FIELD OF THE INVENTIONThis invention generally relates to the art of dispensers and, particularly, to a condiment dispenser.
BACKGROUND OF THE INVENTIONThe ability to dispense a controlled quantity of a condiment, such as ketchup, mustard, relish, mayonnaise, salad dressings, hot wings sauce, spaghetti sauce, tartar sauce or other sauces, in an efficient manner has been important in the food service industry for many years. This is especially true for large volume food handling operations such as fast food restaurants, where employees and customers desire the ability to dispense condiments quickly and conveniently, and where even a marginal reduction in the waste of, or time required to dispense, condiments leads to significant savings in cost.
Dispensing condiments from large, flexible plastic bags is advantageous. Condiments can be easily packaged in large plastic bags at a central facility and shipped to the point of sale. Bulk plastic containers can incorporate gas barriers that allow condiments to be packaged so that they can be stored at room temperature, which makes the packages more convenient to ship and store. Storing the condiments at room temperature saves time when it is desirable that the condiment be served at room temperature by eliminating the requirement that the condiment be allowed to warm from a refrigerated temperature before use.
Flexible plastic bags are a common form of packaging for food and thus are readily handled by employees without special training. Further, storing the condiments at room temperature reduces the expense of refrigeration. In addition, bags are often more cost effective, easier to dispose of, and occupy less storage space.
Historically, many products and condiments have been shipped and stored in tin cans, often #10 tin cans. While tin cans offer good shelf life performance, tin cans contribute to waste of product that clings to the side of cans. Further, tin cans are heavy to ship, store, and are heavy and voluminous for disposal. Additionally, tin cans require can openers to open - retrieving the opener reduces operational speed, and the opener may be difficult to locate, further reducing efficiency. Opening tin cans may also result in sharp edges that may tear garbage bags and pose a laceration risk.
Other historical containers include gallon jugs and caulk cartridge type cans. However, gallon jugs contribute to waste in the same fashion as tin cans, and share many of the negative attributes of tin cans. Caulk cartridge type cans leave less product in the canister, but require priming of each can and generate significant wasted product. For example, a 25-ounce cartridge delivering a one-ounce payload necessarily wastes 4% of the product due to priming.
Devices attempting to efficiently dispense condiments from bulk flexible plastic bags exist, including devices that use rollers advanced by gravity, by gears or rack and pinion means to squeeze condiment out of the plastic bags, but these devices have several disadvantages. Devices that use gravity actuated rollers or gears are complicated to manufacture and may involve manipulating the rollers in non-intuitive ways. Other devices that utilize more complex means for releasing condiment from the bags require that the bags incorporate specially designed fittings, including tubes and couplings, which increase the cost and complexity of the packaging and add to product waste during cleanup. Yet other devices use motorized pumps that require electricity and possibly pressurized gases to operate, which adds to the cost and size of the dispensers, increasing manufacturing costs and adding complexity during cleaning. Further, pumps may result in undesired splatter, which both wastes product, as well as work effort to clean the splatter. If a pump in the front of the store splatters, customers may become unhappy. Motorized devices often require long tubes that contribute to waste of the condiment and complicate clean up. Furthermore, existing types of dispensers have a single outlet for the condiment, which reduces efficiency at workstations where multiple outlets can be accommodated. Additionally, tubes reduce the range of movement and freedom of motion of the applicator device. Additionally, devices using pressurized gas rely on the gas, and in event of gas malfunction, or lack of gas supply, the device is non-functional.
Other devices utilize fitments that require significant expense, and contribute to waste if the fitment is improperly fitted. For example, a plastic fitment is used to provide a valve to a flexible bag. For use, the fitment must be separately manufactured, and heat sealed to a flexible bag.
However, accurately fitting a flexible bag into any of these dispensers has been problematic. An appropriate fit of the bag within a dispensing device is important to ensure correct insertion, as well as minimizing waste and potentially damaging the package during use. It is further desirable to minimize the time required to insert the bag, while simultaneously increasing the accuracy of the insertion. It is also desirable to provide a bag that minimizes clean up and disposal costs. It is further desirable that the bag can be manufactured on a variety of packaging machines with the insertion of customized seal jaws to create spouts, locator pins and tear notches.
