A manufacturing method for manufacturing a container with a handle, the method including a primary blow molding step of blow-molding a preform made of a polyethylene terephthalate resin to mold an intermediate molded body, and a secondary blow molding step of assembling the handle to a container body, which is made of the intermediate molded body expanded inside a blow mold, by arranging the intermediate molded body inside the blow mold which holds the handle by an inner surface thereof and blow-molding the intermediate molded body in a state where the handle is brought close to the intermediate molded body.

An ostomy appliance includes a waste collection bag that is molded to form a front wall that continuously extends to form both a side wall and a rear wall. The rear wall is spaced apart from the front wall when the waste collection bag is empty. A bottom of the waste collection bag is defined by a curved bottom wall that continuously extends from both the front wall and a rear wall. The waste collection bag is formed to include a longitudinal curvature within at least one of the front wall and the rear wall, and a connector is integrally molded into the rear wall of the waste collection bag around a waste inlet.

A method for manufacturing a fuel tank or filling pipe including a wall made of thermoplastics material and a fibrous reinforcement over at least part of the surface thereof, the method including: heating the fibrous reinforcement to bring the fibrous reinforcement into an at least partially molten state; introducing the heated fibrous reinforcement, and the wall in at least partially molten state, into a mold; and welding the fibrous reinforcement to the wall using pressure of a gas which inflates the wall and presses the heated fibrous reinforcement firmly against the wall in the molten state.

Fuel tank for a motor vehicle, comprising a plastic wall which delimits a storage volume for storing fuel, comprising one or more reinforcing elements for reinforcing the plastic wall, with at least one reinforcing element being connected to an outer side of the plastic wall that faces away from the storage volume, characterized in thata maximum thickness of at least one reinforcing element measured normal to the plastic wall is greater than the wall thickness of the plastic wall.

A container with a handle, in which a handle is engaged with a portion of the container, is manufactured by arranging the handle in a handle arrangement part, inserting a bottomed tubular preform into a cavity of a mold and performing blow molding. The mold includes an inner wall surface that forms an external shape of the container and a pressurizing member that forms a handle engaging part engaging with the handle to a portion of the container, and the pressurizing member is capable of moving between a first position which is a position at an outer side of the inner wall surface and a second position at which a portion of the inner wall surface is formed.

A method for producing a flexible pouch made of flexible thermoplastic material, including steps of: (i) preparing hot flexible thermoplastic material in a pasty state, (ii) placing a so-called proximal pre-molded insert onto a mounting such that the insert is arranged in a ring around the mounting, (iii) coating all or part of the insert with hot flexible thermoplastic material in the pasty state, (iv) locking the blow-mold shells around the insert, and (v) injecting a pressurized gas into the chamber so as to expand the sleeve from inside onto the inner surface of the mold or expand the sleeve from the outside by creating negative pressure inside the chamber.

Provided is a method for welding an accessory part made of a thermoplastic resin to a parson which is being molded into a tank body. The method includes steps of: forming the accessory part to include an annular portion having an annular shape and a plurality of projections each projecting from the annual portion in a radially inward direction; and pressing the annular portion and the projections into the parson to be welded to the parson. Also provided is a welding structure of a tank body made of a resin and an accessory part made of a thermoplastic resin and welded to a wall surface of the tank body. The accessory part includes: an annular portion having an annular shape; and a plurality of projections each projecting from the annular portion in a radially inward direction. The annular portion and the plurality of projections are welded to the wall surface.

An ostomy collecting bag is provided. The collecting bag has a continuous wall with a curvature instead of sealed edges. The collecting bag is truly three-dimensional. The collecting bag may be obtained by injection blow-moulding or extrusion blow-moulding. Methods of producing an ostomy collecting bags by either injection blow-moulding or extrusion blow-moulding is also provided. In injection blow-moulding, a pre-form is injection moulded and subsequently the pre-form is blow-moulded into an ostomy collecting bag. In extrusion blow-moulding, a tube is extruded and subsequently blow-moulded into an ostomy collecting bag. The ostomy collecting bag can thus be made without seals at the edges, which provides a more flexible collecting bag with a larger interior volume.

A balloon catheter is provided that may be used to dilate hardened regions of a stenosis. The balloon catheter is provided with one or more dilation elements that extend along a surface of a balloon. Each dilation element is monolithically connected to an outer surface of the balloon by a connector. The connector is sufficiently sized and designed to undergo stress-induced plastic deformation incurred during blow molding so that a significant portion of each of the dilation elements does not become absorbed into the wall of the final blow molded balloon, thereby maintaining the structural integrity of each of the dilation elements. The dilation element has a flattened outer surface along at least proximal and distal neck portions of the balloon.
