Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a labeled container for storing foods and the like.

[0002]

2. Description of the Related Art Conventionally, as a container for storing products such as foods and beverages, as shown in FIG. 5, a body of a synthetic resin container 21 having an opening at the top is made of a heat-shrinkable film. The labeled container 20 to which the tubular label 22 was attached was used.

Such a labeled container 20 is usually a white or uncolored synthetic resin sheet formed into a predetermined container 21 shape by a forming method such as vacuum forming, and then a label of arbitrary coloring and letters or design. A cylindrical label 22 on which an indicia is printed is fitted to the body of the container, and the label 22 is heat-shrinked to be attached to the body of the container 21 in a close contact state.

[0004]

[Problems to be Solved by the Invention] However, the label
When the label 22 is heat-shrinked, the label 22 is not always uniformly heat-shrinked, so that some distortion or waviness may occur. Usually, the color of the outer surface of the container 21 is the color of the resin sheet, that is, the color of the resin itself such as white or transparent color, and is often different from the coloring of the print given to the label 22,
If the top edge 22a of label 22 is colored, label
Can be clearly seen due to the difference between the color of 22 and the color of the container 21 surface,
As a result, there has been a problem that the distortion or the like of the label 22 is conspicuous at the edge portion 22a.

In order to solve such a problem, it is conceivable to form the surface of the container with a colored resin without attaching a label and print it directly to give a display or the like. Usually, the colored resin is not colored. Since it is more expensive than a resin, in order to manufacture a colored container at low cost, the container is molded from a laminated sheet in which a colored layer made of a colored resin is laminated on the outer surface side of an uncolored resin.

However, when such a laminated sheet is formed into a shape of a container by a known forming method such as vacuum forming, the laminated sheet of the portion corresponding to the body of the container is stretched largely as compared with the upper portion and the lower portion. As a result, the color of the colored layer in that portion becomes lighter, which causes a problem in that the appearance is not preferable.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a labeled container which has a good appearance and can be manufactured economically.

[0008]

The present invention has been made to solve the above problems, and a feature of the labeled container is that the container 1 having a colored surface is used.
In the labeled container on which the label 2 is attached, the end of the label 2 is colored in substantially the same color as the surface of the container 1.

A feature of the method for producing a labeled container is that a laminated sheet 9 having a colored layer 6 laminated on one surface side is molded into a container 1 with the colored layer 6 on the outer surface,
On the outer surface of 1, a label 2 having a printed part 3 whose end is colored in substantially the same color as the colored layer 6 is attached so that the colored end is continuous with the surface of the container 2 and is visible from the outer surface. Especially.

(Operation) That is, as described above, since the label 2 whose end portion is colored in substantially the same color as the surface of the container 1 is attached to the container 1 whose surface is colored in an arbitrary color,
The boundary line between 2 and the surface of container 1 is not clearly conspicuous,
Therefore, the outer appearance of the container 1 is not impaired by the boundary line between the label 2 and the container, and the label 2 and the container 1 can have a sense of unity.

Further, when the container 1 is formed by molding the laminated sheet 8 in which the colored layer 6 is laminated on the outer surface side, the amount of expensive colored resin used can be minimized and easily. It is possible to mold a container 1 with a colored surface, and even if color irregularity occurs in the container 1 during molding, the label 2 gives a sense of unity on the body of the container 1 where the color is the thinnest and color irregularity is likely to occur. The external appearance is not impaired due to color unevenness that occurs when it is mounted and mounted.

Further, when the label 2 is composed of the heat-shrinkable film 9 attached to the container 2 by heat shrinkage, the boundary line between the label 2 and the container 1 is not clear, so that the label 2 does not shrink when heat shrinks. Even if distortion occurs due to the heat-shrinkable film 9 shrinking uniformly, it does not stand out.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 shown in FIGS. 1 and 2 denotes a container made of synthetic resin, and a cylindrical label 2 is attached to the body of the container 1 to form a labeled container 10.

As shown in FIGS. 1 and 2A, the container 1 comprises a laminated sheet 8 comprising a colored layer 6 located on the outer surface side and a white resin layer 7 laminated on the inner surface side of the colored layer. It is formed into a predetermined shape having an opening at the top by a known forming method such as vacuum forming.

