[0003] A hinge mechanism is provided on one side of the container body covered with a lid, and a hook mechanism is provided on the opposite side so that the lid can be opened and closed freely. In particular, in the above-mentioned hinge mechanism, an article in which the lid can be detached is known, but basically, the pivot shaft on the lid side is pulled out in the axial direction from the bearing hole on the container side. The configuration is adopted.

There is also known a cooler box having a drainage mechanism for discharging water accumulated therein. The drainage mechanism has a double structure, a hole is drilled at the bottom of the main body filled with heat insulating material, and a flanged cylinder (with screws engraved on the inner and outer peripheral surfaces) is inserted into the hole, A packing is interposed in the flange part so that water does not enter the heat insulating part, and a nut is screwed into the cylinder at the outside (bottom) of the main body to fix the cylinder to the main body. Is screwed.

[0005]

The detachment of the lid body in the hinge mechanism of the container body and the lid body is generally realized by laterally moving (rotating axis direction) the lid body with the lid body fully opened. It has a structure that Therefore, when the stored items are taken in and out, the lid is naturally in the fully opened state, and there is a problem that the lid is immediately separated from the container when a lateral force is applied.

Further, the water draining mechanism of the cooler box has many members as described above, which causes an increase in manufacturing cost. Therefore, the present invention proposes a cooler box having a novel hinge mechanism and a drainage mechanism that can be detached.

[0007]

A cooler box according to the present invention comprises a heat-insulating container body and a heat-insulating lid body that is capped on the container body. A hinge mechanism is provided on one side during crowning, and the opposite side is provided. In a cooler box in which a hook mechanism is provided to agitate the lid to open and close the hinge mechanism, the hinge mechanism includes a protrusion protruding from a side edge of the lid, and a side edge of the lid on both side surfaces of the protrusion. A shaft part that protrudes in parallel, a base part on which the projection part is placed at a position corresponding to the protrusion part of the container body, a hole part that serves as a bearing of the shaft part on both sides of the base part, and a hole part Of the container body-side peripheral surface of the container body, the notch portion having a size that allows passage of the shaft portion, and the locking portion that is attached to the protruding portion and is locked to the base portion when the lid body is fully opened. It is what

Further, in the cooler box, in particular, the heat insulating container body is formed of an inner and outer box body and a heat insulating material filled between the inner and outer box bodies, and a peripheral wall reaching the outer box body is formed inside at the bottom of the inner box body. Formed integrally with the box to form the hole,
The bottom surface of the peripheral portion of the hole forming position in the outer box body is recessed from the other bottom portion, the nut body is tightly fitted and mounted in the hole portion, and the resin body is made wider than the inner diameter of the nut body. The present invention is characterized in that a water draining mechanism, which is formed by screwing a water draining plug having a retaining plate portion protruding from the tip thereof, onto the nut body is provided.

Since the shaft portion itself can be inserted into and removed from the hole through the cutout portion, the shaft portion of the lid body can be removed in the direction of removal of the cutout portion during rotation of the lid body. The lid can be attached and detached at a position where the moving operation is possible, that is, a position where the shaft portion can be extracted. Therefore, there is no detachment of the lid body when fully closed or fully opened.

Further, the water removal inside the container body is realized by unscrewing the water removal plug from the nut body, and since the water removal plug is not separated from the container body by the retaining plate portion, there is no risk of loss.

[0011]

Next, an embodiment of the present invention will be described. The cooler box shown in the embodiment includes a container body 1, a lid body 2, a hinge mechanism 3, a drainage mechanism 4, and a hook mechanism 5, and the container body 1 has inner and outer box portions 11, 12.
A heat insulating material 13 is filled in between, and a band mounting portion 14 is provided on a side surface portion of the outer box portion, and a band 15 is mounted so as to be portable. The lid body 2 has a double structure like the container body 1, is filled with a heat insulating material 21, and has a handle 22 which can be raised and lowered and a concave portion 23 which is a storage place when the handle is folded. The container body 1 is formed into a shape that can be crowned. A hinge mechanism 3 and a hook mechanism 5 are attached to the container body 1 and the lid body 2.

