Description

Technical Field

[0001] This invention relates to a fluid reservoir comprising a container defining a neck and a mounting member mounted on the neck. The mounting member forms a basket portion disposed at the neck and a draw tube extending from the basket portion into the container. The draw tube is initially sealed by a sealing member, which may be in the form of a puncturable membrane, a plug to be removed, etc. This type of reservoir is commonly used as a refiller, with a top assembly including a pump or valve detachably mounted on it so that it can be removed from the reservoir for reinstallation in a new reservoir.

[0002] The preferred application areas of this invention are skin care cosmetics, food, household products, or pharmaceuticals. Background Technology

[0003] In the prior art, documents US10226782 and WO2018115306 are known, describing this type of reservoir in which the draw tube is initially sealed by a sealing member. In US10226782, the dispensing member is specifically designed to clear the sealing member, which will fall to the bottom of the container. The dispensing member also breaks the membrane to form a ventilation channel for the container. In WO2018115306, it is the tube that breaks the membrane. In both cases, an external member is used to release the channel of the draw tube. Therefore, there is a risk of improper handling or adjustment during connection operations. Summary of the Invention

[0004] The object of this invention is to overcome this problem associated with the release of the extraction tube. Another object of this invention is to enable the use of standard dispensing components to create the breaking or movement of the sealing components in the extraction tube.

[0005] To this end, the present invention proposes a fluid reservoir, which further includes an insert disposed in a housing. The insert includes a piercing element movable between an initial and a final position where a sealing member is closed, in which the sealing member is moved by the piercing element to an open position. Therefore, it is no longer a dispensing member, but a component forming an integral part of the reservoir, that breaks or removes the sealing member, since this component is initially inserted into the housing of the mounting component. The insert is moved by the dispensing member, but it is not the dispensing member that acts directly on the sealing member. The insert can be considered a thrust-transmitting element, which also performs the breaking or removal of the sealing member. Therefore, the insert is an integral part of the reservoir, not an integral part of the dispensing member.

[0006] According to the invention, the insert forms a receiving slot for the inlet sleeve of a dispensing member (pump or valve), the receiving slot being integrally movable with a puncture element. The slot and the puncture element constitute an extension for the inlet sleeve, but this extension is a component of the reservoir, not a component of the dispensing member.

[0007] According to an advantageous feature of the invention, the insert is fixedly connected to the basket portion in both the initial and final positions. Furthermore, the insert is permanently fixed to the basket portion even if its piercing element is moved within the basket portion via the inlet sleeve received in the receiving slot by the dispensing member.

[0008] According to one embodiment, a buffer space can be defined between the basket and the insert, the buffer space advantageously communicating with the outside at the final position of the insert, and advantageously communicating with the container via a one-way valve or filter that allows air to enter the container from the buffer space. Alternatively, the buffer space can be isolated from the outside in its initial position. Therefore, in the event of fluid leakage through the valve or filter, the fluid will be stored in the buffer space, preventing contamination of the user or even the dispensing components.

[0009] According to another aspect of the invention, the mounting component may include a retaining sleeve for mounting a dispensing member, such as a pump, the dispensing member comprising an inlet sleeve and a retaining ring adapted to engage with the retaining sleeve. The retaining sleeve is preferably threaded, like the retaining ring, such that when the ring is tightened onto the sleeve, a puncturing element moves or breaks the sealing member and / or the inlet sleeve into the receiving slot.

[0010] According to one embodiment, the insert can be mounted to slide within the basket portion between an initial position and a final position. The insert advantageously provides a sealing contact with the basket portion in the initial position and an unsealed contact in the final position. More specifically, the insert may include a sliding lip that provides a sealing contact with a cylindrical wall of the basket portion in the initial position, and can then slide in a sealing manner within the cylindrical wall, which is capable of forming an embossed shape that will create a sealing gap (recessed or protruding) in the final position.

[0011] According to one embodiment, the insert may include a deformable membrane that connects the puncture element to a fixed edge fixed to the basket portion. The insert is advantageously manufactured as a single unit with the mounting component. The basket portion and the insert can be connected by hinges or flexible connectors and molded side-by-side; the insert is then folded down into the basket portion by pivoting. Preferably, the fixed edge of the insert snaps onto the basket portion.

[0012] In both embodiments, the insert can be snapped into the basket in its final position. Friction locking can also achieve the function of keeping the snap-fit ​​in the final position. The purpose is to prevent the insert from moving out of the basket when the dispensing member is separated from the reservoir: the insert must remain in place within the basket.

