Description

Title of the invention: Cap for a dispensing bottle for a fluid product. Technical field of the invention

[0001] The invention relates to a cap for a dispensing bottle of a fluid product.

[0002] The invention also relates to a dispensing bottle for a fluid product comprising such a cap.

[0003] In the context of the present invention, the fluid product is a liquid cosmetic product, more particularly a perfume, an eau de toilette, or a fragrance. Technical background

[0004] A cosmetic product bottle includes a removable cap mounted on a dispensing head above a reservoir suitable for storing the fluid product.

[0005] The cover has a housing for the dispensing head, so as to conceal it because it is not aesthetically pleasing. The cover primarily prevents any accidental dispensing of product by preventing the dispensing head from being activated.

[0006] Caps for cosmetic product bottles are perceived by the user as elements of appreciation of the market value of the product, so that a cap of a certain weight and of a certain aesthetic will be associated with a perceived value.

[0007] The hood consists of a trim piece having a recess inside which is an insert piece.

[0008] The trim piece is aesthetic, and designed in a noble material, to give value to the hood.

[0009] The insert piece, for its part, does not need to be aesthetic because it is hidden in the cover piece, but it is functional, and serves as an intermediary to allow the cap to be fixed to the bottle reservoir.

[0010] The insert piece is a hollow cylindrical sleeve open on both sides and fixed to the cover piece by gluing.

[0011] In the store, the user wishes to smell the liquid product contained in the bottle. It is common practice for them to remove the bottle's cap and spray a dose of product into the recess in the bottle's cap through the insert. The product thus flows to the bottom of the recess and seeps between the insert and the cover piece by capillary action, eventually coming into contact with the adhesive. Over time, a chemical reaction occurs with the adhesive, causing it to degrade, leading to a risk of the two parts separating and the release of an unpleasant odor. Summary of the invention

[0012] The present invention aims to overcome the various disadvantages stated above, by means of a cap for a dispensing bottle of a fluid product, which is aesthetic, and into which the user can spray fluid cosmetic product without affecting its mechanical stability over time, and without releasing odor.

[0013] The hood according to the invention is provided with a central axis X and comprises:

[0014] - an X-axis housing piece having a central recess opening onto a lower wall of the cladding piece;

[0015] - an X-axis insert piece disposed inside the recess of the part of dressing and fixed in the dressing piece by gluing, said insert piece having a hollow body defining a housing suitable for receiving a dispensing head of the bottle.

[0016] This hood is characterized primarily in that the body of the insert piece has a first closed end forming a bottom of the housing, and in that the body of the insert piece has a vent hole.

[0017] The main idea of ​​this invention is to provide an insert piece having a first closed end near the bottom of the recess, forming the bottom of the housing. Thus, when the product is sprayed into the insert piece, the product will be located at the bottom of the insert piece, unable to escape until it evaporates, and unable to access the junction area between the trim piece and the insert piece where the adhesive is located.

[0018] In the absence of contact between the fluid product and the glue, there can be no chemical reaction, and therefore there can be no risk of degradation of the glue's strength, nor of release of bad odor.

[0019] To ensure proper distribution of the adhesive between the two parts during assembly, it is necessary to evacuate the air trapped between them when the insert is inserted, especially since the bottom of the insert is now closed, creating overpressure when it is inserted into the trim piece. Therefore, a vent hole is added, allowing the air trapped between the insert and the trim piece to escape into the insert's housing during assembly. With the excess air escaping, the insert is positioned optimally against the trim piece, and the adhesive can be distributed evenly between the two parts. The vent hole also allows the adhesive to dry more effectively.

[0020] Having only one vent hole, of minimal diameter, prevents the flow of fluid product into the space between the insert and the hood.

[0021] Indeed, a small amount of air remains trapped between the insert and the casing once they are assembled. When liquid is poured into the insert, for example when a user sprays a dose of product, This liquid exerts pressure on the air trapped through the vent hole. However, this pressure is not sufficient to compress the air and allow the liquid to enter.

[0022] Furthermore, depending on the location of the vent hole on the body of the insert piece, the liquid level does not even reach the vent hole, and there is no contact between the liquid and the vent hole. The liquid then evaporates rapidly.

