Description

Technical Field

[0001] This utility model relates to the technical field of liquid food filling production lines, and in particular to a quick-release can support device for easy-open cans. Background Technology

[0002] In the beverage and alcohol bottling industry, contract manufacturers need to provide bottling services for multiple well-known brands, and the size and shape of the cans vary significantly among these brands. To accommodate the production needs of different can types, can handling platforms must be equipped with matching can support devices to secure the cans.

[0003] Traditional tank protectors are typically fixed to the positioning column assembly on the tank carrier using bolts or clips, making disassembly and assembly highly dependent on external tools such as wrenches. When the production line changes tank types, operators must disassemble and reinstall multiple tank protectors one by one, a process that is not only cumbersome but also time-consuming. Especially in scenarios with a large number of tank protectors, frequent tool operations significantly increase changeover time, causing prolonged production line downtime and severely impacting equipment operating efficiency and production capacity.

[0004] Meanwhile, tool dependence increases operational complexity, making it prone to installation errors or human mistakes, further exacerbating the risk of production interruptions. In existing technologies, the fixing structure of the can holder lacks a convenient and quick disassembly and assembly mechanism, making it impossible to achieve immediate replacement without tools, and thus failing to meet the urgent needs of modern filling production lines for efficient and flexible changeover.

[0005] In summary, the existing fixed connection method between the tank support and the tank carrier has problems such as cumbersome disassembly and assembly, low disassembly and assembly efficiency, which leads to reduced equipment operating efficiency and production capacity.

Its main function is to achieve stable clamping of the can through the combination of multiple can holders. Specifically, the can holder can be made of metal or high-strength plastic to meet the needs of different usage scenarios.

[0009] The positioning sleeve is a key component used to quickly connect the tank protector and the positioning post assembly.

As a preferred embodiment, the positioning sleeve can be fixed to the lower tank protector plate via threaded connections, snap-fit ​​connections, or other methods, not limited to fixing with mounting parts. Furthermore, the assembly cavity can be designed in a polygonal or elliptical shape to provide higher positioning accuracy in specific scenarios.

[0010] This quick-release can holder device for beverage cans achieves rapid fixing and disassembly through the cooperation of the positioning sleeve and the snap ring, without the need for external tools.

[0013] Furthermore, the arc segment A is circular, and the central angle of the arc segment A is not less than 180°.

[0014] Furthermore, the connection between the straight segment B and the arc segment B is a circular arc transition.

[0015] Furthermore, the circular structure formed by several tank supports has an axis A, and the tank platform has an axis B, with axis A and axis B being collinear.

[0028] like Figures 1 to 6 As shown in the figure, the present invention provides a quick-release can holder device for easy-open cans, which is disposed on a can support platform 10. The can support platform 10 is provided with several sets of positioning post groups, each of which includes several positioning posts 9. Specifically, the quick-release can holder device for easy-open cans includes several can holders 100, which are arranged in a circular structure, and the several can holders 100 are respectively disposed on several sets of positioning post groups. The tank support 100 includes a lower tank support plate 1 and an upper tank support plate 2 that are parallel to each other and spaced apart. The lower tank support plate 1 and the upper tank support plate 2 are connected by a number of connectors 200. A positioning sleeve 4 is provided on the side of the lower protective tank plate 1 away from the upper protective tank plate 2. An assembly cavity 401 that cooperates with the positioning post 9 is provided in the positioning sleeve 4. A retaining spring 3 is provided on the positioning sleeve 4. The positioning sleeve 4 and the positioning post 9 are fixed together by the retaining spring 3. The can holder 100 can be understood as a structural unit used to protect and secure aluminum cans. Its main function is to achieve stable clamping of the aluminum can through the combination of multiple can holders 100. Specifically, the can holder 100 can be made of metal or high-strength plastic to meet the needs of different usage scenarios.

[0029] The positioning sleeve 4 is a key component for quickly connecting the tank protector 100 and the positioning post assembly. Its internal assembly cavity 401 matches the outer diameter of the positioning post 9, ensuring precise alignment. In a preferred embodiment, the positioning sleeve 4 can be fixed to the lower tank protector 1 via threaded connection, snap-fit ​​connection, or other methods, not limited to fixing with mounting parts. Furthermore, the assembly cavity 401 can be designed in a polygonal or elliptical shape to provide higher positioning accuracy in specific scenarios.

