Description

Technical Field

[0001] The present invention relates to a waste container, and more particularly to a waste container capable of preventing odor from being diffused to the outside through an insertion port opened when discarding waste. Background Art

[0002] Garbage generated in daily life is collected on dates determined by each local government, but must be stored in personal trash cans until collection. The maximum storage period for household waste, such as kitchen waste, is approximately three to four days. However, as kitchen waste gradually decomposes, it is likely to produce odors, especially during summer months.

[0003] However, there are few trash cans with a deodorizing function, and many trash cans are designed to store trash only for a period of time. Therefore, in many cases, the smell of food waste, etc., leaks from the trash can during storage, and this often causes discomfort.

[0004] To solve this problem, a "trash can" has been disclosed, in which deodorant is sprayed into the main body using the pressing force generated when the upper lid is closed, as disclosed in Patent Document 1. Therefore, the deodorant is sprayed every time the upper lid is closed, thereby reducing the generation of odor in the trash can.

[0008] Technical issues

[0009] However, in the trash can described in Patent Document 1, in order to spray the deodorant by closing the upper cover of the main body, the upper cover needs to be opened widely as a preliminary step. Therefore, when the upper cover is opened, the entire opening of the trash can main body is exposed, and the odor inside the main body is easily diffused to the outside.

[0010] The present invention has been made in view of the above points, and an object of the present invention is to provide a waste container capable of preventing odor from being diffused to the outside from an insertion port opened when discarding waste.

[0011] Solution to the problem

[0012] In order to solve the above-mentioned problems, a waste container according to the present invention includes: a container body having a predetermined opening; and a closing body configured to be attachable to the container body to substantially close the opening, the closing body including an insertion portion and an opening and closing portion. When the closing body is attached to the container body, the insertion portion is inserted into the interior from the opening and has a hollow structure. The hollow structure has a predetermined insertion port. When an opening and closing member advances and retreats along a guide portion, the opening and closing portion can open and close the insertion port. When the insertion port is open, the opening and closing member is accommodated in the insertion portion.

[0013] Here, because the closing body includes an opening and closing portion that can open and close the insertion opening via an opening and closing member that advances and retracts along the guide portion, when the insertion opening is opened and closed, the opening and closing member advances and retracts along a defined path (i.e., the guide portion), enabling stable advancement and retraction. Furthermore, because the opening and closing member advances and retracts stably at the insertion opening, significant disturbances in the air surrounding the insertion opening can be prevented.

[0014] Furthermore, the closed body includes an insertion portion having a hollow structure with a predetermined insertion opening, and an opening and closing portion that is received within the insertion portion when the opening and closing member opens the insertion opening. Therefore, when the opening and closing member moves in and out of the insertion portion to open and close the insertion opening, any disturbance of air within the insertion portion does not cause disturbance to the outside of the insertion portion, nor does it cause disturbance to the air because the inside of the insertion portion, which houses the opening and closing member, is separated from the outside of the insertion portion by the member forming the insertion portion.

[0015] Furthermore, the opening and closing member need not be entirely contained within the insert. For example, a portion of the opening and closing member may be contained within the insert. In this case, as with the case where the entire opening and closing member is contained during advancement and retraction, any disturbance of the air within the insert will not cause disturbances outside the insert, nor will it cause disturbances to the air.

[0016] Furthermore, by the container body having the predetermined opening and the closing body configured to be attachable to the container body to substantially close the opening, it is possible to prevent odor from leaking from the inside of the container body to the outside through the opening.

[0017] In addition, since the container body and the closed body allow the insertion part to enter the container body when attached, wherein the container body has a predetermined opening and the closed body includes an insertion part, which is inserted into the interior from the opening when the closed body is attached to the container body, this provides stability and the closed body can be firmly attached to the container body.

[0018] When the insert is made of an airtight material, the interior of the insert, which houses the opening and closing member, is separated from the exterior of the insert by the airtight member forming the insert. Therefore, even if the air inside the insert is slightly disturbed by the opening and closing of the insertion port, the exterior of the insert is further protected from air disturbances. Furthermore, even when the insert is exposed to the exterior of the container body, odors from the interior of the container body are prevented from leaking through the insert.

