Next, an embodiment of the present invention will be described.
The moisture permeable and waterproof sheet mounting structure of the present invention has an upper opening of a container in which ingredients are placed for cooking or vacuum cooling of ingredients (including food), steam cooling for cooling after cooking, or storage or transportation. It is a structure for closing with a moisture-permeable waterproof sheet.

  The moisture-permeable and waterproof sheet is formed of a moisture-permeable and waterproof material, and is usually formed of a thin material having flexibility. The moisture-permeable and waterproof material refers to a material having a property of allowing vapor (gas) to pass but not water (liquid). As such a moisture-permeable and waterproof material, a material having many very small holes or a material in which such a microporous film is bonded to a cloth can be used. Alternatively, a non-porous material that does not allow water droplets to pass therethrough but allows water vapor to move, or a coating-type material that performs a strong water-repellent treatment on a high-density fabric can also be used.

  As such a moisture-permeable and waterproof material, for example, Gore-Tex (registered trademark) or a non-woven fabric formed by polymerizing a plurality of sheets having different eyes is used, but is not limited thereto. The moisture-permeable waterproof sheet may be disposable especially in the case of a nonwoven fabric or the like. Normally, the moisture permeable waterproof sheet is entirely formed of a moisture permeable waterproof material, but in some cases, a material other than the moisture permeable waterproof material may be used for a part of the sheet. Even in that case, the moisture-permeable and waterproof material is disposed so as to be exposed in the opening of the presser frame described later.

  The shape of the container is not particularly limited. For example, the container is formed in a substantially rectangular box shape opened only upward or a substantially circular bottomed cylindrical shape. Further, it is preferable that a flange portion is formed at the upper end portion of the container so as to extend outward in the radial direction. A so-called hotel pan can be used as such a container. In this case, commercially available hotel pans, especially hotel pans already owned by the user can be used as they are. As is well known, the hotel pan has a substantially rectangular bottomed box shape, and the upper end portion is horizontally extended slightly outward and integrally formed with a brim portion. In general, hotel pans are made of stainless steel and have a standardized size. However, in some cases, a container having an arbitrary shape and size formed of other metals or synthetic resins can be used.

  After the food is stored in the container, the container is provided with the moisture permeable waterproof sheet stretched on the upper opening, and the upper opening is completely closed. Thereby, liquid and solid cannot pass through the inside and outside of the container, but only vapor can pass. Usually, the upper opening of the container is covered with a single moisture-permeable waterproof sheet. Therefore, the moisture-permeable waterproof sheet is formed larger than the upper opening of the container, and is typically formed to have an outer shape of the brim portion or slightly larger than that.

  The moisture permeable waterproof sheet is preferably attached to the container via a presser frame. The presser frame of the present embodiment is about the size of the upper opening of the container, and the outer peripheral portion is provided with the outer end portion of the moisture permeable waterproof sheet sandwiched between the upper end portion (collar portion) of the container. At this time, it is preferable to fit the mounting portion provided on the outer peripheral portion of the presser frame so as to overlap the upper end portion (head portion) of the container.

  An appropriate opening is formed through the presser frame. For example, in the case of a container made of hotel bread, the presser frame has the mounting portion having a substantially rectangular frame shape, and the substantially rectangular hole at the center of the mounting portion is the opening. The presser frame may be provided with an appropriate partition piece across the opening. For example, a horizontal plate-like partition piece can be provided at one place in the center of the opening, or at two places that divide the substantially rectangular opening into three equal parts. In any case, in a state where the upper opening of the container is closed with the moisture permeable waterproof sheet with the presser frame, the moisture permeable waterproof material is exposed from the opening of the presser frame.

  In order to securely hold the moisture-permeable waterproof sheet to the container, it is desirable to provide a holding means for detachably fixing the presser frame to the container. As this holding means, various configurations can be adopted, but a snap lock as a fastener is preferable. This pachinko tablet has a configuration as is well known. Explaining just in case, the snap lock is composed of a main body portion and a locking portion, one of which is provided on the presser frame and the other is provided on the container. The main body portion includes a hook and a lever that can be rotated around the pin, and can be engaged with the locking portion by pushing the lever down around the pin in a state where the hook is hooked on the locking portion. On the other hand, the engagement with the locking portion can be released by pushing the lever up around the pin.