[0030] The main function of the retaining ring 3 is to achieve quick fixing and disassembly between the positioning sleeve 4 and the positioning post 9 through its elastic deformation. Specifically, the retaining ring 3 can be inserted into the positioning post 9 by rotation, thereby locking the two together.

[0031] The innovation of this application lies in the cooperation mechanism between the retaining ring 3, the positioning sleeve 4, and the positioning post 9, which enables the rapid assembly and disassembly of the tank protector 100 without tools. Compared with the traditional method that relies on tools such as wrenches for assembly and disassembly, this design significantly shortens changeover time and reduces labor intensity. At the same time, the modular design of the tank protector 100 allows it to flexibly adapt to the needs of different tank types, thereby improving the overall efficiency of the production line.

[0032] The working principle of this embodiment is as follows: The device sets several sets of positioning posts on the can support platform 10 and installs several can holders 100 on the positioning posts to form an enclosed circular structure, thereby providing stable support and protection for the cans. Each can holder 100 consists of a lower can holder plate 1 and an upper can holder plate 2, which are fixed in parallel by a connector 200 to ensure the stable placement of the cans. Further, a positioning sleeve 4 is provided on the side of the lower can holder plate 1 away from the upper can holder plate 2. The positioning sleeve 4 has an assembly cavity 401 that cooperates with the positioning post 9. Through the precise alignment design of the assembly cavity 401 and the positioning post 9, the can holder 100 can be quickly positioned and installed. Specifically, the positioning sleeve 4 is provided with a retaining spring 3. After the positioning sleeve 4 and the positioning post 9 are assembled, the retaining spring 3 is rotated to assemble with the positioning post 9, thereby fixing the can holder 100. Thus, the installation and removal of the can holder 100 can be completed without the need for tools such as wrenches. When a can type needs to be changed, simply rotate the retaining ring 3 in the reverse direction to disengage it from the positioning post 9, allowing for quick removal of the can holder 100. This design, based on the cooperation of the retaining ring 3 with the positioning sleeve 4 and the positioning post 9, significantly simplifies the assembly and disassembly process, effectively solving the problems of long changeover times and low production efficiency caused by the reliance on tools in traditional can holders. Furthermore, the independent operation of each can holder 100 avoids impacting other components, further improving changeover efficiency.

[0033] like Figures 1 to 7 As shown, in some embodiments of this utility model, there are no fewer than two positioning sleeves 4 on each lower protective tank plate 1, and the number of positioning pins 9 in each group of positioning pins corresponding to each protective tank seat 100 is the same as the number of positioning sleeves 4. This corresponding number design ensures the stability and balance of the can holder 100 during installation, preventing tilting or shaking caused by single-point positioning. Simultaneously, the cooperation of multiple positioning sleeves 4 and multiple positioning posts 9 disperses the forces during installation, reducing stress concentration on individual components and thus extending the service life of the can holder 100. In practical applications, this design also allows the can holder 100 to adapt to cans of different sizes and shapes, improving the versatility and flexibility of the device.

[0034] like Figures 1 to 7 As shown, in some embodiments of this utility model, the positioning sleeve 4 has an annular snap ring assembly groove 402 on its outside, and the annular snap ring assembly groove 402 has an assembly notch A 403 that communicates with the assembly cavity 401. The positioning post 9 has an assembly notch B 901 that mates with the retaining ring 3; the assembly notch B 901 is annular. Specifically, the annular snap ring assembly groove 402 refers to a groove structure formed around the outer wall of the positioning sleeve 4, which can be achieved by machining methods such as milling or turning, to provide a precise installation position and guide path for the snap ring 3. The assembly notch A 403 can be understood as an opening structure extending from the annular snap ring assembly groove 402 to the assembly cavity 401, which can be formed by machining, to provide a convenient passage for the installation of the snap ring 3. In practical applications, the assembly notch B 901 refers to a groove structure opened at a specific position on the positioning post 9, which can be formed by machining, to form a mating relationship with the snap ring 3 to achieve a fixing function.

