[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a trash container having an opening / closing lid on the top, and more particularly to a trash container that opens and closes the lid by applying the lever principle.

[0002]

[Prior Art]

 Conventionally, there are two types of general garbage containers with an opening / closing lid, which are made of iron plate and plastic. This general iron plate waste container requires multiple processings such as bending and pressing from the plate material, which requires a lot of time and labor. In addition, since the iron plate material has a heavy weight, the freight and labor required for transportation were great. Due to these factors, iron plate waste containers increase the unit price of the product and require a large amount of unnecessary spending, so plastic waste containers have become the mainstream in recent years.

As shown in the sectional view of FIG. 5, this plastic garbage container has an inner container d inside an outer container a and an opening / closing lid c above the outer container a. It has a tread b on the bottom. An annular connecting member e having a hole f is provided at the upper end of the foot of the tread b, and a connecting member h having a hole i is provided on the support side of the opening / closing lid c. A connecting rod g is provided between the tread b and the opening / closing lid c, and both ends of the connecting rod g are engaged with the holes f and i to connect the tread b and the opening / closing lid c.

When the end portion of the tread b is pressed, this garbage container opens the opening / closing lid c upward via the connecting rod g by the application of the lever principle by the fulcrum j provided substantially in the center of the tread b. It is a thing. When the pressing force on the tread b is removed, the weight of the opening / closing lid c automatically closes the outer container a.

[0005]

However, in the above structure, the connecting member e provided at the upper end of the tread b for connecting both ends of the connecting rod g and the connecting member h provided on the supporting side of the opening / closing lid c are connected. Since a force is applied each time the opening / closing lid c is opened / closed, a concentrated force acts around the hole f of the connecting member e and the hole i of the connecting member h, respectively. Further, when the opening / closing lid c is opened, the opening / closing lid c is opened while supporting the weight of the opening / closing lid c around the hole i, so that more concentration force is exerted. In addition, the area receiving this concentrated force is small only around the hole i, and furthermore, the plastic material itself lacks durability and has fragile properties. For these reasons, when the above concentrated force is frequently applied due to repeated opening and closing operations, the periphery of the hole f or the hole i may be damaged.

If the periphery of the hole f or the hole i is damaged, it is difficult to repair the above-mentioned conventional garbage container made of metal, and the entire garbage container is discarded. In this way, in the case of the conventional garbage container, if it is damaged, the entire garbage container is discarded, so that the garbage container itself becomes garbage, and the phenomenon of creating garbage occurs.

Further, as another drawback, the connecting rod g is provided inside the outer container a, but the space inside the outer container a is limited, and the length of the tread b is also limited. Therefore, even if the tread b is made as long as possible, the vertical movement distance is small due to the lever principle, and this makes it impossible to open the opening / closing lid c widely. This opening angle is well below the vertical (90 °) (see Fig. 5), which makes it inconvenient for the user to simply clean the inner container d and discharge any debris that has accumulated inside. It did not stop, and it was inconvenient to put garbage in the garbage container.

In view of the above problems, an object of the present invention is to provide a garbage container with an opening / closing lid, which has a simple structure and is durable, and which can open the opening / closing lid widely.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the waste container with an opening / closing lid according to the present invention includes an outer container having an open upper surface, an inner container having an open upper surface and vertically movable in the outer container, and one end of the outer container upper end. A waste container with an opening / closing lid that is pivotally attached to and opens and closes on the lower part of the outer container, and a tread plate is provided swingably on the lower part of the outer container. The inner container is pushed up, and the upper end of the inner container opens the opening / closing lid as the inner container rises.

[0010]

[Action]

 With the above structure, before the operation, the inner container is housed in the outer container, and the opening / closing lid pivotally attached to one end of the upper part of the outer container closes the upper surface of the outer container.

On the other hand, at the time of operation, by pressing the end of the tread, the tip of the tread pushes the inner container upward by applying the lever principle. Along with the movement of the inner container, the inner container moves with the upper end of the inner container in contact with the inner surface of the opening / closing lid to open the opening / closing lid. This movement of the inner container pushes the pivot side of the opening / closing lid upward, so that the opening / closing lid can be largely opened.

