Description

Cap for mounting refill part of cosmetics

The present invention relates generally to refillable devices for packaging cosmetics.

Such a refillable device may be, for example, a makeup case for making up a face of a face such as eyebrows, cheekbones, or lips.

Makeup products are especially foundations, blushers, eye shadows, lipsticks, lip gloss, or lip balm.

Within the meaning of the present invention, "cosmetics" is understood to be a cosmetic intended to be applied to humans, for example a solid, liquid, or cream, such as a powder. "Cosmetics" refers more generally to the European Parliament and the Council's Commission Regulation (EC) no. 1223/2009.

According to the invention, the cosmetic may be impregnated with a support, for example a foam or a sponge.

Apparatus for packaging cosmetics having an outer casing and a cosmetic refill configured to be received within an outer casing are known. The refill section has means for fastening it to the outer housing.

Several types of refills have already been proposed.

Patent FR 2 755 837 describes a refill with a lid.

Patent FR 2 786 076 discloses a refill with a first wall on the inner radial side defining a chamber for receiving the cosmetic composition and a second radially outer wall for applying a means for hermetically sealing the contents of the refill part, Is added.

In patent application EP2308339,

A hollow body intended to contain a cosmetic product,

Means for fastening the hollow body to the outer casing,

A brittle zone configured to allow at least partial separation of said fastening means from the hollow body by the effect of pulling on said fastening means by the user, A refill portion including a brittle region extending discontinuously is described.

However, the known refill section does not provide a completely perfect seal of the cosmetic, for example, when the refill section has a cover that is connected to the bottom surface only by the bottom surface and the hinge that receives the cosmetic article, such as the refill section described in WO2016 / 083607 .

Especially, there is a need to improve the refill portion of cosmetics for make-up and care products so as to prevent leakage.

It is also apparent that there is a need to obtain an advantage from the tamper-proof refill section, in other words, where the first opening of the refill section causes a irreversible change in its appearance, and subsequently the refill section has already been opened.

- The user is easy to open,

- easy to manufacture, cheap,

- There is also a need to propose a refill with small space requirements.

Definition of invention

A subject of the invention is an X-axis cap intended to fit on a cosmetic refill, comprising a hollow body and at least one gripping tab in the Z-axis connected to the hollow body by at least one frangible region, Wherein the Z-axis of the gripping tab extends at least partially over the height of the side wall of the cap and wherein the retaining relief of the cap is adapted to engage the gripping tabs Which is designed to be released at least in part from the complementary retaining relief of the refill portion due to the effect of pulling on the refill portion.

The main advantage of the cap according to the present invention is that it keeps the refill portion closed to prevent leakage outside the makeup case. This advantage is particularly advantageous for a refill section having a hinge and resiliently deformable sidewalls as described in WO2016 / 083607.

In the case of such a refill part having an elastically deformable side wall, the cap according to the present invention is clip-fastened on the refill part and can keep the side wall in a squeezed state to ensure leakage prevention.

The cap according to the present invention has certain features that keep the plate in a "connected state" to ensure leak protection during storage and transport. The cap can be dismantled after opening.

The cap is easy to manufacture with a thin friable area to allow separation from the refill part.

Due to the specific location of the Z-axis of the tab, the tab ensures proper leakage prevention and is easy for the user to remove.

The present invention also relates to a leak-proof cosmetic refill section comprising a cap as described above which is fitted on a cosmetic refill section.

If the tab is not removed, the user can be assured that the refill has not been used and that the cosmetics packaged by the manufacturer are still being accepted. Conversely, fracturing or tearing of the tab means that the cap may have been detached from the refill and may have been used previously.

The leak-proof type refill portion according to the present invention is an operation-inhibiting type.

The invention also includes:

- providing a leak-proofing cosmetic refill as defined above,

- holding the grip tab between two fingers,

- applying a pull to the grip tab,

- selectively holding the cap with one hand and holding the refill with the other hand, moving them away from each other to achieve access to the cosmetic product.

Main Definition

"A axis" means the longitudinal axis (A).

"A section of a part of the A axis" is a section perpendicular to the A axis of this part.

The expression "longitudinal axis of the grip tab" refers to the line connecting all of the centers of gravity of the sections of the tab.

The "z-axis of the grip tab extends at least partially across the height of the side wall of the cap" means that the Z-axis of the tab extends in at least a portion of the side wall in a manner parallel to, or at an angle to, the X- .

The term "tab" should be understood broadly and includes lugs, strips, tongues, or lamellas.

