Description

Technical Field

[0001] This invention relates to the fields of home, catering, laboratory, and pharmacy, and specifically to a container that facilitates the storage and retrieval of items. Background Technology

[0002] Currently, there is a type of modular bottle cap on the market, along with matching condiment bottles for storing solid granular substances and liquids. The cap has a handle at the top and a tool at the bottom for retrieving items; these two components are integrated. The tool includes a spoon, brush, and honey extractor. Squeezing the cap handle is equivalent to simultaneously gripping the tool. Closing the cap with the bottle neck places the tool inside the bottle. Compared to condiment bottles with separate caps and tools, this simplifies many steps. Especially in kitchen environments where workers' hands are often wet, the ability to directly grip the cap handle prevents moisture from entering the bottle and affecting the preservation of the contents. These advantages have made this type of condiment bottle popular. However, this type of condiment bottle also has several disadvantages, which will be analyzed below.

[0003] When the bottom of the cap of this type of bottle is a spoon, and the spice bottle contains powdery or granular solids (hereinafter referred to as granules), such as salt, iron powder, or silver powder, the spoon's insertion depth into the granules is limited due to the size, density, and friction of the granules, making it difficult to close the cap and causing a seal failure. Therefore, the spoons used in these spice bottles currently only scoop about 1 gram at a time. Increasing the amount scooped at a time requires increasing the spoon size, making it even more difficult to insert the spoon into the granules and close the cap. When scooping larger amounts, such as 5 grams, 10 grams, or 50 grams, using a small spoon that scoops about 1 gram at a time is very inconvenient. Similarly, when dealing with large granules, such as rock sugar or pickles, using a small spoon that scoops about 1 gram at a time is also inconvenient, and the cap is difficult to close. Furthermore, these spice bottles have a small capacity, generally around 300 ml, not exceeding 500 ml. Increasing the capacity would increase the length of the spoon handle, which, when there are many granules in the bottle, also makes it difficult to close the cap. However, people have various needs when dealing with different types of particulate matter in homes, restaurants, supermarkets, laboratories, pharmacies, and other settings. People need spoons of different sizes to scoop up various particles; they also need 500ml or even larger bottles to store them. Furthermore, this type of spoon is fixedly connected to the bottle cap and has a gap between it and the bottom of the bottle, making it inconvenient to scoop out small amounts of particles from the bottom. Patent number "202020951191.0", patent name "A Spoon with a Retractable Handle and Lid", describes a spoon and lid that are movably connected, requiring two hands to adjust. In actual use, the amount of contents in the bottle changes constantly, requiring frequent adjustments of the spoon with both hands, which is time-consuming and inconvenient. Additionally, if hands are wet when adjusting the spoon, they must be dried first to avoid wetting the spoon; if the other hand is holding something else, it must be put down first. It should be noted that disabled individuals with only one functional hand cannot adjust this type of spoon with one hand. Furthermore, this type of spoon lacks the features and functions of a fork or slotted spoon.

[0004] When the bottom of the bottle cap is a brush, the condiment bottle is filled with liquid, such as cooking oil. This type of brush generally doesn't touch the bottom of the bottle, making it difficult to pick up even small amounts of liquid. When the cap and bottle are closed, the upper part of the brush is often submerged in the cooking oil. However, people only need the lower bristles of the brush to pick up oil; if other parts of the brush are contaminated, it's inconvenient to use and affects the amount picked up each time. This also leads to the brush easily contaminating the cap and bottle opening, causing leaks.

[0005] When using a honey dispenser, the bottom of the cap is for collecting semi-fluid substances such as honey or jam. The dispenser typically doesn't touch the bottom of the bottle, making it difficult to collect even small amounts of the substance. When the cap and bottle are closed, the top of the dispenser is often submerged in the semi-fluid. However, people only need to collect the substance from the bottom, the spherical part of the dispenser. If other parts of the dispenser are contaminated, it's inconvenient to use, leading to contamination and waste. Summary of the Invention

[0017] Furthermore, the locking device is a bow plate, which is U-shaped and made of an elastic hard material. There is a gap between the bow plate and the object-retrieving device. One side of the bow plate corresponds to the diaphragm, and a contact point is provided on the lower side of the bow plate. The contact point corresponds to the object-retrieving device and can lock and release the object-retrieving device.

[0018] Furthermore, the locking device is a pry bar, with a pressing part on one side that connects to the diaphragm.

[0062] Example 1: As Figure 1-8 As shown, a combined bottle cap and a condiment bottle having the bottle cap are disclosed. The bottle cap includes an upper half cap 1, a lower half cap 7, a diaphragm 3, a sealing ring 5, a picking device, and a locking device. The bottle cap and the bottle body 6 together form a condiment bottle.

[0063] The specific features are as follows: The upper half-cover 1 has an upwardly protruding handle in the middle, with a cavity in the middle that connects to the bottom of the upper half-cover 1. The handle's side wall has a through hole, and a diaphragm 3 is installed at the through hole. The diaphragm 3 is made of an elastic, soft material, such as silicone, rubber, or TPE. The diaphragm 3 has a "C"-shaped cross-section and is bonded to the edge of the through hole in the handle without any gaps, thus sealing the through hole. Alternatively, the diaphragm 3 can be made using a two-stage injection molding process, i.e., liquid silicone or TPE is directly injection molded and bonded to the through hole in the handle at a suitable temperature to form the diaphragm 3. A ring of bosses is provided at the lower edge of the upper half-cover 1, which contacts and engages with a ring of bosses at the upper edge of the lower half-cover 7 for positioning. The lower half-cover 7 has a through hole in the middle, with a boss at the upper edge of the through hole. A groove is provided on the right side of this boss, and this groove connects to the side wall of the through hole in the lower half-cover 7. The upper half cover 1 and the lower half cover 7 are connected by snaps to form the cover body. Figure 8As shown, the upper surface of the lower half-cap 7 has two upward-facing sidewall protrusions with hooks. These two protrusions hook into the grooves on the inner wall of the handle cavity of the upper half-cap 1, forming a snap-fit ​​connection. A sealing ring 5 is provided on the outer wall of the cap, which fits snugly against the bottle opening of the bottle body 6, and the lower half-cap 7 contacts the bottle opening of the bottle body 6. (The bottle body 6 is divided into three sections according to diameter, from top to bottom: bottle opening, bottle neck, and bottle body. The diameter of the bottle neck is smaller than that of the bottle opening, which is beneficial for sealing the cap and also makes it easier to grip the bottle neck.) The upper end of the retrieval device is always located inside the cavity of the cap, and the lower end of the retrieval device is always located outside the cap. The middle end of the retrieval device moves up and down within the through hole in the middle of the lower half-cap 7, with a clearance fit between the two. A locking device is provided inside the cavity of the cap. One end of this device corresponds to the diaphragm 3, and the other end corresponds to the retrieval device, controlling the up and down movement of the retrieval device within the through hole of the lower half-cap 7.

