Description

[0001] The present invention relates to a fluid product reservoir comprising a container defining a neck and a mounting part mounted on the neck. The mounting part forms a basket disposed at the neck and a dip tube which extends from the basket into the container. The dip tube is initially sealed by a sealing member, which may be in the form of a membrane to be pierced, a plug to be dislodged, etc. This type of reservoir is often used as a refill on which a top assembly comprising a pump or a valve is removably mounted, so that it can be removed from a reservoir to be refitted on a new reservoir.

[0002] The preferred fields of application of the present invention are those of cosmetics, food, household products and even pharmacy.

[0003] In the prior art, documents US10226782, US2020156833 and WO2018115306 are already known, which describe tanks of this type, with a dip tube initially closed by a sealing member. In document US10226782, the dispensing member is specially designed to release the sealing member, which will fall to the bottom of the container. The dispensing member will also pierce a membrane to form a venting passage for the container. In document WO2018115306, it is a tube that pierces a film. In both cases, it is an external member that is used to clear the passage of the dip tube. There is therefore a risk of incorrect handling or adaptation during the connection operation.

[0004] The present invention aims to overcome this problem related to the clearance of the dip tube. Another aim of the invention is to be able to use a standard dispensing member to cause the piercing or movement of a sealing member in the dip tube.

[0005] To this end, the present invention proposes a fluid product reservoir which further comprises an insert arranged in the basket and comprising a piercing element movable between an initial position in which the sealing member is closing and a final position in which the sealing member is moved into a state passing through the piercing element. Thus, it is no longer the dispensing member which pierces or dislodges the sealing member, but a part which is an integral part of the reservoir, since it is initially inserted into the basket of the mounting part. This insert is certainly moved by the dispensing member, but it is not the dispensing member which acts directly on the sealing member. This insert could be considered as a thrust transmission element which will also carry out the piercing or dislodgement of the sealing member. Thus, the insert is an integral part of the reservoir and not of the dispensing member.

[0006] According to the invention, the insert is mainly housed inside the basket and comprises a sleeve forming a housing for receiving the fitting of an inlet sleeve of a dispensing member (pump or valve), the sleeve being integral in movement with the piercing element. The housing and the piercing element constitute a sort of extension for the inlet sleeve, but this extension is part of the reservoir and not of the dispensing member.

[0007] According to an advantageous characteristic of the invention, the insert is integral with the basket in the initial position and in the final position. It can even be said that the insert is permanently integral with the basket, even if its piercing element is moved in the basket by the inlet sleeve of the dispensing member which is received in the receiving housing.

[0008] According to one embodiment, the basket and the insert may delimit between them a buffer space, which advantageously communicates with the outside in the final position of the insert and which advantageously communicates with the container through a one-way valve or a filter allowing air from the buffer space to enter the container. Furthermore, the buffer space may be isolated from the outside in the initial position. Thus, in the event of fluid product leaking through the valve or filter, it will be stored in the buffer space and will not contaminate either the user or even the dispensing member.

[0009] According to another aspect of the invention, the mounting part may comprise a fixing sleeve for mounting a dispensing member, such as a pump, comprising an inlet sleeve and a fixing ring adapted to engage with the fixing sleeve. This fixing sleeve is preferably threaded, as is the fixing ring, so that the displacement or piercing of the sealing member by the piercing element and / or the fitting of the inlet sleeve into the receiving housing takes place when the ring is screwed onto the sleeve.

[0010] According to a practical embodiment, the insert can be slidably mounted in the basket between the initial and final positions, the insert being advantageously in sealed contact with the basket in the initial position and advantageously in non-sealing contact with the basket in the final position. More specifically, the insert can comprise a sliding lip which is in sealed contact with a cylindrical wall of the basket in the initial position, can then slide in a sealed manner in the cylindrical wall, this cylindrical wall being able to form a relief (hollow or protruding) which will generate a sealing defect in the final position.

