Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a paper container with a spout.

(Prior art) Conventionally, the spout of a rectangular cylindrical paper container was attached to the roof-shaped slope at the top of the Goebel type container.
Such containers are inconvenient to store, the spout protrudes from the slope, making them easy to damage, and since the spout is directly exposed to the outside, they tend to become unclean due to dust, etc., and are difficult to transport. It has the disadvantage of being unstable in accumulation.

(Purpose of the invention) The present invention is designed to prevent the spouts of paper containers with spouts as described above from being damaged during stacking and transportation, to protect them and facilitate the collection and transportation work, and to prevent the spouts from being damaged during stacking and transportation. The purpose is to keep it clean.

(Problems to be Solved by the Invention) In order to achieve the above-mentioned purpose, the present invention provides a paper container with a spout on an inclined surface by creating a horizontal surface above the spout to facilitate storage and transportation. Also, the spout can be protected.

(Means for Solving the Problems) In order to solve the above problems, the present invention improves the upper seal part of a rectangular cylindrical paper container that has a spout on the slope for liquid, etc. The gist is that in the upper seal part of a rectangular cylindrical paper container, an inclined plate 6 is formed on the upper part of the front plate 2 with horizontal ruled lines 8 so that its upper edge coincides with the upper edge of the container. , an inclined ruled line 1 extending from both sides of the horizontal ruled line 8 located at the lower end of the inclined plate 6 to the both side plates 1 and 3 and the folding flap 14 located on the top thereof.
3 and 15, the upper part of the inclined plate 6 is pushed inward to form a slope on the upper part of the front plate 2,
The eaves plate 4a provided on the horizontal ruled line 11 located at the upper edge of the back plate 4 is folded in the folding flap 14 on the upper part of each side plate 1, 3 and then bent horizontally to form an eave shape over the spout. All of the folded portions are heated and pressurized and sealed together.

(Function) Since the present invention has the above-mentioned configuration, the eave plate provided through the upper edge ruled line of the back plate forms a horizontal eave above the spout on the slope plate and projects forward.
The spout is now protected and, moreover, stackable.

(Embodiment) The present invention has a rectangular inclined plate having a spout as shown in Fig. 1, which is placed on the upper part of the front plate through a ruled line, and above the spout, a horizontal eave is installed from the upper edge of the back plate through the ruled line. It is folded and fixed. The structure of this paper container with a spout will be explained below with reference to the developed view of FIG. 2 (however, the spout is not shown).

1 and 3 are side plates, 2 is a front plate,
4 is a back plate, and 5 is a glue piece to be attached to the back side of the side plate 1.

A rectangular inclined plate 6 is provided on the upper part of the front plate 2 so that its upper edge coincides with the upper edge of the container. The horizontal ruled line located at the upper edge of this rectangular inclined plate 6 is designated as 7, and the horizontal ruled line located at the lower edge is designated as 8.

A folding part 9 is placed on the horizontal ruled line 7.
form. The horizontal ruled line 10 on the upper edge of the side panels 1 and 3 has a length of approximately 2/3 of the width of each side panel,
It is provided horizontally from the boundary line with the back plate 4 toward the front plate. This horizontal ruled line 10 is extended onto the back plate 4 to form a horizontal ruled line 11, and an eaves plate 4a is provided above through this horizontal ruled line 11.

From both ends of the horizontal ruled line 8 of the inclined plate 6 on the upper part of the front plate 2 to the tip 12 of the horizontal ruled line 10 of the side plates 1 and 3
An inclined ruled line 13 passing through is provided. This inclined ruled line 13
is further extended as an inclined ruled line 15 to the tip of the folding flap 14 on the side plate, and the tip is designated as 16. This tip 16 is connected to the tip 17 (on the back plate side) of the horizontal ruled line 10 on the side plate with an inclined ruled line 18, and also from this tip 16 to the end 19 of the horizontal ruled line 7 on the inclined plate 6 is connected with an inclined ruled line 20. .

From one end 12 of the horizontal ruled line 10 of the side plate to the inclined plate 6
Connect the ends 19 of the horizontal ruled lines 7 with the inclined ruled lines 21,
This is further extended to the leading edge of the folded portion 9 on the upper edge of the inclined plate 6 to form an inclined ruled line 22. Approximately in the center of the inclined surface 6 is a spouting hole 2 to which a spout B is attached.
3 is provided.

To assemble the paper container main body A with a spout formed in this way, first attach the glue strip 5 to the back surface of the back plate 4, and the upper opening will have an external shape as shown in FIG. . Next, push the inclined plate 6 inward as shown in FIG.
Fold horizontally forward through horizontal ruled lines 11.

In this state, the folded portions of the upper opening are all heated and pressurized and heat-sealed together to form a strong eaves horizontally as shown in FIG. Also the fifth
As shown in FIG. 9, the folded portion 9 may be left unfolded into a flat plate shape without being folded in along the inclined ruled lines 22.

The spout B can be installed while the container body A is a blank sheet, but it is generally installed from the inside of the container as shown in Figure 3, or from the outside after sealing as shown in Figure 5 A and B. It is true.

(Effects) Since the present invention has the above-mentioned configuration, the flaps on each side panel are stacked on top of each other on the inclined panel at the top of the front panel to form a horizontally stacked eave, which is sealed by heating and pressing. Therefore, since the eaves have sufficient strength and form a horizontal surface, it is possible to stack many containers upward, making it convenient for collection and transportation.The spout is sufficiently protected by the eaves, and is not directly contaminated by dust. It can be said that this is a significantly effective improvement over this type of paper container that has a spout on the slope.
