Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a pour-out device for a paper container, and more specifically, it can be opened without peeling the seal portion of the pack when opening a paper pack such as milk. The present invention relates to a paper container pouring tool that prevents the liquid from spilling out when the pouring plug is inserted and prevents dripping during pouring.

(Prior art and its problems) As a pouring tool applied to a rectangular parallelepiped paper container filled with milk, juice, etc., one end has a pyramidal tip and the other end is sealed. A spout provided with a lid for use is known. This pour-out tool directly inserts into the paper container and takes out the contents from the pouch. However, the pour-out tool is attached to the paper container by manually pressing the paper container and inserting the pour-out tool. However, usually such a paper container
Since the content liquid is fully poured and there is almost no head space, there is a disadvantage that the content liquid is ejected when the pouring tool penetrates the paper container by the force of the hand that presses the container.

For this reason, it is known that a holder made of a resin having rigidity is attached to the upper part of the container, and the holder is gripped to attach the spout, but since the holder is easily detached from the paper container, There is a drawback that the holder goes out when pouring, and the pouring tool also goes out. Furthermore, in this type of pouring tool, the pouring stopper is inserted into the paper container by the engagement of the screw between the pouring stopper and the holder. It also has the drawback that it will come out of the paper container with the screws.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a paper container pouring tool in which a holder is engaged with a flap portion of the container so as not to be easily removed.

(Means for Solving the Problems) According to the present invention, a box-shaped holder including a top plate portion and a side surface portion for covering an upper portion of a rectangular parallelepiped paper container having an inverted triangular flap on a side surface, and the holder. It is a combination with a pouring plug that fits in a hole provided in the top plate part of the holder and has a sharp cone at the tip, and a fixing projection corresponding to the shape of the flap is provided inside the holder. Provided is a paper container pouring tool, which is provided at a position of a flap at the time of mounting, and the protrusion and the flap are locked at the time of mounting so that the holder is tightly fixed to the paper container.

(Operation) The spout of the present invention comprises a holder and a spout. The paper pack to be applied is generally of a rectangular parallelepiped type, and is formed into a rectangular parallelepiped by folding one laminated body, and therefore two triangular flaps are formed on each of the upper and lower sides. The flaps are folded down to the bottom side, but the upper two flaps 4 are folded to the side because they are cut with scissors to serve as spouts.

In the present invention, a protrusion is provided on the inside of the holder so as to engage with the flap folded on the side, so that when the paper pack is inserted into the holder, the holder is tightly fixed to the paper pack. . When opened, the inside of the container is full and the holder and the paper pack are in close contact with each other, which prevents the paper pack from being deformed even when the spout is inserted. The splash of liquid is also eliminated. Further, the holder and the paper pack are not easily detached even when pouring the liquid, which prevents dripping.

Further, since the holder is fixed to the paper container, the holder is prevented from rising when the pouring plug is inserted, and the pouring plug can be easily inserted.

(Embodiment) Referring to FIG. 1 for explaining a dispenser of the present invention, a holder 1 made of a rigid material such as plastic is sized to fit snugly on a paper pack 2, and has a top plate portion 3 and side surface portions. It is formed from four. The top plate portion 3 of the holder 1 is provided with a hole 6 for mounting the spout plug 5. The hole 6 is formed with a cylindrical portion 7 provided with a thread groove so as to be fitted with a screw provided on the pouring plug 5 described later. Further, fixing projections 9 for engaging with the flaps 8 are formed on the surfaces 4a and 4b corresponding to the flaps 8 of the paper pack 2 inside the side surface portion.

This fixing projection 9 depends on the shape of the flap 8,
Generally, since the flap has an inverted isosceles triangular shape, the fixing projection 9 is provided when the holder is completely fitted to the paper container.
Two right triangles are provided inside the holder so that the flaps are sandwiched on both sides of the inverted triangular flap. The cross section of the fixing projection 9 is tapered so as to increase toward the top plate portion.

Further, the air hole hole 10 may be formed if necessary. Furthermore, the holder side surface portion 4 preferably has a grip portion 11 having at least two side surfaces extending to the vicinity of the central portion of the paper pack so that it can be easily fixed by hand.

The pouring plug 5 fitted into the hole 6 of the holder 1 has a cylindrical upper part, and a cut is made in the paper pack 2 at the tip of the lower part so that the pouring plug 5 is sharp. A conical pyramid 12 is formed. A packing 13 is provided above the conical portion 12 and at the lower end of the cylindrical portion so that the spout 5 can be closely fitted to the paper pack 2. This can prevent liquid leakage. A screw 14 is provided on the upper cylindrical portion of the packing 13 so as to fit with the holder 1. A spout 16 having an upper lid 15 is formed at the upper end of the cylindrical portion. The top lid 15 is removable from the spout 16 and can be resealed when the contents remain. Above the threaded portion 14 of the cylindrical portion, a knob 17 for screwing the spout 5 is inserted.
Is provided.

FIG. 2 shows the holder 1 completely fitted in the paper pack 2. FIG. 3 is a cross-sectional view of a portion A which is an engaging portion between the flap portion 8 of the paper pack 2 and the fixing projection 9 in FIG. 2, and as can be seen from this cross section, the fixing projection 9 is the flap 8. Engages to support the bottom edge. This cross section shows a cross section of the flap 8 near the midpoint of an isosceles triangle of an isosceles triangle, and the fixing projection 9 is located lower than that shown in FIG. In the vicinity of the top plate portion of the paper pack 2, the fixing projection 9 is located above that shown in FIG.

As described above, since the fixing projection 9 has a tapered shape whose cross section increases toward the top plate portion, the holder 1 can be easily inserted into the paper pack 2. When the paper pack 2 is completely fitted, it cannot be removed only by pulling the holder 1. The holder 1 cannot be removed unless the side surfaces 4a and 4b of the paper pack 2 are indented to disengage the engagement between the flap 8 and the fixing projection 9.

(Effect of the Invention) The pouring tool of the present invention is provided with the fixing projection inside the holder and the flap of the paper container is engaged, so that the holder does not easily come off from the paper container and the pouring stopper is attached. It is possible to eliminate the disadvantages of the conventional pour tool, such as the floating of the holder at the time of insertion and the removal of the holder at the time of pouring the content liquid, which causes the pour tool to come out. In addition, the pouring tool of the present invention, when inserting the pouring tool into the paper container,
It is also possible to prevent the contents from popping out by pressing the hand to fix the container. Further, it can be reused after being used once, and it is economically excellent. Further, even if the contents are left, it can be sealed, which is hygienic.