[0011] According to a practical embodiment, the insert may comprise a deformable membrane connecting the piercing element to a fixed edge secured to the basket, the insert being advantageously made in a single piece with the mounting part. The basket and the insert may be molded flat side by side, being connected by a hinge or a flexible connection: the insert is then folded down by pivoting into the basket. Preferably, the fixed edge of the insert is snapped onto the basket.

[0012] In both embodiments, the insert can be snapped into the basket in the final position. A friction lock can also perform the function of maintaining the snap in the final position. The aim is to prevent the insert from being removed from the basket when the dispensing member is separated from the reservoir: the insert must remain in place in the basket.

[0013] Advantageously, the insert may form an inlet well, which is sealed by a tear-off or pierceable seal, which advantageously extends to an upper edge of the basket. The inlet well may be surrounded by a flat annular area which is flush with the upper edge of the basket, so that the seal may lie flat on both the flat annular area and the upper edge. This seal does not need to be watertight, since the reservoir is already sealed by the sealing member. The seal must simply prevent dirt from entering the insert through its inlet well. It also gives an indication to the user that the reservoir has never been opened. The seal may remain in place, then pierced, or conversely may be removed by the user.

[0014] According to a practical aspect, the sealing member is a pierceable membrane which remains connected to the dip tube once pierced, the dip tube advantageously forming an internal shoulder under which the pierceable membrane, once pierced, is housed. Preferably, the pierceable membrane is made in a single piece with the rest of the mounting part.

[0015] Advantageously, an upper extension of the basket may form a threaded sleeve which projects beyond a fixing cup, which engages, advantageously snap-fit, around the neck of the container. Thus, the container may be extremely simple, for example in the form of a blown can with a neck provided with an external snap-fit ​​profile.

[0016] The present invention also defines a fluid product dispenser comprising a dispensing member, such as a pump, comprising an inlet sleeve and a fixing ring for fixing the dispensing member to a fluid product reservoir as defined above comprising a receiving housing for the inlet sleeve.

[0017] Advantageously, the mounting part may form a fixing sleeve, the fixing ring engaging, advantageously threaded, with the fixing sleeve on an axial fixing stroke, the engagement of the inlet sleeve in the receiving housing and / or the displacement of the sealing member by the piercing element advantageously occurring during the axial fixing stroke. The pump or valve is therefore in fluid communication through the insert and the dip tube, the sealing member of which has been neutralized by the displacement of the insert under the stress of the inlet sleeve.

[0018] Preferably, the sealing member may be a pierceable membrane, the fixing ring may be a screw-on fixing ring, the piercing element may be a section of beveled tube, the screw-on fixing ring, when screwed onto the threaded sleeve, moves the inlet sleeve and the insert over an axial screwing stroke, the section of beveled tube advantageously piercing the pierceable membrane during this axial screwing stroke.

[0019] The spirit of the invention lies in the fact of integrating piercing or "unsealing" means into the tank, so as not to need to adapt the dispensing member, which can therefore be standard: its only function being to push, and no longer to pierce or intervene directly on the sealing means. The removable fixing by screwing (or bayonet) of the dispensing member on the tank of the invention makes it possible to multiply the forces to facilitate the fitting of the inlet sleeve into the receiving housing and / or the piercing of the sealing member.

[0020] An important advantage of the invention is that the dispensing member, and more particularly its inlet sleeve, can be separated from the tank in a perfectly clean state, given that only the inside of the inlet sleeve is in contact with the fluid product: the outside of the sleeve is embedded in the housing of the insert. And even in the event of a leak through the valve or the filter, the fluid product remains in the buffer space. As a result, the dispensing member can be removed from an empty tank and refitted on a new, filled tank without the risk of depositing fluid product anywhere.

