TW202103612A - Cold drink cup and manufacturing method thereof can be eaten and do not increase garbage - Google Patents

Abstract

The disclosure comprises a cup. The cup has a cup body. The cup body has an accommodation space and an opening upwardly disposed and communicating with the accommodation space. The cup body is composed of an edible starch base structure, an edible waterproof oil containing coated layer and a waterproof thin film, wherein the starch base structure composes a main body of the cup body, and an inner side of the starch base structure is coated with the waterproof oil containing coated layer. An outer side of the starch base structure is encapsulated with the waterproof thin film. Accordingly, the accommodation space can contain cold drinks for drinking, and within drinking time limit of cold drink, it can prevent cold drink from permeating into the starch base structure through oil water separation structure of the waterproof oil containing coated layer. The waterproof thin film can prevent the starch base structure from absorbing condensed water. Moreover, the starch base structure and the waterproof oil containing coated layer can be eaten after completing the drinking of cold drink and removing the waterproof thin film so as to reduce garbage.

Description

Cold drink cup and manufacturing method thereof

The invention relates to a cold drink cup, in particular to a structure and a manufacturing method of the cold drink cup.

Cold drinks are quite popular beverages, especially the freshly brewed cold drinks provided for take-out have a better taste, and can adjust the sugar and ice cubes according to the needs of each person, and are widely welcomed by consumers. It is known to fill cold drinks with the cup as disclosed in Taiwan Announcement No. M575793. However, it is a disposable container. After the cold drink is finished, the disposable container can only be treated as garbage.

In order to reduce the amount of garbage, some people use stainless steel cups and other containers that can be reused after washing to fill cold drinks. They use reusable cups instead of disposable cups to reduce the amount of garbage and make a distraction for environmental protection. .

However, in actual use, it often happens that consumers want to buy cold drinks but do not carry stainless steel cups, so they can only use disposable cups; for the beverage industry, the use of stainless steel cups is good for environmental protection. , But it will increase the working time and increase the cost, and once the stainless steel cup is not cleaned, there will be more food hygiene and safety issues.

In this regard, the main purpose of the present invention is to disclose a disposable cold drink cup that is edible without increasing the amount of garbage.

The secondary objective of the present invention is to disclose a method for manufacturing a cold drink cup that is disposable and edible without increasing the amount of garbage.

The present invention is a cold drink cup comprising a cup, wherein the cup has a cup body, the cup body has an accommodating space and an opening, the opening is arranged upward and communicates with the accommodating space, and the cup body is formed by a The starch base structure, a water- and oil-repellent coating and a water-repellent film are formed, and the starch-based structure is an edible food material and is used to form the main body of the cup. The water and oil-repellent coating is also an edible food material, And the water-resistant and oil-containing coating coats the inner side of the starch base structure, and the water-repellent film is a waterproof material, and the water-repellent film covers the outer side of the starch base structure.

The manufacturing method of the cold drink cup of the present invention includes: step S1: shaping, step S2: coating, and step S3: coating.

The first step is step S1: shaping, forming the starch base structure by heating a starch solution with a mold.

Next is step S2: coating, heating a water-repellent and oil-containing material that is solid at room temperature, pour the water-repellent and oil-containing material in a liquid state on the inner side of the starch base structure, and after cooling, on the starch base structure The water- and oil-repellent coating is formed on the inner side.

The last step is step S3: coating, the starch base structure with the water-resistant and oil-containing coating is placed in a water-resistant plastic shrink bag, and the starch base structure is sent to a hot air blower to allow the water-resistant plastic The shrink bag shrinks to form the water-resistant film, so that the water-resistant film covers the outer side of the starch base structure.

Accordingly, the accommodating space of the present invention can be used to contain cold drinks for drinking, and during the drinking period of the cold drinks, the present invention uses the oil-water separation structure of the water-resistant and oil-containing coating to prevent cold drinks from penetrating into the starch substrate The water barrier film can prevent the starch base structure from absorbing condensed water; and after the water barrier film is removed after the cold drink is consumed, the starch base structure and the water barrier oil-containing coating are available for consumption, thereby reducing garbage the amount.
