Having Defined Means To Limit Extent Of Nesting Patents (Class 206/519)
  • Patent number: 4542029
    Abstract: A container body made of thermoplastic materials, after being filled with a hot liquid, is then sealed by a flat closure disc adhesively contacting a peripheral lip formed around the top of the body. The bottom of the container body is formed with annular grooves to define a diaphragm which flexes inwardly with the closure disc upon cooling of the hot filled liquid to substantially dissipate the high internal vacuum which is formed in the container head space. The bottom of the container body has a reinforced pedestal base formed with stacking ledges to facilitate nesting of empty bodies for shipment and storage.

  • Patent number: 4529092
    Abstract: A container for door panels or other articles includes a sling divider having transverse support rods equally spaced along a flexible web. The ends of the rods are received in vertically staggered pairs of side wall pockets so that web sections form slings of different depths relative to the top of the container and thus allow the laterally projecting portions of the articles to deform the web and overlap to accommodate more articles in a container of given length. In the preferred embodiment, the container is rectangular with longer side and shorter end walls, and is nestable with nesting stops that establish a nesting space between the bottom walls of two nested containers, and the support rods are long enough to extend between the side walls but are shorter than the distance between the end walls so the sling divider can be removed, turned, and stored in the nesting space.

  • Patent number: 4368818
    Abstract: A stackable thin-walled cup is designed to absorb telescoping loads with less risk of jamming and is for use in beverage dispensing machines with an ingredient held in the cup. As shown in FIG. 2 an ingredient is retained in the base 11 of the cup 1 which has an inward projecting annulus 6 with upper and lower surfaces 8 and 7 arranged to cooperate with surfaces 4 and 5 of an outwardly projecting annulus at the base of a second stacked cup. Surfaces 4 and 7 form a seal to prevent loss of ingredient and the two surfaces are held in contact by a force due to abutment between surfaces, 9 and 10 of respective cups. By suitable difference in linear dimension between surface 7 and abutment 10 and surface 4 and abutment 9 a force is produced by tension derived from the cup walls to hold the surfaces 4 and 7 together. Telescopic shock loads produce compression on the abutments 9 and 10 and momentarily separate surfaces 4 and 7 which re-engage on removal of the load.

    Abstract: Food storage vessels in the form of foam polystyrene cups are each formed with an enlarged cap seat extending from a bottom wall of the cup to define a compartment to be filled when the cups are inverted, with deliquescent or hygroscopic material which can be reconstituted with the addition of water. The cups are inverted after stacking and held together by means applying endwise pressure thereto. In this nested and stacked condition, each cup has a depending base wall, which forms the cap seat, in sealed engagement with an adjacent portion of an adjacent nested cup to provide a sealed enclosure for the material between adjacent cups. Each of the cups is a thick wall, one-piece molded plastic cup preferably of foamed polystyrene.

  • Patent number: 4146170
    Abstract: A rectangular container cover includes sidewalls having an intermediate, horizontally extending ledge and downwardly depending end segment shaped to fit over a peripheral rim of a container such that the horizontal ledge is in abutment with the container lip. The cover is made of a flexible material with detents provided for releasably attaching the cover to a container near each of the corners. The corners of the cover have a radius of curvature greater than the radius of curvature of the container on which the cover is adapted to fit such that when positioned on the container, the sides of the cover are in tension and snugly fit against the associated container.

  • Patent number: 4111303
    Abstract: A nestable container of resilient plastics material comprises integral bottom and side walls, the side walls diverging generally from the bottom to the top. The container has means for holding the containers together in a stack, comprising projections which provide pairs of mutually opposed shoulders on the outside of the container and projections on the inside of the container. The space between the shoulders of each pair is slightly less than the width of each projection on the inside of the container so that when such identical containers are brought together the shoulders on one container are displaced circumferentially to allow the projections on the inside of the other container to pass between them and engage behind them holding the cups together.

  • Patent number: 4096947
    Abstract: A synthetic resinous nesting cup construction suitable for manual or mechanical or serial dispensing. The cups, in nested condition, each define a recess capable of retaining a dehydrated commestible above a lower wall thereof, the recess being sealed by the engagement of each cup with another nested therein over a predetermined peripheral area adjacent the upper edge of the cup, whereby a substantially uniform force along the axis of a stack of cups is required for each successive separation. The cups are substantially free of other contact when nested. In alternate forms of the invention, the recess is sealed by a soluble or frangible wafer, permitting the cup to be stacked in upside down condition for manual or mechanical separation from a console of table height.
