Definitions

  • the present invention relates to a viscous liquid dispenser which permits a measuring of the liquid to be dispensed.
  • the invention relates further to a viscous liquid dispenser of the squeeze-bottle type or of the attachment type .
  • viscous liquids are often difficult and messy to measure for dispensation, since the liquid is difficult to pour into a measuring cup and slow to remove from the measuring cup. It is therefore desirable to have a container which is able to dispense a measured quantity, so that the use of a measuring cup or the like is avoided.
  • Some of the viscous liquids which are advantageously dispensed from a container capable of measuring are: liquid detergent, shampoo, oil, syrup and honey.
  • An object of the invention is to provide a viscous liquid dispenser which can be used to measure and dispense a quantity of viscous liquid.
  • Another object of the invention is to provide a viscous liquid dispenser which can be used to measure a variable quantity of viscous liquid.
  • a further object of the invention is to provide a viscous liquid dispenser which can be inexpensively made from one integral moulded piece.
  • viscous liquid dispenser comprising a reservoir for holding the liquid, at least a part of the reservoir being resiliently squeezable, characterized in that the dispenser comprises: a substantially vertical measuring channel having a cross- section suited to allow a bubble of air in the liquid to move along the channel with a flow of the liquid therein, the bubble in the channel for measuring a quantity of the liquid to be dispensed; a spout in communication with an upper part of the channel; and air trap means including an air chamber and passage means, a lower end of the channel being in communication with one side of the chamber, and the passage means communicating an opposite side of the chamber with the reservoir.
  • the flow of the liquid through the passage means to the lower end of the channel across the chamber from the opposite side to the one side is able in use to release the air bubble from the chamber into the lower end and, upon releasing the reservoir, to replenish the chamber with air drawn back through the spout, channel and air trap means to the reservoir.
  • a dispenser for dispensing a viscous liquid the dispenser to be connected with a reservoir for holding the liquid, at least a part of the reservoir being resiliently squeezable, the dispenser charaterized in that it comprises: a substantially vertical measuring channel having a cross- section suited to allow a bubble of air in the liquid to move along the channel with a flow of the liquid therein, the bubble in the channel for measuring a quantity of the liquid to be dispensed; a spout in communication with an upper part of the channel; and air trap means including an air chamber and passage means, a lower end of the channel being in communication with one side of the chamber, and the passage means communicating an opposite side of the chamber with the reservoir.
  • Fig. 1 is a perspective view of a squeeze-bottle dispenser according to the preferred embodiment
  • Fig. 2 is a side view of the dispenser of Fig. 1;
  • Fig. 3 is a hozizontal cross-section of the squeeze- bottle of Fig. 1 about line A;
  • Fig. 4 is a hozizontal cross-section of the squeeze- bottle of Fig. 1 about line B; and Fig. 5 is a hozizontal cross-section of the squeeze- bottle of Fig. 1 about line C.
  • the dispenser (1) is used as a honey dispenser for dispensing a desired quantity of honey into a beverage such as tea or coffee.
  • the dispenser (1) is a one piece, blow moulded, translucid, squeezable plastic bottle.
  • Channel (2) is provided outside reservoir (3).
  • Dispenser (1) is made from thermoplastic material such as polyethylene or polypropylene, by blow molding techniques in which an extruded parison is blown into the general shape of the bottle.
  • the wall thickness of the dispenser (1) is such that the walls are flexible while retaining the fabricated shape of the dispenser (1). As shown in Figs.
  • the dispenser (1) has a reservoir (3), a channel (2) extending along a front vertical side, a spout (8) in communication with a top part of channel (2), a bottom inlet (4) of channel (2), and an air chamber (6).
  • Dispenser (1) is provided with an opening covered and sealed by screw-cap (14) for filling reservoir 3, and channel (2) is provided with graduation marks or lines (12) to serve as indicating means for measuring a level of a bubble therein.
  • Spout (8) can be covered by cap (9).
  • channel (2) is formed to go around chamber (6) toward the center of reservoir (3).
  • Chamber (6), inlet (4), shelf (10) and passage means (11) form air trap means in communication between lower part (4) of channel (2) and reservoir (3).
  • Passage means (11) are defined by the walls of bottle (1) and shelf (10), and the passage means (11) provide a flow path between reservoir (3) across chamber (6) to lower part (4).
  • Fig. 3 shows the horizontal cross-section of the essentially ellipsoid shaped reservoir (3) and the essentially square shaped horizontal cross section of channel ( 2 ) .
