Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an assembling waterproof trash can, which is a disposable trash can made of a laminate of plastic film and cardboard through a release varnish.

<Prior Art> A large number of disposable and assembling trash boxes made of a single paper layer have been put into practical use.

However, when a dust containing water is put in, the material of the trash can softens and deteriorates, impairing the self-reliance, leaking water, or providing a trash can or a closing means whose top surface is always open. Even the trash cans that were present could not be kept clean when they fell.

<Problems to be Solved by the Invention> The present invention is intended to solve the above-mentioned problems, and maintains independence even when dust containing water is put in, and water leakage does not occur.
In addition, it is possible to provide a trash box which is economical and has good moldability, in which the trash thrown into the trash box does not spill outside even if it falls.

<Means for Solving the Problem> According to the present invention, a foldable paper tube made by stacking a plastic film on a cardboard, in which bent pieces having apexes eccentric to each other in the same direction are continuously provided on each side plate. Match the bottom shape to the part that is the body and will be the bottom when assembling,
A peeling varnish is applied, and at the time of assembling the cylinder, the upper surface is opened only downward by folding the bending piece inward, and the lower surface is peeled off by the peeling varnish, and the plastic film is peeled off. The above problem was solved by forming the bottom surface with only a plastic film.

<Operation> Since the present invention has the above-described structure, the vertically assembled prefabricated trash can has a tubular shape when opened, and since the release varnish is applied near the bottom, the plastic film is Peel off to form a bag-shaped bottom. Further, on the upper surface, the bent pieces are alternately folded inside and locked below the upper surface opening portion, so that they are opened only in the downward direction.

<Examples> The present invention will be described below with reference to illustrated examples.

FIG. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a plan view in which it is folded in two in the longitudinal direction and sealed by a seal portion, and FIG. 3 is a plan view of a blank sheet. Yes,
FIG. 4 is a side view showing an embodiment, and FIG. 3 is a blank sheet (A) obtained by laminating a polyethylene film (a) on a cardboard (b).

First, with the central vertical ruled line (1) as the axis, the ruled lines (2),
(3) intersects, and the bent pieces of (4), (5), (6), and (7) are connected to each other.

In addition, the seal parts (10) and (11) are provided via the ruled lines (8) and (9) that connect both ends of the ruled lines (2) and (3), and the central vertical ruled line that can be folded in two at the center ( A cut line (14) connecting the inner ends of the right-angled ruled lines (12) and (13) is provided.

The bottom line (15) (the hypotenuse in Fig. 3) consisting of two triangles with the score line (14) as the bottom and the vertex on the central vertical ruled line (1) is peeled off before laminating the plastic film on the paper. The varnish is coated.

At this time, the thick paper shall have a basis weight of 300 g / m ² ,
As the release varnish, for example, DG Hakurinis (made by Morohoshi Ink Co., Ltd.) is preferable, and the polyethylene film is preferably 50 μm.

Further, for laminating this film on a cardboard, a urethane two-liquid reaction type adhesive, for example, TX1580 (manufactured by Toyo Morton Co., Ltd.) is preferable.

With the polyethylene layer inside, cut line (14), ruled line (1
Fold it in half from 2) and (13), and seal it on both sides (10) and (11).
When each is heat-sealed, the assembly type simple trash can of the present invention, which is folded in two as shown in FIG. 2, is completed.

Open this, and insert the upper bent pieces (4), (5), (6), (7) in a staggered manner, and fold them together, and the upper bent pieces (4), (5), (6), (7)
By the repulsion of each other, the lid that is locked and opened only downward is completed.

In order to further diversify the present invention, the following things are possible.

(1). The shape of the upper and lower open portions is not limited to a quadrangle, but may be a triangle or a hexagon or an octagon by changing the shape of the bent piece.

(2). For the inner plastic film, not only the polyethylene film of the example but also a polypropylene film or a laminated film can be used depending on the application.

In addition, a deodorant and an aromatic compound kneading film can also be used.

(3). By applying offset or gravure printing to the outside in advance, it is possible to obtain a trash box with a beautiful appearance.

<Effect> (1). The open bottom surface is horizontal, so it is highly self-supporting.

(2). The inner surface is made of a plastic film, and even water containing a lot of water does not deteriorate the strength of the cylinder,
Can maintain independence.

(3). Since the upper bent pieces are folded alternately, only the lower part is opened, so even if you fall, no dust will come out.
