Description

Technical Field

[0001] The present invention relates to a dispenser for a fluid product, the dispenser being configured to be detachably mounted on a reservoir containing the fluid product.

[0002] The invention also relates to a container comprising such a dispenser.

[0003] The fluid product is of the type of, for example, a lotion, a gel, a perfume, a serum or a cream for cosmetic purposes or for medical treatments. Background Art

[0004] There are dispensing systems designed to be equipped with containers and to enable the fluid product to be received and dispensed. Typically, these dispensing systems include a piston that can be moved in translation from an idle position to a collection or dispensing position. This translational movement is usually achieved by a button (or actuator) that is translationally connected to the piston, and pressure, in particular direct pressure, applied by the user on the button (or actuator) causes the piston to move and collect and / or dispense a dose of the fluid product.

[0005] Such systems can be found, for example, in dropper-type containers, in which the collection and dispensing of the product must be done precisely in small doses. These systems replace conventional systems comprising a flexible bulb that enables the product to be drawn and / or dispensed into a straw contained in a reservoir containing the product. A first pressure enables the product to be drawn and a second pressure enables the product to be dispensed.

[0006] These systems generally also comprise a reset device for the piston and the button which enables them to return automatically to the idle position once a dose of fluid has been collected and / or dispensed. In other words, the piston returns to the idle position without any action by the user and activates the button which also returns to the idle position.

[0007] Usually, the reset device is a spring, in particular a helical spring. In order to ensure effective return of the piston and the button, in particular in terms of life, the spring is usually made of metal.

[0008] As a result, these systems are typically composed of numerous components that are not convenient to assemble and render the system uneconomical to manufacture.

[0009] This also increases the risk of system failure. For example, due to wear, gaps may form between the various components, or the return of the piston and / or the button may not be fully achieved. As a result, the stroke is incomplete and the dose of fluid is lower than expected, or the system may become blocked or become difficult to use.

[0010] Furthermore, components may be made of different materials, in particular those materials that are suitable for the function of the component, which complicates recycling.

[0011] Therefore, there is a need for a solution that addresses at least some of the shortcomings of the prior art while maintaining a system that is advantageously simple and economical to manufacture. Summary of the invention

[0012] The invention thus relates to an actuation head configured to be mounted on a fluid dispenser body comprising a straw.

[0013] The actuation head comprises a piston, an actuator, and a reset device, wherein the translation of the piston and the actuator from the actuation end position to the idle position enables the fluid product to be sucked into the straw and the translation of the piston and the actuator from the idle position to the actuation end position enables the fluid product to be dispensed outside the straw; the reset device enables the piston and the actuator to return to the idle position. The piston, the actuator and the reset device are made of a single plastic part.

[0014] By actuator, it is meant a button on which pressure, in particular direct pressure, exerted by the user causes the piston to move and to collect and / or dispense a dose of fluid.

[0015] The return device enables the piston and the actuator to return automatically, in other words spontaneously, ie the piston and the actuator return to their idle position by themselves after being lowered, without requiring intervention by the user.

[0016] The integration of the piston, actuator and return device also enables a smooth return movement. Unlike conventional helical springs, there is no sudden movement of the piston and actuator back to the idle position. The return movement is easier to control.

[0017] This also prevents one of the components from becoming defective, or one of the components from becoming misaligned, which could cause the dispenser with which the dispensing head is used to malfunction.

[0018] Finally, recycling of the dispenser, and therefore of the container with which it is used, is made easier because the entire unit is made of plastic.

[0073] By convention, the “axial” direction in the figures corresponds to the direction of the main axis X of the dispenser 10 for fluid products, wherein the dispenser 10 is configured to be removably mounted on a reservoir 12 of fluid products, and the “radial” direction is orthogonal to the axial direction.

[0074] In the following detailed description of the drawings, the terms "upper" and "lower" or "top" and "bottom" will be used without limitation with reference to the axial direction.

[0075] Similarly, the terms "external" and "inner" are used with reference to a radial direction, outer elements being radially further from the axis X than inner elements.

[0076] Figure 1 and Figure 2 A first embodiment of a container 13 is shown, comprising a dispenser 10 for a fluid product, which is removably mounted on a reservoir 12 .

[0077] “Removable” or “detachable” means that the reservoir 12 can be assembled and removed from the dispenser 10 (particularly in the case of dispensing a fluid product) without damaging or deforming either of the two elements.

[0078] For example, the fluid product may be a lotion, gel, perfume, serum or cream for cosmetic purposes or medical treatment.

[0079] The dispenser 10 comprises an actuation head 14 and a dispensing body 16. A removable connection between the dispenser 10 and the reservoir 12 is achieved via the dispensing body 16.

[0080] The allocation entity 16 includes:

[0081] - a straw 18, and

[0082] A closure system which seals the reservoir 12 when the dispensing body 16 is mounted thereon.

