Description

  The present invention relates to a heated food container for packaging take-out lunch boxes, noodles, gratin and other foods, and more specifically, a container body with a lid that is covered with a lid on a container body filled with ingredients. The present invention relates to a container for heated food wound around a band seal.

  In stores such as convenience stores, bento packed with rice and prepared dishes, noodles such as yakisoba, gratin and other foods (hereinafter collectively referred to as “bento”) are packaged and sold in heated food containers. . In the heated food container, an opening is provided on the upper side, and the container body packed with food for lunch is combined with a lid body that covers the opening, and the endless band seal is wound in a tightly-contacted state. There is also a thing which prevented the cover from removing from the container body. And the label which displayed the brand name, the price, the raw material, the expiration date, and other merchandise information is affixed to the bottom of the container main body, the corner of the lid, or the bandage.

  Also, Patent Document 1 discloses a packaging container that can be heated in a microwave oven. This packaging container is characterized in that at least both peripheral side surface outer circumferences of the container body and the lid that are fitted are integrally covered with a band seal. The band seal is made of a synthetic resin film that is stretched in the width direction, and contracts in the width direction when heated. Therefore, even if irregularities are formed on the peripheral side surface portions of the container main body and the lid, the band seal is in close contact with the peripheral side surface portion so that the packaging cannot be unwound unless the band seal is cut.

  In addition, although the band seal disclosed in Patent Document 1 is wound around the peripheral side surface portion of the container main body and the lid body, there is also a band seal wound around the bottom and both side portions of the container main body and the top surface of the lid body. .

Japanese Utility Model Publication No. 5-10271

  In the food factory, the band seal is tightly surrounded by the lid-covered container body with the lid on the opening of the container body, and then lightly heated and contracted, thereby closely contacting the container body with the lid body. Wrapped in a state, the lid is shipped so that it does not come off the container body. In stores such as convenience stores, lunch boxes are sometimes reheated and sold.

  At this time, if the bandage is tightly wound around the container body with the lid, the heated bandage is contracted too much, and the container body with the lid is deformed into a constricted state. In particular, an inexpensive lunch box is easily deformed because the container for heated food is also formed into a thin wall with an inexpensive material.

  Therefore, by removing the band seal from the container body with the lid and heating, the container body with the lid can be prevented from being deformed.

  However, when the band seal is removed, the lid body is easily detached from the container main body while taking the lunch box home. Moreover, when the label which described the merchandise information is stuck on the bandage, it is not preferable to remove the bandage from the container body with a lid. Therefore, the removed band seal may be re-wound around the container body with a lid, but this is a troublesome operation.

  Then, this invention makes it a subject to provide the container for heated foods which did not deform | transform this container main body with a lid even if the container main body with a lid wound with the band seal was heated several times. .

  The container for heated food according to the present invention is for a heated food in which an endless band seal having heat shrinkability is wound around a container body with a lid that covers a container body filled with ingredients, and is heated a plurality of times. The band seal has a winding part and an extra, and the first part is heated, and the extra part is temporarily bonded, and the winding part contracts to surround the container body with a lid. Wrapped in a state of being in close contact with the second time, during the second heating, the excess temporary bonding is peeled off, the contracted winding part and the excess are contracted and wound in a state of being in close contact with the periphery of the container body with a lid It is a feature.

  According to this heated food container, the wrapping has a winding part and an extra part, and in a state where the extra part is temporarily bonded together in a food factory or the like, only the winding part surrounds the container body with a lid with a margin. By being heated for the first time, the wound portion contracts and winds in a state of being in close contact with the container body with a lid, and is shipped so that the lid does not come off the container body. At this time, the band seal is configured not to deform the wound container body into a constricted state by the first heating due to the contraction of the wound portion too much. Then, in the store, the extra temporary bonding is peeled off, and the second winding is performed in a state where the contracted winding part and the excess surround the container body with the lid with a margin, and the winding part and The excess shrinks and wraps in close contact with the container body with the lid. Since the winding part and the excess surround the container body with a lid, when the second heating is performed and the container body shrinks, the container body with the lid is in close contact with the container body so as not to be deformed. Wrap around.

  In the heated food container according to the present invention, it is preferable that the excess is temporarily bonded with a bonding force that is forcibly removed immediately before the second heating. According to this heated food container, the excess is temporarily bonded with a sticking force that is forcibly removed immediately before the second heating, so that the excess is temporarily bonded until the second heating. Is not peeled off, and is forcibly removed immediately before the second heating, so that the winding part and the excess surround the container body with a lid with a margin, and by the second heating, Wrap the lid with the lid so that it does not deform into a constricted state.

