Description

Technical Field

[0001] The present application relates to the technical field of liquid cleaning products, and in particular to an extrusion foaming container. Background Art

[0002] In the related art, the gas and liquid of the squeeze foaming container come from the same cavity, and the gas and liquid channels are usually set in the same axial direction of the main body. When the bottle is squeezed, the gas and liquid are compressed at the same time. At this time, it is easy for the liquid to flood the gas inlet channel, causing liquid to enter the gas cavity, and finally causing the product to be unable to spray dense foam, directly spray liquid, etc. If you want to avoid this situation, you need to educate users to keep the product upright or at a small tilt angle when using it, but this will greatly reduce the user experience, and it is difficult for users to accurately grasp the angle of use.

[0037] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0038] In the description of the present application, it should be understood that descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0039] In the description of this application, "several" means one or more, "more" means at least two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0040] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application after combining the specific content of the technical solution.

[0041] It is understandable that the airway opening in the related art is generally designed on the main body component near the center upper end of the bottle body 100, so the actual foaming effect of the product is affected by multiple variables such as the filling volume, the shape design of the bottle body 100, and the operation method, as shown in the following situations:

[0042] ① The initial filling capacity is too full, the liquid level soaks the airway or after tilting at a certain angle, the liquid level soaks the airway.

[0043] ② The initial filling capacity is appropriate, but the liquid level rises when the bottle is tilted at a large angle or squeezed during use, causing the liquid level to penetrate the airway.

[0044] ③ When the initial filling capacity is low or the liquid level has been used to a low position, the liquid level in the extreme use state will penetrate the airway

[0045] When the above situation occurs, it is easy to cause the liquid to penetrate the airway, resulting in the spraying of liquid or thin bubbles or unstable bubbles.

[0046] Reference Figures 1 to 7 The squeeze foaming container of the first embodiment of the present application includes a bottle body 100, a bottle cover component 200 and a foaming component 300.

[0047] The bottle body 100 includes a bottle mouth 110 and a bottle bottom 120 opposite to the bottle mouth 110; the bottle cap component 200 is arranged on the bottle body 100, and the bottle cap component 200 has a bubble outlet 211 facing a preset direction; the bubble outlet component 300 includes a bubble component 310, a liquid inlet component 320 and an air inlet component 330, the bubble component 310 is arranged at the bottle mouth 110, the first end of the bubble component 310 is connected to the bubble outlet 211, and the second end of the bubble component 310 is sealed and connected to one end of the liquid inlet component 320 and one end of the air inlet component 330 respectively; the other end of the liquid inlet component 320 is relatively close to the bottle bottom 120 and faces the same side as the bubble outlet 211, and the other end of the air inlet component 330 is relatively close to the bottle mouth 110 and faces the opposite side of the bubble outlet 211, so that the other end of the liquid inlet component 320 and the other end of the air inlet component 330 are diagonally distributed in the bottle body 100.

[0048] It is understandable that by increasing the circumferential distance between the liquid inlet assembly 320 and the air inlet assembly 330, the air inlet assembly 330 is arranged at the far end of the shoulder of the bottle body 100 in the opposite direction to the product bubble outlet 211, and the air inlet and the liquid inlet are respectively located in the diagonal direction of the bottle body 100. When the product is tilted and squeezed, the liquid inlet is always located on the side of the product bubble outlet 211, and the air inlet is always located on the opposite side of the product bubble outlet 211, thereby ensuring the stability of gas-liquid mixing.

[0049] In some embodiments, the first end of the bubble component is connected to the bubble outlet 211 through a channel in the bottle cap component 200, one end of the liquid inlet component 320 and one end of the air inlet component 330 serve as output ends, and the other end of the liquid inlet component 320 and the other end of the air inlet component 330 serve as input ends (liquid inlet, air inlet) so that gas and liquid are mixed at the second end of the bubble component 310 to form foam.

