300. Specifically, by arranging the mixing container in a truncated cone shape and the bottom end surface area of ​​the second shell 200 being larger than the top end surface area of ​​the cover 300, the mixing container can be placed stably on a horizontal surface, and the openings of the first shell 100 and the second shell 200 are both open, making it easy to access the materials in the mixing container.

[0036] As shown in Figures 1 and 2, in this embodiment, an assembly edge 120 is provided at the opening of the first shell 100, which extends radially outward to between the covering portion 310 and the second shell 200. An injection hole is axially opened on the assembly edge 120, and an injection portion 130 is arranged in the injection hole. A sealing ring 140 that is integrally injection-molded with the injection portion 130 is arranged between the covering portion 310 and the assembly edge 120, and a sealing ring 2 150 that is integrally injection-molded with the injection portion 130 is arranged between the assembly edge 120 and the second shell 200. Specifically, the first shell 100 first forms an assembly edge 120 by extending between the covering portion 310 and the second shell 200 to provide an assembly position through the assembly edge 120, and then opens an injection hole on the assembly edge 120, and then the injection molding portion 130 formed by injection molding in the injection molding hole connects the sealing ring 140 between the covering portion 310 and the assembly edge 120 and the sealing ring 2 150 between the assembly edge 120 and the second shell 200, and then the sealing ring 140 and the sealing ring 2 150 are respectively reliably fixed between the covering portion 310 and the assembly edge 120 and between the assembly edge 120 and the second shell 200, so that the sealing ring 140 and the covering portion 310 are face-to-face sealed, and the sealing ring 2 150 and the second shell 200 are face-to-face sealed, thereby ensuring the sealing between the covering portion 310 and the assembly edge 120 and between the sealing ring 2 150 and the second shell 200. It should be understood that the sealing between the various components of the mixing container often determines the storage quality of the materials. Therefore, the better the sealing, the more reliable the material quality. Optionally, multiple connection holes are provided, and the multiple injection holes are arranged at intervals along the circumference of the assembly edge 120. The injection portions 130 and the injection holes are arranged in a one-to-one correspondence. The multiple injection portions 130 are used to simultaneously connect the sealing ring 140 and the sealing ring 2 150. This maximizes the reliability and compactness of the sealing ring 140 and the sealing ring 2 150 after installation, thereby indirectly improving the sealing between the various components.

[0037] Example 2

[0038] As shown in Figures 1 and 3, this embodiment differs from Example 1 in that: an assembly edge 120 extending radially outward between the cover portion 310 and the second housing 200 is provided at the opening of the first housing 100, and a sealing ring 160 is provided between the second housing 200 and the assembly edge 120, which is integrally injection-molded with the assembly edge 120. Specifically, the first housing 100 is first assembled between the cover portion 310 and the second housing 200, thereby providing an assembly location through the assembly edge 120. Then, a sealing ring 160 is integrally injection-molded between the second housing 200 and the assembly edge 120 using a double-injection molding process on the assembly edge 120. Furthermore, the sealing ring 160 is formed by surface-to-surface contact and sealing with the second housing 200, thereby ensuring the sealing between the first housing 100 and the second housing 200.

[0039] As shown in Figures 1 and 3, in this embodiment, an assembly edge 120 is provided at the opening of the first shell 100, extending radially outward to between the covering portion 310 and the second shell 200. A second sealing ring 170 is provided between the covering portion 310 and the assembly edge 120 and is integrally injection-molded with the assembly edge 120. Specifically, the first shell 100 first provides an assembly location by arranging the assembly edge 120 between the covering portion 310 and the second shell 200 through the assembly edge 120. Then, a second sealing ring 170 is integrally injection-molded between the covering portion 310 and the assembly edge 120 using a double-material injection molding process on the assembly edge 120. Then, the second sealing ring 170 is face-to-face sealed with the covering portion 310, thereby ensuring the sealing between the first shell 100 and the covering portion 310.

[0040] Example 3

[0041] As shown in Figures 1 and 4, this embodiment differs from Example 1 in that: the opening of the first shell 100 is provided with an assembly edge 120 extending radially outward to between the cover portion 310 and the shell, and the edge of the assembly edge 120 extends axially downward to form a wrapping ring 180 that wraps around the opening edge of the second shell 200. Specifically, the first shell 100 first provides an assembly location by disposing the assembly edge 120 between the cover portion 310 and the second shell 200, and then wraps the opening edge of the second shell 200 with the wrapping ring 180, thereby maximizing the surface-to-surface contact area between the shell and the first shell 100, thereby maximizing the sealing between the second shell 200 and the first shell 100.

[0042] As shown in Figures 1 and 4, in this embodiment, the opening of the first shell 100 is provided with an assembly edge 120 extending radially outward to between the cover portion 310 and the second shell 200. The cover portion 310 extends axially downward to form a first ring body 311 and a second ring body 312. The first ring body 311 and the second ring body 312 are arranged at intervals to enclose a plug-in cavity. The assembly edge 120 extends axially upward to form a plug-in ring 190 that plugs into the plug-in cavity. Specifically, the first shell 100 first provides an assembly location by arranging the assembly edge 120 between the cover portion 310 and the second shell 200. Then, the plug-in ring 190 on the assembly edge 120 plugs into the plug-in cavity. The plug-in ring 190 is respectively sealed with the first ring body 311 and the second ring body 312, thereby maximizing the surface-to-surface contact area between the first shell 100 and the cover 300, thereby improving the sealing performance between the first shell 100 and the cover 300.

[0043] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