The present invention advances the art.

In the embodiment illustrated in
In the embodiment illustrated in
Spout receiving portion 93 is configured to dispense the product contained within product containment portion. In one embodiment, spout receiving portion 93 is configured to mate with a spout 505 (see
Top sealed support portion 94 is configured to provide a region for support. In one embodiment, top sealed support portion 94 is configured to be supported by top 22. In another embodiment, roller frame 40 provides sufficient support when in a closed configuration. In one embodiment, top sealed support portion 94 is at an end of the food product containment portion opposite the lower sealed region 95.
In one embodiment, bag 90 is constructed of a flexible plastic capable of preserving the condiment at room temperature. In another example, bag 90 is a barrier bag. At least one of edges of the bag 94, 95, 91 are heat-sealed, and one or more openings spout receiving portions 93 are molded into the lower sealed region. In one embodiment, bag 90 comprises a flexible food grade plastic. In one embodiment, the bag comprises a bi-axially oriented nylon material laminated to an ethyl-vinyl-alcohol (EVOH) polyethylene or metallocene sealant. In another embodiment, the bag comprises a uni-axially oriented nylon or polypropylene laminated to an EVOH and then laminated to a linear low-density polyethylene (LLDPE) or metallocene sealant. Alternatively, the uni-axially oriented polypropylene or nylon can be laminated to a 5 to 7 layer EVOH—LLDPE sealant. In another embodiment, bag 90 comprises PVC, polystyrene, or high-impact styrene. Other embodiments include the use of linear low density blends as well as low density EVA blends.
In another embodiment, bag 90 is composed of a laminated material that provides uniform and consistent tearing properties at least in the region adjacent to and including the at least one spout receiving portion 93. One exemplary embodiment of bag 90 having uniform and consistent tearing properties is composed of a three-ply laminated film. A first layer of the three-ply film is composed of 100 gauge (1 ml) uniaxially oriented polypropylene.
The first layer is laminated to a second layer composed of 50 gauge (0.5 ml) biaxially oriented ethyl-vinyl-alcohol (EVOH). The second layer is laminated to 250 gauge (2.5 ml) linear low-density polyethylene.
In another embodiment, tear strip 96 is configured to include at least one locating hole to further guide tearing of the bag.
Another exemplary embodiment of bag 90 having the uniform and consistent tearing properties is composed of a two-ply laminated film. A first layer of the two-ply film is composed of 100 gauge (1 ml) uniaxially oriented polypropylene. The first layer is laminated to a second layer composed of 300 gauge (3.0 ml) EVOh/polyethylene.
In an exemplary embodiment, the system as described herein may be used to dispense condiments both in the “front of the store” and in the “back of store” using identical bags 90. Operation of the system entails providing a system 10 and a bag 90 containing product to be dispensed through the system 10. Roller assembly 40 is operated to configure roller assembly 40 into an open configuration. An upper portion of bag 90 is inserted between rollers 43, 44 such that the majority of product is located between the rollers 43, 44 and the lower sealed region 95. Roller assembly 40 is then operated to configure roller assembly to a closed and locked configuration. Roller assembly 40 is placed adjacent top clip 30, and if sufficient material of bag 90 is available for insertion into top clip 30, top clip 30 is operated to assume an open configuration, at least a portion of the sufficient material is placed between the arms of top clip 30 and top clip 30 is then operated to assume a closed configuration. Valve assembly 50 is operated to assume an open position and the lower sealed region 95 is placed between front 51 and back 52, such that at least one spout receiving portion mates with at least one valve 53, and the valve 53 is located between any tear strip 96 and the spout receiving portion. In embodiments with bag alignment indicators, the bag alignment indicators 59, 97 are also aligned. Valve assembly 50 is then operated to assume a closed, and locked, configuration.
