Drinking cup structure

Abstract

A drinking cup may include a cup body, and an inverted V-shaped partition separates the cup body from a bottom end thereof to form two symmetrical compartments at both sides of the partition, and the two compartments are connected at top portions to form a top edge which is connected to an inner edge of an opening of the cup body at both ends thereof, thereby separating the opening into two symmetrical portions. A protruding bar slightly protruding along a middle line of the top edge is configured to be melted by a heat press head of a sealing machine when sealing a sealing film on the opening of the cup body. With the two separated compartments, a customer can have two kinds of drinks by only one drinking cup, which is greener and allows the customer to have more choices.

What is claimed is: 
     
         1 . A drinking cup comprising:
 a cup body, and an inverted V-shaped partition separating the cup body from a bottom end thereof to form two symmetrical compartments at both sides of the partition, and the two compartments connected at top portions to form a top edge which is connected to an inner edge of an opening of the cup body at both ends thereof, thereby separating the opening into two symmetrical portions; each of the compartments having a cup bottom, and an outer periphery of the opening comprising a flange; a protruding bar protruding along a middle line of the top edge, and a bottom end of the partition separated to form a recessed portion, thus allowing the drinking cup stackable.   
     
     
         2 . The drinking cup of  claim 1 , wherein a top surface of the flange has an annular protruding portion which is formed along a middle line thereof. 
     
     
         3 . The drinking cup of  claim 1 , wherein a sealing machine is configured to seal a sealing film on a top portion of the cup body through a heat press head, and the heated heat press head is configured to melt the protruding bar to smooth an uneven top surface of the top edge of the partition causing by a manufacturing process of injection molding such that the sealing film is configured to firmly attach on the top edge of the partition and the flange to prevent drinks in the two compartments from spilling out or being mixed. 
     
     
         4 . The drinking cup of  claim 1 , wherein a cup lid covers on the top portion of the cup body. 
     
     
         5 . The drinking cup of  claim 4 , wherein an outer periphery of the cup lid has a double-layer annular lid edge which has an inner layer and an outer layer, and an annular engaging space facing down is formed between the inner layer and the outer layer; the engaging space further has an engaging edge protruding from the outer layer, and the inner layer is directly connected to an annular groove; a clamping groove formed at a lower surface of the cup lid passes through a center of the cup lid and connects the annular groove at two ends thereof, and the clamping groove further has two elastic pieces formed on two lateral walls thereof; two closed top portions of the cup lid are respectively formed at two sides of the clamping groove and surrounded by the annular groove, and a crease is formed along a middle line of the clamping groove to connect the lid edge at two ends thereof.
