Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container having a three-dimensional and realistic pattern on its outer surface and a method for producing the same. Specific examples of its use include jelly and jam. In addition, it is used to express the same fruit as the fruit of the food on the outer surface of the container in a container for filling and packaging a food using a required fruit or a food having a taste of fruit.

[0002]

2. Description of the Related Art Conventionally, as a method for producing a container having a fruit pattern on its outer surface, for example, Japanese Patent Publication No. 1-54180.
The method found in the publication is known. This involves attaching a pre-printed plastic film to give a fruit-like appearance after thermoforming and a thermoformable plastic sheet, with a gradation part between which two or more colors change continuously. This is a method of forming a container by combining, drawing, and stretching the gradation part. In the container obtained by this manufacturing method, the color of the gradation portion is changed to a blurred state by stretching.

[0003]

However, in the above-mentioned conventional manufacturing method, since the plastic film is printed in two or more colors so as to have a fruit-like appearance, the fruit on the outer surface of the molded container is simply Only the color of the fruit appears to change, and the expressed fruit does not give a three-dimensional effect, and the design peculiar to the fruit is not expressed realistically. Specifically, in the case of fruits such as peach and kiwi whose surface is covered with delicate hairy skins, the colors of the skin and hairy parts of the skin are harmonized to develop color. It was extremely difficult to express this in a realistic manner.

Further, the conventional method is suitable for expressing one fruit, for example, an apple on the entire outer surface of one container, but a plurality of overlapping fruit grains such as grapes are used. When expressing, there is no stereoscopic effect or perspective produced by the fruit grains on the front side and the fruit grains on the back side, and the shadows between these fruit grains. However, the contour of each grape grain of the grape is elongated and deformed at the stretched portion of the container after molding, which is disadvantageous because it is stretched by stretching during drawing.
This is the same even if there is only one fruit to be expressed, for example, a fruit having many depressions on its surface, such as a strawberry, and having seeds therein.

The present invention solves the above problems and provides a container formed by drawing a laminated sheet, which has a realistic appearance similar to that of natural fruit and has a three-dimensional pattern. A method for manufacturing the container is provided. In the present invention, the super-realistic painting method means
A technique for creating paintings that expresses things in their natural state.

[0006]

The container of the present invention is a container formed by drawing a film laminated sheet, and a plurality of films printed with a pictorial pattern from an original image produced by a super realistic painting method It is characterized in that it is overlapped so as to be reconstructed and is attached and molded on a draw-formable sheet made of synthetic resin. Further, the manufacturing method of the present invention is a synthetic resin in which a picture pattern is printed on each of a plurality of films from an original image produced by a super-realistic painting method, and the plurality of printed films are superposed so as to reconstruct the original image. It is characterized in that it is attached to a draw-forming sheet for laminating and laminated, and the laminated sheet is drawn to form a container.

In the above-mentioned container of the present invention, an inner container in which a film on which a picture pattern is printed from an original image produced by a super-realistic painting method is laminated on a draw-forming sheet made of a synthetic resin, and a super-realistic painting method is used. A film printed with a picture pattern from the produced original image was composed of an outer container laminated on a synthetic resin drawability sheet, and the inner container was fitted into the outer container so as to cover the outer surface of the inner container. It also includes the configuration. Further, in the method of the present invention, a picture pattern is printed on one or more films from an original picture produced by a super realistic painting method, and the printed film is attached to a synthetic resin draw-formable sheet. And then stack and draw the laminated sheet to form the inner container, and print a pattern on one or more films from the original image produced by the super realistic painting method, and then print this The film is attached to a drawability sheet made of synthetic resin to be laminated, and a step of drawing the laminated sheet to form an outer container, and a step of forming the outer container in the outer container so as to cover the outer surface of the inner container. The step of inserting the inner container to form the container is included. In the manufacturing method described above, the original image of the picture pattern to be printed on a plurality of films may be reduced in advance in accordance with the stretch ratio at the time of draw forming. Alternatively, a translucent film or a drawability sheet may be superposed and attached.

[0008]

[Operation] In the container according to the present invention, the picture pattern and the discolored portion printed on the first film are expressed slightly inside the outer surface of the container, and the second film is formed on the outer surface with a slight interval. Since the picture pattern printed on the first film is expressed, the picture patterns of both films are superimposed on the outer appearance of the container, and the printed pattern of the first film has a sense of depth and a stereoscopic effect. Since these picture patterns are printed using original pictures drawn by the super realistic painting method, they have an extremely realistic and three-dimensional appearance.

Further, according to the manufacturing method, even if the picture pattern is stretched by drawing, the first film is provided with a picture pattern in which the discolored portion is arranged at an arbitrary position regardless of the drawing ratio by the drawing ratio. Since it is printed on the entire surface, it is not necessary to align the center of the container with the pattern when molding.
Since the center of the container can be set at an arbitrary position in a continuous picture pattern and draw-formed, the so-called multi-chambering that forms multiple containers simultaneously without impairing the realism of the picture pattern by draw forming Will also be possible. A picture pattern that may be deformed under the influence of stretching due to draw forming, draws a pattern in the stretched region of the first film in a dimension reduced in advance by calculating the stretch ratio by the draw ratio,
In addition, since the discolored portion and the shadow are colored and printed in conformity with this pattern, the center of the container is aligned with the center of this pattern during drawing, and by stretching, the inside of the stretched area The picture pattern is stretched by a predetermined dimension and continues in a natural state with the picture patterns of other parts, resulting in a realistic and three-dimensional appearance.

