Description

TECHNICAL FIELD The present invention relates to a spout of a packaging container used for filling and sealing milk, juice and the like.

2. Description of the Related Art Conventionally, in the case of pouring out the contents of a packaging container, for example, in a packaging container used for milk, juice, etc., a pouring opening is formed by cutting or pushing open the container sealing part. However, it requires scissors to form the pouring opening, requires a considerable force to push open, and is unsanitary because the pouring opening comes into contact with fingers. If a spout is provided by a hermetically sealed cap as a means, the spout body and the cap must be separately manufactured and combined, which results in a large number of manufacturing steps and cost.

Problems to be Solved by the Invention The present invention is processed so that the lid is separated from the main body and used as an opening / closing lid without opening the sealing portion to remove the contents or removing the sealing cap. By attaching the spout to the packaging container via the brim-shaped peripheral edge, the spout can be opened easily, and too much force is required when the lid is closed, causing the top lid to accidentally sink into the spout. In order to obtain a spout of a packaging container which is hygienic, easy to manufacture and has a simple operation, the lid can be closed so as not to cause the above problem.

Means for Solving Problems The present invention has the following structure of the spout for achieving the above object.

That is, according to the present invention, a linear thin groove serving as a hinge portion is provided on one side of an upper inner edge of a cylindrical base portion of a spout having a flange-shaped peripheral portion for attaching to a packaging container, and the hinge portion is provided. A thin-walled portion is formed so that it can be cut along the upper inner edge of the tubular base portion from the vicinity of both ends, and is formed on the back surface of the upper lid to a size that can be fitted into the tubular base portion through the linear thin groove and thin-walled portion. A spout that is formed by connecting an upper lid having a tubular portion that has a cylindrical thin-walled groove that serves as the hinge portion, and the upper lid is upward on the upper lid upper surface side and the tubular base portion side near the hinge portion. Locking pieces that can be locked to each other when rotated are formed respectively, and a knob piece projecting from the cylindrical base portion to the outer peripheral side is provided at the tip of the upper lid opposite to the hinge portion of the upper lid. Furthermore, the back surface of the upper lid collides with the upper edge of the cylindrical base, and the upper lid is submerged in the spout. It relates spout of the packaging container, characterized in that to prevent that.

In addition, the present invention resides in the spout of the above packaging container,
The present invention relates to a spout of a packaging container, characterized in that the above-mentioned knob is connected to an upper lid via a thin portion so as to have flexibility.

Action The spout of the present invention is used by attaching it to any packaging container.When the contents filled and sealed in the packaging container are to be dispensed, the top lid and the dispensing body can be separated by pulling the top lid upward. It is possible to form the pouring opening by breaking the thin wall portion between them and rotating the upper lid about the hinge portion.

Thus, in the spout of the present invention, when the upper lid is closed, the tubular portion provided on the back surface of the upper lid is fitted into the tubular base portion,
This prevents the back surface of the upper lid from colliding with the upper edge of the cylindrical base portion and causing the upper lid to sink into the spout.

Further, in the pouring outlet of the present invention, by interposing a linear thin groove serving as a hinge portion and providing locking pieces on the upper surface of the upper lid and a cylindrical base portion in the vicinity of the hinge portion, the pouring outlet of the present invention can be set at any desired position. Even if it is attached to the packaging container, the opening state of the spout can be maintained.

Further, in the spout of the present invention, by providing the tubular portion on the back surface of the upper lid, the upper lid can be securely fitted into the tubular base portion to close the lid.

Embodiment Next, the present invention will be described in more detail with reference to an embodiment shown in the drawings.

The drawings show an embodiment according to the present invention.
FIG. 2 is a perspective view showing the unopened state of the spout in a semi-sectional view,
FIG. 3 is a half sectional perspective view showing an opened state, and FIG. 3 is a half sectional perspective view also showing a lid closed state.

