Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a spout of a packaging container used for filling and sealing milk, juice, etc.

BACKGROUND ART Conventionally, when pouring out the contents of a packaging container, for example, in the case of a Goebelt-tup seal paper container used for milk, juice, etc., the container sealing part is pushed open to open the pouring opening. However, it requires a considerable amount of force to form the spout opening, which is unhygienic as hands and fingers come into contact with the spout opening, and the spout is provided with a sealed cap as a means of forming the opening. In this case, the spout body and the cap must be manufactured separately and combined, which has the disadvantage of increasing manufacturing time and costs.
Further, it was not easy to impart virgin proof.

Problems to be Solved by the Invention This invention eliminates the need to push open the seal or remove the sealing cap to pour out the contents, unlike conventional packaging containers. By attaching the spout, which has been cut off to form an opening/closing lid, to the packaging container via the flanged peripheral edge, the spout can be easily opened, and the lid can be closed if necessary. It is a spout that is hygienic, easy to manufacture, and easy to operate, and when the lid is closed, there will be no situation where the opening/closing lid falls into the inside of the spout and ceases to function as a lid. In addition, this prevents the container from being delivered to consumers in a condition where the cut-off point on the top of the pouring spout opens due to some external force while being transported or displayed at the store, and the value of the container as a sealed packaging container is lost. The present invention aims to provide a spout for a packaging container that is also virgin proof.

Means for Solving the Problems In order to achieve the above object, the present invention provides a stopper that also serves as virgin proof on the tension knob provided on the top surface of the lid, and the stopper is installed before the lid is separated along the thin groove. configured such that a strip-shaped thin piece continuous between the tip and the side wall surface is cut, or
By attaching a similar thin strip from the gripping protrusion of the tension knob, you can not only confirm whether the lid has already been opened, but also allow the stopper to lock onto the outer periphery of the spout and close the lid. The purpose is to make it possible to reliably close the spout without falling into the spout.

Function The pouring spout of the present invention is used by attaching it to any packaging container, and when pouring out the contents filled and sealed inside the packaging container, the thin peripheral edge of the lid is broken by pulling the tension knob. Then, by rotating the lid around the hinge formed by a slightly thicker thin groove, the spout is opened and the contents are poured out. When dispensing is stopped, the opening created by cutting the lid open is opened. The burr created on the periphery of the lid and the lid prevents the lid from jumping up and opening, allowing the spout to be reliably closed.Furthermore, the stopper prevents the lid from opening. Not only will it not fall into the outlet, but it will also be possible to confirm whether the lid has already been opened by checking whether the continuous thin piece is cut.

Embodiments Hereinafter, the present invention will be explained according to embodiments shown in the drawings.

The drawings show an embodiment according to the present invention.
The figure is a perspective view of the spout, FIG. 2 is a side sectional view of FIG. FIG. 5 is a diagram similar to FIGS. 1 and 2 showing another embodiment.

The spout 1 shown in FIGS. 1 to 3 can be integrally made of synthetic resin such as polyethylene, that is, by injection molding into one piece, and the lid 2 on the top surface has a thin wall that can be broken at the periphery. It is connected to the upper surface of the cylindrical part 5 via the groove 3 and a thin groove 4 which serves as a hinge part, and a flange-shaped peripheral part 6 for joining to a packaging container is provided on the lower edge of the cylindrical part 5. . This lid 2
is provided with a tension knob 8 having a gripping protrusion 7 at its upper end on the opposite side of the thin groove 4 serving as the hinge part, and a stopper 9 projecting outward from this tension knob 8 is attached to a cylindrical part. The stopper 9 is provided at a position slightly apart from the surface, and a thin strip connecting piece 10 is connected to the side wall surface 11 of the cylindrical portion 5 from the tip of the stopper 9. In the illustrated embodiment, the cylindrical portion 5 has a substantially pentagonal shape, and therefore the thin grooves 3 and 4 that connect to the lid 2 also have a pentagonal shape. When the protrusion 7 is grasped and pulled, the thin strip 10 is cut before the thin groove 3 is torn.
The lid 2 is formed with the thin groove 4 serving as the hinge part 12, and the upper part of the cylindrical part 5 is opened (the thickness of the thin groove 3 is thinner than the thickness of the thick groove serving as the hinge part). ).

Therefore, the stopper 9 provided on the tension knob 8
Since a strip-shaped thin connecting piece 10 is provided between the tip and the side wall surface 11 to connect the two, it is not only possible to easily check whether the spout 1 has not been opened yet, but also to ensure that the stopper 9 does not close to the lid. The lid 2 is engaged with the upper edge of the cylindrical part 5 to prevent it from sinking into the cylindrical part 5 when the lid 2 is closed.

In addition, in the spout 1 shown in FIGS. 4 and 5, the strip-shaped thin connecting piece 10' that connects the tension knob 8 and the side wall surface 11 does not come from the stopper 9, but from the gripping protrusion 7 and the side wall surface 11. The spout is different from the spout shown in FIGS. 1 to 3 in that it is provided between the spouts, but the other configurations are the same, so a description thereof will be omitted.

In addition, on the lower side of the side wall surface 11 of the cylindrical part 5, there are provided a plurality of temporary fixing protrusions 15 and a brim-like peripheral part 6 to the peripheral part 14 of the spout attachment opening 13 of the packaging container. The wall surface 11 is closer to the cylindrical portion 5 than the brim-shaped peripheral portion 6
It has a tapered shape towards the top surface,
The spout 1 can be easily attached to the opening of the packaging container.

Effects of the invention The pouring spout of the packaging container according to the present invention can easily form a lid and pour at the same time by pulling the tension knob of the pouring spout and cutting the thin periphery that will become the lid at the same time as cutting the strip-like thin connecting piece. An opening can be formed, and at that time, depending on whether or not the strip-shaped thin connecting piece provided between the tip of the stopper provided on the tension knob and the side wall of the cylindrical part of the spout opening is cut or disconnected, the spout opening can be formed. It is easy to visually check whether the lid has already been opened, and the stopper prevents the lid from falling into the spout. In addition, since the lid is held in the closed position by the engagement of the burrs generated on the periphery of the thin groove by cutting the thin groove, the lid can remain closed and can be joined to the packaging container. The spout can be easily manufactured in one piece using plastic injection molding, and even if soft plastic is used, the lid will not fall into the spout.
The spout can be reliably closed.
