Description

Technical Field

[0001] This utility model belongs to the field of trash can technology, specifically relating to a trash can with an internal opening ring that is easy to stack and its stacking assembly. Background Technology

[0002] Some existing trash can products have a loop at the opening. After the trash bag is put on the opening, the loop is pressed tightly against the opening to secure the trash bag and prevent it from slipping off the opening due to the weight of the trash.

[0003] The existing trash can opening rings are one-piece molded structures and pre-installed on the trash can openings. The trash cans are transported in a stacked manner, and the opening ring design has two forms:

[0004] 1. External mouth ring: The mouth ring is designed to be attached to the outside of the bucket opening, and the pre-installed mouth ring does not affect the internal diameter of the bucket opening.

[0005] Second, the mouth ring is built-in, that is, the mouth ring is placed inside the mouth of the trash can. This design can make the appearance of the trash can more simple and beautiful. For example, the trash can disclosed in the patent document with publication number CN2675604Y has a mouth that is wider at the top and narrower at the bottom. There is a pressure ring at the mouth with an outer diameter that is slightly smaller than the inner diameter of the mouth. At the same time, another advantage of the built-in mouth ring is that the assembly relationship of other parts at the mouth (such as the body of the can, the lid of the can, etc.) is not affected by the mouth ring. They can be configured as needed without the need for additional molds.

[0006] However, if the pre-installed built-in mouth ring is a subsequent addition to a mature product, without redesigning the size of the barrel and opening a new mold, it will result in a reduction in the number of barrels that can be stacked in a unit space during transportation, an increase in transportation volume, and an increase in transportation costs.

[0007] To address the aforementioned issues, these trash cans are typically transported in a stacked manner, with the lid rings placed inside the top bin. However, the applicant's products are primarily sold in overseas markets. Due to high labor costs, large overseas retailers (such as Walmart and Costco) do not assemble the semi-finished components transported in bulk; instead, they simply stack them for sale. Since multiple lid rings are placed inside the top bin, it is easy for retail staff to miss or take all the lid rings when packing for customers or for customers to retrieve them themselves. This results in losses for the retailer, increased after-sales costs, or the need for users to perform additional after-sales operations (such as returning to the retailer to retrieve lid rings or reporting missing items to the retailer).

[0008] In conclusion, it is particularly necessary to design a trash can with an internal ring that can be sold as a set of "one bin and one ring" without hindering the stacking of multiple bins. Summary of the Invention

[0009] In view of the problems in the related technologies, this utility model proposes a built-in ring trash can and its stacking assembly that are easy to stack, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0010] The technical solution of this utility model is implemented as follows:

[0011] A built-in ring trash can that is easy to stack, comprising a can body and a bag-pressing ring, wherein the can body and the bag-pressing ring are separate components;

[0012] The pressure bag ring includes a first moving member and a second moving member that are separately arranged, and the first moving member and the second moving member are rotatably connected by a hinge structure.

[0013] A matching locking structure is also provided between the first moving member and the second moving member;

[0014] When the locking structure is unlocked, the first moving member and the second moving member move closer to each other by rotation and fold. The vertical height of the folded pressure bag ring after it is placed inside the barrel body is h. The barrel body is wider at the top and narrower at the bottom. Different barrel bodies can be stacked on top of each other. The bottoms of the stacked barrel bodies do not touch each other and the distance between them is H, where H≥h.

[0015] When the locking structure is locked by external force, the first moving part and the second moving part are stuck and cannot rotate on their own. The stuck first moving part and the second moving part form the bag pressing ring with a hollow inner ring. The bag pressing ring is stuck inside the opening of the barrel body.

[0016] An external force applied to the locking structure can unlock it.

[0017] The inventors discovered that to avoid the stacked barrels being too tightly fitted and difficult to separate later, a certain space is usually reserved between the stacked barrels. Therefore, this utility model, while retaining the built-in design of the mouth ring, designs the mouth ring as a foldable structure and places it between the stacked barrels. This ensures that the number of barrels that can be stacked in a unit space is not reduced due to the mouth ring design. At the same time, this utility model can be sold in a set of "one barrel, one ring", eliminating the need for secondary sorting in the store and avoiding problems such as missing parts or taking multiple mouth rings by mistake.