[0064] The described object-retrieving device includes a long rod 2 and a spoon head 8. The long rod 2 is slender, with a long rod cap at its top, shaped like a nail head, with a diameter larger than the diameter of the through hole in the lower half of the cover 7, preventing the long rod 2 from separating from the cover. The upper end of the object-retrieving device is the long rod cap of the long rod 2, which is always located inside the cavity of the cover. The lower end of the long rod 2 is inserted into the middle through hole of the lower half of the cover 7. The bottom end of the long rod 2 is connected to the top of the spoon head 8, i.e., the bottom end of the long rod 2 has a short pin, and the top end of the spoon head 8 has a blind hole, into which the short pin is inserted, with an interference fit between the two. The cross-section of the short pin and the blind hole is square, but can also be elliptical or polygonal to facilitate determining the axial position. The long rod 2 and the spoon head 8 can also be threaded or snap-fitted together. The upper end of the spoon head 8 has a short handle, and the lower end of the spoon head 8 has a recess for scooping particles. The lower end of the object-retrieving device is the lower recess of the spoon head 8, which is always located outside the cover. The middle part of the object-retrieving device includes a long rod 2 with the long rod cap removed and a short handle at the upper end of the spoon head 8. The middle part of the object-retrieving device is fitted with the through hole of the lower half cover 7 with a clearance, and can move up and down within this hole. Figure 2 Figure 3 As shown, the cross-section of the middle part of the lifting device is square, but it can also be elliptical, "D"-shaped, or polygonal. The cross-sectional shape of the through hole in the lower half of the cover 7 is the same, so that the lifting device can only move up and down and cannot rotate along its own axis. This keeps the axial position of the diaphragm 3 and the spoon head 8 fixed for easy operation.

[0065] The described object-retrieving device includes a long rod 2 and a brush head. The brush head includes a short brush handle 9 and a bristle body 10. The short brush handle 9 is made of a hard material, and the top of the short brush handle 9 has a blind hole or a through hole, which connects to... Figure 1 The short pin at the bottom of the long rod 2 is connected. (Connect the two rods together) Figure 1(The spoon head 8 is removed.) The brush body 10 is made of a flexible, soft material, such as silicone. Both the upper end of the brush body 10 and the lower end of the short brush handle 9 have cavities. The lower end of the short brush handle 9 is inserted into and clamps the cavity of the brush body 10, forming a sealed cavity. The lower end of the brush body 10 has several long, thin bristles. The lower end of the picking device is the brush body 10, which is always located outside the cover. The middle part of the picking device includes the long rod 2 (excluding the long rod cap) and the upper part of the short brush handle 9. The middle part of the picking device is fitted with the through hole of the lower half cover 7 with a clearance, allowing it to move up and down within this hole.

[0066] The described extraction device includes a long rod 2 and a honey-collecting stick head 11. The honey-collecting stick head 11 has a short handle at its upper end, and a blind hole at the top of the short handle, which connects to... Figure 1 The short pin at the bottom of the long rod 2 is connected. (Connect the short pin at the bottom of the long rod 2) Figure 1 (The spoon head 8 is removed.) The lower end of the honey-collecting stick 11 has a sphere with several grooves on its outer side. A sealed cavity is located in the middle of the sphere. This cavity is simple to make; first, make the cavity that communicates with the outside, and then block the hole that communicates with the outside. Alternatively, the honey-collecting stick 11 can be made in two halves and then glued or welded together as a whole. Or, the blind hole at the top of the honey-collecting stick 11 can be changed to a through hole, which communicates with the cavity at the lower end of the honey-collecting stick 11 and can be sealed by the short pin of the long rod 2. The lower end of the picking device is the sphere at the lower end of the honey-collecting stick 11, and it is always located outside the cover. The middle part of the picking device includes the slender part of the long rod 2 excluding the long rod cap and the upper part of the honey-collecting stick 11. The middle part of the picking device is fitted with the through hole of the lower half of the cover 7 with a clearance, and can move up and down within this hole.

[0067] The locking device is a bow plate 4, which is generally U-shaped and made of a flexible but rigid material, such as spring steel. The bow plate 4 is locked into the cavity of the upper cover 1. Several ribs are located on both sides of the bow plate 4 on the inner wall of the upper cover 1 cavity, serving to fix the bow plate 4. A boss is located on the left side of the lower cover 7, contacting the bottom left end of the bow plate 4, also serving to fix the bow plate 4. A gap is left between the bow plate 4 and the long rod 2 to facilitate the movement of the long rod 2. The middle right end of the bow plate 4 corresponds to the diaphragm 3; the two are in direct contact or with a gap fit. The diaphragm 3 will not be squeezed by the bow plate 4, causing deformation and affecting its appearance. A contact point is located at the lower right end of the bow plate 4. The bottom end of the contact point inserts into the groove on the right side of the through hole in the lower cover 7, so the contact point can only move left and right. The contact point corresponds to the object-retrieving device, and the two are in a gap fit. The contact point is bent multiple times to fit the shape and size of the long rod cap.

[0068] Usage and Principle of Example 1: When the dispensing device is a combination of a long rod 2 and a spoon head 8, the bottle body 6 is suitable for holding granules. During storage, the bottle cap and bottle body 6 are separated, and a certain amount of granules is added into the bottle from the bottle opening. Then, holding the handle of the cap with one hand, the spoon head 8 is inserted into the bottle opening. Without pressing the diaphragm 3, the contact point of the bow plate 4 does not contact the dispensing device. Because the middle of the dispensing device is fitted with the through hole of the lower half of the cap 7, when the spoon head 8 is not in contact with the granules inside the bottle, the dispensing device will automatically slide downwards under its own weight until the long rod cap abuts the upper end of the through hole of the lower half of the cap 7. When the spoon head 8 comes into contact with the granules inside the bottle, the granules exert pressure on the spoon head 8, pushing the middle of the dispensing device into the cavity of the cap. Without inserting the spoon head 8 into the granules, the bottle cap easily closes with the bottle opening, and the sealing ring 5 seals tightly against the bottle opening, completing the storage operation. When scooping out the particles from the bottle, hold the handle of the cap with one hand to separate the cap from the bottle body 6. Do not press the diaphragm 3 initially. Let the long rod 2 slide down through the through-hole of the lower half of the cap 7 until the long rod cap touches the upper end of the through-hole. Then, holding the handle of the cap, press the diaphragm 3 again. The diaphragm 3 deforms, compressing the arch plate 4. Figure 7 As shown, the contact point at the lower right end of the bow plate 4 contacts the retrieval device. The contact point, after multiple bends, locks the long rod cap, locking the long rod 2 and preventing it from moving up and down. Alternatively, if the long rod 2 does not move to its lowest position, pressing the diaphragm 3 causes the contact point of the bow plate 4 to contact the middle side wall of the retrieval device, similarly locking the retrieval device. Next, insert the spoon head 8 into the bottle, filling the recessed part of the spoon head 8 with granules. Lift the handle of the cap to remove the granules contained in the spoon head 8 from the bottle, completing the scooping operation. The entire scooping operation only requires pressing the diaphragm 3 before inserting the spoon head 8 into the granules; the pressing time is short, and the operation is simple and convenient. Since the spoon head 8 does not need to be inserted into the granules in the bottle to seal the storage, the size of the spoon head 8 can be large or small. The size of the recessed part at the lower end of the spoon head 8 only needs to be smaller than the inner diameter of the bottle neck 6. Different sizes of spoon heads 8 mean different scooping amounts per time, meeting the needs of various sized granules and usage amounts. A spice bottle can be fitted with multiple spoon heads 8 of different sizes for easy replacement. The lower recess of the spoon head 8 can also have several through holes to form a strainer, used to scoop up particles soaked in liquid while filtering out the liquid. The lower recess of the spoon head 8 can also have several grooves to form a fork-like spoon, used to pick up large, lumpy items.

