Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application claims priority under 35 U.S.C. 119(a) to
French Patent Application No. 1757326, filed Jul. 31, 2017.
BACKGROUND OF THE INVENTION
Field of the Invention
[0002] The invention relates to a case for cosmetic products. Such
cases usually include a base for receiving cosmetic products and a
cover to close or open the case. Thus, when the cover is in an open
position, the user has access to the base.
Description of the Related Art
[0003] Generally, cases for cosmetic products include a housing
configured to receive the cosmetic product and a cover. The cover
is conventionally closed by clipping or screwing. In the closed
position, the cover protects the cosmetic product and the opening
thereof enables the user to access the cosmetic product which is
located in the housing.
[0004] To obtain a sufficient sealing against impurities and fluids
between the inner and outer environments of the case, it is
recommended to use a seal, in particular if this relates to a
cosmetic product including a volatile and/or damp composition.
Generally, the seal is arranged between the base and the cover and
it undergoes flattening when the case is in the closed
position.
[0005] Generally, the locking is done by a locking system, such as
a pushbutton, in one single point placed on the front of the case.
The pressure exerted on the seal is thus not consistent over the
whole surface of the seal, in particular behind the case. The
sealing is thus not sufficiently effective and the cosmetic product
risks being damaged quickly or pouring out.
[0006] In addition, in this type of case, the presence of the seal
creates additional pressure, and locking/unlocking can thus be more
difficult to achieve.
[0007] In the case, for example, of cases closed by screwing, when
the case goes from the open position to the closed position and
vice versa, this in particular leads to friction on the seal. After
several openings/closings, a premature wear on the seal is
observed, the sealing is damaged and the case is no longer
sufficiently sealed. The cosmetic product thus risks accelerated
ageing. In addition, it is not possible to reuse the product, once
the cosmetic product is finished, as the sealing is no longer
effective.
[0008] Therefore, there is a need for a case for cosmetic products
enabling to resolve the preceding disadvantages and which has a
simple design that is easy to use.
BRIEF SUMMARY OF THE INVENTION
[0009] For this purpose, the present invention proposes a cosmetic
case including a base, a cover, a seal and a closing/opening
means.
[0010] The base and the cover are hinged against each other via a
pivot connection. The case is capable of occupying two separate
positions, a closed position wherein the cover is held in position
on the base by the closing/opening means and an open position
wherein the cover is free to pivot with respect to the base.
[0011] The closing/opening means includes: [0012] an additional
part which is in slide connection or in pivot connection with the
cover, [0013] a plurality of locking means connected to the
additional part--respectively to the base, the locking means being
designed to each cooperate with a housing provided in/on the
base--respectively in/on the additional part, the plurality of
locking means forming, with the housings, a multipoint locking.
[0014] The seal is provided on the surface of the
base--respectively of the cover--so as to undergo flattening by the
cover--respectively by the base--when the case is in the closed
position.
[0015] The multipoint locking applies sufficient pressure on the
seal when the case is in the closed position such that the sealing
against impurities and fluids between the inner and outer
environments of the case, in the closed position, is total under
the normal temperature and pressure conditions (NTPC). In other
words, the multipoint locking is configured to apply a pressure on
the seal such that, in the closed position, the case is closed so
as it is sealed, that is to say, with a sealing against the
impurities and fluids between the inner and outer environments of
the case which is total under the normal temperature and pressure
conditions (NTPC).
[0016] Contrary to the conventional case, the case according to the
invention includes an additional part, mobile with respect to the
cover.
[0017] On the one hand, this additional part enables the use of a
multipoint locking. Such a multipoint locking enables a
distribution of the pressure exerted on the seal. The sealing is
thus effective and sufficient at any point of the seal, both for
dust particles and for a liquid.
[0018] On the other hand, the presence of the additional part
enables an opening of the case by applying a more significant
force, thus a seal can be added without this complicating the
locking and unlocking of the case.
[0019] Moreover, the presence of the additional part avoids having
friction between the cover and the base. Thus, the passage from the
closed position to the open position of the case and vice versa,
does not lead to premature wear of the seal. The cosmetic product
does not therefore risk being damaged prematurely.
