In a plastic case for individual bottles or bottles in cardboard carriers, the bottles are positioned slightly spaced from one another in straight lines by columns projecting up from the bottom of the case. Except at ends of the case, the columns are arranged in pairs with the two columns of a pair spaced apart to receive the sides of bottle carriers between them. At the ends of the case, there are single columns spaced from the end walls to receive the sides of bottle carriers. Each column is of T-shape or Y-shape in cross section, formed of two sides joined in an acute angle. Each side is formed of two wall portions disposed at an obtuse angle to one another. At the three corners of each column there are rounded beads which engage cylindrical surfaces of the bottles to position them. On the side walls in line with rows of columns there are rounded beads on inwardly projecting ribs. At the corners of the case there are strong double wall columns which constitute load-supporting elements when the cases are stacked.

1. A rectangular plastic bottle case for individual bottles and bottles in bottle carrier of sheet material, comprising end walls, side walls, a bottom and means for positioning bottles in the case with the bottles closely spaced in straight lines parallel to the end walls, said bottle positioning means comprising columns projecting up from the bottom of the case, said columns being arranged in straight rows of pairs of columns, the two columns of each pair being spaced from one another to provide between them aligned spaces to receive a side of a bottle carrier, said columns being open V-shaped in cross-section, each of said columns being formed of two sides integrally joined with one another in an acute angle having its apex directed away from the space between the two columns of a pair, each side being bent inwardly along a longitudinal median line to provide two integral elongate wall portions disposed at an obtuse angle to one another, each column having three corners of which two are at edges of said sides adjacent said space between the two columns of a pair and one is at the apex of the acute angle in which the two sides join, and an enlarged rounded bead at each of said corners imparting strength to said columns and adapted to engage and precisely position bottles in said case. 2. A plastic bottle case according to claim 1, in which there is a long narrow median opening extending longitudinally in each of said sides of said columns. 3. A plastic bottle case according to claim 1, in which along each end wall of the case there is a row of like single columns in line said pairs of columns in said case and spaced from the end walls to provide a space for receiving a side of a bottle carrier with the apex of each column directed away from said space. 4. A plastic bottle case according to claim 1, in which along each side wall of the case there are pairs of vertically extending ribs projecting inwardly from said side walls, the ribs of each pair being equally spaced from a center line of said aligned spaces between columns. 5. A plastic bottle case according to claim 1, in which each of said columns is closed at its upper end with an inclined roof which slopes downwardly from said space between columns to said apex. 6. A plastic bottle case according to claim 1, in which at each corner of the case there are hollow double wall columns with an outer wall forming a portion of an outer wall of the case and an inner wall forming a portion of an inner wall of the case in corner portions only of the case, said columns extending above and below intermediate single thickness portions of side walls of the case. 7. A plastic bottle case according to claim 6, in which said hollow columns at the corners of the case are closed at their upper ends by flat tops which are offset inwardly by the thickness of said outer and inner walls of said corner columns so as to be received in lower ends of said hollow corner columns of a like superposed bottle case to maintain stacked bottle cases in stable condition. 8. A plastic bottle case according to claim 3, in which the bottom of said case comprises circular webs supporting said pairs of columns, semicircular webs supporting said single columns and straight webs connecting said circular webs and semicircular webs. 9. A plastic bottle case according to claim 1, in which said columns are spaced from one another to so that said enlarged rounded beads engage bottles in said case to position bottles in said case with a space of 0.5 to 1.5 mm between bottles. 10. A bottle packaging comprising bottles in bottle carriers and a rectangular plastic bottle case containing a plurality of said carriers with bottles therein, said bottle carriers being formed of a rectangular sheet of material bent to provide only a bottom and sides, the ends of said carrier being open, and said bottle casing comprising end walls, a bottom and means for positioning bottles in the case with the bottles closely spaced in straight lines parallel to the end walls, said bottle positioning means comprising columns projecting up from the bottom of the case, said columns comprising straight rows of pairs of columns parallel to said end walls, the two columns of each pair being spaced from one another to provide between them aligned spaces to receive sides of bottle carriers, and straight rows of single columns inside said end walls, said single columns being spaced from the respective end walls to provide between said single columns and the respective end walls spaces to receive sides of bottle carriers, each of said columns having three corners of which two are adjacent said respective spaces and the third is on a line bisecting and perpendicular to a line connecting said two corners, and enlarged rounded beads on said corners adapted to engage and position bottles in said case, said columns being spaced from one another to position bottles in said case with a space of 0.5 to 1.5 mm between bottles, the bottoms of said bottle carriers having openings to receive said columns of the case. 11. A bottle packaging according to claim 10 in which each of said columns is formed of two concave walls extending respectively from said two corners to said third corner and integrally joined with one another at said third corner, the facing sides of two columns of a pair being open. 12. A bottle packaging according to claim 10, in which said bottle case comprises a hollow column at each corner, each of said hollow columns comprising an outer wall and a curved, concave inner wall, side walls of said case between said columns being single thickness. 13. A bottle packaging according to claim 12, in which each of said bottle carriers comprises flaps at the ends of the bottom of the carrier, which flaps are folded up and pressed against the cylindrical part of end bottles so that corners of said bottle carriers are rounded. 14. A plastic bottle case according to claim 3, in which said case has four rows of said pairs of columns parallel to ends of said case with three pairs of columns in each row, and three of said single columns along each end of the case. 15. A bottle packaging according to claim 10, in which said bottle case has four rows of said pairs of columns parallel to ends of said case with three pairs of columns in each row, and three of said single column along each end of the case.
