DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooker in which a cutter is provided in a container, and the object to be cooked, such as food, stored in the container is cut and agitated by the cutter.

[0002]

2. Description of the Related Art This type of cooker is called a food processor or the like, in which a cutter is disposed in a container, and the cutter is rotated by a driving means such as an electric motor so as to be accommodated in the container by the cutter. The cooked material is cut or stirred to cook.

[0003] A conventional cooker has a configuration as shown in FIG. 11. To explain this, the cooker is composed of a main body 100, a container 101, a lid 118, and a rotating body 115.

The main body 100 has a motor 103, a normally open switch 104 for connecting the motor 103 to a power source (not shown), and a switch 1
Actuator 10 with Actuator Rod 106 for Opening and Closing Opening 04
5 are provided. Drive shaft 107 of the electric motor 103
Is mounted with a concave coupling 108 having an uneven engaging piece 108a formed on the inner peripheral surface.

[0005] The container 101 is formed in a bottomed cylindrical shape having an open top, and a support shaft 11 is provided on the bottom 109 thereof.
0 is fixedly provided.

The rotating body 115 is accommodated in the container 101. The rotating body 115 has a cutter 111 and a bearing 112 at its lower end rotatably fitted to the support shaft 110. At the upper end, a convex coupling 114 having a concave and convex engaging piece 113 that engages with the engaging piece of the concave coupling 108 is provided.

A plurality of vertical support ribs 116 are provided on the inner peripheral wall of the container 101 so as to be spaced apart in the circumferential direction.
The lid 118 is detachably provided at the upper end of the support rib 116 so that the food in the container 101 does not jump out. The cover 118 has a through hole 117 at the center thereof, through which the convex coupling 114 passes.

In such a cooker, a rotating body 115 is accommodated in a container 101, a lid 118 is closed in the container 101, and the convex coupling is formed through a through hole 117 formed in the center of the lid 118. 114 is penetrated. And container 10
1 and the concave coupling 108 is engaged with the convex coupling 114. In this state, the main body 1 is positioned at one end of the opening, that is, on the right side in the drawing.
00, and the main body 100 is rotated counterclockwise in FIG.
1 is closed. Then, the operating portion 105 hits the edge 102 of the opening of the container 101 and is pushed upward, so that the switch 104 is closed, and the electric motor 103 is thereby driven. The rotation of the electric motor 103 drives the concave coupling 108 to rotate, and the rotating body 1 is rotated via the convex coupling 114 engaged with the concave coupling 108.
15 is rotated, and thus the cutter 111 is rotated.
Therefore, the object to be cooked in the container 101 is cut or stirred and cooked.

However, in the above-described conventional cooking device, when the main body 100 is lifted, the concave coupling 108 and the convex coupling 114 may not be disengaged and may be pulled up while being engaged. In such a case, since the rotating body 115 is pulled up integrally with the main body 100, the cutter 11
1 hits the lid 118, whereby the lid 118 is also removed from the container 101, and the lid 118 may be pulled up integrally.

In such a case, although the switch 104 has already been turned off, the motor 103 and the rotating body 115 may be rotating due to inertia.
When the rotating body 115 and the lid body 118 are integrally pulled out of the container 101 with the rotating cutter 115, the rotating cutter 111 is exposed outside the container 101, and the food adhered to the cutter 111 is scattered, There is a problem that stains the surroundings.

In order to prevent this, the cover 118 is attached to the container 1
It is conceivable to mount it on a rotary type with respect to 01. If the lid 118 is rotated and attached to the container 101, the lid will not easily come off even if the rotating body 115 hits the lid 118.

[0012]

However, the lid 11
In the case of a structure in which 8 is rotatably attached to and detached from the container 101,
When the container 101 is supported as if suspended by holding the main body 100 or the lid 118, if a rotational force is carelessly applied to the container 101, the container 101 comes off from the lid 118, and the container 101 falls. I have to worry.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an apparatus in which a lid is rotatably attached to and detached from a container. An object of the present invention is to provide a cooker in which the lid and the container are hardly detached.