[0050] It should be noted that by increasing the circumferential distance between the air inlet channel and the liquid inlet channel, the air inlet channel is set at the far end of the shoulder of the bottle body 100 in the opposite direction to the product bubble outlet 211, and the air inlet channel opening and the liquid inlet channel opening are respectively located in the diagonal direction of the bottle body 100. When the product is tilted and squeezed, the liquid inlet channel opening is always located on one side of the product bubble outlet 211 and the lowest point in the vertical direction of gravity (the lowest point of the liquid), and the air inlet channel opening is always located on the opposite side of the product bubble outlet 211 and the highest point in the vertical direction of gravity (except the bottle mouth 110). In this way, it is ensured that when the user squeezes within the tilt range of 0-90° (or even a larger angle), the liquid inlet channel opening is always immersed in the liquid, and the air inlet channel opening is always farthest from the liquid level line, thereby achieving a stable gas-liquid mixed foaming effect.

[0051] In some embodiments of the present application, the bubbler component 300 includes an air inlet sleeve assembly 340 and a one-way valve assembly 350. The air inlet sleeve assembly 340 is arranged at the bottle mouth 110 and is respectively connected to one end of the liquid inlet assembly 320 and one end of the air inlet assembly 330. The bubbler assembly 310 is arranged on the air inlet sleeve assembly 340 and is connected to the air inlet sleeve assembly 340. It can be understood that the one-way valve assembly 350 cancels the one-way glass bead return valve design integrated on the body in the related art, and is adjusted to be a separate component installed on the air inlet sleeve assembly 340, which is used as a channel for rapid air return and air replenishment after the product is squeezed, replacing the function of the one-way glass bead valve on the original body. The top surface of the air inlet sleeve assembly 340 is designed to be concave around the bubbler assembly 310 as the return channel, mainly to ensure that when it is in place, it can also facilitate air return.

[0052] In some embodiments, a screw thread that cooperates with the lower cover 220 is added to the upper end of the air inlet sleeve assembly 340, and a buckle structure that cooperates with the bottle mouth 110 is added to the lower end.

[0053] In some embodiments of the present application, the air inlet sleeve assembly 340 is formed with an air return portion 341, the outer end of the air return portion 341 can be connected to the outside of the bottle body 100, and the inner end of the air return portion 341 is connected to the inside of the bottle body 100. The one-way valve assembly 350 is arranged on the air inlet sleeve assembly 340 and is used to make the air return portion 341 unidirectional along the direction from the outer end of the air return portion 341 to the inner end of the air return portion 341. It can be understood that since the air return channel originally designed in the bubbler assembly 310 is designed to the air inlet sleeve assembly 340, and the one-way valve assembly 350 also replaces the original one-way glass bead valve on the body, the one-way glass bead valve loses its function. Therefore, the bubbler assembly 310 is adjusted to remove the one-way glass bead valve. The design of the air return channel in the air inlet sleeve assembly 340 can also save the design of sealing connection of multiple components, thereby optimizing the overall structure.

[0054] In some embodiments, in order to simplify the structure of the foaming component 310 and reduce the thickness of the product as much as possible, the diameter of the body is compressed as much as possible.

[0055] In some embodiments of the present application, the air return portion 341 includes a first air return channel 3411 and at least one air return hole 3412 arranged on the first air return channel 3411, the first air return channel 3411 is formed on the top surface of the air inlet sleeve assembly 340 and is located outside the bottle body 100, one end of the air return hole 3412 is connected to the first air return channel 3411, and the other end of the air return hole 3412 is connected to the bottle body 100; it can be understood that the top surface of the air inlet sleeve assembly 340 is provided with a plurality of air return holes 3412 as air inlets, and the air inlets are connected through the air return channel formed by the top surface groove, thereby ensuring smooth gas circulation inside the product.

[0056] In some embodiments, the spring portion 352 of the one-way valve assembly 350 is designed as a full-circle spring, so that the air intake channel is wider. When the air intake volume is larger, the bottle body 100 returns air faster, which can meet the product's needs for fast and continuous extrusion.

