Patent No. 3767829A: Method For Warming Carbonated Beverages In Sealed Containers

patent-logo
Today in 1973, US Patent 3767829 A was issued, an invention of Fred A. Karr, for his “Method for Warming Carbonated Beverages in Sealed Containers.” There’s no Abstract, although in the description it includes these claims:

A method and apparatus are provided for continuously heating to ambient temperatures the contents of a plurality of sealed containers (e.g. bottles or cans) filled with carbonated beverage (e.g. beer and carbonated soft drinks). The method is useful as applied to containers freshly filled with cold carbonated beverage to avoid the formation of condensation on the containers. The method is also applicable to heating a beverage to pasteurizing temperatures from either cold filling or room temperature.

One embodiment of the apparatus include a conveyor formed of an endless perforate heat-resistive conveyor having upper and lower runs, and an elongated open-bottomed tunnel oven disposed above said upper run having side walls adapted to retain beverage containers carried by said upper run. Elongated stationary, dry-heating means disposed between upper and lower conveyor runs below the oven means are provided to supply a plurality of beverage containers to the upstream end of said upper run for movement through said oven. In this manner, the underside of the beverage containers are preferentially heated. Control means are associated with the heating means capable of adjusting the heat intensity along the container path of travel. One embodiment of the dry heater means includes a plurality of infrared heater elements transverse to the direction of travel of the conveyor with each element including an upper heat radiating surface and air-fuel gas mixture feed. Another embodiment of the dry heating means includes a plurality of spaced apart rows of open-flame natural draft burners capable of impinging upon the underside of the beverage containers.

In another embodiment of the apparatus, the conveyor is of vibratory type. The upstream end of the deck of the vibratory conveyor is disposed proximate and transverse to an infeed conveyor and the discharge end of the deck is proximate and transverse to a discharge conveyor so that the containers are conveyed directly to and from the conveyor deck without the interposition of a deadplate.

According to the process, the sealed containers filled with carbonated beverages are moved on a conveyor of one of the above types over a dry heat source so that the dry heat emitted therefrom impinges upon the underside of the containers to heat the carbonated beverage therein in progression proceeding from the bottom toward the top of the containers so that an elevation of the temperature of the beverage is induced while permitting the head space to remain relatively cool. Heating the beverage before the gaseous head space reduces the danger of superheating the gaseous head space and also eliminates the requirement of transmitting heat through the poorly-conductive gaseous head space in order to warm the beverage. The containers on a vibratory conveyor are vibrated sufficiently to increase heat transfer by convection from the bottom toward the top of the container.

In general, it is an object of the present invention to provide a method and apparatus for warming carbonated beverage in containers of either the glass bottle or metal can type to avoid the formation of condensation on the containers.

It is another object of the invention to provide a method and apparatus elevating the temperature of beer in a container of the above type to a value at which pasteurization can occur and which also overcomes the disadvantages of the prior art.

Patent No. 2124959A: Method Of Filling And Closing Cans

patent-logo
Today in 1938, US Patent 2124959 A was issued, an invention of William Martin Vogel, for his “Method Of Filling And Closing Cans.” There’s no Abstract, although in the description it includes these claims:

This invention relates to cans and a method of making and filling the same, and has for its object the provision of means whereby a maximum quantity of air may be evacuated from the can prior to the sealing operation.

At the present time beer is being packed in cans and one of the greatest difficulties encountered is that of completely or at least nearly completely evacuating the maximum quantity of air from the can. The failure to uniformly evacuate the air results in lack of uniformity of the contents of the can. In some cases an opened can produces beer of a decidedly fiat appearance and taste; while in other cases, an extremely frothy, aerated fluid emanates. Experiments have shown that this lack of uniformity in canned beer is apparently due to the failure to eliminate or evacuate the greatest possible amount of air from the can during or after the filling operation, and prior to the sealing of the can.

The primary object therefore, of this invention, is to provide a can of such a construction, together with a method of filling and sealing such a can, which will eliminate the maximum quantity of air from the can, thereby completely, or nearly completely, filling the can with the liquid contents only. More particularly, the invention contemplates the provision of a can initially formed with an outwardly distended or dished bottom,

arranged to be reversely curved or distorted under pressure after the can is filled, thereby causing the liquid contents of the can to be bodily shifted toward the top of ‘the can, causing said contents to displace and eject the air out of the can just prior to the sealing of the top of the can.

Patent No. 3258288A: Can Carrier

patent-logo
Today in 1966, US Patent 3258288 A was issued, an invention of Lawrence L. Courter, for his “Can Carrier.” There’s no Abstract, although in the description it includes this summary:

My invention relates to devices for carrying containers and more particularly .relates to devices for grasping a plurality of the ordinary beaded-top type of can by their tops and thus enabling them to be transported in a group.

