Cl. 62-457 27 Claims ABSTRACT OF THE DISCLOSURE The device chills a bottle and its contents while displaying the bottle and its label vertically. It has a pair of cold capsules containing freezable liquid, each having a cupped inner vertical bottle-engaging wall, an outer vertical arcuate wall, and arcuate vertical end walls. Support means hold a bottle and the two capsules vertically with the capsules nearly meeting at the rear of the bottle and with the label displayed at the front. A receptacle in the support means collects condensed moisture, and cam means enables the end walls of the capsules to swing the capsules toward and away from each other to accommodate different bottle sizes, while retaining them otherwise in approximately the same positions. A wedge or spring holds the bottle snugly against the inner arcuate walls of said capsules.

This application is a continuation-in-part of application Ser. No. 596,255, filed Nov. 22, 1966 and now abandoned.

This invention relates to a bottle-cooling device.

Our new device maintains the temperature of wines and the like when they are served in a restaurant. Our device is placed on the table and a bottle of wine, previously cooled to the correct temperature in a special refrigerator, is then placed in our device.

One object of the invention is to maintain the temperature of the wine at approximately the same temperature as that of the special refrigerator in which it is stored prior to serving (about 37 F.). After the bottle has been opened and part of the contents poured into glasses, the partially filled bottle is returned to our cooler to maintain the temperature until the remainder of the contents of the bottle is consumed.

Another object of the invention is to accomplish this cooling while at the same time conveniently displaying the label.

A further object is to provide a cooling device more convenient to use than is the conventional wine cooling bucket, where the bottle is buried in cracked ice both prior to serving, and, by present practice, after part of the contents of the bottle are poured off. However, when a bottle is removed from cracked ice for the first servin the cavity in the ice from which the bottle was removed disappears, and it is, to say the least, not convenient to re-bury the bottle in the cracked ice, though that would have to be done for efliciently maintaining the temperature of the bottles contents.

A still further object of the invention is to provide a bottle cooling device that is more compact, more convenient to store, and less costly than the conventional ice :bucket. Our new device is small enough so that it can be used on crowded restaurant tables, in contrast to the relatively large ice buckets now in common use that frequently cannot be placed on a small restaurant table.

Another disadvantage of conventional ice buckets is that the general effect with ice is messy, and that the label tends to get washed off either by the melting ice or by condensed moisture. 'It is quite desirable to retain the label in place, and this is done by our new device.

The present invention is intended to provide an improved way of keeping bottles cool while displaying their labels. It employs a novel type of cold capsule which contains a liquid that can be frozen and, when frozen, can then be used for an hour or more to keep the contents of the bottle cool without any other refrigeration. Two such capsules are used with each bottle in a short holder that retains contact of the bottle with its chilling capsules, collects the small amount of moisture of condensation, and enhances the display of the bottles label.

An important feature of the invention is its adaptability to various sizes of bottles. Bottles come in many sizes and to tailor them exactly to one bottle would greatly limit the utility of the device. In the present invention, adaptability to bottles of various sizes is achieved in a novel and significant manner, utilizing a novel cam structure.

In a preferred form of the invention the cold capsules are supported by a holder which incorporates in a single molding a moisture-collecting receptacle and the cam structure. Moreover, with the addition of a short base pedestal, the holders are compactly stackable for storage.

Other objects and advantages of the invention will appear from the following description of some preferred embodiments.

The invention comprises an assembly for cooling a bottle while holding it in a vertical position and while collecting any dripping moisture due to condensation. It is adaptable to many sizes of bottles, and while the cooling capsule cannot on that account generally attain complete contact with the entire wall of the bottle, closeness is obtained with a considerable portion thereof.

One form of this invention shown in FIGS. 1 through 8 comprises a metal body member 10, a cam base 11, and a pair of

cold capsules

12 and 13, which are substantially idential to each other. The device holds a bottle 14 vertically and in close contact with the two

capsules

12 and 13, while displaying the label 15 prominently. Yet about two-thirds of the bottle periphery below the neck is sub ject to the cooling action of the

capsules

12 and 13.

The body 10 holds the

other elements

11, 12, 13, and 14 in their proper positions and serves a decorative function as well. Preferably, the body 10 is a receptacle of aluminum, brass, other metal, or plastic. Its bottom wall 16 may have a central opening 17 (FIGS. 6 and 8) for ease in washing and may be provided with a series of small openings 18 disposed around a circle, used for attaching the cam base 11 thereto, as described later. The bottom wall may also provide an outer and lower recessed rim portion '20 providing the actual contact with a table or other supporting surface. A short upstanding generally vertical wall 2.1 leads to a step 22, which is radially outset to a substantially vertical main wall portion 23. Both of the

wall portions

21 and 23 may, and preferably do, slightly diverge from the vertical for ease of manufacture, preferably between about two and five degrees. The wall 23 is preferably low at the front portion 24, to insure display of the label 15, and then curves upwardly in a pleasing fashion along a rim 25 to a higher rear wall 26, which gives the height needed for proper support of the

capsules

12 and 13.