"The retaining relief of the cap is at least partially released from the complementary retaining relief of the refill" means that the retaining reliefs of the cap and refill portion can be at least partially moved away, separated, deformed, folded, or bent do. Thus, the user can completely separate the cap and the refill part and achieve access to the cosmetic.

Preferred embodiments

Preferably, the device according to the invention comprises one or more of the following features, either individually or in combination:

The z-axis of the grip tab extends over the entire height of the side wall of the cap. The tabs are also easier to catch.

The z-axis of the grip tab extends at least partially over the top wall of the cap. The opening of the cap will open the refill part better.

The friable area is a reduced thickness area comprising a plurality of material bridges separated by reduced thickness lines and / or reduced thickness areas or by through-apertures. It is easy to manufacture.

The grip tab is separated from the body of the cap by at least one slot. This design limits the forces that need to be applied by the user.

The hollow body, the grip tab, and the frangible region are made integral with each other. The manufacturing cost is reduced.

- The Z-axis of the grip tab is located on the center of the cap. The cap is opened in two symmetrical parts that are visually appealing.

The refill section comprises a base defining a storage compartment in the interior and a plate rotatably mounted on the base about a Y axis of the hinge, the plate comprising a closed configuration for closing the storage compartment and a storage compartment And an open configuration accessible to the part. The cosmetic product is protected by a cap and a plate that hold the refill part in the closed position.

The housing is manufactured in the plate and intended to receive a second cosmetic, the housing comprising a bottom surface and a side wall, the side wall being resiliently deformable. The leakage prevention is improved by the elastic wall serving as the sealing portion.

The apparatus shown in Figs. 1 and 2 has a cap 3 to be fitted on the refill part 5. Fig.

The cap may be made of a plastic material, for example HDPE or ABS.

The cap 3 shown in Figures 1 and 2 includes a Z-axis grip tab 14 and a hollow body 44. Which defines an internal volume 17 defined by the cylindrical sidewall 21 and the flat top wall 19 of the X-axis.

The Z-axis of the grip tab 14 extends parallel to the X-axis of the cap over the entire height of the sidewall 19.

The grip tab 14 is axially defined by two longitudinal slots 71, 72. Which is connected to the hollow body 44 by a reduced thickness region 96 located at the outer circumferential edge 145 of the upper wall 19.

The grip tabs 14 and the reduced thickness region 96 are made integral with the body 44 of the cap 3.

Inside, the sidewall 21 has a snap fit bead 111 extending in a plane perpendicular to the X-axis and engageable with a complementary relief of the refill portion 5. [

The outer surface of the top wall 19 has an outer circumferential shoulder 75 which connects the top wall 19 to the side wall 21 and forms an outer stop on the inner surface of the top wall 19. [ This stop is designed to support the complementary relief of the refill part 5 and to restrict its axial movement.

The refill section 5 comprises a base section 12 and a plate 16 rotatable about the base section 12 about the Y axis of the hinge.

The base portion 12 defines a central cavity 25 defined by a flat bottom surface 26 and a cylindrical lower sidewall 27 and a cylindrical upper sidewall 31 that are connected to each other by a shoulder 30. The central cavity 25 defines a compartment 28 intended to receive the first cosmetic product. The upper cylindrical wall 31 extends radially outward from the upper end by a collar 45 extending downwardly by an annular rim 46 of the X-axis.

The plate 16 has a central housing 37 that is open on the flat portion 36 and intended to receive a second cosmetic product. The central housing 37 has a flat bottom surface 38 connected to the flat portion 36 by an elastically deformable side wall 40.

The sidewall 40 is preferably formed of an elastically deformable material, such as a thermoplastic elastomer such as SEBS, or nitrile rubber (NBR), or silicon. Which is overmolded, for example, on the bottom surface 38, and then connected to the flat portion 36.

Outside the side wall 40, the base and the refill portion may be made of a thermoplastic material, particularly ABS or PET / PETG.

The side wall 40 is elastically deformed such that the diameter increases as the flat portion 36 and the collar 45 are moved together and can contact the side wall 31 of the base portion 12. [ Therefore, it acts as a seal in the closed position of the plate 16 on the base 12. [

However, since the refill portion 5 does not have a latch, the plate 16 tends to rise relative to the base portion 12 on the opposite side of the hinge. This is because the resiliently deformable sidewall 40 is axially relaxed and exerts a pressure on the flat portion 36 to move the plate 16 at least locally away from the base portion 12.

