Description

Dispensing head for a receptacle for a cosmetic or pharmaceutical product, refill equipped with such a dispensing head and refillable assembly formed from such a refill

Technical field of the invention

The invention relates to a dispensing head for a receptacle for a cosmetic or pharmaceutical product, and in particular a dispensing head provided with a pump. The invention also relates to a refill equipped with such a dispensing head. Finally, the invention relates to a rechargeable assembly formed from such a refill.

Technical background

It is known to equip a receptacle for a liquid or semi-liquid cosmetic product of the cream or pharmaceutical type with a dispensing head provided with a pump. The pump communicates on the one hand with a reservoir of the receptacle containing the cosmetic or pharmaceutical product and on the other hand with a dispensing orifice formed at the level of the dispensing head. The pump thus ensures delivery of the cosmetic or pharmaceutical product from the reservoir of the receptacle to the dispensing orifice.

In known manner, the pump is arranged along a main vertical axis of the dispensing head. As a result, the dispensing head has a relatively large size along this main vertical axis. Thus, when the dispensing head is mounted on a cosmetic or pharmaceutical product receptacle along a main vertical direction of this receptacle, the system thus formed has a large size in the direction of alignment of the receptacle and the dispensing head.

Such bulk poses a difficulty in storing the system, for example in a small handbag. In addition, such a bulk poses a difficulty in handling the system. Indeed, the handling of the system is generally done with one hand: the receptacle is positioned in the palm of the hand and held in position by one or more fingers while the dispensing head is positioned opposite a finger remained free. The flexion of this free finger then makes it possible to exert a thrust on the dispensing head.

For a receptacle-dispensing head system having a relatively large size, keeping the receptacle in position in the palm of the hand and actuating the dispensing head by bending the free finger can be a source of discomfort for the user. user.

In order to limit the size of a dispensing head provided with a pump and to facilitate the handling of a receptacle equipped with such a dispensing head, the prior art teaches solutions in which the pump is arranged in a direction horizontal of the distribution head. However, these solutions result in making the structure of the dispensing head more complex and in particular introduce an actuation system which is not very compatible with the natural flexion of a finger.

The invention aims to solve at least in part the drawbacks of the state of the art.

According to a first aspect, the invention proposes a dispensing head for a cosmetic or pharmaceutical product receptacle, the dispensing head comprising:
-a hoop configured to be fixed on the receptacle;
- a pump mounted in the hoop, the pump being configured to be in communication with the receptacle, and

According to this first aspect of the invention, the pump has an axis, called the axis of inclination, forming with a main vertical axis of the hoop an acute or right angle. The push button is configured to receive a thrust along an axis, called the thrust axis, so as to move in an oblique or horizontal translation and drive the pump in an oblique or horizontal translation along the axis of inclination. The thrust axis forms an acute angle or a right angle with the tilt axis of the pump. By oblique translation is meant a translation along a horizontal direction and a vertical direction.

Thus, according to this first aspect, the invention introduces an axis of inclination of the pump distinct from the main vertical axis of the hoop and/or distinct from the thrust axis. This makes it possible to reduce the size of the dispensing head, in particular along the vertical axis, while offering the user the possibility of actuating the dispensing head with one hand along a thrust axis permitted by the movement. of natural flexion of a finger of the hand.

Detailed description of the invention

In the rest of the description, elements having an identical structure or analogous functions will be designated by the same reference.

In the remainder of the description, the following will be adopted in a non-limiting manner:

- a longitudinal orientation which is directed from the front to the rear in the direction of the arrow "L" in the figures;

- A vertical orientation which is directed from the bottom upwards in the direction indicated by the arrow "V" in the figures; and

- A transverse orientation which is orthogonal to the vertical orientation and indicated by the arrow "T" of the figures.

“Front” means the face of the refillable unit, of the refill or of the dispensing head where the dispensing orifice is located.

The term "rear" means the face of the refillable unit, of the refill or of the dispensing head opposite to the face where the dispensing orifice is located.

The term "bottom" means the face of the refillable assembly, of the refill or of the dispensing head positioned near the ground or near a support surface of said assembly, of said refill or of said dispensing head. when said assembly, said refill or said dispensing head is in a vertical position.

The term "top" means the face of the refillable assembly, of the refill or of the dispensing head positioned opposite the face located near the ground or a support surface of said assembly, of said refill or said dispensing head.