An operator may choose to ensure that valve 53 is in a closed configuration such that the product containment portion 92 is insulated from the tear strip 96. Tear strip 96 is then torn, or a lower sealed portion is cut such that if valve 53 assumes an open configuration, product disposed in product containment portion 92 may be dispensed from the bag into the desired receptacle. In one embodiment, product is dispensed into a container, such as, for example, the container described in
In another embodiment, bag 90 is loaded into assembly 10 by first opening the top clip and bottom, valve assembly. The rollers remain closed and in a substantially parallel configuration. The bag is positioned over the tangs and bag locators, and the valve assembly is closed over the bag. The top portion of the bag is fed through the rollers until a nip is formed. Once the nip is formed, a sufficient portion of the bag is available to clip into top clip. Having fully supported the bag, the bottom of the bag is torn or cut off to enable dispensing of product from the bag into a dispenser.
The reservoir 311 has an open top 320, sides 321, and a bottom 322. In one embodiment, the reservoir 311 is generally cylindrical, and the top 320 has a larger diameter than the bottom 322. In some embodiments, the top 320 is sized to facilitate easy refilling of the reservoir 311. In another embodiment, the dispenser 310 is substantially frusto-conical. Optionally, a cover (not shown) can be placed over the top 320 to reduce the likelihood of foreign matter failing into the reservoir 311. Additionally, a cover may reduce dehydration of the contents of the reservoir.
The reservoir 311 is made, in one embodiment, of a single piece of a plastic that does not react with food products, is durable, and is easy to clean. In another embodiment, the reservoir 311 is constructed from a plurality of pieces that may be molded together or formed using any appropriate fabrication technique. In another embodiment, reservoir 311 comprises a high density polyethelene (HDPE) or other food grade plastic that is resistant to the contents of the reservoir. The embodiment shown in
In one embodiment, handle 313 actuates pump 312. Actuation of pump 312 controls the flow of condiment from the reservoir 311. The handle 313 includes a fixed component 331 and a movable trigger 332, as shown in
The trigger 332 is functionally connected to the pump 312, and it is located on the handle 313. In one embodiment, an operator can hold the dispenser 310 and actuate the pump 312 with one hand. Several alternative structures exist that would perform the function of the trigger 332, but the trigger 332 shown in the drawings includes a lower arm 333, an axle 334, and an upper arm 336. The lower arm 333 extends below the fixed component 331 of the trigger 332 and between the fixed component 331 and the reservoir 311, where an operator can apply force to the lower arm 333 and actuate the trigger 332. Axle 334 operably and rotatably connects trigger 332 with fixed component 331. In one embodiment, axle 334 is substantially cylindrical and rotates within bearing pockets formed in the fixed component 331 of the handle 313. In one embodiment, the bearing pockets are substantially the same diameter as axle 334. In one embodiment, the bearing pockets are slotted to allow for removal of the arm. Upper arm 336 extends from axle 334 to the topmost element of the pump 312. When force is applied to lower arm 333 of trigger 332, trigger 332 rotates about the axle 334, moving upper arm 336 downward, and actuating pump 312. In the embodiment illustrated in
In one embodiment, trigger 332 is configured so that the pressure applied to trigger 332 determines which of at least two volumes of product is released. For example, a two position trigger may dispense 5 grams of product if 5 foot pounds of pressure is applied to the trigger, and dispense 9 grams of product if more than 6 foot pounds of pressure is applied. The configuration actuates the pump to dispense a default volume of product, i.e. 5 grams in the above example, or a larger volume if desired. Such a configuration may be desirable, for instance, if two similar products are to receive the product. For example, a restaurant may serve two similar hamburgers—a hamburger featuring a quarter pound of hamburger and a hamburger featuring a half pound of hamburger. In this example, the quarter pound hamburger may receive a smaller volume of ketchup than the half pound hamburger, and this may be selected by the amount of force applied to the trigger. In one embodiment, the configuration of trigger 332 comprises a spring loaded stop block, such as female block assembly 391.
In one embodiment, fixed element 331 includes a female block assembly 391 configured to communicate with a male block assembly 390 of trigger 332. Male block assembly 390 mates with female block assembly 91 to stop trigger 332 in an actuated position.
