BAYONET SPOUT WITH GUIDE SHIELD AND PIERGING PORTION Filed May 15, 1964 INVENTOR CLHRENCE J. KOEHLER,Jn

AT'TORNEKS United States Patent 3,258,168 BAYON ET SPOUT WITH GUIDE SHIELD AND PIERCING PORTION Clarence J. Koehler, Jr., Midlothian, Ill., assignor to Continental Can Company, Inc., New York, N.Y., a corporation of New York Filed May 15, 1964, Ser. No. 367,804 13 Claims. (Cl. 22288) This invention relates to a novel bayonet spout for opening motor oil cans and is particularly characterized in the provision of an inverted blade constructed to prevent the piercing of the can body during the opening thereof yet insures a tight fit with minimum leakage, and simultaneously provides ease of removal of the bayonet spout after the contents of the can have been dispensed.

It is an object of this invention to provide a novel bayonet spout particularly adapted for opening motor oil cans having composite body walls, the spout including a spout body of a generally tubular construction having an outlet end portion and an inlet end portion, a guide shield extending beyond the inlet end portion, a piercing portion overlying the guide shield, the piercing portion having a piercing point directed away from the end portion of the spout body, and the piercing portion including a cutting edge sloping from the piercing point toward the guide shield and terminating closely adjacent thereto thereby spacing the piercing point a substantial distance from the guide shield and generally preventing the piercing of a composite body wall of a motor oil can to which the bayonet spout is attached.

A further object of this invention is to provide a novel bayonet spout of the type just described in which the piercing portion includes means for insuring a tight fit with a minimum of leakage when the bayonet spout is properly seated upon and secured to the oil can, and further. including means for readily and unobstructively withdrawing the piercing portion from an opening in an end wall of the can to which the spout has been seated.

A further object of this invention is to provide a novel bayonet spout including a spout body of a generally tubular construction having an outlet end portion and an inlet end portion, a guide shield extending beyond the inlet end portion and underlying a piercing blade similarly projecting beyond the inlet end portion of the spout body, the blade being of a generally inverted U-shaped configuration, a bight wall portion of the blade terminating in a piercing point directed away from the inlet end portion of the spout body and spaced a substantial distance above the guide shield, and side wall portions of the inverted U-shaped blade being impressed inwardly to permit the ready and unobstructive withdrawal of the blade from an opening in an end wall of a can into which the bayonet spout has been once seated.

A further object of this invention is to provide a novel bayonet spout 0f the type described above and including channel means to either side of the side walls of the blade and an opening in the bight wall thereof whereupon free flow of liquid from the can through the spout body during a delivery operation is achieved.

Still another object of this invention is to provide a novel bayonet spout of the type described above including stop means for accurately positioning and locating the bayonet spout relative to a can with which the spout is associated, and the bight wall or bight portion of the blade having a shallow convergent angle relative to the guide shield for assuring a tight fit between the bayonet spout and the associated can.

A further object of this invention is to provide a novel bayonet spout as described above and including a high capacity overflow cup at the inlet end portion of the spout body which is cooperative with the channels to prevent oil spillage at such times as the bayonet spout is not fully seated upon the associated can.

With the above and other objects in view that will here inafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawing.

In the drawing:

FIGURE 1 is a fragmentary top perspective view of a novel bayonet spout constructed in accordance with this invention, and illustrates the bayonet spout secured to a motor oil can.

FIGURE 2 is an enlarged fragmentary sectional view taken along line 22 of FIGURE 1, and illustrates a blade or piercing portion of the spout projecting through an opening in an end wall of the can and a piercing point of the blade portion spaced a substantial distance from the can wall.

FIGURE 3 is a fragmentary sectional view taken along line 3-3 of FIGURE 2, and illustrates a channel defined between side walls of the blade portion and an overflow cup portion of the spout.

FIGURE 4 is a fragmentary view taken along line 4-4 of FIGURE 2, and illustrates an opening in a bight portion of the wall for delivering liquid from the can therethrough during a delivery operation.