[0020] Moreover, once the cosmetic product is finished, the sealing
is still effective and the case remains operational to receive an
amount of additional cosmetic product, to be refilled with cosmetic
product.
[0021] According to different embodiments of the invention, which
can be taken together or separately: [0022] the actuation of the
closing/opening means is done by the moving of the additional part
with respect to the cover so as to engage/disengage the locking
means of their respective housing, such that the passage from the
open position to the closed position of the case, and conversely,
does not provoke any friction on the seal, [0023] the connection
between the additional part and the cover is ensured by a
cooperation of technical forms present, on the one hand, over the
outer periphery of the cover, and on the other hand, over an inner
circumference of the additional part, [0024] the locking means and
their respective housing being regularly distributed over the outer
periphery of the cover and/or over the inner circumference of the
additional part, [0025] the seal is presented in the form of a
material strand, [0026] the seal is returned to the surface of the
base--conversely to the surface of the cover, [0027] the seal is
held in position by surface gluing, [0028] the seal is over-molded
with the base--conversely with the cover, [0029] the locking means
are hooks, [0030] the hooks have a technical form including a slope
intended to facilitate the insertion of the hooks in their
respective housing during the passage from the open position to the
closed position of the case, [0031] the additional part is designed
to make it inaccessible to touch almost all of the cover for an
exterior user when the case is in the closed position, the part of
the cover enabling it to pivot with respect to the base when the
case is in the open position, referred to as hinging, being the
only part of the cover accessible to touch for an exterior user
when the case is in the closed position, [0032] the additional part
is designed so as to surround the whole cover, except for the
hinging, [0033] the case further includes a means for assisting the
opening of the case, [0034] the means for assisting the opening of
the case is intended to automatically remove the cover from the
base during the passage of the case from the closed position to the
open position, this without the exterior user having to intervene,
[0035] the assistance means are presented in the form of at least
one material beading protruding from the base--respectively from
the cover, in the direction of the cover--respectively from the
base, next to the hinging, [0036] the seal serves as a means for
assisting the opening of the case, [0037] the base is intended to
receive a cosmetic product, in particular a cosmetic product
including a volatile and/or damp composition, [0038] the base is
intended to receive a cosmetic product applicator, [0039] the cover
is capable of receiving a mirror of the pocket mirror type.
[0040] Additional aspects of the invention will be set forth in
part in the description which follows, and in part will be obvious
from the description, or may be learned by practice of the
invention. The aspects of the invention will be realized and
attained by means of the elements and combinations particularly
pointed out in the appended claims. It is to be understood that
both the foregoing general description and the following detailed
description are exemplary and explanatory only and are not
restrictive of the invention, as claimed.

DETAILED DESCRIPTION OF THE INVENTION
[0057] The invention relates to a case 1 for cosmetic products
including: [0058] a base 3, [0059] a cover 5, and [0060] a
closing/opening means 7.
[0061] In the description which will follow, the trihedral X, Y, Z
is referred to, represented in different figures. The axis X is the
main direction of longitudinal extension of the case 1, referred to
as main direction, the axis Z is an axis orthogonal to the axis X
and parallel to the plane defined by a bottom of the case 1 and
parallel to the axis of rotation of the cover 5 and finally the
axis Y is an axis orthogonal to the axes X and Z.
[0062] In a non-limitative manner, the terms "higher" and "high" or
"lower" and "low" are used in reference to the axis X.
[0063] The terms "interior" and "inner" are used with respect to
the case 1 to name an element directed towards the centre of the
case 1 or situated in the case 1 and the terms "exterior" and
"outer" are used with respect to the case 1 to name an element
directed towards the exterior of the case 1 or situated outside of
the case 1.
[0064] The terms "front" and "rear" are used in reference to the
axis Y.
[0065] The base 3 and the cover 5 are hinged with respect to one
another via a pivot connection.
[0066] The case 1 is capable of occupying at least two separate
positions: [0067] a closed position (that can be seen in FIGS. 2
and 8) wherein the cover 5 is held in position on the base 3 by the
closing/opening means 7, and [0068] an open position (that can be
seen in FIGS. 4, 5, 7 and 10) wherein the cover 5 is free to pivot
with respect to the base 3.
