[0033] In order to make the technical means, creative features, objectives and effects of the invention easier to understand, the invention is further described below with reference to specific diagrams. However, the invention is not limited to the following implementation cases.

[0034] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings in this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them. They are not used to limit the conditions under which the present invention can be implemented. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in the present invention without affecting the efficacy and purpose that can be achieved by the present invention.

[0035] like Figure 1 、 Figure 2 、 Figure 6 As shown, this embodiment discloses a two-component mixing device, including an outer container 1, an inner container 2, and a stirring spoon. The inner container 2 is arranged in the outer container 1, and the container mouths of the outer container 1 and the inner container 2 are threadedly connected. The cavity between the inner container 2 and the outer container 1 constitutes a first cavity 11, and the first cavity 11 is used to store a liquid first material. The inner container 2 has a second cavity 21 inside, and the second cavity 21 is used to store a solid or liquid second material.

[0036] like Figure 5 、 Figure 6 、 Figure 7 As shown, a puncture member 12 is provided in the first cavity 11, and the puncture member 12 is connected to the inner wall of the outer container 1. A puncturable membrane 22 is provided at the bottom of the inner container 2. A thin-walled area that is easily punctured can be provided at the bottom of the inner container 2, and the puncturable membrane 22 is formed by the thin-walled area. Alternatively, an opening can be provided at the bottom of the inner container 2, and the opening can be covered and sealed by an aluminum film or other sealing film, and the puncturable membrane 22 is formed by the sealing film. A sheath 23 is provided in the second cavity 21, and the sheath 23 extends upward from the bottom of the inner container 2. The first end of the sheath 23 is connected to the puncturable membrane 22, and the second end of the sheath 23 is sealed. A discharge hole 231 is provided on the peripheral wall of the upper part of the sheath 23. When the inner container 2 and the outer container 1 are rotated relative to each other for the first time in a predetermined direction, the piercing member 12 moves upward to pierce the puncturable membrane 22 and is accommodated in the sheath 23, so that the first cavity 11 and the second cavity 21 are connected, and the stirring spoon is inserted into the second cavity 21 to stir the material and take the mixed material.

[0037] like Figure 3 、 Figure 6As shown, the container mouth of the outer container 1 is provided with a folded first folded edge 13, and the container mouth of the inner container 2 is provided with a folded second folded edge 24. The first folded edge 13 and the second folded edge 24 can be folded inward or outward. Preferably, the first folded edge 13 and the second folded edge 24 are both folded outward, and the second folded edge 24 is folded to the outside of the first folded edge 13. A first alignment structure 131 is provided at the skirt of the first folded edge 13, and a second alignment structure 241 is provided at the skirt of the second folded edge 24. The first alignment structure 131 is a first boss, and the second alignment structure 241 is a second groove matching the first boss. The first alignment structure 131 and the second alignment structure 241 constitute a limiting portion, and the lower end of the second groove has an opening, and the first boss can enter the second groove from the aforementioned opening. The first alignment structure 131 and the second alignment structure 241 are used to control the relative position between the inner container 2 and the outer container 1 during assembly. On the one hand, they control the alignment angle during assembly so that the threads between the inner container 2 and the outer container 1 are kept in their initial position. On the other hand, they control the insertion height of the inner container 2 within the outer container 1 during assembly to prevent the piercing member 12 from puncturing the pierceable membrane 22 when inserted too deeply, causing device failure. Specifically, when assembled to the predetermined position, the threads between the outer container 1 and the inner container 2 interfere with each other to control the assembly height. Simultaneously, the first alignment structure 131, i.e., the first boss, enters the second alignment structure 241, i.e., the second groove. The first boss abuts against the top of the second groove to further control the assembly height.

[0038] like Figure 3 、 Figure 6 、 Figure 7 As shown, the skirt portion of the first fold 13 forms a safety ring 14, with a first alignment structure 131 provided on the safety ring 14. The safety ring 14 is removably connected to the main portion of the first fold 13 via a frangible portion 15. The frangible portion 15 is weaker than the retaining portion and is a thin ring or a plurality of break bridges. The thickness of the thin ring is less than that of the safety ring 14 and the main portion of the first fold 13. The safety ring 14 is opaque, while the second fold 24 is transparent, making it easy to observe whether the frangible portion 15 is broken and the position or status of the safety ring 14, thereby determining whether the device is being opened for the first time.

[0039] The outer wall of the safety ring 14 is provided with an outwardly protruding buckle rib 141, and the skirt of the second folded edge 24 is provided with an inwardly protruding buckle platform 242. The buckle rib 141 can be engaged with the buckle platform 242. The buckle rib 141 and the buckle platform 242 are used to prevent the safety ring 14 from falling after the breakable portion 15 is broken.

[0040] like Figure 6 As shown, a first interference edge 25 is provided on the outer peripheral wall of the container opening of the inner container 2. The first interference edge 25 can interfere with the inner peripheral wall of the container opening of the outer container 1 to form a seal to seal the first cavity 11.

[0041] like Figure 1 、 Figure 2 As shown, the container opening of the inner container 2 is covered with a removable sealing member 3, which is used to seal the second cavity 21. The sealing member 3 can be an aluminum film, a screw cap or a snap cap.

[0042] like Figure 6 、 Figure 7 As shown, the technical solution described in the above embodiment is used as follows:

[0043] During assembly, the inner container 2 is pressed into the outer container 1. Due to the action of the limiting parts at the container openings of the inner container 2 and the outer container 1, the inner container 2 and the outer container 1 can only be assembled at a predetermined angle and height. On the one hand, it ensures that the threads between the inner container 2 and the outer container 1 can be controlled at the initial position; on the other hand, it is used to control the insertion height of the inner container 2 in the outer container 1 to prevent the first interference edge 25 from interfering with the peripheral wall of the container opening of the outer container 1 to form a seal when the insertion is too shallow, and at the same time prevent the piercing member 12 from piercing the pierceable membrane 22 when the insertion is too deep, causing the device to fail.

[0044] During use, the container mouth of the inner container 2 is rotated to rotate the inner container 2 relative to the outer container 1, and the limiting portion provided at the container mouth of the outer container 1 and the inner container 2 limits the rotation between the inner container 2 and the outer container 1, wherein the first alignment structure 131 in the limiting portion is provided on the skirt of the first folded edge 13 of the outer container 1, namely the safety ring 14. When the inner container 2 and the outer container 1 are rotated relative to each other for the first time, under the action of external force, the fragile portion 15 at the connection between the safety ring 14 and the first folded edge 13 breaks due to its low strength, the safety ring 14 detaches from the outer container 1, and the limiting portion fails. However, due to the action of the buckle rib 141 and the buckle platform 242, the safety ring 14 is still connected to the second folded edge 24 of the inner container 2 and will not fall into the environment.

[0045] Since the second folded edge 24 is transparent, the user can observe whether the breakable portion 15 is broken and whether the safety ring 14 falls off, thereby determining whether the device has been opened for the first time.

[0046] It should be noted that the above describes in detail the preferred embodiments of the present invention. It should be understood that numerous modifications and variations based on the concepts of the present invention can be made by those skilled in the art without inventive effort. Therefore, any technical solution that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
