Abstract
Abstract In this method of packing electronic parts electronic parts are inserted into a plurality of containers each of which has an opening on the upper surface thereof. These containers are juxtaposed side by side. A single common pressing plate is disposed over the containers so as to cover their openings. The containers and pressing plate are packed together in a sack under vacuum.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
317 words
A method capable of packing under vacuum electronic parts having variations in thickness, the method comprising the steps of: inserting said electronic parts into a hollow elongated electronic parts container, said hollow electronic parts container having an opening on the upper surface thereof and an inner space where said electronic parts are housed in a row along the longitudinal direction of the container, said opening being formed along the longitudinal direction of the container, and said inner space having a size allowing said electronic parts within the container to freely move along the longitudinal direction of the container; juxtaposing a plurality of said electronic parts containers side by side; disposing a single common pressing plate of flexible material over said plurality of electronic parts containers so as to cover said openings on said upper surfaces and for pressing against the electronic parts in the containers, whrein said pressing plate has integrally formed projections thereon with the same number of rows of projections as said plurality of electronic parts containers, each of said projection rows having a plurality of said projections and facing one of said openings of each of said containers, each of said projections being elongated in the longitudinal direction of each of said containers, and wherein the width of said pressing plate is less than that of each of said containers; and packing said electronic parts containers and said pressing plate together in a sack under vacuum, wherein each of said electronic parts housed in said containers is pressed by at least one of said projections under the action of vacuum and wherein said pressing plate comprises flat portions between said projections in each projection row and between said projection rows so that the pressing plate can freely deform under vacuum action so that all of said electronic parts can be firmly pressed and held stationary even with variations in thickness of said electronic parts.