[0012] With this, it becomes easy to put dust in the dust container, and it becomes possible to easily take out the inner container and discard the dust inside, and at the same time, return the inner container to the original state. It will also be very easy.

Further, since the structure is simple, problems such as breakage are extremely reduced.

【Example】

 Hereinafter, a structure of an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view showing the whole trash container with an opening / closing lid, and FIG. 2 is a perspective view showing the whole. In the following description, the side where the tread is located is the front side and the side where the pivot point of the lid is located is the back side.

As shown in the figure, the main components of the waste container with an opening / closing lid are an outer container 1 with an open upper surface, an inner container 2 that can be accommodated in this outer container 1, and an upper part of the outer container 1 above. It is composed of an opening / closing lid 3 that is pivotally attached to one end to open and close, and a tread 11 that opens and closes the opening and closing lid 3. Each of these constituent members is manufactured as an integrally molded plastic product.

The outer container 1 is a cylindrical body having an open upper surface and a bottom plate, and an upper edge flange portion 14 is formed on the upper edge thereof. A supporting member 13 for pivotally supporting the opening / closing lid 3 is provided at one end on the upper rear side of the outer container 1, and the supporting member 13 is U-shaped in a plan view in which the left and right sides are connected by the reinforcing member 132. On both outer surfaces of the upper part, projections 131 are provided as fulcrums when the opening / closing lid 3 is opened and closed. Since the protrusion 131, which serves as a fulcrum of the opening / closing lid 3, is provided at a position projecting from the upper edge of the outer container 1, the opening / closing lid 3 completely covers the upper surface of the outer container 1.

In addition, a concave space 123 is provided in the lower portion on the front side of the outer container 1, and a holding member 12 for installing the tread 11 in this space 123 is formed from the outer periphery of the outer container 1 toward the center of the container. Has been done. The holding member 12 has an open upper surface, and both side walls thereof are formed with an inclination that becomes lower than the outer peripheral portion toward the central portion, and a U-shaped notch portion for holding the tread 11 at a predetermined position on the upper edge thereof. 121 are formed. The protrusion 113 provided on the tread 11 is engaged with the notch 121 to hold the tread 11 so that the tread 11 serves as a fulcrum. Further, the stability of the holding member 12 is measured by providing a reinforcing member 122 near the cutout 121.

The inner container 2 is a container in which a bottom plate is provided on a cylindrical body having an open upper surface, and a flange portion 21 projecting from the outer periphery is provided at a predetermined position near the upper end. This is because when the inner container 2 is placed in the outer container 1, the flange 21 abuts the upper edge flange 14 of the outer container 1 so that the inner container 2 does not slide down to the bottom of the outer container 1. I have to.

In addition, a projecting portion 22 that projects upward is provided at two locations on the upper edge of the inner container 2, and a hole 221 is provided in this projecting portion 22 and a semicircular shape is formed in this hole 221. The end of the handbag 23 is attached. Further, by providing ribs 24 of appropriate length downward from the collar portion 21 at appropriate places outside the inner container 2 (four places in this figure), the container itself is strengthened and stability is improved. I keep it.

The opening / closing lid 3 has a circular shape with its periphery bent, and a supporting portion 31 protruding outward is provided on the back side thereof, and holes 33 are formed on both side surfaces thereof. The opening / closing lid 3 is pivotally attached to the hole 33 as a fulcrum by fitting the projection 131 provided on the support member 13 of the outer container 1 into the hole 33.

A recess 34 is formed inside the support portion 31. The width direction of the recess 34 is formed to be slightly wider than the outer width of the support member 13 of the outer container 1, and when the opening / closing lid 3 is opened, the upper part of the support member 13 is inserted into the recess 34 and is completely opened. It is designed to stop at a high place. Further, a semicircular rib 341 is attached to an appropriate position on the back surface side of the recess 34 to strengthen and stabilize the recess 34.