The terms "upper" will also be adopted on a non-limiting basis to designate elements located towards the top of the refillable assembly, of the refill or of the dispensing head, and "lower" to designate elements located towards the bottom of the refillable assembly, refill or dispensing head.

Similarly, the terms “inner” will be adopted without limitation to designate an orientation towards a main vertical axis of the refillable assembly of the refill or of the dispensing head and “outside” to designate an orientation moving away from said axis. .

As illustrated in Figures 1 and 2, the invention relates to a refillable assembly 1 comprising a base 1A, a refill 1B of cosmetic or pharmaceutical product, as well as a cap 1C. The rechargeable assembly 1 extends along a main vertical axis V. The base 1A, the refill 1B and the cap 1C each extend along the same main vertical axis V.

The base 1A is configured to reversibly receive the refill 1B. The term “reversible” is understood to mean that it is possible to detach two parts fixed together in a reversible manner without damaging said parts or the fastening means. The base 1A thus covers a lower portion of the refill 1B.

The cap 1C holds the refill 1B in position in the base 1A. In addition, the cap 1C covers an upper portion of the refill 1B.

With reference to the , the base 1A comprises a main body 21 which forms an internal volume 22 intended to receive the refill 1B. The base 1A further comprises a neck 23 positioned above the main body 21. The main body 21 and the neck 23 form a shoulder 24. The neck 23 is provided with ribs 25.

In the illustrated embodiment, the ribs 25 are 4 in number. In addition, the ribs 25 are regularly distributed over the neck 23. Finally, the ribs 25 are each in the form of an inverted L with a horizontal branch upper 25a and a lower vertical branch 25b.

It should be noted that the ribs 25 allow coupling between the cap 1C and the base 1A. The particular shape of the L-shaped ribs 25 allows quarter-turn opening and/or closing of the cap 1C on the base 1A when changing the refill 1B.

With reference again to the , the refill 1B comprises a 1D receptacle, here of cylindrical shape, as well as a 1E dispensing head mounted on the 1D receptacle. The dispensing head 1E extends along a main vertical axis which coincides with the main vertical axis of the refill 1B. This is the main vertical axis V of set 1 as shown in .

Referring to Figures 4, 5 and 6, the receptacle 1D comprises a drum 31 in which is mounted a crucible 32 intended to contain the cosmetic or pharmaceutical product. The barrel 31 extends along a main vertical axis which coincides with the main vertical axis of the refill 1B. This is the main vertical axis V of set 1 shown in . In addition, the barrel 31 has a flange 33 which divides it into a lower portion 34 and an upper portion 35.

It should be noted that the lower portion 34 of the barrel 31 has a closed bottom 34a. The upper portion 35 of the barrel 31 forms an opening 35a intended to receive the crucible 32 and the dispensing head 1E.

As shown in , the crucible 32 is held in position in the barrel 31 by means of a lower insert 36 and an upper insert 37. To do this, the crucible 32 has an upper portion 32a, here of cylindrical shape, as well as a lower portion 32b of reduced height and section. The lower insert 36, here of cylindrical shape, has an upper portion 36a of geometry complementary to that of the lower portion 32b of the crucible 32 (see ). Thus, the lower portion 32b of the crucible 32 is configured to engage in the upper portion 36a of the lower insert 36. The upper insert 37 comprises a lower portion 37a which forms a lower edge 37b intended to come into contact with a upper edge 32c of the crucible 32 (see ).

Thus, the lower insert 36 and the upper insert 37 respectively form a lower stop and an upper stop of the crucible 32 in the barrel 31.

It should be noted that the lower insert 36 also has a lower portion 36b opposite the upper portion 36a. Similarly, the upper insert 37 has an upper portion 37c opposite the lower portion 37a. Thus, according to a cross-sectional view in a transverse vertical plane of the receptacle 31 (see ), the lower insert 36 and the upper insert 37 each have an H profile. In other words, the lower insert 36 and the upper insert 37 have the same profile, here an H profile.

In relation to FIGS. 7, 8 and 9, the dispensing head 1E will now be described. This dispensing head 1E comprises a collar 4, a pump 5 and a push button 6. In particular, the collar 4 is intended to be mounted at the level of the upper portion 35 of the barrel 31. The pump 5 is housed in the hoop 4. Push button 6 is positioned above pump 5. In addition, push button 6 is intended to actuate pump 5.

