Definitions

  • the present invention relates to the stacking of a plurality of similarly configured containers of thin wall plastic construction which are of the disposable variety. Stacking in thin-walled containers of the disposable variety, where upward of 50-75 containers or more are nested together, is imperative to limit the degree of telescoping between nested containers. Failure to include a stacking configuration or the use of an unworkable stacking configuration in such containers between adjacent nested containers.
  • stacking features can be incorporated into either the side Wall or bottom wall of a thin wall plastic container of one-piece integral construction.
  • a side wall stacking technique is disclosed in my U.S. Patent No. 3,139,213 in which a stacking ring, reversely directed with respect tothe divergence of a container side wall, is provided to limit the degree of telescoping between adjacent nested containers.
  • Variations of a reversely tapered stacking ring incorporated into a thin wall plastic container are shown in my US. Patent No. 3,091,360 where the stacking ring is of the interrupted variety, and in my US. Patent No.
  • Another object of the present invention is the provision of a thin wall plastic container having stacking pleat means of double wall thickness which is designed to increase the stacking overlap between adjacent nested containers while at the same time laterally reinforcing or rigidifying the container in the vicinity of the stacking pleat means.
  • a further object of the present invention is the provision of stacking pleat means in a thin wall seamless thermoplastic container which, in certain forms of the invention, are designed to provide centering between adjacent nested containers when brought into stacking engagement, while in other forms of the invention, incorporate resilient resistance in an axial direction to prevent jamming and damage to the stack of containers.
  • a one-piece thinwalled seamless thermoplastic container having stacking pleat means formed therein which cooperate with a cir- .pumferentially extending stacking surface of the container, the majority of instances comprising a plurality of generally axially extending and circumferentially spaced stacking pleats of double wall :thickness which are formed in the vicinity of the circumferentially extending stacking surface, each of the stacking pleats being radially oifset from the container in a direction to cooperate with the circumferentially extending stacking surface of a like adjacent nested container to provide stacking therebetween, the plurality of stacking pleats capable of being located either in the side wall, the bottom wall, or traversing at least both of the bottom wall and side wall of the container.
  • the stacking pleat means is located within the interior of the container body and angularly disposed relative to the container axis to afford resiliency between adjacent

  • FIG. 13 is a fragmentary side elevational view of a pair of nested containers, one of them being sectioned, illustrating stacking pleat means formed generally in the central portion of the side walls of each of the containers;
  • FIG. 14 is a fragmentary side elevational view of a pair of nested containers, one of them being sectioned, which illustrates stacking pleat means formed in the side walls of each of the containers, and cooperating with the upper margin or rim portion of the containers for stacking.
  • thermoforming techniques wherein a heated sheet of thermoplastic material is drawn to the desired shape by mold members, mold members in combination with fluid pressure either of the positive or negative variety, or pressure forming means solely. It will, of course, be recognized that any of the above thermoforming techniques may be used in producing the various container embodiments which will now be described.
  • FIGS. 1-3 of the drawings there will be seen a one-piece, seamless, thin-walled cup or container 10 of the type referred to above.
  • the cup or container 10 is formed into a frusto-conical shape which includes a bottom wall 12 which is integrally joined at its periphery or margin to a peripherally continuous side wall 14 diverging upwardly and outwardly from the bottom wall 12 and terminating in a rim portion 16 to define the upper margin of the cup in the vicinity of the open mouth or open upper end thereof.
  • the rim portion 16 is preferably of the rolled or curled rim variety in the sense that it is reversely curved from the upper margin of the container back towards the side wall 14 to provide a rim of increased lateral width relative to the thickness of the side walls to afford necessary lateral rigidity at the open mouth or open upper end of the cup while affording a smooth drinking surface. It will, of course, be recognized that any thickened rim which provides the foregoing advantages may be used if desired.
  • the bottom wall 12 is preferably of the indented bottom variety by its being axially concave upwards so that it will prevent sagging or oil canning of the cup when filled with a liquid. As will be described in more detail hereafter, the indented bottom construction may be dispensed within certain forms of the invention by reason of the rigidity derived from the stacking facility.
