Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of powder liquid separation bottle, especially to a bottle cap suitable for storing powder and a powder liquid separation container. BACKGROUND

[0002] Conventional beverages have a short shelf life, which leads to beverages that are not consumed in time expiring very easily. Moreover, with the continuous development of society, people's requirements for the freshness and health of beverages are getting higher and higher, resulting in a lot of expired beverages being discarded, causing great waste. In order to improve the shelf life of beverages, the beverage manufacturing industry usually makes beverage raw materials into a specific dose of powder. This practice can maximize the shelf life of beverages.

[0003] However, it is troublesome to purchase powder and then brew it at home, which does not meet the needs of some people to buy and drink immediately. Therefore, integrated bottle caps that integrate a specific dose of raw material powder with a bottle cap have appeared on the market. The integrated bottle cap is fitted on a bottle containing drinking water. A pre-set piercing member allows the raw material powder in the bottle cap to enter the drinking water at any time and form a beverage, so that it can be used at any time.

[0004] However, there are two main opening methods for existing integrated bottle caps. One is a press type, which drives the piercing member to pierce the inner cap by pressing the outer cap downward. However, the outer cap cannot be reset after it goes down, which will cause the piercing member to be stuck in the piercing area of the inner cap, resulting in slow powder falling speed. The other is a screw type, in which the outer cap and the inner cap are screwed together. The piercing member can be displaced up and down by rotating the outer cap, thereby piercing the inner cap. However, the outer cap rotation and downward pressure is similar to the overall rotation opening of the bottle cap, which is prone to misoperation. SUMMARY

[0005] The utility model takes into account the foregoing problems and is made. The purpose of the utility model is to provide a bottle cap suitable for storing powder and a powder liquid separation container. The bottle cap can drive the piercing member to go down by the deformation amount of the pressing part, thereby realizing piercing of the containing cavity. The operation is simple, and the piercing member can reset with the pressing part after piercing. The discharge port can be completely opened, and the powder falling speed is fast.

[0006] To achieve the above purpose, the utility model provides a bottle cap suitable for storing powder, which comprises:

[0007] An inner cap having a containing cavity for containing powder;

[0008] An outer cap comprising an outer cap edge and an outer cap top. The outer cap edge is sleeved on the outer side of the inner cap. The outer cap top is located at the top of the outer cap edge. A pressing part is provided on the outer cap top.

[0009] A puncturing element is movably disposed between the pressing part and the receiving cavity. The puncturing element has a smooth end and a sharp end. The smooth end can contact the bottom surface of the pressing part, and the sharp end can extend into the receiving cavity and abut against the middle of the bottom surface of the receiving cavity.

[0010] The piercing member has an initial position and a piercing position that pierces the receiving cavity, and the pressing part has a deformation that allows the piercing member to move from the initial position to the piercing position.

[0011] According to the above-described bottle cap suitable for storing powder, the top of the outer cap is entirely provided as a pressing part, and the pressing part is arranged horizontally on the top of the outer cap edge.

[0012] According to the above-described bottle cap suitable for storing powder, the pressing part is located in the middle of the top of the outer cap, and the pressing part is flush with the top of the outer cap.

[0013] According to the above-described bottle cap suitable for storing powder, the pressing part is made of an elastic material, and the smooth end can be connected to the middle of the bottom surface of the pressing part.

[0014] According to the above-described bottle cap suitable for storing powder, the smooth end is fixedly connected to the pressing part.

[0015] According to the above-described bottle cap suitable for storing powder, the bottom surface of the receiving cavity is provided with multiple grooves, the multiple grooves intersect and are uniformly radial from the center, and the sharp part faces the intersection of the multiple grooves.

[0016] A powder-liquid separation container, comprising:

[0017] Bottle body;

[0018] As described above, a bottle cap suitable for storing powder is located directly above the bottle body, and the inner cap can be threaded into the opening of the bottle body.

[0019] According to the powder-liquid separation container described above, the bottom of the outer cover edge is provided with a tear-off ring, which can be fixedly connected to the bottle body through the tear-off ring.

[0020] According to the powder-liquid separation container described above, the top of the inner cover is provided with an upwardly protruding first limiting part, and a plurality of first limiting parts are arranged circumferentially at intervals on the top of the inner cover. The bottom of the top of the outer cover is provided with a downwardly protruding second limiting part, and a plurality of second limiting parts are arranged circumferentially at intervals on the bottom of the top of the outer cover. The second limiting part can be inserted between two adjacent first limiting parts. When the outer cover rotates, the second limiting part can abut against the first limiting part.

[0021] According to the powder-liquid separation container described above, the outer cover edge is provided with a plurality of planar gripping parts, and the plurality of gripping parts are arranged in a ring on the outer cover edge.