[0069] The pivot connection is obtained by a part of the cover 5,
referred to as hinging 9, enabling it to pivot with respect to the
base 3 when the case 1 is in the open position.
[0070] The closing/opening means 7 includes: [0071] an additional
part 11 which is in slide connection or in pivot connection with
the cover 5, and [0072] one or more locking means 13 connected to
the additional part 11--respectively from the base 3.
[0073] The locking means 13 are designed to each cooperate with a
housing 15 provided in/on the base 3--respectively in/on the
additional part 11. The plurality of locking means 13 form, with
the housings 15, a multipoint locking.
[0074] Each instance of cooperation between one of the locking
means 13 and the housing 15, which is connected to it, determines
one of the locking points forming the multipoint locking.
[0075] Thus, the case 1 according to the invention has two main
embodiments:
[0076] a first main embodiment represented in FIGS. 1 to 5d wherein
the additional part 11 is in slide connection with the cover 5,
[0077] a second main embodiment represented in FIGS. 6 to 12
wherein the additional part 11 is in pivot connection with the
cover 5.
[0078] Each one of the two main embodiments can have variants of
embodiments.
[0079] Subsequently, some of these variants will be defined.
[0080] Moreover, the cosmetic case 1 includes a seal 21.
[0081] The seal 21 is provided on the surface of the base
3--respectively of the cover 5--so as to undergo flattening by the
cover 5--respectively by the base 3--when the case 1 is in the
closed position.
[0082] The multipoint locking is configured to apply sufficient
pressure on the seal 21 when the case 1 is in the closed position
such that the sealing against impurities and fluids between the
inner and outer environments of the case 1, is total under the
normal temperature and pressure conditions (NTPC), that is to say,
a temperature of 0.degree. C. and a pressure of 1 atm.
[0083] "Impurities" mainly means solid impurities such as
particles, dust, or cosmetic product powder.
[0084] "Fluid" means a liquid or a gas coming from the cosmetic
product or from the exterior of the case. This can be, for example,
a solvent, a volatile product, the cosmetic product itself, water,
oxygen, etc.
[0085] The seal 21 can be returned to the surface of the base
3--conversely to the surface of the cover 5, held in position by
surface gluing or over-molded with the base 3--conversely with the
cover 5.
[0086] In certain variants, the seal 21 can be a means for
assisting the opening of the case 1.
[0087] Advantageously, the seal 21 is made of elastomer, such as
rubber, silicone, expanded polyethylene, such as Tresylene.RTM. or
any other material enabling to guarantee the sealing of the
case.
[0088] Advantageously, the actuation of the closing/opening means 7
is done by moving of the additional part 11 with respect to the
cover 5, so as to engage/disengage the locking means 13 of their
respective housing 15.
[0089] Thus, the passage from the open position to the closed
position of the case 1, and conversely, can be done by applying a
significant force if this is necessary. The presence of a seal 21
is therefore possible without impeding the engagement/disengagement
of the locking means 13. In addition, this system does not provoke
any friction on the seal 21.
[0090] Preferably, the additional part 11 is designed to make
almost all of the cover 5 inaccessible to the touch of an exterior
user when the case 1 is in the closed position, the hinging 9 being
the only part of the cover 5 accessible to touch for an exterior
user when the case 1 is in the closed position. In other words, the
additional part 11 is designed so as to surround all of the cover
5, except for the hinging 9, which is what "almost all of the cover
5" means.
[0091] Thus, a case 1 is obtained wherein almost only the base 3
and the additional part 11 are accessible. This provides a refined
and pleasant aesthetic appearance.
[0092] In addition, by preventing access from the cover 5 to the
user in the closed position of the case 1, the user can easily move
the additional part 11 with respect to the cover 5, without the
movement being impeded by inadvertently holding the cover 5, for
example.
[0093] This is particularly advantageous in the case of thin cases
for which handling and moving only the additional part 11 can be
difficult if the cover 5 is accessible.
[0094] In other words, the case 1 can be opened by pushing on both
the upper surface and on the edge of the additional part 11, or on
the layer thereof. Handling is thus easier and the movement is
facilitated. The fingers of the user risk less sliding with respect
to a system where the opening is achieved by sliding, by pressing
only on the upper surface of a part.
