Embodiment Construction

[0011] The invention discloses a roof carton cover, which is composed of an inner cover and an outer cover. Its main technical feature is that the inner cover is a hollow cylinder 2 with threads 7 on the outside, which is similar to a common threaded bottle mouth. The bottom of the cylinder 2 is formed with a connecting plate 1, which can be made into a circular shape. The connecting plate 1 is connected with the roof carton 8, and the two are connected through a special process. The mouth of the cylinder 2 has a sealing diaphragm 3, and the sealing diaphragm is made Handle 4 is arranged, and sealing diaphragm seals to round mouth, and handle (ear) uncapping is used, and sealing gasket 6 is installed in outer cover 5, is used as sealing by outer cover sealing gasket after sealing diaphragm is torn off. Its described sealing diaphragm 3 and handle 4 are made of aluminum film, and the special aluminum film is integrally punched and molded, and the aluminum film sealing film 3 is ...

Abstract

A cover unit for the roof-type paper box is composed of internal and external covers. Said internal cover is a hollow cylinder with external spiral thread, bottom board connected to paper box, and sealing top membrane with pull ring. Said external cover has the internal sealing pad.

Description

technical field [0001] The invention relates to a box cover for packaging beverages (such as milk) in a roof-top carton, belonging to the field of food packaging. Background technique [0002] In beverage (such as milk, juice, etc.) packaging, more and more materials and manufacturing types are used, and roof cartons are one of them. Because the package looks like a roof (the upper two sides are slopes, and the middle spire is raised), and the paper is light-shielding, it is widely used in beverage packaging such as milk, but the existing products are usually tear-off or straw-type. Once opened, it must be used up once. The straw type has a socket, and the intubation is used for drinking, because the intubation cannot be sealed once it is inserted, and it must be used up at one time. And the shelf life of existing products is generally shorter. Therefore, the shortcoming of existing technology is that once opened, it must be used up once, and it is n...
