Definitions

  • the invention relates to handheld dispensers and an aspect thereof, for metering flowable material, particularly but not exclusively granules or powders.
  • a variety of industrial, agricultural household operations require the metered dispensing of flowable material, for example metering of an accurate quantity of concentrated material prior to dilution.
  • Such operations involve the step of transferring material from a supply vessel into a separate metering receptacle, which is then used to dispense the material.
  • Such an operation is inconvenient and time-consuming, and indeed, may not be possible if dispensing is to be performed outdoors, particularly during inclement weather. These problems are exacerbated if hazardous material requires dispensing.
  • a handheld dispenser comprising: a vessel for holding material to be dispensed, the vessel having an aperture; and an assembly attached to the vessel and rotatable between first and second positions, which assembly has a dispensing outlet and a metering chamber; whereby, in the first position the metering chamber is in fluid communication, via the aperture, with the vessel but not with the outlet and in the second position, the metering chamber is in fluid communication with the outlet but not with the vessel, characterised in that the portion of the vessel which attaches to the assembly, is shaped to define a channel such that when the assembly is attached to the vessel and adopting the second position, the channel and the assembly define a passageway which connects the outlet with the chamber, and where the aperture is positioned substantially on the same radial plane as the channel.
  • the assembly is rotated to the position where the aperture is in fluid communication with the metering chamber (first position).
  • the dispenser is then orientated such that material, contained within the vessel, flows via the aperture and into the metering chamber. Whilst maintaining the dispenser in this orientation, the assembly is rotated to a position where the metering chamber is in fluid communication with the outlet (second position) whereupon the dispenser is orientated so as to dispense the metered amount of material from the metering chamber.
  • material can be metered and dispensed conveniently without exposing the operator to the material, which may be hazardous.
  • the invention enables the manufacture of dispensers that are compact and which can be fabricated using a conventional plastic moulding process at low cost.
  • the vessel when the chamber and the aperture are not in fluid communication, the vessel is completely sealed.
  • This feature of our invention provides several advantages. Firstly, it prevents moisture entering the vessel, which may affect the materials fluent properties, particularly if it is hygroscopic. Thus, hygroscopic material can be stored in the dispenser for prolonged periods without requiring further protection from moisture. Secondly, this feature makes the dispenser a practical device, enabling it to be carried in any orientation without the risk of spillage, for example in a pocket or rucksack.
  • a metering device comprising: an adapter for attachment to a vessel, which adapter has an aperture, and an assembly attached to the adapter and rotatable between first and second positions, which assembly has a dispensing outlet and a metering chamber; whereby, in the first position the metering chamber is in fluid communication, via the aperture, with the vessel but not with the outlet and, in the second position, the metering chamber is in fluid communication with the outlet but not with the vessel, characterised in that the portion of the vessel which attaches to the assembly, is shaped to define a channel such that when the assembly is attached to the vessel and adopting the second position, the channel and the assembly define a passageway which connects the outlet with the chamber, and where the aperture is positioned substantially on the same radial plane as the channel.
  • This aspect has all the advantages described for the first aspect, and additionally enables the invention to be used in conjunction with vessels of different capacities. Furthermore, it is envisaged that this device may encourage industry to establish a standardised vessel connector for connection with the adapter of the device. This would have environmental advantages facilitating the development of returnable vessel systems.
  • the outlet and chamber are diametrically opposed on the assembly about its axis of rotation. A compact dispenser and device is thereby produced.
  • the assembly is removably attached to the vessel or adapter. This facilitates cleaning of the dispenser or device, for example, if differing materials are successively used.
  • the capacity of the metering chamber may be varied.
  • This embodiment is particularly advantageous enabling the dispensing of metered amounts of material independent of its predecessor. Therefore the invention overcomes a drawback inherent with a number of prior art dispensers (for example EP 269 283) wherein the metering chamber is of fixed capacity.
  • the metering chamber is elongate and its capacity may be varied by means of a metering piston movable within an elongate metering cylinder.
  • This embodiment provides a number of advantages. It provides a simple and accurate variable capacity chamber.
