Definitions

  • the present invention relates to a packaged food which is produced by enclosing unfrozen or frozen food in an airtight container such that the packaged food can be directly cooked by heating in a microwave oven.
  • the present invention also relates to a container for packaging food in which the aforementioned food can be enclosed for storage.
  • the present invention intends to provide, in an economical manner, a sealing structure in which a hole-sealing sheet for sealing a vent hole formed in a container for packaging food automatically comes off, at the most preferable timing, when the food is cooked by heating by an microwave oven.
  • a first object of the present invention is to provide a packaged food, in which a hole-sealing sheet covering a vent hole formed at a portion of a container is not so easily peeled off when the container is preserved at the room temperature or the freezing condition but the hole-sealing sheet automatically comes off, when the food is heated by an microwave oven, substantially at the time when the food contained in the container has reached an adequately cooked state.
  • a second object of the present invention is to provide a container for packaging food, which container is provided with at least one vent hole and used for producing packaged food by enclosing food therein, and in which container a hole-sealing sheet covering the vent hole is not so easily peeled off when the container is preserved at the room temperature or the freezing condition but the hole-sealing sheet automatically comes off, when the food is heated by an microwave oven, substantially at the time when the food contained in the container has reached an adequately cooked state. That is, the second object of the present invention is to provide a container for packaging food which enables carrying out the most preferable heating of the food by flexibly adapting, in function thereof, to the various heating conditions by a microwave oven which is selected according to the contained food.
  • the packaged food of the present invention which can achieve the aforementioned first object, is characterized in that food containing water or an aqueous solution is enclosed in a container, the container having, on one side thereof, a surface portion made of plastic sheet, at least one vent hole being formed in the vicinity of the center of the surface portion, the vent hole being sealed by an adhesive hole-sealing sheet whose vertical peeling strength is no less than 1 N/cm in the temperature range of 40° C. or lower and is no higher than 0.1 N/cm at the temperature range of 80° C. or higher.
  • the container for packaging food of the present invention which can achieve the aforementioned second object, is characterized in that the container has, on one side thereof, a surface portion made of plastic sheet, at least one vent hole being formed in the vicinity of the center of the surface portion, the vent hole being sealed by an adhesive hole-sealing sheet whose vertical peeling strength is no less than 1 N/cm in the temperature range of 40° C. or lower and is no higher than 0.1 N/cm at the temperature range of 80° C. or higher.
  • the hole-sealing sheet of the container for packaging food of the present invention is preferably made of white chemical paper used as a base material. It is preferable that the vent hole formed in the container is sealed by the hole-sealing sheet such that the adhesive layer having uneven width provided in the hole-sealing sheet covers the periphery of the vent hole.
  • FIG. 1 is a sectional view of a vent hole portion formed in a lid of a container for packaging food of the present invention.
  • FIG. 2 is a perspective view which shows a structure of a container for packaging food of the present invention.
  • Packaged food of the present invention is intended to represent packaged food which can be cooked by heating by a microwave oven.
  • At least one vent hole is provided in a container for packaging food so that, when the pressure inside the container is increased in heating the food due to volume increase in the air in the container and generation of steam, the increased pressure is reduced by releasing the steam and occurrence of explosion is prevented.
  • the vent hole is sealed by a hole-sealing sheet having adhesives thereon. That is, the present invention has been achieved by utilizing and improving the conventional technique.
  • the inventors of the present invention have assiduously studied a problem that it is not easy to make the preferable finished state of cooking by heating correspond with the pressure resistance properties of the hole-sealing sheet.
  • the inventors have discovered that the pressure resistance properties of the hole-sealing sheet can be changed by adjusting the temperature properties of adhesive strength of the adhesive agent (the adhesive agent is used for attaching the hole-sealing sheet).
  • the present invention has been achieved on the basis of this discovery.
  • the container for packaging food of the present invention may have a box-like shape or a bag-like shape. That is, the shape of the container is not limited to any particular form and any structure is acceptable as long as the container is formed by using a material which is excellent in airtight, watertight, oil resistant and heat resistant properties, is electromagnetic wave-transmittable, and has mechanical strength of appropriate level. However, at least one side surface of the container must be formed by a plastic sheet. The surface formed by a plastic sheet is preferably transparent so that the content therein can be seen.
  • plastic material to be used for forming the container as described above examples include: a single material sheet or a composite material sheet containing, as main components, polypropylene, polyester, polysulfone, polyamide (nylon), polycarbonate and the like; and a laminated layer-composite sheet in which the aforementioned single material or composite material sheet is combined with polyacrylate, polyvinylidene chloride, polyvinyl alcohol and the like.
  • a vent hole is formed in the plastic sheet surface made of the aforementioned materials.
  • the vent hole is preferably formed in the vicinity of the center of the container for packaging food (in the vicinity of the center of the upper surface, in a case of a flat-type container in which the height is relatively small as compared with the longitudinal/lateral dimensions thereof) in terms of evenly heating the content in the container.
  • the vent hole may have any shape such as circular, ellipsoidal, oval or polygonal shape, as long as the shape is suitable for the purpose.
  • the size of the diameter of the vent hole is preferably 5 mm or so, but is not particularly limited.
  • the hole-sealing sheet for sealing the vent hole is preferably made of a base material having excellent airtight, watertight, oil resistance and heat resistance properties.
  • a base material include a sheet made of polyester, polypropylene or the like, a synthetic paper and a chemical paper made of plastic materials.
  • the hole-sealing sheet itself hardly generates heat when it is hit by electromicrowaves nor increases its temperature when it absorbs infrared light.
  • the hole-sealing sheet having aluminum deposited thereon so as to reflect microwaves and the hole-sealing sheet which is colorless or, in particular, white is especially preferable.
