GB2493979A - Dispenser tube comprising piston on threaded shaft - Google Patents

Abstract

A dispenser comprises: a tube 10, a threaded shaft 40 and a piston 70. The piston engages with the threads of the shaft which rotates relative to the tube to move the piston axially and move items 50 towards the tubes opening. The each item can be dispensed by a single rotation of the shaft, a fraction thereof, or less. Ideally the items are annular sweets 50 through which the threaded shaft 40 passes. Preferably the piston is prevented from rotating with the shaft by longitudinal cooperating fins and rails projecting in from the tube. The items could be retained in the tube by grips 90. The shaft may be provided with an integral or separable knob 30 shaped like the items being dispensed to rotate it. The tube could be airtight sealed by lid 20 which engages the shaft. There may be a transparent or translucent region of the tube for determining the fill level. The device can function in a similar manner to a glue stick. There is a special loader to move grips 90 aside.

Description

Dispenser This invention relates to a dispenser, particularly for the dispensing of one of a plurality of items. The invention is especially relevant to the dispensing of small annular items, such as certain types of confectionary.

Tube-based dispensers incorporating screw threads and twist actions are known.

However, these are usually concerned with the dispensing of extrudable solids, such as lipstick, glue and skincare products. Such dispensers typically comprise a twin-tube mechanism in which the solid material is contained within an inner tube mounted within a surrounding outer tube. This results in a dispenser which is relatively complicated and therefore both difficult and expensive to manufacture.

Further expense results from such dispensers being inefficient in their use of space; only a small proportion of the volume of such dispensers is taken up by their contents.

Dispensers for confectionary such as Fez and Kraft Lifesavers, the US equivalent of Polo mints, typically use a spring mechanism to raise the products within a tube. Such dispensers suffer from some of the same drawbacks as the twist-action extrudable solids dispensers as well as being difficult to recycle.

Confectionary dispensers -especially if they are easily-recognisable and have a tactile quality -may, as in the case of the Pez dispensers, in time acquire iconic status, strengthening brand awareness and becoming collectible.

Simple tube-like containers or dispensers allow the contents to spill when tilted or inverted. Such dispensers may also allow contamination of the contents, particularly where fingers or hands are inserted to pick and remove an item.

They may also fail to provide effective airtight or semi-airtight seals.

There is therefore a need for a new type of dispenser which is distinctive in its operation and also which addresses at least some of the problems with existing dispensers outlined above.

According to an aspect of the invention there is provided a dispenser for dispensing a plurality of items, comprising: a tube, for containing the plurality of items; a threaded shaft, rotatably mounted within the tube; a pusher, for pushing items along the tube, threadably engaged with the shaft; the tube, shaft and pusher being arranged such that rotation of the shaft relative to the tube advances the pusher within the tube; and wherein the thread of the shaft is adapted such that a turn of 3600 or less of the shaft within the tube advances the pusher by an amount sufficient to result in the dispensing of one of the plurality of items.

By providing such a dispenser, the storing of items and the dispensing of items individually can be achieved efficiently -and, where relevant, hygienically.

The arrangement whereby items are dispensed by means of the advance of a pusher threadably engaged with a shaft may allow for the dispenser to be self-contained and of fixed exterior dimensions.

Preferably, the turn or partial rotation is of less than 100, 20°, 330 450, 90°. 120°, 180°, 240° or 270°. This may allow for ease of use; the user may be able to dispense an item in a single action.

Preferably, the pusher comprises a thread of complementary pitch or calibration to that of the shaft.

Preferably, the dispenser further comprises means for restraining rotation of the pusher within the tube as the shaft is turned. The means for restraining may comprise a restraining feature of the pusher adapted to interact with a complementary restraining feature of the tube.

Preventing rotation of the pusher may prevent otherwise concomitant rotation of the pusher and the items being dispensed as the shaft is turned.

