Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice bowl having an entrance on a top surface of a container body that can be opened and closed by a lid. The rice bin is used by being housed in, for example, a storage portion on the side of the kitchen table of the system kitchen.

[0002]

2. Description of the Related Art There are various types of rice jars which are constructed so that the entrance and exit of the rice can be opened and closed with a lid and are known in the market. This type of rice box is composed of a rectangular box-shaped container body, a lid receiver attached to the opening edge of the upper surface of the container body, and a lid for opening and closing an entrance provided in the lid receiver. The lid can be swung up and down to open and close the entrance and exit, and can be slid forward and backward to open and close the entrance and exit. Most of the rice bin components are made of plastic moldings, but some rice bins are made entirely of wood.

[0003]

In the case of rice bins, which are often used continuously for a long period of time, it is necessary to surely prevent pests and the like from entering through the openings and the joints of the components. In many cases, a rubber packing seals a gap between the doorway and the lid and a joint gap between the container body and the lid receiver. In particular, in the case of a plastic container body, the peripheral side wall is liable to be bent and deformed due to the lateral pressure and weight of rice, so that a seal for preventing a gap cannot often be omitted. As described above, it is easy to seal the gap using the packing, but it is inevitable that the number of parts of the rice box increases and the overall cost increases.

In many cases, the sliding lid is guided and supported so as to be able to slide back and forth along the inner surface of the upper wall of the lid receiver. Therefore, it is necessary to separately provide a guide structure for the lid on the inner surface of the lid receiver, which complicates the structure of the lid receiver,
This also contributed to the cost increase. In particular, when the lid receiver is formed of a plastic molded product, it is difficult to integrally mold the guide structure, so that it is inevitable that the number of component parts is increased accordingly.

An object of the present invention is to provide a rice box that can reliably prevent the invasion of harmful insects, etc., while minimizing the number of constituent parts and reducing the manufacturing cost of the rice box. Another object of the present invention is to provide a rice plate made of a metal plate which has a high degree of tightness and has no room for pests to enter even though all the components are made of a metal plate.

[0006]

In the rice jar of the present invention, a container body 1 having an open upper surface, a lid receiver 2 fitted and mounted on the container body 1, and a doorway 3 opened in the lid receiver 2 are slid and opened. And a lid 4. The lid 4 is provided with a pair of side walls 14 and 14 slidably guided by a guide body 8 provided on the outer surface of the opposite side wall of the container body 1, and a lid main wall 13 connecting the side walls 14 and 14. Main lid wall 1 when the lid is closed
3 is formed with a recessed seal recess 17 that is recessed into the inlet / outlet 3 and closely engages with the peripheral edge of the opening of the inlet / outlet 3.

The seal recess 17 is provided with a stopper 19 which contacts the open end and the closed end of the entrance / exit 3 and defines the open limit and the close limit of the lid 4. This stopper 1
Reference numeral 9 also serves as an operation unit 20 for opening and closing the lid 4.

Outer rib-shaped guide bodies 8 are provided on both side walls of the container body 1, and correspondingly, both side walls 14.1 of the lid 4 are provided.
A slide groove 15 guided by the guide body 8 is formed on the inner surface near the lower end of 4. A guide slope 18 for facilitating the ride of the seal recess 17 on the lid 2 is formed on the peripheral side surface of the seal recess 17 on the opening start side in an upwardly inclined shape.

The container body 1, the lid receiver 2 and the lid 4 are each made of a stainless plate material. Container body 1
Is a body 5 and a bottom plate 6 that is folded and joined to the lower end of the body 5.
And form a box shape. The lid receiver 2 includes a four-peripheral wall 10 that is externally fitted and engaged with the opening edge of the body portion 5, and a main surface wall 11 in which the doorway 3 is opened. By using the guide body 8 for the lid 4, this can also serve as the regulating rib 7 that defines the engagement limit of the lid receiver 2.

