Wax-sealed spherical shell

Abstract

The invention belongs to the technical field of drug and food packaging and specifically relates to a wax-sealed spherical shell. The wax-sealed spherical shell provided by the invention is composed of a bottom shell and a facial shell, wherein a head part of the buckling tongue of the bottom shell is a wedge-shaped buckling round edge; a neck part of the buckling tongue is equipped with an annular body flange; and an annular body inclined gap is cut in a shoulder part of the buckling tongue. After buckling of the bottom shell and the facial shell, an open inclined cut-in whole-body groove is formed at the buckling part. A groove line, a raised line, a concave point part or a convex point part are disposed in the annular body inclined gap of the shoulder part of the bottom shell buckling tongue or in the groove formed between the wedge-shaped buckling round edge and the annular body flange. After wax sealing, the wax ring does not suffer from brittle fractures easily; and sealing effects are good.

Description

technical field [0001] The invention belongs to the technical field of medicine and food packaging, in particular to a wax-sealed spherical shell. 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 when gently pinched; after conventional wax s...

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.
