Definitions

  • the present invention relates to a liquid distribution valve to be placed on a container having a single flow orifice, in particular being a bottle arranged with the neck turned down.
  • Document EP427.495 has already proposed a distribution valve liquid, capable of being adapted to a container having a single orifice, including a bottle.
  • the valve in question includes two flexible tubes juxtaposed, a means of closing by crushing the two tubes and a means obturator capable of hermetically sealing the orifice around the two tubes when placing the valve on the container.
  • One of the two tubes is used for the passage of the liquid while the other tube is used exclusively for the passage of the air. It is important that the volume of liquid leaving the container is replaced by air and be it regularly if you want to avoid the jerk effect that we observe when we empty a bottle by turning it over, an effect that causes a deformation of the bottle, depending on the pressure variations, when it is made of flexible plastic.
  • the valve of the invention overcomes these drawbacks.
  • one of the two tubes presents locally towards its end facing the inside of the container a reduced internal diameter whereby there is no need for one of the tubes to rise inside the container above the level of the liquid to form a pick-up tube 'air.
  • the user has more to handle the container to pour the liquid but it is enough to put in place the aforementioned tap on the opening of the container, the two tubes being crushed thanks to the closing means, to return the container, the opening then being down, position it on a suitable support and then take as much whenever necessary the quantity of liquid desired thanks to the closing means.
  • This is possible with containers, of the type with large capacity bottles in plastic material.
  • the presence of the second tube of reduced diameter makes it possible to adjust the gas flow entering the container through this second tube, when the pressure liquid near the opening is equal to or less than the pressure atmospheric; thus it is possible to obtain a regular flow of the liquid, while avoiding the jerky effect.
  • This flow is preferably done by the first tube, but also partly through the second tube with the shrinking according to pressure conditions. There is therefore no longer any need of an air intake as in document EP427,495.
  • the second tube can be short inside the container. The applicant was able to determine that by judiciously choosing the internal section of the two tubes and in particular from the strangled part of the second tube it was possible to obtain a good flow liquid from the beginning to the end of the container.
  • the cross-sectional shape of the two tubes should be designed to have the largest possible liquid passage in position open while having the smallest possible deformation to pass from the open position to the closed position, when the two tubes are crushed by the closing means.
  • An oblong, oval, elliptical or shaped section flattened circle allows these two parameters to be combined.
  • the two tubes have the same section, except well on the area of the second tube where the section is narrowed, in order to facilitate the pinching of the two tubes and having a good seal in the closed position.
  • the total height between the ends on the one hand of the outer portion to the container of the first tube and on the other hand of the portion inside the container of the second tube is of the order of 50 to 60 mm.
  • the narrowed part of the second tube is towards the end of this facing the interior of the container has two advantages; all firstly, this prevents said second tube from filling with liquid in the off position, since the narrowed section is determined so as not to allow passage liquid under normal pressure conditions inside the container; of the more it allows the second tube to be emptied easily in case, in operation, the liquid would pass through the narrowed section during a pressure variation.
  • This localization of the narrowed portion of the second tube therefore makes it possible to trap the air situated between the zone of said second tube crushed by the closing means and the narrowed portion.
  • the first tube has a portion, external to the container, which has a length greater than the outer portion of the container of the second tube.
  • the liquid dispensing may be interrupted when the liquid level in the glass or other container to be filled reaches the ends of the two tubes and the two so-called tubes are themselves filled with liquid.
  • the fact that the second tube is shorter than the first allows, in this case, to automatically reboot liquid distribution thanks to the difference in lift height in the two tubes.
  • the second tube has a portion intended to be at inside the container, when the tap is in place around the opening, which has a length greater than that of the corresponding portion of the first tube.
  • the portions, located inside the container, of the two tubes have the same length, there may be a risk that gas bubbles entering the container by the second tube are entrained by the liquid distributed in the first tube, which would disturb the flow of said liquid. Shifting in height the second tube disperses the gas bubbles in an area of the container distant from the immediate vicinity of the end of the first tube by which flows the liquid.
  • this offset in height of the second tube to the interior of the container makes it possible to limit the size of the portion of the first tube outside the container.
  • the lengths of the portions of the first and second tubes, outside the container are sufficient to be accessible by means of closing by crushing.
  • the end of the inner portion of the second tube is fitted with a non-return valve.
  • a non-return valve This particular provision covers the case use of containers with pressurized liquid. Thanks to the non-return valve, only the first tube is used for the flow of the liquid. If during the racking, the pressure in the container decreases, the non-return valve lets the gas into the container to be able to continue the racking.
  • the shutter means achieving the hermetic sealing of the orifice around the two tubes consists on the one hand in a flexible piece, tightly surrounding the two tubes and having a dimension greater than the orifice of the container and on the other hand into a locking device in the position of said flexible piece on the outer edge of the orifice.
  • the two tubes and the flexible part form a one-piece assembly, made of flexible plastic, preferably silicone.
  • this one-piece assembly can thus be easily replaced after each use or washed and sterilized if very hygienic push is necessary.
  • the two tubes have a section in the form of a flattened circle of internal section of the order of 50 to 80 mm 2 ; the reduced section of the second tube is of the order of 3 to 5mm 2 over a height of 2mm; only the second tube has a portion intended to be inside the container, of the order of 8 to 12mm, the first tube has a portion intended to be outside of the container, which is of the order of 1 at 5mm greater than that of the second tube and the total height between the outer portion of the first tube and the inner part of the second tube is of the order of 50 to 60mm.
