ROBERT N/DEA United States Patent O 3,192,555 CONTAHIER DISPENSER CAP WETH CAPTIWE CLGSURE MEMBER AND APPLICATOR Robert Nyden, Manhasset, N.Y., assignor to Pittsburgh Plastics Division Heelrin Can Co. Filed June 19, 1963, Ser. No. 289,123 6 Claims. (Cl. 592) The present invention relates to improvements in dispenser caps for fluid containers, and in particular to a novel and improved closure and dispenser cap having applicator means for spreading the fluid content dispensed by said cap.
In dispenser caps for fluids or semi-fluids, such as glue or the like, it is customary to provide the cap itself with a closure member to cover up the outlet opening. It is also known to provide the closure member with an upstanding applicator portion or extension for spreading the fluid dispensed along a surface. The dispenser cap closures are small and tend to become lost or misplaced, resulting also in the loss of the applicator.
Captive closure members for dispenser caps are also known, these closure members being joined to the cap itself by an integral flexible strap. Such captive clo sure members are not provided with applicator means and are not adapted to carry such means because of the requirement that the applicator means be mounted at the top of the closure member, which is the point at which finger pressure must be applied to press the closure member onto the dispenser cap.
It is the principal object of the present invention to provide a closure cap for fluid containers which includes a captive closure member and also a fluid applicator, both carried by an integral strap.
Another object'of the invention is to provide a closure cap of the character described in which the applicator is located to spread the fluid dispensed, while the closure member is either inserted in said cap in a closed position or is removed from said cap in an open position.
In accordance with the invention herein, there is provided a plastic dispenser cap having means for attachment to a container in communication with the mouth thereof and having an outlet opening for dispensing fluid from the container. The dispenser cap has an integral flexible strap which carries a closure pin spaced a short distance from the end of said strap. The closure pin is adapted to be snap-fitted within the outlet opening of the dispenser cap to close off the latterto the passage of fluid. The strap has an end portion projecting beyond said pin,'the outer edge of this end portion being formed with a row of teeth serving as an applicator for spreading over a surface the-fluid dispensed from said container.
Additional objects and advantages of the invention will become apparent during the course of the following specification when taken in connection with the accompanying drawings, in which:
FIG. 1 is a side elevational view of a dispenser cap made in accordance with the invention and shown mount ed on the neck of a bottle, the closure member of said cap being shown in closed position in full line and in open position in broken line;
1 16. 2 is a front elevational view of the dispenser cap shown in FIG. 1;
.FIG. 3 is a top plan view thereof, with a portion of the flexible strap broken away;
FIG. 4 is a vertical section through the dispenser cap, taken substantially along line 44 of FIG. 2;
FIG. 5 is a partial section similar to FIG. 4, showing the outlet opening of the dispenser cap with the closure pin therein, on an enlarged scale; and
FIG. 6 is an elevational view showing the applicator "ice portion of the inverted dispenser cap in use for spreading fluid.
Referring in detail to the drawings, there is shown a container 10 with a dispenser cap 18, made according to the invention, mounted thereon. The container 10 may be made of a flexible and resilient plastic with a hollow body 12, and a neck 14 formed with external threading 16. The container 10 may contain a liquid or a viscous fluid such as glue, and because of the flexibility of the body 12, the glue may be fed through the mouth of the inverted container by squeezing the walls of said body.
The dispenser cap 18 includes an annular skirt 20 hav-' ing a top wall 22 supporting at its center an upstanding conical nozzle 24. The nozzle 24 has a top wall 26, which, as shown most clearly in FIG. 5, is provided with a central outlet opening 28. The outlet opening 28 is of a smaller diameterthan the top wall 26, so as to provide a marginal shoulder 36 surrounding the bottom end of said outlet opening 28.
The inner surface of the skirt 20 is formed with threading 32 which meshes with the threading 16 on the bottle neck 14 to mount the dispenser cap 13 on the bottle 10. In this mounted position, the interior of nozzle 24 communicates with the interior of the bottle through a oentral aperture 34 in the top wallZZ.