[0014]

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to one embodiment shown in FIGS. FIG. 1 is a perspective view showing the whole of a food processor A as a cooker, and FIG.
Is an exploded perspective view thereof. In the appearance of the food processor A shown in FIG. 1, the container 1 and the main body 40 placed on the container 1 are visible.

The container 1 is formed of a transparent material such as glass or transparent resin so that the food to be stored in the container 1 can be seen from the outside. As shown in cross sections in FIGS. It is formed in a bottomed cylindrical shape having an opening 2 in the portion. A mounting hole 4 is formed at the center of the bottom wall 1a of the container 1, and a support shaft 5 corresponding to a bearing is mounted in the mounting hole 4. The support shaft 5 is fixed to the bottom wall 1a of the container 1 by means such as molding.
A flange portion 5a that contacts the bottom wall 3 is provided at the intermediate portion.

As shown in FIGS. 6 and 7, an annular insertion wall 7 having a diameter larger than the inner peripheral wall 6 of the container 1 is formed at the edge of the opening 2 of the container 1. The inner peripheral surface 7a of the wall 7 and the inner peripheral wall 6 of the container 1 are connected by an inclined step wall 7b which faces downward into the container 1.

At the edge of the opening 2, engagement grooves 3 are formed at positions facing the inner peripheral surface 7a of the insertion wall 7 at an angle of 180 degrees. As shown in FIG. 5 (A), these engaging grooves 3 are vertical grooves 3aa extending vertically and having upper ends opened at the opening edges of the openings 2.
A rotating body 20 which is connected to the lower end of the vertical groove 3aa and which will be described later.
Horizontal groove 3a extending in the circumferential direction along the direction opposite to the rotation direction
b, and the horizontal groove 3a
b, a locking portion 3b extending toward the bottom of the container 1 and a locking portion 3b further connecting to the depth of the horizontal groove 3ab.
And a bag portion 3c formed toward the opening direction of the bag.

In this embodiment, the vertical groove 3aa and the horizontal groove 3ab connected to the vertical groove 3aa are combined to form a groove extending obliquely. However, the vertical groove 3aa and the horizontal groove 3ab are clearly distinguished from each other. You may.

The bag portion 3c is not limited to be formed by a vertical groove as shown in FIG. 5A, but is shown in FIG. 5B if the outlet side is narrower. As described above, it may be formed by an inclined surface.

A spout 8 is formed on one side of the edge of the opening 2 of the container 1 so as to be located above the inclined step 7b. The container 1 is provided with a handle 9.

The opening 2 of the container 1 has a detachable lid 1
The cover is closed at 0. The lid 10 is made of, for example, a synthetic resin and has a dish shape with an open top. That is, the lid 10 has a through hole 1 at the center.
1, a substantially vertical annular wall 13 (also shown in FIGS. 5 and 6) extending upward from an outer peripheral portion of the bottom wall 12, and a horizontal direction above the annular wall 13. And an annular flange portion 14 extending to The annular flange portion 14 is adapted to be supported by the upper end surface of the rim of the opening 2 of the container 1, and thus has an outer diameter larger than the outer diameter of the insertion wall 7. At the opening edge of the through hole 11, an inclined annular projecting wall 10a projecting inward of the container 1 is formed, and a cylindrical wall 10b extending upward is formed so as to project.

On the outer surface of the vertical annular wall 13 of the lid 10, engagement projections 19 are formed. These engaging projections 19, 19 are inserted into the engaging grooves 3, 3 formed in the insertion wall 7 of the container 1 so as to be able to be inserted and removed, and guide the lid 10. That is, when the cover 10 is attached to the opening 2 of the container 1, the engaging protrusion 19 is inserted into the engaging groove 3, and the engaging protrusion 19 is guided by the engaging groove 3.
When the engagement projection 19 is inserted into the vertical groove 3aa of the engagement groove 3, the lid 10 is inserted into the insertion wall 7 of the container 1, and the engagement projection 19 is further connected to the horizontal groove 3ab connected to the lower end of the vertical groove 3aa.
The lid 10 is guided to rotate in the circumferential direction, that is, to rotate. Further, when the engaging projection 19 is inserted into the locking portion 3b located at the back of the horizontal groove 3ab, the lid 10 further enters the direction of the bottom of the container 1.