[0069] When the retrieving device is a combination of a long rod 2 and a brush head, the bottle body 6 is suitable for holding liquid substances. The storage method is the same as described above, but the principle is slightly different. When the brush head comes into contact with the liquid inside the bottle, the buoyancy generated by the sealed cavity in the brush head is greater than the weight of the entire retrieving device. Furthermore, because the middle end of the retrieving device is fitted with the through hole in the lower half of the cap 7, the buoyancy of the liquid pushes the middle end of the retrieving device into the cavity of the cap. Only the brush bristles 10 remain in contact with the liquid, and the middle end of the retrieving device always floats above the liquid surface. Alternatively, a float, such as a miniature lifebuoy, can be installed inside the bottle, floating on the liquid surface. The float, in contact with the lower end of the retrieving device, can also lift the middle end of the retrieving device above the liquid surface. The bottle cap and bottle opening close easily, and the sealing ring 5 seals tightly against the bottle opening. When retrieving liquid substances from the bottle, there is no need to press the diaphragm 3; the depth at which the retrieving device floats in the liquid remains constant, ensuring that the brush head picks up the same amount of liquid each time. Whether storing or retrieving items, the middle of the retrieval device remains uncontaminated with liquid, reducing contamination of the bottle opening and cap, ensuring hygiene and preventing waste. During application, press the diaphragm 3; the contact point of the bow plate 4 locks the retrieval device, allowing the brush bristles to contact the object being brushed. Alternatively, without pressing the diaphragm 3, the middle of the retrieval device moves up and down within the through-hole of the lower cap 7 to maintain even brush pressure when the brush bristles are in contact with the varying surfaces of the object. Alternatively, the brush head can be removed from the cavity; regardless of the liquid level, the brush head can reach the bottom of the bottle to pick up the liquid, making it convenient to use.

[0070] When the retrieval device consists of a long rod 2 and a honey-collecting stick 11, the bottle body 6 is suitable for holding semi-fluid substances. Storage is performed using the same principle and method as the combination of the long rod 2 and the brush head. When retrieval the semi-fluid substance inside the bottle, the semi-fluid is usually viscous and has high buoyancy, so the portion of the honey-collecting stick 11 submerged in the semi-fluid substance during storage is small. When a larger amount needs to be retrieved, hold the handle of the cap with one hand, separating the cap from the bottle opening. Do not press the diaphragm 3 initially; wait for the retrieval device to slide down to the appropriate position, then press the diaphragm 3, locking the retrieval device at the contact point of the arch plate 4. Then insert the ball of the honey-collecting stick 11 into the semi-fluid substance inside the bottle to the appropriate depth. The honey-collecting stick 11 picks up a certain amount of semi-fluid substance and is then removed from the bottle.

[0071] Example 2: As Figure 9-12 As shown, a combined bottle cap and a condiment bottle having the bottle cap are disclosed. The bottle cap includes an upper half cap 1, a lower half cap 7, a diaphragm 3, a sealing ring 5, a picking device, and a locking device. The bottle cap and the bottle body 6 together form a condiment bottle.

[0072] The specific features are: the upper half cover 1 and the lower half cover 7 are connected by snaps to form the cover body. Figure 12As shown, the upper surface of the lower cover 7 has two upward-facing protrusions. Each of these protrusions has a through hole on its sidewall. These through holes hook onto a small protrusion on the inner wall of the handle portion of the upper cover 1, forming a snap-fit ​​connection. The diaphragm 3 has a sandwich structure and blocks the through hole in the handle portion of the upper cover 1. A groove is located to the left of the middle through hole in the lower cover 7.

[0073] The object-retrieving device includes a long rod 2 and a spoon head 8. The connection between the two is concave-convex and convex, not planar. The internal structural features of the two are shown in the cross-sectional view of Embodiment 1. One has a blind hole and the other has a short pin. The blind hole and the short pin are interference fit. The blind hole can be a round hole and the cross-section of the short pin can be circular.

[0074] The locking device is a pry bar 12. The upper right side of the pry bar 12 has a pressing part, which is inserted into the interlayer of the diaphragm 3 and fixedly connected to the diaphragm 3. Alternatively, the interlayer of the diaphragm 3 can be removed, and the pry bar 12 and the diaphragm 3 can be bonded together. The pry bar 12 has a through hole in the middle, through which a long rod 2 is inserted, with a gap between the pry bar 12 and the long rod 2. This gap allows the upper end of the retrieval device to move up and down within the cavity of the cover without obstruction. The left side of the middle end of the pry bar 12 contacts the inner wall of the cover, and the left side of the lower end of the pry bar 12 has a contact point located in a groove on the left side of the through hole in the lower half of the cover 7. This contact point corresponds to the retrieval device, and the two are fitted together with a clearance.

[0075] All other technical features of Example 2 are the same as those of Example 1.

[0076] The locking device works as follows: the middle part of the retrieval device is located inside the through hole of the lower half cover 7, regardless of its position. Pressing the diaphragm 3 deforms it, pushing the pressing part of the pry bar 12 to the left. Since the left side of the middle part of the pry bar 12 contacts the inner wall of the cover, a fulcrum is formed. Utilizing the lever principle, the lower contact point of the pry bar 12 tilts to the right until it contacts the left side wall of the retrieval device, locking the retrieval device. The contact point may have a concave-convex structure to improve the locking ability. Releasing the diaphragm 3 with a finger causes it to return to its original shape, moving the pressing part of the pry bar 12 back to its original position; alternatively, a spring can be added to replace the diaphragm 3, causing the pry bar 12 to reset. Figure 9 As shown, the contact point of the pry bar 12 is in the state of releasing the object-retrieving device. (or) Figure 9 The left middle of the pry bar 12 moves upward and contacts the inner wall of the upper end of the handle cavity, meaning the fulcrum position moves upward and is higher than the right handle of the pry bar 12. The contact point of the pry bar 12 and the groove on the left side of the through hole in the lower half cover 7 both rotate 180 degrees along the axis and move to the right side of the through hole in the lower half cover 7. A gap remains on the left side of the lower end of the pry bar 12; everything else remains unchanged. Pressing the diaphragm 3 locks the right contact point of the pry bar 12 onto the right side of the retrieval device. Releasing the diaphragm 3 causes the pry bar 12 to reset.

