Definitions
- the present invention relates to paste dispensers, and more particularly to hand-held paste dispensers of the type having a container and a discharge means for discharging paste from the container.
- paste is intended to cover any type of fluid having a relatively high viscosity such as cream, ointment, dentifrice or gel.
- paste dispensers of this type may be represented by those described in United Kingdom Patent Specification Nos. 2,070,922A (Lingner and Fischer) and 2,207,640A (Mansfield).
- the discharge means is of the type having a piston driven by a hand-operated spindle.
- the knurled knob could be rotated accidentally resulting in the discharge of toothpaste. It appears that this is both unhygienic and would block ducts in the toothbrush head by hardening of accidentally discharged dentrifice. We believe that these are the primary reasons why reservoir toothbrushes have not gained widespread usage. It is also desirable in many circumstances to prevent young children from dispensing paste that may be harmful to them, and thus presently available paste dispensers are unsuitable.
- the present invention is directed towards providing a hand-held paste dispenser to overcome these problems.
- a hand-held paste dispenser comprising:- a paste container having a discharge outlet; a discharge means mounted within the container for discharging paste from the container through the discharge outlet; and actuating means for the discharge means comprising a cap for the discharge outlet, the cap being releasably mountable to the container.
- the dispenser is tamper-proof for young children and paste will not be accidentally discharged, thus avoiding blocking of the discharge outlet and lack of cleanliness.
- the discharge means comprises a piston mounted within the container and driven by a rotating drive member, and wherein said cap includes means for engaging said drive member for rotation thereof to discharge paste from the container through the discharge outlet.
- the cap includes a male key or a female recess and the drive member includes the other of the male key or female recess for engagement of the cap and the drive member.
- the cap includes a key for engagement with a recess in the drive member.
- said means for engaging the cap and the drive member is effective for one direction of rotation only.
- said recess extends in a radial direction from a longitudinal axis of the drive member and includes a stop surface on one side thereof and a sloping surface on the other side to allow engagement for rotation of the drive member only in a direction for causing discharge of paste from the container.
- the dispenser includes metering means for indicating the quantity of paste discharged.
- said metering means preferably comprises stop means retractably engageable with said discharge means or said actuating means to limit movement of said piston for any one use of the dispenser.
- said stop means is mounted on the container for limiting rotation of said cap.
- the container and the cap include in one or the other thereof an inter-engaging recess, and a projection in the other thereof, rotation of the cap being limited by movement of the projection within the recess.
- said metering means includes graduation markings on the container for indicating the extent of rotation of said cap. This allows precise user control, which is important in some situations.
- the paste dispenser further comprises an applicator head for application of paste discharged through the discharge outlet.
- the applicator head preferably includes bristles to form a toothbrush head having a duct for delivery of paste from the discharge outlet to the bristles.
- the dispenser forms a reservoir toothbrush with all of the above-mentioned advantages.
- the container and the discharge means form a cartridge for releasable connection with the applicator head.
- the cartridge and applicator head include interengageable bayonet type fittings for releasable connection.
- the duct is preferably arranged to discharge dentrifice transversely of the bristles.
- the toothbrush head includes radially arranged bristles and a plurality of radially arranged duct openings for interproximal teeth cleaning.
- This toothbrush head is particularly effective for interproximal cleaning.
- a hand-held paste dispenser comprising:- a paste container having a discharge outlet; a discharge means having a user-operated drive member; and metering means for indicating the extent of movement of the drive member to allow user control of the quantity of paste discharged.
- the invention is suitable where paste is expensive or where it is important that dispensed quantities are known.
- the term "piston” is intended to cover any member actuated to urge paste from a container.
- the paste dispenser 1 comprises a substantially rigid tubular container 2 housing a discharge means 3 for discharge of paste from the container through a discharge outlet 4, adjacent which the container 2 is tapered.
- the dispenser 1 also includes a cap 5 for surrounding the discharge outlet 4.
- the discharge means 3 comprises a piston 6 which fits neatly within the container 2 and is mounted on an axially disposed threaded spindle 7 forming a drive member which is integral with a rotatable base 9 for the container 2.
- the exterior surface of the rotatable base 9 includes three radially extending recesses 10, each of which is bounded by a stop surface 11 on one side and a rearwardly and upwardly sloping surface 12 on the other side.
- the recesses 10 are for female engagement with an actuating key 13 forming an integral part of the cap 5.
