Definitions

  • the present invention relates to a valve for discharging liquids from containers.
  • the present invention finds application in containers of "bag-in-box” type or of rigid type.
  • the present invention can also relate to rigid containers, usually used for water or similar liquids, or to other container types.
  • Valves for discharging liquids from bag-in-box or other container types are known characterised by a large number of parts, some constructionally costly, in particular to ensure air passage without container perforation.
  • Valves with air passage also exist consisting of numerous parts and with a cylindrical gasket, which are opened by rotation.
  • valves of known type present certain drawbacks.
  • valves are costly and difficult to produce as they are composed of a large number of parts.
  • an object of the present invention is to propose a valve for discharging liquids from a container which overcomes the drawbacks of the known art.
  • a particular object of the present invention is to propose a valve for discharging liquids from a container which is of simple and economical construction.
  • a further object of the present invention is to propose a valve for discharging liquids from a container which is easy and comfortable to use.
  • the reference numeral 10 indicates a valve for discharging liquids from a container 11 in accordance with the present invention.
  • the valve 10 discharges the liquid by the force of gravity.
  • the valve 10 can also operate when the container is subjected to positive pressure generated by forces other than gravity.
  • the valve 10 can evidently be constructed in different shapes, geometries and dimensions, and be used for different types of containers.
  • the discharge valve 10 comprises a valve body 1 presenting a fluid inlet opening 3 and a fluid outlet opening 4.
  • a fluid transit channel 12 is defined from the inlet opening 3 to the outlet opening 4 in the valve body 1.
  • This transit channel 12 is substantially of L-shape.
  • valve body 1 presents a first tubular portion 1 a and a second tubular portion 1 b which are connected together perpendicularly.
  • the valve body 1 also comprises a tube piece 2 coaxially fixed to the first tubular portion 1 a and required for coupling the valve 1 to the container 11.
  • the first tubular portion 1 a, the second tubular portion 1 b and the tube piece 2 present respective cross-sections which are substantially circular.
  • the cross-sections can be of oval, square or generally polygonal shape.
  • the diameter of the tube piece 2 is greater than the diameter of the first tubular portion 1 a.
  • the inlet opening 3 is defined on the tube piece 2, while the outlet opening 4 is defined on the second tubular portion 1 b.
  • the transit conduit 12 is defined at least by the tube piece 2, by the first tubular portion 1 a and by the second tubular portion 1 b.
  • the valve body 1 comprises fixing rings 9 such that the discharge valve 10 can be firmly fixed to the container 11 or to other liquid containers such that the inlet opening 2 of the body 1 of the valve 10 communicates with the fluid to be discharged.
  • the fixing rings 9 are disposed on the outside of the tube piece 2.
  • those particular fixing rings 9 shown in the figures consist of protuberances located close to the inlet opening 3. These rings are formed such as to ensure sealing capacity between the outside of the valve body and the inside of the container discharge neck when mounted by pressing.
  • O-rings or gaskets can be applied to the valve 10 or to a discharge neck of the container 11.
  • the valve 10 also comprises an adjustment element 15 operatively positioned along the transit conduit 12 to maintain it selectively open or closed.
  • the adjustment element 15 is positioned between the first tubular portion 1 a and the second tubular portion 1 b.
  • the adjustment element 15 can be switched between a closed configuration in which it closes the port of the transit conduit 12, so preventing fluid exit, and an open configuration in which it opens the port of the transit conduit 12, so enabling fluid exit.
  • the adjustment element 15 automatically switches from the open configuration to the closed configuration. In other words, once a user opens the adjustment element 15, this latter returns to the closed configuration without any action by the user.
  • the adjustment element 15 comprises a valving element 16 movable at least in part along a direction substantially coinciding with a longitudinal axis of the second tubular portion 1b.
  • the valving element 16 is a cylindrical piece which moves into and out of the second tubular portion 1 b to define respectively the closed configuration and open configuration of the adjustment element 15.
  • the diameter of the valving element 16 coincides with the inner diameter of the second tubular portion 1 b.
  • the adjustment element 15 also comprises a deformable portion 7 fixed to the valving element 16.
  • the deformable portion 7 is switchable between an undeformed configuration, assumed when the adjustment element 15 is in the closed configuration, and a deformed configuration, assumed when the adjustment element 15 is in the open configuration.