[0019] In addition, when the opening and closing member is composed of a pair of opening and closing members that advance and retreat in opposite directions to each other, and the edge portions of the opening and closing members facing each other are formed to be assembled, the moving distance for closing the insertion port is shared by the two opening and closing members, the time required for opening and closing the insertion port can be shortened, and when the insertion port is closed by the opening and closing members, the edge portions are assembled, thereby preventing the odor inside the container body from leaking to the outside.

[0020] Furthermore, when the closed body includes a deodorizing portion provided near the insertion port, odors rising from the interior of the container body can be effectively removed.

[0021] When the deodorizing portion is provided on the inner circumferential surface of the inserting portion so as to protrude inward, the deodorizing portion has a larger area exposed to the air (odor) inside the container body. Therefore, the deodorizing portion is more likely to come into contact with the odor rising from the inside of the container body over a larger area, thereby achieving more effective deodorization.

[0022] In addition, when the closed body includes a human body sensor for opening the insertion port, and the deodorizing portion is provided on the same side as the human body sensor, since the operator is usually located near the human body sensor in order to operate the human body sensor, the deodorizing portion effectively removes in advance the odor that attempts to flow from the insertion port to the human body sensor, so that the operator does not have to smell the odor.

[0023] Furthermore, when the container body includes a discharge port capable of discharging waste liquid, waste liquid generated from waste products inside the container body can be discharged to the outside of the container body, thereby preventing odor from being generated inside the container body.

[0024] Furthermore, the closing body includes a display capable of displaying the time the insertion port has been closed. This allows visualization of the time the insertion port has been closed, thereby prompting the operator to take prompt action, such as accelerating the insertion of waste products. In this manner, when inserting a predetermined waste product while the insertion port is open, for example, closing the insertion port before the waste product has been inserted, requiring the insertion port to be opened again, and resulting in an increase in the number of opening and closing operations that takes more time than necessary, can be avoided.

[0025] Furthermore, when the closing body includes a human body sensor for opening the insertion port, and when the human body sensor is detected while the insertion port is open, the insertion port remains open for a longer period of time. This extended period allows the operator to perform the insertion operation without rushing and complete the insertion operation before the insertion port closes. Thus, for example, a situation is avoided in which the insertion port is closed before the waste product is inserted, requiring the insertion port to be opened again, and the number of opening and closing operations resulting in a greater time than necessary is increased.

[0026] In addition, in a case where the closed body includes a human body sensor for opening the insertion port, and the human body sensor is capable of switching between an operating mode (in the operating mode, the insertion port is opened when sensing is performed) and a non-operating mode (the non-operating mode maintains the insertion port in a closed state), by setting the non-operating mode, when the operator performs maintenance such as cleaning, disassembly and adjustment of the container, for example, accidental opening and closing caused by the operator, injury to the operator due to the reaction of the human body sensor, damage to the container by falling, etc. can be prevented.

[0027] Advantageous Effects of the Invention

[0028] The waste container according to the present invention can prevent odor from being diffused to the outside from an insertion port that is opened and closed when discarding waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] [ Figure 2 ] is a bottom-up stereoscopic view of the closed body.

[0031] [ Figure 3 ] is a three-dimensional view of a trash can from above.

[0032] [ Figure 4 ] is along Figure 3 A cross-sectional view of the driving portion taken along line AA in FIG.

[0033] [ Figure 5 ] is along Figure 3 A cross-sectional view of the driving portion taken along line BB in FIG. DETAILED DESCRIPTION

[0034] In the following, reference will be made to Figures 1 to 5 The trash can A of the present invention is described and is provided for understanding the present invention.

[0035] First, if Figure 1As shown, a trash can A, serving as an example of a waste container, is primarily composed of a container body 1 having a generally rectangular parallelepiped shape and an open upper portion, and a closed body 2 placed and attached to the upper portion of the container body 1. The container body 1 is formed into a generally rectangular parallelepiped shape with a height of approximately 60 cm, a width of approximately 30 cm, and a depth of approximately 30 cm. Note that the size and shape of the container body 1 are not limited to this embodiment and can be arbitrarily determined. For ease of description, when the trash can A is installed, the direction in which the closed body 2 is positioned relative to the container body 1 is referred to as "upward," and the direction in which the container body 1 is positioned relative to the closed body 2 is referred to as "downward."

[0036] An opening 10 is provided at an upper portion of the container body 1, and the closing body 2 is attached to substantially close the opening 10 of the container body 1. Generated waste products such as kitchen waste are inserted from an insertion port 22, which is provided in the closing body 2 and will be described below, and are stored in the container body 1 through the opening 10.

