Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container with a lid that opens and closes on a hinge, and more specifically, in a container with a lid that opens and closes on a hinge, such as a heated cooked rice container called an electronic jar, the lid is attached to the container body. This invention relates to a container with a lid configured to be rotatable in a horizontal plane.

In conventional containers with hinged lids, such as heated rice containers, one end of the lid is pivoted to the container body, and the lid is rotated in an arc in a vertical plane to close the lid. When opening the body, if the lid locking device is in the opposite position to the body, either lift the entire lidded container to change the position of the lid handle, or turn your body toward the lid locking position. There was an inconvenience that the body had to be operated to open the body, which made the operation complicated. In addition, when changing the position of a container with a lid, it may move on the floor, causing wrinkles in the tablecloth on the dining table and requiring effort to correct them. Sometimes it hurt my face. The present invention is an attempt to solve the problems of the conventional containers with lids described above, and the present invention is designed to cover the container body with a lid rotatable in a horizontal plane so that the handle position of the lid can be changed as appropriate. The object of the present invention is to provide a container with a lid that can be opened and closed using a hinge.

Hereinafter, the hinge-opening/closing lidded container of the present invention will be explained based on the illustrated embodiments. The embodiments shown in FIGS. 1 to 3 show a heated cooked rice container called an electronic jar. This heat-insulating container is composed of a container body 1, a lid unit 3, and an annular shoulder village 4. The container body 1 is composed of an outer case 11 forming the outside and an inner container 15 forming the inside. A heat-retaining heater 18 is provided around the upper end of the outer periphery of the inner container 15 between the inner container 15 and the inner container 15 . In addition, the outer case 11 has an outer plate 13 and a reinforcing plate 14.
The outer case 11 has a double-walled structure, and the outer peripheral portion 12 at the upper end of the outer case 11 has a small diameter. Note that the upper end of the inner container 15 is a flange 16 formed by projecting outward, and the inner container 15 has a flange 16 extending outward from the outer case 11.
A container body 1 is formed by being fixed to the upper end of the container. Further, an annular guide portion 21 is attached to the outer case 11 of the container body 1 around the periphery 12 of the outer upper end thereof. This guide member 21 is formed by installing a plurality of sliding protrusions 23, 23, . It is fixed to the outer case 11. The lid unit 3 consists of a lid 31 and a handle 32 formed across the diameter of the lid 31. Both ends of the handle 32 are integrally fixed to the lid 31. A hinge portion 33 is formed at the rear of the handle 32 .
A locking member 34 is provided at the front part.

Further, an inner cover 35 supported by a center pin 36 is provided on the lower surface of the cover 31, and the inner cover 35 is rotatable relative to the cover 35 via a sliding member 37 such as a thrust bearing. It has become. Note that this thrust bearing 37 is
When the lid unit 3 is closed in the container body 1 and the lid unit 3 is rotated relative to the container body 1 with the outer circumferential green 35a of the inner lid 35 resting on the shoulder 16 of the inner container 15. Second, this is to prevent the inner lid 35 from rotating with the lid unit 3. The shoulder village 4 is constituted by an annular base 41 whose inner diameter is slightly larger than the outer diameter of the outer upper end of the outer case 11, and a hinge receiving portion 44 is provided on a part of the upper surface of the base 41. It is being

Further, the base 41 is formed with a claw receiving portion 45 for locking the claw piece 34a of the lock portion 34 of the lid unit 3 at a position opposite to the hinge receiving portion 44 thereof. Furthermore, base 4
1 is formed with a circumferential groove 46 on its inner circumferential surface 42, in which the guide member 21 is rotatably played, and on the upper circumferential surface within the circumferential groove 46, a sliding protrusion 23 of the guide member 21 is formed. A receiving groove 47 is formed to slidably engage with the receiving groove 47. The container body 1, shoulder member 4, and lid unit 3 are combined as follows.

