Description

Technical Field

[0001] This invention relates to handles for containers, particularly handles for lightweight household heating containers. Technical Background

[0002] Existing containers, especially lightweight household containers and heating containers, are often held by one hand, which makes it easy for the container wall fixing holes, rivets, etc. to be pried and worn, and thus easy to slip off the handle.

[0003] With existing container lids, people inevitably hold them sideways, which can easily cause the nuts and threads in the handle, as well as the bottom surface of the lid handle corresponding to the handle base, to be pried or worn, making it easy for the handle to come off. People inevitably grab the handle to turn the lid, or after the lid has turned, they inevitably grab the handle to stop it from turning, causing rotational sliding between the handle base and the bottom surface of the handle, loosening the bolts, and thus loosening the handle.

[0004] The "Overflow-Proof Steamer" in Chinese Patent Publication No. CN223627334U is a multi-layer steamer that can hold relatively heavy items. The handle on the bottom pot has a relatively long end and two small rivets. However, this is to increase the strength of the handle and rivets when lifting the steamer by gripping the handle with both hands, making it suitable for holding relatively heavy items. It is not intended to prevent damage to the fixing holes and rivets on the bottom pot wall when lifting it by gripping the handle with one hand (the fact that the handle on the steaming rack, which is only used to hold relatively light items, has a relatively short end and only one rivet also proves this).

[0005] Some heating containers often exhibit the phenomenon of being able to be used normally but not being able to be filled with too much water. This is because the rivets that secure the handles on the heating container (pot) wall are easily pried loose and damaged, causing liquid leakage. As a result, the rivets for the handles have to be installed as high as possible on the pot wall. However, as long as the pot is not filled with too much liquid, even if liquid leaks from the rivets on the pot wall, it will not leak because the rivets are installed high up.

[0006] Handles on heating container lids are often made of bakelite or similar materials. These handles are typically secured by bolts passing through fixing holes in the lid and handle base, then screwing a nut into the bolt. This assembly, consisting of the lid, handle base, and handle connected by bolts, is prone to damage due to the nut's thread. This means that only a relatively small force can be used to tighten the bolts, making it difficult to maintain a stable connection between the lid and base (and between the lid and handle) over a long period.

[0007] To prevent the bakelite (nut) threads on the handle of the heating container lid from easily wearing out and stripping, some manufacturers "embed" metal nuts in the bakelite, using the metal threads of the nut instead of the bakelite threads. However, bakelite and metal are not the same material, and bakelite is softer while metal nuts are harder, so their ability to connect is weaker, and the nuts can easily be pried loose and fall off in the handle.

[0008] The handle on a pressure cooker lid is extremely large, consuming a lot of material and resulting in significant waste. This design primarily aims to allow for easy one-handed opening of the lid. Because the lid needs to withstand high pressure and is therefore quite heavy, a rubber sealing ring is encased in the sealing groove of the pressure cooker lid. This ring is located on the protruding edge of the pot opening, generating considerable friction on the lid. Furthermore, the lever arm of this friction is equal to the radius of the lid, resulting in a large torque. Therefore, even after the pressure cooker has released pressure, people with less strength, especially women and children, still find it difficult to open the lid with one hand due to their smaller wrist strength, resulting in a smaller force, lever arm, and torque required to turn the lid. Summary of the Invention

[0009] The present invention aims to overcome the above-mentioned defects and provide a handle for containers, especially lightweight household heating containers, that is simple in structure and durable.

[0010] 1. Lightweight container wall handle

[0011] For lightweight containers, including household heating containers such as steamers and stainless steel pots, people often unconsciously or consciously hold them by one handle for speed or convenience. When holding them with one hand, if we consider the handle and the rivets or screws connecting it to the container as a single unit, the handle and rivets essentially form a lever-like rod inserted into the side wall of the container, which is indeed the case in reality.

