Description

Technical Field

[0001] The utility model relates to the technical field of fresh-keeping, in particular to a bow-shaped cover with built-in fresh-keeping material. Background Art

[0002] Existing open containers such as cans and bottles often contain foods, medicines, etc. Once most of the original packaging on the market is opened, the air inside and outside is exchanged. Even if the container is sealed again, new air will still enter the container, resulting in a shortened shelf life of the stored food and medicine.

[0003] Small packages of deoxidizers, desiccants and other preservatives are often used on the market for preservation. However, on the one hand, they are easily mixed with food and medicines, which increases the number of sorting steps and the probability of increased contamination. On the other hand, the contact area between small packages of preservatives and the air in the container is small, and the effect is slow, resulting in unsatisfactory preservation effect.

A sealing film is arranged at the bottom opening of the cover body for limiting and sealing the fresh-keeping material.

[0007] As a further solution of the utility model: the inner wall of the concave cavity is provided with an adhesive layer for bonding and fixing the fresh-keeping material.

[0008] As a further solution of the utility model: a buckle is arranged inside the recessed cavity for fixing the fresh-keeping substance.

[0009] As a further solution of the utility model: a breathable film is arranged on one side of the sealing film close to the concave cavity.

[0010] As a further solution of the utility model: the sealing film is made of polymer material and can achieve the sealing effect of water and oxygen isolation.

[0011] As a further solution of the utility model: a clamping groove is arranged at the edge of the cover body, and the inner diameter of the clamping groove is matched with the opening edge of the container.

[0012] As a further solution of the utility model: the outer diameter of the card slot is matched with the inner edge of the opening of the container.

[0013] As a further solution of the present invention: the sealing film covers the opening of the recessed cavity.

[0014] As a further solution of the utility model: the sealing film completely seals the cover body in the form of a bag.

[0015] The beneficial effects of the utility model are as follows: the cover body is placed at the opening of the container and is compatible with the bottle, no additional bottle needs to be provided, and the subsequent use of the original container cover is not affected; the fresh-keeping substance is fixed in the cover body, which effectively reduces the influence of the substance in the container on the fresh-keeping substance, and can give full play to the function of the fresh-keeping substance; the fresh-keeping substance is not mixed with the substance in the container, which can avoid the situation where the fresh-keeping substance and the substance in the container come out together, and there is no need to sort the fresh-keeping substance from the substance in the container.
