ABSTRACT:
A knife guide device for the opening of the paper cartons in general use for milk and other liquids. It is designed to work well with any sharp knife, and it works equally well right or left handed. It leaves a clean cut spout for pouring or drinking, and it does away with the heavy laminated paper flange sealing that part of the carton and with most of the fuzzy coat of the broken seal that remains when it is torn open with the fingers as originally intended. It makes subsequent openings and closings of the spout much easier and neater. The knife guide device comprises a guide surface with a slot that fits over and around the sealed flange of the container to be opened, a tang that hooks underneath the not to be cut end of the flange, and a handle with two gauge notches to indicate the exact point for the vertical cut to be made before applying the guide blade to make the horizontal cut of the paper flange. The device will accomodate all paper containers of the above mentioned kind from the half gallon size and smaller. It is safe to use as all cutting is done away from the operator.