[0035] In detail, this technical solution provides a stable mounting base for the snap ring 3 through the annular snap ring mounting groove 402, preventing the snap ring 3 from shifting during operation. The design of the mounting notch A 403 allows the snap ring 3 to easily slide into the annular snap ring mounting groove 402, simplifying the installation process. After the positioning sleeve 4 and the positioning post 9 are assembled, the snap ring 3 can be reliably fixed by rotating into the mounting notch B 901. This design fully utilizes the elastic deformation characteristics of the snap ring 3, eliminating the need for additional tools during the assembly and disassembly of the can holder, significantly improving operational efficiency. Overall, these features together construct a complete snap ring guiding, positioning, and locking system, transforming the traditionally cumbersome process that relies on tools into an intuitive rotational action, fundamentally shortening the replacement time of the can holder and effectively solving the problem of snap rings easily shifting or falling off during installation.

[0036] like Figures 1 to 7 As shown, in some embodiments of this utility model, the snap ring 3 includes an arc segment A 302 and straight segments A 301 and B 303 disposed at both ends of the arc segment A 302. An arc segment B 304 is also provided at the end of the straight segment B 303 away from the arc segment A 302. The arc-shaped segment B 304 is arc-shaped and mates with the annular snap ring assembly groove 402; in addition, the shape of the arc-shaped segment B 304 also mates with the assembly notch B 901. Specifically, the arc-shaped segment A 302 refers to the elastic main body of the retaining ring 3, which can be made of a metal material with a certain degree of toughness and resilience. Its purpose is to provide the retaining ring 3 with the necessary elastic deformation capacity to adapt to stress changes during installation and disassembly. The straight segment A 301 can be understood as a structure used to guide the retaining ring 3 to maintain a linear trajectory during rotation. Its straightness can be ensured through precise machining, thereby avoiding jamming. The straight segment B 303 is used to connect to the arc-shaped segment B 304. The arc-shaped segment B 304 is designed to achieve automatic assembly of the retaining ring 3 within the annular retaining ring assembly groove 402. Its curvature can be adjusted to match the contour of the assembly groove, thereby reducing frictional resistance and enhancing fixing reliability.

[0037] In detail, the above technical solution significantly improves the stability and convenience of quick-release operation by optimizing the geometry of the retaining ring 3. The arc-shaped segment A 302, acting as an elastic body, can deform appropriately according to the groove shape of the positioning post 9 during installation or disassembly, while maintaining sufficient elastic restoring force. The straight segments A 301 and B 303 provide clear guidance during rotation, ensuring that the retaining ring 3 moves smoothly along a predetermined path, avoiding operational difficulties caused by misalignment. In particular, the design of the arc-shaped segment B 304 in conjunction with the annular retaining ring assembly groove 402 not only reduces frictional resistance during rotation but also enhances the fixing effect of the retaining ring 3 within the groove, making the insertion and disengagement actions smoother. Furthermore, this solution, together with the annular retaining ring assembly groove 402 of the positioning sleeve 4 and the assembly notch B 901 of the positioning post 9, forms a close functional relationship, jointly achieving efficient and reliable assembly and disassembly of the can-protecting device, meeting the actual needs of rapid changeover on the production line.

[0038] like Figures 1 to 7 As shown, in some embodiments of this utility model, the arc segment A 302 is circular arc-shaped, and the central angle of the arc segment A 302 is not less than 180°; Specifically, the arc segment A 302 can be made of a metallic elastic material with a regular curvature, such as spring steel or stainless steel, and formed into the required arc shape through a stamping process. The purpose is to utilize its elastic properties to ensure that the arc segment B 304 on the retaining ring 3 can form a stable and continuous contact surface with the groove (i.e., assembly notch B 901) of the positioning post 9 during rotation, thereby improving the fixing reliability and avoiding jamming caused by local stress concentration.

[0039] In detail, this technical solution significantly improves the performance of the retaining ring 3 during fixing and disassembly by defining the specific geometric characteristics of the arc segment A 302. The arc segment A 302 adopts an arc-shaped design, which effectively avoids local stress concentration or jamming problems caused by irregular shape, thereby ensuring smooth operation and durability. At the same time, setting the central angle of the arc segment A 302 to be no less than 180° ensures that the arc segment B 304 on the retaining ring 3 covers a semi-circle or larger area when embedded in the groove of the positioning post 9 (i.e., the assembly notch B901). This not only enhances the gripping force between the retaining ring 3 and the groove, but also prevents loosening caused by vibration or external forces during equipment operation.

