SANITARY CONTAINER CLOSURE WITH DISPENSER Filed Jan. 21, 1960 INVENTOR. 40'-\i 42 fPDSELY/V (SA/NOR 4 W M M ATTORNEYS- United States Patent 3,945,723 SANITARY CQNTAENER CLQSURE WITH DISPENSER Roselyn Gainer, 523 West End Ave, Haddonfield, NJ. Filed Jan. 21, 1960, Ser. No. 3,871 7 Claims. (Cl. 141-381) This invention relates to a container closure and to a dispenser such as a spoon for the contents of the container, and more particularly to a sanitary closure having an attached dispenser.

In the past, container closures have been provided with attached dispensing elements such as a spoon. However, this invention has as its main object the provision of a new and improved combined closure and dispensing element in which the dispensing element is readily available for use and at the same time does not contaminate the contents of the container.

Another object of this invention is to provide a new and improved combined closure and dispenser in which the dispenser is readily available for cleaning.

Another object of this invention is to provide a new and improved combined container, closure, and dispenser in which the dispenser as well as the contents of the container may be maintained in sanitary condition.

Another object of this invention is to provide a new and improved combined closure and dispenser in which the dispenser may be cleaned without disturbing the contents of the container and may thereafter be maintained in sanitary condition.

Another object of this invention is to provide a new and improved combined closure and dispenser in Which access may be had to either the container contents or to the dispenser without disturbing the other.

In accordance with this invention .a container is provided with a dispensing cover that includes a cap and a dispensing element attached thereto. The cap includes means for attachment to the container to provide a sanitary closure therefor. The dispenser is attached to and projects externally from the cap. A transparent cylindrical shield, closed at one end, engages the cap at the other end with the dispenser contained therewithin. The cap includes means for engaging the open end of said shield to provide a sanitary seal for the protection of the dispenser. Thereby, a sanitary seal for protecting both the container contents and the dispenser is provided. Access to either without disturbing the other is made available, so that the dispenser may be cleaned while the container is kept closed and the container opened without affecting the dispenser.

The foregoing and other objects and features of this invention as well as the invention itself both as to its organization and mode of use may be best appreciated from the following description when read together with the accompanying drawing in which:

FIG. 1 is a view in perspective of a closure and dispenser embodying this invention;

FIG. 2 is a sectional view in elevation along the line 22 of FIG. 1;

FIG. 3 is an exploded view in perspective of the dispenser and container of FIG. 1 in position for use; and

FIG. 4 is an elevational View partly in section of another embodiment of this invention.

In the drawing, corresponding parts are referenced by similar reference numerals. In the embodiment of FIG- URES 1-3, a glass bottle or jar is shown of the type having a screw threaded mouth 12 to which a closure 14 may be removably secured.

The closure 14 includes a cap portion 16 which, by way of illustrating, is metal and screw threaded for attachment to the threaded mouth 12 of the bottle 10. The cap 16 has secured to its center and projecting ex- 3,45,7Z3 Patented July 24, 1962 ice ternally therefrom a spoon 18, which is also metal by way of illustration. The shank of the spoon 18 is rectangular in cross-section and is embedded in a slot of similar shape formed in the center of the cap. The spoon 18 is suitably bonded to the cap. The spoon 18 and cap 16 may be cast in an integral construction where appropriate. A gasket 21 fitted within the cap 16 insures a suitable seal for the bottle 10.

The closure 14 also includes a shield 22, which is cylindrical in shape having closed upper end 24- and an open lower end.

This shield 22 is preferably made of transparent material such as, for example, a moldable plastic.

Secured to the outside rim of the metal cap portion 16 is a plastic collar 26 that has knurling 28 formed on its outer surface. The collar 26 has an annular shoulder 30 integrally formed around its lower edge and extending inwardly. The shoulder 30 rests on an annular lip 32 formed around the lower edge of the cap 16, and shoulder 30 is firmly bonded to the metai cap portion 32 so that the collar is part of the cap. Thereby, the collar 26 may be readily grasped to unscrew and to tighten the cap 16. The collar 26 is preferably fabricated of a yieldable material such as a soft nioldable plastic so that a tight fit may be made between the outer surface of the shield 22 and the inner surface of the collar 26.

In use, access to the spoon 18 without disturbing the contents of the bottle may be had by elevating the shield 22 in the direction of the arrow 34 to the position indicated by the prime numerals 22, 24'. The spoon is then uncovered and available for cleaning or for use as a dispenser. The cap 16 may be left tightly secured to the bottle 10 at that time even though the spoon 18 is fully accessible.

After the spoon is cleaned, the shield 22 may be returned to covering position securely positioned in contact with the collar 26 to provide a tight seal. The external surfaces of the cap 16 are completely enclosed by the shield 22 and collar 26 so that the spoon 1 8 is completely protected against contamination. The shield 22 being transparent, the condition of the spoon 18 may be readily viewed. The transparent character of the shield may be used to advantage in packaging and for display purposes.

