PCT No. PCT/EP95/01423 Sec. 371 Date Nov. 18, 1996 Sec. 102(e) Date Nov. 18, 1996 PCT Filed Apr. 15, 1995 PCT Pub. No. WO95/28856 PCT Pub. Date Nov. 2, 1995The invention is associated with a refill cartridge for a stick which applies product by rubbing onto a surface, comprising a tube-like element, which is designed to be tightly closed at both ends and of which one end is designed to fit tightly onto a tube element of the stick; a longitudinally displaceable plunger with a screwthreaded bore-onto which a screwthreaded spindle of the adhesive stick projecting from the tube element is designed to be screwed-being non-rotatably guided in the tube-like element; and the tube-like element being filled with a product which bears against the plunger at one end and, the product in an extension of the screwthreaded bore, is formed throughout with a bore in which the screwthreaded spindle engages when the refill cartridge is fitted onto the stick. The bore in the product is formed via the tube-like element being releasably closed at its free end by a sealingly fitted cap-like closure element, the cap-like closure element being internally formed with a pin-like projection which fills the intended area of the bore extending throughout the product in a liquified state. After the product solidifies, removal of the cap and its associated pin-like projection leaves the bore fully formed in the product.