[0012] The handle, and the rivet that connects the handle to the container, is a lever inserted into the container wall. The destructive lever arm of this lever is mainly related to the length of the handle (the furthest distance from the handle rivet hole on the container wall to the top of the handle on the side of the rivet hole). The longer the handle, the longer the destructive lever arm. Since the handle is very long, the handle length of common household two-layer steamers with diameters of 240mm, 260mm, and 280mm is about 62mm to 66mm. Therefore, the destructive lever arm of this lever is very long, and the destructive torque generated is also very large (torque equals force multiplied by lever arm, where force can be considered a constant quantity).

[0013] The radii of the rivet heads on the handles of the aforementioned two-tiered household steamers with diameters of 240mm, 260mm, and 280mm are approximately 4mm, 4mm, and 4 to 4.5mm, respectively. This indicates that the radius of the rivet heads on the handles of existing lightweight household heating containers is very small, resulting in a very small area. Furthermore, the radius of the rivet head is slightly smaller than the radius of the handle tail, so both the radius and area of ​​the handle tail are also very small. The radii and areas of the rivet heads and handle tails of other lightweight household containers are similarly very small.

[0014] Because the radius of the rivet head and the radius of the handle tail of the container wall are very small, and are approximately equal to the lever arms of the inner and outer walls of the container against the destructive force arm of the aforementioned lever, i.e., the opposing lever arms, the opposing lever arms are very small, and the opposing torque is also very small.

[0015] Therefore, the aforementioned levers can easily damage the container wall. Especially over time, when the rivets loosen, they can also easily wear down the rivets that fix the handle, making them smaller and thinner. At the same time, they can easily pry and wear up the fixing holes on the container wall through which the rivets or screws pass, making it easy for the handle to come off.

[0016] To solve the above problems—

[0017] Increase the radius of the rivet head of the container wall handle by 0.1 to 8 times, and increase the radius of the handle tail of the container wall by 0.1 to 18 times, to enhance the strength of the rivet head and handle tail, especially to increase the counterforce arm (length) of the container wall against the aforementioned lever, thereby increasing the counterforce torque.

[0018] Extend the handle (metal leg) tail (2) toward the bottom of the container, preferably perpendicular to the bottom surface of the container, by an extension of 0.1 to 18 times the radius of the handle tail, to form a handle extension tail (3), which also increases the contact area between the handle tail and the outer wall of the container; extend the rivet head toward the opening of the container, preferably perpendicular to the opening surface of the container, by an extension of 0.1 to 8 times the radius of the rivet head, to form a rivet extension head (1), which also increases the contact area between the rivet head and the inner wall of the container.

[0019] The aforementioned "growing radius" or "two extended radii" can be achieved by using methods such as cold heading, turning, forging, stamping, casting, as well as manual grinding, hammering, sawing, and hammering to create "new rivets and new handle tails" to replace the "original rivets and original handle tails" respectively. For riveting relatively large rivet heads to the container wall, both the rivet punch and the rivet base can be made into an arc-shaped sidewall that matches the container wall, or it can be achieved by repeatedly hammering it manually to rivet it to the container wall.

[0020] The aforementioned "two extended radii" not only greatly increase the contact area between the handle tail and the outer wall of the container, as well as the contact area between the rivet head and the inner wall of the container, but also greatly increase the counterforce arm (length) and counterforce torque of the container wall.

[0021] To increase the strength of the handle extension tail (3) and make it less prone to deformation so that it fits better against the outer wall of the container, a rivet can be installed at the end of the handle extension tail (3) to rivet the handle extension tail (3) to the container wall. A support rod (4) can also be added to the handle extension tail (3) and the metal support foot of the handle (at the bend corner), and the tail of the handle extension tail (3) and the support rod (4) can be riveted to the container wall with the newly added rivet.

