Referring now to
The dispenser 100 includes a chassis 120 (see
The chassis 120 includes two side walls 124, and a top wall 126, a bottom wall 128 and an end wall 130 which together define the chamber. The chamber is open at one end 132 opposite the end wall 130 for the insertion of the cartridge 150 into the chamber. The top wall 126 includes a dispensing aperture 126a (see
The chassis 120 is retained within the outer casing 110 by means of a locking key 114 which extends from the outside of the outer casing 110, though an end wall thereof, and engages with a corresponding cooperating means 120a formed on the end wall 130 of the chassis 120. Such engagement may comprise a press-fit, snap-fit or any other suitable engagement means or element within the scope of the invention.
The inside face of each chassis side wall 124 includes a plurality of vertical ribs 134 (see
An implementation of a cartridge 150 of the invention, for use with the dispenser 100, is shown in
A piston 170 (see, for example,
The piston 170 is received within the cartridge 150 with the front face 172a nearest the chassis open end 132 and the side wings angled away from the chassis open end 132. The piston 170 is configured such that when it is received within the cartridge 150, the side wings 174a of panel element 174 extend though the apertures 154a in the side walls 154.
The chassis 120 further comprises a leaf spring 136 and a receiver 138 (see, for example,
As illustrated in
The chassis side wall 124 on which the lifting arm 180 is mounted also includes a pair of bosses 188 situated laterally (see, for example,
The same side wall 124 of the chassis 120 which supports the lifting arm 180 also includes a guide track 190 formed thereon defined by a curved protruding wall element upstanding from the face of the side wall 124. The guide track 190 is positioned above the support lug 186 and comprises an elongate teardrop loop defined around an island element 190a (see
As illustrated in
Operation of the cigarette dispenser 100 of the invention, in combination with a cartridge 150 of the invention, will now be described, with particular reference to
To dispense a cigarette S from the dispenser 100, a user pushes the end door 112 as an operating button inwards towards and into the outer casing 110. The end door 112 engages and actuates the end wall 160 of the cartridge 150 to cause the cartridge 150 to slide forwards further into the chamber 122 of chassis 120. This is shown in the movement from
As the user releases the end door 112, the biasing force exerted by the compressed leaf spring 136 pushes the receiver 138 and abutting cartridge 150 backwards in the opposite direction to return to the start position. However, the side wings 174a of the piston 170 now act as pawls and bind against the vertical ribs 134 on the inside of the side wall 124 of the chassis 120 which they previously rode over on the forward movement and thereby prevent the piston 170 from moving backwards and returning with the cartridge 150. This causes the cartridge 150 to move backwards under the force of the leaf spring 136 but the piston 170 and row of cigarettes S ahead of the piston 170 remain stationary in the advanced position relative to the chassis 120. This causes the lead cigarette S within the cartridge 150 to be pushed out of the cartridge open end 162. As the cartridge 150 moves backwards relative to the chassis 120 and to the piston 170, the uppermost and lowermost corners of the elongate element 172 of the piston 170 ride over the adjacent ratchet teeth 156a, 158a of the cartridge 150 and locate against the flat vertical face 159 (see
As the receiver 138 moves backwards under the force of the leaf spring 136, it moves towards the stationary row of cigarettes S and engages the lead cigarette S just ejected from the cartridge 150, into the channel 138a. The lifting foot 140, at this time, also moves backwards with the receiver 138 so that the lead cigarette S becomes located on top of the platform 140a and, simultaneously, the second coupling pin 192b begins to travel along the lower return path in the guide track 190 below the island element 190a. The channel 138a in the receiver moves into alignment with the dispensing apertures 126a, 110c in the chassis 120 and outer casing 110, respectively. This part of the dispensing operation is shown in the movement from
Finally, as the end door 112 and cartridge 150 reach the end of the backward movement and return to the starting position again, the second coupling pin 192b moves backwards in the lower part of the guide track 190 until it reaches and pushes against the contact end 182a of the lifting arm 180, thereby rotating the lifting arm 180 upwards about the support lug 186 to its uppermost position with the support arm 184 abutting against the upper boss 188. This causes the distal end of the inner arm 182 located between the guide pins 140c of the lifting foot 140 to lift the lifting foot 140 upwards to its raised position, as the guide pins 140c travel upwards within the guide slots 138b, 124a of the receiver 138 and the side walls 124 of the chassis 120. This causes the lead cigarette to be lifted upwards on the platform 140a and out of the dispensing apertures 126a, 110a in the chassis 120 and outer casing 110 respectively. This part of the dispensing operation is shown in the movement from
At the very end of its movement, the second coupling pin 192b passes over the contact end 182a of the lifting arm 180, and is therefore ready to repeat the above-described process by pushing and rotating the lifting arm 180 downwards again on the next dispensing operation. However, after the second coupling pin 192b passes over the contact end 182a of the lifting arm 180, the lifting foot 140 and lifting arm 180 may naturally fully or partially drop under their own weight, although this does not affect subsequent dispensing operations.
