A pickling device for meat product production

Abstract

This invention discloses a marinating device for meat product production, relating to the field of food marinating technology. The device includes a marinating box with a marinating trough inside its side wall, connected to the outside via a feeding port. Multiple meat racks are rotatably mounted in layers inside the box, each rack connected to a folding mechanism via a rotating column. When a meat rack unfolds from a vertically folded state to a horizontally folded state, the rotating column drives the folding mechanism to unlock the limit of the previous meat rack and simultaneously triggers a connecting mechanism, allowing the interior of the meat rack to connect with the marinating trough. The meat rack contains a hollow meat-holding tube; in the unfolded state, its upper and lower end faces have through holes that allow the marinade to evenly contact the surface of the meat, achieving layered and efficient marinating and avoiding the problem of insufficient contact between the meat and marinade in traditional stacked marinating methods. The device has an ingenious structure, is easy to operate, and effectively improves marinating uniformity and efficiency.

Description

Technical Field

[0001] This invention relates to food marinating technology, specifically a marinating apparatus for meat product production. Background Technology

[0002] As is well known, marinating is a crucial pre-treatment step in meat processing, typically involving immersing meat pieces in a liquid marinade to infuse flavor, retain moisture, and improve texture. Traditional production often uses fixed marinating boxes, where meat products are stacked and weighed down to promote marinade penetration. While this method is simple to operate, it lacks effective control over the placement of the meat, making it difficult to achieve uniform and efficient marinating results.

[0003] Existing marinating devices generally suffer from simple structures and limited functions: meat products are compressed when stacked, making it difficult for the interior and bottom areas to fully contact the marinade, resulting in uneven marinating; at the same time, they lack layered support and directional marinade delivery mechanisms, making it impossible to operate layer by layer as needed or automatically control the flow of marinade. These problems not only affect the consistency of product quality but also reduce production efficiency, necessitating the development of a new type of marinating device with layered meat placement, intelligent connection of marinade channels, and orderly operation. Summary of the Invention

[0004] The purpose of this invention is to provide a marinating apparatus for meat product production to overcome the aforementioned shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: comprising: a pickling box, wherein a pickling trough is formed inside the side wall of the pickling box, and a feeding port is formed outside the pickling box connecting to the pickling trough; and further comprising:

[0006] Multiple meat racks are installed in a multi-layered, rotating manner on both sides of the marinating box.

[0007] Rotating columns, which are fixedly installed at the bottom ends of both sides of the meat rack;

[0008] The folding mechanism is located on both sides inside the marinating box. The folding mechanism is connected to the rotating column. When the rotating column rotates from the vertical folded state to the unfolded horizontal state, the rotating column passively drives the folding mechanism to unlock the restriction on the previous set of meat racks. At the same time, after the folding mechanism unfolds the meat racks, it passively drives the connecting mechanism to connect the inside of the meat racks with the marinating tank.

[0009] As a further description of the above technical solution: the marinating box has folding grooves on both sides in a multi-layered manner, and a meat rack is rotatably installed in the folding grooves.

[0010] As a further description of the above technical solution: the folding mechanism includes rotating columns fixedly installed at the bottom of both sides of the meat rack, a sleeve is provided at the center of the rotating column, and an insert rod is rotatably inserted into the sleeve, the insert rod being located at the center of the rotating groove.

[0011] As a further description of the above technical solution: the folding mechanism also includes an outwardly protruding ring fixedly disposed on one side of the outer perimeter of the rotating column. The outer surface of the protruding ring is provided with an abutment groove. An abutment ball is slidably connected to the abutment groove. The top end of the abutment ball is fixedly connected to the bottom end of the top rod. The top end of the top rod passes through the movable groove in the side wall of the pickling box and is inserted into the bottom of the rotating groove opened on both sides of the previous set of folding grooves. A limiting plate is fixedly connected to the bottom of the rotating column. The limiting plate is slidably connected to the lower surface of the rotating column.

[0012] As a further description of the above technical solution: when the meat rack is unfolded outward to a horizontal state, the rotation angle of the rotating column is less than or equal to 90°, the size of the convex ring along the rotation direction of the rotating column gradually increases outward, and the arc surface of the convex ring is a quarter circle. The convex ring is rotatably arranged in the rotating rail, and the rotating rail is opened at the connection between the top of the rotating groove and the bottom of the movable groove.