According to the invention, the pump 5 extends in the hoop 4 along an axis, called the axis of inclination, which forms with a main vertical axis of the hoop 4 an angle α, acute or right. The main vertical axis of hoop 5 corresponds to the main vertical axis V of assembly 1 as shown in . The angle α is defined in a horizontal vertical plane.

Referring to Figures 10 and 11, hoop 4 comprises a vertical wall 41, here of cylindrical shape, which is intended to be fitted into opening 35a formed by upper portion 35 of shaft 31. In addition, hoop 4 has a longitudinal transverse wall, called horizontal wall 42, which extends above the vertical wall 41.

The horizontal wall 42 of the hoop 4 is equipped with a sleeve 43 intended to receive the pump 5. To do this, the sleeve 43 has an upper edge 43a and a lower edge 43b between which extends a housing 44. The pump 5 extends into said housing 44. Thus, the sleeve 43 forms a means for guiding the pump 5

The sleeve 43, like the housing 44, extends in an inclined manner through the horizontal wall 42 of the hoop 4. In other words, the sleeve 43, like the housing 44, extends along a axis of inclination X. Thus, the sleeve 43 forms an oblique ramp, called the first hoop ramp.

The axis of inclination of the sleeve 43 coincides with the axis of inclination of the pump 5. Thus, the axis of inclination X of the sleeve 43 forms with the main vertical axis V of the dispensing head 1E a angle which is similar to the angle α formed between the axis of inclination of the pump 5 and the main vertical axis V of the hoop 4.

It should be noted that the housing 44 of the sleeve 43 is accessible from an upper opening 44a and a lower opening 44b defined respectively by the upper edge 43a and the lower edge 43b of the sleeve 43. In addition, the housing 44 of the sleeve 43 has a shoulder 44c on which the pump 5 bears.

In the illustrated embodiment, sleeve 43, like housing 44, is cylindrical in shape. The sleeve 43 and the housing 44 thus have an axis of revolution which coincides with the axis of inclination X.

Still with reference to Figures 10 and 11, the horizontal wall 42 of the hoop 4 is equipped with two longitudinal

vertical projections

45a, 45b. These

projections

45a, 45b are parallel to each other in a longitudinal direction. In addition, these

projections

45a, 45b are parallel and equidistant from the axis of revolution of the sleeve 45. Finally, these

projections

45a, 45b each have a

notch

46a, 46b formed in a horizontal vertical plane.

The

notches

46a, 46b, called second hoop ramps, are each inclined with respect to the main vertical axis V of the dispensing head 1B. More specifically, the

notches

46a, 46b extend along an axis of inclination which is parallel to the axis of inclination X or to the axis of revolution of the sleeve 43, and therefore parallel to the axis of inclination X of the pump 5.

In the illustrated embodiment, the axis of inclination X of each

notch

46a, 46b forms with the main vertical axis V of the dispensing head 1E an angle of 45°.

With reference again to the and as best illustrated at the , the pump 5 comprises a fixed part and a movable part. The fixed part comprises a first body 51, here of cylindrical shape, which is intended to be mounted in a fixed manner in the housing 44 of the sleeve 43. The fixed part also comprises a second body 52, here of cylindrical shape, which is mounted in the first body 51 via an insert 53.

Thus, in the illustrated embodiment, the first body 51, the second body 52 and the insert 53 each have a shape of revolution.

In particular, the first body 51 of the pump 5 has an upper end 51a which forms a rim intended to rest on the shoulder 44c formed at the level of the housing 44 of the sleeve 43. The first body 51 of the pump 5 extends thus into the housing 44 of the sleeve 43 and emerges through the lower opening 44b of this housing 44 to plunge into the barrel 31. In other words, the first body 51 of the pump 5 has a lower portion, called the plunging portion 51b, which extends outside the sleeve 43. This plunging portion 51b engages in a volume 38 formed by the upper portion 35 of the barrel 31.

It should be noted that the plunging portion 51b of the first body 51 of the pump 5 has a lower end piece 51c of reduced section. This lower nozzle 51c is provided with an opening 51d intended for the passage of the cosmetic or pharmaceutical product from the receptacle 1D to the pump 5. In addition, this lower nozzle 51c is equipped with a valve 54 intended to regulate the flow of the product admitted in pump 5 (see ).