  • the hole-sealing sheet may have any suitable shape such as circular or ellipsoidal shape.
  • the size of the diameter of the hole-sealing sheet is preferably 10 mm or so, but it not limited to this size.
  • the adhesive agent for attaching the hole-sealing sheet to the vent hole formed in the plastic sheet must be an adhesive agent having stickiness with respect to the plastic sheet, i.e., a pressure sensitive adhesive.
  • a pressure sensitive adhesive agent include natural rubber, synthetic rubber.
  • a pressure sensitive adhesive which is produced by blending styrene butadiene-based rubber and acryl-based rubber with a rosin-based or petroleum resin-based stickiness-providing material so as to have both excellent pressure sensitive properties and excellent thermosensitive properties, is particularly preferable for use.
  • the pressure sensitive adhesive as described above is required to have thermosensitive properties in which the vertical peeling strength is no less than 1 N/cm or preferably no less than 2 N/cm in the temperature range of 40° C. or lower and is no higher than 0.1 N/cm in the temperature range of 80° C. or higher.
  • the numerical values in the aforementioned conditions are not such numerical values which are inherent to the adhesive itself as is obtained by measurement in accordance with the standard adhesive strength testing method and the like practiced in the industry (described in JIS Z 0237, for example), but the numerical values which indicate the thermosensitive properties of adhesive strength of the hole-sealing sheet, with respect to the plastic sheet of a container for packaging food having a vent hole formed therein. Accordingly, attention should be paid because it is generally not known whether or not a pressure sensitive adhesive, which satisfies the aforementioned conditions of adhesive strength properties with respect to a specific polyester sheet, also satisfies the conditions of adhesive strength properties with respect to a specific nylon 6 sheet.
  • the aforementioned conditions of adhesive properties are to be applied to a container for packaging food which is designed for accommodating the most common food, i.e., the food which contains water or aqueous solutions at appropriate ratios and is suitable for heating by an microwave oven.
  • the most common food include cooked food such as main meal, snack, half-cooked food and the like. Therefore, with respect to the food which needs to be heated to a relatively high temperature of no lower than 100° C. or the food which needs to be heated only to 40-60° C., it is necessary that a pressure sensitive adhesive having more preferable adhesive strength properties within the aforementioned range of the conditions, is selected. Yet further, needless to say, food which is not suitable for being heated by an microwave oven such as dry foods or the like is beyond the scope of the present invention.
  • the reference number 1 represents a food container which is produced by molding a polycarbonate sheet.
  • a laminate layer or the like formed by an appropriate material may be provided inside the food cotainer 1 .
  • the reference number 2 represents a flexible lid made of nylon 6 sheet.
  • the periphery portion of the lid 2 is designed so that the periphery portion can be fixed to the edge portion 1 ′ of the food container 1 by melt-attaching or adhesive-attaching.
  • a vent hole 3 having circular shape is formed in the vicinity of the center position of the lid 2 .
  • the vent hole 3 has been airtightly sealed by the hole-sealing sheet 4 having circular shape.
  • a pressure sensitive adhesive layer 5 which sticks to the nylon 6 sheet is provided on the back surface of the hole-sealing sheet 4 , such that a non-adhesive portion 5 ′ having ellipsoidal shape is formed substantially in the center portion of the pressure sensitive adhesive layer 5 .
  • the width of the portion coated with the pressure sensitive adhesive is made uneven. Further, the center position of the vent hole 3 does not need to coincide with that of the hole-sealing sheet 4 .
  • a slight misalignment of 1-2 mm or so between the center position of the vent hole 3 and that of the center position of the hole-sealing sheet 4 is rather preferable because such a slight misalignment facilitates, in a reliable manner, peeling of the hole-sealing sheet 4 .
  • the hole-sealing sheet 4 used here is produced by: preparing, as a base material, synthetic paper made of polyester which has thickness of 60 ⁇ m and white surface coating applied thereon; and coating the base material with an acryl-based pressure sensitive adhesive a so that the thickness of the adhesive a is 25 ⁇ m, thereby forming the pressure sensitive adhesive layer 5 .
  • a hole-sealing sheet 4 b and a hole-sealing sheet 4 c were produced by coating the base material with another acryl-based pressure sensitive adhesive b or a styrene butadiene-based pressure sensitive adhesive c, respectively, so that the thickness of the adhesives b, c is each 25 ⁇ m and the pressure sensitive adhesive layer is formed in each of a hole-sealing sheet 4 b and a hole-sealing sheet 4 c in a manner similar to the hole-sealing sheet 4 a.
  • the packaged food of the present invention prepared by using the container for packaging food of the present invention reliably prevents, when the packaged food is heated by a microwave oven, the hole-sealing sheet thereof from peeling off at the time when the food has not sufficiently been heated.
  • the hole-sealing sheet peels off only when the food has reached an adequately cooked state, an enough amount of steam is generated and, due to the steam, the temperature at the vent hole portion has reached the temperature at which the pressure sensitive adhesive peels off. Therefore, by stopping the operation of the microwave oven when the steam has burst, there is no possibility of overheating the food.
  • the packaged food of the present invention is produced by enclosing food containing water or an aqueous solution in the container for packaging food of the present invention, the container for packaging food having, on one side thereof, a surface portion made of plastic sheet, at least one vent hole being formed in the vicinity of the center of the surface portion, the vent hole being sealed by an adhesive hole-sealing sheet whose vertical peeling strength is no less than 1 N/cm in the temperature range of 40° C. or lower and is no higher than 0.1 N/cm at the temperature range of 80° C. or higher.
  • the hole-sealing sheet thereof automatically peels off after the food has been sufficiently heated.
  • the present invention achieves an excellent effect that adequately cooked food can be easily obtained.
