Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a cover and moisture-proof packaging. Background Technology

[0002] In some pharmaceuticals or foods, when mixed with solvents to form a liquid or viscous final product, their stability and efficacy tend to gradually decrease with increasing storage time. Extending shelf life by adding preservatives or other additives may pose certain health risks. While storing solid and liquid components separately can extend the shelf life of such pharmaceuticals or foods to some extent, it is relatively inconvenient to carry and use.

[0003] Furthermore, especially for instant medicines or foods, the products are very susceptible to deterioration or failure due to insufficient moisture-proof or sealing properties of the packaging, which can affect subsequent use. Utility Model Content

[0004] The purpose of this invention is to provide a cover and moisture-proof packaging that combines the separate storage of solid and liquid substances into one unit, thereby extending shelf life and facilitating carrying and use. Furthermore, the addition of a moisture-proof design for solid substance storage prevents product deterioration or failure, improving packaging reliability.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A cover includes a cover body, a flip cover, and a vent plate. The cover body is provided with a partition that divides it into an upper half and a lower half. The flip cover is rotatably attached to the cover body and has a moisture-proof cavity for filling a desiccant. The vent plate is disposed at the opening of the moisture-proof cavity and is used to encapsulate the desiccant. The upper half of the cover body is used to seal with the closed flip cover to form a first storage cavity, and the lower half of the cover body is used to fit over the opening of a target container.

[0007] In the above solution, the internal space of the casing is divided by a partition, with the upper part forming an independent storage chamber for the first substance when combined with a flip-top, providing excellent moisture protection to prevent deterioration or failure. The lower part has the ability to quickly connect with another container, allowing two different substances to be stored separately yet combined, thereby extending shelf life and making it more convenient to carry and use.

[0008] In some embodiments, the flip cover includes an attachment ring and a cover body, the attachment ring being snapped onto the top of the sleeve; one side of the cover body is flipped to connect to the attachment ring, and the other side is provided with an operating port.

[0009] In the above scheme, the attachment ring and the sleeve body can be assembled together through the concave-convex structure. One side of the cover body can be connected to the attachment ring through the connecting part, and the cover body can be flipped by about 180° relative to the attachment ring, so as to facilitate the taking and placing of the first substance. By providing an operation port on the other side of the cover body, the user can conveniently exert force to open the cover.

[0010] In some embodiments, the lower end of the moisture-proof cavity side wall is provided with a radially inwardly rolled first rolled edge part in continuous circumferential direction, which is used to wrap the edge of the air permeable plate.

[0011] In some embodiments, the moisture-proof cavity side wall is provided with micro-holes communicating between the inside and the outside.

[0012] In the above scheme, by providing micro-holes on the moisture-proof cavity side wall, the ventilation area can be increased, thereby improving the moisture-proof capability of the first storage cavity.

[0013] In some embodiments, the flip cover is further provided with a sealing ring, which surrounds the outer periphery of the moisture-proof cavity, and the sealing ring is provided with a protruding part, which is used to interfere with the opening of the target container for sealing.

[0014] In the above scheme, the sealing ring is used to fit the inner wall of the opening of the target container, thereby improving the sealing between the flip cover and the target container, ensuring the airtightness of the first storage cavity and improving the storage environment. The protruding part can interfere with the opening of the target container for sealing, thereby further improving the sealing between the sealing ring and the target container.

[0015] In some embodiments, the lower end of the sealing ring is provided with a radially inwardly rolled second rolled edge part in non-continuous circumferential direction.

[0016] In the above scheme, the second rolled edge part has the effect of elastic support. When the sealing ring contacts the opening of the target container, the second rolled edge part can abut against the moisture-proof cavity and give the sealing ring a reverse force, so that the sealing ring tightly fits the opening of the target container, thereby ensuring the reliability of the sealing. On the other hand, the second rolled edge part is also used to limit the gap between the sealing ring and the moisture-proof cavity, so as to prevent the first substance (such as test paper, tablets) from being stuck in the gap, thereby causing damage to the first substance or affecting the sealing performance of the sealing ring.

[0017] In some embodiments, the distance from the second rolled edge part to the moisture-proof cavity side wall is less than or equal to 1 mm, and the distance between adjacent first rolled edge parts is less than or equal to 1 mm.