[0018] The bag-pressing ring can be a closed ring or a semi-closed ring, both of which can achieve the function of pressing the garbage bag. However, in order to prevent the bag-pressing ring from easily deforming, tilting, or the end from scratching the user's skin, it is generally preferred to design it as a closed ring.

[0019] The locking structure can be designed as a detachable adhesive, Velcro, or snap-fit ​​structure, etc. Preferably, the first moving member has an arc-shaped snap-fit ​​slope, and the second moving member has a slot that adapts to the snap-fit ​​slope. The arc-shaped direction of the snap-fit ​​slope is at the same center as the rotation trajectory of the first and second moving members, and the thickness of the snap-fit ​​slope increases along the direction of the flat rotation trajectory of the first and second moving members.

[0020] The locking structure is composed of the engagement ramp and the slot. Compared with other conventional engagement structures, the engagement ramp of this invention matches the rotation trajectory of the moving part and its thickness increases gradually, so that the force applied by the user during installation gradually increases, resulting in a more natural transition and reducing the difficulty of installation. It also guides the user during installation, preventing excessive force from causing structural damage.

[0021] Preferably, the hinge structure protrudes outward from the outside of the first and second moving members, so that the first and second moving members can be completely folded, thereby minimizing the thickness of the pressure bag ring after folding.

[0022] Preferably, the main structure of the first moving member is a first frame with an open end, and the main structure of the second moving member is a second frame with an open end. The open frame can support the moving member to produce a certain elastic deformation, which facilitates the assembly of the end hinge structure. The open ends of the first frame and the second frame are opposite to each other and are connected by the hinge structure at the end.

[0023] Preferably, the first frame with an open end has two first ends, the two first ends extend outward from the frame to form two bearing seats, and the outer surfaces of the two bearing seats protrude in opposite directions to form a rotating shaft;

[0024] The second frame with an open end has two second ends, which extend outward from the frame to form two convex shafts, each of which has a shaft hole adapted to the rotating shaft.

[0025] The rotating shaft is rotatably engaged within the shaft hole, and the rotating shaft and the shaft hole form the hinge structure.

[0026] Preferably, the cross-sectional structure of the first frame is an inverted L-shape, having a first horizontal beam and a first vertical beam; the two ends of the first vertical beam extend outward to form two protrusions, and the opposite sides of the two protrusions protrude in a direction close to each other to form the locking slope; the rotating shaft is suspended above the protrusions, and the central axis of the rotating shaft is parallel to the first horizontal beam.

[0027] The second frame has an inverted L-shaped cross-section and has a second horizontal beam and a second vertical beam. The opposing outer circumferential surfaces at both ends of the second vertical beam are recessed inward to form the slot, and the convex shaft is provided above the slot.

[0028] The extra protruding tabs that are not connected to the rotating shaft can undergo a certain degree of elastic deformation, making it easy to engage with the slot. At the same time, the engagement slope and slot are not exposed, preventing dirt from accumulating and resulting in a relatively simple appearance.

[0029] In actual production, the slot and the engagement ramp are small structures. If the user applies too much force, the moving parts may rotate too much. Therefore, preferably, the outer peripheral surface of the second vertical beam near the end is recessed inward to form a protrusion groove that fits the protrusion. The bottom of the protrusion groove is further recessed to form the slot. When the engagement ramp and the slot are installed in place, the protrusion is locked in the protrusion groove, preventing the user from rotating it too much during installation and thus damaging the parts.

[0030] Preferably, a portion of the outer peripheral surface of the convex shaft protrudes outward in the peripheral direction to form a limiting protrusion, the first crossbeam is disposed on the rotation trajectory of the limiting protrusion, and the rotation angle of the first moving member and the second moving member is limited by the limiting protrusion.

[0031] When the locking plate is engaged in the slot, the limiting protrusion approaches or contacts the end of the first crossbeam. By designing the limiting protrusion to cooperate with the aforementioned tab groove, it prevents the user from over-rotating during installation, thus avoiding damage to the parts.

[0032] Preferably, the locking ramp has a slope surface, a flat top surface, and a vertical surface connected in sequence; during locking, the end of the second vertical beam successively contacts and slides over the slope surface and the flat top surface, thereby locking the locking ramp into the locking groove. The slope surface design supports the effect of gradually increasing force during installation, and the vertical surface can provide a clear tactile feel of locking in place when installed and makes the locking ramp less likely to fall out of the locking groove.

