Substrate container equipped with stabilizing support and smooth tray connection
The invention discloses a substrate container which includes at least one support for substrates. The support has plural ribs distantly separated with each other. The ribs define multiple slots and a carrying plane for receiving a substrate. Each of the ribs has a front end and a rear end. Rear ends of two neighboring ones of the ribs are connected by a closing portion, so that the rear end of a slot defined by the two neighboring ones of the ribs is closed. The closing portion has a concave surface. The concave surface and the carrying plane define a clamping position for substrate confinement.
1 . A substrate container, comprising:
a casing having a sidewall; and
at least one support connected to the sidewall of the casing and having a plurality of ribs spaced apart from each other, and the plurality of ribs defining a plurality of slots and a carrying plane for receiving a substrate;
wherein the plurality of ribs each has a front end and a rear end, and the rear ends of every adjacent two of the ribs are connected by a closing portion to allow the slots defined by every adjacent two of the ribs to be closed at the rear ends, the closing portion has a concave surface, and a clamping position for restraining the substrate is defined between the concave surface and the carrying plane;
wherein the concave surface at the rear end of the rib and carrying plane are configured to provide a clamping position to hold the substrate, and when the substrate is held at the clamping position, an upper edge of the substrate is restrained by the concave surface while a bottom of the substrate is supported by the carrying plane.
2 . The substrate container of claim 1 , wherein the clamping position allows the concave surface to restrain upper and lower surfaces of a substrate, and the carrying plane supports a bottom of the substrate, allowing the substrate to be held in place.
3 . The substrate container of claim 1 , wherein the concave surface is defined by a first slope and a second slope which are linked, wherein the first slope and the second slope define a concave included angle.
4 . The substrate container of claim 3 , wherein the two adjacent ribs are an upper rib and a lower rib, wherein bottoms of the upper ribs, tops of the lower ribs and the concave surfaces define the slots.
5 . The substrate container of claim 4 , wherein the bottom of the upper rib has a guide slope, and the guide slope is linked to the first slope of the concave surface of the closing portion.
6 . The substrate container of claim 4 , wherein the top of the lower rib has a descending slope, and the descending slope connects to the second slope of the concave surface of the closing portion, the descending slope and the second slope define a sink that is below the carrying plane.
