Description

Technical Field

[0001] This invention belongs to the technical field of aeration liquid extraction, and specifically relates to a liquid storage device, a liquid storage method, and a liquid extraction method. Background Technology

[0002] In modern life, there are increasingly higher requirements for the storage and use of liquids. Traditional liquid storage devices often have many shortcomings. For example, during storage, liquids are easily exposed to air, leading to oxidation and evaporation, which affects the quality and performance of the liquid. This is especially true for liquids that have high requirements for storage conditions, such as wine, where oxidation and evaporation upon contact with air can easily affect their taste.

[0003] Furthermore, traditional liquid storage devices have a relatively simple structural design and limited functionality. The storage and retrieval processes may require complex operating procedures, and due to the limited application scenarios of the structure, there are problems such as the inability to retrieve stored liquids as needed and the inability to reuse the device. Summary of the Invention

[0004] In order to solve the above-mentioned problems in the prior art, this application provides a liquid storage device, a liquid storage method, and a liquid extraction method to solve the above-mentioned technical defects.

[0005] According to a first aspect of the present invention, a liquid storage device is provided, characterized in that it includes a liquid storage body, a liquid dispensing component, and an air injection component. The liquid dispensing component and the air injection component are respectively disposed at both ends of the liquid storage body. The liquid storage body is hollow inside and is provided with a gas-liquid isolation piston. The gas-liquid isolation piston separates the interior of the liquid storage body into a liquid storage cavity and an air filling cavity. When the air injection component injects air into the air filling cavity, it can push the gas-liquid isolation piston to compress the liquid storage cavity, causing the internal liquid to flow out from the liquid dispensing component. The liquid dispensing component and the air injection component are configured in the same way as the liquid storage body and are interchangeable. This liquid storage device, through the combination of the liquid storage body, the liquid dispensing component, and the air injection component, and the setting of the internal gas-liquid isolation piston, realizes the function of injecting air into the air filling cavity to push the gas-liquid isolation piston and cause the liquid to flow out from the liquid dispensing component. At the same time, the liquid dispensing component and the air injection component are configured in the same way and are interchangeable, which increases the flexibility and convenience of use, and ensures that the liquid retrieval process after storage initialization does not come into contact with air, avoiding liquid oxidation and evaporation.

[0006] In some specific embodiments, the liquid storage body is a hollow cylindrical structure, and the liquid outlet component and the gas injection component are sealed and fixed to the open ends of the hollow cylindrical structure by means of threads or snaps. The liquid outlet component and the gas injection component are sealed and fixed to the two ends of the hollow cylindrical structure by means of threads or snaps, which facilitates installation and disassembly and improves the reliability and maintainability of the device.

[0007] In some specific embodiments, the liquid storage body has a double-layer structure. This double-layer structure serves two purposes: firstly, it better protects the internal cavity, preventing external impacts from causing the gas-liquid isolation piston to jam and the medium in the storage compartment to leak; secondly, the interlayer provides insulation, making it suitable for storing temperature-sensitive liquids.

[0008] In some specific embodiments, the gas-liquid isolation piston includes a piston body and a sealing ring. The piston body is a circular disc with a diameter smaller than the inner diameter of the liquid storage body, and the outer edge of the disc is fitted with a sealing ring that seals against the inner wall of the liquid storage body. The design of the piston body and sealing ring of the gas-liquid isolation piston ensures a good seal between the piston and the inner wall of the liquid storage body, preventing leakage of liquid and gas between the liquid storage cavity and the gas filling cavity, thus ensuring the normal operation of the device.

[0009] In some specific embodiments, the gas-liquid isolation piston further includes a bidirectional on / off valve disposed in the middle of the disc. The bidirectional on / off valve includes a valve core, a sealing plate, and a reset elastic body. The sealing plate has a through hole in its middle, through which the valve core passes and is sealed to the through hole. A pair of reset elastic bodies are symmetrically disposed at both ends of the valve core. The bidirectional on / off valve is activated when either end of the valve core triggers the liquid dispensing assembly. When liquid dispensing is nearly complete, the bidirectional on / off valve in the middle of the gas-liquid isolation piston is activated, causing gas from the pressure chamber side to rush into the liquid storage chamber. This allows for complete removal of the remaining liquid even when the liquid dispensing port is at a low position, improving liquid utilization. Furthermore, after liquid dispensing is completed, opening the liquid dispensing end cap restores the sealing state under the action of the reset elastic body, facilitating gas-liquid chamber switching.