With reference to the , the insert 53 has an outer wall 53a intended to bear against the first body 51 of the pump 5. The insert 53 also has an intermediate wall 53b which forms with the outer wall 53a an annular space 53c. Finally, the insert 53 has an inner wall 53d which forms a passage 53e. It should be noted that the passage 53e of the insert 53 has a shoulder 53f.

With reference again to the and as best illustrated at the , the second body 52 of the pump 5 has a collar 52a which divides it into a lower portion 52b and an upper portion 52c. The collar 52a rests on the rim 51a of the first body 51 of the pump 5.

The lower portion 52b of the second body 52 of the pump 5 is positioned entirely in the first body 51 of the pump 5. In particular, this lower portion 52b comprises a lower edge 52d which is positioned in the annular space 53c of the insert 53. It should be noted that near its lower edge 52d, the lower portion 52b of the second body 52 of the pump 5 comprises a radial internal stop 52e.

The upper portion 52c of the second body 52 of the pump 5 extends outside the first body 51 of the pump 5, opposite the receptacle 1D. This upper portion 52b remains partly in the housing 44 of the sleeve 43 and emerges from this sleeve 43 opposite the receptacle 1D. In particular, this upper portion 52c has an upper edge 52f which overhangs the upper edge 43a of the sleeve 43.

As best illustrated at , the movable part of the pump 5 comprises a piston 55 slidably mounted in the fixed part. The piston 55 comprises a tube 56 which has an upper end 56a and a lower end 56b between which a housing 56c extends. In addition, the tube 56 of the piston 55 has near its upper end 56a a peripheral skirt 56d. Finally, the tube 56 of the piston 55 is equipped with a return means 57 and a valve 58.

In particular, the peripheral skirt 56d is configured to come into contact with an internal wall of the second body 52 of the pump 5. This peripheral skirt 56d forms with the tube 56 of the piston 55 an annular space 56e as well as a radial shoulder 56f. The return means 57, here a spring, is positioned in the annular space 56e formed between the peripheral skirt 56d and the tube 56. This return means 57 extends along the axis of inclination X of the pump 5 between the radial inner stop 52e of the second body 52 of the pump 5 and the radial shoulder 56f formed by the peripheral skirt 56d and the tube 56.

Thus, the return means 57 compresses or expands between the radial inner stop 52e which is fixed and the peripheral skirt 56d which is mobile. The peripheral skirt 56d forms both a sliding member for the piston 55 in the fixed part of the pump 5 and a holding member for the return means 57 around the piston 55.

By its compression and its expansion, the return means 57 allows the piston 55 of the pump 5 to pass from a low position in which the piston 55 is largely retracted in the fixed part of the pump 5 towards a high position in which the piston 55 is largely outside the fixed part of the pump 5.

As best illustrated in Figures 9a and 9b, the valve 58 comprises a stem 58a for mounting in the tube 56 as well as a valve body 58b, here of frustoconical shape, which is connected to the stem 58a.

Rod 58a is mounted in tube 56 through lower opening 56b of said tube. In addition, the rod 58a is provided with an upper end piece 58c, here of frustoconical shape, intended to rest on a shoulder 56c formed in the tube 56 of the piston 55.

The valve body 58b forms a rim 58d intended to bear against the outer wall 53a of the insert 53 when the piston 55 is in the high position. Furthermore, this body 58b forms with the valve stem 58a a housing 58e intended to receive a lower edge of the inner wall 53c of the insert 53 when the piston 55 is in the high position.

Referring again to Figures 7, 8 and 9, the push button 6 comprises a longitudinal arm 61 which extends along an axis of extension, here perpendicular to the main vertical axis V of the dispensing head 1E. The longitudinal arm 61 has a first longitudinal end 61a provided with a connector 62 and a second longitudinal end 61b near which a longitudinal vertical tab 63 extends. In addition, the longitudinal arm 61 is configured to receive a thrust along a thrust axis P.

According to the invention, the thrust axis is distinct from the axis of extension of the longitudinal arm 61. In addition, this thrust axis is distinct from the axis of inclination X of the pump 5.

In the illustrated embodiment, the thrust axis is parallel to the main vertical axis V of the dispensing head. As a variant, the thrust axis can be substantially inclined with respect to the main vertical axis V of the dispensing head 1E while remaining distinct from the axis of inclination X of the pump 5.