[0013] As a further description of the above technical solution: the connecting mechanism includes a movable sealing plate fixedly installed in the rotating column. The rotating column and the sleeve set at the center position inside are in a cavity shape. Movable sealing plates are symmetrically arranged on both sides of the cavity to connect the outer periphery of the sleeve and the inner sidewall of the rotating column. The interval between the movable sealing plates is a movable drainage hole in a cavity shape. The movable sealing plate at one end of the rotating column inserted into the rotating groove protrudes outward.

[0014] As a further description of the above technical solution: the connecting mechanism also includes fixed sealing plates symmetrically arranged in the rotating groove, the cavity spacing between the fixed sealing plates is a fixed drainage hole, and an elastic sealing plate is movably arranged on the end face of the fixed sealing plate that fits against the movable sealing plate. The elastic sealing plate can be squeezed and contracted along the rotation direction of the rotating column in the unfolded state of the meat rack.

[0015] As a further description of the above technical solution: meat placement tubes are provided at intervals inside the meat placement rack, the meat placement rack and the meat placement tubes are hollow, and when the meat placement tubes are in a horizontal state, through holes are opened at the upper and lower end faces of the meat placement tubes.

[0016] As a further description of the above technical solution: the bottom dimension of the movable groove is adapted to the range of motion of the contact ball, and the position dimension of the top rod inserted at the upper end of the movable groove is adapted to the top rod, so that the top rod and the contact ball can only slide up and down.

[0017] As a further description of the above technical solution: elastic sheets with elastic deformation capability are provided at the top of both sides of the meat rack.

[0018] The marinating apparatus for meat product production provided by the present invention, as described above, has the following beneficial effects:

[0019] 1. Achieve layered marinating and improve marinating uniformity: Through a multi-layered expandable meat rack and hollow meat tube structure, meat products are placed in layers, avoiding the problem that meat in the middle or bottom cannot fully contact the marinade due to traditional stacking.

[0020] 2. Automatic unlocking and layer-by-layer opening mechanism: The folding mechanism design allows the lower meat rack to be passively unlocked after it is unfolded, ensuring that it can only be operated layer by layer from bottom to top, preventing accidental operation and improving safety and logic.

[0021] 3. Intelligent connecting marinade channel: When the meat rack is unfolded, the connecting mechanism operates synchronously, connecting the marinade tank with the meat rack and meat tube. The marinade is applied directly to the surface of the meat through the through holes, improving marinating efficiency.

[0022] 4. Sealing and leak-proof design: The design uses a combination of movable sealing plates, fixed sealing plates and elastic sealing plates to effectively seal the drainage holes and prevent marinade leakage when the meat rack is folded; when unfolded, it is precisely aligned and can be opened, and the structure is reliable.

[0023] 5. Automatic reset and secure fixation: The elastic sheet and elastic sealing sheet can help the meat rack automatically spring back and fold after use, and provide resistance fixation in the storage state, making it easy to organize and store. Attached Figure Description

Detailed Implementation

[0036] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] Please see Figures 1-9 This invention provides a technical solution for a marinating device for meat product production, comprising: a marinating box 1, a marinating trough 4 formed inside the side wall of the marinating box 1, and a feeding port 2 connected to the marinating trough 4 on the outside of the marinating box 1, and further comprising:

[0038] Multiple meat racks 6 are installed in a multi-layered, rotating manner on both sides of the marinating box 1.

[0039] Rotating column 11 is fixedly installed at the bottom of both sides of the meat rack 6;

[0040] The folding mechanism is located on both sides inside the marinating box 1. The folding mechanism is connected to the rotating column 11. When the rotating column 11 rotates from the vertical folded state to the unfolded horizontal state, the rotating column 11 passively drives the folding mechanism to unlock the restriction on the upper set of meat racks 6. At the same time, after the folding mechanism unfolds the meat racks 6, it passively drives the connecting mechanism to connect the inside of the meat racks 6 with the marinating tank 4.

[0041] In another embodiment of the present invention, preferably, the marinating box 1 has folding grooves 5 on both sides in a multi-layered manner, and a meat rack 6 is rotatably installed in the folding grooves 5.

