Description

[Detailed Description of the Invention] Technical Field This invention relates to a packaging container with a spout used for filling and sealing milk, juice, etc.

Conventionally, when dispensing 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 form a dispensing opening. Furthermore, in bag-in-box type containers for alcoholic beverages, etc., it is customary to remove the sealing cap and then cut off the sealing part to form a spout.
Therefore, in the case of Goebeltsipseal paper containers, a considerable amount of force is required to form the pouring opening.
It is unsanitary because your hands come into contact with the pouring opening.
In addition, when the spout is provided with a sealed cap, the spout main body and the cap must be manufactured separately and combined, resulting in an increase in manufacturing time and cost.

Purpose This invention enables the lid to be opened and closed by cutting off the top surface, leaving only a portion, without having to push open the seal or remove the sealing cap to pour out the contents, unlike conventional packaging containers. By attaching the spout component processed to the packaging container via the brim-shaped peripheral edge, the spout can be easily opened and the lid can be closed as necessary, making it hygienic. The present invention aims to provide a packaging container with a pouring spout that is easy to manufacture and easy to operate.

Structure In order to achieve the above object, the present invention attaches a lid provided with a protruding knob to the upper surface of the cylinder through a thin groove that can be separated and a thin groove that serves as a slightly thicker hinge part. A synthetic resin pouring spout component is attached to any packaging container, which has a flanged peripheral edge for connecting to the opening peripheral edge drilled in the packaging container on the underside of the body. When pouring, pull the protruding knob to cut open the thin edge of the lid, rotate the lid around the hinge formed by the slightly thicker groove to open the spout, and pour out the contents. When the liquid is poured out and the dispensing is stopped, the opening created by cutting the lid and the burrs created during separation on the periphery of the lid prevent the lid from jumping up and opening, and the spout can be reliably occluded.

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 plan view of the spout component 1, FIGS. 2 and 3 are the left side view and right side view of FIG. 1, respectively, and the fourth
The figure is a partial cross-sectional view of an embodiment in which the spout component is joined to a Gebelt push seal type paper container, FIG.
FIG. 6 and FIG. 7 show another embodiment.
Figures similar to Figure 3, Figures 8, 9, and 10 are perspective views showing examples in which spout constituent members are attached to various packaging containers, respectively.

The spout component 1 shown in the drawings 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 wall portion 3 that can be broken at the periphery and a hinge. It is connected to the upper surface of the cylindrical part 5 via a thin groove 4 that serves as a
The lid 2 is provided with a protruding knob 8 having a hook-shaped locking piece 6 and a locking protrusion 7 at the upper end on the opposite side of the thin groove 4 serving as the hinge. In the illustrated embodiment,
The cylindrical portion 5 is approximately pentagonal, and the thin grooves 3 and 4 that connect to the lid 2 also have a pentagonal shape.When the protruding knob 8 is grasped and pulled,
The thin groove 3 is torn to form the lid 2 with the thin groove 4 as the hinge part 9, and the upper part of the cylindrical part 5 is opened to form a tapered pouring part. In order to prevent the lid 2 from sinking into the cylindrical portion 5 when the lid 2 is closed, the locking protrusion 7 of the protruding knob portion 8 is configured to lock with the upper portion of the cylindrical portion.
Further, a plurality of temporary fixing protrusions 10 and a brim-shaped peripheral edge part 13 are provided at the lower part of the peripheral wall surface 11 of the cylindrical part 5, and the spout component 1 configured in this way
When inserted into the perforated opening of the packaging container 12 from the inside, the spout component 1 is temporarily secured to the opening periphery 14 of the container by the temporary securing protrusion 10 and the brim-shaped peripheral portion 13, so that the joining of the two is prevented. It is convenient for The container opening periphery 14 and the brim-shaped periphery 13 may be welded together by heating, ultrasonic waves, or the like.

FIG. 4 shows an embodiment in which the spout component 1 is joined to a Goebelt top seal-shaped paper container 12. In this case, when the lid 2 is opened, the hook-shaped locking piece 6 at the tip of the protruding knob 8 is attached to the top seal. It is preferable to provide the spout component 1 at a position where it can be locked to the spout 15. 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 15, a spout for the liquid content opens on the top surface of the pentagonal cylindrical part 5, and the container 12 is opened. If you tilt it, you can pour out the liquid content with confidence. When dispensing is stopped, the hook-shaped locking piece 6 can be removed from the top seal part 15 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.

Effects In the packaging container with a spout according to the present invention, the spout can be easily formed by pulling the protruding knob of the spout component and tearing the thin peripheral edge of the lid. It is hygienic because your fingers do not come into contact with the surrounding area, and when closing the spout, pressing down on the lid engages the burrs that have formed around the lid and holds the lid in the closed position, making it easier to close the spout. The state can be maintained. The spout component that is joined to the packaging container can be easily manufactured as a one-piece piece by plastic injection molding, and its brim-shaped peripheral edge can be welded to the opening drilled in the container, making it inexpensive to manufacture. is also easy.
