Lid assembly for cup

Abstract

A lid assembly of the present invention is used for clipping a rim flange of a cup. The lid assembly includes a lower member and an upper member. The lower member has a top clipping surface. The upper member has a bottom clipping surface. The upper member is detachably disposed on the lower member. The rim flange is clipped between the top clipping surface and the bottom clipping surface. Therefore, the lid assembly can be firmly assembled on a cup, even though the specification of the cup is slightly changed. Moreover, the lid assembly can not be detached unpredictably.

1 . A lid assembly for a cup, the lid assembly being used for clipping a rim flange of the cup, the lid assembly comprising:
 a lower member, comprising an annular clipping portion and a holding portion, the holding portion stretching from the clipping portion, the clipping portion having a top clipping surface, an outer contour of the top clipping surface being not smaller than an outer contour of the rim flange;   an upper member, comprising a bottom clipping surface, an outer contour of the bottom clipping surface being not smaller than an inner contour of the rim flange, the upper member being selectively fixed on the lower member, so that the top clipping surface and the bottom clipping surface are able to clip the rim flange therebetween.   
     
     
         2 . The lid assembly of  claim 1 , wherein the holding portion is ring shaped, the holding portion stretches downwardly from the clipping portion. 
     
     
         3 . The lid assembly of  claim 1 , wherein the upper member further comprises a lid layer, the lid layer substantially covers an opening of the cup, a hole is defined by the lid layer, the hole communicates with an inner space of the cup. 
     
     
         4 . The lid assembly of  claim 3 , wherein the bottom clipping surface is located on a bottom surface of the lid layer. 
     
     
         5 . The lid assembly of  claim 1 , wherein the upper member further comprises plurality of lower pressing protrusions, the lower pressing protrusions are disposed on the bottom clipping surface, the lower pressing protrusions are used for clamping an inner edge of the rim flange. 
     
     
         6 . The lid assembly of  claim 1 , wherein the lower member further comprises plurality of upper pressing protrusions, the upper pressing protrusions are disposed upwardly on the top clipping surface, the upper pressing protrusions are used for inserting in a slit defined between the rim flange and a cup body of the cup. 
     
     
         7 . The lid assembly of  claim 1 , wherein the clipping portion further comprises an inner side surface, the inner side surface is adapted for an outer surface of a cup body of the cup to smoothly fit therewith. 
     
     
         8 . The lid assembly of  claim 5 , wherein the clipping portion further comprises an inner side surface, the inner side surface is adapted for an outer surface of a cup body of the cup to smoothly fit therewith. 
     
     
         9 . The lid assembly of  claim 6 , wherein the clipping portion further comprises an inner side surface, the inner side surface is adapted for an outer surface of a cup body of the cup to smoothly fit therewith. 
     
     
         10 . The lid assembly of  claim 1 , wherein the lower member further comprises a threaded outer side surface, the upper member further comprises a threaded portion, the threaded portion is able to be screwed on the outer side surface. 
     
     
         11 . The lid assembly of  claim 5 , wherein the lower member further comprises a threaded outer side surface, the upper member further comprises a threaded portion, the threaded portion is able to be screwed on the outer side surface. 
     
     
         12 . The lid assembly of  claim 6 , wherein the lower member further comprises a threaded outer side surface, the upper member further comprises a threaded portion, the threaded portion is able to be screwed on the outer side surface.