The spout 1 shown in the drawings can be integrally made of synthetic resin such as polyethylene, that is, can be made by injection molding into one piece. The upper lid 2 is continuously connected to the upper surface of a cylindrical base portion 5 having a flange-shaped peripheral edge portion 4 for attachment to The tubular base portion 5 is formed by a thin wall portion 9 formed so that the tubular portion 8 formed on the back surface of the upper lid in a size that can fit in the base portion 5 can be separated from the vicinity of both side ends of the hinge portion 7 along the upper inner edge of the tubular base portion. And the upper lid 2 and the tubular base portion 5 with the hinge portion 6 interposed therebetween, respectively, with locking pieces 10 and 11 which can be locked to each other when the upper lid 2 is rotated upward. is there.

Reference numeral 5a in the drawing denotes a temporary fixing projection of the spout to the mounting holes of the packaging container provided in the cylindrical base portion 5 of the spout main body 3, and reference numeral 8a in the drawing denotes a cylindrical portion 8 Is a protrusion that is appropriately provided on the outer wall surface of the upper lid 2, and is provided so that the tubular portion 8 of the upper lid 2 and the tubular base portion 5 of the spout main body 3 can be fitted and locked well.

Further, at the end of the upper lid opposite to the hinge portion 6, the cylindrical base portion 5
The knob piece 12 is provided so as to project further to the outer peripheral side so as to be used when opening and closing the upper lid.

With this configuration, when the upper lid is closed, as shown in FIG. 3, there is no possibility that the rear surface of the upper lid collides with the upper edge of the cylindrical base portion 5 and the upper lid 2 sinks into the spout.

The knob 12 is flexible with respect to the upper lid 2 (for example, the connecting portion between the knob 12 and the upper lid 2 is somewhat thin).
Since the knob 12 is bent and the cutting force does not reach the thin portion 9 even if a force is accidentally applied to the knob 12, the opening due to mischief or the like can be prevented.

Since the spout according to the present invention is constructed as described above, by pulling the knob piece 12 upward, the upper lid 2 is moved from the tubular base portion 5 of the spout body 3 along the thin portion 9 to the hinge portion 6. The pouring opening is formed by being cut to the vicinity and pivoting around the hinge portion 6 formed by the linear thin groove 7.

When the thin-walled portion 9 is torn, the thin-walled portion 9 and the linear thin-walled groove 7 of the hinge portion 6 are not connected to each other so that the linear thin-walled groove 7 of the hinge portion 6 is not torn. Keep it.

Further, as the upper lid 2 is rotated, a locking piece 10 provided on the upper lid 2 and a locking piece 11 provided on the tubular base portion 5 of the spout body 3 with the hinge portion 6 sandwiched therebetween are shown in FIG. To engage,
The upper lid 2 is held in an open state.

That is, by providing the locking pieces 10 and 11 as described above, the spout according to the present invention can be attached to an arbitrary packaging container, for example, without hooking the tip of the tab 12 on the container. However, the opened state can be maintained, and the contents can be poured out without anxiety.

When the upper lid 2 is pushed down when the pouring of the contents from the packaging container is completed, the tubular portion 8 provided on the back surface of the upper lid is replaced by the tubular base portion of the spout main body 3 as shown in FIG. The upper lid 2 is connected in a state in which the upper lid 2 is closed by fitting it into the interior of the upper lid 2 and fitting and locking it. Further, the tubular portion 8 provided on the back surface of the upper lid 2 has a tubular base portion 5.
This is to prevent the back surface of the upper lid 2 from colliding with the upper end edge of the cylindrical base portion 5 by being inserted into the inside of the upper lid 2 and to be immersed in the spout.

Effect of the Invention In the spout of the packaging container according to the present invention, an upper lid having a hinge portion is formed by grasping a piece of the upper lid and pulling to cut a thin portion connecting the upper lid and the spout body. So you can easily form a spout,
When opening the spout, the fingers are not in contact with the area around the spout, which is sanitary, and when closing the spout, the back surface of the upper lid collides with the upper edge of the cylindrical base,
There is no risk of the top lid immersing in the spout.

Further, when the knob is provided with flexibility, even if a force is accidentally applied to the knob, it is possible to prevent the knob from bending and applying a cutting force to the thin portion.

Furthermore, since the spout of the packaging container according to the present invention has a simple structure and can be integrally molded by plastic injection molding, it can be manufactured at low cost.
