[0002] Trash cans are placed in all public places in the city, such as shopping malls, hotels, restaurants, office buildings, and offices, to facilitate people's disposal of paper scraps and other garbage. Most existing trash cans are made of metal or plastic. When in use, a plastic bag is placed inside, and when there is a lot of garbage, the bag can be tied up and thrown away. However, because of their fixed structure, they are bulky and inconvenient to carry around, have poor mobility, and cannot meet the needs of special situations. In addition, each time they are used, an inner bag needs to be put on for easy emptying, which is quite inconvenient.
[0003] Therefore, in many special occasions, such as outdoors, high-end clubs or hospitals, people have an increasing demand for disposable paper trash cans. However, when using existing paper trash cans, bacteria can easily grow and produce odors, which is not good for human health. Moreover, current paper trash cans are generally molded in one piece, and the volume of paper trash cans is limited. Based on the above, those skilled in the art provide a disposable paper trash can with a reusable lid to solve the problems mentioned in the background art. Utility Model Content

The barrel body includes a barrel body and a barrel bottom, and a first side is formed on the barrel body. The lid includes a lid top and a lid body. A first fold line for opening and closing the lid top is provided at the connection between the lid top and the lid body. A limiting strip is provided on the side of the lid top near the lid body. The outer wall of the limiting strip is tangent to the inner wall of the lid top. A first stop strip that cooperates with the limiting strip and a second stop strip that cooperates with the first side are provided on the inner wall of the lid body. The first stop strip is an inclined surface on the side near the lid top.
[0006] In a preferred embodiment, a retaining strip is formed on the inner wall of the cover between the first and second retaining strips, and a first tear line is formed between the top of the cover and the second retaining strip.
[0007] In a preferred embodiment, a second tear line is formed between the bottom of the bucket and the body of the bucket, and a second crease line is formed on the bottom of the bucket.
[0008] In a preferred embodiment, a groove is formed on the bottom of the bucket, a pressing plate is disposed in the groove, a third crease line is formed on the pressing plate that mates with the second crease line, and a locking element is disposed on the side of the pressing plate away from the third crease line, and a notch is disposed on the body of the bucket that mates with the locking element.
[0009] In a preferred embodiment, the bottom of the bucket is provided with a circular hole for connecting a handle, and the handle is provided with a first limiting buckle that cooperates with the circular hole.
[0010] In a preferred embodiment, a first skirt strip is provided on the inner side of the barrel near the bottom of the barrel, and the top surface of the first skirt strip engages with one side of the bottom of the barrel.
[0011] In a preferred embodiment, a second skirt strip is provided on the side of the bottom of the bucket near the bucket body, and the outer wall of the second skirt strip is tangent to the inner wall of the bucket body.
[0012] In a preferred embodiment, the bucket body is provided with symmetrical holes, and a handle is movably connected to the holes, with a second limiting buckle at both ends of the handle cooperating with the holes.
[0013] In a preferred embodiment, the second limiting buckle includes a curved tear line and a connecting crease line.
[0014] In a preferred embodiment, an observation opening extending along the height direction of the barrel is formed on the side wall of the barrel, and a plastic film is disposed inside the observation opening.
[0015] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0016] In a preferred embodiment of this utility model, a trash can is formed by combining a bucket body and a lid. The bucket body includes a bucket body and a bucket bottom, and the lid includes a lid top and a lid body. A first side of the bucket body cooperates with a first stop strip on the inner wall of the lid body, which allows the first stop strip to be tightly engaged with the first side, thereby preventing the lid from detaching from the bucket body. A first crease line for opening and closing the lid top is provided at the connection between the lid top and the lid body, facilitating repeated opening and closing of the lid top. A limiting strip is provided on the side of the lid top near the lid body, and the outer wall of the limiting strip is tangent to the inner wall of the lid top, allowing the lid top to be tightly engaged with the lid body when closed. A first stop strip is provided on the inner wall of the lid body, which cooperates with the limiting strip. The first stop strip is inclined on the side near the lid top. This design of the first stop strip can resist the lid top and prevent the lid top from being pressed into the lid body by force. This design enables the lid to be repeatedly closed. When the trash can is not in use, the lid tightly closes the bucket body. The airtight lid reduces the spread of odors and prevents garbage from overflowing.
