Container and packing method

Abstract

A container (1) is provided with: a container main body (3) for accommodating a plurality of optical elements (2); a lid body (4) for covering the container main body (3); and a compression pack (5) for compressing the container main body (3) and the lid body (4). A top plate section (12) of the lid body (4) is deformed in a convex shape while in contact with upper end sections (2a) of all of the optical elements (2) accommodated in the container main body (3) as a result of the lid body (4) and the container main body (3) being compressed by the compression pack (5) in a state in which the lid body (4) is disposed so as to cover the container main body (3), and the top plate section further presses the upper end sections (2a) of the optical elements (2) by utilizing the tension caused by such convex deformation. The container main body (3) and / or the lid body (4) of the container (1) is provided with a regulating unit for regulating the degree of the convex deformation in the top plate section (12) of the lid body (4).

Description

technical field [0001] The present invention relates to a container for accommodating optical elements including, for example, rectangular plate glass, and a method for packaging optical elements using the container. Background technique [0002] For example, a cover glass used in an image sensor of a digital camera is an optical element obtained by forming an optical filter such as an infrared cut filter on the surface of a plate glass by vacuum deposition or the like. As such an optical element, a very small rectangular optical element is used in order to be incorporated in an optical device such as a digital camera. In order to manufacture such an optical element, a method is generally employed in which an optical filter is deposited on the surface of a large plate glass, and then the plate glass is cut into small rectangles. The optical element thus obtained is packaged and stored in a predetermined container until it is assembled in an optical device, or shipped in a s...

Problems solved by technology

[0008] However, if the protective sheet is used in an unconstrained state as described above, the protective sheet may come into contact with the effective surface of the optical element and cause damage or contamination to the optical element depending on the degree of spacing between the optical elements.
