[0033] like Figure 1 and Figure 2 The utility model provides an instant-open bottle cap with built-in concentrated powder and liquid, comprising an outer cap 1 which can be screwed and fixed on a bottle mouth, an inner cap 2 and a limiting member 3.

[0034] The outer cover 1 forms a first accommodating space 1A therein, and the inner cover 2 can be plugged into the first accommodating space 1A of the outer cover 1 .

[0035] like Figure 6 The bottom end of the inner cover 2 is encapsulated with aluminum foil (not shown in the figure), and the aluminum foil and the inner cover 2 form a second accommodating space 2A. The second accommodating space 2A is filled with concentrated powder liquid. When not in use, the aluminum foil is sealed. The concentrated powder liquid can be various beverages or granules, etc., without limitation.

[0036] In particular, Figure 4 and Figure 5 A piercing portion 1G capable of piercing the aluminum foil is provided at the inner bottom of the outer cover 1, and the piercing portion 1G forms a through structure in the first accommodating space 1A. Figure 1 As shown, the inner cover 2 is pressed downward along its axial direction and the pierced portion 1G is punctured to form a first state, and the concentrated powder liquid in the second accommodating space 2A falls into the bottle through the first accommodating space 1A, thereby mixing the concentrated powder liquid and the solvent (such as mineral water), achieving instant drinking, and strictly ensuring the most original taste.

[0037] The limiting member 3 can be matched and buckled on the outside of the inner cover 2, and overlapped on the outer cover 1 so that the inner cover 2 is in the second state. In the second state, the second accommodating space 2A is completely closed, that is, when not in use, the limiting member 3 holds the inner cover 2 at a height, and the aluminum foil and the piercing portion 1G will not touch each other, and the aluminum foil is suspended in the air. When it is necessary to remove the limiting member 3, an axial force is applied to the inner cover 2 to press it down in the first state. At this time, the piercing portion 1G pierces the aluminum foil, and the concentrated powder liquid in the second accommodating space 2A can fall into the bottle. It can be found that it can be opened by simply pressing the inner cover 2, and the operation is convenient.

[0038] In the present embodiment, specifically, the outer cover 1 includes an integrally formed first outer cover body 1B and a second outer cover body 1C, the second outer cover body 1C is convexly formed downward, the first accommodating space 1A is located inside the second outer cover body 1C, the second outer cover body 1C is a cylindrical structure, and according to the different sizes of bottle mouths, the first outer cover body 1B and the second outer cover body 1C also have corresponding different models to meet the use of a variety of bottles.

[0039] As mentioned above, more specifically, the inner wall of the first outer cover body 1B is provided with a thread, and a gap is left between the inner wall of the first outer cover body 1B and the second outer cover body 1C, the outer cover 1 is fixed to the bottle mouth by screwing on the thread of the inner wall of the first outer cover body 1B, and the second outer cover body 1C is placed in the bottle mouth. The installation is very simple. For example, after opening the bottle cap of mineral water, the instant bottle cap can be directly installed on the bottle mouth. At this time, the second outer cover body 1C will be inside the bottle, and the outer wall of the first outer cover body 1B is arranged with axially extending anti-slip grooves 1D along the circumferential direction. The design of the anti-slip grooves 1D is convenient for tightening or screwing to the bottle mouth, thereby enhancing the friction with the hand.

[0040] In this embodiment, a convex ring 1E is formed at the inner lower part of the outer cover 1, and the piercing portion 1G is formed and connected inside the convex ring 1E.

[0041] Specifically, the piercing portion 1G includes a cross-shaped tooth plate 1H, the end of which is molded and connected to the inner wall of the convex ring 1E. The tooth plate 1H is high in the middle and gradually decreases towards both ends, and a plurality of teeth are arranged on the upper end of the tooth plate 1H. The tooth plate 1H is located at the center of the tooth plate 1H and is in a sharp shape, which can pierce the aluminum foil to put the inner cover 2 in the first state. A first blanking trough 1F is formed between the tooth plate 1H and the convex ring 1E. After taking out the limiter 3, the inner cover 2 is photographed. After the center of the tooth plate 1H pierces the aluminum foil first, the tooth plate 1H then stretches the aluminum foil to expand the opening, and the concentrated powder liquid continues to fall.

[0042] In addition, a second feeding trough 1I is provided between the outer side of the convex ring 1E and the inner wall of the outer cover 1. The second feeding trough 1I is arranged along the center of the outer cover 1 in an annular direction. The bottle can also be shaken to allow the concentrated powder liquid to fall into the solvent from the first feeding trough 1F and the second feeding trough 1I.

[0043] In this embodiment, the inner wall of the second outer cover body 1C of the outer cover 1 is further formed with a first rib 1J and a first groove 1K. The first rib 1J is located at the upper part of the first groove 1K. Both the first rib 1J and the first groove 1K are arc-shaped surfaces and are arranged closely up and down.

[0044] Furthermore, Figure 6 The outer part of the inner cover 2 is sequentially formed with a second groove 2B, a second convex rib 2C, a third convex rib 2D and a third groove 2E from top to bottom. A fourth convex rib 2F is also provided above the second groove 2B. The second groove 2B, the second convex rib 2C, the third convex rib 2D, the third groove 2E and the fourth convex rib 2F are all arc-shaped surfaces. When the inner cover 2 is in the second state, the third groove 2E and the first convex rib 1J are snap-fitted. At this time, the inner cover 2 is positioned and fixed on the outer cover 1, so that the inner cover 2 will not move in the axial direction and can only rotate, thereby ensuring that the aluminum foil will not be punctured by the piercing portion 1G.

[0045] When the inner cover 2 is in the first state, the first convex rib 1J and the second groove 2B, the first groove 1K and the second convex rib 2C are engaged with each other, and the top of the inner cover 2 is an umbrella-shaped surface, which makes it feel more comfortable when in contact with the hand.

[0046] In the present utility model, a further implementation scheme is that the inner wall of the limiter 3 forms a fourth groove 3A. In the second state, the limiter 3 is buckled on the outside of the inner cover 2, and the fourth rib 2F is engaged with the fourth groove 3A. The limiter 3 overlaps the upper edge of the first outer cover body 1B, so that when not in use, the limiter 3 can prevent the aluminum foil from being punctured by the piercing portion 1G. The cooperation of the third groove 2E and the first rib 1J makes the inner cover 2 fixed on the outer cover 1 and will not fall off, which is convenient for transportation and storage. It can be seen that when the instant opening bottle cap is in use, the limiter 3 is first removed, and then the inner cover 2 is pressed down, and then it is shaken to make the concentrated powder liquid fall into the solvent or water for mixing, which can be simply opened and ensure that each opening can be completed smoothly.

[0047] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
