Definitions

  • the cups are nested in a large stack and contained within a dispensing tube which is operable by a suitable mechanism to dispense each cup upon the receipt of the proper amount of money. If however, one of thegcups should not separate from the nested stack, orshould become jammed within the passageway leading to the beverage lilling station, then the purchaser is unable to receive the consideration yfor his coin. Furthermore, this vending machine is unsuitable for operation until av repairman has had the opportunity to remove the lodged c up or lcorrect any other malfunction with regard to the dispensing of the cups, Not only does such a malfunction lead to a loss of profits, but the good will lost from irate customers materially reduces the future sales in that particular vending machine.

  • the present invention -relates to nestable plastic containers of the so-called throwvaway or disposable type, which have partially foamed outer sur.- faces.
  • the containers of the presentinvention vgenerally comprise a conically shaped skirt portion or side wallsection which merges at its upper end intoa series of novel stacking rings and at its lower end into a 'double conical base.
  • the containers are generally formed of polyethylene, polystyrene, polybutadiene or modified polystyrene. A portion of their outer surfaces are expanded or foamed in accordance with the procedure set forth in copending application Ser. No. 272,540, liledvApr. 12, 1963, now Patent No. 3,262,625 issued Iuly 26, 1966. c
  • the containers which form the subject matter of this invention are so designed, that ⁇ the foamed surfaces thereof do not comein .contact with the dispensing tube in conventional vending machines, and moreover, the foamed surface of one container will not come in contact with the interior wall of a similar container in which it is nested.
  • A designates a cup of the so-called disposable type and which has been preferably molded in a unitary structure of modified polystyrene.
  • the particular compositions used in the formulation of the thermoplastic material from which the container A is formed, are more fully described in the aforementioned copending application.
  • the container A is nonjamming when in nested positions, and is of the so-called thin-walled type, and is moreover formed of integral construction.
  • the container A generally comprises an upwardly and outwardly tapering side wall S having a socalled skirt portion 1 with an overall maximum wall thickness of approximately 0.01() inch.
  • the side wall 1 tapers outwardly at an angle with respect to the vertical centerline of the container A of 7 degrees 50 minutes.
  • the minimum angle of taper of the side wall 1 is critical and is never less than 7 ⁇ degrees 50 minutes.
  • the side wall 1 integrally merges into a so-called double-conical base 2 which consists of an outer base ring 3 extending inwardly and upwardly at a dihedral angle of approximately 11.5 degrees.
  • the base 2 also includes an inner base ring 4 which integrally merges into the outer base ring 3 and tapers upwardly and inwardly at an angle of approximately 13.5 degrees displaced from the horizontal or from a plane passing through the base of the container A.
  • the overall base has an outer diameter of approximately 1.798 inches, and at the geometric center thereof, the base is set inwardly from a plane passing along the peripheral margin of the base by approximately 0.187 inch.
  • each of the portions of which taper inwardly and upwardly at a different angle, and as a result thereof a much stronger base is obta-ined.
  • a hot beverage contained within the cup would tend to weaken the base until it would bow somewhat downwardly of the skirt portion and moreover, cause a stretching of the plastic material to a point where slight contact with a relatively sharp surface would rupture the surface of the base. This problem has been eliminated by the double-conicaly shaped base described herein.
  • the skirt portion 1 of the side wall S has an overall length of approximately 2.816l inches and at its upper end integrally merges into an outwardly flaring arcuately shaped supporting shoulder 5 and which has an overall radius of ⁇ 0.040 inch.
  • the innermost edge of the supporting shoulder 5 is displaced from the axial cen.- terline of the cup A by a' distance of 1.278 inches and the outermost margin of the supporting shoulder 5 is displaced from the axial centerline of the cup A by a distance of 1.313 inches.
  • the upper edge of the supporting shoulder 5 integrally -merges into an upwardly and inwardly tapering spacing skirt 6 which extends upwardly from the upper margin of the skirt portion 1 for a distance of 0.240 inch.
