The present invention relates to scaling members for containers and to containers provided with such sealing members.
An object of the present invention is to provide a form of sealing member which permits the eflicient sealing of a liquid container having, for filling the container, an aperture of very simple form.
A further object of the present invention is to provide a sealing member for use with such a. container which sealing member incorporates a pourer or a fluid delivery valve.
The necessity to provide eflicient means for sealing containers for liquids has hitherto rendered it necessary to provide the containers with filling apertures of complex form and has thus rendered the containers expensive to manufacture.
. For example, the apertures of containers of the can type are provided with necks adapted to cooperate with such sealing members as plugs, screw caps or snap csures. The provision of such necks, however short, not
only renders the containers the more diflicult to manufacture but in practice renders them less durable in use. This is because although it is commercially practicable to provide containers in which the main body is coated With a thin layer of lacquer or other protective finish it is not feasible to provide a similar coating uponrthe neck. Even if the neck is fabricated from sheet material which has been given a protective coating, the coating cannot be maintained intact during fabrication of the neck and no really cheap method of coating the finished neck has/been evolved. Consequently, although the main bodies of containers of the can type usually have a substantial resistance to corrosion, this is not true of their necks which accordingly tend to corrode thus spoiling the contents and rendering the containers prematurely useless. Various attempts have been made to avoid the necessity to provide containers with necks but these attempts have so far proved unsuccessful since it has been impossible heretofore to provide sufliciently cheap and convenient sealing members which can seal simple apertures efliciently. p
In accordance with the present invention there is providcd a sealing member for a container Which comprises a plug of rubber or other elastomeric material formed With a pair of surrounding flanges whose adjacent surfaces are spaced apart in the axial direction of this plug to define a groove whose Width in the axial direction of the plug is small, in comparison with the peripheral size of the plug at the groove, the first of the flanges (a) being formed over at least a part of its axial length with a surface jwhose peripheral size" increases in the direction of the groove,
i (b) beingof-maximum peripheral size adjacent to the groove, 1
(c) having a minimum peripheral sizewhich is, at most, substantially equal to the peripheral size of the plug at the groove, and V a -(d) having a maximum pe "pheral size which is in Patented Apr. 18, 1961 an a suflicient to prevent (and preferably just allows) sufiicient deformation of the plug and the first flange to allow passage of the first flange through an aperture leading from the outside to the inside of a container, which aperture has a peripheral size which is substantially equal to that of the plug at the groove and an axial length substantially equal to said width of the groove until the first flange is located Within the container.
The invention will be understood from the following description in which reference is made to the accompanying drawings. I
In the drawings:
Figure l is a vertical sectional view and Figure 2 is a top plan, of part or" a container sealed by means ofa sealing member having a liquid delivery valve positioned therein, according to the present invention,
Figure 3 is a cross section taken on line III-III of Figure 2, V
Figure 4 is a cross section of a sealing member incorporating an invaginable pourer.
' Figure 5 is a cross section of a sealing member incorporating a pourer of another type from that shown in Figure 4.
The can shown in Figures 1, 2 and 3 is a four gallon can of square cross section formed of lacquered tinplate and having a side wall 1 seamed to an upper wall 2 and a lower wall 3. The upper and lower walls are recessed as shown most clearly in' Figure 3 to such an extent as to accommodate the handles; when a plurality of cans of the type shown are stacked compactly together.
Near one corner of its upper wall, the can is foamed with a filling aperture, the metal around which is upset as shown to provide a conical seating surface 5 and a planar annular edge 6 which faces into the can. Located within the aperture is a hollow rubber plug 7 formed with a first flange S and a second flange 9 The second flange 9 covers the conical-seating surface Sand is formed at its outer periphery with adownwardly directed rim 10 which contacts the top wall of the can outside the conicalseating surface 5.
The first flange 8 is of uniform diameter over its upper portion and of uniformly decreasing diameter over its lower portion. The flange 8 terminates above-the lower end of the plug 7 to leave at the lower end'of the plug a short cylindrical section 11. Theupper surface of the first flange 8 and the lower surface of the second flange 9 are constructed and spaced to define a groove, 12 whose axial length parallel to the axis of plug 7 and whose bottom diameter are suchthat' the groove snugly engages the filling aperture in the upper wall of the can with the rubber of which the plug is formed being held 'under slight radial compression. At its upper end the plug is formed with an integrally moulded drip spout '13.

a partition 19, extending transversely of'tube 14. and which closes the tube14 near its upper end, and a button 20 which is linked with the rubber valve plate17 V by a valve rod 21/ Just below the partition 19 extending transversely of tube 14 is a further partition 22 which is formed with an airway 23 adjacent to the wall .of the tube. A liquid .delivery' port 24 and an air inlet'port 25 are formed through the longitudinal Wall of the tube--14 adjacent to the upper and lowersides. respectively of the partition 1 22diarnetrically opposite the airway 23.:
