Description

Technical Field

[0001] The present application relates to the technical field of oral cleaning, and in particular to a box assembly. Background Art

[0002] A dental floss box is a small box component that can be used to hold a dental floss roll. The dental floss box can keep the dental floss roll clean. The user can carry the dental floss box conveniently. When dental floss is needed, a predetermined length (e.g., 25 cm or 33 cm) of dental floss is drawn out from the dental floss box. Then the dental floss is supported by fingers and the teeth are cleaned. However, currently dental floss boxes are mainly made of plastic, so they are not environmentally friendly, and thus discarded dental floss boxes pollute the environment. At the same time, the plastic dental floss box itself has high hardness and strong pressure resistance. If environmentally friendly materials (e.g., paper materials) are used to manufacture dental floss with the same structure and replace the plastic dental floss box, it is not easy to achieve the functions of high hardness and strong pressure resistance of the plastic dental floss box. Summary of the invention

[0003] The embodiment of the present application provides a box assembly that has good environmental performance, so that discarded box assemblies are not easy to pollute the environment, and meet the actual required hardness and pressure resistance.

Therefore, during the daily repeated use of the box assembly of the embodiment of the present application, the box assembly is not prone to deformation, flattening and other problems. The box assembly of the embodiment of the present application uses environmentally friendly materials, so it is not easy to pollute the environment after being discarded.

[0052] In order to better understand the present application, the box assembly of the embodiment of the present application is described below with reference to the accompanying drawings.

[0053] Figure 1 The structure of the box assembly 10 is schematically shown. Figure 2 The structure of the box assembly 10 is schematically shown. Figure 3 The partial structure of the box assembly 10 in the opened state is schematically shown. Figure 4 The partial structure of the paper support 50 of the cover member 40 is schematically shown. Figure 5 A partial exploded structure of the box assembly 10 is schematically shown. Figure 6 The partially exploded structure of the box assembly 10 containing the dental floss roll 300 is schematically shown.

[0054] See also Figures 1 to 6 As shown, the embodiment of the present application provides a box assembly 10 , which includes a paper bottom box 20 , a paper dental floss reel 30 and a cover component 40 .

[0055] The paper bottom box 20 includes a first accommodating cavity 201. The paper dental floss reel 30 is disposed in the first accommodating cavity 201. The paper dental floss reel 30 is used to support the dental floss roll 300.

[0056] The cover component 40 includes a paper upper support 50, a paper cover body 60 and a wire cutter 70. At least part of the paper upper support 50 is located in the first accommodating cavity 201. The paper upper support 50 and the paper bottom box 20 are detachably connected only by friction fit. The paper upper support 50 includes a second accommodating cavity 501 and a wire outlet opening 502. The wire outlet opening 502 communicates the first accommodating cavity 201 with the second accommodating cavity 501. The paper cover body 60 is hinged to the paper upper support 50. The paper cover body 60 is flipped relative to the paper upper support 50 to switch between an open position and a cover closed position. The wire cutter 70 is arranged on the paper cover body 60.

[0057] When the paper cover 60 is in the closed position, the paper cover 60 covers the second accommodating cavity 501 and the wire outlet opening 502, and the wire cutter 70 and at least part of the paper cover 60 are located in the second accommodating cavity 501. The paper cover 60 and the paper upper support 50 are connected only by friction fit. When the paper cover 60 is in the open position, the wire outlet opening 502 and the wire cutter 70 are in an exposed state.

[0058] In the embodiment of the present application, the process of the user using the box assembly 10 can be that the user holds the paper bottom box 20 and opens the paper cover body 60 in the cover component 40. The user pinches the dental floss drawn out from the outlet opening 502 of the paper upper support 50 with fingers, and then pulls the dental floss to extract a predetermined length (for example, 25 cm or 33 cm) of dental floss. The dental floss is placed at the wire cutter 70 and cut. The paper cover body 60 is closed and the box assembly 10 is put down. The user can use fingers to shape the dental floss and use fingers to support the dental floss. The fingers drive the dental floss to clean the teeth. After cleaning, the dental floss is discarded. The material of the dental floss may include nylon thread, silk thread or polyester thread.

