Assembled cup structure

Abstract

An assembled cup structure includes an outer cup body and an inner cup body disposed inside the outer cup body. The outer cup body is formed with a first curved portion on an inner wall thereof close to an outer cup mouth and a first mating portion beneath the first curved portion. An end edge of an inner cup mouth of the inner cup body is formed with a contact portion. The contact portion holds against the first curved portion. The inner cup body is formed with a second mating portion on an outer wall thereof beneath the contact portion. The second mating portion is attached to the first mating portion closely. The beverage filled in the inner cup body won't flow to the space between the two cup bodies when it is spilt.

1 . An assembled cup structure, comprising an outer cup body and an inner cup body disposed inside the outer cup body; the outer cup body being formed with an outwardly inclined curved surface disposed in an outer cup mouth thereof, a first curved portion on an inner wall thereof close to the outer cup mouth and, a first mating portion beneath the first curved portion; an end edge outwardly elongated from an inner cup mouth of the inner cup body being formed with a contact portion, the contact portion holding against the first curved portion, the inner cup body being formed with a second mating portion on an outer wall thereof beneath the contact portion, the second mating portion being attached to the first mating portion closely,
 wherein the first curved portion is an annular groove, and the inner cup body is retained in the outer cup body through the annular groove to engage with the contact portion.   
     
     
         2 . The assembled cup structure as claimed in  claim 1 , wherein the first mating portion and the second mating portion are bevels having a same slope. 
     
     
         3 . The assembled cup structure as claimed in  claim 2 , wherein the first mating portion and the second mating portion have a mating length of 1 mm to 4 mm. 
     
     
         4 . The assembled cup structure as claimed in  claim 1 , wherein the outer cup body is formed with a second curved portion beneath the first mating portion, the inner cup body is formed with a buckle portion beneath the second mating portion, and the buckle portion leans against the second curved portion. 
     
     
         5 . The assembled cup structure as claimed in  claim 4 , wherein a distance from a position where the first curved portion and the contact portion contact with each other to another position wherein the buckle portion and the second curved portion engage with each other is less than 10 mm. 
     
     
         6 . The assembled cup structure as claimed in  claim 1 , wherein a distance from a position where the first curved portion and the contact portion contact with each other to the outer cup mouth of the outer cup body is 11 mm to 16 mm. 
     
     
         7 . The assembled cup structure as claimed in  claim 1 , wherein a bottom of the outer cup body is formed with an aperture. 
     
     
         8 . (canceled) 
     
     
         9 . The assembled cup structure as claimed in  claim 1 , wherein the first curved portion is a stepped configuration. 
     
     
         10 . The assembled cup structure as claimed in  claim 9 , wherein the stepped configuration includes a stepped surface which is concave or flat, and the contact surface is held on the stepped surface.