The hinge mechanism 3 includes a protrusion 3 provided on the lid 2.
1, the shaft portion 32, and the locking portion 33, the protrusion 31 is made to protrude to one side of the lid body 1, and the shaft portion 32 protrudes to both sides of the tip of the protrusion 31. It was made
It is parallel to the side edge of the lid 2. Further, the locking portion 33 is provided so as to vertically extend to the outer edge of the protruding portion 31, and corresponds to a base portion 34 described later. Further, on the container body 1 side, a base portion 34 and a hole portion 35 are provided at positions corresponding to the projecting portions 31 and the like on the lid body 2 side.
And a cutout portion 36, the base portion 34 corresponds to the protruding portion 31, the protruding portion 31 is configured to be rotatable on the upper surface of the base portion 34, and the lid 2 is fully opened. Sometimes base 3
4 is formed in a shape in which the engaging portion 33 engages with the outer edge of the No. 4. The holes 35 serve as bearings for the shaft 32, and are provided on both sides of the base 34. The notch 36 is formed by removing a part of the peripheral surface of the hole 35 to a size that allows the shaft 32 to enter and leave the hole 35. It is provided on the side edge side.

The water draining mechanism 4 is provided with a recess 41 and a hole 42. The recess 41 is formed by recessing an appropriate bottom portion of the outer box body 12 of the container body 1 from the peripheral portion. Is formed by integrally molding a peripheral wall reaching the recess 41 of the outer box body 11 at a position corresponding to the center of the recess 41 on the bottom of the inner box body 11 by integrally molding the inner box body 11. To form. In addition, nut body 43 and drain plug 4
4 is used as a member, and the nut body 43 has a size that fits tightly in the hole 42 and is fitted and attached so as not to separate from the hole 42. The drain plug 44 includes a screw portion 441 screwed to the nut body 43, a knob head 442 provided at the base of the screw portion 441, and a nut body 43 made of at least resin.
Nut body 4 which is formed of a retaining plate 444 having a tip 443 wider than the inner diameter of
3, a screw 441 is screwed into the nut body 43, and the distal end 443 is press-fitted therethrough.

Further, the hook mechanism 5 may have any structure as long as it can release the connection between the container body 1 and the lid body 2.

Thus, in the above cooler box, when the container body 1 is capped with the lid body 2, the notch portion 36 to the shaft portion 3 are used.
When 2 is pushed into the hole 34, the lid 2 is tilted around the shaft 32 so as to be openable and closable, and the desired food or the like is stored in the container 1 and is used for cold transportation. Particularly, in the lid body 2, the shaft portion 32 is provided with the cutout portion 3 in the state of being pivotally rotated.
Since it is possible to pull out from the hole portion 34 through 6, the lid body 2 can be detached when cleaning the container body 1 or the like. Of course, in the fully opened state, the locking portion 33 does not collide with the outer edge of the base portion 34, the shaft portion 32 does not come out of the hole portion 34, and the lid body 1 can be separated only when the lid body 1 has a specific angle. Therefore, the lid body 2 does not come off from the container body 1 unless care is taken to remove it.

In draining the water, when the water drain plug 44 is unscrewed from the nut body 43 and the knob head 442 is separated from the nut body, the screw hole of the nut body 43 serves as a water passage, and the inside of the container body 1 is closed. Can be drained. In particular, since the distal end portion 443 of the water drainage stopper 44 comes out of the nut body 43, even if water is drained, the water drainage stopper 44 itself does not separate from the container body 1, so that the water drainage stopper 44 is not lost. Moreover, since the hole 42 is formed in the recess 41, the drain plug 44
It is possible to reduce the inconvenience caused by the downward protrusion of the picking head 442. For example, as illustrated in FIG. 7, the leg 16 of the container body 1 can be formed low even if the knob head 442 has a sufficient height in consideration of operability. Also, the hole 44
Can be formed by integral molding of the inner box body 11 and can prevent water from entering the heat insulating material 13 portion from the hole 44, so that a water sealing structure like a conventional cylinder is adopted. There is no need and the number of members can be reduced.

[0017]

As described above, according to the present invention, the lid body is detached from the container body while the lid body is being pivoted, and in view of the function of the lid body when fully opened or fully closed, As a matter of course, since the lid body is not detached at the position where the same state continues, the careless detachment of the lid body is prevented. Moreover, since the hole of the water draining mechanism is formed integrally with the inner box body, a complicated water sealing structure is not required and the number of members can be reduced.
