Description
SUMMARY OF THE INVENTION
This invention relates to a new type of bottle which is
particularly useful for holding certain cosmetic products.
Glass bottles are of course already well known and particularly
colored glass bottles covered by a mass of transparent glass. Such
bottles are generally made by highly skilled workmen, because the
production thereof is rather difficult. In particular, it is very
difficult to form a glass coating about a bottle having a neck
adapted to receive a cap closing the bottle. Moreover, the
technique of making these glass coated bottles does not permit the
formation of indicia in relief or engraved on the inner bottle.
Finally the cost of such glass coating is high and the fact that
they are hand made makes it impossible to insure perfect
consistency in the coating properties and the final appearance of
the bottle.
The present invention makes it possible to reduce the said
disadvantages by providing on the outside of a bottle of a
conventional type having indicia on its lateral walls and a neck
adapted to receive a stopper, a coating of a transparent synthetic
plastic material, which coating has certain properties which
improve the resistance of the complete bottle to shock and insure a
product having an attractive appearance.
It is the object of the present invention to provide a new article
of manufacture which consists of a coated bottle, essentially
characterized by the fact that it comprises, on the one hand, an
inner container having a neck, which container is generally ovoid
in shape and may carry indicia on its lateral walls which are in
relief or engraved, and on the other hand a coating around the
ovoid container made of a transparent synthetic resin, the outer
surface of said coating being an ovoid surface which encircles the
first ovoid surface and is pierced by the neck of the said
container. The thickness of the coating is at a minimum at the neck
and progressively increases to a maximum, moving away from the
neck.
In a preferred embodiment of the invention, the minimum thickness
of the coating in the zone of the neck of the container is about
3-6 mm., the maximum thickness of the coating falls within a range
from about 8 mm. to about 25 mm., the lower part of the coated
bottle has the thickest coating, the inner container has no sharp
corners except for the indicia which may be applied thereto, the
outer surface of the coating is smooth and rounded, and the coating
increases progressively in thickness from the zone of minimum
thickness to that of maximum thickness.
The inner container may advantageously consist of a glass bottle
several mm thick. Good results have been obtained with a colored
glass bottle having the shape of a solid of revolution, the axis of
revolution being the axis of the neck of the container. In this
case, the coating has preferably an external surface of revolution
about the axis of the neck of the inner container. It is clear that
the inner container may consist of a colorless glass and that the
transparent coating resin may be colored. A polyester type resin
may advantageously be selected as a coating material.
It has been found that a particularly attractive appearance is
obtained when the ratio between the maximum thickness of the
coating and the average diameter of the inner container is between
0.3 and 0.7.
It should be noted that the neck of the container may cooperate
with a conventional cap or with a cap made of a coated material,
which stopper may then have the same characteristics as the main
container. In particular the cap may be made of a colored material,
the coating being transparent and increasing progressively in
thickness from the zone at which the cap contacts the neck of the
bottle to the zone most remote therefrom. In this case, the
dimensions of the coating with respect to those of the cap should
lie within the range of ratios previously indicated. It is also
preferable to avoid any sharp corners on the cap which may take the
form of an ovoid inner part within a coating having a
correspondingly ovoid external surface.
It is consequently also the object of the present invention to
provide, as a new article of manufacture, a coated bottle as
hereinbefore defined in combination with a cap which fits onto the
neck of the inner container and is essentially characterized by the
fact that this cap comprises an inner part defining a opening which
cooperates with the neck of the aforesaid bottle, which inner part
has a generally ovoid shape and which may carry indicia in relief
or engraved on its lateral surface and, on the other hand, a
coating positioned around said ovoid part and made of a transparent
synthetic resin, the outer surface of said coating being an ovoid
surface which encircles the inner ovoid part, and the coating being
thinnest at the area of contact between the stopper and the bottle
neck.
In a preferred embodiment of the invention, the minimum thickness
of the coating of the cap, in the area in which it fits onto the
bottle with which it is associated, falls within a range of from
2-4 mm. The maximum thickness of said coating lies within a range
of 10-15 mm. The zone of maximum thickness of the coating of the
stopper is farthest from the zone at which the stopper contacts the
bottle with which it is associated. The inner part of the stopper
has no sharp corners except for the indicia which it carries. The
outer surface of the coating of the cap is smooth and rounded. Any
of the molding methods in conventional use may be used for
manufacturing the product according to the invention, or the inner
container may be included by molding within a block of the coating
material and this block machined to bring its outer surface to the
dimensions desired. In order that the object of the invention may
be better understood, one embodiment thereof will now be described,
purely by way of illustration and example, with reference to the
accompanying drawings in which:
FIG. 1 is a sectional view through a bottle according to the
invention, equipped with a coated cap; and
FIG. 2 is an elevational view showing the outer appearance of the
bottle of FIG. 1, the coated stopper being separated from the
bottle, and shown in perspective.
Referring now to the drawings it will be seen that reference
numeral 1 indicates the inner container of the bottle according to
the invention. The container 1 is a solid of revolution about the
axis of its neck 2. The neck 2 is threaded to cooperate with a
matingly threaded stopper. The container 1 is made of colored glass
having a thickness of 2-3 mm. It carries in the central part of its
lateral wall indicia 3 in relief. The zone 4 of the container 1
which is opposite the neck 2 is nearly flat.
Around the container 1 is a transparent polyester coating 5. The
outer surface of the coating 5 is a surface of revolution having
the same axis of rotation as the container 1. At the neck 2, the
thickness of the coating is about 3 mm. In zone 4 the thickness of
the coating is about 15 mm. The thickness of the coating 5
increases progressively from the area of the neck to said area of
maximum thickness. In the area of maximum thickness the coating 5
forms a base 6 perpendicular to the axis of the external surface of
the bottle.
The cap associated with the bottle which has just been described
comprises an inner part 7 made of a colored glass. This part 7 has
a central threaded recess 8. The threading of the recess 8 mates
with the threads carried by the neck 2.
The inner part 7 has a thickness which ranges from 2 to 5 mm at
various points. The part 7 and the recess 8 are solids of
revolution about an axis which coincides with the axis of the neck
2 when the cap is mounted on the container. The part 7 is encircled
by a transparent polyester coating 9. The outer surface of the
coating 9 is a surface of revolution having the same axis of that
of the bottle 7. In the zone of the cap which comes into contact
with the coating 5 of the bottle stopper, the coating 9 has a
thickness of about 3 mm. In the zone opposite the zone of contact
between the cap and the bottle, the coating 9 has a thickness of
about 12 mm. The thickness of the coating 9 increases progressively
from the zone of contact with the bottle stopper toward the zone of
maximum thickness.
It has been found that the bottle which has just been described has
an attractive appearance to the user. The use of a coating of
synthetic resin makes it possible to provide the indicia 3, which
is impossible with a glass coating. Moreover, the bottle and its
cap have a substantial thickness of synthetic resin on the outside
which greatly improves the resistance of the bottle to shocks.
It will of course be appreciated that the embodiment which has just
been described has been given purely by way of illustration and
example, and may be modified as to detail without thereby departing
from the basic principles of the invention.
