ABSTRACT:
A new method fills a dispenser with cyanoacrylate adhesive from the rear. The container is sealed by a pressed-in base section (4). The latter has a vent opening which can be sealed, preferably by a plug (68) pre-mounted on it. Preferably the contacting surfaces of the container and this base have an oval shape. In this novel method, the container is first filled, while the end is still open. The base is then pressed in, sealing it onto the container. In so doing, the air displaced, is released through the base vent. During the final phase of pressing-in, the vent is plugged, irreversibly sealing it. Also claimed is an adhesive dispenser, essentially as described, with further preferred detail of the seals, the pipette construction of the container and a slot valve in the plug unit. USE--A dispenser filling method and dispenser, especially suitable e.g. for a super glue. ADVANTAGE--This method allows the container to be filled without the base in place, hence avoiding filling through a very fine hole or nozzle. The latter course would involve a danger of air entrainment and/or foaming. Air per se has no harmful effect, but its water vapor content causes undesirable polymerization of cyanoacrylate adhesives. The method makes a leakproof and secure fastening at the base, avoiding welding or adhesion. A simple, low cost mechanical stage is all that is required. Further manufacturing advantages of the base and plug are detailed in the text.
