DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a rice bin having an insect repellent function.

[0002]

2. Description of the Related Art It is well known that pepper fruits themselves are directly introduced into rice in ordinary households as a repellent measure against rice worms (cereal elephants) generated in rice bins.

[0003]

However, even if the pepper is embedded in the rice, the insect repellent effect is low, and it takes time to remove the pepper from the rice when the rice is taken out from the rice bottle and washed. It was not possible to determine from the outside whether or not the insect repellent effect period of the pepper had expired.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems. The use of a volatile insect repellent provides an excellent insect repellent effect, and the arrangement of the insect repellent in a rice bottle is improved. An object of the present invention is to provide a rice bin that can enhance the insect repellent effect by stiffening and, when the insect repellent function deteriorates, can be easily replaced with a new insect repellent. Another object of the present invention is to provide a rice bin that can be used to simplify the confirmation when the insect repellent function has deteriorated.

According to the first aspect of the present invention, a rice input port is formed on an upper surface of a rice bin main body, and the rice input port is closed and opened by an upper cover. A bag storage chamber is formed on the back side, and an insect repellent bag containing a volatilized insect repellent is stored in the bag storage chamber so as to be able to be taken in and out, and a vent hole communicating with the rice bin body in the bag storage chamber. Is formed.

In the invention according to a second aspect, a rice inlet is formed on the upper surface of the rice bin main body, and the rice inlet is openably closed by an upper lid, and a transparent portion is formed in a part of the upper lid. At the same time, a bag storage chamber is formed on the back side of the transparent part, and inside the bag storage chamber, an insect-repellent bag capable of internally seeing through the insect repellent which is discolored by the volatilization of the medicine is stored so as to be able to be taken in and out. In the bag storage chamber, a vent hole communicating with the rice bin main body is formed.

According to a third aspect of the present invention, in the first or second aspect of the present invention, a release hole for allowing adults to escape to the outside is provided in a front wall of the rice bin main body.

[0008]

According to the first aspect of the present invention, the volatile insect repellent stored in the bag storage chamber on the back side of the upper lid is uniformly spread over the rice from above the rice in the rice bin body through the ventilation hole. It will increase the insect repellent effect on rice as a whole.

According to the first aspect of the present invention, a bag storage chamber is formed on the back side of the upper lid, and the insect repellent bag is stored in the bag storage chamber. The agent can be prevented from adhering to the back surface of the transparent portion, so that the insect repellent can be prevented from interfering with the volatilization caused by the adherence, and a good volatilization state can always be expected.

Further, according to the first aspect of the present invention, the insect repellent is stored in the rice lid main body so as to be able to be taken in and out of the upper lid which can be opened and closed, so that the replacement operation can be easily performed by opening the upper lid.

According to the second aspect of the present invention, a transparent portion is provided on the upper lid which always opens and closes the rice inlet when replenishing rice, and the discoloration due to the volatilization of the insect repellent from the outside through the transparent portion. Because it is possible to peek at the state,
Every time the rice is replenished, it is easy to notice, and it is easy to confirm the reduced state of the insect repellent function of the insect repellent and to prompt the replacement.

According to the third aspect of the present invention, since the escape hole for allowing the adult to escape to the outside is provided in the front wall of the rice bin main body, the dead adult hardly remains in the rice.

A rice weighing operation button 8 is provided below the rice weighing operation button 7 on the front wall 6 and is a rice tray provided so as to be able to be pulled out below the rice weighing operation button 7.

The upper lid 4 includes a top plate 4a and the top plate 4a.
And a peripheral side plate portion 4b formed on the periphery of the top plate 4a, and the insect repellent 10 is stored and arranged on the back side of the top plate 4a as described later. FIG.
As shown in FIG.
1, a bag storage chamber 12 is formed on the back side of the transparent portion 11, and an insect repellent bag 13 containing the insect repellent 10 is stored in the bag storage chamber 12 so as to be able to be taken in and out.

As shown in FIGS. 2 and 4, the transparent portion 11 is a transparent plastic molded product, and has a rectangular upper wall plate 15 in which a circular see-through portion 14 is formed in a bulging shape at the center. A bag storage room 12 is formed on the back side of the upper wall plate 15 on all four sides in the front, rear, left and right, and is surrounded by a peripheral side wall 16, and a circular flange plate 18 is integrally formed to project outward from a lower end of the peripheral side wall 16, A plurality of notch recesses 19 are formed in the outer peripheral edge of the flange plate 18 at equal intervals in the circumferential direction.

The transparent portion 11 is formed with a circular opening 20 of the upper lid 4.
Is integrally connected to the back side of the top plate 4a having
At this time, the circular see-through portion 14 is fitted into the opening 20 of the upper lid from the back side, and the overlapped surface between the upper wall plate 15 and the back surface of the top plate portion 4a is welded.