Preferably, the restraining feature of the pusher comprises at least one fin arranged about the pusher axis. Preferably, the restraining feature of the pusher comprises an arrangement of fins about the pusher axis. The arrangement of fins about the pusher axis may be equiangular. The use of fins may save weight and reduce material use; an equiangular distribution of fins may reduce the amount of rotation required before the pusher is prevented from rotating further.

Preferably, the restraining feature of the tube comprises a longitudinal rail arranged parallel to the axis of and along the inner surface of the tube. The rail may be integral to the tube.

Preferably, the dispenser further comprises means for providing rotation feedback to a user of the dispenser. Those may be formations located on at least one of the tube, shaft or pusher, adapted to interact with adjacent features of at least one of the tube, shaft, pusher or items to be dispensed. The rotation feedback may comprise an audible click.

Preferably, the dispenser further comprises a plurality of resistance grips -or "tangs" -adapted to provide a resistance force to items being dispensed from the tube. The resistance grips may be adapted to provide a supportive force sufficient to maintain items in the tube irrespective of the orientation of the tube. This may prevent spillage of the items from the dispenser. The resistance grips may comprise resilient flaps, prongs or other form of projecting feature.

The resistance grips may be located at the dispensing end of the dispenser tube.

In some embodiments the resistance grips protrude beyond the end of the dispenser tube and may be adapted to support at least one item to be dispensed at a position beyond the end of the dispenser tube; the resistance grips may be adapted to enable a user of the dispenser to dispense an item without needing to touch a subsequent item to be dispensed.

The resistance grips may be connected to the dispenser tube, preferably being adapted to engage with at least one outer circumferential feature of an item to be dispensed. Alternatively, the resistance grips may be connected to the threaded shaft, preferably being adapted to engage with at least one inner circumferential feature of an item to be dispensed.

In other embodiments the resistance grips are recessed within the end of the dispenser tube.

Preferably, the dispenser further comprises a twist grip connected to the threaded shaft. The twist grip may be detachable from the threaded shaft. In some embodiments the twist grip is connected to the threaded shaft by means of one of a snap-fit, screw-fit or locking connection. In other embodiments the twist grip and threaded shaft are integral.

Preferably, the twist grip further comprises a gripping element around its circumference. This gripping element may comprise at least one of a knurled, roughened or angular surface. The twist grip may be representative of the items to be dispensed.

Preferably, the dispenser further comprises a cap adapted to seal the dispensing end of the dispenser tube. The cap may comprise a chuck key adapted to engage with the shaft.

Preferably, the dispenser is adapted to be substantially airtight. This may allow for the storage in the dispenser of items which might otherwise contaminate their surroundings by smell and/or other emissions. This may also allow for the storage of items which might otherwise become contaminated by their surroundings.

Preferably, the shaft has a hollow centre. more preferably, the shaft comprises an open-ended tube.

Preferably, at least two of the tube, shaft or pusher are manufactured from the same material. The material may be biodegradable and/or edible.

Preferably, the dispenser is adapted to dispense items of a depth (or height) of less than 10 mm, between 3 mm and 8 mm, preferably between 4 mm and 6 mm, more preferably approximately 5 mm.

Preferably, part of the tube is adapted to allow the fill level of the tube to be determined. Part of the tube may be made of a translucent or transparent material.

Preferably, the items to be dispensed are annular.

The items to be dispensed may be foodstuffs, preferably confectionary.

Alternatively, the items to be dispensed may comprise one or more of: pharmaceuticals (such as tablets), medical supplies (such as bandage rolls), construction materials (such as nuts or washers), and manufacturing assembly components (such as induction coils and ferrite rings).

According to another aspect of the invention there is provided a loaded dispenser comprising: a dispenser as described herein; and a plurality of items to be dispensed; wherein the items are annular and arranged in a stack on the threaded shaft.

According to a further aspect of the invention there is provided a device for loading the dispenser described herein with a plurality of items for dispensing, the device comprising: means for displacing the resistance grips; means for returning the pusher to its starting position on the threaded shaft; and means for loading the plurality of items into the tube.

