Definitions

  • This invention relates to containers for and filled with a plurality of packages having the configuration of a tetrahedron and it is the general object of the invention to provide a new and improved construction which makes it possible to provide a container having a simple four-sided prismatic configuration which has a square cross-section, this container holding a plurality of layers of tetrahedron packages, each layer of which is constituted by a compact arrangement of four tetrahedrons, and the several layers being superimposed each upon the other, to the end of filling the interior of the 'containerwith a minimum loss of unstable space, thereby not only making it possible to use a simply configured container but also to establish an extremely efiicient packing factor for a package of this somewhat unusual configuration.
  • the novel container and packages packed therein are constituted by an elongated container having a four-sided prismatic configuration and which is square in transverse section, the packages being substantially congruent and constituted by elongatedt'etrahedrons each of which is defined by four substantially congruent isosceles triangular sides and having two opposite end edges substantially perpendicular to each other, each two triangular tetrahedron sides meeting respectively along each of said opposite edges at an included angle of about To establish an optimum filling factor in the container, each side of the square.
  • defining the transverse sec tion of the container has a length approximately 1.6 times the length of each of the two opposite tetrahedron edges, and the quotient of the length of each said tetrahedron edge divided by the distance between such edges is preferably from about .75 to .85.
  • Containers for and filled with tetrahedron packages are not broadly new, reference being made in particular to US. Patent No. 2,919,800 granted January 5, 1960 to Harry S. V. Jarund, but container structure according to this patent is of more complex configuration and involves use of packages having a regular tetrahedron configuration only. It cannot be used to eificiently stack or pack tetrahedrons which are elongated as distinguished from regular, i.e. in an elongated tetrahedron, the triangular sides would be isosceles triangles whereas in a regular tetrahedron, the triangular sides would be equilateral triangles.
  • the bottom wall of the container is also required to be at least a truncated portion of a substantially regular pyramid having six sides coordinated respectively to the six sides. of the container which is hexagonal in transverse cross-section as compared with a more simple flat bottom wall for a four-sided container in accordance with the present invention.
  • FIG. 1 is a view in side elevation of an elongated tetrahedron package which is to be stacked, or packed in a container according to the invention
  • FIG. 2 is a top plan view of the container showing one layer of four tetrahedron packages and illustrating the stacking pattern involved;
  • FIG. 3 is a perspective view of the container shown in FIG. 2 having a bottom layer of elongated tetrahedron packages stacked therein.
  • the tetrahedron package 1 illustrated in FIG. 1 is of the kind which is produced from a length of a tubular flexible packaging material by fiat-pressing and sealing transversely the ends of the tube length along narrow end zones to form two end sealing fins 2, 3 substantially perpendicular to each other.
  • the body of the tetrahedron package is constituted by four substantially congruent isosceles triangular sides 4.
  • the base edges of two opposite triangular sides meet along the inner line of one sealing fin 2 at an included angle of about 45 and the base edges of the other two opposite triangular sides meet along the inner line of the other sealing fin 3 also at an included angle of about 45".
  • package 1 which may be a liquid such as milk
  • theshape of the package body may depart slightly from a true geometrical tetrahedron, the package walls bulging slightly outwards as seen on the drawing.
  • the distance H between the inner lines of the two end. sealing fins 2, 3 is greater than the length B of the end seals, i.e. greater than the length of the base of each of the four triangular sides of the tetrahedron. More about this will be said later in the description.
  • FIGS. 2 and 3 show a container in which a bottom layer of four elongated tetrahedron packages each as illustrated in FIG. 1, are stacked or packed in accordance with the invention.
  • This container comprises a square fiat bottom wall 5 and four side walls 6, 7, 8 and 9-extending upwardly from the bottom Wall, these sidewalls defining substantially a straight prism of square transverse section.
  • the bottom layer comprises two oppositely directed, overlapping tetrahedron pairs 1a, 1b and 1c, M respectively, all of which rest upon the bottom wall 5.
  • the two tetrahedron packages In and 1b, and 1c, 1d are aligned and symmetrical to a diagonal plane indicated at 10, common to both pairs, passing through the longitudinal axis and diagonally opposite corners of the container, and engage each other in such plane 10.
  • sides of the tetrahedron packages of each pair opposite to the plane 9 engage adjacent side walls of the container.
  • the sides of one pair of tetrahedron packages 1a, lb engage adjacent container side walls 6 and 7, while the sides of the other pair of tetrahedron packages 1c, 1d engage the other adjacent container side walls 8 and 9.
  • Each pair of tetrahedron packages 1a, 1b and 1c, 1d, respec tively, is thus accommodated in a wedge-like manner in an individual one of two diagonally opposite inner side wall corners of the container, the upright one of the two mutually perpendicular edges of each tetrahedron package of each pair extending substantially along the adjacent container side wall corner edge.