[0059] After the dental floss roll 300 in the box assembly 10 is used up, the cover member 40 can be separated and removed from the paper bottom box 20 as a whole. Then, the paper dental floss reel 30 is pulled up to take it out of the paper bottom box 20. The dental floss reel 300 is reinstalled on the paper dental floss reel 30. The paper dental floss reel and the dental floss reel 300 are then loaded into the first accommodating chamber 201 of the paper bottom box 20. The thread end of the dental floss reel 300 is passed through the thread outlet opening 502 of the paper upper support 50, and the paper upper support 50 is installed on the paper bottom box 20. Finally, the paper cover body 60 is turned over to the cover-closed position so that the box assembly 10 can continue to be reused. Therefore, in each embodiment of the present application, not only the material itself is an environmentally friendly material, but also the use method is an environmentally friendly form.

[0060] The paper bottom box 20 of the embodiment of the present application is a box body that is often in contact with the user's hands. The paper bottom box 20 can protect the paper upper support 50, so that the user's fingers are not easy to touch the paper upper support 50, reducing the possibility of the fingers carrying bacteria or dirt to contaminate the paper upper support 50. At least part of the paper upper support 50 is located in the first accommodating cavity 201. The part of the paper upper support 50 located on the paper bottom box 20 is detachably connected to the paper bottom box 20 only by friction fit. The friction fit connection method belongs to interference fit.

[0061] The cover member 40 is connected to the paper bottom box 20 as a whole through the paper upper support 50. When the paper upper support 50 needs to be pulled out from the paper bottom box 20 to separate the cover member 40 and the paper bottom box 20, a pulling force needs to be applied to the paper upper support 50 to overcome the friction between the paper upper support 50 and the paper bottom box 20, so as to separate the paper upper support 50 from the paper bottom box 20. When the paper upper support 50 needs to be installed into the paper bottom box 20 to connect the cover member 40 and the paper bottom box 20, a pressure needs to be applied to the paper upper support 50 to overcome the friction between the paper upper support 50 and the paper bottom box 20, so as to assemble the paper upper support 50 and the paper bottom box 20.

[0062] The paper upper support 50 and the paper bottom box 20 are detachably connected only by friction fit, so that no additional connecting parts are required between the paper upper support 50 and the paper bottom box 20. On the one hand, the number of parts of the box assembly 10 as a whole can be reduced, and the assembly process can be reduced. On the other hand, the disassembly and assembly process between the paper upper support 50 and the paper bottom box 20 is convenient and easy to operate, which is conducive to reducing the difficulty of reusing the box assembly 10 and replacing the dental floss roll 300, thereby improving the usability of the box assembly 10.

[0063] The paper dental floss reel 30 is located below the paper upper support 50. The paper dental floss reel 30 is used to support the dental floss roll 300. The dental floss roll 300 is rotatably connected to the paper dental floss reel 30. When the user pulls the dental floss through the outlet opening 502 of the paper upper support 50, the dental floss roll 300 rotates on the paper dental floss reel 30. The dental floss roll 300 itself has a central plug hole. When the dental floss roll 300 is replaced, the paper dental floss reel 30 is inserted into the central plug hole of the dental floss roll 300.

[0064] The wire cutter 70 is disposed on the paper cover 60. The box assembly 10 is provided with the wire cutter 70 so that the user can conveniently use the wire cutter 70 to cut the dental floss drawn out from the outlet opening 502, so the user does not need to carry an additional tool for cutting the dental floss, thereby improving the convenience of using the box assembly 10. Exemplarily, the material of the wire cutter 70 may include metal materials such as steel and iron.

[0065] The paper cover 60 is connected to the paper upper support 50, so when the paper cover 60 is in the open state, there is no need to remove the paper cover 60 and place it in other areas, reducing the possibility of losing the paper cover 60. At the same time, the paper cover 60 can be opened or closed by simply flipping the paper cover 60, which is conducive to improving the convenience of operation of the paper cover 60 and improving the usability of the box assembly 10.

[0066] When the paper cover 60 is in the closed position, the paper cover 60 covers the second accommodating cavity 501. The wire cutter 70 is located in the second accommodating cavity 501. The paper cover 60 can protect the paper upper support 50 and the wire cutter 70, reducing the possibility of the paper upper support 50 and the wire cutter 70 being contaminated. When the paper cover 60 is in the open position, the paper cover 60 opens the second accommodating cavity 501. The wire outlet opening 502 of the paper upper support 50 and the wire cutter 70 on the paper cover 60 are in an exposed state, which is convenient for the user to pull and cut the dental floss.

[0067] At least part of the paper cover 60 is located in the second accommodating cavity 501. The part of the paper cover 60 located in the second accommodating cavity 501 is connected to the paper upper support 50 only by friction fit.

