Description

[Detailed Description of the Invention] [Field of Application] The present invention relates to a container with a lid, particularly a container with a lid installed in a corner of a toilet or the like.

[Prior art and its problems] As a container with a lid as described above, the fourth type has already been developed.
The one shown in the figure is used. In this case, a swingable lid body 2 is attached to an opening 21 of a lid frame 20 that covers the opening of the container main body 1.

In this conventional device, the gravity balance of the lid 2 with respect to the pivot support 22 is set to a predetermined value, so that the lid 2 is always in a closed state.

Therefore, if the opening force is released after opening the lid 2 and throwing waste etc. into the container main body 1, it will automatically close, causing the inconvenience of leaving the lid 2 open. does not occur.

However, in this conventional device, although the lid body 2 is always kept in a closed state, the closed state is unstable and a large amount of odor leaks from the stored items.

This is because the lid 2 is configured to be closed by its own unbalanced weight, so a large gap must be provided between the pair of the lid 2 and the lid frame 20.

To solve this inconvenience, a device incorporating a locking mechanism for biasing the container in the opening direction and maintaining the lid in the closed state was developed in U.S. Patent No. 48-76062.
This method is disclosed in Japanese Utility Model Publication No. 52-12498.

In these products, the locking mechanism allows the lid to be stably maintained in a closed state, and the gap between the lid and the main body in this closed state can be extremely reduced, making it difficult for the odor of the contents to leak out. Become something.

However, this prior art device has the disadvantage that the locking mechanism is complicated, and when used for a long period of time, the locking portion of the locking mechanism wears out and cannot be maintained in the closed state. arise.

The present invention is designed to make it easy to open and close the lid 2 and to ensure that the lid 2 is in a closed state in such a "container main body 1 whose opening is closed by the lid 2". Furthermore, the technical problem is to improve the durability of the opening/closing mechanism of the lid body 2.

[Technical Means] The technical means of the present invention taken to solve the above-mentioned technical problems is as follows. The tip of the arm 23 is pivotally supported by the inner circumferential wall of the open portion of the container main body 1, and the first magnetic body 24 is attached near the periphery of the lid body 2 at a position away from the arm 23,
A cavity 13 that opens only upwardly and outwardly is formed on the inner circumferential wall of the open upper end of the container main body 1 and at a position facing the first magnetic body 24.
A magnetic body 11 is provided so as to be able to rise and fall freely and is biased in the upward direction, and a projection piece 1 for operation is attached to this second magnetic body 11.
2 is attached, and this protruding piece 12 is made to protrude outside from the upper part of the container main body 1, and the first magnetic body 24 or the second
Either one of the magnetic bodies 11 is a permanent magnet, and the length of the arm 23 and the first magnetic body 24 are set so that the periphery of the lid 2 and the upper edge of the container main body 1 are in contact with each other when the lid 2 is closed. , the mounting position of the second magnetic body 11 was set.

[Operation] The above technical means of the present invention operates as follows.

When the lid 2 is open, a biasing force in the opening direction is applied to the lid 2, so that the lid 2 is maintained in the open state. Next, when the lid 2 is closed, the periphery of the lid 2 comes into contact with the periphery of the open upper end of the container main body 1, and in this state, the first magnetic body 24 and the second magnetic body 11 come into contact with each other. Since one of them is a permanent magnet, the first magnetic body 24 and the second magnetic body 11 are attracted to each other, and the periphery of the lid 2 is in contact with the upper periphery of the container main body 1. At the same time, the opposing portions are pressed against each other by a force corresponding to the attractive force of the permanent magnet.

In this state, the upper open part of the empty chamber 13 is closed by the first magnetic body 24, so even if a part of the empty chamber 13 is opened to the outside, the container closed by the lid 2 The interior of the main body 1 is kept substantially sealed.

