Low profile press-fit compostable beverage lid

Abstract

A disposable, single use, press-fit lid made from compostable press molded fibers for use with disposable beverage cups with or without an annular rim. The lid has a circular peripheral rim ( 11 ) with an extending edge to provide positional contact with the beverage cup rim. The circular peripheral rim ( 11 ) is connected to a primary lower platform ( 21 ) through a cup engaging wall ( 10 ). A secondary central raised platform ( 8 ) rises at an angle from the primary lower platform ( 21 ) from the lower end of the raised platform ( 19 ) distal to a drinking spout, up to the drinking spout which is at level with or slightly above the peripheral rim ( 11 c ). This central raised platform ( 8 ), includes two constrictions ( 15 ) referred to as finger holds that are positioned mid slope, diagonally from one another, between the lower end of the raised platform and the drink spout opening ( 9 ). These finger holds allow the easy manipulation of the lid during use. At least one vent ( 14 ) is positioned on the central raised platform equidistant to and adjacent to the finger holds ( 15 ). Located at the highest point of the central raised platform, in front of the finger holds ( 15 ), is the drinking spout ( 9 ). Generally rectangular in shape with rounded edges, a drinking spout proximal edge ( 17 ) extends along the width of the central raised platform at its highest point, adjacent to the outer peripheral rim ( 11 ). The proximal edge ( 17 ) curves to an angle perpendicular to itself to form a drink spout side edge ( 18 ), which further extends through the outer peripheral rim ( 11 c ) of the lid to produce an open drinking spout and a comfortable, compostable drinking experience.

1 . A single use compostable lid for a beverage cup, comprising a circular peripheral rim adjoining a near vertical cup engaging wall of substantial length, contiguous with a primary lower platform that contains within it a secondary raised central platform with the means to provide both a raised drinking hole that adjoins the peripheral rim of the lid and a finger hold structure. 
   
   
       2 . Said compostable lid of  claim 1  is composed of Bagasse and other biodegradable/compostable fibers. 
   
   
       3 . Said circular peripheral rim of  claim 1  joins said primary recessed lower platform to produce a cup engaging wall of substantial depth, means to provide a friction seal between the lid and an intended cup 
   
   
       4 . Said secondary raised central platform of  claim 1  is disposed along the mid line of the recessed lower platform, rising from the lower platform to join the peripheral rim at location of said raised drinking hole. 
   
   
       5 . The raised platform of  claim 4  is joined to said primary lower platform through a contiguous near vertical wall which is disposed with said finger hold structure composed of  2  constrictions, one on either side of the raised platform, at a point between the emergence of raised platform from the lower platform and said raised drinking hole. 
   
   
       6 . The raised platform of  claim 4  further includes a vent hole located mid line on the raised platform, adjacent to the finger holds. 
   
   
       7 . Said raised drinking hole of  claim 1  is located at the end of the raised platform at the height of the peripheral rim, effectively cut into the lid where the raised platform joins the peripheral rim.
