Definitions

• the present invention relates to a variable package for a mobile product, which has an internal pressure receiving portion, and more particularly, to a variable package having an internal pressure receiving portion for a mobile product whose end can be easily varied by vacuum packing or increase of an internal pressure so as to allow the vacuum packing to be performed in the package itself, thereby improving an efficiency in a sterilization process, and to allow the mobile product to be cooked without separately opening the package, thereby reducing a cooking time and also minimizing loss of flavor of the mobile product.
• a mobile product is a kind of product in which liquids of food in a package are heated by a cooking means like a microwave oven so that the food is cooked.
• a cooking means like a microwave oven
• the package may be deformed or burst by internal pressure which is increased according as the liquids of food are evaporated.
• the vacuum packing is the most efficient.
• sterilization efficiency is lowered by a limited space and also the package may be deformed by a negative pressure of air discharged in the vacuum packing process. Disclosure of Invention
• An object of the present invention is to provide a variable package for a mobile product, which has an internal pressure receiving portion for preventing the package from being shrunk and deformed by discharge of air in the package upon a vacuum packing process and also preventing the package from being burst by evaporating of liquids in food and thus increasing of internal pressure so as to allow the vacuum packing to be performed in the package itself, thereby improving an efficiency in a sterilization process, and to allow the mobile product to be cooked without separately opening the package, thereby reducing a cooking time and also minimizing loss of flavor of the mobile product.
• a variable package for a mobile product comprising an internal package having an internal pressure receiving portion which is integrally formed at a side of the package so as to be shrunk by discharge of internal air of the package during a vacuum packing process and expanded by change of an internal pressure of the package and thus to prevent the package from being burst by the change of the internal pressure of the package.
• variable package having the internal pressure receiving portion for the mobile product comprises an external package which is coupled so as to enclose the internal package for preventing the other portions of the internal package except the internal pressure receiving portion from being deformed undesirably and allowing the package to be easily stood on a horizontal surface.
• a length of a lower end of the external package is formed to be longer than a vertical length of the internal pressure receiving portion when the internal pressure receiving portion is expanded.
• variable package having the internal pressure receiving portion for the mobile product comprises a lower coupling part which is coupled to a lower portion of the external package so as to keep appendages necessary to eat the food in a space between the shrunk internal pressure receiving portion and a bottom surface of the external package.
• FIG. 1 is a perspective view of a package according to an embodiment of the present invention.
• FIG. 2 is an exploded perspective view of Fig. 1.
• FIGS. 3 to 7 are cross-sectional views showing packing and cooking processes using the package of Fig. 1. Best Mode for Carrying Out the Invention
• Fig. 1 is a perspective view of a package according to an embodiment of the present invention
• Fig. 2 is an exploded perspective view of Fig. 1, which shows a detail structure of the package having an internal pressure receiving portion for a mobile product. That is, the package of the present invention includes an internal package 10, an external package 20 and a lower coupling part 30.
• the internal pressure receiving portion 10a functions to provide a margin space for improving sterilization efficiency during a vacuum packing process and also prevent the internal package 10 from being burst by increasing of internal pressure during a cooking process.
• the internal pressure receiving portion 10a is formed integrally with the internal package 10 so as to form a single space together with an internal space of the internal package 10 and also it is constructed so as to prevent the other portions of the package except the internal package 10 from being shrunk and deformed by discharge of air in the internal package 10 upon the vacuum packing process and prevent the internal package 10 from being burst by evaporating of liquids in food 10c during the cooking process and thus increasing of the internal pressure.
• the external package 20 functions to prevent the other portions of the internal package 10 except the internal pressure receiving portion 10a from being undesirably deformed and also to support the package so as to easily stand the package on a horizontal surface.
• a length (m2, referring to Fig. 7) of a lower end of the external package 20 is formed to be longer than a vertical length (ml, referring to Fig. 7) of the internal pressure receiving portion 10a when the internal pressure receiving portion 10a is expanded and thus to enclose the internal package 10.
• the internal package 10 may be formed with an adhesive layer at an upper part thereof and then fixedly coupled to the external package 20.
• an external diameter of the external package 10 and an internal diameter of the internal package 20 are properly designed so as to fit the internal package 10 into the external package 20 without the adhesive.
• FIGs. 3 to 7 are cross-sectional views showing packing and cooking processes using the package of Fig. 1.
• the packing and cooking processes of the variable package having the internal pressure receiving portion 10a for a mobile product will be described with reference to the drawings.
• the food 10c to be packed is placed in the internal package 10 which is integrally formed with the internal pressure receiving portion 10a so as to form the single space along with the internal space of the internal pressure receiving portion 10a.
• the external package 20 is coupled to the internal package 10, and an upper portion of the internal package 10 is sealed with a lid film 10b (herein, for the vacuum packing, the internal package 10 is sealed to be partially opened), and then the vacuum packing process is performed using a vacuum device.
