Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, specifically to an ice cup structure. Background Technology

[0002] With the fast pace of life, consumers want to enjoy refreshing drinks anytime, anywhere. Edible ice cups meet consumers' needs for ready-to-eat and DIY cold drinks, and are therefore favored by consumers.

[0003] Currently, most ice cups on the market consist of a plastic cup, an inner liner, and a plastic lid, which presents some problems during use. Pressure differences at different altitudes cause the cup to expand, potentially leading to inner liner cracking or the bottom of the cup bulging.

[0004] Therefore, how to solve the above problems has been a concern for those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide an ice cup structure that can reduce the risk of damage due to expansion.

[0006] This application provides an ice cup structure, including:

[0007] The cup body includes a cup body and a cup bottom, the cup body and the cup bottom forming a receiving cavity, and the end of the cup body away from the cup bottom has a cup rim, the cup rim forming an opening of the cup body;

[0008] A membrane body is attached to the side of the cup body away from the bottom of the cup to cover the opening, and the membrane body is partially separated from the rim of the cup.

[0009] In this embodiment, the membrane is partially separated from the rim of the cup. When the ice cup structure is located at different altitudes and there is a pressure difference, the internal air pressure of the cup increases. The gas in the containment cavity will push the membrane up, and a fluid channel will be formed between the membrane and the rim of the cup. The gas in the containment cavity will flow to the outside through the fluid channel between the membrane and the rim of the cup, realizing automatic depressurization of the containment cavity and greatly reducing the occurrence of membrane bulging and damage caused by cup expansion.

[0010] In one example, the surface of the cup rim facing away from the bottom of the cup includes a connecting portion and a non-connecting portion. The connecting portion is heat-sealed to the membrane, and the non-connecting portion is separately disposed from the membrane.

[0011] In one example, the non-connecting portion is provided with a notch, the notch including an opening and a bottom wall portion, and the size of the opening portion is larger than the size of the bottom wall portion along the circumference of the cup rim.

[0012] In one example, the height of the notch ranges from 0.01 mm to 0.1 mm.

[0013] In one example, the number of connecting portions and the number of non-connecting portions are both greater than or equal to two, and the connecting portions and non-connecting components are arranged alternately in the circumferential direction.

[0014] In one example, the surface of the membrane facing the opening has a honeycomb structure.

[0015] In one example, the cup bottom includes a connected support portion and a recessed portion, the recessed portion being recessed towards the receiving cavity.

[0016] In one example, the diameter of the bottom surface of the cup is greater than or equal to 4.5 mm, and the height of the recess ranges from 0.2 mm to 0.8 mm.

[0017] In one example, the recess is an arched structure that extends to the cup body, and there are two supports that are symmetrically arranged about the recess.

[0018] In one example, the cup also includes a lid that snaps onto the rim of the cup, the membrane being located inside the lid, and a gap between the lid and the rim. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solutions of the embodiments of this application, the embodiments of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the ice cup structure provided in one embodiment of this application; Figure 2 for Figure 1 A cross-sectional view of the ice cup structure shown; Figure 3 for Figure 1 A top view of the body of the ice cup shown in the diagram; Figure 4 for Figure 1 Enlarged schematic diagram of point A in the structure of the ice cup shown; Figure 5 for Figure 1 The diagram shows a bottom view of the membrane in the ice cup structure.

[0028] This application provides an ice cup structure, including a cup body, a membrane 2, and a lid. The cup body and lid can be made of plastic. The cup body can be a cylinder, such as a prism or a frustum, such as a truncated cone or a truncated pyramid. Of course, the cup body can also be other shapes, which will not be described in detail here.

[0029] In this embodiment, the cup body includes a cup body 1 and a cup bottom 3, which together form a receiving cavity 1A. The end of the cup body 1 furthest from the cup bottom 3 has a cup rim 4. The cup rim 4 can be a flanged structure with a large contact surface, resulting in a larger contact area between the flanged structure and the membrane 2, making it easier to fix the membrane 2, and ensuring a firm connection between the cup rim 4 and the membrane 2. Alternatively, the cup rim 4 can also be an end face with the same thickness as the cup body 1.

[0030] In this embodiment, the membrane 2 is connected to the side of the cup body 1 away from the bottom 3 to cover the opening. The membrane 2 can be a plastic membrane. The membrane 2 and the cup rim 4 can be fixed by heating. Of course, the membrane 2 and the cup rim 4 can also be fixed by adhesive or other means.

