Description

  The present invention relates to a food container.

  In restaurants, foodstuffs and cooked products are sometimes stored temporarily in food containers (for example, cooking bats).

  For example, in a sushi restaurant, the different types of prepared sushi items are kept in containers in a container and stored in a refrigerator or stored in a refrigerator so that different types of sushi items do not touch each other. .

  Containers for storing the sushi material include, for example, food containers of a type that is washed and used repeatedly, such as metal cooking bats, and disposable food containers of inexpensive polystyrene and polypropylene. In recent years, the use of the latter inexpensive disposable food containers has been increasing.

  However, in places that handle large amounts of sushi such as conveyor belt sushi restaurants, this disposable type food container is used in a large amount a day, and all these used wastes become trash, and this trash is processed. Since the cost is also high, there is a problem that the cost for the container becomes larger than the case of using a food container of a type that is repeatedly used such as a cooking bat.

  In addition, conventional food containers of the type that are repeatedly used generally have a shape in which the periphery of the opening is folded and crushed (for example, a curling shape). After cleaning and drying, if the stacking (stacked storage) before becoming completely dry, the inner side of the lower food container and the outer side of the upper food container overlap in close contact, Since moisture does not easily dry in this overlapping portion (adherent portion), if moisture remains in this overlapping portion, there is a possibility that various bacteria will propagate due to this moisture, resulting in an unsanitary state. Therefore, after the cleaning / drying process, the stacking is not performed immediately after storing, but it must be left for a while after the drying process to dry completely and then stacked. In particular, curling-shaped ones are difficult to remove dirt on the periphery and inside the curling, and dirt is likely to remain at the time of washing. Could lead to

  Therefore, conventionally, even after the cleaning operation is completed, it cannot be immediately taken out from the washing machine, and even after the washing and drying operation of the tableware washing machine is finished, another food container cannot be washed immediately. Even if it is taken out from the washing machine and dried in another place, there is a problem that workability is lowered, for example, it is necessary to secure a wide place where many food containers can be arranged.

  Further, as described above, the conventional food containers of repeated use are generally stacked and stored when not in use, but the upper and lower food containers overlap in this stacked state. Since there is almost no gap between the peripheral portions (curling portions) of the food containers, when picking them up individually, between the food containers (the peripheral portion of the upper food container and the peripheral portion of the lower food container) There was also a problem that it was very difficult to pick up each individual.

  Therefore, in order to solve the above-described problems, a food container in which a convex portion or a step portion is formed on the inner peripheral surface of the container has been newly proposed.

  This food container has a structure in which the bottom of the upper food container is supported by this convex or stepped portion during stacking so that it does not overlap completely, so that the upper and lower food containers in the stacking state overlap each other in close contact. In addition, a gap into which the fingertip can be inserted can be formed between the peripheral edges of the upper and lower openings, and the conventional problems described above can be solved.

  However, a food container having a convex portion or a stepped portion formed on the inner peripheral surface of the container is difficult to clean by the convex portion or the stepped portion, and dirt is likely to remain at the base portion of the convex portion or the corner portion of the stepped portion. Also, when stacking, the bottom of the upper food container comes into contact with the inner surface of the lower food container, so that the dirt attached to the bottom of the upper food container There is a problem that it tends to become unsanitary due to adhesion to the inner surface, and furthermore, scratches due to rubbing are attached to contact parts such as convex parts and stepped parts, and dirt (miscellaneous bacteria) enters this scratch and is washed Sometimes it could not be removed, and there was a risk that germs would propagate from there.

  The present invention has been made in view of the current situation as described above, and can be dried even after stacking after cleaning for repeated use, and is not scratched during stacking. An object of the present invention is to propose a food container excellent in practicality that can easily pick up food containers individually from the state.

  The gist of the present invention will be described with reference to the accompanying drawings.

  An embodiment of the present invention which is considered to be suitable will be briefly described with reference to the drawings showing the operation of the present invention.

  Stacking with the opening of each food container facing upward so that the storage part of the upper container body 1 to be stacked is stored in the storage part of the container body 1, or the upper part of the container body 1 being stacked When the stacking is performed with the opening of each food container facing downward so as to be stored in the storage portion of the container body 1, the end of the pin 4 provided on the flange 2 of the container body 1 located on the lower side The end portion of the pin 4 provided on the flange portion 2 of the container body 1 located on the upper side comes into contact.

  Specifically, for example, when stacking is performed with the opening of each food container facing upward so that the storage part of the upper container body 1 to be stacked is stored in the storage part of the container body 1, the container body 1 is positioned on the lower side. The flange part 2 of the pin 4 provided in the collar part 2 of the container main body 1 located in the upper part at the front-end | tip of the surface side protrusion part 4A which protrudes to the collar part 2 surface side of the pin 4 provided in the collar part 2 of the container main body 1. The opening of each food container is placed on the lower side so that the tip of the rear surface side protruding portion 4B that protrudes toward the rear surface comes into contact, and the storage portion of the container body 1 is stored in the storage portion of the upper container body 1 to be stacked. When the stacking is performed, the flange portion of the container body 1 located on the upper side at the tip of the rear surface side protruding portion 4B protruding on the rear surface side of the flange portion 2 of the pin 4 provided on the flange portion 2 of the container body 1 located on the lower side. Surface side protruding part 4 protruding to the surface side of the collar part 2 of the pin 4 provided in 2 Tip of the contact.

