Description

The present invention relates to a fluid product refill for filling a bottle having a threaded neck with a fluid product.

The bottle may form part of a dispenser which further comprises a dispensing head, for example with an integrated pump. The dispensing head is removably screwed onto a threaded neck of the bottle. Such dispensers are frequently used in the perfume and cosmetics sector.

British Patent No. 2279069

The present invention aims to refill a bottle with a fluid product after the contents in the bottle have been dispensed through a removable dispensing head. The dispensing head is therefore removed from the bottle by unscrewing it and temporarily replaced with a fluid product refill according to the present invention. The present invention aims to provide a fluid product refill that can be easily and quickly connected to the neck of the bottle to quickly fill the bottle with a fluid product without the risk of losing the fluid product.

Fluid product means any liquid such as perfume, lotion, cream, gel, foundation, etc.

To this end, the fluid product refill of the present invention is for filling a bottle having a threaded neck with a fluid product and comprises a flexible pouch including an opening, and a dispensing assembly including an insert portion and a stopper portion, the insert portion being formed with a sealing attachment, a passageway, and a camway or external threads, the stopper portion being formed with a threaded connecting sleeve having an internal helical thread that matches the threads of the threaded neck of the bottle, and a cam profile or internal threads that engage the camway or external threads, respectively, characterized in that the stopper portion is initially in sealing engagement with the insert portion to close the passageway, and that following or subsequent to threading of the threaded neck of the bottle into the threaded connecting sleeve, the passageway opens as the cam profile or internal threads move within the camway or external threads.

In other words, the fluid product refill according to the present invention is provided in the form of a crushable flexible pouch attached to a pouch support having a thread corresponding to the threads of the threaded neck of the bottle. The fluid product refill can thus be screwed onto the threaded neck of the bottle and then the pouch can be crushed or crushed to expel the fluid product from the pouch into said bottle without risk of loss.

It is the neck of the bottle that rotates the stopper portion, thereby establishing a flow path for the fluid product between the flexible pouch and the bottle. Preferably, the rotation of the stopper portion relative to the insert portion is performed after the neck of the bottle is screwed into the threaded connecting sleeve in the same threading direction, e.g., clockwise as is more natural.

Advantageously, the insert part and the stop part are formed with end stop means for limiting their movement relative to one another. According to one embodiment, the insert part can be formed with a collar and the stop part with an abutment harpoon, which, after being forced below the collar during mounting of the stop part around the insert part, can no longer be removed above the collar.

According to another aspect, only the sealing appendage enters the flexible pouch. The remaining part of the dispensing assembly therefore enters at or around the neck of the bottle, reducing the risk of leakage. On the other hand, it allows a passage for air therein to escape from the bottle filled with the fluent product through the threaded zone of the sleeve, accelerating its filling.

According to a practical embodiment, the camway of the insert part has two ends, namely an inlet end connected to the axial mounting funnel and a blind end acting as a travel end stop means, and a retaining profile advantageously formed at the connection between the axial mounting funnel and the camway keeps the cam profile in the camway and prevents it from returning to the axial mounting funnel.

According to another aspect, the insert portion may include a tube and the stopper portion may include a cuff that engages the circumference of the tube inside the threaded connection sleeve. Preferably, the cuff sealingly slides around the tube between an initial closed position and a final open position upon threading of the threaded neck of the bottle into the threaded connection sleeve.

On the other hand, the insert part may comprise a cylindrical body arranged between the sealing appendage and the tube, and the stop part may comprise a skirt arranged under a threaded connecting sleeve and around the cylindrical body, the cylindrical body being formed with a camway or an external thread and the skirt being formed with a cam profile or an internal thread. Preferably, the threaded connecting sleeve extends over an extension of the skirt. Advantageously, the skirt slides sealingly around the cylindrical body. For example, the inner wall of the skirt may form a lip or annular groove in sliding contact with the cylindrical body. This sealing by sliding contact is in addition to the seal provided between the sleeve and the tube, which eliminates the risk of leakage.

