SEALABLE CONTAINER cLosURE Filed Aug. 10, 1960 6 INVENTOR MAX FRIEDMAN ATTORNEY United States Patent O lice 3,044,651 Patented July 17, 1962 3,044,651 SEALABLE CON'EAENER CLQSURE Max Friedman, 122 S. Main St., High Point, N. Filed Ang. lil, 196i), Ser. No. 43,674 Claims. (Cl. 21S-31) This invention relates to closures and more particularly to a closure for a container for liquid or granular substances which must be sealed from the air during storage and which permits variable discharge yand is not removable in ordinary use from the container.
In the operation of various lfacilities, particularly in the home, it is customary to keep on handy for occasional use various products such as hair Itonic, shaving lotion, shampoo, detergents, ffood seasoning, rubbing alcohol yand lthe like, resulting oftentimes in the storage of containers of such items for lengthy periods of time. As a result, such products frequently become altered because of exposure to the air, including loss of alcohol contents, resulting in unfitness for use and wastage of the contents of the container. Another problem` in humid areas is the absorption of .moisture in condiments unless the same are sealed when not in use.
Heretofore, various closures for containers have been provided, but these have suffered from various deficiencies, including trapping of excess material in the closure during dispensing, such material becoming lost when the container is closed or causing clogging or other malfunction of the dispenser.
Other closures have not provided an adequate seal or have been too complicated or expensive for use on relatively low cost products.
Accordingly, it is an object of .the present invention to provide a variable flow scalable container closure which is characterized by a direct ow path `from the container to the outlet, the same being so constructed and arranged that a minimum of material is trapped within the cap when the same is closed.
A further object of the invention is the provision of a variable flow scalable container closure which is not removable in ordinary use and which is relatively simple and inexpensive to produce.
These and other objects of the invention will become apparent from the following description in conjunction with `the accompanying drawing, in which:
FIG. l is an elongated section through the neck and cover of a closure constructed in accordance with the present invention, illustrating the same in the closed position;
PEG. 2, a section similar to FIG. 1, illustrating the open position;
FIG. 3, la top plan View;
FIG. 4, asection on the line 4-4 of FIG. 2;
FIG. 5, a section partly in elevation, to a reduced scale, of a modified form of the invention;
FIG. 6, a top plan view, to a reduced scale, of a further modiied for-m of the invention, and
FIG. 7, a plan view, to a reduced scale of the split retaining ring of FIG. 5.
Briefly stated, the present invention is embodied in `an inter-engaging cap and a neck or neck-like portion of a container. The threaded container element has an enlarged curved extremity and `a reduced tapered portion adjacent thereto through which the container bore extends. The cap has a cylindrical threaded portion with a flexible `seal which 4engages the tapered portion of the neck and has an apertured `dome-like end with a depressed central area having a `seal which is received in the bore to close the container. Due to the depression of the dome-like portion of the cap and the location of the apertures in the peak portionof the dome, when the cap is open the vcontents has -a direct flow path through the apertures, resulting in smoother discharge and minimizing the trapping of material in the cap when the latter is closed. 5 Referring to the drawing, a container is illustrated having a neck with an inner bore 11. The container may be of the type used `for liquids of various types or for condiments, such as salt and pepper shakers. If of the rciillable type a conventionally stoppered opening (not shown) is conventionally provided in the base. The neck is provided on its exterior with threads 12 below which -a frange lI3 protrudes, the same tapering outwardly in a direction away from the threads andy providing a ledge or abutment 15 on its under side.
The container has a dome-like extremity 16 which is preferably of slightly less diameter than the main portion of the neck. Intermediate the main portion of the neck and the dome-like extremity 16 is a tapered p0rtion 17 of reduced diameter, the same tapering from a larger to a smaller diameter towards the dome-like portion i6. The bore 17 within the reduced portion of the neck is preferably smaller than the bore 11 within the main portion thereof. At the outer extremity of bore 17' the junction with the outer surface of dome i6 is preferably rounded as indicated at 18 in order to provide `a smoother surface for engagement with a exible seal member 19 mounted in the end of cap 20.
rEhe cap 20 has an outer substantially cylindrical Wall 2l connected to a dome-like extremity 22 by a flange portion 23. The dome-like extremity 22 has a plurality of apertures 24, of any desired size or shape in its peak portion, the central portion 25 of the cap being depressed within the peak for reception in the other end of bore 17 in order that the ring-like sealing member 19 attached to its under side may seal the end of such bore.
