The present invention will be described with reference to the above-mentioned drawings. Liquid products with medium to high viscosities that should be kept out of the air, such as gel or cream type cosmetics, are stored in storage containers 2 of varying capacity depending on the amount of product being stored. U. S. Patent No. 5,152, 434 describes, for example, any reservoir in a pump having a first piston that restricts the pumping chamber supplied by a reservoir that is disposed in a cylinder and is restricted by a second flow piston. Without limitation, the flow piston 23 is disposed opposite the liquid inlet 22 and in the groove in the cylinder 24, with the cylinder 24 and the piston 23 delimiting the storage vessel 2. . The storage container 2 is provided to the pumping chamber 1 through a supply port provided with a return prevention valve 21. The anti-return valve 21 prevents the liquid product from circulating from the pumping chamber 1 toward the storage container 2, as shown in FIG. 1, and from the storage container 2 toward the pumping chamber 1. Allows circulation of the liquid (F1). Non-limitingly, the anti-return valve 21 includes a bead or needle that touches the conical edge of the liquid supply port 22, or a membrane blocking the liquid supply port 22, or other supply closing element. The retaining elements of the closing element are arranged, for example, opposite the feed port 22 in the pumping chamber 1.

As shown in FIG. 2, the liquid is sucked into the pumping chamber 2 through the supply port 22, and then the liquid is discharged from the pumping chamber 2 through the distribution port 31 provided in the distribution plate 3. (F3). One or more partitions 11, 12, 14, 37 surrounding the pumping chamber form a hermetic junction between the supply port 22 and the distribution port 31. In this way, the user can use a certain amount G of products placed on the distribution surface S3 of the plate 3. Without limitation, the upper surface S3 of the distribution plate 3 is concave or straight, and the distributor, for example, is disposed upwards with its distribution surface S3.

When suctioning F1 the liquid contained in the storage container 2 into the pumping chamber 1, the volume of the storage container 2 is reduced correspondingly to the volume of the liquid in which the capacity is contained. For example, as the liquid is sucked into the pumping chamber 1, the piston 23 advances toward the supply port 22 (F2). As shown in FIG. 1, the liquid suction F1 into the pumping chamber 1 through the supply port 22 is made when the pumping chamber 1 is expanded. The pumping chamber 1 is formed of a partially deformable partition 11, the expansion of the pumping chamber being due to, for example, an enlarged movement M1 of the deformable partition 11. Non-limiting, the maximum volume of the pumping chamber corresponds to the position of the deformable partition 11 in a resting state or partially compressed state. Upon inflation of the pumping chamber, the liquid from the storage vessel 2 pushes the anti-return valve 21 and causes the ascending movement F2 of the piston 231 in the cylinder 24. Since the storage container does not contain air and the pumping chamber 1 is all filled with the liquid product, the liquid product to be distributed comes into contact with the air only when it comes out through the distribution port 31. Non-limitingly, the reservoir is emptied until the piston 23 is pressed against the feed port 22. Non-limitingly, the piston 23 delimiting the storage container comprises a connecting means such as a grooved hole 231 on the outwardly facing side, for example, a valley through which the bone can be hung. Pull 23 out of the cylinder 24 to refill the reservoir 2.

The deformable partition 11 whose inner wall forms part of the pumping chamber 1 is arranged in the distributor storage space 30. The deformable bulkhead is for example secured to the rigid bulkheads of the pump or forms part of a part, for example a bell shaped cover with deformable elasticity contained within the pump. Without limitation, for example, the accommodating space 30 in the form of a cylinder extends above the lower partition wall on which the supply port 22 is formed. The lower partition wall, which is shared with the storage vessel cylinder without limitation, forms, for example, the lower wall 37 of the pumping chamber 1. The lower partition wall extends from the side wall 35, for example around it. Without limitation, it has an angular cross section that is circular or round or polygonal, for example square, hexagonal, or octagonal. The upper part of the storage space 30 is closed by the distribution board 3, for example. Non-limiting, the distribution plate is moved so that the user can press or push button 38 is formed in the distribution plate (3). When the plate or button connected to the deformable bulkhead is pressed, the deformable bulkhead is deformed and compressed (M2) to reduce the volume of the pumping chamber and discharge the liquid product through the distribution port.

