Patent No. 1100818A: Bottle Cap Remover

patent-logo
Today in 1914, US Patent 1100818 A was issued, an invention of Robert O. Boardman, for his “Bottle Cap Remover.” There’s no Abstract, though it’s described this way in the application:

This invention relates to bottle closures. and .more particularly to a device for removing the cap closures from beer bottles, and the like. As is well-known. such cap closures are ordinarily removed by the use of an implement entirely separate and distinct from the cap. Such opening devices are liable to be lost and misplaced, and even, when at hand must be applied to the cap prior to manipulation to pry the cap from it has been proposed to provide, as a substitute for such opening devices, a cap having an integral tongue designed to be grasped by the fingers and pulled to remove the cap, or to provide a cap constructed in sections, arranged to be separated to such an extent as to permit of removal of the cap without the use of the ordinary opener. Such caps, however, present the disadvantage that a special machine is necessary for their manufacture and usually they are not so constructed as to permit of the use of the ordinary capping machine. Furthermore, they are expensive to manufacture and can usually only be manipulated by a person capable of exerting a strong grip.

In connection with the foregoing it is the object of the present invention to provide a bottle cap opener so constructed that it may be readily assembled with the ordinary bottle cap at the time of placing the latter upon the bottle to be sealed, and may be readily and quickly manipulated by anyone for the purpose of prying oil the cap.

Patent No. 2348797A: Crown Cap Selecting Machine

patent-logo
Today in 1944, US Patent 2348797 A was issued, an invention of Louis A. Fischer, assigned to the Schaefer Brewing Co., for his “Crown Cap Selecting Machine.” There’s no Abstract, although in the description it includes this summary:

This invention relates to crown cap selecting machines, and has for its object to provide means for inspecting the interior of such machines while the same are running, and also provide means for preventing the caps from clogging during the operation of the machine.

In the use of such cap selecting machines, it frequently happens that inspection of the interior of the same becomes necessary and also that certain caps which have become clogged be removed. Also certain foreign matters must be dislodged.

This requires a shutting down of the machine and a re-starting, this requiring several hours of non-use of the machine.

The invention consists of a door closed opening which permits the caps to be ejected from the machine, capable of being opened and closed during the operation of the machine, and the invention also consists in the means for preventing clogging of caps.

patent-logo
Today in 2014, US Patent 8671802 B2 was issued, an invention of Chikamitsu Takagi, for his “Bottle Cap Opener.” Here’s the Abstract:

A movable outer cylindrical member and a movable inner cylindrical member are arranged vertically movably in a lower half of a cylindrical main body. By placing the movable inner cylindrical member on a bottle mouth and pushing down the cylindrical main body, a lower end of a hooking member is engaged with a lower end of the crown cap to pry the crown cap away. At the same time, the movable outer cylindrical member is moved up and a piston inside a cylinder arranged in an upper half of the cylindrical main body is moved up with the movable outer cylindrical member, so that the air in the cylinder is compressed, and a cover member is brought out in by the compressed air.

Patent No. 4782969A: Twist-Off Bottle Cap

patent-logo
Today in 1988, US Patent 4782969 A was issued, an invention of John C. Henning, for his “Twist-Off Bottle Cap.” Here’s the Abstract:

A tamper-proof closure is disclosed for use with a bottle having a neck, a lip with a downwardly and inwardly sloping peripheral wall and a plurality of outwardly extending ribs disposed at the juncture of the sloping wall and outer wall of the neck. The closure includes a top wall, a depending ribbed skirt and a plurality of rectangular tabs extending from the bottom edge of the skirt between each pair of ribs. The tabs are bent inwardly and upwardly and include a serrated edge for engagement with the ribs on the bottle. When the cap is applied, the tabs form compressive members holding the lid in sealed position against the bottle neck. The closure is removed by twisting, which causes the tabs to be shifted outwardly beyond the bottle ribs so that the cap can be lifted from the bottle. The closure cannot be reapplied since, during removal, the tabs have been bent outwardly to a point where they can no longer engage the bottle ribs.