[0083] The straw 18 is configured to make it possible to store a fluid product for dispensing and to contain it inside the reservoir 12 .

[0084] The reservoir 12 is configured to contain a fluid product and to receive a straw 18 .

[0085] The closure system ensures the sealing of the reservoir 12 when the straw 18 is housed in the reservoir 12 .

[0086] The reservoir 12 comprises a longitudinal wall 20 and a top opening 22 . The longitudinal wall 20 delimits an internal space in which the fluid product can be stored. The upper opening 22 is delimited by a neck 24 connected to the longitudinal wall 20 by a frustoconical shoulder 26 .

[0087] The closure system consists of a closure ring 28 that is configured to be removably attached to the reservoir 12 .

[0088] To this end, the closing ring 28 comprises closing means 30 cooperating with closing means 32 of the reservoir 12 .

[0089] The closing means 30 of the closing ring 28 are situated on the inner surface of the lower skirt 34 .

[0090] The lower skirt 34 extends downwardly from the transverse wall 36 .

[0091] The closure means of the reservoir 12 are situated on the outer surface of the neck 24 .

[0092] These closing means are thread systems 30, 32. The closing ring 28 can thus be attached to and / or removed from the reservoir 12 by rotating the closing ring relative to the reservoir.

[0093] The dispensing body 16 also includes an upper skirt 38 that defines an inner housing extending from the straw 18 .

[0094] Thus, the inner housing forms a storage chamber 40 in fluid connection with the straw 18. More specifically, the lower portion of the upper skirt 38 is connected to the upper end of the straw 18 by the transverse wall 36. The opposite lower end of the straw 18 is open and is configured to be immersed in the reservoir 12 when the closure ring 28 is mounted thereon.

[0095] The straw 18 is used to store doses of fluid collected for dispensing.

[0096] In this first embodiment, the dispensing body 16 also comprises an outer skirt 42 .

[0097] The outer skirt 42 surrounds the closing ring 28 and the actuating head. The outer skirt 42 thus makes it possible to hide these less aesthetically pleasing elements, in particular those constituting the actuating head.

[0098] Advantageously, in the embodiment shown, the straw 18, the closed ring 28 and the outer skirt 42 forming the dispensing body 16 are integral. In other words, the straw 18, the closed ring 28 and the outer skirt 42 forming the dispensing body 16 form a one-piece component. Thus, design and assembly become easier. There is also no risk of gaps between the components as use proceeds.

[0099] Preferably, the assembly is made of plastic to make it easier to recycle the dispenser and therefore the container for which the dispenser is intended.

[0100] The second embodiment is different from the first embodiment in that the second embodiment has an outer envelope 43 .

[0101] Advantageously, the outer envelope 43 is connected to the dispensing body 16 in a rotatable and translatable manner.

[0102] In particular, in this second embodiment, the outer envelope 43 is connected in a rotational manner to the dispensing body 16 via the outer skirt 42 through the cooperation of vertical grooves located at the lower and upper ends of the outer envelope 43 and the dispensing body 16 .

[0103] Furthermore, the outer skirt 42 and the outer envelope 43 of the dispensing body 16 are connected in a translatable manner by latching together at the lower and upper ends of the outer skirt 42 and the outer envelope 43 .

[0104] For example, the outer wrapper 43 may be used to provide additional design and improve the aesthetics of the container 13 .

[0105] In the embodiment shown here, the actuating head 14 comprises an actuator 44 , a piston 46 and a return device 48 enabling the piston 46 and the actuator 44 to be returned to the rest position.

[0106] By actuator, it is meant a button on which pressure (in particular direct pressure) exerted by the user causes the piston to move and collect and / or dispense a dose of fluid.

[0107] According to the invention, the piston 46, the actuator 44 and the resetting device 48 are made from a single plastic component. In other words, the piston 46, the actuator 44 and the resetting device 48 form a one-piece component.

[0108] In other words, unlike conventional systems including a separate coil spring, compression, squeezing of the return device 48 directly causes the piston 46 to descend without any intermediate components. The piston 46 is actuated by the actuator 44 and the return device 48 .

[0109] This configuration enables the actuator 44, the return device 48 and the piston 46 to be securely held. This facilitates the return of the actuator 44 and the piston 46 to their idle positions and also allows uniform and stable movement over a long period of time.

[0110] Preferably, the piston 46, actuator 44, and reset device 48 are made from polypropylene (eg, post-consumer recycled polypropylene).

[0111] Polypropylene is a plastic with a well-known recycling cycle.

[0112] Advantageously, the actuation head 14 is mounted on the dispenser body 16 so that the actuator 44 is movable in axial translation relative to the outer skirt 42 and the outer envelope 43 of the dispenser body 16 .