The laminated sheet 8 has a thickness of 0.2 to, for example.
It is preferable that the thickness of the colored layer 6 is about 2 mm and the total thickness of the colored layer 6 is 5 to 50% or less, particularly 10 to 30%.

As the white resin layer, in addition to high-impact polystyrene, general-purpose polystyrene, polypropylene, polyethylene, polyester, etc. may be used as a single layer or a laminated layer. A gas barrier layer such as a coalesced layer may be provided.

Further, when each layer is formed by laminating materials which are difficult to adhere to each other, an adhesive resin layer or the like may be provided between the layers as necessary.

Further, the colored layer 4 is preferably colored by mixing a coloring pigment or the like with a resin of the same or similar type as the white resin layer 7 because the adhesion between resin layers and the moldability are good.

The laminated sheet 8 is, for example, a high-impact polystyrene white resin layer 7 having a thickness of about 0.8 mm, and a high-impact polystyrene colored with a thickness of about 0.2 mm. A laminated sheet having a two-layer structure in which the layer 6 is laminated by coextrusion can be used.

Further, as another example of the laminated sheet 8,
A four-layer structure in which a colored layer 6 of colored high-impact polystyrene is laminated on the outer surface side of a resin layer having a white appearance, for example, a three-layer structure having a polyethylene layer having excellent moisture resistance between high-impact polystyrene, 4-layer structure in which a colored layer 6 made of colored polypropylene is laminated on a white or natural color resin layer having a 3-layer structure in which a gas barrier layer of an ethylene vinyl alcohol copolymer is provided between polypropylene, and a resin made of vinyl chloride The one having a two-layer structure in which colored vinyl chloride is laminated on the outer surface side of the layer can be appropriately selected according to the purpose of use.

The label 2 is made of transparent polyvinyl chloride,
It is formed of a heat-shrinkable film 9 which is made of a synthetic resin such as polyester, polypropylene, polystyrene or the like and is heat-shrinkable in the circumferential direction of the container 1.

On the inner surface side of the heat-shrinkable film 9, a printing portion 3 as shown in FIG. 2B is formed, and the printing portion 3 is a display printing on which an arbitrary character or design is applied. Department
3a, a colored portion 4 provided on the upper end side of the label 2 and colored by printing in the same color as the colored layer 6 of the container, and a white printing layer provided on the entire inner surface with white ink
3b. It is preferable for the appearance of the label 2 that the colored portion 4 is provided so as to be viewed from the outside as a part of the design of the display printing portion 3a.

A transparent portion 5 having no printing is formed on the upper edge 2a of the label 2, and the colored layer 6 on the surface of the container 1 can be seen through the transparent portion 5. The transparent portion 5 may be semi-transparent enough to allow the color of the colored layer 6 to be transparent, or may be thinly transparently colored so as not to affect the color of the colored layer 6, and the point is that the colored layer 6 is transparent. .

The label 2 is attached to the body of the container 1 in a close contact state by heat contraction so that the upper edge 2a is located above the body of the container 1, and the lower end 2b of the label 2 is attached to the body. As shown in FIG. 1, it is bent toward the bottom by heat contraction.

Next, the case of forming such a labeled container will be described. First, as shown in FIGS. 3A and 3B, the laminated sheet 8 having the colored layer 6 on one surface side of the white resin layer 7. Is softened by heating, placed in a mold so that the colored layer 6 is in contact with the mold, and the container 1 having an opening at the top is molded by vacuum molding.

On the other hand, on the back side of the heat-shrinkable film sheet which is formed so as to be heat-shrinkable in the uniaxial direction, a printing section 3 provided with a display printing section 3a for arbitrary characters and designs is gravure-printed or letterpress-printed. The heat-shrinkable film sheet is formed by a known printing method such as printing so that the transparent portion 5 is slightly left in the vicinity of the upper edge 2a when the heat-shrinkable film sheet is formed on the cylindrical label 2. At this time, a colored portion 4 that is colored substantially the same as the colored layer 6 of the container 1 is provided at the end of the printed portion 3 as a part of the design of the display printed portion 3a. Further, on the innermost surface side of the printing unit 3, a white printing layer 3b having a white ink applied to the entire surface is formed.

