[0002]

2. Description of the Related Art In general, general-purpose garbage, excluding large garbage, includes paper, kitchen waste, fiber,
Combustible materials such as wood, bamboo and plastic pieces, and other non-flammable materials such as rubber, metal, glass, and ceramic,
Classified as unsuitable for combustion.

[0003] The non-combustible and non-combustible materials include razor blades and dry batteries.

[0004] The garbage container for storing such general garbage is a garbage bag such as a plastic bag, a paper bag, a poly bucket (a plastic bucket such as a polypropylene resin), or the like.

[0005] By the way, the amount of landfill waste is reduced due to the increase of the general waste, and the waste is treated by recycling the waste.

[0006] In this treatment method for collecting waste resources, it is an effective means to classify and discharge, that is, separate, general waste according to resources, and it is encouraged.

The applicant of the present invention has made many proposals (for example, Japanese Utility Model Registration No. 2608893, Utility Model Registration No.
Japanese Patent Application Laid-Open No. 502139, Japanese Unexamined Patent Application Publication No. 10-81401, etc.). Of course, a large number of technologies have been introduced and proposed from a long time by other than the present applicant.

For example, a general technical example of the hinged lid 109 of the separating plastic trash box 100 shown in FIG. 8 described in Japanese Utility Model Registration No. 2500412 will be described.

That is, a rectangular garbage box main body 101 having a bottomed upper opening type is removably covered with an eyeglass-shaped lid frame 102 at its upper opening by a clamp 103 provided on a side surface thereof. Have been.

The lid frame 102 is formed with an outer flap 104 for covering the upper opening of the trash box main body 101, and has two garbage inlets 10 opening vertically.
5, 105 are formed.

The shape of the refuse inlet 105 is such that the front surface of the trash box 100 (the long side in the rectangular body of the trash box main body 101 is the front or rear surface, for example, the rear surface is the wall surface side, and The side on which the user stands alone is referred to as the front side. The same applies to the following side, and the arc end faces the horseshoe shape, and the periphery thereof is surrounded by the rising 106 and the lid mounting shore 107 provided at the rear.

The rising portion 106 is formed with a stepped portion 108 having a shelf on the outer peripheral side thereof, and a flap 110 provided on an inverted shallow dish-shaped horseshoe-shaped hinged lid 109 is brought into contact with the stepped portion 108. ing.

[0013] The hinged lid 109 is attached to the lid mounting shore 1.

View side view,
FIG. 7C is a cross-sectional view taken along the arrow C in FIG. 5, FIG. 7 is a detailed view of another main part in FIG. 2, and FIG.
(B) is a side view as viewed in the direction of arrow B in FIG. 7 (A).

A plastic trash can 1 according to an embodiment of the present invention.
Is an injection or blow-molded product of PP resin, and the trash box main body 2 is a deep-bottomed upper-opening rectangular shape slightly narrowed downward in a front view and a side view. 5
50mm, opening side long side about 450mm, short side about 250m
m. Therefore, the long side is constituted by a rectangular parallelepiped approximately twice as long as the short side.

This plastic trash can 1 can be installed outdoors, of course, and is particularly installed in kitchens of general households, kitchens of business cafeterias, rooms of office buildings, and the like, and is used as a trash can for sorting.

Therefore, in a preferred example of the trash box 1, two trash inlets 3 are opened on its horizontal upper surface,
These waste inlets 3 are opened and closed by a hinged lid (which is a lid pivotally supported by a hinge portion and opened by rotating the lid from a closed state to a raised state at least).

Now, the features of the trash can 1 of this embodiment will be outlined.

In FIG. 1, a trash can 1 according to the present embodiment has a trash can body 2 with or without casters, and one main lid 5 covering the entire opening of the trash can body 2.
Hinged covers 4,4 and / or grandchild covers 6,6 for covering two or more refuse inlets 3,3,3a, 3b provided in the main lid 5, respectively. In particular, the hinged lids 4, 4 which are always used are hingedly connected to the lid frames 7, 7, which can be easily attached to and detached from the main lid 5 at the installation location and can be changed in mounting. It is designed to open and close.