Therefore, when the cover 10 is attached to the opening 2 of the container 1, the cover 10 is inserted into the insertion wall 7, then turned in the horizontal direction, and is further pushed toward the inside of the insertion wall 7. To operate. As a result, the engaging projection 19 is moved to the vertical groove 3a.
From a, it passes through the horizontal groove 3ab and is inserted into the locking portion 3b at the back of the horizontal groove 3ab. When removing the lid 10 from the container 1, the reverse operation is performed.

However, the lid 10 is pulled up and the
Is released from the locking portion 3a, the engaging projection 19 is
, And may be locked to the bag portion 3c. If the engagement projection 19 does not climb over the projecting portion on the outlet side of the bag portion 3c, rotation cannot be performed, so that the lid 10 does not come off the container 1. In order to remove the lid 10 from the container 1, the lid 10 can be separated by passing the engaging projection 19 over the projecting portion on the outlet side of the bag portion 3c and leading it to the vertical groove 3aa.

As shown in FIGS. 6 and 7, a guide wall 15 extending horizontally is formed on the outer surface of the annular wall 13 of the lid 10, and the guide wall 15 is an insertion wall of the container 1. 7 is slidable along the inner peripheral surface 7a. That is, the outer diameter D ₁₅ of the guide wall 15 is the insertion wall 7
The guide wall 15 is formed smaller than the inner diameter D ₇ of the inner peripheral surface 7a of the insertion wall 7 (D ₁₅ <D ₇ ).
a with a slight gap. Therefore, the guide wall 15 is slidable along the inner peripheral surface 7a of the insertion wall 7.

The guide wall 15 may be formed in a flange shape continuously in the circumferential direction, or may be formed in three or more places along the circumferential direction. However, if the guide wall 15 is formed in a flange shape that is continuous in the circumferential direction, if a seal body such as an O-ring 17 described later is damaged and the sealing function is impaired, the flange-shaped guide wall may be used. The use of 15 makes it possible to prevent the cooking ingredients and liquid in the container 1 from leaking to the outside.

Further, an annular mounting groove 16 is formed below the guide wall 15 on the outer surface of the annular wall 13 of the lid 10. A sealing member made of an elastic member such as rubber, for example, an O-ring 17 is attached to the mounting groove 16. The O-ring 17 is formed so as to have a diameter larger than the outer diameter of the annular wall 13 when fitted into the mounting groove 16, that is, so that the outer periphery projects outward from the annular wall 13. In this case, the outer periphery of the O-ring 17 is
3 is 4 times the cross-sectional diameter d of the O-ring 17.
It is formed to be 0 to 60%, preferably approximately 50%. When the O-ring 17 is fitted in the mounting groove 16, the outer diameter D ₁₇ of the O-ring 17 is equal to that of the guide wall 1.
5 smaller than the outer diameter _{D 15 (D 17 <D 15} ) are formed. However, the diameter D ₁₇ of the outer circumference of the O-ring 17 is greater than the inner diameter D ₆ of the inner circumferential wall 6 of the container 1 (D _17> D ₆₎ are formed. The outer diameter D ₁₇ of the O-ring 17 fitted in the mounting groove 16 is determined by the insertion wall 7 formed in the opening 2 of the container 1.
It is formed smaller than the inner diameter D ₇ of (D ₁₇ <D ₇₎
Things.

