Patent number: 4368818Abstract: 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.Type: GrantFiled: April 13, 1981Date of Patent: January 18, 1983Assignee: Mono Containers (U.K.) LimitedInventors: Robert H.

Patent number: 4111303Abstract: 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.Type: GrantFiled: July 29, 1976Date of Patent: September 5, 1978Assignee: Mars LimitedInventor: Peter Arnold Compton

Patent number: 4096947Abstract: 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.Type: GrantFiled: January 21, 1977Date of Patent: June 27, 1978Inventor: Milton Morse
