Description

Mixing container with high inner barrier Technical Field

[0001] The present invention relates to the technical field of material packaging containers, in particular to a mixing container with a high-barrier inner cavity. 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, that is, the material of their internal shells is usually made of plastic or other materials that are easily broken by pressing. 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. However, the barrier properties of the internal cavity formed by the plastic shell are relatively low and can no longer meet the use requirements of the above-mentioned fields.

[0013] Furthermore, a connecting edge is provided at the opening of the inner plug, extending radially outward to between the cover body and the shell body, and the edge of the connecting edge extends axially downward to form a wrapping ring that wraps the opening edge of the shell body.

[0014] Furthermore, the opening of the inner plug is provided with a connecting edge extending radially outward to between the cover body and the shell body, the cover body is extended axially downward to form a first ring portion and a second ring portion, the first ring portion and the second ring portion are arranged at intervals to enclose to form a plug-in cavity, and the connecting edge extends axially upward to form a plug-in ring that is plugged into the plug-in cavity.

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 inner cavity high-barrier mixing container according to a preferred embodiment of the present invention; Figure 2 is a schematic structural diagram of a first embodiment of the inner cavity high-barrier mixing container shown in Figure 1; Figure 3 is a schematic structural diagram of a second embodiment of the inner cavity high-barrier mixing container shown in Figure 1; and Figure 4 is a schematic structural diagram of a fourth embodiment of the inner cavity high-barrier mixing container shown in Figure 1.

[0030] Example 1

[0031] As shown in Figures 1 and 2, the inner cavity high-barrier mixing container of this embodiment includes a shell 100, an inner plug 200 and a sealing cover 300. The sealing cover 300 includes a cover body 310 and a connecting ring 320 formed by axially extending the outer edge of the cover body 310 and connected to the shell 100. The cover body 310 covers the shell 100 and encloses the shell 100 to form a closed accommodating cavity 400 for accommodating materials. A barrier layer 1 330 is arranged on the inner wall surface of the cover body 310, and a barrier layer 290 is arranged on the inner wall surface of the inner plug 200. The inner plug 200 is inserted into the shell 100 and the inner wall surface of the inner plug 200 and the inner wall surface of the cover body 310 enclose a closed barrier cavity 500 for accommodating materials. Specifically, the inner cavity high barrier mixing container of the present invention, after the sealing cover 300 is covered on the shell 100 through the cover body 310, is connected to the shell 100 through the connecting ring 320, the shell 100 and the cover body 310 enclose a accommodating cavity 400 to hold the first material, and the inner plug 200 and the cover body 310 enclose a barrier cavity 500 to hold the second material, so that the two materials can be enclosed at the same time through the accommodating cavity 400 and the barrier cavity 500, and a barrier is arranged on the inner wall surface of the cover body 310. Layer 1 330 and barrier layer 2 290 are arranged on the inner wall surface of the inner plug 200 to improve the barrier properties of the barrier cavity 500 through barrier layer 1 330 and barrier layer 2 290. Compared with the existing technology, this solution not only achieves the simultaneous encapsulation of two materials so that they can be mixed and used to improve the use effect, but also improves the barrier properties of the barrier cavity 500 from the structural level. This makes the material of the inner plug 200 and the cover 310 unrestricted, facilitates mass production, is highly practical, and is suitable for widespread promotion and application. It should be understood that although the cavity structure made of glass material has higher barrier properties than the cavity structure made of plastic material, the material cost is higher and it is easy to damage. It should be understood that the barrier film is formed by ion plating process. The specific steps of the ion plating process are well known to those skilled in the art and will not be described in detail here.

[0032] As shown in Figures 1 and 2, in this embodiment, a connecting edge 210 extending radially outward to between the cover body 310 and the shell 100 is provided at the opening of the inner plug 200, a connecting hole is axially opened on the connecting edge 210, a connecting portion 220 is arranged in the connecting hole, a sealing ring 1 230 integrally injection-molded with the connecting portion 220 is arranged between the cover body 310 and the connecting edge 210, and a sealing ring 240 integrally injection-molded with the connecting portion 220 is arranged between the connecting edge 210 and the shell 100. Specifically, the inner plug 200 first arranges a connecting edge 210 between the cover 310 and the housing 100 to provide an assembly location through the connecting edge 210, then opens a connecting hole in the connecting edge 210, and then connects the sealing ring 1 230 between the cover 310 and the connecting edge 210 and the sealing ring 240 between the connecting edge 210 and the housing 100 through the connecting portion 220 in the connecting hole, thereby reliably fixing the sealing ring 1 230 and the sealing ring 240 between the cover 310 and the connecting edge 210 and between the connecting edge 210 and the housing 100, respectively, so that the sealing ring 1 230 and the sealing ring 240 are in full contact and sealed with each other, and the sealing ring 240 and the housing 100 are in full contact and sealed with each other, thereby ensuring the sealing between the connecting edge 210 and the cover 310 and between the connecting edge 210 and the housing 100. 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 quality of the materials. Optionally, a plurality of connecting holes are provided, and the plurality of connecting holes are arranged at intervals along the circumference of the connecting edge 210, and the connecting parts 220 and the connecting holes are arranged in a one-to-one correspondence, so that the sealing ring 1 230 and the sealing ring 2 240 can be connected simultaneously through the plurality of connecting parts 220, so as to maximize the reliability and compactness of the sealing ring 1 230 and the sealing ring 2 240 after installation, thereby indirectly improving the sealing between the components.

