Patent No. 3037431A: Carton Feeding, Erecting And Filling Mechanism

Today in 1962, US Patent 3037431 A was issued, an invention of Leonard McGihon of San Leandro, California, assigned to the King-O-Matic Equipment Corp., for his “Carton Feeding, Erecting And Filling Mechanism” There’s no Abstract, although there’s a paragraph in the description that summarizes it nicely.

The present invention relates to mechanism for taking respective folded cartons, successively from a stack, opening these cartons to a box-like form with open sides, feeding cans or other containers in groups into the carton through the open sides thereof, and then closing the cartons so as to provide a carry-home pack of the containers in the carton. The various operations take place in sequence and continuously to provide a rapid and efficient method of packing containers in cartons, for example beer cans packed in the familiar six-pack cartons as now commonly on the market. More particularly, the instant mechanism is designed to operate on a carton of a character having a closed rectangular shape with partially open sides, the open sides being provided with connected or continuous side flap portions, the respective adjacent side flaps of each corner being connected by a gusset type fold. In this type of carton, the folding of the flaps attached to the end panels of the carton tucks these flaps behind the containers or cans in the carton and effectively holds the carton closed during shipment and handling, but provides for easy opening by the user.

Patent No. 784596A: Filling Apparatus For Liquids

Today in 1905, US Patent 784596 A was issued, an invention of Simon Schlangen, for his “Filling Apparatus for Liquids.” There’s no Abstract per se, but this is pretty close, from the introduction:

The invention relates more particularly to apparatus for filling barrels, kegs, and similar packages with liquid, such as beer, under pressure, and has for its objects to improve the suspending means by which the closing head and filling-tube are carried, so as to insure the proper contact of the closing-head with the bung-hole or filling-hole of the barrel, keg, or package, to insure the positive opening-of the valve controlling the discharge of the filling-tube when the filling-tube has reached the limit of its descent, to improve the construction and operation of the appliance carrying the closing-head and the filling tube in connection with a fluid-pressure cylinder having therein a piston by which the cross-heads carrying the closing-head and the filling-tube are raised and lowered, to utilize the waste pressure from the filling-package in actuating’ the piston by which the closing head and the filling-tube are raised and lowered, to place the control of the pressure and the liquid under a single valve, to improve the construction and operation of the valve by which the fiI’Iid-pressure and the liquid are controlled, to improve the means by which the inflow and outflow of the pressure between the filling-tank and the to be filled package is regulated and controlled, to prevent the foaming of the liquid within the package and insure the fillingI of the package with the liquid to its full capacity without waste of liquid, to furnish an intermediate controlling means for the pressure between the one controlling-valve and the to be filled package by which the flow of the pressure in either direction will be regulated and controlled, to furnish a relief-valve by means of which the requisite amount of pressure from outside will be supplied to prevent an explosion at the withdrawal of the filling-tube, and to improve generally the construction and operation of the several parts and mechanisms which enter into the “construction of the apparatus as a whole.

Today in 1933, US Patent 1899203 A was issued, an invention of Joseph Charle Auguste Labreche, for his “Combined Bottle Opener and Key Ring.” There’s no Abstract, but the simple description states that the “invention pertains to a novel combined bottle opener and key ring designed a to be carried conveniently-in the pocket.” Weird to think that this had to be patented, they seem so ubiquitous now.

Patent No. 2497870A: Container Closure

Today in 1950, US Patent 2497870 A was issued, an invention of Stanley W. Dennis, assigned to the Crown Cork & Seal Co., for his “Container Closure.” There’s no Abstract, but the description states that the “The present invention relates to closures.” Happily, they expound upon that somewhat:

More particularly, the closure of the present invention is an improvement on closures of the type shown, described and claimed in a number of prior patents to G. W. Booth, owned by the assignee of the present application, such as Patents 1,956,209, Reissue 19,422, 1,956,213, 1,956,214, 1,956,215 and 1,956,217. Certain features of the invention, however, as regards cap structures, have utility and may be used in connection with caps of other types, as will be apparent from the following description and the appended claims.


Patent No. D162082S: Combination Can And Bottle Opener

Today in 1951, US Patent D162082 S was issued, an invention of Carl G. Preis, for his “Combination Can and Bottle Opener.” There’s no Abstract, but the rather short application states simply that Preis has “invented a new, original, and ornamental Design for a Combination Can and Bottle Opener.”

Patent No. 20110036840A1: Ring Pull Can Cap

Today in 2011, US Patent 20110036840 A1 was issued, an invention of Tal Zakai, for his “Ring Pull Can Cap.” Here’s the Abstract:

The present innovation is a dual purpose “ring-pull/can cap”, which performs as both a sealing cap for metal beverage cans in addition to its traditional usage as a can opener. The design is a modification of the U.S. Pat. No. 3,967,752 “easy open wall”, which is the current opening mechanism on most consumer beverage cans, also known in the industry as an “easy open end”. The “ring-pull/can cap” is an improvement of the well known ring-pull design found on most metal cans today, but also allows consumers to close and seal off the can when not in use.

There are two popular opening methods that have been used for opening metal cans to date: The “full open” mechanism and the more recent “half open” mechanism, as described below. The present invention deals with the improvement of the popular “half open” method, which currently does not allow the beverage can to be resealed after opening.


Patent No. 2925237A: Can & Bottle Opener

Today in 1960, US Patent 2925237 A was issued, an invention of John L. Fox, for his “Can and Bottle Opener.” There’s no Abstract, but the application states that his ” invention relates to a can and bottle opener, and more particularly to a can and bottle opener which can be moved to an out-of-the-way position when it is not being used.

An object of the invention is to provide a can and bottle opener which includes a novel mounting means so that for example with the opener mounted beneath a kitchen cabinet or shelf, the device can be kept in an out-of-the-way position until it is being used, and wherein when the device is being used it can be readily moved to an operative position, and wherein the opener of the present invention is provided with a magnetic means.