[0033] This utility model also discloses a solution for a foot-operated flip-top trash can that can be sold as a set, which includes a lid for covering the internal space of the can, a pre-installed lock, a foot pedal, a connector, and a transmission support rod.

[0034] At least one set of matching buckle structures is provided between the bucket lid and the pre-installed lock. The bucket lid and the pre-installed lock are detached and connected to each other through the buckle structures. The buckle structures are not particularly limited, as long as they are small in size, do not hinder the stacking of the bucket body, and can connect the bucket lid.

[0035] The pre-installed locking components are pre-installed on the top of the transmission support rod and the barrel body respectively by means of rotational connection. The rotational connection position of the pre-installed locking component and the transmission support rod is further forward than the rotational connection position of the pre-installed locking component and the barrel body. The barrel lid and the pre-installed locking component are coaxial and rotatably connected to the barrel body on the same side. The coaxial design also means that the barrel lid and the pre-installed locking component have only one movement trajectory, that is, they can only be locked by rotating to the target locking angle (generally rotating to the point where the two are in contact) and then locking by the buckle structure. This makes installation convenient and reduces the chance of users damaging parts during installation.

[0036] The front part of the connector is rotatably connected to the foot pedal, the middle part of the connector is rotatably connected to the bottom of the barrel, and the rear part of the connector is rotatably connected to the bottom end of the transmission support rod.

[0037] The front surface of the bucket body is recessed to at least beyond the rotating connection part of the foot pedal and the connector to form a clearance groove. The clearance groove extends through to the bottom surface of the bucket body, and the capacity of the clearance groove is greater than or equal to the volume of the foot pedal.

[0038] The rear barrel surface of the barrel is recessed forward to form an inclined support rod groove. The inclined direction of the support rod groove matches the barrel body which is wider at the top and narrower at the bottom. The transmission support rod is located in the support rod groove in an inclined state, thereby supporting the pre-installation of the transmission support rod and the stacking of the barrel body.

[0039] When the buckle structure is not assembled and connected, the bucket lid can be flipped backward to face downward. There is a space reserved between the bucket lid and the bucket body for overlapping. The foot pedal can be rotated upward and folded into the interior of the clearance groove, thereby supporting the pre-installation of the foot pedal and the overlapping of the bucket body.

[0040] When the buckle structure is assembled, the bucket lid is indirectly connected to the foot pedal through a pre-installed locking component, a transmission support rod, and a connecting component. Stepping on the foot pedal can indirectly drive the bucket lid to open and close.

[0041] Preferably, the inner sidewall of the barrel body is provided with an inwardly convex supporting surface near the barrel opening, and the supporting surface supports the bag pressing ring.

[0042] This utility model also discloses a stackable assembly, including several trash cans. Each trash can includes a separate body and a bag-pressing ring. Several bodies that are wider at the top and narrower at the bottom are stacked together. The bottoms of the stacked trash cans do not contact each other to form a space, in which the bag-pressing ring is placed. Attached Figure Description

[0068] Example 1

[0069] like Figures 1 to 13 As shown, a built-in ring trash can that is easy to stack includes a bag-pressing ring R and a can body 3. The bag-pressing ring R and the can body 3 are separate parts. The bag-pressing ring R can be a closed ring (i.e., in this embodiment) or a semi-closed ring.

[0070] The pressure bag ring R includes a first moving member 1 and a second moving member 2 that are separately arranged, and the first moving member 1 and the second moving member 2 are rotatably connected by a hinge structure.

[0071] A matching locking structure is also provided between the first moving member 1 and the second moving member 2;

[0072] When the locking structure unlocks, the first moving member 1 and the second moving member 2 move closer to each other and fold together by rotation, as shown in the reference. Figure 1The vertical height of the folded pressure ring R after being placed inside the barrel body 3 is h. The barrel body 3 is wider at the top and narrower at the bottom. Different barrel bodies 3 can be stacked on top of each other. The bottoms of the stacked barrel bodies 3 do not touch each other and the distance between them is H, where H≥h.

