United States Patent COMBINATION DISPENSER AND SEAL Earl S. Tupper, Upton, Mass.

Application July 28, 1953, Serial No. 370,738

9 Claims. (Cl. 222-189) This invention relates generally to a spice and condiment dispenser having both a removable distributor element and a hinged and swivellable seal therefor to maintain a non-spillable relationship with the distributor element when the dispenser is not in use.

The assembly and parts herein utilizes the structure described and claimed in U. S. Patent No. 2,487,400, granted to the applicant herein on November 8, 1949, and further utilizes the structure described in applicants appligastion for Patent Ser. No. 327,958, filed December Essentially, the seal assembly to maintain the vessel contents air and vapor tight comprises a closure member formed of polyethylene or other plastic having similar physical characteristics and is hingedly and swivellably secured to a neck formed on the condiment receiving vessel such as a bottle, or to a neck formed on a wall of other type of container. The neck is preferably, but exclusively, also made of polyethylene or other plastic having similar characteristics to enable a live seal to take place between the closure member and the lip of the neck.

At the base of the neck, the invention contemplates the application of a removable and snap-type of distributor or strainer element having a perforated upper wall which is adapted to seal-tightly engage a depressed wall portion of the closure member when the closure is closed whereby the spice or other condiment within the container is prevented from spilling during movement or transportation of the device.

Another object of the invention resides in the utilization of a material in conjunction with specified structure such as polyethylene or other plastic having similar characteristics comprising a rubber-like thermal plastic composition which does not absorb and is not readily wetted by water, is odorless, resistant to acids, solvents and other chemicals, will not soften in ordinary temperatures, is unbreakable, has flexibility and elasticity with a slow rate of recovery, is frictional to the touch, is light in weight, is unaffected at working temperatures and affords a sterile medium for and consequently is resistant to mildews, micro-organisms and insects.

Another feature of the invention resides in the provision of a non-spillable condiment vessel having a closure member hingedly supported on a swivellable frame member disposed on the neck of the vessel, the said closure member having its lower or depressed wall in contact with a removable strainer or distributor element in the neck of the vessel when the said closure member is in sealing position, the said closure, frame and strainer members all being capable of being molded by compression or injection in all their parts, and which are economical to manufacture, durable, easy to clean, and efficient in operation.

A further feature of the invention resides in the convertibility of a condiment cellar or distributor to a pouring vessel provided with a seal.

These objects and other incidental ends and advantages will hereinafter appear in the progress of the disclosure and as pointed out in the appended claims.

Accompanying this specification is a drawing showing a form of the invention wherein:

Figure 1 is a view in perspective of the hinged closure member mounted on a frame swivellably engaged to a spout or neck on the wall of a flat cover member for the "ice showing dispensing or distribution of the condiment material.

Figure 3 is an enlarged sectional view of Figure 1 across the plane 33 thereof showing the plane contact between the lower or depressed bottom wall of the closure member and the upper surface of the straining element to prevent spilling.

Figure 4 is a sectional view of the upper portion of Figure 3 showing the strainer or distributing element in a lower and displaced position from the spout of the cover of the vessel.

In accordance with a form of the invention shown, numeral 10 indicates a vessel, which may be of any type, having a top closure wall 11, and a spout generally indicated by numeral 12. Vessel or container 10 may be used for any purpose but with the provision of a pouring neck or spout may readily be converted into condiment holder by the application of a removable snap-in type of sltraining element insert generally indicated by numeral The neck or spout 12 forms an opening for the container or vessel, but as shown is formed on Wall 11 forming part of a removable cover member generally indicated by letter A. Cover A is comprised, as has been mentioned, of a main central wall already designated by numeral 11, and has an upwardly extending peripheral rim generally indicated 12a, said rim being formed as an inverted groove and having an inner- Wall 13, a spaced outer wall 14, a top connecting wall 15 and a portion 16 offset from the base of the outer wall 14, the rim 12a being adapted to sealably engage the upper edge of the container 10. Cover A is preferably made of polyethylene or other substance having similar physical characteristics, but for purposes of the invention herein is not so limited.

Spout 12 may form the top terminal of a container such as a bottle or other vessel, but as shown forms a neck surrounding an opening 17 in Wall 11 of cover A. The spout as shown is provided with an intermediate shoulder 18 extending at the top from an outwardly inclined wall 19 at the inner side of the base of the spout.

The strainer element 13a is in the form of a cap having a top wall 13b provided with perforations 13c and a pcripheral side wall 13d terminating in a peripheral outwardly directed flange 13e. Flange 13s is adapted to snap in and out of shoulder 18 as best seen in Figures 3 and 4 and makes a snug fit therein by virtue of the inclination of the spout lower inner wall 19. Shoulder 18 at the horizontal portion acts as an upper stop for flange 13e while inclined wall portion 19 serves as a frictional stop against normal downward travel.

