Patent ID: 7461757

Claim:
A self-retentive straw and beverage container combination, said combination comprising: a beverage container having a closed end, an open end, an interior wall and an interior cavity; a container lid having a central aperture, said lid operates to fasten to said open end of said container; and a self-retentive straw having: an intermediate portion having a first end and a second end; a first convoluted portion extending from said first end of said intermediate portion; and a second convoluted portion extending from said second end of the intermediate portion, said second convoluted portion configured to allow the lid to be received onto the intermediate portion, the interior wall being contoured so that the width of the cavity as measured along a line normal to an axis extending from the closed end to the open end varies as a function of the distance from the closed end; whereby the second convoluted portion abuts against diametrically opposed sections of said interior wall of the container to prevent the straw from being easily removed from the container when the straw is installed into said interior cavity of the container and the lid is attached to the container while permitting the straw to be readily removed when the lid is not attached to the container.