[0018] In the above scheme, this range design can limit the first substance from entering the gap between the sealing ring and the moisture-proof cavity, while ensuring that the gas exchange path between the inside and the outside of the moisture-proof cavity is not affected.

[0019] In some embodiments, the lower half of the sleeve body is provided with a plurality of vertical ribs, which are used to interfere with the opening of the target container for fixing.

[0020] In the above scheme, the vertical rib of the lower half of the sleeve body can interfere with the opening of the target container to be fixed, so that the sleeve cover can be quickly connected with another container, and has the advantages of convenient disassembly and assembly.

[0021] In some embodiments, the outer periphery of the sleeve body is provided with anti-skid lines.

[0022] In the above scheme, the anti-skid lines can be located at the bottom region of the sleeve body, for increasing the friction with the hands, and facilitating the insertion and extraction operation of the sleeve body.

[0023] A moisture-proof package comprises a bottle body and the sleeve cover described above; the bottle body is provided with a second storage cavity, and the lower half of the sleeve body is sleeved at the opening of the bottle body.

[0024] In the above scheme, the sleeve cover can be integrated with the bottle body, and can store the first and second substances respectively, so as to prolong the shelf life, and is more convenient to carry and use.

[0025] In some embodiments, the opening of the bottle body is provided with a sealing layer.

[0026] In the above scheme, the sealing layer can be an aluminum foil sealing layer, a PE sealing layer, a PP sealing layer, etc., so as to improve the sealing property of the second substance storage, and prevent deterioration or failure.

[0027] Compared with the prior art, the beneficial effects of the utility model at least include:

[0028] 1. The upper half of the sleeve body cooperates with the flip cover to form an independent first storage cavity, and has good moisture-proof function, so as to prevent the storage from deteriorating or failing.

[0029] 2. The lower half of the sleeve body has the ability of quick docking with another container, so that two different substances can be stored separately but integrated, so as to prolong the shelf life, and is more convenient to carry and use. BRIEF DESCRIPTION OF DRAWINGS

[0035] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations can be implemented in any number of manners, and are not limited to the embodiments described herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the inventive concept of example implementations to those skilled in the art. Like reference numerals refer to like or similar structures throughout the drawings, and repeated description of them will be omitted.

[0036] The words expressing position and direction described in the present application are explained by taking the drawings as an example, but changes can also be made as needed, and the changes made are included in the protection scope of the present application.

[0037] Referring to Figure 1 and Figure 2 , the present application discloses a cover, comprising a cover body 1, a flip cover 2 and an air-permeable plate 3.

[0038] Among them, the cover body 1 is provided with a partition 11, which can be integrally formed at the middle position to divide the internal space of the cover body 1 into two parts of upper half and lower half. In the present application, the upper half of the cover body 1 is used to seal with the closed flip cover 2 and form a first storage cavity 5, and the first storage cavity 5 is used to store a first substance, such as powder, tablet, etc. The lower half of the cover body 1 is used to sleeve the opening of a target container, such as a bottle body 6, so that the cover can be quickly connected with another container and has the ability of independent storage.

[0039] The flip cover 2 is reversibly attached to the cover body 1, and by controlling the opening and closing of the flip cover 2, the first substance in the first storage cavity 5 can be taken out or placed. As an example, the flip cover 2 comprises an attachment ring 21 and a cover body 22, wherein the attachment ring 21 is clamped on the top of the cover body 1, and the two can be assembled together through concave-convex structure. One side of the cover body 22 is connected with the attachment ring 21, for example, a connecting portion 23 (see Figure 3 ) can be used as an intermediate bridge to realize the flip connection, and the other side of the cover body 22 is also provided with an operation port 227, so as to facilitate the user to force the cover to open. In a preferred embodiment, the cover body 22 can be flipped about 180° relative to the attachment ring 21, so as to facilitate the taking and placing of the first substance.