[0021] It should be noted that the fact of producing the threaded sleeve and the sealing member (pierceable membrane) in a single part, namely the mounting part, is a feature that could be implemented regardless of whether the basket contains an insert. This feature is advantageous in two ways. Firstly, the axial distance between the thread of the tank and the pierceable membrane is constant: this is not the case in document US10226782. Piercing of the membrane during the screwing stroke is therefore easier to guarantee. Secondly, the container can be produced more simply without an external thread. Protection could therefore be sought for a tank with a mounting part forming a threaded sleeve and a sealing member.

[0022] The invention will now be more fully described with reference to the accompanying drawings, giving, by way of non-limiting examples, two embodiments of the invention.

[0023] In the figures: There figure 1 is a vertical cross-sectional view through a fluid product reservoir according to a first embodiment of the invention, The figure 2 represents the upper part of the figure 1 with a distribution organ being attached to the tank, The figure 3 is a view similar to that of the figure 2 showing the dispensing member being screwed onto the reservoir of the invention, The figure 4 is a cutaway perspective view showing the dispensing member in the final mounting position on the reservoir of the invention, The figures 5a et 5b are cutaway perspective views showing the operation of drilling the sealing member, The figure 6 is a perspective view of a mounting part and an insert according to a second embodiment of the invention, The figures 7a, 7b et 7c are schematic vertical cross-sectional views through a tank and a dispensing member to be mounted on the tank, and The figure 8 is a greatly enlarged view showing the drilling of the sealing member in the final assembly position.

[0024] We will first refer to the figure 1 to generally describe the overall design of a fluid product reservoir according to the first embodiment of the invention. The reservoir R comprises a container R1 comprising a neck R2 which can be provided externally with one or more attachment profile(s) R3, preferably in the form of snap-fastening profiles. The container R1 can very simply be produced in the form of a can. It can be obtained using a blow-molding process, given that the design of its neck R2 is very simple.

[0025] The tank R also comprises a mounting part 1 which is preferably made by injection molding of suitable plastic material. The mounting part is preferably a single piece, with the exception of its single directional valve 13, as will be seen below. This mounting part 1 comprises a basket 11, a dip tube 12, a one-way valve 13 and a fixing cup 14. The basket 11, the dip tube 12 and the cup 14 can be made as a single piece. Separate embodiments are however conceivable. In particular, the dip tube 12 could be mounted on the basket 11. The dip tube 12 is connected to the lower end of the basket 11 and extends into the container R1 to near its bottom. The dip tube 12 can be rigid or flexible. In its initial state, as shown in the figure 1 , the communication between the basket 11 and the dip tube 12 is cut off by a sealing member 121, which is here arranged inside the dip tube 12, close to the basket 11. This sealing member 121 is here in the form of a pierceable membrane which is made in one piece with the rest of the mounting part 1. Instead of this pierceable membrane, it would also be possible to use an added cover or a part capable of being moved between a closing state and a passing state. The sealing member 121 is here made inside the dip tube 12, but it could also be arranged at the basket 11. The function of this sealing member is to cut off the communication between the inlet of the basket 11 and the outlet of the dip tube 12. It can be seen on the figure 1 that the dip tube 12 extends inside the basket 11 in the form of a tubular section 122.

[0026] The basket 11 is arranged at the neck R2: it extends downwards inside the container R1 and also upwards, forming a sleeve 113 which is threaded externally. It can be noted that the basket 11 has an overall cylindrical shape with its bottom partially closed and its upper end open.

[0027] The fixing cup 14 extends radially outward from the basket 11 to engage, advantageously snap-fit, with the neck R2 of the container R1. A screw fixing may be considered, but is not preferable.

[0028] The basket 11 also defines a seat for the one-way valve 13 which only allows the entry of outside air into the container R1. Any exit of fluid product from the container R1 through this valve 13 is prohibited.

