Impact detector and packaging container
First Claim
1. An impact detector comprising:
- a case, an interior of which defines a first transition path and a second transition path;
an impact indicator disposed on a front side of the case, to indicate an impact history of the impact detector when the case falls to at least one of a first direction and a second direction opposite the first direction;
a first weight disposed inside the case, that moves to a side to which the case falls, causing the impact indicator to indicate the impact history by moving through at least one of the first transition path and the second transition path;
a first guide member to guide the first weight from an initial position to a first impact detection position along the first transition path when the case falls in the first direction; and
a second guide member to guide the first weight from the initial position to the second impact detection position along the second transition path when the case falls in the second direction;
wherein the first transition path at least partly overlaps with the second transition path on a projection plane on the front side of the case.

Abstract
An impact detector includes a case, an impact indicator disposed on a front side of the case, to indicate an impact history of the impact detector, a first weight that moves inside the case to a side to which the case falls, causing the impact indicator to indicate the impact history by moving through at least one of a first transition path and a second transition path, a first guide member to guide the first weight to a first impact detection position along the first transition path when the case falls in a first direction, and a second guide member to guide the first weight to the second impact detection position along the second transition path when the case falls in a second direction. The first transition path at least partly overlaps with the second transition path on a projection plane on the front side of the case.

20. An impact detector comprising:
-
a case, an interior of which defines a first transition path and a second transition path; an impact indicating means for indicating, on a front side of the case, an impact history of the impact detector when the case falls in at least one of a first direction and a second direction opposite the first direction; a first weight disposed inside the case, that moves to a side to which the case falls, causing the impact indicating means to indicate the impact history by moving through at least one of the first transition path and the second transition path; a first guide means for guiding the first weight from an initial position to a first impact detection position along the first transition path when the case falls in the first direction; and a second guide means for guiding the first weight from the initial position to the second impact detection position along the second transition path when the case falls in the second direction; wherein the first transition path at least partly overlaps with the second transition path on a projection plane on the front side of the case.