[0073] When the locking structure is locked by external force, the first moving member 1 and the second moving member 2 are locked and cannot rotate on their own. The locked first moving member 1 and the second moving member 2 form the hollow inner ring of the pressure bag ring R, as shown in the figure. Figure 2 The bag-pressing ring R is secured to the inside of the barrel opening of the barrel body 3;

[0074] An external force applied to the locking structure can unlock it.

[0075] In this embodiment, the first moving member 1 is provided with an arc-shaped engagement slope 101a, and the second moving member 2 is provided with a groove 203a that adapts to the engagement slope 101a. The arc-shaped direction of the engagement slope 101a is at the same center as the rotation trajectory of the first moving member 1 and the second moving member 2 (see reference). Figure 9 As shown), the thickness of the card slope 101a increases along the direction of the rotation trajectory of the first moving member 1 and the second moving member 2.

[0076] The locking structure is composed of the locking plate 101a and the locking groove 203a.

[0077] In this embodiment, the hinge structure protrudes outward from the outer side of the first moving member 1 and the second moving member 2, thereby allowing the first moving member 1 and the second moving member 2 to be completely folded (e.g., Figure 3 As shown in the figure, this minimizes the thickness of the folded-down pressure ring R.

[0078] In this embodiment, the main structure of the first moving member 1 is a C-shaped first frame with an open end, and the main structure of the second moving member 2 is a C-shaped second frame with an open end. The open frame can support the moving member to produce a certain elastic deformation, which facilitates the assembly of the end hinge structure. The open ends of the first frame and the second frame are opposite each other and are connected by the hinge structure at the end to form a rotational connection.

[0079] In this embodiment, the first frame with an open end has two first ends. The two first ends extend outward from the frame to form two bearing seats 102. The outer surfaces of the two bearing seats 102 protrude in opposite directions to form rotating shafts 103. The tail of the rotating shaft 103 away from the bearing seat 102 is provided with a protrusion to prevent it from disengaging from the shaft hole 201a.

[0080] The second frame with an open end has two second ends, which extend outward from the frame to form two protruding shafts 201. Each of the protruding shafts 201 has a shaft hole 201a adapted to the rotating shaft 103.

[0081] The rotating shaft 103 is rotatably engaged in the shaft hole 201a, and the rotating shaft 103 and the shaft hole 201a form the hinge structure.

[0082] In this embodiment, the cross-sectional structure of the first frame is an inverted L-shape, having a first horizontal beam 104 and a first vertical beam 105; the two ends of the first vertical beam 105 extend outward to form two protrusions 101, and the opposite sides of the two protrusions 101 protrude in a direction close to each other to form the locking slope 101a; the rotating shaft 103 is suspended above the protrusions 101, and the central axis of the rotating shaft 103 is parallel to the first horizontal beam 104; a number of reinforcing ribs are provided at the angle between the first vertical beam 105 and the first horizontal beam 104.

[0083] The second frame has an inverted L-shaped cross-section and has a second horizontal beam 202 and a second vertical beam 203. The two opposite outer peripheral surfaces of the two ends of the second vertical beam 203 are recessed inward to form the slot 203a. The convex shaft 201 is provided above the slot 203a. Several reinforcing ribs are provided at the angle between the second vertical beam 203 and the second horizontal beam 202.

[0084] The protruding tab 101, which is not connected to the rotating shaft 103, can undergo a certain elastic deformation, which facilitates engagement with the slot 203a. At the same time, it prevents the engagement slope 101a and the slot 203a from being exposed, thus avoiding the accumulation of dirt and grime, and resulting in a simpler appearance.

[0085] In this embodiment, the outer peripheral surface of the second vertical beam 203 near its end is recessed inward to form a protrusion groove 203b that adapts to the protrusion 101. The bottom of the protrusion groove 203b is further recessed to form the locking groove 203a. When the locking slope 101a and the locking groove 203a are installed in place, the protrusion 101 is locked in the protrusion groove 203b, preventing the user from over-rotating during installation and causing damage to the parts.

[0086] In this embodiment, a portion of the outer peripheral surface of the convex shaft 201 protrudes outward in the peripheral direction to form a limiting protrusion 201b. The first crossbeam 104 is disposed on the rotation trajectory of the limiting protrusion 201b, and the rotation angle of the first moving member 1 and the second moving member 2 is limited by the limiting protrusion 201b.

