The The main body 2 and the lid 3 are made of a synthetic resin, and are molded by, for example, vacuum molding using a molding device in which a molding die is attached to a vacuum base. Since the material of the synthetic resin, the apparatus configuration of the vacuum molding, the molding method, and the like are well-known techniques, detailed description thereof is omitted.

  In addition, the food container 1 of the present invention can contain any food such as sandwiches and rice balls, but especially cakes such as short cakes and decoration cakes that require careful handling are provided by the invention described below. It can be accommodated in good condition.

  First, as shown in FIGS. 1 to 3, the main body 2 is, for example, an appropriately colored (may be transparent) rectangular shape in plan view, and along the vicinity of the outer peripheral edge of the mounting portion 4 provided in the center. A convex portion 5 protruding upward is formed in series. The height of the upper end of the convex portion 5 is higher than the height of the upper surface 6 of the placement portion 4. In addition, when the cake is placed on the upper surface 6, the contact area between the upper surface 6 and the cake bottom is reduced so that the cake bottom does not adhere to the upper surface 6. Can be provided with any depth, shape, direction, and length. In addition, the convex part 5 is good also as a trapezoid shape by the side view which provided the gradient for the lower part toward the outer side.

  Further, a plurality of ribs 8 protruding upward are provided on the upper surface 6 of the mounting portion 4 at appropriate positions and intervals.

  On the other hand, the bottom portion of the mounting portion 4 is formed with a series of protruding portions 9 that protrude downward along the outer peripheral edge, and the lower end of the protruding portion 9 is positioned below the height of the lower surface 10 of the mounting portion 4. In addition, the outer lower end of the convex portion 5 is positioned above the lower end of the protruding portion 9.

  Furthermore, the main body side flange 11 is continuously provided on the outer lower end of the convex portion 5 along the outer peripheral edge of the outer lower end of the convex portion 5 in a continuous manner outward and in the horizontal direction. And the height of this main body side flange 11 is located above the lower end of the protrusion part 9. FIG. Further, for example, fins 12 as lock mechanisms L are continuously provided on the body side flange 11 near the center of each side of the rectangle, outward and in the horizontal direction. Therefore, the height position of the fin 12 is also located above the lower end of the protrusion 9.

  The fin 12 has a substantially ginkgo shape in plan view in which the width L1 of the portion close to the main body side flange 11 is narrower than the width L2 of the tip, and is 1 mm to 4 mm outward from the wall surface of the convex portion 5. The perforation 13 is provided in the portion of the width L1 within the range of the above, and the perforation 13 becomes the bent portion 14. And the height of the fin 12 when it folds up from the bending part 14 is made into the height of a grade substantially equal to the side wall height of the recessed part 14 in the cover body 3 mentioned later.

  The arrangement of the fins 12 is not limited to the above, and the fins 12 may be installed at a plurality of positions of at least two of the main body side flange 11. When the shape 2 is a circle, an ellipse, a triangle, a pentagon, etc., the fins 12 can be respectively provided on the body side flanges 11 at least on opposite sides and positions. However, considering the size of the container 1 (the number and weight of cakes placed on the main body 1), in the case of the rectangular main body 2 described above, the large container 1 can sufficiently withstand the weight of the cake. It is preferable to appropriately provide the fins 12 at three or four or more appropriate locations, such as providing such fins 12 on each side.

  Next, for example, as shown in FIGS. 4 to 5, the lid body 3 is a transparent dome shape having an open bottom surface, for example, a rectangular shape in a plan view, and a convex shape of the main body 2 on the inner surface of the lower peripheral portion. A concave portion 5 ′ that can be fitted onto the portion 5 is formed. Note that the concave portion 5 ′ and the side wall surface of the lid body 3 may have the same shape as that of the convex portion 5 so that the entire lid body 3 has a trapezoidal shape in side view.

  In addition, a lid-side flange 15 is continuously provided on the outer lower end of the concave portion 5 ′ along the outer peripheral edge of the outer lower end of the concave portion 5 ′, continuously outward and in the horizontal direction. When the lid 3 is fitted to the main body 2, the lid 12 on the lid side flange 15 corresponds to a position where the fin 12 is bent upward (in this example, near the center of each side of the rectangle). The locking portion 16 is formed.

  The locking portion 16 includes a bay-shaped portion 17 formed toward the inner side of the lid 3, and the entire width of the bay-shaped portion 17 is narrower than the width L 2 of the tip end portion of the fin 12, and The width L3 of the deepest portion in the portion 17 is set to a width that is slightly wider than the width L1 of the bent portion 14 of the fin 12. Further, a flat space is provided on the lid-side flange 15 on both sides of the bay-shaped portion 17 as a latching portion 18 that latches both ends of the fin 12.

  Further, on both sides of the hooking portion 18, between the upper surface of the lid-side flange 15 and the wall surface of the concave portion 5 ', a reinforcing bridge 19 is formed by bridging both. Further, a concave gripping portion 20 is dug and formed on the top surface of the lid 3 symmetrically with respect to the center portion. Reference numeral 21 denotes a reinforcing portion that is appropriately formed on the lid 3.

  And the holding | grip part 20 mounts a cold insulating agent etc. in the space s near the both ends of this holding | grip part 20 by digging and forming long in the width direction (it is not limited to the longitudinal direction in a figure) of the container 1. And the preservation state of the food stored in the container 1 can be improved. Therefore, the container 1 of the present invention is formed by digging and forming the grip portion 20 and the space s for placing the cold insulation agent integrally on the upper surface of the lid 3 and is excellent in productivity and usability. is there.

