IPC: B65D41/04
Filed: 1995-02-20
Abstract: PURPOSE: To enable setting a cap in position on a container body without damaging the capping device in screwing up the cap on the container body by putting a ring-shaped plane part of the container body against a ring-shaped projection on the cap. CONSTITUTION: A cap 120 is set on the neck 111 of a container body 110 by fitting together their mutual screws 123, 113 by the use of a capping device. In thus setting the cap a ring-shaped triangular projection 125 on a ring-shaped plane part 124 provided between a screw 123 on the inner side of the cap 120 and the top side 121 is put against a ring-shaped plane part 114 provided between a screw 113 on the outer side of the neck 111 and the upper end 112 with the result that the pouring hole of the cap 120 is positioned in alignment with a specific direction with respect to the neck 111. Moreover, since the ring-shaped triangular projection 125 is pressed against the ring-shaped plane part 114 when the cap 120 is set on the container body 110, the ring-shaped triangular projection 125 serves to prevent leakage of liquid contained in the container.

Filed: 1980-03-12
Abstract: PURPOSE:To obtain a multiple interconnection with a fine pattern by filling a thermosetting resin between the first wiring layer and a surrounding insulator layer before the formation of the second wiring layer. CONSTITUTION:Openings are made on insulator films 2 and 5 to form the first wiring layer 3'. First, a liquid organosiloxane resin is applied by turning and heated to form a resin film 7 whereby a flat surface is obtained. Then, a plasma etching is made by CF4 to expose a wiring layer 3'. As the organosiloxane resin tends to be cracked when exposed to O2 plasma, a dry etching never generating the O2 plasma shall be selected. Thereafter, according to the accepted method, after the resin is covered with PSG8, an electrode window is provided to make the second layer wiring 9. With such an arrangement, the second layer wiring is formed on an extremely falt surface thereby eliminating disconnection and disturbed pattern and ultimately assuring a fine pattern.
