Technical Field

[0001] This utility model relates to the field of food packaging technology, and in particular to a multi-layer stacked food combination packaging. Background Technology

[0002] As people's living standards improve, health supplements have become an indispensable part of people's lives. Many health supplements are packaged in small bottles, which are convenient to carry and help users take only what they need, clearly defining the dosage for each serving or daily, thus avoiding overdose. Small bottles are usually designed with a good sealing cap or easy-tear film, effectively preventing moisture and light from entering, and are also convenient for the elderly and children. Small bottles are also more economical. Users can purchase according to their needs, reducing waste, and are convenient to carry, minimizing secondary contamination after opening.

[0003] Currently, the small square bottles used for food packaging are all individually packaged. When users buy a large quantity, they are scattered and inconvenient to carry, especially when traveling. Moreover, they take up limited luggage space. Some foods use a large bottle with several small bottles scattered inside, but the large bottle is also inconvenient to carry when traveling and takes up limited luggage space as well. Utility Model Content

[0004] To address the problems of existing health food products using small, individually packaged square bottles, which are inconvenient to carry when purchased in large quantities, especially for travel, and take up valuable luggage space, this invention provides a multi-layered food packaging system. By incorporating a circular groove at the bottom of the bottle and a matching cylindrical top on the cap, multiple square bottles can be sequentially and tightly fitted together to form a single, integrated structure. This design facilitates easy carrying and solves the problems of traditional individual small square bottles, which are cluttered and take up valuable luggage space. Furthermore, the stacked bottles can be of various colors, creating a vibrant and aesthetically pleasing display, enhancing the product's perceived quality and brand image, and attracting consumer attention.

[0005] To achieve the above objectives, this utility model provides a multi-layer stacked food packaging, comprising several square bottles stacked sequentially from top to bottom. Each square bottle includes a cap, a bottle body, and a sealing film. The bottle body is characterized by: an open top and rounded corners on all edges; an upward-extending inner stop on the upper surface and a circular groove on the lower surface; the sealing film is heat-sealed onto the upper surface of the bottle body to seal the inner cavity, and is an easy-tear film; the cap has a square opening at the lower end that mates with the inner stop, a cylindrical top at the upper end, and a transitional arc surface in the middle; the square opening fits into the inner stop, with the inner diameter of the square opening tightly fitting into the outer diameter of the inner stop; the outer diameter of the cylindrical top fits into the inner diameter of the circular groove; and in two adjacent square bottles, the circular groove of the upper bottle fits into the cylindrical top of the lower bottle, with the circular groove and cylindrical top tightly fitting together.

[0006] Furthermore, the upper outer surface of the inner stop is provided with an outwardly extending flange, and an annular groove is formed between the flange and the lower step surface of the inner stop. The inner side wall of the square opening at the lower end of the bottle cap is provided with waist-shaped ribs, which cooperate with the annular groove to lock together, making it difficult for the bottle cap to loosen from the bottle body.

[0007] Furthermore, the outer wall of the bottle is designed as a square cone, wider at the top and narrower at the bottom, with a taper of 1.5 to 2 degrees.

[0008] Furthermore, the outer wall of the square opening at the lower end of the bottle cap is a square cone with a smaller top and a larger bottom, and the taper is set to 1.5 to 2°.

[0012] Furthermore, several stacked square bottles of different colors form a colorful combination of packaging bottles; several stacked square bottles can be aligned or rotated at a certain angle to avoid being aligned.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a circular groove at the bottom of the bottle and a matching cylindrical top on the bottle cap, allowing multiple square bottles to be connected into a single structure by sequentially fitting the upper circular groove at the bottom of the bottle with the lower cylindrical top of the bottle cap. This makes the bottles easy to carry and solves the problem of traditional small square bottles being individually packaged, scattered, and taking up limited luggage space. 2. This utility model forms an annular groove on the inner stop by setting a flange and a waist-shaped rib, so that the annular groove and the waist-shaped rib can fit together and engage, making the bottle cap and bottle body firmly connected and not easy to loosen. 3. The bottle cap of this utility model adopts a transitional arc surface design that represents the concept of yin-yang balance, comprehensive conditioning, and auxiliary treatment in traditional Chinese medicine. 4. The square bottles of this utility model, which are stacked together, can be of various colors, making them colorful, beautiful in appearance, enhancing the product grade and brand image, and attracting consumers' attention.
