Description

By the cake of the sheet material manufacturing of being cut into monolithic and the deployable box of cake

The present invention relates to a kind of extensible box that is used for adorning cake, cake or similar articles, can box when small part flattens to wherein putting into or therefrom take out article, this box comprises a bottom, its each sideband has hinged joint, when hinged joint altogether the time, just form box backplate and box item all around, also form a handle simultaneously, whole box is to make from cardboard that is cut into monolithic or similar material.

Polytype collapsible boxes that offers the user of putting down that made by cardboard, folded is arranged as everyone knows.Especially, people know has some to be used for adorning the common box of cake.This box comprises by one three side the complete part that the end on limit constitutes; Thereafter sideband has lid.For folded flat, the limit of its end and lid will be folded up along some fold lines.

The advantage of this cake box that uses in decades is, when adorning article to be packaged in print, box can be folded gentle expansion.Because the existence of its sidewall, and because the box wall of each side is bonded together mutually, and when launching, this box is enough strong, thereby can fasten belt and can propose the belt carrying.

But this box also has some shortcomings.Wherein serious problem is, there is certain height on described limit, and the existence of the limit end of in other words itself is exactly a shortcoming.In fact, in order to put into article in such box, especially frangible article just must clip sliding from top to bottom and put such as cake with anchor clamps, and the existence on limit makes and can not put down to wherein putting into article.

When unpacking, there is same inconvenience.

Also described a kind of box among the document FR8813968 on October 26th, 88, it is a type recited above, but can resist extruding to a certain degree.

But in many cases, box must be not anti-extrusion, and it just is subjected to tractive because it otherwise be to be placed on the plane (such as desk, sales counter), or be to hold in the palm or carrying from beneath with its handle with hand.

Because this box is wanted resistance to compression, its structure will be carried out certain training with regard to more complicated to the user when packing.

Also have a kind of cake packaging to be called " tower packing " at last.It has a square cardboard, constitutes the bottom of dress cake, with a piece of paper its circle is lived again, forms a pyramidal cover, and this cover is fixed below the bottom by adhesive tape.The top closure of Pyramid is pricked with a strap, so that it can carried.

This packing implements also needs cooresponding technical ability.

This packing is also somewhat expensive, because need large-area paper.

The objective of the invention is to remedy above-mentioned shortcoming, the box of a kind of packing and carrying breakables is proposed, described breakables are such as being cake, cake, or the article of wishing in packing or box can be opened or flatten when taking out, this box volume is little, in light weight, the more important thing is to be easy to close, also be easy to open.

For this reason, the present invention relates to the box of the above-mentioned type, it is characterized in that:

-bottom is tetragonal,

Each limit of one bottom is connected with two main hinged joints and two secondary hinged joints, links to each other by fold line both sides relative respectively with the bottom,

-hinged joint unfolded, to the top of hinged joint, the width of hinged joint broadens and narrows down from the limit of bottom, thereby its edge protrudes,

-main hinged joint is connected with a tongue piece that has sealing and grip function, links to each other with hinged joint by a fold line,

-secondary hinged joint has a longitudinal opening in its end, is used for when main hinged joint is joined together by its tongue piece to wherein inserting tongue piece,

One secondary hinged joint top is butted on the edge of main hinged joint to the curved edge of main hinged joint, and is hooked on the tongue piece by its opening.

Cartridge bottom shape of the present invention is tetragonal, that is to say it is rhombus or parallelogram, especially oblong or square, seems very simple, assembles up also very simple.Only need two main hinged joints are lifted, they are adorned, then the bending of one of two secondary hinged joints is arrived on the edge of two main hinged joints with its tongue piece; Then, the end of the band opening of secondary hinged joint is passed through above two tongue pieces, so just hooked secondary hinged joint, so that whole box can keep its shape.

The final step of finishing packing is another secondary hinged joint that closes, and is about to it to the edge of the opposite side of two main hinged joints natural torsion, and the end that makes its band opening is passed through above two tongue pieces that assembled in the same way.

So just finished packing, and packing is a self-supporting.This is because two main hinged joints have elasticity on the one hand, does not have fold line, and in the respective edges of cartridge bottom with connect between the fold line of hinged joint and tongue piece, its curvature is continuous and level and smooth.

According to the tetragonal shape that constitutes cartridge bottom, and by the difference of shape of hinged joint of decision, when hinged joint flattened, the fold line that always is positioned at fitting plane between tongue piece and the hinged joint can be parallel to the fold line that connects hinged joint and bottom, also oblique with it.

According to the present invention, when confined state, secondary hinged joint encases the edge of main hinged joint, and outstanding to some extent.Because the elasticity that has of above-mentioned joint, main hinged joint trends towards its tongue piece is sticked up, and the secondary hinged joint that is hooked in the two tongue piece both sides that lump together is just by stretching; So just formed a kind of shape of the best, wherein, secondary hinged joint almost completely encases by the determined profile of main hinged joint that is in confined state.

Should be noted that main hinged joint is subjected to the squeezing action of secondary hinged joint.Main hinged joint is not flat, and form a well-regulated surface-when being parallelogram shape in the bottom, this surface is a face of cylinder, its bus is parallel to the fold line between hinged joint and bottom, because previous reasons, main hinged joint just constitutes strong strut rail parts beam part in other words, can support secondary hinged joint.

