Description

  The present invention relates to a plastic food tray for containing a glass container, a plastic container, a paper container, or the like containing foods such as cakes, puddings, mousses, jelly, and Japanese sweets.

  Conventionally, various kinds of containers having different shapes and sizes, such as glass, plastic and paper, have been used as containers for food. Food is put in these many kinds of containers and sold, and the seller puts the various kinds of containers containing food purchased by the customer in a box so that they can take it home. In order to prevent the container from moving unexpectedly in the box while the customer is bringing back a box containing various types of containers, a piece of paper to fill the gap between the containers It is done to stuff.

According to the said structure, the magnitude | size of the clearance gap which generate | occur | produces in a box changes with the quantity and the kind of the container in which the purchased foodstuff entered. Therefore, the amount of paper put in the box has to be adjusted according to the size of the gap, which is troublesome.
Moreover, even if a piece of paper is put in the box and the gap generated between the containers is filled, the container cannot be positioned reliably, and the container is sufficiently prevented from moving unexpectedly in the box. There was room for improvement.

  Accordingly, the present invention has been made in view of such circumstances, and provides a food tray that can easily and surely prevent a plurality of containers with different sizes of food from moving unexpectedly in a recess. The task is to do.

  The food tray according to the present invention is a plastic food tray provided with a plurality of recesses for accommodating containers containing food, wherein each recess stands from the bottom wall and the outer peripheral edge of the bottom wall. A raised first side wall, a second side wall having a diameter larger than that of the first side wall and raised from the upper end of the first side wall via a step portion; and an outer peripheral edge of the bottom wall And a protruding portion that protrudes upward to come into contact with the outer surface of the lower end portion of the container placed on the bottom wall.

  According to the present invention, the first side wall, the second side wall, and the projecting portion are provided by providing the first side wall, the second side wall, and the projecting portion in each of the concave portions. It is possible to prevent the outer surface of the container from coming into contact with any one of the parts, and the container from moving in the recess. In addition, since the two side walls and the protrusions formed in the first side wall are used, the three side walls having different diameters are formed above and below the concave portion as compared with the case where the two side walls are formed in the vertical direction. The dimension in the direction can be reduced.

  In addition, the food tray according to the present invention may further include a tapered third side wall that rises from the upper end of the second side wall and is positioned on the outer side toward the upper end side.

  As described above, by providing the tapered third side wall, a container having a diameter larger than that of the second side wall can be accommodated in the recess so as not to move unexpectedly. Moreover, since it is a taper, any container of any size that can fit within the taper can be securely stored in the recess so that it does not move unexpectedly. it can.

  In addition, the food tray according to the present invention has a bulging portion that rises so that the lower surface of the container is located higher toward the center, and a bulging portion that contacts the raised portion of the container at the center of the bottom wall May be provided.

  As described above, when the bulging portion at the center of the bottom wall comes into contact with the raised portion on the lower surface of the container, the bulging portion at the center of the bottom wall becomes the movement resistance of the container, and the container unexpectedly enters the recess. It is possible to further prevent the movement.

  Moreover, as for the food tray which concerns on this invention, the said protrusion part may be comprised from the some protrusion which protrudes upwards at predetermined intervals in the circumferential direction.

  As described above, the projecting portion is composed of a plurality of projections projecting upward at a predetermined interval in the circumferential direction, so that the material cost can be reduced as compared with the case where the projecting portion is composed of an annular projection.

  In the food tray according to the present invention, the second side wall is formed in a tapered shape located on the outer side toward the upper end side, and the taper angle of the second side wall is smaller than the taper angle of the third side wall. May be set.

  As described above, by setting the taper angle of the second side wall to be smaller than the taper angle of the third side wall, for example, a vertically long container having a small diameter can be stably and reliably secured by the second side wall having a large contact area. Can be held.

  As described above, according to the present invention, each of the recesses includes the first side wall, the second side wall, and the protruding portion, so that a plurality of containers can be formed in the recess only by accommodating containers having foods having different diameters. It is possible to provide a food tray that can easily and reliably prevent unexpected movement inside.

It is the side view which made the food tray which concerns on this invention the partial cross section. The tray for foodstuffs is shown, (a) is a top view, (b) is a front view. It is sectional drawing which accommodated the 1st container in the recessed part of the tray for foodstuffs. (A) is sectional drawing which accommodated the 2nd container in the recessed part of the food tray, (b) is sectional drawing which accommodated the 3rd container in the recessed part of the food tray. (A) is sectional drawing which accommodated the 4th container in the recessed part of the food tray, (b) is sectional drawing which accommodated the 5th container in the recessed part of the food tray. (A) is sectional drawing which accommodated the 6th container in the recessed part of the food tray, (b) is sectional drawing which accommodated the 7th container in the recessed part of the food tray.

  Hereinafter, an embodiment of a food tray according to the present invention will be described with reference to the drawings.

  1 and 2 (a) and 2 (b) show a food tray 2 in which three recesses 1 capable of accommodating a container containing food are formed. The food tray 2 is carried in a state of being placed in a box 3 (may be a container with a lid) indicated by a two-dot chain line in FIG. The box is provided with a lid (not shown) that can be opened and closed at the upper end, and the food tray 2 can be put into or taken out of the box 3 by opening the lid. In FIG. 1 and FIGS. 2 (a) and 2 (b), the front and rear direction, the left and right direction, and the up and down direction are determined by arrows, and description will be made based on these determined directions. Here, although the case where the food tray 2 is carried in the box 3 is described, the food tray 2 containing the container containing the food may be placed on the display stand as it is for display. Alternatively, the food tray 2 containing the container containing the food may be refrigerated or frozen and then used as a distribution tray that is transported in a box.