For dispensing the contents of the bottle 10, for example, a dose of medicine therefrom, the collar 26 may be manipulated to remove the cap 16. The removal of the cap 16 may be performed without removal of the shield 22 and without affecting the spoon 18. Thus, if the user desires, he may use another spoon and leave the spoon 18 in clean condition. Such use may be possible, for example, if the use were at home where other spoons were readily available.

However, where the user is away from home, he can also remove the shield 22 and dispense the contents of the bottle 10 with the spoon 18. After dispensing a dose of medicine in this way, the cap 16 may be restored to position closing the mouth 12 of the bottle. The spoon 18 may then be washed if facilities therefor are available, and the shield returned to its protecting position.

However, if washing facilities are not available, the spoon 18 may still be protected for certain purposes by the shield 22 being restored to position sealing the spoon from external contamination. Thus, the same user may, under many circumstances, reuse the spoon 18 even though cleaning facilities should not be available in the interim period and without fear of contamination. When such cleaning facilities are again available, the shield 22 may be removed, the spoon 18 cleaned, and the shield restored, all without any adverse effect on the contents of the bottle 10, which remains tightly capped. The spoon 18 may be used repeatedly in this manner. This invention may be used with dispensing elements other than a spoon and may be used for containers other than those for medicines. For example, prepared baby food containers may be supplied with a spoon or fork on the cap and used in the manner described. Other dispensing elements such as a reusable applicator which are liable to contamination in use may be stored outside of the container itself in this way.

Another embodiment of this invention is illustrated in FIG. 4. A plastic unit as shown in FIG. 4 includes a cylindrical cap 40 which may have threads 42 therein and a spoon 44 formed externally. The shank of the spoon 44 is attached to the cap 40 and extends up from the top of the cap 40. The unit of cap 40 and spoon 44 may be molded integrally from a suitable plastic material. A cylindrical shield 46 with a closed top end 48 and preferably transparent may also be molded from a suitable plastic. The internal diameter of the shield 46 at its open end is substantially the same as the external diameter of the upper portion of the cap 40 to ensure a tight sealing fit. The upper portion of cap 40 should be smooth for this purpose, and knurling similar to that on the collar 28 may be provided around the lower outside surface of cap 40 to provide easy manipulation. Alternatively, the cap 40 may be molded with a recess at its upper rim to receive the shield 46 and to provide an internal surface for engaging the open end of the shield in a manner similar to that of the collar 26.

In use, the embodiment of FIG. 4 may be handled similarly as described above for the embodiment of FIG. 1. Such use will be apparent from the foregoin description. It has been noted that the shield 46 makes direct contact with the cap 40 to provide the desired seal.

The use of plastic for the cap offers the advantage of providing a simple and inexpensive construction. The flat surface of the top of the cap 40 and the projection of the shank of the spoon 44 are easy to keep clean since they are readily accessible. Likewise, these spoon and shield elements 44 and 46 may be appropriately dimensioned to provide a compact construction. Various shapes of the shield and spoon together with suitable dimensions afford the basis for an attractive and convenient package both for the user and for a manufacturer or merchant.

The embodiment of FIG. 4 lends itself for use with various types of cap constructions other than the threaded cap construction described above. Thus, this invention may also be used with the conventional beaded rim bottle mouth, and the cap may be provided with a suitable form of snap fastener for tightly gripping the beaded rim of the bottle. Such variations of the form of this invention will be readily apparent to those skilled in the art. It is not intended to limit the invention to any particular form though a preferred form thereof has been disclosed. Various modifications of features of this invention will be apparent to those skilled in the art and are intended to fall within the scope of the appended claims.

Thus, it is seen from the foregoing description that a new and improved combined closure and dispenser for a container is provided. The contents of the container or the dispenser may be made accessible without disturbance of the other or, alternatively, both may be used. A sanitary arrangement for the container and the dispenser is ensured.

In addition, the size of spoon 18 can be varied for large or small dosage. For example, spoon 18 may be large enough to dispense at one time a tablespoon or more of liquid as may be required in connection with the dosage of mineral oil.

Moreover, shield 22 may have marked thereon a graduated scale 23 whereby shield 22 may serve as a measuring member for a given volume of liquid in the event that an accurate amount of liquid is to be dispensed.

Furthermore, a depression 17 is provided on cap portion 16 at the base of the shank of spoon 18 to collect any liquid which remains in spoon 18 after dispensing. Such liquid would ordinarily run down to the base of the shank of spoon 18 and thence upon cap portion 16 to shield 22 to produce unsanitary fouling of the dispensing device. Depression 17 functions to minimize such fouling.

Obviously many modifications and variations of the present invention are possible in the light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