[0010]

In the same manner as the can lid is engaged with the can body, the lid receiver 2 is engaged and attached to the container body 1 to prevent a gap from being formed between the container body 1 and the lid receiver 2, Further, by closely engaging the seal recess 17 formed in the lid main wall 13 of the lid 4 with the opening peripheral edge of the entrance / exit 3, the entrance / exit 3 is closed in the lid closed state.
A gap is prevented from being formed between the lid 4 and the lid 4. Therefore, it is possible to secure a necessary and sufficient degree of sealing of the rice bin without using a part dedicated to the seal such as packing. Since the container body 1, the lid receiver 2, and the lid 4 constitute a rice bin, the number of constituent parts of the rice bin can be minimized and the manufacturing cost thereof can be reduced.

The seal recess 17 is provided with a stopper 19 for defining the opening / closing limit of the lid 4 and the stopper 19 is used as the operating portion 20. According to the rice box, the opening / closing operation of the lid 4 is facilitated while preventing an increase in the number of parts. And the usability of rice can be improved by that amount. Since the open position and the closed position of the lid 4 can be clearly defined by the stopper 19 at appropriate positions, it is often left unattended in a state where a gap is created between the lid 4 and the doorway 3. It can be prevented.

The lid 4 is slid to open and close the entrance / exit 3 while covering the upper surface of the lid receiver 2. In the closed state, the seal recess 17 is engaged with the inside of the entrance / exit 3 by being depressed. It prevents the formation of a gap between and. Therefore, when the lid 4 is opened from the closed position, the seal recess 17 rides on the main surface wall 11 of the lid receiver 2. In order to facilitate this climbing and facilitate the opening operation of the lid 4, an upwardly inclined guide slope 18 is provided on the peripheral side surface of the seal recess 17 on the opening start end side.

The container body 1, the lid receiver 2 and the lid 4 are each formed of a stainless plate material, and the guide body 8 for the lid 4 is attached to the lid receiver 2.
When used as the regulating rib 7 for defining the engagement limit of
Compared to the case where the restriction rib 7 is separately provided, the number of processing steps of the container body 1 is reduced, and the rice box can be formed at a lower cost.
When the container body 1 is formed into a rectangular box shape with the body portion 5 and the bottom plate 6 that is folded and joined to the body portion 5, the container body 1 is manufactured as compared with the case where the container body 1 is formed by drawing. In this case, the initial investment amount such as a mold can be reduced, and even when preparing several kinds of rice cavities having different capacities, the rice cavities can be formed at low cost.

[0014]

1 to 6 show an embodiment of a rice bin according to the present invention. In FIG. 2 and FIG. 3, the rice box is a rectangular box-shaped container body 1 with an open top surface, a lid receiver 2 fitted and attached to the opening edge of the container body 1, and a door 3 provided on the lid receiver 2 for sliding opening and closing. It is configured with the lid 4 that operates. Container body 1, lid receiver 2
The lid 4 and the lid 4 are each formed of a stainless plate material.

The container body 1 is composed of a body portion 5 and a bottom plate 6 folded and joined to the lower end of the body portion 5. A guide body 8 which also functions as a regulating rib 7 for the lid receiver 2 is provided in the shape of an outer protruding rib near the upper end of the four sides of the body portion 5. In other words, among the regulating ribs 7 that circulate on the four circumferential side surfaces of the body 5, the ribs provided on the left and right side walls (long side portions) of the body 5 are used as the guide body 8. As described above, the container body 1 configured by the body portion 5 and the bottom plate 6 has a plurality of types of container bodies 1 having different capacities as compared with the case where the entire container body 1 is formed of a plastic molded product or a drawn product. When provided, the initial investment amount for the molding die can be reduced, which helps reduce the manufacturing cost of the container body 1 accordingly.