  The food tray 2 is made of a plastic material, has a rectangular outer frame portion 4 in plan view, and has three concave portions 1 formed in a line along the longitudinal direction of the outer frame portion 4.

  Examples of the plastic material include various synthetic resin materials such as polypropylene resin, polyethylene resin, polyethylene terephthalate resin, polystyrene resin, polycarbonate resin, acrylonitrile copolymer, and polyvinyl chloride resin. In addition, an inorganic filler can be mixed into these resins to increase the shape retention strength.

  The three recesses 1 are the same size and are formed in the same shape. Each recess 1 has a circular bottom wall 5, a first side wall 6 raised upward from the outer peripheral edge of the bottom wall 5, a diameter larger than the first side wall 6, and the first side wall 6. A second side wall 8 raised upward through a stepped portion 7 horizontal to the upper end of the bottom wall, and an outer surface of the lower end portion of the container placed on the bottom wall 5 on the upper surface inside the outer peripheral edge of the bottom wall 5 And a projecting portion 9 projecting upward to come into contact therewith. Therefore, at least three types of containers having different diameters can be accommodated in the recess 1 so as not to move in the recess 1. The vertical (vertical) dimension of the second side wall 8 is set to a length exceeding the vertical (vertical) dimension of the first side wall 6 (actually about four times the length).

  A tapered third side wall 10 located on the outer side from the upper end of the second side wall 8 is raised, and the vertical (vertical) dimension is set longer than that of the second side wall 8. Further, as shown in FIG. 3, the second side wall 8 is formed in a taper shape located on the outer side toward the upper end side, and the taper angle T1 of the second side wall 8 is smaller than the taper angle T2 of the third side wall 10. Is set to Thus, by providing the tapered third side wall 10, a container having a diameter larger than that of the second side wall 8 can be accommodated in the recess 1 so as not to move unexpectedly. Moreover, since it is a taper, any container of any size that fits within the taper can be securely stored in the recess 1 so that it does not move unexpectedly. Can do.

  As described above, when the outer surface of the container contacts the first side wall 6, the second side wall 8, the third side wall 10, and the protruding portion 9, it is possible to prevent the container from unexpectedly moving in the recess 1. it can. In addition, when the four side walls having different diameters are formed in the vertical direction through the three step portions by being constituted by the three side walls 6, 8, 10 and the protruding portion 9 formed in the first side wall 6. As compared with the above, the size of the recess 1 in the vertical direction can be reduced.

  A circular bulging portion 5T that bulges upward toward the center side is provided at the center portion of the bottom wall 5 (inside the protruding portion 9). The bulging portion 5T is configured with a gentle and smooth curved surface. On the other hand, as shown to Fig.6 (a), it has the rising part 21S which rises so that the lower surface of the container 21 may be located upwards so that a center part may be located. The raised portion 21S is configured with a gentle and smooth curved surface. Therefore, when the container 21 is placed on the bottom wall 5, the raised portion 21 </ b> S on the lower surface of the container 21 comes into contact with the bulging portion 5 </ b> T of the bottom wall 5, thereby causing the container 21 to move unexpectedly in the recess 1. This can be further prevented.

  The protrusion 9 is composed of a plurality of (four in this case) protrusions 9t protruding upward at a predetermined interval in the circumferential direction. The protrusions 9t are circular in plan view and have the same diameter in the vertical direction. Moreover, although the upper end of the protrusion 9t is slightly lower than the upper end of the first side wall 6, it may be the same height. Since the protrusion 9 is composed of a plurality of protrusions 9t protruding upward at a predetermined interval in the circumferential direction, there is an advantage that the material cost can be reduced as compared with the case where the protrusion 9 is formed of an annular protrusion. Here, the protruding portion 9 is formed, but the central portion of the bottom wall 5 may be recessed downward so that the container can be fixed to the recessed portion.

  As shown in FIG. 1 and FIGS. 2A and 2B, the outer frame portion 4 includes a sharpened portion 11 that becomes thinner toward the upper end side at each of the four corners at the upper end of each concave portion 1, and the sharpened portion 11. And an outer peripheral edge 12 extending outward. Among the sharpened portions 11, the sharpened portions 11, 11 adjacent to each other in the front-rear direction are connected by an arc-shaped first curved portion 13 that protrudes downward, and the sharpened portions 11, 11 adjacent in the left-right direction are connected. The two are connected by an arcuate second curved portion 14 that protrudes downward and has a smaller radius of curvature than the first curved portion 13. Further, in the concave portions 1 and 1 adjacent in the left-right direction, the radius of curvature is smaller than that of the second curved portion 14 between the front sharpened portions 11 and 11 adjacent in the left-right direction and between the rear sharpened portions 11 and 11. Are connected by an arcuate third curved portion 15 that protrudes downward.

  The outer peripheral edge portion 12 includes an annular horizontal plate portion 12A extending outward in the horizontal direction from the outer lower end of the pointed portion 11, and an annular vertical plate portion 12B hanging downward from the outer end of the horizontal plate portion 12A. And an annular outer flange portion 12C that protrudes outward in the horizontal direction from the lower end of the vertical plate portion 12B. The outer peripheral edge portion 12 formed in this way can increase the shape retention strength of the food tray 2.

  It will be described that various types of containers can be accommodated in the recess 1 of the food tray 2 configured as described above, and that 7 types of containers 16 to 22 can be accommodated in the recess 1 below.
