The lid assembly also has an independently formed handle hingedly connected to the lid for carrying.
Claims8
An integral molded plastic lid comprising:
- a top wall having a circumferential side wall depending therefrom for mounting over an open upper end of a container, said top wall having a first and second recess formed therein;
- said top wall having a first upwardly extending hollow wall section within said first recess having an open lower end of a sufficient size to allow pouring therethrough when said lid is mounted on said container;
- said first upwardly extending hollow wall section having an internal circumferential sealing groove between an upper and lower end thereof;
- a first closure hingedly mounted within said first recess and having a first plug depending therefrom corresponding in shape to said first upwardly extending hollow wall section, said first plug having an inner and outer end thereof for engaging said upper and lower end of said first upwardly extending hollow wall section in frictional engagement;
- said first plug having an external circumferential sealing ring between said inner and outer end thereof for engaging said sealing groove in snap fitting engagement;
- said top wall also having a second upwardly extending hollow wall section within said second recess having an open lower end of sufficient size for the insertion of a drinking straw therethrough when said lid is mounted on said container;
- said second upwardly extending hollow wall section also having a circumferential sealing groove between an upper and lower end thereof;
- a second closure hingedly mounted within said second recess and having a second plug depending therefrom corresponding in shape to said second upwardly extending hollow wall section, said second plug having an inner and outer end thereof for engaging said upper and lower end of said second upwardly extending hollow wall section in a frictional fit engagement;
- said second plug having an external circumferential sealing ring between said inner and outer end thereof for engaging said sealing groove in said second upwardly extending hollow section in snap-fitting engagement.