[0077] The usage method of this embodiment is the same as that of Embodiment 1.

[0078] Example 3: As Figure 13-15As shown, a combined bottle cap and a condiment bottle having the bottle cap are disclosed. The bottle cap includes an upper half cap 1, a lower half cap 7, a diaphragm 3, a sealing ring 5, a picking device, and a locking device. The bottle cap and the bottle body 6 together form a condiment bottle.

[0079] The specific features are as follows: the upper half cover 1 and the lower half cover 7 are connected by adhesive or welding, or by screws. Welding includes ultrasonic welding to form the cover body. A positioning pin or a concave-convex positioning structure can be set at the joint of the two to facilitate assembly. The upper and lower edges of the through hole in the middle of the lower half cover 7 are provided with bosses, and a groove is provided on the left side of the boss above the through hole.

[0080] The described object-retrieving device includes a long rod 2, a brush head, and a metal rod 13. The brush head includes a short handle 9 and bristles 14. The long rod 2 and the brush head are connected by the metal rod 13. The short handle 9 is made of a hard material and has a cavity in the middle. A through hole is located at the top of the short handle 9, connecting to the cavity. This hole is press-fitted with one end of the metal rod 13, which then blocks the hole, making the cavity of the short handle 9 a sealed cavity. The other end of the metal rod 13 is connected to a blind hole at the bottom of the long rod 2, also press-fitted. The long rod 2 may have a through hole in the middle to reduce weight. The metal rod 13 is made of metal, such as stainless steel, for a more secure connection. Other object-retrieving devices in Embodiment 1 can also use the metal rod 13 for connection. The bristles 14 are made of a flexible, soft material, such as silicone. Several bristles 14 are located at the bottom of the short handle 9. The lower end of the retrieval device includes the bristles 14 and the lower part of the short brush handle 9, and is always located outside the cover. The middle part of the retrieval device includes the slender part of the long rod 2 excluding the long rod cap, and the upper part of the short brush handle 9. The middle part of the retrieval device is fitted with the through hole of the lower half cover 7 with a clearance, and can move up and down within this hole.

[0081] The locking device is a pry bar 12. The upper right end of the pry bar 12 has a pressing part corresponding to the diaphragm 3, with the two either in contact or with a gap. A through hole is provided in the middle of the pry bar 12, and a lifting device is located in the middle of this through hole. A gap is left between the two, allowing the upper end of the lifting device to move up and down unimpeded within the cavity of the cover. The left side of the middle end of the pry bar 12 is hinged to the cover. Figure 15 As shown, the lower cover 7 has two protrusions on its left side, and each protrusion has a semi-circular groove at its top. The upper cover 1 also has two protrusions on its left side, and each of these protrusions has a semi-circular groove at its bottom. Figure 14 The pry bar 12 shown has a round shaft on the left side of its middle end. This round shaft is engaged in the round hole formed by the semi-circular grooves of the upper half cover 1 and the lower half cover 7, which together form a hinge. The lower left end of the pry bar 12 has a contact point, which is located in the groove along the edge of the through hole of the lower half cover 7 and is in clearance fit with the object retrieval device.

[0082] The remaining technical features of Example 3 are the same as those of Example 1.

[0083] The locking device works as follows: the middle part of the retrieval device is inside the through hole of the lower half cover 7, regardless of its position. Because the left side of the middle part of the pry bar 12 is hinged to the cover, pressing the diaphragm 3 deforms the diaphragm 3, pushing the pressing part of the pry bar 12 to rotate counterclockwise around the axis. The lower contact point of the pry bar 12 will tilt to the right until it contacts the left side wall of the retrieval device, thus locking the retrieval device. Figure 13 As shown, when the finger relaxes the diaphragm 3, the diaphragm 3 returns to its original shape. Under the action of gravity, the pry bar 12 rotates clockwise around the axis, and the contact point of the pry bar 12 releases the object-retrieving device. To make the pry bar 12 move more sensitively, a spring can also be added, or the pressing part of the pry bar 12 can be connected to the diaphragm 3.

[0084] The usage method of this embodiment is the same as that of Embodiment 1.

[0085] Example 4: Figure 16-18 As shown, a combined bottle cap and a condiment bottle having the bottle cap are disclosed. The bottle cap includes an upper half cap 1, a lower half cap 7, a diaphragm 3, a sealing ring 5, a picking device, and a locking device. The bottle cap and the bottle body 6 together form a condiment bottle.

[0086] The specific features are as follows: the outer side of a raised ring on the lower end face of the upper half-cap 1 contacts the sealing ring 5, and the inner side of this raised ring engages with a raised ring on the upper end face of the lower half-cap 7 to form the cap body. The upper and lower edges of the through hole in the middle of the lower half-cap 7 are provided with raised rings, and a groove is provided on the right side of the upper raised ring. The lower diameter of the upper half-cap 1 is larger than the inner diameter of the bottle mouth of the bottle body 6 and contacts the bottle mouth.

[0087] The described object-retrieving device includes a long rod 2, a honey-collecting stick head 11, and a metal tube 15. The long rod 2 and the honey-collecting stick head 11 are connected by the metal tube 15, meaning that both the bottom end of the long rod 2 and the top end of the honey-collecting stick head 11 are provided with short pins, which are inserted into one end of the metal tube 15 with an interference fit. The metal tube 15 makes the connection more secure. Other object-retrieving devices in Embodiment 1 can also be connected using the metal tube 15.

[0088] The locking device includes a slider 16 and a spring 17. The slider 16 has an upward-facing boss on its right side, which is the pressing part, corresponding to the diaphragm 3. Figure 17 As shown, the slider 16 has a recess in the middle (the through hole in the middle of the pry bar 12 mentioned above can also be replaced by a recess). The object-retrieving device is located in the middle of this recess, and there is a gap between the two to facilitate the upper end of the object-retrieving device to move up and down in the cavity of the cover. Figure 16As shown, the lower right side of the slider 16 has a contact point, which is clearance-fitted with the side wall of the long rod 2 or the metal tube 15. Alternatively, the contact point has a groove that can hold the long rod cap, similar to the contact point of the bow piece 4 in embodiment 1. Alternatively, the side wall of the long rod 2 can be slotted or perforated, and the contact point of the slider 16 can be locked into this slot or hole. The slider 16 is set in the slider groove inside the cover cavity and can only slide left and right within the slider groove. A small cylinder is provided on the left side of the slider 16, one end of the spring 17 is sleeved on the small cylinder of the slider 16, and the other end of the spring 17 contacts the inner wall of the slider groove inside the cover cavity.

