Definitions

  • ATTORNEY PACKAGING CONTAINER This invention relates generally to a plastics packaging container, and more specifically to a type of container wherein the product to be contained is supported in suspension within thin walls which have been joined to form the contour of the product.
  • This invention herein provides a packaging container thermoformed out of one sheet of thermoplastic material to receive or contain an article or articles in suspension within four separate thin walls of cavities, the four separate cavities having been formed in the top of each of the separate projections so as to constitute the complete contour or sometimes the sustaining walls larger than the contour of some parts of the article or articles, when this container is folded up at the lines separating these projections, to construct a handy form of a box with square or rectangular walls of two vertical sides enhancing the structural strength of the container as a whole, and a sheet of plastics or of cardboard also'foldable, which is attached to one end of the flange part of this container and folded over the already folded body of container as its external cover.
  • the foremost feature of this invention is that it provides a packaging container of new design concept of high protective performance supporting the commodity in suspension.
  • This packaging container can be stored or transported in stacks, that is to say, nested one onto another without occupying its whole dimensional space. It is hardly necessary to mention here that this feature is very important for the users of packaging materials.
  • FIG. 1 is a view in perspective showing the basic concept of this invention in its preliminary stage, wherein a sheet of thin gauge plastics is formed after in accordance with the contour of four triangular projections that are aligned without clearance between them, this being the form of a square block diagonally cut into four parts and extended in alignment.
  • FIG. 2 is a view in perspective of the formed plastic sheet folded up into the original form of a square block with four triangular cavities accessible from the outsides.
  • FIGS. 3 & 4 are respectively unfolded and folded views in perspective of a variation in the basic concept of this container wherein two of the four projections are of trapezoidal form in cross section.
  • FIG. 5 shows in perspective view the four separate triangular projections each provided with a cavity on the top in the form of one quarter of the contour of a glass cup so that, when folded up, a complete contour of a glass cup is formed as shown in FIG. 6 which is its horizontal cross section.
  • FIG. 6 is a cross section through the folded up container of FIG. 5, taken at right angle to the axis of the cup.
  • FIG. 7 is an elevational view of a formed plastics container for a square bottle to be contained as an example.
  • FIG. 8 is an elevational view of the container of FIG. 7 as viewed from the top in FIG. 7.
  • FIG. 9 is an elevational view of one of FIGS. 7 and 8 as seen from the left and formed on the top of a triangular projection.
  • FIG. 10 is a cross-sectional view ofthe container of FIGS. 7- -9 is folded up.
  • FIGS. 11 and 12 are respectively, end and plan views of a container with multiple cavities to pack six glass cups with conical side walls.
  • FIGS. 13a, 13b, 13c and 13d show respectively partial elevational views of each cavity to be formed on the top of four separate triangular projections as seen from the left in FIG. 12.
  • FIG. 14 is an elevational view when the container of FIGS. 12, 13a, 13b, 13c and l3dis folded up.
  • FIGS. 15 and 16 show an example in perspective view of this container when the container is provided with attached sheet of foldable cardboard or of plastics as its external protective wall for reinforcing its structural strength, FIG. 15 being before and FIG. 16 being after folding.
  • FIG. 17 shows a sectional view of an example of this container wherein a small size motor of a tape recorder is contained in suspension within the sustaining walls of cavities that are larger in some part than the exact contour of the article.
  • FIG. 18 is a cross-sectional view of a container similar to FIG. 17, and illustrating that the projections are wall, when joined, with a vacancy or empty space sometimes in some part of it.
  • FIGS. 19 and 20 show in cross-sectional view other examples wherein a variation in the form of projections is shown.
  • FIG. 21 shows in cross-sectional view an example of double suspension concept of this container.
  • FIGS. 22 and 23 show respectively a vertical and horizontal view of another example of double suspension concept in sectron.
  • FIG. 24 shows an unfolded view of an example of this container adapted to receive a round object like a glass ball, which illustrates that, instead of forming two side walls vertically in four triangular forms, it is possible to form them in two pyramid forms. In such case the commodity to be contained is to be supported by means of six separate walls of cavities on each top of pyramid form of projections.
  • FIG. 25 shows a side view of FIG. 24.
  • FIGS. 26, 27 and 28 show respectively its bottom, side and plan views.
  • the container herein given is thermoformed out of one sheet of thin gauge thermoplastic material.
  • the basic form of this container consists of four triangular projections b, c, d and e separated from one another by the linesj, k and [disposed in the same plane as a flange aalong the periphery.
  • the formed thermoplastic sheet constitutes a square shape with four triangular cavities accessible from the four outsides as seen in FIG. 2. It is not always necessary that each angle 61, 92, 93 and 94 is equal, as seen in FIG.
  • the projection is not always necessarily triangular in section, but sometimes it comes in a combination of two triangular projections q and s, and two trapezoid projections r and t to constitute, when folded, a rectangular form in section as in FIG. 4.
  • FIG. 5 shows that each of the four projections is formed recessed in part from the apex thereof so that, when folded, these four recessed projections joined to form the contour ofa glass cup X ofcircular or round shape as seen in FIG. 6 to support the cup X in suspension by means of the walls 2,3, 4, 5, 8 and 9.