The above-described dispensing process is repeated for each cigarette S to be dispensed from the cartridge 150 out of the dispenser 100, and each time, the piston 170 indexes forwards relative to the cartridge 150 and chassis 120 by the ratchet mechanism comprising the side wings 174a on the vertical ribs 134 and elongate member 172 ends on the ratchet teeth 156a, 158a. When the cartridge 150 is empty, the forwards movement of the cartridge 150 pushes the piston 170 forwards right to the open end 162 of the cartridge 150 such that the side wings 174a engage with the edges of the apertures 154a and are deflected inwards as the piston 170 is further advanced so that they lie flat against the side walls 154 of the cartridge. In this position, they are out of snagging engagement with the vertical ribs 134 on the inside walls 124 of the chassis 120. A user may then open the end door 112 and easily remove the spent cartridge 150 and replace it with a fresh full cartridge 150. The dispenser 100 is then reloaded and ready for use as described above.
The invention described above includes a dispenser 100, a cartridge 150 for use with the dispenser 100 and a dispenser 100 in combination with the cartridge 150. An alternative embodiment of a cartridge 250 of the invention will now be described which is also suitable for use with the same dispenser 100 as already described, and so detailed description of the dispenser 100 will not be repeated.
The alternative embodiment of a cartridge 250 of the invention is shown in
A piston 270 (see
The piston 270 is received within the cartridge 250 orientated such that the side wings 274 and end tabs 276 angled away from the open end 262 with the end tabs 276 resting against the top and bottom walls 256, 258 of the cartridge 250 between the ribs 256a, 258a. The piston 270 is configured such that when it is received within the cartridge 250, the side wings 274 extend though the apertures 254a in the side walls 254. Furthermore, both the side wings 274 and the end tabs 276 are elastically resilient and so when caused to be deflected inwards, exert a return biasing force in an outward direction.
The operation of the dispenser 100 in use with the alternative cartridge 250 of the invention is very similar to that described above with the first-described cartridge 150, and so will not be repeated here in its entirety. Only the function of the differing features will be described.
To dispense a cigarette S from the dispenser 100, end door 112 is pushed inwards towards and into the outer casing 110. The end door 112 pushes the end wall 260 of the cartridge 250 to cause the cartridge 250 to slide forwards further into the chamber of chassis 120. This is shown schematically in the movement from FIG. 28A1 to 28C1 and 28A2 to 28C2. As this happens, the end tabs 276 of the piston 270 act as pawls and bind against the horizontal ribs 256a, 258a. Thereby, the piston 270, together with the smoking articles ahead of the piston 270, is forced to move forwards with the cartridge 250 relative to the chassis 120. As the piston 270 moves forwards within the chassis 120, the side wings 274 of the piston 270 are deflected inwards (see arrows P1 in FIG. 28B2 and
As the user releases the end door 112, the biasing force exerted by the compressed leaf spring 136 pushes the receiver 138 and abutting cartridge 250 backwards to return to the start position. However, the side wings 274 of the piston 270 now act as pawls and bind against the vertical ribs 134 on the inside of each side wall 124 of the chassis 120 which they previously rode over on the forward movement and thereby prevent the piston 270 from returning with the cartridge 250. This causes the cartridge 250 to move backwards under the force of the leaf spring 136 but the piston 270 and row of cigarettes S ahead of the piston 270 remain stationary in the advanced position relative to the chassis 120. A lead cigarette S in the cartridge 250 is pushed out of the cartridge open end 262. As the cartridge 250 moves backwards relative to the chassis 120 and to the piston 270, the end tabs 276 of the piston 270 ride over the next adjacent horizontal rib 256a, 258a and locate thereagainst. This position is shown in
Although an exemplary embodiment of the dispenser of the invention and two exemplary embodiments of the cartridge of the invention for use in such a dispenser have been described above, it will be appreciated that various modifications may be made to these embodiments within the scope of the invention which is defined by the claims hereafter, the invention also including a dispenser in combination with a cartridge. Any combinations of non-mutually exclusive features described above are intended to fall within the scope of the invention.