[0022] Similarly, in order to increase the strength of the rivet extension cap (1) and make it less prone to deformation so that it can fit better on the outer wall of the container, a rivet can be installed at the upward end of the rivet extension cap (1) to rivet the rivet extension cap (1) to the container wall. If the original rivet of the rivet extension cap (1) is installed at a lower position than the container edge (the ring edge of the container mouth that supports the container lid), it is more suitable to add a support rod on the rivet extension cap (1) and the metal support foot of the handle (at the bend corner), and use the newly added rivet to rivet the tail of the support rod and the rivet extension cap (1) to the container wall (at a higher position).

[0023] The above makes—

[0024] The container wall is difficult to deform, the handle can be firmly fixed to the container and the heating container wall, the rivets are difficult to wear down and become smaller and thinner, and the fixing holes on the container wall through which the rivets pass are difficult to pry or grind up.

[0025] Because the handles are very secure, the fixing holes and rivets on the container wall are difficult to pry or shake, making it difficult for liquid to leak from the rivet locations on the container wall. Therefore, the rivets can be installed at a relatively low position on the container wall, making the container more suitable for filling it with a fuller amount of liquid.

[0028] II. Handles on container lids

[0029] When opening or moving a container (including heated containers) lid (hereinafter referred to as the lid), it is almost impossible to always hold it vertically; it is often held sideways. When held sideways, the handle on the lid and the screw connecting the handle are equivalent to a long lever inserted into the lid or handle base. This lever pries the lid, and the lid, in turn, is forced to "pry" the large end of the handle base, and the small end of the handle base is forced to "pry" the bottom surface of the handle (corresponding to the base), also called the mounting surface or mating surface (hereinafter referred to as the handle bottom surface). Because the length of the handle plus the screw connecting the handle is very long, the destructive lever arm is very long, which also generates a large destructive torque (torque equals force multiplied by lever arm; here, force can be considered a constant quantity).

[0030] Since some handle bases do not have clearly defined large and small ends, when "handle base" does not specify the large and small ends, "handle base" refers to the "large end of the handle base", and "handle base radius" refers to the "radius of the large end of the handle base".

[0031] The radius and area of ​​the handle's base (and the screw) are very small. Taking a 240mm diameter household two-layer steamer as an example, the large end diameter of the handle base is approximately 48mm, and the corresponding radius of the handle's base at the small end is approximately 18mm. The lever arm that the handle's base is forced to resist against the destructive force arm of the aforementioned lever, i.e., the opposing force arm, is approximately equal to the radius of the handle's base. The smaller the radius of the handle's base, the smaller the opposing force arm. Therefore, the opposing force arm and opposing torque that the handle's base is forced to resist against the aforementioned lever are also very small, resulting in—

[0032] The aforementioned lever can easily damage the bottom of the handle, the screw, the (nut) threads in the handle (hereinafter referred to as: handle threads), and the hole in the middle of the cover through which the screw passes to fix the handle (hereinafter referred to as: cover fixing hole). Especially over time, when the screw loosens, it can easily wear down the handle threads, making the internal thread hole of the handle larger, making the screw smaller and thinner, causing it to strip (strip the threads). At the same time, it can also further pry and wear up the cover fixing hole, making it easy for the handle to come off.

[0033] The cover, handle base, and handle are connected together by bolts to form an assembly. Because the radius and area of ​​the handle bottom surface (and screw) are too small, it is difficult to prevent the handle and handle base from prying or twisting with a strong arm and torque, which makes the handle screw easy to be damaged. Therefore, only a relatively small force can be used to tighten the handle bolt. So it is difficult to keep the cover, handle base, and handle stable for a long time by directly tightening the handle bolt.

[0034] The metal nut is "embedded" in the bakelite at one end of the bottom surface of the handle. When the handle base is forced to "pry" the bottom surface of the handle, the nut in the middle of the bottom surface will also be pried open. This can easily loosen the nut from the bakelite, wear down the bakelite, and also easily enlarge the fixing hole of the cover.

[0035] In addition, people inevitably grab the handle to turn the lid, or after the lid turns, they inevitably grab the handle to stop it from turning. In both of these types of rotation, the lid (with the handle base) tends to rotate in the opposite direction to the handle. Since the lid has a large radius, mass and inertia, while the handle has a small bottom radius, the torque that prevents the lid from rotating is small. This makes it easy for the lid (or handle base) and the bottom of the handle to rotate and slide, loosening the bolt and loosening the handle.

