Patent number: 8252224Abstract: Multi-layered drink-containers including an inner liquid-container and an outer shell in an at least partially overlapping, telescopic relation relative to the inner-liquid-container and methods of assembling the same. In some examples of multi-layered drink-containers, the inner liquid-container includes a lower portion having an outer cross-sectional area, an orthogonal projection of which at least partially overlaps an orthogonal projection of an inner cross-sectional area of an upper portion of the outer shell. Some examples of methods of assembling multi-layered drink-containers include reducing a resiliently deformable restrictive-portion of an inner liquid-container, positioning an outer shell in an at least partially overlapping, telescopic relation relative to the inner liquid-container, and returning the resiliently deformable restrictive-portion to a neutral, un-deformed and un-reduced state.Type: GrantFiled: May 13, 2009Date of Patent: August 28, 2012Assignee: CamelBak Products, LLCInventor: Christopher C.

Publication number: 20120207413Abstract: A container that includes a substantially rigid body having a neck defining an opening providing access to the body cavity, and a bag positioned in the interior of the body. The bag is formed of thermoplastic material and has a neck from which there radially extends a flange which rests on the body and which defines a hole for providing access to the cavity of the bag and for sealedly housing the body of a hermetic pump (P) operable manually to withdraw the fluid substance (F) from the bag and feed it to the outside through its dispensing stem (S). The bag is formed by hot blow-moulding a preform positioned directly on the inside of the container. The preform surface presents at least externally a plurality of microspheres which roughen its surface.Type: ApplicationFiled: February 5, 2012Publication date: August 16, 2012Applicant: Lumson S.p.A.Inventor: Matteo MORETTI

Publication number: 20120187067Abstract: A preform can be made from two different materials that do not bond together by a bi-injection process, using the same mold. An outer preform can be fashioned first, then an inner preform molded through a center hole in the outer preform's bottom. The preforms are then connected. Inner/outer preform materials can be different, e.g., PET/polyolefin or polyamide, or the same, e.g., PET/PET—if mutual bonding during the molding of the second is prevented. A non-stick coating can be sprayed on a surface portion of the first preform touching the second perform, then the second container molded. Manufacturing order can be either outer/inner, or inner/outer, and the non-stick coating sprayed on the inside/outside of the perform first molded, followed by molding of the other.Type: ApplicationFiled: December 19, 2011Publication date: July 26, 2012Applicant: Dispensing Technologies B.V.Inventors: Wilhelmus Johannes Joseph Maas, Petrus Lambertus Wilhelmus Hurkmans, Aaron S.

Publication number: 20120145317Abstract: Method of making a multilayer balloon for a catheter having a nominal working diameter comprises forming a tube having at least a first layer and a second layer having a combined wall thickness. The first layer is made of a first polymer material having a first maximum blow-up-ratio and the second layer is made of a second polymer material having a second maximum blow-up-ratio greater than the first maximum blow-up-ratio. The second layer is an inner layer relative to the first layer. The method also comprises forming the multilayer balloon from the tube in a balloon mold having an inner diameter corresponding to the balloon's nominal working diameter. The at least first and second layers of the multilayer balloon define a compliance less than that of a single layer balloon made of the first polymer material with a wall thickness equal to the combined wall thickness.Type: ApplicationFiled: February 15, 2012Publication date: June 14, 2012Applicant: Advanced Cardiovascular Systems, Inc.Inventor: Jonathan P.

Patent number: 8182640Abstract: A process for bonding aircraft components with a surface, such as an aircraft skin, includes positioning the skin on a tool surface and placing a floorless component on the skin, with bonding agent therebetween. A vacuum bag is placed within the floorless component via a vent in the component, and sealed with opposing inner, lower walls of the component, creating a sealed surface over the skin within the component. Additional vacuum bags seal between lower, exterior legs of the floorless component and either (a) the tool surface (enclosing the skin) or (b) lower walls of adjacent aircraft components. Lower, opposing sides of the adjacent component are also bagged, and loose bag ends are sealed to the tool surface, such that the skin and all feet of the aircraft components are enclosed in vacuum bagging material. The bagged assembly is autoclave cured to bond the aircraft components with the skin.Type: GrantFiled: May 13, 2010Date of Patent: May 22, 2012Assignee: Textron Innovations, Inc.Inventors: Richard Boone, Ronald D.