  • the locking device in position of the assembly consisting of the flexible part and two tubes have two elements cooperating with each other, a first gripping element on the flange and bearing element on the flexible part, provided with at least a gripping surface and a second element. These two elements are movable relative to each other between a first position where the grip surface is in withdrawal, allowing the introduction of the locking device around the neck of the bottle, beyond the flange, and a second position where the grip surface, under the action of the second element, is advanced, and applies to the face of the collar opposite the outer edge of the neck and where the outer edge of the neck is force applied to the flexible part.
  • the closure means has two arms with a bent end which are pivotally mounted relative to an axis located in the plane of symmetry of the two tubes and a spring disposed between the two said arms.
  • the bent ends of the two arms are angularly spaced from each other, while the parts of said arms located opposite to said bent ends with respect to the pivot axis are force applied to the two tubes, thanks to the action of the spring.
  • position active i.e. when the user brings the two bent ends together two arms, thus acting against the spring, the two arms pivot around the pivot axis freeing the two tubes.
  • the inactive position the two tubes are crushed and the liquid cannot flow, while in the active position, the two tubes return to their original shape, freeing the passage of liquid and / or gas.
  • the valve of the invention is particularly intended to be placed on the neck of a large-capacity plastic bottle, for example five liters, the distribution of the liquid from this bottle requiring to return it and to put it in place on a support.
  • This tap has, so characteristic, a first flow assembly comprising two flexible tubes juxtaposed, a means of blocking this flow assembly on the neck of the bottle and a means of closing by crushing the two tubes.
  • the flow assembly 1, illustrated in FIGS. 1 to 4 consists of two juxtaposed flexible tubes 2, 3, and a flexible part 4.
  • This assembly flow 1 is preferably made of food grade silicone or in a material with equivalent flexibility. This flexibility is required when level of the two juxtaposed tubes 2, 3 which must be able to be closed by crushing, as illustrated in figures 2 and 4. It is also required when level of the flexible part 4 which acts as a seal between the device blocking and the outer edge 5 of the neck 6 of the bottle 7.
  • the first liquid flow tube 2 is completely outside the neck 6 when the assembly 1 is locked in position on the outer edge 5 of the latter.
  • return air has an inner portion 3a which extends beyond the flexible part 4 towards the interior of the neck 6.
  • the second tube 3 has an end 9, closing the inner portion 3 a which has a passage opening 10 of reduced section compared to the section of the two tubes 2, 3.
  • the two tubes 2,3 have an oblong section, each having the shape of a flattened circle (FIG. 3), of internal section of the order of 50 to 80 mm 2 .
  • the total height between the end 9 of the second tube 3 and the outer end 2 b of the first tube 2 is of the order of 50 to 60 mm.
  • the passage opening 10 of the end 9 of the second tube 3 is a circular orifice 2 to 2.5 mm in diameter, said end 9 having a thickness of the order of 2 mm.
  • tubes 2,3 which have an identical cross section over their entire length. In practice, it may be advantageous to provide some increase in this section since their inner end 2a until their outer end 2b, for release purposes when it is a single piece.
  • the two tubes 2, 3 are closed by applying against the walls rectilinear 11, 12 of the two tubes 2, 3 a certain pressure so as to achieve flattening said walls 11, 12 against each other in accordance with the representation of figure 4.
  • liquid flows through the first tube 2 while air enters the bottle through the opening 10, replacing the liquid that has passed. Possibly, in the event of a significant pressure variation at inside the bottle, liquid can also escape through port 10 flow until the pressure returns under normal conditions.
  • Figure 5 is illustrated the locking device in the workpiece position flexible on the outer edge 5 of the neck 6 of the bottle 7, said neck 6 being provided with a recessed flange 15 - sometimes called a counter ring - by compared to thread 14.
  • This type of flange 15 is used in particular for conveying bottles from blowing to capping after filling.
  • the locking device 13 consists of two elements cooperating with each other, namely a first gripping and support element 16 and a second locking element 17, both of annular shape, with the first element 16 arranged concentrically and inside the second element 17.

  • the flexible part 4 of circular shape has at least a projection 93, and the shoulder 19 has a groove, shaped to allow the nesting of said protuberance 43. It is also possible to obtain a precise placement of the flexible part 4 in the first element 16. This placement is very important when the two tubes 2,3 have a non-circular section, for oblong example, and that it is a question of positioning them in a device of closing by crushing of the two tubes.
  • the first gripping element 16 has a prominence 20, mushroom-shaped, projecting from the side and other of an annular wall 21, thus delimiting two bearing surfaces 22, 23, the first surface 22 being turned towards the inside of said first element 16 and the second 23 being turned outward, that is to say towards the second element blocking 17.
  • the annular wall 21 has a first portion 24 having a constant diameter determined D and a portion 25 ending in the prominence 20 having a diameter greater than D.
  • the portion 25 is in fact made up of individual tongues 29 integral with the first portion 24 and forming overall a frustoconical volume, in normal position, each tab being inclined by an angle ⁇ .
  • the second support element 17, annular has a diameter just greater with the aforementioned diameter D, so as to be arranged around and in the immediate vicinity of the external face of the annular wall 21 in its first portion 24.
  • Figure 5 there is shown the position of the second element 17 by relative to the first element 16 when the blocking device is put in place 13 on the neck 6 of the bottle.
  • the diameter of the neck at the flange 15 is such that it was possible to penetrate said neck as well as the collar 15 in the interior recess of the first element 16, the second element 17 being against the first portion 24 of the annular wall 21 with its upper edge 28 against the base of the tabs 29.
  • the second return tube 3 of air is slightly shorter by 3 to 4 mm, compared to the first tube 2. This arrangement allows automatic re-priming of the liquid distribution thanks to unlike the lift height in the two tubes.
