As shown in
FIGS. 1A & 1B
, the can, which is often made of tin, generally includes a can body
2
,
2
′ having an operating top rim
21
,
21
′ and a central top opening to be covered in an air-tight manner by a cover
1
having an operating top flange
11
for storing therein powdered milk, biscuit, cracker . . . or the like. Since top flange
11
is small and held extremely adjacent to can body
2
,
2
′, it is always necessary to open the can with screwdriver, spoon, a pair of scissors . . . or the like which is, however, dangerous and/or inconvenient to the user troubled to find it out from somewhere. Certainly, it can be found there also is someone who is unwilling to be so troubled and thus does not want to airtightly utilize cover
1
which, certainly, is not a good way to use the can.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a can opener. It is therefore another object of the present invention to provide a safe and/or convenient can opener.
According to the present invention, a can opener adapted to be used with a can having an operating rim and an opening to be covered in an air-tight manner by a cover having an operating flange includes an operating medium for being operated against the operating flange to open the can covered in the air-tight manner by the cover, and an attaching medium secured to the can for always attaching thereto the operating medium in a position ready for opening the can.
Certainly, the operating rim integrally forms thereto a top flange, the attaching medium can be secured to the can by means of welding, clipping, magnet or adhesive, the rim can form a fulcrum for the operating medium, the attaching medium can be a flat plate, and the operating medium can be a bent strip, in which there is a distance between the rim and a point where the operating medium is bent.
Preferably the present can opener further includes an elastic member mounted between the operating medium and the can for always urging the operating medium in the ready position, in which the elastic member can be spring or elastic plate.
Preferably the operating medium has a lug, and the attaching medium has a retainer for retaining therein the lug, and the retainer preferably pivotally retains therein the lug. Alternatively, the retainer can be a spirally coiled end extended from the attaching medium.
Preferably the operating medium has another lug and the attaching medium has another retainer for retaining therein the another lug. Alternatively the attaching medium can have an upper opening and the operating medium can have a side lug for preventing the operating medium from escaping from the attaching medium.
Alternatively the attaching medium can have a holed upper portion to be elastic, and the operating medium can have a lug extension for deforming the upper portion when operated to open the can.
Certainly the attaching medium can have a bent extension for engaging with the rim.
According to another aspect of the present invention, a can opener used with a can having an operating rim and an opening to be covered in an air-tight manner by a cover having an operating flange includes an operating medium for being operated against the operating flange to open the can covered in the air-tight manner by the cover, an attaching medium secured to the can for always attaching thereto the operating medium, and an elastic member mounted between the operating medium and the can for urging the operating medium in a position ready for opening the can.