[0023] According to the different embodiments of the invention, which may be considered together or separately: - the first end of the insert piece body is located near a bottom of the recess in the trim piece. - the body of the insert piece is open at a second end near the lower wall of the cladding piece and gives access to said housing. - the external shape of the insert piece body matches the internal shape of the recess in the trim piece. - a gap is defined between the insert piece and the trim piece. - the vent hole is made at the level of the first closed end of the body of the insert piece. - the vent hole is made at the level of a peripheral wall of the body of the insert piece. - the vent hole is through-hole. - the vent hole opens into the housing. - the vent hole opens into the gap between the insert piece and the piece clothing. - the hood includes means for positioning the insert piece relative to the trim piece, by matching shapes. - said positioning means consist of a rim provided on the insert piece which fits into a reception area provided on the trim piece. - said rim extends radially outwards relative to the X axis from the second end of the body of the insert piece. - said reception area consists of a counterbore made around the recess on the lower surface of the cladding piece. - the glue is spread over the peripheral wall of the body - the glue is spread on the edge of the insert piece. - The hood includes means for centering the insert piece relative to the trim piece. - said centering means consist of a guide ramp for the edge when it is inserted into the reception area, said ramp consisting of an inclined peripheral wall delimiting the reception area. - the insert piece is made of plastic material. - the insert piece is made of metallic material. - the trim piece is made of a high-quality material, such as glass or ceramic, or wood. - the hood has a polygonal cross-section. - the hood has a shape of revolution around the X axis. - the recess in the cladding piece has a circular section. - the housing in the insert room has a circular section. - the insert piece has removable means for fixing to the dispensing head or the bottle reservoir.

[0024] The invention also relates to a dispensing bottle for a fluid product, of the cosmetic product type, comprising a cap according to one of the preceding claims mounted on a dispensing head above a reservoir suitable for storing the fluid product. Brief description of the figures

[0025] Other features and advantages of the invention will become apparent upon reading the detailed description that follows, for an understanding of which reference should be made to the accompanying drawings in which:

[0026] Fig. 1 is an exploded perspective view of a hood according to the invention, with a first configuration of the insert piece;

[0027] The [Fig.2] is a perspective view of the insert piece of the [Fig.1];

[0028] The [Fig.3] is a front view of the insert piece of the [Fig.1];

[0029] Figure 4 is a perspective view of a second configuration of an insert part. according to the invention. Detailed description of the invention

[0030] In the following description, elements having an identical structure or analogous functions will be designated by the same references.

[0031] By convention, the "axial" direction corresponds to that of main extension of the hood, illustrated by the X axis in the figures, and the "radial" direction is orthogonal to the axial direction.

[0032] In the detailed description of the figures that follows, the terms "upper" and "lower" shall be used without limitation with reference to the axial direction. Thus, the term "upper" refers to a part located in the vicinity of the upper part of the hood, and the term "lower" refers to a part located in the vicinity the lower part of the cap which is capable of interfering with a reservoir or a dispensing head of a bottle.

[0033] Similarly, the terms "outside or external" and "inside or internal" are used with reference to the radial direction, an outside element being radially further away from the X axis than an inside element.

[0034] Fig. 1 shows a hood 1 according to the invention, in exploded view, with a trim piece 2 and an insert piece 3.

[0035] The hood 1 extends along a central X axis which also corresponds to the mounting axis of the insert piece 3 in the trim piece 2, and which also corresponds to the central axis of the trim piece 2 and to the central axis of the insert piece 3.

[0036] The dressing piece 2 is a rather massive piece, whose role is to give an aesthetic appearance, in order to embellish a bottle.

[0037] This refers to a bottle comprising a reservoir for storing a liquid cosmetic product. For example, it could be a bottle of perfume, eau de toilette, or fragrance. The cosmetic product is therefore preferably liquid.

[0038] The casing piece 2 can be made of any type of material. Preferably, the casing piece 2 is made of a high-quality material with a certain weight, such as glass, ceramic, wood, etc.

[0039] But the cover piece 2 can also be made of plastic or metal.

[0040] The insert piece 3 is a rather discreet and thin piece, whose role is to provide a The functional aspect of the cap 1 is designed so that it can be correctly mounted on the bottle. Preferably, the insert piece 3 is made of a plastic or metallic material.

[0041] The cap 1 is intended to be mounted on a reservoir of the bottle, and this while concealing a dispensing head of the cosmetic product.

[0042] In the present case, the housing part 2 consists of a cubic part viewed from the outside. However, any type of external shape can be envisaged within the scope of the present invention. For example, the hood 1 could be cylindrical, or spherical, etc.

[0043] The casing piece 2 has a lower wall 5 intended to be positioned opposite the bottle reservoir, and an upper wall 4 located on the opposite side.

[0044] The trim piece 2 has a central recess 6 which opens onto the lower wall 5, the upper wall 4 being closed.

[0045] In the present case, the recess 6 has a circular cross-section. However, other forms of the recess 6 can be envisaged within the framework of the present invention.

[0046] This recess 6 allows the insert piece 3 to be accommodated.

[0047] The insert piece 3 comprises a hollow body 11 closed at a first end 13 and open at a second end 18.

[0048] The body 11 has a peripheral wall 12 of cylindrical shape.

[0049] The first closed end 13 is intended to come to the bottom of the recess 6 of the dressing piece 2.

[0050] The second open end 18 is intended to come flush with the lower wall 5 of the cover piece 2, so that the insert is completely hidden inside the cover piece 2.

[0051] The body 11 of the insert piece 3 has an external shape which fits the internal shape of the recess 6 of the trim piece 2. Thus the insert piece 3 fits perfectly into the recess 6.

