I don't really see any google results for that except ones that seem to come from the same dictionary source database that Jisho uses.
The BCCWJ has 3 instances for キープボトル, and 0 for キープボットル. So even キープボトル is a pretty rare word, but it does appear to exist.
Not that inconsistencies in katakana words are impossible. But in this case, I don't see much to support what is listed here.
Yes, キープボットル is wrong, キープボトル is right.
I've amended the entry in the JMdict database and it should hopefully roll out in the next few days. Thank you togaru for posting about this. In the future, if you find something wrong with any entry, remember that you can edit it/leave a comment/question directly on EDRDG.org - http://www.edrdg.org/jmdictdb/cgi-bin/updates.py?svc=jmdict&sid=
JMdict editors don't normally patrol the jisho.org forums (I came across this post entirely by chance).
Is ッ needed in キープボットル?
Isn't ボトル the right word for "bottle"?