  • the cup 10 is provided with stacking pleat means formed integrally into the cup body, and which cooperates with a circumferentially extending stacking surface as will become apparent hereafter to stack adjacent nested or telescoped containers apart from one another a sufficient distance to prevent jamming therebetween which creates the various heretofore noted disadvantages, thereby making the cup acceptable to consumers by reason of their becoming stuck or wedged together.
  • the stacking pleat means 18, in cooperation with the circumferentially extending stacking surface to be presently described, must space the containers apart from one another an axial direction greater than the axial height of the rim portion 16 so that there will be no interference therewith. This is a common problem which any stacking facility must overcome in order to function effectively.
  • the stacking pleat means comprises a plurality of generally axially extending and circumferentially spaced stacking pleats 20 which are formed into double wall thickness elements.
  • each of the stacking pleats have a thickness which is at least double the thickness of the substantially uniform in thickness cup 10 which will vary a few thousandths, more or less.
  • the stacking pleats 20 in the FIGS. 1-3 embodiment are generally triangular in shape and include a pair of juxtaposed, substantially parallel wall portions 22, 22 which are joined to each other at the radially innermost ends thereof by an upwardly and outwardly tapering connecting wall portion 24 which diverges from the bottom wall at a different angle than the side wall 14.
  • Each of the stacking pleats 20 traverse at least part of the bottom wall 12 and side wall 14 of the cup, and thus extends on both sides of the area of juncture therebetween.
  • the stacking pleats 20 will interfere and prevent complete telescoping movement between adjacent nested containers as is readily depicted in FIG. 3 of the drawings.
  • the stacking pleats of the lowermost cup is designed to engage the bottom margin of the uppermost cup so that there will be stacking interference between each pair of adjacent nested cups.
  • the bottom margin of the uppermost cup serves as the circumferentially extending stacking surface which cooperates with the stacking pleats 20 of the lowermost cup to positively limit telescoping movement between adjacent nested cups when such elements are brought into engagement with one another.
  • each of the stacking pleats are illustrated as having an opening 21 in the vicinity of the upper portion thereof, and it is from these openings that a tool or pin is extracted after the formation of the stacking pleats 20 as will be apparent.
  • the maximum space between the substantially parallel, juxtaposed wall portions 22, 22 of each stacking pleat should have a dimension smaller than the minimum distance or dimension of each connecting wall 24 joining the juxtaposed wall portions 22, 22. In this way, any registry or slight telescopic shifting between the pleats 20 of ad jacent nested containers will be prevented.
  • each stacking pleat taper upwardly and outwardly so that they can act to center ad acent nested cups when brought into stacking engagement.
  • the connecting walls 24 by reason of their angular disposition, will act to center adjacent containers.
  • stacking pleats 20 due to their construction will laterally rigidify the side wall in the vicinity of their location as well as part of the bottom wall of each cup. It is conveivable that certain forms of the invention may utilize the vertical rigidity of the stacking pleats 20 to strengthen the bottom wall and prevent the sagging or oil-canning above mentioned While the stacking pleats 20 of this invention depend upon vertical and lateral rigidity, and thus are distinguished from my prior patents mentioned above which employ axial resiliency in a stacking facility to absorb shock and prevent damage between containers in a nested stack, the stacking pleats 20 are designed to solve stacking problems in thin wall plastic containers by a technique which although not advantageous as the stacking facilities of my prior patents mentioned above, is quite useful and can be employed in this particular field.
  • the stacking pleats 20a have a modified shape in the sense that the connecting wall 24a between the juxtaposed wall portions 22a of each stacking pleat is subdivided into two sections, an upper section 26 which tapers upwardly and outwardly generally after the fashion of the connecting wall 24 in the FIGS. 1-3 embodiment, and a lower section 28 which is substantially vertically arranged and substantially parallel with the axis of the container.
  • the stacking facilities 18b of each of the containers 10b is modified to show a slightly curving surface for the connecting walls 24b of each stacking pleat 2012.
  • the connecting wall 240 between each pair of juxtaposed wall portions 22c of each stacking pleat is similar to the FIG. 4 embodiment in the sense that it is also subdivided into an upper and a lower section designated 26c, 28c, respectively.