[0010] In some specific embodiments, the liquid dispensing assembly includes a switch structure, a dispensing head, a dispensing body, and a dispensing valve core structure. The dispensing body has a dispensing cavity in its center for accommodating the dispensing valve core structure, and a protruding connecting portion is formed in the center of its outer surface. The dispensing head is fitted onto the protruding connecting portion of the dispensing body. The switch structure is located on the dispensing head. When the switch structure is activated, it triggers the dispensing valve core structure to control the connection or closure of the dispensing cavity and the dispensing head. The design of the switch structure, dispensing head, dispensing body, and dispensing valve core structure of the liquid dispensing assembly makes the liquid dispensing control more precise and reliable, allowing the dispensing port to be opened or closed as needed, facilitating liquid dispensing.

[0011] In some specific embodiments, the dispensing valve core structure includes a valve core fixing seat, a dispensing valve core, a bushing, a return spring, and a sealing sleeve. The valve core fixing seat is fixedly disposed on the lower end face of the dispensing cavity. Multiple channels connecting the dispensing cavity and the storage cavity are perforated on the surface of the valve core fixing seat. The dispensing valve core is fixedly disposed in the middle of the valve core fixing seat. The bushing has a valve core cavity for accommodating the dispensing valve core. The return spring is disposed between the dispensing valve core and the valve core cavity. The sealing sleeve covers the connection between the dispensing valve core and the bushing. The cooperation of the valve core fixing seat, dispensing valve core, bushing, return spring, and sealing sleeve in the dispensing valve core structure ensures stable operation and good sealing of the dispensing valve core, reduces the accumulation of impurities, improves the quality of the dispensing liquid, and extends the service life of the device.

[0012] In some specific embodiments, a filter screen is detachably mounted on the bottom of the liquid dispensing assembly, and one end of the liquid dispensing valve core extends out from the bottom of the valve core mounting base. The filter screen is detachably fitted to one end of the liquid dispensing valve core. The detachable filter screen at the bottom of the liquid dispensing assembly can filter impurities in the liquid, ensuring the purity of the flowing liquid. The detachable design also facilitates cleaning and replacement of the filter screen.

[0013] In some specific embodiments, the air injection component is a self-supplying structure, which includes a manual air injection device and a one-way check valve. The manual air injection device includes an air bladder or bellows, and a one-way check valve is installed between the manual air injection device and the inflation chamber. This design facilitates air injection operations without external air supply equipment, improving the applicability and portability of the device.

[0014] In some specific embodiments, the manual air injection device is equipped with an air intake check valve, which includes a valve plate and valve ports at the upper and lower ends of the valve plate. The valve port leading to the air bladder end is configured with a quincunx opening. The quincunx opening configuration of the air intake check valve on the manual air injection device improves the efficiency and stability of air intake, prevents gas backflow, and ensures the effectiveness of manual air injection.

[0015] In some specific embodiments, the gas injection component is an external gas supply structure, which includes a direct gas supply structure or a gas storage structure. The direct gas supply structure includes a one-way inlet and a pressure relief valve, with the one-way inlet connected to an external inflation device. The gas storage structure also includes a sealed chamber, which is equipped with a pressure reducing valve and a check valve. After the external inflation device injects gas, it sequentially passes through the pressure reducing valve and the check valve into the inflation chamber to reach a preset pressure. Further pressurization and storage in the sealed chamber allows for a continuous and stable gas supply to the inflation chamber without external piping. The external gas supply structure of the gas injection component, including either a direct gas supply structure or a gas storage structure, meets the gas supply needs of different application scenarios. The direct gas supply structure is simple and convenient, suitable for situations with external inflation devices; the gas storage structure can continuously and stably supply gas to the inflation chamber without external piping, increasing application scenarios and improving the reliability of the device.