The cam base 11 may be injection molded from plastic and provides a shallow, cup-like, moisture-collecting receptacle having a solid bottom wall 31 and an upturned lip 32. The receptacle 30 stands on a plurality of legs or studs 33, which preferably are hollow and overlie the openings 18 through the bottom wall 16 of the body 10. Screws or rivets 34 may be inserted from below to secure the cam-base legs or studs 33 tightly to the bottom wall 16. Other means of fastening may, of course, be used. The receptacle 30 is relatively shallow but is suflficient to collect the moisture of condensation, which is all the moisture it will be called upon to collect, especially since it is shaped to provide a pair of

wells

35 and 36 which approach and even may join into each other at the rear and in which the

capsules

12 and 13 rest. The

wells

35 and 36 are defined by the outer wall 32 and by a specially shaped inner wall 37. The arcuate outer wall 32 has substantially the outer peripheral shape as the wall 23 and may fit relatively snugly into it. Each inner wall 37 is provided with

end cam portions

38 and 39 which are part of the same are and each may have for strength purposes only, a pair of arcuate

convex portions

40 and 41 meeting at a point 42.

The cam base .11 also has a raised front wall portion 44 with a flat, preferably inclined surface 45 to support a name plate 46, which may identify the displayer. An inclined wedgelike member 47 extends down preferably at about 45 to a flat portion 48 above the

wells

35 and 36. The smallest size of bottle 14 may rest on the portion 48, but all other bottles do not touch the portion 48 but rest on the wedge 47 and bear against the

cold capsules

12 and 13. The wedge 47 enables the various sizes of bottles to be inserted and still make the desired contact with the cold capsules. In place of the wedge 47, or in addition to it, if desired, a coil spring may be used in FIGS. 12 and 13.

The two

cold capsules

12 and 13 are identical, each comprising a hollow body 50, preferably of plastic, having a filler plug 51 in a bottom wall 52, through which the hollow body 50 is filled with a suitable cooling liquid 53, such as a water solution of glycerin or other well known cooling solutions, which can be frozen at a temperature somewhat below the freezing point of water. Its generally vertical walls comprise a pair of

arcuate end walls

54 and 55, an outer arcuate wall 56, and an inner generally arcuate wall 57. The

end walls

54 and 55 are of the same arcuate radius as the earns 38 and 39, meeting the inner and

outer walls

57, 56 by a curve. The outer wall 56 is provided at a convenient distance above the bottom wall 52 with a projection 58 which goes out to a very small radius portion 59, practically an angle, that engages the wall portion 26 of the body. The inner generally arcuate wall 57 preferably comprises two arcuate portions 57a and 5712 meeting at an angle at a groove 60. The top wall 61 may be constructed as shown, so that the body 50 fully encloses the liquid 53. Preferably the liquid 53 is frozen when the

capsule

12 or 13 is lying with its inner arcuate wall 57 down, so that the resultant ice hugs the wall 57 when in use, for this is where the ice is needed. This also means that part of the outer arcuate wall 56, particularly the projection 58 as well as some more, will have an air space until the cold solid melts, for the liquid 53 does not, of course, completely fill the body 50.

The cam base 11 is inserted into the body 10 and fastened by its screws or rivets 34 to the studs 33, being set so that its wedge 47 is centered with respect to the short front wall 24 of the body 10 and so that the partition between the two

wells

35 and 36 is directly in back at the high point of the body 10. The

cold capsules

12 and 13 are inserted with their bases 52 resting in the wells .35 and 36 and with their

arcuate end walls

54 and 55 respectively engaging the earns 38 and 39, which are (as said before) part of the same are. The

walls

40 and 41 touch the capsule wall 57 only at extreme positions of the capsule along the cam. Then when a bottle 14 is inserted, it bears against the

capsules

12 and 13, making two line contacts with each

capsule

12, 13, and also rests on the wedge 47 of the cam base 11. The line contacts are made with the cold capsules, because the

cold capsules

12 and 13 are free to pivot about the outer projection 59. The

walls

54 and 55 are always in contact with their

cams

38 and 39. This enables the

cold capsules

12 and 13 to adjust themselves to the size of the bottle 14 until each capsule achieves its two line contacts. The remainder of the

capsule

12, 13 while not in actual contact with the bottle 14, is very close to it and is sutficiently close to give the needed type of cooling action. Of course, if an actual standard size of bottle is available, it is possible to design the

capsules

12, 13 to make full contact with it over the entire inner surface 57 of the capsule, but this is generally not feasible, because even for a given manufacturer of a beverage, his bottle sizes vary somewhat in tolerance. Hence, it is not usually wise to limit the device so that it could hold only one size. The invention makes it possible to hold a wide variety of bottle sizes and obtain the proper cooling action. The swinging action and the cam shape enable the capsules to retain their proper position while properly engaging the bottle.

