Description

[Detailed explanation of the idea] The present invention relates to a paper container with a built-in bag body.

Traditionally, paper containers with a built-in bag for storing contents such as alcoholic beverages and soybean oil have been generally rectangular cylindrical in shape, and the top surface of the container has been formed into a trapezoidal shape with a sloped portion or a mountain-like shape with a pointed tip. Paper containers were commonly used.

However, since the upper part of this container was trapezoidal or mountain-shaped, the stacking pressure strength was low and it may be impossible to stack them.
Alternatively, there is a problem that the stacked state is unstable, and the volume becomes smaller due to the sloped portion.

Therefore, it is possible to create a cubic container with a flat top, but in this case, the spout would have to be installed on the front or top plate of the container, which would cause the spout to protrude, making transportation difficult. There is a problem that the product becomes rough when packed in a box.

On the other hand, in all of the containers having the above-mentioned shapes, the spout is exposed to the outside, so that there is a hygienic problem in that drops of the contents flow down after the contents are poured out.

This invention was made to eliminate the above-mentioned drawbacks.
The purpose of the present invention is to provide a paper container with a built-in bag which has a high stacking pressure strength, is stable in a stacked state, and is hygienically suitable.

That is, the present invention provides a container with a built-in bag, which is composed of a bag that stores contents and has a spout, and a paper container body that houses the bag. A fan-shaped movable side plate that enters the container body is connected to both sides, and a locking protrusion is provided on the arcuate surface of the movable side plate, and the spout is exposed from the upper side of the container body to the front of the top plate. The gist of the present invention is to provide a paper container with a built-in bag, characterized in that a connecting plate having an opening therein is extended, a folding portion is provided on the connecting plate, and the top plate is configured to be openable and closable.

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

1 to 3 show a paper container 1 with a built-in bag, which is an embodiment of the present invention.

This paper container 1 stores contents such as alcoholic beverages and soybean oil, and is composed of a bag body 2 having a spout 16 and a paper container body 1' containing the bag body 2.

The paper container body 1' has a front plate 3, a rear plate 4, and two side plates 5, 6.
, a bottom plate 7 and a top plate 8, and has a substantially rectangular cylindrical shape, and the bag body 2 is made of two synthetic resin films, and the periphery is heat-sealed to form a bag shape.

Connected to both sides of the top plate 8 are fan-shaped movable side plates 9.1'0 that come into contact with the inner walls of the two side plates 5 and 6 of the container body 1' and enter into the container body 1'.

Also, a connecting plate 11 extends from the top of the front plate 3 to the front of the top plate 8.
The top plate 8 is connected to the upper part of the rear plate 4 so as to be openable and closable.

(FIG. 1 is a diagram showing a state in which the top plate is closed, and FIG. 2 is a diagram showing a state in which the top plate is opened.

) The connecting plate 11 is provided with one folding part 12, and an opening 15 is bored in the lower part of the folding part 12 of the connecting plate 11. The spout 16 is facing toward the outside.

Protrusions 13 are provided at a portion of both ends of the top plate 8, and the protrusions 13 function as hooks for fingers when opening and closing the top plate 8, and furthermore, when the top plate 8 is closed, ,
As shown in FIG. 4, the protrusions 13 come into contact with the upper ends of the side plates 5, 6 and are locked, so there is no risk that the top plate 8 will enter the container body 1' any further.

A locking protrusion 14 is provided at the lower part of the arcuate surface of both movable side plates 9, 10, and the locking protrusion 14 is attached to the upper end of the front plate 3 when the top plate 8 is opened, as shown in FIG. Since the top plate 8 can be fixed in an open state, there is no possibility that the top plate 8 will close during pouring of the contents.

In manufacturing the paper container 1 with a built-in bag according to the present invention, it can be manufactured by folding a developed view as shown in FIG. 3 and pasting the container at appropriate points with an adhesive or the like.

In this method, the spout 16 of the bag 2 faces the opening 15 of the connecting plate 11 of the container body 1', and the bag 2 is fixed to appropriate locations on the front plate 3 and side plates 5 with adhesive or the like.

Next, fold the front plate 3 along the bending lines 18a and 18b.
, assemble the rear plate 4, side plates 5, 6, and bottom plate 7, attach the adhesive margin 19a to the side plate 6, and attach the bottom plates 7 to each other,
Next, the bending line 18c is bent, the adhesive margin 19b is adhered to the connecting plate 11, and the cap 17 is fitted to the spout 16 to complete the finished product.

