摘要： An improved paperboard multiple can carrier made of multilayered laminated paperboard which has at least two layers of recycled paper and two layers of virgin paper. Tearing of the paperboard is prevented by multiple indentations or notches circumferentially extending around the orifices through which cans and fingers are inserted.

摘要： A gas safety vent device for application to a service pipe of predetermined outside diameter prevents leaking gas from seeping along the exterior of the pipe and entering a building by diverting the gas away from the pipe and venting the same to the atmosphere. The device has a chimney extending from a lower end to an upper end and a lower portion providing a chamber in communication with the chimney and oppositely facing gas sealing and gas entering faces. The gas sealing face surrounds the pipe in gas sealing relationship therewith. The gas entering face has an opening and wire mesh material in the opening has an outer periphery secured to the wall of the opening and an inner periphery defining an inner circle of a diameter substantially the same as the outside diameter of the pipe. The area of the wire mesh material is substantially greater than the area of the circle and the radial dimension of the wire mesh material is everywhere substantially greater than the radius of the circle. Seeping gas enters the chamber through the wire mesh material and exits the device through the chimney. The vent device is formed in pairs for direct installation on a pipe, and also includes an adapter sleeve formed in pairs for installation on a pipe of lesser outer diameter.