[0089] The remaining technical features of Example 4 are the same as those of Example 1.

[0090] Working principle of the locking device: The middle part of the retrieval device is located in the through hole of the lower half cover 7, regardless of its position. Pressing the diaphragm 3 deforms it, squeezing the pressing part of the slider 16, causing the slider 16 to move to the left in the slider groove. The slider 16 compresses the spring 17, which contracts and stores energy until the contact point on the lower right side of the slider 16 contacts and locks the retrieval device. Releasing the finger from the diaphragm 3 causes it to return to its original shape. The spring 17 pushes the slider 16, moving it to the left in the slider groove of the cover, quickly resetting it. The contact point of the slider 16 then releases the right side of the retrieval device. Alternatively, the spring 17 can be removed, and the pressing part of the slider 16 can be connected to the diaphragm 3. The slider 16 relies on the elasticity of the diaphragm 3 to reset, but its effectiveness and service life are not as good as the solution using the spring 17.

[0091] The usage method in this embodiment is the same as that in Embodiment 1.

[0092] Example 5: Figure 19-21 As shown, a combined bottle cap and a condiment bottle having the bottle cap are disclosed. The bottle cap includes an upper half cap 1, a lower half cap 7, a diaphragm 3, a sealing ring 5, a picking device, and a locking device. The bottle cap and the bottle body 6 together form a condiment bottle.

[0093] Specific features include: a raised edge along the lower edge of the central through-hole in the lower cap 7; a recessed area at the top of the handle of the upper cap 1 for easy label application; and a roughly "n"-shaped cross-section for the sealing ring 5, with an outer diameter significantly larger than the cap body diameter, which engages with the outer wall of the cap, significantly increasing the cap opening diameter. The sealing ring 5 is made of a material of a certain hardness; or the part in contact with the inner wall of the bottle opening is made of a flexible, soft material, while the remaining parts are made of a hard material. The sealing ring 5 can also be transparent. For bottles 6 with different opening diameters within a certain range, simply replacing the sealing ring 5 with one of the corresponding diameter will achieve a seal. The diameter and material of the sealing ring 5 in Example 1 can also be implemented in the same way.

[0094] The described object-retrieving device includes a long rod 2 and a spoon head 8. The long rod 2 has a long rod cap at its top, and the side wall of the long rod cap has a bevel. The bottom end of the long rod 2 has a short pin structure. The lower end of the spoon head 8 has a sealed cavity, and the top end of the spoon head 8 has a blind hole. The spoon head 8 and the long rod 2 are connected by an interference fit between the short pin and the blind hole. Alternatively, the cavity of the spoon head 8 communicates with the hole at the top end of the spoon head 8, and the short pin of the long rod 2 seals the hole at the top end of the spoon head 8, making the cavity of the spoon head 8 a sealed cavity.

[0095] The locking device includes a slider 16 and a spring 17. The slider 16 has an upward-pressing portion on its right side, corresponding to the diaphragm 3. The slider 16 has a through hole in the middle (in Embodiment 4, the recessed portion in the middle of the slider 16 can also be replaced by a through hole). A lifting device is located in the middle of this through hole, with a gap between them. The lower end of the inner wall of the through hole in the slider 16 has a slope, corresponding to the slope of the long rod cap, with the slope angles being the same. The right side of the through hole in the slider 16, including the sloped portion on the right side of the through hole, is the contact point, which is in clearance fit with the lifting device. The spring 17 is a sheet-like elongated strip, located on the left side of the slider 16.

[0096] All other technical features of Example 5 are the same as those of Example 4.

[0097] Working principle of the locking device: The long rod 2 moves downwards within the through hole of the lower half cover 7 until the long rod cap contacts the upper end of the through hole of the lower half cover 7. Pressing the diaphragm 3 deforms the diaphragm 3, squeezing the pressing part of the slider 16, causing the slider 16 to move to the left in the slider groove. The slider 16 squeezes the spring 17, which deforms and stores energy until the contact point on one side of the slider 16 contacts the long rod 2, and the inclined surface on the right side of the through hole of the slider 16 contacts the inclined surface of the long rod cap. The inclined surfaces of the two engage to lock the lifting device, preventing it from shaking. Alternatively, both inclined surfaces can be removed, and the long rod cap can be clamped by the engagement between the lower end face of the through hole of the slider 16 and the upper end face of the through hole of the lower half cover 7. However, the machining accuracy determines the degree of shaking of the lifting device in the locked state. When the long rod cap does not contact the upper end of the through hole of the lower half cover 7, the slider 16 moves to the left, and the contact point on the right side of the through hole of the slider 16 contacts the side wall of the long rod 2, locking the long rod 2. When the diaphragm 3 is relaxed, it returns to its original shape. The spring 17 pushes the slider 16 to move to the right, and the slider 16 releases the object-retrieving device.

[0098] The usage method of this embodiment is the same as that of embodiment 1. In addition to scooping particulate matter, the spoon head 8 of this embodiment can also scoop liquid and semi-fluid substances. The spoon head 8 with the cavity can also be suspended in liquid or semi-fluid substances.

[0099] Example 6: As Figure 22-23 As shown, a combined bottle cap and a condiment bottle having the bottle cap are disclosed. The bottle cap includes an upper half cap 1, a lower half cap 7, a diaphragm 3, a sealing ring 5, a picking device, and a locking device. The bottle cap and the bottle body 6 together form a condiment bottle.

[0100] The specific features are as follows: the upper half-cap 1 has a through hole and a recess on the side wall of the handle portion, the through hole and the recess are connected, and the diaphragm 3 is bonded to this recess, which also seals the through hole and forms a cavity. The upper half-cap 1 and the lower half-cap 7 are snapped together to form a cap body. The groove on the side wall of the cap body has an "L"-shaped sealing ring 5. The diameter of the lower end of the upper half-cap 1 is larger than the inner diameter of the bottle mouth of the bottle body 6, and it contacts the bottle mouth.

