Description

  The present invention relates to a food packaging container suitable for packaging foods such as rice cakes, curry roux, noodle soup, spaghetti sauce, etc. that are eaten on or over rice. More specifically, the present invention relates to a food packaging container that can be easily heated and can be used in various ways, and particularly suitable for use in the restaurant industry.

  As a packaging container for eating spaghetti deliciously, for example, a packaging container disclosed in Patent Document 1 has been proposed.

  The packaging container has a bottomed box-shaped container body having an open upper end, a dish-shaped inner lid placed on the container body, and an outer lid placed on the inner lid. A planned opening portion closed with a sealing material is formed at the center of the inner lid. Further, a notch for exposing the end of the sealing material to the outside is formed in a part of the upper end edge of the container body.

  In packaging, spaghetti is accommodated between the container body and the inner lid, and the source is accommodated between the inner lid and the outer lid. When eating, heat in a microwave oven as it is, warm the spaghetti and sauce separately, remove the sealing material and apply the sauce to spaghetti.

  However, when heating in a microwave oven, it is necessary to make a hole for escape of steam, so the work for that is not easy, and if neglected, a problem arises in terms of safety. Further, since the container body has a notch for exposing the end of the sealing material, it is a problem in terms of the hygiene of food contained in the container body, and cannot be used for packaging food that is not eaten early after packaging.

  Similarly, Cited Document 2 discloses a packaging container capable of separately storing utensils and rice and rice. This packaging container has a configuration in which a flange is provided on the periphery of the lower surface opening of the lid, and a bent portion is formed on the outer periphery of the flange. A partition film is joined to the flange to close the opening of the lid. The bent portion is fitted into the container body. The partition film is formed with a gripping portion that becomes the beginning when the film is peeled off, and a gap is formed between the bent portion and the container body in order to accommodate the gripping portion.

  In the case of such a packaging container as well as the packaging container of Patent Document 1, it is necessary to separately provide a vapor escape path when heating in a microwave oven. Moreover, since the said cover body is an internal fitting type | formula and there exists the said clearance gap, there exists a problem also in the sanitary aspect of the foodstuff accommodated in the container main body.

  In this regard, as described in Patent Document 3 below, the lid that covers the container body is provided with an accommodating portion that has an openable lowering portion that allows food to flow down at the bottom, and an openable ventilation portion is formed on the upper surface of the lid. In the case of the packaged container, safety can be ensured upon heating in the microwave oven by opening the ventilation portion.

  However, since the container body, the container, and the lid are structured so as to cover each other in order, it is good for packaging food that is eaten relatively early after packaging, but food that is eaten with time after packaging. It was unsuitable for packaging. This is because secondary sterilization cannot be performed. That is, cooked foods need to be secondarily sterilized after packaging except for those that are eaten immediately, but like the packaging container of Patent Document 3, a container is fitted on the container body. The structure in which the lid is fitted thereon cannot perform secondary sterilization. The same applies to the packaging container of Patent Document 1.

Japanese Utility Model Publication No. 1-122481 Japanese Patent No. 2875196 Registered Utility Model No. 3133066

  Thus, the present invention can be easily heated and can be used in a variety of ways, from packaging of food eaten relatively early after packaging to packaging of food eaten at a later time after packaging. This is the main issue.

  The means for this is a food packaging container having an accommodation recess for containing food, and the lid sheet material that protrudes outward from the entire circumference of the upper end of the accommodation recess and closes the accommodation recess is heat-sealed. A seal portion is formed, and a concave groove is formed outside the heat seal portion and below the heat seal portion. The heat seal portion penetrates in the thickness direction to allow ventilation. The food packaging container is provided with a vent hole that is closed by fixing the lid sheet material after the food is stored in the storage recess.

  In this configuration, the food stored in the storage recess is closed by thermal welding of the lid sheet material, so that it is protected during secondary sterilization or hot water bathing. The concave groove is hooked when the food packaging container is turned upside down and placed on a container such as tableware or a packaging container, and allows the food contained in the housing recess to be discharged easily and cleanly. And since the said vent hole peels off a cover sheet material, when it covers a food packaging container on a suitable container and heats it with a microwave oven, it acts as a vapor release and ensures safety. In addition to completely removing the lid sheet material from the heat seal portion, the lid sheet material may be peeled off to such an extent that the vent hole is opened and the accommodating recess is slightly opened. In this case, the food packaging container is covered. In this state, the food in the housing recess and the food in the container are heated separately.

  Another means is food that has been secondarily sterilized after being packaged in the food packaging container.

  In this configuration, the quality of the food in the housing recess is maintained for a while after packaging by secondary sterilization.

