BRA CUP HAVING AN ENHANCING EFFECT
TECHNICAL FIELD
The invention relates to a lightweight bra cup for giving the bust an
enhancing effect
called "push-up" effect.
BACKGROUND
It is known many cups which are designed for making a bra with a "push-up"
effect,
which allows visually increasing the size of the bust by one size or more.
Document FR-A-2972905 describes and represents a bra cup structure which
includes an
external layer and an internal layer stuck together enclosing therebetween a
pocket containing a
malleable material, in silicone gel according to this document.
The pocket is constituted of two fine polymeric films which are sealed
together in a
permeable manner in order to imprison the silicone gel.
Although this type of cup fulfills its role of giving the bust an enhancing
effect, the
presence of the filling material of the pocket has in particular, the drawback
of adding an
additional weight to the bra which may cause discomfort.
BRIEF SUMMARY
The purpose of the invention is in particular to overcome this issue by
proposing a
lightened cup allowing a "push-up" effect.
In addition, the purpose of the invention is to propose a cup with a
simplified design
which does not require an added pocket for retaining a filling material.
To this end, the invention proposes a bra cup which includes an external shell
forming a
recess of globally hemispherical shape and which is delimited by a peripheral
edge, characterized
in that the cup includes at least one internal skin forming a lining which is
fixed on the peripheral
edge of the cup and which partially covers the recess formed by the external
shell, by delimiting
a space with the external shell, and in that the internal skin is suitable for
being tensioned when
the cup is placed on a bust.

Such a design allows the internal skin to push the bust towards the
décolletage in order to
cause an enhancing effect, without adding a cushion.
According to another feature, the internal skin substantially covers a lateral
half of the
cup.
This feature allows guiding the bust towards the décolletage part of the cup.
In addition, the internal skin includes a lateral edge which extends through
the cup from
an upper section of the peripheral edge of the cup, to a lower section of the
peripheral edge of the
cup, the internal skin being arranged in such a manner as to push the bust
towards a décolletage
part of the cup.
Furtherniore, the internal skin is fixed on the peripheral edge of the cup by
means of
scams.
According to another aspect, the internal skin is made in expansible fabric of
tulle type.
This type of material is breathable, comfortable and expansible.
In addition, the internal skin is capable of being elastically expanded
according to a range
between fifty percent and one hundred and fifty percent with respect to an
initial rest state.
According to another aspect, the external shell is made in thermoformed
polyurethane
foam.
In addition, the external shell has a thickness ranging between 8 and 15
millimeters
before thermoforming.
Finally, the external shell has a thickness ranging between 3 and 6
millimeters after
thermoforming.
The invention also relates to a bra including the aforementioned pair of cups.

FIG. 2 is a perspective detailed view, which illustrates the space delimited
between the
external shell and the internal skin of the first left cup of FIG. 1;
FIG. 3 is a sectional view according to line 3-3 of FIG. 1, which illustrates
the profile of
the first left cup of FIG. 1.
DETAILED DESCRIPTION
In the description and claims, the expressions "upper" and "lower" will be
used in a non
limiting manner in reference to the upper part and the lower part respectively
of FIG. 1.
In addition, in order to clarify the description and claims, the longitudinal,
vertical and
transversal terminology will be used in a non limiting manner in reference to
the trihedral L, V,
T indicated on FIGS. 1 and 2.
It has been represented on FIG. 1 a bra 10 which includes a first left cup 12
and a second
right cup 14 which are transversally aligned and which are connected by a
central supporting
component 16.
In addition, the bra 10 is equipped with a dorsal fixing strip 18 which is
formed by a first
part 20 connected on the first cup 12 and by a second part 22 connected on the
second cup 14.
The fixing strip 18 is provided with a fastening means, which includes a
staple 26
mounted on the first part 20 of the fixing strip 18 and a series of additional
notches (not
represented) mounted on the second part 22 of the fixing strip 18.
In a complementary manner, the bra 10 includes a pair of straps 28 allowing
the bra 10 to
be worn on the shoulders of the person wearing it.
Each cup 12, 14 is delimited by a peripheral edge 32 which includes an upper
section 34
forming décolletage and a lower section 36 housing an added framework, such as
a metallic
framework.
In addition, each cup 12, 14 includes an external shell 38 forming a recess 40
of globally
hemispherical shape, cambered towards the front along a longitudinal
direction, as it can be seen
schematically illustrated by the dots and arrow of FIG. 2.
The first left cup 12 and the second right cup 14 being similar and arranged
symmetrically in order to form the bra 10, only the first left cup 12, called
"cup" in the rest of the
description, will be described in detail.

The cup 12 includes an internal skin 42 forming a lining which is fixed on the
peripheral
edge 32 delimiting the cup 12, by means of scams for example.
In reference to FIGS. 2 and 3, the internal skin 42 partially covers the
recess 40 formed
by the external shell 38, by delimiting an empty space with the external shell
38 which is
illustrated by the arrow of FIG. 2.
The internal skin 42 substantially covers a lateral half of the cup 12, facing
the
décolletage part of the cup 12, in such a manner that the internal skin 42
pushes the bust towards
the décolletage, that is to say towards the central part and towards the top
of the bra 10.
More particularly, the internal skin 34 includes a lateral edge 44 which
expands across
the cup 12 from the upper section 34, to the lower section 36 of the
peripheral edge 32 of the cup
12.
The internal skin 34, in a rest position in which the cup 12 is not worn, is
more or less
tensed according to the required enhancing effect.
On the other hand, the internal skin 34, in an active position in which the
cup is worn by
a person, is tensioned in such a manner as to push the bust towards a
décolletage part of the cup
12.
To this end, the internal skin 34 is capable of being elastically expanded
according to a
range between fifty percent and one hundred and fifty percent with respect to
an initial state of
rest, for example.
According to another aspect, the internal skin 34 is made in an expansible
fabric of tulle
type, for example in fabric known by the name of "powernet" which designates a
nervous fabric
made from elastane fibers and nylon fibers.
In addition, the external shell 38 is made in thermoformed polyurethane foam.
The external shell 38 is designed so as to hardly or not become deformed when
the cup
12 is worn by a person.
To this end, as a reference, the external shell 38 has a thickness ranging
between 8 and 15
millimeters before thermoforming, and a thickness ranging between 3 and 6
millimeters after
thermoforming.

= CA 2885313 2017-05-10
According to a non represented variant, the cup 12 includes a plurality of
internal skins
which cover each other, in totality or partially, in such a manner as to play
on the expansibility
and elastic resistance of the assembly constituted by the internal skins.
