DETAILED DESCRIPTION OF EMBODIMENT(S)
(22) Referring firstly to
(23) The dispenser 10 is of the kind described in WO2011/036477, although other forms of suitable dispenser are known in the art, e.g. as marketed under the trade mark ONE SHOT.
(24) An example of a container suitable for use in the dispenser 10 is indicated generally at 20 in
(25) Typically, in use, a plunger within the dispenser is used to push against the upper surface 26 of the deformable section 24, causing it to move inwardly, thereby reducing the internal volume of the container 20. This action causes product to be extruded through the outlet 40.
(26)
(27) Accordingly, the outlet 40 has an open and a closed condition, for dispensing and storing ice cream respectively. In
(28) The movable parts 42 are hinged such that they can be displaced outwardly from the lower container part 30 to an open position, e.g. as illustrated in
(29) As will be described in more detail below, each movable part 42 has a complex shape, with multiple advantages.
(30) In the open condition, product is shaped as it is dispensed through the outlet 40. In particular, the movable and fixed parts 42, 44 cooperate to shape product as it is dispensed through the outlet 40.
(31) In the closed condition, each fixed part 44 partially overlaps its adjacent movable parts 42, to provide a retaining force against movement of the movable parts from their closed position, e.g. as shown in
(32) A continuous wall 46 projects from the underside of the container 10. The wall 46 defines a ring around the outlet 40, co-axial with the outlet 40. It projects in a perpendicular direction to the flat base 32 of the lower container part 30, i.e. with an inner surface of the wall extending parallel to the central axis of the outlet 40. The wall 46 prevents the movable parts 42 from overextending, reducing the risk of the movable parts 42 breaking off during a dispensing operation. The wall 46 may cooperate with the movable parts 42 helping them to form a desired shape of the outlet 40 in an open condition.
(33)
(34) The fixed parts 44 of the outlet 40 are generally triangular having two free sides when the outlet is in an open configuration. In the embodiment of
(35) Each movable part 42 is moulded with a recess in its outer surface, such that a projection 48 is created on an inner surface of each movable part. When the movable parts 42 are located in the open position, the projections 48 extend into the outlet 40, and—in combination with the triangular shape of the fixed parts 44 (extending in a direction parallel and coincident with the flat base 32)—serve to create the star-shaped opening 50, as can be see clearly from
(36)
(37)
(38) Each movable part 42 has a free end 54, distal the hinge 52. The free end 54 has a planar end surface 56 (shown more clearly in
(39) Each movable part 42 has two free sides 58, 59 extending from the free end 54 to the hinge 52. The two free sides 58, 59 are of unequal length, defining one long free side 58 and one short free side 59. The two free sides 58, 59 of the movable parts 42 define a planar surface having a wedge-shaped profile, as can be seen most clearly from
(40) The long free side 58 of each movable part 42 extends at an acute angle between the hinge 52 and the end surface 56, and extends radially with respect to a central axis of the outlet 40. The end surface 56 is shorter in length than the long side 58. The short free side 59 of each movable part 42 extends between the hinge 52 and the end surface 56 in a direction perpendicular to the hinge 52. The short free side 59 is longer than the end surface 56.
(41) It can be seen from the plan view of
(42) Advantageously, the combination of long and short sides of the movable and fixed parts has been found to provide an improved seal within the container 10 when the outlet 40 is in the closed condition, and also assists in a desirable shape-forming configuration, for the ice cream being dispensed through the outlet 40.
(43)
(44)
(45)
(46)
(47) Although not shown in the figures, to further discourage splitting, the thickness of the hinge 52 may also vary along its length. For example at either end, adjacent the fixed parts 44, it may have an increased thickness e.g. the joint 66 may have an increased depth at either end of the hinge. This would advantageously increase the strength of the hinge at its end regions and minimise the risk of tearing along the hinge 52.
(48) The container 20 is manufactured by injection moulding. It is moulded with the outlet 40 in a partially open condition as illustrated in
(49) In use, the container 20 is placed in the seating 12 of an appropriate dispenser such as the one illustrated in
(50) During the operation, the wall 46 prevents the movable parts 42 from overextending, keeping the star-shape as desired and reducing the risk of the movable parts 42 breaking off during the operation. At the end of the operation, the natural bias of the movable parts 42 towards the closed position helps to cut off the stream and ‘crimp’ the product.
(51) The diameter of the wall 46 is lower than the diameter of a recess (not shown) in the seating 12 of the dispensing machine 10. The wall 46 advantageously provides a barrier between the outlet 40 and the seating 12, preventing product from transferring to the seating 12 during dispensing, making the machine more hygienic and reducing the need for a user to clean the dispenser after each operation.
