United States Patent 3,241,731 CAPS WITH SPOUIS Wiliard M. Bright, Ridgewood, and Frederick W. Schreibcr, Fair Lawn, N.J., assignors to Lever Brothers Company, New York, N.Y., a corporation of Maine Filed Aug. 8, I953, Ser. No. 300,768 Claims. (Cl. 222---541) This invention relates to improvements in caps for containers for liquids and, more particularly, to caps with spouts having closed ends which are cut off to open the container.

A variety of liquid products are now being marketed in containers with caps having spouts with closed ends which are cut off or with open ends having secondary closures which are removed to permit the product to be poured or forced out through the small orifice of the spout. In the presently known types of such containers, the spout projects upwardly from the top of the cap and directs a stream of the product in line with the axis of the container when it is turned upside-down and pressure is applied to the relatively flexible receptacle portion.

There are a number of disadvantages of the form of caps now in use. For one thing, it is quite inconvenient to invert the container completely when dispensing the product, inasmuch as the liquid often squirts out prematurely in an unintended direction in the course of inverting the container. It has also been found that the consumer generally holds the container upright and grips it tightly when he is cutting the closed end from the spout or removing the second closure. Often, the liquid suddenly squirts out because of the pressure exerted on the container by the users grip.

Sometimes, the user is not careful to direct the spout away from his person and is sprayed with the product. Being sprayed with the product While opening the container is irksome and even angering to the user and results in the loss of the sellers product goodwill. Despite this and other disadvantages of the present types of containers having spouts with snip-off ends, their convenience and efficiency make them widely accepted.

This invention is directed toward overcoming the disadvantages of the present forms of caps with either snipoff spouts or secondary closures by providing, in accordance with the invention, a cap, which may be of any conventional screw-on type, with a spout arranged so that the liquid is directed to the side rather than vertically with respect to the vertical axis of the container.

It will be apparent that the laterally directed spouts having closed ends are adapted to be opened by cutting along a generally vertical or diagonal plane rather than in a horizontal plane. Therefore, most users will, it is believed, open them by holding the container with the axis of the spout directed to the side or away from the body and cutting with scissors which are pointed away from the body. It is very unlikely that the user will hold the scissors so that they lie parallel to his body, the wrist position enabling such an orientation of the scissor blades being quite unnatural and uncomfortable. With the scissors held and used in the usual manner, the spout will be pointed to the side and any fluid which happens to squirt out of the container will be directed harmlessly away from the users person.

In dispensing the liquid from the container, it need only be tilted over until the level of fluid covers the inside of the spout orifice. Inasmuch as the spout is directed laterally when the axis of the container is vertical, the spout will be directed generally downward when the axis of the container is substantially horizontal. Therefore, unlike the presently known types of containers having spouts which are axially aligned With the container and from ice which the contents often squirt out in alignment with the axis of the container when it is pointed horizontally or even slightly upwardly, the spout of a cap, in accordance with the invention, is pointed downwardly when the container is tilted to a generally horizontal position so that the contents are ejected downwardly.

For a better understanding of the invention, reference may be made to the following detailed description of exemplary embodiments, taken in conjunction with the figures of the appended drawing, in which:

FIGURE 1 is a pictorial view of a cap in place on a container;

FIG. 2 is a side view in section of the cap of FIG. 1 taken generally along the line 22 of FIG. 1;

FIG. 3 is a pictorial view of a second embodiment of a cap;

FIG. 4 is a view in section of the cap of FIG. 3 taken generally along the line 44 of FIG. 3;

FIG. 5 is a pictorial view of another embodiment of a cap; and

FIG. 6 is a view in section of a cap of FIG. 5 taken generally along the line 6--6 of FIG. 5.

Referring to FIGS. 1, 3 and 5, each of them illustrates a

cap

10, 10' or 10" for a container 12, each cap including a generally

flat top

14, 14 or 14" and an

annular sleeve

16, 16 or 16 which extends downwardly from the perimeter of the top. Formed in the internal wall of the

sleeve

16, 16 or 16" are

threads

18, 18 or 18" (FIGS. 2, 4 and 6) by which the cap may be screwed onto a nozzle 17 upstanding from the container 12 and having an externally threaded upper end (not shown).

Downstanding from the underside of the

cap top

14, 14 or 14" is a short, internal

annular sealing flange

19, 19' or 19" which lies concentric to the

sleeve

16, 16 or 16" and inwardly thereof and which is adapted to fit into and make a sealing engagement with the inner surface of the rim of the nozzle 17. The cap may be removed for pouring, if desired, by unscrewing and detaching it from the nozzle 17, concave depressions or

flutes

21, 21' or 21 formed on the outer surface of the

sleeve

16, 16 or 15" being provided for convenient gripping by the users fingers.

