' (01. 220-43) This invention relates to receptacle openers of the pry-bar type for cone-type-friction seal plugs employed to close or seal such receptacles, and also to the combination of such an opener with 5 a special construction of such a sealing plug. ' The primary objects of the present invention are to provide such an opener which may be freely moved peripherally about the rim or bead of the plug to be used to successively pry against 10 the end of the receptacle at different points ad jacent the periphery of the plug and which will remain at all times permanently though loosely applied to the plug so as to be removed therewith and applied therewith to the receptacle, whereby 15. the receptacle may be opened and resealed re peatedly a number of times and the opener will always be available to facilitate the opening; to provide such an opener which will not injure the top of the receptacle nor scratch or mar the ?nish of the said top; to provide an opener having a sti?ly resilient prying leg and foot bearing with a cam action on the top of the receptacle and exerting a spring pressure in the ?nal stages of its operation vto aid in lifting the sealing plug, such resilient characteristic also contributing to the avoidance of marring the ?nish of the top of the receptacle; to provide such'an opener which will not tightly frictionally engage any’edge, face or portion of the plug or top of the receptacle in 39 its retracted or inoperative position or in any intermediate position when not exerting inten tionally a lifting leverage on the top of the re , ceptacle, whereby the opener may be freely and easily shifted in a peripheral direction from point 35 to point about the periphery of the sealing plug without jamming or binding or sticking in one position and without risk of being damaged or twisted by the exertion of too much force by the operator in his impatience in trying to shift it 40, peripherally and which, if the opener jammed in position might result simply in twisting the opener off of the plug and destroying its further‘useful ness instead‘ of sliding it peripherally about the result otherwise in their deformation and separa tion. ‘ Herein I illustrate and describe simply the pres ent preferred embodiment of my invention merely by Way of illustration of the practice of my in- 5 vention as by law required. However, I am well aware that my invention is capable of various ' embodiments and that the several details thereof may be modi?ed in different ways, all without departing from my said invention, and, there- 10 fore, the accompanying drawing and description herein are to be considered as merely illustrative and not exclusive.
