Description

[Detailed Description of the Invention] This invention relates to an improvement in a tray that supports flexible food packaging during sterilization.

Currently, a large number of flexible packaging bodies (hereinafter simply referred to as packaging bodies or retort pouches) are on sale especially for a large number of foods, which are packaged with a heat-resistant resin film or a material made by laminating these with aluminum foil. When sterilizing retort pouches with hot water, conventionally, as shown in FIG.
a and 1b to prevent the packages from overlapping each other even if they move during sterilization, and small holes 1e for hot water and steam flow during sterilization are provided in the peripheral wall 1c and bottom wall 1d, respectively. A tray 1 having a depth slightly greater than the thickness of the wrapped package 2 is used.

Retort pouches 2 are placed in each compartment of the tray 1 as shown in the figure, and the pouches are stacked in multiple stages and introduced into a sterilizer (not shown) for sterilization.

In recent years, it has been attempted to improve the sterilization efficiency of stored foods by rotating this multi-tiered tray in a sterilizer. This caused the packages to flow and the individual packages to move within the compartments, resulting in wrinkles in the packages and, in extreme cases, serious defects such as the occurrence of fatal pinballs due to the wrinkles.

This invention was made to solve such problems, and one embodiment of the invention will be described below with reference to FIGS. 2 and 3.

The tray 10 of this invention has partition walls 10 in the vertical and horizontal directions.
a, 10b, and having communication holes 10e in the peripheral wall 10c and the like are similar. However, the arrangement spacing between one or both of the partition walls 10a, 10b is determined to be slightly smaller than the length between opposing edges of the package 2 to be accommodated, and the partition plate 11 which has no bottom wall and divides the depth of the tray into approximately two halves is provided.

When the packages 2 are arranged on the tray 10 as shown in FIG. 3 and stacked in multiple stages, each package 2 is stacked on the tray 10 as shown in FIG.
is housed in a partition chamber formed by partition walls and between partition plates 11 between upper and lower trays 10, and at least one opposing edge of the package 2 is located between partition walls 10a and 10b of vertically adjacent trays 10. It is fixedly supported by being sandwiched between them. In the figure, reference numeral 12 denotes a silicone sheet attached to the portion that abuts the edge of the package, thereby preventing damage to the package 2.

In this invention, when the packages are arranged on trays and sterilized as described above, at least the edges of the packages are sandwiched and supported between the trays, so that each package is securely fixed in the partitioned room, and the above-mentioned Even during rotation during sterilization, there is no movement of the package within the compartment, and therefore the occurrence of pinballs due to wrinkles in the package described above can be prevented.
