Abstract
A button fastener for use with a storage carton having a stud on one button member which is extended through the side wall of the storage carton. Another button member then is engaged with the stud so as to receive the stud in a bore in it and the two button members are pressed together to force the stud through the bore until locking shoulders formed by an enlarged head on the stud and the cavity about the bore lockingly engage with one another to affix the two button members together. A longitudinal slot in the stud and the enlarged head on it permits the enlarged head to be sufficiently compressed together to be extended into and through the bore, and to then expand to engage the locking shoulders. Conical walls of the enlarged head also assist in inserting the enlarged head into the bore. The enlarged head on the stud is contained substantially or completely within the cavity about the bore and is thereby prevented from puncturing or otherwise damaging the side walls of the storage carton.
