Abstract
A gas sampler device has a top plate with a concaved outer wall. The concaved outer wall allows users easily to lift the top plate off of the bottom plate without disturbing the bottom plate because the curved surface permits more positive contact between the outer wall and users' fingers. Moreover, the weight of the top plate is reduced by approximately twenty percent compared to conventional top plates, a feature that also makes it easier for users to lift the top plate off of the bottom plate.
Claims16
An ergonomic sampler device, comprising:
- a top plate including a top surface, a side wall with an inner surface and an outer surface, the inner surface of the top plate being straight, a plurality of through bores through the top surface of the top plate,
- a bottom plate including a top surface, a bottom surface, a side surface, and a receiving portion at the top surface of the bottom plate for receiving a dish,
- wherein the top plate is separable from the bottom plate, and the top surface of the bottom plate mating with the side wall of the top plate, the bottom surface of the bottom plate comprising
- a channel terminating at a hole in the side surface, the channel fluidly connecting the plurality of through holes of the top plate with the hole in the side surface of the bottom plate,
- wherein the outer surface of the top plate being concaved inward, a rounded lip between the top surface of the top plate and the side wall of the top plate,
- wherein the side wall has a sharp lip opposite the rounded lip, wherein each of the rounded and sharp lips extends outwardly beyond the outer surface,
- wherein the outer surface terminates at the rounded and sharp lips, respectively.
