AI Technical Summary

Technical Problem

Existing liquid food packaging bags are prone to sedimentation during storage and transportation, which affects the quality and taste of the food. Existing technologies also suffer from problems such as complex structure, high cost, and poor stability.

Method used

An inner and outer bag structure was designed. The inner bag is equipped with a shaking mechanism and an anti-sedimentation mechanism. The inner bag is made of a combination of rigid and soft bag bodies, while the outer bag is made of rigid material. The soft bag body is vibrated by the shaking of the spring and ball and the flow of liquid to prevent the accumulation of sediment.

Benefits of technology

It effectively prevents liquid food from settling, ensuring food quality and taste, and improves the stability and practicality of the packaging bag, adapting to different storage and transportation conditions.

Abstract

This utility model discloses a liquid food packaging bag with an anti-sedimentation structure, relating to the technical field of liquid food packaging bags. The technical solution includes an inner bag and an outer bag disposed outside the inner bag. The inner bag is used to hold the liquid food, and a U-shaped sealed cavity is formed between the inner and outer bags. A threaded circular opening is provided at the top center of the inner bag, and a sealing cap is threaded onto the opening. A shaking mechanism is provided at the bottom of the inner bag, comprising a spring and a ball. An anti-sedimentation mechanism is also provided within the sealed cavity. The beneficial effects of this utility model are: by setting up the shaking mechanism and the anti-sedimentation mechanism, the liquid food is effectively prevented from settling in the packaging bag. The shaking mechanism utilizes the structure of the spring and ball; when the packaging bag is vibrated, the shaking of the spring and ball agitates the liquid food, preventing sediment accumulation. The anti-sedimentation mechanism generates vibration in the soft bag body due to the flow of the liquid.
