DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper container filled with a detergent. Here, the term “paper container packing” is a concept in which contents are packed in a paper container as in the case of canning and bottling.

[0002]

2. Description of the Related Art Conventionally, a paper container packed with a detergent has been formed by bending a paperboard, but in recent years, the paper container body has been formed by vacuum forming or pressure forming of synthetic resin. Or a part that is to be a lid and a part that is to be a container main body are integrally formed, and a part close to the top plate surface is formed.
A paper-made sheet or the like having a band-shaped cutout provided on the side surface and having an attachment plate in contact with the inner surface of the top plate surface over the band-shaped cutout is provided on the inner wall surface at the position of the cutout.

[0003]

In a conventional container packed with a detergent formed by bending a paperboard, a lid piece extended from the container body side is folded and inserted into the container body side and welded. Therefore, in use, the cover piece is peeled off from the welded part and opened, a perforated hole provided on the side wall of the container body is opened, or a spout provided on the side wall is projected. The detergent was leaking. In recent years, such paper container packing has been used less frequently with the passage of time, and instead of this, a container body and a lid body have been used separately. Is made of paper, and the lid is made of synthetic resin.In the disposal of used empty containers, if incinerated, the synthetic resin lid emits high heat, which may damage the incinerator, It is not environmentally preferable because it generates toxic gas. Also, in the case of a strip-shaped cutout, if the strip-shaped cutout is cut out and the upper part is made into a lid, both the lid and the container body are made of paper, so it can be used for incineration after use. Even if there is no hindrance, the lid that became the opening and closing lid does not necessarily have sufficient contact with the attachment plate, and after opening, moisture enters from this part,
If knocked down, the detergent may leak.

[0004] The present invention has been made in view of the above-mentioned points, and an object thereof is to simplify the production of paper containers and to reduce the cost, and even if the cover is opened, In addition, the content of the detergent is guaranteed, and the disposal of the used container is facilitated.

[0005]

In order to achieve the above object, according to the present invention, a container body and a lid of a paper container are separated from each other, and an inner member is provided between the container body and the lid. The problem is solved by interposing a sealing material.

That is, according to the present invention, a detergent is charged into a paper container main body, and an inner seal material having a release layer in the center is adhered to the inner surface of the paper container main body with the paperboard inside. The paper cover is covered with the paper cover body, and the paper cover is attached to the paper container body via an inner seal material by applying a high frequency from above the outer surface of the paper cover. A hinge protruding piece is extended from the side wall of the crown of the body, and is attached to the outer wall of the paper container body.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. The paper container (A) of the detergent of the present invention comprises a container body (a), a lid (b), and an inner seal material (c), and contains a detergent (d) inside. The paper container includes a container body (a) and a lid (b) formed of paperboard, and these are formed by folding and bonding a paperboard. The container body (a) is formed by folding and bonding a blank plate obtained by punching a paperboard, and the upper rim (1) has a rim (2) folded inward.

The cover (b) is formed by folding and bonding a blank plate (3) punched out of a paperboard as shown in FIG.
In this drawing, the dotted line (4) is inside, and the dashed line (5)
Is a fold line that folds outward. One of the fold edges (6) has a U-shaped cut line (7) reaching the inner fold line (4).
There is a portion (8) surrounded by a circle, which is a portion serving as a protruding hinge piece as shown in FIGS. This hinge piece (8) is coated with an adhesive (9) applied to the inner surface thereof.
The lid (b) is attached to the outer wall (10) of the container body (a), and the hinge piece (8) is attached to the container body (a).
It can be opened and closed freely from the folded line (4).

An inner sealing material (c) is adhered to the inner surface of the lid (b). Inner seal material (c)
Is a laminate of paperboard (a) + polyethylene (b) / release layer (wax) (c) / aluminum (d) + polyethylene film (e) + hot melt agent (f) as shown in cross section in FIG. Made of aluminum (d)
Is 30 μm, and the hot melt agent (he) is 300 g / m ² . This inner seal material (c) is made of paperboard (a)
It is adhered to the inner surface of the lid (b) with the side facing inside. The lid body (b) having the inner seal material (c) adhered to the inner surface in this manner covers the container body (a) after the detergent (d) is charged into the container body (a), and is covered with the lid body. The hinge piece (8) of (b) is adhered to the outer wall (10) of the container body (a) with an adhesive (9), and a high frequency is applied from above and outside along the periphery of the lid (b). As for the inner seal material (c) in the lid (b), the aluminum (d) layer is heated by high frequency, the polyethylene film (e) and the hot melt agent (f) are melted, and the upper part of the container body (a) is melted. It is welded to the opening edge (1). Thereby, the paper container (A) containing the detergent (d) is completed as a product.

In order to use the paper container (A) of detergent, the boundary between the container body (a) and the lid (b) on the side opposite to the hinge piece (8) of the lid (b) is used. When the lid (b) is pulled up toward the hinge piece (8) by peeling off the sealing piece adhered to the container, the lid (b) welded to the container body (a) becomes an inner seal. The material (c) is peeled off from the intermediate wax release layer (c), and the lid (b) is exposed to the hinge piece (8). Since the aluminum (d) and the polyethylene film (e) layers are welded to the container body (a) side, the detergent (d) as the contents is still in close contact. This prevents moisture absorption and illegal use of the contents. In order to take out the detergent (d), the sealing material composed of the layer of aluminum (d) and the polyethylene film (e) is peeled off from the upper rim (1) of the container body (a) and taken out with a spoon or the like. . After taking out, when the lid (b) is returned to its original position, the lid (b) presses the sealing material peeled off from the upper rim (1), so that the detergent (d) flows out of course.
It can also prevent it from getting wet.

[0011]

According to the present invention, a detergent container is formed separately from a container body and a lid using paperboard, the detergent is charged into the container body, and a release layer is formed at the center of the container body. The inner seal material is covered with a lid adhered to the inner surface, and this is attached to the container body by high frequency, making the production relatively simple and the cost low.
Moreover, since the cover is welded via the inner seal material, the cover can be easily separated from the release layer when the cover is opened, and the separated inner seal material remains on the container body side. It is possible to prevent moisture absorption of the detergent by maintaining the hermeticity, and it is possible to guarantee the content of the detergent. In addition, because the whole is made of paper,
In the used disposal, it can be easily crushed, and even when incinerated, the incinerator is hardly damaged and the environment due to the combustion gas is hardly damaged.