  • the adjustment element 15 when the adjustment element 15 is closed, the deformable portion 7 is undeformed.
  • the deformable portion 7 deforms because of the displacement of the valving element 16. Subsequently, the deformable portion 7 tends to return to its undeformed configuration by elastic return. In this manner, the adjustment element 15 automatically switches from the open configuration to the closed configuration, as stated above.
  • the deformable portion 7 when in the undeformed configuration, it presents a rigidity such as to maintain the valving element 16 stably within the second tubular portion 1b. In other words, when in the undeformed configuration the deformable portion 7 presents a rigidity sufficient to maintain the adjustment element 15 in the closed configuration.
  • the deformable portion 7 is disposed within a cylindrical jacket 13 formed in one piece with the first tubular portion 1 a and second tubular portion 1 b.
  • the deformable portion 7 is substantially of cup shape and is coaxially fixed to the valving element 16.
  • the deformable portion 7 is disposed such that its concavity faces in the opposite direction to the second tubular portion 1 b.
  • the deformable portion 7 presents a peripheral annular sidepiece 7a which is housed in an annular groove 17 provided on the inside of the cylindrical jacket 13. In this manner, the sidepiece 7a remains fixed while the remainder of the deformable portion 7 deforms when the valving element 16 is extracted from the second tubular portion 1 b.
  • An actuator 6 is connected to the adjustment element 15 for its movement.
  • the actuator 6 is connected to the valving element 16.
  • the actuator 6 is integral with the valving element 16. The actuator 6 is inserted into the cylindrical jacket 13.
  • the actuator 6 is substantially of cylindrical shape and is coupled to the cylindrical jacket 13 by a screw thread.
  • Figure 4 shows the thread 18 formed on the outer surface of the actuator 6.
  • the actuator 6 rotates within the cylindrical jacket 13, advancing or retracting.
  • the adjustment element 15 can assume a further stable open configuration. In other words, in this configuration the adjustment element 15 remains open without user intervention being required.
  • Stabilization means are therefore provided to enable this further configuration.
  • these stabilization means can comprise a projection provided on the actuator 6 to interfere with a corresponding groove provided on the inside of the cylindrical jacket 13, or vice versa.
  • the user rotates the actuator as far as an end position in which the projection engages the groove.
  • the protuberance has merely to be forcibly disengaged from the groove, for the adjustment element 15 to then automatically assume the closed configuration.
  • the deformable portion 7, the valving element 16 and the actuator 6 are formed in one piece to define the adjustment element 15. Consequently, these components can be produced simultaneously by an injection moulding process with positive economic advantages.
  • the adjustment element 15 can be formed of PP, PE, PA, POE or other thermoplastic material. This enables high flexibility in determining the valve closure force, as its geometry and thickness have merely to be slightly modified in order to achieve a greater or lesser closure force.
  • the deformable portion 7 is formed of the same material as the valve body 1 to enable the product to be more easily recycled.
  • a gripping member 14 is rigidly connected to the actuator 6 to enable a user to rotate the actuator 6.
  • the gripping member 14 is formed in one piece with the actuator 6.
  • the gripping member is connected to the actuator 6 by a screw thread.
  • the gripping member 14 is an ergonomic disc 19 of substantially circular shape.
  • the shape of the ergonomic disc 19 can be changed to adapt it to the requirements of different users.
  • a seal 20 is attached to the valve body 1 to close the outlet opening 4.
  • elastic means 21 positioned between the cylindrical jacket 13 and the actuator 6 are operative to urge the actuator 6 towards the second tubular portion 1 b. This aids and increases the action of the deformable portion 7 to enable automatic passage of the adjustment element 15 from the open configuration to the closed configuration.
  • the elastic means 21 comprise a spring 22 positioned between the actuator 6 and an abutment shoulder 23 provided on the cylindrical jacket 13.
  • the ergonomic disc 19 comprises a shaft 24 connecting to the actuator 6 and coupled thereto by a screw thread.
  • valve 1 does not comprise elastic means interposed between the abutment shoulder 23 and the actuator 6.
  • the ergonomic disc 19 comprises a shaft 24 connecting to the actuator 6 and coupled thereto by a screw thread.
  • valve according to the present invention is composed of a small number of parts. It is therefore easy and economical to construct. Moreover, it should be noted that once the valve is open, it returns to its closed configuration automatically without any other action being required.