Pump 312 comprises an upper column, a lower column, a piston 342 and a cylinder 343. As shown in
A vertical wall extends around the circumference of the bottom. Opening 345 is sized to accept bottom 347 and vertical wall 344, and is configured so that the edge of the vertical wall 344 connects with the edge of the piston 342. In operation, the vertical wall 344 forms an interface with the opening 345 of the piston 342 when trigger 332 is squeezed. Wall 344 severs or compresses any particulate matter that would interfere with an interface between upper column 340 and the piston 342. In one embodiment, vertical wall 344 is thinner than the reservoir 311.
Piston 342 rests in the upper chamber 348 of the pump cylinder 343, as shown in
Pump cylinder 343 rests at the bottom of the reservoir 311. In one embodiment, pump cylinder 343 is sized to form an interface between the exterior of the cylinder 343 and the bottom of the reservoir 311. In one embodiment, the interface created between the exterior of cylinder 343 and the bottom of reservoir 311 prevents the condiment from leaking around the cylinder. In addition to the upper chamber 348, described above, pump cylinder 343 includes a lower chamber 350 and a partition 351 that separates the upper chamber from the lower chamber. Like the piston 342, the partition 351 has a central hole 352 through which the lower column 341 extends and a plurality of holes 353. In one embodiment, the holes 353 are chamfered to remove sharp edges at the top and bottom surfaces of the partition. A cylindrical vertical wall 354 extends below the partition 351 and forms an interface with the bottom plate 355 of the lower column 341. In one embodiment, vertical wall 354 is thinner than the walls of the reservoir 311. In operation, the vertical wall 353 severs or compresses any particulate matter in the condiment, thereby improving the interface between the pump cylinder 343 and the bottom plate 355 of the lower column 341.
As shown in
The operation of the embodiment of the invention shown in
On actuation of trigger 332, the vertical wall 344 moves downward and engages with wall 345 of the piston 342, forming an interface that prevents further condiment from flowing into the upper chamber 348. The action of the trigger 332 also moves the lower column 341 downward, which forms a gap between the bottom plate 355 and the pump cylinder 343 due to pressure of the condiment, permitting condiment in the upper chamber 348 to flow through the holes 353 of the pump partition 351 and out the holes 323 in the bottom 322 of the dispenser. Further action of the trigger 332 depresses the piston 342, thereby forcing the condiment in the upper chamber 348 out of the dispenser.
When the trigger 332 is released, lower column 341 moves upward as biased by the lower spring, restoring the interface between the bottom plate 355 and the vertical walls 354 of the pump cylinder 343. The upper plate 356 engages the piston 342 and moves piston 342 upward to its original position near the top of the upper chamber 348. The upper column 340 is biased upward by the upper spring, restoring the gap between the piston wall 345 and the vertical wall 344. In this position, condiment flows into the upper chamber 348 but not the lower chamber 350, and the dispenser 310 is ready to be used again.
A container in accordance with the embodiments illustrated in
Dispenser 1400 includes a trigger 1405 operably connected to rod 1410. In one embodiment, trigger 1405 is manufactured as a unitary piece, including protrusions configured to mate with holding gaps 1407 manufactured into a receptacle 1408 of grip 1409. Grip 1409 further includes stop block 1475. Stop block 1475 is configured to control the distance that can be traveled between trigger 1405 and grip 1409. In one embodiment, stop block 1475 is removable and configured to control the amount of product dispensable with dispenser 1400. For example, one stop block is configured to allow trigger 1405 to displace a certain distance to dispense 5 grams of product. In another example, a different stop block is configured to allow trigger 1405 to displace a different distance to dispense 3 grams of product. In another example, stop block 1475 is configured with a spring load to enable multiple levels of product dispensing. For example, a spring loaded stop block is configured so that displacing trigger 1405 until the handle meets the resistance from the spring dispenses 5 grams of product, while continuing the displacement and overcoming the spring resistance results in dispensing 7 grams of product. In other embodiments, stop block 1475 is configured to mount to trigger 1405.
