Abstract

PROBLEM TO BE SOLVED: To obtain a simple container on which a certain indication can be given and in which a deformation does not occur even if hot water is poured by a method wherein an uneven outer packaging paper is wrapped around a trunk, and a part of the paper in which a machine-readable indication is formed is made flat. SOLUTION: An outer packaging paper 20 is wrapped around the external surface of a trunk part 10, and spaces are formed between the outer packaging paper 20 and the trunk part 10 by protuberances 22 projecting to the inside of the outer packaging paper 20, and thereby a heat-insulating property is imparted to the trunk part 10. Furthermore, spaces are formed by protuberances 21 on the external surface of the outer packaging paper 20 between the outer packaging paper 20 and fingers when held by a hand, and thereby a container can be held by hand without giving a feel of heat. Namely, an excellent heat- insulating property is imparted to the container by the outer packaging paper 20 having the protuberances 21 and 22. Since a bar code 24 is indicated at a flat part 23 of the outer packaging paper 20, reading by a bar-code reader becomes possible and control of physical distribution can be surely effected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple container, and more particularly to a disposable simple container mainly made of paper.

[0002]

2. Description of the Related Art Simple containers are widely used for supplying instant beverages and instant foods. The simple container is, for example, a cup-shaped container made of paperboard, and is filled with a beverage or food and supplied.

On the other hand, as a simple container for instant noodles into which hot water is poured for edible use, a simple container made of expanded styrene resin is widely used. This is because when hot water is poured, the body becomes hot, so that heat insulation is required. That is, the container of the styrofoam resin has a heat insulating property that meets the above requirements.

[0004]

DISCLOSURE OF THE INVENTION Insulated containers made of expanded polystyrene have the potential to produce black smoke when incinerated after use, or to damage the furnace due to high heat, and are discarded containers. There is a problem that causes pollution. Therefore, for example, Japanese Utility Model Registration No. 2520712 proposes a heat insulating container in which a heat insulating sheet made of single-sided cardboard is wound around the outer peripheral surface of the body with the liner inside. In such a container, heat insulation is imparted to the container by a single-sided cardboard adhered to the outside, but beautiful printing cannot be performed on the outer surface by the step. Even if a barcode is displayed on the outer surface, there is a problem that reading with a barcode reader becomes impossible or reading becomes difficult due to unevenness of the steps.

[0005] In a simple container having a double trunk portion, if hot water is poured into the simple container, the air in the intermediate portion of the double structure expands rapidly, which causes a problem that the container is deformed. Further, even in the case of the double structure, if the thickness of each portion is small and does not have sufficient strength, the required rigidity may not necessarily be exhibited.

[0006] The present invention has been made in view of such problems, and can provide a required display, does not deform even when hot water is poured, and has a required rigidity. It is an object of the present invention to provide a simple container which can be provided with a simple container.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to provide a disposable simple container made of paper as a main material, wherein an exterior paper having irregularities is wrapped around a body portion. The present invention relates to a simple container characterized by having a flat surface without forming irregularities in a portion for forming a display which is read by the method. Here, a barcode read by a barcode reader may be displayed on a flat surface.

According to another aspect of the present invention, in a disposable simple container made of paper as a main material, an exterior paper having a protruding portion formed intermittently so as to protrude inward is wound around a body portion, The present invention relates to a simple container, wherein a space for providing heat insulation is formed between a body part and an exterior paper by the projection.

Here, the area ratio of the projections on the outer paper may be 20% or less, more preferably 25% or less. In addition, the size of the protrusion on the exterior paper may be 以下 or less, more preferably １ ／ or less of the interval between the protrusions. The protrusion may be a substantially hemispherical protrusion having a diameter of 6 mm or less, more preferably 5 mm or less.

As described above, the area ratio of the protrusion on the outer surface is 20% or less, or the size of the protrusion is 1/2 or less of the interval between the protrusions, or the diameter of the protrusion is 6%.
mm or less, by making it a semi-spherical projection,
The protrusions on the exterior paper are less noticeable, which makes it possible to perform beautiful printing and display on the surface of the exterior paper.