[0095] Moreover, using an additional part 11 for the
locking/unlocking of the case 1 and for placing this part 11 such
that the cover 5 is almost inaccessible to the user enables to not
obstruct the inner face of the cover 5 and to arrange a mirror
there, for example.
[0096] Preferably, the locking points determined by the locking
means 13 are evenly distributed over the inner circumference of the
additional part 11--respectively over the periphery of the base
3--each being intended to cooperate with a dedicated housing
15.
[0097] The multipoint locking of the case 1 includes at least two
locking points, preferably four locking points or more.
[0098] Advantageously, the number of locking points is an even
number.
[0099] Preferably, the housings 15 are provided in the base 3 or
the additional part 11 and are evenly distributed.
[0100] Each one of the housings 15 is, for example, a cavity, such
as a notch, designed in the base 3 or the additional part 11 so as
to retain the corresponding locking means 13 and holding the case 1
in the closed position.
[0101] The housings 15 can also be provided on the base 3 or the
additional part 11. Each one of the housings 15 is thus, for
example, in the form of an embossed zone configured to receive the
corresponding locking means 13 and retaining it engaged to hold the
case 1 in the closed position.
[0102] "Embossed" means a swelling, an element protruding from the
base 3 or from the additional part 11, such as an embossed mold, a
returned element (over-molded or glued) wherein a housing 15 is
formed to receive the locking means 13.
[0103] The case 1 can also include a means for assisting the
opening of the case 1. The assistance means can be presented in the
form of at least one material beading (not represented) protruding
from the base 3--respectively from the cover 5, in the direction of
the cover 5--respectively of the base 3, close to the hinging
9.
[0104] The means for assisting the opening of the case 1 is
intended to remove the cover 5 from the base 3 during the passage
of the case 1 from the closed position to the open position, while
maintaining a preopening of a few degrees, for example, a
preopening of between 0.5 and 5.degree., preferably 3.degree..
[0105] Advantageously, the seal 21 can play the role of means for
assisting the opening of the case 1.
[0106] In the first embodiment represented in FIGS. 1 to 5d, the
case 1 is of parallelepiped shape, and more specifically, of square
shape. It includes a rear side AR on which is positioned the pivot
connection, a front side AV opposite the rear side AR and two
lateral sides extending from the rear side AR towards the front
side AV. A rectangular shape or any other shape, for example,
mainly circular, could be considered.
[0107] In certain variants, the front side AV can include a
gripping zone 22 that can be seen in FIG. 5c for example, so as to
facilitate the opening of the cover 5.
[0108] In this first embodiment, the additional part 11 is in slide
connection with the cover 5.
[0109] The slide connection between the additional part 11 and the
cover 5 is ensured by the cooperation between the technical shapes
present, on the one hand, over the outer periphery of the cover 5,
and on the other hand, over an inner circumference of the
additional part 11.
[0110] In this embodiment, each one of the lateral sides of the
cover 5 includes two ridges 25 configured to cooperate with a
groove 27 extending over the whole length of each one of the
lateral sides of the additional part 11 (FIGS. 5b and 5c). In other
words, the grooves 27 of the additional part 11 serve as slides to
the ridges 25 of the cover 5, the additional part 11 being able to
thus move in translation along the axis Y with respect to the cover
5.
[0111] Preferably, the locking means 13 are hooks.
[0112] This translation movement enables the actuation of the
closing/opening means 7 and therefore engages/disengages the hooks
13 from their corresponding housing 15. To engage/disengage the
hook 13 from the housing 15, the additional part moves in
translation with respect to the base.
[0113] The cover 5 can also include at least one recess 28 so as to
make the part of the cover 5 which supports the ridges 25 flexible
(FIGS. 1 and 5d). This flexibility facilitates the assembly of the
cover 5 in the additional part 11, in particular the assembly of
the ridges 25 inside the grooves 27.
[0114] Preferably, the recess(es) 28 cross(es) and extend(s) over
the part(s) of the cover 5 adjacent to the ridges 25.
[0115] In the variant of the embodiment represented in FIG. 5d, the
cover includes four recesses 28. In other words, these recesses 28
give elasticity to the walls supporting the ridges 25 so as to
facilitate the insertion, in particular by interlocking, preferably
by clipping, of the part of the cover 5 inside the additional part
11.