  Still another means includes a food packaging step for packaging food in the food packaging container, and a packaging container having a fitted edge portion to which the concave groove of the food packaging container is fitted at the upper end in the food packaging step. A food assembling step for serving food to be eaten together with the packaged food, and a combination step for covering the food packaging container on which the food is packaged at the food packaging step with the packaging container on which the food is served at the food assembling step It is the usage method of a food packaging container.

  In this configuration, food such as rice cake is prepared by packaging in the food packaging step, food such as rice and noodles is served in the food preparation step, and then the food packaging step is performed in the combination step. When the food container is put on the packaging container that has undergone the food filling step, the food container can be handed over to the customer.

  According to the food packaging container of the present invention, the food in the housing recess is closed by the lid sheet material, so that the secondary sterilization and hot water can be performed. For this reason, the packaging of the food which is not eaten immediately after packaging is also possible, and the sanitary safety can be ensured. In the restaurant industry, it is particularly convenient for providing take-out products. In addition, since the vent hole is automatically opened when the lid sheet material is peeled off, the preparatory work for heating is easy, and the safety is maintained even when the food packaging container is put on the microwave oven.

  In addition, according to the method of using the food packaging container of the present invention, the food that has undergone the food packaging step is heated in, for example, a hot water bath, and the product can be provided simply by covering the packaging container that has undergone the food filling step. For example, when used for take-out of products such as beef bowl, the waiting time can be greatly shortened, and it is convenient because a large number of orders can be handled quickly in a small space.

An embodiment for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing a state in which food 71 is packaged in a food packaging container 11, and this food packaging container 11 is a packaging container having a cup shape or bowl shape, for example, as shown in FIG. 51 or a tableware such as a bowl (not shown).

  That is, the food packaging container 11 contains the food 71 as a secondary ingredient such as rice cake, curry roux, noodle soup, spaghetti sauce, etc., for example, main ingredients such as rice and noodles. It is preferably used when it is provided so that it can be eaten by being placed on or over the food 72 (see the phantom line in FIG. 2). It can also be used alone.

  FIG. 3 is a perspective view of the food packaging container 11, which is formed by vacuum forming a synthetic resin sheet. It is circular in plan view as a whole, and has a bottomed short cylindrical storage recess 12 for storing food 71 in the center. On the entire circumference of the upper end of the housing recess 12, a bowl-shaped heat seal portion 13 that protrudes outward with the same width is formed.

  The heat seal portion 13 is a portion to which a lid sheet material 31 (see FIGS. 1 and 4) that closes the housing recess 12 is thermally welded. A concave groove 14 is formed at a lower position all around the outside of the heat seal portion 13 and lower than the height of the heat seal portion 13. 5, when the food packaging container 11 is turned upside down and positioned above the packaging container 51 or tableware (not shown), as shown in FIG. While being a part caught in the engaging edge part 52 of an upper end edge, it is a part fitted with respect to the packaging container 51 as shown in FIG. The upper end of the packaging container 51 is inclined so as to open to the outer peripheral side as it goes upward, and the food packaging container 11 includes the heat seal part 13, so the radial width of the groove 14 is It is set to be larger than the thickness of the engagement edge 52 of the packaging container 51 in the inner and outer directions. In other words, an appropriate space 54 is formed between the inner peripheral wall surface 14 a of the concave groove 14 and the inner peripheral surface 53 of the upper end edge of the packaging container 51.

  Further, a locking projection 15 that protrudes inward is formed on the outer peripheral wall surface 14 b in the concave groove 14 in order to maintain a locking state with respect to the engagement edge 52 of the packaging container 51. The locking protrusion 15 is appropriately formed according to the packaging container 51, tableware, etc., and can be omitted if unnecessary.

  The concave groove 14 is not necessarily formed on the entire circumference of the heat seal portion 13, but in order to maintain the quality of food, the concave groove 14 is formed on the entire circumference so that the fitting state with respect to the packaging container 51 is maintained. It is preferable to keep it well.

  The heat seal portion 13 is formed with a vent hole 16 that penetrates in the thickness direction and allows ventilation. The size, shape, structure, number, and arrangement of the vent holes 16 are set as appropriate. For example, in the illustrated example, it is configured with a round hole, but it may be a U-shaped hole.

  The vent hole 16 is closed by the lid sheet material 31 as shown in FIG. 4 when the lid sheet material 31 is thermally welded to close the housing recess 12.

  The food packaging container 11 having such a structure is attached with the lid sheet material 31 as shown in FIG. Further, if necessary, the container (such as the packaging container 51) having an engagement edge portion with which the recessed groove 14 turned upside down is engaged is attached.

