Abstract: In one aspect, the present invention is directed to a pacifier, comprising: a nipple; a protection cap; and a connection mechanism, for connecting the nipple to the cap, the connection mechanism comprise a springy element wherein in the idle state of the springy mechanism the nipple is entirely protected by the cap from contact with a plane, and in the non-idle state thereof the nipple outstands from the plane, thereby enabling being used by an infant. According to one embodiment the connection mechanism comprises: a cylinder; a sliding plug fitting closely inside the bore of the cylinder; a spring keeping the plug secured to an opening of the cylinder, the nipple being connected to the plug. The springy element may be based on a spring, bellows, an elastic object, and so forth.

Abstract: A toothbrush distal end for attachment to a handle of a mechanical toothbrush; the distal end comprising: a head; a neck having a proximal end and a distal end; a drive shaft having a driving bevelled gear fixed to distal end thereof; a brush consisting of a bristle array on a brush back plate, and a movement; the head being fixedly attached to the distal end of the neck; the neck being fixedly couplable to the handle and the drive shaft being couplable to a driving means; the neck being hollow and serving as a sleeve for the drive shaft; the drive shaft being rotatingly drivable about its axis within the neck, by the driving means; wherein the movement is situated within a cavity in the head and is connected to the brush back plate, for moving the brush back plate along an eccentric orbital path with respect to the head when driven by the driving means via the rotating drive shaft.