[0101] The described object-retrieving device includes a screw 18 and a spoon 19. The upper end of the spoon 19 has a long handle, and the middle of the object-retrieving device is the handle of the spoon 19, which moves up and down within the through-hole of the lower half-cover 7, with a clearance fit between the two. The cross-section of the handle of the spoon 19 is "D"-shaped, but it can also be square, elliptical, or polygonal. The cross-sectional shape of the through-hole of the lower half-cover 7 is the same as that of the handle of the spoon 19. The top of the spoon 19 has a screw 18, the diameter of the upper head of the screw 18 being larger than the diameter of the through-hole of the lower half-cover 7, serving the same function as the long rod cap mentioned earlier. Alternatively, a pin or retaining spring can be used instead of the screw 18; however, the screw 18 can be a large flat-head screw from the market, with a head thickness between 0.5 and 1.2 mm. Compared to pins and retaining springs, using a screw 18 has less impact on the length of the object-retrieving device. The upper end of the object-retrieving device is the head of the screw 18, which is always located within the cavity of the cover. The lower end of the object-retrieving device is the lower recess of the spoon 19, which is always located outside the cover. In Example 1, the upper end of the spoon head 8 is lengthened to form the spoon 19. The lower end of the spoon 19 may also have one to three grooves to form a fork spoon or dinner fork. The lower end of the spoon 19 may also have several through holes to form a slotted spoon.

[0102] The locking device includes a hydraulic pipe 20 and hydraulic oil. The hydraulic pipe 20 is a tubular structure with a closed lower end; its upper end connects to the through-hole of the handle, forming a closed cavity filled with hydraulic oil. The lower end of the hydraulic pipe 20 is inserted into a groove in the side wall of the through-hole of the lower half-cover 7. A contact point is located on the left side of the lower end of the hydraulic pipe 20, corresponding to the lifting device, and the two are fitted with a clearance. The hydraulic pipe 20 has a certain degree of elasticity, especially at the contact point.

[0103] The remaining technical features of Example 6 are the same as those of Example 1.

[0104] Working principle of the locking device: The handle of the spoon 19 is located within the through hole of the lower half cover 7, regardless of its position. Pressing the diaphragm 3 deforms it, reducing the volume of the cavity between the diaphragm 3 and the recess of the upper half cover 1. This forces some hydraulic oil into the hydraulic pipe 20. The upper end of the hydraulic pipe 20 deforms less, and the contact point at its lower end, under the pressure of the hydraulic oil, bulges outward, clamping the handle of the spoon 19. Releasing the diaphragm 3 restores its original shape, allowing the hydraulic oil in the hydraulic pipe 20 to flow back, the contact point returns to its original shape, and the lifting device is released.

[0105] The usage method of this embodiment is the same as that of embodiment 1.

[0106] Example 7: As Figure 24-25 As shown, a combined bottle cap and a condiment bottle having the bottle cap are disclosed. The bottle cap includes an upper half cap 1, a lower half cap 7, a diaphragm 3, a sealing ring 5, a picking device, and a locking device. The bottle cap, the perforated cap 22, and the bottle body 6 constitute the condiment bottle.

[0107] The specific features are as follows: the upper half of the cover 1 is the handle, and the middle cavity of the handle connects to the bottom of the upper half of the cover 1, with a through hole on its side wall. The diaphragm 3 is made of an elastic flexible material, such as silicone, and is a tubular structure that runs vertically through the upper half of the cover. The diaphragm 3 is fitted tightly onto the outer wall of the upper half of the cover 1, sealing the through hole on its side wall. (The diaphragm 3 in the embodiments described above can all adopt this tubular structure and be set on the outer wall of the handle of the upper half of the cover 1.) The upper half of the cover 1 and the lower half of the cover 7 are connected by welding, bonding, snap-fitting, or screws to form the cover body. The lower half of the cover 7 has a sealing ring 5 along its edge, and the sealing ring 5 has a "C" shaped cross-section. The perforated cover 22 has a through hole in the middle, and a combined bottle cap is installed in this hole. The sealing ring 5 fits and seals with the through hole of the perforated cover 22. The lower end of the perforated cover 22 is threaded to the bottle body 6. The perforated cover 22 is designed to enlarge the diameter of the bottle mouth and reduce the diameter of the cover body, making it convenient for storage and retrieval; and the perforated cover 22 is precisely sized to improve the sealing performance of the sealing ring 5. The lower half of the cover 7 has protrusions along both the upper and lower edges of the through hole, and a groove on the right side of the upper protrusion. A label can be attached to the top of the handle of the upper half of the cover 1. The sealing ring 5 and the diaphragm 3 can also be combined into one integral part and set on the outer wall of the cover. Alternatively, the lower end of the tubular diaphragm 3 can be understood as extending to the installation position of the sealing ring 5, with the lower end of the diaphragm 3 wrapping around the edge of the cover to achieve the function of the sealing ring 5, which can then be removed.

[0108] The described object-retrieving device includes a screw 18 and a brush. The brush includes a long handle 21 and a bristle body 10. The upper end of the long handle 21 has a long stem with an elliptical cross-section. This stem is the middle of the object-retrieving device and moves up and down within the through hole of the lower half-cover 7, with a clearance fit between the two. The top of the long handle 21 has a screw 18, the head of which functions the same as the long rod cap and is always located within the cavity of the cover. The lower end of the long handle 21 has a larger cross-section and both it and the upper end of the bristle body 10 have cavities, which together form a sealed cavity. The lower end of the bristle body 10 has several long, thin bristles. The lower end of the object-retrieving device is the section where the bristle body 10 and the lower end of the long handle 21 change diameter, and it is always located outside the cover. The short handle 9 of the brush head mentioned above is lengthened to form the brush.

[0109] The locking device is a bow plate 4. The middle right side of the bow plate 4 corresponds to the diaphragm 3. The lower right side of the bow plate 4 is provided with a contact point. The bottom end of the contact point is set in the groove on the right side of the through hole of the lower half cover 7. The contact point corresponds to the side wall of the object retrieval device, and the two are fitted with a gap.

[0110] The remaining technical features of Example 7 are the same as those of Example 1.

[0111] The locking device works as follows: The long brush handle 21 moves downwards within the through hole of the lower half cover 7 until the head of the screw 18 contacts the upper end of the through hole of the lower half cover 7. Pressing the diaphragm 3 at the position corresponding to the through hole of the upper half cover 1 deforms the diaphragm 3, compressing the bow plate 4. The lower contact point of the bow plate 4 contacts the head of the screw 18, locking the retrieval device. Alternatively, even if the head of the screw 18 does not contact the upper end of the through hole of the lower half cover 7, the contact point of the bow plate 4 contacts the side wall of the long brush handle 21, which also locks the retrieval device.

[0112] In this embodiment, the storage method involves unscrewing the cap 22; the bottle cap and cap 22 do not need to be separated, and items can be directly inserted into the bottle opening. The diameter of the bottle opening is larger than the through hole of the cap 22 for ease of operation. Then, without pressing the diaphragm 3 corresponding to the through hole on the side wall of the upper half of the cap 1, the bottle body 6 and cap 22 can be closed. In this embodiment, the method for retrieving items involves first squeezing the handle of the cap body to separate the bottle cap from the cap 22; the rest is the same as the method for retrieving items in Embodiment 1.

