Abstract

PROBLEM TO BE SOLVED: To provide a container for a microwave oven preventing the flow-out of contents due to the falling of a pouch and facilitating the taking out of the pouch from the microwave oven by heating the pouch packed with fluid contents and sealed in a leaning state by the microwave oven. SOLUTION: The pouch 1 packed with the fluid contents transmitting microwaves and provided with an unsealing notch 2 at an upper tip part is housed in a heat-resistant synthetic resin cartridge 5 which is stacked with a flat-plate screen tool on its rear surface and can be used repeatedly. The folding pieces 8 and 8 of this screen tool are stand-folded and engaged by a holding piece 9 to assemble-form a screen tool 13. Then, perforations for forming an opening part are removed, the notch 2 of the pouch 1 is unsealed and then the pouch 1 is heated within the microwave oven in a leaning state.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave oven container for heating a sealed pouch filled with fluid contents such as fluid foods in a microwave oven.

[0002]

2. Description of the Related Art Fluid foods such as curries and sauces are usually packed in aluminum retort pouches, sealed, and heat-sterilized and stored in a paper outer box for sale. To prevent the passage of microwaves, it is necessary to heat the pouch in hot water or remove the pouch from the outer box, transfer the contents to a dish or the like, and then heat with a microwave oven. To remedy this defect, a retort pouch that passes microwaves has recently been developed, and heating in a microwave oven is considered. However, if the temperature inside the pouch increases and the internal pressure increases, the pouch may burst. For this reason, it is necessary to provide an opening portion in the pouch and heat while removing steam.

[0003]

However, when a microwave-heated retort pouch is heated in a microwave oven as described above, the pouch taken out of the outer box is easily deformed and stands alone in the microwave oven. If the pouch is heated, it may be difficult to hold the liquid contents, and if it lays down during heating, the fluid contents may spill out of the steam vent opening. There are defects such as

[0004] In view of these circumstances, the present invention enables a retort pouch such as a retort food product to be leaned and held in a microwave oven so that the contents can be heated without spilling out, and the take-out operation can be easily performed by hand. It is an object of the present invention to provide a microwave oven container for retorted foods and the like.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a pouch filled with flowable contents through which microwaves are passed and having an opening notch on one side of an upper end; It is characterized by comprising a combination with a cartridge made of a heat-resistant synthetic resin in which an opening forming perforation is provided in opposition, and a flat screen tool having a bent piece that can be raised and lowered on the back surface is provided. It is more preferable that the plate-shaped partitioning tool is provided with a cut-and-raised holding piece for securely assembling and holding the partitioning tool by engaging when the bent piece is raised. It is preferable to form a transparent window so that a label or the like indicating the type or the like of the pouch stored therein can be seen through.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the accompanying drawings. For example, microwaves formed by laminating three films of nylon, ethylene-vinyl acetate copolymer, and unstretched polypropylene, respectively, will be described. The pouch 1 to be passed is filled with fluid contents such as curry and sauce,
It is sealed and heat-sterilized and stored, and has an opening notch 2 formed on one side of the upper end thereof. A paper box-shaped container 3 for sale
Is housed inside.

A flat box-shaped cartridge made of a heat-resistant synthetic resin having an opening forming perforation 4 at one side of a portion of the pouch 1 facing the opening notch 2 is provided on the back of the cartridge. The heat-resistant partitioning tool 6 in a shape is fixed in a polymerized state.

The partitioning tool 6 has a central joint 7 bonded to the cartridge 5, outwardly undulating bent pieces 8 provided on both sides of the joint 7, and a fold from the joint 7. A cut groove 10 is formed at the bent portion of the bent piece 8.8 in the cut and raised piece 9. 10 is provided, and the bent piece 8 and the holding piece 9 are arranged in a plate shape on the back surface of the cartridge 5 together with the joint portion 7 when carrying the pouch 1 and the pouch 1 can be inserted into the upper end of the cartridge 5. An opening or an opening / closing opening 11 is provided, and a transparent window 12 through which a label or the like indicating the contents of the pouch 1 can be seen is formed on the surface of the cartridge 5.

Since the present invention is constructed as in the above embodiment, when the pouch is heated by a microwave oven, the pouch 1 in the box-shaped container 3 is taken out, and the perforation 4 forming the opening is cut out and removed. The opening notch 2 is accommodated in the cartridge 5 through the opening 11 and the opening notch 2 is opened. Then, the bending pieces 8.8 of the flat screen tool 6 of the cartridge 5 are raised and bent, and the holding piece 9 is cut and raised. The notches 10 and 10 are engaged with the bent pieces 8 and 8 to assemble and form the partition 13, and the cartridge 5 is placed and held in the microwave oven by the partition 13 and heated. The heated pouch 1 is taken out while being stored in the cartridge 5 and the flowable contents are transferred from the opening notch 2 to a dish or the like.

Accordingly, by selling one cartridge in combination with each sale of one or a plurality of box-shaped containers 3,
The pouch 1 that has lost its shape and easily leaks its contents can be smoothly and reliably heated in a microwave oven, can prevent burns due to the operation of taking out the heated pouch 1 and its contents, and can also prevent the transparent window 12 of the cartridge 5 from being burned. Can see through the type of the contents of the heated pouch 1 and the like.
In addition, it is preferable to form bent folds in the bent portions of the bent pieces 8 of the partitioning tool 6 and the bent portions of the holding pieces 9 respectively.

[0011]

According to the present invention, a pouch which is filled with a fluid content such as a fluid food or the like and is easily deformed through a microwave and which is easily deformed is housed in a heat-resistant synthetic resin cartridge to assemble and form a flat screen tool. The screen is heated by supporting it in the microwave oven in a leaning state, so that the easily deformable pouch can be heated smoothly and reliably in a short time while preventing the contents from flowing out due to its lodging. The subsequent removal of the pouch from the microwave oven and the transfer of the contents to a dish, etc., can be performed safely without burns by gripping and operating the cartridge made of heat-resistant synthetic resin. Can do well.

Moreover, the partitioning tool of the heat-resistant synthetic resin cartridge of the present invention is formed in a flat plate on the back surface, has a compact structure, is easy to carry and transport, and can be quickly and easily assembled to the partitioning tool. In addition, since the same pouch can be subsequently used repeatedly and heated, microwave heating of this kind of retort food can be performed economically and efficiently.

[0013] The partitioning tool of the present invention can easily and easily assemble the bent piece and the cut-up piece into the partitioning tool, and the cutting groove of the holding piece engages the bent piece to lean the cartridge. The state can be reliably maintained stably.

Further, according to the present invention, the cartridge is provided with a transparent window on its surface so that the type of the pouch inside can be seen through a label or the like, so that the pouch to be heated can be easily recognized.
