TECHIVICAL FIELD
The present invention refers to a threaded device to be applied on bottle's
necks that are
unprovided of threading and is therefore included in the lnt:ernational
Classification B 65
d.
STATE OF THE ART
Is it know that bottles with unthreaded neck deal with the problem of hermetic
reclosing.
The solution offered by the present invention allows in simple and inexpensive
way to
apply on bottles an externally threaded device that provides the upper edge of
the neck
with a threading that allows to screw appropriately threaded capsules in order
to allow
the hermetic closing of the bottles.
DESCRIPTION
The invention is disclosed in the following detailed description, with
referenc<; to the
figures o the attached drawings, is not limiting examples.
Fig. 1 represent in section a bottle's neck upon which was applied a threaded
device on
which is screwed a appropriately threaded capsule, in order to ensure the
hermetic
closing of the bottle.
Fig. 2 is an external view of the threaded device.
Fig. 3 is a plan view of said device that highlights the option of inserting
it on the side to
the bottle's neck.
In the figures each detail is marked as follows
1. is a bottle's neck ;
2. is a threaded device to be applied upon the bottle's neck ;
3. indicates the external threading of said device ;
4. indicates the upper eounterboring surface of said device ;
5. indicates the lower edge of the neck's collar that match with the upper
surface 4 ;
6. indicates the surface of the upper edge of the bottle's neck ;
7. indicates the lower sealing surface of the closing capsule that matches
with the edge 6.
in order to ensure the hermetic closing, obtained by applying the two
congruent
threading ;
8. indicates a closing capsule screwed on the threading 3, of the device
applied on the
bottle's neck.