  When the pins 4 are in contact with each other, the lower container body 1 and the upper container body 1 to be stacked are not in close contact with each other, and a gap 5 is formed between the lower container body 1 and the lower container body 1. Stacking is performed while maintaining the state of forming.

  Specifically, for example, when stacking is performed with the opening of the food container facing upward, the surface of the lower container body 1 and the flange 2 of the lower container body 1 and the upper container body to be stacked 1 and the back surface of the flange 2 of the upper container body 1 are not in close contact with each other, and there is a gap between the surface (inner surface) of the lower container body 1 and the back surface (outer surface) of the upper container body 1. When the stacking is performed while holding the state in which 5 is formed and the opening of the food container is placed on the lower side, the lower container body 1 and the back surface of the flange 2 of the lower container body 1, The upper container body 1 to be stacked and the surface of the collar part 2 of the upper container body 1 are not in close contact with each other, and the back surface (outer surface) of the lower container body 1 and the surface of the upper container body 1 (inner surface) ) And stacking with the gap 5 formed.

  That is, according to the present invention, when stacking, the pins 4 provided on the respective collars 2 come into contact with each other, so that the front surface or the back surface of the lower container body 1 and the back surface of the upper container body 1 to be stacked. Alternatively, a gap 5 is formed between the container body 1 and the surface, and a stacking structure is formed in which the upper container body 1 to be stacked overlaps with the lower container body 1 in a floating state.

  Therefore, even if stacking, the gap 5 is formed between the container main bodies 1 and between the flange parts 2 so that the ventilation between the container main bodies 1 and between the flange parts 2 is improved and can be dried in a stacking state. Miscellaneous bacteria do not propagate and can maintain hygiene, and for example, even if some moisture (humidity) remains immediately after the cleaning operation by the dishwasher, it is immediately taken out and stacked and left to dry. As a result, it is possible to immediately perform another food container cleaning operation, improving the operating rate of the dishwasher, and a small space for the food container storage space when left to dry. Therefore, it becomes an epoch-making food container with extremely excellent practicality.

  Conventionally, when stacking, food containers overlap each other in a close contact state, and thus the work of individually picking up the food containers in the stacking state is troublesome and troublesome work. Since a gap 5 is formed in the gap (specifically, between the ridge part 2 of the upper food container and the ridge part 2 of the lower food container), the food container is put into the gap 5 with a fingertip. Can be easily picked up individually, so that the conventional troublesome picking work is eliminated and the workability is improved and the food container is excellent in practicality.

  Furthermore, in the present invention, since the gap 5 is formed, the lower container body 1 and the upper container body 1 do not come into contact with each other even when stacking is performed, and therefore, scratches due to contact do not occur. Dirt (miscellaneous bacteria) enters the rubbing scratch and cannot be removed at the time of washing, and the possibility that the germs propagate from there is reduced as much as possible, and the food container is excellent in hygiene.

  In addition, for example, in the present invention, the pin 4 fixed to the flange portion 2 is squeezed on one end side or both end sides of the pin 4 in a state of being inserted into the pin insertion hole 3 so as to protrude in both front and back directions of the flange portion 2. In the state of being fixed to the flange part 2 by caulking, or in the state of being inserted into the pin insertion hole 3 so as to protrude in both front and back directions of the flange part 2, the periphery of the pin insertion hole 3 is crushed, and this crushing causes A configuration in which the opening edge portion 7 of the extended pin insertion hole 3 is fixed to the flange portion 2 by press-contact locking with the pin 4, or a state in which the pin insertion hole 3 is inserted in a protruding state in both front and back directions of the flange portion 2. Then, the periphery of the pin insertion hole 3 is crushed, and the opening edge portion 7 of the pin insertion hole 3 extending inward by this crushing is pressed and locked to the pin 4, and the opening edge portion 7 is pressed and locked. Then, crimp one end or both ends of this pin 4 to stop it. If it is configured to be fixed to the flange portion 2 by, for example, compared to the case where it is provided by welding, it can be provided easily and at a lower cost, and the surface side protruding portion 4A of the pin 4 and the surface of the flange portion 2 can be provided. If the gap between the projection 4B on the back side of the pin 4 and the back surface of the flange 2 is less likely to occur, the mounting state is clean, and, for example, the surface of the container body 1 is coated with an antibacterial coating, Then, the antibacterial coat is covered with welding, and the portion is easily stained, but the pin 4 can be provided without covering the antibacterial coat by caulking or pressing and fixing as in the present invention. As a result, an uncoated portion of the antibacterial coating is not generated, no dirt is attached, and excellent hygiene can be maintained.