  The lid sheet material 31 is formed of an appropriate material that can be thermally welded to the heat seal portion 13, and a main body portion 32 that closes the housing recess 12 and a belt-like shape that extends from one end portion 32 a of the main body portion 32. The folded overlap portion 33 is provided. The main body 32 is a circle having a size substantially corresponding to the outer peripheral edge of the heat seal portion 13. The folded overlap portion 33 extends toward the other end portion 32b and extends from the other end portion 32b of the main body portion 32 as shown in FIG. 1 when folded at the root portion of the one end portion 32a, that is, the folded overlap portion 33. Is also formed in a length protruding outward. Since this protruding portion in the folded overlap portion 33 becomes the knob portion 34 when the lid sheet material 31 is peeled off, the protruding length of the knob portion 34 is appropriately set so that the lid sheet material 31 can be easily peeled off.

  The food packaging container 11 configured as described above is used as follows using the lid sheet material 31. In this example, a product of a food dealer and a take-out product in the restaurant industry will be described.

  First, it is food packaging step S1 for packaging food 71. As shown in FIG. 7, the storage recess 12 of the food packaging container 11 is placed so that the top is opened (see FIG. 7A), and a predetermined food 71 is stored (see FIG. 7B). ). After the predetermined amount of food 71 is stored, the lid sheet material 31 is fixed by heat welding, and the storage recess 12 is closed (see FIG. 7C).

  Then, it transfers to secondary sterilization step S2 as needed. In the secondary sterilization step S2, as shown in FIG. 8, the packaged food packaging container 11 is heated at a predetermined temperature by a known secondary sterilization apparatus 75 for a predetermined time. Thereafter, the packaged food packaging container 11 is cooled and then shipped.

  As described above, the food 71 that has been secondarily sterilized after being packaged in the food packaging container 11 itself becomes a commercial product.

  In the case of take-out products in the food service industry, after the food packaging step S1 and the secondary sterilization step S2 are shipped, or when the food packaging step S1 is performed at a sales store, the food packaging step S1 is performed. After a lapse of time, the process proceeds to food filling step S3 in which food is placed in the packaging container 51.

  In the food serving step S3, as shown in FIG. 9A, the food 72 as the main food material is served in the packaging container 51. That is, rice, noodles, spaghetti, pasta, or the like is accommodated in the packaging container 51 having an engaging edge with which the concave groove 14 of the food packaging container 11 is engaged at the upper end edge. More specifically, the food container 72 is accommodated after the packaging container 51 is held and placed on a work table (not shown).

  Thereafter, the process proceeds to the combination step S4. In the combination step S4, the food packaging container 11 in which 71 foods are packaged is turned upside down so that the groove 14 faces downward as shown in FIG. 9B, and then the food 72 is filled in the food filling step S3. Cover the resulting packaging container 51 (FIG. 9C). That is, the food packaging container 11 heated by hot water bath or the like is sequentially fitted into the packaging container 51 placed on the work table, so that the food packaging container 11 and the packaging container 51 are integrated.

  At this time, since there is a space 54 (see FIG. 6) between the inner peripheral wall surface 14a of the groove 14 and the packaging container 51 as described above, the knob portion 34 of the lid sheet material 31 is in the space 54. In addition, since the concave groove 14 surrounds the entire circumference of the heat seal portion 13 and has wall surfaces 14a and 14b inside and outside, a perfect fitting state can be obtained so that there is no excessive air flow. . For this reason, food can be handled under good hygiene conditions.

  The foods 71 and 72 are provided to the customer in this state. The operation of placing the food 71 as a side food on or over the food 72 as the main food can be integrated with the operation of covering the lid, and the labor of the operation is greatly simplified. In addition, after the food packaging container 11 is placed on the packaging container 51 placed on the work table, these can be stacked, so that the work space on the work table can be reduced. For this reason, even when orders for take-out products are flooded at one time, it is possible to achieve both in-store meals.

Next, the use of the food packaging container 11 on the customer side who has received such a product will be described.
The customer opens the food packaging container 11 a little as shown in FIG. 10 and then pulls out the knob portion 34 of the lid sheet material 31 and keeps the food packaging container 11 on the packaging container 51. Pull. Then, the accommodation recessed part 12 of the food packaging container 11 is opened, and the contained food 71 is dropped and placed on the food 72 as a main ingredient such as rice.

  At this time, when the lid sheet material 31 is peeled off, the vent hole 16 in the heat seal portion 13 of the food packaging container 11 is opened as shown in FIGS. 11 and 12. For this reason, even when the food packaging container 11 is perfectly fitted to the packaging container 51 and covered, the vent hole 16 serves as an escape route for the steam S, so that it can be heated safely in the microwave oven. That is, even when the food is cold, it can be eaten in a warm and delicious state.

