Abstract

A package for high pressure treatment of foods and a method for treating foods at a high pressure, both being able to easily determine whether the foods accommodated in the package have been subjected to a high pressure treatment or not. The package for high pressure treatment includes a package body for accommodating articles to be treated at a high pressure, and an irreversible pressure-sensitive marker disposed on the package body at a position capable of being seen from the exterior of the package body and adapted to develop color when pressurized.

Claims

1. A package for high pressure treatment, the package accommodating articles in the interior thereof for subjecting the articles to a high pressure treatment, the package comprising:

a package body accommodating the articles; and

an irreversible pressure-sensitive marker disposed on said package body at a position capable of being seen from the exterior of said package body and adapted to develop color upon being pressurized.

2. The package for high pressure treatment according to claim 1, wherein said irreversible pressure-sensitive marker includes a base member having an installation surface, microcapsules disposed dispersedly on said installation surface of said base member and with pigment sealed therein, and a transparent film formed on said installation surface, said microcapsules having a function of being destroyed and developing color upon being pressurized.

3. The package for high pressure treatment according to claim 1, wherein said irreversible pressure-sensitive marker includes a base member, and a print material formed on said base member by printing and containing microcapsules with pigment sealed therein, said microcapsules having a function of being destroyed and developing color upon being pressurized.

4. The package for high pressure treatment according to claim 1, wherein said package body includes a flanged container having a flange portion, and a top film bonded to said flange portion to maintain the articles accommodated within said flanged container in a sealed condition, and said irreversible pressure-sensitive marker is disposed on an outer surface of said flanged container or at a bonded portion of said top film.

5. The package for high pressure treatment according to claim 1, wherein said package body includes a portion composed of a rigid material and having an installation surface, and said irreversible pressure-sensitive marker includes microcapsules disposed dispersedly on said installation surface of said package body and with pigment sealed therein and also includes a transparent film formed on said installation surface, said microcapsules having a function of being destroyed and developing color upon being pressurized.

6. The package for high pressure treatment according to claim 1, wherein said package body includes a portion composed of a rigid material and having an installation surface, and said irreversible pressure-sensitive marker comprises a print material formed on said installation surface of said package body by printing and containing microcapsules with pigment sealed therein, said microcapsules having a function of being destroyed and developing color upon being pressurized.

7. The package for high pressure treatment according to claim 5, wherein said package body includes a flanged container having a flange portion and also includes a top film bonded to said flange portion to maintain the articles accommodated within said flanged container in a sealed state, said flange portion being composed of a rigid material and having said installation surface.

8. The package for high pressure treatment according to claim 1, further comprising an irreversible temperature-sensitive marker provided on said package body and adapted to develop color at a heat treatment temperature.

9. The package for high pressure treatment according to claim 1, wherein said package body accommodates foods.

10. A method for treating foods at a high pressure, comprising:

accommodating foods within said package body of the package for high pressure treatment described in claim 1; and

subjecting the package for high pressure treatment to a high pressure treatment in the accommodated state of the foods.

11. A method for treating foods at a high pressure, comprising:

accommodating foods within said package body of the package for high pressure treatment described in claim 8; and

subjecting the package for high pressure treatment to both high pressure treatment and heat treatment in the accommodated state of the foods.

12. The package for high pressure treatment according to claim 6, wherein said package body includes a flanged container having a flange portion and also includes a top film bonded to said flange portion to maintain the articles accommodated within said flanged container in a sealed state, said flange portion being composed of a rigid material and having said installation surface.