[0036] To solve the above problems, a handle with a larger bottom radius (e.g., equal to the handle base radius) can be manufactured. This handle radius is larger than the original handle bottom radius but less than or equal to 1.2 times the handle base radius. It can be directly installed on the cover, or the handle base can be connected to the cover first, with the handle base and cover as one assembly, and then the handle can be connected to the handle base, with the handle and handle base as another assembly. The two assemblies form a handle.

[0037] The above increases the force arm of the lever against the handle base to the radius (length) of the handle base, or to a value equal to the radius (length) of the handle base. This significantly increases the counter torque, making it difficult for the lever to pry off the handle base, screw, handle thread, and cover fixing hole. It also significantly increases the radius (force arm) and torque of the handle base that prevents the cover from rotating, making it difficult for the cover (or handle base) and handle base to slip off. This ensures that the cover, handle base, and handle are stable for a long time.

[0038] Methods for directly attaching the handle to the cover include: gluing (water) together; welding can also be used for metal covers and handles; or the traditional method of fixing the handle to the cover can be used, that is: make a hole (nut) in the handle, pass a bolt through the hole in the cover and the hole in the handle, and then tighten the bolt.

[0039] The handle of this type of lid is best made in the shape of a dumbbell or similar object.

[0040] The handle is connected to the handle base via the bottom of the handle, and then to the cap. The connection methods include: snap-on type, bottle cap type, and glue (water) can also be used. For metal caps and handles, welding can also be used.

[0041] a. Snap-on connection

[0042] Make the handle base into a box (connector) similar to a wall socket (recessed panel socket). Drill a hole in the box, then pass a bolt through the fixing hole on the cover and the hole in the box. Then, put a large washer on the bolt and tighten the large washer on the box and cover with a nut.

[0043] The handle base is connected to the wall socket using a snap-fit ​​structure. The handle base and the bottom of the handle are respectively made with the elastic clips (plastic clips) on the panel (cover) of the wall socket and the clip grooves (panel clip grooves) on the bottom box, so that the handle can be snapped onto the handle base just like the panel is snapped onto the bottom box, and the handle can also be removed from the base just like the panel is removed from the bottom box.

[0044] (Large) gaskets can be selected with a length (diameter) only 0.55 to 0.999 times the length of the inner surface of the bottom box (preferably 0.70 to 0.999 times), and an area only 0.55 to 0.999 times the area of ​​the inner surface of the bottom box (preferably 0.70 to 0.999 times), that is, both the length (diameter) and area are slightly smaller than the length (diameter) and area of ​​the inner surface of the bottom box; and have high strength and toughness, such as metal.

[0045] Because wall sockets have a very large area, the force or torque generated by the "elastic clips and clip slots" is very large. Therefore, the "elastic clips and clip slots" can be made relatively small and thin. However, the area of ​​the handle bottom and handle base is relatively small, so the "elastic clips and clip slots" of the handle bottom and handle base can be made larger and thicker. The length and area of ​​the pads should be reduced accordingly.

[0046] b. Bottle cap connection

[0047] The handle base is made into a bottle cap with a hole on the top surface, or an existing bottle cap with a hole on the top surface (such as the cap of a plastic medicine bottle containing 100 tablets of multi-enzyme tablets) is used to replace the handle base. Then, a bolt is passed through the fixing hole on the cap and the hole in the bottle cap. A large washer is then put on the bolt, and a nut is used to tighten the large washer, the bottle cap, and the cap. Finally, the bottle body is screwed into the bottle cap, and the bottle body becomes the handle.