[0113] Example 8: As Figure 26-27 As shown, a combined bottle cap and a condiment bottle having the bottle cap are disclosed. The bottle cap includes an upper half cap 1, a lower half cap 7, a diaphragm 3, a sealing ring 5, a picking device, and a locking device. The bottle cap, the perforated cap 22, and the bottle body 6 constitute the condiment bottle.

[0114] The specific features are as follows: The upper half-cap 1 has a through hole at the top of its handle. The diaphragm 3 is a tubular structure, with its top not through. The diaphragm 3 is fitted tightly onto the outer wall of the upper half-cap 1 handle, sealing its top through hole. (The diaphragm 3 in the embodiments described above can all adopt this tubular structure and be set on the outer wall of the upper half-cap 1 handle. In embodiment 6, when the diaphragm 3 adopts this tubular structure, a cavity filled with hydraulic oil can be provided at the top of the upper half-cap 1 handle, and the through hole at the top of the handle is connected to a hydraulic pipe 20.) The upper edge of the through hole in the middle of the lower half-cap 7 has a slope between 30 and 60 degrees. A boss is provided on the lower edge of this through hole, and a retrieval device is provided in the through hole. The upper half-cap 1 and the lower half-cap 7 are threaded together to form a cap body, and a sealing ring 5 is provided on the outer wall of the cap body. The upper half-cap 1 and the lower half-cap 7 can also be combined into one, i.e., the cap body is a single integral part. The lower end of the cap 22 is inserted into the inner wall of the bottle mouth of the bottle body 6, and a sealing ring can also be provided between the two. The through-hole of the cap 22 houses a modular bottle cap. The through-hole of the cap 22 is offset to the right, not on the axis of the bottle body 6, and is made of transparent material, making it easier to retrieve items through the through-hole. The bottle body 6 is bowl-shaped, with a significantly different diameter from the through-hole diameter of the cap 22, making it easier to open the cap 22 to insert items into the bottle body 6 and to clean the inner wall of the bottle body 6. The upper surface of the cap 22 may also have multiple through-holes, each housing a modular bottle cap. The bottle body 6 may also have multiple storage compartments, each with independent storage, provided the diameter of the bottle body 6 is large enough.

[0115] The described object-retrieving device includes a screw 18 and a honey-retrieving rod 23. The upper end of the honey-retrieving rod 23 has a long handle, which is the middle part of the object-retrieving device. The handle moves up and down within the through-hole of the lower half-cover 7, with a clearance fit between the two. The top of the honey-retrieving rod 23 has a screw 18, the diameter of which is larger than the diameter of the through-hole in the lower half-cover 7. The upper end of the object-retrieving device is the head of the screw 18, which is always located within the cavity of the cover. The lower end of the object-retrieving device is the lower spherical part of the honey-retrieving rod 23, which is always located outside the cover. The cavity at the lower end of the honey-retrieving rod 23 can communicate with the threaded hole at the top of the honey-retrieving rod 23; the extended handle of the aforementioned honey-retrieving rod head 11 constitutes the honey-retrieving rod 23.

[0116] The locking device is a bow plate 4, which is U-shaped. The upper end of the bow plate 4 passes through the top hole of the handle of the upper half cover 1. The top of the bow plate 4 corresponds to the diaphragm 3. The lower end of the bow plate 4 is provided with two contact points. Both contact points are provided with inclined surfaces. The inclined surfaces of the two contact points are in contact with the inclined surfaces of the lower half cover 7. The inclinations of the two are the same. Both contact points are in clearance fit with the middle side wall of the object retrieval device.

[0117] The remaining technical features of Example 8 are the same as those of Example 1.

[0118] The locking device works as follows: The handle of the honey-collecting stick 23 moves downward within the through hole of the lower half-cover 7 until it reaches the desired position. Pressing down on the top of the diaphragm 3 with a finger pushes the bow plate 4 downward. Since the two contact points at the lower end of the bow plate 4 are in contact with the lower half-cover 7 at an angle, pushing the two contact points of the bow plate 4 moves towards the side wall of the honey-collecting stick 23, locking the honey-collecting stick 23. Releasing the pressure on the diaphragm 3 causes its top to return to its original position under its own elasticity, and the bow plate 4 also returns to its original position under its own elasticity, releasing the contact points and disengaging the honey-collecting device.

[0119] The method of use in this embodiment differs slightly from that in Embodiment 1, namely, the diaphragm 3 at the top of the handle is pressed or released with the finger. Considering the gesture of pinching the bottle cap, its effectiveness is not as good as that of the embodiment described above.

[0120] Example 9: As Figures 28-30 As shown, a combined bottle cap and a condiment bottle having the bottle cap are disclosed. The bottle cap includes an upper half cap 1, a lower half cap 7, a diaphragm 3, a sealing ring 5, a picking device, and a locking device. The bottle cap and the bottle body 6 together form a condiment bottle.

[0121] The specific features are as follows: The lower end face of the upper cap 1 has two rings of thin-walled protrusions to reduce injection molding shrinkage marks on the surface of the upper cap 1 and to clamp the sealing ring 5; these two rings of protrusions may also have reinforcing ribs to improve structural strength. The protrusions on the lower end face of the upper cap 1 and the protrusions on the upper end face of the lower cap 7 are snap-fitted together to form the cap body. Alternatively, they can be joined by bonding, welding, or screws to form the cap body. The two rings of thin-walled protrusions on the upper cap 1 have the same downward protrusion height, forming a gap with the lower cap 7, in which the sealing ring 5 is placed. A step or groove is provided at the junction of the upper cap 1 and the diaphragm 3 to ensure a more secure connection.

[0122] The aforementioned object-grabbing device is a spoon 19, which has a long handle at its upper end and a long rod cap at its top. Figure 29 As shown, the long-handled cap has protruding side walls and a slot at the top, with the slot opening in the shape of an arrow. To achieve the desired deformation effect and extend its service life, the protrusions on the side walls of the long-handled cap are pressed towards the center, causing the cap to elastically deform and the gap at the top of the slot to decrease. (This long-handled cap can also be understood as the male buckle of a detachable snap-fit.) Alternatively, the long-handled cap may be made of a flexible, soft material, with no slot at the top, shaped like the screw 18 described above, and fixedly connected to the top of the handle of the spoon 19. Figure 28 As shown, the right side of the long-handled cap has a step that engages with the locking device. The height of this step is close to or equal to the depth of the groove at the top of the long-handled cap. The spoon 19, excluding the long handle portion of the long-handled cap, fits with the through hole of the lower half-cap 7 with a clearance. The lower end of the spoon 19 has a recess and is located outside the cap. Both the brush and the honey-collecting stick 23 in the previous embodiments can have long-handled caps with grooved tops, or the long-handled caps can be made of a flexible, soft material.

