Abstract: The present invention relates to an improvement of a nozzle cap for a composite container containing a low-viscosity liquid such as a humidity-curing type adhesive of .alpha.-cyanoacrylate-based adhesive, solvent-volatile type adhesive, various chemicals, food, and ink. A container is provided with a nozzle cap which includes a nozzle connected to a container body and a cap threadably mounted to the nozzle for closing a discharge port of the nozzle. A head of the cap is provided with a column element projecting inwardly for closing the nozzle and a head of the column element is provided with a concave hole into which the tip of the nozzle is removably inserted or fitted. A superior, unique effect is exhibited such that the closure of the nozzle is easily and completely performed, and adhesive or the like adhering to the tip of the nozzle does not spread around and cure, thereby preventing formation of an umbrella- or mushroom-shaped solid material.

Abstract: A liquid applicator bottle for holding and applying liquids, such as fabric paint, to surfaces is formed of a resiliently deformable hollow body. The bottle has a base at one end and sloped shoulders at the other end. The shoulders are angled toward each other to form a neck having an opening. A nozzle unit with a substantially cylindrical stem, sharply tapered to a flange, and having a passage therethrough, is mounted in the opening of the neck. The stem extends axially and outwardly from the flange, which is retained within the neck. A cap is removably mountable on the neck, in a covering relationship to the nozzle unit.

Abstract: A device for closing and resealing an opened container such as a beverage can comprises a threaded cap (13) and a corresponding threaded skirt (22) adapted to be threaded together and apart. The skirt has an upper surface that moves toward and away from a cam surface formed in the underside of the cap as the cap and skirt are threaded together and apart. A compression ring (27) adapted to be compressed and expanded in diameter is captured between the upper surface of the skirt and the cam surface of the cap. As the cap is threaded progressively onto the skirt, the compression ring is engaged by and rides along the cam surface and is thus progressively compressed in diameter. An annular sealing gasket (21) depends from the underside of the cap (13) and is sized to seat about the peripheral portion of the end of the container as the cap moves downwardly toward the top of the container.

Abstract: A pour spout carton for extended shelf life paperboard containers, such as those of the gable top type. A first barrier layer lines the carton interior and a second lines the carton exterior surface. A dispensing opening is formed, as by die cutting, in a panel of the carton. The two barrier layers span the dispensing opening, except for a concentric dispensing hole through them, with the two barrier layers sonically sealed together along an annular zone radially intermediate the dispensing opening and the dispensing hole. The pour spout carries a flange extending from the edge of the dispensing hole to a location radially beyond the dispensing opening, the flange sonically bonded to the outer barrier layer at three radially spaced, concentric zones. The spout screw cap is of a different polymer than the spout, to prevent bonding between the cap and spout.

Extending downwardly from the closure is a support member that presses the fitment against the container.

Abstract: A gas-operated piston cylinder assembly arranged between upper and lower die members of a press. The lower end of the cylinder communicates with a source of high pressure gas and also communicates through a passageway with the upper rod end of the cylinder which is sealed from the surrounding atmosphere. The piston rod has a cross sectional area only slightly smaller than the piston. The passageway between the lower and the upper ends of the cylinder contains a lubricant impregnated member and a by-pass controlled by a check valve which allows gas flowing from the rod end of the cylinder to the lower end thereof to bypass the lubricant impregnated member.

Abstract: A nestable pouring spout assembly for dispensing liquid products from cans and pails. A molded plastic spout has in extended pouring position an enlarged flexible lower wall portion joined to a relatively rigid externally threaded upper wall portion closed off by an imperforate sealing diaphragm. A peripheral sealing channel is disposed about the base of the lower wall portion for securing to a container wall opening neck by means of an overlying metal crimping ring. The upper wall portion receives an internally threaded reclosing cap which is cooperatively engaged within the confines of the crimping ring when the spout is in stored position with the upper wall concentrically nested within the lower wall. Gripping bails integrally formed on the reclosing cap facilitate lifting the spout to raised pouring position by reversing the lower wall portion with respect to the sealing channel from a downwardly extending position to an upwardly extending position.

Abstract: This is a combination pouring spout and closure cap which straddles the same. The closure cap has two annular dependent spaced skirts. The inner of these skirts fits tightly the inner space of the pouring spout and is held in position by coaction of circumferentially spaced helicoidal ridges on the inner face of the outer skirt with an interrupted ridge on the outer face of the pouring spout.
