July 6, 1965 w. MILLER NON-SPILL VENTED CLOSURE FOR HOT CUPS 2 Sheets-Sheet 1 Filed April 10. 1961 INVENTOR WILLIAM L.. MILLER- IV 225 ATTORNYS July 6, 1965 FiledApril 10. 1961 w. L. MILLER NON-SPILL VENTED CLOSURE FOR HOT CUPS 2 Sheets-Sheet 2 WIILLI INVENTOR M L. Mmuaz ATTORNEYS 3,193,130 NON-SPILL VENTED CLOSURE FUR HUT CUPS William L. Miller, Skolde, llL, assignor to Continental (Ian Company, Inc, New York, N.Y., a corporation of New York Filed Apr. 10, 1961, Ser. No. 101,979 6 Claims. (Cl. 220-44) The invention relates generally to closures for beverage containers, and more particularly seeks to provide an improved closure for cups in which hot beverages such as cotfee are packaged for carry out sales.

When a paper cup or other container is filled with a hot beverage, such as coffee or the like, and capped with a lid or closure of paper or plastic or combinations thereof, said lid must be provided with some means through which excess vapor coming off the hot liquid fill can escape to the atmosphere. It is known to provide a small hole or holes in such lids at center portions thereof for this purpose. Such venting means serves the intended function, but, at the same time drops of the liquid contents can ooze through the venting and present a messy appearance at the top of the closure. A purpose of the invention is to provide a novel closure structure wherein provision is made for permitting escape of vapor to the atmosphere while hiding unsightly markings on the closure brought about by liquid seepage, and also preventing objectionable outspilling of liquid.

Another object of the invention is to provide an improved closure of the character stated wherein attaching media are provided by which attachment to a cup or other container may be effected, and floor, surrounding bead and cover means are provided cooperating in the provision of a vapor and liquid seepage receiving compartment or chamber, together with vapor e ress orificing opening through the floor into the chamber, the cover being disposed to close over and'hide any unsightly marking on the floor resulting from liquid seepage into the chamber, and provision also being made for the escape of vapor from the chamber past said cover.

Another object of the invention is to provide an improved closure of the character stated wherein the provision for vapor escape from the chamber past the cover is by way of restricted passage about edge portions of the cover means.

Another object of the invention is to provide an improved closure of the character stated wherein the provision for vapor escape from the chamber past the cover is by way of restricted orificing of the cover means.

Another object of the invention is to provide an improved closure of the character stated wherein the cover is a free disk having its peripheral edge supported on shelf ;means formed on the bead and snapped in place under inwardly directed overlying projections formed on said bead, said bead also having venting clearances formed therein at circumferentially spaced intervals about the ber floor and the overlying cover disk are bonded together at central portions and the peripheral margin of the disk rests in vapor pressure displaceable contact on the charm ber defining bead.

A still further object of the invention is to provide an improved closure of the character stated wherein the United States Patent chamber floor has a venting orifice in an upstanding protuberance spaced downwardly from the overlying cover and defining a surrounding annular Well in the chamber between floor, bead and cover, the cover being bonded to the bead and having a venting orifice therein inwardly of said bonding.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawings.

In the drawings:

FIGURE 1 is a top plan view illustrating a preferred form of the invention.

FIGURE 2 is an inverted plan view.

FIGURE 3 is an enlarged fragmentary sectional view taken on the line 3-3 on FIGURE 2.

FIGURE 4 is a cross sectional view illustrating a m0di fied form of a closure.

FIGURE 5 is a fragmentary sectional view illustrating the beaded floor portion of the closure body with the cover disk which is to cooperate therewith, the condition of the floor portion and disk prior to attachment thereof one to the other being illustrated.

FEGURE 6 is a fragmentary sectional view illustrating another form of the invention.

FIGURE 7 is a fragmentary sectional view similar to FIGURE 5 and showing the relation of the floor portion and the cooperating cover disk prior to attachment one to the other in the manner illustrated in FIGURE 6.

