CLE FOR CL SUR Patented Mar. 30, 1937 RECEPTACLE FOB gAIPlSURE BY SEALING Robert Landau, Paris, France Application December 4, 1933, Serial No. 700,890
In France April 22, 1933 2 Claims.
This invention relates to improvements in receptacles, and more particularly bottles, of the Vtype adapted to be sealed by means of a closure cap. In the known receptacles of this type the head portion is either tapered outwards or cylindrical from the orifice downwards, and is then constricted to provide an overhang beneath and into engagement with which the marginal portion of the ange of the sealing cap can be bent or crimped to form a closure. In order to effect the gas-tight closure of receptacles the contents of which are under considerable internal pressure, this constriction on the head of the receptacle must be very pronounced to permit of' adequate crimping and anchoring of the cap, which circumstance gives rise to the drawback that the head portion of the receptacle is easily broken, in removing the cap, and also that the cap itself is inevitably demolished and rendered absolutely unfit for further use. Y
Receptacles are further known in which the rounded head portion merges into a more or less sharp-edged beading. Such receptacles, however, are only suitable for use in connection with special types of closure cap either having a proled packing ring associated with the cap flange and.
adapted, on rotation of the latter, to be brought into engagement beneath the said beading, or having a tinned cap flange so dlmensioned that when the cap is forced over the said beading, some of the tin plating is rubbed off into the roughened surface of the beading and the marginal portion of the flange contracts slightly of its own accord beneath the beading.
'I'he present invention provides a receptacle Vcharacterized by the essential feature that the upper portion of the neck or head adjacent the orifice is externally cylindrical or in the shape of an inverted frustum of slight conicity, and terminates in an abruptly shouldered beading the lower side of which is suitably curved to provide a -bearing surface for the inwardly bent marginal portion of the cap flange. The receptacle according to the invention can be sealed with any type of cap having a flange or rim portion adapted to be crimped or bent inwards into engage' time ensuring that, in being removed, the cap is not deformed to such an extent as to prevent its subsequent reuse.
'I'he headportion of a receptacle in accordance with the present invention is shown. by way of example, in the accompanying drawing, in section.
'I'he receptacle, for example bottle, glass, or the like, tov be sealed by means of a closure cap possesses a head portion a the outer surface a' of which is in the shape of a straight-line cylinder or of an inverted frustum. Adjoining the outer surface a' there is provided a beading c which is abruptly. shouldered on the upper side, and which' on the under side merges in the neck b of the receptacle with a gentle curvature d. This olf-set beading c together with its curved under side d takes the place of the deepv constriction, groove, or the like provided in the usual known types of receptacle for the engagement and retention of the closure cap, and that without in any way weakening the neck of the receptacle. For the readier understanding of the advantages provided by the particular shaping of the receptacle in accordance with the present invention, there is shown in broken lines in the drawing a closure cap e of a known type having indentations f in the cylindrical ange g for the purpose of increasing the retaining pressure against the side of the neck of the receptacle, although this receptacle is equally well suited for use in connection with any other type of closure cap having a ange portion, such for example the usual crown-corks. The head a, in consequence of its cylindrical or frustum shape, provides around the orice of the receptacle a wide bearing surface a" for the gasket h destined to be compressed between this surface and the head of the cap, while the cylindrical outer surface a of the head a serves as a bearing surface for the ange a of the cap or for its indentations f, and facilitates the application and removal of the closure cap e. The extent to which the beading c is off-set from the cylindrical surface of the neck, and the curvature of the under side d of this beading are so determined that the rim lc of the cap flange, during the original sealing operation, is not bent in or crimped so sharply or to such an extent that the removal of the cap is rendered diiilcult, and are also so determined that the cap, in being -removed, is not deformed to such an extent as to prevent its being used again. Deformation to this extent is avoided if the crimped edge k be not strained beyond its elastic limit during the partial rotation of the cap vabout the point on the edge of thc ange opposite that to which the operative portion of the known cap-removing implement is applied removing the cap. On the other hand, the curved under side of the 5 beading must be so shaped as to permit of the cap rim k being bent inwards to such an extent that the cap ensures the gas-tight sealing of the receptacle even when the contents thereof are under high pressure, such as occurs, for example, in the pasteurizing of beer. The beading c and its curved under side d are thus given the described and illustrated shape which has been found to permit of the repeated employment of the cap after removal from its original sealing position. For the purpose of this subsequent use,
the cap is forced into position by hand, the rim lc of the flange being caused to spread slightly by the beading, and snapping 4into position automatically beneath this beading with an audible sound of engagement.
A further advantage of the fact that the retaining bead is abruptly shouldered on its upper side is that the crimping or bending in of the marginal portion of the cap ange beneath this bead tends to bring about automatically a certain amount of constriction of the portion of this flange immediately above the bead, thus ensuring a particularly close t and the avoidance of any hollow spaces between the cap flange and the neck of the receptacle, such as occur with the known types of receptacles having a beaded orice or head portion.
A further feature of the invention consists in the provision oi improved means for ensuring better packing of the orifice of the receptacle than is effected vby the mere clamping of the cork gasket h in the usual manner between the mouth of the receptacle and the head of the cap. To this end there is provided in the interior of the orifice of the receptacle a ledge of undercut or toothshaped cross-section m. which is so disposed intermediate the levels of the upper bearing edge a" and of the bead c that the portion of the gasket h caused by the pressure of the cap to bulge into the orifice of the receptacle is pressed rmly into engagement with this ledge m without being thereby damaged or cut through, thus very greatly improving the packing effect.
I claim:
1. A receptacle closure comprising in combination a cap of resilient material having a dependent cylindrical iiange adapted to be bent inwards into gripping engagement with the receptacle, a compressible gasket in the said cap, a neck portion adjacent the mouth of the receptacle, the side surface of the said neck portion being substantially cylindrical and its end surface adapted to serve as a bearing surface for the said gasket, an outwardly projecting annular beading adjoining the said neck portion, the said beading being abruptly shouldered-out on the side nearest the mouth of the receptacle and gradually curved on the side remote from the said mouth, the upper edge of the said beading being adapted to slightly spread and to be irmly engaged by the said flange and the gradually curved under side thereof to be engaged by the bent-in portion of the said flange, and an annular ledge on the inside of the said mouth adjacent the said bearing surface and adapted to be engaged by the said gasket.
2. A receptacle closure as claimed in claim 1 in which the said ledge is of tooth-shaped crosssection with its pointed end upwardly inclined.