Trigger 1405 is configured to slide through receptacle 1408, such that when properly assembled trigger 1405 is disposed between handle portion 1409 and the body of container 1420. This configuration is illustrated in FIGS. 17 (trigger 1405 in a non-deployed position) and 18 (trigger 1405 in a deployed position). Operation of trigger 1405 moves handle closer or farther away from a lower surface 1498. In other words, if a human holds dispenser 1400 in their right hand, in a ‘hand-shaking’ fashion, the user's fingers surround trigger 1405 while a palm of the hand surrounds grip 1409. Application of pressure by the user's fingers moves the trigger 1405 about axis 1493 and closer to handle portion 1409 in “gripping” fashion. In one embodiment, trigger 1405 includes finger guard 1404 configured to facilitate handling dispenser 1400. In another embodiment, trigger 1405 includes rest position blocks 1401 configured to limit trigger upstroke.
Dispenser 1400 includes a container 1420. Container 1420 includes a containment portion 1421 configured to hold product within dispenser 1400. Container 1420 further includes grip 1409, and at least one wing 1423. In one embodiment, wing 1423 is configured as a protrusion extending outward from an outer wall of the containment portion 1421 and substantially perpendicular to an axis extending through a centerline 1426 of the product area. In one embodiment, the at least one wing 1423 is shaped to mate with a wing receptacle of a dispenser support (
Trigger 1405 is configured to rotate about an axis 1493 between the protrusions when fitted into the gaps 1408. Thus, in operation, trigger 1405 rotates about axis 1493 to bring trigger 1405 closer or farther from grip 1409. Trigger 1405 is, in one embodiment, configured to actuate the dual knife blade pump assembly.
Dispenser 1400 further includes a removable cap 1430. In one embodiment, removable cap is configured to be screwed on to a cap portion 1431 of container 1420. In other embodiments, the removable cap may be attached to the cap portion by a snaps, hinge, rivets, pins or bayonet style attachment devices. Cap 1430 includes a top surface 1432 and bottom surface 1433. Top surface 1432 is configured to be in contact with product prior to dispensing the product, while bottom surface 1433 is opposite top surface 1432. Cap 1430 includes at least one hole 1437 (
Trigger 1405 operably connects to rod 1510. In one embodiment, trigger 1405 attaches to rod 1510 with a snap, although other connection methods are anticipated and included in this disclosure. Rod 1510 includes a lower region 1513. Lower region 1513 includes first knife blade receptacle 1520. First knife blade receptacle 1520 is configured to mate with first knife blade 1530. In one embodiment, first knife blade receptacle 1520 is a chamfered surface formed in lower region 1513 and configured to closely meet with first knife blade 1530. First knife blade 1530 and first knife blade receptacle 1520 forms an upper knife blade assembly. Manufacturing tolerances for the upper knife blade assembly should be tight, as engagement between first knife blade 1530 and first knife blade receptacle 1520 is especially beneficial for the invention. It should be noted that although metallic knife blades may be used to create a relatively sharp knife edge, metallic knife edges are not necessary, and first knife blade 1530 and first knife blade receptacle 1520 may be molded from plastics or other material as a unitary part.
Piston 1540 includes first knife blade 1530 and includes at least one product opening to allow product to flow from around rod 1510 and through piston 1540 to cylinder 1550. In one embodiment, each product opening is chamfered to minimize the number of surfaces with a plane perpendicular to an axis 1501 running through a centerline of dual knife blade pump assembly 1440. Piston 1540 slides along pin 1543. In one embodiment, pin 1543 is made as unitary construction with rod 1510, while in other embodiments, pin 1543 is a separate piece configured for operable attachment to rod 1510. Although pin 1543 is shown in
It should be noted that first knife blade 1530 could be disposed upon rod 1510 and that first knife blade receptacle 1520 could be configured on piston 1540, and that such a configuration is considered the equivalent.
