Description

  • The present invention concerns a dosing valve which allows the content of a flexible container to be filled as well as dispensed via the valve. In particular, it concerns a dosing valve which is operated under pressure of the content in the product recipient or by moving a shaft in which the product is moved.
  • The dispensing of products from flexible product recipients using a pressure means is known. A pressure means, such as a mechanical or hydraulic device, ensures that the product is moved from the product recipient. In most cases the product needs to be dosed from the product recipient with the necessary precision. To do so, dosing valves are used. In addition, product recipients are filled with a product. When filling product recipients, such as plastic bags, the sterility of the content may be jeopardised. In most cases, a separate filling mechanism is used, increasing the risk of contamination.
    Dosing valves are well known from the prior art. Such a dosing valve has already been described in BE10177646 , which describes a dosing valve to dispense the content of a container by means of a self-regulating dosing chamber. The present invention is aimed at improving such a dosing valve, by using the valve to fill as well as dispense a product.
  • The invention concerns a dosing valve according to claim 1 with a housing containing a dosing chamber with a movable cylinder, which moves along a hollow shaft. The product moved through the hollow shaft into a dosing chamber in order to be dispensed via a nozzle or into a guide channel to fill a product recipient with a product. The main characteristic of the hollow shaft is that it features a number of bores, which allow the product to be dispensed or filled selectively. In addition, the hollow shaft is also characterised by the fact that it is moved by means of pressure differences in the valve or in the product recipient.
  • The first advantage of the present invention is that it allows the same dosing valve to dispense the product from the product recipient, but also to fill the product recipient with the product.
  • A second advantage is that the dosing valve has a limited number of components, allowing a quick and easy assembly of the valve.
  • Using pressure differences, created in the product recipient and the dosing valve, the operation of the dosing valve is simplified.
  • The invention is detailed in the enclosed figure.
    • Figure 1 : cross-section of the dosing valve
    • Figure 2 : cross-section of the movable shaft with built-in spring
  • According to figure 1 the dosing valve (1) consists of a housing (2) which contains a dosing chamber (3) and a guide channel (4). The housing (2) contains a first cylinder (2a) with a larger diameter than that of a second
    cylinder (2b). This cylinder (2b) is connected to the product recipient, which is not shown in the figure. The product recipient can be a flexible container, such as a bag. The product is moved from the product recipient using a pressure means. Cylinder (2a) of the housing (2) forms the dosing chamber (3). In other words, the dosing chamber (3) consists of cylinder (2a) and the extremity (6) of the housing (2a), on the side of the nozzle (8). The dosing chamber (3) contains a piston (7). This piston (7) ensures that the product in the product recipient is moved from the dosing chamber (3) to the nozzle (8), as well as from the nozzle (8) to the product recipient. The volume of the dosing chamber (3) can be adjusted depending on the required dosing volumes.
    In a possiole embodiment, piston (7) is made from an elastic material, allowing a tight fit with the cylinder wall (2a) and the hollow shaft (10). In another embodiment, as shown in figure 1 , piston(7) is equipped with seals (7a,7b) in order to seal the cylinder wall(2a) and the movable shaft (10), respectively.
    At least one channel (9) is created concentrically around the guide channel (4) between the housing (2b) and the guide channel (4). This channel (9) allows the product to be moved from the product recipient into the dosing chamber (3). In a first position, the piston (7) rests on the edge of the housing (2a) and the extremity of the guide channel (4), near the channel (9). In a second position, the piston (7) rests against the extremity (6) of the dosing chamber (3). According to figure 1 , a spring (25) is fitted in the dosing chamber (3) to push the piston (7) against the edge of the housing (2a) and the extremity of the guide channel (4) if the dosing chamber (3) is full.
  • A shaft (10) extends centrally through the dosing chamber (3) and the guide channel (4). The shaft (10) is fitted with a number of bores (11,12,13). According to figure 1 , bores (11,12) are located at the nozzle (8), while bore (13) is located at the guide channel (4).
    The shaft (10) can be moved longitudinally through the valve. This means that the bores (11,12,13) can be moved by moving the shaft (10). The shaft (10) can be made from a single part or several parts. According to this embodiment, the shaft (10) consists of 2 parts, connected to each other. The place where both hollow shafts (10a,10b) are connected to each other is not hollow. The two parts (10a,10b) are preferably connected by means of a quick coupling, such as a snap-fit connection, bayonet connection, screw coupling, etc. Furthermore, in a possible embodiment, the parts can also be connected by means of gluing or welding.
    A first part (10a) of the shaft (10) is located at the extremity (6) of the housing (2) and forms the nozzle (8). This first part (10a) of the shaft (10) is hollow and features a bore (11). The second part (10b) is also hollow and connected to the part (10a), extending through the dosing chamber (3) and the guide channel (4). Bores (12,13) are located in the second part (10b). A first extremity opening (14) of the hollow shaft (10b) leads to the guide channel (4), which also features an opening (15). The opening (15) of the guide channel (4) is connected to the product in the product recipient. The opening of the extremity (14) is closed off with a body (16). According to this embodiment, the body (16) features a convex part closing off the opening of the extremity (14).
