[0034] As a preferred embodiment, the cup holder of the bottom cup can be an equilateral triangle, a square, a regular hexagon, etc., which can realize close packing. As described in the present application, when HSL or EVA is used as the heat-sealing layer, the connection strength still meets the use requirements when the cup holder of the bottom cup is a regular hexagon, the area of the cup holder can be relatively reduced to save materials, and it is more convenient to use the straight drinking method when the cover film is removed.

[0035] The specific embodiments of the present application will be further described in conjunction with the drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present application, and cannot be used to limit the protection scope of the present application.

[0036] Example

[0037] Please refer to Figs. 1-3The yogurt cup with lid is made of a single polyester material, comprising a lid film 10 and a bottom cup 20, wherein the lid film 10 is sequentially provided with a surface film 11, a middle film 12 and an inner film 13; the surface film 11 is a PET film, the middle film 12 is an MPET film or a foamed PET film, the inner film 13 is provided with a HSL coating or an EVA coating, the surface film 11 is dry compounded with the middle film 12, and the inner film 13 is coated on the surface of the middle film 12; the bottom cup 20 comprises a cup body 21 and a cup holder 22 arranged on the top surface of the cup body 21, and both are made of a cast APET; the lid film 10 and the cup holder 22 are connected by heat sealing through the coating on the inner film 13. The coating amount of HSL or EVA is adjusted between 2-10g / m2 according to the required peeling force, wherein the dry compounding refers to that the two-component polyurethane glue is coated on the surface of the middle layer according to the requirement at 3-5g / m2, and then the middle film and the upper film are glued together by a compression roller at a pressure of 5-10bar.

[0038] The printing film 14 is arranged between the surface film 11 and the middle film 12 of the lid film 10, and the printing film 14 is a BOPET film. The outer surface of the bottom cup 20 is further provided with a label layer 23, and the label layer 23 is a BOPET layer.

[0039] The yogurt cup comprises a plurality of bottom cups 20, the plurality of bottom cups 20 are connected by the cup holders 22 and are integrally formed. The adjacent cup holders 22 are provided with two easy-to-tear grooves 24 arranged in an up-down staggered manner, and the grooves are provided with serrations 25. The adjacent cup holders can also be connected in a point-breaking mode. The outer periphery of the cup holder is a regular polygon, and the outer periphery of the regular polygon is protruded to form a circular arc.

[0040] The working principle of the utility model lies in, the cover film 10 is composed of multiple layers of film, forms a stable composite structure, plays a role of blocking, protection and the like. A printing film 14 (BOPET film) is arranged between the surface film 11 and the middle layer film 12, which can provide a good bearing surface for printing patterns, identification and other information, facilitate the display of relevant content on the cover film, and also help to further optimize the lamination effect between the films, making the entire cover film structure more stable. The inner layer film 13 adopts HSL coating or EVA coating and is coated on the surface of the middle layer film 12, which can be connected with the cup holder 22 of the bottom cup 20 by heat sealing. When performing yogurt filling and other operations, under certain temperature and pressure conditions, the inner layer film 13 is heat sealed and connected with the cup holder 22, ensuring good sealing between the cover film and the bottom cup, preventing yogurt leakage, and ensuring the freshness and hygiene safety of the product. The bottom cup 20 includes a cup body 21 and a cup holder 22, both of which are made of cast APET. This material selection ensures that the bottom cup has certain strength, toughness and transparency, which can meet the needs of containing yogurt and allowing consumers to directly observe the yogurt inside the package. The label layer 23 (BOPET layer) can print product-related information such as production date, shelf life, ingredient list, nutritional composition table, brand logo, eating method, etc. on it, making it easy for consumers to understand product details. At the same time, the label layer is preferably made of opaque or even ultraviolet-resistant material, which does not affect the visibility of consumers and also reduces the damage of ultraviolet rays to the probiotics in the yogurt, meeting the relevant regulatory requirements of food packaging. Adjacent cup holders 22 are provided with a tear groove 24, and two tear grooves are arranged in an upper and lower staggered manner. The groove is also provided with a sawtooth 25. Such a design is to facilitate consumers to easily tear a single bottom cup from the connected cup along the tear groove when using the yogurt connected cup, without the need for additional tools, improving the convenience of use. At the same time, the upper and lower staggered design of the tear groove and the sawtooth design make the tearing process smoother, reducing the occurrence of irregular tearing or excessive force leading to yogurt spilling. Adjacent cup holders are connected in a point-cutting manner, and the outer periphery of the cup holder is a regular polygon and protrudes to form an arc. On the one hand, it ensures that multiple bottom cups are integrally formed and connected with each other when not in use, facilitating packaging, transportation and storage; on the other hand, the design of the regular polygon and the arc conforms to the principle of ergonomics, making consumers more comfortable when holding a single bottom cup, and the appearance is also more beautiful, more attractive.

[0041] The above only describes preferred embodiments of the utility model, and it should be noted that for ordinary technical personnel in the technical field, without departing from the technical principles of the utility model, a number of improvements and refinements can be made, and these improvements and refinements should also be considered within the protection scope of the utility model.
