BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present Invention Patent is intended to make known a new device provided with advantageous features for the opening of certain types of preserve cans, tins and similar containers.
As it is known, one of the traditionally-known types of preserve cans features a tear-off upper lid provided with a ring which is to be held with one hand in order to perform such function. However, given the tearing resistance which is sometimes shown by the lid, a certain rough action is required to open the can which involves a certain risk of small wounds on the user's hand, the projection of the contents out of the can, etc.
The present Invention Patent is intended to overcome the above drawbacks by providing the means required to carry out the opening of such type of closing device in preserve cans in a very simple and practical way.
SUMMARY OF THE INVENTION
Essentially the present invention patent consists of a curved-type plate intended to lean against the lid to be opened with such plate being provided with a preferably-bent long upper arm and an end hook which is to be coupled to the lid ring thus allowing for a tilting motion of the curved plate when the ring is pulled by the hook thus ensuring an easy, controlled opening of the lid. Given the lever effect caused by the upper arm of the device, it is possible to easily adjust the force to be manually exerted in order to accomplish a smooth, well-controlled opening of the can.
For the sake of a better understanding, a number of drawings which are explanatory but not limited to this device are enclosed as an example.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a perspective view of the device.
FIGS. 2, 3 and 4 each are elevation views from different planes of the device itself.
FIGS. 5 and 6 each are representative views of the device application.
FIG. 7 is a perspective view of the opener which shows the area intended for opening crown caps.
FIG. 8 is a perspective view of the opener which shows the device handle.
FIG. 9 is a side elevation view with FIGS. 10 and 11 corresponding to an end elevation view and a plan view of such opener, respectively.
FIGS. 12, 13 and 14 each are views of a sheet shim or similar component which remains embedded in the material of the opener intended to permit the opening of crown caps and the removal of pressed-mounted lids.
FIG. 15 shows a detailed section of the coupling of the sheet piece of the opener body.
FIGS. 16 and 17 show the application of the opener to cans or tins provided with opening rings and expiration lines.
FIGS. 18 and 19 each are elevational views of the application of the opener press inserted lids.
FIGS. 20 and 21 show the opener place on a crown cap opening.
DESCRIPTION OF THE BEST MODES FOR CARRYING OUT THE INVENTION
As shown in the drawings, this device is composed of a main element (1) in the shape of a curved plate or body which is coupled to a long lever or arm (2) which is also either curved or straight, preferably with the concavity in opposite direction to item (1). A hook (3) is coupled to such lever on the end adjacent to the coupling with plate (1) which is intended to be coupled to the ring of the can or container to be opened. The exact shape of plate (1) and lever (2) will vary since the basic structure is characterized by the curved shape of element (1) and the presence of lever (2) intended to multiply the manual opening effort. Likewise it is obvious that the arrangement of hook (3) is essential to the features of this Patent.
As shown in figures enclosed, the device is applied in such way that the plate or sheet body (1) remains laid on the can or container to be opened (4), see FIGS. 5 and 6, with hook (3) coupled to ring (5) of such can. When an effort is exerted on the lever arm (2) which is represented by vertical vector (6), curved plate (1) performs a rolling movement over the lid (7) of the container (4) while ring (5) is pulled by hook (3) thus carrying out the removal of lid (7) from can (4) by tearing it off, i.e. by trying to open it.
