[0001] The present invention relates to a cap for closing a bottle or the like and to a
corresponding cap cover of the double-walled type. More particularly, the invention
relates to a cap adapted to be applied to a bottle, such as for example a bottle of
nail polish, with a corresponding cap cover.
[0002] As known, in fact, bottles have a threaded neck on which a likewise threaded cap
is usually screwed. The threaded cap can be protected by a cap cover that can have
a decorative purpose or anyway, in most cases, has the purpose of closing the cap
proper.
[0003] For example, in the case of bottles for nail polish, the threaded cap is the one
to which the brush used to apply the polish to the nails is connected.
[0004] In this case there is usually a cap cover that allows to protect the cap that will
then be gripped by the user to apply the polish to the nails.
[0005] Cap covers of the known type have a locking that usually can be provided with a coupling
by interference between the cap cover and the underlying cap. However, this coupling
is not always adequate and the cap cover can disengage from the underlying cap and
is thus lost.
[0006] Cap covers are known of the type provided by external injection in which the coupling
can be instead provided with an undercut.
[0008] In the case of double-walled cap covers of the internal injection type, the undercut
instead cannot be provided, since extraction from the mold would not be possible or
would entail such difficulties that it is not conceivable.
[0009] The aim of the present invention is to provide a cap cover with a cap, in which the
cap can be coupled conventionally on the neck of a bottle and the cap cover can be
applied externally to the cap, with a placement action that prevents its disengagement
if not desired by the user.
[0010] Within this aim, an object of the invention is to provide a cap cover with a cap
in which the cap cover is coupled in a stable manner to the underlying cap.
[0011] Another object of the present invention is to provide a cap cover with a cap that
is highly reliable, relatively easy to provide and at competitive costs.
[0012] This aim and these and other objects that will become better apparent hereinafter
are achieved by a cap cover and a cap as defined in claim 1.
[0013] Further characteristics and advantages of the invention will become better apparent
from the description of preferred but not exclusive embodiments of the cap according
to the present invention, illustrated by way of non-limiting example in the accompanying
drawings, wherein:
Figure 1 is an exploded sectional view of the cap with cap cover according to the
invention for application to the threaded neck of a bottle;
Figure 2 is a perspective view, in phantom lines, of the cap cover and of the cap
according to the invention;
Figure 3 is a plan view of the cap cover coupled to the cap, according to the invention;
Figure 4 is an exploded cutaway perspective view of the cap cover and of the cap according
to the invention;
Figure 5 is a cutaway perspective view of the cap cover coupled to the cap according
to the invention;
Figure 6 is a sectional view of the coupling of the cap and of the cap cover according
to the invention to a bottle;
Figure 7 is a sectional view of a second embodiment of the cap cover according to
the present invention;
Figure 8 is a bottom plan view of the cap cover of Figure 7.
[0014] With reference to the figures, the threaded cap with fitted cap cover according to
the invention will be described in detail, and in all the figures identical equal
reference numerals designate identical elements.
[0015] The cap of the invention, generally designated by the reference numeral 1, comprises
a body 2 adapted to be coupled, preferably screwed by means of an inner thread 3,
to a threaded neck 4 of a bottle 10.
[0016] The coupling between the cap and the bottle might also occur by means other than
a thread.
[0017] The cap rests on a shoulder 5 of the bottle with threaded neck.
[0018] In order to protect the cap 1 there is a cap cover 6, of the double-walled type,
provided by means of internal injection, which comprises a substantially tubular body
that is adapted to be fitted over the cap 1 and is provided internally with a plurality
of retentions means 7, arranged circumferentially, that allow the snap locking of
a cap cover 6 around an end rim 8 of the cap 1.
[0019] The retention means are arranged at an inner circumferential rim of the cap cover,
at the end of the cap cover 6 that is designed to be located, once coupling of the
cap cover has occurred, proximate to the base of the threaded neck 4 of the bottle
10.
[0020] Substantially, the retention means 7, which are constituted by a plurality of teeth
or wings 7, snap around the rim 8 with a sort of "click" effect, thus increasing the
tightness of the cap cover 6 on the cap 1.
[0021] The wings 7 are arranged at the inner surface of the lower rim of the cap cover 6,
which is designed to be located proximate to the threaded neck of the bottle 10 when
the cap cover 6 is fitted on the cap 1.
[0022] The wings 7 are conveniently flexible so that they can snap on the diameter of the
threaded cap 1, particularly at the end rim 8.
[0023] This solution allows quick and safe coupling of the cap cover 6 on the threaded cap
1 and a retention action by the wings 7 that prevents the disengagement, as desired,
of the cap cover 6 from the threaded cap 1.
[0024] In order to improve the coupling of the cap cover 6 on the threaded cap 1, the cap
cover is provided with a tab or fin 12 that protrudes from the inner surface of its
lower rim. The tab 12 is therefore arranged so as to protrude circumferentially from
the lower rim of the cap cover 6 and is adapted to bend, once the cap cover has been
coupled to the threaded cap 1, against the end rim 8 of the threaded cap 1.
[0025] In this manner the tab or fin 12 creates an undercut.
[0026] It is also possible for the tab or fin 12 to be compressed mechanically after coupling
between the cup cover 6 and the cap 1.
[0027] The presence of the tab 12 offers a greater retention of the cup cover with respect
to the cap.
[0028] Figures 7-8 show a second embodiment of the cap with cap cover according to the invention.
[0029] In this second embodiment the cap cover 6 is provided with a set of grooves 21 defined
on its inner surface, the grooves being arranged parallel to the axis of the cap cover.
[0030] The body 2 of the cap 1 is provided externally with a set of grooves 20 arranged
in the direction of the longitudinal extension of the cap body 2, thus with the grooves
20 parallel to the axis of the cap.
[0031] The grooves 20 are notches, the depth and number of which can vary according to the
requirements.
[0032] The grooves 20 are adapted to couple to the corresponding set of grooves 21 defined
at the inner surface of the cap cover 6.
[0033] In particular, the set of grooves 21 of the cap cover 6 can be defined at at least
one portion of the inner surface of the cap cover or on all of the inner circumferential
surface of the cap cover 6.
[0034] The set of grooves 20 combined with the set of grooves 21 allows to orient and align
the cap cover 6 without any forcing, in a precise manner, with the cap body 2, before
the coupling among the retention means 7, the rim 8 and the tab 12 described above.
[0035] In practice it has been found that the cap with cap cover according to the present
invention fully achieves the intended aim and objects, since it allows to be screwed
usually on a threaded bottle and to be protected by the cap cover that is coupled
to the below cap by means of the flexible wings cited above, therefore without the
use of further threads and above all with a simple and effective action by the user.
[0036] The cap with cap cover thus conceived is susceptible of numerous modifications and
variations, all of which are within the scope of the appended claims. All the details
may further be replaced with other technically equivalent elements.
[0037] In practice, the materials used, as well as the contingent shapes and dimensions,
may be any according to requirements and to state of the art.
[0038] Where technical features mentioned in any claim are followed by numeral reference
and/or signs, those numeral reference and/or signs have been included for the sole
purpose of increasing the intelligibility of the claims and accordingly such numeral
reference and/or signs do not have any limiting effect on the interpretation of each
element identified by way of example by such numeral reference and/or signs.