    According to figure 1 , the body (16) is connected to a spring-mounted body (17). This can be a spiral spring made from stainless steel or plastic. Both the body (16) and the spring-mounted body (17) can have another form. According to another possible embodiment, which is not shown in this figure, the opening (14) of the hollow shaft (10b) is closed off by means of an elastic body. This elastic body can be made from a plastic or an elastomer, with or without reinforcement. This elastic body replaces the spiral spring (17) and the closing body (16). According to figure 2 , in another possible embodiment, a spring-mounted body (26) with a stop valve (27) is fitted in the hollow shaft (10b). In this embodiment, the hollow part of the shaft (10b) is wider to accommodate the spring-mounted body (26) with the stop valve(27). Furthermore, a retainer (29) is fitted near the opening (30). The opening (30) is closed off with a stop valve (27). The spring (26) with stop valve (27) is mounted in opening (14), using well-known technologies, such as a ring (28).
    The other extremity (18) of the hollow shaft (10b) is connected to the extremity (19) of the hollow shaft (10a), thus connecting the shafts (10a,10b). Where both hollow shafts (10a,10b) connect, i.e. at both extremities (18,19), the shaft (10) is not hollow. Both extremities (18,19) have a solid connection between the hollow shafts (10a,10b). The hollow shaft (10a) forms the nozzle (8) of the valve (1). The second extremity of the hollow shaft (10a) has an opening (20), allowing the product to be filled or dispensed from the product recipient.
    The shaft (10), comprising a first part (10a) and a second part (10b), can move in relation to the dosing chamber (3) and the guide channel (4) by means of pressure, thus placing the bores (11,12,13) in the desired position, depending on whether the product needs to be filled or dispensed through the valve. A first bore (11) is located in the shaft (10a) and surrounded by a sealing ring (21). This sealing ring (21) surrounds the housing (2) and the extremity (6). The sealing ring (21) is supported by a ring (23), located in a groove in the wall of the housing (2a) and surrounding the shaft (10). The sealing ring (21) and the shaft (10) are surrounded by the closing part (24) over the extremity (6). The closing part (24) keeps the housing (2), the movable shaft (10) and the sealing ring (21) together. The closing part (24) is fastened to the housing (2) by means of well-known technologies or closures, such as welding, crimping, gluing, screwing or interlocking.
    On the one hand, bore (11) serves to move the product through the hollow shaft (10a) to the nozzle (8); on the other hand, it also serves to move product from the nozzle (8) into the dosing chamber (3). This bore (11) is released when the hollow shaft (10) is pushed. The second bore (12) is located in the dosing chamber (3) in the shaft(10b) and bore (13) is located at the extremity (14). Recesses with sealing rings (22a, 22b) are fitted on both sides of the bore (13). Bore (12) ensures both the filling and emptying of the dosing chamber (3). Bore (13) only serves to move the product through the hollow shaft (10b) from the channel (9) into the dosing chamber (3), causing the piston (7) to move first in the direction of the extremity (6) and then back to the edge of the housing (2a) and guide channel (4). As a result, the dosing chamber (3) is filled, which allows the product to be dispensed.
    The operation of the valve (1) is detailed below.
    To dispense the product from the product recipient, pressure is exerted on the product recipient, causing the product to move the piston (7) through the channel (9) in direction A, according to figure 1 . If the shaft (10) is not pushed, the bore (11) is closed off by the seal (21), bore (12) is located in the dosing chamber (3) and bore (13) and seal (22a) of the hollow shaft (10b) are located in the dosing chamber (3). Seal (22b) closes off the guide channel (4). The product fills the dosing chamber (3) through bore (13) and via bore (12). The product in the dosing chamber (3) and the pressure exerted by spring (25) push the piston (7) against the edges of cylinder (2b) and guide channel (4).
    To dispense the product, the shaft (10) is pushed in the direction of the guide channel (4) and the bore (13) and seal (22a) in the guide channel (4) are closed off. Bore (11) is released, allowing the product to flow from the dosing chamber (3) through the hollow shaft (10a) into the opening (20) of the nozzle (8). The pressure exerted by the product flowing in via the channel (9) pushes the piston (7) in the direction of extremity (6) into the dosing chamber (3) and dispenses the product through the nozzle (8).
  • The product recipient is filled with a product via the shaft (10) as well, in direction B, according to figure 1 . Under pressure and when pushing the hollow shaft (10a) through opening (20) of the nozzle (8), the product enters the dosing chamber (3). Bore (11) is released when shaft (10) is pushed, causing the product to enter the dosing chamber (3). The filling of dosing chamber (3) pushes the piston (7) against the edge of cylinder (2b) and the guide channel (4). The product moves from the dosing chamber (3) through bore (12) into the hollow shaft (10b) in the direction of opening (15). Bore (13) is located in the guide channel (4) and is closed off by seals (22a,22b), causing the product to exert pressure on the body (16). The pressure exerted by the product pushes the spring-mounted body (17), releasing the product via opening (14) and thus filling the product recipient through opening (15). After filling, the spring-mounted body (17) is released and opening (14) of the hollow shaft(10b) is closed off again by the body (16). The spring-mounted body (17) pushes the shaft (10) back in the direction of the extremity (6).
    As indicated above and according to figure 2 , in a possible embodiment, an additional spring-mounted element (26) with a stop valve (27) can be fitted in the hollow shaft (10b). According to this embodiment, the flow in the hollow shaft (10b) is regulated by opening (30) into opening (15). The pressure exerted by the product while filling pushes the stop valve (27) of opening (30) against the retained (29), allowing the product to flow via opening (14) to opening (15).
    This embodiment with a spring-mounted body (26) and stop valve (27) in the hollow shaft (10b) can be combined with the spring-mounted body (17) with stop valve (16) in the guide channel (4).
