BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for storing a liquid such as drinking water, and more particularly to an opening / closing structure for a lid of the container.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
For example, when pouring water stored in a container such as a jug into a cup or the like, it is necessary to manually open the lid that covers the spout.

Moreover, it is unsanitary because the lid may be forgotten to be closed after the pouring operation is completed. The present invention has been made by paying attention to the problems existing in the above-mentioned prior art, and the purpose thereof is to enable a lid body to be easily opened, and a lid body in a container which is not forgotten to close. It is to provide an opening and closing structure.

[0004]

In order to achieve the above object, in the invention of claim 1, the lid is balance-connected to the container body, and the lid covers the spout at the non-pouring position of the container body. As described above, at the pouring position, the lid is an opening / closing structure of the lid configured to open the pouring opening.

According to a second aspect of the present invention, a protrusion is provided on the back surface side of the lid, and the lid and the spout rim are brought into contact with each other via the protrusion. In the invention of claim 3, the container has a filtering structure for filtering the liquid in the container body.

[0006]

In the invention of claim 1 having the above-mentioned structure, even if the container body is tilted from the non-pouring position to the pouring position, the lid is not displaced from the balanced position. Therefore, the spout is relatively opened according to the inclination of the container body, and it is not necessary to open the lid as in the conventional case.

According to the second aspect of the present invention, since the lid and the spout are brought into point contact with each other via the projection, even if water is interposed between the lid and the spout, for example. , The surface tension of water is less likely to act. Therefore, the lid is not adsorbed by water, and the opening operation of the lid becomes smooth.

In the third aspect of the present invention, for example, when tap water is poured into the container body, it is filtered by the filtering structure and stored in the container body as filtered water.

[0009]

EXAMPLE An example in which the present invention is embodied in a water supply pot having a filtration structure will be described below.

As shown in FIGS. 1 to 4, a container body 1 made of synthetic resin has a bottomed cylindrical shape, and a filter holder 2 is inserted and fixed in an opening 1α above the container body 1. The container body 1
A spout 3 is formed on the front side (left side in FIG. 1). The tip of the pouring spout 3 is processed to have a square surface.

The handle 4 is provided on the upper part of the back surface (right side in FIG. 1) of the container body 1. A water inlet 2α is formed on the upper surface of the filter holder 2, and a cartridge locking portion 2β is formed on the inner peripheral edge thereof.

As shown in FIG. 1 and FIG. 2, the filter cartridge 5 as a filtering structure comprises an outer filter 5α and an inner filter 5β. The activated carbon 5γ is housed in the space formed between the outer filter 5α and the inner filter 5β. Then, the outer filter 5α and the inner filter 5β are integrated with a stopper 5δ and locked to the cartridge locking portion 2β of the filter holder 2.

In FIG. 2, reference numeral 6 denotes an upper lid for covering the water inlet 2α, which can be attached / detached for attaching / detaching the filter cartridge 5 and for injecting water into the water supply pot. And
As shown in FIG. 3, the filter holder 2 is provided with a lid 7 that covers the spout 3 and has the same shape as the outer shape of the spout 3, and the lid 7 corresponds to the inclination of the container body 1. It is designed to be opened. That is, a pair of bearing portions (only one of which is shown in the drawing) 14 are integrally formed on the back surface of the filter holder 2 on the spout 3 side. The substantially U-shaped support arm 11 is fixed to the back surface of the lid 7. The support arm 11 is rotatably supported by the bearing portion 14 by a support shaft 12. Balance weight 1
3 is connected to the support arm 11 via the support shaft 12 on the opposite side of the lid 7. The recess 10 is formed at the end of the filter holder 2 and can accommodate the balance weight 13.

As shown in the enlarged view in the circle A of FIG. 1, the projection 15 is provided on the rear surface of the front end portion of the lid body 7,
Is abutted against the spout 3 with the same projection 15. Now, in order to store water in the main water supply pot, first, the upper lid 6 is removed and water is poured from the water inlet 2α. The water that has been poured into the filter cartridge 5 is the inner and outer filters 5α, 5
It is filtered by β and activated carbon 5γ, and is thus stored as filtered water in the water supply pot. When the upper lid 6 is closed, the lid 7 is held in the closed state by the weight of the balance weight 13 as shown in FIG.

