Description

[Detailed description of the invention] <Industrial application field> This invention mainly involves putting meat, fruits, fish, and other foodstuffs into a dish-shaped packaging container, and covering the upper surface of the container with a transparent thin film for food packaging. (Wrap film for food packaging) (hereinafter referred to as wrap film) is a container used for packaging, etc., and is mainly used in production areas and packaging plants for the above foodstuffs.

<Prior art> Conventional food packaging containers of this type are dish-shaped with an open top. Fresh food, such as meat, is placed in the dish-shaped container, and the entire container is covered with a wrap film from above. It was wrapped.

<Problems to be solved by the invention> However, in this conventional packaging form, the wrap film is wrapped directly and in close contact with the food, and this contact surface quickly discolors, reducing the freshness of the food. It has the disadvantage that it tends to reduce the quality of food, and at the same time, it has significantly reduced the desire to purchase it as a fresh food. In addition, wrap film was also used to package vegetables and fruits such as eggplant and cucumber in sealed packaging.

As a means to solve these problems, a conventional dish-shaped container is made of foamed plastic material, and protrusions with vertical grooves formed on both opposing bases of the bottom wall are formed integrally with the container. It has already been proposed that the movement of stored items is prevented by using flexible protective bands formed separately from the storage devices and inserting both ends of the bands into these vertical grooves. (Refer to Utility Model Publication No. 58-46972.) However, in this proposed known container, since the protrusion is formed integrally with the container,
It is difficult to form plastic sheets, which are inexpensive and easy to mold, and requires the use of injection molding, making mass production not as easy as with sheet molding, and expensive. Moreover, it is necessary to separately form a flexible protective band to prevent the stored items from moving, which increases costs.Furthermore, when using these containers, It was not possible to eliminate the trouble of having to align the belts and inserting and locking both ends of the belt into vertical grooves formed in the protrusion of the container. .

Therefore, the inventor of the present invention has focused on such drawbacks, and has developed the above-mentioned method without complicating the structure in manufacturing or making it extremely troublesome in use. We have devised a container that can eliminate the conventional drawbacks and propose it here.

<Means for Solving the Problems> To explain the structure of the present invention using FIGS. 1 and 2, which show examples, the food packaging container referred to in the present invention is a dish-shaped container for food packaging. In A,
A band-shaped body 2 is formed integrally and continuously from a part 1a of the peripheral wall 1, and a bent part 6 is formed at the base end portion of the continuous body,
The length of the band-shaped body 2 is formed to a length that can be bridged from the continuous peripheral wall portion 1a to the opposing peripheral wall portion 1b, and the free end portion 2a of the band-shaped body 2 is connected to the opposing peripheral wall portion. This is a molded container made of a synthetic resin sheet material that is formed into a structure that can be locked to 1b.

<Function> Fresh food, for example, meat B is placed in the dish-shaped container A thus formed, and the strip 2 is passed over the meat B so that the notch engaging portion 4 provided at the free end 2a is inserted into the container. The container A is engaged with a cutout engagement portion 5 formed on the opposing peripheral wall portion 1b of the container A, and a wrap film 3 is hung from above the band 2 to enclose the container A as a whole. Furthermore, in the case of vegetables and fruits such as cucumbers and eggplants, it is not necessarily necessary to use a wrap film, and it is possible to use the wrap film only by securing the strip.

<Example> An example of the present invention will be described based on FIGS. 1 and 2. A dish-shaped molded container of an appropriate depth (depth or shallowness does not matter) without an upper lid formed by a blow molding method,
As shown in FIG. 2, strips 2, 2 are continuously molded outward from two locations on one circumferential wall 1a of the flange circumferential wall 1 formed on the upper outer circumferential surface. The free end portion 2a is formed to have a length sufficient to form a bridge when the continuous peripheral wall portion 1a is placed in a bridging posture as shown in FIG. 1 toward the opposing peripheral wall portion 1b. There are small U-shaped notch engaging portions 4 at three locations facing each other on both sides of the side...
, and dovetail cut locking portions 5, 5 are formed on the opposing peripheral wall portion 1b. Reference numerals 6 and 6 shown in FIG. 2 are bending grooves formed concavely downward to facilitate bending of the strips 2, 2.