[0123] The locking device includes a slider 16 and a spring 17. The slider 16 has a through hole in the middle, and reinforcing ribs are provided around the through hole to connect the upper pressing part and the lower contact point of the slider 16 in order to enhance the structural strength of the slider 16.

[0124] The remaining technical features of Example 9 are the same as those of Example 4.

[0125] Working principle of the locking device: When the handle of the spoon 19 is inside the through hole of the lower half cover 7, it can slide up and down to any position. Pressing the diaphragm 3 deforms the diaphragm 3, squeezing the pressing part of the slider 16, causing the slider 16 to move to the left in the slider groove. The slider 16 squeezes the spring 17, which contracts and stores energy until the contact point at the lower end of the slider 16 contacts and locks the spoon 19, at which point the spoon 19 stops moving. When the spoon 19 slides freely downwards until the protrusion on the side wall of the long rod cap contacts and locks with the boss of the through hole of the lower half cover 7, the spoon 19 does not separate from the cover because the weight of the lifting device cannot induce elastic deformation of the long rod cap. The slider 16 moves to the left, and its contact point slides into the step position on the right side of the long rod cap of the spoon 19, further locking the spoon 19 and preventing it from moving upwards. (Alternatively, the right-side step can be removed from the long rod cap, and the top flat surface or top groove of the long rod cap can contact the slider 16 to lock the spoon 19.) Releasing the diaphragm 3 causes the slider 16 to move to the right, thus releasing the spoon 19. Symmetrical steps can also be provided on both sides of the long rod cap, allowing the long handle of the spoon 19 to rotate 180 degrees along its axis and insert into the cover. The slider 16 can then contact and lock with either side of the step on the long rod cap. If the handle of the spoon 19 is inserted into the through hole of the lower half of the cover 7, the two will be in an interference fit, and the locking device will not function.

[0126] The usage method of this embodiment differs slightly from that of Embodiment 1. To replace the retrieval device, the handle of the spoon 19 is directly inserted into or pulled out of the through hole of the lower cover 7. The long handle of the spoon 19 is squeezed by the side wall of the through hole of the lower cover 7, causing elastic deformation, which allows the spoon 19 to be installed or removed. Replacing the retrieval device is convenient and quick. The rest of the usage method is the same as that of Embodiment 1.

[0127] Example 10: As Figures 31-32 As shown, a combined bottle cap and a condiment bottle having the bottle cap are disclosed. The bottle cap includes an upper half cap 1, a lower half cap 7, a diaphragm 3, a sealing ring 5, a picking device, and a locking device. The bottle cap and the bottle body 6 together form a condiment bottle.

[0128] The specific features are: the lower end face of the upper cap 1 has two rings of thin-walled protrusions, namely protrusion 101 and protrusion 102. The downward protrusion height of protrusion 101 is higher than that of protrusion 102, and the height difference between the two is equal to or slightly greater than the height of the sealing ring 5. The sealing ring 5 is inserted into the gap between protrusion 102 and the lower cap 7. The inner wall of the sealing ring 5 is in close contact with the outer wall of protrusion 101, and the outer wall of the sealing ring 5 is in close contact with the bottle body 6. (Alternatively, the outer wall where protrusion 101 contacts the sealing ring 5 may have a step, or an additional ring of protrusion 102 may be added to further secure the sealing ring 5.) Besides Figure 31 The lower half cover 7 shown has no boss on the right side of the through hole in the middle, but the remaining holes have bosses on both the upper and lower edges, and the upper surface of the upward bosses on the edge of the holes has a step.

[0129] The aforementioned object-retrieving device is a brush, which includes a long handle 21 and a bristle body 10. (For ease of observation, the brush is shown separated from the cover in the figure.) The upper end of the brush has a long handle 21, and the upper end of the long handle 21 has a long stem, with a long cap at the top. Figure 31 As shown, the width of the long brush handle 21 is slightly smaller than the width of the through hole in the middle of the lower half of the cap 7. The long handle cap has symmetrical grooves on both sides, and the lower ends of these two grooves are close to or equal to the width of the through hole in the middle of the cap 7. Figure 32 The depth of the groove in the middle of the long rod cap is shown. Figure 32 As shown, the long handle cap has protrusions on both sides, and its width is slightly larger than the width of the through hole in the middle of the lower half of the cover 7. The flat part of the lower section of the long brush handle 21 is fastened to the concave part at the top of the brush body 10, and the lower end of the brush body 10 is provided with several thin and long bristles.

[0130] The locking device includes a slider 16 and a spring 17. The slider 16 has a through hole in the middle, and a boss along the edge of this through hole. The upward-facing boss forms a pressing part, and the downward-facing boss forms a contact point. The inner walls of the upward and downward-facing bosses along the edge of the through hole of the slider 16 are on the same arc surface or plane.

[0131] The remaining technical features of Example 10 are the same as those of Example 9.

[0132] Working principle of the locking device: The upper end of the long brush handle 21 is inserted into the through hole of the lower half cover 7. The protrusions on both sides of the long rod cap pass through this through hole. The handle of the long brush handle 21 can slide up and down to any position within the through hole of the lower half cover 7. Pressing the diaphragm 3 deforms it, squeezing the pressing part of the slider 16, causing the slider 16 to move to the left in the slider groove. The slider 16 compresses the spring 17, which contracts and stores energy until the contact point at the lower end of the slider 16 contacts and locks the picking device. When the long brush handle 21 slides down freely due to gravity, it continues until the protrusion on the side wall of the long rod cap contacts and locks against the boss of the through hole of the lower half cover 7, preventing the brush from separating from the cover. The slider 16 moves to the left, and its contact point slides into the groove on the right side of the long rod cap of the long brush handle 21, further locking the long brush handle 21 and preventing it from moving upward. The upper end of the slider 16 contact point has a bevel or arc surface to prevent accidental operation. When the brush is locked and forcefully separated from the cover, the bevel at the upper end of the contact point contacts the groove of the long rod cap and easily detaches without damaging the long rod cap. Alternatively, the upper part of the long rod cap groove that contacts the contact point has a bevel or arc surface to achieve the same effect. The lower part of the long rod cap groove that contacts the contact point is at a right angle for easy locking. The long brush handle 21 can rotate 180 degrees along its axis, and its long handle can also be inserted into the through hole of the lower half cover 7. The slider 16 contact point can contact and lock with the groove on either side of the long rod cap. Releasing the diaphragm 3 releases the brush from the slider 16.

[0133] The usage method of this embodiment differs slightly from that of Embodiment 1, namely, the object-retrieving device is replaced. The replacement of the object-retrieving device is the same as in Embodiment 9, while the rest of the usage method is the same as in Embodiment 1.
