I, HUGO ECKE, of 5 Marcusstrasse, Berlin O, Germany, Merchant, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
My invention relates to improved appliances for securing the stoppers or other
closures of bottles, jars and similar receptacles, whereby the unauthorised with-
drawal of the contents is prevented. The invention consists mainly in enclosing
the stopper, cork or other ordinary closure of the receptacle by means of a cap,
operating, in combination either with a ring on the neck of the bottle or with an
appliance on the stopper of the bottle and a locking device in such manner that
the cap is locked in position until, by means of a.key, the locking device is released
so as to allow the cap to be rotated. to a certain extent.
The nature of my improvements. for this purpose will be readily understood on
reference to the accompanying drawings.
.
The neck of the bottle or receptacle is provided with an external screw thread,
and with a longitudinal groove a, cutting through the thread as shewn at Figs. 1
and 2. An annular nut b, provided with a corresponding internal thread, and with
a groove a, as at Figs. 3 and 4 is screwed on to the neck until this projects some-
what above the nut b while at the same time the two grooves a and a¹ are
brought opposite each other so as to form a closed channel, into which is theu
passed a tapering spring or pin c, Fig. 11, so as to prevent the nut from further
rotation. Upon the external screw thread d of the nut b is then screwed a cap e,
Figs.. 9 and 10. which is provided at one side with a small lock f. The bolt of the
lock fiu locking, enters an opening g.in the nut b and thus prevents the rotation
of the cap e upon the nut. The cap e thus encloses the upper end of the groove a
and prevents the removal of the spring, or pin c. For gaining access to the contents
of the bottle it is only necessary to unlock the lock and screw off the cap e.
nut 6 can always remain attached to the neck of the bottle..
The
Figs. 5, 6, 7, 8 and 12. shew another nude of preventing, the rotation of the
But b. In this case the upper screw throads of the neck are interrupted by a flat.

page_text: surface has shewn at Figs, 5 and 6. The nut b is provided with a slot i forming a
tangent to the bottom of the screw thread as shewn at Figures 7 and 8 and when
the nut is screwed on so as to bring this slot in line with the surface h a slightly
tapering pin or key is passed laterally through the slot and against the surface h
thus preventing the rotation of the nut upon the neck. On screwing on the cap e
this encloses the ends of the slot i and thus prevents the removal of the piu. The
cap is secured by means of a lock f as before. The closure of the opening of the
bottle is quite independent of this device for securing the same and may consist
either of a ground stopper or of a cork or other device. The stopper may however
be conveniently. combined with the cap e. Fig. 13 shews. a modification for
securing the neck or opening of a wide mouthed bottle or receptacle containing
pulverulent or other material. For, hermetically enclosing materials that deteriorate
by contact with the atmosphere a packing ring o is interposed between the annular
nut m and the neck of the bottle and also between the upper end of the nut and
the cap n.
The nut is prevented from turning by means of the pin r and the cap n
is secured to the nut by means of a lock 8.
For applying the device to the neck of a bottle having no external screw thread,
the neck of the bottle is formed with a groove like that of a bayonet catch as
shewn at Figs. 14 and 15 into which passes a stud u on the ring 6 Figs. 16 and 17
and after turning the ring so that the stud passes into the horizontal part of the
groove a pin or key vis inserted into the vertical part, thus effectually locking
the ring in position. Or the arrangement as shewn in Figs. 20 and 21 may be
employed in which the ring is locked in position by passing a dovetail key or pin x
through a dovetail groove in the ring and a corresponding dovetail groove w in the
neck of the bottle. The cap e is in this case also locked in position without the
use of a screw thread by providing it with a stud y fitting into a bayonet catch
in the ring. The ring is shewn separately at Figs. 18 and 19 the turning of the
cap is in this case also prevented by means of a lock f the bolt of which enters a
notch g. in the ring..