[0040] like Figures 1 to 7 As shown, in some embodiments of this utility model, the connection between the straight segment B 303 and the arc segment B 304 is a circular arc transition. Specifically, the straight segment B 303 refers to the straight edge structure of the snap ring 3 located at the end of the arc segment A 302 and extending to the arc segment B 304. It can be made of a metal material with a certain degree of rigidity and elasticity, and its purpose is to provide stable support and guidance for the snap ring 3. The arc segment B 304 refers to the part of the snap ring 3 used to embed into the groove of the positioning post 9 (i.e., the assembly notch B 901). It can adopt an arc-shaped design to achieve a smooth transition, and its purpose is to reduce stress concentration and improve the durability of the snap ring 3. The arc-shaped transition refers to the use of an arc shape to connect the straight segment B 303 and the arc segment B 304. It can be achieved through machining or forming processes, and its purpose is to disperse local stress and enhance structural strength.

[0041] Specifically, the above technical solution effectively solves the stress concentration problem by designing the connection between the straight segment B 303 and the arc segment B 304 as a circular arc transition. In actual operation, when the retaining ring 3 needs to be repeatedly rotated for installation or removal, the circular arc transition ensures a more uniform stress distribution, avoiding localized high-stress points caused by right-angle connections. This design is particularly suitable for quick-release can support devices that require frequent installation and removal, ensuring the stability and reliability of the retaining ring 3 during long-term use. Simultaneously, this design, in conjunction with the positioning sleeve 4, the assembly cavity 401, and the assembly notch B 901, collectively enhances the service life and ease of operation of the entire can support device.

[0042] The above technical solution not only solves the problem of cracks or breakage of the snap ring 3 during repeated operation, but also significantly improves the overall performance of the quick-release tank support device, thereby meeting the requirements for equipment changeover time in actual production.

[0043] like Figures 1 to 7As shown, in some embodiments of this utility model, a circular structure formed by several tank protectors 100 has an axis A, and the tank platform 10 has an axis B, with axis A and axis B being collinear. Specifically, axis A refers to the geometric center axis of the circular structure formed by several tank protectors 100. It can be determined by the distribution of the tank protectors 100, aiming to provide a precise positioning reference for the entire device. In practical applications, axis A can be precisely positioned using laser alignment technology or mechanical calibration. Axis B refers to the central axis of the tank carrier 10, which can be ensured by the machining accuracy and assembly process of the tank carrier 10, aiming to ensure the stability of the conveying path. The collinear design of axes A and B forces the axis of the tank protector device to be geometrically perfectly aligned with the axis of the tank carrier, thereby eliminating radial offset caused by axial deviation.

[0044] In detail, this solution fundamentally solves the alignment problem of cans during transportation through a collinear design. First, the circular structure formed by the can protector 100 clearly defines the geometric center axis of the entire device, avoiding structural eccentricity caused by uneven distribution of the can protectors. Second, the axis of the can-carrying platform 10 serves as a fixed reference for system operation, ensuring the stability of the transportation path. When axis A and axis B are collinear, it ensures that the installation shape of the can protector 100 matches the top installation area of ​​the can-carrying platform 10. Furthermore, this design improves the continuous operation capability of the production line and the efficiency of rapid debugging after model changeovers. Its advantages in improving production efficiency are particularly evident when combined with the quick-release structure of the positioning sleeve 4 and positioning column 9.

[0045] like Figures 1 to 7 As shown, in some embodiments of this utility model, the connecting member is composed of countersunk screws 7, nuts 8 and columns 5, with the columns 5 located between the lower protective tank plate 1 and the upper protective tank plate 2. The countersunk screw 7 passes through the upper protective tank plate 2, the column 5 and the lower protective tank plate 1 in sequence, and is locked by the nut 8; Specifically, column 5 refers to a spacer structure used to maintain a fixed distance between the upper and lower can guard plates. It can be implemented using a metal cylinder, a high-strength plastic column, or other components with rigid support characteristics. Its purpose is to ensure that the lower can guard plate 1 and the upper can guard plate 2 maintain a parallel and constant distance after assembly. Countersunk screw 7 refers to a fastener whose head can be fully embedded in the contact surface. It can be implemented using standard countersunk screws or customized countersunk screws. Its purpose is to eliminate any physical interference that the screw head may cause to the can, while ensuring the overall continuity of the connection. Nut 8 refers to a fastener used in conjunction with the screw. It can be implemented using a hexagonal nut, a lock nut, or other nut types with anti-loosening function. Its purpose is to provide adjustable tightening force control, thereby avoiding connection loosening problems caused by equipment vibration.

