Patent No. 2325309A: Process Of Capping Bottles

patent-logo
Today in 1943, US Patent 2325309 A was issued, an invention of Jan De Swart, for his “Process of Capping Bottles.” There’s no Abstract, although in the description it includes these claims:

This invention has to do with sealing caps for bottles and the like, as well as bottle sealing methods.

In its more particular contemplates a hard and substantially non-flexible plastic cap which is so constructed, of a plastic capable of being rendered temporarily pliable and remolded, as to be applied in sealing relationship to a bottle without injury to the cap and which not only is capable of sealing the bottle against substantial pressures but which also compensates for the cold flow characteristics prevalent in most plastics.

I am aware that attempts have been made to produce a successful thermoplastic bottle cap but so far as I am aware, no such cap has been produced which is capable of general use to cap bottles containing fluids such as carbonated beverages, beer or the like. Such prior caps have been incapable of maintaining an effective seal where substantial pressures are generated in the bottle; and have been incapable of withstanding the temperatures incident to pasteurization processes. For instance, pasteurization processes commonly utilize temperatures of the order of 160 produced do not maintain a seal under such conditions. Another shortcoming of prior caps has been the fact that they fail to maintain an effective seal after the plastics of which the caps are made have undergone the normal cold flow.

It is among the aims of my invention to overcome those shortcomings and, generally speaking, I accomplish this by providing a cap preformed of a cold-setting plastic capable of being rendered temporarily pliable and then reformed and re-hardened about the neck of a bottle. An important characteristic of my improved cap resides in the fact that its side Wall presents a peripheral bead of relatively thick cross-section and having a. relatively low setting rate which, after being temporarily softened, is remolded to aspects, my invention the contour of the external marginal bead forming a part of the conventional beer or carbonated beverage bottle. This bead portion undergoes cap into sealing relationship with the neck or more and thermoplastic caps heretofore l the provision of a plastic cap having a construction which provides a double seal.

Another object is the provision of a cap having a guiding formation to guide it onto a bottle during capping.

Patent No. 3895478A: Roll On Capping Head

patent-logo
Today in 1975, US Patent 3895478 A was issued, an invention of Kenneth F.M. Friendship, assigned to Continental Can Co., for his “Roll On Capping Head.” Here’s the Abstract:

A roll on type capping head for applying closure cap blanks to the mouths of containers, such as bottles, jars or cans, which is characterized by a non-rotatable inner spindle member supporting a cylindrical outer spindle assembly which is rotatable about the axis of the inner spindle member and which carries cap skirt-engaging rollers adapted to be cammed into engagement with portions of the skirt on the cap blank so as to shape it to the contour of the threads on the container neck and to form a pilfer-proof ring thereon. The head is mounted for vertical reciprocation between operative and inoperative positions and the operation of the head and rollers is effected by a pneumatic spring arrangement with a no-cap no-roll operation feature.

Patent No. 3260395A: Bottle Cap

patent-logo
Today in 1966, US Patent 3260395 A was issued, an invention of Nicholas D. Ellis, assigned to Anheuser Busch, for his “Bottle Cap.” There’s no Abstract, although in the description it includes this summary:

This invention relates to an improved bottle cap which can be removed from a bottle by hand without the aid of a bottle opener. This bottle cap may be applied to bottles, such as beer or soda bottles, in the conventional manner with existing high speed automatic capping equipment. Further, this bottle cap may be removed if desired by conventional bottle openers which are in use today.

Bottle caps which require no separate opener, or so called self-opening bottle caps, are generally old and are of different design. Some of these bottle caps have a tongue which extends downwardly from the depending skirt and others have constructions which make them difficult to handle in a hopper and to use on the high speed automatic bottling equipment which exists in many bottling shops or plants today. Others of these self-opening bottle caps have a tongue struck from the metal cap itself which is pulled completely free of the cap when opening, with the result that the remaining portions of the bottle cap are propelled like a rocket and cause property damage or cause personal injury. This frequently happens when the bottle cap is removed rapidly so that the tongue portion remains in the lingers of the person opening the bottle, but the remainder of the bottle cap is free to y upwardly or away from the bottle. Still others cannot be opened in the conventional manner with bottle openers if desired. And others result in the cutting of the fingers with sharp metal edges When opening.

The principal object of the present invention is to provide a self-opening bottle cap which can be used in existing bottle cap handling apparatus and bottle cap machines for application to bottles, said bottle cap comprising an outer shell, an inner disc, and a seal adapted to seal the bottle cap to the bottle and to prevent the outer shell and inner disc from separating either before or after the bottle cap is removed. Another object is to provide a self-opening bottle cap, a tongue having a rounded edge which protects the lingers against cutting and which is not pulled off in its entirety, so that the removed bottle cap remains in the hands of the person opening the bottle. This prevents the pressure in the bottle from propelling the cap or parts thereof at great speed. Another object is to provide fewer scores in the depending skirt of the bottle cap hereinbefore described, thereby reducing the possibility of splitting the score during the crowning operation so as to create a leaker. Another object is to provide these advantages in a bottle cap which can be removed by a conventional bottle opener if desired.

Patent No. 996972A: Apparatus For Filling Bottles

patent-logo
Today in 1911, US Patent 996972 A was issued, an invention of Frank L. Caris and Clarence J. Gardner, for their “Apparatus For Filling Bottles.” There’s no Abstract, although in the description it includes this summary:

This invention relates to apparatus for use in filling bottles from kegs or barrels, the same being particularly adapted for bottling beer and the like.

One of the objects of the invention is to provide an inexpensive device of this character which can be readily handled by one person, there being improved means for discharging the liquid into the bottle and for permitting the escape of foam back to the keg or other receptacle from which the liquid is drawn.

A further object is to provide apparatus of this type having a nozzle in which is mounted a valve normally maintained in closed position but which can be conveniently held open during the filling operation. With the foregoing and other objects in view, the invention consists in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

Patent No. 3586514A: Thin-Walled Plastic Container For Beer

patent-logo
Today in 1971, US Patent 3586514 A was issued, an invention of Taco Vijlbrief, assigned to Heineken Tech Beheer NV, for his “Thin-Walled Plastic Container For Beer.” There’s no Abstract, though it’s described this way in the application:

SUMMARY OF THE INVENTION According to the present invention, it has been found that a thin-walled container specially suitable for beer and other oxygen-sensitive materials is obtained by having a hard polymer or copolymer of vinyl chloride containing such a quantity of anti-oxidizing agent that the oxygen permeability of this hard polymer or copolymer, measured as the number of cm. of oxygen of standard temperature and pressure which has passed through 1 cm. of the plastic through a thickness of 1 mm, per second, per cm. of oxygen overpressure at 20 C. (mercury), amounts to about 10- cm. (STP)mm./cm. sec., cm. Hg or lower.

By thin-walled throughout the specification and claims is understood that the thickness of the wall does not exceed 2.5 millimeters. Thicker walls present working difficulties and moreover, the problem of undesired oxygen permeation through the wall is felt only if the wall is thin.
