Definitions

  • the present invention relates to apparatus for preparing disinfectant wipes, and a method of using the apparatus and an assembly for making the apparatus. b. Related Art
  • Disinfectant wipes are widely used for cleaning and disinfecting surfaces, both in the home and in clinical environments. It is known to provide wipes which are pre- wetted with a disinfectant and put up in a pack. A problem with such wipes is that they are prone to drying out once the pack has been opened. They are also unsuitable for disinfectants with active ingredients that are unstable over time, such as chlorine dioxide.
  • a disinfecting liquid is applied to a clean, dry wipe by pouring or spraying the liquid from a vessel, and then the wipe is used to disinfect a surface.
  • the disinfecting liquid may be prepared shortly before use from a two-part system if the active ingredient will deteriorate significantly over time.
  • a chlorine dioxide disinfectant solution may be prepared by mixing a chlorite solution and an acid.
  • An example of a prior art disinfectant wipe system is described in WO 2005/01 1756.
  • An aspect of the invention provides an apparatus for preparing disinfectant wipes.
  • Other aspects of the invention provide an assembly for manufacturing the apparatus, and a method preparing disinfectant wipes using the apparatus.
  • the invention provides a simple apparatus for preparing disinfectant wipes which dispenses a fixed volume of liquid.
  • a preferred embodiment additionally provides a disinfectant wipe with improved uniformity of wetting and without wastage of disinfectant liquid.
  • FIGS. 1a - 1 h show stages in the preparation of a disinfectant wipe using apparatus in accordance with an aspect of the invention
  • Figure 2 is a vertical sectional view through the apparatus of Figure 1 ;
  • Figure 3 is a plan view of the base of the wipe compartment
  • Figures 4 and 5 are perspective side views of the dosing unit of the apparatus of Figure 1 ;
  • Figures 6 and 7 are, respectively, bottom and top views of the dosing unit of Figures 4 and 5;
  • Figure 8 is a vertical sectional view through apparatus in accordance with another embodiment of the invention.
  • Figures 9 and 10 are, respectively, perspective and vertical sectional views of apparatus in accordance with a further aspect of the invention.
  • Apparatus 2 for preparing disinfectant wipes comprises a vessel 4 for a liquid disinfectant 16 ( Figure 2).
  • the vessel 4 has a dosing unit 14 mounted on a neck of the vessel.
  • the dosing unit 14 has a cap 7 with a cap top 8 and a cap body 6 including a wipe compartment 10 beneath the cap top 8.
  • the cap top 8 is partly or completely removable to allow access to the wipe compartment 10.
  • the cap top 8 is hingedly connected to the cap body 6 but could be completely removable or mounted in a different manner such as by sliding.
  • the dosing unit 14 delivers a predetermined volume of disinfectant to a dry wipe.
  • the dosing unit in this embodiment includes a generally cylindrical body 18 with at least one inlet 22 in fluid communication with the inside of the vessel 4, and a dosing reservoir 28 in fluid communication with the wipe compartment 10.
  • the dosing reservoir 28 is between a reservoir wall member 32 and the sealed base 20 of the dosing unit.
  • the dosing reservoir 28 is in fluid communication with an outlet 26 of a conduit 24 via an opening 34 in the reservoir wall member 32.
  • the underside of the base 9 of the wipe compartment 10 provides an inlet reservoir 30 in fluid communication with the inlet 22 and with the dosing reservoir 28.
  • the lower end of the conduit 24 is located within the dosing reservoir 28, and liquid in the conduit 24 is at the same level as liquid in the dosing reservoir surrounding the conduit.
  • the base 9 of the wipe compartment 10 has a hole 1 1 ( Figure 3) into which the outlet 26 on the conduit 24 is a close fit.
  • liquid in the inlet reservoir 30 drains into the dosing reservoir 28.
  • FIGS 1 a-1 h illustrate steps in the preparation of a disinfectant wipe.
  • the user flips open the cap top 8 to expose the wipe compartment 10.
  • the user takes a dry wipe 12 and places it in the wipe compartment.
  • the wipe may be a conventional sheet of woven or non-woven fabric material 12a, which the user may need to compress to fit in the wipe compartment 10.
  • the wipe may be a so-called towel tablet or pill wipe 12b of a size suitable for locating in the wipe compartment without further compression.
  • Wikipedia describes a towel tablet as“a fibre towel that is compressed into the shape of a small tablet. The towel tablet expands when water is added to the tablet.” Suitable towel tablets or pill wipes are commercially available.
  • the user With the dry wipe 12 in the wipe compartment, the user closes the cap top. The user then inverts the vessel 4 so the cap 7 is at the bottom ( Figure 1f). A quantity of disinfectant liquid drains from the dosing reservoir 28 into the wipe compartment 10 and is absorbed by the wipe 12.
  • the dosing reservoir in this example delivers about 10 ml of liquid to the wipe compartment. Typically, the dosing reservoir will be dimensioned to dispense from about 5 ml to about 25 ml of disinfectant liquid.
  • the user After allowing a few seconds for liquid to drain from the dosing reservoir 28 into the wipe compartment 10, the user turns the apparatus back to a dispensing position, with the cap at the top. The user opens the cap top 8 to expose the wipe 12, which is now wetted with disinfectant liquid (Figure 1 g) and removes the disinfectant wipe 12 from the wipe compartment 10 ( Figure 1 h) for use.
  • the user Before first use, the user inverts the vessel to transfer disinfectant into the inlet reservoir, and then returns it to the dispensing position with cap at the top and disinfectant in the dispensing reservoir.
  • the apparatus is then primed and ready for use as described above.
  • conduit 24 is integrally formed with the cap 7.
  • the cap 7 fits on an outer wall of the dosing reservoir 28 and/or the region where the inlet 22 is provided.
  • An inner facing surface of the outer wall is provided with a screw thread 36 for screwing the assembly onto the neck of a bottle or other vessel.
  • Substantially all of the liquid that enters the wipe compartment 10 is absorbed by the wipe 12.
  • the arrangement facilitates more uniform impregnation of the wipe with disinfectant than prior art methods. Wetting of the wipe 12 by disinfectant is achievable by one-handed operation without requiring the user to hold the dry wipe in one hand and apply disinfectant from a vessel in the other hand.
  • the cap body 6 has a ceiling member 15 which surrounds the outlet 26.
  • the outlet 26 conveys liquid from the dosing reservoir 28 when the apparatus is inverted so that the outlet 26 faces down. This provides a metered volume of disinfectant liquid to be dispensed from the apparatus onto a wipe member or other item (not shown).
  • the cap top 8 is provided with a stopper 13 for sealing the outlet 26 when the cap top 8 is closed.
  • the disinfectant liquid may be a chlorine dioxide solution prepared shortly prior to use according to methods and reagents known per se.
  • the invention is not limited to the use of chlorine dioxide; other suitable disinfectant liquids may be used.