FIGURE 5 is a fragmentary sectional view taken along line 55 of FIGURE 2, and clearly illustrates impressions in the side walls of the blade portion for facilitating tight sealing engagement between the 'blade and the opening formed in the can end wall.

A novel bayonet spout constructed in accordance with this invention is generally designated by the reference numeral and comprises a spout body 11 which is preferably constructed from an upper body portion 12 and a lower body portion 13 secured together by substantially identical diametrically opposite longitudinal seams 14. The spout body 11 of the bayonet spout 10 includes an outlet end portion 15 and an inlet end portion 16.

Side Walls 17 and 18 of the inlet end portion 16 flare away from each other (FIGURES 3 and 4) to define with a similarly flaring top wall 20 a high capacity overflow cup portion 21 (FIGURE 1) which functions in a conventional manner to insure against oil or similar liquid spillage when the bayonet spout 10 is not fully seated upon or secured to a can C in a manner to be described more fully hereafter.

Each of the walls 17 and 18 is provided with an identical slot 22 (FIGURES 1 and 2), contoured to the general cross-sectional configuration of a seam S securing an end wall or panel B of the can or container C to the body B thereof (FIGURE 2). The slots 22 receive and engage the seam S in a manner clearly illustrated in FIGURE 2 to form stop means which limit the entry of a blade or piercing portion 23 into the can C, as is illustrated .in FIGURE 2 of the drawing. A shallow, generally concave guide shield 24 projects endwise from the inlet end portion 16 a distance corresponding to the end'wise projection of the blade portion 23. The guide shield 24 is contoured generally to the cross-sectional configuration of the can body B, as is best illustrated in FIGURE 5 of the drawing.

The blade or piercing portion 23 is of a generally inverted U-shaped cross-sectional configuration (FIGURE 5) and includes a bight portion or wall 25 and a pair of side walls or legs 27 and 28. The side walls 27 and 28 include respective cutting edges 30 and 31 which slope gradually from a piercing point 32 of the blade 23 toward the guide shield 24 at the inlet end portion 16 of the 3 bayonet spout 10, as is best illustrated in FIGURE 2 of the drawing with respect to the side wall 28.

Substantially midway between the piercing point 32 of the blade 23 and an opposite end portion 33 thereof secured to the overflow cup portion 21 by a bolt 34 and an elongated nut 35, the side walls 27 and 28 are depressed or recessed inwardly toward each other (FIG- URES 3-5) to define central wall portions 37 and 38 respectively which open concavely away from each other. The recessing of the portions 37 and 38 of the respective side walls 27 and 28 allow the blade 23 to be easily and readily removed from an opening (FIGURE 2) in the end wall E of the can C.

The blade portion 23 of the bayonet spout 10 is provided with a substantially rectangular opening 40 (FIG- URES 3 and 4) formed in the bight portion 25 thereof. The opening 40 is partially defined by identical cut-away portions 41 in each of the side walls 27 and 28, as is best illustrated in FIGURE 2 of the drawing. The opening 40, including the cut-away portions 41, permits the rapid flow of liquid, such as oil, in the interior of the can C through the blade portion 23 and into the inlet end portion 16 of the spout body 11.

In addition to the rapid flow of liquid through the opening 40 in the manner just described, the blade portion 23 of the bayonet spout 10 is provided with channel means 47 and 48 to either side of the blade portion 23 at the opposite end portion 33 thereof. As is best illustrated in FIGURES 3 and of the drawing, the channel means 47 lies between the side wall 17 of the inlet end portion 16 of the spout body 11 and a connecting web portion 50 of the blade side wall 27 lying between the impressed side wall portion 37 and the end portion 33. The channel 48 is similarly defined between the side wall 18 of the inlet end portion 16 and a similar web 51 of the blade side wall 28 between the impressed side wall portion 38 and the opposite end portion 33. The channels 47 and 48 thus direct any liquid which leaks be tween the opening 0 in the end wall E of the can C and the webs 50 and 51 directly into and through the inlet end portion 16 of the bayonet spout 10. If, for any reason, the bayonet spout is not fully seated upon the can C or the opening 0 is irregular or deformed, any surplus liquid which tends to accumulate in the overfl'ow cup portion 21 (FIGURE 1) of the bayonet spout 10 is directed into the tubular body 11 thereof through the channel means 47 and 48, thus insuring against spill-age when the spout 10 is not fully seated upon the can C.