Therefore, when closing the opening 2 of the container 1 with the lid 10, the guide wall 15 of the lid 10 slides on the inner peripheral surface 7 a of the insertion wall 7 as shown in FIG. At this time, the outer periphery of the O-ring 17 is prevented from contacting the inner peripheral surface 7a of the insertion wall 7 at this time. Since the O-ring 17 is made of an elastic member such as rubber, when the cover 10 is inserted into or taken out of the opening 2 of the container 1, the insertion wall 7 of the container 1 is used.
If the O-ring 1 slides on the O-ring 1
7 is prevented from contacting the inner peripheral surface 7a of the insertion wall 7, the frictional resistance of the O-ring 17 does not act, and the lid 10
The work of attaching and detaching is extremely easy.

However, as shown in FIG. 7, when the annular flange portion 14 of the lid 10 is in contact with the upper end surface of the rim of the opening 2 of the container 1, the O-ring 17 is in the closed state. 1
The O-ring 17 elastically deforms the O-ring 17 so that the lid 10 is elastically pressed to the opening 2 of the container 1.

That is, the O-ring 17 is pressed into contact with the stepped wall 7b by inserting the lid 10 into the opening 2 of the container 1 at a predetermined depth and press-fitting when the predetermined depth is reached. The lid 10 mechanically engages the container 1 due to frictional resistance. For this reason, the sealing property between the container 1 and the lid 10 is maintained, and it is possible to reliably prevent the cooking material and the liquid in the container 1 from leaking out during cooking.

In this case, when the engaging projections 19, 19 formed on the lid 10 are located in the vertical groove 3aa and the horizontal groove 3ab in the engaging grooves 3, 3 on the container 1, the O-ring 17 is not stepped. The O-ring 17 does not reach the inner wall 7b, that is, the O-ring 17 does not come into contact with the inner peripheral surface 7a of the insertion wall 7 and is in a loose fit state. 3b, 3
b, the O-ring 17 is pressed against the step wall 7b. Therefore, the lid 10
Does not reach the normal lid closing position, and during the turning operation, the O-ring 17 is in a loosely fitted state with the inner peripheral surface 7a of the insertion wall 7, so that the frictional resistance of the O-ring 17 does not occur.

At this time, since the other operating plate 79 of the operating body 75 is in contact with the upper end of the push-up body 90, when the operating body 75 is lowered, the operating body 75 is counterclockwise against the urging force of the torsion coil spring 87. Therefore, one operating plate 78 of the operating body 75 pushes down the operating element 71 of the switch 70. For this reason, the switch 7
The zero contact is closed.

On the other hand, as shown in FIG.
When the annular projecting wall 18 of the lid 10 is separated from the second fitting groove 43, that is, when the main body 40 is lifted away from the lid 10, the push-up body 90 facing the fitting groove 43. Is pushed away by the other operating plate 79 of the operating body 75,
It projects from the fitting hole 44 into the fitting groove 43. In this case, since the operating body 75 is rotated clockwise by the urging force of the torsion coil spring 87, the operating body 7 is rotated as described above.
The other operation plate 79 of 5 pushes down the lifting body 90. Accordingly, one operation plate 78 of the operation body 75 is separated from the operation element 71 of the switch 70. Therefore, in this state, the operating body 80 provided on the ridge 41a of the upper case 41
Is pressed down, and the operation button 81, the button axis 81a, the button axis 81a,
Even if the operating frame 83 is pushed down via the operating rod 82, the one operating plate 78 of the operating body 75 does not reach the operator 71 of the switch 70, so that the operator 71 cannot be pushed down. Therefore, the contact of the switch 70 is not closed.

A power supply cord 95 is led out of the connection between the upper case 41 and the lower case 42. The protector portion 96 of the power cord 95 has a mounting groove 96a formed in the protector portion 96 and the upper case 41 and the lower case 4
It is fitted and fixed between the two opening edges. An inner end of the power cord 95 is connected to the switch 70, and a plug 97 to be inserted into a power supply socket is attached to an outer end.

Next, the cooking device A configured as described above
The operation of will be described.

First, the rotating body 20 is fitted into the container 1 by fitting the bearing 34 to the shaft 5 provided on the container bottom 1a.
Next, a subject to be cooked for desired cooking is put. Then, the convex coupling 23 of the rotating body 20 penetrates the through hole 11 of the lid 10, and the opening 2 of the container 1 is closed with the lid 10.

