Description

Technical Field

[0001] This utility model relates to the field of trash cans, and in particular to a double-opening flip-top assembly and the trash can thereof. Background Technology

[0002] Trash cans are typically placed in offices, schools, or homes, where users dispose of their trash to maintain a clean and tidy environment. In practice, when disposing of small pieces of trash, users prefer a smaller opening to prevent direct visibility of the accumulated garbage; conversely, when disposing of larger pieces, users prefer a larger opening for easy placement. However, because excessively large trash cans negatively impact aesthetics, existing trash cans typically only have a single, fixed-size opening at the top, failing to meet market demands. Currently, there are also trash cans with two separate openings, but these are each equipped with an independent cover, resulting in a larger overall opening area and consequently a larger footprint, failing to meet the user's requirement for a smaller trash can in the aforementioned environments. Utility Model Content

[0003] Based on this, the purpose of this utility model is to provide a double-opening flip-top assembly and its trash can, which has the advantages of multiple functions and simple structure.

[0004] A double-opening flip-top assembly includes a mounting cover and a bucket lid. The mounting cover has a flip-top opening in the middle. The bucket lid has a first rotating shaft and a second rotating shaft on both sides. The first rotating shaft is coaxially arranged to form a first rotation axis. The bucket lid flips along the first rotation axis in a first direction. The second rotating shaft is coaxially arranged to form a second rotation axis. The bucket lid flips along the second rotation axis in a second direction opposite to the first direction. The flip-top opening has a first shaft support for supporting the first rotating shaft and a second shaft support for supporting the second rotating shaft. The first shaft support has a first opening facing the second direction, and the diameter of the first opening is not smaller than that of the first rotating shaft. The second shaft support has a second opening facing the first direction, and the diameter of the second opening is not smaller than that of the second rotating shaft.

[0005] The double-opening flip-top assembly described in this utility model has a simple structure and small size. The lid can have two flipping modes, thereby meeting the user's needs for two opening diameters.

[0006] Furthermore, the first rotation axis is located in the middle of the bucket lid, which allows for stable support of the bucket lid while minimizing the opening diameter.

[0007] Furthermore, the lid is provided with a counterweight protrusion located on the side of the second rotation axis away from the first rotation axis. This counterweight protrusion can drive the lid to automatically reset, realizing the automatic closing of the trash can, and at the same time ensuring that the lid is balanced, i.e., horizontal, when closed, preventing the lid from tilting.

[0008] Furthermore, the lid has a first groove and a second groove on both sides. The first rotating shaft is disposed in the first groove, and the first shaft support is accommodated in the first groove. The second rotating shaft is disposed in the second groove, and the second shaft support is accommodated in the second groove. This structure allows for a tighter fit between the lid and the mounting cover, reducing the gap between them and minimizing odor problems from the trash can.

[0009] Furthermore, the sidewall of the first groove away from the second rotation axis is provided with a first abutment surface. The first shaft support includes a first support block and a first limiting block. The first support block is arc-shaped, and the first opening is formed on the first support block. The first limiting block is disposed on the side of the first support block near the second rotation axis and is located on the path of the first abutment surface when it rotates in the first direction, thereby achieving abutment between the first abutment surface and the first limiting block. The sidewall of the second groove away from the first rotation axis is provided with a second abutment surface. The second shaft support includes a second support block and a second limiting block. The second support block is arc-shaped, and the second opening is formed on the second support block. The second limiting block is disposed on the side of the second support block near the first rotation axis and is located on the path of the second abutment surface when it rotates in the second direction, thereby achieving abutment between the second abutment surface and the second limiting block. Its structure is simple and can limit the rotation angle of the lid, preventing the lid from falling off due to excessive flipping.

[0010] Furthermore, the sidewall of the first groove away from the second rotation axis extends in the first direction and protrudes to form an abutment portion. When the lid rotates in the first direction until the abutment portion abuts against the first limiting block, the rotation angle of the lid is less than 90 degrees. This structure ensures that the lid can be reset by the counterweight protrusion when in a slightly open state, avoiding the lid from over-flipping and failing to automatically reset.

[0011] Furthermore, the mounting cover includes a top plate and an outer limiting ring. The top plate has a flip-up opening in the middle, and the outer periphery of the top plate is folded downwards to form the outer limiting ring. Its simple structure facilitates the detachable installation of the mounting cover, making it convenient for users to remove and replace the garbage bags in the trash can.

[0012] Furthermore, the mounting cover is also provided with an inner limiting ring, which is located inside the top plate and surrounds the flip opening. The first shaft support and the second shaft support are disposed on the inner limiting ring, thereby limiting the bucket lid and preventing displacement.