According to a further aspect of the invention there is provided a dispenser for dispensing a plurality of items, comprising: a threaded shaft; a pusher, for pushing the items, threadably engaged with the shaft; the shaft and pusher being arranged such that relative rotation by 360° or less of the shaft and pusher advances the pusher by an amount sufficient to result in the dispensing of one of the plurality of items.

Generally, the dispenser is a hand-powered mechanical device for dispensing solid objects featuring cross-sectional internal voids, and embodiments have some or all of the following features: * A threaded shaft or spine utilising and occupying the cross-sectional voids of the products being dispensed * A threaded shaft or spine incorporating a hollow axial tube * Caps or twist grips designed as analogues of the products being dispensed.

* The dispensing mechanism makes efficient use of product volume by occupying and utilising the void integral to the contents * The cap and twist grip are shaped to mimic the dispenser's contents (facilitating strong branding) * Resistance grips control the release of each dispensed item (preventing spillages, improving hygiene and enabling easy removal of each item by the user) * An integral hole' is visible through the central axis of the mechanism (facilitating strong branding) * A single material is used for all components (enabling easy recycling) * Airtight or semi-airtight seals are used throughout (ensuring the longevity of perishable goods) Typically, the dispenser offers at least some of the following advantages: * Robustness * Ease of use * Hygienic * Aesthetically pleasing * Smelltight' I substantially or semi-airtight * Easily recyclable * Inexpensive to manufacture The dispenser is ideally suited to solid products featuring cross-sectional voids, for example confectionary such as Rowntree's Polo mints or Kraft Lifesavers (generally, mint flavoured compressed confectionery); foodstuffs such as baked bagels or ring doughnuts; but also other annular items, for example, threaded nuts, washers, induction coils and ferrite rings as used in construction or manufacturing, pharmaceuticals (such as tablets), medical supplies (such as bandage rolls) and many other items.

A smell-tight' or substantially airtight dispenser as herein described may overcome a disadvantage of traditional foil-wrappings (as used, for example, for mint packets) -namely that once opened, the contents (eg. mints) may impair the smell and/or flavour of adjacent objects.

The dispenser may be tailored and branded for use with particular products, such asPolos.

In order to facilitate recycling, reduce waste and to enable efflcient packaging, transportation and storage, the following should also be minimised: * The range of materials used for components (typically a single material may be used) * Unit mass * Unit volume The invention extends to methods and/or apparatus substantially as herein described with reference to the accompanying drawings.

Any apparatus feature as described herein may also be provided as a method feature, and vice versa. As used herein, means plus function features may be expressed alternatively in terms of their corresponding structure.

Any feature in one aspect of the invention may be applied to other aspects of the invention, in any appropriate combination. In particular, method aspects may be applied to apparatus aspects, and vice versa.

These and other aspects of the present invention will become apparent from the following exemplary embodiments that are described with reference to the following figures in which: Figure 1 shows an exterior view of a dispenser; Figure 2 shows a cutaway view of the dispenser of Figure 1; Figure 3 shows the dispenser in side elevation and cross-section; Figure 4 shows the cap of the dispenser; Figure 5 shows the threaded shaft or spine and twist grip of the dispenser; Figure 6 shows the pusher or pusher nut; Figure 7 shows detail of the loaded dispenser; and Figure 8 shows the resistance grips.

Overview Figure 1 shows a dispenser 1 comprising a tube 10 with a sealing cap 20 at one end and a twist-action grip 30 at the other end. The dispenser comprises a central threaded spine 40 which in this embodiment has a hollow core which results in a central void 80 extending along the length of the main or longitudinal axis of the tube 10.

Figure 2 shows a cutaway view of the dispenser; Figure 3 shows the dispenser in side elevation and cross-section. The dispenser typically contains five main components: * Tube 10 * Cap2O * Twist grip 30 * Threaded shaft or spine 40 * Pusher or pusher nut 70 A plurality of items 50 are shown loaded in the dispenser. Items 50 are annular and arranged in a stack 51 on the spine 40, resting on the pusher nut 70.

