ENVASE A VACIO, ADAPTABLE AL EMPLEO DE ATMOSFERAS MODIFICADAS, PARA PRODUCTOS ALIMENTICIOS DE CONSUMO UNITARIO Y SISTEMA PARA SU FABRICACION

摘要

Vacuum package, adaptable for use in modified atmospheres, for single-service food consumption and the manufacturing system for producing the package. This is a plastic container for vacuum packaged food products and is adaptable for use in modified atmospheres, which allows for consumption of part of the product without exposing the remaining part of the product to the environment. This is achieved by individualizing the product in separate heat sealed chambers. The heat seal between the different parts of the product serves as a barrier that separates the units that one wishes to consume. The upper part of the container includes a heat sealed section to prevent breakage, followed by a perforated line and a part without heat sealing to facilitate opening the units of food. There are also a number of hollow triangles in this zone. The vertex of the triangles coincides with the perforated line that separates the units of food. The purpose of these triangular perforations is to facilitate the separation between each unit. This container can contain a variable number of product units depending on its size and the needs of the consumer. The individual units of the container can also be sold separately by retail sellers. In such a case, the anti-breakage heat seal on the top of the container would not be necessary. The number of the container's product units is also limited by the capacity of the secondary container (normally a cardboard box) used for distribution and handling.
