Definitions

  • This invention relates to foamed thermoplastic containers and cups capable of being nested one into the other to protect comestible stored in the containers and cups from the atmosphere.
  • an upper cup is pushed into a lower cup so that when the lug enters the groove, the entry ramp allegedly engages the upper surface of the lug and forces the bottom of the lug to seat on the ledge to seal the space between the cups.
  • the entry ramp of the groove is supposed to push against the sloped upper portion of the lug to cause the bottom of the lug to seal against the upper surface of the ledge when the lug is in the groove and seats on the ledge.
  • the difficulty with this approach is the material which the U.S. Specification 4156483 is working with.
  • the expansion of the polystyrene beads is uneven. Additionally, the fused and expanded material is subject to cracking and chipping when overly stressed.
  • polystyrene foam is to be compressed to permit entry of the lug into the groove as proposed by Day, it must not only not be compressed beyond its “memory” so that it will be able to restore to its original shape tq,fit into the groove and provide the seal, but also it must not contain sharp corners, otherwise they will break off when compressed and not seal satisfactorily.
  • the lug is smaller than the groove it is readily apparent that the lug and ledge will not seal. If the lug is larger than the groove, because of the structure of the lug, groove and sealing ledge, the lug will not enter the groove and seat on the ledge to create the seal. Because of the structural characteristics of polystyrene foam material, it is presently impossible to consistently manufacture equally sized lugs and matching grooves - however, even if possible to consistently manufacture the same size lug and groove, it is impossible to have the.same sized lug enter the same sized groove as proposed by Day without precompressing at least one of the lug, groove wall or sealing ledge.
  • an object of this invention to provide foamed thermoplastic containers and cups capable of stacking with other containers and cups and seal the space between the adjacent containers and cups, respectively, to protect comestibles or beverage concentrates at the bottom of the container or cup, and which containers and cups are also easily dispensed from a dispenser.
  • this invention provides resilient yieldable, nestable, tapered foamed thermoplastic (including expanded polystyrene) containers and cups, each container or cup, as the case may be, having an endless groove and endless lug, extending from the inside and outside surfaces of the container or cup wall, the groove penetrating the container or cup wall through either the inner or outer surface of the cup wall a predetermined distance from the bottom of the container or cup, the endless lug extending from the other surface of the cup wall for locking in the groove of a like container or cup when nested with the other container or cup, the endless lug being slightly larger in size and preferably about 10% larger (in volume) than the groove, and preferably conforming in shape to the groove, the groove comprising an entry and exit ramp, preferably at an angle of about 15 0 to the vertical, which ramp first engages the endless lug when like containers or cups are nested, and an intermediate sealing surface angled to the entry ramp, preferably oriented
  • the bottom of the lug does not seat on the ledge but is spaced therefrom to permit the radial expansion of the lug to cause the sealing of the sealing surfaces.
  • the lug is about 10% larger than the groove. If much larger, the lug will not be accommodated by the groove and provide the seal. If much smaller, the lug will not form the requisite seal with the groove.
  • the lug can be in the range 6 to 14% larger and preferably in the range 8 to 12% larger.
  • the endless lug when the groove penetrates the outside surface of the container or cup wall, the endless lug extends inwardly from the inside surface of the cup wall and is of an inner diameter at its maximum width slightly less than the diameter of the groove at its maximum penetration into the container or cup wall. Additionally, the entry and exit ramp of the groove is adjacent the bottom of the groove and that part of the groove wall extends upwardly and radially inwardly to the intermediate sealing surface of the groove and the entry ramp of the lug for engaging the entry and exit ramp of the groove is at the bottom of the lug and is preferably angled at about the same angle as the entry and exit ramp of the groove.
  • the endless lug when the groove penetrates the inside surface of the container or cup wall, the endless lug extends outwardly from the outside surface of the container or cup wall and is of an outer diameter at its maximum width slightly greater than the diameter of the groove at its maximum penetration into the container or cup wall. Additionally, the entry and exit ramp is at the top of the groove and that part of the groove extends downwardly and radially outwardly to the intermediate sealing surface, and the entry ramp of the lug for engaging the entry and exit ramp of the groove is at the top of the lug and is preferably angled at about the same angle as the entry and exit ramp of the groove.
  • each container or cup as the case may be, having an endless groove spaced from the bottom of the container or cup, extending radially outwardly from the inside wall of the container or cup, penetrating the container or cup wall, an endless lug extending around the outside surface of the container or cup respectively, at the bottom of the container or cup, the lug being slightly larger in size and preferably about 10% larger in size than the groove, and preferably conforming in shape to the groove, the groove comprising an entry and exit ramp, preferably at an angle of about 15° to the vertical, which ramp first engages the endless lug when like containers or cups are nested, and an intermediate sealing surface angled to the entry and exit ramp preferably oriented substantially vertically, the endless lug having an entry ramp to facilitate entry and exit of the lug into and from the groove, the entry ramp of the lug oriented preferably at the same angle as the entry ramp of
  • the entry ramp of the lug is at least about 10% greater in length than the entry ramp of the groove.
  • the outer side wall of the inner container or cup is spaced from the inner wall of the outer container or cup.
  • a downwardly directed ledge may be provided on the outside wall of the container or cup, adjacent the mouth of the container or cup, for rigidity and which ledge preferably seats on the mouth rim of a lower container or cup, when the containers or cups are nested and the lug locked in the groove and the sealing surfaces radially compressed to seal the space therebetween.
  • a ledge may be provided on the inside wall of the container or cup, below the groove or lug as the case may be, between the bottom of the container or cup as the case may be and the groove or lug preferably just below the lowest part of the groove or lug but not so as to interfere in any way with the lug or the formation of the compression seal between the intermediate sealing surface of the groove and sealing surface of the lug.
