Application December 26, 1952, Serial No. 327,958

Claims. (Cl. 210-1635) This invention relates generally to hinged and swivellable seal and strainer assemblies adapted to be removably secured to necks of bottles or vessels and for spouts on containers.

The assembly in parts utilizes the structure described and claimed in U. 5. Patent Number 2,487,400 granted to the applicant herein on November 8, 1949.

Essentially, the hinged and swivellable seal and strainer assembly comprises a plurality of similar closure members, the differences therebetween being in the condition of the central walls; namely, the central wall of the strainer closure member is perforated while the central wall of the sealing closure member is not. Each of the closure members are formed of polyethylene or other plastic having similar physical characteristics and is hingedly and swivellably secured to a neck formed on a vessel such as a bottle, or to a neck formed on a wall of the vessel. The neck is preferably, but not exclusively, also made of polyor other plastic having similar characteristics to enable a live seal to take place between one of the closure members and the lip of the neck.

Accordingly, the main object of the invention resides in the provision of a pair or plurality of similar closure members each hingedly and swivellably operable on the neck or spout of a vessel.

The closure member forming the seal is capable of serving as a closure for any useful type of vessel such as a beverage shaker, a dispensing device, a drinking cup, a salt and condiment cellar, a tumbler, a baby bottle, a canister, a food holder, a fluid package and the like; and the closure member forming a strainer or sieve is capable of serving as an ice-guard, sieve or strainer for the vessels above mentioned.

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 and waxy 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 plurality of similar closure members disposed on the same or contacting frame or mounting members disposed on the neck of a vessel or equivalent thereof, the said closures and frame members being capable of being molded by compression or injection in all their parts and which are economical to manufacture, durable, easy to clean, and efl'lcient in operation.

A further feature of the invention generally resides in the provision of a pair of hinged and swivellable similar closure members wherein the frame members thereof are in engagement with each other on the neck of the vessel for rotary motion to serve as displacement means for either the seal or strainer closure member when one or the other is required to be used.

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

Accompanying this specification are drawings showing forms of the invention wherein:

Figure 7 is a partial view in perspective of a modified form of mounting for a plurality of similar closure members adapted for alternate use and for hinged connection.

Figure 8 is an enlarged sectional view of Figure 7 across the plane 8-8 thereof.

Figure 9 is a view in perspective of a pair of similar closure members applied to the neck of a salt cellar,

said members being hingedly and swivellably secured vessel which may be of any type having a top closure wall 11 and a spout 12. Vessel or container 10 may be used for household, commercial or any other purposes wherein a pouring neck is required and wherein the neck is capable of receiving a pair or more of similar .closure members, one serving as a seal when required and the other serving as a strainer or sieve (as for salt cellars and the like) the said closure members each being removably and hingedly secured to swivellable, contacting and aligned frame members as will hereinafter be described.

The neck or spout 12 forms the top opening or pourer of a vessel and as shown in Figures 1-6, the spout is formed on a removable cover member generally indicated by letter A. Cover A is comprised of a main central wall already designated by numeral 11 and has an upwardly extending peripheral rim generally indicated by numeral 12a, said rim being formed as an inverted groove 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 engage the upper edge of container 10, the said edge as shown being expanded in the form of a bead 17. Cover A is preferably made of polyethylene or other substance having similar characteristics, but for purposes of the invention is not so limited.

Spout or neck 12 may form the top terminal of a bottle or vessel but as shown forms the spout surrounding an opening 18 in wall 11 of cover A and as shown is provided with an intermediate. shoulder 19 from which the outer surface of the spout may taper outwardly as shown in. Figures. 4 and 5.

In. one form of the invention, it is in connection with the vessel and bottle neck or spout 12, whether the walls thereof are inclined or not, that the similar closure members herein are. applicable.

Thus, the sealing closure member consists of a central wall 20 having a peripheral and upwardly extending 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 removal tab projectionv 25 and an extension 26 carrying a raised bracket platform 27. The said. platformv at its rear free edge carries a cylindrical rod 28 which projects beyond each of the side edges thereof and the diameter extends above and below said platform 27 as best shown in Figure 6.

It is to be notedthat thesealing 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 walls of spout 12, and that the outer diameter of spout wall 12 therealong is. greater than the inner diameter of wall 22 whereby a positive sealing engagement is assured between the'closure member and: the spout. When the spout wall 12 is made of polyethylene or of a substance having similar physical characteristics as the closure member, a live seal is effectuatedbetween the respectiveparts.

In order to provide the closure member with hinge and swivellable characteristics relative to spout 12, there is provided a cooperating mounting device or frame for removable application to the spout.