(52) The container 20 is nestable with other containers of the same dimensions and the same type so that they can be filled with product on high-speed filling machines. A base support may be required to apply pressure against the assembled sections whilst the product is being filled and the lid is applied and closed.
(53) It will be appreciated that further variations can be made without departing from the scope of the invention. For example, the tabs 60 could be in a different location such as attached to the wall 46 or the movable parts 42.
(54)
(55)
(56) A land 106 is formed between the movable parts 102. The land 106 is a membrane between the movable and fixed parts 102, 104 of a reduced material thickness, suitable to form a line of weakness capable of breaking if a sufficient force is applied to the outlet 100. Each land 106 is a continuation of a line of weakness (formed by a region of reduced material thickness) extending between the movable and fixed parts 102, 104.
(57) To strengthen the fixed parts 104, each fixed part 104 includes a strengthening rib 108 on an underside thereof. The rib 108 extends substantially along the length of the fixed part, from an annular wall 110 (surrounding the outlet and projecting outwardly from the bottom surface of the container 90) to a location proximal (but spaced from) a free end of the fixed part. As can be seen from
(58)
(59) Each movable part 102 is substantially the same as the movable parts 42 of the container of
(60) The outlet 100 is moulded in a closed condition and the land 106 is capable of being broken open prior to a dispensing operation (described in more detail below), in order to free the movable parts 102 to move outwardly from the container 90 under pressure from the extrusion of product, to adopt an open configuration as shown in
(61) Although particularly suited for a frozen confection, e.g. ice cream, sorbet, frozen yoghurt, the outlet configuration of a plurality of movable and fixed parts shown and described herein could be used with a range of different types of container, provided that the container is of a kind intended for use with a force applied to the container in order to extrude product through the outlet.
(62)
(63) Looking at
(64) Alternatively, although not shown in the Figures, the land 106 of the container 90 could be broken in a different way. For example, the container 90 could be simply secured in a ring-type seating before a surface of an actuating member is made to engage the outlet 100, applying a force to break the land 106. The outlet of the container could also be pushed into engagement with some other form of projection dimensioned to allow the movable parts to flex inwardly and cause fracture of the land 106.
(65)
(66)
(67)
(68)
(69)
(70)
(71) The drum 166 is then rotated by 90 degrees in order to move the container 90 from the first location 170 to a second location 172, where a dispensing head 150 applies a force to the container 90, dispensing product as described in more detail above.
(72) The drum is then rotated by another 90 degrees in order to move the container 90 from the second location 172 to a third location 174, before the drum is rotated another 90 degrees in order to move the container 90 from the third location 174 to a fourth location 176. At the fourth location 176, the depleted container 90 is disposed of.
(73) The storage area 164 includes a magazine 180 of containers 90 containing product, to be used to refill the aperture 168 at the first location 170 after every time the drum 166 rotates. The magazine 180 is a rotatable carousel and includes six stacks 182 of containers 90. Each stack is arranged vertically and includes multiple containers 90. When a container 90 is removed from a stack 182, the remaining containers 90 fall downwardly under gravity to take the place of the removed container 90. The magazine 180 is arranged such that the bottommost container 90 of one stack 182 is located adjacent the first location 170. Therefore, in use, a container 90 can be transferred from the magazine 180 to the drum 166. This can be achieved with a suction mechanism or other mechanical release (not shown). When a stack 182 is depleted, the magazine 180 can rotate to present another stack. Therefore, at least one stack is always coaxial with the aperture 168 at the first location 170.
(74) In exemplary embodiments, the vending machine 160 includes a user interface (e.g. of the kind indicated generally at 200 in
(75) Alternatively, one or more of the mechanisms described herein may be incorporated into a dispensing apparatus (as opposed to a vending machine) configured for manual operation rather than a wholly automated process based on a user selection and or user payment to the machine. For example, the dispensing apparatus may include a seating for receiving a container of the kind described herein and having a land 106 between fixed and movable parts of the outlet 100 (i.e. intended to be broken prior to a dispensing operation), wherein the apparatus includes a breaker mechanism 148 and a dispensing head 150, such that a container as set forth can be placed in the seating, and wherein, in response to a human operator command (e.g. made via a button or other suitable user interface on the apparatus), the breaker mechanism 148 will act to break the land 106, before the dispensing head 150 acts on the container to express product through the outlet. The apparatus may be of a kind where the container needs to be placed in the seating by a human operator, or may be of a kind including a storage area provided with a stock of sealed containers of the kind set forth, which can be automatically delivered to or stored in an appropriate seating forming part of the apparatus, for use in a dispensing operation in response to a human operator command.