[0016] According to a second aspect of the present invention, a liquid storage method is provided, utilizing the liquid storage device as described above, comprising:

[0017] S1: Inject the liquid to be stored into the interior of the liquid storage body, and assemble the liquid outlet component and the gas injection component;

[0018] S2: Turn on the switch of the liquid outlet component, and inject air from the bottom air injection component in the vertical position;

[0019] S3: When the liquid to be stored flows out from the outlet of the liquid outlet component, close the switch to isolate the liquid storage chamber from the outside and complete the liquid storage operation.

[0020] According to a third aspect of the present invention, a liquid extraction method is provided, comprising the liquid storage method as described above, and further comprising:

[0021] S4: Turn on the switch of the liquid outlet assembly, and use the air injection assembly to inject air to push the gas-liquid isolation piston to force the liquid out of the storage chamber;

[0022] S5: After the liquid in the storage chamber is completely removed, the liquid outlet component and the gas injection component are removed and cleaned. Then, the installation positions of the liquid outlet component and the gas injection component are adjusted, and S1-S4 are repeated to perform the liquid storage and liquid retrieval operations.

[0023] Compared with the prior art, the beneficial results of the present invention are as follows:

[0024] 1. To prevent liquid oxidation and evaporation, the gas-liquid isolation piston divides the inside of the liquid storage body into a liquid storage chamber and an air filling chamber, so that the liquid does not come into contact with air during storage and retrieval, thus minimizing the oxidation and evaporation of the stored liquid and ensuring the quality and performance of the liquid.

[0025] II. Flexible structural design: The liquid outlet and gas injection components are interchangeable with the liquid storage body, increasing usability. The position of the gas-liquid chamber can be adjusted according to actual needs, facilitating use while reducing damage to the piston sealing ring from frequent disassembly and assembly. The liquid storage body adopts a double-layer structure, which not only better protects the inner cavity, preventing piston jamming and leakage of the chamber medium due to external impacts, but also provides insulation to meet the storage temperature requirements of different liquids.

[0026] Third, precise liquid discharge control and filtration functions: The design of the liquid discharge component's switching structure and the liquid discharge valve core structure makes liquid discharge control more precise and reliable, allowing the liquid outlet to be opened or closed at any time. The removable filter screen at the bottom of the liquid outlet can filter impurities in the liquid, ensuring the purity of the flowing liquid and preventing foreign objects from causing the internal valve structure to fail to seal.

[0027] IV. Diverse gas injection methods: The gas injection components are divided into self-supply and external gas supply structures. The self-supply structure includes a manual gas injection device, facilitating gas injection operations when no external gas supply equipment is available, thus improving the device's applicability and portability. The external gas supply structure is further divided into direct gas supply and gas storage structures, meeting the gas supply needs of different usage scenarios and expanding the application scenarios.

[0028] V. High efficiency in liquid extraction and utilization: When liquid extraction is nearly complete, the two-way on / off valve of the gas-liquid isolation piston is activated, and gas from one side of the pressure chamber rushes into the liquid storage chamber, which can completely extract the remaining liquid even when the liquid extraction port is at a low position, thus improving the utilization rate of the liquid.

Detailed Implementation

[0040] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description and are illustrated by specific illustrative embodiments in which the invention may be practiced. In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the invention. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the invention is defined by the appended claims.

[0041] This invention proposes a liquid storage device. Figure 1 A cross-sectional schematic diagram of a liquid storage device according to a first embodiment of the present invention is shown, as follows: Figure 1 As shown, the liquid storage device includes three main modular components: a liquid storage body 1, a liquid dispensing assembly 2, and a gas injection assembly 3. The liquid dispensing assembly 2 and the gas injection assembly 3 are installed at both ends of the liquid dispensing body 1, and their installation positions can be interchanged to realize the conversion of the internal gas-liquid chambers. This facilitates use and reduces damage to the internal piston sealing ring caused by frequent disassembly and assembly. The following is a detailed description of each modular component:

[0042] In a specific embodiment, the liquid storage body 1 is a hollow, straight-through cylindrical structure with symmetrically arranged functional, detachable sealing end caps at both ends of its opening. The end caps can be fixed to the liquid storage body 1 by means of snap-fit ​​or threaded connection. The liquid storage body 1 is also provided with a reciprocating gas-liquid isolation piston 4, which divides the internal space of the liquid dispensing body 1 into an inflation chamber and a liquid storage chamber. The installation positions of the corresponding liquid dispensing component 2 and gas injection component 3 in the inflation chamber and liquid storage chamber are determined by the installation positions of the liquid dispensing component 2 and the gas injection component 3. When the installation positions of the liquid dispensing component 2 and the gas injection component 3 are interchanged, the inflation chamber and the liquid storage chamber are also interchanged.

