Description

Technical Field

[0001] This utility model belongs to the field of flexible tube packaging technology, specifically relating to a plastic-reducing integrated packaging container. Background Technology

[0002] Currently, most tube packaging on the market, especially for toothpaste, ointment, cosmetics, food, and pet food, typically consists of three separate components: the tube body (main body), a screw-on or snap-on cap / shoulder, and a separate flip-top or screw-on cap. This type of tube packaging design inherently suffers from material waste and functional defects.

[0003] (1) Waste of materials and processes: After the hose body is produced, the shoulder / head is injection molded. After the whole assembly is completed, the flip cap or screw cap is rotated or snapped together. The production process is complicated, which increases the investment in equipment, the amount of materials used, the labor processing cost and the logistics cost.

[0004] (2) Excessive use of plastic: Although the amount of material used in the cover (especially PP or HDPE plastic) may not seem large individually, the sheer volume of billions of units consumed constitutes a huge source of plastic waste, which contradicts the concept of environmental sustainability. In many areas, due to inadequate recycling systems, these small plastic covers are easily missed during sorting and end up in the natural environment or landfills.

[0005] Although the patent with application number CN202221965279.3 also discloses an integrated container, its tube body and tube shoulder are integrally molded, and the flip cover is connected to the tube shoulder as an independent component through a pivot. The assembly process is complicated, and the flip cover is not designed according to the outline of the discharge port on the tube shoulder, but according to the outline of the entire tube shoulder, resulting in a large amount of plastic material used. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects of the prior art and provide a plastic-reducing integrated packaging container. The integrated molding of the flip cover and the shoulder simplifies the production process. The flip cover is designed with an expanded edge according to the size of the discharge port of the shoulder, which reduces the use of plastic. It can be made of a single material, which is convenient for recycling and granulation, and is beneficial to environmental protection.

[0007] The technical solution to achieve the above objective is: a plastic-reducing integrated packaging container, comprising a tube body, a tube shoulder, and a flap, wherein the flap and the tube shoulder are integrally injection molded, and the lower opening of the tube shoulder is connected to the upper opening of the tube body.

[0008] The shoulder of the tube has an upwardly protruding outlet in the middle, and one side of the flip cover is connected to one side of the outlet. A sealing post is provided on the lower surface of the flip cover, and a sealing boss is provided at the bottom end of the sealing post. A sealing latch is provided on the inner wall of the outlet to match the sealing boss. The flip cover covers the outlet, the sealing post is inserted into the outlet, and the sealing boss is engaged with the sealing latch below.

[0009] In the aforementioned one-piece packaging container for reducing plastic use, the edge of the flap has a downwardly protruding flange, and when the flap is closed on the discharge port, the flange of the flap covers the outside of the discharge port.

[0010] The aforementioned one-piece packaging container for reducing plastic use, wherein the other side of the flap has an outwardly extending flap brim.

[0011] In the aforementioned one-piece packaging container for reducing plastic use, the shoulder of the tube has a clearance groove, which is located below the connection between the flap and the discharge port.

[0012] In the aforementioned one-piece packaging container for reducing plastic use, the connection between the flap and the discharge port adopts an I-shaped connection structure or a flexible butterfly-shaped connection structure.

[0013] In the aforementioned one-piece packaging container for reducing plastic use, the lower opening of the tube shoulder and the upper opening of the tube body are assembled by welding or injection molding.

[0014] The aforementioned one-piece packaging container for reducing plastic use, wherein the shoulder and the flap are made of the same material.

[0015] The aforementioned one-piece packaging container for reducing plastic use, wherein the tube body, tube shoulder, and flap are made of the same material.

[0016] The plastic-reducing integrated packaging container of this utility model has the following technical advantages compared with the prior art:

[0017] (1) Adopting a plastic reduction and integrated structure: The traditional independent cover is eliminated. The flap and the tube shoulder are integrally molded and then connected to the tube body to form an inseparable whole, reducing the use of independent plastic parts; the flap is designed to be compressed according to the discharge port on the tube shoulder, reducing the use of plastic.

[0018] (2) Improve user experience: The operation can be completed by flipping open the cover with one hand and squeezing the tube body, avoiding the risk of contamination that may occur after the traditional independent cover is removed;

[0019] (3) Easy to recycle and environmentally friendly: On the one hand, it can be made of a single material, which is easy to recycle: Due to the simplified structure, it is easier to use the same type of plastic (such as PE or PP material) for the tube body, tube shoulder and flip cover, which increases the value of the entire packaging when it is recycled. There is no need to separate the parts in a complicated way, and it can be directly crushed and granulated. On the other hand, it reduces the carbon footprint: It reduces the amount of raw materials used and the manufacturing and assembly processes, which fundamentally reduces the overall carbon footprint of the product.