[0031] In this embodiment, the membrane 2 and the cup rim 4 are partially separated. When the ice cup structure is located at different altitudes and there is a pressure difference, the internal air pressure of the cup body 1 increases. The gas in the receiving cavity 1A will push the membrane 2 up. A fluid channel is formed between the membrane 2 and the cup rim 4 at a local position. The gas in the receiving cavity 1A will flow to the outside through the fluid channel between the membrane 2 and the cup rim 4, realizing automatic pressure relief of the receiving cavity 1A, which greatly reduces the occurrence of membrane 2 bulging and breaking due to cup expansion.

[0032] In this embodiment, the surface of the cup rim 4 facing away from the bottom of the cup includes a connecting portion 42 and a non-connecting portion. The connecting portion 42 is heat-sealed to the membrane 2, and the non-connecting portion is separately disposed from the membrane 2. A gas flow channel can be formed between the non-connecting portion and the membrane 2. The heat-sealing connection is simple and reliable.

[0033] In this design, the number of connecting parts and the number of non-connecting parts are both greater than or equal to two, and the connecting parts and non-connecting parts are arranged alternately along the circumference. The figure shows two non-connecting parts located between two connecting parts.

[0034] In this embodiment, the non-connecting portion is provided with a notch 41, which includes an opening and a bottom wall. Along the circumference of the cup rim 4, the size L1 of the opening is larger than the size L2 of the bottom wall. That is, the non-connecting portion has a structure with a large upper opening and a small lower opening. Under normal conditions, this structure facilitates the membrane 2 covering the notch 41. When the gas pressure inside the receiving cavity 1A increases, the gas can push open the membrane 2 and flow out rapidly from the notch 41, thus achieving pressure relief.

[0035] If the height H of the notch 41 is too large, heat seal collapse and poor sealing may occur. If the height of the notch 41 is too small, the heat-sealing film 2 will stick firmly to the cup rim 4, failing to provide pressure relief. In this embodiment, the height of the notch 41 ranges from 0.01mm to 0.1mm, for example, 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, or 0.1mm. A notch 41 within this height range satisfies both pressure relief and heat sealing requirements.

[0036] In this embodiment, the surface of the membrane 2 facing the opening has a honeycomb structure 21. The honeycomb structure 21 can be fixed to the membrane 2 by bonding or heat fusion, and the honeycomb structure 21 is the optimal topological structure for covering a two-dimensional plane. The honeycomb structure 21 is the basic structure of a honeycomb, which is a structure composed of hexagonal single cells, with all openings facing downwards or to one side, arranged symmetrically back to back. Of course, the basic unit in the honeycomb structure 21 is not limited to hexagons, but can also be other structures with cavities. The honeycomb structure 21 can reduce the damage to the membrane 2 caused by the impact of ice, improve the problem of the membrane 2 being punctured by ice during circulation and transportation, and improve the customer experience.

[0037] The stability of the ice cup structure is also an issue that is easily overlooked by those skilled in the art. This application also proposes a structure that can improve the stability of the ice cup structure.

[0038] In this embodiment, the cup bottom 3 includes a connected support portion 31 and a recessed portion 32. The recessed portion 32 is recessed towards the receiving cavity 1A and is located in the central region of the cup bottom 3. In this embodiment, the recessed portion 32 in the central region of the cup bottom 3 can improve the strength of the cup bottom 3 to a certain extent. The recessed portion 32 can prevent the cup bottom 3 from bulging outward in the center and causing unevenness, thus improving the stability of the cup bottom 3 when placed. At the same time, it can improve the overall quality and aesthetics of the product.

[0039] In this embodiment, the diameter of the bottom surface of the cup bottom 3 is greater than or equal to 4.5 mm, and the height of the recessed portion 32 ranges from 0.2 mm to 0.8 mm. If the recessed height of the recessed portion 32 is less than 0.2 mm, the recessed part of the cup bottom 3 is easily pushed out, causing the cup bottom 3 to be unstable. If the recessed height of the recessed portion 32 is greater than 0.8 mm, it wastes resources.

[0040] In this embodiment, the recessed portion 32 has an arched structure that extends to the cup body. Two support portions 31 are symmetrically arranged about the recessed portion 32. This structure provides high stability to the cup bottom 3 and also has a more aesthetically pleasing appearance.

[0041] In this embodiment, the cup lid is fastened to the cup rim 4, the membrane 2 is located inside the cup lid, and there is a gap between the cup lid and the cup rim 4 or a through hole on the cup lid, so that the gas in the receiving cavity 1A can flow out from the membrane 2 and the cup rim 4 and then leave to the external environment through the through hole of the cup lid or the gap between the cup lid and the cup rim 4.

[0042] The cup lid can protect the membrane 2 to a certain extent, preventing environmental objects from expanding with the membrane 2 and reducing damage to the membrane 2.

[0043] Although the cup lid is not shown in the accompanying drawings, it does not prevent applicants in the art from understanding the above-described technical solutions.

[0044] In the description of embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0045] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