[0057] In some embodiments of the present application, the one-way valve assembly 350 includes a mounting portion 351 and a spring portion 352 disposed on the mounting portion 351, the spring portion 352 being disposed on the bottom surface of the air inlet sleeve assembly 340, the mounting portion 351 being disposed against the other end of the return air hole 3412, and the mounting portion 351 being capable of sealing the return air hole 3412 when the bottle body 100 is under pressure, and opening the return air hole 3412 when the bottle body 100 rebounds, until the spring portion 352 rebounds to reset the mounting portion 351 when the internal and external air pressures of the bottle body 100 are balanced. It can be understood that the spring of the spring-type one-way valve is warped upward, and the spring is pressed against the bottom of the inner side of the bottle cap base. When the product is stationary and the bottle body 100 is under pressure, the spring is pressed and sealed with the bottle cap base to ensure that the liquid does not flow out. When the bottle body 100 rebounds, negative pressure is generated in the bottle, the spring is pressed downward and opens, and external gas enters, until the internal and external air pressures of the bottle body 100 are balanced, and the spring rebounds to close the seal.

[0058] In some embodiments, the one-way valve assembly 350 is optimized as a spring-type one-way valve, which is sealed with the air intake sleeve assembly 340 through a circumferential buckle line and an interference seal.

[0059] In some embodiments of the present application, the bottle cap component 200 includes an upper cover 210 and a lower cover 220, the bubble outlet 211 is arranged on the upper cover 210, the lower cover 220 is arranged on the bottle body 100 and is located at the periphery of the bottle mouth 110, and the upper cover 210 and the lower cover 220 can be assembled together in an openable and closable manner so that the first end of the bubbler component 310 can be connected or cut off with the bubble outlet 211. It can be understood that the upper cover 210 and the lower cover 220 are sealed by circumferential interference, and the positioning and limiting are achieved by the axial buckle line for opening and closing. When the product is in a closed state, the bubble outlet channel (interference seal between the upper cover 210 and the lower cover 220) and the return air channel are closed (interference seal between the upper cover 210 and the lower cover 220).

[0060] In some embodiments, drainage holes are provided around the inner wall of the lower cover 220. When the product is used in a water washing scenario, water entering through the gap between the upper cover 210 and the lower cover 220 can flow out through the drainage holes of the lower cover 220, thereby preventing water accumulation and dirtiness in the product.

[0061] In some embodiments, the lower cover 220 and the bottle body 100 are matched by buckle or thread, and the circumferential positioning / directional assembly between the lower cover 220 and the extruded bottle body 100 is achieved by a stop point structure. The positioning structure can be a conventional positioning groove and positioning stop point matching method, which can be one or more sets of positioning structures.

[0062] In some embodiments, a corresponding concave-convex positioning structure is provided between the upper cover 210 and the lower cover 220 to enhance the user's recognition of the product's open and closed status during use, and to avoid leakage during carrying due to forgetfulness or confusion. Furthermore, some suggestive lettering can be added on or near the concave-convex positioning stop points (such as the upper and lower sides), or the color feedback of different parts can be changed to quickly and accurately determine whether it is closed in place.

[0063] In some embodiments of the present application, the opening and closing gap between the upper cover 210 and the lower cover 220 serves as a second air return channel 230, and a third air return channel 240 is formed between the lower cover 220 and the bottle body 100. The second air return channel 230 and the third air return channel 240 can respectively connect the air return part 341 and the atmosphere; it can be understood that by targeted design of the positions of the second air return channel 230 and the third air return channel 240 to fully supply air to the first air return channel 3411, smooth circulation of gas inside the product is ensured.

[0064] In some embodiments, the second air return channel 230, the third air return channel 240 and the other end of the air inlet assembly 330 are located on the same side. It is understandable that designing the second air return channel 230 and the third air return channel 240 on one side can reduce the distance of gas flow so that the bottle body 100 can return air faster, which can meet the fast and continuous extrusion requirements of the product.