[0052] The insert piece 3 and the trim piece 2 are joined by gluing. Glue is applied to the outer surface of the insert body 11 and spreads over the inner surface 10 of the recess 6 during the assembly of the two pieces. Preferably, a gap separates the outer wall of the insert piece 3 from the inner wall 10 of the recess 6 of the trim piece 2, in order to allow some space for the glue to ensure its homogeneous distribution.

[0053] A vent hole 17, visible in Figures 2 and 3, is provided in the body 11 of the insert piece 3 to allow the air trapped in the gap between the insert piece 3 and the trim piece 2 to escape during their assembly. This air vent also creates air circulation which helps the glue to dry.

[0054] In this configuration, the vent hole 17 is made at the first closed end 13 of the body 11 of the insert piece 3. The vent hole 17 is located in the center of the first closed end 13 of the insert piece 3. In addition, this specific location of the vent hole 17 makes it easier to demold the insert piece 3 during its manufacture.

[0055] This vent hole 17 has a very small diameter.

[0056] Preferably, it has a diameter less than or equal to 1.2 mm.

[0057] For example, this hole 17 has a diameter between 0.9 mm and 1.2 mm.

[0058] This hole is so small that if a dose of the product were to be distributed in the room of insert, it would not exert enough pressure to succeed in compressing the air trapped between the insert piece and the trim piece and thus it cannot pass through the hole or come into contact with the glue.

[0059] Another possibility is to make the vent hole 17 at the level of a peripheral wall of the body 11 of the insert piece 3. The vent hole 17 is then no longer located at the bottom of the housing, but at a higher level, and if a dose of product were to be distributed in the insert piece, it would not reach the level of the vent hole 17. There is therefore no risk of contact between the product and the glue.

[0060] Preferably, the vent hole 17 has a small diameter and is located at the level of the peripheral wall of the body 11.

[0061] Advantageously, the insert piece 3 has a rim 15 extending radially outwards with respect to the X axis, at the level of its second open end 18.

[0062] During the assembly of the hood 1, this rim 15 comes into contact with the lower wall 5 of the trim piece 2, and thus acts as an axial stop when mounting the insert piece 3 in the trim piece 2.

[0063] In order that this rim 15 is not visible from the outside, a groove 7 is provided for this purpose at the level of the lower wall 5 of the covering piece 2, thus forming a reception area 7 for the rim 15.

[0064] For example, this groove 7 consists of a counterbore which makes it possible to hide the rim 15. This groove 7 is made at the lower perimeter of the recess 6.

[0065] Advantageously, this groove 7 allows the rim 15 to be accommodated and thus the insert piece 3 to be correctly positioned in relation to the trim piece 2.

[0066] There is therefore a correspondence of shape between the groove 7 and the rim 15.

[0067] In order to center the insert piece 3 relative to the trim piece 2, the groove 7 is provided with an inclined peripheral wall 9, with a diameter decreasing from the lower wall 5 of the trim piece 2 towards the recess 6. Thus the rim 15 of the insert piece 3 can slide on this inclined peripheral wall 9 until it comes to be correctly positioned at the bottom 8 of the groove 7 while being perfectly centered.

[0068] This inclined peripheral wall 9 acts as a guide ramp.

[0069] Glue can also be placed between the rim 15 of the insert piece 3 and the bottom 8 of the groove 7 of the trim piece 2 in order to further increase the bonding surface.

[0070] The interior of the insert piece 3 is hollow and defines a housing 14 for receiving the dispensing head of the bottle. The first closed end 13 forms the bottom of the housing 14.

[0071] To aid in mounting the cap 1 onto the bottle, the insert piece 3 includes at least one notch 16, of the flat type, on its inner wall which can cooperate with a corresponding shape provided on the neck of the reservoir, for example, or on any other part of the bottle, so that the cap 1 is held securely in place. For example, these shape correspondences can prevent the cap 1 from rotating relative to the rest of the bottle.

[0072] Any other removable fastening system between the cap 1 and the rest of the bottle may be envisaged within the framework of the present invention.

[0073] Figure 2 shows a second possible configuration of an insert piece 3 according to the invention. The entire description above applies to this insert part 3, with a few differences:

[0074] - the vent hole 17 is located at the junction between a bottom wall forming the first end 13 of the body 11, and a peripheral wall 12 of the body 11;

[0075] - the notch 16' is of a different shape, in this case it starts at the first third of the depth of the insert piece 3, and stops at half the depth of the insert piece 3. Preferably there are several 16' notches distributed around the perimeter of the insert piece 3. In this case there are three 16' notches.

[0076] In the configuration shown in [Fig.2], the insert piece 3 has a shoulder 19 at mid-length resulting in a reduction of the diameter, making it easier, for example, to remove the insert piece 3 from its mold.

[0077] The configurations shown in the cited figures are only possible examples, by no means limiting, of the invention which on the contrary encompasses variants of forms and designs within the reach of a person skilled in the art.