[0037] The inner lid portion 3 is provided with a bag holding hole 30, to which a garbage bag as an example of a storage bag can be attached, and is attached to the inside of the container body 1. The bag holding hole 30 is formed with a length and width size of approximately 19 cm by approximately 19 cm, and a raised portion 30a that rises to a height of approximately 2 cm is formed over the entire periphery of the peripheral edge of the bag holding hole 30. The size and shape of the inner lid portion 3 are not limited to those of the present embodiment, but can be determined arbitrarily.

[0038] In addition, the inner lid portion 3 is formed to be narrower than the container body 1. Figure 4 As shown, in a state where the inner lid portion 3 is attached to the container body 1, gaps 31 and 31 having a width of approximately 4 cm are formed on both sides of the inner lid portion 3 between the inner lid portion 3 and the inner surface of the container body 1. In addition, the inner lid portion 3 is hooked in the container body 1 by hooks 32 and 32 provided to extend approximately 1 cm from the inner surface of the container body 1 toward the center of the container body 1. The means for hooking the inner lid portion 3 in the container body 1 is not limited to the mode of this embodiment, but can be determined arbitrarily.

[0039] The opening of the garbage bag below the inner lid 3 is pulled out from the bag holding hole 30 and inserted into the gaps 31 and 31 on both sides of the inner lid 3 to cover the rising portion 30a.

[0040] In addition, if Figure 1As shown, a bottom plate 4 having a drain hole 40 capable of draining waste liquid generated inside the container body 1 is attached to the bottom of the container body 1. A drain hole cap 41 is attached to the drain hole 40 to seal the drain hole 40, and the waste liquid generated inside the container body 1 does not leak from the container body 1. In addition, by removing the drain hole cap 41 from the drain hole 40, the waste liquid generated inside the container body 1 can be drained to the outside of the container body 1.

[0041] like Figure 2 As shown, the closed body 2 is composed of a base 20 and an inserting portion 21 that can be assembled to the container body 1. Figure 3 As shown, the front surface 20A of the base 20 is provided with an insertion port 22 through which waste products are to be inserted, and an insertion port frame 22a is provided along the edge of the insertion port 22. An opening and closing portion 23 for substantially closing the insertion port 22 is slidably provided on a side corresponding to the rear surface 20B of the base 20 so as to substantially contact the base 20. In addition, an operation panel 24 for operating the opening and closing action of the opening and closing portion 23 is provided on an upper surface (reference numeral omitted) of the insertion port frame 22a.

[0042] Insertion port frame 22a is formed into a generally quadrilateral shape having a width of approximately 24 cm and a depth of approximately 24 cm, and the upper surface of insertion port frame 22a is located approximately 1 cm higher than front surface 20A of closed body 2. An operation panel 24 is provided on the upper surface of frame member 221 of the four frame members 221, 222, 223, and 224 that constitute insertion port frame 22a. An operator approaches frame member 221, operates operation panel 24, opens insertion port 22, and inserts waste products through insertion port 22.

[0043] The operation panel 24 includes a human body sensor 240, a closing button 241 and an opening button 242. The human body sensor 240 senses human movement, such as holding a hand on the device. The closing button 241 causes a pair of opening and closing members 233 and 233 to close the insertion port 22, and the opening button 242 causes the pair of opening and closing members 233 and 233 to open the insertion port 22.

[0044] Furthermore, when the human body sensor 240 senses the operator's hand within the sensing area of ​​the human body sensor 240, the pair of opening and closing members 233 and 233 move toward the advance and retreat opening 22c of the insertion portion 21 via the drive unit 25 to open the insertion port 22. Alternatively, the insertion port 22 can be opened and closed by operating the closing button 241 and the opening button 242. In this embodiment, the sensing area and sensitivity of the human body sensor 240 can be arbitrarily changed.

[0045] In addition, if Figure 3As shown, the base 20 of the closed body 2 is provided with five lighting devices 26 for displaying the time from the open state to the closed state of the insertion port 22. In this embodiment, the lighting devices 26 are not provided so as to be exposed on the front surface 20A of the base 20, but are provided inside the base 20. Therefore, the light emitted from the lighting devices 26 is visually recognized through the slits 27 provided in the front surface 20A of the base 20.

