Patent number: 11771022Abstract: An assembly of fluid conduit parts is disclosed along with a method of assembling, a method of manufacturing and an apparatus for manufacturing the one of the fluid conduit parts. The assembly includes a blow molded part having a first portion. A second part includes a tapered section and a sealing flange extends from the first portion towards a central axis of the first portion at a distance, an end of the sealing flange defines an opening. The second part inserts into the opening and at least part of the tapered section is of a size larger than the opening. The sealing flange flexes upon insertion of the second part into the opening to define a contact surface between the tapered section and the sealing flange that extends around a perimeter of the tapered section where the sealing flange contacts the tapered section.Type: GrantFiled: November 3, 2022Date of Patent: October 3, 2023Assignee: Custom-Pak, Inc.Inventors: Ronald A.

Patent number: 8899416Abstract: An insert for protecting articles to be stored in a protective case. The insert is generally hollow and formed of a flexible thermoplastic material. The insert may be formed by a blow-molding process. The insert is shaped to fit within a protective case, which is also often formed by a blow-molded process. The material used to form the insert is less dense than that of the material used to form the protective case, and therefore the insert material is less stiff, softer, and more flexible.Type: GrantFiled: March 28, 2008Date of Patent: December 2, 2014Assignee: Custom-Pak, Inc.Inventors: Andrew James McDonnough, Duane David Franzen, Jr., Michael Grinnall

Publication number: 20080111285Abstract: A method and apparatus for blow molding a case for housing an object, such as a tool, is disclosed generally comprising first and second mold portions located adjacent each other to create separate cavities for forming base and lid portions of a case and a punch for each portion corresponding to the outline of an object. In certain embodiments, the punch protrudes into the cavity during blow molding to create a sidewall to facilitate a press fit. In some embodiments, additional punches and/or recesses are provided to produce additional apertures or flanges in the walls of the tool case.Type: ApplicationFiled: January 18, 2008Publication date: May 15, 2008Inventors: Clay Bahnsen, Michael Grinnall, Daniel Koranda, James Wiese

Publication number: 20070082153Abstract: A system for making blow molded receptacles is disclosed generally comprising two mold portions that, when positioned adjacent each other, at least partially enclose a cavity defined by a molding surface, against which the walls of a blow molded receptacle are blown. One of the portions is a mold core, which has a base surface and a raised portion extending out from the base surface into the cavity. The raised portion has an outer surface and a side surface, which results in a corresponding, inner sidewall on the blow-molded receptacle. The raised portion houses a punch partly disposed in an opening in the side surface for punching a hole in the sidewall. In some embodiments, the side surface is substantially perpendicular to the seal between the two mold portions, and an actuator displaces the punch in a direction substantially parallel to the seam.Type: ApplicationFiled: October 7, 2005Publication date: April 12, 2007Inventors: Alan Knapper, Daniel Koranda, Michael Grinnall

Patent number: 7182905Abstract: A blow molded article includes an outer wall and an article retaining feature projecting outwardly therefrom. The article retaining feature includes a distal wall and a side wall connecting the distal wall and the outer wall of the blow molded article. The side wall is generally orthogonal to the outer wall of the blow molded article, and an inner surface is defined at least partially by inner edges of the side wall, the distal wall and the outer wall of the blow molded article. The side wall has a hole integrally molded therein.Type: GrantFiled: October 21, 2005Date of Patent: February 27, 2007Assignee: Custom-Pak, IncInventors: Michael Grinnall, Duane Franzen, Terry Lucky

Publication number: 20070012704Abstract: A blow molded case is disclosed generally comprising a double wall, blow molded base portion having inner and outer case walls, and a lid portion connected to the base portion such that the lid, when in a closed position, at least partly covers the inner case wall of the base portion, which accommodates a first object. The outer wall of the base portion has a hole for receiving a second object, such as a drawer or other receptacle. In certain embodiments, the hole is a punched hole, created by extending a punch through a sidewall of the base portion substantially perpendicular to the parting line thereof. In certain embodiments, the sidewall is non-planar, and in some embodiments, the sidewall includes a recess adjacent the hole for easily gripping the second object.Type: ApplicationFiled: July 13, 2005Publication date: January 18, 2007Inventors: Michael Grinnall, David Cozzens, Clay Bahnsen, Steven Guidebeck, James Wiese

Publication number: 20060228943Abstract: A core side of a mold includes a mold surface against which the article bears during molding, a core pull and an ejector pin. The core pull includes a protuberance moveable between an extended position in which the protuberance protrudes beyond the mold surface, and a retracted position in which the protuberance does not substantially protrude beyond the mold surface. The ejector pin includes an end moveable between an extended position in which the end protrudes beyond the mold surface, and a retracted position in which the end does not substantially protrude beyond the mold surface. The protuberance is in the extended position and the ejector pin end is in the retracted position during a part retaining portion of a mold cycle, while the protuberance is in the retracted position and the ejector pin end is in the extended position during a part ejecting portion of the mold cycle.Type: ApplicationFiled: April 11, 2006Publication date: October 12, 2006Inventor: Michael Grinnall