[0029] The reservoir R also comprises an insert 2 which is mainly housed inside the basket 11. The insert 2 generally has a funnel shape, with a passage section which decreases from top to bottom. The insert 2 comprises a piercing element 21 which is formed at the lower end of a tube 20 which is partially engaged inside the dip tube 12, or more precisely its tubular section 122. The piercing element 21 may be in the form of a beveled tube section, and advantageously sharpened. Internally, the tube 20 defines a passage conduit 22. In the initial position, as shown in the figure 1 , the piercing element 21 is arranged close to or in contact with the sealing member 121 which closes the dip tube 12. Upstream of the tubing 20, the insert 2 forms a sleeve 23 which internally defines a receiving housing 24, the function of which will be given below. It can be noted that the sleeve 23 comprises a frustoconical upper part and a cylindrical lower part. The receiving housing 24 communicates directly with the passage conduit 22. Upstream of the sleeve 23, the insert 2 forms a crown 25 which is engaged inside the basket 11, at the level of its threaded sleeve 113. This crown 25 defines an inlet well 26 which communicates directly with the receiving housing 24. It can be noted that the upper edge of the crown 25 is advantageously arranged flush with the upper edge of the threaded sleeve 113.Optionally, a seal 28 can be glued to both the upper edge of the crown 25 and the upper edge of the sleeve 113, so as to prevent any introduction of foreign bodies or particles inside the insert 2. The seal 28 does not need to be fixed in a sealed manner, given that the interior of the container R1 is already isolated from the outside by the sealing member 121.

[0030] It can be noted that a buffer space 10 is formed between the basket 11 and the insert 2. In the initial position, as shown in the figure 1 , this buffer space 10 cannot communicate with the outside, due to the sealed contact of the crown 25 with the sleeve 113, and moreover the sealed application of the cover 28. On the other hand, the buffer space 10 can communicate with the interior of the container R1 through the one-way valve 13, as soon as a depression is formed inside the container R1. The air contained in the buffer space 10 can thus penetrate inside the tank R1.

[0031] It may be noted that the mounting part 1 forms both the sealing member 121 and the threaded sleeve 113, so that the mutual arrangement of these two elements is fixed and precise. This is a characteristic which is independent of the fact that the basket 11 contains an insert 2.

[0032] On the figure 2 , we see the tank of the figure 1 , which is still in its initial position, with its sealing member 121 intact. We also see a distribution member P, which is only shown very schematically. This distribution member P, which can integrate a pump or a valve, also comprises an inlet sleeve P1, a fixing ring P2 and a pusher P3. The inlet sleeve P1 defines an internal conduit which communicates with the pump or valve chamber, generally through an inlet flap (not shown). The inlet sleeve P1 is of a completely conventional type adapted to receive a conventional dip tube by fitting it around or inside the inlet sleeve P1. As for the fixing member P2, it preferably comprises an internal thread P21 whose pitch corresponds to that of the threaded sleeve 113 of the mounting part 1 of the tank according to the invention.It can be said that the dispensing member P does not include any inventive feature, and that it is therefore not critical to the invention.

[0033] It can be seen that the dispensing member P has already been attached to the reservoir of the invention, with its inlet sleeve P1 which has already penetrated inside the inlet well 26 of the crown 25 by tearing or piercing the cover 28. As a variant, the cover 28 can be removed before engaging the sleeve P1 inside the insert 2.

[0034] Given that the figure 2 represents the upper part of the tank in an enlarged manner, more details can be seen there. In particular, it can be seen that the fixing cup 14 comprises an external skirt 141 which forms one or more snap-in teeth 144 intended to cooperate with the profiles R3 of the neck R2. The cup 14 also defines a self-sealing lip 142 intended to come into sealed contact with the internal wall of the neck R2 to provide a seal. Furthermore, the threads 114 formed on the external wall of the fixing sleeve 113 which extends the basket 11 outwards can be clearly seen. The internal wall of the sleeve 113 is perfectly cylindrical and the crown 25 forms an annular sealing lip 251 which comes into sealed sliding contact inside the sleeve 113. However, it can be noted that the internal cylindrical wall 111 of the basket 11 forms one or more vertical rib(s) 1111 which thus break the cylindricity of the basket.It is then easily understood that the sliding of the insert 2 downwards will bring the annular sealing lip 251 to the level of this or these rib(s) 1111 so as to create a sealing defect. It can also be noted that the tubing 20 externally defines a snap-on bead 211 intended to engage inside a snap-on groove 123 formed inside the cylindrical section 122, which forms an extension of the dip tube 12 inside the basket 11.

