![]() ![]() The tool of our invention is illustrated in this lid opening position in Figures 2 and 4. A prying force is then exerted to lift the lid from its seat. To open such a can, the tip of a thin nosed tool must be inserted between lip 20: of lid i6 and the inclined portion 22 of the top of the can, with the tool body engaging edge,v M of the can. The lid then fits so tightly that it is impossible to remove the lid with ordinary openers without serious distortion of the lid. This usually occurs after use when some of the contents have collected on the sealing surface and reacted with air or moisture to corrode the metal, or when the moisture in the air rusts the metal: surface itself. This mutilation of the lid is particularly noticeable when the friction has been increased by corrosion and encrustation about'the seal. In the process of removing the lid, usually made from relatively thin sheet metal, this localized lifting force tends to bend the lid as the friction is overcome. The friction fit is usually fairly tight in order to obtain a satisfactory seal. The tool ordinarily used to remove the lid is a small nosed instrument, such as a screw driver, localizing the opening force applied to the lid. It is a common occurrence while opening cans of this type that the lid is bent and mutilated, and is often rendered unfit for further use. of shoe-polish tins, by gripping and rotating B67B7/14- Hand- or power-operated devices for opening closed containers for removing tightly-fitting lids or covers, e.g.B67B7/00- Hand- or power-operated devices for opening closed containers.B67B- APPLYING CLOSURE MEMBERS TO BOTTLES JARS, OR SIMILAR CONTAINERS OPENING CLOSED CONTAINERS.B67- OPENING, CLOSING OR CLEANING BOTTLES, JARS OR SIMILAR CONTAINERS LIQUID HANDLING.238000002360 preparation method Methods 0.000 description 2.238000004806 packaging method and process Methods 0.000 description 2.238000006011 modification reaction Methods 0.000 description 2.239000008187 granular material Substances 0.000 description 2. ![]() 238000004519 manufacturing process Methods 0.000 description 6.Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)