[0033] As shown in Figures 1 and 2, in this embodiment, an oxygen-absorbing layer is provided within the barrier cavity 500. Specifically, the oxygen-absorbing layer absorbs oxygen within the barrier cavity 500, thereby preventing external oxygen from penetrating and preventing oxidation reactions within the material within the barrier cavity 500, thereby ensuring the storage quality of the material within the barrier cavity 500. Optionally, the oxygen-absorbing layer is made of an oxygen-absorbing material. It should be understood that oxygen-absorbing materials are commonly known to those skilled in the art and will not be described in detail here.

[0034] As shown in Figures 1 and 2, in this embodiment, a force application groove 110 is radially inwardly recessed on the outer peripheral wall of the housing 100. Specifically, the force application groove 110 forms a force application point for applying force, so as to facilitate applying force to open the sealing cover 300.

[0035] As shown in Figures 1 and 2, in this embodiment, the inner wall of the connecting ring 320 is provided with an internal thread structure 321, and the outer wall of the housing 100 is provided with an external thread structure 120 that is threadedly connected to the internal thread structure 321. Specifically, the internal thread structure 321 and the external thread structure 120 are threadedly connected to each other to securely assemble the sealing cover 300 to the housing 100, and the threaded structure facilitates disassembly and re-use.

[0036] As shown in Figures 1 and 2, in this embodiment, a stabilizing groove 130 is axially inwardly recessed at the bottom of the housing 100. Specifically, the stabilizing groove 130 makes the radial cross-section of the bottom of the housing 100 approximately triangular, thereby improving the stability of the mixing container after placement.

[0037] Example 2

[0038] As shown in Figures 1 and 3, the difference between this embodiment and Example 1 is that: a connecting edge 210 extending radially outward between the cover body 310 and the housing 100 is provided at the opening of the inner plug 200, and a sealing ring 250 is provided between the housing 100 and the connecting edge 210, which is integrally injection-molded with the connecting edge 210. Specifically, the inner plug 200 first arranges the connecting edge 210 between the cover body 310 and the housing 100 to provide an assembly location through the connecting edge 210, and then uses a double-material injection molding process to integrally injection-mold a sealing ring 250 between the housing 100 and the connecting edge 210 on the connecting edge 210. The sealing ring 250 is then face-to-face sealed with the housing 100, thereby ensuring the sealing between the inner plug 200 and the housing 100.

[0039] As shown in Figures 1 and 3, in this embodiment, a connecting edge 210 extending radially outward to between the cover body 310 and the housing 100 is provided at the opening of the inner plug 200, and a second sealing ring 260 is provided between the cover body 310 and the connecting edge 210, which is integrally injection-molded with the connecting edge 210. Specifically, the inner plug 200 first arranges the connecting edge 210 between the cover body 310 and the housing 100 to provide an assembly position through the connecting edge 210, and then uses a double-material injection molding process on the connecting edge 210 to integrally injection-mold the second sealing ring 260 between the cover body 310 and the connecting edge 210. Then, the second sealing ring 260 is face-to-face sealed with the cover body 310, thereby ensuring the sealing between the inner plug 200 and the cover body 310.

[0040] Example 3

[0041] As shown in Figures 1 and 4, the difference between this embodiment and Example 1 is that a connecting edge 210 extending radially outward to between the cover body 310 and the housing 100 is provided at the opening of the inner plug 200, and the edge of the connecting edge 210 extends axially downward to form a wrapping ring 270 that wraps around the opening edge of the housing 100. Specifically, the inner plug 200 first arranges the connecting edge 210 between the cover body 310 and the housing 100 to provide an assembly position through the connecting edge 210, and then wraps the opening edge of the housing 100 with the wrapping ring 270, thereby maximizing the surface-to-surface contact area between the housing 100 and the inner plug 200, thereby maximizing the sealing between the housing 100 and the inner plug 200.

[0042] As shown in Figures 1 and 4, in this embodiment, the opening of the inner plug 200 is provided with a connecting edge 210 extending radially outward to between the cover body 310 and the housing 100. The cover body 310 extends axially downward to form a first ring portion 311 and a second ring portion 312. The first ring portion 311 and the second ring portion 312 are arranged at intervals to enclose an insertion cavity. The connecting edge 210 extends axially upward to form an inserting ring 280 that plugs into the inserting cavity. Specifically, the inner plug 200 first arranges the connecting edge 210 between the cover body 310 and the housing 100 to provide an assembly position through the connecting edge 210. Then, the inserting ring 280 on the connecting edge 210 plugs into the inserting cavity. The inserting ring 280 is respectively in surface contact with the first ring portion 311 and the second ring portion 312, thereby maximizing the surface contact area between the inner plug 200 and the sealing cover 300, thereby improving the sealing performance between the inner plug 200 and the sealing 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.