[0013] Advantageously, the insert can form an inlet well, which is closed by a tear-off or puncture-resistant cap that advantageously extends to the upper edge of the basket. The inlet well can be surrounded by a planar annular region flush with the upper edge of the basket, such that the cap can extend flatly on both the planar annular region and the upper edge. The cap does not need to be airtight, as the reservoir is already sealed by a sealing member. The cap should simply prevent dirt from entering the insert through its inlet well. It also indicates to the user that the reservoir has never been opened. The cap can remain in place and then be punctured, or conversely, the user can remove the cap.

[0014] According to one practical aspect, the sealing member is a puncture-resistant membrane that, once punctured, remains connected to the suction tube, which advantageously forms an inner shoulder under which the puncture-resistant membrane is accommodated once punctured. Preferably, the puncture-resistant membrane is made as a single unit with the rest of the mounting component.

[0015] Advantageously, the upper extension of the basket portion can form a threaded sleeve that protrudes beyond the fixed cup portion, which engages and snaps into the neck of the container. Thus, the container can be very simple, for example, in the form of a blown can with a neck having an external snap-fit ​​profile.

[0016] The present invention also defines a fluid distributor comprising a dispensing member such as a pump, the dispensing member including an inlet sleeve and a retaining ring for securing the dispensing member to a fluid reservoir as defined above, the fluid reservoir including a receiving slot for the inlet sleeve.

[0017] Advantageously, the mounting components can form a fixed sleeve, with the retaining ring engaging the fixed sleeve during the axial fixed stroke, advantageously threadedly, during which the inlet sleeve engages in the receiving slot and / or the sealing member is moved by the puncturing element. Thus, the pump or valve communicates with fluid through the insert and the suction pipe, and the sealing member of the suction pipe is rendered ineffective by the movement of the insert actuated by the inlet sleeve.

[0018] Preferably, the sealing member can be a puncturable membrane, the retaining ring can be a retaining ring to be tightened, and the puncturing element can be a beveled pipe section. When the retaining ring to be tightened is tightened onto the threaded sleeve, it causes the inlet sleeve and the insert to move in the axial tightening stroke, which advantageously breaks the puncturable membrane during the axial tightening stroke.

[0019] The concept of this invention lies in the fact that the perforation or "unsealing" device is integrated into the reservoir, thus eliminating the need to adjust the dispensing member. Therefore, the dispensing member can be standard, its sole function being to actuate the sealing device rather than break it or act directly on it. The dispensing member is detachably secured to the reservoir of this invention by threading (or snapping), allowing for reduced force to facilitate the fitting of the inlet sleeve into the receiving slot and / or to facilitate the breaking of the sealing member.

[0020] A key advantage of this invention is that the dispensing member, particularly its inlet sleeve, can be separated from the reservoir in a perfectly clean state because only the interior of the inlet sleeve comes into contact with the fluid; the exterior of the sleeve is embedded in the slot of the insert. Even in the event of a leak through a valve or filter, the fluid remains in the buffer space. Therefore, the dispensing member can be removed from an empty reservoir and reinstalled into a newly filled reservoir without the risk of fluid sedimentation anywhere.

[0021] It should be noted that the fact that the threaded sleeve and the sealing member (puncturable membrane) are made into a single, identical component, i.e., the mounting component, is a feature that can be achieved independently of the fact that the container accommodates the insert. This feature is advantageous in two ways. First, the axial distance between the reservoir thread and the puncturable membrane is constant: this is not the case in document US 10226782. Therefore, it is easier to ensure that the membrane breaks during the tightening stroke. Second, the container can be made simpler without external threads. Therefore, protection can be sought for reservoirs with mounting components forming the threaded sleeve and the sealing member. Attached Figure Description

[0032] First, refer to Figure 1 The general design of a fluid reservoir according to a first embodiment of the present invention will be described in general. The reservoir R includes a container R1, the container R1 including a neck R2, the neck R2 possibly having one or more externally provided fastening profiles R3, preferably in the form of snap-fit ​​profiles. The container R1 can be very easily manufactured into the form of a can. It can be obtained by a blow molding process because the design of its neck R2 is very simple.

