This invention generally relates to dispensers for dispensing food products. More particularly, the present invention pertains to a condiment dispenser for dispensing desired amounts of condiment from a condiment-containing receptacle.
Various types of food service establishments such as restaurants and fast food facilities serve a variety of food items. With at least some of the food items, patrons oftentimes prefer to consume the food item accompanied by one or more condiments. These condiments include ketchup, mustard, mayonnaise, relish and possibly others.
These condiments are sometimes served or provided to the patrons in individual serving packages. Another approach involves providing containers of condiments from which customers can obtain the desired amount of condiment. For example, some fast food establishments provide canisters of different condiments, each provided with a hand operated pump dispenser. In the case of this latter approach, food service establishments oftentimes find it more cost-effective to purchase rather large, industrial size containers of condiments from condiment suppliers. From these large containers, the food service establishment fills the smaller containers (e.g., the pump dispenser canisters mentioned above) which are made available to the patrons for individual dispensing and consumption. Food service establishments might also dispense a quantity of the condiment into a smaller container for use in dressing food items (e.g., sandwiches, hamburgers, etc.).
In the past, larger quantities of condiments have been packaged in bags which are used by food service establishments and the like in the manner described above. The bags are provided with an exteriorly threaded tube that communicates with the interior of the bag. A removable cap covers the tube to ensure that the contents of the bag do not flow through the tube prior to use (e.g., during shipment and storage). To dispense the condiment, the cap is removed and a spout is connected to the tube by threadably engaging an interiorly threaded ring on the spout with the exteriorly threaded portion of the tube. The spout includes an outlet end and a plastic element covering a hole provided in the spout. The plastic element is connected to a manually operated lever. By manually pressing the lever, the plastic element is moved away from the hole in the spout so that condiment in the bag can flow by gravity through the hole and out of the outlet end of the spout. Upon releasing the lever, the plastic element automatically returns to its initial position covering the hole in the spout to stop further flow of condiment.
While it may be cost efficient to purchase large industrial size quantities of condiments, these approaches also present certain drawbacks. For example, condiment in the large container is not easily dispensed into the smaller containers for use by patrons. Also, difficulties may be created with respect to storing the condiment in the large container after a portion of the condiment has been dispensed into the smaller container. In the case of the bags mentioned above, as the condiment is dispensed from the spout, the condiment can adhere to the inside surface of the spout and accumulate over time which may not be desirable. In addition, the spout is specifically designed to be removable so that once the bag is emptied to the extent possible, the spout is removed and attached to another bag. This can create difficulties as the user may forget to remove the spout before discarding the emptied bag. Also, the spout must be cleaned prior to reuse to remove accumulated condiment on the interior of the spout. Also, it has been found to be somewhat difficult to completely empty the bag and so useful condiment may be discarded with the bag.
A condiment dispenser is comprised of a holder having walls which together define an interior of the holder, and a condiment container having an interior containing a quantity of an edible food condiment. The condiment container is provided with a dispensing nozzle through which the condiment in the condiment container is dispensed from the condiment container. The condiment container is adapted to be positioned in the interior of the holder with the dispensing nozzle accessible from outside the holder so that the condiment can be dispensed from the condiment container. The condiment dispenser also includes a shaft on which the condiment container is adapted to be wound to apply pressure to the condiment in the condiment container to dispense the condiment through the dispensing nozzle.
According to another aspect of the invention, a condiment dispenser for dispensing condiment from a condiment containing bag through a dispensing nozzle provided on the condiment containing bag comprises a holder having a plurality of upright walls surrounding an enclosed space in the holder which is adapted to receive the condiment containing bag so that the dispensing nozzle of the condiment containing bag is accessible rom outside the holder, and a shaft rotatably mounted at the holder and on which the condiment containing bag is adapted to be wound to apply pressure to the condiment in the condiment containing bag and thereby dispense the condiment in the condiment containing bag through the dispensing nozzle. A handle is connected to the shaft to rotate the shaft so as to wind the condiment containing bag on the shaft and apply pressure to the condiment in the condiment containing bag causing the condiment to be dispensed from the dispensing nozzle.
Features and details associated with the present invention will become more apparent from the following detailed description considered with reference to the accompanying drawing figures in which like reference numerals designate like elements.
Referring initially to
The condiment-containing bag is also provided with a dispensing nozzle 14 for dispensing condiment in the bag. In the embodiment of the condiment-containing bag illustrated in
The cylindrical spout 18 is provided with a valve 20 positioned near the open end of the spout 18 that is remote from the flange 16. In the illustrated embodiment of the dispensing nozzle 14 shown in
The plastic membrane forming the valve 20 can be in the form of a silicone membrane, although other plastic materials such as polypropylene can be employed. Also, in the illustrated version, the plastic membrane forming the valve 20 includes two slits that intersect one another, although other numbers of slits may be employed depending upon, for example, the flow characteristics desired and the type of condiment.
The dispensing nozzle 14 can also be provided with a peelable seal 24 that covers the remote end of the cylindrical spout 18 to thus cover the valve 20 prior to first use. To dispense condiment from the condiment-containing bag the first time, the peelable seal 24 is removed to expose the valve 20.
Turning back to
The front wall 32 of the bag holder 30 is provided with a vertically extending through slot 38. The nozzle 14 of the condiment-containing bag 10. 10′ projects through the bottom portion of the slot 38 in the manner shown in
The bag holder 30 is preferably made of lightweight material such as plastic (e.g., ABS or other plastic materials suitable for the purpose) and is adapted to be mounted on a vertical wall or other suitable vertical structure. This can be accomplished by providing the bag holder 30 with an appropriate mounting mechanism. For example, the rear wall 34 of the bag holder 30 can be outfitted with a pair of cut-outs adapted to receive mounting pegs, hooks or the like affixed to and extending from the wall or other vertical surface Alternatively, the bag holder 30 can be provided with hooks adapted to engage a mounting bar or other suitable structure. The bag holder 30 can thus be mounted at a suitable position so that the overall condiment dispenser is positioned at a location which facilitates its use.