With reference to the , the connector 62 of the push button 6 has a housing 62a accessible from an opening 62b formed by a lower edge 62c of the connector 62. The connector 62, like its housing 62a, extends along an axis of inclination which coincides with the axis of inclination X of the sleeve 43 or of the housing 44. The axis of inclination of the connector 62 or of the housing 62a forms with an axis of extension of the longitudinal arm 61 an angle β. The axis of inclination of the connector 62 or of the housing 62a forms with the main vertical axis V of the dispensing head 1E an angle β'.

Thus, the connector 62 is configured to receive the pump 5, and more specifically the upper end 56a of the tube 56 forming the piston 55 of the pump 5.

In the illustrated embodiment, the angle β, that is to say the angle formed between the axis of extension of the longitudinal arm 61 and the axis of inclination X of the connector 62 (or of the housing 62a ) is 45°. Similarly, the angle β' formed between the axis of inclination X of the connector 62 (or of the housing 62a) and the main vertical axis V of the dispensing head 1E is equal to 45°.

With reference again to the , the longitudinal arm 61 of the push button 6 forms a conduit 61c for conveying the cosmetic or pharmaceutical product from the pump 5 to a dispensing orifice 64 located at the second longitudinal end 61b of the longitudinal arm 61. The conduit 61c communicates in particular with the tube 56 forming the piston 55 of the pump 5.

With reference again to the , the longitudinal vertical tab 63 of the push button 6 extends below the longitudinal arm 61. This longitudinal vertical tab 63 has a free lower end which is provided with two transverse lugs 63a. The

lugs

63a, 63b are positioned on either side of the longitudinal vertical leg 63, and more specifically on the longitudinal vertical faces of this longitudinal vertical leg 63. These

lugs

63a, 63b are intended to engage in sliding in the

notches

46a, 46b formed at the level of the longitudinal

vertical projections

43a, 43b of hoop 4.

Thus, hoop 4 comprises a second guide means for push button 6 which is configured to cooperate with a third guide means arranged on push button 6. The second guide means comprises

notches

46a, 46b formed at the level of the vertical projections longitudinal 45a, 45b of hoop 4. The third guide means is formed by

lugs

63a, 63b. The second guide means and the third guide means are configured to cooperate so as to cause the translational movement of the pump 5, and more specifically the translational movement of the piston 55.

It should be noted that the translation movement of pump 5 takes place along a translation axis which coincides with the axis of inclination X of pump 5.

Push button 6 and piston 55 of pump 5 move between a high position ( ) and a low position ( ). In the low position, the

lugs

63a, 63b abut against the bottom of the

notches

46a, 46b. The lower edge 62b of the connector 62 abuts against the upper edge 52f of the second body 52 of the pump 5. In the high position, the

lugs

63a, 63b are at a distance from the bottom of the

notches

46a, 46b. The lower edge 62b of the connector 62 is at a distance from the upper edge 52f of the second body 52 of the pump 5.

With reference again to the and as best illustrated at the , the cap 1C comprises a connector 7, a cover 8 and a shell 9. In particular, the connector 7 is intended to be fixed to the base 1A. Thus, the connector 7 ensures a coupling between the cap 1C and the base 1A.

The cover 8 is intended to be mounted on the connector 7. In this way, the cover 8 makes it possible to hide the connector 7 when the cap 1C is mounted on the base 1A. It should be noted that the cover 8 and the connector 7 are fixed with respect to the base 1A.

The shell 9 is slidably mounted relative to the cover 8 and to the connector 7. In addition, the shell 9 is intended to be positioned at the level of the push button 6 of the dispensing head 1E. The shell 7 thus forms a pusher intended to transmit to the push button 6 the thrust exerted by a user.

With reference to the , the connector 7 is formed by a vertical body 71, here of cylindrical shape.

The vertical body 71 of the connector 7 forms a perimeter provided with vertical openings 71a. This perimeter has interior projections 71b which extend in a radial direction. The vertical openings 71a, here 4 in number and regularly distributed around the circumference, are intended to receive the ribs 25 formed on the neck 23 of the base 1A. It should be noted that the internal radial projections 71b, here 4 in number and regularly distributed around the periphery of the vertical body 71, each form a seat for the horizontal portion 25a of a rib 25 of the base 21.

Furthermore, the vertical body 71 of the connector 7 has a lower edge which is provided with a radial extension 72, as well as an upper edge which is provided with two

vertical projections

73a, 73b.

In particular, the radial extension 72 has a perimeter provided with lugs 74, here 4 in number and regularly distributed along the perimeter of the radial extension 72.