[0043] In a specific embodiment, the liquid storage body 1 can be a single-layer or double-layer structure. The double-layer structure can better protect the inner cavity and prevent external collisions from causing the gas-liquid isolation piston 4 to jam and the medium in the chamber to leak. At the same time, the interlayer can also play a role in heat preservation.

[0044] In a specific embodiment, the gas-liquid isolation piston 4 separates the interior of the liquid storage body 1 into a liquid storage chamber and an air filling chamber, preventing leakage of liquid and gas between the two chambers and ensuring normal operation of the device. The gas-liquid isolation piston 4 includes a piston body 41, a sealing ring 42, a sealing plate 43, a valve core 44, and a reset elastic body 45. The piston body 41 is a circular plate with a diameter smaller than the inner diameter of the liquid storage body 1, and a sealing ring 42 is provided on its outer edge to seal against the inner wall of the liquid storage body 1. The sealing plate 43 is located in the middle of the circular plate, and a through hole is provided in the middle. The valve core 44 passes through the through hole and is sealed against the through hole in the middle. A pair of reset elastic bodies 45 are symmetrically arranged at both ends of the valve core 44. In the static storage state, the valve core 44 passes through the hole and is press-fitted to form a seal. When liquid extraction is nearly complete, when either end of the valve core 44 triggers the liquid outlet assembly 2, the bidirectional on / off valve is opened, allowing gas from the air filling chamber side to rush into the liquid storage chamber, so that the remaining liquid can be completely extracted even when the liquid extraction port is at a low position. After the valve has finished taking liquid, opening the end cap will restore the sealing state under the action of the reset elastic body 45. In this way, the gas-liquid chamber can be switched by swapping the end caps, which is convenient to use and reduces the damage to the piston sealing ring caused by frequent disassembly and assembly.

[0045] Figure 2 The schematic cross-sectional view of the liquid outlet assembly according to a specific embodiment of the present invention is shown below. Figure 2As shown, the liquid dispensing assembly 2 includes a liquid dispensing body 21, a liquid dispensing head 22, a switching structure 23, and a liquid dispensing valve core structure 24. The liquid dispensing body 21 has a liquid dispensing cavity in its center to house the liquid dispensing valve core structure 24. A protruding connecting portion is formed in the center of its outer surface. The top of this connecting portion has a through hole communicating with the liquid dispensing cavity. The liquid dispensing head 22 is fitted onto this protruding connecting portion and is sealed to it. The liquid dispensing head 22 is hollow inside and has a liquid dispensing nozzle on one side communicating with the interior. The switching structure 23 is located on the liquid dispensing head 22. When activated, the switching valve core 231 triggers the liquid dispensing valve core structure 24 to control the opening or closing of the liquid dispensing cavity and the liquid dispensing nozzle of the liquid dispensing head 22.

[0046] In a specific embodiment, the dispensing valve core structure 24 includes a dispensing valve core 241, a bushing 242, a return spring 243, a sealing sleeve 244, and a valve core fixing seat 25. The valve core fixing seat 25 is fixedly disposed on the lower end face of the dispensing cavity, and its surface is perforated with multiple channels connecting the dispensing cavity and the storage cavity. The dispensing valve core 241 is fixedly disposed in the middle of the valve core fixing seat 25 (which can be achieved by threaded connection). The bushing 242 has a valve core cavity for accommodating the dispensing valve core 241. The return spring 243 is disposed between the dispensing valve core 241 and the valve core cavity. The sealing sleeve 244 covers the connection between the dispensing valve core 241 and the bushing 242, so that the valve core cavity of the dispensing valve core 241, the return spring 243, and the bushing 242 is separated from the flow channel to avoid affecting the quality of the internal stored liquid. A filter screen 26 is detachably mounted on the bottom of the liquid outlet assembly 2. One end of the liquid outlet valve core 241 extends out from the bottom of the valve core fixing seat 25. The filter screen 26 is detachably fitted to one end of the liquid outlet valve core 241 (it can also be connected by a threaded connection for easy installation and maintenance). The filter screen 26 can filter impurities in the liquid, ensuring the purity of the outflowing liquid and preventing foreign objects from being carried by the fluid, which could cause the sealing of the internal valve structure to fail.