[0042] In the process of marinating meat products, the meat products are usually soaked in liquid marinade and pressed with heavy objects. The meat products are usually stacked as a whole in the marinating box 1. At the places where the meat products are stacked together, due to the compression of a large number of meat products, it is difficult for the marinade to be absorbed, which affects the marinating effect and makes it impossible to marinate the meat products in layers, thereby reducing the amount of meat products stacked in the middle.

[0043] After opening the top cover 3 of the marinating box 1, open the meat racks 6 installed on both sides of the marinating box 1 by folding grooves 5 downwards. First, open the bottom meat rack 6 in the marinating box 1. At this time, the elastic pieces 10 set at the top of the meat racks 6 on both sides will contact each other and gradually open the meat racks 6 downwards to a horizontal position. At this time, the two sets of elastic pieces 10 will press against each other, thus providing a tight connection between the two sets of meat racks 6. After the two sets of meat racks 6 on both sides are in a horizontal position, the meat to be marinated can be placed on the meat tubes 7 set in the meat racks 6. The meat placed at this time will also press down on the meat racks 6 by its own weight. After the meat racks 6 at the bottom are full of meat, the meat racks 6 at the top can be unfolded from the folding grooves 5 and placed in a horizontal position, so that meat can continue to be placed on the top layer. The multi-layer meat racks 6 distributed from bottom to top can only be opened layer by layer from bottom to top, and cannot be opened by skipping layers.

[0044] To achieve the above effect, the specific structures involved include:

[0045] In another embodiment of the present invention, the folding mechanism includes rotating columns 11 fixedly installed at the bottom ends of both sides of the meat rack 6. A sleeve 24 is provided at the center of the rotating column 11, and an insert rod 14 is rotatably inserted into the sleeve 24. The insert rod 14 is located at the center of the rotating groove 9.

[0046] In another embodiment of the present invention, the folding mechanism further includes an outwardly protruding ring 20 fixedly disposed on one side of the outer periphery of the rotating column 11. The outer surface of the ring 20 is provided with an abutment groove 21. An abutment ball 19 is slidably connected to the abutment groove 21. The top end of the abutment ball 19 is fixedly connected to the bottom end of the top rod 16. The top end of the top rod 16 passes through the movable groove 17 in the side wall of the pickling box 1 and is inserted into the rotating groove 9 opened on both sides of the previous set of folding grooves 5. The bottom of the limiting plate 15 is fixedly connected to the limiting plate 15. The limiting plate 15 is slidably connected to the lower surface of the rotating column 11.

[0047] In another embodiment of the present invention, when the meat rack 6 is extended outward to a horizontal state, the rotation angle of the rotating column 11 is less than or equal to 90°, the size of the convex ring 20 along the rotation direction of the rotating column 11 gradually increases outward, and the arc surface of the convex ring 20 is a quarter circle. The convex ring 20 is rotatably arranged in the rotating rail 18, which is opened at the connection between the top of the rotating groove 9 and the bottom of the movable groove 17.

[0048] In another embodiment of the present invention, the bottom dimension of the movable groove 17 is adapted to the range of motion of the abutment ball 19, and the position dimension of the top rod 16 inserted at the upper end of the movable groove 17 is adapted to the top rod 16, so that the top rod 16 and the abutment ball 19 can only slide up and down.

[0049] In another embodiment of the present invention, elastic sheets 10 with elastic deformation capability are provided at the top of both sides of the meat rack 6.

[0050] After the bottom layer meat rack 6 is flipped outward from the folding groove 5, the rotating posts 11 on both sides of the bottom of the meat rack 6 rotate with the meat rack 6, combined with the attached... Figure 7 and 8 As the rotating column 11 rotates, the initial position S1 of the rotating column 11 corresponding to the folded meat rack 6 will gradually switch to the final position S2 of the rotating column 11 corresponding to the horizontal position of the meat rack 6. During the rotation of the rotating column 11, the outward protruding ring 20 on the outer periphery of the rotating column 11 will, due to its own size and the contact groove 21 on its surface, generate an upward force on the contact ball 19. As the ring 20 rotates, it will drive the top rod 16 downward, thereby pulling the limiting plate 15 connected to the top of the top rod 16 downward. Thus, the limiting plate 15, which was originally attached to the outer periphery of the rotating column 11, will separate from the rotating column 11 connected to the upper meat rack 6, thereby releasing the restriction on the rotating columns 11 at both ends of the upper meat rack 6, making it easier to unfold the upper meat rack 6.