The lid is closed as follows. That is, the cover 10 is opposed to the insertion wall 7 of the container 1, and the engagement protrusions 19 are fitted into the engagement grooves 3. When the engaging projection 19 reaches the lower end of the vertical groove 3aa, the cover 10 is turned in the horizontal direction. Then, the engaging projection 19 is guided by the horizontal groove 3ab.
When the engaging projection 19 reaches the inner part of the horizontal groove 3ab,
Push in the lid 10.

In such an operation, when the engaging projections 19 of the lid 10 are located in the vertical groove 3aa and the horizontal groove 3ab of the engaging grooves 3, 3, the O-ring 1
7 is in a loosely fitted state without contacting the inner peripheral surface 7 a of the insertion wall 7. Therefore, since the O-ring 17 does not come into contact with the inner peripheral surface 7a of the insertion wall 7 at the initial stage of the insertion of the lid 10 and during the turning operation, frictional resistance of the O-ring 17 does not occur.
Good insertion and removal workability. When the engagement projections 19 are dropped into the locking portions 3b, the O-ring 17 is pressed against the step wall 7b and is elastically deformed, so that the sealing between the lid 10 and the container 1 is performed. Will be maintained.

When the lid 10 is closed in the container 1 in this manner, the main body 40 is placed on the lid 10. At this time, the annular projecting wall 18 provided on the lid 10 is fitted into the fitting groove 43 formed in the lower case 42 of the main body 40. In this state, as shown in FIG. 9, the push-up body 90 is pushed upward by the annular projecting wall 18 of the lid 10, so that the operating body 8
By pressing down 0, the switch 70 can be closed. The concave coupling 61 of the main body 40 and the convex coupling 23 of the rotating body 20 are engaged with each other, and the annular flange 25 is provided at the opening edge of the through hole 11 of the lid 10.
0a is located at a position close to the lower edge.

When the operation button 81 is depressed downward, the operation frame 83 is moved downward, so that the operation body 75 is rotated clockwise, the operator 71 of the switch 70 is depressed, and the contact of the switch 70 is turned on. Is closed. Therefore, the electric motor 46 is energized, and the electric motor 46 is driven. The drive of the motor 46 rotates the motor shaft 46d, and the bevel gear 59 is rotated via the small-diameter pulley 48, the belt 52, the large-diameter pulley 51, and the bevel gear 53. Therefore, the rotating body 20 is rotated via the concave coupling 61 and the convex coupling 23, the cutters 35a and 35b are rotated within the container 1, and the object to be cooked is cut, crushed, and stirred.

After the cooking is completed, the main body 40 is separated from the container 1 by removing the main body 40 from the lid 10, and then the lid 1 is removed.
0 is removed from the container 1, and the food in the container 1 is transferred to another container or the like as necessary. Then, the cooking operation is completed by washing the container 1, the rotating body 18 and the lid 10.

In a state where the main body 40 is detached from the lid 10, as shown in FIG.
8 is disengaged from the fitting groove 43, so that the push-up body 90
Protrudes and the operating body 75 is moved even when the operating body 80 is moved downward.
Does not depress the operator 71 of the switch 70.
Therefore, even if the operation button 81 is operated by mistake, the switch 70 is not closed, and the electric motor 46 is not driven. Therefore, the concave coupling 61 exposed on the lower surface of the main body 40 does not rotate, which is safe.

In the case of the above embodiment, when the lid 10 is attached to and detached from the container 1, the lid 10 is rotated, but the outer diameter D ₁₇ of the O-ring 17 fitted in the mounting groove 16 is It is formed smaller than the inner diameter D ₇ of the inner peripheral wall 7a of the insertion wall 7 formed in the opening 2 of the container 1 (D
₁₇ <D ₇ ) Therefore, when the lid 10 is inserted into the insertion wall 7, the O-ring 17 does not contact the inner peripheral wall 7 a of the insertion wall 7,
Therefore, the contact resistance is small, and the lid 10 can be easily rotated. Therefore, operability is good.