[0068] When the paper cover 60 needs to be pulled out from the paper upper support 50 to open the paper cover 60, a turning torque needs to be applied to the paper cover 60 to overcome the friction between the paper upper support 50 and the paper cover 60, thereby separating the paper upper support 50 from the paper cover 60. When the paper cover 60 needs to be connected to the paper upper support 50 to close the paper cover 60, pressure needs to be applied to the paper cover 60 to overcome the friction between the paper upper support 50 and the paper cover 60, thereby connecting the paper cover 60 to the paper upper support 50.

[0069] The paper upper support 50 and the paper cover 60 are connected only by friction fit, so that no additional connecting parts are required between the paper upper support 50 and the paper cover 60. Therefore, on the one hand, the number of parts of the box assembly 10 as a whole can be reduced, and the assembly process can be reduced. On the other hand, the disassembly and assembly process between the paper upper support 50 and the paper cover 60 is convenient and easy to operate, which is conducive to reducing the difficulty of reusing the box assembly 10 and replacing the dental floss roll 300, thereby improving the usability of the box assembly 10.

[0070] The box assembly 10 of the embodiment of the present application includes a paper bottom box 20, a paper dental floss reel 30 and a cover component 40, so that the number of parts used in the box assembly 10 itself is relatively small, which is conducive to reducing the assembly process and material usage of the box assembly 10, thereby helping to reduce production costs, while improving the ease of operation of the dental floss reel 300 replacement process and improving user satisfaction. The paper bottom box 20, the paper dental floss reel 30 and the cover component 40 can support each other, thereby ensuring that the overall structural strength of the assembled box assembly 10 is relatively large, the pressure resistance is high, and after the dental floss reel 300 is installed, it has the above-mentioned cleaning characteristics, and is not prone to deformation and flattening. The paper bottom box 20 and the paper upper support 50 are detachably connected only by friction fit, which is convenient for disassembly and assembly between the paper bottom box 20 and the cover component 40, reducing the difficulty of disassembly and assembly operations and improving convenience of use. The paper cover 60 and the paper upper support 50 in the cover part 40 are connected only by friction fit, which facilitates the connection and separation between the paper cover 60 and the paper upper support 50, reduces the difficulty of opening and closing the paper cover 60, and improves the convenience of use. The paper cover 60 can protect the paper upper support 50 and the wire cutter 70, and reduce the possibility of contamination of the paper upper support 50 and the wire cutter 70. In the box assembly 10 of the embodiment of the present application, the paper bottom box 20, the paper dental floss reel 30, the paper upper support 50 and the paper cover 60 are all made of paper materials, so that they have good environmental protection, so that the discarded box assembly 10 is not easy to pollute the environment, and can also be recycled and reused, meeting environmental protection requirements.

[0071] In some practicable embodiments, the paper bottom box 20, the paper dental floss reel 30, the paper upper support 50 and the paper cover 60 can all be manufactured by using a pulp molding process.

[0072] In some achievable ways, the friction between the paper upper support 50 and the paper bottom box 20 is greater than the friction between the paper cover 60 and the paper upper support 50. When the paper cover 60 needs to be flipped from the closed position to the open position, the force applied to the paper cover 60 can separate the paper cover 60 and the paper upper support 50, but the force is smaller than the friction between the paper upper support 50 and the paper bottom box 20, so that the force will not cause the paper upper support 50 to separate from the paper bottom box 20, reducing the possibility of separation of the paper upper support 50 and the paper bottom box 20 when flipping the paper cover 60.

[0073] In some feasible embodiments, the paper bottom box 20 is an integrally formed structure, which is beneficial to ensure that the paper bottom box 20 itself has good structural strength, and can also help reduce the difficulty of processing the paper bottom box 20.

[0074] In some achievable ways, Figure 7 The partial structure of the cover member 40 is schematically shown. Figure 7 As shown, the paper upper support 50 and the paper cover 60 are an integrally formed structure, so that the paper upper support 50 and the paper cover 60 do not need to be processed separately and then hinged using connectors, which helps to reduce the difficulty of processing and assembling the cover component 40.

[0075] The paper upper support 50 and the paper cover 60 can be integrally formed by using a pulp molding process. After the paper upper support 50 and the paper cover 60 are formed, a guide indentation 100 is provided between the paper upper support 50 and the paper cover 60, so that the paper cover 60 can be turned over relative to the paper upper support 50 at the guide indentation 100. The paper upper support 50 and the paper cover 60 are hinged at the guide indentation 100.

