The 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.
A refill cartridge for a stick applicator which applies product by rubbing the product onto a surface, such as with an adhesive stick, comprising:
A method for filling a refill cartridge with initially liquid and subsequently solidifying product, said refill cartridge including a hollow tubular body for containing said product, a longitudinally displaceable plunger including a centrally located screwthreaded bore, said plunger being initially retained within an opening in a bottom end of said tubular body, a cap-like closure element internally formed with a centrally located elongated pin-like projection, whereby when said closure element is secured to a top end of said tubular body for closing off the same, said pin-like projection extends through said product thereby forming an elongated central bore through said product;
