Description

New type O-shaped easy-to-buckle sealing cap for round cans

technical field

The utility model relates to a cover for a packaging can containing solid powder, in particular to a novel O-shaped easy-to-buckle sealing cover.

Background technique

The O-shaped cover is mainly used for the traditional composite cover structure of the milk powder can, that is, the aluminum film and the ring cover are combined through the mechanical structure of the equipment and formed with the can body to form a roll-sealing structure for sealing and protection. The current O-shaped lid is made of plastic material, and the thickness of the material used for the entire lid is uniform, with a thickness of about 0.8~1.0mm. This type of plastic lid is used for milk powder cans with easy-to-tear or snap-on lids due to their thinner thickness. After the can, the aluminum foil in the middle part needs to be removed. When the milk powder can is used again, the isolation layer between the can and the outside world is only the plastic cover part, and the plastic cover is thinner and has poor air insulation performance. If the material with poor shading properties is used, the outside light will directly shine The contents of the tank can easily lead to deterioration or contamination of the contents of the tank.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a new O-shaped easy-to-buckle sealing cover for round cans that can be opened and used conveniently and can provide better sealing.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: the new round tank O-shaped easy-to-buckle sealing cover includes a cover body, and an O-ring cover is arranged on the cover body, and the O-ring cover is clamped with the cover body. The ring is provided with a sealing ring matching the outer diameter of the tank body, and the outer ring of the O-ring cover is provided with an inner sealing ring matching the inner diameter of the ring cover on the tank body. It is characterized in that: the thickness of the cover body located above the ring cover is 2 to 3 times the thickness of the rest of the body. The utility model is designed with a sealing device at the outer ring of the cover, the joint of the outer ring of the O-ring cover and the tank body, which ensures the sealing performance and the fastness of the cover. The cover body is only thickened in the center, which solves the shortcomings of ordinary plastic covers that are too thin in air insulation and poor light-shielding properties, and effectively protects the contents. At the same time, it ensures the tightness of the plastic cover and the fastness of the buckle cover, and the plastic is easy to open, saving costs.

The cover body described in the utility model is made of PP or PE material. PP or PE material can ensure the tightness of the lid and the can body, facilitate the opening of the lid, and facilitate cost control.

Compared with the prior art, the utility model has the following advantages: the thickening of the middle part of the cover of the utility model can effectively prevent the deformation caused by repeated use of the new cover, the stress is relatively uniform, and the sealing performance is not affected by repeated use; To effectively isolate the contents from the external environment, prevent problems such as decomposition, agglomeration, deterioration, etc. caused by long-term exposure to harsh conditions such as sunlight and light; it can effectively protect the outer layer and prevent scratches or damage due to transportation and use , causing problems such as decomposition, agglomeration, deterioration, etc. of the contents. The utility model has double protection, not only through the sinking of the thickened part of the middle part of the cover body, but also utilizing the double sealing protection of the inner sealing ring.

Detailed ways

Referring to Fig. 2 to Fig. 3, the utility model includes a cover body 3, an O-ring cover 2 is arranged on the cover body 3, and the O-ring cover 2 is clamped with the cover body 3. The outer ring of the cover body 3 is provided with a sealing ring 4 matching the outer diameter 5 of the tank body 1, and the outer ring of the O-ring cover 2 is provided with an inner sealing ring 6 matching the inner diameter of the upper ring cover 7 of the tank body 1. The thickness of the part 9 of the cover body 3 located above the ring cover 7 is 2 to 3 times the thickness of the remaining part 8 of the cover body 3 . In order to ensure the tightness between the cover 3 and the can body 1 and to facilitate the opening of the cover 3, the cover 3 in this embodiment is made of PP or PE.

The assembly method of the utility model: when the utility model easy-button sealing cover is in use, the cover body 3 is placed on the top of the tank body and pressed in to cover, and at the same time the cover body sealing ring 4 is closely matched with the outer diameter of the tank body 5, and the cover body ring cover 2 The inner sealing ring 6 on the top is closely matched with the can body ring cover 7, and the can body ring cover 7 is provided with a sealing aluminum foil to ensure the sealing and integrity of the product when it is not opened. When the can needs to be opened for use, the contents can be taken out by tearing the sealed aluminum foil after opening the easy-buckle lid. Just press it in, it is easy to use and can effectively ensure the quality of the contents from being affected by the external environment, playing a good protective role.

The above content described in this specification is only an illustration of the structure of the present utility model. Those skilled in the technical field to which the utility model belongs can make various modifications or supplements to the described specific embodiments or adopt similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the definition defined in the claims scope, all should belong to the protection scope of the present utility model.
