Description

[Detailed description of the invention] (Industrial application field) The present invention relates to containers used for transporting tobacco.

(Prior art) For example, fresh tobacco leaves or tobacco that has been reconstituted after aging (reconstituted tobacco)
Certain containers, such as barrels and cartons, are used to transport the (instituted tobacco) from the country of origin to the country where the final product is manufactured.

Traditionally, fresh tobacco leaves are heated and made pliable by steam, and in this state about 1000 leaves are deposited in columns.
cm of leaves are compressed by a compressor to about 70 cm and placed in a cardboard carton box. When compressing,
A metal sleeve or corset is inserted into an empty carton box. When the compressor head returns to the top of its stroke, the sleeve is removed and the M
(flap) is closed and a string etc. is hung. The cigarettes may then be disinfected with a gaseous disinfectant.

(Problems to be Solved by the Invention) The cigarettes in this carton box require packaging treatment such as external taping. The reason for this is that tobacco plants tend to germinate before they are cooled down. This packaging process is time consuming and adds additional cost to the cost of the cartons. Carton boxes are fragile due to their wooden nature, and the contents can shrink when handled with a forklift, especially in humid conditions, or when stacked. , more easily broken. Therefore, these cartons can only be used for one-time transportation.

British patent specification GB-A-946466 discloses that a plywood (pallet) is integrally assembled, and the front, side, rear, and top walls and slide clasp 1 fastener (
sliding clasp fastener: hereinafter referred to as a sliding clasp fastener. ) is disclosed having a bottom wall connected by. This is not suitable for solving the above problems. This is because there is no explanation of how the lid of the container is made. It's also because walls obviously don't have ventilation.

The present invention has been made in view of the above points, and an object of the present invention is to provide a container suitable for transporting tobacco leaves.

Means for Solving the Problems According to the present invention, the bottom, top, rear, front and side walls of a rectangular shape are made of woven fabric in order to accommodate compressed tobacco in one wheel size chunks. A container may be provided which is made of a flexible sheet of unspecified shape and whose top wall is connected along at least three edges to the top of the adjacent wall by sliding fasteners.

(Operation) A container constructed as described above can be filled by means of a hydraulic compressor in substantially conventional manner. When the compressor head is removed, it quickly closes the top wall, which forms the hinged lid of the container, and is secured by a sliding fastener, before the tobacco expands upwards past the top edges of the front, back, and sides. can do.

(Example) Hereinafter, one embodiment of the present invention will be described based on the drawings.

The container shown in FIG. 1 has a front wall 1, a bottom wall 2, a rear wall 3, and a top wall 4, the walls being made of a continuous fabric of flexible polypropylene, the width of which is 110 mm.
cm, and has square side walls 5 and 6 made of the same material and each side of which is 70 cm. The polypropylene fabric consists of two layers, the outer layer has a weight per unit area of 259 g/sq m and is woven with warp and weft threads of 2000 denier thickness, and the inner layer has a weight per unit area of 40 g/sq m.
Fully coated polypropylene film with S Q m.

The inner layer of polypropylene film is made by a high temperature and vacuum process in contact with the outer layer of woven polypropylene, so that the inner layer is drawn into and fused to the interwoven network of the outer layer. It has become one thing. Although the fabric is waterproof, it also has sufficient gas permeability to allow the pressurized gaseous disinfectant to pass through the container walls and reach the contents.

The side walls 5 and 6 are stitched to the continuous fabric forming the front wall 1, bottom wall 2, back wall 3 and top wall 4 by blanket stitched seams 7 using 5000 denier polypropylene thread. . The ends of this thread extend to the top and bottom corners of the container and are sealed with crimped creep 8.

FIG. 3 is a perspective detail view showing the fastener.

The three free ends of the top wall 4 form a set 9 of a clasp-type fastener with a pull ring 12 and a sliding clasp 11, and the upper end of the clasp 5.1.6 constitutes another set 10 of the clasp-type fastener. ing. The clasp-type fastener preferably has a pair of interlocking opposed teeth, and as such is designated and sold under the designation "No. 10zip".

It has a waterproof tape 13 with a width of 21 mm. Zipper tape is sewn to the container wall and lid using 13 metric nylon. The sliding clasp on the zipper has 12 pull rings for easy pulling.
is added. This is because the container must be closed quickly when the pressure for filling with tobacco is removed.

The tape 13, which corresponds to the end of the movement of the fastener, extends to the outside of the planar shape of the container. Therefore, when the zipper is fully opened, its top wall can be folded completely back to expose the container artificial portion.

The wall of the container, for example the top wall, can be provided with a transparent, open-ended pouch 14 on the outside for containing an identification document. The container can also optionally be provided with packaging plates 15 at the top and bottom.

When empty, the container can be transported in a substantially flat configuration. After folding walls 5 and 6 inward, walls 1 and 3 are folded under bottom wall 2 and top wall 4 is folded back onto wall 3.

In this form, if the packaging plate 15 is removed, the container can be rolled up and secured with springs or bands.

In use, for example, as shown in FIG. 2, in conjunction with the filling sleeve 16 and the compressor 17, the top wall 4 forming the lid is folded back, the sleeve 16 is placed in the container, and the packing plate 15 is removed if necessary. Place it in a designated position. Using the compressor 17, the plump tobacco pile 18 of the sleeve 16 is compressed down to the level of the container. The sleeve 16 is then withdrawn from the filled container. After inserting the optional packaging plate, the top wall 4 is folded and secured by sliding fasteners 9-12.

Prior to transport, the container is disinfected in the usual manner, and a gaseous disinfectant solution penetrates the walls of the container and into the tobacco mass.

In the above example, the outer layer of polypropylene fabric is 1
It may be a polypropylene coating knitted with warp and weft yarns of 800 to 2200 denier and weighing 225 to 275 g/sqm.
It is preferable to use polypropylene yarn of 500 to 5500 denier. For example, packaging boards made of wood or cardboard are used on the top and/or bottom of the container to act as a support when the contents are stacked on the front or back wall, and when empty. The packing board can be removed and the container folded.

Typical sizes for containers according to the invention are at least 80
cm, preferably around 110 cm in length, at least 5
0 cm, preferably around 75 cm wide, at least 35
cm, preferably about 50 cm, and in the best case about 75 cm.

A container of the preferred size described above can hold tobacco weighing on the order of 200 kg.

(Effects of the Invention) The present invention provides a container having the above structure, which can be filled with tobacco using a hydraulic compressor in a substantially conventional manner.

That is, in the present invention, as the best way to suppress the force of compressed tobacco expanding upward and downward in the direction of compression, the top, rear, and front walls are made of a continuous, integral fabric;
Additionally, the side walls are joined along the edges to the rear, bottom, and front wall edges. The closed seams protect against tearing since the tobacco has a slight tendency to spread laterally. Containers made of woven fabrics such as polypropylene fibers allow for substantially deflated packaging of tobacco compressed into a single unit, and can be used many times and are virtually non-destructive. There is no. In particular, it can be returned completely folded to its minimum size and repacked.

Also, if the walls of the container are made sufficiently porous, in a filled container, the gaseous disinfectant can pass through the walls and enter the tobacco to disinfect it. The tightly woven polypropylene fabric is gas permeable and also fairly waterproof, so even if the container is left out in the rain or if the surface gets wet, the contents will not become excessively wet. The walls of the container are made of two thin layers, the outer layer being a rough, wear-resistant material such as woven polypropylene, and the less durable inner layer being a gas-permeable but not liquid-permeable coating of polypropylene. By layering it, you can get better waterproofness.
