Bottle cap component with material barrel arranged in cap

Abstract

The invention relates to a bottle cap component with a material barrel arranged in a cap and belongs to a container sealing device. The bottle cap component comprises a bottle cap and a bottleneck which are in thread fit. The material barrel is arranged in the bottle cap, and enough space for accommodating the thickness of the bottleneck is left between the material barrel and bottle cap threads. An opening of the material barrel faces towards the bottle neck and is sealed by a detachable sealing plate. The bottle cap component is characterized in that back supporting sheets are arranged on the periphery of the sealing plate, and blocking bars are arranged at positions of the inner wall of the bottleneck, which are corresponding to the positions of the back supporting sheets. According to the bottle cap component, 'materials and water are separated', devices such as cutters are not needed, and the material barrel and the bottle cap are integrated, so that space is not wasted, and transportation is convenient; besides, the material barrel can be opened in the bottle through a bottle opening action, so that the bottle cap component is sanitary and convenient.

Description

technical field [0001] The invention relates to a container cap, in particular to a rotary bottle cap of a bottle, such as a bottle cap of a beverage bottle. Background technique [0002] A common beverage bottle cap assembly is composed of a bottle cap and a bottle mouth. The bottle mouth and the bottle body are connected to each other. The bottle cap and the bottle mouth are usually threaded and can be unscrewed or tightened. There are also plug-and-plug types, but in the field of beverages, considering repeated use and sealing effects, the threaded rotary type is the mainstream. [0003] The traditional bottle caps that are directly screwed have relatively high manufacturing requirements and need to ensure airtightness. Generally, the technical means adopted are that the bottom of the bottle cap is provided with a sealing groove, and the upper end of the bottle mouth is screwed into the sealing groove to achieve sealing. The requirement of this design is to ensure that t...

Problems solved by technology

[0009] Although the above-mentioned prior art integrates a cutting knife, it is convenient to cut the sealing paper, but the cutting knife is arranged outside the bottle cap, which is unhygienic and unsafe; more importantly, the material box containing the powder needs to be opened after the bottle cap is opened. Cutting with a knife is neither convenient nor hygienic
