DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-watertight container made of a plastic flat double wall blow, that is, a flat blow panel container.

[0002]

2. Description of the Related Art As is well known, living environment facilities are in short supply due to rapid economic growth in the 1930s.
After the enactment of various waste disposal laws, especially recently, the Waste Management Law was revised and the Recycling Law was enacted, requiring citizens to separate and discharge waste (referred to as garbage).

[0003] For this reason, garbage discharged from each home or business office is collected and stored at one station, which is called an open station system or a bunker station system. Separation trash cans have been installed there. In addition, a garbage collection box, that is, a garbage bin for sorting, has been installed at a store such as a supermarket, and a recycling station for receiving recycled garbage brought by visitors has also been installed.

[0004] The present applicant has proposed the following regarding such a trash can for separation (see Japanese Patent Application Laid-Open No. 10-81401).

[0005] A trash can body made of a rectangular bottomed container is made of steel, in which a plurality of resin pail (also called bucket-shaped middle container) is stored, and a plastic bag is placed in each pail. In a suspended medium-sized garbage bin for the public, a garbage bin lid with a specially shaped inlet for sorted garbage is provided on the upper surface of the main unit, and the garbage bin lid is inclined forward downward and opened upward. , A front door is provided on the front of the main body so that it opens forward, so that it can be fully opened from the top of the pail to the front,
It has been proposed that the so-called full-open type is used, and that it is small-sized and allows a plurality of pails to be easily put in and out.

[0006] Recently, such steel panels have been made of plastic flat panels (hereinafter referred to as plastics) by a press blowing method (blow compression method), which is a kind of high-tech blow method, for the following reasons. Double-wall blows, ie, blow-panels) (from Shoji Sugiura's Dictionary of Plastics Molding Technology, p. 380).

[0007] That is, steel panels are angular, noisy during sheet metal processing, there is an environmental problem with welding, and the depreciation cost of the press die is too large for various small-quantity production (small lot production). For reasons of disadvantages, the blow panel is designed with a snap-fit (fitting, i.e., integrally forming an engagement projection on one side and a recess on the other side). It is convenient for assembling with a structure that does not become watertight because of the fitting structure, and the die for the blow may be a light alloy for low pressure.

Accordingly, the present inventors have also paid attention to the fact that the above-mentioned fully-opened separation trash can is constituted by a blow panel so as to exhibit the above advantages.

As a result, in addition to these advantages, the full-open type separation trash bin composed of the blow panel is a full-open type and has a rectangular bottomed container. The back plate can be hinged to three parts to make one part, minimizing the number of parts and facilitating the assembly work, and even if the water tightness is impaired by snap-fit, It can be used for confidential document cabinets that may be non-watertight by changing the top plate, that is, the lid with the input port, and it is also suitable for small lot production. We have found new advantages, such as further savings on blow mold depreciation.

On the other hand, a cabinet or storage box made of a blow panel is constructed by connecting both side plates and a back plate of three blow panel plates by a hinge formed by compression molding. A cabinet or the like is known in which engagement projections are provided on upper and lower end surfaces of a plate and snap-fitted into recesses provided on a top plate and a bottom plate, respectively (for example, Japanese Utility Model Laid-Open No. 62-200541, Japanese Unexamined Patent Publication No.
No.-313262).

[0011]

However, such a cabinet has the following problems. Since both side plates and the back plate are bent at or near the hinge portion formed of a compression-molded solid portion, the blow
Compared to steel panels, the panel has the advantage of avoiding cornering and being rounded.

Since the top plate is fixed by snap-fitting to the upper end surfaces of both side plates and the back plate, it is not suitable for a full-open type cabinet.

Since the cabinets and other specific structures such as drawer rails are provided on the inner surfaces of both side plates and the back plate, these plates are not suitable for other uses.

Therefore, the present invention provides a full-open type steel separation trash can while overcoming such problems.
It is an object of the present invention to be used as a confidential document cabinet by replacing the lid provided with a slot with a trash box made of blow panel.

[0015]

FIG. 4 is an explanatory view of FIG. 3, and FIG. 5 is a perspective view of a modification of FIG. 2, that is, a separation trash can.

The sorting trash can of this embodiment is:
The parts common to the separation trash can described in the above-mentioned Japanese Patent Application Laid-Open No. H10-81401, such as the dimensions, the pail, the plastic bag, and the structure of the front door, are omitted or simplified in the drawings and description. It is necessary to replenish these.

First, a confidential document cabinet (hereinafter simply referred to as a cabinet) 1 in which only the trash can lid 5A of the trash can 1A for sorting according to the embodiment of the present invention is changed.
Is outlined.

1, 2, 3, 4, both side plates 2, 2, back plate 3, bottom plate 4, lid (upper lid) of this cabinet 1
Each of the front door 5 and the front door 7 is formed of a panel in which a parison of plastic (for example, low-molecular-weight resin or engineering plastic, but generally PE) is double-wall blown by a press blow method, that is, a blow panel. And has the above advantages.

