METHOD AND APPARATUS FOR OPENING OF CONTAINERS

摘要

A method and opener for creating openings in the sidewalls of bead seam containers, such as a pop-top can, to allow air to enter the container when the contents are poured is formed to include a mounting body (140). A seam engagement element (150) sized and shaped to fit the bead seam of a container and a piercing element (152) sufficient to pierce the sidewall of the container are positioned a predetermined distance from each other and in physical association with the mounting body (140) to pierce above the fill level of the container. The bead seam of a container may be inserted into the engagement element (150) creating a fulcrum, then rotated to engage the piercing element (152) to form an opening for air to enter the container when it is poured. These means may be mounted for stationary use (134) or have a handle attached (102) for portability. The portable opener with handle (102) extends a lever body from the mounting body (150) and is operated by placing the engagement element (150) on the bead seam of the container and rotating the handle (106) about the created fulcrum to engage the piercing element (152). These means have been integrated with examples of known bottle openers and tab lifters (20) creating an opener that is capable of lifting pop-top can tabs, opening bottles, and creating openings in the sidewalls of pop-top cans.

1. A method for piercing the sidewall of a container with a bead seam comprising of:
providing said container with a bead seam and providing an opener with an elongated body and an engaging device for engaging the bead seam of said container to create a fulcrum and a piercing device for piercing the sidewall of said container;
providing said engaging device and said piercing device are proximal and spaced sufficiently to allow said opener when rotated about said fulcrum to pierce the sidewall of said container; rotating said opener about said fulcrum in a manner that engages the piercing device to pierce the sidewall of said container creating a ventilation opening, reversing the rotation of said beverage key orients the engagement device to be disengaged;
providing said container has a pouring opening already incorporated the location of said ventilation opening is approximately located on the opposite side of the container as said pouring opening; andproviding said container does not incorporate any means for pouring a plurality of openings may be created in the sidewall of said for pouring or ventilating; providing the level of the contents of said container can are below said opening said container may remain upright without spilling the contents; whereby said container has said opening to allow air to enter said container from a separate opening than the one used for pouring.
