tion when it is required to gain access to the
contents of the bottle or package. It is pre-
ferred to make the shoulder 7 exceedingly
thin, whereby it may be easily cut by means
5 of a knife or -other instrument.
The cap 4 may be formed of any material,
aluminium being preferred, since it precludes
the soldering or the ready attachment of the
metal portion of the cap to the peripheral
io portion after said parts have once been sepa-
rated. When the rim 5 is pressed into the'
groove 1, the interlocking portion 6 is com-
pressed, and when the shoulder 2 is cleared
the part 6 springs outward thereunder and
15 interlocking therewith prevents removal of
the cap, thereby rendering it necessary to cut
the raised portion of the cap from the periph-
eral portion when it is required to gain access
to the contents of the receptacle. The accus-
20 tomed stopper 8 may be employed to close
the neck of the bottle, although this is not
essential. To give additional security, it is
contemplated to fill the groove 1 with any ce-
menting substance which will set and become
25 hard, thereby securing the parts 5Sand 6 within
the groove by cementation in addition to the
interlocking feature between the shoulder 2
and part 6.
As herein stated, after a bottle or package
30 has been sealed in accordance with this in-
vention it cannot be opened without cutting,
marring, or mutilating the cap, thereby ren-
dering detection certain in the event of the
package being tampered with.
35 In the modification shown in Fig. 7 the in-
terlocking portion 6 is made separate from
the cap, but rigidly secured thereto. This
construction admits of having the cap of one
metal and the interlocking portion of another.
4o The advantage derived from the above is
that the cap proper may be made of a light
metal, such as aluminium above mentioned,
and the locking part 6 of some metal possess-ing much rigidity and at the same time great
spring or resilient properties-namely, steel 45
or the like.
Having thus described the invention, what
is claimed as new is-
1. A bottle or like package provided with
an upwardly-opening groove in its upper end, 50
the walls of said groove being contracted at
the upper portion thereof, and a cap having
a rim to enter said groove and interlock with
a wall thereof, substantially as set forth.
2. A bottle or receptacle having a groove 55
opening upward through its top portion, the
walls of said groove being contracted at the
upper portions thereof, and a cap having a
rim to enter said groove and having a spring
interlocking portion extended from the lower 6o
edge of the rim to engage under the project-
ing portion of the wall of said groove result-
ing in contraction thereof, substantially as
set forth.
3. A bottle or receptacle having an up- 65
wardly-extended groove in its top portion con-
tracted at the upper portions of the walls there-
of, and a cap having a rim to enter said groove
and having a series of tooth-shaped projec-
tions extended upwardly from the lower edge 70
of said rim to interlock with the contracting
wall of the groove, substantially as specified.
4. A bottle or package provided in its up-
per end with a groove, and a cap having a
rim secured in said groove and having its 75
middle portion raised or pressed upward to
form a shoulder to facilitate severance of the
central portion of the cap when opening the
package, substantially as described.
In testimony whereof I affix my signature 8o
in presence of two witnesses.
