Description

Packaging unit as a plurality of square frame shape cardboard cases of packing

The present invention relates to a kind of packaging unit, it comprises:

Many arrangement in parallels become number row's rectangular cardboard box, and each row nestles up discharging mutually, and first and last cardboard case of each row forms first and last end face together respectively;

One is trapped among the outer wrapping plate of cardboard case in a row, and this wrapping plate forms the bottom surface, relative side, and the end face relative with the bottom surface along the backfin line pressure folding that is parallel to cardboard case in a row.

This wrapping plate seals number row with these cardboard cases.

People are from US-A-4, and 555,979 have known this packaging unit.

In the known package unit, for example, two row's cardboard cases are placed on the flat board of margin of uplift, second flat board that is filled with cardboard case then can be placed on the former top.Wrapping plate surrounds this packaging unit on four limits, and one of this four limit is the end of first flat board.Wrapping plate seals this packaging unit with the method that clamps.Can prevent the flat board osed top wrapping plate that slips away like this.Margin of uplift on the flat board and wrapping plate prevent that jointly from then on indivedual cardboard cases from deviating from the packaging unit.

The advantage of this known package unit is, owing to use wrapping plate, required packing are wanted much less with comparing with outer cardboard case, and cardboard case all can be contained in the packaging unit securely.

Though, to compare with traditional packaging unit, a large amount of packing can be saved in above-mentioned known package unit, also need use many packing eventually, and at the remaining appreciiable material in the back of unpacking.

One object of the present invention just provides a kind of at the first section described packaging unit that also can further save packing of this paper.

According to the present invention, this purpose is with there being the sideband of certain width to realize, this sideband is along the bottom surface of wrapping plate, side and end face extend and link to each other, this sideband is close to first and last end face, interfix between sideband, whereby, wrapping plate with all be positioned at first or the cardboard case of last end face clamp and can fit like that.

The advantage of packaging unit of the present invention is without any need for flat board, because of being integrated in the wrapping plate with dull and stereotyped function of clamping cardboard case.This not only can save packing, also can simplify logistic work.

Because of sideband generally can be rather narrow, for example, its width can be identical with the width of the margin of uplift of above-mentioned known flat board, for example several centimetres, for example 2 to 4 centimetres,, promptly on wrapping plate, do not need to print any information with the article in the sign packaging unit so packaging unit also has an advantage, because the end face of this element opens wide basically, can show the cardboard case of being adorned.

Whether sideband and wrapping plate are linked to be holistic another advantage, firmly make wrapping plate clamp cardboard case in a row, or be clamped to what degree, and be unimportant to the strong packing of cardboard case.

Another advantage of this packaging unit is that it has fabulous stacking performance, because of its several all can be as planar support surface.

In addition, interfix and near those sidebands of first end face and near those sidebands of last end face, when wrapping plate is shaped by its blank, on the side is folded to together position, need not be by means of end face and side fixedly come enclose plate itself.

In the preferential embodiment of this packaging unit, end face is divided into first and second parts, and each part links to each other with corresponding side along the backfin line.Seam between two parts for example is positioned at end face central authorities, the middle part between the side.Two parts of end face can abut against seam mutually.Usually, the packaging unit good rigidly of this seam is arranged, so that during normal use packaging unit, this seam is difficult to open.If one row's cardboard case is arranged in seam region, extend under first and second parts of end face, then this packaging unit also has quite high torsional rigidity, and promptly first and second parts of end face are in not displacement mutually of seam.

In this embodiment, when end face is vertically placed, and with the side during as the bottom surface, end face also can bear the power that the Unit second on the last packaging unit is acted on that is placed on well.If requirement is arranged, can be provided with intermeshing tooth at the first and second part places of end face, insert as charge into wrapping plate inside.This tooth can prevent two parts of end face in the mutual displacement of seam, thereby increases the torsional rigidity of packaging unit.

In a certain embodiments, end face is divided into first and second parts that link to each other with corresponding side, and the width W of the size of first and side sideband is suitable.In a preferential embodiment, second portion has the lug that stretches into wrapping plate.This lug can prevent that second portion slides into first under pressure.Therefore this lug guaranteed first and second portion mutually near, in further modification, there is tongue piece at the sideband position of stretching to the second portion under the associated side sideband.This tongue piece has increased the torsional rigidity of packaging unit.Generally do not need to adopt sticking method at lug and tongue piece place.

In another embodiment, end face also is divided into first and second parts, but space one distance, more particularly their size is all suitable with side sideband width.This embodiment can make the end face of most of cardboard case packaging unit not be capped, and this can further save packing.

One or more parts that it should be noted that end face have a certain size, promptly from the edge to the distance the adjacent folds line, suitable with the sideband width.In a certain embodiments, in fact, two perforated lines are arranged in the bottom surface, keep certain distance mutually, in the other extension of backfin line, and extend to continuous sideband.Particularly the distance between perforated lines and corresponding backfin line equals the width of side sideband.End face has corresponding perforated lines as far as possible.If the existing size W of an end face part or several parts then just can not or not need this perforated lines really on these positions of end face.

The advantage of this embodiment is that packaging unit is easy to open, and the sidewall that sideband is arranged is each self-forming one flat board, is illustrated in together on the table top with relevant cardboard case, and does not need other measure.This embodiment also has additional advantage, after promptly this unit is opened, have relevant sideband continuous part only a part of bottom surface and may be waste material by surplus by a part of end face, and these materials are easy to be crushed and make waste product and handle.

Cardboard case in a row can one or more layers be parallel to the bottom surface arrangement.Every layer can comprise two or more rows.Yet the fact that wrapping plate blocks each cardboard case that is positioned at an end face with sideband means that every layer could be more than two rows if the number of plies is no more than when two-layer.If there be the 3rd layer, all blocked by sideband with regard to the cardboard case of not all interlayer.If it were not for must be outside packaging unit observable words, deviate from the packaging unit that cardboard case will never be opened.Similarly, for same reason, if every layer of no more than two row, could be in packaging unit more than two-layer.

As long as each cardboard case that is positioned on the end face blocks by a sideband, in packaging unit, also multilayer can be arranged by the end face dimerous of space, top one distance, and every layer of maximum two row, or have two-layer and every layer number row is arranged.

Yet more noticeable is that every layer of several layer of having only two rows are arranged in the unit.The advantage of this unit is after the packing between the perforated lines are torn off, can obtain occupying two flat boards holding cardboard case of a settling position.Like this, cardboard case entirely by the slab supporting medium that so obtains together.

Volume and quality that cardboard case number among one row and the row's number in a packaging unit and the number of plies depend on cardboard case also depend on the character of loaded article, determine the laying state of cardboard case thus definitely.Described factor also determines the quality of materials as wrapping plate.And for the personnel that are proficient in packing technique, it is simple selecting suitable parameter under any specified criteria.

Be more suitable for packing one or two electric lamp bulb, for example filament bulb in each cardboard case by packaging unit of the present invention.Generally, bulb quality is compared much smaller with their volume.But their volume is still less, so, in a packaging unit, with method easily, can be with a considerable amount of bulbs, for example in the cardboard case that 40 are packaged in same number or half.

Better suited wrapping plate material is carboard such as double-ply, thin corrugated sheet, half corrugated sheet or corrugated boxboard.The backfin of corrugation or the stupefied carboard of half-watt is preferably along the horizontal expansion of backfin line.