  • the spacing skirt 6 tapers inwardly at an angle of approximately 7 degrees with respect to the axial centerline of the container A so that the upper margin thereof is spaced from the axial centerline of the cup A by a distance of approximately 1.297 inches.
  • the spacing skirt 6 is integrally formed with an upwardly and outwardly curving stacking shoulder 7 along its upper margin, the arcuate shape of which is formed by a radius of 0.040 inch.
  • FIGURE 3 it can be seen that the point of integral adjoinment of the stacking shoulder 7 and the spacing skirt 6 forms an annular stacking edge 8.
  • the stacking shoulder 7 integrally merges at its upper end into an upwardly extending and outwardly tapering upper side wall 9 which tapers at an angle of 7 degrees with respect to the axial centerline of the container A.
  • the upper wall 9 is integrally formed with an outwardly flaring rim 10 consisting of an upper rim-forming wall 11 which merges into a reversely bent flange 12., thereby de iining an outer rim 4margin 13, substantially as shown in FGURES 2 and 3.
  • the vertical distance between the lower margin of the stacking shoulder 7 and the upper margin of the upper rim-forming wall 11 is approximately 0.200 inch and the outer margin 13 of the rim 10 is displaced from the axial centerline of the container A by a distance of approximately 1.456 inches.
  • the container A after being formed in a suitable molding operation such as by the process described in U.S. Letters Patent No. 2,967,328 is foamed on a por tion of the side wall S in accordance with the method described in copending application Ser. No. 272,540, tiled Apr. 12, 1963 now Patent No. 3,262,625, issued July 26, 1966i.
  • the container A is suitably masked in those areas in which it is not desired to produce a foamed surface and is then steeped by immersing the container A into a suitable solvent such as trichlorofluoromethane for a period of approximately ten seconds.
  • the container A is withdrawn from this solvent, retained for an interval in dry room conditions, and then subsequently immersedinto a hot water .bath or subjected to a hot air stream for a predetermined period of time.
  • This procedure results in a foamed outer surface throughout the area of solvent immersion.
  • partially foaming the surface of the container A by this method produces expansion of the plastic material by approximately one-third of its overall thickness. It has ⁇ also been found by this procedure, that the overall structural properties of the cup are not altered by this' steeping operation while the insulating properties of the cup are materially increased.
  • the side wall S of the container A is provided with an annularly extending foamed section 14 which extends to a point three-eighths of an inch above the lower margin of the container A and to a point one inch below the upper peripheral margin of the container A.
  • the foamed section 14 has an overall thickness, measured from the outer surface of Ithe skirt portion 1 extending outwardly, of 0.012 inch thereby rendering an overall side wall and foamed section thickness of 0.022 inch.
  • the containers A are readily adaptable to being nested and stacked with a series of like containers in the manner as shown in FIGURE 3.
  • the outer surface of the supporting shoulder 5 is engaged by the annular supporting margin 8 of the stacking shoulder 7.
  • the supporting edge 8 is located at a point which is spaced inwardly from the skirt portion 1 so that the foamed surface 14 of one container A never comes into contact with the interior surface of a similar container A in which it is nested.
  • This type of stacking shoulder arrangement in combination with the foamed surface 14 has been found particularly suitable for those containers, which when disposed within vending machines and similar dispensing devices, are located in a substantially upright position and where the dispensing tube does not have a great amount of curvature.
  • container B substantially as shown in FIGURES 4-6 and which is substantially similar to the previously described container A.
  • the container B is designed with a somewhat modified form of stacking shoulder arrangement for those dispensing tubes where the containers maybe shifted slightly from a purely vertical position or where the dispensing tube may contain a slight amount of curvature as is often the case in lmany d-ispensing machines.
  • the container B is also of the so-called disposable type and is preferably molded in a unitary integral structure of modified polystyrene. Again, the particular cornpositions used in the formulation of the thermoplastic material from which the container B is formed are more fully described in the aforementioned copending application.
  • the container B generally comprises an upwardly and outwardly tapering side wall k which integrally merges at its lower margin into a so-called doubleconical base 16, the latter consisting of an outer base ring 17 which extends inwardly and upwardly at anangle of approximately 11.5 degrees.