[0046] When the insertion port 22 is fully open, the five lighting devices 26 illuminate. The insertion port 22 then remains open for approximately five seconds, with the lighting devices 26 extinguishing sequentially from one end per second, depending on the remaining open time. This visual display of the remaining open time for the insertion port 22 urges the operator to quickly insert waste into the insertion port 22. Furthermore, the likelihood of the insertion port closing before the waste is fully inserted, necessitating reopening, is reduced. Consequently, the reduced frequency of opening and closing the insertion port prevents odors from leaking to the outside.

[0047] Furthermore, after about five seconds have passed while the insertion port 22 remains open, all the lighting devices 26 are turned off. The pair of opening and closing members 233 and 233 then advance from the advance and retreat opening 22c provided near the frame members 222 and 224 toward the approximate center of the insertion port 22, thereby closing the insertion port 22.

[0048] Furthermore, when the operator places their hand within the sensing area of ​​human body sensor 240 while insertion port 22 is open, human body sensor 240 senses the operator's hand, extending the opening of insertion port 22 by several seconds. This makes it easy to adjust the time during which the operator can insert waste into insertion port 22, and prevents insertion port 22 from being opened again. In other words, insertion port 22 is prevented from being opened multiple times during a single insertion event, thereby preventing odors from within container body 1 from leaking to the outside.

[0049] Furthermore, the human body sensor 240 has a structure capable of switching between an operating mode, in which the insertion port 22 is opened when human motion is sensed, and a non-operating mode, in which the human body sensor 240 does not sense human motion and the insertion port 22 remains closed. When the non-operating mode is set, for example, when an operator performs maintenance such as cleaning, disassembling, and adjusting the container, accidental opening and closing by the operator, injury to the operator due to the reaction of the human body sensor, and damage to the container from falling can be prevented.

[0050] like Figure 1As shown, the insert portion 21 is provided on the rear surface 20B of the closed body 2 and is formed into a frame shape with a length and width of approximately 27.5 cm by approximately 27.5 cm. The insert portion 21 is inserted into the container body 1 through the opening 10 of the container body 1 and is placed and attached. Since the closed body 2 substantially closes the opening 10 in this manner, odors inside the container body 1 are prevented from leaking to the outside.

[0051] like Figure 4 As shown, the opening and closing portion 23 is composed of a pair of opening and closing members 233 and 233 that advance and retract in opposite directions from approximately the center of the insertion port 22. Each opening and closing member 233 and 233 is composed of a slide plate 230, which is a longitudinally long, parallel plate-shaped member, and a connecting portion 231 that connects adjacent slide plates. In this embodiment, each of the pair of opening and closing members 233 and 233 is composed of five slide plates 230, but this is not limiting. The number of opening and closing members in the pair can be arbitrarily determined.

[0052] In addition, the position of the edges 232 and 232 that abut against each other when the pair of opening and closing members 233 and 233 are closed is not limited to being approximately near the center of the insertion port 22. For example, a structure can be adopted in which the opening and closing members 233 and 233 are closed at any position near the frame members 222 and 224 of the insertion port frame 22a. In addition, a single opening and closing member can be used instead of the pair of opening and closing members. In this case, although it takes more time for the insertion port 22 to be fully opened than with a pair of opening and closing members, the drive unit for opening and closing the opening and closing members can be simplified, and the weight of the closed body 2 can be reduced.

[0053] like Figure 4 As shown, each connecting portion 231 is composed of a shaft member 231a and a bearing portion 231b, and the shaft member 231a is arranged so that it can slide and rotate within the bearing portion 231b while being clamped by the shaft member 231a. As a result, the adjacent slides 230 of the opening and closing members 233 and 233 are arranged continuously, and at the same time, the adjacent slides 230 can be bent by the connecting portion 231, while changing their angles.

[0054] The edge portions 232 and 232 of the pair of opening and closing members 233 and 233 facing each other are formed so as to be in close contact when the insertion port 22 is closed. Figure 4 As shown, a structure is formed in which projections and recesses that can be assembled in close contact with each other are formed in the edge parts 232 and 232. The shape or assembly method of the edge parts 232 and 232 is not limited thereto, and a structure in which the edge parts are in close contact with each other via a packaging material or the like can be considered.