In this embodiment, spine 40 is hollow and exhibits a void 80 along its length and thereby through the main axis of dispenser 1.

In a production version of the dispenser 1, several of the above components are preferably made to have a substantially or semi-airtight (or smelltight') fit. -Tube

The tube 10 incorporates an external feature (such as a ridge or thread) enabling the user to snap' or screw the cap 20 securely into place. Alternatively, the cap may be secured by friction. Once secured, the cap 20 should form a smelltight' / substantially or semi-airtight seal.

The lower (or non-dispensing) end of the tube 10 incorporates features to secure the threaded spine 40 during assembly (e.g. a snap fit'). -Cap

Figure 4 shows the cap 20 in more detail.

The cap 20 may be designed as an item analogue', resembling the object being dispensed e.g. a Polo mint (potentially also featuring the traditional embossed lettering), and may retain the same proportions as those of an actual mint. This analogue also serves as a grip for removing the cap 20 from the tube 10.

The cap 20 uses an external snap-fit or screw-fit to fit to the tube 10.

The cap 20 incorporates a hole 25 which mates with the upper end of the threaded spine 40 to create a smelltight'/ semi-airtight seal. This hole 25 is intended to resemble the centre of the item to be dispensed, for example a mint, although its dimensions may not be directly proportional.

-Twist grip Figure 5 shows the twist grip 30 in more detail.

Twist grip 30 is located at the lower (non-dispensing) end of the tube 10 and allows the user of the dispenser ito rotate the spine 40 thereby propelling the nut 70 along the spine 40.

This grip 40 resembles one of the tube's contents (e.g. a Polo mint). This item analogue also features a fine grip around its circumference, similar to that on the cap of a plastic drinks bottle. This grip should be clearly visible to the eye because it informs' the user which end of the dispenser I to grip and rotate (because cap and grip may be similar).

Like the cap, the twist grip also features a hole, which mates with the hole at the base of the threaded spine. This hole is intended to resemble the centre of one of the items being dispensed, although its dimensions will not be directly proportional. There is no requirement for this mating to be smelltight' I airtight.

In order to reduce the number of components in the dispenser (from 5 to 4), it would be preferable for the twist grip to be incorporated within the threaded spine component.

-Threaded spine Figure 5 shows the threaded shaft or spine 40 in more detail.

The maximum diameter of the threaded spine 40 must not exceed the minimum internal diameter of the void (or hole) within the item to be dispensed.

In some embodiments, the centre of the spine 40 incorporates a parallel internal tube 60 from base to tip. This feature may pose a significant challenge for some high volume moulding machinery and is not, therefore, incorporated in all dispenser models.

The upper end of the spine 40 mates with the cap 20, providing a semi-airtight (or smelltight') fit.

The thread on the spine 40 is calibrated to dispense one item 50 per 120° (degree) rotation clockwise (i.e. one natural twist of the thumb and forefinger). If this calibration is not technically feasible, a 1800 or 240° rotation may be adopted (i.e. two twists per dispensed item). Other calibrations may also be used.

In some embodiments, each dispensing rotation of the spine 40 provides tactile feedback to the user by means of a click' (which might also be audible).

In order to mate the spine 40 with the tube 10, a feature towards the axial base of the spine 40 should snap-fit' into place. This fitting will require a semi-airtight (or smelltight') fit in production models.

The very base of the spine 40 has a feature enabling the twist grip 30 to be mated during assembly (e.g. by snapping', screwing or locking into place). The twist grip 30 is listed as a separate component, because high volume moulding restrictions may prevent the inclusion of such a feature on the threaded spine component 40.

-Pusher nut Figure 6 shows the pusher or pusher nut 70 in more detail.

The nut 70 is threaded onto the spine 40 during assembly.

The central void of the nut 70 uses the same calibration of thread as the spine 40.

The nut 70 is prevented from rotating within the tube 40 by the longitudinal rail (see Figure 8), which is integral to the tube's interior wall. A feature on the nut (such as fins 72) abuts or otherwise interacts with the rail in order to prevent rotation. A number of fins 72 are shown arranged equiangularly about the pusher axis.