The opening direction of the hinged lid 4 is as follows.
Even if the user stands on the side of the trash box 1, the user always faces the user from the near side to the rear side.

That is, as shown in FIG. 1 (A), the trash can 1 is usually provided as shown in FIG. 1 (A) due to restrictions such as space, viewing, and secrecy at the installation location, and one trash can 1 being sandwiched between a pillar and a wall. It can be used horizontally for installation, or as a vertical installation for special installation in which the user stands on the side and throws in garbage as shown in FIG. 1 (B).

Therefore, in order to place the camera vertically, remove the cover frame 7 from the main cover 5 and replace the cover frame 7 (90).
(To change the orientation), the hinged lid 4 can be opened from the front to the rear as viewed from the user.

In the trash box 1, a single trash bag (also called a polybag, not shown) is used for one trash input port 3 for separation, and a partition plate reaching the bottom. Is not used, the garbage bag can be freely filled with garbage in the garbage box main body 2 without being restricted by the partition plate.

For this garbage bag, a garbage bag holder (not shown)
The garbage bag support plate 8 is required.
Is extended from substantially the center on the front side to substantially the center on the rear side at the opening of the trash box main body 2. Then, the main lid 5 is removed to attach or remove the garbage bag.

Further, in the trash box 1, when the normally open trash inlet 3 which does not require the hinged lid 4, the hinged lid 4 may be removed from the master lid 5 together with the lid frame 7. Even in this case, since the garbage bag is fixed by the main lid 5, it does not hinder the refuse input. Therefore, the trash can 1 can be diversified in usage.

In particular, to open the hinged lid 4, the user presses a pressing piece 20 (see FIG. 5) of the lid frame 7, which is provided in front of the user from the user, with his / her finger. The engagement with the lid 4 is released, and the spring is automatically sprung up and rises relatively vigorously by the spring force of a coil spring or a leaf spring (both not shown) provided on the hinge side of the hinged lid 4. Of course, when closing, the upper surface of the hinged lid 4 is pressed against the spring force, and the lid frame 7 and the hinged lid 4 are engaged again.

Accordingly, when the hinged lid 4 is opened, if the hinged lid 4 rises from the down position to the left or right of the user, the hinged lid 4 is only pressed by the finger of the pressing piece 10 of the lid frame 7. The lid 4 may touch the body of the female or female user.

However, since the hinged lid 4 of this embodiment always opens rearward from the user, there is no need to worry.

Of course, the hinged lid 109 of the conventional example shown in FIG.
00 cannot be used.

Next, the main lid 5, lid frame 7, hinged lid 4, and trash bag support plate 8 of the trash box 1 will be described in detail. These are all made of plastics, especially PP injection molded products.

First, a lid (may be referred to as a lid frame)
5 mainly correspond to FIGS. 2, 3 and 4 (center line a in FIG. 3).
The left side is a sectional side view with the hinged lid 4 and the lid frame 7 left, the right side is a side sectional view without them, and FIG. 4 shows a side view of the garbage bag support plate 8 in particular). It is formed in the shape of a dish and covers the entire surface of the upper opening of the trash box main body 2, but is fixed to be openable and closable by clamps 9, 9 provided on the side surfaces thereof. Therefore, since the main lid 5 is configured symmetrically, the main lid 5 can be covered by changing the direction by 180 °.

Further, by covering the main lid 5, a garbage bag holder (not shown, a substantially U-shaped piece whose end is pivotally supported) is pressed from above to be fixed. The area around the open mouth of the supported garbage bag is also pressed and fixed.

The main lid 5 is provided with two symmetrical (or irregularly shaped) refuse inlets 3 and 3 symmetrically (of course, the razor input port 3a and the dry battery input port 3b shown in FIG. 1). May be further provided), and these dust input ports 3 are formed in a square shape. Incidentally, it is a square of about 180 mm square on one side.