[0033] The container R also includes a mounting component 1, which is preferably injection molded from a suitable plastic material. As will be seen below, the mounting component is preferably a single unit except for its individual directional valve 13. The mounting component 1 includes a basket portion 11, a draw tube 12, a one-way valve 13, and a fixed cup portion 14. The basket portion 11, the draw tube 12, and the cup portion 14 can be made as a single unit. However, it is also possible for them to be made separately. In particular, the draw tube 12 can be mounted on the basket portion 11. The draw tube 12 is connected to the lower end of the basket portion 11 and extends into the container R1 until near the bottom of the container. The draw tube 12 can be rigid or flexible. In its initial state, as... Figure 1 As shown, the communication between the basket section 11 and the suction tube 12 is severed by a sealing member 121, which is positioned inside the suction tube 12 near the basket section 11. This sealing member 121 is in the form of a puncture-resistant membrane, which is integrally formed with the rest of the mounting component 1. Alternatively, an attached cap or a component movable between a closed and open state can be used instead of this puncture-resistant membrane. While the sealing member 121 is implemented inside the suction tube 12, it can also be positioned at the basket section 11. The function of this sealing member is to sever the communication between the inlet of the basket section 11 and the outlet of the suction tube 12. Figure 1 As can be seen, the suction tube 12 extends into the basket section 11 in the form of a tubular section 122.

[0034] The basket portion 11 is arranged at the neck R2: the basket portion 11 extends downward and upward within the container R1, forming a threaded sleeve 113 on the outside. It can be noted that the basket portion 11 has an overall cylindrical shape, with its bottom partially closed and its top open.

[0035] The retaining cup portion 14 extends radially outward from the basket portion 11 to engage and advantageously snap into the neck R2 of the container R1. Tightening may be considered, but this is not preferred.

[0036] The basket portion 11 also defines a valve seat for a one-way valve 13, which allows only external air to enter the container R1. Fluid outflow from the container R1 through this valve 13 is prohibited.

[0037] The reservoir R also includes an insert 2, which is primarily housed within the basket portion 11. The insert 2 is generally funnel-shaped, with a channel cross-section that decreases from top to bottom. The insert 2 includes a piercing element 21 formed at the lower end of the tube 20, which partially engages within the extraction tube 12, or more precisely, within its tubular section 122. The piercing element 21 may be in the form of an obliquely shaped tube section, advantageously sharp. Internally, the tube 20 defines the passage through the conduit 22. In the initial position, as... Figure 1 As shown, the puncture element 21 is arranged near or in contact with the sealing member 121 of the sealed suction tube 12. Upstream of the tube 20, the insert 2 forms a cylindrical portion 23, which internally defines a receiving slot 24, the function of which will be described below. Note that the cylindrical portion 23 includes a truncated conical upper portion and a cylindrical lower portion. The receiving slot 24 communicates directly with the tube 22. Upstream of the cylindrical portion 23, the insert 2 forms an annular crown 25, which engages within the basket portion 11 at a threaded sleeve 113. This annular crown 25 defines an inlet well portion 26 that communicates directly with the receiving slot 24. Note that the upper edge of the annular crown 25 is advantageously flush with the upper edge of the threaded sleeve 113. Optionally, a cap 28 may be simultaneously adhered to the upper edge of the annular crown 25 and the upper edge of the sleeve 113 to prevent the introduction of foreign objects or particles into the insert 2. The lid 28 does not need to be secured in a sealed manner because the interior of container R1 is already isolated from the outside by the sealing member 121.

[0038] It can be noted that a buffer space 10 is formed between the basket portion 11 and the insert 2. In the initial position, as... Figure 1 As shown, due to the sealing contact between the annular cap 25 and the sleeve 113, as well as the sealing effect of the additional cover 28, the buffer space 10 cannot communicate with the outside. Conversely, once a negative pressure is formed inside the container R1, the buffer space 10 can communicate with the interior of the container R1 through the one-way valve 13. Therefore, air contained in the buffer space 10 can enter the interior of the storage container R1.

[0039] It can be noted that the mounting component 1 simultaneously forms both the sealing member 121 and the threaded sleeve 113, ensuring that the relative arrangement of these two elements is fixed and precise. This still relates to a feature independent of the fact that the basket portion 11 accommodates the insert 2.

[0040] exist Figure 2 It can be seen in Figure 1 The reservoir remains in its initial position, with its sealing member 121 intact. The dispensing member P can also be seen, shown only schematically. This dispensing member P may integrate a pump or valve and also includes an inlet sleeve P1, a retaining ring P2, and a pusher P3. The inlet sleeve P1 defines an internal conduit that typically communicates with a pump or valve chamber via an inlet valve (not shown). The inlet sleeve P1 is of a completely conventional type, suitable for receiving a conventional draw tube by surrounding or fitting within the inlet sleeve P1. As for the retaining member P2, it preferably includes an internal thread P21, the pitch of which corresponds to the pitch of the threaded sleeve 113 of the mounting component 1 of the reservoir according to the invention. It can be said that the dispensing member P does not contain any inventive features and is therefore not critical to the invention.

