Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a plastic steion tag type easy open spigot attached to a top plate of a plastic container used as a beverage container or a composite container mainly composed of paper.
[0002]
[Prior art]
Conventionally, an easy-open lid that can be opened without the help of a can opener or the like has been widely used for the top plate of a beverage container that is a metal container. In recent years, since the tabs separated from the container are scattered and dangerous, a steion tag type easy open lid that does not separate the tag from the container even when the can is opened is generally used. Further, this metal steion tag type easy open lid is also used for a plastic container or a composite container mainly made of paper.
[0003]
[Problems to be solved by the invention]
However, from the viewpoint of promoting recycling of containers and packaging in recent years, in order to facilitate the separate collection of used containers, plastic stays instead of metal attached to the top plate of a composite container mainly composed of plastic containers or paper are used. The development of an on-tag type easy open plug has been strongly demanded.
[0004]
The present invention responds to the above-mentioned strong development demand, and provides a plastic steion tag type easy open plug that is attached to the top plate of a composite container mainly composed of a plastic container or paper.

[Action]
The container top plate (20) shown in FIG. 1 (b), FIG. 2 (a), FIG. 3 (a) or FIG. 4 (a) to which the plastic steion tag type easy open mouth plug (10) of the present invention is attached. ), When the pressing tag (120) is pushed into the container with the thumb while raising the end of the opening jar (130) of the plug with the nail of the index finger, FIG. 1 (c), FIG. 2 (b), FIG. As shown in FIG. 4B or FIG. 4B, the pressing tag and the base plate (110) are bent at the half-cut line (112), and a plurality of acute angle protrusions (121, 121) provided on the outer periphery of the pressing tag. , 121) comes into contact with the sealing film (200) arranged below, and the sealing film is broken to open the container. At the same time, the unsealing folds in a triangular shape along the half-cut line (131), and the end of the unsealing ledge moves in the direction of the plug. When the pressing tag is pushed into the container at a substantially right angle with respect to the container top plate, the end of the unsealing trough falls into the inner side surface of the stopper of the holding projection (113) of the plate-like portion of the base plate (110). The pressing tag is held in the container at a substantially right angle with respect to the container top plate.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 (a) and 1 (b), the plastic steion tag type easy open mouth plug (10) of the present invention has a seal body disposed on the bottom surface of the mouth plug body (100) and the mouth plug. And a stop film (200). The plug body is made by injection molding using a thermoplastic resin such as polyethylene or polypropylene, and the sealing film is usually a laminated film, such as an aluminum foil, a metal vapor deposited film, a gas barrier resin film, etc. A resin layer thermally bonded to the cap body or the container top plate is formed on both sides of the barrier layer.
[0010]
As shown in FIGS. 1 (a) and 1 (b), the structure of the spigot body (100) includes a base plate (110) composed of an annular portion and a plate-like portion having a holding projection (113) on the upper surface. The base plate of the pedestal plate is connected to the end in the center direction of the plug (10) via a straight half-cut line (112), and usually has a plurality of triangular pyramids on the outer periphery. A pressing tag (120) having an acute protrusion (121) and inserted into the opening (111) of the annular portion of the pedestal plate, and a column (122) on the upper surface of the edge of the pressing tag in the center direction. The bottom half is connected to the holding projection of the plate-like portion of the pedestal plate, and the straight half-cut line (131) that extends from both sides to between the holding projection and the column. And an unsealing trough (130) for forming The half-cut lines (112 and 131) are formed by providing a V-shaped cut from above, and the pressing tag is usually formed with a concave upper surface so that it can be easily pressed with the thumb. The shape of the holding projection provided on the upper surface of the plate-like portion of the base plate is adapted to the shape of the end portion in the outer side direction of the mouthpiece of the opening lid.
[0011]
Then, a sealing film is arranged on the bottom surface of the cap body, and the steion tag type easy open plug of the present invention is attached to the cap mounting hole of a container top plate such as a composite container mainly made of a plastic can or paper. For example, as shown in FIG. 1 (b), the sealing film (200) is adhered to the lower surface of the container top plate (20) using heat fusion or an adhesive, as shown in FIG. After sealing the plug attachment hole, the peripheral part of the base plate (110) of the plug main body (100) is heat-sealed to the upper surface of the container top plate by an ultrasonic sealing method or the like. It is attached to the cap attachment hole of the top plate.
[0012]
Alternatively, a sealing film is loaded in advance into the injection mold of the plug body, and the plug body is molded with a thermoplastic resin, and at the same time, the sealing film is heat-sealed to the bottom surface of the plug body and is integrally molded. The soy tag type easy open mouth plug of the present invention is produced by a so-called insert injection molding method, and the mouth plug (10) is placed on the upper surface of the container top (20) as shown in FIG. The lower surface of the sealing film (200) is heat-sealed by an ultrasonic sealing method or the like, and attached to the stopper mounting hole of the container top plate.
[0013]
Alternatively, an insert injection molding method is used to produce the steion tag type easy open plug of the present invention having a sticking portion with the container top plate on the peripheral edge of the upper surface of the base plate of the plug body, and this plug (10) As shown in FIG. 3 (a), heat is applied to the lower surface of the container top (20) by applying an ultrasonic seal method or the like to the peripheral portion of the upper surface of the base plate (110) of the plug body (100). It is fused and attached to the cap attachment hole of the container top plate.
[0014]
Furthermore, the steion tag type easy open mouth plug of the present invention in which the sealing film is heat-sealed on the inner side of the sticking portion with the container top plate at the lower peripheral edge of the base plate of the mouth plug body by the insert injection molding method As shown in FIG. 4 (a), the base plate (110) of the plug body (100) is formed on the upper surface of the container top (20) by an ultrasonic sealing method or the like. The attachment part of the lower surface peripheral part of this is heat-sealed, and it attaches to the stopper attachment hole of a container top plate.
[0015]
【The invention's effect】
The container of the present invention with a plastic steion tag type easy open spigot attached to the top plate is raised with the thumb while raising the end of the spout opening of the spout with the index finger nail when the contents are poured out. By simply pushing the pressing tag into the container, the container can be opened and no other tools are required to open it. Moreover, the pressing tag is fixedly held in the container and is not separated from the container.
[0016]
In addition, since the spigot of the present invention is made of plastic, it is easy to separate and collect at the time of disposal of the used container.