  In the case where the main body portion of the snap lock is provided on the presser frame, the collar portion of the container can be used as the locking portion provided on the container. In this case, in a state where the presser frame is fitted in the upper opening of the container, the hook of the snap lock is hooked on the brim portion and the lever is pushed down. In the case of such a configuration, there is no need to bother to provide a locking portion on the container, and for example, a commercially available hotel pan can be used as it is.

  The holding means may be a belt-like material (belt) wound around a container provided with a presser frame via a sheet. Specifically, it is bent so that it can be wound along a container provided with a presser frame via a sheet, and the open and closed ends are provided with a main body part and a locking part of a snap lock at both open ends. It is a stainless steel belt-like material in which the parts can be engaged with each other. Alternatively, it may be a belt-shaped material made of cloth and its both open ends can be attached and detached with a hook-and-loop fastener, or simply a ring-shaped rubber band. The attachment position of such a strip-like material to the container is not particularly limited, but it is preferable to place a snap lock at a position corresponding to the partition piece of the presser frame and wind it around the container. The holding means may be a ring belt using an elastic material such as rubber. Further, the holding means may be a clip that detachably sandwiches the upper end portion (head portion) of the container and the outer end portion of the presser frame via a moisture-permeable waterproof sheet. Further, the holding means can be configured to detachably fix the presser frame to the container by its own weight or magnetic force.

  Food is contained in the container, and the upper opening is closed with the moisture-permeable waterproof sheet as described above. And the foodstuff in a container is steamed, vacuum-cooled, or steam-cooled. There are no particular restrictions on the type of food, but it is particularly suitable for liquid foods having at least a portion of liquid, such as curry roux, ramen soup, and boiled food. Since the upper opening of the container is closed with a moisture-permeable waterproof sheet, there is no risk that food in the container will spill outside, and conversely, other than steam will be prevented from entering from the outside of the container.

  Therefore, especially during storage, dust and foreign matter are prevented from being mixed, and during transportation, dust and foreign matter are not prevented from being mixed, and the contents are not spilled. And at the time of cooking, it is prevented that the condensed water from an upper shelf, an upper container, etc. falls in a foodstuff. Moreover, even when the food is boiled during vacuum cooling or evacuation for steaming, spilling and scattering are prevented. In this way, a series of operations such as steaming and subsequent vacuum cooling and storage can be performed with the container covered with the moisture-permeable waterproof sheet.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.
FIGS. 1 to 4 are views showing Example 1 of the moisture-permeable and waterproof sheet mounting structure of the present invention, FIG. 1 is an exploded perspective view, FIG. 2 is a perspective view showing a use state, and FIG. III-III sectional view, FIG. 4 is a IV-IV sectional view in FIG.

  The moisture permeable waterproof sheet mounting structure of the present embodiment is moisture permeable and waterproof to the upper opening of the container 2 containing the food 1 before the food (including food) 1 is cooked, vacuum-cooled or steam-cooled. This is a structure for covering with the conductive sheet 3. The effect by covering the upper opening of the container 2 with the moisture-permeable waterproof sheet 3 is particularly effective in the case of a liquid food material. Therefore, in this embodiment, the description will be made assuming that the food material to be put in the container is the liquid food material 1. However, it can be similarly applied to other foods. The liquid food material 1 includes, for example, curry roux, ramen soup, boiled foods, and the like.

  The container 2 of the present embodiment is a hotel pan. That is, the container 2 is formed in a substantially rectangular bottomed box shape opened only upward. A flange 4 is formed at the upper end of the container 2. The flange portion 4 is formed to extend horizontally from the upper end portion of the container 2 outward in the radial direction. The outer end portion is provided with a falling portion 5 that slightly extends downward. The flange portion 4 having the falling portion 5 is continuously formed along the circumferential direction at the upper end portion of the container 2, and the outer shape thereof is substantially rectangular in a plan view. The container 2 may be made of a synthetic resin or the like, but is made of a metal such as stainless steel in the present embodiment, and is manufactured by being integrally formed with the flange portion 4 or the like by press molding. As such a container 2, a commercially available hotel pan, particularly a hotel pan already owned by the user can be used.