[0076] In some examples, the cover component 40 is provided with a plurality of spaced through holes 200 in the area corresponding to the guide indentation 100 to remove part of the material, thereby facilitating reducing the area of ​​the connection region between the paper cover body 60 and the paper upper support 50, reducing the flipping torque required to flip the paper cover body 60, and facilitating the user to flip the paper cover body 60 with relatively small force.

[0077] In some possible implementations, see Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the paper upper support 50 includes a first body 51 and a first flange 52. The first body 51 is located in the first accommodating cavity 201 of the paper bottom box 20. The first body 51 and the paper bottom box 20 are detachably connected only by friction fit. The first body 51 is provided with a second accommodating cavity 501 and a wire outlet opening 502. The paper cover 60 is hinged to the first flange 52.

[0078] A first flange 52 is provided at the opening of the first body 51. When the first body 51 of the paper upper support 50 is pressed into the first accommodating cavity 201 of the paper bottom box 20, after the first body 51 is pressed into a predetermined depth, the first flange 52 contacts the paper bottom box 20, thereby limiting the first body 51 from further pressing into the first accommodating cavity 201. Therefore, the first flange 52 can be used to limit and constrain the first body 51, so as to ensure that the first body 51 is accurately pressed into the paper bottom box 20 to a predetermined depth, reduce the difficulty of assembling the paper upper support 50 and the paper bottom box 20, and reduce the possibility that the paper upper support 50 is not constrained and is pressed into the paper bottom box 20 as a whole, thereby causing difficulty in removing the paper upper support 50.

[0079] In some examples, the smoothness of the outer surface of the paper bottom box 20 is greater than the smoothness of the inner surface of the paper bottom box 20, so that when the user touches the outer surface of the paper bottom box 20, it can have a good touch. The outer surface of the paper bottom box 20 is relatively smoother. The relatively rough setting of the inner surface of the paper bottom box 20 is conducive to increasing the friction between the first body 51 and the paper bottom box 20, and improving the connection stability between the paper upper support 50 and the paper bottom box 20.

[0080] Exemplarily, the surface of the first body 51 facing the paper bottom box 20 is a rough surface, which is beneficial to further increase the friction between the first body 51 and the paper bottom box 20 and enhance the connection stability between the paper upper support 50 and the paper bottom box 20.

[0081] In some examples, the wire outlet opening 502 in the paper upper support 50 may be disposed at the bottom of the second accommodating cavity 501 .

[0082] For some examples, see Figure 7 As shown, the paper cover 60 includes a second body 61 and a second flange 62. The thread cutter 70 is disposed on the second body 61. The first flange 52 and the second flange 62 are hinged. When the paper cover 60 is in the closed position, the first flange 52 of the paper upper support 50 and the second flange 62 of the paper cover 60 are stacked, and the second body 61 of the paper cover 60 is located in the second accommodating cavity 501 of the paper upper support 50. The second body 61 of the paper cover 60 is connected to the paper upper support 50 only by friction fit.

[0083] A second flange 62 is provided at the opening of the second body 61. When the second body 61 of the paper cover 60 is pressed into the second accommodating cavity 501 of the paper upper support 50, after the second body 61 is pressed into a predetermined depth, the second flange 62 contacts the first flange 52 of the paper upper support 50, thereby limiting the second body 61 from further pressing into the second accommodating cavity 501. Therefore, the second flange 62 can be used to limit and constrain the second body 61 to ensure that the second body 61 is accurately pressed into the paper upper support 50 to a predetermined depth, reduce the difficulty of operating the paper cover 60 during the closing process, and reduce the possibility that the paper cover 60 is not constrained and is pressed into the paper upper support 50 as a whole, causing the paper cover 60 to be deformed or difficult to pull out.

[0084] When the paper cover 60 is in the closed position, there is a gap between the second body 61 and the bottom of the second accommodating cavity 501 to prevent the wire cutter 70 from contacting the paper upper support 50. The thread end of the dental floss roll 300 and the wire cutter 70 can be located in the gap.

[0085] In some examples, the wire cutter 70 may be disposed at the bottom of the second body 61. The wire cutter 70 may be bonded to the second body 61. Exemplarily, the wire cutter 70 may be bonded to the second body 61 using adhesive or double-sided tape.