The deformable partition wall consists of, for example, a deformable and elastic convex portion 11, which forms a bell shaped cover 11, 12, 13, 14 in which a pumping chamber 1 is formed. . The bell-shaped lid is fixed by the connecting means in the storage space 30. The bell-shaped cover comprises, for example, a rigid ring 13 that presses the side walls 36, 351 of the storage space 3. The side wall pressing the bell-shaped cover fixing ring 13 is, for example, a side wall 351 delimiting the storage space 30, or as shown in FIG. 3, the lower wall 37 of the storage space 30. It is a wall 36 formed by a cylindrical ring extending. This pressing ring whose inner diameter corresponds to the outer diameter of the pressing ring 13 is arranged, for example, around the feed port 22. Non-limitingly, the rigid retaining ring, for example, extends from a convex portion that is elastic on one side and presses the lower face 37 on the other side, for example a closed lip around the feed opening 22. Extends from 14. The convex portion 11 extends into a tube 11 or conduit which connects to the distribution plate 3, which, but is not limited to, opposite the distribution port 31.

The tube, for example with a circular transverse cross section, is inserted into the groove 39 of the distribution plate 3, which is fitted around the rigid tube 12 and holds the tube 11 together with the distribution plate 3.

According to another example as shown in FIG. 10, a deformable bellows or corrugated conduit is secured to the distribution plate, for example by gluing.

According to another embodiment, the bell-shaped cover comprises a lower ring 15 which is fixed around the lower or side wall 37 and the supply port 22 of the receiving space 30, for example by gluing. In contrast to the bottom wall 37, the glued ring 15 extends into the deformable and elastic convex portion 11 and into a tube or tube in the form of a bellows as described above.

An elastic and deformable sealing element 32 closes or opens the outlet 31 which is located in the distribution plate 3 or in connection with the parts constituting the deformable pumping chamber. For example, the sealing element disposed on the discharge plate has a constant maximum thickness H32 and a constant upper pressing surface in the transverse cross section of the distribution opening 31. Without limitation, the pressing face of the sealing element may be circular, elliptical, rounded, or angled to form a polygon such as, for example, a square, hexagon, or octagon. Sealing elements disposed on the distribution plate, such as, for example, a disc made of a flexible or deformable plastic material, may be provided with a fixing point 321 with at least one of the plates 3 and openings of the opening 31 to exit the liquid product. At least one flow portion 322. For example, the resilient sealing element 32 disposed on the distribution plate 3 is located in the recess 320 having a constant depth H3 not less than the thickness H32 of the sealing element, but in a closed state. To prevent the sealing element from falling over the upper surface (S3) of the distribution plate (3). The recess also has a cross section covering the surface of the sealing element.

According to another example, the sealing element is connected to a tube extending the deformable wall, the sealing element entering inward relative to the upper face of the distribution plate.

Due to its elastic nature, the sealing element clinging to the edge of the opening returns to the closed position of the distribution port 31 after the liquid product has passed. The sealing element is fixed, for example by gluing or tightening. The distribution plate 3 or the sealing element 32 each comprises a projection 324 to be inserted into a tightening hole formed in each of the sealing element 32 or the distribution plate 3, for example.

The user passing the finger along the distribution surface S3 passes through the sealing element 32 without being caught by the sealing element 32, for example, because there is no risk of opening the distribution opening in an accident, for example, The product can be stored away from the air. The sealing element 32 arranged in the recess 320 thus has an appearance that is continuous with the upper surface S3 of the distribution plate 3. Plating of the sealing element in the closed state is ensured by its elastic nature and by suction in the pumping chamber 1.

FIG. 5, for example, includes a first region 321a which is fixed to the distribution plate 3 by gluing and a second region 322b which presses the pressing surface of the distribution plate 3, for example. ). The first and second regions surround the flow third region 322a of the disc 32a, which is disposed opposite the distribution port 31.

FIG. 6A shows an example of a cleaved disc 32b comprising a peripheral area 321b which is fixed to the distribution plate 3, for example by gluing. Non-limitingly, the gaps 3200 separate the split disc 32b that includes flow centers that block the outlet and press the crossbars disposed transversely to the outlet of the distribution plate 3 as shown in FIG. 6B. Release. Each of the flow portions of the split disc 32b includes an area 322d that comes in contact with one or more arms 325 and a closed area 322c of the passage for the liquid product. By way of non-limiting example, the disc has two passes through the center of the cleaved disc 32b, for example, dividing the flow portion of the disc into one of four arms with one arm or multiple arms 325 with four arms. Contains breaks. The number of support arms 325 is equal to, for example, the number of divided flows of the split disc 32b. The support arm 325 is disposed in the same plane as the engaging surface 326 with the disc 32b of the distribution plate 3 together with the upper pressing surface.