  After the liquid food 1 is put in the container 2, the upper opening is closed with the moisture-permeable waterproof sheet 3 in the mounting structure of this embodiment. The moisture permeable waterproof sheet 3 is formed of a moisture permeable waterproof material. As the moisture permeable and waterproof material, various materials having a property of passing steam but not water are used. In this embodiment, a non-woven fabric formed by polymerizing a plurality of sheets having different eyes is used, but it goes without saying that other materials can also be used.

  The moisture permeable waterproof sheet 3 of the present embodiment is entirely formed of the nonwoven fabric. That is, the moisture-permeable waterproof sheet 3 of the present embodiment is a non-woven fabric formed in a desired size and has soft flexibility. Although the size and shape of the moisture-permeable waterproof sheet 3 are set as appropriate, in this embodiment, the moisture-permeable waterproof sheet 3 is formed in a substantially rectangular shape that is slightly larger than the outer shape of the flange portion 4 of the container 2.

  The moisture permeable waterproof sheet 3 is held by the container 2 by the presser frame 6 in a state where the upper opening of the container 2 is sealed. The presser frame 6 of the present embodiment is formed of stainless steel or the like and has a substantially rectangular shape. The outer peripheral portion of the presser frame 6 is overlapped with the flange portion 4 of the container 2 to be a mounting portion 7 to be fitted. Specifically, the substantially rectangular presser frame 6 has an outer peripheral portion formed in a substantially U-shaped section facing downward. That is, the mounting portion 7 includes a horizontal piece 8 arranged substantially horizontally, an outer hanging piece 9 slightly extending downward on the outer peripheral side of the horizontal piece 8, and slightly downward on the inner peripheral side of the horizontal piece 8. It is composed of an extending internal hanging piece 10.

  As described above, the presser frame 6 is held by the mounting portion 7 formed on the outer peripheral portion being fitted into the upper end portion of the container 2. At that time, the horizontal piece 8 of the mounting portion 7 is superimposed on the flange portion 4 of the container 2. Then, the outer hanging piece 9 of the mounting portion 7 is overlapped with the falling portion 5 of the collar portion 4 and / or the inner hanging piece 10 of the mounting portion 7 is disposed on the inner peripheral portion of the collar portion 4. In this way, the presser frame 6 is fitted into the upper end portion of the container 2 and positioned. This inset condition can be tight or loose.

  An appropriate opening 11 is formed in the presser frame 6 inside the mounting portion 7 having a substantially rectangular frame shape. In the present embodiment, the mounting portion 7 having a substantially rectangular frame shape is provided with horizontal plate-like partition pieces 12 and 12 extending in the front-rear direction at two locations that divide the inner region into approximately three equal parts. It is done. Thereby, the substantially rectangular opening parts 11 and 11 are arrange | positioned at the left and right of each partition piece 12, respectively.

  At the both ends in the front-rear direction of each partition piece 12 of the presser frame 6, snap locks 13 and 13 are provided, respectively. In the present embodiment, a support material (not shown) of the snap lock 13 is fixed to the upper surface of the partition piece 12, and a lever 15 is rotatably provided around a first pin 14 provided on the support material. A hook 17 is provided in the middle of the lever 15 so as to be rotatable around the second pin 16. The first pin 14 and the second pin 16 are arranged along the left-right direction. Each hook 17 can be arranged such that its tip end faces outward in the front-rear direction, and the tip portion 18 is bent in a substantially U shape. On the other hand, each lever 15 can be arranged to extend inward in the front-rear direction in the direction opposite to the tip of the hook 17.

