Moulded paper pulp receptacle

Abstract

A receptacle ( 10 ) of moulded paper pulp has a flat circular base wall ( 12 ) and a side wall ( 14 ) of an inverted frustoconical shape extending upwardly from the base wall to define a receiving volume. The upper edge of the side wall defines the periphery of an opening located above the base wall and has an outwardly projecting peripheral lip ( 22, 24 ) having at least two recessed portions ( 26, 28 ). The two recessed portions ( 26, 28 ) form first and second spaced-apart outwardly projecting lip portions ( 22, 24 ) which form convenient handles for the receptacle. In addition, the side wall ( 48 ) is provided with a stiffening or reinforcing shoulder ( 18 ) adjacent to its upper edge.

         42 . The receptacle as claimed in  claim 39 , wherein the recessed portions are substantially identical. 
     
     
         43 . The receptacle as claimed in  claim 39 , further comprising:
 a stiffening or reinforcing shoulder adjacent to the upper edge of the side wall.   
     
     
         44 . The receptacle as claimed in  claim 43 , wherein the stiffening or reinforcing shoulder extends around substantially the whole of the side wall. 
     
     
         45 . The receptacle as claimed in  claim 39 , wherein the width of the outwardly projecting peripheral lip between two recessed portions is non-constant. 
     
     
         46 . The receptacle as claimed in  claim 45 , wherein the width of the outwardly-projecting lip portion is a minimum at a point adjacent to the two recessed portions and a maximum between the two recessed portions. 
     
     
         47 . The receptacle as claimed in  claim 46 , wherein the width of the outwardly projecting peripheral lip portion is at a maximum at a point substantially mid-way between the two recessed portions. 
     
     
         48 . The receptacle as claimed in  claim 45 , wherein the width of the outwardly projecting peripheral lip portion varies smoothly. 
     
     
         49 . The receptacle as claimed in  claim 45 , wherein the periphery of the outwardly projecting peripheral lip lies on a locus which is substantially oval or elliptical. 
     
     
         50 . The receptacle as claimed in  claim 49 , wherein the upper edge of the side wall is generally circular and the periphery of the oval or elliptical locus upon which the outwardly-projecting lip lies is centred on the centre of the base wall. 
     
     
         51 . The receptacle as claimed in  claim 45 , wherein the outwardly-projecting lip portion is formed into first and second spaced-apart outwardly-projecting lip portions. 
     
     
         52 . The receptacle as claimed in  claim 51 , wherein the first and second spaced-apart outwardly projecting lip portions are substantially identical. 
     
     
         53 . The receptacle as claimed in  claim 39 , wherein the outwardly projecting lip portion is overturned. 
     
     
         54 . The receptacle as claimed in  claim 39 , wherein the base wall is substantially circular. 
     
     
         55 . The receptacle as claimed in  claim 39 , wherein the side wall flares upwardly and outwardly with respect to the base wall. 
     
     
         56 . The receptacle as claimed in  claim 55 , wherein the side wall has an inverted frusto-conical shape. 
     
     
         57 . The receptacle as claimed in  claim 39 , wherein the side wall further comprises a plurality of integrally-formed markings adapted to indicate the depth of liquid above the base wall. 
     
     
         58 . The receptacle as claimed in  claim 57 , wherein the integrally-formed markings form a graduated scale. 
     
     
         59 . The receptacle as claimed in  claim 57 , wherein the markings are recessed when viewed from the interior of the receptacle. 
     
     
         60 . The receptacle as claimed in  claim 39 , comprising moulded paper pulp. 
     
     
         61 . The receptacle as claimed in  claim 39 , comprising a bowl. 
     
     
         62 . A receptacle, comprising:
 a flat or substantially flat base wall; and   a side wall extending upwardly from the base wall to define a receiving volume, the upper edge of the side wall being formed into first and second spaced-apart outwardly projecting lip portions.   
     
     
         63 . The receptacle, comprising:
 a flat or substantially flat base wall; and   a side wall extending upwardly from the base wall to define a receiving volume, the upper edge of the side wall defining the periphery of an opening located above the base wall and the side wall further comprising a stiffening or reinforcing shoulder adjacent to its upper edge.
