Colloid packaging structure

Abstract

The invention discloses a colloid packaging structure. The colloid packaging structure comprises a main packaging tube, an upper piston, a lower piston and a spray nozzle, wherein the upper piston isin sliding and sealing fit to the inner wall of the main packaging tube; the lower piston is sliding and sealing fit to the inner wall of the main packaging tube; a mouth tube is arranged on the mainpackaging tube; a piston tube which communicates with the inner part of the main packaging tube is arranged on the upper piston; the piston tube passes through the mouth tube; a return spring is arranged in the mouth tube; the lower end of the return spring is relatively fastened with the mouth tube; the spray nozzle comprises a lower seat tube which communicates with the piston tube and an upperspray tube which communicates with the lower seat tube; the lower end of the lower seat tube is in contact with the upper end of the return spring; the lower seat tube sleeves outside the piston tube;and the lower end of the lower seat tube is positioned in the mouth tube. The colloid packaging structure has the beneficial effects that: the structure is reasonable, colloids such as toothpaste canbe quickly and effectively extruded out, operations are simple and efficient, colloid residues inside are fewer after the colloids are used out, and waste can be effectively reduced. The colloid packaging structure is strong in structure relevance, realizes all functions of lid-opening, discharging, returning and the like by actions of pressing and releasing, and is simple and efficient to operate.

Description

technical field [0001] The invention belongs to the technical field of colloidal packaging, and in particular relates to a colloidal packaging structure. Background technique [0002] In production and life, colloids such as toothpaste are mainly stored in the packaging structure for use. Among them, the packaging structure of squeeze toothpaste (soft toothpaste tube) is relatively common, and it has the advantages of convenient use. However, although the current toothpaste can be discharged and used by extrusion, it is necessary to pay attention to the position of extrusion each time, otherwise it is easy to have the problem of material at both ends of the soft toothpaste tube and lack of material in the middle. And during use, the direction of the toothpaste in the soft toothpaste tube is not easy to control, and the toothpaste needs to be pushed from the tail to the head artificially. In addition, after use, the problem of a lot of toothpaste residue on the inner wall of...

Problems solved by technology

However, although the current toothpaste can be discharged and used by extrusion, it is necessary to pay attention to the position of extrusion each time, otherwise it is easy to have the problem of material at both ends of the soft toothpaste tube and lack of material in the middle. And during use, the direction of the toothpaste in the soft toothpaste tube is not easy to control, and the toothpaste needs to be pushed from the tail to the head artificially. In addition, after use, the problem of a lot of toothpaste residue on the inner wall of the soft toothpaste tube is also unavoidable. of