[0086] In some examples, Figure 8 Schematically shows a partial cross-sectional structure of the cover member 40. Figure 7 and Figure 8 As shown, the second body 61 has an escape opening 611. The wire cutter 70 includes a first clip 71, a connecting piece 72, a second clip 73 and a cutting knife 74. The connecting piece 72 connects the first clip 71 and the second clip 73. The connecting piece 72 is inserted into the escape opening 611. The wire cutter 70 is clamped to the second body 61 by the first clip 71 and the second clip 73. The first clip 71 is located on the side of the second body 61 facing the paper upper support 50. The first clip 71 is arranged facing the paper upper support 50. The second clip 73 is located on the side of the second body 61 facing away from the paper upper support 50. The first clip 71 is provided with a cutting knife 74. The cutting knife 74 is used to cut the dental floss.

[0087] The wire cutter 70 is clamped on the second body 61 by the first clip 71 and the second clip 73 to achieve the connection and fixation between the wire cutter 70 and the second body 61, so that no additional connecting parts (such as adhesives) are required between the wire cutter 70 and the second body 61, which is beneficial to reducing the number of parts of the box assembly 10 as a whole, and at the same time, it is beneficial to improve the environmental protection of the box assembly 10.

[0088] The assembly process of the wire cutter 70 and the second body 61 may be to pass the second clip 73 from one side of the second body 61 through the avoidance opening 611 of the second body 61, and then continue to push the wire cutter 70, the second clip 73 passes through the avoidance opening 611 and enters the other side of the second body 61, and the connecting piece 72 is inserted into the avoidance opening 611. Then, the first clip 71 is released, so that the first clip 71, the connecting piece 72 and the second clip 73 return to the initial state. The first clip 71 and the second clip 73 clamp the second body 61.

[0089] For some examples, see Figure 7 As shown, the second body 61 has a dental floss fixing portion 612. The dental floss fixing portion 612 is spaced apart from the thread cutter 70.

[0090] The dental floss passing through the thread outlet opening 502 can be fixed on the dental floss fixing portion 612, which reduces the possibility of knotting and entanglement due to the unconstrained dental floss, and also reduces the possibility of the dental floss accidentally being retracted into the first accommodating cavity 201. Exemplarily, there is a gap between the dental floss fixing portion 612 and the second body 61. The dental floss can pass through the gap, and the dental floss fixing portion 612 can press the dental floss.

[0091] In some examples, Fig. 9 The partial cross-sectional structure of the box assembly 10 is schematically shown. Figure 6 and Fig. 9As shown, the cover component 40 includes a paper cover plate 80. The second body 61 has a third accommodating cavity 601. The opening of the third accommodating cavity 601 faces away from the paper upper support 50. The paper cover plate 80 is connected to the paper cover body 60. The paper cover plate 80 covers the third accommodating cavity 601.

[0092] The way in which the second body 61 is provided with the third accommodating cavity 601 can, on the one hand, help the second body 61 to reduce the amount of material used and reduce the processing cost. On the other hand, when the paper cover 80 is formed by the pulp molding process, it is conducive to demolding the paper cover 80 and reduces the processing difficulty of the paper cover 80.

[0093] The paper cover plate 80 can cover the third accommodating cavity 601 of the paper cover body 60. On the one hand, it can ensure that the overall appearance of the cover component 40 is neat and beautiful, and enhance the overall aesthetics of the cover component 40. On the other hand, it can reduce the possibility of impurities and dirt entering the third accommodating cavity 601 and accumulating in the third accommodating cavity 601, and ensure that the cover component 40 has good cleanliness.

[0094] Exemplarily, the paper cover plate 80 can be bonded to the surface of the second flange 62 of the paper cover body 60 that faces away from the paper upper support 50. For example, the paper cover plate 80 can be bonded to the second flange 62 using adhesive or double-sided tape.

[0095] In some examples, Fig.10 The partial cross-sectional structure of the box assembly 10 is schematically shown. Figure 5 , Figure 6 and Fig.10 As shown, the paper dental floss reel 30 includes a transverse shaft portion 31 and a vertical shaft portion 32. The transverse shaft portion 31 is used to support the dental floss reel 300. Both ends of the transverse shaft portion 31 are respectively overlapped with the paper bottom box 20. Two vertical shaft portions 32 are arranged at intervals on the transverse shaft portion 31. The vertical shaft portion 32 extends toward the paper upper support 50. When the paper upper support 50 is pressed into the paper bottom box 20 to a predetermined depth, the first body 51 of the paper upper support 50 presses against the vertical shaft portion 32 to fix the paper dental floss reel 30, which is conducive to preventing the paper dental floss reel 30 from being loose and shaking.

