Patent number: 8025825Abstract: A method for the compression molding of a plastic part including a neck which is equipped with an orifice, in which a blank is created and compressed. The part is molded with a neck which is equipped with a top wall including a thin area with a notch, the contour of this thin area defining the orifice, and two zones which can withstand the mechanical stress necessary in order to break the top wall at the notch. One of the two zones is intended to transmit the mechanical stress and the other is used as a support. The section of the notch is slightly inclined in relation to the axis of the neck. After molding, mechanical stress is applied to one part of the top wall, other than the thin area, so that the top wall tears at the notch, thereby producing the dispensing orifice.Type: GrantFiled: March 17, 2003Date of Patent: September 27, 2011Assignee: Cebal SASInventors: Bertrand Gruau, Herve Zakrzewski

Patent number: 7687004Abstract: A process is disclosed for making a closure having (i) a top portion, and (ii) a latch member that includes an actuator portion and a follower portion, the follower portion including a blocking structure. The process includes providing a mold assembly that defines a space therein which corresponds to the closure, the mold assembly including (i) a first mold portion that defines a first subspace which corresponds to the actuator portion, and (ii) a second mold portion that defines a second subspace which corresponds to the blocking structure. The process further includes advancing a material into the space so as to form the closure. The process also includes moving the second mold portion in relation to the first mold portion after the advancing step so as to remove the actuator portion from the first subspace.Type: GrantFiled: May 16, 2007Date of Patent: March 30, 2010Assignee: Allen Tool Company, Inc.Inventor: David O. Allen

Patent number: 7676854Abstract: This invention relates to a helmet, comprising an external shell (9) and an impact-absorbing helmet liner (10) in which the helmet liner comprises a layer provided with protruding, deformable and impact-absorbing hollow knobs (7) distributed on an substantial part of the surface of the helmet liner as a protective layer. The helmet is characterized in that the hollow knots (7) are arranged for deformation by crushing in case of external impact on the helmet, and that the helmet liner (10) with the hollow knots (7) exhibits undercut. The helmet may also comprise an impact-absorbing and preferably resilient layer (2) which may be arranged between the external shell (9) and an internal lining (11) being arranged to rest in contact with the head of a user.Type: GrantFiled: April 7, 2005Date of Patent: March 16, 2010Assignee: Crescendo ASInventors: Jan Gisle Berger, Johan Horsrud, Ulf Tolfsen, Roy Kristiansen

Patent number: 7661942Abstract: The present invention provides for an improved device for molding keyhole sipes larger in size, i.e. sipes having a wider passage, than currently being formed in treads that will avoid damaging the tread during formation and removal thereof from a mold. The device includes an elongated deformable body member having a blade extending in a direction away therefrom and substantially along the length thereof. The body member also includes a stiffening member securely fixed in position therein that extends substantially the length thereof. The stiffening member provides a desired rigidity to the deformable body member, thereby limiting flexion along its length under the stress of a rubber formulation when the mold is closed during the molding process. Also, the deformable body member provides low stress on the tread when a slit of the keyhole sipe is pulled around the body member during removal of the tread from a mold.Type: GrantFiled: July 21, 2005Date of Patent: February 16, 2010Assignee: The Goodyear Tire & Rubber CompanyInventors: Gia-Van Nguyen, Alain Francois Emile Roesgen, Anne-France Gabrielle Jeanne-Marie Cambron

Patent number: 7661203Abstract: A loading basket (6) for a washing machine (1) comprises a rear wall (8), a front wall (9) opposite the rear wall (8) and a side wall (7) defining an inner space (10) of the basket, as well as one or more dragging blades (12) arranged on the side wall (7) and projecting to the inside of the basket. The side wall (7) comprises a drilling with a plurality of small through holes (13), which are arranged at the vertex of respective domes (14) projecting to the outside of the basket (6), as well as a plurality of rounded projections (18) in the shape of a spherical dome without through holes and projecting to the inside (10) of the basket (6).Type: GrantFiled: June 20, 2007Date of Patent: February 16, 2010Assignee: Candy S.p.A.Inventor: Silvano Fumagalli

Publication number: 20090308833Abstract: An opening device for a packaging container comprises a neck portion and a screw cap. The opening device comprises a wall of the first part of the screw cap being with a weakening extending in a circumferential direction of the first part and a recess extending in a longitudinal centre axis direction of the first part. The recess is arranged to receive a projection of the neck portion, which projection is directly injection-moulded in the recess. A tamper flap of the first part, which tamper flap is defined by the weakening and the recess, is automatically deformable in connection with a first time opening of the packaging container by cap rotation.Type: ApplicationFiled: June 28, 2007Publication date: December 17, 2009Applicant: Tetra Laval Holdings & Finance S.A.Inventors: Pär Andersson, Patrik Månsson, Cristiano Casale

Patent number: 7632447Abstract: An arch shape cross section thermoplastic leaching chamber, having sidewall slot perforations which flare inwardly, is made using a mold comprised of a mold cavity part and an inwardly retractable mold core part. The core part has opposing side slides with projections that define the perforations; they are separated by a center block. The center block moves downwardly and the slides move inwardly, under action of slide rods built into the mold core, to enable a molded chamber to be removed from the mold.Type: GrantFiled: November 29, 2005Date of Patent: December 15, 2009Assignee: Infiltrator Systems, Inc.Inventors: Daniel J.

Publication number: 20090290986Abstract: An impeller of a blower is disposed with circular support plates that are made of a resin and rotate about an axis of rotation and a plurality of blades that are made of a resin. The blades are disposed on outer peripheral portions of the circular support plates so as to be parallel to an axis of rotation, and serrated shapes are formed on the blades by cutting out blade tips at plural places. Additionally, a step is formed in a blade face of each of the blades at a position a predetermined distance from the blade tip where the serrated shape is formed.Type: ApplicationFiled: September 26, 2006Publication date: November 26, 2009Applicant: DAIKIN INDUSTRIES, LTD.Inventors: Kazuya Haraguchi, Yoshinori Kagawa, Hideshi Tanaka, Kouzou Yoshinaga
