CARTON BOX MADE OUT OF SEVERAL BLANKS

Abstract: The invention refers to an economical carton box for packing and transportation of products that can consist of many pieces of corrugated board or solid paper so as in each case and for each side separately the arrangement of the paper's waves is to be indicated. For such an economical carton box the extensions (F1, F2,..., F6) of sides (A1, A2, A3) turn internally by 90 DEG so as to be glued with the outside part of the small sides (A4, A5) accordingly and the F7, F8 to base A2. The extensions (N1, N2) rotate and glue externally to sides (A4 and A5) while columns (K1, K2, K3, K4) are formed at the small sides. When the height of the sides (A1, A3) is equal to the height of the carbon box then the extensions (N1, N2) constitute the covering of the carton box. The projections (P1, P2, P3, P4) of sides (A4 and A5) fit into slots (E1, E2, E3, E4) accordingly during the piling of the boxes.

Description: CARTON BOX MADE OUT OF SEVERAL BLANKS The invention is referred to an economical carton box which is at the same time very resistant and useful to packing and transportation of agricultural and industrial products. Till today many boxes are known to be used in packing and transportation of agricultural and industrial products which are formed by a single paper surface. The blank of this paper which is usually large has as a consequence to create problems during the production of the corrugated board at the corresponding industries. Each time the appropriate combinations should be done as far as the dimensions are concerned in order to decrease the remains of the corrugated board which is not always attainable. Also the arrangement of the waves of the corrugated board out of which a carton box is constructed is as a matter of fact, made towards one direction resulting that certain sides of it appear to lack resistance not because the quality or the paper weight are not satisfactory but due to the inappropriate arrangement of the waves of the corrugated board. The advantage of this invention is that a carton box or tray can be constructed by different pieces of corrugated board or solid paper that are held together with glue. In this way the combinations in the corrugated board or solid paper productive lines become much easier since the blank of the papers is smaller and moreover at each side of the carton box, papers with the appropriate paper arrangement can be used and thus we finally have a very economical and resistant carton box. Figure 1 shows the blank of the economical carton box according to the invention in case that all the carton box's sides and its base are consisted of different pieces of paper and triangular columns are formed in its corners and inner paper refolding are made in the large sides.