Thus, the lower surface of the opening of the bag storage chamber 12 formed in the transparent section 11 is closed and opened by the floor wall plate 21. As shown in FIGS. 2 and 3, the floor wall plate 21 is a plastic molded product formed in a bowl shape so as to be fitted to the circular flange plate 18. A plurality of engaging pieces 22 having a shape corresponding to the concave portion 19 are formed at equal intervals in the circumferential direction, and circular and arc-shaped ventilation holes 23 for communicating the bag storage chamber 12 with the inside of the rice bin main body 1.
Having.

The floor wall plate 21 is bayonet-coupled to the flange plate 18. That is, with respect to the flange plate 18, the floor wall plate 21 inserts the engaging pieces 22 into the cutout recesses 19 from below the flange plate 18 and then moves the entire floor wall plate 21 clockwise or counterclockwise (FIG. 3).
When rotated horizontally in the counterclockwise direction, the engagement piece 22 comes into contact with the outer surface of the peripheral side wall 16 and simultaneously engages with an intermediate portion between the notch recesses 19 on the upper surface side of the flange plate 18. By the combination, a state where the floor wall plate 21 does not come off from the flange plate 18 is obtained, and the closed state of the bag storage chamber 12 is maintained. From this closed state, the entire floor wall plate 21 is horizontally rotated in the opposite direction to the above, and the engagement piece 22 is pulled out from the notch recess 19 downward at a rotation angle position where the engagement piece 22 exactly matches the notch recess 19. Thus, the floor wall plate 21 can be removed from the flange plate 18.

The detaching operation of the floor wall plate 21 is performed when the insect repellent bag 13 is put in and taken out of the bag storage room 12. At this time, the upper cover 4 is removed from the rice inlet 3 and the upper cover 4 is removed.
Can be easily performed in the state of turning over.

As the insect repellent 10, an insect repellent which is volatile and discolors by volatilization and whose decrease in insect repellent effect can be judged by the discoloration is used. For example, a state in which allyl isothiocyanate, a pungent component of mustard and wasabi, and a hydrophobic substance such as wax having food safety (embedding agent) are kneaded in the pores of a granular carrier made of porous cellulose. Embedded in, in addition to
Among the insect repellents described in JP-A No. 0-17846, those having food safety are used.

The insect repellent bag 13 is a transparent or translucent material that can be viewed through the inside and is capable of volatilizing the drug, for example, Japanese paper,
A non-woven fabric, a woven fabric (such as gauze, gauze, or organdy), kraft paper, or the like is used to form a flat bag and contains the insect repellent 10.

In the rice bin having the above structure, the insect repellent 10 in the insect repellent bag 13 stored in the bag storage chamber 12 on the back side of the upper lid 4 is not buried in the rice, and the vent holes 23 are formed. The gas is volatilized evenly from above in the rice storage chamber 2 over the whole rice, thereby effectively exhibiting the insect repellent function. In addition, the insect repellent 10 in the insect repellent bag 13 can be stored and arranged in the bag storage chamber 12 so as not to be in close contact with the see-through portion 14 or the back surface of the upper wall plate 15 by its own weight. Can always be satisfactorily volatilized without being hindered. In addition, as shown in FIG.
It is possible to provide ribs or protrusions 24 on the back side of
This is preferable in that the insect repellent bag 13 can be more reliably separated from the rear surfaces of the see-through portion 14 and the upper wall plate 15 without making the bag close to the rear surfaces of the see-through portion 14 or the upper wall plate 15 and good volatilization can be guaranteed.

The insect repellent 10 changes color over time.
This color change can be visually recognized from the see-through portion 14 of the transparent portion 11 of the upper lid 4, and the functional deterioration of the insect repellent 10 due to the color change can be easily confirmed from the outside. Since the top cover 4 is always opened and closed when replenishing rice, it is possible to confirm the state of deterioration of the insect repellent function due to the discoloration of the insect repellent 10 from the see-through portion 14 each time. Replacement can be promoted at an appropriate time without delay.

The insect repellent 10 having a reduced insect repellent function comprises
Can be easily replaced with a new insect repellent 10 by opening the floor wall board 21 from the rice bottle main body 1.
When the rice worm becomes an adult, the adult can escape to the outside through a relief hole 9 provided at an upper corner of the front wall 6 of the rice bin main body 1 as shown in FIG. This makes it difficult for adult carcasses to remain in the rice. In addition, escape holes 9 are provided in corners where adults can easily settle, thereby facilitating escape of adults.

In the above embodiment, the bayonet connection is employed as a means for attaching and detaching the floor wall plate 21 to and from the bag storage room 12. The board 21 may be slidably mounted in the front-rear or left-right horizontal direction so that the bag storage chamber 12 can be opened and closed by sliding the floor wall board 21.

Further, in the above embodiment, the bag storage chamber 12 is formed also as the transparent section 11, and the bag storage chamber 12 can be opened and closed by the floor wall plate 21 separate from the upper lid 4. Not limited to As shown in FIG. 5, the top plate 4a of the upper lid 4
A bag storage chamber 12 is formed so that a part of the surface of the bag storage chamber 12 is depressed, and a ventilation hole 23 is provided at the bottom of the bag storage chamber 12. Alternatively, the cap 25 may be detachably fitted into the bag storage chamber 12 from above. Cap 2