[0013] Furthermore, the mounting cover is also provided with reinforcing ribs, which are connected to the top plate, the outer limiting ring, and the inner limiting ring. Several of these reinforcing ribs are spaced apart and surround the flip-up opening. This structure enhances the strength of the mounting cover.

[0014] The present invention discloses a trash can comprising a can body and a double-opening flip-top assembly as described above. The can body has an internal cavity for holding trash, and a disposal opening communicating with the cavity is provided at the top. The double-opening flip-top assembly is detachably fitted over the disposal opening, and the flip-top opening corresponds to the disposal opening. Its structure is simple and can meet user needs.

Detailed Implementation

[0023] This utility model discloses a trash can, which includes a can body 1 and a double-opening flip-top assembly. The can body 1 has an internal cavity 11 for placing trash, and a disposal port 12 communicating with the cavity 11 is opened on the top. The double-opening flip-top assembly is detachably installed at the disposal port 12.

[0024] The double-opening flip-top assembly includes a mounting cover 2 and a lid 3. The mounting cover 2 is detachably mounted on the top of the bin body 1. The lid 3 is rotatably connected to the mounting cover 2. When no garbage needs to be disposed of, the receiving cavity 11 is covered by the lid 3. When garbage needs to be disposed of, the lid 3 is pressed to flip it relative to the mounting cover 2, opening the receiving cavity 11 for garbage disposal. For easy movement, casters 4 are also provided at the bottom of the bin body 1.

[0025] The mounting cover 2 is integrally formed through processes such as injection molding, and includes a top plate 21, an outer limiting ring 22, an inner limiting ring 23, reinforcing ribs 24, a first shaft support 25, and a second shaft support 26. A flip-up opening 211 is provided in the center of the top plate 21, which corresponds to the dispensing opening 12. The outer periphery of the top plate 21 is folded downwards to form the outer limiting ring 22, which is fitted onto the outside of the barrel body 1 and conforms to its shape. When the mounting cover 2 is fitted onto the top of the barrel body 1, the outer limiting ring 22 fits snugly against the outer wall of the barrel body 1. The inner limiting ring 23 is located inside the top plate 21 and surrounds the flip-up opening 211, and its shape conforms to the shape of the barrel lid 3. To improve the structural strength of the mounting cover 2, reinforcing ribs 24 are also provided. Several reinforcing ribs 24 are connected to the top plate 21, the outer limiting ring 22, and the inner limiting ring 23, and are spaced apart around the flip-up opening 211. The first shaft support 25 and the second shaft support 26 are set on the inner limiting ring 23 to support the bucket lid 3.

[0026] The bucket lid 3 has a first rotating shaft 31 and a second rotating shaft 32 on both sides. The two first rotating shafts 31 are coaxially arranged, and their axial direction forms a first rotation axis 5. When one side of the bucket lid 3 is pressed, the bucket lid 3 flips along the first rotation axis 5 in a first direction 6. The second rotating shaft 32 is coaxially arranged, and its axial direction forms a second rotation axis 7. When the other side of the bucket lid 3 is pressed, the bucket lid 3 flips along the second rotation axis 7 in a second direction 8, which is opposite to the first direction 6.

[0027] There are two first shaft supports 25, each corresponding to a first rotating shaft 31, used to support the first rotating shaft 31 so that the first rotating shaft 31 can rotate within the first shaft support 25. The first shaft support 25 is provided with a first opening 251 facing the second direction 8, the diameter of the first opening 251 being not smaller than the first rotating shaft 31, so that when the bucket lid 3 is flipped about the second axis of rotation 7 along the second direction 8, the first rotating shaft 31 can be disengaged from the first shaft support 25.

[0028] There are two second shaft supports 26, each corresponding to a second rotating shaft 32, used to support the second rotating shaft 32 so that the second rotating shaft 32 can rotate within the second shaft support 26. The second shaft support 26 is provided with a second opening 261 facing the first direction 6, the diameter of the second opening 261 being not smaller than that of the second rotating shaft 32, so that when the bucket lid 3 is flipped about the first axis of rotation 5 along the first direction 6, the second rotating shaft 32 can be disengaged from the second shaft support 26.

[0029] The positions of the first rotation axis 5 and the second rotation axis 7 can be designed according to the required opening diameter of the lid 3 after it is flipped. Preferably, the first rotation axis 5 is located in the middle of the lid 3, and the opening diameter of the flip-opening opening 211 after the lid 3 is flipped is a small diameter; the second rotation axis 7 is located off the middle, and the opening diameter of the flip-opening opening 211 after the lid 3 is flipped is a large diameter, thereby meeting the user's need for two opening diameters of the trash can.

