Abstract

PURPOSE:To provide a pouring outlet for carton which is simple to open and capable of resealing. CONSTITUTION:A body 2 with a carton mounting flange 21 on an outer periphery of a cylindrical part 22 and a cap 3 having inside a side wall 32 an inner cylindrical part 33 which slides rotatingly between a lower position and an upper position within the cylindrical part 22 are combined with each other. If the cap 3 is rotated to break off a connection web 32 from a guarantee strip 38, an unsealing can be achieved. If the cap 3 is further rotated so that the inner cylindrical part 33 rises up, a pouring hole 39 can appear. After content liquid is poured out, if the cap 3 is rotated in a direction to lower down the inner cylindrical part 33, the cylindrical part 33 can be pushed into the cylindrical part 22 and sealed again.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carton spout used by being attached to a carton for filling and sealing a liquid such as a beverage.

[0002]

2. Description of the Related Art Heretofore, as this type of spout, there has been known one in which a sealing member having a thin portion is provided inside a spout main body and a pull ring is provided on the sealing member (for example, the actual opening). 53-63331).

[0003]

The above-mentioned conventional spout has the advantage that the pull ring can be opened by pulling the pull ring and the cap can be closed once the content liquid is spouted. The opening operation is troublesome because it is opened after removing it.Moreover, the pull ring is inside the spout body and its diameter is small, so it is difficult to open with fingers, so the opening operation is not easy. Have

The present invention has been made in view of the above problems, and an object thereof is to provide a carton spout which is easy and easy to open and can be resealed. To do.

[0005]

In order to achieve the above object, a pouring spout for a carton according to the present invention comprises a main body having a flange on the outer periphery of a cylindrical portion for attaching to a hole provided in the carton, and A cap having an inner tubular portion inside the side wall that rotates and slides between a lower position and an upper position in the tubular portion, and a plurality of rupturable connecting webs are formed on the lower end peripheral edge of the side wall of the cap. A ring-shaped guarantee strip is connected to the inner cylinder part of the cap by engaging with a ridge that is provided around the upper part of the flange of the main body with the inner cylinder part in the lower position. It is characterized in that a pouring hole, which is exposed from the tubular portion of the main body when the inner tubular portion is raised to the upper position, is formed on the side surface of the portion.

[0006]

The above-mentioned carton spout of the present invention is used by attaching it to any liquid carton. When pouring out the content liquid filled and sealed in the carton, the cap is turned to break the connecting web. By opening, and further rotating the cap to raise the inner cylinder portion from the lower position to the upper position, so that the inner cylinder portion is pulled out from the cylindrical portion of the main body and the pouring hole is exposed. . Further, when the pouring is completed, the cap is rotated to lower the inner tubular portion from the upper position to the lower position so that the inner tubular portion is pushed into the tubular portion of the main body.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the spout according to the present invention attached to a carton, and FIG. 2 is a half sectional view showing the spout in an unopened state.

As shown in these figures, the spout 1 is formed by combining two members, a main body 2 and a cap 3 which are produced by injection molding a synthetic resin such as polyethylene.

Of these, the main body 2 is provided with a flange 21 for attaching to a hole provided in the carton C in a substantially middle stage on the outer periphery of the tubular portion 22, and a protrusion 23 is provided on an upper portion of the attaching flange 21. It has a circular structure. Further, an oblique groove 24 is formed on the inner surface of the tubular portion 22.

On the other hand, the cap 3 has a side wall 32 facing downwardly around the top surface 31, and an inner cylinder portion 33 extending downward from the back side of the top surface 31 inside the side wall 32. The outer diameter of 33 is set so as to slide tightly in the tubular portion 22 of the main body 2.
On the outer surface of the inner tubular portion 33, there are provided slanting protrusions 34 that fit into the grooves 24 on the inner surface of the tubular portion 22 of the main body 2. It is adapted to rotate and slide between a lower position and an upper position regulated by the projections 35 and 36. An annular guarantee strip 38 is connected to the lower edge of the side wall 32 via a plurality of rupturable connecting webs 37. The guarantee strip 38 is provided around the upper portion of the flange 21 of the main body 2. It is in a state of being locked to the strip 23. Further, a pouring hole 39 is provided near the upper side surface of the inner tubular portion 33, and this hole 39 is provided in the inner tubular portion 3.
It is provided at a location where it is exposed from the cylindrical portion 22 of the main body 2 when the 3 is raised to the upper position.

In order to integrate the main body 2 and the cap 3 as shown in FIG. 2, the projection 34 is fitted in the groove 24 so that the inner cylinder of the cap 3 is inserted into the cylindrical portion 22 of the main body 2. Part 33
The two are combined by pushing while rotating, and then the portion of the guarantee strip 38 is shrunk by heat to be locked to the ridge 23 of the main body 2. The means for giving the cap 3 the pilfer proof function in this way is known. Then, the spout 1 in the integrated state is attached to the spout attachment hole of the carton C for use.

When the content liquid is poured out from the carton C, the side wall 32 of the cap 3 is gripped and rotated, and the connection web 37 is pulled and broken by this operation to open the cap. That is, when the cap 3 is rotated, the protrusion 34 of the inner cylindrical portion 33 causes the groove 24 of the cylindrical portion 22 of the main body 2 to move.
Although the cap 3 tries to move up along the line, since the guarantee strip 38 is locked to the ridge 23, a tensile force that breaks the connection web 37 acts. Then, the cap 3 is rotated as it is, and the inner cylindrical portion 33 is rotated.
Is raised to the upper position, the inner tubular portion 33 is pulled out from the tubular portion 22 of the main body 2 to expose the pouring hole 39, as shown in FIGS. 3 and 4.

When the spout 1 is attached to the roof part of the Gobel top type carton C as in this embodiment, the groove 24 of the tubular portion 22 of the main body 2 is formed in order to easily pour out the content liquid. Inner tube portion 33 of the cap 3
By appropriately setting the relationship of the protrusions 34 of the inner cylindrical portion 3
It is preferable that the pouring hole 39 is exposed at the upper position of the No. 3 in a state of facing downward.

After the content liquid is poured out, the cap 3 is rotated to rotate and slide the inner cylindrical portion 33 in the cylindrical portion 22 of the main body 2 to lower it from the upper position to the lower position. It is pushed into the portion 22. When the inner tube portion 33 of the cap 3 is housed in this manner, the inner tube portion 3 of the cap 3 is stored.
Since there is no gap between the cylindrical portion 3 of the main body 2 and the cylindrical portion 22 of the main body 2, the liquid content will not be spilled even if the liquid is tilted or tilted.

[0016]

As described above, the carton pouring spout of the present invention can be opened by breaking the connecting web by turning the cap, and then pouring by turning the cap as it is to raise the inner cylinder part. Since the hole for use can be exposed, the opening operation is simple and easy.In addition, when pouring is completed, the cap is turned to lower the inner tubular part, and it is pushed into the tubular part of the main body to seal it. Because it is possible, it can be easily resealed.
