Dec. 15, 1936. H. A. FINK FRICTION TOP CAN Filed Marh 23, 195e in SS!!! Maggi Patented Dec. 15, 1936 UNITE-D STAT Es vPATENT OFFICE Application March 23, 1936, Serial No. 70,509
The invention relates to new and useful improvements in a friction top can of the type wherein a nozzle is provided through which the contents may be dispensed, which nozzle may be closed by a friction cap.
An object ofthe invention is to provide a nozzle for a can of the above type which is connected to the can end close tothe side edge of the can and in such a way as to provide a relatively free pouring surface at the inside of the can in the region of the nozzle so as to avoid any trapping of the liquid content of the can during dispensing.
A further object of the invention is to provide a can of the above type with a friction closure cap which is adapted to engage over the upper portion of the nozzle for protecting the same durlng shipment and for reclosure purposes when the seal of the can has been broken for dispensing the contents thereof.
A still further object of the invention is to provide a can of the above type wherein the nozzle is formed from a single piece of drawn metal, and wherein the outer end of the nozzle is scored close to the edge thereof to facilitate a rupturing of the metal to break the seal of the can for dispensing purposes.
In the drawing- Figure 1 is a view showing partly in side elevation and partly in section a can embodying the improvements;
Fig. 2 is a plan view of a portion of the can;
Fig. 3 is 'an enlarged sectional view showing the can end and the nozzle assembled preparatory to the clinching of the interengaging hooks for the seaming of the nozzle to the can end, and
Fig. 4 is a view similar to Fig. 3, but showing the nozzle fully seamed to the can end.
In the present illustrated embodiment of the invention, the can includes a body portion I to which a bottom end 2 is seamed. A top end 3 is also secured to the body portion I by a double seam 4. This top end has an opening formed therethrough relatively close to the side edge of the can. The metal surrounding the opening is rst bent downwardly to provide an annular hook portion 5. A nozzle 6 is drawn from a single piece of metal so as to provide a cylindrical wall 1 closed at the outer end by an integral portion 8 which is scored at 9. The score line is located close to the vertical wall 'I and extends all the way around except for a small section which is sufficient to support the part which is to be ruptured and torn away so that it will not drop into the can. When the metal is ruptured along the score line an (or 22o-44s) opening will be provided which is of substantially the same diameter as the inner diameter of the nozzle. vBy forming the score line close to the inner wall of the nozzle, a nozzle Amay be used which is relatively4 small in diameter and at the same-time providea f-ree pouring/opening through which the contents may be dispensed. With this relatively small nozzle having an unobstructed pouring opening, the surface over which the contents flows is relatively narrow, which is of great advantage in dispensing the contents of the can. The nozzle at the lower end thereof has an outwardly extending flange I0 which is bent upwardly at its outer end to provide an annular hook I I adapted to engage the hook 5 on the can end.
After the nozzle has been assembled inthe can end as shown in Figure 3, it is then subjected to a bumping operation for locking the hooks together as shown in Figure 4. During this bumping operation it is noted that the hook II on the nozzle is turned to a position so that it lies in a plane parallel kwith the plane of the can end. Likewise, the hook 5 on the can end is turned into a plane which is parallel with the plane of the can end. During this bumping operation, the metal of the can end is offset upwardly, and this together with the positioning of the hooks, places the lower surface of the ange of the nozzle in alinement with the inner surface of the can end. The raw edge of the metal of both the can end and the nozzle are concealed within this seam which joins the nozzle to the can end.
It will be noted from the above that a onepiece nozzle of simple construction is attached to the can end by a seam which leaves little or no projecting portion at the inner side of the can, and therefore, when the can is turned to a position for dispensing the contents thereof, there will be little or no trapping of the contents. When the nozzle is positioned close to the side edge of the can, this also aids in the complete emptying of the can through the nozzle.
A friction cap I2 is provided, which cap is drawn from a single piece of metal. The cap is dimensioned so as to engage over the nozzle and make tight frictional contact therewith. The lower edge of the cap I2 is curled outwardly and upwardly as indicated at I3. The depending skirt of the cap is of such length as to permit the cap to lit tight against the upper end of the nozzle. The cap is placed on the nozzle and protects the scored end of the nozzle from blows which might rupture the metal along the score line. Inasmuch as the cap engages the outer surface of the nozzle, the end of the nozzle may be closed and scored as described, and furthermore, a relatively small nozzle may be used and placed close to the side edge of the can. It is noted that the nozzle extends only slightly above a plane containing the upper edge of the double seam. This is suicient to enable the contents to be poured from the nozzle without contacting with the double seam, and at the same time, the nozzle is well protected when the cap is applied thereto during shipment and handling of the can. When it is desired to open a can, the nozzle is removed and the metal ruptured along the score line. This produces, as noted above, a pouring opening which is substantially the full size of the inner diameter of the nozzle. The can may be re-closed by placing the cap on the nozzle, and through the frictional contact of the cap with the nozzle, a comparatively tight reclosure seal can be obtained.
Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is-
A friction top can comprising a body portion, an end seamed to said body portion and having an opening therethrough adjacent the side wall of the can, the metal of the can end surrounding the opening being turned back to form an annular hook which is substantially parallel to the plane of the end, a nozzle formed from a single piece of metal, said nozzle having a cylindrical portion fitting the opening in the can end and a. closed integral outer end provided with a score line disposed adjacent the edge of the end of the nozzle so that when the metal is ruptured along the Vscore line a pouring opening is provided which is of substantially the same diameter as the inner diameter of the nozzle, said nozzle having at the lower end of the cylindrical portion an outwardly extending flange bent back so as to form an annular hook which is interlocked with the annular hook on the can end, said ange and said hook being substantially parallel to the plane of the end, said interlocked hooks being offset upwardly relative to the plane of the end so that the lower surface of the flange of the nozzle is in alinement with the under surface of the end, and a friction cap adapted to engage over said nozzle for protecting the same during shipment and for reclosure purposes after the dispensing of the contents of the container.
