ABSTRACT:
The present invention relates to an opener for cutting open a packaging film of a CD, CD-ROM, VCD or DVD box or the like.
BACKGROUND OF THE INVENTION
A CD, CD-ROM, VCD or DVD disc is normally sold in a thin plastic box which is, in turn, usually wrapped by a packaging film. Experience tells that the tearing open of the packaging film may not be easy for a customer using bare hands, and a knife is sometimes needed.
The invention seeks to mitigate or to at least alleviate such a problem by providing an opener.
SUMMARY OF THE INVENTION
According to the invention, there is provided an opener for cutting open a packaging film of a box containing a CD, CD-ROM, VCD or DVD disc or the like, which opener comprises a body having a gap for receiving a part of a narrow side of a said box, a cutter provided in the body, and an operating member provided in the body for operation to move the cutter into the gap for cutting open the packaging film of said box with a narrow side thereof inserted into the gap, said operating member being associated with an actuator for operation, which is resiliently biased to be accessible in the gap.
Preferably, the operating member is supported for pivotal movement between a rest position in which the actuator is accessible in the gap and an operating position in which the cutter extends into the gap.
More preferably, a spring is provided in the body for resiliently biassing the operating member into the rest position.
For simple construction, the actuator is an integral part of the operating member.
For simple construction, the cutter is supported on the operating member.
It is preferred that the gap has a bottom side and the body is formed with two apertures at the bottom side of the gap, through which apertures the actuator and cutter are extendable into the gap.
In a preferred embodiment, the body is formed by two generally flat parts stacked together, each said body part having a principal wall and a continuous side wall including respective straight sections aligned with each other to form a bottom side of the gap.
More preferably, the body has a generally flat cylindrical shape.
