摘要： PROBLEM TO BE SOLVED: To discharge an edible material without moving a pastry case of a egg roll by a conveyer in an edible material-discharging nozzle for discharging edible ingredients of the egg roll, etc., in long and narrow state on the pastry case for wrapping the edible material. SOLUTION: A nozzle body 1 is formed so that the cross section gradually changes from circle to elliptical form from edible material-feeding pump connecting side toward edible material output side and a rubber nozzle 2 having a long edible material discharge port 2d is covered on the edible material output side to attach the rubber nozzle to the nozzle body and a pressing metal fittings 3 and stopping metal fittings 4 are successively fitted into the upper end part. Since an edible material fed from a pump is discharged laterally from the edible material discharge port 2d in long and narrow state, it is not required to receive the edible material vertically discharged in long and narrow state while moving the pastry case by the conveyer.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of leakage of LPG due to the reverse flow of LPG of other bombs through a pipeline by connecting a high-pressure hose and a pipeline to each other with a pipe joint with a built-in check valve. SOLUTION: High-pressure hoses P1 -Pn are extended form LPG discharge ports H of plural bombs B1 -Bn , and a pipe joint J with a built-in check valve V is connected to the tip of each high-pressure hose. A check valve V is inserted into the pipe joint J at a side, to which the high-pressure hose P is connected, and a spring S for energizing the check valve V in the direction opposite to a valve seat Vm is inserted in the pipe joint J. An opening part O is provided with a screw Sc for connecting the high-pressure hose P and a pipeline L to each other. Even in the case where the high-pressure hose P1 , which is connected to the bomb B1 , is broken, the pressure inside of the high-pressure hose P1 becomes as same as the atmospheric air pressure, and LPG of other bombs B2 -Bn is reversely flowed through the pipeline, and the pressure thereof is applied to the check valve V, and the energizing force of the spring S is relatively reduced so that the check valve V is pushed to a valve seat Vm, and as a result, reverser flow of the LPG is interrupted.