During a typical operation or use of the bayonet spout 10, the guide shield 24 is positioned adjacent to or in contact with the seam S of the can C after which downward force, as viewed in FIGURES l and 2 of the drawings is applied to the tubular body 1 1 of the spout 10 to force the piercing point 32 into the end wall E.

' It should be particularly noted that the piercing point 32 pierces the end wall E of the can C at a point remote from the seam S. This piercing of the end wall E is extremely desirable in the case of cans having body walls, similar to the body wall B which are of a composite construction i.e., paperstock or similar material lined with aluminum, plastic or other fluid-tight materials. Such composite body walls tend to be pierced by the piercing points of conventional bayonet spouts which are positioned closely adjacent conventional guide shields, such as the guide shield 24 of this invention. However, the substantial spacing between the piercing point 32 and the guide shield 24 of the bayonet spout 10 substantially precludes the inadvertent or accidental piercing of the body wall B during the entry of the blade 23 into the interior of the can C.

As the bayonet spout 10 is further introduced into the interior of the can C, the cutting edges 30 and 31 of the blade side Walls 27 and 28, respectively, sever the end wall E to form the opening 0 and urge the material M removed therefrom toward the body wall B of the can C. The insertion of the blade 23 into the interior of the can C continues until the overflow cup portion 21 is seated against the end wall E (FIGURES 1 and 2) and the seam S of the can C is received in each of the slots 22 of the side walls 17 and 18.

The can C is inverted from the position thereof illustrated in FIGURES 1 and 2 of the drawing to deliver the liquid (not shown) such as oil, in the can C through the spout body 11 and the outlet end portion 15 in a manner well known in the art. After the delivery operation is completed, the can C is again positioned as shown in FIGURES 1 and 2 and force is applied to the spout body 11 to withdraw the same upwardly as viewed in FIGURES 1 and 2 of the drawing. The withdrawal of the bayonet spout 10 is facilitated by the impressed portions 37 and 38 of the respective blade side walls 27 and 28 which, in effect, converge toward each other away from the web portions 50 and 51 to ease the withdrawal of the blade 23 outwardly of the opening 0. During this withdrawal the removed material M ceases to bear against the side wall edges 30 and 31 of the blade 23 to also ease in the withdrawal or removal of the blade 23 from the can C.

In addition to the noted construction of the side walls 27 and 28 of the blade 23 to allow the easy removal of the blade from the can C, the bight portion or wall 25 of the blade 23 is also inclined slightly at an angle no greater than 5 degrees toward the guide shield 24 in a direction away from the inlet end 16 of the spout body 11, as is best illustrated in FIGURE 2 of the drawing. This angle of inclination A of the blade 23 assures a progressively tighter fit the deeper the blade 23 is inserted in the can C and consequently a relatively easier withdrawal the more the blade spout 10 is withdrawn from the can C.

At this time, it is pointed out that if it is so desired, in lieu of the elements 34 and 35 securing the blade 23 to the spout body 11, the blade 23 can be constructed as an integral part of the member 12. The operation of the bayonet spout would, however, remain substantially the same upon such a reconstruction as that heretofore described in the consideration of the bayonet spout 10.

From the foregoing, it will be apparent that the bayonet spout disclosed herein will operate to properly open cans without piercing the body walls thereof, permit the rapid delivery of liquid therefrom and facilitates the ease of removal of the spout from a can to which the same is secured.

From the foregoing, it is believed apparent that novel and advantageous provision has been made for carrying out the desired end. However, attention is directed to the fact that other variations may be made in the example pouring spout disclosed herein without departing from the spirit and scope of the invention as defined in the appended claims.