The lid receiver 2 has a four-sided wall 10 which is externally fitted and engaged with the opening edge of the body portion 5, and a main surface wall 1 on the upper surface side through which the doorway 3 is provided.
1 and 1 are integrally formed by drawing. Doorway 3
The opening edge of and the opening edge of the four peripheral wall 10 are each subjected to hemming processing to prevent injury, and are folded inward. Similarly, the opening edge of the body portion 5 is also folded back. The entrance / exit 3 is opened in the laterally long direction in a state of being adjacent to one short side portion of the principal surface wall 11. In the state where the lid receiver 2 is attached to the container body 1, as shown in FIG.
The outer peripheral surface of the opening is fitted to prevent the formation of a gap between the two and the two. In addition, the regulation rib 7 provided on the body portion 5
The bottom edge of the four peripheral wall 10 is received to prevent the lid receiver 2 from being further engaged with the body portion 5.

The lid 4 is formed in a U-shaped cross-section by a lid main wall 13 which is slightly larger than the entrance 3 and a pair of left and right side walls 14 which are continuously bent on both left and right sides of the lid main wall 13. It is assembled in the container body 1 in a state of covering the lid receiver 2 and is slidably guided forward and backward. Specifically, by forming an outer recessed slide groove 15 on the inner surfaces of the pair of side walls 14 near the lower ends, and engaging and supporting the groove 15 with an outer protruding rib-shaped guide body 8 provided in the body portion 5, The entire lid 4 is supported along the main surface wall 11 of the lid receiver 2 so as to be slidable and openable. The front and rear edges of the lid 4 and the lower edge of the side wall 14 are each folded inward to prevent injury. Further, the front and rear edges of the slide groove 15 are bent outwardly to form an escape portion 16 as shown in FIG. The escape portion 16 prevents the front and rear ends of the slide groove 15 from being caught by the guide body 8 when the lid 4 is opened and closed.

When the lid 4 is closed, in order to prevent a gap from being formed between the doorway 3 and the lid 4, the plate surface of the lid main wall 13 is dropped into the doorway 3 to form an opening edge of the doorway 3. The recessed seal recess 17 is formed so as to be in close engagement. The recess depth of the seal recess 17 is about 2 mm, and the peripheral side surface thereof is formed in a downwardly tapered shape so that the peripheral side surface can be securely and closely engaged with the inlet / outlet 3. When the lid 4 is opened from the closed position, the seal recess 17 rides on the main surface wall 11 of the lid receiver 2. In order to facilitate this riding, a guide slope 18 is formed on the peripheral side surface on the opening start end side of the peripheral side surfaces as shown in FIG. The guide slope 18 is formed as an upward slope from the bottom wall of the seal recess 17 toward the main lid wall 13, and the slope angle is set to about 45 degrees.

As described above, the lid 4 can freely slide within the front-back range of the guide body 8 along the outer surfaces of the lid receiver 2 and the body portion 5. Therefore, even if the lid 4 is intended to be closed, there is a possibility that the seal concave portion 17 may not fall into the entrance / exit 3, or may climb onto the main surface wall 11 on the front side of the entrance / exit 3 to cause a gap. In order to define the opening / closing position of the lid 4 when the lid is opened / closed, a stopper 19 is provided at the left / right center of the front peripheral side surface of the seal recess 17. The stopper 19 is formed by further recessing downward from the seal recess 17 and also serves as an operating portion 20 for opening and closing the lid 4. Specifically, the front-rear width and the left-right width of the stopper 19 are set so that several fingertips can sufficiently enter.

When the lid 4 is closed, the front wall of the stopper 19 comes into contact with the opening edge on the front side of the doorway 3 to prevent the lid 4 from sliding further forward (solid line state in FIG. 1). . On the contrary, when the lid 4 is opened, the rear wall of the stopper 19 is received by the opening edge on the rear side of the doorway 3 as shown by the imaginary line in FIG. 1, and the lid 4 cannot slide backward any further. . By the way, when the lid 4 is opened, as shown in FIG.
As shown in, the bottom wall of the seal recess 17 rides on the main surface wall 11 of the lid receiver 2. Therefore, the entire lid 4 is pushed slightly higher than when the lid is closed, and the lower end of the slide groove 15 is received by the guide body 8. Furthermore, the main lid wall 1
The whole 3 is bent and deformed in an upward projecting manner to absorb the dimensional difference caused by the riding of the lid 4. In this state, the slide groove 15
Since an appropriate frictional resistance is generated between the guide body 8 and the guide body 8, even if the lid 4 is opened by an excessive force, the stopper 19 violently collides with the rear opening edge of the doorway 3 and is deformed. Can be well prevented.