Secondary hinged joint is subjected to the effect of tension force, and they are subjected to the elastic force effect of main hinged joint generation and are tauted in its shortest position, and main hinged joint has the trend of its tongue piece of perk.

Above-mentioned whole assembly has formed a kind of structure of coordinating very much, when box is in suspension status, that is to say that it is strong that box still keeps when carrying it with its tongue piece.

When box was put down, the elasticity of main hinged joint had been avoided subsiding of box.Secondary hinged joint colluding on tongue piece hung and produced certain squeezing effect, makes winner's hinged joint tensioning.

The present invention also has other useful feature:

The quadrangle of-bottom is a parallelogram, particularly rectangle, especially square;

Corresponding hole is arranged on-the tongue piece.

The present invention is described with reference to the accompanying drawings in further detail, in the accompanying drawing:

-Fig. 1 is the block diagram of the deployable box that closes of a part,

-Fig. 2 illustrates the state that the box among Fig. 1 closes fully,

-Fig. 3 is for making the planar view of the sheet material that a deployable box cuts, and wherein, the bottom of box is a square,

-Fig. 4 illustrates sheet material among Fig. 3 along a situation that diagonal line is folded up of bottom,

-Fig. 5 is to three steps of the schematically illustrated box closure of Fig. 7,

-Fig. 5 is the first step, two the main hinged joints that close,

-Fig. 6 is one of closed two secondary hinged joints on two main hinged joints,

-Fig. 7 is closed second secondary hinged joint on main hinged joint that has assembled and secondary hinged joint,

-Fig. 8 is the lateral plan (left view) of box among Fig. 7.

Referring to Fig. 1 and Fig. 2, the present invention relates to a kind of extensible box that is used for holding and carrying breakables, breakables are such as being cake, cake, or the article that need do similar disposal and carefully look after.

This box is used for filled with product under flat or part deployed condition, is providing items under open mode or under the state that launches to small part.

Fig. 1 shows the state that a kind of part is launched, or perhaps the state of box when closed fully as yet, and Fig. 2 then shows the box of complete closure.

Comprise that by cutting the box that flexible cardboard or similar material realize a bottom 1, its edge are connected with 2,3 and two secondary hinged

joints

4,5 of two main hinged joints.

Usually, the shape of bottom 1 is tetragonal, such as parallelogram.More particularly, the shape of bottom is rectangular, especially square.

Main hinged

joint

2,3 and secondary hinged

joint

4,5 are linked to each other with the bottom by

connection lead

6,7,8,9.

As shown in Figure 3, be shaped as under the foursquare particular case in bottom 1, the shape of main hinged joint and secondary hinged joint is such, and promptly the

limit

6,7,8,9 from the bottom upwards broadens, reach certain width after, narrow again in direction again towards its end.

In Fig. 3, the tetragonal length of side of bottom 1 is a and a1, and the widest part of hinged joint is b and b1.

In other words, the edge 21 of hinged joint 2 has the curvature of evagination, and is shrinking again on the direction of end 22.

Edge 41 for hinged joint 4 is same situations, is curvilinear figure, shrinks to end 42.

Same description is applicable to other hinged

joint

3 and 5.

In addition, the shape of main hinged

joint

2,3 is normally identical, perhaps is similar at least.For secondary hinged

joint

4 and 5 equally so.1 is parallelogram in the bottom, and especially under rectangle and the foursquare situation, main hinged joint is identical in twos with secondary hinged joint.In the bottom is under the tetragonal situation of non-parallelogram, and hinged joint is and preceding similar shape, can push in some way or " inclination " shape shown in Figure 3 and obtaining.

Under the situation about being made of the parallelogram of quadrangle or non-rectangle in bottom 1, width b, b1 always are parallel to that connection lead 6,7,8,9 between hinged

joint

2,3,4,5 and the bottom 1 records.

The

bent limit

21,31,41,51 of hinged joint is converx in the part that is positioned at bottom margin, so that the shape of its part that is right after narrows (narrowing effect also can realize along a convex curve) towards end direction.

The end of main hinged

joint

2,3 is

tongue pieces

10,11, and the latter links to each other with main hinged

joint

2,3 by a

connection lead

12,13.

joint

10,11 respectively has a

hole

17,18, is convenient to hold, and can tethers rope or tag line.

Should be noted that as described belowly, when main hinged

joint

2,3 closed,

tongue piece

10,11 fit together mutually, formed a cylindrical or tubular surface, therefore made bottom 1 become strong, no longer can be folding along fold line 16.

In further detail aforementioned components integral body is illustrated by Fig. 5,6,7 below, the outward appearance of box is the same with block diagram illustrated in figures 1 and 2 among the figure.

Before packing, what the user took usually is to be folded into the sheet material of state as shown in Figure 4.From this state, sheet material is opened, flatten, the article that will pack are placed on the bottom 1 then, and the

tongue piece

10,11 of the main hinged

joint

2,3 that closes must press down hinged

joint

2,3 when closing and makes it crooked.Like this, just make hinged

joint

2,3 become crooked shape from its aspect.

Then, one of secondary hinged joint, for example hinged joint 4 to 21,31 tractions of the edge of main hinged joint, are made it to open 14 with it and slide on

tongue piece

10,11, make and open the back that 14 edge arrives
