An object of the present invention is to provide a synthetic resin pipe configured to perform water stop accurately by forming a part connecting convex portions of an outer pipe to be flat without reducing flexibility in order to compose a synthetic resin pipe having flat inner and outer surfaces. A synthetic resin pipe according to the present invention includes an inner pipe formed by spirally winding a belt-like synthetic resin; a spiral reinforcing part formed by spirally winding a synthetic resin having a projected rim with convex portions projecting outside; an outer pipe of belt-like synthetic resin provided so as to connect a part or all of the convex portions arranged in a pipe axis direction; and a shape retaining material for the outer pipe made of a belt-like metal sheet for retaining a shape of the outer pipe flat and buried in or provide to an inner surface of the outer pipe; wherein the shape retaining material for the outer pipe is a synthetic resin pipe wound around the convex portions of the projected rim at predetermined intervals and connecting the convex portions of the projected rim.

An articulating downspout assembly for a downspout system of a building has an elbow component and an end component each having an integrated or integral configuration that cooperatively join with each other to form a hinge. The hinge allows the end component to pivot between a prone position and an upright position. In the upright position the end component is at an angle relative to the elbow component such that a downspout extension section coupled to the end component leans toward and/or against a vertical downspout portion of the building's downspout system. This prevents the end component and thus the downspout extension from spontaneously falling (pivoting) back to the prone position. The integrated configuration of the elbow component is characterized by one or more configured slots while the integrated configuration of the end component is characterized by one or more configured tabs. Preferably, the integrated configuration of one or more configured slots of the elbow component is formed in an upper surface of an end portion of the elbow component, while the integrated configuration of one or more configured tabs of the end component is formed in and projects from an upper end surface of the end component. The resulting hinge between the elbow component and the end component does not stress the material (e.g. metal) of either the elbow component or the end component.

The application discloses a flexible multilayer tubular package. The package is for an intermittent catheter. The intermittent catheter is coated with a hydrophilic coating, which becomes slippery when in contact with a swelling medium. Thus, the tubular package of the application can withhold the swelling medium for a long time and at the same time being flexible and bendable. Furthermore, the application discloses a catheter package set, which comprises a multilayer tubular package, an intermittent catheter and a swelling medium.

Included in this disclosure is a downspout drain filter for rain gutter downspouts. The downspout drain filer comprises elongated housing having an axis, a top portion, and a bottom portion. A transition portion connects the top portion to the bottom portion. The top portion includes an intake opening, a top portion perimeter, a debris opening, a filter attachment location, and a downspout attachment location. The downspout attachment location includes a flexible collar that defines a downspout attachment location perimeter that is less than the top portion perimeter. The bottom portion includes a flexible collapsible body that extends from the transition portion. A connection end is positioned opposite the transition portion as a part of the bottom portion. A filter is positioned in the top portion to direct debris out the debris opening and to permit liquid to pass to the bottom portion.

A flexible collapsible corrugated drain pipe has a corrugation structure that permits a tight bending radius and relatively facile collapsing and expansion of corrugations, thereby permitting convenient manipulation and installation of drain pipe and packaging, display, storage and transportation of the collapsed pipe sections.

Portable Flexible and Extendable Drain Pipe

A manual pump is provided having a corrugated section defining a spring walled short chamber and enabling the pump to be manufactured with only three integrally formed pieces utilizing blow or vacuum molding processes, and optionally one or two check valve balls.