- metering means for the paste dispenser comprises a band 15 surrounding the container 2 and having an elongate recess 16 for retractable engagement with a projection 17 on the cap 5 when the cap is pushed over the rear of the dispenser for discharge of paste.
- the band 15 also includes a slot 18 for reception of the projection 17 when the dispenser 1 is not in use and the cap 5 is over the front end surrounding the discharge outlet 4.
- the cap 5 When it is desired to use the paste dispenser 1, the cap 5 is removed from the front end and pushed over the rear end until the projection 17 engages the recess 16 at the anti-clockwise extremity thereof. In this position, the key 13 engages one of the recesses 10 in the rotatable base 9. Rotation of the cap 5 in the clockwise direction will rotate the rotatable base 9 by engagement between the key 13 and the respective stop surface 11 to effect longitudinal movement of the piston 6 mounted on the threaded spindle 7. This movement will urge paste out of the discharge outlet 4. Rotation of the rotatable base 9 will only be effected when the key 13 is rotated against the stops 11 and not against the sloping surfaces 12 so that rotation in one direction only, namely, that for discharge of paste is permitted.
- paste dispenser is simple to manufacture as there are relatively few parts.
- the paste dispenser of the invention allows dispensing of a metered quantity of paste in a relatively simple manner. This is very important where the paste is relatively expensive and it is important to avoid waste or where excessive discharge may be harmful.
- the dispenser 20 comprises a tubular container 21 having a curved front end leading to a transverse discharge outlet 23.
- a band 24 surrounding the container 21 includes a recess 25 and graduation marks 26 adjacent the recess 25 for indicating the quantity of paste discharged according to alignment with a line 27 on a projection 28 of a cap 29.
- transverse discharge outlet 23 may be suitable in certain situations.
- the container 21 is shorter and has a larger diameter then the container 2. Indeed, it is envisaged that many different shapes and sizes may be used, depending on the circumstances. For example, a wider diameter would be suitable for children having a "palm grip".
- the paste dispenser 30 is in the form of a reservoir toothbrush and parts similar to those described with reference to the previous drawings are identified by the same reference numerals.
- the dispenser 30 comprises a tubular container 31 onto which is mounted a paste applicator head, in this case a toothbrush head 32.
- the container 31 has a discharge outlet 33 communicating with a longitudinal duct 34 in the toothbrush head 32.
- the duct 34 has an opening 35 disposed transversely of bristles 36 mounted on the toothbrush head 32.
- the toothbrush head 32 connects with the container 31 by way of a bayonet fitting having a slot 37 in the container 2 and a key 38 on the toothbrush head 32.
- the container 31 thus forms a removable dentifrice cartridge and the connection is relatively easily made by the bayonet fitting.
- a cap 39 is provided for the brush head 32 which incorporates a double-skin venting arrangement 40, which helps to maintain hygiene of the bristles 36 by allowing ventilation while preventing water escape after washing.
- the invention overcomes the problem of accidental discharge of dentifrice which has heretofore caused blocking of the discharge ducts and is not hygienic. We believe that this is one of the major reasons why reservoir toothbrushes have not gained wide usage despite being available for many years. What the invention provides is a reservoir toothbrush which is simple to use, is hygienic in operation and which prevents clogging of ducts. Further, the reservoir toothbrush illustrated will prevent excessive discharge of dentifrice at any one use. This is important for cleaning of children's teeth because fluoride in dentifrice may be harmful and further , waste of dentifrice for adult use is avoided.
- FIG. 7 there is illustrated an intermediate fixture for the paste dispenser 30, indicated generally by the reference numeral 50.
- the intermediate fixture 50 includes a stem 51 having a narrow end portion 52 arranged for a force-fit within an applicator head such as a brush head.
- a brush head 53 having a conventional bristle arrangement is illustrated.
- FIGs. 8(a) and 8(b) there is illustrated an interproximal brush head 54 which would be very useful in certain situations.
- the interproximal brush head 54 includes radially arranged discharge ducts 55 which discharge onto radially arranged bristles 56.
- the dispenser of the invention may form a dentifrice container for use with either a conventional toothbrush or a brush head which is secured to the dispenser after the dentifrice has been dispensed on to the bristles.
- the rotatable base may itself be retractably engageable with a stop which limits rotation thereof to provide for a metered quantity discharge of paste.
