Wax-sealed spherical shell with zigzag buckling structure

Abstract

The invention belongs to the technical field of drug and food packaging and specifically relates to a wax-sealed spherical shell with a zigzag buckling structure. The wav-sealed spherical shell provided b the invention is characterized in that a head part of a bottom shell buckling tongue is a zigzag buckling round edge; an annular body inclined gap is cut on a neck part of the buckling tongue; a facial shell comprises a tongue-shaped round edge; an annular body groove is formed in the inner side of the tongue-shaped round edge; the facial shell body and the tongue-shaped round edge of the facial shell form a zigzag groove which is matched with the zigzag buckling round edge of the head part of the bottom shell buckling tongue; and after buckling of the facial shell and the bottom shell, an open inclined cut-in whole-body annular groove is formed in the buckling part. In comparison with the prior art and existing products, the wax-sealed spherical shell has the advantages that the buckling degree is high; the wax-sealed layer does not suffer from brittle fractures easily; and the sealing degree is high.

Description

technical field [0001] The invention belongs to the technical field of medicine and food packaging, and in particular relates to a wax-sealed spherical shell with a zigzag fastening structure. Background technique [0002] At present, the existing wax-sealed spherical shells are mostly used for pill packaging, and are generally composed of two hemispherical shells. After the pills are loaded, the two hemispherical shells are tightly fastened by means of slots or threads. Seal with hot wax. For example, the pill protective shell disclosed in Chinese patent documents CN2759468Y and CN202699601U adopts the form of a slot to fasten two half-shells, and the disclosed pill protective shell of CN2772501Y adopts screw connection, and the pills currently on the market are also mostly wax-sealed spherical shells using these forms. The tongues on the surface of these spherical shells are relatively thin, and after being fastened to the bottom shell, there will be clutches or loosening...

AI Technical Summary

Problems solved by technology

The tongue on the surface shell of these spherical shells is relatively thin, and after being fastened with the bottom shell, it will be clutched or loosened if it is gently pinched; after conventional wax sealing, such as dipping in wax, the surface can be wrapped with a layer of wax coat, and the buckle is fastened. The tight buckle seam hinders the infiltration of wax liquid, so the thin wax coat is easy to be brittle, and the inside and outside of the spherical shell are connected through the brittle crack, so that the contents cannot be effectively sealed and protected.