FlGURE 8 is a fragmentary sectional view illustrating another modification of the invention.

FIGURE 9 is a fragmentary sectional view showing the floor portion and cooperating cover disk of FIGURE 8 prior to attachment of the cover disk to the bead as shown in FIGURE 8.

FIGURE 10 is a fragmentary sectional view illustrating another modification of the invention wherein the cover disk is snapped into receiving grooving in the bead and is edge notched to provide for vapor venting.

In the form of the invention illustrated in FIGURES l to 3, the improved closure includes a disk-like body 5 having provision at its periphery, as generally indicated at 6, for attachment to a hot cup or other container generally designated 7. It is to be understood that the closure covered herein preferably is all plastic, vacuum formed structure, but the same may be formed as a composite of plastic such as polystyrene and paper.

The cup generally designated 7 and in which a hot beverage such as coffee may be packaged for carry out sales, in this illustration includes the usual body wall 8 which is flared as at 9 toward its open mouth defined by the outwardly turned curl 10. While the closure attaching means at the periphery of the closure may take various forms, in the present disclosure the same includes a heel or plug wall portion 11 receivable in the fiare of the body as illustrated in FIGURE 2, a channel 12 to receive and embrace the cup mouth curl 1t), and an outer skirt portion 13. The skirt is shown as equipped with inwardly projected flexible and deformable detents 14 for yieldably engaging under the curl it in a manner for removably securing the closure on the cup as shown in FIGURE 3.

The closure body may be equipped with one or more annular strengthening ribs 15, and it is also formed to include an upstanding annular bead generally designated 15 and which defines therewithin a floor portion 17 preferably including a raised central portion 18 having a dished top 19 equipped with a venting orifice 20. The raised central portion presents an annular dam wall 21.

The floor portion 17 joins the rib 16 through an outwardly and upwardly sloping annulus 22, the juncture of the sloping annulus providing a supporting shelf or groove 23 on which to support the peripheral edge of a cover disk I 24, as shown in FIGURE 3. It will be apparent that the disk 24 andthe floor portion 1'7; cooperate in defining a.

chamber or Compartment which is accessible withthe interior of a cup or other container on which the closure is mounted through the orifice 2t f The rib or bead 16 also is equipped with a plurality of inwardly directed, circumferentially' spaced overhanging vdetents 25 under which the peripheral edge portion tain the cover disk in place in the manner illustrated in' FIGURE 3. .A plurality of circumferentially spaced shelf portions 26 also are formed in the sloping'annulus 22, said shelf portions beingspaced downwardly from the 'of the flexible disk 24.i s snapped and which serve to reoverlying cover disk marginin the manner illustrated at the right in FIGURE 3, and saidshelfportions merge outwardly into upwardly directed indents 27 formed in and spaced circumferentially about the closure bead, said shelf portions 26-and the indents 27 serving to .provide for venting of vapors from the chamber between the cover .disk 23 and the floor portion .17'and about the peripheral edgeof the disk as indicated at 23. Q I

It will be apparent from the foregoing that hot vapors fromthe hot beverage contained in the, cup 7 will be vented through the orificing 26 into'the chamber formed between the closure -floor..portion' 17 and the overlying cover disk 24, and such vapors may escape from the chamber about 'the peripheral edge portion of the disk through the venting passages defined at 26-27, and as indicated at 28. Any seepage of liquid through'the orifice 20 will be trapped in the chamber above thefioor portion 17, and the cover disk 24 will hide any unsightly appearance of the floor portion 17 which might be brought about by the seepage of liquid'into the closure chamber,

and it will be apparent thatthere can be no objectionable ofhvapor pressure which willbe effective to minimize liquid seepage back through the-orifice 34 into the cup.