According to one variant of the embodiment, as shown in FIG. 4, the flow portion of the sealing element that presses the distribution plate 3 rests against the stop 323 protruding from the distribution plate 3. Sealing elements, such as, for example, flexible and deformable discs, are slightly deformed when they come into contact with the stops to improve sealing in the closed state of the outlet 31. The pressure of the sealing 32 element acting on the distribution plate is due in particular to its elasticity and the suction phenomenon in the pumping chamber 1.

According to one variant of the embodiment, as shown in FIG. 11, the sealing element, which leads in part to the deformable part forming the pumping chamber 1, comprises an upper face which is split and convexly curved outwards. The gaps, for example, form parts that are tightened together without opening outwardly or leaking at rest.

In order to distribute a certain amount of liquid product, for example gel or cream, to the upper surface S3 of the distribution plate 3, the user presses the distribution device via pressure means to compress the deformable partition wall (M2). The volume of the pumping chamber 1 is reduced. The liquid product then pushes out the sealing element 32 as shown in FIG. 2. The user presses, for example, push button 38 installed on the flow distribution plate 3 surface S3 or on the floating or fixed distribution plate. Then, the distribution device is reduced to the original position by elasticity, and the deformable partition wall is found again by the expansion of the deformable partition wall. Expansion of the pumping chamber 1 then causes suction in the pumping chamber and causes the sealing element 32 to cling to the edge of the tightly closed outlet 31. The suction phenomenon and the elastic properties of the sealing element tend to reduce the sealing element to the closed state of the distribution opening during suction F1 in the pumping chamber 1, as shown in FIG.

Non-limiting, as shown in FIG. 2, the deformable partition is compressed by the pressure of the user applied to the upper surface S3 of the presented distribution plate 3. The compressive force M2 exerted by the user is transmitted directly to the rigid tube 12 leading to the deformable partition or the deformable partition via, for example, the distribution plate 3, the rigid tube 12 being deformable to be compressed. A compressive force is applied to the elastic partition wall 11, so that the pumping chamber 1 is reduced. When the user no longer applies pressure, the deformable portion is enlarged and deformed by elasticity and pushes the distribution plate or tube.

According to one variation of the embodiment, as shown in FIG. 10, the deformable partition includes a bellows-shaped opening that extends into a tube 120 that is harder than the rigidity of the deformable, deformable partition 11. The bellows-shaped pipe 120 is inserted into a groove 39 under the distribution plate, for example, and communicates with the distribution port 31 in the distribution plate 3. The tube 120 in the form of a bellows with rigidity above the deformable partition 11 transfers the first pressure to, for example, the deformable partition, and then an increase in the application of pressure and a second compressive force is for example in the form of a bellows. Resulting in deformation of the tube 120. Advantageously, under constant pressure the deformation of the bellows-shaped tube 120 is minimal, releasing a constant first portion of the viscous liquid, such as, for example, a gel. Thus, the application of a stronger pressure enables the deformation of the bellows-shaped pipe 120 immediately after the deformation of the deformable partition 11. Thus, the deformation becomes more pronounced and a more significant reduction of the pumping chamber is made, thereby increasing the amount of liquid product distributed.

According to one variant of the embodiment, as shown in FIG. 11, the deformable partition 11 is connected to the sealing element with a flexible tube 121 fixed to the passageway of the distribution plate, for example by gluing or tightening. And extending openings. Advantageously, applying pressure to the distribution plate will cause deformation of the part comprising the flexible tube 121 and in particular deformation of the upper edge of the tube. The deformation of the upper edge of the flexible tube 121 thus leads to the opening of the sealing element 32. Without limitation, the lower face of the distribution plate comes in contact with the deformable partition 11. Without limitation, a single part forms a leak-tight room between the supply port 22 and the distribution port 31.

According to one variant of the embodiment, as shown in FIG. 3, the distribution plate 3 is flexible to press one wall of the deformable partition 11 or the receiving space 30, for example convexly curved, through its inner surface. And elastic legs 301. The pressure exerted by the user is transmitted, in part, through flexible and resilient legs 301, for example, applying compressive force to the resilient convex portion 11 of the deformable partition 11. Upon inhalation, the flexible legs exert a return force to the initial position on the distribution plate and the flexible legs press on a wall of the storage space 30 in which the deformable partition 11 is arranged, for example.