  In the heated food container according to the present invention, it is preferable that the excess is temporarily bonded at a plurality of locations. According to this container for heated foods, since the excess is temporarily bonded at a plurality of locations, each of the excess temporarily bonded is smaller than when temporarily bonded at one location. Can be easily peeled off.

  Further, in the heated food container according to the present invention, it is preferable that the backsides of the banding overlap each other and the whole or part of the backside is temporarily bonded. According to this heated food container, since the excess can be temporarily bonded by part coat or the like, the temporary bonding operation can be performed efficiently.

  Further, in the heated food container according to the present invention, it is preferable that the excess overlaps with the winding portion and the entire surface or a part thereof is temporarily bonded to the winding portion. According to the container for heated food, the extra portion is temporarily attached to the winding portion, so that the extra portion does not rise from the winding portion and can be prevented from being caught by surrounding objects. In addition, even if an extra back surface is not temporarily bonded together and only an excess and a winding part are temporarily bonded together, it can prevent a container main body with a lid from deform | transforming by heating several times.

  In the heated food container according to the present invention, it is preferable that the banding is wound around the container body with a lid so as to be in close contact with the bottom surface of the container body and the top surface of the lid body. According to the container for heated food, the band seal is wound around the container body with the lid by winding the band seal in close contact with the container body with the lid so that the band seal is joined to the bottom surface of the container body and the upper surface of the lid. The work can be facilitated, and the band seal wound in close contact can be made difficult to come off from the container body with the lid.

Even if the product information such as the product name and the expiration date is displayed on the wrapping, and the wrapping is wrapped around in a state of being in close contact with the container body with a lid, the second heating is performed in the present invention. Before the wrapping, the wrapping will surround the container body with a lid with sufficient margins, and the wrapping will be wound in close contact with the second heating, so the trouble of removing or wrapping the wrapping in the store, etc. Can be eliminated. Note that the product information is displayed on the bundling includes not only affixing a label on which the product information is printed but also printing the product information directly on the bundling.

  According to the present invention, the endless band seal has a wound part and an extra, and the first part is heated in a state where the extra is temporarily bonded, whereby the wound part shrinks and the container with the lid The main body is wound in a close contact state without being deformed, and the second heating is performed in a state where the excess temporary bonding is peeled off, so that the contracted winding portion and the excess are attached to the container body with the lid. Wraps in close contact without deformation. Therefore, when re-heating the lunch box in the store, it is possible to save the trouble of removing the band seal and rewinding, improving workability in the store and improving services such as not waiting for customers. Can be achieved.

  An embodiment of a heated food container according to the present invention will be described with reference to FIGS. In addition, illustration of a foodstuff is abbreviate | omitted in sectional drawing of FIG. 2 thru | or FIG.

  The container for heated food in the present embodiment is obtained by winding an endless band seal 20 having heat shrinkability around a container body 10 with a lid that covers a container body 11 filled with ingredients. 20 has a winding part 21 and an extra 22. The container body 11 is not limited to a tray shape as shown in the figure, but is a shape such as a mortar shape, but an opening is formed on the upper side.

  The lid 12 is formed in a shape in which the periphery is covered with the opening of the container body 11. That is, as shown in the figure, the opening of the container body 11 and the lid body 12 are fitted in an uneven shape, the container body 11 has an upward bowl shape, and the lid body 12 has a downward bowl shape. In addition, the case where the outer peripheral portion of the lid body 12 is covered so as to surround the outer peripheral portion of the container main body 11 is also included.

  The band seal 20 is wound so as to be joined to the bottom surface and both side surfaces of the container body 11 and the top surface of the lid body 12 so as to be easily wound around the container body 10 with lid body. Moreover, the band seal 20 wound in this way becomes difficult to remove from the container body 10 with a lid.

  And this banding 20 surrounds the container main body 10 with a lid with sufficient margin, shrinks when heated, and winds in a state of being in close contact with the container main body 10 with a lid. That is, when the heated food container is heated a plurality of times, for example, twice, the band seal 20 shrunk by being heated twice is in close contact without deforming the container body 10 with the lid. In order to be wound around, the band seal 20 is provided with a winding portion 21 and an extra portion 22. The part of the band seal 20 other than the extra 22 is the winding part 21.

  Specifically, the extra 22 is formed by temporarily bonding the band seal 20 with an adhesive force such as a weak seal that can be forcibly removed by hand. That is, the extra 22 is not peeled off as shown in FIGS. 1 and 2 until the first heating, and immediately before the second heating, the temporary bonding is performed as shown in FIG. It is forcibly removed by hand.

