Abstract

A container (10) for a dispenser (100) has a reservoir (12) containing soap in the form of a stiff gel (14). In a neck portion (16) of the container (10) there is located a resilient tube (18) which is retained in position by shoulders integrally formed on the neck portion (16). With the tube (18) in its open condition, gel (14) can pass from the reservoir (12) into the tube (18) and is retained therein by virtue of the outlet (22) being normally closed. When a push button mechanism (114) is operated, the tube (18) is deformed to a closed condition so as to force the gel (14) therein outwardly through the lower end and consequently through the outlet (22). Thereafter the resilience of the tube (18) re-opens the passage for gel (14) from the reservoir (12) into the neck portion (16).

Description

Containers and Dispensers for the Contents thereof
This invention relates to containers, and
dispensers for using such containers to dispense the contents thereof.
In wash rooms and public lavatories, it is
convenient to use soap which can be dispensed from dispensers mounted on the wall. The soap is available as a relatively stiff gel and can be supplied in plastic bags which are hung inside the dispenser with a suitable mechanism such as a lever or a button being used to dispense the gel.
The necks of the containers have to be reinforced so that pressure can be applied to dispense the gel from the outlet. The stiffness of the gels, however, makes them difficult to use because they do not flow very easily and tend to resist movement from the reservoir into the neck of the collar. Also additives in the gels can make it difficult to dispense through conventional dispensers because of wear.
It is an object of the invention to provide a container which obviates and/or mitigates the above mentioned disadvantages.
According to a first, aspect of this invention there is provided a container comprising a reservoir adapted to receive a material to be dispensed, an outlet portion in communication with the reservoir, and conduit means associated with the outlet portion, the conduit means being resiliently deformable between an open position, providing a passage in the outlet portion into which material can pass from the reservoir, to a closed position providing for dispensing of material from the outlet portion of the container.
Preferably, the conduit means comprises a tube disposed with the outlet portion and, desirably, the container comprises retaining means to hold the tube in the outlet portion. The outlet portion may have the form of a neck portion, the retaining means comprising formations provided on the neck portion and engaging with the tube. The formations may include shoulders on an inner region of the neck portion which engage a corresponding shoulder on the tube thereby to prevent the tube from moving into the reservoir. The formations may include stops at an outer region of the neck portion which engage an outer end of the tube.
The conduit means may be formed from an elastic material, preferably rubber.
Alternatively the conduit means may comprise a sleeve attached to the outlet portion externally thereof. The sleeve may be formed from an elastic material, preferably rubber.
Conveniently, the container is provided with support means to enable the container to be supported in a dispenser. The support means may comprise apertures provided either in the reservoir or on tags attached to the reservoir.
According to a second aspect of the invention, there is provided a dispenser for use with a container as described in any of the six preceding paragraphs, the dispenser comprising holding means for holding the container in an orientation so that material therein can be dispensed, force applying means for applying a force to the outlet portion of the container whereby to deform the conduit means to the closed position and to push material in the outlet portion towards a free end region thereof, and sealing means movable from a sealing position for sealing said free end region to prevent leakage of the material therefrom, to a non-sealing position in which the material in the outlet portion can be dispensed, the sealing means being so formed that when said force is applied to the outlet portion, the sealing means is moved to the non-sealing position so that material can be dispensed.
Preferably the sealing means is normally biassed towards the sealing position. The biassing means may be in the form of a spring member, preferably a leaf spring.
The holding means may comprise hook members adapted to hook into apertures provided in the container.
The force applying means may comprise a push button mechanism. The push button mechanism may comprise a first member retractable within a second member, and spring means acting between the first member and the second member. With this arrangement, when the push button mechanism is pushed towards the outlet portion, the first member deforms the conduit means to the closed position, and further pushing of the push button
mechanism moves the second member over the first member until the second member engages the outlet portion to deform further the conduit means so that material in the neck portion is pushed towards the free end region thereof.
An embodiment of the invention will now be
descri bed by way of example only, with reference to the a cc omp any i n g drawings, in which:-
Fig. 1 is a schematic plan view of a container according to the invention;
Fig. 2 is a view along the line I I - I I of Fig. 1; and
Fig. 3 is a view of a container as shown in Fig. 2 which has been installed in a dispenser.
In the drawings, a container generally designated 10 is shown which comprises a reservoir 12 containing a material to be dispensed which, in the embodiment shown, is a soap in the form of a stiff gel 14. The container 10 also comprises a neck portion 16 of reduced width. The container 10 is formed from two sheets of plastics material known in the art which are fused together along a boundary 24 except for an outlet 22 on the outer edge of the neck portion 16.