[0035] In this initial position ( figure 2 ), the interior of the container R1 is isolated from the exterior by the sealing member 121, the one-way valve 13, the annular sealing lip 251 and the lip 142. The buffer space 10 is then isolated both from the exterior and from the container R1. The interior of the insert 2 is closed upstream by the cover 28 and downstream by the sealing member 121.

[0036] On the figure 3 , we see that the internal thread P21 of the fixing ring P2 of the distribution member P has just come into engagement with the external thread 114 of the sleeve 113. The insert 2 is still in its initial state, held in position by the friction of the lip 251 in the barrel 111 of the basket 11 and its tubing 20 inside the tubular section 122. This start of threaded engagement has however allowed the inlet sleeve P1 to be fitted inside the receiving housing 24 formed by the cuff 23. The sleeve P1 is then already in its final mounting position inside the receiving housing 24. The sealing member 121 is still intact, since the piercing element 21 is still arranged at a distance.

[0037] On the figure 4 , it can be seen that the fixing ring P2 is in its final screwing position with its thread P21 in final engagement with the thread 114 of the sleeve 113. The insert 2 has been moved by sliding inside the basket 11, which results in a corresponding movement of its tubing 20 inside the tubular section 122 and the dip tube 12, leading to the piercing of the sealing member 121 by the piercing element 21. The lip 251 of the crown 25 is then arranged at the height of the rib(s) 1111, thus creating a sealing defect. The snap-in rib 211 is housed inside its corresponding snap-in rib 123. The final mounting position is then reached. The buffer space 10 allows the interior of the tank R1 to communicate with the exterior through the one-way valve 13 and the sealing defect between the lip 251 and the rib 1111. The path of the incoming air is represented by a bubble path.

[0038] It can be noted that the movement of the insert 2 inside the basket 11 takes place during the screwing phase of the ring P2 onto the sleeve 113. In other words, the axial movement of the insert 2 corresponds substantially to the axial screwing stroke of the dispensing member P onto the reservoir R. Preferably, the piercing of the sealing member 21 by the piercing element 21 takes place during this axial screwing stroke. Advantageously, the fitting of the inlet sleeve P1 into the receiving housing 24 also takes place during this axial screwing stroke.

[0039] Without departing from the scope of the invention, other fixing means can be imagined for fixing the dispensing member P to the reservoir R. Instead of the threads P21 and 114, other types of profiles can be imagined allowing fixing, for example, by bayonet or snap-fastening. In this case, there is always an axial fixing stroke, during which it is preferable for the drilling and / or fitting to take place.

[0040] Referring to the figures 5a et 5b , which are greatly enlarged views, it can be seen how the sealing member 121 is rendered inoperative by the piercing element 21. It can be seen that the tubing 20 ends with a section of tube that is both beveled and thinned, forming the piercing element 21. The dip tube 12, the section of which is preferably constant over most of its length, here comprises an inlet section 125 of reduced passage, thus forming a shoulder 124 oriented downwards. The sealing member 121 is in the form of a membrane which is connected to this shoulder 124. The membrane 121 comprises a central portion 1211 of constant thickness and a thinned peripheral edge 1212 which is connected to the shoulder 124.Thus, when the tubing 20 is moved downwards under the stress of the inlet sleeve P1, the leading edge of the piercing element 21 will break the thinned edge 1212 of the membrane 121 progressively, given the beveled configuration of the piercing element 21. On the . figure 5a , we see that the thinned edge 1212 is already partially cut. On the figure 5b , we see the tubing 20 in its final position, with its piercing element 21 which has penetrated inside the dip tube 12. The thinned edge 1212 has been completely broken and there remains only a small bridge of material to connect the membrane 121 to the shoulder 124. We then easily understand the function of this shoulder 124, which makes it possible to house the membrane 121 between the piercing element 21 and the dip tube 12. Thus, the membrane 121 does not detach from the rest of the mounting part, and does not fall to the bottom of the dip tube 12. This avoids any risk of blockage or malfunction linked to the floating of the membrane 121.