Rotation of the threaded spine -according to the thread characteristics either clockwise or anticlockwise about its axis -therefore causes the nut to travel towards the dispensing end of the tube, releasing the contents of the tube in a controlled fashion.

The nut occupies valuable internal space within the tube which might otherwise be used to hold the tube contents. Therefore the design of the pusher nut should aim to minimise its longitudinal depth.

-Integral longitudinal rail' Internally, the tube walls feature an integral longitudinal rail' 100. This rail prevents rotation of the pusher nut 70 within the tube 10 by interacting with fins 72 on the pusher 70, while guiding the nut upwards' (i.e. towards the open end of the tube) during the dispensing process.

-Twist action feedback' In order to improve the sensory experience of using the dispenser, feedback is optionally provided to the user in the form of a (possibly audible) click' for each dispensing rotation (or partial rotation) of the twist grip 30.

This tactile feature may be achieved by the addition of formations such as bumps or resistance points at angular intervals corresponding to the dispensing of a single item e.g. at 1200 intervals. This may involve rigid bumps or resistance points between the tube 10 and spine 40. An alternative configuration uses tangs' integral to the tube 10 or spine 40 which audibly flick' each passing item in the stack 51 as they are dispensed.

-Resistance grips' Figure 8 shows the resistance grips 90 in more detail.

The upperldispensing end of the tube 10 also features three integral resistance grips' 90. These control the release of the tube's contents as they emerge. The length and resistance of the grips 90 is determined by their ability to grip each item 50 firmly in the dispensing position' (enabling easy removal using the thumb and forefinger, ideally without needing the operator of the dispenser to touch the item -say when offering an item to another party).

The resistance offered by the grips 90 may provide some of the feedback for the dispensing twist action, including, for example, the (possibly audible) click' feature in certain configurations.

In some embodiments the resistance grips 90 may be sufficiently resilient to support the weight of the entire stack 51 of items 50 in a fully-loaded dispenser I even when the dispenser is completely inverted.

-dimensions The dimensions of a single Polo mint are approximately as follows: Max depth (excluding embossed text) 5 mm External diameter 19 mm Internal hole' diameter 7 mm The designs of both the cap 20 and twist grip 30 incorporate mint analogues'.

The size of these analogues should be directly proportional to the mints dispensed from the tube. Therefore, the ratios to be used in creating the analogues are as follows: Max depth (excluding embossed text) 1 External diameter 3.8 Internal hole' diameter 1.4 Typically, a production dispenser I will be the same length as a standard 23-mint retail pack of Polos, i.e. 117 mm, but wider than a standard retail pack (by approximately 4 mm) due to the thickness of the tube 10 walls and the inclusion of internai guide rails 100.

More precise dimensions and tolerances would be used for the exacting design and assembly standards associated with modern high volume manufacturing.

Variations & modifications In alternative embodiments, threaded shaft or spine 40 is solid.

Alternatively, the threaded shaft or spine 40 is closed at one or both end ends -or at one or points in between -thereby providing a material saving without necessarily creating a central void 80 extending along the length of the main or longitudinal axis of the tube 10.

In some embodiments, the cap 20 may feature a (preferably axial) chuck key'.

This could be used in addition to or to entirely eliminate the need for a twist grip at the lower end of the tube 10. Upon removing the cap 20, the user would insert the chuck key of the cap 20 into the hole at the underside of the tube 10, engaging with the shaft 40, and thereby enabling the shaft 40 to be rotated by means of rotating the cap I chuck key -and also providing a housing for the otherwise loose cap 20.

In alternative embodiments, the shaft or spine 40 is not necessarily co-axial with the tube 10, or in some embodiments is adjacent to or forms part of the tube wall.

In some embodiments, the dispenser comprises a pusher threadably engaged with a threaded shaft. The dispenser may effectively be tubeless'.

Alternatively, the tube may act as the shaft, for example, the thread being along the inner wall of the tube, optionally with rails housed on the spine.