[0010]

EXAMPLE FIG. 1 shows an example of a container obtained by an example of the present production method. In this embodiment, a fruit having a pictorial pattern that does not lose its realism even when stretched by drawing is three-dimensionally expressed. In FIG. 1, a peach is used as such a fruit. This container 1 is made of a drawable sheet 2 made of a synthetic resin having thermoplasticity such as polypropylene, a first film 3 made of a transparent synthetic resin which can be thermoformed, and a transparent or translucent synthetic resin. A laminated sheet 5 is formed by the second film 4, and the laminated sheet is heated and drawn.

As shown in FIG. 2, a pattern of a peach skin is printed on the first film 3, and a delicate shape 6 of the skin is formed.
Since it does not impair realism even when stretched by drawing, it is printed on the entire surface regardless of the drawing ratio by the drawing ratio. Further, the color changing portion 7 in which a certain color continuously changes to another color is printed at an arbitrary position on the first film 3 without taking the stretching rate into consideration. The design and color are used to draw an original image by a super-realistic painting method, and the original image is printed on the first film 3 by a known method. In the second film 4,
As shown in FIG. 3, a pattern 8 of minute hairs is printed in the required color on the entire surface in the same manner as described above. The thickness of both the films 3 and 4 is about 0.02 to 2 as in the conventional case.
It may be about 0.1 mm, but preferably 0.02 to 0.
The thing of 06 mm is used.

The first film 3 is laminated on the draw-formable sheet 2 with the printing surface 3a inside, and then the second film 4 is also laminated with the printing surface 4a inside. It is laminated on the outer surface to form a laminated sheet 5 as shown in FIG. This drawability sheet 2
Is the base material layer of the container, and its thickness can be appropriately selected in consideration of the application of the container, etc., but it is possible to prevent ink cracks on the printing surface 3a of the first film 3 during drawing. In order to suppress and not affect the color of the printing surface 3a, it is desirable to color it in white.

The laminated sheet 5 is heated and drawn as in the conventional method to form the container 1. In this case, the first film 3 is printed on its entire surface with the pattern 6 of the skin whose discoloration is not impaired even when stretched by drawing and the discolored portion 7 arranged at an arbitrary position. The pattern 8 of the minute hair printed on the film 4 is extremely fine and is not affected even when stretched. Therefore, it is not necessary to align the center of the container with the pattern printed on the printed surface. It is possible to set the center of the container at an arbitrary position of 3a and perform draw forming. Therefore, the drawing work is facilitated, and by enlarging the area of the laminated sheet 5, it is possible to carry out so-called multi-chambering in which a plurality of containers are simultaneously formed.

The container 1 manufactured according to this embodiment is
As shown in FIG. 1, a fine pattern 6 of the skin printed on the first film 3 and a discolored portion 7 in which the color continuously changes in an arbitrary portion are expressed slightly inside the outer surface of the container. The entire outer surface is covered with a pattern 8 of minute hairs printed on the second film 4 with a minute interval.
For this reason, a depth feeling and a three-dimensional effect are generated in the skin part of the peach appearing in the appearance of the container, and the pattern 8 of the minute hairs is visually recognized by overlapping with the pattern 6 of the skin, and a realistic appearance similar to that of a natural peach. Is obtained.

FIG. 5 shows an example of a container obtained by another embodiment of this manufacturing method. In this embodiment, a fruit having a pictorial pattern that is likely to be deformed under the influence of drawing by drawing is expressed. In the container 1a, a group of grape berries 9 is expressed as such a fruit. .

In this embodiment, as shown in FIG.
The grape clusters 9 are printed on the first film 3.
The original image used for this printing is drawn by the above-mentioned super-realistic painting method. At this time, the design in the region (m) stretched by drawing is calculated by the drawing ratio based on the drawing ratio and is reduced by that amount in advance. It is drawn with a little size. In addition, the discolored portion 10 and the shadows 11 between the fruit grains are colored in the stretched region (m) so as to match the design. On the second film 4, small water droplets (polka dot pattern) 12 are printed at arbitrary positions, but this is another small shape that is not affected by stretching,
For example, gold powder, dew condensation, fog, or dew drops may be used.

The first film 3 and the second film 4
Is laminated on the drawability sheet 2 made of a synthetic resin having thermoplasticity to form a laminated sheet 5 as in the above example, and this is draw-formed to manufacture the container 1a. In this draw forming, the center of the container is aligned with the center of the cluster fruit grains 9 on the printing surface to perform positioning.
The design and color in the stretched region (m) are stretched to a predetermined size and continue in a natural state with the design and color of other portions, resulting in a three-dimensional and realistic appearance.

As shown in FIG. 5, the container 1a obtained by this embodiment has a pattern of clustered fruit grains 9 printed on the first film 3, a discolored portion 10 and a shadow 11 arranged on this pattern. The pattern 12 of the water drops printed on the second film 4 is three-dimensionally expressed on the inside of the outer surface of the container without being deformed unnaturally, and further on the outside thereof at a slight interval. For this reason, the cluster fruit 9 has a three-dimensional effect by the pattern itself, but the sense of depth and the three-dimensional effect are further amplified, and it is as if the grapes were washed with water and the water droplets 12 adhered to them. The appearance is excellent.

Although the container of the above-mentioned embodiment is integrally formed by drawing, the container of the present invention is a printed pattern of the first film 3 laminated on the draw-formable sheet 2 made of synthetic resin. And an outer container 1c having a printed picture pattern of the second film 4 and covering the outer surface of the inner container are separately drawn, and the inner container is fitted into the outer container. It is also possible to integrate them (see FIG. 5).

Although the laminated sheet 5 is formed in three layers in the above embodiment, the container and the manufacturing method of the present invention are not limited to this, and a semitransparent sheet with or without a pictorial pattern is used. By further laminating the third and subsequent films,
It can also be realized by forming the laminated sheet 5 in a multi-layer structure of three or more layers.