  • the upper container or cup is pressed into the lower container or cup with the lug being slightly compressed by the inner tapered wall of the lower container or cup until it partially restores to its configuration as it enters the groove.
  • the entry and exit ramp of the groove exerts a force on the lug (including the entry ramp of the lug) in a direction towards the bottom of the cup compressing the lug axially to provide the compression seal between the sealing surfaces.
  • the lug is larger than the groove, the lug is not totally carried in the groove and is able to radially expand as it is compressed longtitudinally of the cup length to provide the seal between the sealing surfaces.
  • the downwardly directed ledge (if employed), at the upper end of the cup or container preferably seats on the annular rim of the container or cup.
  • each cup 12 shown best in Figures 2 and 4 being made of resilient, yieldable, foamed theremoplastic polystyrene material and having a side wall 14, bottom 16, and upper flange 18 forming rim 20 defining mouth 22.
  • groove 28 Extending outwardly from the inner wall of cup 12 and spaced a predetermined distance from the bottom is endless groove 28 defined by groove wall 29 seen best in Figure 4 having radially outwardly sloped entry ramp 30, sloped at 15 0 (in the range 12° to 18°) to the vertical, and being .015 inches (.038 cms) long vertically oriented intermediate sealing surface 32, .048 inches (.122 cms) long, and radially inwardly directed lower portion 34 angled at 20 0 to the horizontal and being .014 inches (.036 cms) long.
  • endless lug 36 At the base of cup 12 forming an endless protuberance or lug extending from side wall 14 at the juncture with the bottom 16 is endless lug 36, having an upper entry ramp 38 being .017 inches (.043 cms) (.0002 inches (.005 cms) longer than entry ramp 30 of groove wall 29) and angled at the same angle as ramp 30, sealing surface 40 angled at the same angle as surface 32 and of the same length, and ramp 42, .015 inches (.038 cms) long angled in the same manner as portion 34 of groove wall 29. Therefore, as can be seen from the dimensions of lug 36 and groove 28, lug 36 is about 10% larger than groove 28. The about 10% larger cross-sectional area of the lug can be achieved by other dimensional changes rather than increasing the length of the lug ramps.
  • the taper of the inner wall and outer wall of each cup 12 is 9° to the vertical.
  • the bottom 16 of cup 12 has transverse or horizontal portion 44 spaced from the bottom lug 36, and angled portion 46 angled 15° (in the range 12° to 18°) to the horizontal, connecting lug 36 to the horizontal portion 44.
  • Each cup 12 has outer and inner diameters at its mouth of 2.915 inches (7.404 cms) and 2.780 inches (7.061 cms) respectively and outer and inner diameters at the bottom of 1.957 inches (4.971 cms) and 1.829 inches (4.646 cms) respectively.
  • lug 36 is compressed by the inner side wall of the outer cup (see Figures 5 and 6) until the lug enters groove 28 (see Figure 6 showing the lug in its distorted configuration).
  • entry and exit ramp 30 axially compresses lug 36 longtitudinally of the cup, causing lug_36 to expand radially outwardly forcing surface 40 into intimate contact with the surface 32 for sealing the space 60 between the cups (see Figure 7).
  • ramps 34 and 42 do not touch due to the distortion of the lug, in other embodiments, they may.
  • lug 36 enters groove 38, and sealed space 60, downwardly directed ledge 26 of the upper cup seats on rim 30 of the lower cup.
  • each of the cups 12 has been modified to incorporate a horizontally extending inwardly directed ledge 62 spaced from the bottom of groove 28 (groove 28 of the same dimensions as previously indicated), ledge 62 for acting only as a scavenging ledge for supporting a scavenging disc for scavenging comestibles found above the level of the ledge after the filling cycle of the cup has been completed.
  • lug 36 (of the same dimensions as previously indicated) engage ledge 62 when lug 36 is locked in groove 28 to create a seal between surfaces 32 and 40.
  • part of cup 12 is shown having endless groove 28 1 defined by groove wall 29 1 extending inwardly from the outer surface of wall 14 adjacent bottom 16 1 , lug 36 1 extending inwardly from the inner surface of cup wall 14 1 .
  • Each of groove 28 and lug 36 1 has a shape the reverse of the shape of groove 28 and lug 36 respectively.
  • entry and exit ramp 30 1 inwardly sloped at 15 0 to the vertical corresponds to equal length entry ramp 30, intermediate vertical sealing surface 32 1 to intermediate vertical sealing surface 32 1 , and upper portion 34 angled at 20° to the horizontal corresponds to equal length lower portion 34.
  • lug 36 1 has corresponding lower equal length entry.ramp 38 1 to entry ramp 38 of Figure 4, intermediate vertical sealing surface 40 1 to sealing surface 40, and upper portion 42 1 to portion 42.
  • an upper cup 12 1 is pressed into a lower cup compressing the lug or lug 36 1 on the inner surface of the outer cup until lug 36 1 enters groove 28 1 of the inner cup.
  • entry and exit ramp 30 1 axially compresses larger lug 36 1 longtitudinally of the cup, causing lug 36 1 to expand radially inwardly and force surface 40 1 to seal with surface 32 1 for sealing the space between cups.
  • the downwardly directed ledge (ledge 26 1 ) of the upper cup seats on the rim of the lower cup when lug 36 1 enters groove 28 1 and seals the space between the nest cups.
  • the lowermost cup For discharge from the stack of cups, the lowermost cup is easily moved away from the stack and particularly the cup there- above, facilitated by entry and exit ramp 30 or 30 1 as the case may be.