  • the base 16 also includes an inner base ring 18 which integrally merges into the outer base ring 17 and tapers upwardly and inwardly at an angle of approximately 13.5 degrees displaced from the horizontal or from a plane passing through the base of the container B.
  • the relative dimensions of the side wall 15 and the Vbase 16 are the same as the relative dimensions of the side wall 1 and the base 2 in the container A.
  • an outwardly flaring supporting shoulder 19 which is formed by an arcuately shaped convex bight portion 20, the latter also being defined by an outwardly and downwardly extending flange 21.
  • the flange 21 tapers outwardly and downwardly at an angle of approximately 45 degrees with respect to the axial centerline of thev container B.
  • the flange 21 ntegrally merges into an arcuate supporting edge 22 having an overall thickness of approximately 0.020 inch andy which integrally merges into an upwardly and inwardly' tapering intermediate wall 23.
  • the supporting edge 22 is spaced from the side wall 15 by a distance of approximately 0.12 inch and furthermore, the inter-v mediate wall 23 tapers upwardly and inwardly at an angle of approximately 8.5 degrees with respect to the axial' centerline of the container B.
  • the intermediate wall 23 is integrally formed along its upper margin with an annular outwardly extending stacking shoulder 24 consisting of an arcuately shaped inwardly projecting annular stacking edge 25 substantially as shown in FIGURE 6.
  • the stacking edge 25 is spaced slightly inwardly of the plane in which the side wall 1 lies.
  • the stacking edge 25 integrally merges into a concave arcuate bend 26 which is sized to snugly, but nevertheless removably accommodate the supporting edge 22 and the supporting shoulder 19.
  • the arcuate bend 26 ultimately merges into an up-Y wardly extending upper side wall 27 which tapers upwardly and outwardly at an angle of 7 degrees with respect to the axial centerline of the container A.
  • the upper side wall 27 is integrally formed with an outwardly flaring rim 28 consisting of an upper rim-forming wall 29 which merges into a reversely bent flange 30, thereby defining an upper rim margin 31, substantially as shown in'FIG- URES 5 and 6.
  • the outer margin 31 of the rim 28 is displaced from the axial centerline of the container B by a distance of approximately 1.456 inches, the same as in the container A.
  • the skirt portion or side wall 15 has an overall length of approximately 2.816 inches.
  • the innermost edge of the supporting shoulder19 is displaced from the axial centerline of the container A by a distance of 1.278 inches and the outermost marginfof the support ⁇ and outwardly at an angle of approximately 7 degrees50 minutes with respect to the axial centerline of the container B, so that the upper margin thereof is spaced from the axial centerline of the container B by a distance of approximately 1.297 inches.
  • FIG- URE 6 it can be seen that the upper side wall 27 is substantially parallel to the side Wall 15 but is displaced outwardly therefrom.
  • the side wall 15 of the container B is provided with an annularly extending foamed section 32 which extends to a point three eighths of an inch above the lower margin of the container B and to a point one inch below the upper peripheral margin of the container B.
  • the foamed section 32 has an overall thickness, vmeasured from the outer surface of the side wall 1,A extending outwardly, of approximately 0.012 inch, thereby rendering an overall side wall and foamed section thickness of 0.022 inch.
  • the supporting edge 22 ofone container When placed in the nested position, it can be seen that the supporting edge 22 ofone container tits snugly but nevertheless slidably within the stacking shoulder 26 of a similar container. Again, it can be seen that the supporting shoulder 19 is spaced outwardly from'the side wall 15 by a distance which is sufficient to prevent thefoamed surface 32 of one cup from engaging the interior surface of the side wall of a container in which it is nested. It can also be seen by reference to FIGURE 6, that the arcuate edge 25 of one container engages the arcuate bend-20 of a container in which it is nested. By means of the above tainer B, and hence, it is impossible for the foamed surface 32 of one container to engage the interior surface ofthe side wall of the container B in which it is nested.