[0055] The insertion section 21 is composed of insertion members 21a and 21b and connecting members 21c and 1d. The insertion members 21a and 21b are arranged approximately parallel to the slide 230 of the opening and closing section 23 and are suspended downwardly at a length of approximately 10 cm. Furthermore, connecting members 21c and 21d are arranged approximately perpendicular to the slide 230, connecting the insertion members 21a and 21b at their upper portions, and are suspended approximately 6 cm in length. The insertion members 21a and 21b are hollow and have accommodating spaces 210 and 210 capable of accommodating the pair of opening and closing members 233 and 233.

[0056] Furthermore, when the closed body 2 is attached to the container body 1, the insertion members 21a and 21b are inserted into the gaps 31 and 31 between the inner lid portion 3 and the container body 1. At this time, although the upper portions of the outer surface of the insertion members 21a and 21b are in roughly close contact with the inner surface around the edge of the opening 10, the insertion members 21a and 21b gradually separate downward due to their downwardly tapered shape. Thus, the insertion members 21a and 21b can be inserted into the gaps 31 and 31 without difficulty. The portion where the outer surface of the insertion members 21a and 21b is in roughly close contact with the inner surface of the container body 1 allows the closed body 2 to roughly close the opening 10 of the container body 1.

[0057] Furthermore, by sandwiching the opening of the garbage bag between the inner lid 3 and the insert members 21a and 21b, a structure is provided in which the garbage bag is secured by the inner lid 3 and the insert members 21a and 21b and is not easily removed. Furthermore, by securely fitting the container body 1 and the closed body 2, the closed body 2 is attached to the container body 1 in close contact.

[0058] When insertion members 21a and 21b are inserted into gaps 31 and 31 between inner lid portion 3 and container body 1, raised portion 30a of bag-retaining hole 30 of inner lid portion 3 fits into insertion portion 21 along inner circumferential surface 211 of insertion portion 21. Thus, not only is closed body 2 inserted into container body 1, but also waste passage 212 formed by inner circumferential surface 211 of insertion portion 21 (and through which waste passes) communicates with bag-retaining hole 30 of inner lid portion 3. Specifically, when waste inserted from insertion port 22 passes through waste passage 212 of insertion portion 21 and then through bag-retaining hole 30, the waste is securely stored in the waste bag from bag-retaining hole 30 because the waste bag is attached to bag-retaining hole 30.

[0059] In addition, if Figure 4As shown, when the insertion port 22 is opened, the pair of opening and closing members 233 and 233 retreat in opposite directions from the approximate center of the insertion port 22 along the guide portion 22b and enter the advance and retreat opening 22c, and the slides 230 of the opening and closing members 233 and 233 are bent through the connecting portion 231 near the frame members 222 and 224 of the insertion port frame 22a to be accommodated in the accommodating spaces 210 and 210.

[0060] Conversely, when closing insertion port 22, the opening and closing members 233 and 233 housed in storage spaces 210 and 210 are drawn out of storage spaces 210 and 210, extending through coupling portion 231 and advancing from advance and retreat opening 22c along guide portion 22b. The edge portions 232 and 232 of the opening and closing members 233 and 233 fit approximately at the center of insertion port 22, thereby closing insertion port 22. In this manner, the pair of opening and closing members 233 and 233 mesh with gears 253 and 253 and move while deforming in a curved shape between insertion port 22 and storage spaces 210 and 210, allowing insertion port 22 to be opened and closed.

[0061] Specifically, the guide portion 22b provided on the rear surface 20B of the base body 20 is formed into a generally straight line and is arranged approximately parallel to the rear surface 20B. Thus, the pair of opening and closing members 233 and 233 advance and retract approximately horizontally along the guide portion 22b provided on the rear surface 20B of the base body 20 (the movement path of the opening and closing members), then advance and retract while deforming into a curved shape near the frame members 222 and 224, and then advance and retract approximately vertically within the storage spaces 210 and 210. At this time, the pair of opening and closing members 233 and 233 open and close the insertion port 22 along the guide portion 22b, and advance and retract approximately parallel to and approximately horizontally with the rear surface 20B, thereby preventing the odor within the container body 1 from being significantly disturbed.