  • Fig. 4 shows the horizontal cross-section of dispenser (1) and air trap means including air chamber (6) and inlet (4).
  • Fig. 5 shows the horizontal cross-section of dispenser (1) along the line of shelf (10) of the passage means (11) interconnecting reservoir (3) with the air trap means.
  • shelf (10) extends from the left side wall of inlet (4) to a position under chamber (6).
  • the position of the right side of shelf (10) is such that flow through passage means 11 rises into chamber (6) at the right side thereof so that an air bubble is thereby pushed down and out from the left side of chamber and into inlet (4).
  • a measured quantity may be dispensed as follows:
  • bottle (1) is squeezed until the level of honey in channel (2) reaches the top of channel (2) and begins to enter spout (8).
  • bottle (1) is tilted from vertical as if to pour the honey from spout (8), placed over the beverage where the honey is desired, and further pressure is applied to the bottle (1) to begin dispensing the liquid.
  • An air bubble is released from chamber (6) into inlet (4) of channel (2).
  • a little more honey can be dispensed by squeezing a little more after the bubble is emitted from the spout (8) .
  • Quantities less than one teaspoon may be dispensed by stopping the squeezing before the bubble reaches the spout (8).
  • graduations (12) are provided on the transparent or translucid channel (2) so that squeezing may be stopped at a calibrated point such as one half teaspoon.
  • cap (9) shown in Fig. 2 is used as closure means to seal out air from channel (2), so that the honey stays fresh.
  • the bubble is released in the method described above by the action of the honey flow across the base of the chamber (6) as well as by tilting the dispenser (1) to pour the honey from spout (8). Although it is a bit slower, one may cause a bubble to be released from chamber (6) by tilting alone.
  • the chamber being also made of the same resilient material as the rest of the dispenser (1) may also be squeezed to release the bubble. Any one or any combination of the above mentioned three ways can be used to cause the air trap means to release the bubble.
  • the closure means could also include a suitable valve provided either in the spout (8) or channel (2).
  • the air chamber (6) can be located at other positions with respect to inlet 4.
  • the dispenser may also be an attachment unit to be attached to a separate replaceable reservoir (3).
  • the dispenser may also be an attachment unit to be attached to a separate replaceable reservoir (3).
  • dispenser (1) with two or more channels and air trap means.
  • Two channels and air trap means can be advantageous under certain conditions.
  • the exact dimensions of the height, and cross-sectional area of the channel, and the number of channels and air trap means, are parameters which can be determined.
  • the factors to be considered are the viscosity of the liquid, surface tension and the maximum desired quantity of liquid to be dispensed.
  • the pressure generating means must be able to expel enough liquid into the measuring channel (2) for measuring, then must expel the desired quantity out the spout (8).
  • reservoir (3) must be capable when squeezed to expel a maximum of a little more than twice the maximum desired quantity to be dispensed.
  • honey is dispensed for coffee or tea, and so reservoir (3) is preferably able to expel a little more than one teaspoon (ca. 5 mL) meaning that a little more than two teaspoons is suitable (ca. 10 mL).
  • the channel section should be dimensioned between 12mm by 12mm to 17rnm by 17mm and preferably 14mm by 14mm. If the channel dimensions are too large, it is then more possible that the viscous liquid can flow around the bubble thus making the measurement inaccurate. If the channel dimensions are too small then the viscous resistance becomes great and the required length of the channel to measure a substantial quantity becomes very long.

Abstract

On décrit un distributeur (1) de liquide visqueux, comprenant un réservoir (3) contenant le liquide (au moins une partie du réservoir (3) pouvant être comprimé de manière élastique), un canal de dosage (2) dans lequel est mesurée une certaine quantité du liquide devant être distribué, un bec (8) communiquant avec la partie supérieure du canal (2), ainsi qu'une poche à air comprenant une chambre à air (6) et un passage (11). Une extrémité inférieure (4) du canal (2) communique avec un côté de la chambre (6), et le passage fait communiquer le côté opposé de la chambre (6) avec le réservoir (3). Ainsi, lorsque l'on comprime le réservoir (3), le liquide s'écoule par le passage (11) vers l'extrémité inférieure du canal (2) en traversant la chambre (6) d'un côté à l'autre, ce qui permet de libérer la bulle d'air de la chambre (6) vers l'extrémité inférieure (4), et, lorsque le réservoir (3) est libéré, la chambre (6) est à nouveau remplie d'air aspiré par le bec (8), et qui passe à travers le canal (2) et la poche à air vers le réservoir (3).
