Jolt container (3)
I believe the answer is:
jar
I believe this is a double definition.
'jolt' is the first definition.
(synonyms)
'container' is the second definition.
(jar is a kind of container)
(Other definitions for jar that I've seen before include "Wide-mouthed vessel" , "Enduring courage" , "Glass of beer (colloq.)" , "Wide-mouthed container" , "Jolt with glass container" .)