[0047] Figure 3 A cross-sectional schematic diagram of an injection assembly according to a specific embodiment of the present invention is shown, such as... Figure 3 As shown, the air injection assembly in this embodiment is an airbag-type self-supplying structure, specifically including an air injection body 31, an airbag 32, a one-way check valve 33, and a one-way air inlet valve 34. The airbag 32 is mounted on the air injection body 31 and communicates with the inflation chamber inside the liquid storage body 1 through the one-way check valve 33 located on the air injection body 31. The one-way air inlet valve 34 is located at the mating point between the airbag 32 and the air injection body 31. When the air injection assembly 3 injects air into the inflation chamber, the gas enters the inflation chamber through the one-way check valve 33, pushing the gas-liquid isolation piston 4 to compress the liquid storage chamber, causing the internal liquid to flow out from the liquid outlet assembly 2.

[0048] In a specific embodiment, the inflation body 31 is composed of two parts: a base plate and a side cover. These two parts are interlocked, pressing the airbag 32 into a groove formed by their interlocking. The side cover pressure plate has an external air inlet valve port 341 and a cavity for accommodating the valve plate 342. The external air inlet valve port 341 is smaller than the valve plate 342. The airbag 32 has a corresponding airbag end valve port 343, which is designed in a quincunx pattern to improve air intake efficiency and stability, prevent gas backflow, and ensure effective manual inflation. The base plate has a groove at the corresponding valve port that connects to the interior of the airbag 32, allowing gas to enter the airbag 32.

[0049] Figure 4 A cross-sectional schematic diagram of a liquid storage device according to a second embodiment of the present invention is shown, as follows: Figure 4 As shown, with Figure 1 The liquid storage devices shown are similar, all adopting an independent air supply structure. The difference is that this embodiment uses a bellows air injection structure 310. The bellows air injection structure 310 has a return spring inside the bellows structure, which can automatically return to its original position after being pressed. The side cover is provided with a positioning guide groove, and the bottom cover of the bellows is provided with a one-way air intake valve structure. In order to prevent the one-way air intake valve from being blocked by hand when pressing to inflate, the positioning guide groove is used as an air intake channel (the gap between the bottom cover and the guide groove) to connect to the one-way air intake valve. The positioning guide groove also serves to balance the air pressure inside the bellows, so as not to affect the freedom of the bellows to extend and retract.

[0050] In other embodiments of this application, in addition to employing a self-supplying gas structure, an external gas supplying gas injection component can also be used, such as... Figure 5 A cross-sectional schematic diagram of a liquid storage device according to a third embodiment of the present invention is shown. Figure 6 A cross-sectional schematic diagram of a liquid storage device according to a fourth embodiment of the present invention is shown. Figure 5 In this embodiment, the external air supply structure I 320 includes a one-way air inlet 321 and a pressure relief valve 322. The one-way air inlet 321 is connected to an external air inflation device via an external inflation connector 5 to supply gas to the inflation chamber, and the pressure relief valve 322 serves as a safety protection function. This direct-supply air supply structure can also use an external air injection device to pressurize and store a suitable amount of gas in the pressure chamber without connecting an air inlet pipeline, meeting the needs of short-term liquid extraction. Figure 6In the embodiment, the external air supply structure II 330, in addition to including a one-way inlet nozzle 332 and a pressure relief valve 333, also includes a sealed chamber 331. Inside the sealed chamber 331, a pressure reducing valve 334 and a one-way inlet valve 335 for the inflation chamber are installed. Both external air supply structures are equipped with safety pressure relief valves to avoid the safety hazard of excessive inflation pressure. During use, high-pressure gas is first injected through the one-way inlet nozzle 332. The gas, after being regulated by the pressure reducing valve 334, enters the inflation chamber through the one-way inlet valve 335. Once the inflation chamber reaches the preset pressure, the input stops, and continued injection into the sealed chamber 331 achieves pressure storage. Without external piping, the sealed chamber 331 can continuously and stably supply gas to the inflation chamber, expanding its application scenarios. Due to the gas-liquid isolation effect of the gas-liquid isolation piston 4, clean air can be introduced into the inflation chamber. If high preservation requirements are needed, inert gases such as carbon dioxide, nitrogen, or argon, or mixtures thereof, can be used.

