Abstract: A sports container has a top and a bottom container portions, the two portions of approximately equal size and joined at a midline of the container forming abutting cutting plain surfaces. Each of the portions provides a cavity, the cavities formed in mirror image relationship. One of the cavities provides a peripheral lip extending from the cutting plane surface and has an outwardly convergent cross-section. The other of the cavities provides a peripheral groove extending into the cutting plain surface and has an inwardly convergent cross-section. The container is made of a pliable and resilient foam material having a skin. The lip has a girth exceeding that of the groove, wherein the lip is compressed upon entry into the groove when the portions are mated. The portions are secured together by the gripping of the lip by the groove.