[0011] Further, if a structure is adopted in which a small hole is formed in the projection and the inside and outside of the exterior paper are communicated with each other by the small hole, the body and the exterior paper when hot water is poured into the container are formed. The deformation of the container due to the expansion of the air in the space between them is prevented.

[0012] Still another aspect of the present invention is a disposable simple container mainly made of paper, in which a glue or an adhesive is applied in a streak shape on the outer surface of the body, and the exterior paper having irregularities is provided on the body. The present invention relates to a simple container characterized by being wrapped around a part. Here, the glue or adhesive may be applied on the outer surface of the barrel in a longitudinally streaked manner, or the glue or adhesive may be applied on the outer surface of the barrel in a spiral and streaked manner. . Such a streaky glue or adhesive makes it possible to impart sufficient rigidity to the container.

[0013] A preferred embodiment of the present invention is that the outer paper, in which protrusions protruding outward and protrusions protruding inward are alternately formed, is wound on the outer surface of the body of a simple cup-shaped simple container. The simple container is provided with a heat insulating property by a protrusion projecting inward and outward. Here, a flat portion is formed at a predetermined position of the exterior paper, and a barcode is formed on the flat portion, so that the barcode can be read by a barcode reader.

In another preferred embodiment of the present invention, an exterior paper having intermittent projections projecting inward is wound around the outer surface of the body of a simple container formed in a substantially cup shape. . Here, the protrusions on the outer packaging paper have an area ratio of 20% or less, the size of the protrusions is 1/2 or less of the interval between the protrusions, and each protrusion has a substantially hemispherical shape with a diameter of 6 mm or less. The projections may form beautiful prints on the surface of the exterior paper. Also, if a small hole is formed at the bottom of the projecting portion that protrudes inward, even if the air in the space between the trunk and the outer packaging paper expands when hot water is poured into the container, it expands. The air can escape to the outside through the small holes, thereby preventing deformation of the container.

Prior to winding such an outer paper, a glue or an adhesive is applied in advance to the body of the container in a longitudinal or spiral streak, and the outer paper is wound in such a state. When attached, it becomes possible to give high rigidity to this container by the solidified glue or adhesive, and the container is hardly deformed. Further, from this, the thickness of the container body or the exterior paper can be reduced, thereby reducing the cost.

[0016]

1 to 4 show a simple container according to a first embodiment of the present invention. This simple container has a substantially cup shape. In other words, by winding the fan-shaped base paper, a simple container having a body portion 10 having a substantially cup shape is formed. The periphery of the upper opening 11 of the body 10 is rolled outward to form a curled portion 12.

On the other hand, the lower end of the body 10 is closed by a bottom plate 13. The peripheral wall portion 14 on the outer peripheral side of the bottom plate 13 is bent downward, and such a peripheral wall portion 14 is sandwiched between the lower end of the body portion 10 and the folded portion 15 so that the bottom plate 13 is connected to the lower end of the body portion 10. It can be attached to.

In order to provide heat insulation to such a container, particularly to the body portion 10, an exterior paper 20 as shown in FIG.
Is wound. The exterior paper 20 is made of paperboard, and as shown in FIG. 4, outwardly projecting protrusions 21 and inwardly projecting protrusions 22 are formed alternately in a staggered manner and adjacent to each other. I have.

At a predetermined position of the exterior paper 20,
A substantially rectangular flat portion 23 is formed, and a bar code 24 is displayed on the flat portion 23. Then, as shown in FIG. 1 and FIG. 2, such an exterior paper 20 is wound on the outer surface of the body 10 of the simple container.

Such a simple container is used to supply hot beverages. Alternatively, it is used for supplying beverages and foods that require pouring hot water when eating and drinking. For example, it is used as a container for instant noodles or cup noodles.

When used as a container for instant noodles or cup noodles, pour boiling water into the container while the noodles are contained, leave the noodles for a few minutes, and then eat the noodles in this container. I have.