[0017] In a preferred embodiment of this utility model, a retaining strip is formed on the inner wall of the lid between the first and second retaining strips, and a first easy-tear line is formed between the top of the lid and the second retaining strip. When it is necessary to process garbage that is larger than the inner wall space of the paper garbage can, the top of the lid can be torn off using the first easy-tear line, and another garbage can can be inverted and locked into the second retaining strip and the retaining strip. The lid can be used to connect the other garbage can to form a combined garbage can, thereby achieving the purpose of expanding the volume of the garbage can.
[0018] In addition, the bottom of the bin has a second tear line and a second crease line. When the bin lid is used to connect to another trash can, the bottom of the bin is torn open to a fixed length using the second tear line. The torn part is bent along the second crease line to form the lid of the combined trash can, thus achieving the purpose of increasing the volume of the trash can while retaining the lid.
[0019] In a preferred embodiment of this utility model, a pressing plate is provided in the groove at the bottom of the bin. A third fold line is formed on the pressing plate, which cooperates with the second fold line. The pressing plate can slide by utilizing the groove. When the third fold line separates from or overlaps with the second fold line, when separated, the locking part on one side of the pressing plate cooperates with the recess on the bin body to reinforce the position of the second easy-tear line. In this state, the excess part of the pressing plate can be used as a foot pedal for the trash can. When overlapped, the bottom of the bin is torn open in conjunction with the second easy-tear line, forming a disposal opening at the bottom of the bin, thus achieving the purpose of keeping the lid of the trash can.
[0020] In addition, a round hole for connecting the handle can also be provided on the bottom of the bin. The handle is connected to the round hole through the first limiting buckle. At this time, the second easy-tear line is located on the inner wall of the bottom of the bin. This design can also make the bottom of the bin tear open by the second easy-tear line, forming the bottom of the bin into a disposal opening, so as to achieve the purpose of having a lid for the garbage bin combination.
[0021] 4. As a preferred embodiment of this utility model, a first skirt strip is provided on the inner side of the bin near the bottom, and the top surface of the first skirt strip engages with one side of the bottom of the bin. This design can also block the bottom of the bin when the bin is in the "bin lid" state, preventing the bottom of the bin from being pressed into the bin by force. This design can also lock the bottom of the bin when the trash can is not in use, thereby preventing the odor from emanating when the trash can is in use.
[0022] In addition, a second skirt strip is provided on the side of the bottom of the bucket near the body. The outer wall of the second skirt strip is tangent to the inner wall of the bucket body. This design can also help to secure the bottom of the bucket to the body.
[0023] 5. In a preferred embodiment of this utility model, a handle is movably connected through a hole, and both ends of the handle are provided with a second limiting buckle that mates with the hole. The second limiting buckle consists of a curved easy-tear line and a connecting fold line. In use, the curved easy-tear line is bent and inserted into the hole using the connecting fold line, thus enabling the trash can to be equipped with a handle. This design makes the trash can easy to carry and move, and the handle design allows the trash can to be suspended.
[0024] 6. As a preferred embodiment of this utility model, by providing an observation port extending along the height of the bin, with a plastic film attached to the inside of the observation port, the garbage disposal status can be easily checked, avoiding frequent opening of the lid, thereby preventing excessive accumulation and ensuring timely garbage disposal.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0047] Example 1
[0048] like Figures 1-3 As shown, a disposable trash can with a reusable lid is assembled from a body and a lid. The body includes a barrel and a bottom, with a first side edge formed on the barrel. The lid includes a top and a body, with a limiting strip on the side of the top edge near the body. The outer wall of the limiting strip is tangent to the inner wall of the top edge. A first stop strip is provided on the inner wall of the body, cooperating with the limiting strip. The first stop strip has an inclined surface on the side near the top edge. The first side edge of the barrel and the first stop strip on the inner wall of the lid allow the first stop strip to tightly engage with the first side edge, thus preventing the lid from detaching from the barrel. Furthermore, the inclined surface design of the first stop strip not only ensures that the first stop strip tightly engages with the first side edge, but also employs a one-way ratchet anti-retraction principle, achieving easy assembly and making it difficult for the lid to detach from the barrel after assembly. The top and body of the lid are connected by a first crease line for opening and closing the lid. This design guides the lid to move along a fixed trajectory, preventing it from shifting or getting stuck when opening. A limit strip is provided on the side of the lid near the body, with the outer wall of the limit strip tangent to the inner wall of the lid. This design ensures that when the lid is closed, the outer wall of the limit strip is in close contact with the inner wall of the body, thereby improving the effect of preventing odor leakage. The limit strip also acts as a supporting frame for the lid, reducing deformation when the lid is under stress. The limit strip on the inner wall of the body cooperates with the first stop strip, which has an inclined surface on the side near the lid. This design ensures that when the lid is closed to a certain angle, the bottom wall of the limit strip contacts the inclined surface of the first stop strip, preventing the lid from being pressed down excessively through physical blocking.