' Also, as in the previously described form, the cover disk will 'prevent any objectionable outspilling of liquid which may have seeped into the closure chamber or compartment. V

The condition of the closure disk 35 andthe cooperating floor portion 33 prior to bonding of central portions thereof together as at 36 inFIGURE 4 is shown in FIGURES. V 5

In the form of the invention shown'in FIGURES 6 and 7 the closure body 38 includes the'upstanding bead 39 and the floor portion 40 having the central raised portion 41 presenting the damming wall 42. The floor portion 49 also is equipped with a venting orifice'at 43. As in the form. of FIGURE 4, the cover disk 44 is bonded at 45 to a central portion of the floor-portion, in this instance onthe central raised portion 41, the 'peripheral'edge of the disk resting upon the beadj 39 and being displaceable in the manner and'for the purpose described in connection with FIGURE 4. V

The condition of the closure disk 44 and the cooperating floor portion 40prior to the bonding'thereof together centrally at 45 is shown in FIGURE'7.

In the form of theinvention illustrated in FIGURES 8 and 9 the closure body 47- includes the upstanding bead 48 and the floor portion 49, the latter having a central outspilling of liquid which may so seep into the chamber.

It will be obvious that the cover disk 24, in addition to hiding any unsightly appearance of the underlying closure floor'portionv 17, will remain relatively cooler than the main body of the closure which may be directly contacted by hot liquid within the cup or container. Therefore, the vapor, as it escapes into the chamber closure or compartment, comes in contact with the relatively .cool cover disk and tends to condense. .This reduces the amount of hot vapor to escape to the atmosphere-and.

reduces the possibility of the cappergetting a vapor burn on 'his hand as he places the closure on the container.

In the form of the invention illustrated in FIGURES 4 and 5; the closure body 29 includes the strengthening rib 30 and theattaching means generally designated 31,

as in the previously'described form; This closure also includes the upstanding head 32 and the floor portion 33, the latter being provided with a venting orifice at 34.

In this form the cover disk 35 is bonded centrally to the 7 floor portion at 36, said disk and floor portion being :dishedout of the normal planes in being brought together during the central bonding as illustrated in FIGURE 4,'

thus to yieldably hold the peripheral edge portion 37 of the disk against the upper extremity of the bead as a Vapor pressure displaceable venting means; .Also, the

upwarddeformation of the floor portion 33, as indicated 1 in FIGURE 4, provides a damming eifect and a chamber whichis deepest at the peripheral portion thereof. Any

liquid seeping through the orifice 34, will be trapped in the chamber, and the floor portion 33 which might take on a messy appearance asthe result of a liquidseepage will be hidden by the cover disk 35. Vapor ventinginto the chamber between the floor portion 33 and the cover.

disk 35 mayescape by pressure displacement of periph-' eral edge portions 37 of the disk 35 from the supporting:

head or rib, 32, and the yieldable retention of the disk periphery against the bead will serve totrap ameasure raised portion'50 presenting a damming wall 51 and having a central ventin'gorifi'ce at 52." The cover disk 53 has a venting orificeat 54 and its peripheral margin is bonded at "55 to the upper extremity of the upstanding bead 48. As in the other forms, a vapor and seepage receiving chamber is provided between the floor portion 49 and the overlying cover disk 53, the cover disk serving to hide any messy appearance of the floor portion dueto seepage of liquid into the chamber, and vaporventing being provided for-at 52 and 54. 7

' The condition of the floor portion 49 and the cooperating cover disk '53 priorto thebonding at 55 is shown in FIGURE 9. a

Another modification is illustrated in FIGURE 10, and in this form, the closure body 56 is equippedwith a raised annular'bead' 57 as in the other forms, and the floor portion 58, vented in a manner similar to the other disclosures wholly formed of plastic, or the main body may be formed of plastic and cover disks of paper may be employed. In the bonding of the cover disksto the floor portion, or to particular portions, any suitable adhesive may be employed. Where heat scalable materials are used,'the bonding may be by heat sealing, or'whereplasties are employed, volatile solvents .may be employed in providing the desired bonding.