According to another feature of the invention, the stopper portion includes a tamper-evident ring engaged with the insert portion, and threading of the threaded neck portion of the bottle into the threaded connecting sleeve destroys the tamper-evident ring. The tamper-evident ring may be located at the base of the stopper portion and breaks against a locking element on the insert portion when sufficient rotational torque is applied.

The present invention also provides a method of filling a bottle having a threaded neck with a fluid product using a fluid product refill, the method comprising the steps of: (a) engaging a threaded connection sleeve of the stopper portion around the threaded neck of the bottle; (b) rotating the fluid product refill to thread the threaded connection sleeve onto the threaded neck of the bottle; (c) once the threaded connection sleeve is fully threaded onto the threaded neck of the bottle, continuing to apply torque to the fluid product refill to rotate the flexible pouch and insert portion about the stopper portion and bottle; (d) pushing the flexible pouch to expel its contents into the bottle through the dispensing assembly; and (e) removing the fluid product refill from the bottle.

The stopper part is attached so that it is initially integral with the insert part when screwing begins and is integral with the bottle when screwing is completed. The user can release the closing function of the stopper part during a single screwing operation in a single direction without realizing it. Of course, to both screw the neck of the bottle into the threaded connecting sleeve and unscrew the insert part from the stopper part during a single turn in the same direction, the thread direction of the stopper part must be reversed relative to the thread direction of the threaded connecting sleeve.

The invention is essentially a screw-on refill with a flattenable flexible pouch. The stopper portion can ensure complete closure of the fluid product refill when not screwed onto the bottle.

The invention will now be described in more detail with reference to the accompanying drawings, in which some embodiments of the invention are shown by way of non-limiting examples.

First, with reference to FIG. 1, a fluid product refill according to the present invention and its use in a bottle or fluid dispenser will be described.

The fluid product refill is designated by the capital letter R as an assembly and includes two components: a flexible pouch P and a dispensing assembly D1.

The flexible pouch P can be manually flattened and made of any suitable material, such as, for example, laminated sheets (aluminum and plastic material). The pouch P can also be manufactured by blow molding or extrusion. The pouch P has an opening (not shown) to which the discharge assembly D1 is attached, for example, by welding or gluing. As shown in FIG. 1, the discharge assembly D1 protrudes outside the flexible pouch P.

The bottle F has a neck C provided with one or more screw threads T. The bottle F can be made of any suitable material, for example glass, metal, plastic material, etc. The bottle F can be transparent, translucent or opaque. The bottle F can form part of a fluid dispenser further comprising a discharge head H including a pump K, a push button B and a fixing ring M. The discharge head H can be attached to the threaded neck C of the bottle F by means of its fixing ring M by screwing. This attachment constitutes a fluid dispenser. The user presses the push button B to activate the pump K. The pump K dispenses a dose of the fluid product through a discharge outlet B1 formed in the push button B. This is conventional for fluid dispensers in the perfume and cosmetic fields.

The present invention aims to provide a fluid product refill R that allows the bottle F of a fluid dispenser to be filled with a fluid product once the fluid dispenser has been emptied. In practice, the dispensing head H is unscrewed from the threaded neck C of the bottle F. The fluid product refill R according to the present invention is attached to the threaded neck C of the bottle F such that the contents of the flexible pouch P can be poured into the bottle F through the dispensing assembly D1.

Next, with reference to Figures 2 and 3, the structure and operation of the fluid product refill R according to the present invention, and more specifically, its dispensing assembly D1, will be described in detail.

The discharge assembly D1 has two main components: an insert part 1 and a stopper part 2. These two parts can be made by injection molding with plastic material.

The insert 1 comprises a sealing appendage 11, the geometric shape of which is clearly shown in FIG. 3. The sealing appendage 11 has an eye or diamond shaped cross section. This sealing appendage 11 is inserted into the opening of the flexible pouch P and fixed, preferably by thermal welding. The sealing appendage 11 has a passage 10 inside, and only the sealing appendage 11 enters the inside of the pouch P.