The

vertical projections

73a, 73b each extend over a fraction of the periphery of the vertical body 71 forming the connector 7. In other words, the

vertical projections

73a, 73b each have an arcuate shape, with a concavity turned towards the main vertical axis V of the cap 1C. In addition, the

vertical projections

73a, 73b are diametrically opposed on either side of the main vertical axis V. Finally, the

vertical projections

73a, 73b are each surmounted by a vertical arch 75a, 75b and a

rim interior

76a, 76b.

It should be noted that the

arches

75a, 75b are each arranged in a longitudinal vertical plane of the cap 1C. The

flanges

76a, 76b extend in a longitudinal transverse plane of the cap 1C. These

flanges

76a, 76b are intended to be positioned above the horizontal wall 42 of the hoop 4. Thus, the

flanges

76a, 76b make it possible to press the refill 1B against the base 1A.

Referring to Figures 20 and 21, the cover 8 has a vertical wall, here of cylindrical shape, which has a front face 81 provided with a front notch 81a and a rear face 82 provided with a rear notch 82a. The

notches

81a, 82a each define an

edge

81b, 82b, here of curvilinear shape, of the cylindrical vertical wall. The

notches

81a, 82a and the

edges

81b, 82b defined by these notches are respectively U-shaped. The edges each have a circumferential portion and a vertical portion. Subsequently, the

edges

81b, 82b will be designated respectively “front edge” and “rear edge”.

On either side of the front 81a and rear 82a notches extend two

opposite faces

83, 84 forming the cylindrical vertical wall of the cover 8, two interior longitudinal

vertical walls

85, 86 as well as two transverse

longitudinal walls

87, 88. The

vertical wall

81, 82 forms a housing in which the connector extends.

The interior longitudinal

vertical walls

85, 86 each have a

notch

85a, 86a which extends in a longitudinal vertical plane of the cap 1C. These

notches

85a, 86a each define an

edge

85b, 86b of the

corresponding wall

85, 86. In the illustrated embodiment, the

notches

85a, 86a as well as the

edges

85b, 86b defined by these

notches

85b, 86b respectively present in a longitudinal vertical plane an inverted U-shaped profile. The

edges

85b, 86b each have a longitudinal portion and a vertical portion.

It should be noted that the interior longitudinal

vertical walls

85, 86 are positioned on either side of a median longitudinal axis of the cap 1C. These interior longitudinal

vertical walls

85, 86 thus form an access opening to the housing of the cover 8.

The front 81 and rear 82 faces as well as the side faces 83, 84 of the cylindrical wall of the cover 6 are each provided with a groove. Here, only the

grooves

81c, 83c are illustrated. These

grooves

81c, 83c as well as those not shown are intended to receive the lugs 74 of the connector 7 so as to ensure coupling between the cover 8 and the connector 7. The grooves are each formed close to a lower edge of its face. corresponding 81, 82, 83, 84.

It should be noted that the cylindrical vertical wall of the cover 8 has internal vertical ribs 89 intended to reinforce the structure of the cover 8. These ribs 89 are formed substantially at the level of the lines of intersection of the faces 81 to 84.

In another embodiment not illustrated, the vertical wall has a substantially cubic shape with straight or substantially straight faces. The vertical wall comprises a front transverse vertical face and a rear transverse vertical face between which extend two outer longitudinal vertical faces and two inner longitudinal vertical faces.

In this embodiment, not illustrated, the front and rear transverse vertical faces each have an upper notch which extends in a transverse vertical plane of the cap 1C. These notches each define an edge of the corresponding face. The notches and the edges defined by these notches are respectively U-shaped. The edges each have a transverse straight portion and a vertical straight portion.

Referring to Figures 22 and 23, the shell 9 comprises a front vertical wall 91 and a rear vertical wall 92 between which extend two longitudinal

vertical walls

93, 94 and a transverse longitudinal wall 95. Here, the front vertical walls 91 and rear 92 are curved. In a variant not shown, these

walls

91, 92 can be substantially straight.

The longitudinal transverse wall 95 of the shell 9 is intended to be positioned above the longitudinal arm 61 of the push button 6. This transverse longitudinal wall 95 has an underside which is provided with a rib (not shown) intended to come into contact with the longitudinal arm 61 of the push button 6.

