Abstract
Description
Technical Field
[0001] The invention relates to the technical field of packaging devices, in particular to a multi-angle linkage packaging device. Background Art
[0002] Pre-prepared meals refer to finished or semi-finished meals made from agricultural products, livestock and poultry, aquatic products, etc., with various auxiliary materials, and pre-processed (such as cutting, mixing, marinating, tumbling, shaping, seasoning, quick freezing, and freezing). They are convenient, fresh, and healthy. The rich choice of dishes and flexible cooking and eating methods can meet the different needs of different groups of people for food. The raw materials required for the production of pre-prepared meals mainly include meat and poultry, aquatic products, soy products, fruits and vegetables, and condiments. Depending on the different ingredients, pre-prepared meals can be divided into pastries, vegetables, livestock and poultry, and aquatic products. Therefore, the upstream of the pre-prepared meal industry is agricultural products, poultry farming, animal husbandry, aquaculture and fishing, vegetable and fruit planting, and condiment production industries, and the downstream is the consumer market, catering market, and food processing market. The definition of pre-prepared meals: using one or more agricultural products as the main raw materials, using standardized assembly line operations, and being pre-processed (such as: cutting, mixing, marinating, rolling, kneading, forming, seasoning, etc.) or pre-cooked (such as stir-frying, deep-frying, baking, boiling, steaming, etc.), and pre-packaged finished or semi-finished dishes. For pre-prepared meals, the industry has not yet formed a very unified and standard definition. According to the standards of the China Food Industry Association, pre-prepared meals refer to dishes made from one or more food raw materials and auxiliary materials, with or without auxiliary materials such as seasonings (including food additives), and processed through pre-selection, modulation, forming, packaging, quick freezing, etc., and stored, transported, and sold under cold chain conditions. It is a full-meal-level solution between self-cooking and take-out, and between food and catering;
[0003] At present, when preparing pre-prepared dishes, if the quantity is large, the materials are stored, which may easily cause the pre-prepared dishes inside to overflow, causing a certain amount of waste and inconvenience in cleaning, resulting in poor use effect.