  The extra 22 is efficiently formed by, for example, part coating, where the back surfaces of the band seal 20 are overlapped and the entire or part of the back surface is temporarily bonded. Alternatively, the extra portion 22 overlaps with the winding portion 21, and the entire surface or a part of the overlapped portion is temporarily attached, so that the extra portion does not rise from the winding portion 21 and is not caught by surrounding objects. Has been. Furthermore, the back surfaces of the excess 22 may not be temporarily bonded together, and only the portion where the excess 22 and the winding portion 21 overlap may be temporarily bonded. In any case, the temporary bonding is formed at a plurality of two small places or three or more places so that they can be easily peeled off, but one place depending on the shrinking length or the extra 22 width. It may be temporarily bonded together.

  The band seal 20 on which the extra 22 is temporarily bonded surrounds the container body 11 with a lid with a margin as shown by the phantom line in FIG. The container body 10 with a lid is filled with food in a container body 11 in a food factory, and the lid 12 is put on the opening of the container body 11. Then, by the first heating in the food factory, the winding portion 21 contracts and winds in a state of being in close contact with the container body 10 with the lid as shown by the solid lines in FIGS.

  However, if the margin of the band seal 20 surrounding the container body 10 with the lid is too large, the winding portion 21 does not wind in a state of being in close contact with the container body 10 with the lid even if the first heating is performed. If the body 12 is likely to come off from the container body 11 and the margin is too small, the shrunk band seal 20 is deformed so that the container body 10 with a lid is constricted by the first heating. Therefore, the margin of the band seal 20 surrounding the container body 10 with the lid is such that the winding part 21 contracted by the first heating can be wound in a close contact state without deforming the container body 10 with the lid. Has been.

  In addition, during this first heating, a pressing plate (not shown) is placed on the band seal 20 that overlaps the lid 12. Since the bandage 20 of this part is harder to be heated than the bandage 20 of other parts, the shrinkage rate is small. Therefore, it is preferable that the extra 22 is positioned on the lid 12 so that the extra 22 is not easily contracted during the first heating, and a pressing plate is placed on the extra 22. However, the extra 22 may be located on the bottom side of the container body 11 in order to improve the appearance.

  In any case, product information is displayed on the portion where the band seal 20 is located on the lid 12. That is, a label 23 describing product information is attached to the winding portion 21 of this part, or product information is printed. The merchandise information displayed on the winding unit 21 makes it easy to see the ingredients packed in the container body 11 by minimizing the product name, expiration date, price, etc. The product information may be displayed on the bottom surface of the container body 11.

  And the container main body 10 with a cover winds in the state which the band seal 20 contact | adhered, the cover 12 is not removed, it is shipped from a food factory, and is sold in stores, such as a convenience store. In this store, when the lunch is sold, the second heating is performed so that the food can be eaten in a warmed state. Since the product information is displayed on the band seal 20 wound around the container body 10 with the lid, and in order to prevent the lid 12 from being easily removed from the container body 11, The container body 10 with the lid is heated for the second time with the band seal 20 wound around.

  However, immediately before the second heating, the temporary bonding of the extra 22 of the bandage 20 is forcibly peeled off by hand or the like, and the bandage 20 is absorbed and integrated into the winding part 21 as shown in FIG. Thus, the container body 10 with the lid is surrounded with a margin. And by the second heating, the band seal 20 contracts and winds in a state of being in close contact with the container body 10 with a lid.

  In other words, if the margin of the banding 20 is too large, the banding 20 may not be wrapped around the container body 10 with the lid due to the second heating, and the lid 12 may come off. Conversely, the margin of the bandaging 20 is too small. And, by the second heating, the band seal 20 contracts until the container body 10 with a lid is deformed so as to be confined. Therefore, the margin of the bandage 20 that wraps around the container body 10 with the lid is such that the bandage 20 winds in close contact without deforming the container body 10 with the lid by the second heating.

  Then, the lid 12 is not detached from the container main body 11 by winding the band seal 20 in close contact with the container main body 10 with the lid by the second heating. In addition, when the bandage 20 is wrapped around the container body 10 with the lid and the product information is displayed on the bandage 20, the purchaser of the lunchbox can check the expiration date or price of the lunchbox. Furthermore, the lunch box purchaser can eat the warm lunch box.

  In addition, this invention can be variously changed within the range of the invention specific matter described in the claim, without being limited to the said embodiment. For example, the band seal 20 is not wound so as to be joined to the bottom surface of the container body 11 and the top surface of the lid body 12 but can be wound around the fitting portion between the container body 11 and the lid body 12. .

  Moreover, when it heats 3 times or more, the extra 22 according to the frequency | count can be bonded. Further, when the extra 22 temporary bonding is naturally weakened by the second heating, and the extra 22 temporary bonding is naturally peeled off, immediately before the second heating. The second heating can be performed without forcibly peeling off the extra 22 temporary bonding by hand.