A tube 18 is disposed within the neck portion 16 and is formed of an elastic material, e.g. rubber. The tube 18 comprises two parts 18a, 18b of different diameters, the smaller diameter part 18a facing the reservoir 12 to define an inwardly facing shoulder. As can be seen from Fig. 1, in the region where the
reservoir 12 and the neck portion 16 meet, the boundary 24 has the form of shoulders 26 which are adapted to cooperate with the shoulder 28 on the collar 18 to prevent the tube 18 from moving into the reservoir 12.
The tube 18 is resiliently deformable between an open position as shown in the drawings and a closed position in which opposite sides of the tube 18 are pressed together. In the open position, the tube 18 defines a conduit 20 for the passage of the gel 14 from the reservoir to the outlet 22.
The boundary 24 has the form of steps 30 at the outer end region of the neck portion 16 adapted to engage an outer end 32 of the tube 18. In this way, the tube is prevented from being forced out of the container via the neck portion 16.
Tags 34 are attached to the top of the container 10. The tags 34 are provided with apertures 36 for receiving hooks in a dispenser as will be explained below.
Fig. 3 shows a container 10 installed in a
dispenser 100. The dispenser 100 comprises a housing 110 in which are mounted two hooks 112 on a back plate, only one of which is shown in Fig. 3 for clarity. The hooks 112 pass through the apertures 36 in the tags 34, to suspend the container from the back plate. The dispenser 100 has a push button mechanism 114 which comprises a first member in the form of a substantially rectangular bar 116 and a second member in the form of a button 118. The button 118 is provided with a recess 120 into which the bar 116 can retract. A spring 122 is also provided in the recess 120 and acts between the bar 116 and the button 118 to urge the bar 116 out of the recess 120 and towards the neck portion 16 of the container 10 as shown. If the push button mechanism 114 is pushed in the direction indicated by the arrow A, then the bar 116 will engage the neck portion 16 of the container 10, and continued pushing will result in the bar 116 pressing the sides of the tube 18 at an upper region thereof against each other, effectively closin g t h e t u b e 1 8 .
By continuing to push the push button mechanism 114 in the direction indicated by the arrow A, the button 118 will move over the bar 116 until the button 118 engages the neck portion 16. It will be appreciated that the spring 122 is of sufficient strength to enable the bar 116 to push the sides of the tube 18 against each other, but is not so strong that it will prevent the button 118 from being pushed against the neck portion 16. If the push button mechanism 114 is then pushed further in the direction indicated by the arrow A, the sides of the tube 18 at a lower region thereof will also be pressed together. In view of the fact that upper regions of the sides of the tube 18 have already been pushed together, then pushing the sides of the lower region of the tube together will result in all the gel 14 which is inside the tube 18 being pushed in a downward direction towards the outlet 22 of the
container 10.
A leaf spring 124 is mounted on a lower portion of the housing 110. An end 126 of the leaf spring 124 engages the lower region of the neck portion 16 at the outlet 22. The spring 124 urges the lower end region against an abutment 128 of the housing 110. In this way, the leaf spring 124 normally seals the outlet 22 of the neck portion 16 to prevent leakage of the gel 14 out of the opening 22. The leaf spring 124 is formed such that it can prevent leakage of the gel 14, but, when the push button mechanism 114 is depressed to push the gel 14 dowardly towards the opening 22, the force applied by the gel 14 is sufficient to push the spring 124 away from its sealing position to a non-sealing position to open the opening 22 and allow the gel 14 to be dispensed from the container 10.
When the containers are supplied for use, the opening 22 is sealed by a strip of the plastics material from which the container is made. In this respect, reference is made to Fig. 1 in which the strip of plastics material is shown in phantom and is designated 200. When it is desired to use the container 10, it is installed in a dispenser 100 and the bottom portion 200 of the plastics material is then torn or cut away.
Thus, the embodiment of the container described above has the advantage that problems associated with the stiffness of the gels and their resulting lack of fluidity are obviated. In particular, the use of the tube 18 enables the gel to pass into the neck portion relatively easily.
In an alternative embodiment of the container (not shown), a resilient sleeve is attached externally of the neck portion to surround same. The sleeve is resiliently deformable between an open position, retaining the walls of the neck portion in a spaced relation to allow passage of gel into the neck portion, and a closed position, effectively closing the neck portion to dispense gel therefrom. The external sleeve may be formed from an elastic material, such as rubber.
It is to be appreciated that the use of the dispenser is not restricted to soap. For example, the dispenser can be used for other products such as jam, sauce etc. Various modifications can be made without departing from the scope of the invention; for example, instead of the tags 34, the apertures 36 could be formed directly through the reservoir 12 and then the plastics material could be sealed to prevent the leakage of the material 14. A pull lever mechanism may be used as an alternative to the push button mechanism.