The dispenser cap 18 is molded of a flexible or semiflexible plastic such aspolyethylene, and when the skirt 2% is turned fully down on the neck threading 16, the inner surface of upper wall 22 engages the edge of the bottle mouth, as shown in FlGf4, to provide a tight seal about said mouth.
The dispenser cap 18 is formed integrally with closure means 36 which includes a flexible strap 38 projecting as an integral extension from one side of the periphery of the top wall 22. A closure pin or plug itl is formed integrally with the strap 36 and projects perpendicularly therefrom at a point spaced slightly inwardly from the free end of said strap. As shown in FIG. 5, the closure pin 40 has a cylindrical body portion terminating in an annular flange or snap bead 42 and having a tapered extension 44 projecting beyond said bead.
In closing the dispenser cap, the extension 44 is first fitted into the outlet opening 28 of nozzle 24, the tapered shape of said extension permitting it to be accurately guided into said outlet opening. The users finger is then placed against the strap 38 above the pin 40 and downward pressure is exerted thereon. This causes bead 42, which is of greater diameter than the outlet opening 28, to be forced through said outlet opening until it has passed entirely therethrough and the cylindrical body portion of pin 4%) is within the opening 28. 'Said cylindrical body portion is of slightly larger diameter than opening 28 so that it closes off said outlet opening and provides an airtight and liquid-tight seal therefor. The insertion of the pin 40 within the outlet opening 28 is therefore a snap action, and in the inserted position shown in FIGS. 4 and 5, the bead 42 is located beneath opening 23 and will abut shoulder 30 to prevent accidental withdrawal of the pin 4% A projecting annular flange 46 is molded into the outer surface of strap 33 immediately above the pin 40 in sucha position that it surrounds the base of pin 40 and is concentric therewith. This flange 46 provides rigidity for the strap 38 in the vicinity of pin 46 to prevent buckling of the strap when the aforementioned finger pressure is applied thereto and when the pin is to be removed by upward pulling pressure on the end of strap 38. The flange 46 also serves as a visual guide for the proper placement of the finger when the downward pressure is to be applied upon the strap.
The end portion of the strap immediately surrounding the pin 49 is made of somewhat greater width, as indicated at 50 in FIG. 3. The end edge of this wider portion 50 is provided with a continuous row of teeth or serrations 52 which'serve as applicator means for spreading fluid dispensed from the container 10. In dispensing the fluid, such as glue or the like, the pin 40 is removed from the outlet opening 28 and the strap 38 is allowed to swing back to the clearance position shown in broken line in FIGS. 1 and 4. The walls of the compressible container It are then squeezed together, forcing the contained fluid F through the outlet opening 28 on to a surface S. The pin may then be reinserted and firmly locked within the outlet opening 28, are previously described, thereby providing a rigid mount for the applicator teeth 52. The container 10 is then inverted and held at an angle, as shown in FIG. 6, with the hand, grasping the container body 12 as a handle, and the applicator teeth 52 -are pressed upon and drawn along the surface S to spread the fluid F thereon. Because of the resilience of the strap 33, the teeth 52 can be pressed tightly against the surface S during the spreading action to provide a thin, uniform layer-of the fluid F on the surface. If desired, the applicator may be utilized in the same manner with the pin 4% removed from the outlet opening 23. In this open position, shown in broken line in FIG. 1, the container 10 is inverted and the teeth 52 wiped along the surface S, the flexible strap 38 providing a more resilient spreading action.
It will be appreciated that because the closure pin it? and the applicator teeth 52 are both carried by the integral strap 38, these members are always available when needed and cannot be lost, dropped or accidentally misplaced.
While a preferred embodiment of the invention has been shown and described herein, it is obvious that numerous omissions, changes and additions may be made in such embodiment without departing from the spirit and scope of the invention.