[0113] In the embodiment shown here, the dispenser body 16 comprises an upper housing 50 in which the resetting means 48 are housed. The upper housing 50 and the resetting means 48 are covered by the outer skirt 42 of the dispenser body 16.

[0114] In the second embodiment, the outer envelope 43 also covers the upper receiving portion 50 and the resetting device 48 .

[0115] In the embodiment shown here, the piston 46 extends from the upper transverse wall 52 of the actuator 44 towards the interior of the container 13. In other words, the piston 46 protrudes from the upper transverse wall of the actuator 44.

[0116] In particular, the actuator 44 has a housing in which the piston 46 is located.

[0117] When the actuator head 14 is mounted on the dispensing body 16, the piston 46 is accommodated in the reservoir 40 of the dispensing body 16 and has an outer diameter substantially similar to the inner diameter of the reservoir 40 so that translation of the piston 46 can cause the cosmetic to be drawn into the straw 18 or dispensed.

[0118] In fact, with the actuator 44 connected in a translatable manner to the piston 46 , the pressure on the actuator 44 causes the piston 46 to descend in the storage chamber 40 from its idle position to an end position for collection or dispensing.

[0119] Similarly, raising of actuator 44 causes piston 46 to rise.

[0120] Thus, a dose of fluid product is collected and / or dispensed by a vertical translational movement of the actuator 44 which causes a translational (or sliding) movement of the piston 46 in the reservoir 40 .

[0121] Preferably, the piston slides in a sealed manner to facilitate the collection and distribution of the fluid product.

[0122] When the straw 18 is empty, the rise of the piston 46 causes the fluid to be collected and fills the straw 18 in the reservoir 12 of fluid.

[0123] When the straw 18 contains a fluid product, the piston 46 is lowered so that the fluid product contained in the straw 18 is dispensed.

[0124] Advantageously, the return means 48 enable the piston 46 and the actuator 44 to return to the rest position.

[0125] The return takes place automatically, in other words spontaneously, ie the piston 46 and the actuator 44 return to their idle position by themselves after lowering, without requiring user intervention.

[0126] Thus, when the user releases the actuator 44, the assembly returns to the idle position automatically and autonomously, ie, without requiring user intervention.

[0127] Figures 4 to 8 Several examples of actuator heads 14 that differ in the nature of the resetting means 48 are shown.

[0128] In each of these examples of realization, the return device 48 forms a chamber 54 which is delimited by a wall and in which the piston 46 is housed.

[0129] Advantageously, the wall of the resetting means 48 is flexible.

[0130] In this way, the flexibility of the walls enables the height of the cavity 54 to vary during the translational movement of the actuator 44 .

[0131] Thus, the chamber 54 has a variable height Hmax, Hmin. The height is maximum when the piston 46 and the actuator 44 are in the idle position, which is the height Hmax, and minimum when the piston 46 and the actuator 44 are in the actuation end position, which is the height Hmin.

[0132] Therefore, when the piston 46 and the actuator 44 are in the idle position, the height is the maximum height Hmax.

[0133] As the piston 46 and the actuator 44 descend, the height of the chamber 54 is reduced to a minimum height Hmin. Thus, the piston 46 and the actuator 44 are located in the end position of collection or distribution.

[0134] In other words, the reset device 48 has Figure 1 The extended position shown corresponds to the idle position and Figure 2 The retracted position shown corresponds to the end position of collection or dispensing.

[0135] Advantageously, the flexible wall is a transverse flexible wall. In other words, the cavity 54 is delimited by a transverse flexible wall.

[0136] In the example shown, the resetting means 48 (in this case a flexible wall) is connected to and continuous with the actuator 44. The resetting means 48 and the actuator 44 then have substantially the same diameter.

[0137] In other embodiments not shown, the return device 48 is connected to the piston 46 and is continuous with the piston 46. The return device 48 then has a diameter substantially the same as the diameter of the piston 46.

[0138] Here, “continuously” means that the resetting device 48 is directly connected to the actuator 44 and / or the piston 46 , in particular without any intermediate parts and / or elements.

[0139] The flexible wall may be a solid wall or a perforated wall.

[0140] Advantageously, the wall of the resetting device 48 is formed by a plurality of material strips 56. The material strips 56 delimit a cavity 54 in which the piston 46 is housed.

[0141] Advantageously, the resetting device 48 comprises a lower retaining ring 58 . The retaining ring 58 makes it possible to keep the resetting device 48 in place in the dispenser body 16 .

[0142] In particular, when the wall of the resetting device 48 is formed by material strips 56 , each material strip 56 is connected at its lower end to a positioning ring 58 , thereby ensuring that the material strips 56 remain in place and in particular that there are good spacings between the material strips 56 .