[0087] Reference Figure 11When the locking protrusion 101a is engaged with the locking groove 203a, the limiting protrusion 201b approaches or contacts the end of the first crossbeam 104, and the end of the first crossbeam 104 is thickened. By designing the limiting protrusion 201b to cooperate with the aforementioned protrusion groove 203b, the user is prevented from over-rotating during installation, thus avoiding damage to the parts.

[0088] Specifically, the locking ramp 101a has a slope surface, a flat top surface, and a vertical surface connected in sequence. During locking, the end of the second vertical beam 203 successively contacts and slides over the slope surface and the flat top surface, thereby locking the locking ramp 101a into the locking groove 203a. The slope surface design supports the effect of gradually increasing force during installation, and the vertical surface provides a clear tactile feel of locking in place when installed and makes it difficult for the locking ramp 101a to disengage from the locking groove 203a.

[0089] This embodiment also includes a bucket lid 6 for covering the internal space of the bucket body 3, a pre-installed lock 4, a foot pedal 7, a connector 8, and a transmission support rod 5.

[0090] At least one set of matching snap-fit ​​structures is provided between the bucket lid 6 and the pre-installed lock 4. The bucket lid 6 and the pre-installed lock 4 are detachably connected to each other through the snap-fit ​​structures. The volume of the pre-installed lock 4 is much smaller than that of the bucket lid 6.

[0091] The buckle structure is not particularly limited, as long as it is small in size, does not obstruct the stacking of the bucket body 3, and can connect to the bucket lid 6. In this embodiment, the pre-installed locking component 4 is provided with two slidingly connected levers 401, and the bucket lid 6 is provided with a socket 601 for the levers 401 to be engaged. By moving the levers 401 to engage or disengage from the socket 601, the connection between the pre-installed locking component 4 and the bucket lid 6 can be controlled.

[0092] The pre-installed locking component 4 is pre-installed on the top of the transmission support rod 5 and the barrel body 3 respectively in a rotatable connection manner. The rotatable connection position of the pre-installed locking component 4 and the transmission support rod 5 is further forward than the rotatable connection position of the pre-installed locking component 4 and the barrel body 3. The barrel lid 6 and the pre-installed locking component 4 are coaxial and rotatably connected to the barrel body 3 on the same side.

[0093] The front part of the connector 8 is rotatably connected to the foot pedal 7, the middle part of the connector 8 is rotatably connected to the bottom of the barrel body 3, and the rear part of the connector 8 is rotatably connected to the bottom end of the transmission support rod 5.

[0094] The front surface of the barrel body 3 is recessed to at least beyond the rotating connection part of the foot pedal 7 and the connecting part 8, forming a clearance groove 301. The clearance groove 301 extends through to the bottom surface of the barrel body 3, and the capacity of the clearance groove 301 is greater than or equal to the volume of the foot pedal 7.

[0095] The rear surface of the barrel body 3 is recessed forward to form an inclined support groove 302. The inclined direction of the support groove 302 matches the barrel body 3, which is wider at the top and narrower at the bottom. The transmission support rod 5 is located in the support groove 302 in an inclined state, thereby supporting the pre-installation of the transmission support rod 5 and the stacking of the barrel body 3.

[0096] When the buckle structure is not assembled and connected, the bucket lid 6 can be flipped backward to face downward. There is a space reserved between the bucket lid 6 and the bucket body 3 for overlapping. The foot pedal 7 rotates upward and folds into the interior of the clearance groove 301, thereby supporting the pre-installation of the foot pedal and the overlapping of the bucket body 3.

[0097] When the buckle structure is assembled, the bucket lid 6 is indirectly connected to the foot pedal 7 through the pre-installed locking component 4, the transmission support rod 5 and the connecting component 8. Stepping on the foot pedal 7 can indirectly drive the bucket lid 6 to open and close.

[0098] In this embodiment, the inner sidewall of the barrel body 3 is provided with an inwardly convex supporting surface 303 near the barrel opening, and the supporting surface 303 supports the bag pressing ring R.

[0099] Example 2

[0100] A stackable assembly includes several trash cans of Embodiment 1. Each trash can includes a separate can body 3 and a bag-pressing ring R. Several can bodies 3, which are wider at the top and narrower at the bottom, are stacked together. The bottoms of the stacked trash cans do not contact each other to form a space, in which the bag-pressing ring R is placed.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