[0051] It should be noted that: in conjunction with the appendix Figure 5 The pickling box 1 has movable grooves 17 on both sides that are adapted to the size of the top rod 16 and the abutment ball 19, which can ensure that the top rod 16 slides up and down with the abutment ball 19 without any positional deviation.

[0052] Meanwhile, the elastic sealing sheet 12 itself has elastic deformation capability. After the marinating box 1 is used, after the meat products on the surface of the meat rack 6 are removed, the meat rack 6 only needs to be pulled upward to release the squeezing pressure between the elastic sheets 10. Under the rebound action of the elastic sealing sheet 12, the meat rack 6 will drive the rotating column 11 to rotate and reset, thereby folding the meat rack 6 back into the folding groove 5. The fixed drainage hole 13 and the movable drainage hole 23 between the rotating column 11 and the rotating groove 9 will be misaligned and sealed. At the same time, after the meat rack 6 is folded back into the folding groove 5, the elastic sheet 10 will squeeze the inner wall of the top of the folding groove 5 to fix and restrict the meat rack 6 with a certain resistance.

[0053] The rotating column 11 and the rotating groove 9 are respectively equipped with matching rotating sleeves and rotating rods at their center positions. The rotating rods are inserted into the rotating sleeves to ensure that the rotating column 11 and the rotating groove 9 will only rotate around a fixed center.

[0054] After filling the marinating box 1 with meat, it is necessary to add the prepared liquid marinade to the marinating box 1. The marinade is added into the marinating box 1 through the feeding port 2. After the liquid marinade is added into the marinating box 1 through the feeding port 2, it will flow into the marinade channel 8 in the marinating box 1. The marinade in the marinade channel 8 flows into the meat rack 6 and the meat tube 7 through the folding mechanism, and is discharged through the meat tube 7 to directly contact the surface of the meat products, thereby achieving better marinating of the meat products.

[0055] To achieve the above effects, the specific organizations involved include:

[0056] In another embodiment of the present invention, the communication mechanism includes a movable sealing plate 22 fixedly installed in the rotating column 11. The rotating column 11 and the sleeve 24 located at the center of the interior are in a cavity. The movable sealing plates 22 are symmetrically arranged on both sides of the cavity to connect the outer periphery of the sleeve 24 and the inner sidewall of the rotating column 11. The interval between the movable sealing plates 22 is a cavity-shaped movable drainage hole 23. The movable sealing plate 22 at one end of the rotating column 11 inserted into the rotating groove 9 protrudes outward.

[0057] In another embodiment of the present invention, the communication mechanism further includes fixed sealing plates 25 symmetrically arranged in the rotating groove 9. The cavity spacing between the fixed sealing plates 25 is a fixed drainage hole 13. An elastic sealing plate 12 is movably arranged on the end face of the fixed sealing plate 25 and the movable sealing plate 22. The elastic sealing plate 12 can be squeezed and contracted along the rotation direction of the rotating column 11 in the unfolded state of the meat rack 6.

[0058] In another embodiment of the present invention, meat placement tubes 7 are provided at intervals inside the meat placement rack 6. The meat placement rack 6 and the meat placement tubes 7 are hollow. When the meat placement tubes 7 are in a horizontal state, through holes are provided at the upper and lower end faces of the meat placement tubes 7.

[0059] Combined with appendix Figure 6 In the middle, a section of outwardly protruding movable sealing plate 22 is provided inside the rotating column 11, and movable drainage holes 23 are provided between the movable sealing plates 22; at the same time, fixed sealing plates 25 are provided in the rotating grooves 9 opened at the bottom of both sides of the folding groove 5, and fixed drainage holes 13 are provided between them; in the initial state, the meat rack 6 is folded in the folding groove 5, at this time the movable sealing plate 22 and the fixed drainage hole 13 are aligned, and the movable sealing plate 22 is used to block the fixed drainage hole 13. At the same time, the fixed sealing plate 25 and the movable drainage hole 23 are aligned, and the fixed sealing plate 25 is used to block the movable drainage hole 23, and the movable drainage hole 23 and the fixed drainage hole 13 are misaligned to prevent marinade from entering the meat rack 6 and the meat tube 7;

