Description

[Detailed description of the invention] Industrial application field This invention is a spout of a packaging container used for filling and sealing milk, juice, etc. This relates to the spout.

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 disadvantage of increasing manufacturing time and costs.

Problems to be Solved by the Invention The present invention can be opened and closed by cutting the separation band without having to push open the seal to pour out the contents or remove the sealing cap, unlike conventional packaging containers. By attaching the spout processed to form a lid to the packaging container via the brim-shaped peripheral edge, the spout can be easily opened, and the lid can be closed if necessary, improving hygiene. The purpose of the present invention is to provide a spout for a packaging container that is easy to manufacture and easy to operate.

Means for Solving the Problems In order to achieve the above object, the present invention has a cylindrical part with a flange-like peripheral part at the lower part for joining to a packaging container, and a part of the upper end of the cylindrical part has a hinge part. In a spout provided with a lid, a fitting wall portion that can be fitted to the inner wall of the cylindrical portion is provided on the periphery of the lid excluding the hinge portion, and a fitting wall portion that can be fitted to the inner wall of the cylindrical portion is provided, and between the lower end of the fitting wall and the upper end of the cylindrical portion. are joined by a separation band having a pair of tension pieces protruding from the center and separable thin parts on both edges, and the separation band is separated by pulling the tension pieces of the separation band, and the lid body is removed. The lid is configured to open and close from the cylindrical part other than the hinge part, and the fitting wall part is fitted and locked to the inner wall of the cylindrical part to close the lid after the opening is used. It is something.

Function The spout of the present invention is used by attaching the brim-shaped peripheral part of the spout to any packaging container.When pouring out the liquid that has been filled and sealed inside the packaging container, pull the tension piece. The spout is opened by separating the separation band from the spout along the thin-walled part and rotating the lid body around the hinge formed by the slightly thicker thin-walled groove provided at the connecting part with the cylindrical part. When the liquid is poured out and the dispensing is stopped, the lid is pressed to fit the fitting wall into the inner wall of the cylindrical part and close the spout.

Example The present invention will be explained according to embodiments shown in the drawings.

The drawings show an embodiment according to the present invention.
2 is a sectional view taken along line A-A in FIG. 1, and FIG. 3 is a sectional view showing the spout in a closed state.

The spout 1 shown in the drawings can be made integrally, ie, in one piece, by injection molding from a synthetic resin such as polyethylene, and in this embodiment, the spout has a substantially triangular shape. The substantially triangular cylindrical part 2 has a flange-like peripheral part 3 connected to its lower part,
A lid body 4 is connected to one side of the upper end (triangular base portion), and a hinge portion 5 formed as a thin wall portion is provided at a slight distance from the bottom of the lid body 4. Hinge portion 5 near the bottom of the triangular lid 4
A fitting wall part 6 is provided inwardly enough to form a flange part 7 along the lid body 4 from the top toward the top. This fitting wall part 6 is fitted into the inner wall of the cylindrical part 2, and gradually becomes wider from the mounting end of the hinge part, and is widest at the apex of the triangle, and has a surface that is provided with a plurality of protruding fitting protrusions.

The lower edge of the fitting wall portion 6 is connected to the separation band 1 via the thin wall portion 9.
Similarly, the other edge of the separation band 10 is connected to the cylindrical portion 2 via the thin wall portion 9. Note that tension pieces 11 and 12 are provided facing each other at the triangular apex position of spout 1, which is the center of separation band 10, and when tension pieces 11 and 12 are pulled left and right in the direction of the arrows, they are cut. The separation band 10 is cut out from the center between the fitting wall part 6 and the cylindrical part 2 in a double-sided pattern.

As shown in the figure, the triangular cylindrical part 2 is configured to be highest at its apex, and a projection 13 for temporary fixing is provided on the lower side of the outer periphery for joining the spout to the periphery of the packaging container mounting opening. .

When pouring out the liquid filled in the packaging container, pull the tension pieces 11 and 12 in the direction of the arrow, and insert the separation band 10 along the thin wall part 9 into the fitting wall part 6.
is separated from the cylindrical part 2, leaving the hinge part 5 and opening the spout. Next, the lid body 4 is rotated about the hinge portion 5 by the protruding knob 14 provided on the lid, the opening is widened, and the contents are poured out. After pouring, the fitting wall portion 6 is press-fitted into the cylindrical portion 2 and closed. At this time, the protrusion 8 on the circumferential surface of the fitting wall portion 6 makes the fitting state tight and prevents the lid from opening accidentally due to rebound.

Further, the flange of the opening/closing lid body 4 engages on the cylindrical portion 2, prevents the lid from falling further, and protects the spout when the lid is closed. The protruding knob 14 on the top surface of the lid becomes an operating knob for opening and closing the lid after opening.

In this embodiment, the spout has a substantially triangular shape, but the shape can be changed as appropriate.

Effects of the invention The pouring spout of the packaging container according to the invention can be easily manufactured in one piece by plastic injection manufacturing, and its operation is done by pulling the separation band and tearing the thin periphery of the connecting part. The spout can be easily formed, and it is hygienic because your hands and fingers do not come into contact with the spout. Also, when closing the spout, the fitting wall part must be pressed into the cylindrical part. Just by fitting it, it becomes completely closed, and since there is an overlapping part between the fitting wall part and the cylindrical part, there is no fatigue even after repeated opening and closing operations, and reliable closing is possible, making it suitable for long-term use. I can withstand it too.