The main advantage of the cap 3 is to maintain the refill section 5 in the closed position by realizing the contact between the collar 45 and the flat section 36 around the entire circumference of the refill section 5. [

In order to fit the cap 3 onto the refill portion 5, the cap 3 is snap-fitted along the X-axis in the direction of the refill portion, as shown in Fig. While the cap 3 is fitted, the snap fit bead 111 is squeezed into the annular rim 46. Upon passing through the rim 46, the snap fit bead 111 returns to its initial configuration as shown in FIG. 2 due to its elasticity and irreversibly locks the cap on the refill portion.

To remove the cap 3, the user pulls the free end of the grip tab 14 as shown in Fig. When the pulling force exerted by the user exceeds the tear strength of the reduced thickness region 96, the tab 14 is broken. The user then applies a manual pulling force along the X axis on the side wall 21 of the cap 3 in a direction away from the refill section 5 to completely release the annular rim 46 from the snap fit bead 111 have.

By way of illustration, a second example of a refill section is shown in FIG. The figure shows a hinge 122 connecting the plate 16 to the base 12. [

4 to 12 show a second example of a cap according to the present invention.

The cap (3) includes a top wall (19) connected to the cylindrical side wall (21). Three grip tabs 14, 141 and 142 of Z, Z 'and Z "axes parallel to the X axis of the cap 3 are regularly distributed around the X axis.

The diameter of the cap 3 is advantageously 2 cm to 5 cm, more advantageously 3 cm to 4 cm.

The height of sidewall 21 is advantageously from 1 cm to 3.5 cm, more advantageously from 1.5 cm to 2 cm.

Each of the grip tabs 14, 141, 142 is preferably accommodated within a sector of an axial extent of 30 to 60 degrees, more preferably about 45 degrees, about the X axis.

Each grip tab 14, 141, 142 includes, for example, a clip-fastening tip 80, 81, 82, which is perpendicular to the Z, Z ', Z " The toothed portion engages with the complementary relief of the refill portion (5) before being used for the first time.

Each of the grip tabs (14, 141, 142) comprises:

Two side slots (90, 91, 92, 93, 93) which are received in a sector of an axial extent parallel to the axis of the gripping tab and preferably about 2 to 5 degrees, more preferably about 3 degrees, 94, 95),

- a reduced thickness region 96, 97, 98 located at the connection between each grip tab and the top wall 19, respectively.

As shown in FIG. 6, each reduced thickness region may include two thin regions 961, 962 and one thick region 963.

To remove the cap 3 from the refill section 5, the user lifts the grip tabs 14, 141, 142 in the direction of the arrow to remove the clip- Lt; / RTI > Thereafter, the user moves the refill section 5 away from the cap 3, thereby completely releasing the clip-fastened parts and achieving access to the refill section 5.

13 to 18 show a third example of the cap 3 according to the present invention. In this example, the cross section of the cap 3 is a square having a width of 7 cm. The cap 3 has a single grip tab 14, the Z axis of which is located on the median plane of the cap 3. The Z axis extends over the entire height of the sidewalls 21 and continues over the entire width of the top wall 19.

The grip tab 14 is axially defined by two reduced thickness lines 960 and 961 parallel to the Z axis and has a snap fit tooth shaped portion 85 located on the front side of the tab.

Advantageously, the width of the grip tab 14 is 0.5 cm to 2.5 cm, preferably 1 cm to 1.5 cm.

The sidewall 21 comprises:

Two snap fit teeth 81, 82 formed on half of the side surface 210,

Two snap fit teeth 83, 84 formed on half of side 212, on opposite sides of side 210,

And has a snap fit tooth portion 80 formed on the half of the lower side surface 211 and thicker than the snap fit teeth 81, 82, 83, 84 on the inner side.

The position, structure, and thickness of the snap-fit teeth portions depend on the configuration of the refill portion 5 in which the cap 3 is snap-fitted.

In order to remove the cap 3 from the refill portion 5, the user lifts the holding tab 14 in the direction of the arrow shown in Fig. The user preferably cuts the two reduced thickness lines 960, 961 along their entire extent. The user releases the snap pit tooth portion 85 first. The cap 3 remains on the refill portion 5 while partially held in the axial position by the engagement of the other snap fit teeth and their complementary reliefs. To achieve access to the refill section 5 the user pulls the cap 3 and the refill section 5 in the opposite direction and then the snap fit teeth of the cap 3 reach the reliefs 5 of the refill section 5. [ So that the cap 3 can be completely removed from the refill portion 5.