[0065] In some embodiments of the present application, the liquid inlet assembly 320 includes a curved pipe 321 and a guide member 322, the guide member 322 is sealed and connected to the air inlet sleeve assembly 340, one end of the curved pipe 321 is sealed and connected to the guide member 322, and the other end of the curved pipe 321 extends to a corner position of the bottle bottom 120 and faces the same side as the bubble outlet 211; it can be understood that the design of the curved pipe 321 is utilized to adapt to the specific shape of the bottle body 100, thereby ensuring that the liquid inlet of the liquid inlet assembly 320 can always be located at the bottom to ensure the stability of the bubble effect.

[0066] In some embodiments, the lower end of the air inlet sleeve assembly 340 is directly fitted with the liquid inlet assembly 320 in an interference seal. The liquid inlet assembly 320 is provided with a guide slot, the main purpose of which is to guide the liquid inlet pipe to ensure that the liquid inlet pipe and the liquid outlet nozzle maintain the same direction, 180° in the opposite direction of the inlet gas.

[0067] In other embodiments, the lower end of the air intake sleeve assembly 340 is connected to the directional member 333 of the air intake assembly 330, and then the directional member 333 is provided with connecting openings respectively connecting the lower end of the air intake sleeve assembly 340 and the guide member 322, so that the guide member 322 is indirectly connected to the lower end of the air intake sleeve assembly 340 through the directional member 333, and the lower end of the air intake sleeve assembly 340 is in interference sealing fit with the liquid inlet assembly 320.

[0068] In some embodiments, the air intake pipe 331 arranged on the directional member 333 may be a hard pipe or a soft pipe, and it will be described in detail below how the hard pipe or the soft pipe can achieve the upward tilt of the air intake end. The above two embodiments are only used to illustrate the connection relationship between the air intake sleeve assembly 340 and the air intake assembly 330 and the liquid intake assembly 320, and the air intake pipe 331 can be further adaptively arranged on this basis.

[0069] In some embodiments of the present application, the bubble generating assembly 310 includes a main body 311, a diverter valve 312 and a network structure 313. A mounting port 342 is formed on the top surface of the air inlet sleeve assembly 340. The main body 311 is disposed in the mounting port 342. The main body 311 has a gas-liquid channel 3111 for respectively connecting the bubble outlet 211 and the air inlet sleeve assembly 340. The diverter valve 312 and the network structure 313 are disposed in the gas-liquid channel 3111 so that the gas and liquid input into the air inlet sleeve assembly 340 pass through the diverter valve 312 and the network structure 313 in sequence and are output from the bubble outlet 211. It can be understood that the main body 311 is nested inside the air inlet sleeve assembly 340 through circumferential interference and buckle lines, the central channel of the main body 311 is the gas-liquid channel 3111, and the main body 311 is equipped with a net and a diverter valve 312. When the gas and liquid in the cavity are squeezed, they are foamed and dispensed through the diverter valve 312 and the net. In some embodiments, a one-way valve assembly 350 is used to seal the gas and liquid in the cavity, ensuring that the gas and liquid in the cavity enter the main body diverter valve 312 and the net from the air inlet and the liquid inlet.

[0070] In some embodiments of the present application, the top surface periphery of the air inlet sleeve assembly 340 is provided with a first thread structure 343, the inner side of the lower cover 220 is provided with a second thread structure 221 that matches the first thread structure 343, the inner side of the side wall of the air inlet sleeve assembly 340 is provided with a first stop point buckle structure 344, and the outer periphery of the bottle mouth 110 is provided with a second stop point buckle structure 111 that matches the first stop point buckle structure 344. It can be understood that the top surface periphery of the air inlet sleeve assembly 340 is designed as the first thread structure 343, which can not only be conveniently assembled with the lower cover 220, but also can be conveniently removed when performing a liquid replenishment operation, and the first thread structure 343 is used to cooperate with the thread structure of the liquid replenishment component, thereby improving applicability.

[0071] In some embodiments, the first stop point buckle structure 344 and the second stop point buckle structure 111 can play a positioning and assembly effect and ensure the installation accuracy of the air intake sleeve assembly 340.