[0116] In this embodiment, the hinging 9 is here situated on the
rear side AR of the cover 5. It is a material extension, here in
the form of a rectangular parallelepiped 9 being housed, during the
assembly of the cover 5 to the base 3, in a housing 29 arranged
behind the base 3 and formed between two extensions 30 of the base
3 situated towards the exterior of the case 1.
[0117] The material extension or hinging 9 is connected to the base
3 by the intermediary of at least one spindle 31 connecting the
base 3 and the hinging 9 of the cover 5. Here, the hinging 9
includes two holes 33a situated on either side of the hinging 9 and
the spindle corresponds to two pins 31.
[0118] Each one of the pins 31 has a first end inserted into one of
the holes 33a of the hinging 9 and a second end inserted into a
hole 33b formed on the rear side AR of the base 3 at the level of
each one of the extensions 30. The pins 31 determine the axis of
rotation of the cover 5, which is parallel to the axis Z. Any other
means enabling to fulfil this function will be included in the
invention.
[0119] In an embodiment not represented, it can also be devised
that the only part of the cover 5 accessible to touch by an
exterior user when the case 1 is in the closed position, referred
to as hinging 9, is made of two material extensions of the cover 5
situated towards the exterior of the case 1 on the rear side AR and
forming a housing wherein an extension of the base 3 is placed, for
example, in the form of a rectangular parallelepiped, or a
cylinder, each one of the extensions of the cover 5 and of the base
3 being bored to make at least one pin 31 pass through to make the
pivot connection between the base 3 and the cover 5. In other
words, it is a system opposite to the one represented here.
[0120] According to the invention, the case 1 includes a seal 21
provided, here, on the inner surface of the cover 5 so as to
undergo flattening by the base 3 when the case 1 is in the closed
position.
[0121] In this embodiment, the seal 21 is a material strand
inserted into a groove 23 formed over the whole periphery of the
inner surface of the cover 5 so as to obtain a sealing over the
whole circumference of the case 1.
[0122] In this embodiment, the locking means are four hooks 13
distributed two-by-two over the lateral sides of the additional
part 11 cooperating with four housings 15 distributed two-by-two
over the lateral sides of the base 3.
[0123] The housings 15 are L-shaped and include an inlet 15b to
enable the engagement of the corresponding hook 13 and a locking
zone 15c to enable the locking of the hook after translation
movement of the additional part 11.
[0124] Advantageously, the housings 15 have a protrusion 15a
configured to form the locking zone 15c and to retain the hook 13
and hold the case 1 in the closed position (FIGS. 1, 3 and 5a).
[0125] In this embodiment, the hooks 13 are integrally formed with
the additional part 11. Preferably, the hooks 13 are rigid to be
able, in particular, to contain the pressure of the seal.
[0126] They can also have a technical form including a slope so as
to amplify the closing force during the locking of the case 1 and
to facilitate the entry of each one of the hooks 13 into the
corresponding housing 15 during the passage from the open position
to the closed position of the case 1 and the locking thereof. The
term "rigid hook" means an element that resists to pressure, and
that does not fold or deform under pressure.
[0127] In other variants of embodiments not represented, it can
also be considered that the locking means 13 are connected to the
base 3 and that the housings 15 are provided in the additional part
11.
[0128] It can also be considered that the housings 15 are designed
on the base 3 or the additional part 11.
[0129] In this embodiment, the means for assisting the opening of
the case 1 is the seal 21 provided on the surface of the cover 5.
The seal is compressed when the case 1 is closed and it loosens
when the locking means 13 are released, thus enabling a preopening
of the case 1 by a few degrees, preferably 3.degree. (FIG. 3).
[0130] The opening mechanism will now be described in reference to
FIGS. 2 to 4.
[0131] Initially, the user releases the hooks 13 from the
additional part 11 inserted in their housing 15 provided on the
base 3 by a translation movement along the axis Y of the additional
part 11 with respect to the cover 5 and with respect to the base 3.
In other words, in the closed position of the case 1, the hooks 13
are blocked at the level of the locking zone 15c from their housing
15 by the protrusion 15a.
