Abstract: A writing implement with a sealing element on a closing cap is mountable over a writing insert having a concentric writing tip, wherein the projecting part of the writing insert is provided with abutment faces and threads on which the closing cap is screwed.

Abstract: A modular writing instrument cap system is disclosed, in which each individual cap comprises an elongated tubular portion having an open end and a closed end. Near the closed end the cap is internally provided with a seal member adapted to seal with a writing instrument holding quick-drying ink. Near the open end, the tubular portion is internally provided with a catch for removably securing the cap on a writing instrument. Externally on the closed end, the cap is provided with a transversely-oriented open ended tubular barrel. The barrel is configured to receive an internally threaded sleeve, terminator rings and screws which thread towards one another through the rings into the opposite ends of the sleeve in order to hold the assembly together and secure a bail to it. The ends of the barrel and corresponding ends of the terminator rings are cooperatively notched to accommodate the legs of the bail.

Abstract: A writing instrument having a closure cap assembly (1, 2, 3, 4 and 5) which can be placed in a sealing manner on the writing tip (20), whereby a positive engagement with an indentation in the writing tip is established via an elastically deformable finger (8), when the closure cap is in place on the writing tip. On the inner face of the arm (8), oriented toward the writing tip (20), at least one cam face (13) is located in a chord plane of the circle forming the closure cap opening. Whereupon a twisting of the entire mounted closure cap assembly (1, 2, 3, 4 and 5) brings the cam face (13) into engagement with a correspondingly formed wedge face (27) of the writing tip (20), so that the arm (8) is pivoted radially outward, and the closure cap can be removed.

Abstract: An instrument for writing or drawing comprises a main body containing a writing element and a closing member pivotally connected to the former by resilient means allowing for a reciprocal rotation of the parts.

Abstract: A roll-on applicating package is described which is adapted to dispense products incorporating a liquid which has a very low surface tension. The liquid tends to penetrate mechanical seals and migrate to outer surfaces of ordinary applicating packages, creating an unsightly appearance and a negative tactile impression. The package of the present invention includes a means to establish a primary seal and includes, within its closure, an absorptive insert adapted to make continuous contact with a lip surrounding the applicating roller when the package is sealed. The insert is made of a non-hygroscopic material which possesses an ability to draw the liquid into its exterior by capillary action. Because of the preferential migration of the liquid into the insert, outer surface fouling of the package is obviated.

Abstract: A closure cap for a writing instrument such as a ink pen and the like has an outer generally cylindrical cap housing within which is a sealing sleeve having a closed end to close one end of the cap housing. A slide sleeve of a hard rigid material is retained against axial movement within the sealing sleeve. A closure member of a soft resilient durable material is axially slideable within the slide sleeve and is acted upon by spring means which may include a helical spring or axially extending resilient strips.
