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 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. To obtain a spout for a packaging container which is hygienic, easy to manufacture, and simple to operate, and which allows reliable separation with a small force when opening the lid.

Means for Solving the Problems In order to achieve the above object, the present invention makes the base of the tension knob provided on the top surface of the lid thin, concentrates the tension at the base, and when opening the lid, the thin wall groove The structure is such that it is easy to break.

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 burrs created on the periphery of the lid and the lid prevent the lid from jumping up and opening, allowing the spout to be reliably closed. In this case, the tensile force is concentrated at the narrow neck at the base, and the thin groove can be easily broken.

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. 1, and FIG. 3 is a front view.

The spout 1 shown in the drawing can be made integrally from a synthetic resin such as polyethylene, that is, by one-piece injection molding, and the lid 2 on the top surface has a thin groove 3 that can be broken at the periphery and a hinge part. The cylindrical portion 5 is connected to the upper surface of the cylindrical portion 5 through a thin groove 4, and a flange-like peripheral portion 6 for joining to a packaging container is provided at the lower edge of the cylindrical portion 5. This lid 2 has a gripping protrusion 7 at the upper end on the opposite side of the thin groove 4 which becomes the hinge part, and a stopper 9 protruding outward at a position slightly away from the surface of the cylindrical part, and its base part is made thin. A tension knob 8 with a narrow neck 10 is provided. 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 tensile force is concentrated on the thin neck portion 10 at the base, and the thin groove 3 near the joint 16 of the narrow neck portion 10 with the lid breaks first, and then the thin groove 3
is torn to form the lid 2 with the thin groove 4 as a hinge part, and the upper part of the cylindrical part 5 is opened to form a tapered part. Furthermore, when the lid 2 is closed, the stopper 9 engages with the upper edge of the cylindrical portion to prevent it from sinking into the cylindrical portion.

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 in this case, the tensile force of the tension knob is concentrated on the narrow neck at the base, and even if pulled with a small force, the thin groove can be easily broken and the spout can be opened. 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 the spout opening can remain closed. This spout used in the spout can be easily manufactured in one piece by plastic injection molding, and even if soft plastic is used, the stopper engages with the periphery of the cylindrical part, so the lid does not fit inside the spout. The spout can be reliably closed without falling.
