Using the container portion as a finger grip, the flaps may be moved about the desired surface, spreading the dispensed ingredient. In some embodiments the outlet is opened by squeezing the container sides to break a closure seal (19). In others the outlet is unsealed by pulling the flaps apart (19'); by tearing (35) or is unblocked (57) by unfolding the flaps. In a preferred embodiment the container and applicator combination is formed by a pair of flexible foil sheets of substantially identical structure (21 & 23) that are superimposed over one another and partially connected together to define both the container and the applicator.Type: GrantFiled: December 2, 1998Date of Patent: December 28, 1999Assignee: Felix Investments, LLCInventor: Kurtis James Koptis

Patent number: 5997205Abstract: In order to supply a coating to a roller, a coating supplying groove is provided along only one side of a core which is connected to an end of a support so as to act as a shaft of a roller. A coating reservoir between the roller and the core is located to one side of the core. To permit engagement and disengagement between the support and the core, an elastic member is mounted within a coating flowing hole of the core, while an inserting groove and a stopping groove are provided in the inner peripheral surface of the coating flowing hole of the core. To automatically stop and start the supply of coating to the coating roller, and to adjust the flow rate, the number of revolutions of the roller are detected and used to actuate the coating feed mechanism to supply coating at a flow rate corresponding to the number of revolutions and or direction of rotation of the roller.Type: GrantFiled: March 25, 1998Date of Patent: December 7, 1999Inventor: Takanori Koide

Patent number: 5988212Abstract: A metal bellows is located in a chamber of the housing. A channel connects its inner space with the ambient. The gastight metal bellows ends at a reaction area disk. A pivoting arm with a baffle plate is pivotably mounted at one end to the housing. Its opposite end is coupled to the reaction area disk. Pressurized gas flows out of an outlet nozzle against the baffle plate and into the inner chamber of the housing and acts upon the reaction area disk. The pressure in the inner space of the chamber depends from the distance between the baffle plate of the upwards pivoted pivot arm and the outlet nozzle. This pressure is balanced by the counter-force of the circumferential wall of the metal bellows acting as spring member. Accordingly, the pressure of the fuel gas stored in a gas cylinder is reduced at the gas outlet of the housing to a preset pressure, from which gas outlet the fuel gas is led through a conduit to a gas burner.Type: GrantFiled: August 27, 1998Date of Patent: November 23, 1999Assignee: Boa AGInventors: Hans-Rudolf Drayer, Dimitri Dutat