[0049] Meanwhile, an observation opening extending along the height of the bin is formed on the side wall of the bin. The inside of the observation opening is covered with a plastic film. The amount of garbage in the bin can be directly observed through the observation window at the height of the bin, avoiding frequent opening of the lid, so as to determine in time whether it needs to be cleaned and prevent garbage from overflowing.
[0050] Example 2
[0051] like Figure 4 and Figure 5As shown, a disposable trash can with a reusable lid, differing from Embodiment 1, has a retaining strip formed between the first and second retaining strips on the inner wall of the lid, and a first tear line formed between the lid top and the second retaining strip. When more trash than the inner wall space of the paper trash can needs to be processed, the lid top is torn off along the first tear line, and another trash can is inverted. The first side of the inverted trash can is then secured between the second retaining strip and the retaining strip on the inner wall of the lid. The lid is used to connect the other trash can, and the two trash cans can form a combined trash can, thereby increasing the trash can's volume ratio and processing more trash.
[0052] In addition, the bottom of the bin has a second easy-tear line and a second crease line. When the bin lid is used to connect with another bin to form a combination bin, the bottom of the bin is torn along the second easy-tear line for a fixed length, and the torn part is bent along the second crease line to form the "bin lid" of the combination bin. This achieves the purpose of increasing the volume of the bin while retaining the "bin lid", thus ensuring that odor leakage is prevented while handling more garbage.
[0053] Example 3
[0054] like Figures 6-10 As shown, a disposable waste paper tube with a reusable lid, differing from Embodiment 1, features a third fold line formed on the pressure plate when a foot plate is installed in the groove at the bottom of the tube. The groove allows the foot plate to slide, enabling the third fold line to separate from or overlap with the second fold line, thus achieving different functions: during normal use, when the third fold line separates from the second fold line and is located on the side of the bottom of the tube, a locking piece on one side of the pressure plate engages with a recess on the tube body. This design can increase... The second easy-tear line is fixed in position, and in this state, the excess part of the pressing plate can be used as a foot pedal for fixing the trash can; when the combined trash can is formed, the groove is used to make the pressing plate slide, so that the third fold line coincides with the second fold line, and the bottom of the can is torn along the second easy-tear line for a fixed length. The torn part is bent along the second fold line and the third fold line. The torn part can be opened to form a disposal opening, which can achieve the purpose of keeping the trash can "lid". In this state, the excess part of the pressing plate can form a handle for the "lid".
[0055] In addition, a round hole can be provided at the bottom of the bucket for connecting a handle. The handle is connected to the round hole through a first limiting buckle, such as... Figure 9 At this point, the second tear line is located on the inner wall of the bottom of the bin. This design also allows the bottom of the bin to be torn along the second tear line. The torn part is bent along the second fold line, and the torn part can be opened to form a disposal opening, so as to achieve the purpose of combining the trash cans to form a bin lid.
[0056] Furthermore, a first skirt strip is provided on the inner side of the bin near the bottom, and the top surface of the first skirt strip engages with one side of the bottom of the bin. This design allows the top of the bin to engage with the inner wall of the bottom of the bin when the "lid" is closed at a certain angle, thus physically preventing the "lid" from being pressed down excessively and achieving the purpose of locking the "lid". In addition, a second skirt strip is provided on the bottom of the bin near the body, and the outer wall of the second skirt strip is tangent to the inner wall of the bin. When the "lid" is closed at a certain angle, the outer wall of the second skirt strip contacts the inner wall of the bin, achieving a sealing effect. This design allows the bottom of the bin to be locked tightly into the bin body, achieving a closed design and thus preventing odors from escaping when the bin is in use.
[0057] Example 4
[0058] like Figure 2 and Figure 11 As shown, a disposable trash can with a reusable lid, unlike embodiment 1, has a handle fixedly connected to the trash can through a hole. The handle is deformed by the second limiting buckles at both ends. The second limiting buckles are torn along the curved easy-tear line, bent along the connecting fold line and inserted into the hole of the trash can. Then the second limiting buckles are pressed along the inner wall of the can, so that the handle is fixedly installed on the trash can. The handle design allows the user to lift the trash can by the handle, avoiding touching the dirty outer wall of the can with their hands, making it convenient to empty the trash or change its position. The handle design also allows the trash can to be hung.