The outer diameter D ₁₇ of the O-ring 17 is larger than the inner diameter D ₆ of the inner wall 6 of the container 1 (D ₁₇ > D ₆ ).
O-ring 17 is formed at the lower end of insertion wall 7,
That is, when reaching the inclined step wall 7b, the step wall 7b
And elastically deform. Due to this elastic deformation, the O-ring 17 frictionally engages with the container 1, so that the lid 10 is mechanically engaged with the opening 2 of the container 1.

In this case, the O-ring 17 has an amount s by which the outer periphery of the O-ring 17 protrudes from the annular wall 13 of the lid 10.
Is formed so as to be 40 to 60%, preferably approximately 50% of the cross-sectional diameter d of the O-ring 17, and the O-ring 17 undergoes a sufficiently large elastic deformation.

The accuracy of the stepped wall 7b on the container 1 side may be low due to molding errors and molding variations.
Is formed so as to be 40 to 60%, preferably approximately 50% of the cross-sectional diameter d, so that even if the stepped wall 7b is inaccurate due to a large amount of deformation, the stepped wall 7b is surely adhered. become. Therefore, a high sealing property is maintained, and it is possible to reliably prevent the cooking material or the pressure in the container 1 from leaking out during cooking.

[0072] Then, on the outer surface of the annular wall 13 of the lid 10, less than the inner diameter D ₇ of the outer diameter D ₁₅ is the inner peripheral wall 7a of the insertion wall ₇ (D ₁₅ <D 7) formed guide wall 15 The guide wall 15 is guided by the inner peripheral wall 7a of the insertion wall 7 when the cover 10 is inserted into the insertion wall 7 because it is provided.
Therefore, even if the O-ring 17 does not contact the inner peripheral wall 7a of the insertion wall 7, the lid 10 is guided by the guide action of the guide wall 15, and is inserted eccentrically, or the lid 10 tilts during insertion. Is prevented. For this reason, the O-ring 17 abuts the step wall 7b almost uniformly over the entire circumference, and is elastically deformed almost uniformly, thereby exhibiting a good sealing action.

During the cooking as described above, the cooking ingredients are vigorously stirred in the container 1.
The annular flange 2 having a diameter larger than the through hole 11 of the lid 10
Since the annular flange 25 is provided near the through-hole 11, the annular flange 25 reliably prevents the cooking material from jumping out of the through-hole 11 to the outside. Therefore, the outer surface of the lid 10 or the concave coupling 61
The cooking material does not adhere to the convex coupling 23 and the lower surface of the main body 1 or the like. Therefore, contamination of the main body 1 caused by the adhesion of the cooking material, that is, the object to be cooked or the like is prevented, and there is no need to clean the main body 1, and there is no adverse effect on the electric motor 46 that may occur due to the contamination. Can be prevented.

The annular collar 2 provided on the rotating body 20
Numeral 5 has a function as a knob for attaching and detaching the rotating body 20 to and from the container 1. In addition, since the annular flange 25 is formed in a circular plate shape, it is easy to grasp, and operability of attaching and detaching is provided. Is good.

When the main body 40 is detached from the container 1, as shown in FIG. 10, since the main body 40 is separated from the lid 10, the push-up body 90 projects downward, and the operating body 75 is turned on by the switch 7.
0, the switch 70 is turned off, but the motor 46 and the rotating body 22 may continue to rotate due to inertia. In this state, when the main body 40 is removed from the container 1, the convex coupling 23 and the concave coupling The rotating body 22 being rotated tends to be pulled out together with the main body 40 because the 61 is engaged. However, since the annular flange 25 of the rotating body 22 comes into contact with the annular projecting wall 10 a formed in the through hole 11 of the lid 10, the convex coupling 23 and the concave coupling 61 are disengaged. It does not jump out of the container 1.

