Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a spout for a packaging container used for filling and sealing milk, juice, alcoholic beverages, 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 sealing cap must be manufactured separately and then combined, which has the drawback of increasing manufacturing time and costs.

Means for Solving the Problem The present invention allows the container to be dispensed with its contents without having to push open the seal or remove the seal cap, 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 that is hygienic, easy to manufacture, and easy to operate, and that can be easily attached to the packaging container. .

In order to achieve the above object, the present invention attaches a lid with a protruding knob to the upper surface of the cylinder and the bottom of the cylinder through a thin groove that can be separated and a thin groove that serves as a slightly thicker hinge. The peripheral wall surface of the synthetic resin pouring spout is tapered into a tapered shape, and the peripheral wall surface of the synthetic resin spout is provided with a flanged peripheral edge for joining with the peripheral edge of the opening drilled in the packaging container. It is as follows.

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 periphery of the lid is cut open by pulling the protruding knob. 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 and The burrs created on the periphery of the lid during separation prevent the lid from jumping up and opening.
The spout can be reliably closed, and since the cylindrical body is tapered, the spout can be smoothly attached to the packaging container.

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, Figures 2 and 3 are the left side view and right side view of Figure 1, respectively, and Figure 4 is a partial view of the spout connected to the Goebelt-Pseal paper container. This is a cross-sectional view.

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. The lid 2 is provided with a hook-shaped locking piece 6 on the opposite side of the thin-walled groove 4 serving as a hinge, and a locking protrusion 7 on the upper end. A protruding knob 8 is provided. In the illustrated embodiment, the cylindrical body 5 has a substantially pentagonal shape, and the thin-walled portions 3 and 4, which are connected to the lid 2, also have a pentagonal shape. When grasped and pulled, the thin wall portion 3 is torn, a lid 2 is formed with the thin wall groove 4 serving as a hinge portion 9, and the upper portion of the cylindrical portion 5 is opened. In addition, in order to prevent the lid 2 from sinking into the cylindrical part 5 when closing the lid 2, the protruding knob part 8 is
A locking protrusion 7 is configured to lock with the upper part of the cylindrical portion. Further, a plurality of temporary fixing protrusions 10 and a brim-like peripheral edge part 13 are provided at the lower part of the peripheral wall surface 11 of the cylindrical part 5, and this peripheral wall surface 11 is located at the hinge part 9 of the hinge lid 2 when viewed from the side. The height gradually increases from the side toward the spouting part at the tip, and tapers from the brim-like peripheral edge 13 toward the upper surface of the cylindrical body 5. When the spout 1 configured as described above is inserted into the perforation opening of the packaging container 12 from the inside, since the cylindrical portion 5 is tapered, the spout 1 is inserted into the perforation opening 14 of the container. can be easily inserted.
Further, the spout 1 is welded to the periphery 15 of the opening of the container after the spout 1 is temporarily fixed to the periphery 15 of the container opening by the temporary fixing protrusion 10 and the flanged periphery 13. In this way, the opening periphery 1 of the container 12
When an ultrasonic horn or a heat bonding head for welding the spout 5 and the flanged peripheral edge 13 is crimped from above the spout 1, the temporary fixing and the taper of the cylindrical portion facilitate the mutual position regulation operation.

FIG. 4 shows an embodiment in which the spout 1 is connected to a Goebelt push seal type paper container 12. In this case, the lid 2
It is preferable to provide the spout 1 at a position such that the hook-shaped locking piece 6 at the tip of the protruding knob 8 can lock onto the top seal portion 16 when opened. In this way, when dispensing the contents of the packaging container 12, the protruding knob 8 of the lid 2 is pulled, the thin groove 3 is torn off, and both ends of the thin groove 4 that become the hinge part 9 are separated. When the lid 2 is rotated about the hinge part 9 and the hook-shaped locking piece 6 is locked to the top seal part 16, a spout for the liquid content becomes tapered and opens on the top surface of the pentagonal cylindrical part 5. However, by tilting the container 12, the contents can be safely poured out. Furthermore, when dispensing is stopped, the hook-shaped locking piece 6 can be removed from the top seal part 16 and the lid 2 can be fitted into the spout of the pentagonal tubular part 5. The lid 2 is locked to the cut-out opening edge of the spout, preventing the lid 2 from falling into the inside of the container 12, and the lid 2 and the peripheral wall 11 of the pentagonal cylindrical portion are engaged with each other due to burrs generated at the cut portion. This allows the spout to be closed. The hook-shaped locking piece 6 of the protruding knob 8 may be in the form of a pull ring, and may be used without being locked to the top seal.

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,
When the lid is pushed down, the burrs around the lid engage and hold the lid in the closed position, allowing it to remain closed.The spout, which is connected to the packaging container, is made of plastic injection molding and can be easily made in one piece. Can be produced,
Moreover, when welding the brim-like peripheral edge to the opening in the container, the cylindrical part 5 is tapered, so that it is easy to insert it into the opening in the container and attach the welding head. This can be done reliably even if there is an error in the relative position.
