A flow device is provided for sensing air flow and includes a body having at the opposite ends thereof coaxial bores. Counterbores extend inwardly from the coaxial bores and are interconnected by a restricted bore having lateral bores extending from opposite ends thereof to provide a pneumatic pressure drop. The bottom portions of the respective counterbores are relieved to provide a pair of troughs for water collection outside of the normal air flow area so that water can accumulate for an extended period of time before interferring with pressure drop readings.

Flow device with water trap

Nebulizer cup

A method of making a thin-walled tubular container. The container defines a head portion with access means to the contents of the container, and a tail portion defining a sealed line in the tail portion, joining sides of the container into a sealed end with a flat plastic piece being formed integral with the sealed line and extending away therefrom. In accordance with this invention, a pair of spaced rod members are formed as an integral part of the flat, plastic piece, the rod members extending transversely of the longitudinal axis of the container. The flat plastic piece also defines a portion thereof between the rod members which is thinner than any remainder of the plastic piece spaced from the rod members. Accordingly, the rod members and intermediate portion therebetween provide an improved and stronger tail seal.

Method of making a flexible, collapsible container for liquids with

A molded collapsible solution container which defines a body portion having an integral neck portion and a semi-rigid shoulder portion at one end thereof, and is sealed at its opposite end. In accordance with this invention, transverse lines of folding weakness are defined along opposite edges of the shoulder portion to facilitate the collapse of the container.

Molded collapsible solution container having transverse fold lines

A flexible, collapsible container having walls essentially 0.01 to 0.03 inch thick and defining relatively thin lines of folding weakness in the container to facilitate flat collapse. The thickness of the lines of folding weakness is less than that of the surrounding walls. The cross-sections of the lines of folding weakness define arcs, the outer surfaces of which have a circumferential length which is 40 to 60 percent greater than the direct width of the lines of folding weakness. Preferably, the container is made of a relatively stiff polyolefin plastic such as polyethylene, polypropylene, or copolymers thereof of similar stiffness, particularly biaxially oriented materials.

Flexible collapsible container

A thin-walled tubular container and a mold for making it is disclosed. The container defines a head portion with access means to the contents of the container, and a tail portion defining a sealed line in the tail portion, joining sides of the container into a sealed end with a flat plastic piece being formed integral with the sealed line and extending away therefrom. In accordance with this invention, a pair of spaced rod members are formed as an integral part of the flat, plastic piece, the rod members extending transversely of the longitudinal axis of the container. The flat plastic piece also defines a portion thereof between the rod members which is thinner than any remainder of the plastic piece spaced from the rod members. Accordingly, the rod members and intermediate portion therebetween provide an improved and stronger tail seal. A novel method for making such containers is also shown.
