Description
Patented Apr. 4, 1939 UNITED STATES PATENT- OFF-ICE mesne assignments, to James P. Hume, Chicago,
Application August 19, 1936, Serial No. 96,766
3 Claims.
' other to withstand the strains of rough-handling and abuse.
Another object of the invention is to provide a bung connection which will permit the inclusion of an exterior embossment in the container wall around the fitting without leaving exposed on the inner side of the wall the complementary depression of the embossment, which would serve to trap some of the container contents and prevent complete draining.
A further object of the invention is to provide a bung fitting design wherein means to which the closure plug is arranged to be anchored to prevent unauthorized turning or removal thereof, is secured directly and preferably exclusively about a part of the fitting proper rather than to or about a part separate of the fitting such as a portion of the container wall.
The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and-description may be adopted within the scope of the invention as set forth in'the claims.
Referring to said drawing:
Figure 1 is a plan view of the fitting as applied to a container.
Figure 2 is a fragmentary bottom view of structure illustrated in Figure 1.
- Figure 3 is a longitudinal sectional view of the fitting taken on the line 3-3 of Figure 1, a portion of the-fitting being shown broken away to reduce the size of the figure.
Figure 4- is a plan view of the fitting applied to the container wall in an inverted relation.
Figure 5 is a sectional view similar to Figure 3, but taken on the line 5-5 of Figure 4.
In the embodiment of the invention illustrated in Figures 1 to 3, the fitting includes a bushing 2 extended through an opening 3 of a container wall 4 and threaded internally for the reception of a suitable closure plug. Formed at one end the of the bushingis a relatively large transverselyextending flange 5 which is positioned on the outer side of the wall and seats within a depression defined by an embossment 1 formed in the wall and conforming in general with the outer perimeter of the flange. Since the latter is here 5 shown circular, the embossment is formed correspondingly and raised on the exterior of the wall to an extent approximating the protrusion of the flange from the general plane of the wall. With this arrangement the edge of the bushing 10 flange is protected by. the embossment and in fact, each part protects the other.
On the inner side of the container wall and surrounding the opening 3 is backing member 8 between which and the flange 5 the wall is 15 firmly gripped. The inner end of the member 8 is formed to provide a collar 9 which is, in part, coextensive longitudinally with the bushing and embraces the side walls or body l2 thereof. The member 8 is held against the container wall by means of a flange I 3 provided at the inner extremity of the bushing and rolled over the adjacent extremity of the member. Rotationaldisplacement of the member 8 with respect to both the container wall and the bushing is prevented by means of a plurality of circumferentially spaced protrusions it formed in the flange 5 and engaging in offsets IS inthe container wall, and which in turn, engage in offsets I! in the backing member, the offsets being preferably initially formed as the parts are clamped between the two flanges of the bushing during the assembly of the fitting parts and the application thereof to the container wall.
The portion l8 of the backing member against the container wall is made large enough to more or less completely lap the embossment and in order to provide a direct reenforcement for the embossment, the outer peripheral portion of the member is formed with a folded edge l9 which is extended into the embossment cavity and bears against the sides thereof. It will be evident that since the edge portion i9 engages with the walls of the embossment cavity for the entire circumference of the backing member, a full and complete reenforcement of the member is afforded. The reenforcing effect between the member and the container wall is further emhanced by reason of the fact that the portion of the wall engaged by portion N3 of the member is ofi'set so as to enable the latter to lie coplanar with the portion of the wall at the outer periphery of the embossment. This design and relationship of the parts, as aforesaid, provides an important additional advantage in that notwithstanding the provision of the embossment and the relatively large recess thereby formed on the inner side of the container wall, the portion ii of the member including the rim i9 thereof will cover the recess and depressed portion and thus prevent any trapping of the plied to the container in reverse relation to that in which it is shown in Figures 1. to 3. By thus reversing the fitting, the flange 5 will been the inner side of the container wall while the backing member and, the greater portion of body i2 will be disposed on the outer side of such wall. With this arrangement, the embossment i being formed by depressing the container wall inwardly,
the backing member and bushing may be used as in the first described embodiment and thus all of the reenforcing qualities due to the cooperation and formation of the parts, are retained. When the fitting is applied as in Figure 4, the backing member lends itself particularly well for use as a means for anchoring or scaling in place the usual threaded plug 2| serving as a closure for the opening through the bushing 2. Heretofore it has generally been the custom to anchor the plug directly to the container wall, but such practice is disadvantageous since it usually entails mutilation or deformation of the container wall. By having the plug anchoring or sealing means confined essentially to the backing member, the provision of such means for the fitting becomes, for the most part, a mere element in the initial formation of such member. As here shown, an anchoring point on the member is provided by pinching a portionof part l8 of the member so as to provide a boss-like projection 22. The latter is formed with openings 23 through which may be threaded the sealing wire 21 which is attached to the plug, the wire, as will be understood, being twisted and sealed after being threaded through the boss so as to prevent unauthorized rotation of the plug and access to the container contents by way of the opening through the fitting. It is also important to note that the anchoring means as provided for in my fitting forms a direct appurtenance of the bushing, since, as will be noted, the member l2 has a direct contactual embrace with the bushing and is secured thereto at least in part entirely exclusively of the container wall. This feature is important for the reason that irrespective of any impairment of the bond between the member and wall, the plug sealing or anchoring function will not be affected.
As a means of anchoring the plug, where the fitting is applied as shown in Figures'l to 3; the flange 5 of the bushing is formed with a perforated lug 25 which is positioned so as to over-lie a slightly depressed portion 25 of the embossment.