  In order to close the upper opening of the container 2 containing the liquid food material 1 with the moisture-permeable waterproof sheet 3, the following procedure is performed. That is, the presser frame 6 is attached to the upper end portion of the container 2 in a state where the moisture-permeable waterproof sheet 3 is disposed so as to cover the upper opening of the container 2. Thereby, the outer edge part of the moisture-permeable waterproof sheet 3 is pinched | interposed and hold | maintained between the collar part 4 of the container 2, and the mounting part 7 of the presser frame 6 over the circumferential direction whole region. In this state, after hooking the hook 17 of the snap lock 13 on the falling part 5 of the flange part 4, the lever 15 may be pushed down. Thereby, the presser frame 6 is fixed to the container 2, and the moisture-permeable waterproof sheet 3 is held by the container 2. Since the holding frame 6 has a relatively large opening 11, the moisture-permeable waterproof sheet 3 is exposed from the opening 11.

  As described above, the liquid food material 1 in the container 2 whose upper opening is closed with the moisture permeable waterproof sheet 3 is cooked with a steamer, vacuum cooled with a vacuum cooler, or steamed cooler, for example. And vacuum-cooled after cooking. As a steamer or steaming cooling, what is shown by Unexamined-Japanese-Patent No. 2005-65797 can be used, for example, and what is shown by Unexamined-Japanese-Patent No. 2004-170060 can be used as a vacuum cooler, for example. However, the configuration of the steamer, the vacuum cooler, or the steam cooler is not limited to these, and various conventionally known devices can be used.

  Typically, the vacuum cooler is provided with a pressure-reducing means, a pressure-reducing means, and a control means for controlling each means in a sealable processing tank. On the other hand, the steaming machine and the steaming cooler are provided with a pressure-reducing means, a pressure-reducing means, a steam supplying means, a discharging means, and a control means for controlling these means in a sealable processing tank.

  Here, the decompression means is means for decompressing the inside of the processing tank by sucking and discharging the air in the processing tank to the outside. This decompression means is configured by providing a vacuum pump, a steam ejector, a water ejector, or the like in a vacuum line connected to the treatment tank. The return pressure means is means for introducing outside air into the treatment tank under reduced pressure and restoring the pressure in the treatment tank. The return pressure means is configured by providing an opening / closing valve, a filter, and the like in a return pressure line connected to the processing tank. The steam supply means is means for supplying steam into the treatment tank and is configured to include a boiler. At this time, it is preferable to generate steam from soft water or pure water in a secondary boiler (reboiler) using steam from a general primary boiler as a heat source, and supply this clean steam into the treatment tank. The discharge means is means for discharging the steam in the treatment tank and its condensed water to the outside. This discharge means is configured by an openable / closable drainage line or a steaming line connected to the treatment tank.

  What is necessary is just to supply the vapor | steam in the processing tank, putting the container 2 which put the liquid foodstuff 1 in the processing tank of a steamer for heating cooking, such as a boiled food. The upper opening of the container 2 in which the liquid food material 1 is placed is closed with a moisture permeable waterproof sheet 3, which is breathable. Therefore, cooking of the food material 1 by steam is performed quickly through the moisture-permeable waterproof sheet 3. Moreover, since the moisture-permeable waterproof sheet 3 has waterproof properties, it is possible to prevent condensed water generated on the upper shelf, the outer surface of the upper container, and the like from falling into the food material 1 and being mixed therein.

  In order to vacuum-cool the warm liquid food material 1, put the container 2 containing the liquid food material 1 in the processing tank of the vacuum cooler, evacuate the air in the processing tank to the outside, and depressurize the inside of the processing tank. That's fine. The upper opening of the container 2 in which the liquid food material 1 is placed is closed with a moisture permeable waterproof sheet 3, which is breathable. Accordingly, the pressure in the container 2 can be reduced through the moisture-permeable waterproof sheet 3, and the steam from the food 1 can be led out of the container 2. Therefore, the vacuum cooling of the food material 1 is performed quickly. Moreover, even if the liquid food material 1 boils due to the reduced pressure in the treatment tank, the upper opening of the container 2 is covered with the moisture-permeable waterproof sheet 3, so that the food material 1 spills out of the container 2 or scatters. There is no fear of doing it. And since the moisture-permeable waterproof sheet 3 is hold | maintained at the container 2 with the presser frame 6, even if the vapor | steam which generate | occur | produces from the foodstuff 1 during vacuum cooling prevents that a moisture-permeable waterproof sheet 3 remove | deviates from a container. The

  By the way, when cooking with a steamer, first, the air in the processing tank is sucked and discharged to the outside. At this time, the pressure in the processing tank may cause the liquid food material 1 to boil. However, even in this case, since the upper opening of the container 2 containing the liquid food material 1 is closed by the moisture-permeable waterproof sheet 3, the food material 1 is prevented from being blown out or scattered.

  In order to perform steaming and subsequent vacuum cooling in one processing tank, after putting the container 2 containing the liquid food material 1 into the processing tank of the steaming cooler and performing the same processing as the steaming by the steaming machine. The same process as the vacuum cooling by the vacuum cooler may be performed. Here, regardless of the steam cooler, first, after cooking with a steamer, the container 2 may be moved to a vacuum cooler and vacuum cooled with a vacuum cooler. In order to easily move from the steamer to the vacuum cooler, the container containing the liquid food material 1 is put in and out of the treatment tank while being placed on the wagon, and also moved from the steamer to the vacuum cooler. Good.

  Furthermore, if the container 2 in which the liquid food material 1 is put is covered with the moisture permeable waterproof sheet 3, there is a merit at the time of storage and transportation. That is, at the time of storage, mixing of dust or foreign matter is prevented. Further, during transportation, not only dust and foreign matters are prevented from being mixed, but even if the liquid food material 1 is put to the very bottom of the container 2, there is no risk of spilling the contents. Further, for example, a series of operations such as the above-described steaming by the steamer, the subsequent vacuum cooling by the vacuum cooler, and the movement between them, and the storage after the vacuum cooling are once covered with the moisture-permeable waterproof sheet on the container 2. This can be done without opening the lid.

  As described above, the upper opening of the container 2 in which the liquid food material 1 is placed is closed with the moisture-permeable waterproof sheet 3 so that steaming, vacuum cooling, storage, or transportation can be performed in a sanitary manner. Can be done with good yield. Then, after the operation, the lever 15 of the snap lock 13 is pushed upward around the first pin 14 to release the engagement of the hook 17 with the collar portion 4, so that the presser frame 6 and the moisture-permeable and waterproofing from the container 2 are released. The property sheet 3 can be removed. Since the moisture-permeable waterproof sheet 3 of this embodiment is disposable, post-processing is also easy.

  FIGS. 5 and 6 are views showing Embodiment 2 of the moisture-permeable waterproof sheet mounting structure of the present invention. FIG. 5 is a perspective view of the holding means 19 for fixing the presser frame 6 to the container 2, and FIG. It is a perspective view which shows the attachment state to the container 2 of the frame 6. FIG. The moisture-permeable and waterproof sheet mounting structure of Example 2 and the presser frame 6 and moisture-permeable and waterproof sheet 3 used therefor are substantially the same as those of Example 1. Therefore, in the following description, the differences between the two will be mainly described, and corresponding portions will be described with the same reference numerals.

  In the first embodiment, the snap lock 13 as a holding means for removably fixing the presser frame 6 to the container 2 is provided on the presser frame 6 itself. However, in the second embodiment, the presser frame 6 itself is not provided with the snap lock 13. That is, the presser frame 6 of the second embodiment is configured by removing the four snap locks 13 from the presser frame 6 of the first embodiment. Instead, in the second embodiment, in order to securely fix the presser frame 6 held in the upper opening of the container 2 to the container 2 through the moisture permeable waterproof sheet 3, the holding means 19 is shown in FIG. The strip 20 shown is used.

  The belt-like material 20 of the present embodiment is configured by bending a metal material such as stainless steel. That is, the elongate metal strip 20 is bent so as to be wound around the container 2 provided with the presser frame 6 with the moisture-permeable and waterproof sheet 3 interposed therebetween. Specifically, it is bent and formed into a substantially U-shape opening upward, and the open both end pieces 21 and 22 are further bent in the direction in which they are close to each other.