The uses of the invention may be particularly considered with respect to beer cans, although of course cans containing other commodities may equally well be picked up and carried by my carrier. A feature of present day merchandising of beer is that not only are cans used in place of bottles, but the cans are frequently sold in units of six cans, called picnic-packs or party-packs. These units are customarily put up in paperboard containers of egg-crate construction, having a bottom and four side walls and compartment dividers, and having two opposed walls continued upward and bent inwardly to form handles. Unfortunately such unit carriers do not stack particularly well, and being made of cardboard they can not sustain exposure to dampness such as might result from refrigeration by ice or ice-water. Furthermore their bulk when empty is the same as when full, and when discarded on beaches and picnic grounds they make an unnecessary and unsightly clutter.

It is an object of my invention to provide a carrier of flat configuration which will permit the so-called picnic packs .to be stacked one on top of another.

Another object of my invention is to provide a carrier which, when stacked, is substantially flat on its upper surface except only for centering rings for positioning cans in a superimposed layer.

A further object of my invention is to provide a carrier having hooks for lifting cans and flanges cooperating with the hooks to maintain the hooks in contact with the beaded rims of the cans.

Still another object of my invent-ion is to provide a carrier of limited flexibility, capable of being snapped on with a single pressure motion to a suitably grouped number of cans, and capable of releasing one can at a time as it may be called for.

Another object of my invention is to provide a carrier which covers the minimum area of cans carried thereby and none at all below the upper ends of the cans, so that the cans are practically fully exposed for rapid refrigeration, or advertising.

A further object of my invention is to provide a plastic carrier which may be used with cold water to refrigerate cans, and which yet contains so little material that it is economically practical.

Still another object of my invention is to provide a flexible carrier having a handle so constructed and so secured to the body of the carrier that it will normally lie in the plane of the body and yet may be lifted to a carrying position, due to flexibility of the material.

John Updike’s Paean To The Beer Can

beer-can
Today is one of my favorite author’s birthdays, John Updike. He grew up in the same small Pennsylvania town that I did — Shillington — and we both escaped to a life of writing. Though I think you’ll agree he did rather better than I did with the writing thing, not that I’m complaining. I once wrote to him about a harebrained idea I had about writing updated Olinger stories from the perspective of the next generation (his Olinger Stories were a series of short tales set in Olinger, which was essentially his fictional name for Shillington). He wrote me back a nice note of encouragement on a hand-typed postcard that he signed, which today hangs in my office as a reminder and for inspiration. Anyway, this little gem he wrote for the The New Yorker in 1964 is a favorite of mine and I now post it each year in his honor. Enjoy.

Beer Can by John Updike

This seems to be an era of gratuitous inventions and negative improvements. Consider the beer can. It was beautiful — as beautiful as the clothespin, as inevitable as the wine bottle, as dignified and reassuring as the fire hydrant. A tranquil cylinder of delightfully resonant metal, it could be opened in an instant, requiring only the application of a handy gadget freely dispensed by every grocer. Who can forget the small, symmetrical thrill of those two triangular punctures, the dainty pfff, the little crest of suds that foamed eagerly in the exultation of release? Now we are given, instead, a top beetling with an ugly, shmoo-shaped tab, which, after fiercely resisting the tugging, bleeding fingers of the thirsty man, threatens his lips with a dangerous and hideous hole. However, we have discovered a way to thwart Progress, usually so unthwartable. Turn the beer can upside down and open the bottom. The bottom is still the way the top used to be. True, this operation gives the beer an unsettling jolt, and the sight of a consistently inverted beer can might make people edgy, not to say queasy. But the latter difficulty could be eliminated if manufacturers would design cans that looked the same whichever end was up, like playing cards. What we need is Progress with an escape hatch.

Now that’s writing. I especially like his allusion to the beauty of the clothespin as I am an unabashed lover of clothespins.

In case you’re not as old and curmudgeonly as me — and who is? — he’s talking about the transition to the pull-tab beer can (introduced between 1962-64) to replace the flat punch-top can that required you to punch two triangular holes in the top of the can in order to drink the beer and pour it in a glass.

The pull-tab (at left) replaced the punch top (right).

Originally known as the Zip Top, Rusty Cans has an informative and entertaining history of them. Now you know why a lot of bottle openers still have that triangle-shaped punch on one end.
church-key

So essentially, he’s lamenting the death of the old style beer can which most people considered a pain to open and downright impossible should you be without the necessary church key opener. He is correct, however, that the newfangled suckers were sharp and did cut fingers and lips on occasion, even snapping off without opening from time to time. But you still have to laugh at the unwillingness to embrace change (and possibly progress) even though he was only 32 at the time; hardly a normally curmudgeonly age.