Here, the exterior paper 20 is wound around the outer surface of the body 10, and a space 25 is formed between the exterior paper 20 and the body 10 by the protrusion 22 projecting inward from the exterior paper 20. That is, such a space 25 causes the trunk 10
Is given heat insulation. Alternatively, a space is formed between the finger and the exterior paper 20 when held by hand by the outwardly projecting protrusion 21 on the outer surface of the exterior paper 20 of the container, whereby the container can be felt without feeling heat. It is possible to have. In other words, the exterior paper 20 having the projections 21 and 22 imparts high heat insulation to the container.

Further, since the bar code 24 of the packaging paper 20 of such a container is formed on the flat portion 23, the bar code reader cannot be read by the bar code reader due to the projections 21 and 22 for heat insulation, or the bar code is not read. There is no error, and the management of the physical distribution can be performed reliably.

Next, another embodiment will be described with reference to FIGS. In this embodiment, only an inwardly projecting projection 22 is formed on the exterior paper 20, and no outwardly projecting projection 21 is formed. Also, here, the size of the protrusion 22 is reduced, and the size of the protrusion 22 on the exterior paper 20 is reduced, so that it is not noticeable. With such protrusions 22, it is possible to perform beautiful printing on the exterior paper 20, and it is possible to perform various displays that do not make the presence of the protrusions 22 feel. Also here, the bar code 24 has the flat portion 23 where the projection 22 is not formed.
Are displayed, thereby avoiding a reading error of the barcode 24 or an unreadable state.

In this embodiment, the outer paper 2
A small hole 30 is formed at the bottom of the protruding portion 22 which is convex toward the inside as shown in FIG. 8 and FIG. When such a small hole 30 is used for a container for cup noodles,
When the hot water is poured into this container, the exterior paper 20 and the body 1
This is for preventing deformation of the container when the air in the space 25 between 0 and 0 is rapidly expanded. Even if the air in the space 25 expands, the expanded air is radiated to the outside through the small holes 30 of the protruding portion 22 of the exterior paper 20, thereby reliably preventing deformation of the container. .

Such a container is used for supplying cup noodles and high-temperature beverages. And the exterior paper 2 of such a container
The space 22 formed between the exterior paper 20 and the body 10 by the protrusion 22 of 0 gives heat insulation to the container, and the user feels heat even when holding the container by hand. There is no. Further, the bar code 2 is formed by the flat portion 23.
4 can be accurately read by the barcode reader,
Distribution management is ensured. The small holes 30 formed in the bottom of the protrusion 22 of the exterior paper 20 allow the space 2 to be formed.
When the air in 5 expands, the expanded air can be released. Therefore, even if you pour boiling water into this container,
Deformation of the container is avoided.

Here, the protrusion 2 on the exterior paper 20 is used.
The area occupied by 2 is about 10%, and the size of the protrusion 22 on the exterior paper 20 is set to a value of １ ／ of the interval between the protrusions 22. Moreover, the projection 22 has a substantially hemispherical projection with a diameter of 4 mm. Therefore, the presence of the protruding portion 22 on the exterior paper 20 is almost inconspicuous, and even if printing is performed on the outer surface of such an exterior paper 20 in the same manner as a normal simple container, the protruding portion 22 does not make it look unsightly. Thus, a simple container having high commercial value is provided.

Next, still another embodiment will be described with reference to FIGS. This embodiment is similar to the second embodiment.
In the embodiment of the present invention, in particular, before winding the exterior paper 20 around the outer surface of the body 10, the glue 33 is applied to the outer surface of the body 10 in a streak shape in the vertical direction as shown in FIG. ing. Alternatively, as shown in FIG. 14, the glue 33 is spirally applied in a streak shape. The exterior paper 20 is further wound on the body 10 to which the glue 33 is applied.

According to such a configuration, the exterior paper 20 is more reliably joined to the outer surface of the body 10 by the glue 33 applied in a streak shape. Moreover, since the streaked glue 33 interposed between the exterior paper 20 and the body 10 functions as a rib in a solidified state, it functions as a skeleton for the container, and gives the container high rigidity. Becomes possible. That is, a heat-resistant container that is not easily deformed is provided. In addition, since it is possible to provide rigidity by the glue 33, it is possible to reduce the thickness of the body 10 of the container or the thickness of the exterior paper 20, thereby enabling cost reduction. Become.