Further, in this embodiment, two substantially triangular guide members 32 are arranged at predetermined positions on the back side of the inner wall of the opening / closing lid 3. The two guide members 32 are connected to each other by a reinforcing member 323, so that the guide member 32 is reinforced and stable. An upper edge 321 of the guide member 32 is formed perpendicularly to the opening / closing lid 3, and a guide surface 322 is formed in an arc shape curved inward. The function of this guide surface 322 is that when the inner container 2 is pushed up by the force from the tip of the tread 11, the upper edge of the inner container 2 contacts this guide surface 322, and the inner surface of the inner container 2 is inwardly contacted while being touched. It gradually moves along a curved arc, and the opening / closing lid 3 is gradually opened with this movement. The opening / closing lid 3 is smoothly opened, and at the same time, the opening / closing lid 3 is opened to a substantially vertical angle.

The tread plate 11 has an L-shaped cross section, and has a foot pressing part 111 formed at the front end thereof and a protruding part 112 protruding upward at the rear end thereof. .. Further, one projection 113 is provided at a predetermined position on each side surface of the tread plate 11. The tread 11 is held by fitting the protrusion 113 into the notch 121 formed in the holding member 12 of the outer container 1 described above. Further, the protruding portion 112 formed at the rear end portion supports the above-described inner container 2 in a stable state from below and also functions to push up or down.

Further, in this embodiment, since the rear end of the tread 11 pushes up substantially the center of the inner container 2, the protrusion 112 is provided at the rear end of the tread 11. The pressing force can be immediately transmitted to the bottom of the inner container 2.

The operation of the waste container with an opening / closing lid according to the present invention having the above structure will be described below with reference to the drawings. FIG. 3 is a sectional view showing a state before the operation, and FIG. 4 is a sectional view showing a state after the operation.

As shown in FIG. 3, in the state before the operation, the tread plate 11 is held by the holding member 12 of the outer container 1, and the treading portion 111 is in a certain angle inclined upward. .. In this state, the upper part of the projecting portion 112 at the rear end of the tread 11 is just in contact with the bottom of the inner container 2. This state is the calm state of the waste container itself according to the present invention, and at this time, the lower surface of the collar portion 21 near the upper end of the inner container 2 contacts the upper edge collar portion 14 of the outer container 1, Further, the periphery of the movable lid 3 is also covered with the upper edge flange portion 14 of the outer container 1.

On the other hand, as shown in FIG. 4, in the state after the operation, an external force is applied to the treading portion 111 of the tread 11 to press the treading portion 111 downward, so that the protrusions 113 on both side surfaces of the tread 11 are supported. As a point, it acts to move the protrusion 112 at the tip of the tread 11 upward by the principle of leverage. Along with the movement of the protrusion 112, the inner container 2 inserted along the inner edge of the outer container 1 is pushed up by the protrusion 112, and the upper end of the inner container 2 is gradually formed into a substantially triangular shape provided on the movable lid 3. The lid is pushed up along the arcuate guide surface 322 of the guide member 32, and finally the recess 34 of the opening / closing lid 3 comes into contact with the support member 13 of the outer container 1. In this state, the inner container 2 is pushed up moderately high, and the opening / closing lid 3 is opened to an angle almost vertical.

As described above, it is possible to easily open the opening / closing lid 3 to almost the vertical position by stepping on the treading portion 111 of the tread plate 11. Therefore, it is easy to throw dust into the inner container 2. Yes, it is possible to easily remove the inner container 2 and dispose of the dust inside, and at the same time, it is very easy to return the inner container 2 into the outer container 1.

In the above-described embodiment, by providing the guide member 32 having the curved guide surface 322 on the inner surface of the opening / closing lid 3, the opening / closing lid 3 can be smoothly moved to a nearly vertical angle as the inner container 2 rises. Can be greatly opened up to.

Further, as means for swingably providing the tread plate 11, it is possible to swing the tread plate 11 by engaging projections 113 provided on both sides of the tread plate with a notch 121 of a holding member 12 provided at a lower portion of the outer container 1. However, it is also possible to form a projecting portion in the lower part of the tread 11 and pivotally attach this projecting portion so as to be swingable, and there is no particular limitation.

Furthermore, in the above embodiment, the outer shape of the container is formed into a circular shape, but it may be a square shape or the like, and the shape is not particularly limited, and may be any value in consideration of aesthetics, compactness, ease of assembly, and the like. The shape may be determined.
