Abstract: PROBLEM TO BE SOLVED: To prevent the liquid leakage from an air substitution route by disposing an outdoor air introducing part of the air substitution route for lading the outdoor air into a container body on the side opposite to a nozzle part around the mounting center of a trigger sprayer to the container body. SOLUTION: The trigger sprayer 13 has a trigger 25 in the lower part on the front surface side of a pump housing 6. The air substitution route 40 for executing the air substitution by pulling a trigger 25 is formed with a toric space demarcated around a liquid pass tube 18 by an inside plug 10O sealed into a lower flange part 17A of a liquid passing body 17 and is provided with the outdoor air introducing hole 41 of the air substitution route 40 and an air substitution operation section 42 on the side opposite to the nozzle 31 around the mounting center of the liquid passing body 17 to the aperture 11A of the container body 11 forward. Then, even if the container body 11 is used by inclining the body, a liquid level does not arrive at the side opposite to the nozzle 31 of a trigger sprayer 13.  As a result, the liquid leakage from the air substitution route 40 does not arise at the time of using the container body 11 by inclining the container body forward.

Title: Device and method for collecting member of electronic substrate
Inventor: MORI HIDEKI
IPC: B09B5/00
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To efficiently collect solder without deteriorating it owing to oxidation by heating nitrogen gas or inert gas, spraying it on an electronic substrate and removing melted solder. SOLUTION: A nitrogen gas circulation circuit 2 being one example of a circulating circuit is installed in a solder collection device. The nitrogen gas circulation circuit 2 heats nitrogen gas supplied from a nitrogen gas bomb 4 in a heat exchanger 5 of a heating means. An gas supply fan 6 sprays hot nitrogen gas to the lower part of an electronic substrate 11 having loading parts 12. A suction pump 9 executes a driving operation for supplying gas circulated in the circuit again as heating gas. Since hot gas sprayed to solder face is nitrogen gas with such constitution, the oxidation of collected solder 13 can be suppressed. Since heat accompanied by heating is difficult to be transmitted to the loading parts 12, the damage can be suppressed.