[0041] As can be seen, the dispensing member P has been installed on the reservoir of the present invention, and its inlet sleeve P1 has been inserted into the inlet well portion 26 of the annular crown 25 by tearing or piercing the cap 28. In a variant, the cap 28 can be removed before the sleeve P1 is engaged into the insert 2.

[0042] because Figure 2 The upper part of the reservoir is shown in magnified view, allowing for a greater view of detail. Specifically, it can be seen that the retaining cup portion 14 includes an outer skirt portion 141 forming one or more snap-fit ​​teeth 144 for engaging with the profile R3 of the neck R2. The cup portion 14 also defines a self-engaging lip 142 for sealing contact with the inner wall of the neck R2 to achieve a seal therein. Furthermore, threads 114 formed on the outer wall of the retaining sleeve 113, which extends outwardly into the basket portion 11, are clearly visible. The inner wall of the sleeve 113 is perfectly cylindrical, and an annular crown 25 forms an annular sealing lip 255 that seals a sliding contact within the sleeve 113. However, it can be noted that the inner cylindrical wall 111 of the basket portion 11 is formed with one or more vertical ribs 1111, thereby disrupting the cylindricality of the basket portion. It is therefore easy to understand that the downward sliding of the insert 2 will bring the annular sealing lip 251 to the ribs 1111 or these ribs, thus creating a seal gap. It can also be noted that the tube 20 defines a snap-fit ​​flange 211 on the outside, which is used to engage a snap-fit ​​groove 123 formed in the cylindrical section 122, which forms an extension of the suction tube 12 within the basket section 11.

[0043] At the initial position ( Figure 2 The interior of container R1 is isolated from the outside by sealing member 121, one-way valve 13, annular sealing lip 251, and lip 142. Buffer space 10 is thus isolated from both the outside and container R1. The interior of insert 2 is closed upstream by cap 28 and downstream by sealing member 121.

[0044] Figure 3 As can be seen, the internal thread P21 of the retaining ring P2 of the dispensing member P has just engaged with the external thread 114 of the sleeve 113. The insert 2 is still in its initial state, held in place by the friction of the lip 251 in the cylinder 111 of the basket portion 11 and its tube 20 in the tubular section 122. However, the initiation of this threaded engagement has already allowed the inlet sleeve P1 to be fitted into the receiving slot 24 formed by the cylinder portion 23. The sleeve P1 is now in its final installation position in the receiving slot 24. The sealing member 121 remains intact because the puncture element 21 is still positioned away from the arrangement.

[0045] exist Figure 4 As can be seen, the retaining ring P2 is in its final tightened position, with its thread P21 finally engaging with the thread 114 of the sleeve 113. The insert 2 moves by sliding within the housing portion 11, which manifests as corresponding movement of its tube 20 within the tubular section 122 and the suction tube 12, resulting in the sealing member 121 being broken open by the puncturing element 21. The lip 251 of the ring crown 25 is then positioned at the height of the rib 1111, creating a seal gap. The snap rib 211 is accommodated within its corresponding snap rib 123. Thus, the final installation position is reached. The buffer space 10 allows the interior of the reservoir R1 to communicate with the outside through the one-way valve 13 and the seal gap between the lip 251 and the rib 1111. The path for air entry is represented by the bubble path.

[0046] It can be noted that the movement of the insert 2 within the basket 11 occurs during the stage when the ring P2 is tightened onto the sleeve 113. In other words, the axial movement of the insert 2 substantially corresponds to the axial tightening stroke of the dispensing member P on the reservoir R. Preferably, during this axial tightening stroke, the sealing member 21 is broken open by the piercing element 21. Advantageously, during this axial tightening stroke, the inlet sleeve P1 also engages in the receiving slot 24.

[0047] Without departing from the scope of the invention, other securing devices for fixing the dispensing member P to the reservoir R are conceivable. Instead of threads P21 and 114, other types of profiles that allow for securing, for example, by bayonet or snap-fit, are conceivable. In this case, there is always an axial fixing travel, during which perforation and / or engagement preferably occur.

