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 Goebert-tup seal paper container used for milk, juice, etc., the container sealing part is pushed open to open the pouring opening. However, forming the spout opening requires a considerable amount of force, 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 main body and the cap must be manufactured separately and then combined, which has the drawback of increasing manufacturing time and costs.

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. The spout is hygienic, easy to manufacture, and easy to operate, and when the lid is closed, the opening/closing lid does not fall into the inside of the spout and cease to function as a lid. It is an object of the present invention to obtain a spout that allows smooth separation when opening the spout.

Means for Solving the Problems In order to achieve the above object, the present invention provides a reinforcing piece on the tension knob provided on the top surface of the lid, so that when the tension knob is pulled to cut the lid along the thin groove, the tension This prevents the knob from being torn off from the top surface of the lid before the thin groove breaks, and prevents the tension knob from tilting and causing the stopper to not engage with the outer periphery of the spout and causing the lid to fall into the spout. The aim is to ensure that the

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 that is created on the periphery of the lid and the lid when they are separated prevents the lid from jumping up and opening, allowing the spout to be reliably closed. In addition to preventing the tension knob from being torn off from the lid when opening and closing the lid, the tension knob does not bend when opening or closing the lid, and the stopper locks on the outer periphery of the spout, preventing the lid from falling into the spout. do not have.

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, Figure 2 is a side sectional view of Figure 1, Figure 3 is a rear view of Figure 1, Figure 4 is a rear view of the reinforcing piece as part of the tension knob, Figure 5 is a perspective view when the base of the tension knob is made thinner.

The spout 1 shown in the drawing 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 groove 3 that can be broken at the periphery and a hinge part. It is connected to the upper surface of the cylindrical part 5 through a thin groove 4, and a flange-shaped peripheral part 6 for joining to a packaging container is provided at the lower edge of the cylindrical part 5. This lid 2 is provided with a tension knob 8 having a gripping protrusion 7 at the upper end on the opposite side of the thin groove 4 which serves as a hinge part, and the tension knob 8 has a tension knob 8 at its base on the lid 2 side over its entire width. Tsute reinforcing piece 10
In addition, a stopper 9 protruding outward is provided at a position slightly apart from the surface of the cylindrical portion. In the illustrated embodiment, the cylindrical portion 5 has a substantially pentagonal shape, and therefore has a thin groove 3, which is a connecting portion with the lid 2.
4 also has a pentagonal shape, and when the protrusion 7 of the tension knob 8 is grasped and pulled, the thin groove 3 is torn, and the lid 2 is formed with the thin groove 4 portion as the hinge part 12, and a cylindrical shape is formed. The upper part of the part 5 is opened to form a tapered pouring part (the thickness of the thin groove 3 is made thinner than the thickness of the thick groove which becomes the hinge part). When pulling the tension knob 8, the tensile force concentrates on the joint 16 between the tension knob 8 and the lid body 2, and the thin groove 3
The reinforcing piece 10 of the tension knob 8 prevents the joint part of the tension knob 8 from breaking before the tension knob 8 breaks, and also eliminates the deflection of the tension knob 8, so that when the lid 2 is closed, the stopper faces upward and the cylinder It locks with the upper edge of the cylindrical part without sinking into the cylindrical part.

In addition, on the lower side of the side wall surface 11 of the cylindrical part 5, a plurality of protrusions 15 for temporary fixing to the peripheral edge 14 of the spout attachment opening 13 of the packaging container and a brim-shaped peripheral edge part 6 are provided.
This side wall surface 11 is tapered toward the upper surface of the cylindrical portion 5 from the flange-shaped peripheral portion 6, so that the spout 1 can be easily attached to the opening of the packaging container.

Further, the reinforcing piece 10 at the base of the tension knob 8 may be provided as a rib-shaped reinforcing piece 10' at the center of the base of the tension knob 8, as shown in FIG. 4, without changing the effect. However, if ribs are provided on both sides of the base of the tension knob 8, dirt tends to accumulate between the rib-like reinforcing pieces. Further, as shown in FIG. 5, even when the base of the tension knob 8 is made thinner, a reinforcing piece 10'' may be provided.

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. The opening can be formed, and in this case, the reinforcing piece provided on the tension knob reinforces the root part of the tension knob to prevent the tension knob from being torn off before cutting the peripheral edge of the thin groove, and Eliminate the deflection of the tension knob,
This prevents the lid from falling into the spout without the stopper working. In addition, 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.
This spout, which can maintain a closed state and is used by joining to a packaging container, can be easily manufactured in one piece using plastic injection molding, and even if soft plastic is used, the lid will not fit inside the spout. The spout can be reliably closed without falling.