[0022] This utility model has the following beneficial effects:

[0032] 2. Bottle body. Detailed Implementation

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] like Figures 1-4As shown, a bottle cap suitable for storing powder includes an inner cap 11, an outer cap 12, and a piercing element 13. In this embodiment, the inner cap 11 can be threadedly connected to the opening of the bottle body 2, the outer cap 12 can be fastened to the inner cap 11, and can drive the inner cap 11 to rotate, thereby opening the opening of the bottle body 2. The piercing element 13 is located between the inner cap 11 and the outer cap 12 and is used to pierce the inner cap 11, so that the powder inside the inner cap 11 can fall into the bottle body 2.

[0035] Specifically, the inner cover 11 has a receiving cavity 111 for containing powder. The outer cover 12 includes an outer cover edge 122 and an outer cover top 121. The outer cover edge 122 is fitted onto the outside of the inner cover 11, and the outer cover top 121 is located on top of the outer cover edge 122 and directly above the inner cover 11. A pressing part 121a is provided on the outer cover top 121. A piercing member 13 is movably disposed between the pressing part 121a and the receiving cavity 111. The piercing member 13 has a smooth end 131 and a sharp end 132. The smooth end 131 can contact the bottom surface of the pressing part 121a, and the sharp end 132 can extend into the receiving cavity 111 and can interact with the receiving cavity 111. When the bottom surface abuts against the center, pressing the pressing part 121a can drive the piercing member 13 downward. The sharp part of the piercing member 13 can pierce the receiving cavity 111, allowing the powder in the receiving cavity 111 to fall. In this embodiment, the smooth end 131 is fixedly connected to the bottom surface of the pressing part 121a. During the pressing process of the pressing part 121a, it will move downward with the pressing part 121a, driving the sharp part to pierce the receiving cavity 111. When the pressing part 121a resets, the pressing part 121a drives the smooth end 131 to reset together, thereby driving the sharp part to disengage from the pierced opening on the receiving cavity 111, which can make the powder discharge faster.

[0036] Specifically, the piercing member 13 has an initial position and a piercing position that pierces the receiving cavity 111. The pressing part 121a has a deformation that allows the piercing member 13 to move from the initial position to the piercing position. That is, the deformation of the pressing part 121a should be greater than the distance from the initial position to the piercing position of the piercing member 13 in order to achieve effective driving of the piercing member 13.

[0037] In this embodiment, the pressing part 121a is located in the middle of the top of the outer cover 121, and the pressing part 121a is flush with the top of the outer cover 121. The overall flushness ensures that the top of the outer cover 121 is horizontal, making it less likely to be accidentally touched during daily transportation and handling, reducing the risk of accidental touch, and improving the aesthetic performance of the appearance.

[0038] Of course, in another embodiment, the top 121 of the outer cover can be set as a pressing part 121a, and the pressing part 121a is arranged horizontally on the top of the edge 122 of the outer cover. Similarly, when the pressing part 121a is driven, the piercing part 13 can be driven to move together, and the piercing part 13 can also be driven.

[0039] In this embodiment, in order to make the pressing part 121a deformable, the pressing part 121a is made of an elastic material. The smooth end 131 can be connected to the middle of the bottom surface of the pressing part 121a. It is worth noting that although the pressing part 121a is made of an elastic material in this embodiment, it is not suitable to use a material with excessive elasticity. This would cause the pressing part 121a to fail to drive the puncturing part 13 well and also make it easy to accidentally hit it. Therefore, it is necessary to select a material with a certain elasticity and a large elastic modulus. A large force needs to be applied to ensure that it deforms, which can both ensure the driving of the puncturing part 13 and prevent simple accidental contact from causing the powder to dissolve into the liquid.

[0040] Materials with moderate elasticity include some composite materials and engineering plastics.

[0041] Composite materials include fiber-reinforced composite materials, such as glass fiber reinforced plastic (GFRP) or carbon fiber reinforced plastic (CFRP). Their elastic modulus can be adjusted according to the ratio of matrix material and reinforcing fiber, and can be adjusted according to actual elastic modulus requirements to meet the requirements.

[0042] Some engineering plastics, such as polyamide (nylon) and polycarbonate (PC), can also provide good rigidity and exhibit good performance in specific applications.

[0043] Of course, when selecting the material for the pressing part 121a, we should not only consider its elastic properties, but also its performance in terms of cost, usage environment, chemical stability, recyclability, environmental protection and industry standards. In particular, in terms of industry standards, since it needs to come into contact with food materials, if it does not meet industry standards, it may cause very serious food safety problems.

