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.

Patent Nos. 3094213A & 3094214A: Fill-Height Inspection Device For Fluid In Bottles/Automatic Container Fill-Height Inspection Machine

patent-logo
Today in 1895, US Patent 3094213 A and US Patent 3094214 A was issued, both inventions of James H. Wyman, with the second also by Robert G. Husome, for their “Fill-Height Inspection Device For Fluid In Bottles” and “Automatic Container Fill-Height Inspection Machine.” There’s no Abstract for either, though they’re described this way in the application:

This invention relates to inspection apparatus of the type used to deter-mine whether a transparent container, such as a bottle, has been filled to the proper height with a liquid, and, more particularly, to improvements therein.

The requirement that the volume of beverage in a bottle correspond to the volume specified on the label on the bottle is a legal one. Good customer relations also provide more incentive to a bottler of liquids which require him to make sure that the contents of the bottle are as specified. On the other hand, should more than the specified amount of liquid be poured into the bottles, the bottler suffers an economic loss. Thus, a number of different systems have been proposed which inspect translucent containers, such as bottles, to determine whether the fill-height of the bottle is proper. These systems usually apply radiation on one side of the bottle and a detector on the other side of the bottle in the region of the bottle wherein desired fill-height occurs. However, due to various factors, such as the differences in bottle thickness, bottle color, variations in beverage color, as well as the presence of foam in many beverages, none of the heretofore-produced systems have proven consistently satisfactory.

An object of this invention is to provide a fill-height inspection system which is not adversely aifected by variations in bottle thickness or color.

Another object of this invention is the provision of a fill-height inspection system which is not adversely affected by differences in beverage color or the presence of foam.

Yet another object of the present invention is the provision of a novel and unique fill-height inspection system.

These and other objects of the invention are achieved by taking advantage of the fact that light is refracted or bent at ‘a unique angle by the liquid and its container. Thus, if a photocell is positioned on one side of a container so that no illumination from a light source can reach that photocell, unless it is refracted by the liquid in the container, a positive arrangement for detecting the fill-height of the liquid in the container may be obtained. The photocell is positioned adjacent the container at a level just below the minimum acceptable level. Similarly, to determine whether a container has been overfilled, a photocell may be positioned adjacent the container just above the maximum desired fill-height level, to be illuminated only by light which is refracted by the liquid in the bottle.

This invention relates to automatic fill-height inspection machines and, more particularly, to an improved arrangement for determining that a translucent container has been filled to the proper level.

Presently known automatic fill-height machines for photoelectrically inspecting a translucent container are not completely reliable, as a result of difficulties experienced with different colored bottles or bottles of varying opacity, thickness, or even in view of the fact that some liquids which are carbonated, such as beer, will have a foam at the top of the liquid which can provide a false signal as to the actual level to which the container is filled. Another difficulty which arises is that the prior systems are substantially limited to use with only one size of a container. If a production run of a different container size or even different fill-height requirements is desired, a considerable realignment of the fill height inspection apparatus parameters is required. A further limitation of prior systems is that they may be applicable only to translucent liquids.

An object of this invention is the provision of a reliable fill-height inspection apparatus.

Another object of this invention is the provision of a novel and useful fill-height inspection apparatus.

Yet another object of this invention is the provision of a fill height inspection apparatus which is easily adjustable for inspecting containers of different sizes.

Yet another object of this invention is to provide fill height inspection capability for opaque liquids, translucent liquids with foam on top, or solid (e.g., granular or powdered) materials in translucent containers.

Patent No. 430526A: Bottle Filling Machine

patent-logo
Today in 1890, US Patent 430526 A was issued, an invention of Joseph J. De Kinder and Hermann Roemer, for their “Bottle Filling Machine.” There’s no Abstract, though it’s described this way in the application:

Our invention relates to bottle-filling machines; and it consists of certain improvements, which are fully set forth in the following specification, and shown in the accompanying drawings, which form a part thereof.

While our invention relates to bottle-filling machines in general, it is especially adapted to beer-bottling, in which heretofore great difficulty has been experienced by reason of the great tendency of the beer to foam and of the difficulty of accomplishing the proper feeding of the beer from the barrel and of the loss of carbonic acid by exposure to the atmosphere. It is the object of our invention to overcome these difficulties and to accomplish a regular feeding of the liquid from the reservoir or supply without objectionable foaming in the bottles 0r Overflowing of the liquid.

In carrying out our invention we employ a convenient receptacle or vessel provided With delivery-tubes for delivering the liquid to the bottles, and connect this vessel with the barrel or supply-reservoir, and by means of certain devices, hereinafter more fully described, control the flow of the liquor from the barrel or reservoir by the level of the liquor in the delivery-vessel. By this means the supply of liquor in the delivery-vessel is replenished from the reservoir as the liquor is allowed to flow into the bottles Without the possibility of overflowing, for the moment the liquor in the delivery-vessel reaches a certain height the flowing of the liquor from the reservoir is automatically stopped and cannot begin again until the liquor-level has again fallen. This We accomplish by controlling the supply of air to the barrel or reservoir, as is hereinafter more fully described.

Patent No. 2039345A: Screw-Top Bottle Mouth

patent-logo
Today in 1936, US Patent 2039345 A was issued, an invention of Edward A. Ravenscroft, for his “Screw-Top Bottle Mouth.” There’s no Abstract, although in the description it includes this summary:

This invention relates to bottle mouths capable of being closed by drawn or molded caps of practical depths ‘and diameters. It resides in a formation of mouth which provides for a pouring lip without materially reducing the area of the throat or increasing the diameter of the required cap, and without necessitating a lowering of fastening means on the neck to such a point that drawn or molded caps .of impractical depths are required for closing.

In forming closures for bottles substantial economies may be erected through the use of cap closures instead of corks. The cap closure is ideal for bottles intended to contain dry or semi-dry substances, but for closing bottles intended to contain liquids, which are to be dispensed therefrom, cap closures known prior to this invention are open to very serious objections. The common screw cap closure is entirely devoid of any pouring lip and the stream emitted from such a bottle mouth breaks during pouring, spreads down the side of the bottle and is so erratic in behavior that it cannot be directed with any degree of certainty. The fluid which flows down the side of the bottle spreads in copious quantities into the threads or other fastening means on the neck and in many cases causes sticking of the cap. In the case of corrosive or poisonous fluids, the fluid on the outside of the bottle constitutes a real hazard; and in any case is decidedly disagreeable.

Attempts have been made to remedy the above difficulties but none of them has been acceptable. One of these attempts proposes the forming of a pouring lip at the top of the bottle, the threads for securing the cap being displaced a relatively long distance down the neck. This necessitates an exceptionally deep cap, which is so expensive to draw that any economy over the use of ordinary corks is impossible. Further, a substantial constriction of the throat of the bottle is involved in this construction which interferes with rapid pouring. In other constructions proposed a notch at the neck of the bottle is employed, the same producing a malformed lip of small effectiveness in producing a good stream and a clean cut-off. In this form the fastening means are placed entirely below the notch and here also a cap of excessive depth is required. In this form a very substantial constriction in the throat also is involved prior to this invention no means of eliminating the same has been proposed.

According to this invention, however, a good pouring lip is provided without constricting the throat to a substantial degree, the same being that the pouring stream is kept thin and in the accomplished without requiring a lowering of the fastening means on the outside of the neck. With the mouth of this invention a cap of ordinary depth may be employed, the same being substantially no deeper nor more expensive than 5 caps used with ordinary closures. There is also provided in this invention a crest concentric with the exterior of the neck so that a gasket in the cap will repeatedly seat to form a good seal.