[0062] Furthermore, as the insertion portion 21 is inserted into the container body 1, the pair of opening and closing members 233 and 233 advance and retract within the container body 1. Furthermore, the pair of opening and closing members 233 and 233 are accommodated within the accommodation spaces 210 and 210 through the advancement and retreat opening 22c. However, since the accommodation spaces 210 and 210 are formed of an airtight material and separated from the exterior of the insertion portion 21 (i.e., the interior of the container body 1), the advancement and retreat of the pair of opening and closing members 233 and 233 within the accommodation spaces 210 and 210 does not disturb the air within the container body 1. This prevents odors from within the container body 1 from leaking to the outside.

[0063] The storage spaces 210 and 210 are connected to the outside at the entry and exit openings 22c and are not airtight. However, when the pair of opening and closing members 233 and 233 advance and retreat within the storage spaces 210 and 210, the turbulence of the air is contained within a predetermined range (i.e., no significant air turbulence is generated outside the storage spaces 210 and 210). Therefore, the possibility of the odor inside the container body 1 being disturbed and leaking from the container body 1 to the outside can be similarly prevented.

[0064] That is, because the opening and closing members 233 and 233 perform this series of forward and backward movements, when the pair of opening and closing members 233 and 233 advance and retreat approximately horizontally near the insertion port 22, a slight flow is generated in the surrounding air, but no significant air disturbance is generated within the container body 1. On the other hand, when the pair of opening and closing members 233 and 233 advance and retreat within the accommodating spaces 210 and 210, they are unlikely to disturb the surrounding air, and certainly not the air within the container body 1. Therefore, the closed body 2 has a structure that prevents odors within the container body 1 from being diffused to the outside by the forward and backward movement of the opening and closing members 233 and 233.

[0065] like Figure 2 As shown, the connecting member 21c is provided with a battery compartment BX and a switch SW, and can be operated to supply or stop power to the operation panel 24 and the drive unit 25, as will be described below. When receiving power, the operation panel 24 moves the pair of opening and closing members 233 and 233 via the drive unit 25 to open and close the insertion port 22.

[0066] like Figure 5 As shown, the driving unit 25 is provided in the insertion portion 21 and is composed of a motor 250, a power transmission shaft 251, driving gears 252 and 252, gears 253 and 253, and a driven shaft (not shown), and is provided in the connecting member 21c. The motor 250 rotates the power transmission shaft 251, and the driving gears 252 and 252 provided at both ends of the power transmission shaft 251 rotate the gears 253 and 253, thereby advancing and retracting the two opening and closing members 233 and 233.

[0067] That is, circular racks 254 and 254 having a common rotation center with the gears 253 and 253 are provided, and both mesh with the drive gears 252 and 252 on the inner side (the side close to each other). The outer peripheral portions of the gears 253 and 253 have engaging recesses 255, which mesh with the shaft member 231a of the coupling portion 231 on the rear surface of the opening and closing members 233 and 233. The gears 253 and 253 rotate synchronously in directions opposite to each other by the forward and reverse rotation of the motor, and cause the opening and closing members 233 and 233 to advance and retract in opposite directions. Note that the gears 253 and 253 for moving the opening and closing members 233 and 233 are provided in pairs, and are attached to both ends of the driven shaft and provided in the connecting member 21d.

[0068] That is, the power of the motor 250 is transmitted to the power transmission shaft 251 through the human body sensor 240 or the open button 242 of the operation panel 24, and the gears 253 and 253 rotate via the driving gears 252 and 252. By the engagement between the engagement recesses 255 of the gears 253 and 253 and the shaft members 231a of the opening and closing members 233 and 233, the pair of opening and closing members 233 and 233 advances and retracts.

[0069] The deodorizing unit 5 is provided on a component surface 211a, which forms part of the inner circumferential surface 211 of the insertion portion 21. The component surface 211a is located on the same side as the operation panel 24 (i.e., within the inner circumferential surface 211, the inner circumferential surface of the connecting member 21c and the surface through which waste passes when passing through the waste passage 212 from the frame member 221 on which the operation panel 24 is provided), or is located below (directly below) the operation panel 24. The deodorizing unit 5 is composed of a chamber 50 containing a deodorant (not shown) and a accommodating recess 51 provided in the inner circumferential surface 211 and capable of accommodating the chamber 50. When the trash can A is used, the chamber 50 is inserted into the accommodating recess 51 for use.