Applications of the inventions are described below. The interrupted lines in all Figures represent the folding of the paper material and the uninterrupted ones represent its cuttings. The reference regards the one fourth or one half of the carton box for each case because of its symmetry against both the horizontal and vertical axis that go through its center. Each paper surface may have different thickness but in case at issue this will be considered to be the same with the others and equal to p. a) Figure 1 shows surfaces of corrugated board or solid paper that are being cut and folded according to it so as the sides A1, A2, A3 of the carton box can be formed as well as their extensions F1, F2 , F8 of fi length, the Nl, N2 of ni length, the Dl, D2, D3, D4 of di width, the small sides of the carton box A4 and A5 with the triangular columns K1, K2, K3, K4, which are formed by a relevant refolding of the 1,2,3 surfaces a.b.c length and equivalently the projections PI, P2, P3, P4. Also at all paper surfaces relevant cuttings are made in order finally to arise the slots E1, E2, E3, E4 of a carton box as Figure 12 shows and whose dimensions' are equivalent to those of the projections PI, P2, P3, P4 so as during the piling of the carton boxes their appropriate fixing can be accomplished. According to the present invention at A4 and A5 sides the surfaces 3 of c length rotate by 45° externally (in case the triangular column is isosceles), also the surfaces 2 of b length rotate at 135° internally and finally the surfaces 1 at length a rotate internally by 90° resulting that the inner side of surfaces 3 touch the sides A4 and A5 and thus the triangular columns K1, K2, K4, K4 are finally formed. Also surfaces F7 and F8 of A1 and A3 sides equivalently glue together with A2 side in such way that a single rectangular parallelogram is formed with A2 side usually above the surface F7 and F8. The dimensions of this single surface are [W1+2(H1+ni)]x(L1+2fi) The A1 and A3 sides rotate internally by 90° and afterwards the A4 and A5 sides are put vertically towards the A1, A2, A3 surfaces with the projections PI, P2, P3, P4 placed upwards and in such position that the surfaces F1, F2, F3 and F4, F5, F6 when rotated internally by 90° they are touched with A5 and A4 sides so as the gluing together of all the carton box's sides can be finally accomplished by the insertion of the glue. Afterwards the N1, N2 sides rotated internally by 180° are glued together with A1 and A3 sides equivalently while the D1, D2, D3, D4 dimensions are glued on the small sides of the carton box and particularly on their surfaces 2. The carton box that is formed by this way has external dimensions with length L=L1+2p, width W=W1+2p=W2+4p and height H (without estimating the height of projections PI, P2, P3, P4). With accordance to the ventilation demands of the packed products an airing gup is formed which is defined by the difference of height H of the carton and sides A1 and A3 with high H1, that means (H-H1). Regarding the fi and ni lengths of the extensions Fi / i=1,2, ..., 8 and Ni / i=1.2 , fi >0 and 0< ni < H1-p valid. Also 0< di < b+c when ni >0. The extensions F7, F8 of sides A1, A3 accordingly can be erased by them and become extensions of base A2 of the carton box as well as the F2, F5 which are extensions of A2 can be erased and become extensions of sides A5 and A4 accordingly. b) Figure 2 according to the invention shows surfaces of corrugated board or solid paper which are being cut and folded accordingly to this, so as during their formation, Figure 21, to be arise the box of Figure 22. According to the present invention at A4 and A5 surfaces 3 rotate orderly, internally by 135°, then surfaces 2 turn internally by 135° and finally surfaces 1 rotate internally by 90° with the consequence the outer side of surfaces 1 to be touched and glued with A4 and A5. In this case ni =0 and for length c valid 0<c< v lb^a-p) 2 ] c) Figure 3 according to the invention shows surfaces of corrugated board or solid paper which are being cut and folded accordingly to this so as during their formation, Figure 31, to be arise the box of Figure 32. In this case at sides A4 and A5 the columns K1, K2, K3, K4 that are formed become by the orderly external rotation of surfaces 4 by 90°, the internal rotation of surfaces 3 by 90°, of 2 internally by 90° and finally of 1 internally by 90°. For lengths a.b.c.e c=a-2p, b=2p, 0<e< (W2/2-2p) valid. Especially when e=0 then 0<c< a-2p. d) Figure 4 according to the invention shows surfaces of corrugated board or solid paper that are being cut and folded according to this so as during their formation, Figure 41, to be arise the box of Figure 42. In this case at A4 and A5 the rotations of surfaces 1,2,3,4 are taking place so that columns K1, K2, K3, K4 to have the shape of a rectangular trapezium and attached surface the inner side of 4. Here valid a>2p, b≠O, c>a-p. e) Figure 5 according to the invention shows surfaces of corrugated board or solid paper that are being cut and folded according to this so as during their formation, Figure 51, to be arise the box of Figure 52. In this case at A4 and A5 the rotations of surfaces 1,2,3,4 are taking place so as columns K1, K2, K3, K4 to have the shape of a rectangular trapezium and attached surface the external side of 4. Here valid a>2p, b≠O, 0<e< (b-p)+v [(c-p) 2 -(a-p) 2 ]. f) Figure 6 according to the invention shows surfaces of corrugated board or solid paper that are being cut and folded according to this so as during their formation. Figure 61, to be arise the box of Figure 62. According to the invention the surface 2 turns internally by 90° against the 1 and the 1 internally by 90° too. In this case a=2b and 2b< W2 valid. In case that surfaces A4, A5 are the same to each other but none symmetrical to the axis which comes vertically through their center and valid one out of a to be equal to 2p and the other equal to 3p then the sides A4 and A5 are formed by three successive sheets of paper and then valid (W2/2) <b< W2. On base A2 are formed grooves 01 and 02 so that projections PI and P2 fit to them during the boxes piling. When the high of projections PI and P2 is bigger than p then we have to cut equivalent slots E1 and E2 to the sides A5 and A4 g) Figure 7 according to the invention shows surfaces of corrugated board or solid paper that are being cut and folded according to this so as during their formation, Figure 71, to be arise the box of Figure 72. In this case the extensions 5 of A4 and A5 rotate internally by 90° and afterwards the 6 internally by 90° too so as finally to be glued with A4 and A5 conditioning that H1+j<H+2p. Then r<a also valid. When H1=H-p then surfaces 6 glue together with sides A1 and A3 and r≠O and j<H1 valid. Also according to the present invention sides A1, A2 and A3 can be consisted by a single surface of paper as Figure 1 shows. h) Figure 8 according to the invention shows surfaces of corrugated board or solid paper that are being cut and folded according to this so as during their formation, Figure 81, to be arise the box of Figure 82.