Patent No. 2451273A: Method Of Applying Bottle Caps

patent-logo
Today in 1948, US Patent 2451273 A was issued, an invention of Elvin M. Bright, for his “Method of Applying Bottle Caps.” There’s no Abstract, although in the description it includes this summary:

This invention relates to improvements in a method for thermoplastically capping bottles.

It is an important object of the invention to provide a method and means of capping a bottle which, to a large extent, will make use of standard existing bottle capping equipment and will provide a cap which will not interfere with the handling, processing, merchandising, and use of the bottle and its contents in accordance with conventional procedure.

From the standpoint of the process involved, a very important objective is to soften a thickened margin of the bottle cap blank without softening the remainder thereof, and to mold such thickened margin around the cap-receiving bead of the bottle and immediately to harden it thereon. In this connection I propose to utilize infra-red rays or other radiant heat for softening the flange of the bottle cap blank while shielding and thermally insulating the top of the blank from such rays. Infra-red rays are preferred because of the ease with which they may be directed and controlled.

Patent No. 327099A: Bottle Stopper

patent-logo
Today in 1885, US Patent 327099 A was issued, an invention of William Painter, for his “Bottle Stopper.” Painter patented a number of bottle-related items, but is undoubtedly best known for having invented the first crown bottle top. There’s no Abstract, although in the description it includes this summary:

My invention is particularly designed for use with bottles or similar vessels containing fluids under pressure from eft’ervescence or otherwise; but it is adapted as well for use where such pressure does not exist.

Stoppers have heretofore been made secure against internal pressure in one of two ways by using a tie-wire, also by special stopperriety; or by placing the stopper inside the bottle and so arranging it that the stopper is forced against a seat or packing by the pressure within. The first of these methods is objectionable because of the expense, and in some cases the inconvenience of its use and liability of accidental opening, The second is so for the same reasons, and for the outside of the bottle is an obstruction to ready and effectual cleansing both of the bottle and stopper. Stoppers secured by external fastenings are retained solely by the power of the device to overcome the internal pressure. Those within the bottle are retained because they present a solid mass too large to pass through the bottleneck. In neither case referred to does the lateral expansion of the stopper itself against the interior of the bottle mouth enter as an element of its action in resisting internal pressure, as it does with stoppers made according to my method.

My invention differs from all others in the respects named. It is made of thin material, and placed within the bottle. neck or mouthward, so that it presents the resistance of an inverted arch or dome having its haunches supported by contact with the walls of the bottle-mouth, which are preferably indented or grooved to afford a more secure hold. Pressure upon an arch is always transferred in part as lateral pressure against its abutment, while a similar pressure upon a solid body having the same convexity does not tend to I displace the abutment laterally, but to shear of the bottle neck and stopper off the edges of such solid body. This physical principle illustrates the actual difference between my cup-shaped disk-stoppers and all others with which I am acquainted.

Patent No. 1974836A: Crown Cap Puller

patent-logo
Today in 1934, US Patent 1974836 A was issued, an invention of John M. Schilling, for his “Crown Cap Puller.” There’s no Abstract, although in the description it includes this summary:

My invention relates to an improved construction of cap puller for bottles having crown caps of the kind commonly used in connection with bottled beverages. My device is preferably constructed of a single piece of sheet metal formed to give it substantial support on an object to which it is attached, and at the same time to effectively engage one edge and the outer end of a bottle cap when the cap is being removed from the bottle by means of the device. Furthermore, my device is constructed so that it may be secured to a desired support by a single fastener, for example, a screw, and the device has extending from its body portion, a projection for engaging the outer end of the bottle cap at a point remote from the edge of the cap being removed from the bottle by the device, the distance between the cap removing portion of the device and said projection, being preferably substantially greater than half the diameter of the cap, to the end that the pressure’exerted upon the .bottle in removing its cap, may be reduced to a minimum. The projection on the device for engaging the outer end surface of the cap, may consist of an integral projection formed from the material of the device, or it may consist of a rounded head of the fastening device, as preferred, and where the latter construction is used, the device is of extreme simplicity and correspondingly cheap to manufacture.
