Definitions

  • the present invention refers to a device for discharging fluid from a container and a method for producing the device.
  • a device for discharging fluid from a con- tainer which comprises a flexible metering chamber which is connected to said container and communicates with the container and at the lower portion thereof terminates in a self-closing membrane valve provided to open at a pre-determined pressure upon the contained fluid.
  • the metering chamber has a seat for a float valve housed in the metering chamber, said float valve due to the buoy ⁇ ancy thereof normally being in contact with said seat, thereby keeping the contained fluid separated from the fluid in the- container.
  • a metered dis ⁇ charge takes place which as to the amount depends upon said compression.
  • the float valve has an elong ⁇ ated shape and also serves the purpose of limiting said compression.
  • a device of that character has proven to operate well when the contained fluid has a relatively high viscosity but not so well when thick creams or the like are to be expelled.
  • Another disadvantage is that the metering chamber needs to be vertically disposed to enable the float valve to operate properly.
  • the main object of the invention has been to provide a device for discharging fluid which in contradistinction to the known device may be successfully used for media with high viscosity as well as for media with low viscosity, which needs no particular orientation of the metering chamber and which may be produced at a low cost due to the fact that it comprises a few, easy-to-manufacture parts.
  • the invention has the character ⁇ istics of the patent claims.
  • Fig. 1 is a section through the new device, connected to a container
  • Fig. 2 is a partial section on a larger scale through an upper part of the device.
  • Fig. 3 shows ' in a view taken obliquely from below a tongue forming part of the device and adjacent parts of a wall cooperating with said tongue.
  • Fig. 4 finally, shows a detail of fig. 2 on a larger scale.
  • numeral 1 generally designates a container from which only a lower portion is shown.
  • the container may have any suitable shape and it may be in the form of a rigid container, a bag, a tube container or the like.
  • the container in the lower por ⁇ tion thereof has a connection piece 2, which preferably has a pair of circumferential grooves and the container further has a planar under sur ⁇ face.
  • the metering chamber which in the drawing has the general designation and which is manufactured from a material with elastically deformable characteristics has a metering chamber denoted as 5 and has a connection portion 6 which in the upper end surface thereof has annular profiled grooves 7 which are complementary to the connection piece 2 of the con ⁇ tainer with the grooves thereof.
  • the design is such that the metering device may be connected to the container 1 in that the connection piece of the former is snapped into the grooves 7 of the latter.
  • the sealing connection which is aimed at may be accomp ⁇ lished by means of so called plastics welding and to this end the connec ⁇ tion portion 6 has a planar annular flange 8 for cooperation with the planar portion 3 of the container.”
  • connection portion 6 is connected to a tubular portion 10, downwardly directed as seen in fig. 1.
  • a tubuilar portion 10 there is for a reason to be explained, provided a through, relatively narrow slot 11, which extends almost up to the upper end of the tubular portion 10.
  • an obliquely extending tongue 12 Integral with the portion 10 and extend ⁇ ing from the relatively thick wall portion 9 there is formed an obliquely extending tongue 12, which as will appear from the following acts as a return valve and closes respectively opens the communication between the interior of the tubular portion 10 and a recess 13, which consti- tutes the upper mouth of th'e metering device and which is in direct communication with the interior of the container.
  • connection portion 6 Further extending from the connection portion 6 in a downwards direction there is a thin-walled tubular portion 14 which in the lower free end thereof has a self-closing closure 15 capable of opening in response to a specific pressure in the metering chamber.
  • the metering chamber 5 with the connection portion 6 thereof, the inner portion thereof and the outer tubular por ⁇ tion ⁇ k thereof as well as the tongue 12 is made in one single piece and as appears from fig. 2 and fig. 4 the tongue 12 is thin-walled and has an elliptical shape.
  • the upper portion 17 of the tongue is in one piece with the wall 9 which according to the illustrated embodiment constitutes the upper part of the inner portion 10.
  • a slit 16 see fig. 3 which follows the contour of the tongue.
  • the injection mould may have cores directed towards each other and con ⁇ tacting each other in a narrow edge zone and this edge zone in fact con ⁇ stitutes the narrow slit.
  • the wall portion 9 and the inner portion 10 has a wall-thickness which is considerably greater than the wall thickness of the tongue 12 there w ⁇ 11 be a different shrinkage in the tongue and the immediate vicinity thereof when the plastic material solidifies and by arranging these cum ⁇ ulations of material in a suitable manner it has been possible to obtain the effect that the slit 16 which is inevitable will be eliminated there ⁇ in that the tongue in spite of this original slit will after the manu- facturing seal against the inner wall of the inner portion and it is thus seen that in this manner there has been provided a simple and in ⁇ expensive return valve.
  • the plastics material consists of polypropene it has been found that the desired effect will be attained when the wall portion 9 will have a thickness which should be 4-5 timed the thickness of the tongue 12 but which may be within the interval! of 3-6 times.
  • the wal l thickness of the tongue should be 0,2-0,6 mm and preferably 0,4-0,5 mm.
  • the container is first filled with the fluid, for instance hand cream, which is to be discharged.
  • the fluid for instance hand cream
  • the slot 11 is provided.
  • the co pressable thin-walled tubular part 14 When it is desired to effect a discharge the co pressable thin-walled tubular part 14 is grabbed by the hand and is compressed more or less. If- for instance- a maximum discharge is desired the tubular part 14 is compressed to such an extent that it will come into contact with the inner portion 10.
  • the membrane valve 15 preferably comprises plastics components made in an injection moulding process and which may be snapped into each other res ⁇ pectively in the mouth of the tubular portion 14.
  • plastics components made in an injection moulding process and which may be snapped into each other res ⁇ pectively in the mouth of the tubular portion 14.
  • it may comprise a first component which has a relatively thick-walled annular part 18, which by means of radial ribs 19 is connected to a cen- tral, axially extending stud 20 and a second component which preferably surrounds the annular part 18 and continues in a membrane 21 provided with a central outlet opening 22, which due to the pre-tension of the membrane is normally closed by means of the end portion of the stud 20.
  • the membrane of course should be resilient and polypropene plastic has proven to be a suitable material for making the two components of the mem ⁇ brane valve.

Abstract

Un dispositif permettant de décharger un fluide contenu dans un récipient (1) comporte un système volumétrique se présentant sous la forme d'une partie extérieure (14) tubulaire, compressible et à mince paroi et d'une partie intérieure (10) tubulaire relativement rigide qui communique avec l'intérieur du récipient (1) et dans laquelle est prévue une soupape de décharge (12) qui permet au fluide de passer du récipient dans la partie intérieure mais pas dans le sens inverse. La partie extérieure tubulaire (14) se termine par une soupape de décharge (15) qui s'ouvre en réponse à une pression prédéterminée sur le fluide contenu dans le système volumétrique. La partie tubulaire intérieure possède également une fente (11) qui s'étend depuis son extrémité libre jusqu'au voisinage de son extrémité opposée, et au-dessus de l'extrémité de la fente se trouve dans la chambre volumétrique un espace dans lequel l'air évacué en liaison avec le remplissage du système volumétrique peut être cumulé et comprimé pour exercer un effet de tampon. Est également décrit un procédé de fabrication du dispositif selon lequel au moins la partie intérieure (10) et la languette (12) sont faites d'une seule pièce et présentent des configurations et des épaisseurs de paroi telles qu'une étanchéité suffisante est obtenue entre la partie intérieure et la languette grâce au retrait du matériau.
