Abstract
Official abstract text for this publication.
A gas injection device a placement portion on which a first or second container is placed, an ejection portion which is placed on the placement portion and ejects a purge gas, and a sealing portion protruding from the placement portion so as to surround a periphery of the ejection portion. The ejection portion, with the purge gas being injected into an inlet of the second container, does not come in contact with the inlet. The sealing portion, with the purge gas being injected into an inlet of the FOUP, does not impede the contact between the ejection portion and the inlet.
First claim
Opening claim text (preview).
The invention claimed is: 1. A gas injection device configured to inject a purge gas into a first inlet provided on a first container, and configured to inject the purge gas into a second inlet provided on a second container, the second inlet on the second container having a diameter larger than that of the first inlet on the first container, the gas injection device comprising: a placement portion on which one of the first container and the second container is selectively placed; an ejection portion which is placed on the placement portion and ejects the purge gas; and a sealing portion protruding from the placement portion and surrounding a periphery of the ejection portion; wherein the ejection portion is configured to come in contact with the first inlet and seals the first inlet with the purge gas being injected into the first inlet; the ejection portion is configured to not come in contact with the second inlet with the purge gas being injected into the second inlet; the sealing portion, with the purge gas being injected into the second inlet, is configured to come in contact with the second inlet or a peripheral edge of the second inlet and seals the second inlet in cooperation with the placement portion; and the sealing portion is configured to not impede the contact between the ejection portion and the first inlet with the purge gas being injected into the first inlet. 2. The gas injection device according to claim 1 , wherein the sealing portion includes an elastic body. 3. The gas injection device according to claim 2 , wherein the sealing portion includes a plate-shaped elastic body, the sealing portion is configured to be tilted towards the ejection portion with the purge gas being injected into the second inlet, and includes a leading end portion configured to be positioned into the second inlet and to come in contact with the second inlet. 4. The gas injection device according to claim 1 , wherein the sealing portion is spaced away from the periphery of the ejection portion.