The forms of the invention shown in FIGS. 9 through 13 comprise a single plastic member 70 which in one molding unites the functions of the body and cam base 11. It has a solid bottom wall 71, a bottom support rim 72 beneath the bottom wall 71, and a solid side wall 73 somewhat like the wall 23. The bottom wall 71 is shaped to provide a pair of

wells

75 and 76 generally like the wells and 36. An integral raised portion 74 in its center provides a pair of

arcuate cam walls

77 and 78 which are spaced from, curve oppositely to, and are of generally the same radius as the side Wall 73. (The strengthening portions and 41 may be present if desired.) In the form shown in FIGS. 9 through 11, there is a wedge 79 like the wedge 47.

In the form of the invention shown in FIGS. 12 and 13, a coil spring 80 extends between

posts

81 and 82 and holds the bottle 14a or 14b firmly in contact with

capsules

83 and 84.

The

capsules

83 and 84 are like the

capsules

12 and 13, except that they do not have the recess 60. As in FIGS. l-8, so in these forms of FIGS. 9 through 13, the earns 77 and 78 act on the

end walls

54 and 55 of the

capsules

83, 84, which pivot about the projection 59. The effectiveness of their adaptability is shown in FIGS. 12 and 13.

A preferred form of the invention, shown in FIGS. 14 through 18, comprises a molded plastic unit 100 which in one molding unites the functions of the body 10, the cam base 11, and the wedge-shaped cam 47. The unit 100 has solid flat

bottom wells

101 and 102 divided by an integral raised portion 103 that provides a pair of

arcuate cam walls

104 and 105. The

walls

104 and 105 are spaced from, curve oppositely to, and are of generally the same radius as a cylindrical wall 106, which coop erates with the

wells

101 and 102 and the portion 103 to provide the moisture-containing receptacle. The cylindrical wall 106 preferably slightly diverges from the vertical for ease of manufacture, preferably between about two and five degrees and is preferably low at a front portion 107, to insure display of the bottles label 15, and then curves upwardly in a pleasing fashion along a rim 108 to a higher rear wall 109, which gives the height needed for proper support of the

capsules

12 and 13.

The portion 108 provides a raised generally fiat, preferably slightly inclined surface or front platform 110 to support a name plate like the plate 46, which may identify the displayer. An inclined wedge-like member 111 extends down preferably at about and then blends into a generally concave portion 112 above the

wells

101 and 102.

A narrow portion 113- of the portion 103 separates the

wells

101 and 102 and connects the concave portion 112 with a raised portion or rear platform 114 at the rear having an upward projection 115, used when stacking the units 100, as explained below. The front platform 110 and rear platform 114 are on the same horizontal level and are diametrically opposite each other.

In use, the

capsules

12 and 13 are put into the unit 100 exactly as they are used in FIGS. 1 and 2, and the bottle 14 is put in the same way too.

The units 100 are preferably made to be compactly stackable, and their stacking is improved by providing a pedestal 120 on the bottom, as shown in FIGS. 16 and 18. The pedestal 120 is metal, such as stainless steel, having a generally cylindrical wall 121, slightly tapering, and a bottom wall 122 which has an upwardly recessed central portion 123 surrounded by and above a base rim 124. The wall 121 has an outturned flange 125, which urges a gasket 126 against a shelf 127 on the inner side of the lower edge 128 of the wall 106. The unit 100 is provided with a depending central cylindrical socket 130 which is provided with internal threads, and a screw 131 is inserted through an opening 132 in the metal recessed Wall portion 123 of the pedestal 120 and screwed into the socket 128 to hold the pedestal 120 and gasket 126 in correct position.

Instead of the metal pedestal 120, a plastic pedestal 140 of FIG. 17 may be used. The pedestal 140 has a side wall 141, slightly tapering out from a base rim 142 that surrounds an upwardly recessed lower Wall 143. Attachment is again the same, though the device is made somewhat differently because of the nature of the plastic, and in this instance no gasket is needed, an upper flange 144 seating directly against the shelf 127, the flange 144 providing the necessary seating.

Whichever

pedestal

120 or 140 is used, the stackability is enhanced, as shown in FIG. 18, for the rim 124 (or 142) rests on the platforms and 1114 of the lower unit 100, and the upwardly recessed bottom wall po-rtions 123 (or 143) rest on the projection 115, which is the same height above the rear platform 114 as the wall portion 123 is above the rim 124. The recessing of the wall 123 (or 143) and dependency of the rim 124 (or 142) therefrom, prevents sidewise movement, and the gentle upward tapering helps too. A number of the units 100 can be stacked and held ready for use and unstacked one by one, as required.

The pedestal or assures that successive units will nest without turning over or rolling and gives excellent alignment.

To those skilled in the art to which this invention relates, many changes in construction and widely differing embodiments and applications of the invention will suggest themselves without departing from the spirit and scope of the invention. The disclosures and the description herein are purely illustrative and are not intended to be in any sense limiting.
