Description

The present invention provides a container for use in the delivery of food and foodstuffs, to a internal tray container used in combination with the outer box.

  Conventionally, for example, as a container used for transporting sushi and other various cooked foods such as sushi rolls and inari sushi, or ingredients used for cooking, an outer box as a container body, and in the outer box Containers that combine trays as inner containers that are used in a stack are known. Such containers are repeatedly used as returnable boxes.

  The tray as the inner container of the container is formed of a synthetic resin molded body, and is fitted in the vicinity of the four corners of the bottom surface (bottom surface of the bottom) of the tray inside the opening of the lower tray when stacked. Protrusions for stacking are provided, and the protrusions are fitted inside the opening of the lower tray so that they can be used without being misaligned. For example, Patent Document 1 discloses a stack protrusion provided on the bottom surface of a tray made of a synthetic resin foam.

  In such a tray as an inner container, the stack projections provided at the four corners of the bottom surface are generally in the shape of a square or an L shape. In particular, in the case of a tray formed of non-foamed synthetic resin, the stacking projections provided at the four corners of the bottom surface have an L-shape that fits along the vertical and horizontal side walls adjacent at the four corners. There are many things.

  The convex portion having such a shape is likely to collect dirt and water at the boundary portion between the side surface and the bottom surface, and dirt tends to remain even after washing. In particular, in the case of an L-shaped protrusion, the corner portion on the inside of the L-shape becomes a blind spot during cleaning, and it is difficult to remove dirt. Therefore, it takes time to clean the container internal tray for repeated use.

Therefore, it is desired that the stack protrusions of this type of container internal tray can exhibit positioning and misalignment prevention effects during stacking, and are not easily contaminated and easily removed.
Japanese Utility Model Publication No. 7-37973

  The present invention has been made in order to solve the above-described problem. As a tray inside a container to be stacked and used in an outer box as a container body, stacking protrusions for stacking in a simple form. Although it is effective for positioning and preventing misalignment during stacking, it is difficult for water and dirt to collect during cleaning, and it is easy to remove water and dirt so that cleaning for repeated use can be performed easily. It is a thing.

The present invention for solving the above-mentioned problems is a flat rectangular synthetic resin tray that is used in a stack as an outer box as a container body used for transporting foods and foods, and has four corners on the bottom surface of the tray . In each, there are provided stacking protrusions that protrude in pairs along adjacent vertical and horizontal side walls, and the protrusions of the two pairs each have a hemispherical tip , and are stacked when the trays are stacked. Are fitted into the inside of the opening of the lower layer tray so as to contact the inner surfaces of the corresponding vertical and horizontal side walls of the lower layer tray .

  When the tray for the inside of the container having the above structure is used for stacking in the outer box as the container body with contents such as food stored therein, the stacking protrusions provided at the four corners of the bottom surface are hemispherical at the tip. Because it is shaped, it is easy to fit inside the opening of the lower tray, and in the fitted state, it will be along the vertical and horizontal side walls adjacent to the lower tray, so it can prevent vertical and horizontal displacement movement, It can be stacked stably at a predetermined position.

  In addition, since the protrusions protrude in a hemispherical shape, unlike square or L-shaped protrusions, it is difficult for water and dirt to collect during cleaning, and it is difficult to get dirt. The dirt can be easily removed. That is, cleaning for repeated use can be easily performed and used hygienically.

Further, as described above, the stacking projections are provided in pairs along the vertical and horizontal side walls adjacent to each other at each of the four corners on the bottom surface, and the two projections correspond to the lower tray when stacked. by fitted to the lower tray along in contact with the inner surface of the side wall, can be reliably prevent displacement of the vertical and horizontal.

  Further, in the case where the protrusion is formed so that the end is formed in a hemispherical shape continuously with the base side surface perpendicular to the bottom surface, the protrusion fits inside the opening along the adjacent vertical and horizontal side walls in the stacked state. Since the protruding protrusion is in contact with the side wall at the vertical base side surface, even if a lateral force is applied to the upper tray, there is no risk that the protrusion will ride on the upper end of the side wall, and the stacked state is stable. Can be held.

  In the tray, a flange that can contact the inner wall surface of the outer box protrudes from the upper end of the side wall on one opposite side, and a notch for handling is provided in a part of the flange. preferable. In this case, in the stacking use of the tray in the outer box, the flange is in contact with the inner wall surface of the outer box, so that the excessive swinging movement of the tray in the outer box cannot be regulated and a stable stacking state is achieved. Can hold. In addition, even when the gap between the flange and the inner wall surface is narrow as described above, the tray is handled by holding the tray at the notch and the tray is stacked in the outer box, and the stacked tray is taken out. Can be done without difficulty.