  • the upper and lower sections 260, 28c of each connecting wall have a slight curvature thereto.
  • FIGS. 4, 5 and 6 embodiments will function generally in the same manner as the FIGS. 1-3 embodiment, including the centering action between adjacent nested containers. These embodiments will serve to indicate to those skilled in the art of the various modified constructions or shapes of the stacking pleats 20 which may be used in those instances where a centering action between adjacent cups in addition to the other advantages may be obtained.
  • FIG. 6A indicates an opening 21C on the bottom wall for each of the stacking pleats 20c, and this corresponds to the openings 21 in the FIGS. 1-3 embodiment. This type of construction would be typical for containers of the type illustrated in FIGS. 4 and 6.
  • the stacking pleat means 18d of the FIG. 7 embodiment comprises an inwardly directed element which extends from the juncture of the bottom wall and side wall 12d, 14d, respectively, of each cup 10d
  • the stacking pleat element 20d is similarly of at least double wall thickness which respect to the thickness of the container body 10d as in the other embodiments, but is annularly disposed in a reversely tapering or back tapered manner with respect to the taper of the side wall 14d of each container.
  • This stacking pleat element 20d which may be circumferentially continuous or interrupted at selected points as shown by the phantom lines in FIG.
  • the stacking pleat element 20d of a lower container when engaged by the bottom wall 12d of an upper container, will deflect downwardly about a point in the vicinity of the juncture of the bottom wall and side wall 12d and 14d respectively of the lower container, thus providing a degree of axial resiliency to a stack of containers. In this way, it will more nearly act as a shock absorber when a stack of containers is subjected to an axial load, such as by an inadvertent dropping of the stack.
  • the containers there illustrated incorporate a modified form of stacking pleat means 20c.
  • the connecting wall 24c between juxtaposed wall portions 22c, 22:: of each stacking pleat extends first in a substantially vertically oriented direction from the bottom wall 12:: of each container, and then at a point spaced from the bottom wall 12s of the container, proceeds in a direction substantially normal to the axis of the container.
  • This will provide a substantially horizontally directed supporting shelf 30 which cooperates with the bottom margin or circumferentially extending stacking surface of an uppermost container to positively limit telescoping between adjacent containers.
  • openings 21c are provided in the bottom wall of the containers We as shown in FIG. 8A adjacent the pleats 20a for the reasons previously given.
  • the two forms of containers shown in FIG. 9 and FIGS. 10-11 and identified 10f and 10g, respectively, differ from all previous embodiments in the sense that the stacking pleats are located entirely within the boundaries of the bottom wall of each container.
  • the substantially rectangular stacking pleats 20] in the containers 101 in FIG. 9 of the drawings are located entirely within the confines of the bottom wall, and project axially upwards therefrom.
  • the stacking pleats 20g have a semi-oblong shape, and are located entirely within the confines of the bottom 12g of each container 10g.
  • stacking pleats 20h it is also possible to form the stacking pleats solely within the side wall of each container as is shown by the stacking pleats 20h in the container 10h of the FIG. 12 embodiment. There, it will be seen that the stacking pleats 20h cooperates in the same manner with the bottom margin or circu-mferentially extending stacking surface of an upper container to limit telescopical movement adjacent nested containers.
  • the cups previously discussed refer to the circumferentially extending stacking surface as being the bottom margin of the container, it is also possible that such surface may be incorporated into the side wall or relate to the upper margin of the cups as is illustrated in FIGS. 13 and 14- of the drawings.
  • the cups 10i each are provided with a plurality of outwardly directed stacking pleats 20i in the side wall thereof which are designed to engage a circumferentially extending stacking surface 32 provided immediately above the stacking pleats 20i in each of the containers.
  • the stacking surface 32 is generally horizontally directed and is radially inwardly offset relative to the stacking pleats 20i such that the stacking pleats 20i of an uppermost container will be capable of engaging and resting upon the circumferentially extending stacking surface 32 of a lowermost container.
  • the outwardly directed stacking pleats 20 in each of the cups 10 are radially outwardly directed from the side wall 14 of each container and are positioned in close proximity to the rim 16j which defines the upper margin of each cup 10f.
