Document Type and Number:
Japanese Patent JP3493003
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To allow a viscous substance filled in a container to be simply squeezed in a predetermined quantity.
SOLUTION: The nozzle 1 and the container are integrally formed by sticking a pair of triangular films. In addition, a surface of the nozzle 1 is divided into color-coded annular areas. The nozzle 1 comprises a plurality of nozzle ports 3 to 6, each of which has opposite regions 3a to 6a and 3b to 6b. The opposite regions forming the ports 3 to 6 are formed in parallel, and a predetermined height is kept on the port 3 by the opposite regions 3a to 6a and 3b to 6b. Further, the opposite regions are gradually narrowed. The widths between the opposite regions are thus varied, thereby forming the nozzle ports 3 to 6 stepwise and reducing their widths toward the tip.