[0072] In some embodiments of the present application, the air intake assembly 330 includes an air intake pipe 331 and a buoyancy member 332. The air intake pipe 331 is a hose. One end of the air intake pipe 331 is connected to the second end of the foaming assembly 310. The buoyancy member 332 is arranged closer to the other end of the air intake pipe 331 relative to one end of the air intake pipe 331, so that the other end of the air intake pipe 331 can be tilted upward when there is a preset volume of liquid in the bottle 100. It can be understood that the air intake assembly 330 adopts a hose + buoyancy ball structure. The buoyancy ball can ensure that the air intake end of the hose is always on the liquid surface, and the air intake channel is not affected by factors such as the product tilt angle and the liquid level rise when the product is squeezed, thereby ensuring the stability of the gas-liquid mixing when the product is squeezed.

[0073] In some embodiments, the length of the air inlet pipe 331 is set according to the shape and size of the bottle body 100. When the product is tilted (when the bottle shoulder 130 is at the highest point), the buoyancy ball and the air inlet can be extended to the highest point of the bottle shoulder 130, thereby preventing the buoyancy ball and the air inlet from being pulled and submerged below the liquid surface due to insufficient length of the air inlet pipe 331.

[0074] In some embodiments of the present application, the air intake component 330 includes a directional member 333 and an air intake pipe 331, the air intake pipe 331 is a hard pipe, one end of the directional member 333 is connected to the second end of the bubbler component 310, and the other end of the directional member 333 is sealed and connected to the air intake pipe 331 and is used to limit the direction of the air intake pipe 331, so that the other end of the air intake pipe 331 is tilted upward at a preset angle with the axis of the bubbler component 310. It can be understood that the directional member 333 plays a role in orienting the air intake pipe 331, which can solve / avoid the situation that the liquid enters the airway during normal squeezing use, and also reduces the probability of the liquid entering the airway under extreme use / squeezing use. In some embodiments, the straw adopts a curved directional design, the liquid inlet channel opening of the liquid inlet pipe is always in the same direction as the bubble outlet 211 of the product, and the liquid inlet channel opening is always located at the bottom of the vertical direction of the gravity of the cavity.

[0075] In some embodiments, the air inlet pipe 331 is optimized to be a V-shaped pipe, which is easier to assemble than a horizontal pipe and has a pouring effect when loaded from the bottle mouth 110. In addition, the V-shaped pipe is more convenient for mold forming.

[0076] In some embodiments, a directional member 333 is provided at the bottom of the air inlet sleeve assembly 340, and the directional member 333 is used to transfer the air inlet channel opening to the opposite distal end of the cavity relative to the product bubble outlet 211. The air inlet sleeve assembly 340 and the directional member 333 are matched by circumferential interference and buckle line sealing, and the directional member 333 and the air inlet pipe 331 are interference fit.

[0077] In some embodiments, the directional member 333 and the air inlet pipe 331 are detachably sealed and connected, and in other embodiments, the directional member 333 and the air inlet pipe 331 can also be made into an integral body. Further, the shape of the bottle body 100 is suggested to be a waist-like shape, that is, the liquid inlet channel opening and the air inlet channel opening are always located at the farthest end of the diagonal line of the cavity.

[0078] In some embodiments of the present application, the bottle body includes a bottle shoulder 130 and a bottle body 140, one end of the bottle shoulder 130 is adjacent to the bottle mouth 110, and the bottle body 140 is located between the other end of the bottle shoulder 130 and the bottle bottom 120, and an introduction slope 131 is provided on the inner side of the bottle shoulder 130, one end of the introduction slope 131 is connected to the bottle mouth 110, and the other end of the introduction slope 131 extends to the position close to the connection between the other end of the bottle shoulder 130 and the bottle body 140, and the introduction slope 131 is used to guide the setting position of the other end of the air inlet pipe 331. It can be understood that by optimizing the structural design of the bottle body 100, the introduction slope 131 is used to guide the air inlet pipe 331 introduced by the assembly, which can not only facilitate the introduction of the air inlet pipe 331, but also ensure the position accuracy of the assembly, so that the other end of the air inlet pipe 331 can be reliably located at a corner position in the bottle body 100.