[0096] The vertical shaft portion 32 of the paper dental floss reel 30 can be bent relative to the horizontal shaft portion 31. After the paper dental floss reel 30 is pressed into the paper bottom box 20, the vertical shaft portion 32 has an elastic restoring force. Under the action of its own elastic restoring force, the vertical shaft portion 32 can be stably pressed against the inner surface of the paper bottom box 20 to prevent the paper dental floss reel 30 from being loose or shaking.

[0097] Exemplarily, the paper dental floss reel 30 can be formed by bending a paper tube with an outer diameter of 5 millimeters (mm) and a wall thickness of 1.5 mm, which facilitates the production of the paper dental floss reel 30 .

[0098] When it is necessary to take out the paper floss reel 30 from the paper bottom box 20, the paper floss reel 30 can be taken out from the paper bottom box 20 by pulling the transverse shaft 31 to apply tension to the paper floss reel 30. When replacing the dental floss reel 300, one of the vertical shafts 32 is passed through the central insertion hole of the dental floss reel 300, and the paper floss reel 30 is continuously moved until the transverse shaft 31 passes through the central insertion hole of the dental floss reel 300, and the paper floss reel 30 is stopped. Then, the paper floss reel 30 with the dental floss reel 300 is pressed back into the paper bottom box 20.

[0099] In some examples, Fig.11 The partial cross-sectional structure of the paper bottom box 20 is schematically shown. Fig.10 and Fig.11 As shown, the paper bottom box 20 includes two first grooves 202 arranged at intervals. The first groove 202 on the paper bottom box 20 is connected to the first accommodating chamber 201. The first groove 202 has a bottom wall 2021. There is a distance between the bottom wall 2021 of the first groove 202 and the bottom surface 2011 of the first accommodating chamber 201. The transverse shaft portion 31 of the paper dental floss reel 30 has two opposite ends. The two ends of the transverse shaft portion 31 are respectively arranged corresponding to the two first grooves 202. The two ends of the transverse shaft portion 31 are respectively overlapped with the bottom walls 2021 of the two first grooves 202. At least part of the vertical shaft portion 32 is located in the first groove 202.

[0100] When the paper floss reel 30 is loaded into the paper base box 20, the first groove 202 can provide positioning and guidance for the paper floss reel 30, so as to accurately and quickly press the paper floss reel 30 into the paper base box 20, thereby reducing the difficulty of assembling the paper floss reel 30 and the paper base box 20.

[0101] The bottom wall 2021 of the first groove 202 can limit the paper dental floss reel 30. After the paper dental floss reel 30 is pressed into the paper bottom box 20 to a predetermined depth, the paper dental floss reel 30 contacts the bottom wall 2021 of the first groove 202, thereby limiting the paper dental floss reel 30 from being further pressed in. Therefore, the bottom wall 2021 of the first groove 202 can be used to limit and constrain the paper dental floss reel 30 to ensure that the paper dental floss reel 30 is accurately pressed into the paper bottom box 20 to a predetermined depth, reduce the difficulty of assembling the paper dental floss reel 30 and the paper bottom box 20, and reduce the possibility that the paper dental floss reel 30 is pressed into the paper bottom box 20 to an excessive depth due to the unconstrained paper dental floss reel 30 and the contact between the dental floss reel 30 and the paper bottom box 20.

[0102] The spacing between the bottom wall 2021 of the first groove 202 and the bottom surface 2011 of the first accommodating chamber 201 needs to meet the requirement that after the paper dental floss reel 30 is installed in place, the dental floss roll 300 on the paper dental floss reel 30 does not contact the paper bottom box 20, ensuring that there is a gap between the dental floss roll 300 and the paper bottom box 20 to prevent scratches between the dental floss roll 300 and the paper bottom box 20 when the dental floss roll 300 rotates.

[0103] The vertical shaft portion 32 is located in the first groove 202, so that the paper bottom box 20 limits the vertical shaft portion 32, so that the paper dental floss reel 30 will not rotate relative to the paper bottom box 20 during the process of pulling the dental floss.

[0104] For some examples, see Figure 5 , Fig.10 and Fig.11 As shown, the paper bottom box 20 includes a third body 21 and a third flange 22. The third body 21 is provided with a first accommodating cavity 201. The first groove 202 is provided in the third body 21. The first flange 52 of the paper upper support 50 and the third flange 22 of the paper bottom box 20 are stacked.