The frame, as shown, consists of a centrally apertured disc 29 provided with a rear. extension apron 30 having along the rearof the side edges a pair of aligned lugs each indicated by numeral 3-1, said lugs having aligned cylindrical. openings each indicated: by numeral 32 and with a diameter sufiici'ent 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 a width to permit apron 27 to' slide therethrough.

As shown in Figure 6, disc or frame 29', which is made of any suitable material but preferably resilient plastic such as. polyethylene or a vinyl for accommodating differences inspout diameter, is applicable over spout 12 and is based on shoulder portion 19 thereof for swivellable. engagement. Frame 29 is further more capable of removability whendesired from the spout.

As best shown, in. Figure 6, rod 28 is-removably insertableby lateral linear motion into the aligned openings 32 of lugs 31 while notches 33 permit clearance for linear movement of apron 27 therethrough. In this fashion lugs 31 permit the closure member from rod 28 to be hinged adjacent to thelip-ofi the spout 12 for opening and closing purposes. The type of hinging described permits full withdrawal of the closure member from frame 29 and further permits the closure member when inoperative position to. lie flat on cover wall 11.

Althoughframe 29 with the closure member mounted. thereon is capable of being' more easily swivellable while the closure member is in open position, nevertheless, swivelli'ng may be accomplished with the closure member in closed position.

As shown in Figure. 1, it is to be observedthat the width of apron. 27 is less than the distance between the inner walls of lugs 31 to permit rotation of rod 28*within the cylindrical openings 32 for approximately 180 degrees.

'lloioperr the closuremember, the underside of removal tab 25=may. be:- grasped by the thumb while the index finger bears against central wall 20. In this way, the seal be tween spout 12 and the engaging walls of the grooved rim is gradually and successively broken in a peelingoff manner; and when there is full disengagement, the closure member remains hingedly, rotatably and removably secured relative to spout 12. For removal relative to frame 29, the closure member is set at a degree angle with respect to the horizontal plane.

For sealing purposes, the closure member is swung towards closed position on red 28" about lugs 31 and the operation is most suitably completed by continuous sliding finger pressure along the top groove wall 23 from the rear forwardly.

it is to be observed that spout 12 is tall enough above shoulder 19 to. receive in: astacked relationship one or more identical frames for one or more identical closure members except for the modification by perforation of the central wall, the second frame member herein shown being indicated by the same numerals as the first except with post-script. letters 71 added in connection with the strainer closure member for application to frame 29a, the central wall 20a thereof is provided with perforations and the remaining structure is identical: and indicatedby the same numerals as the sealing closure member except with post-script letters a" added.

As shown in Figures 1 and 2 the mounting members 29 and 29av are applied tospout shoulder 19 in relative superposing: relationship and the straining and sealing closure members are capable of being introduced into the lugs interchangeably. The frame members preferably are positioned at 90 degrees apart; Figure 1 shows the closure members in open position, but they maybe swung bacle' to.-overlie wall. 11 by overcoming the sliding friction between the respective rods 28 and 28a and the openings 32 and 32a of lugs 31 and 31a. Figure 2 shows the straining; closure. member in closed position while the sealing closure member is in. open position. Figure 3 shows the sealing closure member in closedv position and the straining closure member in open position.

Vessel 10'shown in Figures 1, 2 and 7 may be used as an alternate beverage shaker and dispenser provided with a strainer, Figure 4 showing the device in the process of pouring contents thereof through the strainer closure member.

It is'to be observedthat the thickness of frames 29 and 29a are at a minimum to suit requirements and the elevation of frame 29 over 29a will not affect closure registration with spout 12 since the yieldability of apron. 30 serves in a: compensatory manner.

Modifications of the invention are shownin Figures 7-11..

In Figure 7 isshown a fiat closure member Ahaving two offset pairs of lugs as indicated by numerals 34' and 35. The sealing closure member and the straining closure member are respectively applicable to the respective lug pairs. The spout ofvessel A isindicated by numeral 36 and as shown is tapered. Figure 8 shows the cover member A of Figure 7 having the sealing'closure member in closed: position and engaging the lugs 34.

Figure 11 is a modified form of frame member indicated by numeral 37- and has a pair of offset aprons 38 and 39 extending outwardly and as shown at 90 degrees to each other. Each of said aprons has a pair of lugs indicated by numerals 40' and 41, the said pairs of lugs having respectively aligned cylindrical openings 42 and 43 and top notches 4-4-and 4-5: respectively for accommodation of rods 28' and: 28a of the sealing and straining closure members. Frame member 37 is removably and swivellably. applicable to any type of. spout but as shown in Figure 10 is applied to a: shoulder 46 of a neck 47 of a typeof salt cellar 48.

Thus. has been. described a; straining and sealing assembly'w'herein the closure membersare. selectively operable on a single. spouti for sealingand: straining. or sieving purposes.
