JP 2003-191937 A

  An object of the present invention is to obtain a packaging container that can be used as a substitute for washing with water and can be used as it is.

In the packaging container of the present invention, a plurality of drain holes are provided in the peripheral wall of the container main body provided with a recess for storing articles, and the upper surface of the bottom wall of the recess is configured as a downwardly inclined surface from the central portion toward the peripheral portion. There is no limitation on the shape of the drain hole.
A second aspect of the invention is a packaging container comprising a container body and a lid body configured as in the first aspect, wherein the lid body is provided with a plurality of drain holes, and the invention of the third aspect is an article. Both the top of the bottom wall of the recess for storage and the top of the top wall of the lid (the top when the container body is covered) are convex in cross section, and when the bottom wall of the container body and the top surface of the lid are overlapped According to the invention of claim 4, which is fitted to each other, the main body of the packaging container and the lid are connected to each other, and a perforation for cutting is provided in the connecting portion.
In each of the above inventions, it is preferable in terms of production that the drain hole of the recess has a structure in which a step portion is provided on the peripheral wall of the recess for storing articles and a vertically long drain hole is provided above and below the step portion. Moreover, it is preferable to provide in the valley of the standing rib.

The material, size, and shape of the container are appropriately selected in consideration of the relationship with the stored items. In addition, the specific shape, size, position, and number of the drain holes are determined as appropriate, but it is preferable to obtain an opening that is as wide as possible while maintaining a size that does not damage the contents.
The form of the bottom surface of the container main body can be appropriately selected such as a quadrangular pyramid shape or other polygonal pyramid shape in addition to a circular arc shape in cross section. In short, any configuration may be used as long as the water on the bottom surface flows to the peripheral portion.
When the packaging container is composed of a main body having a recess for storing articles and a lid, it is preferable to provide a plurality of drain holes in the lid. The lid may be a separate body from the main body or may be a continuous one.

According to the present invention, since the drain hole is provided in the peripheral wall of the recess, the contents can be washed with water by using the packaging container as a substitute for draining. Moreover, since these drain holes become air passage holes during distribution, they contribute to maintaining freshness.
In addition to the above, since the bottom surface is a downward inclined surface directed from the central portion toward the periphery, water adhering to the fruit or the like accumulates at the peripheral portion. As a result, the lower storage item is prevented from being immersed in water.
As described above, the packaging container of the present invention can be used as a substitute for washing without water and can be placed on the table as it is.
Furthermore, in the invention of claim 2, since the drainage hole is also provided in the lid combined with the container body, the lid can be closed after washing with water and drained from the lid for efficient drainage. In the invention of claim 3, since the container body and the lid are fitted to each other, they can be stacked in a stable state, and the lid can be used as a tray.

Examples of the present invention will be described below.
The packaging container 1 is made of a synthetic resin sheet, and is composed of a main body 2 and a cover body 3 each having a storage concave portion that is rectangular in plan view. The main body 2 and the cover body 3 are flanges of an opening. The perforation 4 is provided in the continuous part.

The main body 2 includes a bottom wall 5 and a peripheral wall 6.
The bottom wall 5 includes a raised portion 7 having a convex arc shape in cross section, and is inclined downward from the central portion toward the peripheral portion, and an annular groove 8 is formed in the peripheral portion. The width of the groove 8 is such a size and shape that the stored item A does not fit into the groove (the stored item does not contact the bottom of the groove).
The peripheral wall 6 of the main body 2 is inclined upward and has an outward step portion 9 at the lower portion, and a plurality of vertically long drain holes 10 are provided above the step portion 9. is there.
Inward ribs 11 are provided between adjacent drain holes 10. The interval and the size of the adjacent ribs 11 are set so that the stored item does not contact the drain hole 10.

  A plurality of vertically long drain holes 12 are also provided on the peripheral wall of the lid 3. The drain hole 12 may be provided in the top wall 3 a of the lid 3. Moreover, the upper surface (upper surface when the lid is closed) of the top wall 3a of the lid body 3 has a convex arc-shaped portion 13 in cross section, and the convex arc-shaped portion 13 is connected to the raised portion 7 of the bottom wall 5 of the container body. The shape and size fit.

Hereinafter, the use of this packaging container will be described by taking as an example the case of use for packaging of cherry tomatoes.
The producer of cherry tomatoes stores cherry tomato A in a packaging container 1 in the same manner as a conventional container, and packages and ships it. In the packaged state, the drain holes 10 and 12 of the main body 2 and the lid 3 function as air circulation holes.
Further, since the groove 8 is provided in the bottom wall 5 and the width of the groove 8 is such that the stored item does not come into contact with the bottom of the groove, the cherry tomato A located at the peripheral edge of the bottom wall floats from the bottom wall. It becomes the state. Conventionally, cherry tomatoes located at the peripheral edge are easily damaged because they are sandwiched between the bottom wall and the collecting wall and pressed.
Furthermore, since the recessed part formed by the protruding part 7 of the container main body 3 and the convex arc-shaped part 13 of the lid body are fitted, a plurality of containers can be stacked in a stable state.

A consumer who has purchased the cherry tomatoes packaged in this container opens the lid 3 and rinses the cherry tomatoes with the cherry tomatoes in the main body 2. Next, the lid 3 is closed and drained. By closing the lid 3 and draining water, there is no possibility that some cherry tomatoes will escape from the main body. Moreover, since the drainage hole 12 is provided also in the cover body 3, it can drain efficiently even in the state which closed the cover body.
Since the inward ribs 11 are provided on the peripheral wall 6 so that the cherry tomatoes do not contact the drain holes 10, there is no possibility that the surface of the cherry tomatoes touches the edge of the drain holes and is damaged.

After draining, the lid 3 is torn along the perforation 4, and the water adhering to the outer surface of the main body 2 is wiped off and placed on the table. At this time, the container main body 3 can be placed in a stable state as a lid and a tray by fitting the convex arc-shaped portion 13 of the lid 3 into the concave portion of the bottom wall of the main body 2.
Even after draining, the cherry tomatoes still have moisture, which gradually moves downward. Part of the water that has moved downward directly reaches the groove 8 and part of the water reaches the raised portion 7. Since the upper surface of the raised portion 7 is inclined downward toward the groove, the water on the upper surface of the raised portion gradually reaches the groove 8.
In this way, water adhering to the cherry tomato is stored in the groove 8. Here, since the size and shape of the groove 8 are such that the cherry tomatoes do not come into contact with the groove bottom, the cherry tomatoes are not immersed in the water accumulated in the groove.
Further, if the lower end of the drain hole 10 is set slightly above the upper surface of the bottom wall, the water accumulated in the groove does not flow out of the drain hole 10. Moreover, even when the lower end of the drain hole is in contact with the bottom wall, the table does not get wet by using the lid 3 as a tray.

  This invention provides great convenience when eating fruits as well as when fruits are distributed, and has industrial applicability.