[0105] The third flange 22 is provided at the opening of the third body 21. When the first body 51 of the paper upper support 50 is pressed into the first accommodating cavity 201 of the paper bottom box 20, after the first body 51 is pressed into a predetermined depth, the first flange 52 of the paper upper support 50 contacts the third flange 22 of the paper bottom box 20, thereby limiting the first body 51 from being further pressed into the first accommodating cavity 201. The first flange 52 of the paper upper support 50 and the third flange 22 of the paper bottom box 20 are stacked in such a way that the first flange 52 and the third flange 22 can support each other, thereby reducing the possibility of the first flange 52 and the third flange 22 being folded and deformed by external forces.

[0106] For some examples, see Fig. 9 and Fig.11 As shown, the bottom of the third body 21 may be arc-shaped, so as to facilitate gripping of the paper bottom box 20 .

[0107] In some examples, Fig.12 The structure of the box assembly 10 is schematically shown. Figure 5 , Fig.10 and Fig.12 As shown, a portion of the third body 21 protrudes to form a first rib 211. The first rib 211 is disposed corresponding to the first groove 202.

[0108] When the paper bottom box 20 is processed, the first convex rib 211 and the first groove 202 can be processed and formed in the same process, which reduces the processing steps and reduces the processing difficulty of the paper bottom box 20.

[0109] The first convex rib 211 can be used as a reinforcement to improve the structural strength of the paper bottom box 20. The paper bottom box 20 with the first convex rib 211 has relatively high overall structural strength and high pressure resistance, so that the paper bottom box 20 as a whole is not prone to deformation or collapse when subjected to external force.

[0110] The paper bottom box 20 is an integrally formed structure. The method of directly forming the first convex rib 211 on the third body 21 replaces the method of separately processing and manufacturing the third body 21 and the first convex rib 211 and then assembling them, thereby eliminating the process of separately processing the first convex rib 211 and bonding the first convex rib 211 to the third body 21 by an adhesive, and also eliminating the use of adhesives, thereby improving the environmental friendliness of the box assembly 10.

[0111] For some examples, see Figure 5 , Figure 7 and Fig.10 As shown, the paper floss support 50 includes a first body 51. A portion of the first body 51 protrudes to form a second convex rib 511. The second convex rib 511 is inserted into the first groove 202. The second convex rib 511 presses against the vertical shaft portion 32 of the paper dental floss reel 30.

[0112] The second convex rib 511 can be used as a reinforcement to improve the structural strength of the paper support 50. The paper support 50 with the second convex rib 511 has a relatively high overall structural strength and high pressure resistance, so that the paper support 50 as a whole is not easily deformed or collapsed when subjected to external forces.

[0113] The paper upper support 50 is an integrally formed structure. The second convex rib 511 is directly formed on the first body 51, which replaces the method of separately processing and manufacturing the first body 51 and the second convex rib 511 and then assembling them, thereby eliminating the process of separately processing the second convex rib 511 and bonding the second convex rib 511 to the first body 51 by adhesive, and also eliminating the use of adhesive, thereby improving the environmental friendliness of the box assembly 10.

[0114] During the assembly process of the paper upper support 50 and the paper bottom box 20, the second convex rib 511 of the paper upper support 50 is aligned with the first groove 202 inserted into the paper bottom box 20, and then pressure is applied to the paper upper support 50 to press the paper upper support 50 into the paper bottom box 20. The second convex rib 511 and the first groove 202 can form a positioning structure, which is convenient for accurately and quickly assembling the paper upper support 50 and the paper bottom box 20, and can also reduce the possibility of the paper upper support 50 being stuck in the paper bottom box 20 due to positional deviation during the pressing process of the paper upper support 50, thereby improving the convenience and ease of use of the paper upper support 50 in disassembly and assembly.

[0115] For some examples, see Figure 5 , Figure 7 and Fig.10 As shown, the first body 51 of the paper support 50 is provided with a second groove 503 corresponding to the second convex rib 511. The second groove 503 is communicated with the second accommodating cavity 501.

[0116] When processing the paper upper support 50 , the second convex rib 511 and the second groove 503 can be processed and formed in the same process, thereby reducing the processing steps and lowering the processing difficulty of the paper bottom box 20 .

[0117] The manner in which the second groove 503 is provided in the first body 51 can, on the one hand, help reduce the material usage of the first body 51 and reduce the processing cost. On the other hand, when the paper upper support 50 is formed by the pulp molding process, it is conducive to demolding the paper upper support 50 and reduces the processing difficulty of the paper upper support 50.