[0132] During the translation movement of the additional part, the
hooks 13 are located in the alignment of the inlet 15b, as can be
seen in FIG. 3. Thus, nothing else retains the case in the closed
position, the hooks 13 are thus released and the case 1 opens as
can be seen in FIG. 3.
[0133] The opening of the cover 5 is particularly facilitated by
the presence of the seal 21 which loosens and ensures a preopening
of the case 1 by around 3.degree.. The user then finishes the
opening of the case 1 by pivoting the cover 5 assembled to the
additional part 11 until the open position illustrated in FIG.
4.
[0134] In the second embodiment represented in FIGS. 6 to 12, the
cover 5, is of a circular shape and the additional part 11 has a
mainly parallelepiped shape.
[0135] The case 1 has a rear part AR and a front part AV opposite
the rear part AR. As for the first embodiment, a gripping zone (not
represented) could be considered on the front part AV of the case
1.
[0136] Likewise, a circular shape could also be considered for the
additional part 11.
[0137] In this second embodiment, the additional part 11 is in
pivot connection with the cover 5.
[0138] As for the slide connection of the first embodiment, the
pivot connection between the additional part 11 and the cover 5 is
ensured by a cooperation of technical forms present, on the one
hand, over the outer periphery of the cover 5, and on the other
hand, over the inner circumference of the additional part 11.
[0139] In this embodiment, the inner circumference of the
additional part 11 includes ridges 25, here three, evenly and
angularly distributed and configured to cooperate with the grooves
27, here three, extending over the outer periphery of the cover 5
and evenly and angularly distributed (FIGS. 11 and 12).
[0140] The grooves 27 of the outer periphery of the cover 5 serve
as a guiding path for the ridges 25 of the inner circumference of
the additional part 11. The additional part 11 can thus be moved
with respect to the cover 5 according to a rotation movement of
axis parallel to the axis X. This rotation movement enables the
actuation of the closing/opening means 7 and to engage/disengage
the hook 13 from the housing 15.
[0141] The system enabling the pivot connection between the cover 5
and the base 3 is similar to that of the first embodiment.
[0142] The hinging 9 of the cover 5 is connected to the base 3 by
means of two pins 31 inserted into the holes 33a, 33b of the
hinging 9 and of the base 3. The pins 31 determine the axis of
rotation of the cover 5, which is parallel to the axis Z.
[0143] In this second embodiment, the case 1 also includes a seal
21 provided on the inner surface of the cover 5 so as to undergo
flattening by the base 3 when the case 1 is in the closed
position.
[0144] Preferably, the seal 21 is in the form of a material strand
inserted into a groove 23 formed over the whole periphery of the
inner surface of the cover so as to obtain a sealing over the whole
circumference of the case 1.
[0145] In this embodiment, the locking means are also four hooks
13. The hooks 13 are integrally formed with the base 3 and are
regularly angularly distributed over it. The hooks 13 cooperate
with four housings 15 regularly angularly distributed in the
additional part 11.
[0146] Preferably, the hooks 13 are rigid and have a technical form
including a slope so as to be able to contain the pressure of the
seal 21 and amplify the closing force during the locking of the
case 1.
[0147] In this embodiment, the cover 5 advantageously includes four
slots 24 evenly and angularly distributed to enable the passage of
the hooks 13 to their corresponding housing 15 provided in the
additional part 11, and/or the releasing of the hooks 13 from their
housing 15.
[0148] After rotation of the additional part 11 with respect to the
cover 5, the hooks 13 are blocked by the cover 5 and the case 1 is
held in the closed position.
[0149] As in the first embodiment, the means for assisting the
opening of the case 1 is, here, the seal 21 provided on the surface
of the cover 5. The seal 21 is compressed when the case 1 is closed
and it loosens when the locking means 13 are released, thus
enabling a preopening of the case 1 by a few degrees, preferably
3.degree. (FIG. 9).
[0150] The opening mechanism will now be defined in reference to
FIGS. 8 to 10.
[0151] The opening mechanism is similar to that of the first
embodiment, only the type of movement of the additional part 11
with respect to the cover 5 differs. Indeed, in the first
embodiment, the movement is a translation movement along the axis Y
whereas in this second embodiment, the additional part 11 makes a
rotation movement with respect to the cover 5.
