Embodiments of the present invention relate to a container, dispensing device, and method of dispensing goods.
Containers are often used to deliver goods to a destination. For example, in the soft drinks industry, a reusable container containing plastic preforms is used to deliver the preforms to a soft drinks manufacturer. The preforms are blown out to form bottles, washed and filled with a soft drink. A cap is screwed onto the bottle to seal the bottle.
To dispense the preforms, the container is loaded onto a dispensing device by a forklift truck. The forks of the forklift truck may strike the support feet 106 and cause them to be damaged. This then requires replacement of the trapdoors 102 or the whole container 100.
Once the container 100 has been loaded onto the dispensing device, the two trapdoors 102 in the base of the container are opened, and the preforms fall out of the container into a hopper underneath the container. An uncontrolled quantity of the preforms falls into the hopper, as all of the preforms in the container fall into the hopper.
During transportation and storage, the base of the container 100, including the support feet 106, may collect debris. This debris may fall into the hopper 200 along with the contents of the container, which causes hygiene problems. Also, the reusable container 100 must be returned for refilling. The containers must, therefore, be stored and transported, which has associated costs.
The container 100 typically holds up to around 7000 preforms. The bottles formed from the preforms can hold various products. Different products are typically associated with different caps. Caps are not washed by the manufacturer, for example the soft drinks manufacturer, and are therefore sealed in plastic bags and transported in cardboard boxes before being transported to the manufacturer. The boxes and bags are manually opened by the manufacturer using knives, and the caps are manually poured into a hopper. As the caps are only for a single product, only a certain number of caps may be required. Therefore, to avoid handling or waste of caps at the end of a manufacturing run for a product, only a certain number of caps is poured into the hopper. The approximate number of caps poured into the hopper is judged visually by the person handling the caps. Once the approximate required amount has been poured into the hopper, the bag inside the box must be resealed. This is typically done using sticky tape, which can be messy, and may require cutting with a knife when more of the caps are required.
The use of knives has associated health and safety concerns. Also, when a box is empty, the box and the bag contained inside the box must be discarded, which has associated costs and environmental impact. Each box contains around 15,000 caps, which equates to around 20 minutes of product manufacturing time. Therefore, a large number of empty boxes and bags must be discarded. The caps are not transported in the containers 100, as when the trapdoors 102 are opened, the bag itself may fall into the hopper, and if the bag was secured inside the container 100, a person would have to cut the bag using a knife when positioned underneath the container 100, which has unacceptable health and safety concerns.
It is an object of embodiments of the invention to at least mitigate one or more of the problems of the prior art.
According to a first aspect of embodiments of the invention, there is provided a container having openings on an inside surface, wherein the openings are for use with vacuum means for retaining a liner within the container whilst contents of the liner are being dispensed.
Thus, a container can be used to store, for example, caps which are stored within a liner, for example a plastic bag. The liner is retained within the container by using vacuum means such as, for example, a vacuum pump, and the liner can be easily removed when required, for example by disconnecting the vacuum pump.
In certain embodiments, the container comprises a base, wherein the base includes a first openable closure, and wherein the first closure is arranged when opened to direct contents being dispensed from the container. Therefore, the contents can be directed, for example, away from the underneath of the container, and debris on the underside of the container (for example, on the base or on the first closure) does not become mixed with the dispensed contents of the container. For example, the container may have a footprint whilst resting on the ground, where the footprint comprises the parts that touch the ground and the area between those parts.
According to a second aspect of embodiments of the invention, there is provided a container including a base, wherein the base includes a first openable closure, and wherein the first closure is arranged when opened to direct contents to be dispensed from the container. Therefore, the contents can be directed, for example, away from underneath the container, and debris on the underside of the container (for example, on the base or on the first closure) does not become mixed with the dispensed contents of the container.
In certain embodiment, the container comprises openings on an inside surface of the container, wherein the openings are for use with a vacuum pump for retaining a liner within the container whilst contents of the liner are being dispensed. Therefore, the liner is not dispensed along with the contents.
In certain embodiments, the first closure comprises a trapdoor. A trapdoor is of simple construction. As the first closure comprises only one trapdoor, support feet are not required in a position where they may be struck, for example, by the forks of a forklift truck. Preferably, the first closure includes flaps, and the first closure and the flaps form a spout for directing the contents when the first closure is opened. The direction in which the contents are directed can, therefore, be well defined.
Preferably, the trapdoor is openable such that an edge of the trapdoor is positioned close enough to or beyond an edge of a footprint of the container so as to direct contents outside the footprint. The contents are therefore not mixed with any debris on the underside of the container that falls into the area of the footprint.
In certain embodiments, the container comprises a lid having a second openable closure. The container can therefore be used for fast, easy dispensing of an uncontrolled quantity of the contents, and also for dispensing of a controlled quantity.