[0046] Specifically, in the above scheme, the column 5, as the core partition structure, is precisely positioned between the lower can cover 1 and the upper can cover 2 to ensure that they maintain a constant distance and parallel posture, thereby avoiding geometric deformation of the accommodating space due to gap fluctuations. The countersunk screw 7 passes sequentially through the upper can cover 2, the column 5, and the lower can cover 1. This path design allows the connection force to be evenly transmitted to all components, while the countersunk design eliminates the risk of protruding screw heads, preventing physical interference with the can. The countersunk screw 7 is locked with a nut 8, achieving adjustable tightening force control and ensuring the connection remains stable during equipment vibration, avoiding can cover failure caused by loosening. Furthermore, the above connection method, combined with a standardized structural design, effectively solves the problems of loose connections or uneven surfaces that may occur during assembly, thereby improving the reliability and operational consistency of the can cover under dynamic operating conditions.

[0047] The above technical solutions not only solve the technical problem of maintaining a precise parallel relationship and fixed distance between the upper and lower can guards, but also significantly improve the positioning accuracy and can guard stability of the cans, providing strong support for efficient changeover on the production line.

[0048] like Figures 1 to 7 As shown, in some embodiments of this utility model, a washer 6 is sleeved on the outside of the countersunk screw 7, and the washer 6 is located between the head of the countersunk screw 7 and the upper protective plate 2. Specifically, washer 6 refers to a ring-shaped component with buffering and pressure-dispersing functions. It can be made of metal, rubber, or composite materials, and its specific forms include flat washers and spring washers. Its purpose is to provide a flexible contact surface, preventing the head of the countersunk screw 7 from directly acting on the surface of the upper protective plate 2, thereby reducing localized stress concentration. Furthermore, washer 6 is positioned at a specific location between the head of the countersunk screw 7 and the upper protective plate 2, fully utilizing the contour characteristics of the countersunk screw 7 head to ensure that the tightening force is evenly distributed throughout the contact area.

[0049] In detail, this solution effectively solves the problem of surface damage to the upper tank plate 2 caused by repeated disassembly and assembly by installing a washer 6 outside the countersunk screw 7. The washer 6 acts as a buffer layer, preventing direct hard contact between the metal surface of the countersunk screw 7 head and the upper tank plate 2, thus preventing surface scratches or deformation caused by localized stress concentration from repeated tightening. Simultaneously, the presence of the washer 6 ensures that the connection point maintains a tight fit after multiple disassembly and assembly, preventing loosening and supporting a quick and non-destructive disassembly and installation process. Based on this, combined with the overall structural design of the tank support 100, the stability and quick-disassembly performance of the device during frequent changeover operations are further improved, meeting the needs of efficient changeover on the production line.

[0050] The above technical solution not only protects the integrity of the surface of the upper tank plate 2, but also significantly improves the service life and reliability of the tank support device, providing a strong guarantee for the efficient operation of the production line.

[0051] like Figures 1 to 7 As shown, in some embodiments of this utility model, the outer circumferential surface of the lower protective tank plate 1 is evenly distributed with accommodating grooves A 101; A receiving groove B 201 is provided on the upper protective plate 2 at the position corresponding to the receiving groove A 101, and a receiving space for accommodating the can is formed between the receiving groove A 101 and the receiving groove B 201; Specifically, the accommodating groove A 101 refers to multiple groove structures evenly distributed on the outer circumferential surface of the lower can guard plate 1. These grooves can be achieved through machining methods such as milling or stamping, and their purpose is to provide evenly distributed positioning points for the bottom of the can, restricting its radial movement. The accommodating groove B 201 refers to a groove structure corresponding to and matching the shape of the accommodating groove A 101. This groove can be achieved through CNC machining or mold forming processes, and its purpose is to cooperate with the accommodating groove A 101 to form an upper and lower clamping effect, constraining the axial displacement of the can. The accommodating space refers to the specific area enclosed by the accommodating grooves A 101 and B 201. The precise design of the dimensions and positional relationship of the two grooves adapts to different can types, thereby achieving rapid form changeover.