Each of the side walls 36 of the bag holder 30 is provided with a vertically extending slot 40. As will be described in more detail below, these slots 40 in the side walls 36 receive a portion of the pressure applying mechanism for applying pressure to the condiment in the condiment-containing bag.
The pressure applying mechanism 50 is comprised of a shaft 52 supported in a pair of slidable brackets 54. The shaft can be made of metal (e.g., stainless steel), plastic or other suitable material acceptable for the environment. Each of the brackets 54 is mounted in the slot 40 in one of the side walls 36 of the bag holder 30 and is capable of sliding along the length of the respective side wall 36. As best illustrated in
The shaft 52 is rotatably supported in the brackets 54 and extends across the interior of the bag holder 30. The condiment-containing bag 10, 10′ is adapted to be wrapped around the shaft 52. If desired, an appropriate mechanism can be provided to fix the end of the bag to the shaft 52 to prevent the condiment-containing bag from becoming separated from the shaft 52. By way of example, the shaft 52 can be provided with a slot in which is positioned the end of the condiment-containing bag.
The pressure applying mechanism 50 further includes a ratchet 56 and a pawl 58 positioned adjacent one side of the bag holder 30. The ratchet 56 is fixed to the shaft 52 so that the ratchet 56 and the shaft 52 rotate together as a unit, while the pawl 58 is mounted on the bracket 54. The tip of the pawl 58 engages the teeth on the ratchet 56 in a way that permits rotation of the shaft 52 in one direction (e.g., the counterclockwise direction as seen from the right end of the shaft 52 in
The pressure applying mechanism 50 further includes a handle or lever 60 that is mounted at or fixed to a housing 70. The handle 60 is operatively engageable with the shaft 52 in such a way that when the handle 60 is rotated in one rotational direction, the shaft 52 rotates together with the handle 60 and when the handle 60 is rotated in the opposite rotational direction, the handle 60 rotates relative to the shaft 52.
As shown in
Of course, it is to be understood that the condiment-containing bag can be wound on the shaft 52 in the opposite direction, in which case the handle 60 is operated in the direction opposite to that described above to dispense condiment from the condiment-containing bag 10, 10′.
To use the condiment dispenser illustrated in
To secure the flexible condiment-containing bag 10, 10′ to the shaft 52, the top end of the flexible 10, 10′ is wrapped around the shaft 52, possible being secured to the shaft 52 in an appropriate manner as mentioned above. This can be accomplished either before or after the bag is placed in the bag holder 30. In addition, the peelable seal 24 on the end of the dispenser nozzle 14 is removed to expose the valve 20. The condiment dispenser is now ready for use.
When an individual is interested in dispensing condiment from the condiment-containing bag, such as for filling a small container for use by patrons or others, the handle 60 is rotated in the appropriate direction to further wind the flexible condiment-containing bag 10, 10′ on the shaft 52 and increase the pressure within the bag. Referring to the condiment dispenser shown in
The valve 20 of the dispensing nozzle 14 is designed to remain closed until the pressure within the condiment-containing bag 10, 10′ reaches or exceeds a predetermined pressure. This predetermined pressure can be selected by varying characteristics associated with the plastic membrane such as its thickness, material and rigidity, and the arrangement and number of slits 22 provided in the plastic membrane. Once the pressure in the flexible bag equals or exceeds the predetermined pressure value, the valve 20 automatically opens and condiment is dispensed through the dispensing nozzle 14.
Once the desired amount of condiment has been dispensed, the handle 60 is released, thus preventing further increase in pressure within the condiment-containing bag 10, 10′. When the handle 60 is released, the pawl 58 engages the ratchet 56 to prevent reverse rotation of the handle 60 in the opposite direction. Once the handle 60 is released, the pressure within the condiment-containing bag no longer exceeds the predetermined valve opening pressure. The valve 20 thus automatically closes and prevents additional condiment from being dispensed.
By successively operating the handle 60 in this manner, the desired amount of condiment can be dispensed, with the valve 20 automatically closing each time the handle 60 is released. As the condiment in the condiment-containing bag is dispensed, more of the bag becomes wound on the shaft 52. As this occurs, the pressure applying mechanism 50 is able to move downwardly relative to the bag holder 30 by virtue of the sliding or bearing engagement between the brackets 54 and the side walls 32 of the bag holder 30. The bag 10, 10′ thus continues to rest on the bottom of the bag holder 30.
Also, as mentioned above, it is possible to reposition the handle by rotating the handle 60 in the direction which is opposite the direction causing condiment to be dispensed from the bag. The user is thus free to position the handle at a desired position for dispensing condiment.
Once all of the condiment has been dispensed from the condiment dispenser, the empty bag 10, 10′ can be simply unwound from the shaft 52 and discarded, and replaced by a new filled condiment-containing bag. Thus, with this construction, the entire condiment-containing bag is disposable, including the nozzle with the valve.
The condiment dispenser here is thus able to dispense condiment in the desired amount in a relatively easy manner. The opening of the valve 20 to initiate dispensing occurs automatically when the handle 60 is rotated. Similarly, the closing of the valve 20 to stop dispensing occurs automatically by simply releasing the handle 60. This provides easy control of the dispensing operation as well as the amount of condiment dispensed. The wall dispenser is also versatile in that it can be mounted in a variety of locations to suit the user.