In certain embodiments, the container includes a liner, and the lid includes means for sealing the liner. This avoids the need to use sticky tape to seal the liner.
Preferably, the means for sealing the liner comprises a cylinder having a groove or through hole for receiving open ends of the liner. The means for sealing the liner is, therefore, of cheap and/or simple construction. Preferably, the cylinder is rotatable, so that the liner can be wrapped around the cylinder to seal the liner. Preferably, the means for sealing the liner comprises locking means for locking rotation of the cylinder. Therefore, unwanted rotation of the cylinder to unseal the liner can be avoided.
In certain embodiments, the container comprises first and second pivotable walls which may be pivoted so as to lie flat against the base, and third and fourth foldable walls which may be folded so as to lie flat against the base, such that the container may be reduced to a reduced size, collapsed state and returned to an upright state. The container, when empty, can therefore be stored and/or transported more efficiently when in the collapsed state.
According to a third aspect of embodiments of the invention, there is provided a container having a first openable closure for dispensing of an uncontrolled quantity of contents, and a second openable closure for dispensing of a controlled quantity of the contents.
According to a fourth aspect of embodiments of the invention, there is provided a method of dispensing goods from a container, comprising opening a closure in a base of the container to dispense an uncontrolled amount of contents and to direct the dispensed contents.
According to a fifth aspect of embodiments of the invention, there is provided a method of dispensing goods, comprising: applying a vacuum pump to a container to retain a liner inside the container; and dispensing contents from the liner.
According to a sixth aspect of embodiments of the invention, there is provided a dispensing device for dispensing goods from a container, the dispensing device comprising means for rotating the container to dispense the goods from an opening in a lid of the container. The dispensing device can, therefore, dispense a controlled amount of the goods, without the need for a person to manipulate the container to dispense the goods.
In certain embodiments, the dispensing device comprises a vacuum pump for retaining a liner within the container via openings in an inner surface of the container. The container may therefore contain a liner such as a bag, and the bag can be prevented from being dispensed with the goods.
In certain embodiments, the dispensing device comprises a dispensing chute for directing goods being dispensed from the container. The goods being dispensed can therefore be directed as they are being dispensed.
In certain embodiments, the goods are dispensed into a hopper, and the dispensing device comprises a level detector for detecting whether the goods being dispensed have reached a level in the hopper, and also comprises means for stopping or reversing rotation of the container when the goods have reached the level in the hopper. The amount of goods therefore does not have to be visually inspected to determine whether or not the goods have reached the desired level. The level may be more accurately determined by the dispensing device.
Embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
The container 300 shown in
A third side wall 310 comprises two panels 312 and 314, joined together by a hinge 316. The upper panel 312 is attached to the lid 304 by a hinge 318, and the lower panel 314 is attached to the base 300 by a hinge 320. A fourth side wall 322, opposite the third side wall 310, is generally identical to the third side wall 310.
The lid 304 includes an openable closure 324 which covers an opening (not shown) in the lid 304. The closure 324 is attached to the lid 304 by tamper evident security tags 326 that must be broken in order to remove the closure 324 and access the opening.
The container 300 is collapsible, in that it can be collapsed into a collapsed state, and easily reassembled into an upright state. In the collapsed state, the container 300 fills a volume of around 30-50% of the volume it fills in the upright state. Therefore, when empty, the container 300 can be stored and transported more efficiently.
A method of reassembling the container 300 into the upright state will now be described with reference to

The side walls lock into their upright positions using spring-operated, latch mechanisms. For example, as shown in
The base 302 of the container 300 includes a trapdoor 1200 as shown in
The trapdoor includes edge support feet 1204, also shown in
The base 302 also includes substantially triangular flaps 1208 that are also shown in
When the trapdoor 1200 is closed, the contents of the container 300 (such as, for example, preforms or caps) are prevented from leaving the container through the base 302. When the trapdoor is opened, the trapdoor pivots about the hinge 1202 as shown in
The contents of the container 300 are directed in a direction 1404 that is generally away from the footprint of the container 300. That is, the container 300 has a footprint, which comprises the parts of the container that contact the ground when the container is on the ground, and also any area below the container between those parts. The edge of the trapdoor 1200 opposite the hinge 1202 is located close enough to the edge of the footprint, or beyond the footprint, such that the contents that flow out of the base 302 due to gravity do not land within the footprint of the container 300. Therefore, any debris on the underside of the container 300 (such as, for example, on the underside of the base 302 or the trapdoor 1200) that falls off whilst the contents are being dispensed does not become mixed with the contents. Substantially the entire contents of the container 300 are dispensed through the base 302 in this way, i.e. an uncontrolled quantity of the contents is quickly dispensed.