  Further, when the lid sheet material 31 is peeled off, there is a ventilation hole 16 and air enters from the outside. Therefore, even if the food packaging container 11 is fitted to the packaging container 51, the inside of the housing recess 12 The food 71 falls smoothly.

  When the food 71 in the food packaging container 11 and the food 72 in the packaging container 51 are to be heated separately, the lid sheet material 31 is not peeled off completely, and the ventilation holes 16 are opened as shown in FIG. A part of the housing recess 12 may be opened and heated. In this case, after the foods 71 and 72 are separately heated, the food 71 in the food packaging container 11 can be eaten together with the food 72 in the packaging container 51.

  As shown in FIG. 14, when the vent hole 17 is separately formed on the bottom surface of the housing recess 12 of the food packaging container 11 and closed with the peelable sealing material 18, the lid sheet material 31 is removed as described above. Even if it does not open until the accommodation recessed part 12 is opened, the two foodstuffs 71 and 72 can be heated separately. In this case, even when the food 71 in the food packaging container 11 has a low viscosity or contains a juice, it does not have to be mixed before heating, but the manufacturing cost is high. For this reason, it can be configured as shown in FIG. 15, for example.

  That is, a difference is made between the height of the heat seal portion 13 at one end and the other end, and the lid sheet material 31 is peeled off from a portion that becomes a high position when inverted upside down. In FIG. 15, 13 a is a portion where the heat seal portion 13 is low, and 13 b is a portion where the heat seal portion 13 is high. According to this configuration, when the food packaging container 11 is put on the packaging container 51, the highly fluid portion 71a of the food 71 is accumulated at a low position, that is, at the position 13b where the heat seal portion is high. Therefore, even if the accommodation recess 12 is partially opened, the food 71 can be prevented from entering below. As a result, mixing before heating can be prevented.

  As described above, the food packaging container 11 is suitably used for packaging the food 71 as a side food, and by performing secondary sterilization as necessary, it can be used for foods such as lunch boxes that are eaten early after packaging. It can be used not only for packaging, but also for packaging food that takes time to consume after packaging.

  When the food is not eaten by being placed on the food 72 as the main food, the lid sheet material 31 can be peeled off with the lid sheet material 31 side up and eaten. At this time, the food packaging container 11 serves as a container such as a plate or a cup, not as a lid.

  In addition, since the groove 14 is formed in the food packaging container 11, when eating together with the food 72 as the main ingredient, a part of the groove 14 is shown in FIG. Since the food 71 in the food packaging container 11 is not spilled outside, it can be put on and placed cleanly.

  When the lid sheet material 31 is peeled off, the vent hole 16 is opened. Therefore, even if the food packaging container 11 is covered with a container such as the packaging container 51 and heated with a microwave oven, the vent hole 16 is still in the vapor S ( Therefore, safety during heating can be ensured.

  In addition, since the vent hole 16 is opened by peeling the lid sheet material 31 necessary for discharging the food, the preparatory work for heating is easy, and the vent hole can be opened separately using a sealing material. The manufacturing cost can be reduced as compared with the case of forming.

  The food packaging container 11 has the vent holes 16, but it does not necessarily have to be heated and eaten. It may be eaten without heating, and food 71 that does not require heating, such as iron flame or trolley It may also be used as a packaging for rice, soba or chilled Chinese soup.

  Even if it is a packaging for both hot and cold foods, it will be deliciously eaten, unlike the case of combining from the beginning.

  Moreover, the food 71 and 72 can be combined with each other without spilling outside and without soiling the hands, as described above, by simply pulling the lid sheet material 31. Therefore, the work for eating is very simple. . In addition, the generation of dust can be suppressed as compared with, for example, packaging juice in a separate bag.

  Moreover, when the usage method of the food packaging container 11 which has the said food packaging step S1, the food preparation step S3, and the combination step S4 is employ | adopted, as mentioned above, the food packaging step S1 was carried out heat insulation and cold preservation beforehand. Simply put the packaged food packaging container 11 on the packaging container 51 newly prepared in the food preparation step S3, so that it can be provided to the customer. Is possible. Less work space is required. For this reason, it becomes possible to smoothly provide take-out products while eating in-store meals, and work congestion can be eliminated.

  In addition, as described above, for the customer, the foods 71 and 72 can be aligned immediately before eating, and can be eaten after being heated. For this reason, you will be able to eat deliciously, which will contribute to improving customer service.

In correspondence between the configuration of the present invention and the above configuration,
The container of the present invention corresponds to the packaging container 51,
The present invention is not limited to the above-described configuration, and other configurations can be employed.

  For example, when the food contained in the food packaging container 11 is eaten in the store, the container may be tableware such as a bowl used in the store.

  Also, a plurality of receiving recesses 12 can be provided, and can be divided into a plurality of partitions.
