Description

[Detailed description of the invention] This invention is a flat, flexible container whose innermost layer or a portion thereof is composed of a heat-sealable film, and which is filled with food or other objects to be sterilized and sealed. Flexible packaging at 100℃
The present invention relates to an improvement in a transport container for a flexible package used for continuous sterilization at a sterilization temperature above and a pressure of 1 atm or above.

When sterilizing a flexible package (flexible pouch) using a continuous sterilizer, the flexible package is not a rigid body like a canned product, but is flexible, has weak mechanical strength, and cannot be bent or bent.
Pinholes and broken bags may occur due to wrinkles, etc.

Therefore, if the flexible package is transported as it is for sterilization or the like, it is likely to be damaged as described above, and therefore, it is necessary to use a container to protect the flexible package when handling it.

Furthermore, the container that protects the flexible packaging is susceptible to damage when the container housing the flexible packaging rotates during heat sterilization and cooling processes of the flexible packaging in the pressure chamber of the continuous sterilizer. As the flexible packaging moves up and down inside the container, problems such as bending and wrinkles occur, and friction between the container surface and the flexible packaging causes scratches on the outside of the packaging. Therefore, it is required that the container is always kept horizontal during transportation.

In response to the above-mentioned demands, it is used in continuous sterilizers that continuously feed a flexible package from atmospheric pressure into the pressure chamber of the sterilizer, perform heat sterilization and cooling, and then discharge it to the outside. Considering that when an airtight rotary valve is used as a mechanism, a cylindrical body like a canister is easy to handle, both ends of the outer periphery are cylindrical so that containers stacked in several tiers can be kept horizontal at all times. The inventors of this invention had previously proposed a flexible packaging carrier that can be transported by using a flexible package, and have used it with many successes.

This invention further improves the flexible package carrier,
In particular, we provide a storage container for flexible packaging that allows for accurate stacking, prevents stacked containers from collapsing, and allows for easy stacking of containers and disassembly of stacked containers.
The object is to provide this by improving the structure of both ends.

An embodiment of this invention will be described below with reference to the drawings together with a conveyor.

As shown in FIGS. 1 and 2, this heatable packaging container 1 has a dish-like rectangular parallelepiped shape, is partitioned by a frame 3, and stores a plurality of flat flexible packaging materials 4 horizontally. The container body 2 has a height sufficient to create a space above the package 4 housed therein, and has a large number of ventilation holes 2a in the bottom wall, side walls, and frame 3.

This main body 2 has outward channel members 5 fixed to the outer surfaces of both ends, and has flat upper and lower protruding plates 6 and 7 protruding from the upper and lower surfaces of the container main body 2, respectively. In addition to providing protrusions 8 formed into truncated conical shapes, holes 9 of the same number as the protrusions 8 are formed in the lower protrusion plate 7 at positions corresponding to the protrusions 8, and are of a size and shape such that the protrusions 8 are removably fitted therein. This is what I did.

In this invention, the upper and lower protruding plates 6, 7 may not be provided over the entire length of both end sides of the container body 2, but may be provided only on a portion of the end sides.

Furthermore, the shapes and sizes of the projections 8 and holes 9 can be changed as appropriate.

The carrier 21 into which the flexible packaging storage container 1 is inserted is provided with an outer container 10 for storing the container 1, as shown in FIGS. 3, 4, and 5.

The outer container 10 has an opening at least on the front surface, so that it can removably accommodate the flexible packaging containers 1 stacked one above the other in multiple stages, and has an air permeable bottom and a weight 11 on the bottom. It is fixed.

A restraining plate 12 is arranged on the outer container 10, and this restraining plate 1
2, a guide shaft 13 fixed to both ends slidably penetrates both end walls of the outer container 10 and extends below the bottom of the outer container 10;
An opening operation rod 14 is fixed to the lower end of the guide shaft 13, and the holding plate 12 is biased downward by a coil spring 15 whose lower end is supported by the operation rod 14 and whose upper end is supported by a step on the end wall of the outer container 2. This is supported on the wall soil at both ends of the outer container 10.

Shafts 16 fixed to both end walls of the outer container 10 are respectively supported by bearings 17, and the bearings 17 are fitted onto both cylindrical ends 18a of the cylindrical body 18.

At the center of the cylindrical body 18, there are two rod-like sections 18b having an arcuate cross section, and a large cutout section 18C.

In FIG. 5, 19 is a lower stopper provided on the rear surface of the bottom of the outer container 10, and 20 is an upper stopper provided on the holding plate 12.

Next, the use of the flexible package transport container constructed as described above will be explained.

First, the flexible packaging body 4 is accommodated in the container main body 2 of the flexible packaging body container 1, and the front housing containers 1 are stacked in multiple stages above and below.

In this case, by removably fitting the protrusion 8 of the lower storage container 1 into the hole 9 of the upper storage container 1, the storage containers 1 can be accurately stacked vertically and prevent them from collapsing. Furthermore, the package 4 is prevented from being unnecessarily displaced within the transport container 1.

Next, by pushing up the opening operation rod 14 of the transport tool against the spring 15, the stacked storage containers 1 are moved to the cylindrical body 18 while the holding plate 12 is raised via the guide shaft 13.
Fit the notch 18C into the outer container 10.

By releasing the push-up of the opening operation rod 14, the holding plate 12 is lowered by the restoring force of the spring 15, and the storage container 1 is pressed against the bottom of the outer container 10 and fixed.

In this state, while keeping the outer container 10 and the storage container 1 horizontal and transporting the carrier, the flexible package is sterilized by heating and pressure, and is cooled.

Thereafter, the holding plate 12 is raised by the opening operation rod 14, and the container 1 is taken out of the cylindrical body 18 from the outer container 10 through the notch 18C.

The hole 9 of the upper housing container 1 is removed from the protrusion 8 of the lower housing container 1, the housing containers 1 are separated one by one, and then the flexible package is taken out from the housing container 1.

As explained above, the transportation container of this invention has two container bodies.
Upper and lower protruding plates 6, 7 are formed outwardly at both ends of the upper and lower surfaces thereof, and holes 9 provided in the lower protruding plate 7 of the upper storage container are provided in the upper protruding plate 8 of the lower storage container. By fitting the protrusions 8, the containers are stacked up and down in multiple stages and inserted into the cylindrical body, and supported by a spring. This allows the containers to be stacked accurately and to prevent them from collapsing, making it possible to use a transport tool. When the storage containers are stored in a stacked state in the outer container 10, by pressing only the uppermost storage container downward, the storage containers can be held so that they do not fall out into the outer container 10 unnecessarily.

Further, since an outwardly facing U-shaped portion is formed by both end walls of the container body 20 and the upper and lower protruding plates 6 and 7, these portions can be used to stack containers or separate stacked containers. These operations can be easily automated by mechanical means, and the entire cylindrical shape can be simply rolled. This has the effect of improving processing efficiency and simplifying the structure of the front and rear devices.