The rear vertical wall 92 of the shell 9 is intended to be positioned at the rear of the connector 62 of the push button 6. This rear transverse vertical wall 92 is positioned facing the U-shaped notch 82a formed by the rear face 82 of the cylindrical vertical wall of the cowl 8. Thus the rear vertical wall 92 of the shell 9 is at least partly cleared, which makes it possible to limit the friction between the shell 9 and the cowl 8.

The longitudinal

vertical walls

93, 94 of the hull 9 are intended to slide respectively along the inner longitudinal

vertical walls

85, 86 of the cover 8. Each longitudinal

vertical wall

93, 94 of the hull 9 comprises at least one flexible portion allowing mounting by elastic fitting of the shell 9 in the cover 8.

In the illustrated embodiment, each longitudinal

vertical wall

93, 94 of the shell 9 comprises two

flexible end portions

93a, 93b, 94a, 94b positioned on either side of a central

flexible portion

93c, 94c. These flexible portions 93a -93c, 94a -94c are delimited by vertical slots.

The

flexible end portions

93a, 93b, 94a, 94b are respectively provided with

lugs

95a, 95b which are intended to cooperate with the

edges

85b, 86b defined by the

notches

85a, 86a of the interior longitudinal

vertical walls

85, 86 of the cover. 8. Thus, the position of the

lugs

95a, 95b in abutment against the

edges

85b, 86b makes it possible to limit the upward stroke of the shell 9 with respect to the cover 8.

The central

flexible portions

93c, 94c each have a lower edge provided with an outer projection 96. These projections 96 extend in a transverse longitudinal plane of the cap 1C. In addition, these projections 96 are intended to rest on the

arches

75a, 75b of the connector 7 when the shell 9 is in the high position relative to the cover 8.

The front vertical wall 91 of the shell 9 is intended to be positioned in front of the front end 61a of the longitudinal arm 61 of the push button 6. In other words, the front vertical wall 91 of the shell 9 is intended to be positioned in front of dispensing orifice 64.

In addition, the front vertical wall 91 of the shell 9 is positioned facing the U-shaped notch 81a of the front face 81 forming the cylindrical vertical wall of the cover 8. Thus, the front vertical wall 91 of the shell 9 is at the less partially cleared, which makes it possible to limit the friction forces between the shell 9 and the cover 8.

Finally, with reference again to the , the front vertical wall 91 of the shell 9 comprises a flexible membrane which is configured to be traversed by the longitudinal arm 61 of the push button 6 during a push exerted on the push button 6. More specifically, following a pressure exerted on the push button 6 and a return of this push button 6 to its initial position, the dispensing orifice 64 performs a to-and-fro movement through the flexible membrane of the front vertical wall 91 of a shell 9. Thus, the front vertical wall 91 of the shell 9 performs a function of wiping the dispensing orifice 64.

In the illustrated embodiment, the flexible membrane includes a slot 91a.

The shell 9 is mounted in the cover 8 through the opening formed by the interior longitudinal

vertical walls

85, 86 of the cover 8. The shell 9 thus mounted in the cover 8 is movable between a high position (FIGS. 24 and 25) and a low position (FIGS. 26 and 27).

The low position of shell 9 in cover 8 corresponds to a low position of push button 6 with respect to hoop 4, and therefore to an actuation state of pump 5. In addition, the low position of shell 9 in the cover 8 corresponds to an outlet of the longitudinal arm 61 of the push button 6 through the front transverse vertical wall 91 of the shell 9, and more precisely through the slot 91a of this vertical transverse wall.

The high position of the shell 9 in the cover 8 corresponds to a high position of the push button 6 with respect to the hoop 4, and therefore to a stop state of the pump 5. In addition, the high position of the shell 9 in the cover 8 corresponds to a retracted position of the longitudinal arm 61 of the push button 6 with respect to the front vertical wall of the shell.

In the embodiment described above, the connector 7 and the hoop 4 are two distinct parts associated respectively with the cap 1C and with the refill 1B. In another embodiment illustrated in Figures 28 and 29, one and the same part 100 serves as connector 7' and hoop 4'. In other words, a 7' connector and a 4' fret form one and the same part 100.

Part 100 incorporates the main characteristics of connector 7 previously described in relation to the first embodiment except for the

vertical projections

73a, 73b and the

vertical arches

75a, 75b. In addition, part 100 incorporates the main characteristics of hoop 4 previously described in relation to the first embodiment except for the longitudinal

vertical projections

43a, 43b and the

notches

46a, 46b.