  As described above, the food container of the present invention is an epoch-making food container excellent in economy, workability, and hygiene compared to disposable food containers and conventional food containers that are repeatedly used. It becomes.

  A specific embodiment 1 of the present invention will be described with reference to FIGS.

  The present embodiment relates to a food container for containing foodstuffs and cooked products. Specifically, pin insertion holes 3 are provided at a plurality of locations of the heel part 2 of the upper opening type container main body 1, The pin 4 is inserted into the pin insertion hole 3, one end side or both end sides of the pin 4 inserted into the pin insertion hole 3 are caulked, and the pin 4 is secured to the flange portion 2 by caulking to prevent the pin 4 is provided in a projecting state in both the front and back directions on the flange part 2 so that the storage part of the upper container body 1 to be stacked is stored in the storage part of the container body 1 or the storage part of the container body 1 Are stacked so as to be stored in the storage portion of the upper container body 1 to be stacked, the end of the pin 4 provided on the upper container body 1 to be stacked on the end of the pin 4 provided on the container body 1 The container body abuts the part Maintaining state in which the upper container body 1 is formed a gap 5 without contact to the stacking and those configured as stacking.

  More specifically, in this embodiment, the container body 1 is formed in a box shape having a planar view shape as shown in FIG. 1 and is inclined so that the lower side of each side surface enters the inside (side surface). (View) A so-called cooking bat formed in an inverted trapezoidal shape and configured to be stackable so that the bottom of the upper container body 1 to be stacked is housed in the upper opening of the lower container body 1 It is set as the structure formed in.

  Moreover, the container main body 1 of the present embodiment has a configuration in which a collar portion 2 made of a single metal plate material is extended to the opening edge of the upper opening. Specifically, in the present embodiment, the container main body 1 And the collar part 2 are set as the structure which integrally molded the metal plate material of 1 sheet by press work.

  In addition, in this container main body 1 and the collar part 2, it is good also as a structure which gave the antimicrobial coat to each of the surface and the back surface.

  More specifically, in the present embodiment, the four corners of the flange portion 2 are configured to have a shape having a horizontal plane portion wider than the linear flange portion 2 provided along the opening side portion. The pins 4 projecting in both the front and back directions are provided on the horizontal surface portions of the four corners of the portion 2.

  In the present embodiment, as shown in FIG. 2 (a), the pin 4 is formed in a cylindrical shape with the diameter of the pin insertion hole 3 being substantially the same diameter as shown in FIG. The surface side protruding portion 4A formed in a cylindrical shape having a larger diameter than the insertion hole 3 is provided, and the insertion portion 4C inserted through the pin insertion hole 3 provided in the flange portion 2 is deformed by applying pressure to the flange portion. By staking to 2, the pin 4 is provided on the flange 2 by staking.

  In addition, when the pin 4 of this embodiment is attached to the flange portion 2, the upper surface portion of the surface side protruding portion 4A protruding to the surface side of the flange portion 2 is formed in a shape bulging in a hemispherical shape or a curved shape. Further, it is configured such that moisture does not accumulate on the surface side protruding portion 4A and flows down during cleaning.

  The method for attaching the pin 4 will be described in detail. First, as shown in FIG. 2 (a), the pin insertion hole 3 is drilled in the horizontal surface portion of each corner of the collar portion 2, and then in FIG. 2 (b). As shown in FIG. 2 (c), the insertion portion 4C of the pin 4 is inserted into the pin insertion hole 3 from the upper side of the pin insertion hole 3 (the surface side of the flange portion 2). The insertion part 4C projecting to the back side of the part 2 is deformed by applying pressure to the collar part 2 to form the back surface side projection part 4B, and is fixed to the collar part 2 to complete the attachment.

  In this embodiment, in order to avoid a state in which the pins 4 do not come into contact with each other at the time of stacking, the box shape has a polygonal shape in plan view (planar view shape in this embodiment) that is not easily displaced. Although the container body 1 is formed, the shape of the container body 1 may be a circular shape in plan view, for example.

  In the case of this circular shape in plan view, in order to avoid the problem of displacement, for example, a concave portion is formed on the upper surface of the front surface side protruding portion 4A of the pin 4, and the concave portion is engaged with the lower end of the rear surface side protruding portion 4B. Or a convex portion formed on the upper surface of the front surface side protruding portion 4A of the pin 4 and a concave portion engaging with the convex portion at the lower end of the rear surface side protruding portion 4B. The pin 4 provided on the lower food container and the pin 4 provided on the upper food container are engaged with each other so that they are not easily displaced, and the pins 4 are kept in contact with each other and stacked. What is necessary is just composition. Of course, even when formed in the square shape of the present embodiment, a configuration in which the pins 4 are engaged with each other in a concave-convex manner may be adopted so as to be positioned more reliably.

  The operation and effect of the present embodiment configured as described above will be described below.
