Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ribbed in-mold label container which is easy to hold by hand when contents such as boiling water are put therein and has an aesthetic appearance.

[0002]

2. Description of the Related Art Conventionally, various types of plastic containers which are easy to hold by hand when high-temperature contents are put therein have been used. For example, a double container in which an inner container and an outer container are fitted and a gap is provided as a heat insulating layer between the inner container and the outer container, a container in which a material having heat insulation is wound around the outer periphery of the container, Further, there is a container in which a fine rib-shaped protrusion is provided on the outer periphery of the container. With regard to imparting aesthetics such as a pattern to the outside of the container, in a double container or a container in which a heat insulating member is wound, a pattern or the like is printed on the outer member. In a container provided with rib-like projections, a method of forming a container and then directly performing dry offset printing or the like on a portion other than the rib-like projections of the container or attaching a printed label has been used.

[0003]

However, a conventional double container in which an inner container and an outer container are fitted together and a gap is provided between the inner container and the outer container as a heat insulating layer, the outer periphery of the container is insulated. In the case of a container wrapped with a conductive material,
The pattern is provided on the outside by printing directly on the outer periphery of the container or by winding a printed material having heat insulating properties, but there is a problem that the processing cost increases. Also, in the case of a container in which fine vertical rib projections are provided on the outer periphery of the container main body, there is a method of direct printing, but it is necessary to perform plastic surface treatment, it is necessary to avoid the rib-shaped projections, The printing method is also limited to dry offset or silk screen printing, and there is a problem that it is difficult to print on a tone pattern. Furthermore, the method of directly applying a label has a problem that a processing step for applying the label is required, and since the end face of the label is exposed, the label is easily peeled off, which is not preferable in appearance.

Accordingly, the present invention has been made to solve the above-mentioned problems, and is easy to hold by hand even when hot contents such as boiling water are put in. In addition, a pattern or a character is provided on the outside to provide aesthetics. It is an object of the present invention to provide a ribbed in-mold label container in which a label and a container main body are integrally formed.

Further, in the container body in which the rib-shaped protrusions are formed in the vertical direction over the entire periphery of the upper part of the outer periphery of the side surface, a step is formed at a position of a lower end line where the rib-shaped protrusions are formed, The label is integrated with the side surface below the step. Furthermore, the label is integrated with the bottom surface of the container body.

The method for producing a ribbed in-mold label container according to the present invention comprises the steps of: placing a label in a mold, injecting a thermoplastic resin, and integrally molding the label and the container. The method of manufacturing, wherein a thermoplastic resin is injected from one side to a label arranged in a mold, and a rib-like projection penetrating a part of the label and projecting to the other side of the label is formed on a side surface of the container. The label is formed on the outer periphery, and the label is integrated with the side surface. Further, a thermoplastic resin is injected from one side to a label disposed in a mold, and a rib-like projection which is one side of the label and protrudes to the outer periphery of a side surface of the container is formed, and the label is formed by the above-mentioned method. It is characterized in that it is integrated with the side surface and the outer surface of the rib-shaped projection.

According to the present invention, by having a rib-shaped projection provided on the side surface of a plastic cup-shaped container, even when hot contents such as boiling water are put, it is easy to hold by hand. Further, by integrating a label provided with a pattern, a character, and the like and the container body by in-mold molding, an in-mold label container with a rib having high aesthetic appearance can be obtained.

In addition, a label provided with a pattern, a character, or the like can be applied to a portion of the side surface of the container body between the rib-shaped protrusions or a portion including the outside of the rib-shaped protrusions.