According to one embodiment, as shown in FIG. 9, the distributing plate 3 is deformable, such as, for example, a flexible and elastic convex portion of a bell-shaped cover on the lower face facing the deformable partition 11. It includes rigid brace legs 302 against the partition 11. Non-limitingly, the rigid brace legs are arranged against the deformable convex bulkheads and follow the form of the bulkheads in a stationary state or lean against partially deformable bulkheads that are partially compressed in the stationary state of the distribution device. It is supported against an upper pedestal element, such as an upper ring 4, which presses against the circumference of the distribution plate 3.

According to one embodiment, without limitation, compression of the pumping chamber is effected by the user pressing the translational flow push button 38 against the distribution plate 3. Without limitation, the translational flow push button is connected to a fixed or fluid distribution plate 3. The push button 38 includes, for example, a rigid leg 303 that rests against a deformable partition such as a convex portion of a bell shaped cover. The button 38 is guided by a partition 381 which contacts the support surface 351 formed by the partition wall 35 of the distribution device, for example, or the button 38 is supported by the support surface 361 of the distribution plate 3. Guided to the side.

Non-limitingly, the flow distribution plate 3 containing the button 38 also allows for applying a compressive force and includes an overlap portion 362 having an obliquely cut portion of the push button 38 without limiting the distribution plate. When pressed, the button 38 is interlocked. When the user presses only the button 38, the distribution plate 3 is not moved. When the push button 38 is pressed, a certain amount is distributed, for example, less than the amount distributed by pressing the distribution plate 3.

Without limitation, a bellows-shaped tube 12 or tube above the deformable partition formed convexly connects the distribution plate 3 and the deformable partition such as, for example, the compressed convex portion 11 of the bell-shaped cover. 8, the tube or tube is centered against the deformable convex bulkhead or biased to one side as shown in FIG.

According to a variant of the embodiment, not shown, a central tube connected to the deformable partition leads to a passage formed in the center of the distribution plate 3, the passage of the distribution plate 3 transversely transversely across the distribution plate 3. It leads to the distribution plate 3 upper surface S3 in the peripheral region of the plate 3.

Non-limitingly, the distribution plate 3 is guided in parallel to the side bulkhead 35 which forms a receiving space 30 in which a deformable bulkhead which is flexible and partially delimits the pumping chamber is arranged. According to one embodiment, as shown in FIG. 9, the induction is performed by the side wall of the distribution plate 3, which includes the side pressing the induction surface 351 of the distributor bulkhead. For example, the pressing surface of the distribution plate 3 which contacts one wall of the storage space 3 enables the distribution plate 3 support to carry out parallel orientation and maintain its orientation, the distribution plate being for example It is horizontal.

According to another embodiment, the distribution plate comprises rounded side edges which enable movement and tilting through the pivoting of the distribution plate 3. Without limitation, the upper surface S3 of the distribution plate 3 presses on the ring 4 forming the upper pedestal. The loop 4 is fixed, for example, by means of a screw fastener and presses the circumferential part of the upper surface S3, limiting the movement of the distribution plate 3 upward. Non-limitingly, flexible legs 301 that push against the deformable bulkhead or wall of the receiving space 30 enable distribution plate induction and add to the revolving force towards the uncompressed position of the deformable bulkhead. Force is applied to return the distribution plate to its original position, eg in a horizontal position. Advantageously, the tiltable distribution plate in contact with the upper limiting ring 4 allows the user to press a side around the distribution plate to execute the lever, and the distribution plate is pressed against the stop ring 4 and pivoted. .

Advantageously, convex deformable partitions can be compressed by pressing a number of points, such as for example the deformable convex portion 11 of the bell shaped cover. In addition, the distribution plate, which can be freely rotated, can also be pressed slightly, allowing the user to better control the pressing force than in the case of a pumping chamber formed with a piston in the cylinder. Furthermore, in contrast to the present invention in which a flow element, for example a distribution plate, does not require an intact connection with the cylinder, according to the prior art, the piston must be intactly connected with the cylinder. On the contrary, according to the arrangement according to the invention it is possible to press with various forces in a variety of ways, the distribution plate being kept flat or allowing one or several rotations, for example tilting.

It will be apparent to those skilled in the art that the present invention enables various other forms of embodiments without departing from the scope of the invention as claimed. Accordingly, the present embodiments should be considered as illustrative, but may be modified within the scope defined by the appended claims, and the invention should not be limited by the details set forth above.