  • ribs 6 and 7 can be added to the plain recessed parts as well as at the bottom of cavities with the aim to reinforce the dimensional strength of the container, since this is readily within the scope of those skilled in the art. It may be important, however, to say that any freely chosen commodity can be contained within this container, since it is easy to form four cavities on the top of four separate projections without encountering any undercut angle problem by dividing the contour of any given object into four parts.
  • the invention herein provides a new technique of forming any shape of contour ofa given object by dividing the contour into three, usually four and sometimes more parts, and at the same time permitting these subdivided parts to be joined again after forming the same from one sheet of thermoplastics.
  • the container of this invention can pack multiple articles at one time as seen in FIGS. ll, 12 and 13, wherein an example shows six glass cups of conical side wall to be packed in one container.
  • a sheet of cardboard or of plastic sheet can be attached to one end of the formed part of this container so that the cardboard or plastic sheet can be folded over the body of the formed part of this container, having been folded up itself to construct the external structure of this container to reinforce the dimensional strength.
  • the plastic sheet can be used, it is needless to explain, if the extension or continuation of the original sheet is left unformed, instead of another sheet being attached later.
  • thermoplastics sheet to be used for forming The qualities of the packaging structure are enhanced by the characteristics of the thermoplastics sheet to be used for forming. These characteristics comprise a thermoplastics composition which has high impact strength with synthetic rubber in its ingredients; will not soften or deform at temperature in the tropic climate; will not crack easily at far below 0 centigrade; will retain resiliency after the time interval of at least 2 years from the time of production.
  • plastic materi als usually comprise butadiene.
  • a polyvinyl chloride compound may be recommended comprising butadiene and very little or not part ofa plasticizer for the sheeting to be used for the container herein described.
  • the packaging container above described is made conventionally by resorting to vacuum forming, pressure forming or by vacuum and pressure forming techniques. But it may be mentioned that blow-molding may also be used instead of the other mentioned sheet forming methods to get this type of packaging container with minor variation in the form of the container. In this case four separate pieces can be blowmolded for subsequent joining to support an article in a loop of cardboard or of plastics.
  • a packaging container of the suspension type in which an article or articles of predetermined three dimensional shape are held in suspension comprising a sheet of plastic material adapted to be thermoformed with at least three projections thermoformed from and extending out of said sheet on the same side thereof thereby forming in said sheet a number of cavities each having four wall portions, the number of cavities corresponding to the number of projections, recess means in the apex portions of said projections providing a suspensiontype accommodation of predetermined shape for the article within said container, when folded along lines generally extending in a longitudinal direction within the area of connection between adjacent projections, said recess means generally extending in a direction opposite to that of the projections and providing double-walled end portions protecting the article in the longitudinal direction, and external cover means externally covering the cavities and secured to said sheet.
  • each projection includes two angularly disposed wall portions interconnected at their end opposite said sheet and two reinforcing end wall portions disposed substantially perpendicularly to said longitudinal direction and closing a respective cavity at both ends thereof.
  • a packaging container according to claim 2 wherein the sum of the angles formed by the intersection of each two angularly disposed wall portions is approximately equal to 360.
  • a packaging container according to claim 4, wherein said angularly disposed wall portions are substantially flat with mutually facing angularly disposed wall portions of adjacent projections abutting against each other in the folded condition of the container.
  • each recess means is spaced a distance from the corresponding end wall portions.
  • each cavity has more than four walls.
  • a packaging container thermoformed from a sheet of thermoplastic material to package an article or articles held therein in suspension comprising at least three projections, each projection including at least two angularly disposed wall portions whose length determines the height of the package and two end wall portions, the angularly disposed wall portions extending toward one another from a base plane and the two end wall portions extending reinforcingly across the outer ends of said angularly disposed wall portions to form therewith a cavity, at least some of said projections being recessed within the area of the interconnection of two angularly disposed wall portions in accordance with the requirement of the article to be suspended and each recess terminating with a recessed end wall portion formed thereby a predetermined distance from the corresponding end wall portion so that a double-walled end wall structure is formed thereby, all but one projection being attached to the next projection along a line in the respective base plane constituting also the fold line between adjacent projections, each end wall portion being adjoined substantially within the base plane by a flange portion, and
  • a packaging container thermoformed from a single sheet of thermoplastic material to package an article or articles held therein in suspension comprising four projections, each projecting including at least two angularly disposed wall portions whose lengthdetermines the height of the package and two end wall portions, the angularly disposed wall portions extending toward one another from a base plane and being interconnected at the ends opposite said base plane and the two end wall portions extending reinforcingly across the outer ends of said angularly disposed wall portions at substantially right angle to form therewith a cavity, all of said projections being recessed within the area of the interconnections of two angularly disposed wall portions in accordance with the requirements of the article to be suspended and each recess terminating with a recessed end wall portion formed thereby a predetermined distance from the corresponding end wall portion so that a double-walled end wall structure is formed thereby, all but one projection being attached to the next pro- 10 jection along a line in the respective base plane constituting also the fold line between adjacent projections, each end wall
