Estimating the term…
The presser member (1) of the present invention is shaped from different materials for the contacting part (5) to press-hold the precision substrates (15) and for the parts excepting the said contacting part (5). The presser member (1) is shaped from a thermoplastic elastomer for a rectangular frame part, a contacting part (5) formed in a pair of structuring parts (4) provided in such a fashion as to inwardly extend from each of a pair of oppositely facing two sides and a second contacting part (11) formed in the extension peripheral part extending via a supporting part (10), the other parts being shaped from a thermoplastic resin. The aforementioned contacting part (5) is provided with grooves of a V-formed cross section with inclinations changed in the middle way for receiving the peripheries of precision substrates (15) and V-grooves for press-holding the peripheries of precision substrates are provided in the resilient pieces (12) separated and protruded in a comb teeth-like fashion to form the second contacting part (11).
A presser member in a container vessel for precision substrates which is a presser member for precision substrates attached to a container vessel for precision substrates consisting of a container vessel body for precision substrate having an opening at one end to contain precision substrates and a covering body engageable with the aforementioned container vessel body and is characterized in that the aforementioned presser member is shaped from different materials for a contacting part to press-hold the precision substrates and the parts excepting the contacting part:
A container vessel for precision substrates characterized in that a presser member, of which a contacting part coming into contact with the precision substrates is shaped from a thermoplastic elastomer and the parts excepting the aforementioned contacting part are shaped from a thermoplastic resin, is attached thereto.
