Definitions

• Flexible pocket support and dispenser comprising such a support.
• the present invention relates to a flexible pocket support intended to be mounted in a fluid dispenser comprising a flexible pocket in which the product to be dispensed is stored.
• a dispensing device such as a pump or a valve.
• the dispensing device is preferably a device of the type without air intake or "airless" in which the product is extracted without introducing air, so that the volume of the flexible bag decreases as the product is dispensed.
• This intermediate piece is here called flexible pocket support because it is on this piece that the opening of the flexible pocket is generally fixed by welding.
• the support defines a structure on which the dispensing device or dispensing member is mounted. The support then defines a passage communicating the dispensing member with the opening of the flexible bag to allow the extraction of the fluid contained in the bag.
• the dispenser described in document WO 93/25321 comprises a flexible pocket provided with a dip tube fixed in a connection sleeve which also defines the passage making the inside of the pocket communicate with the outside.
• the fluid can thus reach the passage of the support either directly along the tube, or through the interior of the tube in case a compartment is formed in the pocket.
• the tube therefore has a draw-off function making it possible to extract the fluid contained in a compartment of the pocket
• the tube is directly disposed in the passage.
• the object of the present invention is to remedy this drawback of the prior art by defining a pocket dispenser with an easily refillable dip tube.
• the present invention provides a flexible pocket support as defined in claim 1.
• said appendage is formed with at least one fixing end fitting adapted to come into engagement with the upper end of the tube.
• said fixing endpiece communicates with the passage through at least one window located beyond the upper end of the tube.
• said fixing end piece communicates with the passage by means of a conduit extending in the extension of said end piece and opening into the passage.
• the upper end of the tube is forcibly engaged on said end piece.
• said at least one tube is fixed with its upper end out of the passage in the immediate vicinity of the latter.
• FIG. 1a is a cross-sectional view through a flexible pocket support according to the invention
• FIG. 1b is an alternative embodiment of FIG. La
• - FIG. 2 is a view from below of the support for pocket of Figure la
• Figure 3 is a vertical cross-sectional view offset 90 ° from that of Figure la
• Figure 4 is an enlarged representation of a detail of Figure 3.
• the pocket support flexible according to the invention which is designated as a whole by the reference numeral 1 is preferably made by molding of plastic material.
• the flexible pocket support 1 is provided with a sleeve 12 used for mounting a pump or a valve.
• the pump can be fixed on the bush 12 by means of a ring adapted to snap onto the bush 12 while holding the pump or the valve on the bush.
• the support 1 defines a passage 13 extending through the sleeve 12 and the appendix 11 as can be seen in FIG. This passage makes it possible to communicate the inlet of the pump or of the valve mounted on the socket 12 with the opening of the flexible pocket welded to the appendix 11.
• the support 1 can be provided with a peripheral flange 10 can be used to fix the support on a rigid shell enclosing the flexible bag.
• the support 1 is provided with a tube 2 intended to extend inside the flexible bag.
• the tube 2 is open at these two ends and defines inside a conduit 20 through which the fluid can flow.
• the tube 2 comprises a lower end 21 located inside the flexible bag, preferably in the vicinity of the bottom of the bag and an upper end 22 connected to the support 1.
• the conduit 20 communicates with the passage 13 directly or indirectly with no possibility for the pocket to cut or close this communication.
• the tube 2 extends eccentrically relative to the passage 13, so that it is located outside the passage, leaving the latter perfectly free for filling the pocket. Indeed, the tube 2 is fixed to the support 1 at the level of the appendix 11 on a nozzle 14 formed near the lower opening of the passage 13.
• the nozzle 14 is in the form of a connection sleeve on which can be engaged the upper end 22 of the tube 2 for example by force, and further comprises one or more windows 15 located above the upper end 22 of the tube 2, the said window or windows communicating directly or indirectly with the passage 13.
• the sleeve 14 of the fixing end piece can communicate with the passage 13 by means of a conduit 15a extending in the extension of said sleeve and opening laterally into the passage 13.
• the method of fixing the tube to the support 1 is not critical for the invention in the sense that any fixing technique can be used to secure the tube 2 to the support 1.
• any fixing technique can be used to secure the tube 2 to the support 1.
• the spirit of the invention resides in the fact of using a tube which communicates with the passage 13 without the possibility for the flexible pocket to come to cut this communication, so that the lower end 21 of the tube 2 can reach areas of the pocket in which sealed compartments can form.
• this tube must not obstruct or clutter the passage 1 for the purpose of filling the bag.
• a flexible pocket support comprising several tubes 2 as can be seen in the figures where there are provided two fixing ends on the same pocket support 1 located on the side and on the other side of the passage.
• the fluid contained in the flexible bag can thus reach passage 13, either directly, for example along the tube 2, or indirectly through the tube 2 which communicates with its upper end 22 with the passage 13.