[0079] Reference Figures 1 to 7 The method for using the extrusion foam container of the second embodiment of the present application may be the method for using the extrusion foam container of the first embodiment of the present application, and the method for using the extrusion foam container comprises the following steps:

[0080] The upper cover 210 is pulled up relative to the lower cover 220 to make the first end of the bubbler assembly 310 communicate with the bubble outlet 211, and the bottle body 140 of the bottle 100 is squeezed to make the one-way valve assembly 350 seal the gas return portion 341, and the gas in the bottle 100 is combined with the liquid delivered by the liquid inlet assembly 320 through the gas inlet assembly 330 and is foamed in the bubbler assembly 310, and finally output from the bubble outlet 211;

[0081] When the squeezing is finished, the one-way valve assembly 350 opens the air return portion 341 due to the air pressure, and the external air enters the bottle body 100 through the air return portion 341. The bottle body 140 that has been squeezed and deformed gradually recovers until the one-way valve assembly 350 closes the air return portion 341 again, and the upper cover 210 is pressed relative to the lower cover 220 to cut off the first end of the bubbler assembly 310 and the bubble outlet 211.

[0082] It can be understood that the operation of the extrusion foaming device can be divided into four stages: opening → extrusion → air return → closing. The specific steps are as follows:

[0083] When in the open state, the assembly formed by the top cover and the upper cover 210 is pulled up through the pull ring in the middle of the top of the product to open the pump head. Since the pressure inside the bottle is the same as that outside, when the bottle body 140 is squeezed in normal use, the bottle body 140 is pressurized, the volume of the space inside the bottle becomes smaller, and the pressure inside the bottle becomes larger. The one-way valve can form a seal inside and outside the bottle. The gas in the bottle passes through the air inlet pipe 331 and merges with the liquid flowing upward through the liquid inlet pipe at the preparatory foaming position (the lower end of the diverter valve 312), and then preliminary foaming is carried out through the small holes of the diverter valve 312, and then foaming is carried out layer by layer through the lower and upper filters of the net. The higher the foam goes, the more and finer the meshes it passes through become layer by layer, and the foam becomes more and more dense, and finally pumped out from the foam outlet.

[0084] When squeezing is finished, the hand squeezing the bottle body 140 is released, and the inside of the bottle body 140 is in a negative pressure state. At this time, the one-way valve sealing position is opened, and the external air enters the bottle through the one-way valve and the liquid outlet channel (mainly the one-way valve channel) to quickly replenish the air, and the squeezed and deformed bottle body 140 begins to slowly recover. When use is finished, the assembly formed by the top cover and the upper cover 210 is pressed down into place, and the product is in a closed state.

[0085] It is understandable that in order to improve the user experience, products with too small a capacity sometimes need to be replenished with liquid. There are two conventional replacement and replenishment methods. The first is to directly open the matching structure between the pump and the bottle and directly fill the bottle with the contents; the second is to replace the contents with a new bottle. Both of these replacement and replenishment methods require the pump head to be removed first, exposing the contents to the air, which can easily cause contamination of the contents. In addition, the contents remaining on the pump head can easily slip and stain the ground, clothes or body, affecting the user experience, and the contents exposed to the air can also cause spillage and leakage.

[0086] In some embodiments of the present application, a method for replenishing liquid in a squeeze foaming container includes:

[0087] Remove the bottle cap component 200 from the bottle body 100;

[0088] Assemble the supplementary component 400 to the top surface of the air inlet sleeve assembly 340 and connect it to the first end of the bubbler assembly 310;

[0089] The refilling unit 400 is used to refill the squeeze foam container with liquid.

[0090] It can be understood that since the bottle cap component 200, the bubbler component 310, the one-way valve component 350 and the air intake sleeve component 340 are designed as independent components respectively in the present application, there is no need to open the matching structure between the pump and the bottle or remove the pump head when replenishing the liquid, thereby avoiding the difficulties encountered in liquid replenishment in the related art and improving the user experience.

[0091] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
