DISCHARGE SPOUT FOR masnmm WALLED DISPENSERS Filed Nov. 27. 1946 Patented Mar. 14, 1950 DISCHARGE SPOUT FOR BESILIEN'I WALLED DISPENSERS Herman B.

1 Claim. 222-215) The object of this invention is to provide a dispenser which may be made of transparent, plastic material, which is light in weight, is adapted to be accurately manually manipulated for the controlled discharge of the contents in small, measured quantities, and which is eflicient and durable in use. a

A further object of the invention is to provide a dispenser so constructed that it may be rapidly manufactured in large quantities by the use of suitable machinery.

A further object of the invention is to provide a dispenser of novel structural features such as will appear more particularly from the description hereinafter.

In the drawings,

Fig. 1 is a vertical, sectional view of a cap member adapted to be used in connection with the dispenser of my invention,

Fig. 2 is a vertical, sectional view of the spout.

member thereof,

Fig. 3 is a vertical, sectional view, partly fragmentary, showing the spout member afllxed to the body member of the dispenser,

Fig. 4 is an elevational view of a dispenser embodying my invention, with the cap aflixed thereto, and

Fig. 5 is a similar view, with the cap removed, showing the manner in which the dispenser may be manually compressed for the measured discharge of the contents thereof.

As shown in the drawings, the dispenser l0 embodying my invention comprises a body member which is preferably made of cellulose acetate or of a similar plastic material, light in weight, preferably transparent or translucent, and possessing a high degree of elasticity throughout its length.

The dispenser body comprises an elongated tubular member ll of thin-walled construction, which is highly flexible throughout its length and is maintained rigid at its opposite ends A, B. The member II is closed at one end l2, said closed end having a medially concave portion to define a rigid rim It to impart stiffness to said end II. The end I! of the body member H, may, instead of having the recessed portion l3 defining the rigid rim It, be thickened or otherwise deformed or fabricated for the purpose of making the same relatively rigid.

The spout II; of the dispenser is provided with a flared shoulder I! having a circumferentially recessed portion I8 adapted to register with and be fixed to the open upper end l5 of the member II, as by cementing the same thereto as at l9,

2 entswell knowntothoseskilledinthisart. The spout member I 6 may be made of the same mate- .rialasthe member ll ormaybemade ofamaor by the use of any of the other sealing expediterial having different characteristics, if desired. The spout member is preferably substantially rigid, being made of substantially thicker and less yielding cross-section than the tubular member ll, so as to rigi y hold the upper end of said tubular member thereto. The tubular body member II is thus rigidly held at opposite ends A and B thereof, while the thin-walled, elongated construction thereof throughout its length renders the same highly elastic and subject to ready compression manually, as hereinafter more fully explained.

The spout I6 is provided with a longitudinal medial aperture 2| which is tapered toward the end 2| of said spout remote from the shoulder I! so that, at the discharge end of said spout, the aperture will be of relatively small size. The spout 'is further provided with an externally threaded portion 22 adapted to be threadedly engaged by the internally threaded portion of the cap 23 to seal the dispenser. In addition, the spout I6 is provided with a non-circular flange 25 integrally extending therefrom but spaced from the closure II a suflicient distance to provide a ringer receiving and cooperating area, while there is a similar non-circular flange 26 on the cap 23 to provide a second finger cooperating area. By holding the flange 25 in the fingers of one hand and the flange 26 in the fingers of the other hand, the cap may be readily removed and replaced as needed, even though the outer surface may otherwise be too slippery to grip securely.

In manufacturing the device, the body member I I is initially filled with the product to be dispensed, and then the spout I6 is aiiixed thereto, as above described, closing the same. The cap 23 is threaded onto the spout, effectively sealing the same. The cap may be readily removed therefrom when it is desired to discharge the contents of the dispenser. At such time, the dispenser may be inverted as shown in Fig. 5, and the thin walls ll thereof manually compressed to discharge measured quantities of the contents. By virtue of the relatively small size of the aperture 2| at the end of spout It, the contents of the dispenser, such as, for example, oil. will normally tend to remain within the dispenser and will be ejected therefrom only in measured quantities responsive to the compression of the walls ll manually as indicated at 2!. By this arrangement, it is possible to direct the spout aperture to the precise point at which oil or other contents of the dis- E li ' mam preferably made of a transparent or translucent plasticmateriaLitispossible atalltimes toobserve the quantity of material within the dispenser, and the rate of discharge of material therefrom.

The cap 23- is preferably made of an opaque tobeapplled andtodischargethe material or of a material distinctly colored from 10 the material of the spout, so that the userxnay observe at a glance whether or not the cap is fixed to the dispenser. The spout l6, tubular cated of plastic material by use of any of the methods conventional in they plastic industry or suitable for the purpose.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

A dispenser for liquids comprising a tubular, resilient, cylindrical body member having a closed end and an open end, a hollow closure member for the open end of the body member, the said closure member having an annular shoulder at one end adapted to receive the open end of the body member and a discharge tip at the other end, the said shoulder having a hollow cylindrical apron depending therefrom, adapted to be remember I l and cap 23 may be molded or fabriceived in the open end of' the body member, the an apron having a substantially smooth outer wall adapted to flt snugly in the open end of the body 4 member, the closure member being secured to the body member, a spout for the closure member integral therewith, said spout being uniformly and continuously tapered from the shoulder 'to the discharge tip, a finger cooperating noncircular flange extending from the outer tapered surface of said spout adjacent to but sumciently spaced from the closure member shoulder to provide a finger receiving area, a uniformly tapered discharge passage in the spout extending therethrough, a threaded cylindrical sleeve on the spout portion located remotely from the tip, but between said linger cooperating flange and said tip, and a conical closure cap having an internally threaded, cylindrical open end adapted to threadedly engage the threaded cylindrical sleeve on the spout for enclosing the tip and a substantial length of the spout, and a non-circular flange integrally extending from the outer surface of the internally cylindrical open end of said cap to provide a second finger cooperating area.
