Abstract
Description
Technical Field
[0001] The present invention relates to a food container structure, and more particularly to a food container structure that allows the liquid level or contents inside the food container to be visible from the outside.
Background Art
[0002] Conventional storage containers are cups for storing liquids, which are utensils that can easily store liquids such as water and drinks and have an opening at the top. However, when storing liquids, it was difficult to know the liquid level of the liquid stored in the cup because the liquid could only be observed from the opening provided above. In particular, drinks at drink stands widely popular in Taiwan have their drinking mouths covered with film by a sealer machine, so it is impossible to check the remaining amount of the drink in the cup and the contents (such as tapioca, nata de coco, fruits, etc.), which is inconvenient and improvement has been demanded. Conventional paper containers for storing cooked food (such as bento boxes) are storage containers integrated with flip-type covers, and after storing food, the lid can be quickly closed. However, since the appearance of this paper container is the same, the contents can only be confirmed by marking a symbol on the upper surface, writing the name of the contents by hand, or opening the lid to check. When distributing bentos, it was inconvenient.
[0003] In view of the above-mentioned drawbacks of the prior art, the present inventor has conducted intensive research and as a result, has completed a food container structure that can improve the problems of the prior art.

At least one transparent plastic film 13 is attached inside the above-described container body 11 to cover the hollowed-out part 12. When the above-described container body 11 contains a liquid, the liquid level or contents inside the above-described container body 11 can be seen through the hollowed-out part 12, and the above-described plastic film 13 can prevent the liquid or contents from leaking out through the hollowed-out part 12.
[0010] On the inner and outer walls of the above-described container body 11, a single layer of PE (Polyethylene) coat is formed so that the container body 11 can contain cold and hot drinks and prevent the contained drinks from soaking or leaking.
[0011] Inside the above-mentioned container body 11, a transparent plastic film 13 is pasted. The plastic film 13 has a first side A and a second side B. On the first side A, a food-grade PE layer made of a transparent material is formed. On the second side B, a food-grade PP (Polypropylene) layer made of a transparent material is formed. The PE layer on the first side is bonded to the PE coating layer on the inner wall of the container body 11 to form a form of bonding homogeneous PE materials, and the cut-out part 12 on the surface of the container body 11 is sealed by high-frequency thermocompression bonding. The PP layer on the second side B touches the side of the food, obtaining good transparency and effects such as oil resistance, anti-seepage, anti-puncture, and dew condensation prevention, preventing dew condensation from occurring and water droplets from being generated by the cold and hot drinks contained in the container body 11, and obtaining high perspective.
[0012] Refer to FIGS. 1 to 4. As shown in FIGS. 1 to 4, the appearance of the food storage container 10 included in the food storage container structure according to an embodiment of the present invention may be a cup container. On the above-mentioned cut-out part 12, a scale may be provided so that the volume of the liquid contained in the container body 11 can be known.
[0013] Refer to FIG. 5. As shown in FIG. 5, the cut-out part 12 of the food storage container structure according to an embodiment of the present invention is formed into a figure, which may have good appearance and effects such as trademarks, brands, and images.