Referring now particularly to the cap shown in FIGS. 1 and 2, a cylindrical-shaped projection 20 extends upwardly from the top 14 of the cap and is preferably formed integrally therewith. The inner surface of the side wall 20a of the projection 20 forms a chamber which is in communication with the interior of the receptacle 12 when the cap is installed thereon, and with a spout 2 which projects laterally from the projection.

Inasmuch as the cap is best made by molding it from a suitable plastic, the geometry of the cap makes it more practical that the spout 24 be molded as a separate member and then be pressed into a preformed opening 22 in the wall 20a of projection 20 near its top portion 20b. In this case, the spout 24 may include

beads

26 and 28 at its juncture with the projection 20 which hold the spout 24 tightly within the opening 22. A portion 20c of the side wall Ztla adjacent the opening 22 in the projection 20 is made flat in order to provide planar sealing and engaging surfaces for the

beads

26 and 28.

The outer end of the spout 24 has a generally hernispherical closure 30 formed integrally therewith. Extending about the outer surface of the spout 24 adjacent the closure 30 is a small bead 32 which serves to guide the blade of a cutting instrument when the closure is being cut off.

It should be noted that the outermost part of the spout 24 lies within the plane defined by the outer surface of the sleeve 16. Accordingly, there are no projections which can interfere with cap attachment devices now in use.

Normally, the closure 30 of the spout 24 is cut off, preferably with scissors, along a plane defined by the inner surface of the bead 32 to open the container. However, when (l) the spout 24 is a separate member held within the opening 22 only by a tiny bead 26 and (2) the spout 24 and the projection 20 are somewhat resilient, the entire spout 24 may, when desired, be quite readily removed from the cap by grasping the exterior portion firmly and simultaneously pulling on the spout 24 and bending it to the side. The opening 22 then provides a discharge passage for the contents of the container. As previously indicated, the container may also be opened by unscrewing and removing the entire cap.

In the cap illustrated in FIGS. 3 and 4, a short, tubular spout 40 extends from the edge of the top 14'. The underside of the top 14 includes a recess 42 which lies within the sealing flange 19'. A small passage 44, extending radially through the top 14 of the cap, connects the orifice 40a of the spout 40 to the recess 42. The outer end of the spout 40 includes a closed end 46 and a small groove 48 formed adjacent thereto which defines a cutting plane along which the end 46 of the spout 40 can be severed to open the container.

In the embodiment of FIGS. and 6, a projection 60 is formed integrally with the top 14" and includes a spherical-segment-shaped portion 60a and a fiat portion 60b in which a fairly large opening 62 is formed. The fiat portion 60b intersects the top 14' at an angle of approximately 45. Installed in the opening 62 of the nipple 60 is a spout member 64, which includes an inner enlarged part 66 having a pair of spaced-apart beads 68 and 70 on its outer surface which tightly engage the flat portion 60b to firmly secure the spout 64 in the opening 62.

The outer end of the spout member 64 includes a narrow passage 72 which is approximately perpendicular to the fiat portion 60b and terminates in a closed end 73. About the circumference of the spout member 64 adjacent the closed end 73 is a bead 74 which defines a plane along which the closed end 72 may be cut off to open the container, the inner surface of the bead 74 serving to guide scissors or a knife. Like the embodiment of the cap of FIGS. 1 and 2, the outermost part of the spout 64 does not extend beyond the plane defined by the outer surface of the sleeve 16", so there is nothting to interfere with the cap attachment apparatus.

To open any of the above-described caps, the user will by force of habit hold the scissors with the blades directed away from him and will orient the container so that the spout lies generally perpendicular to the blades and is therefore directed to the side. When the closed ends are snipped off, any liquid or bubbles ejected from the container will be directed harmlessly away to the side.

When the liquid is to be dispensed, the user tilts the container, at the same time applying pressure to it, until the contents are ejected through the open spout, the spout, of course, being aimed in the direction of the vessel which is to receive the contents. Inasmuch as the spout is oriented generally laterally rather than parallel to the axis of the container, it need be only partially tilted in order for the liquid to be dispensed in a downward stream, unlike the presently known containers having axially aligned spouts from which the liquid often prematurely squirts out horizontally.

Thus, there is provided, in accordance with the invention a cap for a container for liquid having a spout which directs a stream of the liquid generally laterally with respect to the axis of the container and which is adapted to be opened when the spout is directed to the side with respect to the user, thereby preventing accidental ejection of the liquid into the users face or clothing when the user is opening it and preventing a premature ejection of the contents in a horizontal or upward stream when the container is being tilted to dispense the contents.

It will be understood by those skilled in the art that the embodiments of the invention described above are meant to be merely exemplary andare susceptible of considerable variation and modification without departing from the spirit and scope of the invention. For example, the spout may be directed either downwardy or upwardly with respect to the horizontal, and the claims, in referring to a spout directed laterally with respect to the vertical axis of the container, are intended to encompass this and other variations from the specific embodiments. Therefore, the scope of the invention will not be deemed limited except as defined in the appended claims.