[0052] In detail, the receiving groove A 101 on the lower can protector plate 1 is designed based on the contour features of the bottom of the can, ensuring that the can will not wobble horizontally after being inserted. The receiving groove B 201 on the upper can protector plate 2 is optimized for the upper shape of the can, forming a clamping effect with the receiving groove A 101, thereby fixing the can in the vertical direction. When the two work together, they can not only stably accommodate the can, but also quickly adapt to the new shape and size when changing can types by adjusting the can protector assembly. In addition, this solution, combined with the overall structure of the aforementioned can protector device, allows the quick-release function to be fully utilized, significantly improving the operating efficiency and stability of the production line.

[0053] The above technical solution solves the problem of cans shaking and falling off the can-carrying platform due to the lack of a dedicated positioning structure, while achieving the goal of rapid changeover, reducing labor intensity and improving production efficiency.

[0054] like Figures 1 to 7 As shown, in some embodiments of this utility model, the positioning sleeve 4 is externally fitted with an installation part 404, and the installation part 404 is fixed to the lower protective tank plate 1 by bolt connection. Specifically, mounting component 404 refers to a transitional structure used to achieve a detachable connection between the positioning sleeve 4 and the lower protective tank plate 1. It can be implemented using an annular sleeve made of metal or high-strength plastic. The purpose is to transform the connection between the positioning sleeve 4 and the lower protective tank plate 1 into a modular interface through this independent intermediate component. The bolted connection method can be understood as a mechanical connection form that uses threaded fasteners to achieve quick assembly and disassembly. It can be implemented using hexagonal bolts with nuts or directly using mounting component 404 with threaded holes, aiming to simplify the replacement operation of the positioning sleeve 4 and improve maintenance efficiency.

[0055] In detail, this solution uses an mounting component 404 as a transition structure on the outside of the positioning sleeve 4. This allows the positioning sleeve 4 to no longer be directly fixed to the lower tank protector plate 1, but instead forms a modular interface that can be independently disassembled and installed through the mounting component 404. When the positioning sleeve 4 becomes worn or damaged, the operator only needs to loosen the bolts fixing the mounting component 404 to remove the positioning sleeve 4 together for replacement, without requiring any modifications to the lower tank protector plate 1. Furthermore, since the mounting component 404 is fixed by bolts, this design not only ensures the reliability of the connection but also significantly reduces maintenance difficulty. Combined with the overall structure of the aforementioned tank protector 100, this detachable design is particularly suitable for production scenarios that require frequent replacement of different specifications of tank protector 100, effectively shortening the changeover time of the production line and improving the convenience of equipment maintenance.

[0056] like Figure 8 As shown, this is the assembly process of the can holder 100 and the positioning post assembly in another embodiment of the present invention, which is divided into an installation step and a disassembly step: In the installation step, the positioning sleeve 4 is fitted onto the outside of the positioning post 9, and the retaining spring 3 is rotated so that the position of the retaining spring 3 is from Figure 8 From the open position to the close position, the arc segment B 304 on the retaining spring 3 rotates into the assembly notch A 403 of the positioning sleeve 4. At the same time, since the positioning sleeve 4 is fitted outside the positioning post 9, under the elastic action of the arc segment A 302, the arc segment B 304 on the retaining spring 3 can closely adhere to the positioning post 9 through the assembly notch A 403 and be embedded in the assembly notch B 901 on the positioning post 9. After assembly, the arc segment B 304 of the retaining spring 3 is partially located in the assembly notch B 901 on the positioning post 9 and the other part is located in the assembly notch A 403 on the positioning sleeve 4, thereby realizing the assembly and fixation of the positioning sleeve 4 and the positioning post 9.

[0057] During the disassembly process, based on the installation steps described above, it is only necessary to rotate the retaining ring 3 in the reverse direction to change its position from... Figure 8From the close position to the open position, the retaining spring 3 disengages from the assembly notch B 901 on the positioning post 9. Then, the positioning sleeve 4 is lifted up to disengage from the positioning post 9, thus completing the removal of the positioning sleeve 4 from the positioning post 9 and the removal of the tank protector 100 from the outside of the positioning post assembly.

[0058] Although the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
