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 disadvantage 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 furthermore, when the lid is closed, the lid does not fall into the spout and cease to function as a lid. An object of the present invention is to obtain a spout for a packaging container as described above.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a lid equipped with a tension knob in a cylindrical shape through a separable thin-walled groove and a slightly thicker thin-walled groove serving as a hinge. In a synthetic resin pouring spout which is provided with a flange-shaped peripheral edge for joining with the periphery of an opening formed in a packaging container on the top surface of the lid and on the lower side of the cylindrical shape, a flange-shaped locking part is provided on the top surface of the lid. is provided, and its lower part is formed into a thick part shaped to fit into the inner wall of the spout, so that when the lid is closed, the lid fits inside the spout,
The flange-like locking portion locks onto the outer periphery of the spout so that the spout can be reliably closed without the lid falling into the spout.

Function The pouring spout of the present invention is used by being attached to any packaging container, and when pouring out the contents filled and sealed inside the packaging container, the back surface of the top wall can be separated by pulling the tension knob. The lid is formed by tearing off the thin peripheral edge of the lid, and by rotating the lid around the hinge formed by the slightly thicker thin groove, the spout is opened and the content is poured out. When the discontinuation is stopped, the opening created by cutting the lid, the burrs created during the separation and the thick part fitting part will prevent the lid from jumping up and opening, and the spout will be closed. This is to ensure that the spout can be closed securely, and to prevent the lid from falling into the inside of the spout.

Example The present invention will be explained below with reference to 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 view of Figure 1,
Fig. 3 is a cross-sectional view of the spout welded to the container, Fig. 4 is a perspective view showing the spout in an open state;
FIG. 5 is a perspective view showing the lid in a closed state.

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. Thin wall groove 4
It is connected to the upper surface of the cylindrical part 5 via
A flange-shaped peripheral edge part 6 is provided at the lower edge of the cylindrical part 5 for joining to a packaging container. This lid 2 has a flange-like locking part 7 on its outer edge and a thin groove 4 that becomes a hinge part.
A tension knob 9 having a hook-shaped locking piece 8 at its upper end is provided on the opposite side. To explain the structure in more detail, the lid 2 is formed on the upper wall surface 10 of the cylindrical part 5 in a shape that fits into the spout inner hole from the thin groove 4 toward the tension knob 9, and It consists of a thick part 11 that gradually becomes thicker toward the knob side, and a flange-like locking part 7 provided on the upper edge of the thick part 11. 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.
The shape of 4 is also pentagonal, and when the tension knob 9 is grasped and pulled, the thin groove 3 is torn, the lid 2 with the thin groove 4 as the hinge part 12 is formed, and the upper part of the cylindrical part 5 is opened. (The thickness of the thin groove 3 is made thinner than the thickness of the thick groove that will become the hinge portion.) In order to prevent the lid 2 from sinking into the cylindrical portion 5 when the lid 2 is closed, the flange-like locking portion 7 is configured to lock with the upper portion of the cylindrical body.

Furthermore, a plurality of temporary fixing protrusions 17 and a brim-shaped peripheral edge 6 are provided at the lower part of the peripheral wall surface 13 of the cylindrical part 5 to the peripheral edge 16 of the spout attachment opening 15 of the packaging container 14. The wall surface 13 is tapered toward the upper surface of the cylindrical portion 5 from the flange-like peripheral portion 6, so that the spout 1 can be easily attached to the attachment opening 15 of the packaging container.

FIG. 3 shows an embodiment in which the spout 1 is joined to a Goebelt push seal paper container 14, in which case the lid 2
It is preferable to provide the spout 1 at a position such that the hook-shaped locking piece 8 at the tip of the tension knob 9 can lock onto the top seal portion 18 when opened. In this way, when dispensing the contents of the packaging container 14, as shown in FIG. After cutting off both ends of the lid 2, the lid 2 is rotated around the hinge part 12, as shown by the imaginary line in FIG.
By locking the hook-shaped locking piece 6 to the top seal portion 18, the liquid content can be safely poured out. When dispensing is stopped, the hook-shaped locking piece 8 is removed from the top seal part 18 and the lid 2 is fitted into the opening of the pentagonal cylindrical part 5, as shown in FIG. The brim-like locking edge 7 locks on the cut-out opening edge of the spout to prevent the lid 2 from falling inside the container 14, and also prevents the burr generated at the cut portion from fitting into the rim of the cylindrical body. The lid 2 and the inner wall of the peripheral wall 13 of the pentagonal cylindrical portion are brought into engagement with each other by the thick wall portion 11 formed in the shape of , and the spout can be closed. Note that the thick portion 11 may be formed in a hollow shape.

Effects of the invention The spout of the packaging container according to the present invention can be easily formed by pulling the protruding knob of the spout and cutting the thin peripheral edge of the lid.
At that time, it is hygienic because your fingers do not touch the area around the spout, and when closing the spout,
If you press down on the lid, the burrs and thick part 1 on the periphery of the lid will be removed.
1 engages with the inner edge of the cylindrical portion 5 to hold the lid in the closed position, the closed state can be maintained, and the spout connected to the packaging container can be easily manufactured in one piece by plastic injection molding. Even if a soft plastic material is used, the lid body is provided with a brim-like locking part, so the lid will not fall into the spout, and the thick part 11 will prevent the lid body 2 from being distorted. The spout can be reliably closed without any leakage.