[0060] When the rotating column 11 rotates, the movable sealing piece 22, which protrudes outward and is correspondingly inserted into the rotating groove 9, contacts and presses the elastic sealing piece 12 provided at the end of the fixed sealing piece 25, thereby rotating and aligning the fixed drain hole 13 and the movable drain hole 23. At this time, the marinade in the marinade channel 8 can flow into the meat rack 6 and the meat tube 7 through the fixed drain hole 13 and the movable drain hole 23.

[0061] During the marinating process of meat products, the meat products are placed in layers through the meat rack 6 and the meat tube 7. At the same time, the marinade is directly discharged onto the surface of the meat products using the slots opened on the meat tube 7. While marinating the meat products in layers, each layer of meat products is in direct contact with the marinade. Even meat products that are in contact with the meat rack 6 and the meat tube 7 can directly contact the marinade. This prevents meat products at the center of the meat product stack and at the bottom of the marinating box 1 from not being able to directly contact the marinade and affecting the marinating effect.

[0062] The device also includes a folding mechanism and a connecting mechanism:

[0063] Folding Mechanism: Located on both sides inside the marinating box 1, and connected to the rotating column 11 for transmission. Its core components include a convex ring 20 fixed to the outer periphery of the rotating column 11. The outer surface of the convex ring 20 is provided with an abutment groove 21, and an abutment ball 19 is slidably abutted within the groove. The top end of the abutment ball 19 is fixedly connected to the bottom end of a top rod 16. The top rod 16 passes through a movable groove 17 in the side wall of the marinating box 1, and its top end is connected to a limiting plate 15. The limiting plate 15 slidably abuts against the lower surface of the rotating column 11 corresponding to the upper layer meat rack 6, forming a limiting lock. When the upper layer meat rack 6 is unfolded from a vertical folded state to a horizontal state (rotation angle ≤ 90°), the convex ring 20 rotates with the rotating column 11, and its arc surface, in a quarter-circle shape, pushes the abutment ball 19 downward, causing the top rod 16 and the limiting plate 15 to move downward synchronously, thereby releasing the limiting of the upper layer meat rack 6 and realizing a bottom-up layer-by-layer unlocking mechanism.

[0064] The connecting mechanism is integrated between the rotating column 11 and the rotating groove 9. The rotating column 11 has a sleeve 24 inside, forming a cavity between them. Symmetrically arranged movable sealing plates 22 are positioned within the cavity, with movable drainage holes 23 formed between adjacent movable sealing plates 22. Symmetrically arranged fixed sealing plates 25 are positioned within the rotating groove 9, forming fixed drainage holes 13 between them. An elastic sealing plate 12 is attached to the end face of the fixed sealing plate 25. In the initial folded state, the movable sealing plate 22 blocks the fixed drainage hole 13, and the fixed sealing plate 25 blocks the movable drainage hole 23, achieving a leak-proof seal. When the meat rack 6 is unfolded, the rotating column 11 rotates, causing the movable sealing plate 22 to compress the elastic sealing plate 12, aligning and connecting the movable drainage hole 23 with the fixed drainage hole 13. The marinade in the marinade tank 4 flows into the meat rack 6 and the meat placement tube 7 through this channel, and acts on the meat through the through-hole.

[0065] In addition, the top of both sides of the meat rack 6 are provided with elastic plates 10 with elastic deformation capability. When the meat racks 6 on both sides are unfolded to the horizontal position, the elastic plates 10 press against each other to form a stable connection; after use, the meat rack 6 is pulled upward, the elastic sealing plate 12 rebounds and drives the rotating column 11 to reset, the meat rack 6 automatically folds back into the folding groove 5, and the elastic plate 10 presses against the inner wall of the groove top to achieve storage and fixation.

[0066] like Figure 1 and Figure 2 As shown, the present invention provides a marinating device for meat product production, which mainly includes a marinating box 1, a feeding port 2, a cover plate 3, a marinating trough 4, a multi-layer folding trough 5, and a meat rack 6 installed therein. Before use, the cover plate 3 on the top of the marinating box 1 is opened to prepare for the loading and marinating of meat products.

