Definitions

  • This invention relates to a shock absorbing storage and shipping container. More specifically, it relates to containers for shipping fragile or other products which must be delicately handled.
  • the instant invention utilizes two hollow integral shells which may be joined by a hinge design which mate with one another and close about an article.
  • Each of the shells are made of a polymeric material which preferably has a high tensile and impact strength.
  • the shells may have a box shape appearance with external walls preferably of a thickness of less than 25 mils. At least one surface of each of the shells is modified so as to permit sealing engagement with the other shell, and define an article containing space for enclosing an article.
  • each shell contains a foamed polymer therein to provide a sufficient shock-proof characteristic and to inherently form a lock and/or between the two shells so as to provide a closed container.
  • Another object is to provide a shock-proof container which is fire suppressing, puncture-proof, and extremely resistant to stress cracks, but yet economical and efficient to manufacture in mass volume.
  • the container is designed to conform its article containing cavity to the configuration of the article so as to firmly encapsulate the article and preclude its movement within the container. Too, it is an object to provide a container in which the position of the article therein is specifically defined and spaced from the seal and external surface of the container so as to enhance the containers sealing and protection characteristics. Finally, it is an object of the instant invention to provide a process for making such containers.
  • FIG. 1 is a perspective view of the exterior of a preferred embodiment
  • FIG. 2 is an exploded view in perspective of the two halves of this embodiment
  • FIG. 3 is a side elevational view of this embodiment taken in section along the lines 3-3 of FIG. 1.
  • FIG. 4 is a perspective view of the locking and sealing mechanism for the instant embodiment
  • FIG. 5 is an exploded perspective view ofa mold uti lized in making this embodiment
  • FIG. 6 is an elevational view taken in section along the lines 6-6 of FIG. 5 of the upper portion of the mold
  • FIG. 7 is a symbolic view of one apparatus and method of forming the shell of this embodiment within the mold of FIG. 5;
  • FIG. 8 is an exploded perspective view of the two shells of this embodiment prior to closing
  • FIG. 9 is a side elevational view in section of the lower shell of the embodiment taken along the lines 99 of FIG. 8;
  • FIG. 10 is a side elevational view in section of a complete container taken along the lines l0l0 of FIG. 3;
  • FIG. 11 is an elevational view in section of another embodiment of the instant invention.
  • FIG. 12 is an elevational view in section of a third embodiment of the instant invention.
  • FIG. 13 is a perspective view of the embodiment of FIG. 12 prior to the closing of the container.
  • the instant invention utilizes two shells of a polymeric material which will produce the desired characteristics of high tensile strength and toughness.
  • the two shells so formed are adapted to mate with one another about the fragile article which is to be shipped.
  • the container is completed by placing an expandable liquified foam in the interior of each of the shells which provides, upon expanding, a shockabsorbing, rigid cellular character to the package. Additionally, this liquified foam upon expanding will provide a self-locking characteristic.
  • FIG. 1 represents a container formed of upper and lower shells 12 and 14 which have been joined or locked together by in-situ plastic foam molding as hereinafter explained.
  • Each of the mold shells may take the form of a hollow rectangular box having four sides 16, an exposed surface 18 which may be either the top or bottom of the container, and a mating surface 20.
  • This mating surface may be formed so as to define a first flat surface 21 extending around the periphery of an article containing space, a sealing channel 24 of semi-circular configuration and a second flat surface 25.
  • Appropriately located on the surface 25 are article containing spaces 22 which have a general configuration of the article to be contained.
  • these spaces 22 are semi-cylindrical in shape, and define article containing cavities 26 when the upper and lower shells l2 and 14 are joined together at the mating surfaces 20.
  • the semicircular sealing channel 24 which circumscribes the cavaties 26 will define a circular channel around this space upon mating of the two shells.
  • apertures 30 are formed, preferably, within the channel 24, so as to permit the interior of each of the shells 12 and 14 to communicate with one another.
  • the foam 40 As the foam 40 expands through the apertures 30 and solidifies, it will integrally lock the two shells together about the article within cavity 26 so as to form a self-locking, tamper-proof, self-sealing closure means 44 which is appropriately depicted in FIG. 4.
  • expanding foam 40 will completely fill the sealing channel 24 so as to form a cylindrical sealing means 46 extending about the enclosed articles, with extensions 47 extending inwardly into each of the other shells and forming a solid lock.
  • the apertures 30 in one shell may be reduced in number or offset with respect to the apertures in the shell to which the seal is to remain attached. Additionally, if the material forming the shell has a reduced thickness or flexibility in the cavity defining areas the expansion of the foam will cause the cavity to conform to the article therein.
  • the exterior shell is formed of a polymeric material which has a high tensile and impact strength, which is relatively rigid and resistant to punctures.
  • Suitable materials for forming such a shell would include such polymers as polybutylene terrepthalate which is marketed under the trademark VALOX by General Electric Company, Inc. and having a sales office at One Plastics Avenue, Pittsfield, Mass. or any fluorohalocarbon material such as TEFLON. These materials are most appropriate when a fire-resistant container is desired.
  • Other polymers which provide desirable exterior packaging characteristics may be found acceptable.
  • polyethylene, polyurethane or polycarbonate polymers may be utilized if desired.
  • polyethylene or polyurethane foams are generally employed, but any plastic which is capable of forming a cellular structure and provides the desired rigidity for the container is acceptable.
  • FIGS. 5 through 10 A preferred method of manufacturing such a container is depicted in FIGS. 5 through 10.
  • the hollow shells 12 and 14 are preferably formed through a rotational molding process.
  • a plastic charge of the polymer material which forms the shell is placed inside a hollow mold 50 which is then rotated about two axes at predetermined speed ratios within an oven so as to subject the mold and the polymeric material to heat.