[0051] Figure 7 A cross-sectional schematic diagram of a liquid storage device according to a fifth embodiment of the present invention is shown, as follows: Figure 5 As shown, this embodiment employs another modular liquid-taking head 27, including a body and a trigger. The body is fitted onto the protruding connecting part of the liquid-dispensing body 2. The body is hollow and can communicate with the liquid-dispensing cavity. The trigger is fitted onto the body and sealed to it (through a sealing ring structure at the mating point). An elastic reset element can be provided at the mating point between the two. A liquid-taking head valve core 271 is provided on the trigger. A transverse limiting extension protrusion is provided on the outer circumferential surface of the trigger head, which can cooperate with an external bracket or fixed seat when the liquid storage device is inverted. In use, the bottom of the tank can be directly pressed, and the liquid-taking head valve core 271 abuts against the liquid-dispensing valve core structure 24 to open the liquid-dispensing channel. The liquid in the liquid storage cavity can flow out from the liquid outlet on the trigger, realizing automatic liquid-taking operation. The gas injection component used in this embodiment is... Figure 6 The external air supply structure II 330, which is the same as in the previous embodiment, can also use the air injection component 2 in the other embodiments mentioned above, and can achieve the same technical effect.

[0052] Continue to refer to Figure 8 , Figure 8 A flowchart of a liquid storage method according to an embodiment of the present invention is shown, as follows: Figure 8 As shown, the liquid storage method includes the following steps:

[0053] S1: Inject the liquid to be stored into the interior of the liquid storage body, and assemble the liquid outlet component and the gas injection component;

[0054] S2: Turn on the switch of the liquid outlet component, and inject air from the bottom air injection component in the vertical position;

[0055] S3: When the liquid to be stored flows out from the outlet of the liquid outlet component, close the switch to isolate the liquid storage chamber from the outside and complete the liquid storage operation.

[0056] The gas-liquid isolation piston inside the liquid storage body can movably divide the tank into two chambers: a liquid storage chamber and an air filling chamber. When the top liquid outlet is opened, air is injected from the bottom in a vertical position. When liquid flows out from the outlet, it indicates that the air venting in the liquid storage chamber is complete. When the switch is closed, the liquid storage chamber, which was originally connected to the outside, forms a sealed space. The space is filled with liquid and isolated from the outside, so the liquid will not come into contact with air and will be oxidized. This also reduces evaporation and is beneficial for the preservation of the liquid.

[0057] Figure 9 A flowchart of a liquid collection method according to an embodiment of the present invention is shown, as follows: Figure 9 As shown, this liquid extraction method, based on the aforementioned liquid storage method, further includes:

[0058] S4: Turn on the switch of the liquid outlet assembly, and use the air injection assembly to inject air to push the gas-liquid isolation piston to force the liquid out of the storage chamber;

[0059] S5: After the liquid in the storage chamber is completely removed, the liquid outlet component and the gas injection component are removed and cleaned. Then, the installation positions of the liquid outlet component and the gas injection component are adjusted, and S1-S4 are repeated to perform the liquid storage and liquid retrieval operations.

[0060] In daily use, there is no restriction on the liquid extraction posture of the liquid storage body. After injecting air into the air chamber, open the liquid extraction port switch, and the liquid can be quickly extracted under the push of air pressure. During the liquid extraction process, the liquid in the storage chamber does not come into contact with the outside air, which is conducive to continuous preservation.

[0061] It is evident that those skilled in the art can make various modifications and alterations to the embodiments of the present invention without departing from the spirit and scope of the invention. In this way, the invention is also intended to cover such modifications and alterations if they fall within the scope of the claims and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are described in mutually different dependent claims does not indicate that a combination of these measures cannot be used for profit. Any reference numerals in the claims should not be considered as limiting the scope.
