Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tray and a packaging structure used for packaging food such as seafood, vegetables and fruits.

[0002]

[Prior Art]

 Generally, flat and rectangular trays are used for packaging foods such as seafood.

As shown in FIG. 5, a conventional tray 1 is formed by integrally molding a synthetic resin material and is formed into a flat shape in a substantially rectangular shape, and has a slightly deep annular drainer between a side wall portion 2 and a bottom portion 3. It is formed in a shape provided with the portion 4. In addition, a tray having a shape without the draining section 4 is also used.

When actually used, as shown in FIG. 6, a thin liquid absorbing member 5 is laid on the bottom portion 3, a food material 6 with a lot of drip such as fish is placed thereon, and The packaging film member 7 was used to wrap the tray 1 so as to cover the entire outer periphery thereof.

The food material 6 thus packaged is displayed on a display shelf or the like, and the liquid that has exuded from the food material 6 is absorbed by the liquid absorbing member 5.

[0006]

[Problems to be solved by the device]

 However, in the conventional tray 1, since the bottom portion 3 is formed in a planar shape over the whole, the liquid that has exuded from the food material 6 spreads over the entire bottom portion 3 of the tray 1 and the food material 6 The entire bottom surface comes into contact with the liquid, and the freshness decreases faster. Moreover, since most of the liquid absorbing members are paper and non-woven fabric-like materials, there is a limit to the absorption of drip. In addition, since the liquid inside the packaging film member 7 was seen to spread over the entire tray 1, the appearance was poor and the commercial value was poor. Further, although the liquid absorbing member 5 is relatively expensive, in the conventional example, the liquid absorbing member 5 needs to be laid on the entire surface of the bottom portion 3 of the tray 1, resulting in high cost. Further, since the liquid absorbing member 5 expands when absorbing the liquid, the whole food material 6 is lifted up and pressed against the packaging film member 7 so that the food material 6 is crushed, further reducing the commercial value. It was something that caused it. Further, since the bottom 3 of the conventional tray 1 is entirely formed in a flat shape, the fingers do not go down when trying to lift it when performing a display work or the like, so the work efficiency is poor. was there.

The present invention has been made in view of these points, and has a high ability to retain the freshness of packaged foodstuffs, and it is possible to keep the liquid that has exuded from the foodstuffs invisible from the outside, thus increasing the commercial value. It is an object of the present invention to provide a tray and a packaging structure which can be made extremely high and can be manufactured at low cost.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the tray according to the present invention according to claim 1 is a tray which is formed by a sheet member in a shape that is opened upward. It is characterized in that it is formed by a gradually shallower portion that gradually becomes shallower toward the end.

Further, the tray of the present invention according to claim 2 is characterized in that a liquid absorbing member is attached to the flat surface portion of the bottom portion.

According to the packaging structure of the present invention described in claim 3, the article to be packaged is contained in the tray according to claim 2, and the opening of the tray is hermetically packaged by a packaging film member. Characterize.

[0011]

[Action]

 By packaging foodstuffs using the tray of the present invention, the freshness of the packaged foodstuffs can be kept high for a long period of time, and the liquid that has exuded from the foodstuffs is protected by a liquid absorbing member. It can be absorbed and the product value can be significantly increased.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

1 to 3 show one embodiment of the tray of the present invention, and FIG. 4 shows one embodiment of the packaging structure of the present invention.

As shown in FIGS. 1 and 2, the tray 11 of the present embodiment is formed by integrally forming a synthetic resin material and is formed in a flat shape in a substantially rectangular shape, and is formed by a side wall portion 12 and a bottom portion 13. Has been done. The bottom portion 13 has a deepest flat surface portion 13a at a central portion in the longitudinal direction, and gradually shallower portions 13b and 13b (inclined surfaces in the present embodiment) that are gradually shallower from the flat surface portion 13a toward both ends of the tray. It is formed by. The bottom portion 13 and the side wall portion 12 formed in this manner are formed to be continuous by a curved surface.

Further, as shown in FIG. 3, the tray 11 is configured such that the liquid absorbing member 14 is attached to the upper surface of the flat surface portion 13 a of the bottom portion 13 for use.

Next, referring to FIG. 4, the packaging structure of the foodstuff 15 which is one type of the article to be packaged will be described.

First, the liquid absorbing member 14 is placed on the flat surface portion 13a of the bottom portion 13 of the tray 11, and then the food material 15 is placed on the liquid absorbing member 14 and the gradually shallowing portions 13b and 13b. Next, the food material 15 and the tray 11 are wrapped together by the packaging film member 16 for packaging.

According to such a packaging structure, the liquid that has exuded from the food material 15 flows over the gradually shallowing portions 13b, 13b of the bottom portion 13 of the tray 11 and collects at the deepest flat surface portion 13a in the center, and the liquid absorbing member. Is absorbed by 14.

Therefore, since the portions of the food material 15 on the gradually shallower portions 13b and 13b do not come into contact with the liquid, the freshness is kept high. Further, since all the liquid exuded from the food material 15 is absorbed by the liquid absorbing member 14 at the deepest flat surface portion 13a, the liquid cannot be seen at all even from the packaging film 16. Therefore, the appearance as a packaged product is extremely excellent.

Further, although the liquid absorbing member 14 absorbs the liquid and expands, since the liquid absorbing member 14 is not present on the gradually shallow portions 13b and 13b, the packaging film member 16 has a central portion in the longitudinal direction. It is appropriately spread by the lifted foodstuffs 15, and the foodstuffs 15 have high commercial value without being pressed by the conventional foodstuffs.

In addition, since a space into which a finger can enter is formed below the gradually shallowing portions 13b and 13b of the bottom portion 13 of the tray 11, it is easy to lift when performing display work and the work efficiency is very good. It is a thing.

Further, the size of the liquid absorbing member 14 can be reduced to the size of the flat surface portion 13a which is about 1/3 of the size of the bottom portion 13 in the present embodiment, which reduces the manufacturing cost. be able to.

In the above embodiment, the gradually shallowing portions 13b and 13b of the bottom portion 13 are inclined surfaces. However, any shape may be used as long as it is a shallow surface such as a curved surface. Further, the planar shape of the tray 11 may be formed in other shapes such as a rectangular shape and a circular shape other than the rectangular shape.

It should be noted that the present invention is not limited to the above-described embodiment, but can be modified as necessary.

[0025]

[Effect of the device]

 As described above, since the tray and the packaging structure of the present invention are constructed and function, the freshness of the packaged foodstuffs can be kept high, and the liquid exuded from the foodstuffs can be hidden from the outside. Can be remarkably increased, and the manufacturing cost can be reduced.