Abstract

L'invention concerne un appareil (2) permettant de préparer des lingettes désinfectantes (12), l'appareil comprenant : un récipient (4) pour un désinfectant liquide (16) ; une unité de dosage (14) comportant un bouchon doté d'une partie supérieure de bouchon (8) et d'un corps de bouchon (6) comprenant un compartiment à lingettes (10) en dessous de la partie supérieure de bouchon (8), la partie supérieure de bouchon (8) étant partiellement ou complètement amovible pour permettre l'accès au compartiment à lingettes (10) ; l'unité de dosage (14) comprenant une entrée (22) en communication fluidique avec l'intérieur du récipient (4), et un réservoir de dosage (28) en communication fluidique avec le compartiment à lingettes (10) ; l'unité de dosage comprenant un réservoir d'entrée (30) en communication fluidique avec l'entrée (22) et avec le réservoir de dosage (28). Lorsque le récipient (4) est orienté vers une position de chargement avec le bouchon au fond, le liquide contenu dans le récipient pénètre dans le réservoir d'entrée (30) et le liquide contenu dans le réservoir de dosage (28) s'écoule dans le compartiment à lingettes (10). Lorsque l'orientation du récipient (4) passe de la position de chargement à une position de distribution avec le bouchon en haut, le liquide contenu dans le réservoir d'entrée (30) s'écoule dans le réservoir de dosage (28).