It should be noted that hoop 4' and connector 7' of part 100 form a groove intended to receive receptacle 1D, and in particular the upper portion 35 of barrel 31 forming receptacle 1D.

The second embodiment also differs from the first embodiment by the configuration of the cover. Referring to Figures 30 and 31, the cover 8 'according to the second embodiment incorporates the main characteristics of the cover 8 previously described in relation to the first embodiment. The cover 8' according to the second embodiment also has a front oblique wall 81', called the first front oblique ramp, and a rear oblique wall 82', called the first rear oblique ramp.

The first front oblique ramp 81' is formed at the front upper notch 81a. The first rear oblique ramp 82' is formed at the rear upper notch 82a. The first front oblique ramp 81' and the first rear oblique ramp 82' are parallel. The first front oblique ramp 81' and the first rear oblique ramp 82' each extend along an axis of inclination which is parallel to the axis of inclination X of the sleeve 43, and therefore parallel to the axis of inclination of the pump 5.

Still with reference to FIGS. 30 and 31, the first front oblique ramp 81' and the first rear oblique ramp 82' each extend between the interior longitudinal

vertical walls

85, 86. The first front oblique ramp 81' extends towards the high from a circumferential portion of the front edge 81b. The first rear oblique ramp 82' extends downward from a circumferential portion of the rear edge 82b.

Thus the first front oblique ramp 81 overhangs the first rear oblique ramp 82'.

The second embodiment differs from the first embodiment also by the configuration of the pusher.

In the first embodiment described above, the pusher is formed by a separate shell 9 from the push button 6. In the second embodiment illustrated in , a part 200 comprises a push button 6' and a push button 9'. In other words, a push button 6' and an over-push button 9' form a single part 200. Hereafter, part 200 is referred to as a “push button”.

The pusher 9' according to the second embodiment incorporates the main characteristics of the pusher 9 as described in the first embodiment above with the exception of the longitudinal

vertical walls

93, 94. In addition, the pusher 9' according to the second embodiment has at the level of the front vertical wall 91' a lower bevelled edge 91a', called the second front oblique ramp. This pusher 9' also has at the level of the rear vertical wall 92' a lower bevelled edge 92a', called the second rear oblique ramp.

The second front oblique ramp 91a' and the second rear oblique ramp 92a' are parallel. In addition, the second front oblique ramp 91a' and the second rear oblique ramp 92a' each have a slope which extends along an axis of inclination parallel to the axis of inclination X of the sleeve 43, and therefore parallel to the axis of inclination. axis of inclination of the pump 5.

In the example illustrated in FIG. 32, the second front oblique ramp 91a' of the booster 9' overhangs the second rear oblique ramp 92a'. In other words, the front face 91' carrying the second front oblique ramp 91a' has a lower height than that of the rear face 92' carrying the second rear oblique ramp 92a'.

Finally, the second embodiment differs from the first embodiment by the nature of the second guide means and the third guide means of the push button.

Indeed, in this second embodiment, the second guide means is no longer formed by the

notches

46a, 46b, but rather by the first front 81' and rear 82' oblique ramps, i.e. by the oblique walls formed at the level of the 8' cover. The third guide means is no longer formed from

lugs

63a, 63b carried by the vertical leg 63, but rather by the second front and rear oblique ramps, i.e. by the bevelled lower edges 91a', 92a' formed at the level of the front 91' and rear 92' vertical walls of the pusher 9'.

In other words, the second oblique ramps 91a', 92a', i.e. the bevelled edges of the pusher 9', are intended to cooperate with the first oblique ramps 81', 82' of the cover 8. More specifically, the second oblique ramps 91a', 92a' are configured to slide along the first oblique ramps 81' , 82' of the cover 8 during the translation of the piston 55 of the pump 5. This sliding movement of the second oblique ramps 91a', 92a' with respect to the first oblique ramps 81', 82', causes a movement of the booster 9' relative to the cover 8 'between a high position illustrated in Figures 33 and 34 and a low position illustrated in Figures 35 and 36.

The 8' cover is configured to be mounted on part 100. The system formed by the 8' cover and part 100 can be considered as a hoop in its own right. The first oblique ramps 81', 82' of the cover 8' can then be considered as a guide means for the push button 200. This guide means is intended to cooperate with the guide means formed by the first oblique ramps, c. i.e. the beveled edges 91a', 92a' of the push button 200.

The various parts described above are manufactured by injection molding or by any other process known to those skilled in the art.