The first-described cartridge 150 is intended to be made from card, although may be made from other suitable materials such as plastic, or a combination of materials (for example, the piston 170 may be made from plastic and the blank 172 of the cartridge 150 made from card, or vice versa). Also, although the piston 170 of the first cartridge 150 is described as being made from two separate components, it may equally be made integrally as single body.
Similarly, the alternative cartridge embodiment 250 may be made from any suitable material such as plastic or card, or a combination of materials. Also, although the piston 270 of the second cartridge 250 is described as being made as single integral body, it may equally be made from two or more separate components joined together.
The cartridge 150/250 is intended to be a replaceable and disposable component with which the dispenser 100 can be reloaded with a new full cartridge 150/250 once all of the cigarettes in the previous cartridge 150/250 have been dispensed and said previous cartridge 150/250 removed from the chassis 120 and discarded.
The first-described cartridge 150 is shown as including a side tab 164 which extends across the open end 162 of the cartridge 150. This is intended to retain the cigarettes within the cartridge 150 during manufacture, packing and distribution, until the end user is ready to load the cartridge 150 into the dispenser 100. At this point, the user breaks the tab 164 manually by tearing or otherwise, prior to insertion of the cartridge 150 into the dispenser 100. However, the tab may be breakable upon first dispensing operation, for example, if a line of weakness is provided in the tab 164 such that when the piston 170 is first indexed forwards relative to the cartridge 150, the lead cigarette S breaks the tab 164 to allow it to be dispensed. The second described cartridge 250 may include such a retaining and/or breakable tab within the scope of the invention.
In both the first-described cartridge 150 and the alternative cartridge 250, the cartridge 150/250 may be initially supplied with the piston 170/270 positioned back within the cartridge 150/250 proximate the rear wall 160/260 thereof such that the side wings 174a/274 of the piston 170/270 are restrained within the cartridge 150/250 between the side walls 154/254, and not extending through the large apertures 154a/254a in the side walls 154/254. Then, upon an initial dispensing operation of the dispenser 100 as described above, the piston 170/270 is moved towards the open end 162/262 of the cartridge 150/250 until the side wings 174a/274 of the piston 170/270 reach the large apertures 154a/254a in the side walls 154/254 and spring outwardly to extend therethrough. Alternatively, however, the cartridge 150/250 may be initially supplied with the side wings 174a/274 of the piston 170/270 already protruding through the large apertures 154a/254a in the side walls 154/254.
The locking key 114 which secures the chassis 120 within the outer casing 110 can be detachable from the cooperating means on the end wall 130 of the chassis 120 to enable the chassis 120 to be removed from the outer casing 110. This facility may enable a user to interchange different styles or designs of outer casing for the dispenser 100, while retaining the same internal components of the chassis 120.
The end door 112 is described as being slidable within the outer casing 110 and pivotable relative thereto to enable reloading of the chassis 120 with a new cartridge 150/250. However, the end door 112 may equally be removable from the outer casing 110 within the scope of the invention. It will also be appreciated that the end door could be provided as a replaceable component attached to the cartridge 150/250 and engageable with the lifting arm mechanism upon replacement of the cartridge 150/250. Furthermore, although the above embodiments describe the dispenser 100 including a mechanism to lift the cigarettes S as well as sequentially index them out of the cartridge 150/250 to be dispensed, the invention is not intended to be limited to a dispenser having the above-described lifting mechanism, nor one having a lifting mechanism at all, and may simply index and dispense cigarettes from the cartridge 150/250 without also lifting them from the dispenser 100 in a combined movement.
In addition to the above description and listed Figures, two sets of sequential drawings of the stages of operation of the dispenser 100 in use with each of the two embodiments of the cartridge 150/250 are included as Annex 1 and Annex 2 respectively. The drawings of these annexes are side and plan views and show the internal features of the dispenser 100 and cartridge 150/250, with one side view sequence in each Annex also showing the cigarettes within the cartridge 150/250. The reference numerals are omitted from the drawings of these annexes for clarity but correspond to all of the numbered features shown in