Next, from this state, when the protruding piece 12 attached to the second magnetic body 11 is pushed down, the first magnetic body 24
and the second magnetic body 11 are separated, and the first
The attraction force between the magnetic body 24 and the second magnetic body 11 disappears, and the lid 2 is automatically opened by the urging force acting on the lid 2.

[Effects] Since the present invention has the above configuration, it has the following unique effects.

When the lid body 2 is closed, the inside of the container main body 1 is reliably closed and maintained in this state. It becomes difficult for odor to leak out.

The mechanism for opening the lid 2 in the closed state simply urges the lid 2 in the opening direction and holds the second magnetic body 11 of the container main body 1 so that it can move up and down. The structure is simpler than that which maintains the lid body 2 in a closed state using a complicated engagement mechanism such as the conventional one. Moreover, since the lid body 2 is maintained in the closed state by mutual attraction of the first and second magnetic bodies, rather than using an engagement mechanism,
Even when opened and closed repeatedly, the function of the holding mechanism for maintaining the closed state does not deteriorate. In other words, the durability is improved.

Furthermore, since a claw mechanism unlike the prior art is not used as a mechanism for maintaining the lid 2 in the closed state, safety in the open state of the lid 2 is improved. Therefore, there is no risk of getting your hands caught by your fingernails when taking out the contents such as filth.

[Example] Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3.

In this embodiment, as shown in FIG.
is a main body part 1a and a frame body part 1b attached to the opening part.
As shown in FIG. 1, the frame portion 1b is fitted into the open upper end portion of the main body portion 1a and integrated.

At the upper end of the inner periphery of this frame body part 1b, a bearing part from which the shaft 14 projects horizontally is formed, and on the opposite side there is formed a square cylinder 1 which is open upward and has a bottom.
5 is formed, and the inside of this rectangular tube 15 becomes a cavity 13. This rectangular tube 15 is connected to the inner circumferential wall of the frame portion 1b, and an opening 16 is formed in the inner circumferential wall contained within the cavity 13.

Further, the second magnetic body 11 is a permanent magnet, and this second magnetic body 11 is a permanent magnet.
The magnetic body 11 is attached and fixed to the upper end of the elevating body 17 which is held in the empty chamber 13 so as to be movable up and down.
A spring 18 is interposed between the bottom wall of 5 and this elevating body 17. Furthermore, the projecting piece 12 is integrally formed with the elevating body 17 and protrudes outside from the opening 16, thereby regulating the highest position of the elevating body 17, that is, the second magnetic body 11, to be constant.

Next, as the shaft support structure of the lid body 2, the frame body portion 1b
A structure is adopted in which the shaft 14 protruding in a cantilevered state from the arm 23 is fitted into a horizontal hole 25 formed at the tip of the arm 23, and a snap spring 26 is attached to the portion of the shaft 14 protruding from the horizontal hole 25 to attach the lid body. A biasing force in the opening direction always acts on the opening 2.

In this case, as shown in FIG. 3, a recessed groove 19 is formed in the portion of the shaft 14 where the snap spring 26 is attached, so that the lid body 2 is held in a fixed state by the attachment of the snap spring 26.

In the above embodiment, as shown in FIG.
In the closed state, due to the described action, the peripheral edge of the lid body 2 is held in a closed (sealed) state in contact with the upper end surface of the frame body part 1b, and when the protrusion piece 12 is pushed down against the spring 18, As shown in FIG. 1, the second magnetic body 11 and the first magnetic body 24 are separated, and the lid body 2 is opened by the action of the snap spring 26.

In this embodiment, the handle 3 is attached to the frame body part 1b, and the center part of the handle 3 is set to abut against the protruding piece 12, so that the lid body can be moved by pressing down the handle 3. 2 can be released,
The opening operation of the lid body 2 becomes even easier.

Alternatively, the first magnetic body 24 may be a permanent magnet, and the second magnetic body 11 may be a magnetic body such as a piece of iron that is attracted to the second magnetic body 11.