Figs. 22, 23 and 24 shew an arrangement for effecting a hermetic closure of the
bottle in such manner that the contents of the bottle do not come in contact with
the metallic part of the closure. The ring b is secured to the bottle in any one of
the before described ways. It is provided with two grooves a¹ which corresponds
with the two grooves b¹ of the cap e. Into the grooves b¹ pass lugs c¹ formed on
the sides of the inner cap which is provided on its underside with a caoutchouc
disc e. The inner cap d' has connected to it the screw f' so that the latter is free
to rotate, but in being screwed upwards in the outer cap e it will raise the inner
cap d'and it will press the latter hermetically against the mouth of the bottle on
being screwed downwards. The socket g¹ formed in one with the cap e and
through which the screw f1 is screwed is so narrow that the screw can only be
turned by means of a special key h¹. The cap e can only be rotated so as to be
taken off when the lugs in being raised by the screw f1 pass out of the grooves a¹
of the ring b.
:
:
Figs. 25, 26 and 27 shew a similar arrangement to that above described applied
to the mode of fixing the ring b described with reference to Figs. 20 and 21:
When the receptacle contains strong acids that would injure the metal of the
ring bif it came in contact therewith it is advisable to dispense with the ring h
and employ the construction shewn in Figs. 28 to 34. The neck of the bottle 'has
two diametrically opposite hook-shaped grooves similar to those described
with reference to Fig. 14, into which pass studs projecting inward from the
cap c.
The inner cap d' has two lugs c¹ which are situated at a distance from the
studs equal to the length of the horizontal groove k¹ so that when the cap e has
been turned to its extreme position with its studs in the groove k¹ the lugs c', in
screwing down the inner cap d¹, will enter the grooves i¹ and thus prevent the
back ward motion of the studs in the groove k¹. On Figs. 32, 33 and 34 the
screw f¹ described with reference to Fig. 22 is replaced by an eccentric pin m'
which, on being rotated by means of the key h² raises or lowers the inner cap d'
.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. The use in combination with bottles or other receptacles, of a cap enclosing
the stopper or other closure and so arranged in combination either with a ring on
the neck of the bottle or with an appliance on the stopper of the bottle, and with
a locking device, that for removing the cap it requires to be rotated somewhat,
which rotation is prevented until the locking device is released by means of a key,
substantially as herein described.
2. The use in combination with bottles or other receptacles of a cap enclosing
the stopper or other closure, and secured by a locking device to a ring that is in its
turn secured to the neck of the bottle by a pin or spring, which is also enclosed by
the cap, substantially as herein described with reference to Figs. 1 to 13 of the
drawings.
3. Constructing the necks of bottles or other receptacles with a bayonet-catch
groove t or with a horizontal groove w for securing an external ring by means of
either stud u and pin v or a dovetail key x, as herein described with reference to
Figs. 14 to 21 of the drawings.
4. The use in combination with an outer cap e and ring b of an inner cap d'
actuated by a screw f on the cap and having lugs c¹ entering grooves on the ring b
and in the cape so that when the cap d' is screwed down the lugs c¹ prevent the
cape from being rotated for its removal, substantially as herein described with
reference to Figs. 22 to 27 of the drawings.
5. The use in combination with an outer cap e, with studs fitting in bayonet-
catch grooves on the neck of the bottle, of an inner cap d' actuated by a screw f
on the cap and having lugs centering grooves on the neck of the bottle and in
the cap e, so that when the cap is screwed down the lugs c¹ prevent the cap e
from being rotated for its removal, substantially as herein described with reference
to Figs. 28 to 31 of the drawings.
6. The combination with the outer cap e of the inner cap & hermetically secured
on the mouth of the receptacle by an eccentric pin m on the cap e, the inner cap d¹
being provided with lugs or studs c¹ that enter bayonet catch grooves in the neck
of the bottle, when the cap d¹ is screwed down, and thereby lock the studs of
the cap e in such grooves, substantially as herein described with reference to
Figs. 32 to 34 of the drawings.