[0118] For some examples, see Figure 4 , Figure 5 and Fig.10 As shown, the first flange 52 of the paper upper support 50 includes a first notch 521. The third flange 22 of the paper bottom box 20 includes a second notch 221. The first notch 521 is arranged corresponding to the second notch 221. When the paper cover 60 is in the closed position, the first flange 52, the second flange 62 and the third flange 22 are stacked, and a portion of the second flange 62 is exposed in the first notch 521.

[0119] The portion of the second flange 62 exposed in the first notch 521 can be used as a finger position for opening the paper cover 60. The user can operate the box assembly 10 with one hand. The user's finger can be placed on the portion of the second flange 62 exposed in the first notch 521, and then a turning moment is applied to the paper cover 60 to separate the paper cover 60 and the paper upper support 50, and the paper cover 60 is placed in an open position, thereby improving the convenience of using the box assembly 10. For example, the user's palm can hold the paper bottom box 20, and use the thumb to apply a turning moment to the second flange 62 to open or close the paper cover 60.

[0120] Exemplarily, the first flange 52 of the paper upper support 50 has an edge away from the hinged position of the paper cover 60 and the paper upper support 50, and a first notch 521 is provided on the edge. The third flange 22 of the paper bottom box 20 has an edge away from the hinged position of the paper cover 60 and the paper upper support 50, and a second notch 221 is provided on the edge. Exemplarily, the shape of the first notch 521 can be the same as the shape of the second notch 221.

[0121] In some achievable embodiments, at least one of the paper base box 20, the paper dental floss reel 30, the paper upper support 50, and the paper cover 60 is solidified and formed using raw materials including bamboo pulp and bagasse pulp, wherein the total mass proportion of the bamboo pulp in the raw materials is 35%, and the total mass proportion of the bagasse pulp in the raw materials is 65%.

[0122] Bamboo pulp includes bamboo fiber. The fiber structure of bamboo fiber is compact and the fiber length is relatively long. Bamboo fiber has good mechanical properties such as elastic modulus and tensile strength. Bamboo fiber can help improve the tensile strength of processed paper molded parts, thereby helping to improve the elasticity of paper molded parts. When paper molded parts including bamboo fiber are subjected to force, they can be deformed and are not prone to cracking. Bagasse pulp includes bagasse. The fibers of bagasse are relatively short and have good flexibility. The method in which the total mass of bamboo pulp in the raw material accounts for 35%, and the total mass of bagasse pulp in the raw material accounts for 65%, can help ensure that the paper molded parts themselves have high strength, elasticity and flexibility.

[0123] The paper upper support 50 is detachably connected to the paper bottom box 20 by friction fit. At least one of the paper upper support 50 and the paper bottom box 20 is solidified and formed using raw materials including bamboo pulp and bagasse pulp, so that at least one of the paper upper support 50 and the paper bottom box 20 has elasticity, so that during the process of the paper upper support 50 being pressed into the paper bottom box 20, at least one of the paper upper support 50 and the paper bottom box 20 can be elastically deformed. After the paper upper support 50 is pressed into the paper bottom box 20, under the action of the elastic restoring force, the paper upper support 50 and the paper bottom box 20 can maintain a mutually pressed state to maintain a stable connection state, so that the paper upper support 50 and the paper bottom box 20 are not easy to separate.

[0124] When the paper cover 60 is in the cover-closed position, a portion of the paper cover 60 is located in the second accommodating cavity 501 of the paper upper support 50. The paper cover 60 and the paper upper support 50 are connected by friction fit. At least one of the paper cover 60 and the paper upper support 50 is solidified and formed using raw materials including bamboo pulp and bagasse pulp, so that at least one of the paper cover 60 and the paper upper support 50 has elasticity. When the paper cover 60 is in the cover-closed position, at least one of the paper cover 60 and the paper upper support 50 can be elastically deformed. Under the action of the elastic restoring force between the paper cover 60 and the paper upper support 50, the paper cover 60 and the paper upper support 50 can maintain a mutually pressed state to maintain a stable connection state, so that the paper cover 60 is not easy to accidentally flip open.

[0125] In some examples, the paper bottom box 20, the paper dental floss reel 30, the paper upper support 50, and the paper cover 60 are all solidified and formed using raw materials including bamboo pulp and bagasse pulp.

[0126] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