[0152] Initially, the user releases the hooks 13 from the base 3
inserted in their corresponding housing 15 provided on the
additional part 11 by a rotation movement of axis parallel to the
axis X of the additional part 11 with respect to the cover 5 and
with respect to the base 3.
[0153] In the closed position of the case 1, the hooks 13 are held
in the housings 15 by the cover 5 which replaces the protrusion 15a
from the first embodiment. After rotation of the additional part
11, the hooks 13 are located aligned with the slots 24 of the cover
5 and can thus be released. The case 1 can open as can be seen in
FIG. 9.
[0154] The opening of the cover 5 is particularly facilitated by
the presence of the seal 21 which loosens and ensures a preopening
of the case 1 by around 3.degree.. The user can finish the opening
of the case 1 by pivoting the cover 5 assembled to the additional
part 11 to the open position illustrated in FIG. 10.
[0155] Advantageously, as represented in the different embodiment
variants of the two embodiments, the base 3 is intended to receive
a cosmetic product and/or a cosmetic product applicator, for
example by the intermediary of at least one cup 35. Advantageously,
the cosmetic product includes a volatile and/or damp
composition.
[0156] The base 3 can also include a separate bottom 37 as can be
seen in FIGS. 1 and 6. The bottom 37 is attached to the base 3 by
any suitable means, for example, by interlocking, clipping,
screwing, welding or gluing. A separate bottom facilitates, in
particular, the production of the base 3 by molding, in particular
in the case of plastic cases.
[0157] Advantageously, the cover 5 is capable of receiving a mirror
39 of the pocket mirror type. The mirror 39 is attached to the
cover 5, in particular on the inner surface of the cover 5, by any
suitable means, for example by interlocking, clipping, screwing or
gluing. Users can thus apply make-up wherever they are, by looking
in the mirror 29. Thanks to the specific opening/closing system of
the case 1, the cover 5 can easily include a mirror 29 on the inner
face thereof.
[0158] Advantageously, the different parts are made of
thermoplastic materials, for example, polypropylene (PP),
polyethylene (PE), polyoxymethylene (POM), polybutylene
terephthalate (PBT), acrylonitrile butadiene styrene (ABS), styrene
acrylonitrile (SAN), styrene acrylonitrile/acrylonitrile butadiene
styrene (SAN/ABS) or polycarbonate/acrylonitrile butadiene styrene
(PC/ABS), preferably ABS, SAN/ABS or PC/ABS which are materials
that have a more aesthetic finish.
[0159] To obtain additional advantageous effects, the variants and
the embodiments can be combined without moving away from the scope
of the invention.
[0160] In the cosmetic case 1 according to the invention, the seal
21 is arranged on the base or the cover and ensures a sealing of
the case. The sealing is improved by the presence of a multipoint
locking. Thus, the locking means 13 are distributed over the
circumference of the case 1 and ensure sufficient pressure on the
seal 21 to maintain a sealing, not only against impurities but also
against fluids, such as liquids, between the interior and the
exterior of the case.
[0161] In addition, the case 1 includes an additional part 11 which
can be moved with respect to the cover 5. This enables the passage
from the closed position to the open position of the case 1 by
applying a more significant force, thus a seal 21 can be arranged
between the cover 5 and the base 3 without complicating the opening
or closing.
[0162] In addition, the additional part 11 enables to avoid
possible friction between the seal 21 and the cover 5 and in
particular, premature wear of the seal and damaging the sealing of
the case 1.
[0163] Moreover, the conventional locking, in particular by
pushbutton, is replaced by a differential force system. The user
activates the locking manually and thus the pushbutton system can
be avoided.
[0164] More freedom in the design of the case is possible. A very
thin cosmetic case 1 can thus be considered, with a very refined
design, without any visible locking/unlocking element.
[0165] Also, it can be provided to integrate the additional
elements at the level of the cover 5, such as a mirror, given that
the opening is triggered by moving an additional part 11
surrounding the cover 5 and that the cover 5 is not obstructed by a
possible pushbutton. The present invention may be embodied within a
system, a method, a computer program product or any combination
thereof. The computer program product may include a computer
readable storage medium or media having computer readable program
instructions thereon for causing a processor to carry out aspects