The annular flange 25 of the rotating body 22 is
, The lid 10 is lifted and tends to be separated from the container 1. However, the engaging projections 19 formed on the lid 10 are engaged with the engaging portions 3b of the engaging grooves 3, so that However, even if the engaging projection 19 is disengaged from the engaging portion 3b, the engaging projection 19 enters the bag portion 3c and engages with the bag portion 3c to move along the horizontal groove 3ab. Is prevented. Therefore, since the lid 10 is not rotated, it does not come off the container 1. For this reason, the lid 10 does not come off the container 1 carelessly.
Remains reliably in the container 1 closed by the lid 10.

For example, when the container 1 is covered with the lid 10 and the cylindrical wall 10b of the lid 10 is lifted up, the O-ring 17 is disengaged from the stepped wall 7b and the engagement projection 1 is removed.
9 may come off from the locking portion 3a. At this time, container 1
When any rotational force is applied to the container 1, the container 1 and the lid 10 rotate relatively, the container 1 comes off, and the container 1 may fall. However, when the bag portion 3c is formed as in the above-described embodiment, when the engagement protrusion 19 separates from the locking portion 3a, it enters the bag portion 3c and locks on the bag portion 3c. For this reason, the container 1
Of the container 1 is prevented from coming off the lid 1, and the container is prevented from falling.

When the container 1 and the lid 10 are to be separated from each other, the lid 10 and the container 1 can be relatively rotated by moving the engagement projection 19 over the protrusion on the outlet side of the bag portion 3c and rotating the lid 10 and the container 1 relatively. Can be released.

When the horizontal groove 3ab of the engagement groove 3 is formed to extend in the direction opposite to the rotation direction of the rotating body 20,
When the engaging projection 19 is located in the middle of the horizontal groove 3ab,
When the food stored in the container 1 is rotated by the rotation of the rotating body 20 when is not rotated to the predetermined position,
The container 1 is also applied with a force in the direction of being swirled by friction, which is a force for advancing the engaging projection 19 toward the depth of the horizontal groove 3ab, and thus preventing the lid 10 from coming off the container 1. Can be.

In the above embodiment, the engaging grooves 3 and 3 are formed in the opening 2 of the container 1 and the engaging projections 19 and 19 are formed on the peripheral wall of the lid 10. The engagement protrusions 3 and the engagement protrusions 19 may be formed in reverse, that is, the engagement protrusion may be formed on the opening 2 of the container 1 and the engagement groove may be formed on the peripheral wall of the lid 10. However, when the engagement groove is formed on the peripheral wall of the lid 10, the position of the guide portion 3a and the bag portion 3c is inverted upside down.

Further, in the case of the above embodiment, the O-ring 17 is loosely inserted into the insertion wall 7 and does not come into contact with the inner peripheral wall 7a during the relative rotation of the lid 10 and the container 1, so that the rotation operation is light. Although the case where the operability is improved and the operability is improved has been described, the present invention is not limited to this, and the O-ring 17 may be in contact with the inner peripheral wall 7a of the insertion wall 7 during the rotation operation. However,
When the O-ring 17 is configured not to contact the inner peripheral wall 7a of the insertion wall 7 during rotation as in the above-described embodiment,
Since the container 1 can be easily rotated with respect to the lid 10, the lid 1
When the container 1 is suspended while holding the container 0, there is a risk that the container 1 will rotate and fall off even if an inadvertent small rotational force is applied. It is effective.

The present invention can be implemented even when the O-ring 17 is attached to the container 1 side.

[0083]

As described above, according to the present invention, the lid can be rotated with respect to the container to be attached and detached by the guide of the engagement protrusion being guided by the guide portion of the engagement groove. In addition, if a force is applied in a direction in which the lid and the container are inadvertently separated, the engaging projections are engaged with the inner portion of the guide portion until then.
The lid enters the bag provided above the stopped locking portion to prevent relative rotation between the lid and the container. Therefore, separation of the lid from the container can be prevented, and problems such as inadvertent exposure of the rotating body and dropping of the container can be prevented.