[0048] The reference is a very magnified view. Figure 5a and 5b It can be seen how the piercing element 21 renders the sealing member 121 ineffective. It can be seen that the tube 20 terminates at a simultaneously beveled and thinned oblique section, thus forming the piercing element 21. The cross-section of the suction tube 12 is preferably constant for most of its length, and the suction tube 12 here includes an inlet section 125 with a reduced channel, thus forming a downwardly oriented shoulder 124. The sealing member 121 is in the form of a membrane connected to the shoulder 124. The membrane 121 includes a central portion 1211 of constant thickness and a thinned edge 1212 connected to the periphery of the shoulder 124. Therefore, as the tube 20 moves downward under the actuation of the inlet sleeve P1, the leading edge of the piercing element 21 will gradually break the thinned edge 1212 of the membrane 121, taking into account the oblique construction of the piercing element 21. Figure 5a As can be seen, the thinned edge 1212 has been partially cut. Figure 5b The tube 20 is visible in its final position, with its piercing element 21 inserted into the interior of the suction tube 12. The thinned edge 1212 has completely broken off, leaving only a small bridge of material to connect the membrane 121 to the shoulder 124. Therefore, the function of the shoulder 124 is easily understood; it allows the membrane 121 to be accommodated between the piercing element 21 and the suction tube 12. Thus, the membrane 121 does not detach from the rest of the mounting components, nor does it fall to the bottom of the suction tube 12. This avoids any risk of blockage or malfunction associated with the floating of the membrane 121.

[0049] Now refer to Figures 6 to 8 The second embodiment of the present invention will now be described. Figure 6 The mounting component 1' and insert 2' are visible, and they are made as a single unit, for example, by injection molding of a suitable plastic material. The mounting component 1' and insert 2' are connected by a tongue 253 and a hinge 254. Figure 6 As shown, both components are made using a flat mold. Mounting component 1' also includes a basket portion 11', a suction tube 12', and a retaining cup portion 14'. The basket portion 11' includes an upper annular region 114' forming a retracted edge 115. The basket portion also includes a one-way filter 13'. Insert 2' also includes a piercing element 21', a receiving slot 24', and an outer annular crown 25' forming a deformable flexible membrane 251'. A fixed annular flange 252 is located on the edge of the annular crown 25'. Therefore, it is readily understood that the insert 2' can be folded onto the mounting component 1' so that the piercing element 21' and the receiving slot 24' enter the basket portion 11'. In this way, the annular flat flange 252 will be accommodated within the retracted edge 115 so that the annular crown 25' is flush with the annular region 114' of the cup portion 14'. The fixed annular flange 252 can preferably be snapped into the retracted edge 115 in a non-sealing manner. This folding construction... Figure 7aAs shown in the diagram, the deformable membrane 251' is in its resting state, and the puncture element 21' is away from the sealing member 121, which may be similar to or the same as the sealing member of the first embodiment. A buffer space 10' is also formed between the basket portion 11' and the insert 2'. The fixing cup portion 14' has a threaded fixing sleeve 113' formed on the outside.

[0050] As mentioned earlier, the first step is to assemble the inlet sleeve P1 into the receiving slot 24'. This is in Figure 7b As shown in the image, insert 2' remains in its initial state, and the sealing components are intact.

[0051] Fixing the dispensing component P' to the reservoir R' has the function of moving the inlet sleeve P1, thereby causing the membrane 251' to deform and the puncture element 21' to move. The movement of the puncture element then clears the sealing component 121, as... Figure 8 As shown in the enlarged version.

[0052] Therefore, in this second embodiment, the insert 2' does not slide within the basket portion 11', but moves by the deformation of its membrane 251'.

[0053] Although manufactured as a single unit, it is also conceivable to manufacture the insert 2' separately and attach it to the basket portion 11'. In this case, the tongue 253 and the hinge 254 are eliminated.

[0054] As in the first embodiment, preferably, breaking the sealing member 121 and / or fitting the inlet sleeve P1 into the receiving slot 24' occurs during the axial fixation stroke of the dispensing member P' fixed to the reservoir R'.

[0055] In both embodiments, and in their contemplated variations, the inserts 2, 2' are integral components of the reservoir of the invention, as they are integrated into the reservoir long before the dispensing member is attached to it. The movement of the insert, actuated by the inlet sleeve, to break open, remove, or clear the draw tube is a fundamental feature of the invention. The insert is permanently fixed to the basket, even though its piercing element may move within the basket. The formation of buffer spaces 10, 10' is also advantageous, as it allows for the collection and capture of any fluid that may leak through the one-way valve 13, which can also be replaced by a one-way filter. The inserts also allow the dispensing member to be kept in a very satisfactory state of cleanliness, which is particularly advantageous because the reservoir of the invention is primarily used as a refiller, meaning that the dispensing member needs to be removed from the empty reservoir for later reinstallation on a full reservoir.
