An applicator has a tubular body containing a liquid to be dispensed. A non-return device is movably disposed in the tubular body rearwardly of and in contact with the liquid for preventing backflow of the liquid. A manually-displaceable piston member is displaceable in the tubular body in a forward direction for pressurizing air admitted into a chamber located in front of the piston member, and a normally closed valve communicates with the chamber and is openable by the force of the pressurized air to apply the pressurized air to the non-return device to urge the non-return device forwardly to thereby pressurize the liquid. A resilient member normally urges the piston member rearwardly to a rear stop position. An air passage communicates the chamber with the exterior of the applicator when the piston member is in the rear stop position, and the air passage is blocked by the piston member during displacement of the piston member in the forward direction. The non-return device comprises one or more kinds of greases, and a float having a front portion embedded in the greases and a rear portion to which is applied the pressurized air.

A decorative article comprising a rod-like base and a seamless cylindrical fabric body covering the surface of the base in an integral form through an adhesive layer. This decorative article can be produced by the following methods. a method which comprises applying a hot-melt adhesive onto the surface of a rod-like base, inserting the base into a seamless cylindrical fabric body, and press-bonding the fabric body with the base while heat-melting the adhesive, thereby adhering said fabric body to said base; a method which comprises inserting a rod-like base made of a thermoplastic resin into a seamless cylindrical fabric body and heat-pressing the surface of the fabric body to melt the surface of the base, thereby adhering the fabric body onto the base with the formed melt; or a method which comprises applying a hot-melt adhesive onto the surface of a rod-like base, inserting the base into a seamless heat-shrinkable fabric body, and shrinking the fabric body while heat-melting the adhesive through heat treatment, thereby adhering the fabric body to the base.