[0044] Of course, in addition to the pressing part 121a being made of an elastic material as mentioned in this embodiment, the outer cover top 121 of the outer periphery of the pressing part 121a may also be made of an elastic material, while the pressing part 121a itself is made of a hard material. When the pressing part 121a is driven, the pressing part 121a can also be displaced, thereby causing the puncturing member 13 to be displaced. This should not exceed the scope of this application.

[0045] To facilitate the piercing member 13 piercing the receiving cavity 111, multiple grooves 111a are provided on the bottom surface of the receiving cavity 111. These grooves 111a intersect and are arranged in a uniform radial pattern, with the sharp points facing the intersection of the grooves 111a. In this embodiment, the grooves 111a are actually easy-open slots. The grooves 111a reduce the strength of the bottom surface of the receiving cavity 111, and the intersection is the weakest point. When the sharp points apply force to this point, the receiving cavity 111 can be easily broken, and the area where the multiple grooves 111a are distributed can also crack.

[0046] In this context, a notch 111a typically refers to a small, linear damage or mark formed on the surface of an object by cutting, scratching, or other means. The specific definition of a notch 111a may vary slightly depending on the application.

[0047] In engineering and manufacturing: Scratches 111a may refer to fine scratches on the surface of tools or machine parts caused by wear or improper handling, which can sometimes affect the function and lifespan of the parts;

[0048] In gemology: Scratches 111a may refer to minor damage on the surface of a diamond or other gemstone;

[0049] In archaeology: Inscription 111a may refer to artificial marks on ancient artifacts, used for decoration, recording, or other cultural purposes;

[0050] In materials science: researchers may intentionally create notches 111a on the surface of a material to study its fracture behavior or wear resistance.

[0051] In pharmaceutics, "111a" is a professional term used in pharmaceutics, meaning a directional crack. Usually, a "111a" on a tablet means that the tablet has a "111a" mark that allows it to be precisely cracked.

[0052] Of course, in either case, a notch 111a usually means a breach of surface integrity and may affect the overall performance or appearance of an object.

[0053] The notch 111a in this embodiment is mainly defined in pharmaceutics. Its main purpose is to negatively affect the overall strength of the cavity 111, reduce the overall strength of the cavity 111, make it easy to crack, and achieve the purpose of guiding the cracking.

[0054] A powder-liquid separation container, comprising:

[0055] Bottle 2, which is used to hold the liquid for mixing with the powder;

[0056] As described above, a bottle cap 1 suitable for storing powder is located directly above the bottle body 2, and the bottle cap 1 can be fixedly connected to the bottle body 2 to seal the bottle body 2, preventing the liquid inside the bottle body 2 from flowing out. Moreover, by releasing the powder inside the bottle cap 1, the powder can fall into the liquid in the bottle body 2 and be mixed. This design can achieve separation of powder and liquid, thereby improving the shelf life of the beverage.

[0057] The inner cap 11 is threadedly connected to the opening of the bottle body 2. That is, the inner cap 11 has an internal thread on its inner side and an external thread that matches it at the opening of the bottle body 2. The internal thread and the external thread are engaged and connected.

[0058] In order to enable the outer cap 12 to drive the inner cap 11 to open the bottle mouth 2, the top of the inner cap 11 is provided with an upwardly protruding first limiting part 112, and multiple first limiting parts 112 are arranged circumferentially at intervals on the top of the inner cap 11. The bottom of the outer cap top 121 is provided with a downwardly protruding second limiting part 121b, and multiple second limiting parts 121b are arranged circumferentially at intervals on the bottom of the outer cap top 121. When the outer cap edge 122 is fitted on the outside of the inner cap 11, multiple second limiting parts 121b can be inserted between two adjacent first limiting parts 112. When the outer cap 12 is rotated, the second limiting part 121b will abut against the first limiting part 112, thereby driving the inner cap 11 to rotate together and detach it from the bottle body 2.

[0059] In order to lock the outer cap 12, a tear ring 122a is provided at the bottom of the outer cap edge 122, and the outer cap edge 122 can be fixedly connected to the bottle body 2 through the tear ring 122a. Before the tear ring 122a is torn off, the outer cap 12 cannot move up and down or rotate as a whole, thus preventing the opening of the bottle body 2 from being opened. It also prevents the puncture part 13 from puncturing the receiving cavity 111 due to the outer cap 12 being accidentally pressed down. Only after the tear ring 122a is torn off can the outer cap 12 be unlocked, and the inner cap 11 can be driven.

[0060] In order to facilitate gripping of the outer cover 12, a plurality of planar gripping parts 122b are provided on the side of the outer cover edge 122. The plurality of gripping parts 122b are arranged in a ring on the side of the outer cover edge 122. When the operator grips the outer cover edge 122, the gripping parts 122b can increase the friction between the fingers and the outer cover edge 122, making it easier to drive it to rotate.