The insert part 1 has a cylindrical body 12 formed on the sealing appendage 11, through which the passage 10 passes. The body 12 has two hollow recesses formed on its outer surface, each of which has an outer camway 120 and an axial mounting funnel 123. The camway 120 has an inlet lower end 121 and a blind stopper upper end 122. The camway 120 extends in an arch between these two ends 121 and 122. The axial mounting funnel 123 extends from the upper end of the body 12 to the inlet lower end 121 of the camway 120. The funnel 123 has a funnel portion 125. The funnel portion 125 widens from bottom to top and communicates with a straight portion leading to the inlet end 121 of the camway 120. The connection between the lower end of the axial mounting funnel 123 and the inlet end 121 is provided with a retaining profile 124. This function will be described later.

The insert 1 also includes a tube 13 that extends axially upwards above the cylindrical body 12. The tube 13 also communicates with the passage 10, which in turn communicates with the outside via two lateral openings 130. The tube 13 includes an annular groove 132 that receives an O-ring 133. The upper end of the tube 13 is closed by a small cap 131.

The stopper part 2 is engaged around the body 12 and tube 13 of the insert part 1 as shown in FIG. 2 and includes a skirt 21 extending around the body 12. The skirt 21 has two cam profiles 210 formed on the inside, which can be very simply small cylindrical protrusions. In FIG. 2, the cam profiles 210 are located below the axial mounting funnel 123 and at the inlet end 121 of the camway 120. It will be understood that when the stopper part 2 rotates around the body 12 in this state, the cam profiles 210 move along the camway 120, which has the effect of moving the stopper part 2 axially upward relative to the insert part 1.

The stopper part 2 also comprises a threaded connection sleeve 22 that extends substantially in the extension of the skirt 21. The threaded connection sleeve 22 has one or more internal helical threads 221 formed on its inner surface. The diameter of the threaded connection sleeve 22 and the pitch of the internal helical threads 221 correspond to the diameter and thread pitch of the neck part C of the bottle F. The threaded connection sleeve 22 is intended to be screwed onto the neck part C of the bottle F.

The stopper part 2 also comprises a plate 24 extending radially inwards from the skirt 21 or threaded connecting sleeve 22. The inner peripheral part of the plate 24 is connected to a cuff 23 located above it and extending around the tube 13. It should be noted that the O-ring 133 is in sealing contact with the inner wall of the sleeve-like cuff 23. The threaded connecting sleeve 22 also comprises a free upper end 232 which is in sealing engagement with the small cap 131 of the tube 13. The passage 10 leading to the two lateral openings 130 is therefore unable to communicate with the outside due to the two annular sealing contacts formed axially on either side of each lateral opening 130, namely the sealing contacts of the O-rings 133 and the sealing engagement of the end 232 and the small cap 131. Figure 2 shows the discharge assembly D1 in its initial closed position.

Attachment of the stopper part 2 to the insert part 1 is particularly simple, considering that the engagement of the cam profile 210 in the camway 120 is performed through the axial mounting funnel 123. In practice, it is sufficient to engage each cam profile 210 inside the corresponding funnel portion 125, from where it is guided towards the lower part of the axial mounting funnel 123 leading to the inlet of the corresponding camway 120. A small additional axial pressure may be necessary to pass the cam profile 210 from the funnel portion 125 through the retaining profile 124 located at the inlet of the inlet lower end 121 of the camway 120.

It should also be noted that the blind end 122 of the camway 120 functions as an unscrewing movement end stop. In effect, the cam profile 210 is moved from the inlet end 121 to the blind end 122 and abuts against the blind end 122. This represents the complete and final state of unscrewing of the stopper part 2.