FIG. 6 shows a paper container 1 with a built-in bag which is another embodiment of the present invention.
It is shown.

In this embodiment, the connecting plate 11 has two folding parts 12.
Connecting plate 11 between two folding parts 12 and 12
An opening 15 for exposing the spout 16 is bored at the site.

FIG. 7 shows a developed view of the container 1 in this example.

Incidentally, the position of the opening 15 provided in the connecting plate 11 is not limited to the above-mentioned position, and the opening 1 is provided at the part of the connecting plate 11 located at the lower part of the lower folding part 12 of the two folding parts 12.
5 may be provided.

Further, the number of folding portions 12 provided on the connecting plate 11 may be three or more, and in this case, any position on the connecting plate 11 can be selected as the position where the opening 15 is bored.

To pour out the contents from the paper container 1 as described above, pull the top plate 8 upward while hooking your fingers on the protrusions 13 provided at both ends of the top plate 8, and move the movable side plates 9, 10. The lifting of the top plate 8 ends when the locking protrusion 14 provided at the lower part of the arcuate surface contacts and locks the upper end of the front plate 3 (FIG. 2).

In this state, the cap 17 of the spout 16 is removed, the paper container 1 is tilted, and the contents are poured out.

At this time, the movable side plates 9 and 10 connected to the top plate 8 are located approximately on the same plane as the side plates 5 and 6 of the container body 1', so that the contents are transferred to the movable side plates 9 and 10, the top plate 8, and the connected side plates. It is smoothly poured by being guided along the plate 11,
In addition, the space near the spout 16 is formed relatively narrow by the top plate 8, the connecting plate 11, and the movable side plates 9, 10, and as a result, the pressure of the contents applied to the spout 16 is reduced, causing stagnation in pouring and At times, a large amount of contents does not flow out and can be poured out stably and reliably at an appropriate flow rate.

Furthermore, since the spout 16 can be positioned at an angle to the horizontal direction, the contents can be poured out extremely easily by simply tilting the container body 1 slightly.

In addition, since the side plates 5, 6 and the movable side plates 9, 10 are not folded inward and are located substantially on the same plane, the contents remain in the folded portion inside the container during dispensing, preventing complete outflow. This will not cause any problems such as

After pouring out the contents, fit the cap 17 into the spout 16, then push down the top plate 8 with your fingers and press the protrusion 1 provided on the top plate 8.
3 comes into contact with and locks the upper ends of the side plates 5 and 6, the connecting plate 11 and the spout 16 are completely housed within the container body 1', and the upper surface of the container 1 is formed into a flat shape. Figure 1).

At this time, since the upper surface of the container 1 is flat, the stacking pressure strength of the container 1 is large, and when the containers 1 and 1 are stacked on each other, the stacked state becomes stable.

Furthermore, since the spout 16 is completely housed within the container body 1', it is not exposed to the outside, and after pouring out the contents, the spout 16 is housed within the container body 1'. This is preferable from a hygienic point of view since there is no possibility of dripping.

As explained above, the paper container with a built-in bag according to the present invention has a top plate that can be opened and closed, so when the top plate is closed, the top surface of the container becomes a flat cube, and as a result, the containers are separated from each other. The stacking pressure strength is high when stacked, and the stacked state is stable.

In addition, since the spout is housed inside the container body, the spout is not exposed to the outside, and if the top plate is closed immediately after pouring the contents, there is no risk of the contents dripping down. Hygienic and convenient.

In addition, when the top plate is closed, no slope is formed on the top surface of the container, and the volume can be reduced, and since the spout is housed inside the container body, it does not protrude outside. There is no need for extra space for the product when packing it into a box for transportation, and the product does not rust.
Can be packed tightly.

On the other hand, when the top plate is open, the contents are guided along the top plate and the connecting plate, and the pressure of the contents applied to the spout is small, so pouring may be delayed or a large amount of contents may be poured at once. There is no need to pour out the liquid, and pouring can be performed smoothly.

In addition, since the spout faces the connecting plate that has a folding part, when the top plate is opened, the spout can be positioned at an angle to the horizontal direction, allowing you to easily store the contents by simply tilting the container body slightly. Pouring things out is extremely easy.

In addition, unlike a monotonous rectangular cylindrical container, the top plate is provided so that it can be opened and closed, so it has various advantages such as a novel appearance and a great design effect.