The inclined sides of the depressed portion are preferably raised to provide an annular cavity or space 26 for the sealing member in order that the exposed surface may be iiush with the adjacent portions of the cap, thereby providing a smooth uninterrupted ow path for the material when it is discharged.
Pilie cap is rotatably mounted on the neck of the container by an inner wall port-ion 30 having threads 31 for engaging the mating threads 12 of the neck. The lower portion of the inner wall 30 has la ilange 32 which engages ilange 21 of #the outer wall, the same being crimped together by an annulus 3S. The annulus 35 has an inner lip 36 which extends inwardly of the inner wall 30 and has a minimum diameter just sul'licient to pass over the flange 13 on the bottle neck. The inner edge of the lip 36 is distorted in a plurality of locations to provide inwardly projecting `dimples 38 Whose surfaces ride over the curved portion of the flange 13 on the bottle neck as the cap is assembled thereon but catch beneath the ledge 15 of the flange to prevent removal of the cap after assembly.
The upper end of the inner wall 30 has a ange 40 with projections 41 extending upwardly for engaging a flexible ring-like sealing member 44 which is mounted with its `outer rim between the flange and the flange portion 23 of the cap. In order to cooperate with the flange 40 in holding the sealing member 44, the flange portion 23 yhas a raised portion 46 providing a concavity beneath the iiange portion 23, land the junction 4S between such flange and the outer rim of dome 22 is depressed downwardly below the upper extremity of the outer wall 2i. Sealing member 44 has an inner diameter smaller than the maximum diameter of the containers tapered portion 17 and preferably slightly 70 smaller than its minimum diameter. As a result of initially positioning the sealing member Within the cap prior to assembly on the container, the inner portion of the sealing member will be curved downwardly as indicated in FIG. 2. When the cap is assembled onto the neck the opening in the seal 44 is stretched to pass over the dome 16, the concavity within the raised portion 46 of the flange accommodating some of the stretched portion of the seal.
In the operation of the device the cap is moved from the closed position of FIG. l to the fully open position of FIG. 2 by unscrewing the sarne along the neck. This unseats the seal i9, providing a space between it and the bore 17 through which material may llow to the apertures 24. The cap may be unscrewed a variable amount in order to vary the iiow. As a result of the apertures being located in the peak of the domelike extremity, material is urged by gravity to llow through the apertures when the container is inverted, thus avoiding trapping of such `material when the container is closed, and the direct flow path from the bore 17 through the apertures 24 facilitating the discharge through the apertures 'of any material that passes out of the end of bore 17. As a result, a minimum of material is trapped beneath the cap when the same is closed.
In the modification of FIG. the cap has been simpliiied by the elimination of the lower lip which provides a positive stop against removal of the cap. However, :in such modiication the sealing member 44 engages the under side of the dome portion 16 of the container, thus indicating to the user that the cap has been opened a normal amount in order to avoid inadvertent removal of the cap.
Although such indication alone may be satisfactory for certain uses, `a positive stop is provided in the modication. The stop is a relatively thin split retaining ring having an inner portion 51 for positive engagement beneath the dome portion and an upturned lip 52 for engagement between the sealing member 44 and the cap. The ring enlarges when the dome is inserted during assembly but snaps back to its initial diameter after assembly, as indicated in FIG. 5, in `which it closely engages the upper end of the portion 17 of the neck of the container and engages the underside of the dome when removal of the cap is attempted.
In the modification illustrated in FIG. 6, the domelike extremity 22 has a series of elongated arcuate slots 55 to discharge the contents therefrom more rapidly.
Accordingly, it will be understood that the invention includes a closure for a threaded neck-like portion of a container, such portion having -a dome-like extremity with lan intermediate tapered portion of reduced diameter adjacent thereto, a flange at its lower portion, and a cap threaded for engagement therewith having in one form a lip for engaging the ange on the neck and having a centrally depressed domelike extremity with discharge apertures in the peak portion and a seal therebeneath for reception within the end of the container for sealing the same, the cap having a second sealing member intermediate its extremities for engaging the reduced portion of the neck member.
It will be obvious to one skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof and t ereiore the invention is not limited by that which is illustrated in the drawing and described in the specifica-tion, but only as indicated in the accompanying claims.