[0067] like Figure 3 and Figure 4 As shown, the meat rack 6 has a frame structure, consisting of side beams on both sides and multiple hollow meat-holding tubes 7 spaced apart in the middle. The whole structure can rotate around the bottom rotating column 11 within the folding groove 5. In the initial state, all meat racks 6 are in a vertically folded state, tightly packed against the inner wall of the marinating box 1 in the corresponding folding groove 5, saving space and facilitating cleaning.

[0068] During operation, the meat rack 6 must be unfolded layer by layer from bottom to top. First, flip the bottom meat rack 6 downwards, rotating it from a vertical position to a horizontal position (rotation angle ≤ 90°). During this process (see...), Figure 5 – Figure 8The rotating column 11, fixed to the bottom of the meat rack 6, rotates synchronously. The rotating column 11 has a raised ring 20 on its outer circumference, with an abutment groove 21 on its surface, into which an abutment ball 19 is embedded. As the raised ring 20 rotates along the rotating track 18, its arc surface gradually pushes the abutment ball 19 downwards, causing the connected push rod 16 to slide vertically down along the movable groove 17. The limiting plate 15 connected to the top of the push rod 16 then descends, disengaging from the pressing limit on the lower surface of the corresponding rotating column 11 of the upper meat rack 6, thereby unlocking the upper meat rack 6 and allowing it to be unfolded. This design ensures that operation can only be performed sequentially from bottom to top, avoiding accidental opening of the upper layer, which could lead to structural instability or operational confusion.

[0069] When the meat rack 6 is fully extended to a horizontal position (as shown in the image) Figure 3 As shown in the diagram, the elastic plates 10 at the top of both sides of the meat rack 6 contact each other and generate elastic compression, forming a stable lateral support to prevent the meat rack 6 from shaking or rebounding when placing meat. At this time, the meat pieces to be marinated can be placed on the meat placement tube 7. Since the meat placement tube 7 is hollow inside and has through holes on the upper and lower end faces, the channel will not be completely closed after the meat is placed.

[0070] At the same time, the connecting mechanism starts automatically, such as Figure 6 As shown, the rotating column 11 has a sleeve 24 inside, forming an annular cavity between them. Movable sealing plates 22 are symmetrically arranged within the cavity, and movable drainage holes 23 are formed between adjacent movable sealing plates 22. The rotating groove 9 has a fixed sealing plate 25 and a fixed drainage hole 13, with an elastic sealing plate 12 attached to its end face. In the folded state, the movable sealing plate 22 blocks the fixed drainage hole 13, and the fixed sealing plate 25 blocks the movable drainage hole 23, achieving a complete seal and preventing marinade leakage. When the rotating column 11 rotates to the unfolded position with the meat rack 6, the outwardly protruding end of the movable sealing plate 22 presses against the elastic sealing plate 12, causing it to elastically deform and contract, thus precisely aligning and connecting the movable drainage hole 23 with the fixed drainage hole 13. At this time, the liquid marinade injected through the feeding port 2 flows into the marinade tank 4, enters the marinade channel 8 through the connected drainage hole, and is finally evenly sprayed onto the surface of the meat through the through holes on the upper and lower ends of the meat placement tube 7, achieving efficient and three-dimensional marinating.

[0071] After all meat racks 6 have been unfolded and the meat loaded, close the cover 3 and let it marinate. Once marinated, remove the meat and lift any meat rack 6 upwards to release the pressure between the elastic plates 10. At this time, the elastic sealing plate 12 rebounds due to its own elasticity, pushing the rotating column 11 to rotate in the opposite direction, causing the meat rack 6 to automatically return to its vertically folded state and reposition and seal the drainage holes to prevent residual marinade from leaking out. At the same time, after the elastic plate 10 is folded into place, it presses against the inner wall of the top of the folding groove 5, providing a certain frictional resistance to ensure that the meat rack 6 remains stably folded during transportation or storage.

[0072] In summary, this invention, through the ingenious combination of mechanical linkage, sealing control, and layered structure, achieves automation, uniformity, and high efficiency in the meat product marinating process, which is significantly superior to traditional stacked marinating methods.

[0073] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
