The present invention relates to a hitch step that may be secured to a vehicle in a hitch receiver, and a method of manufacturing the same, that overcomes the disadvantages of the prior art. The present invention provides a multi-step pressurization method that produces a strong, compact hitch step that is cost effect to manufacture.

A drapery carrier installation system includes carriers, each having a carrier body and to engage with a track for hanging drapery; an installation rack for holding the carriers relative to one another prior to installation, the installation rack having protrusions for engaging with the carriers; the carriers are secured above the top surface of the installation rack; and the installation rack is removed via a downward or sideways force applied to the installation rack, thereby releasing the installation rack from each of the carriers.

This nest comprises a plurality of breakable connecting bridges, a plurality of flanges arranged in a predetermined pattern and configured to form the flanges of the medical containers, the flanges being connected to the breakable connecting bridges, and a supporting structure attached to the breakable connecting bridges so as to support the flanges. The flanges are integrally formed with the breakable connecting bridges and the supporting structure.

A spacer (1) is injection molded by using an injection molding die having resin flow channels that are designed such that a plurality of gates (6) are arranged along the longitudinal direction at a position corresponding to the outer peripheral surface of a side wall part (4) in which a plurality of arc-like peripheral surface parts (2) are connected through a waist part (3). After opening the mold and ejecting the spacer, the spacer is cooled with a runner (7) being connected to the gate (6), and thereafter, the runner (7) is cut off. As a result, when producing a water jacket spacer that is assembled to the inside of the water jacket and controls the flow of cooling water by injection molding, while producing with a high productivity without being affected by design constraints caused by draft angle, deformation in the post-molding cooling step is prevented.