In addition to the above-described embodiment, the lid receiver 2 can be fitted and mounted in the container main body 1 as shown in FIG. In this case, the upper end of the body portion 5 is curled inward to form the regulation rib 7. That is, the regulation rib 7 and the guide body 8 can be provided separately. A step portion 23 that is received by the regulating rib 7 is provided on the four peripheral walls 10 of the lid receiver 2.

As shown in FIG. 7, the guide body 8 may be formed as a groove recessed inward of the container body 1. In this case, the guide body 8 is engaged with the pair of side walls 14 and 14 of the lid 4. An inwardly projecting slide rib 15a is provided.

Most of the rice bins are used by accommodating them in a storage cabinet of a kitchen or a storage room of a kitchen table, but they may also be stored in a drawer of a kitchen table or a storage cabinet and used. In that case, as shown in FIG. 8, the outer dimension of the body portion 5 is set to be slightly smaller than the inner surface dimension of the drawer 25, and the container body 1 is set to the left and right side plates 26 of the drawer 25 and the rear end plate 2.
7, the step portion 28 formed in the body 5 in a circular shape is received and supported by the upper end surfaces of the left and right side plates 26, 26 and the rear end plate 27 so that the entire rice bin fits in the drawer 25. To do so. In this case, the drawer 25 omits the bottom plate to save space. Of course, the rice bin may be stored as it is in an ordinary drawer having a bottom plate. In FIG. 8, reference numeral 29 is an end plate of the drawer, 3
0 is the handle.

Further, the stopper 19 is formed as a separate part from the lid 4, and for example, in a state of being press-fitted and fixed in the seal recess 17, a part of the stopper 19 is projected to the upper surface side of the seal recess 17 so that the operation portion 20 is formed. Can also serve as
The container body 1, the lid receiver 2, and the lid 4 can be formed of a coated steel plate, a pre-coated steel plate other than a stainless steel plate material, or a non-ferrous metal plate. When a large amount of the same type of rice grains is supplied at the same time, the container body 1, the lid receiver 2 and the lid 4 may be formed of plastic molded products. For the same reason, the container body 1 can be formed by a single pressed part that has been drawn.

[0025]

The rice jar of the present invention comprises a container body 1, a lid receiver 2, and a lid 4 for slidingly opening and closing the entrance / exit 3.
It is not necessary to use parts for exclusive use of seals such as rubber packing, and it is possible to prevent the formation of gaps between the constituent members, through which harmful insects can enter. Specifically, the lid receiver 2 was fitted and mounted on the container body 1 to prevent a gap from being formed between the joint portions of the both 1 and 2. Further, the seal recess 17 is formed in the lid 4 in advance, and when the lid 4 is closed, the seal recess 17 fits into the inlet / outlet 3, so that a gap is generated between the inlet / outlet 3 and the lid 4. Prevented. Therefore, according to the present invention, it is possible to minimize the number of constituent parts and reduce the manufacturing cost of the rice box, although the rice box can satisfy the insect repellent function.

Further, the container body 1, the lid receiver 2, and the lid receiver 2
Since the joint structure of the doorway 3 and the lid 4 is used to prevent a gap where pests can enter between the joints, even if all the constituent parts are formed of metal plates, It is possible to construct a rice box with a high degree of tightness that does not have room for entering, making it possible to obtain a rice box that is cheaper than the conventional plastic rice box, and when preparing multiple types of rice boxes with different capacities, make an initial investment such as a mold. Because the cost required is small,
The cost of each rice can be reduced.