[0041] We will now refer to the figures 6 à 8 to describe a second embodiment of the invention. On the figure 6 , we see a mounting part 1' and an insert 2' which are made in a single piece, for example by injection molding of suitable plastic material. The mounting part 1' and the insert 2' are connected by a tab 253 and a hinge 254. These two parts are molded flat as shown in the figure 6 . The mounting part 1' also comprises a basket 11', a dip tube 12' and a fixing cup 14'. The basket 11' comprises an upper annular area 114' forming a re-entrant rim 115. The basket also comprises a unidirectional filter 13'. The insert 2' also comprises a piercing element 21', a receiving housing 23' and an outer ring 25' forming a deformable flexible membrane 251'. The ring 25' is bordered by a fixed annular flange 252. It is then easily understood that it is possible to fold the insert 2' onto the mounting part 1' so as to cause the piercing element 21' and receiving housing 23' to penetrate inside the basket 11'. In doing so, the annular flat flange 252 will be housed inside the retracting rim 115 so that the crown 25' comes flush with the annular area 114' of the cup 14'.The fixed annular flange 252 may be snapped, preferably in a non-sealing manner, into the retracted rim 115. This folded configuration is shown in the . figure 7a . The deformable membrane 251' is in its rest state and the piercing element 21' is away from the sealing member 121, which may be similar or identical to that of the first embodiment. A buffer space 10' is also formed between the basket 11' and the insert 2'. The fixing cup 14' externally forms a threaded fixing sleeve 113'.

[0042] As before, the first step is to fit the inlet sleeve P1 inside the receiving housing 23'. This is shown in the figure 7b . Insert 2' is still in its initial state with the sealing member intact.

[0043] The fixing of the distribution member P' on the reservoir R' has the effect of moving the inlet sleeve P1, which leads to a deformation of the membrane 251' and a movement of the piercing element 21' which then releases the sealing member 121, as shown in an enlarged manner in the figure 8 .

[0044] Thus, in this second embodiment, the insert 2' does not slide inside the basket 11', but is however moved by deformation of its membrane 251'.

[0045] Although made in a single piece, it is also possible to make the insert 2' separately and attach it to the inside of the basket 11'. In this case, the tab 253 and the hinge 254 are removed.

[0046] Just as in the first embodiment, it is preferable that the piercing of the sealing member 121 and / or the fitting of the inlet sleeve P1 into the receiving housing 23' takes place during the axial stroke of fixing the dispensing member P' on the reservoir R'.

[0047] In both embodiments, as well as in their possible variants, an insert 2, 2' is an integral part of the reservoir of the invention, in the sense that it is already integrated into the reservoir, well before attaching the dispensing member to the reservoir. The movement of the insert under the stress of the inlet sleeve to pierce or dislodge or release the dip tube is an essential characteristic of the invention. The insert is permanently secured to the basket, even if its piercing element is movable in the basket. The formation of a buffer space 10, 10' is also advantageous, because it makes it possible to collect and trap any fluid product which could leak through the one-way valve 13, which could also be replaced by a one-way filter.The insert also makes it possible to maintain the dispensing member in a very satisfactory state of cleanliness, which is particularly advantageous, since the reservoir of the invention is mainly intended to serve as a refill, which implies that the dispensing member has to be removed from an empty reservoir and then refitted onto a full reservoir.