  • the elongate chamber allows the operator to rotate the chamber about the vessel or adapter with ease.
  • the elongate metering cylinder or piston may incorporate information relating to the amount of material to be dispensed. Such information may be in the form of weight units, for example metric and/or imperial. Additionally, the information may be in the form of dose or application rates, for example USA rates or UK rates. Typically, such information is conveyed by way of graduations, which may be incorporated as part of a moulding process, or added subsequently for example by printing.
  • Figure 1 shows an exploded perspective view of a metering device according to the second aspect of the invention.
  • Figure 2 shows a cross sectional view of the assembled metering device of Figure 1 viewed along axis AA.
  • Figure 3 shows a cross sectional view of the assembled metering device with the piston extended viewed along axis BB of Figure 2.
  • Figure 4 shows a cross sectional view of the assembled metering device viewed along axis CC of Figure 2.
  • Figures 5 to 7 show the dispensing operation using a dispenser according to the first aspect of the invention.
  • metering device 32 which comprises adapter 1 , assembly 2 and metering piston 3.
  • Adapter 1 comprises a continuous circular wall 4 closed at one end 5, which wall carries an internal thread (not shown) for attachment to a vessel (also not shown).
  • Channel 6 connects diametrically opposed points on the wall 4 and aperture 7 is positioned at a point on the wall equidistant between the ends of the channel.
  • Flange 8 surrounds the rim of wall 4 opposite to closure 5.
  • An internal part of the adapter is shaped so as to provide a deflecting means 9, so as to facilitate passage of material through aperture 7.
  • Assembly 2 comprises a continuous circular wall 1 1 closed at one end 1 2, the wall 1 1 having an opening 1 3 leading to a metering cylinder 1 4.
  • Metering cylinder 1 4 extends radially outwards from wall 1 1 .
  • Wall 1 1 further contains an outlet 1 5 diametrically opposed to opening 1 3.
  • Assembly 1 2 has a shaped flange 1 6.
  • Adapter 1 and assembly 2 are sized and shaped such that adapter 1 is a rotatable fit within assembly 2.
  • the size and shape of aperture 7 and opening 1 3 are equal and positioned such that when assembly 2 and adapter 1 are fitted together and aligned, opening 1 3 corresponds with aperture 7.
  • the size and shape of the cross-section of channel 6, outlet 1 5 and opening 1 3 are equal and positioned such that when assembly 2 and adapter 1 are fitted together and aligned, channel 6 corresponds with outlet 1 5 and opening 1 3 (see Figure 3) . It will be appreciated that aperture 7 and channel 6 are on the same radial plane defined by the axis of rotation of assembly 2 about adapter 1 .
  • shaped flange 1 6 on assembly 2 is sized to co-operate with flange 8 on adapter 1 .
  • Diametrically opposed portions 1 7 of shaped flange 1 6 have a retaining lips 1 8 extending radially inwards (see Figure 4) .
  • Portions 1 7 are able to move radially independent of the remainder of shaped flange 1 6 due to cuts 1 9.
  • the width of lips 1 8 is such that when assembly 2 and adapter 1 are fitted together, lips 1 8 snap over flange 8. To remove assembly 2 from adapter 1 outward pressure is applied to disengage lips 1 8 from flange 8.
  • a metering piston 3 is sized to be a movable snug-fit within metering cylinder 1 4 to form metering chamber 20. In use, graduations 21 on piston 3 provide the operator with information on the quantity of material in the chamber to be dispensed.
  • Figures 5 to 7 show the dispensing operation with dispenser 30.
  • Dispenser 30 comprises vessel 31 connected to metering device 32.
  • Figure 5 shows assembly 2, rotated to a position where aperture 7 coincides with opening 1 3 so that vessel 31 is in fluid communication with chamber 20.
  • Metering piston 3 is adjusted to define the capacity of chamber 20.
  • the dispenser 30 has been spatially orientated so that material flows from the vessel via aperture 7 and opening 1 3 into chamber 20.
  • the assembly is rotated so that outlet 1 5 and opening 1 3 on assembly 2 are aligned with channel 6 in adapter 1 to define a passageway through which the metered amount of material is dispensed.

Abstract

L'invention porte sur un distributeur manuel destiné à doser une substance fluide telle que des granulés ou de la poudre. Ce distributeur comprend un réceptacle auquel est fixé un ensemble qui tourne autour du réceptacle entre des première et seconde positions. L'ensemble possède un orifice de distribution et une chambre de dosage. Dans la première position, la chambre de dosage est en communication fluidique, par l'ouverture, avec le réceptacle, mais pas avec l'orifice de distribution. Dans la seconde position, la chambre de dosage est en communication fluidique avec l'orifice de distribution, mais pas avec le réceptacle. La partie du réceptacle qui se fixe à l'assemble est conçue de façon à former un canal de sorte que, lorsque l'ensemble est fixé au réceptacle et adopte la seconde position, le canal et l'ensemble forment un passage qui relie l'orifice de distribution à la chambre. L'ouverture est positionnée pratiquement sur le même plan radial que le canal.
