4 Claims. (Cl. 215-45)
The present invention relates to closures for
discs l5 and I6, connected together by rivets or
sealing bottles and like receptacles, which are ' other suitable means, and the upper disc I5 is
applied exteriorly on to the mouth of the bottle
or the like and has for its chief object the pro
vision of an improved stopper which will per
mit of the sealing and unsealing the receptacle
a great number of times, while always affording
a perfect hermetic seal.
The closure according to the invention com
10 prises essentially a metal cap inside which is
disposed an elastic member having a number of
in turn connected to a U-shaped member H,
which projects upwards and traverses the up
per part of the cap projecting to the outside.
in
In the extremities of this U-shaped member
there is disposed a spindle or pin l8 serving as
a pivot for an eccentric I9 connected to a lever
2|! and so disposed that upon actuation of the said
lever the eccentric bears against ‘the upper part 10
of the cap I0, preferably through the interme
diary of a washer 2|, and lowers the cap III in
curved lugs, the said elastic member being com
bined with an eccentric actuated from outside by relation to the elastic member l2, thus causing
the lugs of the said elastic member to become
means of a lever, whereby the elastic lugs en
15 gage a ?ange disposed exteriorly on the neck of locked by their engagement with the conical
the bottle, a hermetic seal being obtained by the surface II and, consequently, to engage ?rmly
interposition of a washer or disc of rubber 'or on the ?ange 22 of the neck of the bottle or
other suitable elastic material between the said receptacle 23.
Furthermore, in order to obtain hermetic seal
member and the mouth of the bottle.
The action of locking the curved lugs in order ing, there is disposed between the elastic mem
20
that they may engage on the ?ange oi the neck her and the mouth of the bottle a washer or disc
24 of rubber or other suitable elastic material,
of the bottle is obtained by the special arrange
ment of the outer cap of the closure, which has which is normally held in position in the stopper
a conical portion ?tting on the curved part of by the same curvature of the elastic lugs.
In the modi?cation shown in Figure 4, instead

actuation of the eccentric the elastic member of the full rubber disc 24 of Figures 1 and 2,
is forced into the cap, the pressure of the conical there is employed a rubber washer 30 which in
portion thereof thus bending and locking the lugs its central part bears a cup like piece 3| of
of the elastic member. Subsequently, in order aluminium or other suitable material. This ar
30 to withdraw the closure from the bottle, it is rangement prevents the liquid in the bottle
from touching the rubber, but in other respects
su?icient to actuate the eccentric in the oppo
site direction, whereupon the pressure acting on is fully equivalent to the arrangement of Fig
the elastic lugs is relieved and the lugs leave the
?ange of the bottle.
A form of construction of the closure accord

the position in which it is mounted on the bottle.
The lever 20 actuating the eccentric may be
of any desired form, preferably curved, as shown
in the accompanying drawing in order that once
the bottle is sealed this lever may ?t against the
neck thereof without causing any obstruction.
Moreover, in the said lever there is also pro

The closure is constituted by a cap "I sub- ~ in Figure 3, which has the form of a small re

serves for the presentation of the closure for sale

Inside this cap is disposed an elastic member in attractive form and may be so disposed that,
