BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, the container of the present invention has a container main body 1, a lid body 2, and a supporting portion 3 as a basic structure. As shown in FIG. 2, the container body 1 is a plastic molded product having a bottomed tubular shape as a whole,
An opening 11 is provided in the upper part. A main body side jaw portion 12 that engages with the lid body 2 is provided on the outer periphery of the opening 11 so as to project outward in the radial direction, and below the main body side jaw portion 12 is engaged with the support portion 3. A concave portion 13 is provided.

The lid body 2 and the support portion 3 are integrally molded of a plastic softer than the container body 1 together with a connecting piece 20 and a belt-like member 21 for connecting them. The appearance is as shown in FIG. 3, and the support portion 3 and the lid body 2 are connected to each other by a plate-like connecting piece 20 at a part of the outer circumference. A space is provided between the lid body 2 and the support portion 3 in the axial direction (left and right direction in FIG. 3b), and the belt-shaped members 21 provided at the space are connected to each other over a predetermined range in the circumferential direction. (At least a part is provided with a region where the belt-shaped member 21 does not exist).

The support portion 3 is formed in an annular shape so that it can be tightly fitted to the outer periphery of the container body 2, and the inner periphery of the support portion 3 is shown in FIG.
As shown in (b), a convex portion 22 that engages with the concave portion 13 of the container body 1 to fix the support portion 3 tightly to the container body 1 is formed. In addition, these concave portion 13 and convex portion 22
The fitting force due to is set to be sufficiently larger than the force required to cut the strip-shaped member 21 described later. A thin plate-shaped connecting portion 23 is provided between the strip-shaped member 21 and the support portion 3 and between the strip-shaped member 21 and the lid body 2 to facilitate cutting. One end of the strip-shaped member 21 is on one side of the connecting piece 20 (the connecting piece 2 in FIG. 3c).
0), and the other end is also on the other side (see FIG. 3).
It is arranged on the upper side of the connecting piece 20 in c). A knob 24 is provided at the other end of the connecting piece 20 so as to project radially outward. Further, the belt-shaped member 21 is separated from the lid body 2 and the support portion 3 in the vicinity of the other end portion where the knob 24 is provided, without providing the connecting portion 23. Further, an uneven portion 25 is provided in a predetermined range of the strip-shaped member 21 from the position where the knob 24 is provided. As a result, by gripping the knob 24 with a finger, the belt-shaped member 21 can be bent at the uneven portion 25 and easily pulled out.

An upper portion of the lid 2 is a disc portion 26, and a short cylinder portion 27 is provided along the outer periphery of the disc portion 26. That is, the lid body 2 is connected to the support portion 3 by the connecting piece 20 that is integral with the short tube portion 27 in a range where the band-shaped member 21 does not exist. At a position 180 degrees away from the connection point by the connection piece 20 in the circumferential direction,
An operating portion 28 is provided which is formed by projecting a part of the disk portion 26 outward in the radial direction. Further, the disc portion 26 is provided with ribs 29 having a larger thickness than the other portions of the disc portion 26 in order to increase the rigidity of the disc portion 26. Further, a lid side jaw 30 projecting inward is provided on the inner periphery of the short tubular portion 27, and the lid body side jaw 30 is a body side jaw 12 on the outer periphery of the opening 11 of the container body 1. The lid body 2 is fixed to the container body 1 by engaging with. Further, an annular projection 31 is provided on the lower surface of the disc portion 26 so as to project downward. The protrusion 31 is in contact with the upper surface of the opening 11 and is elastically deformed, thereby ensuring the sealing property with the container body 1.