[0070] Among the surfaces of the bin 50 protruding from the constituent surface 211a, the front surface 50a and the lower surface 50b of the bin 50 are provided with a plurality of ventilation holes 52. Odors generated by waste stored in the container body 1 and rising within the container body 1 are removed by the deodorizing component leaking from the ventilation holes 52. At this time, since the front surface 50a and the lower surface 50b of the bin 50 provided with the ventilation holes 52 of the bin 50 are provided so as to protrude from the constituent surface 211a, the area over which the odor and the deodorant come into contact with each other through the ventilation holes 52 increases, which can enhance the deodorizing effect.

[0071] The deodorizing portion 5 is not limited to protruding from the inner peripheral surface 211 , and may be embedded in the insertion portion 21 so that the front surface of the deodorizing portion 5 is substantially flush with the constituting surface 211 a .

[0072] With the trash can A having such a structure, waste is inserted from the insertion port 22 provided in the closed body 2 and opened by a pair of opening and closing members 233 and 233, so that the possibility of odor generated from the waste in the container body 1 easily leaking to the outside can be prevented.

[0073] Next, there will be described a method of using the trash can A. The insertion port 22 of the trash can A is initially closed.

[0074] The operator stands in front of the trash can A (i.e., near the frame member 221 of the insertion port 22) and brings his hand close to the human body sensor 240 of the operation panel 24 while holding the trash. When the operator's hand enters the sensing area of ​​the human body sensor 240, the human body sensor 240 senses the operator's hand, and the pair of opening and closing members 233 and 233 are opened via the driving unit 25.

[0075] Furthermore, when the insertion port 22 is opened, the pair of opening and closing members 233 and 233 move approximately horizontally near the insertion port 22, are inserted from the advance and retreat opening 22c, and then bend while rotating along the gears 253 and 253, and are suspended in the insertion members 21a and 21b.

[0076] At this time, as described above, since the opening and closing members 233 and 233 move forward and backward stably under the action of the guide portion 22b, no significant air disturbance is generated within the container body 1. When the opening and closing members 233 and 233 move forward and backward within the accommodating spaces 210 and 210, the surrounding air is not significantly disturbed. Therefore, the odor within the container body 1 is not disturbed by the movement of the opening and closing members 233 and 233, thereby preventing the odor caused by opening and closing from leaking to the outside.

[0077] Furthermore, since the opening and closing portion 23 steadily advances and retracts in the left-right direction to open and close, no significant air disturbance occurs within the container body 1 during opening and closing, thereby preventing odors from leaking to the outside due to opening and closing. Furthermore, since the slide plate 230 has a flat shape, this structure prevents air disturbance even when the slide plate 230 advances and retracts.

[0078] Since the deodorizing portion 5 is provided on the constituting surface 211a of the insertion portion 21, when the closed body 2 is attached to the container body 1, the deodorizing portion 5 is provided on the constituting surface 211a of the insertion portion 21. Therefore, regardless of the open / closed state of the insertion port 22, the odor generated in the container body 1 and rising to the vicinity of the opening 10 can be effectively removed.

[0079] If the deodorizing portion is provided on the surface opposite to the structured surface 211a, the inserted waste may hit the deodorizing portion located on the opposite surface due to the momentum in the direction of the opposite surface. However, since the deodorizing portion 5 is provided on the structured surface 211a of the insertion portion 21, the inserted waste is less likely to hit the deodorizing portion 5, and the deodorizing portion 5 is prevented from being removed from the accommodating recess 51.

[0080] In addition, the deodorizing unit 5 is attached to protrude from the forming surface 211a, and the front surface 50a and the lower surface 50b of the chamber 50 of the deodorizing unit 5 have ventilation holes, all of which are exposed. Therefore, the odor and the deodorant can be effectively brought into contact with each other, thereby improving the deodorizing efficiency.

[0081] Since the deodorizing portion 5 is provided on the constituting surface 211a of the inserting portion 21, the deodorizing portion 5 is located at a position where it is difficult for the operator to visually recognize the deodorizing portion 5. Therefore, the design of the trash can A is not impaired.

[0082] Furthermore, since the insertion port 22 communicates with the waste passage 212 of the insertion portion 21 and the bag holding hole 30 of the inner lid portion 3 , waste inserted through the insertion port 22 can be properly stored in the garbage bag.

[0083] As described above, the waste container according to the present invention is a waste container capable of preventing odor from being diffused to the outside from the opened and closed insertion port when waste is discarded.
