Description

[Detailed Description of the Invention] <Industrial application field> This invention relates to a container made of foamed resin, which has an appropriate display on the outer surface as a container for refrigerating fresh fish, raw vegetables, frozen foods and other container containers. It is designed so that it can be easily represented.

<Prior Art and Problems to be Solved by the Invention> Conventionally, as the container container, a container made of a foamed resin such as expanded polystyrene is provided because it has excellent moldability, light weight, and good heat insulation. ing. However, the container made of foamed resin has a problem that the printing characteristics on the outer surface are not sufficiently obtained.

Therefore, it has been attempted to adhere the printed strip material to the peripheral side surface of the container, but it takes a considerable amount of time to wind and remove the strip material due to the use of an adhesive agent. There is a problem in that the foamed particles forming the container are peeled off to make the container unattractive.

The present invention has been devised in view of these problems, and it is an object of the present invention to provide a container made of a foamed resin, which can be easily attached and detached to and from the display belt member in order to improve the display function.

<Means for Solving the Problems> In order to solve the above problems, the foamed resin container according to the present invention has a structure in which a banded portion including a groove step is formed along the peripheral side surface of the foamed resin container. Then, the band-shaped portion is wrapped with a display band-shaped material composed of a plurality of heat-shrinkable sheets, the ends are heat-sealed, and the heat-shrinkage is performed at each corner of the foamed resin container. It is characterized by that.

<Operation> According to the container container having the above-described configuration, the band member for display formed of the heat-shrinkable sheet is aligned and wound around the banded part formed along the peripheral side surface of the container, which includes the groove and the step. By heat-sealing the steps of the band-shaped material, and then by tightening the entire band-shaped material by heat shrinkage at a predetermined location, the band-shaped material with an appropriate indication can be attached to the peripheral surface of the container, such as grooves, steps, etc. The banded part prevents the band-shaped material from shifting downward. Then, the wound band-shaped material can be used to display the type of the packaged product in the container and the like externally.

In addition, since the band-shaped material is tightened by heat shrinkage at each corner of the container, the friction resistance at the corner of the foamed resin container is reduced and the tightening can be performed while dispersing at each corner. it can. As a result, the display strip is
It is possible to prevent the printing position from being shifted and the printing portion to be unevenly extended.

Further, since the band-shaped material for display is composed of a plurality of heat-shrinkable sheets, different displays and different colors can be easily displayed on the side surface of the container by combining various sheets.

If the type of packaged item changes and the display changes,
The non-adhesive band-shaped material can be easily detached from the container and then attached to a new band-shaped material.

<Embodiment> Next, an embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 is a container container made of foamed resin such as foamed polystyrene, 2 is a lid made of the same material as the container 1, 11 is a grooved portion formed along the outer peripheral surface of the container 1 in a groove shape, 3 is a belted portion 11
It is a heat-shrinkable sheet that is wrapped around the sheet 3.
1 is applied by printing or the like, and a transparent sheet is also preferable in that the display portion can be colored to provide a clear display, and the end portions 32 and 32 are heat-sealed, and at the corners of the container 1. The whole is tightened by heat shrinking by blowing hot air or the like. As a result, the display strip 3 can prevent the print 31 from being displaced and the print 31 to be unevenly stretched.

In practice, the foamed resin container 1 may be made of a known foamed resin other than polystyrene foam, and in any case, thermoplastic resin particles are filled in a mold to be heated and expanded to heat-bond the particles to each other. This is due to the in-mold foam molded product.

Further, as the band-shaped material 3 made of a heat-shrinkable sheet, a non-foamed film made of various thermoplastic resins such as polystyrene is suitable.

As shown in FIG. 3, the band-shaped material 3 is formed by joining two heat-shrinkable sheets by heat-sealing the end portions 32 on the short side surface of the container 1. In this way, by forming the band-shaped material 3 from a plurality of heat-shrinkable sheets, it is possible to combine different sheets and perform different display and different color expression on the side surface of the container 1 very easily.

Further, in practice, in addition to the above-mentioned groove-like portion, the belt-shaped portion 11 is formed with a step portion by a ridge provided on a flat wall surface at an appropriate interval to prevent the belt-shaped material 3 from slipping downward. Then, the upper part of the step can be used as a banded part (see FIG. 4).

In addition, protrusions may be formed at the corners as the banded portion 11 (see FIG. 5).

<Effects of the Invention> According to the container container of the present invention described above, the band-shaped member is heat-shrinkable without using an adhesive to the banded part formed by the groove, step, etc. formed along the peripheral side of the container. Since it is tightened by utilizing the property, it is easy to attach the band-shaped material, and it can be removed aesthetically without peeling off the foamed particles of the container.

In addition, since tightening due to thermal contraction of the band-shaped material is performed at each corner of the container, friction resistance at the corner of the foamed resin container is reduced and it can be performed while being dispersed at each corner. it can. As a result, the display strip is
It is possible to prevent the printing position from being shifted and the printing portion to be unevenly extended. Further, since the band-shaped material for display is composed of a plurality of heat-shrinkable sheets, different displays and different colors can be displayed on the side surface of the container by combining various sheets with extreme ease.

Further, when the strip-shaped material is being wound, it is possible to prevent the strip-shaped material from being displaced downward by the striped portion such as the groove or the stepped portion.

Therefore, it is possible to improve the display function for the foamed resin container container at the display portion displayed on the band-shaped material. Further, as described above, there is an advantage that replacement with a band-shaped material having a different display is extremely simple.
