Description

[Detailed description of the invention] The present invention relates to an insertion discharge frame for paper containers, etc., and is a hollow, push-in type with opening through holes at the upper and lower ends, which is conventionally used in rectangular paper containers for drinking water, etc. A dispensing frame has been known, but this dispensing frame penetrates the sloped wall of a rectangular paper container and only supports the stopper with the broken part of the sloped wall, but the dispensing frame wobbles, When used repeatedly, the contents tend to leak or come out through the broken parts.

The present invention has been developed to eliminate the drawbacks in view of the above points.
As shown in the figure, the present invention has a discharge plug main body 1 in which the back fin at the upper end of a rectangular paper container having a roof-shaped upper part has a clip structure that makes it easy to grasp, and the sloped wall of the roof-shaped upper part can be easily inserted.
This is a plug-in discharge plug made of synthetic resin, metal, etc. and a cap 2.

When molded from synthetic resin, the discharge plug body 1 can be made of a hard material such as acrylonitrile-styrene copolymer (AS resin), and the cap 2 can be made of high-pressure polyethylene or the like.

To explain in more detail, it is an inverted U-shaped clip that holds the dorsal fin-like top part 4 of a rectangular paper container having a roof-shaped upper part 3 from above, and the length that becomes the leg part of this inverted U-shaped clip is A long cylindrical body 5 and a short cylindrical body 6 having different heights are formed with a distance approximately equal to the thickness of the dorsal fin-like top portion 4 of the container, with a bridge portion 7 interposed therebetween.

The tops of the long cylinder 5 and the short cylinder 6 are opened with discharge ports 8, 8' through which the contents are poured out.
A spout cylinder 9, 9' is formed in the lower part of the spout cylindrical body 9, 9' which is hollow and communicates with the spout and is exposed to the outside from the sloped wall of the container when the stopper is inserted into the container.

The cross-sectional shape of the pouring cylinders 9, 9' is approximately square in this embodiment, but the cross-sectional shape of the pouring cylinders 9, 9' is not limited to a circle or an ellipse in the present invention. The inner walls facing each other are provided with sawtooth-like protrusions 10° and 10' that are shaped to engage with the insertable dorsal fin-like top portion 4.

Also, below the pouring cylinders 9, 9', there are connected liquid circulation cylinders 11, 11' which are embedded in the container when the stopper is inserted. 11' is also a hollow body through which the contents flow through the spout cylinders 9, 9'.

Here, the outer peripheral shape of the liquid flow cylinder 11, 11' is a slanted circular shape that improves the degree of adhesion to the wall when the stopper is inserted and the slope wall is broken. ', and the liquid flow cylinders 11, 11' and the pouring cylinders 9, 9
A stepped portion 12.12' is provided in the continuous portion with '.

This stepped portion 12.12' serves to prevent the contents from leaking around the hole made in the sloped wall when the stopper of the present invention is inserted.

Next, a content suction portion 13.13' projects from the lower end of the liquid flow cylinder 11.11' made of a cylindrical wall.

This content suction part 13.13' is connected to the liquid flow cylinder 11.11.
A plate-shaped lattice part 14.14' that is divided into several parts (three in this embodiment) from the lower end of ' extends downward toward the center and gathers at the center position, and the gathering part is sharp. The tip has a piercing cutting edge 15.15', and this lattice part 14.1
4', the long cylindrical body part 5 is longer than the short cylindrical body 6, and the gaps between the lattice parts 14 and 14' serve as intake ports 16 and 16' for the contents.

In the drawings, reference numeral 2 denotes a cap, which is rotatably attached via a protrusion 17 provided on the discharge plug main body 1.

Next, as a method of using the present invention, as shown in FIG. 3, the tip 15 of the long cylinder body 5 is used to pierce the adjacent part of the dorsal fin-like top part 4 of the roof-shaped upper part 3 of the paper container. to drill a small hole,
Furthermore, a small hole is bored in a portion adjacent to the dorsal fin-like top portion 4 of the other roof-shaped upper portion 3 using the piercing cutting edge 15 of the long cylinder 5.

Insert the long cylindrical body 5 and the short cylindrical body 6 into the two small holes drilled here so as to straddle the dorsal fin-like apex 4 until the dorsal fin-like apex 4 hits the bridge part 7. Discharge becomes possible as shown in Figure 2.

It should be noted that the insertion operation will be easier if the position of the small hole to be drilled on the sloped wall of the container is marked in advance by printing or the like.

The present invention has the above-mentioned configuration, and it is possible to dispense by simply inserting the plug-in discharge stopper, without having to perform the complicated operation of breaking the dorsal fin-like top of the paper container to open it, as in the past. Also, due to the hardness of the material of the paper container or the slanted walls, if you try to insert both cylinders at the same time by straddling the dorsal fin-like top, the piercing blade tip will escape and you will not be able to insert it. If a small hole is made in advance in the slope wall using the piercing edge of a long cylinder, the discharge plug can be easily inserted.

Furthermore, since the liquid flow cylinder embedded in the container has a circular outer circumferential shape, it has good adhesion to the broken wall, and the outer shape of the liquid flow cylinder and the pouring cylinder are different, making it difficult to connect to the connected part. Since the step is provided, this step covers the hole drilled in the slope wall, so the plug-in type discharge plug has excellent sealing performance.