Once the contents have been dispensed, the trapdoor 1200 is pushed back into the position shown in
The lid 304 also includes means 1904 for sealing the liner inside the container 302.
A method of sealing the liner within the container 300 using the sealing means 1904 will now be described, with reference to
The outer frame 2402 includes a pair of abutments 2410 which abut against the container 300 adjacent to one side wall of the container 300 when the container is mounted on the dispensing device 2400. A pair of foot guides 2412 are located on the outer frame 2402, adjacent a side wall of the container 300 substantially opposite the side wall adjacent to the abutments 2410 when the container is mounted on the dispensing device 2400. The foot guides 2412 are located such that when the container 300 is mounted on the dispensing device 2400, support feet 1604 of the container rest on a base 2414 of the foot guides 2412. Each foot guide 2412 includes sloping side walls 2416 and 2418 that may guide the support feet 1604 as the container is being lowered onto the dispensing device 2400, and may help to correctly locate the container on the support device 2400.
The contents are dispensed in an uncontrolled manner, i.e. all of the contents are dispensed. Once the container 300 is empty, the trapdoor 1200 may be closed by operating the pistons 2408 to raise the inner frame 2404 to the position shown in
An electric motor 2814 is mounted on the fixed frame 2800 and may rotate the pulley 2804 in either direction via a band or chain 2816.
A locking arm 2820 is rotatably mounted on a pivot 2822 on the clamp cam 2806. In the position shown in
An upper clamp portion 2830 is rotatably mounted on an axle 2832 on the rotatable frame 2802. A linking arm 2834 is rotatably attached at each end to the upper clamp portion 2830 and the clamp cam 2806 respectively, such that when the clamp cam rotates in a clockwise direction relative to the rotatable frame 2802, the upper clamp portion 2830 pivots in an anticlockwise direction about the axle 2832 relative to the rotatable frame 2802. The upper clamp portion 2830 includes a chute 2836 to direct the contents of the container 300 being dispensed through the lid 304.
A vacuum pump 2840 is mounted on a pivotable arm 2842 that is attached to a pivot point 2844 on the rotatable frame 2802. A linking arm 2846 is rotatably attached at each end to the clamp cam 2806 and an end of the pivotable arm 2842 opposite the vacuum pump 2840 respectively, such that when the clamp cam rotates in a clockwise direction relative to the rotatable frame 2802, the pivotable arm 2842 pivots in a clockwise direction about the pivot point 2844 relative to the rotatable frame 2802.
To insert a container 300 into the dispensing device 2700, the motor 2814 is operated such that the pulley 2808 and clamp cam 2806 rotate in a clockwise direction about the axle 2804, relative to the fixed frame 2800 and the rotatable frame 2802. The pin 2810 on the rotatable frame 2802 becomes located at an opposite end of the slot 2812 in the clamp cam 2806 as shown in
With the dispensing device 2700 in the position and/or configuration shown in
With further anticlockwise rotation of the pulley 2808 and clamp cam 2806 using the motor 2814, the pin 2810 on the rotatable is located at the first end of the slot 2812. The clamp cam 2806, therefore, cannot undergo anticlockwise rotation relative to the rotatable frame 2802. Instead, both the clamp cam 2806 and the rotatable frame 2802 rotate in an anticlockwise direction. The rotation of the rotatable frame 2802 and a container 300 mounted therein can be used to dispense goods from the container 300 through the lid 304 of the container 300 in a controlled manner. The chute 2836 in the upper clamp portion 2830 directs the goods being dispensed from the container.
The hopper 3100 includes a sensor 3102 that detects whether the contents 3104 of the hopper 3100, which have been dispensed from the container 300, have reached a certain level in the hopper 3100. The sensor 3102 may comprise, for example, an optical sensor, proximity switch, and/or some other suitable sensor. The sensor may be used, for example, to control the electric motor 2814 to maintain a sufficient level of the contents 3104 of the container. This may be achieved, for example, by rotating the rotatable frame 2802 and the container 300 further in an anticlockwise direction, relative to the fixed frame 2800 to dispense more contents of the container 300 into the hopper 3100. The rotation may be halted when the sensor 3102 detects that the contents 3104 of the hopper 3100 have reached a sufficient level.
Once all of the contents of the container 300 have been dispensed, or no further contents are required and the container 300 is to be removed from the dispensing device 2700, the rotatable frame 2802 and container 300 are rotated in a clockwise direction relative to the fixed frame 2800, using the motor 2814, to return the dispensing device 2700 to the position and/or configuration shown in
If a container 300 that is removed from the dispensing device 2700 contains contents and a liner, the liner may be sealed using the sealing means 1904 in the lid 304, as described above.
The dispensing device 2700 may be used, for example, to dispense bottle closures such as bottle caps from the container 300. However, it may be used to dispense any other contents of the container 300, with or without a liner in the container 300.