A pressing rib 10 for the garbage bag support plate for loosely engaging with the garbage bag support plate 8 and sandwiching the periphery of the open mouth of the garbage bag is provided on the back surface of the main lid 5. It protrudes at the center of the side and at the middle between the front side and the rear side.

As shown in FIG. 4, the pressing rib 10 connects the pair of right and left meshing pieces 11, 11 to each other, and connects the central vertical plate 12 of the garbage bag support plate 8 to the pair. Since the connecting piece 13 is roughly constituted by two (only one is shown in FIG. 3) engaging pieces 13 from above, the main lid 5 is fixed to the trash box main body 2 by covering the main lid 5 with the trash box main body 2. The garbage bag supporting plate 8 loosely meshes with the garbage bag, and the garbage bag supported by the garbage bag 8 is pressed around the mouth of the garbage bag and fixed.

The refuse inlet 3 is vertically opened. At the opening, a flap-shaped lid frame guide enclosure 14 is folded downward from the horizontal upper surface of the main lid 5. At the lower end of the frame guide cover 14, support frame steps 15 are provided inwardly facing each other (see FIG. 4) to support the fitted cover frame 7 from above.

Of course, the projecting amount of the supporting step 15 is
The opening area of the refuse inlet 3 is not reduced by the thickness of the lid frame 7.

Next, the lid frame 7 will be described. mainly,
2 and 5 (the left side is a bottom view and the right side is a plan view from the vertical center line in FIG. 5) and FIG. 6, the two lid frames 7 have the same shape (or different shapes). It is detachably fitted to the guide enclosure 14 of the main lid 5 from above.

Since the lid frame 7 is provided with the square hinged lid 4, the lid frame 7 is also a square surrounding frame in a plan view. A pair of left and right hinge pins 17 and 18 project integrally and face each other.

The hinged lid 4 is pivotally supported by the hinge pins 17 and 18, and a coil spring is wound around the long hinge pin 17 (not shown).

Two (total of eight or four) tongue pieces 19 are integrally hung on each side or right and left sides of the lid frame 7, and a horizontal ridge-shaped engaging member is attached to the outer surface of the tongue piece 19. Stop Potch 1
6 are formed outwardly and engage with the lower end of the guide enclosure 14.

Therefore, the tongue piece 19 is slightly bent inward by the deformation of the resin, and the lid frame 7 is fitted to the dust inlet 3 of the main lid 5.

In particular, an inverted L-shaped (see FIG. 6 (C)) pressing piece 20 as viewed from the side is extended integrally with the lid frame 7 at the upper end on the front side as viewed from the user. Presses this to remove the lid opening / closing potch 21 formed on the base side of the pressing piece 20 from the lid opening / closing potch 22 formed on the hinged lid 4.

That is, these lid opening / closing potches 21,
22 are engaged with each other, and when the lid 4 with the hinge is opened, when the pressing piece 20 is pressed, the lid 21 comes off from the resin 22 against the resin elasticity, and when the lid 4 with the hinge is closed, the lid with the hinge is closed. When the upper surface of 4 is pressed with a palm or the like, 21 moves over and locks against 22 against the resin elasticity of the base side of pressing piece 20.

In order to smoothly engage and disengage the lid opening / closing potches 21 and 22 with the pressing piece 20, the pressing piece 20 is slightly higher than the horizontal upper surface of the main lid 5 and is extended forward. It is provided so as to be close to the user.

The pressing amount of the pressing piece 20 is as shown in FIG.
As shown in (2), the pressing piece 20 is restricted to be in contact with the horizontal upper surface to prevent unnecessary pressing and prevent the pressing piece 20 from being broken.

Further, by gripping the pusher 20, the lid frame 7 can be removed from the main lid 5.

The tongue piece 19 and the pressing piece 20 are provided with cutouts on both sides to facilitate elastic deformation of the resin.

The lid frame 7 is necessary to secure the hinge connection of the hinged lid 4 and to easily change the opening / closing direction. If there is, that is, if the labor of attaching and detaching the hinge connection is sacrificed, the guide enclosure 1 of the refuse inlet 3 of the main lid 5 can be provided.
4, a pair of hinge pins may be directly provided at right angles to each other so that the hinged lid 4 can be attached and detached at the installation location of the trash box 1.