Next, the heat-shrinkable film sheet is cut into a predetermined size and formed into a tubular shape having a diameter such that it can be fitted into the body of the container 1 to form the label 2. .
At this time, the heat-shrinkable film sheet is formed into a tubular shape so that the circumferential direction is heat-shrinked.

Next, as shown in FIG. 3C, the cylindrical label 2 is fitted into the body of the molded container 1,
Further, the label 2 is heat-shrinked and brought into close contact with the body of the container 1 to form a labeled container 10 as shown in FIG.

Labeled container formed in this way
As shown in FIG. 2 (a), 10 indicates that the color of the colored layer 6 of the container 1 is visually observed from the outer side through the transparent portion 5 located at the upper edge 2a, and the outer surface of the container 1 is continuous with the color. Since the colored portion 4 of the label 2 having the same color as that is visually recognized as a part of the design of the printing portion 3, the boundary between the container 1 and the upper end portion of the label 2 cannot be clearly discriminated, and the label 2 and the container 1 have a sense of unity. Occurs and the appearance is finished well.

Further, even when the label 2 does not shrink uniformly at the time of heat shrinkage and some distortion occurs, the color of the colored portion 4 and the colored layer 6 of the container 1 are the same, and the boundary between the two. Since it does not appear clearly, the distortion is not noticeable.

Although the colored portion 4 is provided only on the upper end side of the label in the above embodiment, the lower end 2b of the label is also located on the body of the container 1 from the outside as shown in FIG. 4, for example. In case of the label 2 where the lower end 2b of the label 2 can be seen,
It is preferable to form the colored layer 4 also on the label lower end portion 2b side.

Further, in the above embodiment, the container 1 is
Although it was formed from the laminated sheet 8 having the colored layer 6, formation from such a laminated sheet 8 is not a condition,
For example, the container may be formed from a single-layer sheet made of a colored resin, or the container surface may be colored and coated after molding. Further, the container is not limited to the container 1 formed by the synthetic resin sheet, and may be, for example, a container formed by injection molding a colored resin.

However, when the container 1 is formed from the laminated sheet 8 as in the above-described embodiment, the amount of the colored resin used is smaller than that in the case where the entire container 1 is formed of the colored resin, so that the cost is reduced. Since the container can be manufactured and the colored layer can be formed simultaneously with molding, the colored container can be easily formed.

Further, in the above-mentioned embodiment, the transparent portion 5 is provided on the upper edge 2a of the label 2, but it is not a condition to provide such a transparent portion 5, and the edge of the label 2 is colored. The part 4 may be formed.

In the above embodiment, the body of the container 1 has a substantially cylindrical shape, but the shape of the container is not limited to this. For example, the side surface may have corners. It may be a rectangular container. In the case of such a rectangular container, when a heat-shrinkable label is attached, since it has a corner, distortion is likely to occur, and therefore, there is a drawback that the corrugation at the upper end of the label becomes conspicuous. According to this, such a problem can be solved particularly effectively.

Further, although the label 2 is formed by using the transparent heat-shrinkable film 9 in the above-mentioned embodiment, the present invention is not limited to the transparent film. However, in the case of an opaque film such as white, it is necessary to form the printed portion 3 on the outer surface side of the film and the colored portion 4 up to the edge portion. Further, the label 2 can be subjected to a surface treatment or the like so that the gloss and color tone of the label surface can be matched with the surface of the container 1. In this case, a continuous sense of unity is generated between the label 2 and the container 1, The boundary of the container 1 can be made inconspicuous and the appearance can be improved.

Although the label 2 made of the heat-shrinkable film 9 is used in the above-mentioned embodiment, the label 2 is not limited to the label made of such a heat-shrinkable film, and may be made of a stretch film. Or a label attached to the container 1 via a heat-sensitive or pressure-sensitive adhesive layer on a base material made of a non-heat-shrinkable film, paper, synthetic paper, or the like. In short, the shape of the label does not matter as long as the end portion which is continuous with the surface of the container 1 and is viewed from the outside is colored in substantially the same color as the container surface.

[0039]

As described above, according to the present invention, the coloring portion provided on the label allows the outer surface of the container to be colored and the label to be visually observed continuously to obscure the boundary between the label and the container. It is possible to economically and easily provide a package with a label, which has a sense of unity and is attached to a container and has a good appearance.