[0030] To ensure a tighter fit between the lid 3 and the inner limiting ring 23 and to prevent users from easily seeing the garbage inside, the lid 3 has a first groove 33 and a second groove 34 on both sides. The first rotating shaft 31 is located in the first groove 33, and the first shaft support 25 is housed in the first groove 33. The second rotating shaft 32 is located in the second groove 34, and the second shaft support 26 is housed in the second groove 34.

[0031] To prevent the lid 3 from detaching from the mounting cover 2 due to excessive rotation angle, which would cause inconvenience to the user, a first abutment surface 331 is provided on the side wall of the first groove 33 away from the second rotation axis 7. The first shaft support 25 includes a first support block 252 and a first limiting block 253. The first support block 252 is arc-shaped, and a first opening 251 is formed on the first support block 252. The first limiting block 253 is located on the side of the first support block 252 near the second rotation axis 7 and is located on the path of the first abutment surface 331 when it rotates in the first direction 6, thereby achieving abutment between the first abutment surface 331 and the first limiting block 253. The second groove 34 has a second abutment surface 341 on its side wall away from the first rotation axis 5. The second shaft support 26 includes a second support block 262 and a second limiting block 263. The second support block 262 is arc-shaped, and a second opening 261 is opened on the second support block 262. The second limiting block 263 is disposed on the side of the second support block 262 close to the first rotation axis 5 and is located on the path of the second abutment surface 341 when it rotates in the second direction 8, thereby realizing the abutment surface 341 and the second limiting block 263.

[0032] In practical use, when the opening diameter of the flip-top 211 is small, the user will want the lid 3 to automatically reset after opening. To address this, the lid 3 is provided with a counterweight protrusion 35, located on the side of the second rotation axis 7 away from the first rotation axis 5. Furthermore, the sidewall of the first groove 33, away from the second rotation axis 7, extends in the first direction 6 and protrudes to form an abutment portion 332. When the lid 3 rotates along the first direction 6 until the abutment portion 332 abuts against the first limiting block 253, the rotation angle of the lid 3 is less than 90 degrees.

[0033] When there is no need to dispose of garbage, since the first pivot 31 and the second pivot 32 of the lid 3 are placed on the first support 25 and the second support 26 respectively, there are a total of four support points. At this time, the lid 3 covers the flip opening 211, thereby blocking the disposal opening 12 of the body 1, which has the effect of blocking odor and improving aesthetics.

[0034] When disposing of a small amount of trash, the user can press the left side of the trash can, disengaging the second pivot 32 from the second pivot support 26, causing the lid 3 to rotate in the first direction 6 until the contact part 332 abuts against the first limiting block 253. At this point, the maximum opening diameter of the flip-top opening 211 is half that of the disposal opening 12, and the flip angle of the lid 3 is less than 90 degrees. Please refer to [link / reference]. Figure 5 For ease of observation, the attached diagram is presented as an exploded view. In reality, the first rotating shaft 31 will remain in contact with the first shaft support 25, rather than the lid 3 completely detaching from the mounting cover 2 after rotation. When the user throws in the trash, the lid 3 rotates in the opposite direction under the weight of the counterweight boss 35 until the second rotating shaft 32 abuts against the second shaft support 26, thus resetting the lid 3.

[0035] When disposing of large amounts of trash or when the trash can needs to remain open, the user can press the left side of the trash can. This disengages the first pivot 31 from the first support 25, causing the lid 3 to rotate in the second direction 8 until the second contact surface 341 contacts the second limit block 263. (See also...) Figure 6 For ease of observation, the attached diagram is presented as an exploded view. In reality, the second rotating shaft 32 remains in contact with the second shaft support 26, rather than the lid 3 completely detaching from the mounting cover 2 after rotation. At this time, the open diameter of the flip-top opening 211 is greater than half of the dispensing opening 12, and the flip angle of the lid 3 is greater than 90 degrees. Due to the different gravity on both sides of the second rotating axis 7, the tilted part of the lid 3 will drive the lid 3 to continue rotating in the second reverse direction. The contact between the second abutment surface 341 and the second limiting block 263 prevents the lid 3 from continuing to rotate in the second reverse direction, thus preventing the lid 3 from automatically resetting and keeping it in the open state. After throwing in the trash, the user pushes the lid 3 to rotate in the reverse direction until the first rotating shaft 31 contacts the first shaft support 25, thereby resetting the lid 3.

[0036] This utility model discloses a double-opening flip-top assembly and trash can, which has a simple structure and small size. The lid can have two flipping modes to meet users' needs for two different opening diameters. Simultaneously, the trash can can also achieve two open modes: automatic lid reset and a continuously open mode, satisfying different user requirements.
