Definitions

  • THIS INVENTION relates to a holder for an applicator and a dispenser for liquids or pastes having such a holder.
  • typewriting correction fluid for example Tipp-Ex (Registered Trade Mark) for use in offices, plumbers' glue and liquid plastics, touch up car paint, soldering flux and many other products similarly packed.
  • a dispenser for liquids or paste having a first chamber for containing liquid or paste, a second chamber, means for supporting an applicator so that the applicator is in communication with the first and second chambers and means for expanding the second chamber to cause liquid or paste to be sucked up from the first chamber onto the applicator.
  • a holder for an applicator for applying liquid or paste to a substrate comprising means for supplying liquid or paste to an applicator in the holder and sealing means for providing a seal between the holder and a cap for closing an opening of a container for liquid or paste so that, when the holder is received in the container opening, relative movement of the holder and the cap causes liquid or paste to be supplied by suction to an applicator in the holder as the cap is removed from the container and causes liquid or paste to be returned to the container as the cap is replaced to close the container opening.
  • a dispenser embodying the invention enables the viscosity of the liquid or paste to be sustained, by being easy to open and close. Moreover, the dispensing of the liquid or paste product may be largely improved because a top quality brush, which eliminates the repeated supply of a poor quality brush with each container, may be used as the applicator since the brush and the applicator supporting means or holder can be reused with a new first chamber or container.
  • FIGURE I is a vertical cross-section through part of a first embodiment of a dispenser for liquid or paste in accordance with the invention
  • FIGURE 2 is a vertical cross-section through part of a second embodi ⁇ ment of a dispenser for liquid or paste in accordance with the invention.

  • the brush holder 3 has further been provided, intermediate the end 3a thereof and the stopping rim 14 with a groove or several grooves 15 to receive the or a respective 0-ring 16, the size or number of the 0-r ⁇ ngs and grooves being determined in accordance with the contents of the container 2.
  • the 0-ring sealing means and the cap define a second chamber Grid the brush communicates with both the first and second chambers.
  • the brush 4 is sunk deep inside the holder 3 so as to allow room for any overflow of the container contents.
  • the top edge of the brush holder 3 has a very smooth and accurate edge which provides a tight seal 3' between the cap 5 and the brush holder when the cap is put on.
  • the cap 5 may be of any desired external shape but is preferably made so that the outside diameter is large enough to provide a good gripping surface to enable the cap to be removed from the container.
  • Cap 5 defines a small second chamber to accommodate the brush 4 and is totally sealed by the brush holder's top edge once the two are in a closed or engaged condition.
  • a substantially cylindrical inner surface are 19 of the cap 5 is provided with a high or smooth finish to enable the 0-rings to move up or down along that cylindrical surface area.
  • FIG. 1 shows an alternative embodiment of a dispenser in accordance with the present invention. Again, it should be appreciated that the dispenser has rotational symmetry about the axis 6.
  • the dispenser comprises a container or bottle 19 having an elongate neck 20.
  • the neck 20 is formed with a screw-thread 21 for engaging a complementary screw-thread 22 of a cap 23 for the bottle.
  • a plurality of 0-rings 24 are carried by respective grooves 25 formed in the neck 20 of the bottle 19.
  • the 0-rings 25 serve to provide a seal between the cap 23 and the neck 20 of the bottle when the cap is screwed onto the bottle.
  • An applicator supporting means or holder 26 snap-fit engages within the neck of the bottle.
  • the holder 26 is provided with a circumferential protrusion 27 which engages in an annular recess 28 formed in the interior surface of the neck 20 of the bottle to ensure that the holder 26 snap-fits into the correct position within the neck of the bottle.
  • the brush holder 26 is provided with an annular flange 29 which, when the brush holder is snap-fitted within the neck 20 of the bottle, extends over a free edge of the neck 20 of the bottle 19.
  • a circumferential surface 29£ of the flange 29 is formed with a diamond pattern or otherwise roughened to assist in the removal of the brush holder from the container or bottle 19.
  • the brush holder 26 is provided with slits or slots 30 for flexibility and so as to reduce the amount of material required to manufacture the brush holder 26.
  • An applicator in the form of a brush 31 is mounted in a cavity formed in the brush holder 26 as in the arrangement shown in Figure I by means of a brush mounting ring 32.
  • the brush - 31 communicates with the first chamber formed by the bottle or container 1 by a channel 33 extending centrally through the brush and the brush holder 26.
  • An interior surface of the cap 23 is formed with an annular V-shaped cross section projection 34 which is arranged to engage a top surface of the flange 29 of the brush holder when the cap is fully screwed onto the neck of the bottle so as to provide a fluid tight seal to prevent any liquid or paste escaping from the dispenser.

Abstract

Dans un mode préférentiel de réalisation, le distributeur (1) comporte un récipient (2) et un capuchon (5) engageant par filet de vis un col (12) du récipient. Un support d'applicateur (3) s'engage par blocage automatique dans le col (12) du récipient et soutient un applicateur ayant la forme d'une brosse (4), de telle manière que la brosse (4) s'étend dans une seconde chambre déterminée par le capuchon (2) et le mécanisme de fermeture ayant la forme de bagues annulaires (16) portées par le support de brosse (3). Lorsque le capuchon (5) est dévissé pour ouvrir le récipient (2), la seconde chambre déterminée par le capuchon et le mécanisme de fermeture est développée afin d'amener le liquide ou la pâte à être aspiré à partir de la première chambre déterminée par le récipient (2) jusque sur la brosse (4). De manière similaire, lorsque le capuchon (5) est réengagé avec le récipient (2) afin de fermer le récipient (2), le mouvement du capuchon amène la seconde chambre à se contracter afin de repousser le liquide ou la pâte dans le récipient (2). Dans un mode alternatif de réalisation, les joints à bagues annulaires sont prévus entre un col allongé du récipient et le capuchon, plutôt qu'entre le support de brosse et le capuchon.