[0143] Preferably, the positioning ring 58 rests on the closure ring 28, for example on the transverse wall 36 of the closure ring 28, and the resetting device 48 surrounds the upper skirt 38 of the closure ring 28, as shown in the embodiment shown. In other words, the upper skirt 38 of the closure ring 28 is located in the cavity 54 of the resetting device 48.

[0144] In respectively Figures 1 to 4 , Figure 5 and Figure 6 In the first, second and third embodiments of the reset device 48 shown in , the wall of the reset device 48 is formed by a plurality of material strips 56 which spirally extend from an upper end protruding from the actuator 44 toward an opposite lower end and are connected to a positioning ring 58.

[0145] exist Figures 1 to 4 In the first example of a resetting device 48 shown in FIG. 4 , the wall of the resetting device 48 is formed by four material strips 56 which extend helically and are wound around the piston 46 in the same direction of rotation.

[0146] The helical winding ensures flexibility of the wall of the resetting device 48 and a variable height of the wall of the resetting device 48 .

[0147] exist Figure 5 In the second example of a resetting device 48 shown in FIG. 4 , the wall of the resetting device 48 is formed by two material strips 56 which extend helically and are wound around the piston 46 in the same direction of rotation.

[0148] exist Figure 6 In the third example of a reset device 48 shown in FIG. 4 , the wall of the reset device 48 is formed by four material strips 56 extending helically and winding around the piston 46 in two opposite rotational directions. In other words, two material strips 56 are wound in a clockwise direction and two material strips 56 are wound in a counterclockwise direction, so that the material strips 56 cross at specific points.

[0149] exist Figure 7In the fourth example of a reset device 48 shown in FIG. 4 , the wall of the reset device 48 is formed by a material strip 56 which is a transverse annular shape extending from the actuator 44 . In other words, the material strip 56 extends annularly around the piston 46 .

[0150] The wall of the restoring device 48 is therefore formed by transverse rings which are stacked parallel to one another and connected by material bridges 60 .

[0151] The material bridges 60 ensure flexibility of the wall of the restoring device 48 and the variability of the height of the wall of the restoring device 48 .

[0152] In this example, the material bridges 60 are offset from one another.

[0153] In other embodiments not shown, the material bridges are aligned.

[0154] The upper ring is connected to the actuator 44 via a material bridge 60. The lower ring corresponds to the positioning ring 58.

[0155] exist Figure 8 In a fifth example of a reset device 48 shown in FIG. 4 , the flexible wall is formed by three strips of material 56 that protrude from the outer surface of the piston 46 and are evenly spaced around the piston 46. The strips 56 extend longitudinally from an upper end 60 located on the outer wall of the piston 46 to an opposite lower end 62 where the strips 56 are connected to a retaining ring 58. The strips 56 are evenly distributed on the retaining ring 58.

[0156] Thus, each strip 56 extends downwardly so that the cavity 54 has a concave shape towards the lower portion of the dispenser 10 .

[0157] The flexibility of each strip 56 makes it possible to make variable the height Hmax, Hmin of the chamber 54 of the return device 48 and to enable the piston 46 and the actuator 44 to return to the idle position.

[0158] Advantageously, the dispenser 10 is made of a single material. Preferably, the dispenser 10 is made entirely of plastic.

[0159] In other words, the actuation head 14 and the dispensing body 16 are made of the same material or at least of similar materials.

[0160] By similar materials it is meant materials that will have at least one recycling path in common.

[0161] The use of the same material, or at least similar materials, to manufacture the various components of the refill 16 is particularly advantageous for recycling these components after use of the fluid product. In fact, the presence of different materials presents a disadvantage when it comes to recycling, namely that the various components must be separated. The use of the same material enables all the components of the refill 16 to be thrown away together, without having to disassemble the refill 16, which facilitates recycling.

[0162] The material can be selected from polypropylene (PP), polyethylene terephthalate (PET), recycled polyethylene terephthalate (R-PET), thermoplastic elastomer (TPE), polyethylene (PE) (e.g., low density polyethylene (LDPE) and / or high density polyethylene (HDPE)), composites, post-consumer recycled (PCR) materials and / or similar materials.

[0163] Preferably, the material is selected from polypropylene, polyester terephthalate, post-consumer recycled polypropylene, post-consumer recycled polyester terephthalate, or mixtures thereof.

[0164] Polypropylene and polyethylene terephthalate are two plastics that have well-known recycling cycles.

[0165] Typically, the reservoir 12 is made of glass. The reservoir 12 may also be made of plastic, wood, metal, a mixed material, or a mixture of these materials.

[0166] Disassembly between the actuation head 14 and the dispensing body 16 and between the dispensing body 16 and the reservoir 12 is relatively easy, and the reservoir 12 is made of different materials so that recycling is not complicated, each component being recycled in its own recycling cycle.

[0167] Advantageously, the container 13 is made of a single material, preferably plastic, such as polypropylene.