  Here, when accommodating a cake in the container 1 provided with two or more pairs of the lock mechanisms L including the fins 12 and the hooking portions 18 as described above, first, one or more cakes are placed. The main body 2 is placed between the ribs 8 on the upper surface 6 of the placement portion 4. For this reason, even when the container 1 rolls during transportation or the like, since the cake is substantially fixed by the ribs 8, it is possible to prevent the cake from moving in the horizontal direction and to hold the placement position of the cake. Therefore, the cake can be prevented from being damaged due to the falling of the cake.

  Next, the concave portion 5 ′ of the lid body 3 is placed on the convex portion 5 of the main body 2, and the lid body side flange 15 is placed on the main body side flange 11, and the lid body 3 is fitted to the main body 2.

  Next, as shown in FIGS. 6 to 7, the fin 12 is folded upward along the perforation 13 of the bent portion 14. At this time, since there is a gap between the fin 12 and the lower end of the protruding portion 9, the tip of the fin 12 can be easily sandwiched with fingers, and the fin can be efficiently used in work on a flat desk. 12 can be folded up.

  Further, since the fin 12 has the width L1 of the bent portion 14 near the main body side flange 11 narrower than the width L2 of the front end portion, the bent position of the fin 12 is easily understood and the fin 12 can be bent easily. be able to.

  Further, since the bent portion 14 of the fin 12 is a perforation 13, once the fin 12 is bent, the fin 12 is easily held near the folding position via the perforation 13, and the position before the fin 12 is folded up. The fin 12 can be kept folded by a single bend.

  And since the perforation 13 of the fin 12 is provided in the range of 1 mm-4 mm toward the outward from the wall surface of the convex part 5, the folded-up fin 12 is the wall surface of the concave part 5 'of the cover body 3 The fins 12 can be reliably locked to the locking portions 16 by being aligned with each other.

  Next, the both end portions of the fin 12 are moved along the both ends of the bay-shaped portion 17 of the locking portion 16 and pushed into the bay-shaped portion 17 with a light force. It is latched by latching portions 18 located on both sides of the bay-shaped portion 17. As a result, each fin 12 is latched by the latching portion 18 and securely fixed, so that the operator does not need excessive force, and the lid 3 can be easily fixed to the main body 2 simply by folding up the fin 12. In addition, the lid 3 is not easily detached from the main body 2 by the strong fixation between the fins 12 and the locking portions 16, and the cake can be accommodated in the container 1 with peace of mind.

  Further, the container 1 can be easily lifted and transported by holding the grip portion 20 on the upper surface of the lid 3 with a finger and lifting the lid 3. At this time, a downward load is applied to the fins 12 on the hooking portion 18 due to the weight of the cake on the mounting portion 4, but the strength of the hooking portion 18 (lid body side flange 15) is improved by the bridge 19. Therefore, the fins 12 are not deformed, and the detachment of the fins 12 due to the deformation of the latching portions 18 and the fins 12 can be prevented, and the fins 12 can be securely latched to the latching portions 18.

  Contrary to the above, when taking out the stored cake from the container 1 in which the lid 3 is fitted and fixed to the main body 2 by the lock mechanism L, first, the latching portion 18 is provided inside the bay-shaped portion 17. Lightly push down the vicinity of the tip end portion of the fin 12 hooked on the outside with the finger toward the outer side of the lid-side flange 15 and in the horizontal direction.

  Thereby, the both ends of the fin 12 move along the inside of the bay-shaped portion 17, the fin 12 is detached from the bay-shaped portion 17, and the fin 12 is positioned on the lower surface of the bay-shaped portion 17. As a result, the lid 3 can be easily released from the fixing of the main body 2, and the lid 3 can be easily detached from the main body 2. Therefore, when the lid is removed by applying excessive force in the same manner from a container in which the main body and the lid are forcedly applied to each other through a joint as in the prior art, the container is shaken. It will not damage the cake if it is moved. That is, when the lid 3 is opened, the container 1 does not swing due to easy release of the lid 3 and the main body 2 by the lock mechanism L, and the cake on the main body 2 can be taken out in a good state.

  In addition, the fin 12 can be bent many times as described above, and the fin 12 can be attached to and detached from the hooking portion 18 many times. Therefore, the cake can be taken in and out many times, and the container 1 can be used effectively. Can do. Since the top surface of the lid 3 can be fitted into the lower surface of the mounting portion 4 surrounded by the protruding portion 9 at the bottom of the main body 2, other containers are stably stacked on the container 1. be able to.

  The lock mechanism L described in detail above is made of the same material as that of the main body 2 and the lid body 3, and the main body 2 and the lock mechanism L (fin 12) can be formed at the same time when the container 1 is produced. Since the mechanism L (locking portion 16) can also be molded in a lump, the main body 2 for fitting the lid 3 to the main body 2 and a member different from the lid 3 are formed on the main body 2 and the lid 3. The container 1 can be efficiently formed without having to be attached in a separate process. Similarly, the gripping portion 20 and the like can be collectively provided at the time of forming the lid body 3 as described above.

  As described above, the shape of the container can be circular. FIG. 8 is a plan view (a) and a side view (b) of a main body showing an example of a circular food container, and FIG. 9 is a plan view (a) and a side view of a lid showing an example of a circular food container.