The closure for the spout 12 consists of a depressed lower Wall 20 having a peripheral and upwardly extend ing inverted grooved rim formed of an inner wall 21, an outer wall 22, a top connecting wall 23, and an outwardly extending flange 24 continuing from the lower edge of outer wall 22. Flange 24 at opposite diametric points has a finger-operable tab projection 25 and an extension 26 provided with a platform 27 respectively. The said platform at its rear edge carries a cylindrical rod 28 which projects beyond each of the side edges thereof and the diameter extends above the platform 27 as best shown in Fig. 3.

It is to be noted that sealing by the closure member described is effected at the upper portion of the inside of outer wall 22 and the inside of top wall 23 with respect to the upper terminal wall 28a of spout 12 (outwardly inclined from shoulder 18 as shown). diameter of spout wall 28a therealong is greater than the inner diameter of Wall 22 whereby positive sealing engagement is assured between the closure member and the spout. When the spout wall 28a is made of poly ethylene or of a substance having similar physical characteristics as the closure member, a live seal is effectuated between the respective parts.

In order to provide the closure member with hinge and swivellable characteristics relative to spout 12, there The outer along the rear edge-thereofapair ofaligned lugs each indicated by numeral 31, said lugs having aligned cylindricalopenings eachindicated by numeral 32 and with a diameter sufficient to permit rod 28 to slide therethrough. Each of the cylindrical openings, 32 communicates with a top lug notch 33, each of said notches being substantially of width to'permit apron 27, to slide therethrough.

As shown in Figure 3, disc .or frame 29, which is.made of anysuitable, material butpreferably resilient plastic such as polyethylene or vinyl for accommodating differences in. spout diameters, is applicable over the .upper portion of spout wall 28a and is based. on the upper horizontal portion of shoulder 18 thereof for swivellable engagement therewith. Frame 29 is further capable. of removability when desired from the spout wall 2811 by anflupward pull necessaryto compress the said spout wa As best shown in Fig. 2, rod 28 ,is removably insertable by lateral linear motion into the aligned openings 32 of lugs 31 while notches 33 permit clearance for linear movement of apron 27 therethrough. Lugs 31 permit the closuremember .at rodZS .to be hinged for 180 degree rotary movement adjacent to the lip of the spout wall 228a foropening and closing purposes. The type of .hinging described also permits full withdrawal of the closure member: from'frame 29 and further permits the closure member at-wa'll portion 20,to lie flat on strainer wall 1312 thereby :to prevent spillage as will hereinafter appear.

-Although frame 29 withv the closure member mounted thereon is capable of beingswivellable while the closure member is in open position, nevertheless swivelling may be accomplished with the closure member in closed position.

As shown in, Figure 31,- it is to -beobserved that the width of 'apron 27tis less than the distance between the opposing; inner walls of lugs 31 to; permit rotation of rod 28 within the cylindrical openings 32 for approximately 180 degrees as has been mentioned.

I-n applying'thestrainer cap 13a to the spout walls, it is to be observed that cover member A of the Vessel is first; removed and thestrainer cap is snapped into positionbetween-shoulder 18 andthe inner side of spout wall 28a by being forced through opening 17. In this operatiomsince the diameter of opening fl is less than the diameter of flange 13e, finger pressure'isnecessary. Similarly for removable purposes, the closure member A must be first removed from vessel 10 to snapthe strainer out'by downward pressure against the spout wall 19.

It is to be observedbyzreferring to .-Figure 3 that'the strainer member 13a when in place presents a flat surface which is sealable by, depressed central wall 20 of the closure member.

To open the closure member theunder side of finger tab '25 mayibegrasped by thethumb while the index finger bears against the central wallZt). In this way,-the seal between spout wall 28a and the engagingwalls of the grooved rim of the closure'is'gradually and successively brokenin a pealing oif manner and at the same time the top wall 130 of the strainer element becomes exposed for distribution of condiment material 34. When there is full disengagement, the closure member remains hingedly, rotatably and removablysecured relative to spout 12.

For removal of the-.closure-member relative to frame 29, the closuremember is setat a-90 degree angle with respect to the horizontal plane and by lateral linear movement rod 28 is slidout of lugs 31. For-sealing purposes, the closure vmember is moved towards closed position on rod '28 mounted inlugs 31, and the operation is most suitablycompleted by continuous sliding finger pressure along the top wall 23 fromthe rear forwardly.

Thushas-been described -a sealing assembly provided with a removable strainer wherein the vessel on which the assembly cooperates may be converted from a container for pouringliquidstoa container for holding and for dispensing condiments oranything else in granular or powdered form. The closure for the strainer prevents spilling of the condiment contents between the wall 20 and the perforated wall-13b when the cellar is in inoperative position.

I wish it understood that minor changes and variations in the integration, size, shape,-material-and-location of parts may all be resorted to -.without departing from the spirit of the invention and the scope of the appended claims.
