J., assgnor to American Can Company, New York, N. Y., a corporation of New Jersey Application December 21, 1950, Serial No. 202,064
3 Claims.
The present invention relates to containers, and has particular reference to a friction plug container and pouring spout assembly wherein the pouring spout is adapted to snap onto the friction ring of the container without interference with the friction plug.
The friction plug container is one of the most popular types vof containers now on the market for the packaging of certain products. It is often used to hold such liquids as paints, varnishes, syrups, etc. which are poured directly from the container by the ultimate consumer. The friction ring which comprises the upper portion of the container and denes the filling and pouring opening is somewhat irregular in contour and tends to impart a. turbulence to the stream of the liquid product which makes it somewhat diflicult to direct. Then, too, the friction ring often is formed with achannel or annular recess which becomes at least partially soiled and/or lled with the product being poured unless it is constantly wiped clean.` In order to eliminate these undesirable conditions, the present invention provides a pouring spout which snaps onto the upper end of the container and carries the contents across the friction ring in a smooth, controllable stream which is never in contact with the friction ring.
An object of the invention is the provision of a small, simple, and inexpensive one-piece pouring spout which may be easily attached to or detached from a container and has an `inclined selfdraining pouring wall which assists in securing the spout to the container.
Another object is to provide a friction plug container pouring spout assembly wherein the spout conforms to the general outline of the container portion to which it is attached before filling and remains thereon without interfering with the seating or unseating of the container closure.
Numerous other objects and advantages of the invention Vwill be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.
Referring to the drawings:
Figure l is a perspective view of a friction plug container and spout assembly with the friction 1 plug closure removed;
Fig. 2 is an enlarged sectional detail taken. substantially along a vertical plane. indicated'by.
the lines 2-2 of Fig. 1, the view also showing the friction plug closure inplace on the con- Y ing of the plug closure 22.
tainer in fully seated position, parts being broken away;
Figs. 3 and 4 are sectional details similar to Fig. 2, but showing slightly modified forms of the invention, parts being broken away; and` Fig. 5 is a perspective view showing the spout as adapted for use with a rectangular container, with parts broken away.
In the preferred and exemplary embodiment of the invention, Figs. 1 and 2 illustrate a friction plug container A having a cylindrical sheet .metal body II, a bottom end member l2, and a friction ring I3 which is secured to the upper end of the body II in a projecting end seam I4 preferably of the double seam type.
The friction ring I3 (see Fig. 2) has an outer flange interlocked with a similar ange on the body to form the top seam I4 and has a countersink wall I5, which extends from the end seam Hl into the body II and along the inner surface of the body wall. Inwardly of the countersink wall I5 theimetal of the ring is bent to form a horizontal wall section I6, which merges into an upwardly inclined reinforcing wall section Il. The wall section Il curves into a downwardly directed vertical shoulder wall I8, which continues into a horizontal shoulder or offset i0 and finally terminates in a vertical friction wall 20. As can readily be seen from Figs. l and 2, the upper surface of the friction ring I3 has an irregular cross-sectional contour which includes an annular groove or channel portion 2l.
The cylindrical wall 20 serves as a friction seat for a dish-shaped friction plug closure 22 which is formed with a cylindrical friction wall 23 and a horizontal flange 24, which at its outer edge is bent back upon itself to form a curl or hem 25.
In order to facilitate easy dispensing of the containercontents, the instant invention provides a detachable pouring spout or guide bridge 30 which is adapted to snap into place on the upper end of the container A, and which, when so positioned, does not interfere with the seat- The spout 30 is arcuate in shape in order to conform to the arcuate shape of the friction ring I3 and preferably has` a length of about 90 of arc. It is formed with a smooth, gently inwardly and downwardly inclined, sloping pouring wall 3l which extends from the top. or peak of the end seam III to they top of the vertical or upright wall I8, thus bridging or spanning the channel 2l.
The inner portion of the pouring wall 3i of the spout merges or curves into a substantially vertical depending rear wall section 32 which lies flat against or frictionally engages the vertical wall I8 of the ring I3 and is spaced from and does not interfere with the friction plug wall 23 when the plug 22 is inserted to its normal seated position with its flange 24 level with or slightly below the top of the end seam I4 (see Fig. 2). The spout 30 also is provided with a resilient, substantially vertical front or outer wall 33 which preferably lies at against the outer surface of the end seam I4. The upper portion of the wall 33 merges into the pouring wall 3| and the bottom portion terminates in an inwardly-rolled resilient curl or projection 34 which engages beneath the projecting end seam I4 in substantially linear contact.
As previously stated, the spout and the container are assembled by snapping the spout over the friction ring as shown in Figs. l and 2. The inherent resiliency of the metal of the spout permits the front wall 33 to yield during this operation. The spout is so dimensioned that the curl 34 is compressed slightly as it snaps into place beneath the projecting end seam I4 and thus the seam is tightly gripped between the curl 34 and the hook portion of the spout which contacts the upper portion of the seam and top of the countersink wall at 35. With the spout in this applied position, the container may be tilted into pouring position and the contents poured over the spout as desired. The tight annular contact over a comparatively large area between the vertical walls I 8 and 32 prevents seepage of the container contents beneath the spout 30 during pouring. When the container is righted after pouring, the slope or inclination of the pouring wall 3| tends to cause any fluid which might adhere thereto to drain back into the container body.
It can be readily seen that the spout is securely attached to the container when in fully assembled position. Outward sliding movement of the spout is precluded by the contact between the vertical walls I 8 and 32 and the fact that the hook portion 35 of the pouring wall 3| slopes downwardly behind and engages against the end seam I4 and countersink wall I5, while vertical movement is checked by the engagement of the curl 34 beneath the end seam I4. There is also no possibility of the spout being inadvertently detached from the container as a result of the accidental application of pressure upwardly against the bottom edge of the vertical wall 32. Such application of pressure would tend to cause the spout to rock or pivot about a point along the line of contact between the curl 34 and the end seam I4, but, due to the arcuate shape of the spout, the portions of the curl 34 adjacent the pivot point tend to move upwardly and press against and are held in place by the seam Ill.
In the embodiment shown in Fig. 3, the vertical shoulder wall I8 is spaced from the friction closure wall 23 a distance which is substantially the thickness of the vertical spout wall 32. Thus the plug wall 23 contacts the spout wall 32 when the plug is seated on the container and locks it securely in position. This is an additional safeguard against accidental detachment of the spout due to possible rough handling during shipment.
Figure 4 illustrates another slightly modied form of the invention. In this construction the shoulder or offset I9 of Figs. l, 2, and 3 is omitted and the sloping pouring wall 3l bridges the channel 2 I and terminates in an inner edge that presses against and conforms to the ring adjacent the top of the friction wall 20. The inward and downward conical slope of the wall 3l) behind the end seam I4 prevents the spout from sliding outwardly off the container body, and the spout is restrained from any upward of rocking movement in the same manner as the embodiment of Figs. l, 2, and 3. The advantage of the construction shown in Fig. 4 is that it can be used on a standard friction plug container without necessitating any changes in the friction ring.
Figure 5 shows how the spout may be used in conjunction with an oblong container. Here the spout is substantially right-angled or L- shaped and is snapped onto a corner of the container. Apart from this change in shape, however, the spout is constructed exactly as are the embodiments of Figs. l to 4, and retains all of the features and advantages thereof.
It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