Furthermore, the lid 2 has the short cylindrical portion 27.
An inner cylinder portion 32 is provided concentrically with. This inner cylinder part 3
2 is made of a softer plastic than the container body 1 so as to be elastically deformed along the inner circumference of the opening 11 of the container body 1 to come into contact with the opening 11, and is formed thin. The inner tubular portion 32 has a longest dimension L1 on the side where the connecting piece 20 is present so that the opening can be surely closed by opening / closing the lid 2, and the length is gradually set shorter toward the center. Has been done. Further, the length L2 is set to be constant from the center toward the anti-coupling side. Further, the outer circumference of the inner cylindrical portion 32 is a tapered surface 33 whose outer diameter is gradually reduced in a conical surface shape by decreasing the thickness toward the tip, as shown in FIG. 6 (c). As described above, the inner cylindrical portion 32 can be easily deformed by contacting the main body side jaw portion 13 of the container main body 1. The length L1 of the inner cylindrical portion 32 is as shown in FIG.
As shown in (b), the dimension at which the tip can contact the main body side jaw 13 in a state where the lid 2 is opened at a predetermined angle (for example, 60 degrees of the maximum opening / closing angle arbitrarily determined according to the required specifications). It is said that. As shown in FIG. 5, the length L2 is required to have a minimum dimension capable of coming into contact with the inner circumference of the opening 11 and ensuring sufficient airtightness, but the lid 2 is completely closed. In order to reduce the repulsive pressure when the lid body 2 is closed by bleeding air from the container body 1 to the outside air at the immediately preceding stage, it is desirable to make it as short as possible.

The operation of the container having the above structure will be described together with its opening / closing operation. First, hold the knob 24 of the belt-shaped member 21 and pull it outward in the radial direction. At this time, this knob 24
The strip-shaped member 21 is not connected to the support portion 3 and the lid 2 in the vicinity of, and since the uneven portion 25 is formed, the strip-shaped member 21 can be easily bent. A sufficient length for easy pulling and grasping can be secured, and the force required for tearing can be easily applied. Further, since the length required for the operation is secured by pulling out the knob 24 in this way, the protrusion amount of the knob 24 with respect to the container body 1 can be minimized. That is, it is possible to make the entire container as close to a cylinder as possible to improve the handleability by various handling devices such as a parts feeder.

When the knob 24 is further pulled, the belt-shaped member 21 is separated from the lid body 2 and the support portion 3 while tearing the connecting portion 23. When the band-shaped member 21 is removed by such an operation, the lid 2 is opened and the lid 2 can be opened and closed. Then, when the operating portion 28 is lifted up, the lid side jaw 30 is deformed so as to move diagonally upward to the left in FIG. 5, the engagement with the main body side jaw 12 is released, and at the same time, the lid 2 is moved upward. It is pulled up to and removed from the container body 1. It should be noted that this operation can be achieved by pinching the operating portion 28 with two fingers and pulling it up.
This can also be achieved by an operation of applying one finger (for example, the first finger) to the lower surface of the operation unit 28 and pushing it up. That is, hold the container body 1 with the second finger or less of one hand,
The container can be opened by a one-handed operation in which the first finger is applied to the lower surface of the operation unit 28 and pushed up.

In this way, with the operation of opening the lid body 2,
The connecting piece 20 connecting the lid body 2 and the supporting portion 3 is shown in FIG.
The state of (a) is gradually transformed into the states of (b) to (c). Generally, when the container is opened by the above operation, the lid 2
6 is once opened to the angle rotated further clockwise from the state of FIG. 6 (c), and when the pushing operation of the operating portion 28 with a finger or the like is stopped, the elastically deformed and curved connecting piece 20 tries to be restored. , The inner cylindrical portion 32 as shown in FIG.
Reaches the angle at which the tip of the contact with the vicinity of the opening 11 of the container body 1 and stands still in this state. In this way, the opening state can be maintained at a constant angle by the force of the elastically deformed connecting piece 20 to restore. That is, by selecting an appropriate value for the length L1 of the inner tubular portion 32, the position at which the lid 2 is opened and stopped is set at a desired angle (for example, 60).
It can be set to

On the other hand, the operation of closing the lid body 2 is performed as follows. When the operating portion 28 at the tip of the lid 2 is pushed downward, the counterclockwise force shown in FIG. 6C is applied to the lid 2, and the elastically deformed connecting piece 20 is restored while moving in the closing direction. To do. Tapered surface 3 at the tip of the inner tubular portion 32
3 contacts the vicinity of the opening 11 of the container 1 to guide the inner cylindrical portion 32 to the inside of the opening 11.

