Abstract 1,168,464. Tapping containers; stoppers; bunghole bushes; venting containers. C. H. MALPAS. 14 Nov., 1966 [19 Nov., 1965; 29 Nov., 1965], No. 50986/66. Headings B8T and B8X. A liquid container, provided with a tapping socket 34 into which a tap 27 may be fitted, is vented after cutting off the top of a hollow plug 26 fitted within a collapsed air bag 32 so that the upper wall of the bag surrounds the plug. In place of a vent plug the bag may be attached to a tube secured in the container wall; or the vent plug may have a through passage, Fig. 3 (not shown) sealed only by the bag wall at its upper end. The plug 26 may have a filter or an inlet valve. The container may be of tinplate and sprayed internally with lacquer. The bag may be of polypropylene with or without a coating of " Saran " (Trade Mark) or of polyethylene which may be similarly coated; or an inner bag of air-impervious material may be enclosed in an outer bag compatible with the liquid, e.g. milk or wine, in the container. Tapping.-A pair of holes in the container wall receives the socket 34 and locating plug 35 respectively, Fig. 5 (not shown). A plug, protecting a diaphragm (36), is removed and the tap, Fig. 9, inserted until held within the container wall by a bead on the inner end of a neck 43. An apertured cylindrical portion 47 is rotatable by a finger piece 50 to align it with a spout 41, thereby drawing off the liquid. The socket 34 may have slits (55), Figs. 6-7 (not shown), through which arms (60) on the protecting plug pass to provide a tamperproof closure. The socket may be held non-rotatably in a square hole in the container wall and itself similarly hold a square flange on the tap, Figs. 10-12 (not shown).