Returning again to FIG. 1, it can be seen that the fluid product refill R can be attached to the threaded neck C of the bottle F in an upside-down position over the threaded neck C such that the threaded connection sleeve 22 engages around the threaded neck C. The user grasps the refill R through the flexible pouch P and rotates the flexible pouch P, or refill R, so as to thread the threaded connection sleeve 22 around the threaded neck C. This initially causes the threaded neck C to slide inside the threaded connection sleeve 22 until it abuts against the plate 24. The user can then continue to rotate the flexible pouch P. This has the effect of rotating the flexible pouch P and its insert portion 1 relative to the stopper portion 2, which is now integral with the threaded neck C. In this case, the two cam profiles 210 are forced to move in the corresponding cam ways 120, which results in breaking the sealing contact between the upper end 232 of the cuff 23 and the small cap 131 of the tube 13. In this way, fluid communication is established between the flexible pouch P and the bottle F through the passage 10, the lateral opening 130, and the outlet passage opening between the upper end 232 and the small cap 131. The O-ring 133 prevents the fluid product between the stopper part 2 and the insert part 1 from leaking toward the body 12.

The user can then push or crush the flexible pouch P to force or expel the fluid product contained therein into the bottle F. Any air initially contained within the bottle F can escape, for example through the unsealed threaded engagement between the threaded neck C and the threaded connecting sleeve 22. Given that the flexible pouch is flattenable, it is not necessary to replace the volume of its liquid contents with air within the flexible pouch.

It can thus be seen that a simple rotation of the flexible pouch P relative to the bottle F produces two successive movements, namely first the screwing of the threaded connecting sleeve 22 onto the threaded neck portion C, and then the unscrewing of the stopper portion 2 relative to the insert portion 1. This sequencing is preferred but not essential. The direction of rotation is preferably unidirectional and right-handed.

Optionally, the lower end of the skirt 21 is provided with a tamper-evident ring 216 (or a first-use failsafe ring) that is connected to the skirt 21 by a break bridge. Meanwhile, the base of the cylindrical body 12 is formed with one or more locking features 126 that engage with the tamper-evident ring 216, preventing rotation of the stopper part 2 on the insert part 1.

However, sufficient torque between the stopper and the insert has the effect of breaking the break bridges, separating the tamper-evident ring 216 from the skirt 21. Any break bridges indicate to the user that the stopper 2 has not been unscrewed from the insert 1. The breaking of the bridges preferably occurs between the operations of threading the threaded sleeve onto the neck and unscrewing the stopper from the insert.

Figure 4 shows a variant of the embodiment which differs from the first embodiment in that the skirt 21' of the stopper part 2' and the cylindrical body 12' of the insert part 1' engage with each other. Indeed, instead of the camway 120 and the cam profile 210, the cylindrical body 12' is now provided with an external thread 120' and the inner wall of the skirt 21' is provided with a corresponding internal thread 210'. For this reason, the mounting of the stopper part 2' to the insert part 1' cannot be performed by pure axial mounting as in the first embodiment, but only by screwing.

Another difference with the first embodiment is that an abutment harpoon 211 is formed on the inside of the skirt 21', which is intended to abut against the underside of the collar 122' formed on the cylindrical body 12', in order to limit the unscrewing of the stopper part 2' on the insert part 1', as shown in FIG. 4. The harpoon 211 can be forced to pass through the collar 122' from above during the installation operation, which requires the stopper part 2' to be screwed onto the insert part 1'. However, due to the detent-shaped configuration of the harpoon 211, it can no longer pass through the collar 122' from the underside to the upper side.

Optionally, the skirt 21' also forms a tamper-evident strip 212 that is destroyed as soon as sufficient torque is applied.

In the variant shown in FIG. 4, the connecting sleeve 22', the tube 13' and the cuff 23' can be identical to those of the first embodiment. The sealing appendage 11' is shorter without changing its function.

Rotary sliding seals are provided between the tube 13' and the cuff 23', and advantageously also between the cylindrical body 12' and the skirt 21'. These seals can take the form of lips or annular grooves that seal with frictional contact. O-rings can also be implemented, as in the first embodiment with O-ring 133.