[0040] In addition, the flip cover 2 is provided with a moisture-proof cavity 221, which is filled with a desiccant 4 and is sealed by a gas-permeable plate 3 arranged at the cavity opening of the moisture-proof cavity 221, so as to achieve the moisture-proof function. As an example, the moisture-proof cavity 221 can be integrally formed on the cover body 22, and the lower end of the sidewall of the moisture-proof cavity 221 is provided with a first edge-rolling part 222 which is radially inwardly rolled and continuously rolled in the circumferential direction, so as to seal the edge of the gas-permeable plate 3 and achieve the sealing function. In this embodiment, the gas-permeable plate 3 is preferably a paper plate, which has the advantages of low cost and good gas permeability, and the desiccant 4 can be a non-toxic and high-adsorption granular desiccant such as a molecular sieve desiccant or a silica gel desiccant.

[0041] The present application separates the space inside the sleeve body 1 by the partition 11, so that the upper half cooperates with the flip cover 2 to form a first storage cavity 5 for storing the first substance and has good moisture-proof function to prevent deterioration or failure. The lower half has the ability to quickly dock with another container, so that two different substances can be stored separately but integrated, thereby prolonging the shelf life and being more convenient to carry and use.

[0042] Still as Figure 2 shown, in some embodiments, the sidewall of the moisture-proof cavity 221 is provided with micro-holes 226 which are in communication between the inside and the outside, so as to increase the ventilation area and improve the moisture-proof ability of the first storage cavity 5.

[0043] In some embodiments, the flip cover 2 is further provided with a sealing ring 223 which surrounds the outer periphery of the moisture-proof cavity 221, so as to be fitted with the inner wall of the opening of the target container, thereby improving the sealing between the flip cover 2 and the target container, improving the sealing of the first storage cavity 5 and improving the storage environment.

[0044] Preferably, the sealing ring 223 is provided with a protruding part 224 which is used for interference sealing with the opening of the target container, so as to further improve the sealing between the sealing ring 223 and the target container.

[0045] Further, the lower end of the sealing ring 223 is provided with a second edge-rolling part 225 which is radially inwardly rolled and discontinuously rolled in the circumferential direction. In this embodiment, the second edge-rolling part 225 has the function of elastic support, and when the sealing ring 223 contacts the opening of the target container, the second edge-rolling part 225 can abut against the moisture-proof cavity 221 and give the sealing ring 223 a reverse force, so that the sealing ring 223 is tightly attached to the opening of the target container, thereby ensuring the reliability of the sealing. On the other hand, the second edge-rolling part 225 is also used to limit the gap between the sealing ring 223 and the moisture-proof cavity 221, so as to prevent the first substance (such as test paper or tablets) from being stuck in the gap and causing damage to the first substance or affecting the sealing performance of the sealing ring 223.

[0046] Further, the distance from the second crimping part 225 to the side wall of the moisture-proof cavity 221 is less than or equal to 1 mm, and the distance between adjacent second crimping parts 225 is less than or equal to 1 mm, so as to limit the first substance from entering the gap between the sealing ring 223 and the moisture-proof cavity 221, while ensuring that the gas exchange path inside and outside the moisture-proof cavity 221 is not affected.

[0047] In some embodiments, the lower half of the sleeve 1 is provided with a plurality of vertical ribs 12, which are circumferentially distributed on the inner wall of the sleeve 1 and can interfere with the opening of the target container for fixation. For example, the vertical ribs 12 can interfere with the sealing cover (see Figure 4 ) on the target container for fixation, achieving quick connection with another container while limiting circumferential rotation, improving stability after connection, and having the advantage of convenient disassembly and assembly.

[0048] In some embodiments, the outer periphery of the sleeve 1 is provided with anti-slip patterns 13, which can be located at the bottom region of the sleeve 1, for increasing the friction with the hand and facilitating the insertion and extraction operation of the sleeve 1.

[0049] The utility model discloses still a kind of moisture-proof package, including bottle body 6 and above-mentioned sleeve cover.

[0050] Wherein, bottle body 6 is provided with second storage cavity 61, second storage cavity 61 is used to store second substance, for example solvent, and can be sealed by the sealing cover arranged at the opening of bottle body 6.And the lower half of sleeve 1 is sleeved at the opening of bottle body 6, so that sleeve cover is integrated with bottle body 6, but first substance and second substance can be stored respectively, so as to prolong shelf life, and it is more convenient to carry and use.