  • the powder contacting the heated metal surfaces will melt to form a film thereon which solidifies through a subsequent cooling process.
  • a suitable mold for each of the shells is identified by the numeral 50 and includes an upper mold half 52 and a lower mold half 60.
  • the lower mold half is merely a rectangular metal box taking the general configuration of the external portion of the shell, and has four sides 62 and a bottom 61.
  • the polymer material Prior to the rotational molding process, the polymer material is placed within the lower half 60 with the upper half 52 being placed thereon.
  • the upper mold half is designed as a flat plate 53 with core forming elements 54 extending downwardly to define the article containing spaces 22 within the finished container. As indicated, the elements 54 are of a substantially thicker cross-section than the remainder of the upper mold half for purposes hereinafter described.
  • a core forming element 56 having a general semi-circular configuration extends around the periphery of plate 53 so as to form the sealing channel 24.
  • plugs 57 of a thermally non-conducting material extend through the plate and the core forming elements 56 at selected points for purposes hereinafter described.
  • the upper mold half has an interior surface contoured so as to define a shell having the configuration identified in FIGS. 1 through 4. If desired, one mold might be utilized to make both shells with a hinge interconnecting them.
  • the polymeric material is placed within the lower mold half 60 with the upper mold being closed thereon. Subsequently, this mold and the material therein is clamped to a rotational molding unit identified symbolically in FIG. 7.
  • This rotational molding element is designed to rotate the mold within a heating unit about two different axes so as to insure a relatively uniform distribution of polymer material about the interior of the mold.
  • a primary drive shaft 72 suitably journalled within an appropriate supporting means (not shown) is rotatably driven by an electric motor or other means 74 so as to rotate a yoke 76 about the axis of this primary shaft.
  • a means of carrying the mold may include two shafts 78 suitably journalled within the yoke so as to permit rotational motion of the mold in a second direction which is generally perpendicular to the axis of the primary drive shaft 72.
  • the primary drive shaft 72 is provided with an extension 79 carrying a gear 81 for driving a chain 82.
  • This chain is then coupled with a second gear 84 on a secondary drive shaft 85 which is rotationally supported by an appropriate means (not shown).
  • a bevel gear 89 which meshes with the drives a pinion gear 90 constrained for rotation with the shaft 78.
  • this apparatus is capable of rotating the mold in at least two directions of varying speeds so as to cause the polymer material in contact with the metal to melt about the mold forming a completed shell 12 or 14.
  • the phenolic plugs do not conduct heat, powder falling on them will not melt and apertures 30 in the sealing channel 24 will result.
  • these apertures may be formed after molding by boring operations.
  • the mold 50 is then permitted to cool thus solidifying the shell such that it may be removed.
  • a liquified polymer foam is injected into the apertures 30 of each of the shells 12 and 14 by any conventional in-situ foaming process.
  • the liquid foam is to be injected by nozzles 105 of a conventional foam console-ejector gun through the apertures 30 into the shells.
  • other apertures might be provided for the injection process.
  • the top shell 12 is placed overthe lower shell 14 to encase the fragile article 100 at which time the two shells may be placed in a compression chamber (not shown) during the expansion and solidification of the foam such that they will maintain their shape.
  • the shells may adequately support themselves without distortionduring such expansion.
  • the liquified foam expands and solidifies within each of the shells, such will fill the upper and lower shells 12 and 14 and pass through the apertures 30 so as to provide an integral connection between the foam within two shells to lock them together about the article 100, such locking effect resulting from the mechanical interlocking of the foam and from the adhesive character of the foam adhering to the surfaces of the sealing channel.
  • the core members 54 of the upper mold section 52 has a much thicker metallic cross section than the remainder of the upper mold section. This increased cross section results in less heat transfer to the interior surface of the mold adjacent the spaces 22. Thus, less material will melt on these surfaces and accordingly, the shell thickness adjacent the article to be enclosed will be much thinner in crosssection and less rigid.
  • the purpose of this flexibility is explained with reference to FIGS. 9 and 10.
  • the expanding foam will act with sufficient force against these thinned areas of the article defining cavity 22 so as to cause same to move upwardly and rigidly encapsulate the article 100 so as to preclude any movement thereof.
  • FIG. 11 depicts another modification of my invention which includes a bottom shell 14 similar to that previously described.
  • a different closure 104 is illustrated.
  • This closure may take the form of a flat sheet of plastic material, wood, or container board which is provided with a peripheral sealing groove 105.
  • the foam 40 is injected into the bottom shell 14 and expands into the annular sealing channel 24.
  • the seal and lock between the top 104 and the shell 14 is one of adhesion.
  • the surfaces of the channels 105 and 24 may be provided with different textures so as to vary the strength of the adhesive lock.
  • FIGS. 12 and 13 illustrate another embodiment of my invention, and comprises two shells similar to that of the embodiment of FIGS. 1-4.
  • the apertures 30 are omitted with the foam being inserted through other openings (not shown).
  • another shot of foam may be injected through an aperture 111 formed through on or both sealing surfaces 21.
  • the foam in-place feature of my invention relates to the sealing and adhesive locking characteristics of the foam.
  • An improved container comprising two hollow shells each constructed of one-piece polymeric material, a surface of one shell mating with a surface of the remaining shell, said mating surfaces defining therebetween a container interlocking as well as parting area, said surfaces having apertures therein for permitting communication between the shells, an article containing space between said surfaces, and cellular plastic material filling each of said shells and interlocking said shells together across said area through said apertures to protectively encapsulate an article within said article containing space while permitting said shells to be parted across said parting area for the removal of an article from said article containing space.
  • both said surfaces include channel means circumscribing said article containing space, and said apertures are in communication with said channel means.
