Abstract

Abstract A disposable flashlight includes a battery and bulb within a casing, a conductive clip engaging the battery and extending through an elongated peripheral slot in the casing, and a conductive member engaging a terminal of the light and extending into proximity with the end of the clip so that the end of the clip can be pushed through a contact opening in the casing into electrical contact with the conductive member to turn the light on. The peripheral slot extends a sufficient distance along the circumference of the casing so that the clip can be rotated within the slot to an "off" position in which its end no longer overlies the contact opening within the casing. In that position, the light cannot be activated when pressure is applied to the clip.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 151 words
In a disposable flashlight having a battery and light within a casing, a conductive clip engaging the battery, and a conductive member engaging a terminal of the light and extending into proximity with the end of the clip so that the end of the clip can be pushed through a contact opening in the casing into electrical contact with said conductive member to turn on the light, the improvement comprising, a peripheral slot in the casing through which the clip extends, said slot extending a distance along the circumference of the casing such that the clip can be rotated to an "off" position where said clip end does not overlie said contact opening to thereby prevent the light from being energized by the application of pressure to said clip end, said slot further including a detent between its ends so as to retain the clip in its "off" and "on" positions.
Claim 2
Dependent Claim 151 words
In a disposable flashlight having a battery and light within a casing, a conductive clip engaging the battery, and a conductive member engaging a terminal of the light and extending into proximity with the end of the clip so that the end of the clip can be pushed through a contact opening in the casing into electrical contact with said conductive member to turn on the light, the improvement comprising, a peripheral slot in the casing through which the clip extends, said slot extending a distance along the circumference of the casing such that the clip can be rotated to an "off" position where said clip end does not overlie said contact opening to thereby prevent the light from being energized by the application of pressure to said clip end, said slot further including a detent between its ends so as to retain the clip in its "off" and "on" positions.
Claim 3
Dependent Claim 23 words
The improvement in a clip light according to either of claims 1, wherein the casing includes an on-off indicator marking adjacent said slot.