In other variants, the threaded shaft may be hollow and act as the tube.

The tube may be made of biodegradable' material. One or more of the components may be edible.

In some embodiments, the tube (or some other part of the dispenser) is made -at least in part -of translucent or transparent material to allow the fill level of the tube to be determined. For example, the tube wall may comprise a window to allow viewing of the items contained therein.

The items 50 to be dispensed may have one or more of the following characteristics: * items may be of non-circular or irregular shape eg. triangular, hexagonal, irregular polygon * items may be of different shapes * items may be annular or generally have a aperture through which they may be loaded onto the threaded spine * items may have aperture which is non-central or non-axial * items may have an internal thread Where the items 50 have an internal thread, this may eliminate the need for a pusher nut. The products would travel along the tube when the shaft is rotated (providing some form or rotational restraint is incorporated in their shape/design, e.g. triangular confections in a triangular tube could not rotate and would therefore travel towards the dispensing end of the tube when the shaft is rotated.

The tube 10 is shown as having a circular cross-section in the above examples; tubes with a non-circular cross-section may also be used. The pusher nut 70 may in such alternative embodiments also be non-circular and consequently may be prevented from rotating in the tube when the shaft or spine 40 is rotated by means of the twist grip 30 due to direct interaction of the pusher nut with the side walls of the tube, rather than, say, by the interaction of fins located on the pusher nut with a longitudinal rail' integral to and located on the inner wall of the tube.

In many of the described embodiments the main purpose of the pusher 70 is to advance a series of independent solid or rigid items 50 along the dispensing tube 10. This allows for a wide variety of alternative pusher forms and pusher/thread arrangements compared to those embodiments for the dispensing of non-rigid and/or continuous product which may require the pusher to also have the characteristics of a container or receptacle to contain or support the product being dispensed.

Alternative embodiments have resistance grips 90 which are wider and/or thicker than those shown in the accompanying figures; the number of resistance grips 90 may differ and/or they may be differently distributed about the axis of tube 10.

The tube-based resistance grips 90 described previously grip the item 50 by its outer features about its (outer) circumference. In some alternative embodiments, the resistance grips 90 may (subject to moulding technology capabilities) be located protruding from the end of the rotatable shaft 40. These alternative shaft-based grips would resist or grab the item 50 around the circumference of its internal void.

Early prototype designs have been influenced by concerns about the practicalities of loading the dispenser with its contents. The existence of the resistance grips at the open end of the tube may hinder the insertion of solid contents from that direction. Consequently, the assembly and loading of early prototypes have involved first stacking the contents onto the threaded spine. The spine is then inserted within the tube from below (i.e. the non-dispensing end) and clicked into place.

It is currently assumed that the dispenser will be disposed of after the consumption or distribution of its contents. For this reason, recycling and sustainability characteristics (e.g. single material, low mass) have informed the design. However, a re-usable I refillable version of the dispenser is feasible.

This would need to be marketed in conjunction with bespoke devices capable of dispensing the products directly into an empty tube (while simultaneously returning the pusher nut to its starting position).

In an automated manufacturing environment, it may be assumed that bespoke machinery will be designed to facilitate top loading' of the tube, using some method to by-pass the resistance grips. It is therefore assumed that such machinery will eliminate the need for a separate twist grip component due to reconfiguration of the non-dispensing end of the tube and the method of fitting the spine to the tube.

Alternative embodiments may be adapted for dispensing other types of item, such as nuts and washers and other construction materials. Variations may also be adapted for dispensing liquids or powders.

In summary, an aspect of the invention comprises providing a dispenser with resistance grips which provide sensory feedback and grab each dispensed item for presentation to the user.

It will be understood that the present invention has been described above purely by way of example, and modifications of detail can be made within the scope of the invention.

Each feature disclosed in the description, and (where appropriate) the claims and drawings may be provided independently or in any appropriate combination.

Reference numerals appearing in the claims are by way of illustration only and shall have no limiting effect on the scope of the claims.
