Definitions

• This invention is concerned with containers, and is particularly related to containers for correction fluids which are commonly used to cover mistakes when making writing or typing corrections.
• correction fluid is commonly supplied in a bottle equipped with an applicator, typically a brush or pad mounted at the end of a stem carried by a cap of the bottle * It is well known for correction fluid bottles to be fitted with neck inserts.
• the neck insert is generally tubular and defines a passage through which the applicator is withdrawn from and inserted into the bottle.
• the neck has two functions. Firstly, it prevents excessive amounts of fluid being withdrawn from the bottle on the applicator. Secondly, by projecting into the storage chamber defined within the bottle, it can serve to prevent spillage should the bottle be accidentally tipped onto its side when the cap is removed.
• the invention addresses the problem explained above and as a solution the invention provides a container for correction fluid comprising a chamber, a neck defining passage leading from the chamber, the neck having an annular inner end with at least one protrusion extending therefrom into the chamber, without radially corifining the passage as defined at the inner end of the neck, for drops of fluid running back through the neck to collect at the free end thereof and fall back into the chamber.
• the protrusion or protrusions conveniently extend substantially parallel to the axis of the passage and to encourage drops of fluid to fall under gravity from the free lower end of a protrusion, the protrusion preferably tapers to a point.
• protrusions could be formed by teeth or spikes integral with a neck insert, or by separate elements, e.g. pins fastened to the neck.
• the protrusion is defined by an inclined inner end face of the neck insert. The end face may be at an angle of less than 45°, e.g. 20°-40°, to the axis of the neck passage.
• Figure 1 is an axial cross-section through a correction fluid dispenser according to the invention
• Figure 2 shows the neck insert in axial cross section and on an enlarged scale
• Figure 3 is a perspective view showing the applicator brush and the stem carrying it.
• the correction fluid container illustrated in Figure 1 comprises a conventional moulded plastics bottle 1 defining an interior chamber 2 for storage of correction fluid and having an integral neck section 3 which is externally screw threaded and which defines an opening into which a neck insert 4 is fitted with a good friction fit.
• the neck insert has an external flange at its outer end to rest on the rim of bottle neck section, and form a neck passage for an applicator.
• the applicator consists of a brush 6 mounted at one end of a stem 7, the outer end of the stem being attached to the bottle cap 8 which is internally screw- threaded for co-operation with the external thread on the neck section 3.
• the passage formed by the neck insert 4 includes a mouth portion 10 (Fig 2) of relatively large diameter, an inner throat portion 11 of smaller diameter, and an intermediate tapering portion 12.
• the inner end face 13 of the insert 4 lies in a plane inclined to the axis of the passage at an angle of 30°.
• the inner end of the neck defines a protrusion 15 which tapers to a sharp point 16.
• Correction fluid running down the inner surface of the neck passage having been deposited on this surface such as during withdrawal of the applicator brush 6 through the neck passage, or by the user wiping fluid from the brush by means of the edge of the insert mouth, runs straight down under gravity until it reaches the bottom edge, but it does not immediately fall from this edge due to surface tension.
• the drops of fluid flow around the bottom rim towards the extremity of the protrusion 15 where they collect and join together until their combined weight is sufficient to overcome the surface tension and the drop of fluid falls from the point 16 of the protrusion 15 into the chamber 2 in the bottle. It may be noted that should a drop of fluid remain and dry at the point of the protrusion, as depicted in broken line in Figure 2, it does not seriously impede passage of the applicator brush because the inclined face 13 defines a relatively large opening at the inner end of the neck and the brush is easily deflected laterally to pass over the dried fluid.
• the applicator stem 7 is shaped to scrape the surface of the passage.
• the stem 7 has parts 17, 18 each of uniform square cross section for cleaning the mouth and throat portions 10,11 of the neck passage, respectively, and a tapered part 19 of square cross- section for clearing fluid from the tapered portion 12 of the neck passage.
• the cap 8 is- screwed onto the bottle neck the parts 17,18,19 of the stem are rotated to clean the respective portions of the passage.