The cabinet 1 has a long side (width) of about 670 mm, a short side (depth) of about 510 mm, and a height of about 780 mm, and is a medium-sized box body. It is extremely convenient for panel manufacture (inexpensive molds, easy assembly, inexpensive resin, strength retention, weight reduction, inexpensive containers, etc.).

In addition, a single paper storage box 6 is housed in the cabinet 1 so as to be able to be taken out, and when taking out, a so-called full-open type (the entire front door 7 and the cover 5) is used.
Simplicity, and
The side plates 2, 2 and the back plate 3, which are formed by a blow mold avoiding deep drawing, can be fixed on the bottom plate 4 by snap-fitting, and thus these plates (2), (3) are conveniently formed integrally. As a result, not only the productivity is improved, but also the work of snap-fitting the plates (2) and (3) to each other at the time of assembly is omitted.

That is, the back plate 3 is connected between the two side plates 2 and 2 and the connection portion is connected by a hinge portion (not shown) consisting of a solid portion which is partially compressed and formed at the time of press blow. I have.

Here, in particular, the corners of the cabinet 1 (the outer surfaces of the orthogonal corners) are directed to the left and right sides (as viewed from the front door 7) of the two side plates 2 toward the back plate 3 side. Curved portion 8 that forms a circular arc for forming
Are provided, and are connected to the back plate 3 via hinges provided at the outer edge of the end of the curved portion 8, respectively. Therefore, the bent portion 8 having a desired circular design can be formed without bending the hinge. Thus, the cabinet 1 is constituted, and the original advantage of the roundness of the blow panel is further utilized.

Moreover, since the length (width) of the back plate 3 is larger than the length (depth length) of the side plate 2, both have substantially the same size due to the two curved portions 8, so that they have substantially the same shape. Blow
It is convenient for forming panels.

The blow panel has a smooth outer surface.
On its inner surface, there are multiple stages of recesses that are long in the horizontal or depth direction,
Since it is formed by a solid part which has been partially compressed and formed, it becomes double (not possible for injection) and serves as a reinforcing rib, which is comparable to the strength of steel.

In addition, the lid 5 of the cabinet 1 is formed in a rectangular shape in plan view having a long side in the left-right direction (width) and in a shallow dish shape, and the rear side is formed by the upper end surface of the back plate 3. It is hinged by a pin 9 so as to be detachable and is opened rearward (see FIG. 3).

A long horizontal slit-shaped paper inlet 10 is opened in the lid 5, and the paper inlet 10 is opened obliquely downward in a side sectional view provided with a blow panel thickness (about 60 mm). A paper input guide surface 11 is provided in front of the paper input port 10.
Is formed.

For this reason, the paper input user is required to use one or more sheets of confidential paper (for example, folding print paper by a computer).
12 is placed on the paper inlet guide surface 11 and the paper inlet 1
When the security paper 12 is pushed to zero, the confidential paper 12 is dropped in the paper storage box 6 in a substantially horizontal state, and can be stored in a substantially stacked state.

Therefore, since the paper inlet 10 is used, the efficiency of storing the paper in the paper storage box 6 is improved. Further, the confidential paper 12 inside the paper inlet 10 cannot be visually recognized due to the thickness of the blow panel. By reducing the number of times the key 13 of the door 7 is opened and closed, the cabinet 1 for processing confidential documents is suitable.

When a predetermined processing company or person in charge fills up regularly or unloadable, the key 13 is opened, and the front door 7 and the lid 5 are opened to open each key. Take out the paper storage box 6.

In short, the cabinet 1 is suitable for use in the disposal of confidential documents, and the blow panel has a good size and design (such as avoidance of difficulty due to deep drawing and improvement of productivity). In addition, a full-open type structure suitable for a blow panel can be obtained, that is, it is advantageous in terms of use, dimensions, design and structure, and can be a cheap and convenient cabinet. .

Next, it will be described that the trash can 1A can be configured by simply replacing the lid 5 of the cabinet 1 only.

In FIG. 5, the lid 5 of the cabinet 1
5A, the trash can lid 5A shown in FIG.
When the hinges are joined by (see FIG. 3), a separation trash can 1A as shown in FIG.

The trash box lid 5A is formed in a substantially mountain shape, and trash input ports 14 and 15 having specially shaped ports for trash separated on its front inclined surface are opened. These trash inlets 14 and 15 open a rectangular window 16, and this window 1
6, a short cylindrical body 17 having a large-diameter inlet and a small-diameter outlet and a short-square cylindrical body 18 having a large-diameter inlet and a small-diameter outlet are detachably fixed.

If sand or iron sand is easily put between the double walls of the bottom plate 4 of the sorting trash box 1A, a weight is obtained, which is convenient for outdoor use.

Next, the details of the cabinet 1 and the sorting trash can 1A will be outlined.

In the drawing, the front door 7 has two doors which are hinged to each other by means of a concave / convex fitting (or pin). Of course, one single opening may be used.