The fluid product refill with integrated dispensing assembly D2 is used in exactly the same way as dispensing assembly D1 described above. At the end of the above-mentioned operation of screwing the stopper part 2' onto the neck part C, the stopper part 2' is loosened from the body 12' until the abutment harpoon 211 abuts the collar 122' from below. The rotation direction is preferably unidirectional, a continuous right turn. The loosening of the stopper part is performed consecutively to the screwing of the neck part C of the bottle onto the stopper part 2' in one operation, without the user being aware of it. Thus, the fluid product refill is simply screwed onto the bottle. The loosening of the stopper part is not visible to the user.

Figure 5 shows another embodiment, the operation of which differs from the first embodiment. The dispensing assembly D3 comprises an insert part 1'' forming a sealing appendage 11'' closed by the lid 110. The insert part also forms a connecting sleeve 14, which defines an inner thread 141 as well as an outer thread 144. In other words, the sleeve 14 is threaded both inside and outside. In Figure 5, a removable hood 4 can be seen engaged with the threaded sleeve 14. More specifically, this removable hood 4 comprises an upper closure wall 41 and a cylindrical wall 42, the inner side of which is formed with a thread 43 corresponding to the thread 144 of the sleeve 14. The hood 4 also includes a first-use fail-safe ring 44. The hood 4 is sealingly screwed onto the sleeve 14.

The discharge assembly D3 shown in FIG. 5 also includes a puncture needle 3 that engages the inside of the sealing appendage 11'' and the inside of the sleeve 14. The puncture needle 3 defines one or more internal passages 30 and includes a thrust collar 32, a sealing lip 33, and a beveled end 31. The collar 32 is initially positioned inside the sleeve 14 at substantially mid-height. The sealing lip 33 sealingly and slidingly engages the inside of the sealing appendage 11'', which may further include an additional sealing bead 111. The beveled end 31 is positioned near or in contact with a lid 110 that closes the lower end of the sealing appendage 11''. The puncture needle 3 is therefore said to be positioned within an enclosed space defined by the insert 1'' and the removable hood 4.

Although not shown, the dispensing assembly D3 is assembled to the flexible pouch constituting the fluid product refill according to the present invention. First, the user unscrews the removable hood 4 after removing the first-use fail-safe strip 44. This dispensing assembly D3 can be mounted upside down on the bottle F in a manner similar to that shown in FIG. 1. The connecting sleeve 14 is screwed into the threaded neck C of the bottle F. This screwing causes the upper end of the neck C to contact the thrust collar 32 and bias the puncture needle 3. This results in the movement of the puncture needle 3. The puncture needle 3 thus moves axially towards the lid 110, inevitably puncturing the lid 110. In this way, fluid communication is established between the flexible pouch P and the bottle F via the internal passage 30 defined by the puncture needle 3.

In this second embodiment, the screwing of the sleeve 14 into the threaded neck C and the movement of the puncture needle 3 inside the insert part 1'' are performed simultaneously. Since only the puncture needle 3 ensures a passage between the pouch P and the inside of the threaded neck C, the risk of leakage is extremely reduced. In fact, the thrust collar 32 can be seen to be set back from the upper end of the puncture needle 3, allowing the upper end of this puncture needle 3 to enter inside the neck C.

A third particularly simple embodiment is shown in FIG. 6. The dispensing assembly D4 comprises an insert part 1''' that defines a sealing appendage 11''' for a flexible pouch (not shown). The insert part 1''' includes a connecting sleeve 14' that is internally and externally threaded, as in the previous embodiment. The dispensing assembly D4 also comprises a removable hood 4' that screws around the threaded sleeve 14'.

After removing the removable hood 4', the user places the bottle F upside down and back onto the dispensing assembly D4. The user can then naturally rotate the bottle F to screw the threaded neck C inside the threaded sleeve 14'. Once screwed, the user can turn the assembly upside down and push the flexible pouch P to expel the fluid product, which is then contained within the bottle F through the insert 1'''. This arrangement is of a particularly simple design, but implements a dispensing assembly with an internal passageway and an internal threaded sleeve adapted to receive the threaded neck C of the bottle F by screwing.

The present invention provides a fluid product refill with a flexible pouch including a dispensing assembly that can be easily connected to the threaded neck of a bottle.