  • the tetrahedron edge angle along this upright edge being substantially 45 as previously described, each pair of tetrahedron packages will have a snug wedge fit in the inner side wall corner of the container which encloses an angle of i.e. about twice the tetrahedron edge angle.
  • each one of the two tetrahedron packages of each pair 1a, 1b and 1c, 1a which constitute the bottom layer in the container will be firmly supported by the bottom wall 5 of the container and the adjacent side walls as well as by the other tetrahedron package of that pair.
  • the tetrahedron edge angle, or rather the quotient of the tetrahedron edge length B and the spacing H between end seals 2, 3 may vary somewhat yet ensuring a satisfactory stacking of packages in accordance with the invention. In practice, it is preferred to establish the value of the aforesaid quotient between limits of .75 and .85. When determining this dimensional relationship, as well as others which are to be later discussed, sealing zones or above-mentioned type have been taken into consideration. These sealing fins project from the body of the tetrahedron package and are an inevitable result in most methods of producing tetrahedron packages.
  • the two oppositely directed pairs of tetrahedron packages of the bottom layer are placed within the container in overlapping relationship.
  • one pair 1a, 1b rests in part on the other pair 10, id but one tetrahedron package of a first pair might as well rest in overlapping relationship upon that tetrahedron package of the second pair situated on the same side of said diagonal plane 1% common to both pairs, the other tetrahedron package of the second pair resting in overlapping relationship upon the other tetrahedron package of the first pair.
  • the sec-nd layer to be inserted in the container in accordance with the stacking pattern of the invention will also comprise two oppositely directed, overlapping pairs of tetrahedron packages.
  • the pairs of tetrahedron packages of the second layer will rest upon the upwardly facing triangular sides of the tetrahedron packages of the bottom layer, and in each such pair the two tetrahedron packages will be aligned and symmetrical to a diagonal plane 11 common to both pairs through the other diagonally opposite corners and longitudinal axis of the container, the plane 11 thus being perpendicular to the symmetry plane it) associated with the bottom layer of four tetrahedron packages.
  • the two tetrahedron packages of each pair which constitute the second layer will engage each other in the second diagonal plane Hand triangular sides of the packages opposite from the diagonal plane 11 will engage adjacent side walls of the container.
  • the general stacking configuration of the second layer of tetrahedron packages will be generally the same as that of the bottom layer of packages, the only dilference being that the respective planes of symmetry lit and 11 are perpendicular to one another.
  • the third layer will have the same orientation as the bottom layer, i.e. its plane of symmetry will coincide with plane 1th of the bottom layer.
  • Any fourth layer will have the same orientation as the second layer, its plane of symmetry coinciding with the symmetry plane 11 of the second layer.
  • the stacking pattern according to the invention has the feature that each layer of four tetrahedron packages has the same general stacking configuration, and that the various layers are placed each upon the other in such manner that the planes of symmetry of successive layers are alternately one and the other of two diagonal planes through the corners and longitudinal axis of the container.
  • the two overlapping tetrahedron pairs of superimposed layers having coinciding planes of symmetry i.e. layers one, three and five, or layers two, four and six, etc. have alternatively one or the other of two overlapping arrangements.
  • two tetrahedron packages adjacent one side wall corner of the container may partly overlie the other pair, while in the next succeeding layer, that tetrahedron pair adjacent the same side wall corner of the container may underlie the other tetrahedron pair of the latter layer.
  • the overlapping arrangement of equipositioned layers may alternate similarly, so that each tetrahedron of one layer overlies or underlies another tetrahedron of that layer, while the corresponding tetrahedron of the second next layer underlies, or overlies, respectively, the corresponding other tetrahedron thereof.
  • the width A of one side of the squarely configured container should exceed the distance H previously referred to in order to permit insertion of the tetrahedron packages 1 in the container in the improved stacking pattern.
  • Optimum stacking results have been obtained by dimensioning of the container in such a way as to yield a transverse container si-de width A equal to 1.6 times the length B of the base of each triangular side of the tetrahedron.
  • Table 1 Number Container Number of layers of tetraheight L in hadrons length B 4 1X13 8 1 3X13 12 2 3 B 16 2 6X13 20 3 6X13 24 3 9X13 From the above Table 1 it will be apparent that a container having stacked therein multiples of two layers in accordance with the invention will have its interior volume or capacity well utilized. However, for practical reasons, it is preferred that the number of layers of four tetrahedrons each should not exceed four for the reason that use of a greater number of layers will result in a container whose height L will be excessively great as compared with the dimensions of its squarely configured bottom wall.
  • a package for and filled with tetrahedron packages as defined in claim 1, comprising a multiple of tWo further layers of said tetrahedrons, the two pairs of tetrahedrons of each of said further layers being disposed similarly to those of said bottom layer and said second layer, said diagonal planes through the container axis alternating for successive layers.