That is, the shoulder member 4 has the guide member 21 of the container body 1 rotatably fitted in its circumferential groove 46 in a loose state, and the lid unit 3 has its hinge portion 33 fitted in the shoulder member 4. It is coupled to the hinge receiving portion 44 by being pivotally mounted via a pin 39. In the heat-insulating container of this embodiment, the shoulder section 4 is rotatably attached to the guide member 21 in a horizontal plane, and the lid unit 3 is pivotally mounted on the shoulder member 4 by a hinge pin 39. Therefore, the lid unit 3 is also rotatable in a horizontal plane relative to the container body 1.

FIG. 4 shows an external view of another embodiment of the present invention.
In the overflow container of this embodiment, the container body 1 has a stepped protrusion 2 on the upper surface around the outer upper end of the outer case 11.
An annular guide member 2 in which a plurality of tanks 3 are installed at regular intervals.
1 is fixed.

A shoulder member 4 is rotatably mounted on the guide portion 21, and a lid unit 3 is provided above the shoulder member 4, which is pivotally connected by a hinge pin 39. Further, the lid body 31 of the lid unit 3 has the guide member 2 on the outer periphery of its lower surface.
An annular groove 51 for slidingly competing the protrusions 23 of 1
is formed. Further, the shoulder member 4 is provided at the joint edge of the outer case 11 and the inner container 15 that form the upper end of the container body 1, and the shoulder member 4 connects the outer case 11 and the inner container 15.
You should combine them. The other structure of the heat-insulating container shown in FIG. 4 is constructed similarly to the structure of the heat-insulating container shown in FIG. 1, so the explanation thereof will be omitted. In the heat-retaining container shown in FIG. 4, the annular groove 51 formed on the lower surface of the lid unit 3 is joined to the protrusion 23 of the guide member 21 fixed to the container body 1 side, and the lid unit 3 is pivotally mounted via a hinge pin 39 on the shoulder member 4 rotatably mounted on the guide member 21, so that the lid unit 3 can be rotated in a vertical plane using the hinge pin 39 as a fulcrum. At the same time, it is rotatable in a horizontal plane relative to the container body 1.

Although the guide member 21 is an annular ring body,
As shown in FIG. 5, a plurality of them may be arranged at regular intervals around the outer upper end of the outer case 11.

In this case, the sliding protrusions 23 are provided on each guide member 21, respectively. FIG. 6 shows a guide member 21 in yet another embodiment of the invention.

In this guide member 21, a sliding rail 23' is provided on the upper surface of the guide member 21 instead of the sliding protrusion. In yet another embodiment, the shoulder village 4 may be directly supported by the guide member 21 without providing the guide member 21 with any truss or seal (FIG. 7). FIG. 8 shows the shoulder member 4 without an annular shape, and the hinge portion side end of the handle 32.

An example is shown in which it is provided at the end of the rack device. It should be noted that the hinge-opening/closing lidded container of the present invention is not limited to the cooked rice heat-insulating container of the above-mentioned embodiment, and furthermore, it goes without saying that the design of the container can be changed as appropriate within the scope of the claims.

Next, to explain the effects of the present invention, the container with a hinged opening/closing type lid of the present invention has a guide member 21 on the upper part of the container body 1.
Furthermore, since the shoulder village 4 with one end of the rhombus pivotally attached to the guide member 21 is rotatable in the horizontal plane, the lid unit 3 is also rotated in the horizontal plane with respect to the container body 1. When opening the lid unit 3 by rotating it in an arc in a vertical plane at the pivot point, the entire lidded container can be repositioned even when the lid locking section 34 is in a far position, or the lid can be moved freely by the user's body. Since there is no need to move the lid unit 3 and only the lid unit 3 needs to be rotated within a horizontal plane, the labor is reduced and the lid unit 3 is convenient and easy to use.

Furthermore, unlike conventional containers with lids, there is no need to change the position by sliding on the dining table surface, so there is no possibility that the tablecloth, etc. on the dining table surface will rotate and the tableware etc. on the table cloth will fall over. This has the effect of not damaging the floor or table surface.
