Description

Technical Field

[0001] This utility model belongs to the field of packaging container technology, and in particular relates to a reusable paste packaging structure. Background Technology

[0002] Ointments, a common form in daily chemical products, pharmaceuticals, and personal care products such as toothpaste, medicated ointments, lip balms, and skin creams, are widely used and prevalent. Their packaging structure plays a crucial role in ensuring the safety of the contents, preventing leakage, avoiding contamination, and facilitating storage and precise dosage. Good packaging not only affects product shelf life and user experience but also hygiene and convenience during use. The structural design, material selection, and lifespan of packaging are increasingly becoming key concerns for consumers, with ever-increasing demands for functionality and durability.

[0003] However, existing ointment packaging structures mostly use single-layer or composite tubes, integrally molded from materials such as aluminum-plastic or plastic, and fitted with a screw-on or plug-in cap to form a sealed container. During production, the ointment is directly filled into the tube and then sealed, resulting in a high degree of integration between the packaging and its contents. After use, this type of packaging is essentially unusable for reuse because residues are difficult to remove completely and the composite materials are not easily separated. Users typically discard the entire package as waste, which not only leads to a large consumption of raw materials such as plastics and aluminum but also increases the pressure on solid waste disposal. Long-term accumulation has an adverse impact on the ecological environment and hinders the efficient use of resources and sustainable development of packaging.

[0004] Therefore, there is a particular need for a reusable ointment packaging structure to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing ointment packaging which is a single-use structure and cannot be reused after use, resulting in resource waste and increased waste, and is not conducive to environmental protection and sustainable development, this utility model provides a reusable ointment packaging structure.

[0006] This utility model is achieved through the following technical means: a reusable paste packaging structure, including an aluminum shell plate, a bottom shell, a lid, a cardboard plate, paste, and a push plate. The aluminum shell plate serves as the outer main structure, the bottom shell is inserted into the lower part of the aluminum shell plate, the lid is attached to the upper part of the aluminum shell plate, and the cardboard plate serves as the inner main structure, placed inside the aluminum shell plate. The cardboard plate has an overall cylindrical open structure, and the push plate is slidably placed inside the cardboard plate. The cardboard plate is filled with paste, and the top surface of the push plate is in close contact with the bottom of the paste.

[0007] As an improvement to the above solution, the aluminum shell is made of high-strength aluminum.

[0008] As an improvement to the above solution, a damping pad is provided on the outer wall of the bottom shell that contacts the aluminum shell plate.

[0009] As an improvement to the above solution, both the bottom shell and the cover are made of the same aluminum material as the aluminum shell plate.

[0010] As an improvement to the above solution, an annular limiting structure is provided at the bottom of the bottom shell to hold the bottom of the paperboard.

[0011] As an improvement to the above solution, the paperboard is made of multi-layer composite material.

[0012] As an improvement to the above solution, the lower part of the cardboard board is also provided with an annular limiting structure, which locks the bottom edge of the push plate.

[0013] As an improvement to the above solution, the top of the paste is kept flush with the top of the cardboard.

[0014] As an improvement to the above scheme, the shape of the top surface of the push plate is matched with the inner cavity of the paperboard.

[0015] Beneficial effects: By setting up a double-layer structure consisting of an aluminum shell and a cardboard shell, the packaging achieves modular and reusable design. The inner cardboard shell serves as a disposable inner liner and can be replaced as a whole after the paste is exhausted, while the outer aluminum shell serves as a durable outer shell that can be reused for a long time, reducing resource consumption and waste generation, which is in line with the concept of environmental protection and sustainable development.

[0022] Example: A reusable ointment packaging structure, such as Figures 1-5As shown, the structure includes an aluminum shell 1, a bottom shell 2, a cover 3, a cardboard shell 4, a paste 5, and a push plate 6. The aluminum shell 1 serves as the outer main structure and is made of high-strength aluminum, possessing excellent structural rigidity, corrosion resistance, and aesthetic appeal, allowing for long-term reusability. The bottom shell 2 is inserted into the lower part of the aluminum shell 1. A damping pad, made of elastic rubber or silicone, is provided on the outer wall of the bottom shell 2 in contact with the aluminum shell 1. This damping pad significantly increases the friction between the outer wall of the bottom shell 2 and the lower inner wall of the aluminum shell 1, preventing... The bottom shell 2 is designed to prevent accidental detachment or loss during use or transport, thus improving structural stability. The cover 3 is attached to the upper part of the aluminum shell plate 1. Both the bottom shell 2 and the cover 3 are made of the same aluminum material as the aluminum shell plate 1, maintaining a consistent appearance and enhancing the overall texture and durability. The paper shell plate 4 serves as the inner main structure and is placed inside the aluminum shell plate 1. The paper shell plate 4 has an open cylindrical structure. The annular limiting structure at the bottom of the bottom shell 2 holds the bottom of the paper shell plate 4 in place, thereby confining the entire paper shell plate 4 inside the aluminum shell plate 1. To prevent it from shifting up and down or detaching from the aluminum shell 1 during use, the paper shell 4 is made of a multi-layer composite material, such as a polyethylene heat-sealing layer, a paper base layer, and a polyester and aluminum foil barrier layer distributed from the inside out. A push plate 6 is slidably placed inside the paper shell 4. The top surface shape of the push plate 6 matches the inner cavity of the paper shell 4, thereby sealing the lower opening of the paper shell 4. The lower part of the paper shell 4 is also provided with an annular limiting structure, which locks the bottom edge of the push plate 6 to prevent the push plate 6 from being disassembled. The push plate 6 slides out from the bottom of the cardboard plate 4. It can only be removed from the top opening of the cardboard plate 4 after the cardboard plate 4 is disassembled. The push plate 6 has a circular groove to facilitate the user's hand to apply force. The cardboard plate 4 is filled with paste 5. The top of the paste 5 is flush with the top of the cardboard plate 4. The top surface of the push plate 6 is in close contact with the bottom of the paste 5. In the initial state, the push plate 6 is located at the lowest position inside the cardboard plate 4. By pushing from bottom to top, the paste 5 is gradually pushed upward to achieve the controllable ejection of the paste 5.

[0023] When using, the user pulls off the cap 3 to expose the paste 5, and then pushes the push plate 6 upward. The push plate 6 squeezes the paste 5 and pushes the paste 5 out of the cardboard 4. At this time, the user can apply the paste 5 to the skin or other application areas. After use, the cap 3 should be closed in time to prevent the paste 5 from being exposed to contamination or drying.

[0024] When the paste 5 is used up, the user pulls the bottom shell 2 downwards to detach it from the bottom of the aluminum shell 1, thus completing the disassembly of the bottom shell 2. At this time, the paper shell 4 loses its limit and can be taken out from inside the aluminum shell 1. After taking out the paper shell 4, continue to push the lifting plate 6 upwards to make it exit from the opening at the top of the paper shell 4. Discard the paper shell 4 that has been used up.

[0025] After cleaning and thoroughly drying the aluminum shell 1, bottom shell 2, lid 3, and push plate 6, reassembly can be performed: First, place the push plate 6 into the new cardboard shell 4 and seal the lower opening of the cardboard shell 4. Then, fill the cardboard shell 4 with new paste 5 until the paste 5 is flush with the top of the cardboard shell 4. Next, insert the cardboard shell 4 filled with paste 5 into the aluminum shell 1. Finally, re-insert the bottom shell 2 into the lower part of the aluminum shell 1, pressing against the bottom of the cardboard shell 4 to complete the overall assembly. The entire packaging structure is restored to its initial state and can be used again.