When using this container A, as explained in the section of the above-mentioned function, raw meat B, which is an example of fresh food, is put therein, and the above-mentioned notch engaging portion 4 is placed in a cross-linked manner above the strips 2, 2. Cut the locking part 5,
5, and wrap film 3 from the top surface.
Then, the whole container A is covered.

The embodiments shown in FIGS. 3 and 4 are different embodiments, and the embodiment shown in FIG. Triangular notch engaging portion 4 on side 2a...
A long hole locking portion 5 is formed in the opposing peripheral wall portion 1b, and the free end portion 2a of the band-shaped body 2 is inserted into the long hole 5 and engaged and locked at the notch engaging portion 4. In the embodiment shown in FIG. 4, the engaging portion 4 of the band-shaped body 2 has a long hole shape, and the opposing peripheral wall portion 1b
The locking portion 5 is formed in the shape of a protruding tongue that projects into the elongated hole.

5 to 8 show examples of the structure and shape of containers according to the present invention, and the one shown in FIG. ′, the strips 2, 2, 2,
2' and 2' are alternately shaped. In this case, both strips 2... are positioned slightly to one side from the center line, that is, the container A on the left side in the figure is Below, the container A' on the right side is a container A with strips 2... placed in series at a position slightly deviated upward.
A′ can be obtained. In the figure, 6 and 6' indicate perforations formed to facilitate bending. 6th
In the embodiment shown in the figure, the shapes of the strips 2, 2, 2' of the left and right containers A and A' are different, and the left container A has two strips 2, 2 with the center line in between. ,
The container A' on the right side has a structure in which one strip 2' is formed in series only in the center. In the embodiment shown in FIG.
By forming them in a continuous manner in an inclined direction with respect to A', it is possible to obtain a container that can be bridged in an inclined position on the upper surfaces of containers A and A' even during use. In the embodiment shown in FIG. 8, when forming the left and right containers A and A' at the same time, the band-shaped body 2...
This figure shows a structure in which the left and right containers are formed with a phase shift in the longitudinal direction by the width of the container.

Although the embodiments of the structure considered to be representative of the present invention have been shown above, the present invention can be implemented as follows.

One or more strips 2 may be provided for one container A, and the number, width, etc. may be arbitrarily selected.

The band-shaped body 2 may be secured using a cellophane tape coated with an adhesive, a stapler, or the like.

The band-shaped body 2 may be flat when not in use, or may be formed into an arc shape in advance when forming the container.

It can be conveniently used if necessary information such as the product name, manufacturer's name, production date, etc. are printed so that they can be seen from the upper surface side when the belt-shaped body 2 is used, or from the back side to the upper surface side.

The shape of the container A is not limited to a rectangle, but may be a square or other shape, and the direction in which the band-shaped body is formed is not limited to the short width direction of the container.
It may also have a structure that is crosslinked in the longitudinal direction.

It is convenient to have a plurality of engaging parts 4 formed on the band-shaped body 2 in the case of a container for multi-purpose use, but it is sufficient to form one engaging part 4 in the case of a container for single-purpose use.

Furthermore, it goes without saying that the present invention can be modified and used as appropriate within the scope of having the constituent features described in the present invention, achieving the purpose described in the present invention, and having the following effects.

<Effects of the invention> As explained above, the present invention eliminates the drawbacks of containers with lids that require a large amount of materials and cannot prevent the movement of the product inside the container when the product is placed in the container. Targeting dish-shaped containers,
After putting fresh food in it, a band is used to lock it so that it does not fall. Fresh vegetables can be used as is, and in the case of meat, the wrap film can be inserted from above. Since it can be used to cover the entire container, the freshness of the packaged food can be seen from the outside in any case, and in the case of meat and fish, Since the wrapped film does not come in direct contact with the product, it has the advantage of being able to eliminate the drawback that the contact area of the film is likely to discolor, which significantly reduces the desire to purchase.

In the case of the present invention, in particular, the container body and the band-shaped body are integrally formed using a synthetic resin sheet material, and a bent part is formed at the base where these are connected. Since it is easy to mold and can be molded in one piece, there is no need to search for the strip when using it, and the strip can be folded and immediately secured only at its tip, so it can be packaged quickly. It also has the advantage of being able to
