Damp-proof packaging box for chrysanthemum

Abstract

This utility model discloses a moisture-proof packaging box for Chuzhou chrysanthemums, relating to the field of packaging box technology. This solution provides a stable and dry storage environment for dried Chuzhou chrysanthemum petals through the sliding engagement of a protruding retaining ring and a ring-shaped top cover, combined with the tight contact between the sealing inner ring and the upper edge of the protruding retaining ring. The force is transmitted through a foldable extension connecting rod and a damping rotating shaft, pushing the sliding bottom ring upwards. This not only compresses the inner packaging bag to reduce air retention and decrease the space for moisture adhesion, but also allows the Chuzhou chrysanthemums to gather upwards, improving retrieval efficiency. The inner packaging bag is confined between the flexible contact ring and the sliding bottom ring, ensuring stable fixation during compression and preventing excessive squeezing that could damage the petals, thus protecting the product's appearance. Furthermore, the replaceable moisture-absorbing bag inside the ring-shaped top cover continuously absorbs internal moisture through the breathable structure of the perforated retaining ring. The moisture-absorbing bag is easy to replace and can maintain the moisture-proof effect for a long time, extending the shelf life of the Chuzhou chrysanthemums.

Description

Technical Field

[0002] Chuzhou chrysanthemum, as the top of China's four famous chrysanthemums (Chuzhou chrysanthemum, Hangzhou chrysanthemum, Bozhou chrysanthemum, and Huai chrysanthemum), is also a national geographical indication protected product. Its packaging box not only undertakes the basic function of protecting the product, but also serves as an important carrier of brand image, cultural value, and product grade.

[0003] A breathable packaging box, patent number CN202346058U, mainly comprises a box body and a lid. The lid is located on top of the box body, and several ventilation holes are provided on two sides of the box body. These ventilation holes allow outside air to enter the chrysanthemum tea packaging box, expelling any unpleasant odors produced inside. This type of chrysanthemum tea packaging box will not produce unpleasant gases even under long-term sealed conditions, thus not affecting the quality of the chrysanthemum tea inside.

[0004] Existing packaging for Chuzhou chrysanthemums mostly uses ordinary cardboard boxes, plastic bags, or containers with a single sealed structure, which are significantly inadequate in terms of moisture protection. The internal space of the packaging is fixed, and as the amount of Chuzhou chrysanthemums decreases, the remaining gaps increase, and excessive air retention easily breeds moisture, further exacerbating the risk of Chuzhou chrysanthemums spoiling.

[0023] Through the force transmission of the foldable extension connecting rod 5 and the damping rotating shaft 6, the sliding bottom ring 4 is pushed upward, which can compress the inner packaging bag 9 of Chuzhou chrysanthemum to reduce air retention and reduce moisture adhesion space, and also make the dried petals of Chuzhou chrysanthemum gather upward, improving the efficiency of the next use. The operation is flexible and adaptable to different usage scenarios.

[0024] Please see Figures 1-4The inner packaging bag 9 of Chuzhou chrysanthemum is located between the flexible contact ring 17 and the sliding bottom ring 4. The threaded top cover 10 is located above the center point of the limiting outer ring 16. The upper end of the cylindrical outer packaging box 1 is fixedly connected with a protruding retaining ring 2. The upper end of the inner wall of the ring-shaped top cover 3 is fixedly connected with a sealing inner ring 11. The protruding retaining ring 2 and the ring-shaped top cover 3 slide and engage. The sealing inner ring 11 and the upper part of the protruding retaining ring 2 abut against each other. The inner end of the inner packaging bag 9 of Chuzhou chrysanthemum is filled with several dried petals of Chuzhou chrysanthemum. The inner wall of the inner packaging bag 9 of Chuzhou chrysanthemum is fixedly connected with a tin foil moisture-proof inner layer 18.

[0025] Please see Figures 2-3 The cylindrical outer packaging box 1, through the sliding engagement of the protruding retaining ring 2 and the ring-shaped top cover 3, combined with the tight contact between the sealing inner ring 11 and the protruding retaining ring 2, forms a reliable primary seal. The tin foil moisture-proof inner layer 18 of the Chuju chrysanthemum inner packaging bag 9 and the sealing design of the threaded top cover 10 construct a secondary moisture barrier. The double protection effectively blocks the intrusion of external moisture, ensuring a dry storage environment for Chuju chrysanthemum. Furthermore, the inner packaging bag 9 is confined between the flexible contact ring 17 and the sliding bottom ring 4, ensuring stable fixation when lifted and compressed, avoiding excessive squeezing that could damage the petals, and effectively protecting the appearance and quality of Chuju chrysanthemum.

[0028] The working principle of this utility model is as follows: In this solution, the cylindrical outer packaging box 1 serves as the main supporting structure. Its upper end is slidably engaged with the ring-shaped top cover 3 via a protruding retaining ring 2. The sealing inner ring 11 on the inner side of the ring-shaped top cover 3 abuts against the upper edge of the protruding retaining ring 2, forming a primary seal to prevent external moisture from entering. The Chuzhou chrysanthemum inner packaging bag 9 is placed inside the cylindrical outer packaging box 1. The tin foil moisture-proof inner layer 18 on its inner wall can enhance the moisture-proof performance of the inner packaging itself. The upper end is sealed by the threaded top cover 10 to ensure that the dried Chuzhou chrysanthemum petals are isolated from external moisture. After taking out the Chuzhou chrysanthemum, the non-slip grip ring 7 can be held to apply force. The foldable extension connecting rod 5 transmits force through the damping pivot 6, pushing the sliding bottom ring 4 to slide upward along the inner wall of the cylindrical outer packaging box 1, causing the Chuzhou chrysanthemum inner packaging bag 9 to be lifted and compressed. This compression not only This design reduces air retention between the inner packaging bag 9 and the cylindrical outer packaging box 1, minimizing moisture adhesion space. It also helps to gather the dried chrysanthemum petals upwards for easier retrieval next time. The inner packaging bag 9 is confined between the flexible contact ring 17 and the sliding bottom ring 4 inside the cylindrical outer packaging box 1, ensuring stable fixation of the inner packaging bag 9 when lifted, preventing excessive compression that could damage the chrysanthemum petals. Meanwhile, the connecting crossbar 12 on the inner side of the ring-shaped top cover 3 fixes the hollow storage ring 13. The lower end of the hollow storage ring 13 is engaged with a replaceable moisture-absorbing bag 15 via a hinged perforated clip 14. The moisture-absorbing bag continuously absorbs moisture from inside the cylindrical outer packaging box 1 through the breathable structure of the perforated clip 14. Combined with the tin foil moisture-proof inner layer 18 and the multi-level sealing structure, a double moisture-proof system is formed to ensure that the dried chrysanthemum petals are kept in a dry environment, preventing them from becoming damp and deteriorating.
