Abstract

PURPOSE: To plan the saving of material and the simplification of the opening action, by drawing three circles of the same radius centering at each of vertexes of a small equilateral triangle, by drawing three common tangents to each couple of adjoining two arcs among three arcs laying outside in a row, and by constituting the original profile of the crown cap with arc-tangent-arc-tangent-arc-tangent in this order.
CONSTITUTION: Three circles 5 in the same radius are drawn centering at each of three vertexes 2, 3, 4, of a small equilateral triangle 1; the common tangents 7 are drawn to adjoining two arcs among three arcs 6 lying outside in a row; then the original profile of the crown cap is constituted with arc 6 - tangent 7 - arc 6- tangent 7 - arc 6 - tangent 7 in this order. The crown cap is blanked from a tin plate, etc., in thus constituted original profile; hereby, the consumption of material such as the tin plate, etc., is saved by about 3% as compared with the conventional original profile of the crown cap. Moreover, thus formed crown cap can be extremely easily opened.