Next, the hinged lid 4 will be described. As shown mainly in FIG. 2, FIG. 3, FIG. 6 (A) and FIG. 6 (C), the hinged lid 4, which is a child lid, is formed in a square inverted shallow dish having a side of about 164 mm square. The lid opening / closing potch 22 is integrally formed on the outer surface on the front side of the plate folding piece.

A hinge pin hole 23 for loosely fitting the hinge pins 17 and 18 is formed behind the hinged lid 4.

Next, a garbage bag support plate (also called a partition plate) 8
Is described. 2, 3, 4, and 7, the garbage bag support plate 8 is provided at an opening of the trash box main body 2.
The pressing rib 1 for a garbage bag support plate, which is provided to extend from the center on the front side to the center on the rear side, but protrudes from the back surface of the main lid 5.
0, in particular, a pair of mating pieces 11 so as to be engaged with each other so as to be engaged with each other, a vertical central plate 12 which is long in the vertical direction and protrudes downward, and which is parallel to both sides thereof. Lower upper only vertical side plates 24, 24 and these three plates (1
2, 24, 24) standing upright, and a long strip-shaped horizontal plate body 25, and a trash can body 2 at both ends of the horizontal plate body 25.
And an insertion piece 26 for fixing the garbage bag support plate 8 to the opening shoulder 28 of the opening.

Therefore, the horizontal plate main body 24 of the garbage bag support plate 8 is supported at both ends by the opening of the trash can main body 2,
Support around the open mouth of the garbage bag.

In order to prevent the horizontal plate main body 24 from bending downward, one vertical center plate 1
Two and two vertical side plates 24, 24 protrude.

The garbage bag support plate 8 is set on the garbage bin main body 2 at a production factory or the like, and in order to prevent the delusion, the ends of the vertical central plate 12 projecting downward and both ends of the horizontal plate main body 24 are set. Sides of the garbage bin main body 2 are sandwiched by guide plates 27, 27 projecting downward on the sides of the trash box main body 2, and the insertion piece 26 is a forked downward plate body. It is configured to prevent left and right swaying when viewed from the front (see FIG. 4).

Therefore, the trash bag support plate 8 is not a conventional partition plate that reaches the bottom of the trash box main body, but is a frame member (for example, Japanese Patent Laid-Open No. 7-3) that surrounds the inside of the opening of the trash box main body.
No. 23901), it is a mere passing piece, and does not bend downward even if it supports a part of the open mouth of the garbage bag, and one garbage bag is used for the trash box main body 2. At times, it can be easily removed and, furthermore, the garbage bag support plate 8 can be stored at the bottom.

The trash box 1 of the present invention not only separates and stores garbage from homes, but also separates and stores garbage such as office paper from offices and general garbage from public places such as hospitals. Can be.

The present invention is not limited to a trash can having two trash cans, but may be a trash can having three or more (plural) trash cans as far as the user can reach. Further, a plurality of these trash boxes may be placed side by side and used side by side.

Of course, the recycle bin 1 can be applied to a hinged lid without a spring, and although not optimal, it can also be applied to a deformed rectangular tube other than a cylindrical one, and a lid without a hinge may be used together. .

[0068]

According to the present invention, a lid (parent lid frame) is provided.
The hinged lid is provided at the installation site, and the opening / closing direction of the hinged lid can be changed by the user at the installation site, so that it is possible to adapt to the restrictions of the installation location. When the direction of covering the main body is changed by 180 °, the opening / closing direction of the hinged lid is further diversified, and can be more finely adapted to the restriction on the installation place of the trash can.

In particular, since the hinged lid always opens from the front to the rear as viewed from the user, it is convenient for dust input work and lid opening / closing operation.

Of course, if the trash box main body is provided with a caster, the trash bag can be loaded and unloaded in a wide place even if the trash box is kept secret.

When a garbage bag is used in the trash box, the main lid can be opened and taken out, which is also advantageous in this respect.