[0048] (Large) gaskets can be selected with the following characteristics: a radius that is only 0.55 to 0.999 times the radius of the inner surface (sealing surface) of the bottle cap (preferably 0.70 to 0.999 times), and an area that is only 0.55 to 0.999 times the area of ​​the inner surface (sealing surface) of the bottle cap (preferably 0.70 to 0.999 times). In other words, it is best if both the radius and area are slightly smaller than the radius of the inner surface of the bottle cap; and high strength and toughness, such as metal.

[0049] The bottle can be made into a dumbbell shape, wider at both ends and narrower in the middle, or it can be a regular bottle. The ring around the bottle mouth is the bottom of the handle.

[0050] Because the gaskets on the inner surface of the bottle cap have a large area, the bottle cap, the gaskets on the inner surface of the bottle cap, and the nut can form a solid whole under the action of the bolt. Also, because the radius of the bottle cap is large, and the radius of the bottle cap is approximately equal to or relatively close to the opposing force arm, the larger the radius of the bottle cap, the larger the opposing force arm, and therefore the larger the opposing torque. This prevents the fixing holes of the cap and the bakelite fibers from being easily loosened by the handle and the screw, making them prone to wear and stripping. It also prevents the metal nut "embedded" in the bakelite from being easily loosened and worn.

[0051] This also allows the bottle cap, the gasket inside the bottle cap, the nut, the bolt, and the bottle body to be firmly fixed to the cap as a whole.

[0052] Pressure cooker lids are heavy, and the high temperature of a pressure cooker can easily soften plastic. However, the aforementioned plastic bottle caps and bodies can be used as handles for pressure cooker lids. One important reason for this is that the washer, which is slightly smaller than the inner surface area of ​​the bottle cap, is added between the bottle cap and the nut. Under the pressure of the nut, it "holds" the bottle cap over a large area, increasing the strength of the top and inner surfaces of the bottle cap and making the threaded part of the bottle cap less prone to deformation. This indirectly increases the strength of the bottle body screwed onto the bottle cap, thus increasing the strength of both the bottle cap and the bottle body. Attached Figure Description

[0054] Figure 3 It is a picture of a pressure cooker lid with a plastic bottle handle.

[0055] Figure 4 This is a photo of a pressure cooker lid with a plastic bottle handle.

[0057] The invention of the container lid handle will be further explained below with reference to the accompanying drawings:

[0058] Figure 4 It is a pressure cooker lid with a plastic bottle handle containing 100 multi-enzyme tablets that has been used for about 1 year. The plastic bottle cap (9) has a diameter of 30 mm, the screw has a diameter (nominal diameter) of 8 mm, and the hole on the top surface of the bottle cap has a diameter of 22 mm.

[0059] The preferred screw diameter and the diameter of the hole cut in the bottle cap are 6 mm, which can ensure the strength of the handle and save materials.

[0060] like Figure 4 When opening a pressure cooker like this, simply push the bakelite (or plastic) vent valve base (11) on the lid along the tangential direction of the lid edge. This will rotate the lid to the open position. Then, grasp the plastic bottle handle to easily lift the lid. Using this method, women and children can easily open the lid with one hand, thus saving materials used in manufacturing pressure cooker lid handles. At the same time, it avoids the problem of the lid fixing holes and bakelite threads being easily loosened by the handle and screw when using ordinary handles on pressure cooker lids, making them prone to wear and stripping. It also avoids the problem of the metal nut "embedded" in the bakelite being loosened and worn. This allows the handle to be firmly fixed to the pressure cooker lid by bolts and nuts.

[0061] The reason why the above method can rotate the pressure cooker lid to the open position by gently pushing the bakelite (or plastic) exhaust valve base (11) on the pressure cooker lid is that the lever arm of pushing the lid is the radius of the lid, and the radius of the lid is very large, which makes the lever arm and torque of pushing the lid very large.

[0062] Furniture and drawers are equivalent to containers, and some furniture doors and drawer panels are equipped with handles similar to those on heated container lids, so the handles of the present invention for container lids can also be used on furniture doors and drawer panels.

[0063] In summary, the handles on the container and heating container of the present invention have a simple, reliable, and durable structure.