First knife blade 1530 is disposed on an upper surface 1531 and configured to mate with first knife blade receptacle 1520. Piston 1540 further includes a lower surface 1532 including an upper spring seat 1537. As shown in
Cylinder 1550 surrounds spring 1545 and is operably disposed within product portion 1495 of
Valve 1570 displaces along axis 1501 to dispense product, guided by valve guide 1565. Valve 1570 further includes second knife blade receptacle 1590 and bottom spring seat 1595 configured to provide a surface for spring 1575. The combination of second knife blade 1580 and second knife blade receptacle 1590 forms a lower knife blade assembly. The upper knife blade assembly and lower knife blade assembly form a dual knife blade assembly. Manufacturing tolerances for the lower knife blade assembly should be reasonably tight, as engagement between second knife blade 1580 and valve knife blade receptacle 1590 is especially beneficial for the invention. It should be noted that although metallic knife blades may be used to create a relatively sharp knife-edge, metallic knife-edges are not necessary, and second knife blade 1580 and second knife blade receptacle 1590 may be molded from plastics or other material as a unitary part.
It should be noted that second knife blade 1580 could be disposed upon valve 1570 and that second knife blade receptacle 1590 could be configured on cylinder 1550, and that such a configuration is considered the equivalent.
Operation of dispenser 1400 is described as follows, referencing
When dispenser 1400 has no product contained in cylinder 1550, the dual knife blade pump assembly must be primed for its first use. It should be noted that so long as the amount of product in containment portion 1421 does not fall below a certain “minimum level,” no further priming is necessary until dispenser 1400 is emptied of product again, such as for cleaning.
Priming the dual knife blade pump assembly comprises filling cylinder 1550 with product. Prior to priming, trigger 1405 sits at rest in a non-deployed position. Actuation of trigger 1405 to operate dispenser 1400 moves trigger 1405 closer to grip 1409. Movement of trigger 1405 displaces rod 1510 axially along axis 1501. When rod 1510 is at its uppermost position (trigger 1405 is in its non-deployed position), product in containment portion 1421 flows around lower region 1513 and through holes 1531, filling cylinder 1550 with product. When space in the pump assembly has been filled with product, the dual knife blade pump assembly is said to be primed.
After priming, dispenser 1400 is set to dispense product. Dispenser 1400 is shown in a configuration ready to dispense product in
Having dispensed the product contained within cylinder 1550, trigger 1405 returns to its non-deployed position, displacing rod 1510 in direction B. Displacement of rod 1510 effectively breaks the interface between first knife blade receptacle 1520 and first knife blade 1530. The removal of the force applied in direction A removes the forces from spring 1545 and dispensing the product reduces the forces from spring 1575, allowing each spring to unload its loaded force, biasing rod 1510 in direction B. Unloading spring 1575 moves valve 1570 in direction B until second knife blade 1580 and second knife blade receptacle 1590 meet. The contact between second knife blade 1580 and second knife blade receptacle 1590 creates an effective seal, and effectively or substantially compresses or severs any particulate that is disposed between the complementary surfaces second knife blade 1580 and valve knife blade receptacle 1590. Product then flows into cylinder 1550, as valve 1570 has closed, and piston 1540 has separated from cylinder 1550 moving through the product, creating a gap between first knife blade receptacle 1520 and first knife blade 1530.
When dispensing relatively viscous products, suck back created by movement of the piston 1540 assists in moving the valve and releasing forces from spring 1575. Additionally, suck back will assist in reducing undesired product drip from the removable cap and/or bottom openings.
During operation as described herein, when the valve is open, the first knife blade 1530 engages with first knife blade receptacle 1520. Conversely, when the valve is closed, the second knife blade 1580 engages with second knife blade receptacle 1590. In one embodiment, engagement between the respective knife blades and knife blade receptacles creates a seal.
In one embodiment, stop block 1475 and cap 1430 are a matched pair, such that stop block 1475 is configured to be removable from grip 1409. For example, both stop block 1475 and cap 1430 are colored red for a dispenser configuration to dispense ketchup. In another example, both stop block 1475 and cap 1430 are colored white for a dispenser configuration to dispense tartar sauce. In other embodiments, stop block 1475 and cap 1430 are inscribed with writing to indicate either a product to be dispensed, or an amount of product to be dispensed. In another embodiment, the trigger is configured to actuate the pump assembly. In yet another embodiment, the trigger includes a stop block configured to control the amount of product dispensed with a single pump actuation.
In another embodiment, stop blocks 1475 are a portion of the trigger, and the triggers are matched to the removable cap.