Here, in order to pour the filtered water stored in the water supply pot into, for example, a cup (not shown), the handle 4 may be gripped and the water supply pot may be tilted. At this time, as shown by the chain double-dashed line in FIGS. 4B and 3, the lid 7 tries to hold the position by the weight of the balance weight 13 with respect to the container body 1 in the inclined state.
The spout 3 is relatively opened according to the inclination of the container body 1. Therefore, the filtered water is poured into the cup through the spout 3. The surface of the spout 3 (inner surface)
Since the water is treated on the corner surface, it is possible to prevent the filtered water from collecting at this corner portion and the trace of water discharged from the pouring port 3 to be in a diffused state.

Further, as shown in FIG. 4A, after the pouring operation is completed, the water supply pot is returned to the upright position, and as a result, the lid 7 covers the spout 3. The present embodiment having the above configuration has the following effects. The lid 7 and the balance weight 13 are at the supporting position (the support shaft 1
Weight balance is balanced with 2) as a fulcrum. Since the lid 7 is hardly displaced with respect to the inclination of the container body 1, as a result, the spout 3 is opened.
Therefore, the cumbersome operation of opening the lid 7 during the pouring operation is released. Further, if the container body 1 is returned to the upright position, the lid body 7 closes the spout 3 as a result, so that the lid body 7 is not forgotten to be closed, which is hygienic. A protrusion 15 is formed on the rear surface of the tip of the lid 7, and the lid 7 and the edge of the spout 3 are in point contact with each other via the protrusion 15. For this reason, the lid 7 is in a state of slightly floating above the edge of the spout 3, and it is possible to prevent the lid 7 from being adsorbed by the surface tension of the water attached to the edge of the spout 3. Therefore, the lid 7 can perform a smooth opening operation. Since the water supply pot of this embodiment has the filtering function (5), the filtered water is stored in the water supply pot only by pouring water. Further, this filtration function is detachable because it has a cartridge structure, and its replacement is easy. The weight balance between the lid 7 and the balance weight 13 is balanced at a position where the two 7 and 13 are further rotated counterclockwise from the state shown in FIG. Therefore, even if the water supply pot is in the upright state, a force is applied to the lid body 7 to return to the balance equilibrium position, that is, the lid body 7 is rotated to the left side in FIG. It Therefore, the lid 7 is pressed against the edge of the spout 3, and the closed state of the spout 3 is stabilized.

The following embodiments can be carried out without departing from the spirit of the present invention. (1) The present invention is embodied in a container for storing other liquids such as liquid seasonings, oils or liquid detergents other than water. (2) Delete the filter cartridge 5 configuration.
Also, the activated carbon 5γ is deleted, and one filter 5α (5
Be composed of only β). In this case, the filter 5α
Let (5β) retain tea leaves. In this way, tea is stored in the water supply pot by pouring hot water or water from the water inlet 2α. Moreover, since the filter is removable, used tea leaves can be easily discarded. (3) Providing a plurality of protrusions 15.

The technical idea which can be understood from the above embodiment will be described. (1) The lid opening / closing structure according to claim 3, wherein the filtration structure 5 is a cartridge structure that is attachable to and detachable from the container body 1.

This makes the replacement of the filtration arrangement 5 convenient. (2) The balance position of the weight balance of the lid body 7 is located at a position where the lid body 7 is further rotated in the closing direction from the closed state of the spout 3 by the lid body 7. Opening / closing structure of the lid described in.

In this way, the closed state of the spout 3 is stabilized.

[0021]

According to the invention of claim 1 having the above-mentioned structure, it is not necessary to perform the opening operation of the lid, and the operation is released from the troublesome operation. In addition, it is hygienic because it does not forget to close the lid.

According to the second aspect of the present invention, for example, the lid body is not adsorbed by the surface tension of water, and the opening operation of the lid body becomes smooth. According to the invention of claim 3, since it has a filtering function, impurities in the liquid can be removed.