  Further, in the above tray, in the case where at least one opposing side wall outer surface is provided with a vertical rib whose lower end is flush with the bottom surface, stacking strength can be secured by the vertical rib, and the upper layer Even if the tray moves sideways and the edge of the bottom surface deviates from the upper end of the side wall of the lower layer tray, the lower end of the vertical rib is mounted on the upper end of the side wall of the lower layer tray. The tray does not tilt or fall over.

  According to the container internal tray of the present invention, since the stacking protrusions for stacking protrude in a hemispherical shape, water and dirt are difficult to collect during cleaning, and are not easily contaminated. Even if there is a mark, the dirt can be easily removed, so that cleaning for repeated use is facilitated and it can be used hygienically.

  In particular, when the protrusion is continuous with the base side surface perpendicular to the bottom surface and the end has a hemispherical shape, the base side surface of the protrusion fits along the inner side wall of the lower tray when stacking trays. The effect of preventing lateral displacement can be ensured, and a stable stacked state can be maintained even if it protrudes in a hemispherical shape.

  Next, embodiments of the present invention will be described based on examples shown in the drawings.

  FIG. 1 is a perspective view showing a container internal tray and an outer box as a container body according to the present invention, and FIGS. 2 to 5 are a plan view, a bottom view, a front view, and a side view of the container internal tray, 6 is a partially enlarged perspective view of the bottom side of the tray, FIG. 7 is an enlarged view of the protrusion, FIG. 8 is a sectional view of the tray, and FIG. 9 is a sectional view in which the trays are stored and stacked in the outer box as the container body. FIG. 10 is an enlarged view of the same part.

  In the figure, reference numeral 10 denotes a container internal tray made of a synthetic resin molding according to the present invention, and 20 denotes an outer box (lid is omitted) as a container body.

  The container internal tray 10 of the present invention corresponds to the internal form of the outer box 20 by the bottom part 11 and the side walls continuously provided around the circumference thereof, that is, the front and rear and left and right side walls 12, 12 and 13, 13. It is formed so as to form a container that opens upward in the form of a plane rectangle, and is formed so that it can be used in a plurality of stages in the outer box 20. In other words, the inner dimension of the opening at the upper end of each of the side walls 12, 12, and 13, 13 is formed to be slightly smaller than the outer dimension of the lower end of the side wall, that is, the outer dimension of the bottom portion 11, and the bottom portion 11 during stacking is formed. Is formed so that the peripheral edge of the bottom surface 11a, which is the lower surface, is in contact with the upper ends of the side walls 12, 12, and 13, ie, the opening. Usually, each of the side walls 12, 12 and 13, 13 has a slight draft for molding, but this draft is within the range of the thickness of each side wall (preferably ½ of the thickness). It is formed so that it can be stacked as described above.

When the tray 10 of the present invention, for positioning and preventing displacement at the time of the stack, the four corners of the bottom surface 11a, the stack of earlier end with flat circular each protruding downward direction forms a hemispherical shape Projections 15 are provided along the vertical and horizontal side walls 13 and 12 adjacent to the corners of the opening of the lower tray 10 when the trays 10 are stacked . 9 and FIG. 10, it is provided slightly inside the peripheral edge of the bottom surface 11a so as to be fitted in a contact state .

In the case of the present invention , the projections 15 are provided in pairs along the adjacent vertical and horizontal side walls 13 and 12 at each of the four corners of the bottom surface 11a. One set of projections 15, 15 are provided to fit into the opening inside the lower tray 10 along in contact with the corresponding inner surface of the vertical and horizontal side walls 13 and 12 of the lower tray 10.

As described above, the projections 15 for each four corners stock, the displacement prevention effect, in terms of stability in the case of placing on a table, those to be provided in pairs as shown And Further, collision number of raised higher increases, so it becomes difficult dirt during washing, preferably preferably provided with by Uni pairwise you shown.

Anyway, the protrusion 15, previously end continuously to the bottom surface 11a in the vertical of the base side 15a is formed so as to form a hemispherical shape, the base side 15a is lower tray 10 in the stacked state of the tray 10 It is formed so as to be in contact with the vertical and horizontal side walls 13 and 12 and to be engaged laterally. Thereby, the effect of preventing misalignment of the stacked trays 10 can be enhanced, and a stable stacked state can be maintained.

