Abstract
A dispenser for toothpaste consists of a cylindrical housing 1 having a nozzle 3 and supported on a base in the form of a resiliently compressible cup 5. A rod 13, attached to the cup 5, extends towards the nozzle 3 and a piston 17 is slidable on the rod 13. The piston carries a steel star ring 21 which can grip the rod 13 and the wall of the housing 1.
Compression of the cup 5 causes the rod 13 to move the piston 17 towards the nozzle 3 thereby forcing paste through the nozzle 3, and relaxation of the compression allows the rod 13 to slide back through the piston 17 which in turn remains stationary within the housing 1. A regular amount of paste can be dispensed by each compression of the cup 5.
Description
- This invention relates to a dispenser for paste materials, such as cosmetic creams or toothpastes.
- Conventional toothpaste tubes suffer from a number of disadvantages. For example, they are aesthetically unpleasing and cause undesirable waste of. toothpaste which becomes trapped in the squeezed tube during use.
- Free-standing toothpaste dispensers are known, in which the paste is discharged from a nozzle by applying manual pressure to a discharge valve adjacent the nozzle. However, it has been found that paste material becomes trapped between the valve and the nozzle outlet, and that drying out of this excess paste tends to cause undesirable blockage of the nozzle.
- By means of the present invention it is possible to provide a free-standing dispenser which does not rely on a discharge valve for controlling the flow of paste material from the nozzle, and which thereby reduces the problem of blockage caused by drying out of the material.
- According to the present invention, there is provided a free-standing dispenser for paste material, comprising a housing for the material and an outlet orifice communicating with the housing, a piston axially movable in the housing towards the orifice and provided with restraining means to prevent axial movement in a direction away from the orifice, and a resilient, compressible member connected to the housing at the end thereof remote from the orifice and arranged so that compression of the member causes movement of the piston towards the orifice, thereby pumping paste material out of said orifice, and release of the compression on the member causes the piston to remain stationary relative to the adjacent walls of the housing.
- Preferably, the housing is generally cylindrical and is free-standing on a base which consists of or includes the compressible member. Paste material may be ejected from the orifice by applying hand pressure to the housing against the resilience of the compressible member.
- The compressible member may be a spring loaded pad, but preferably it comprises a resilient plastics cup having a flexible wall attached to the housing, the wall being deformable under the action of a compressible force.
- The piston may have a centrally located passage through which passses an elongate guide rod attached to the compressible member, and frictional engagement between the rod and piston is designed to prevent movement of the piston away from the orifice. In addition, frictional engagement between the piston and wall of the housing may be provided which prevents movement of the piston away from the orifice.
- In order to minimise wastage of paste material, the piston may be shaped to conform substantially to the internal shape of the upper end of the housing, so that when the piston reaches its uppermost position little paste material is trapped between the piston and housing.
- The housing and compressible member may, if desired, be encased in an outer shell, and the housing will suitably be a sliding frictional fit in the shell. This enables the dispenser to be used either freely in the hand or when standing on a horizontal surface, in addition to improving the aesthetic appeal of the dispenser.
- The invention is now described by way of example with reference to the accompanying drawings, in which:
- Figure 1 is a front elevation of a toothpaste dispenser.
- Figure 2 is a section along A-A of Figure 1, additionally showing a cover for the dispenser, and
- Figure 3 is a vertical section through an alternative embodiment of toothpaste dispenser.
- Referring to Figures 1 and 2 of the drawings, a toothpaste dispenser comprises a cylindrical plastics housing 1 having a
curved nozzle 3 and supported on a base in the form of aresilient plastics cup 5. Thecylindrical wall 7 of thecup 5 is curved inwardly and the rim of the wall is received in anannular groove 9 formed in the housing 1. - The base of the
cup 5 has asocket 11 in which aplastics rod 13 is located and retained therein by friction or by a suitable adhesive. The base of thecup 5 also has asmall passage 15 formed therein to permit the flow of air between the interior of the housing 1 and the exterior during use. - A
piston 17 is slidably mounted on therod 13, and consists of a plastics moulding 19 attached to asteel star ring 21. Themoulding 19 has a domedupper portion 23 and a pair of outwardly flaredcylindrical walls star ring 21 includes eight inclined, radially extendingtangs 27 spaced circumferentially and equidistantly around the ring and which are designed so as to bite into the inner wall of the, housing 1, when thepiston 17 is forced towards the base of the housing thereby preventing downward movement of the piston. When thepiston 17 is forced towards thenozzle 3, thetangs 27 can bend slightly downwardly to reduce the diameter of the circle circumscribing the tangs and hence permit thepiston 17 to move up the housing. - The
ring 21 also includes four inwardly directed,inclined tangs 29 which are spaced circumferentially around therod 13. Thetangs 29 grip therod 13 and when the rod is pushed towards thenozzle 3 the grip increases due to the reduced inclination of the tangs and thepiston 17 is thereby carried up the housing 1 by a distance equal to the longitudinal movement of the rod. When therod 13 is moved in the opposite direction, the gap between thetangs 29 opens slightly to permit unobstructed movement of therod 13 through the piston. - It will be appreciated that repeated upward movement of the
rod 13 will cause thepiston 17 to climb gradually up the housing 1 towards thenozzle 3. - Attached to the
nozzle 3 is a projectingshoulder 31 which can receive downward pressure from a thumb or finger during operation of the dispenser. The dispenser is also provided with acap 33 which clips over thenozzle 3 and helps to prevent the contents of the dispenser from drying out. - Referring to Figure 3 of the drawings, where like reference numbers have the same significance as in Figures 1 and 2, the housing 1 is slidably mounted in an
outer cylinder shell 35, which also includes an internalannular groove 37 at its lower end to receive an annular locatingrib 39 on thecup 5. Theshell 35 is provided with ashoulder 41 to receive and locate thecap 33 on the dispenser. - In order to dispense paste material, it is necessary merely to apply downward manual pressure on the housing 1 against the resilience of the
cup 5. This pressure causes theflexible wall 7 to bend inwardly, thereby permitting therod 13 to move upwardly relative to thenozzle 3 and to carry thepiston 17 towards the nozzle. The piston thus forces paste material out of thenozzle 3, the amount of material being determined by the degree of compression of thecup 5 and hence the distance travelled by thepiston 17. On relaxing the pressure on thecup 5, theflexible wall 7 regains its original shape and therod 13 moves downwardly relative to the nozzle while thepiston 17 remains stationary relative to thenozzle 3. The net effect is that the piston will travel up therod 13 by a distance equal to the longitudinal distance of compression of thecup 5. - It will be appreciated that the
cup 5 can be replaced by other types of spring loaded devices which will function in a similar manner.