  The size of the front protrusion 15 is generally in the range of, for example, a diameter of 4 to 10 mm and a height of 3 to 10 mm, but of course, it can be a dimension outside the above range, depending on the size and contents of the tray. It can be set appropriately.

  In the tray 10 of the illustrated embodiment, flanges 16, 16 projecting outward are respectively provided on the opposite side walls, for example, the upper ends of the left and right side walls 13, 12. When stacked and used, it is formed so as to abut against the inner wall surface 21 of the outer box 20 or to have a slight gap, so that play in the outer box 20 can be restricted. 17 and 17 are notches for handling formed in the flanges 16 and 16, and the tray 10 is lifted at the portions of the notches 17 and 17, stored in the outer box 20, stacked, and taken out from the outer box 20. You can do that. Protruding edges 18 and 18 slightly projecting outward are also provided at the upper ends of the opposite side walls 13 and 12.

  Reference numerals 19 and 19 denote vertical ribs formed on at least one opposite side wall, for example, the outer surfaces of the left and right side walls 13 and 13. The vertical ribs 19 and 19 have lower ends flush with the bottom surface 11a. Even when the stacking strength is secured by the vertical ribs 19, 19 and the upper tray 10 is laterally displaced during stacking and the bottom surface 11 a is disengaged from the upper end of the side wall 13 of the lower tray 10, Since the lower ends of the vertical ribs 19 are in contact with the upper ends of the side walls 13 of the lower layer tray 10, the stacked ribs are provided as they are.

  In the case of the tray 10 shown in the figure, the bottom portion 11 is formed so as to have a warped shape in which the central portion swells slightly above the peripheral portion, for example, about 1 to 2 mm, and has a reinforcing rib on the bottom surface. Even if the like is not formed, excessive bending deformation of the bottom portion 11 due to the load of the contents can be restricted.

  The tray 10 can be made of ABS resin or any other synthetic resin generally used for food storage, and is usually integrally formed by injection molding with the non-foamed resin. The size and depth of the tray 10 are set according to the food to be stored. For example, when storing thick sushi rolls, the tray 10 is set to store general sushi roll rolls. The thickness of the tray 10 is usually set to 1 to 3 mm, preferably about 2 mm. Depending on the contents to be stored and the size of the tray, one outside the above range can be used.

  The container outer box 20 used in combination with the tray 10 can store the tray 10 with little lateral movement or swinging, and has a plurality of stages (preferably three or four stages). It consists of things that can be stacked. As the outer box 20, in the case of a heat insulating container used for transportation in a heat and cold state, a foamed resin is used between an inner body 22 and an outer body 23 made of a non-foamed synthetic resin as shown in the figure. The core material 24 is formed as an insulating layer. In this case, a lid that is not shown is configured in the same manner as described above. Of course, a single molded container of synthetic resin foam can also be used. In the case of a container that does not require heat insulation and cooling, an outer box formed of non-foamed synthetic resin can also be used.

  The container internal tray 10 of the present invention having the above-described configuration is stored in an outer box 20 as a container body in a state in which contents such as food are stored, and stacked and used as shown in FIG.

At this time, the stacking projections 15 provided at the four corners of the bottom surface 11a of the tray 10 have a hemispherical shape protruding from the tip , so that they are fitted inside the opening of the lower tray 10. In the state where it is easy to fit, the projections 15 are in contact with the inner surfaces of the adjacent vertical and lateral side walls 13 and 12 of the lower tray 10, and in particular , the base side surface 15a of the projection 15 is perpendicular to the bottom surface 11a. If, because the base side 15a will be taken along in contact with the inner surface of the side walls 13 and 12, can be prevented before and after the left and right lateral displacement movement of the tray 10, it is stacked well stability at a given position it can. Further, as shown in the figure, when the flanges 16, 16 provided at the upper ends of the opposite side walls 13, 13 are in contact with the inner wall surface 21 of the outer box 20 or there is a slight gap, Excessive shaking movement of the tray 10 in the outer box 20 can be restricted, and a more stable stacked state can be maintained.

  Moreover, since the protrusion 15 protrudes in a hemispherical shape, unlike a square or L-shaped protrusion, it is difficult for water and dirt to collect during cleaning, and it is difficult to get dirt. Even in this case, the dirt can be easily removed. That is, cleaning for repeated use can be easily performed and used hygienically.