When the operating portion 28 is further pushed down, the inner tubular portion 32 is gradually inserted into the opening 11, and along with this, the short tubular portion 27 is elastically deformed outward, and the lid side jaw portion 30 is moved to the container side jaw. It is brought into the engaged state by overcoming the portion 12 and being pushed down, and by being pushed down from the container side jaw portion 12 and then restored. Further, since the inner cylinder portion 32 has a small length L2 on the side where the connecting piece 20 is not provided (the side on which the lid is finally covered in the operation of closing the container),
6 (a), the opening 11 is communicated with the outside air until the final closed state is reached by further rotating in the counterclockwise direction, and the container body 1 and the lid body 2 associated with the operation of closing the lid body 2 are closed. Less likely to be repulsed by air pressure between and.

When the operating portion 28 is continuously pushed down, the container side jaw 12 and the lid side jaw 30 are engaged with each other, and the operation of closing the lid 2 is completed. The engagement between the container-side jaw portion 12 and the lid-side jaw portion 30 is performed within a predetermined range from the operation portion 28 side to the connecting piece 20 side, and does not engage at the position where the connecting piece 20 exists. At this position, the length of the inner cylindrical portion 32 is sufficiently secured over L1 and can be in contact with the inner surface of the opening 11, so that the entire circumference of the container body 1 is sealed. At this time, the protrusion 3 on the lower surface of the lid body 2
1 contacts the upper surface of the container body 1 in an elastically deformed state, and seals between the container body 1 and the lid 2. Also, the lid 2
Since the disc portion 26 is provided with the rib 29, it is less likely to be deformed than other portions. Therefore, even if a force is applied only to the operating portion 28, the disc portion 26 is as if it were a rigid body.
It is possible to move without deformation and close the container while surely deforming the short cylinder portion 27 and the inner cylinder portion 32.

As described above, since the operation for opening and closing the container is achieved only by pushing up or pushing down the operating portion 28, it can be easily performed by one-handed operation using only the first finger.

The structure of the present invention is not limited to the above-mentioned embodiment, and it goes without saying that the structure may be appropriately changed without departing from the technical scope of the present invention. For example, it is needless to say that the shape of the other portion may be appropriately changed according to the quantity and quality of the contained items while securing the configuration as in the embodiment around the opening.

[0019]

As described above, according to the present invention,
Since the lid that covers the opening of the container body and seals it is provided with a short tube part of a predetermined length, the tip of the inner tube part will be the tip of the opening of the container body if the lid is within a predetermined angle. And the inner cylinder part is elastically deformed by the operation of closing the lid, and is inserted into the opening so that the inner cylinder part is brought into close contact with the opening.
The container can be reliably sealed. Further, since the supporting portion fixed to the container body and the lid are connected by the connecting piece, the opening can be closed or opened by operating the lid with one hand while the connecting piece functions as a hinge. it can. Further, since the inner cylindrical portion has the predetermined length in the vicinity of the area where the connecting piece is provided and is shorter than the other area in the other area, the inner cylindrical portion is elastically deformed to form a lid body. At the time of closing, the inner cylinder first touches the opening to guide the lid, and by letting air escape from other parts, repulsion due to air pressure at the final stage of the lid closing operation is reduced, and the minimum operation is performed. It can be operated by force. Further, since the lid body is fixed to the container body by the engagement between the body side jaw portion and the lid body side jaw portion, by applying a force to the outer periphery of the lid body with a finger, the lid body and the jaw portion on the outer periphery of the opening are engaged. You can take it off. Further, between the support and the lid,
A band-shaped member is provided which is connected to the lid support part and the lid body in a circumferential direction over a predetermined range, and the strength of the connection part is set to be smaller than that of the other parts, and the range in which the connection part exists in the band-shaped member. Other portions are provided with knobs protruding outward in the radial direction, and further provided with unevenness for facilitating bending of the belt-shaped member.By pulling the knob, the belt-shaped member is supported by the lid support portion. And can be separated from the lid. Further, the strip-shaped member is continuously provided in the circumferential direction of the lid body in the range from one side of the location where the connecting piece exists to the other side, and the one side or the other side. Since the knob is provided at either end, the strip-shaped member can be easily separated from the container. Further, since the operability of the knob is good, a minimum amount of protrusion is sufficient, and therefore, as a simple shape that approximates a cylinder to the entire container, good handling in an automatic transfer device is ensured, and it is suitable for a transfer container or the like. The filling efficiency at the time of filling can be improved. Further, since the disk portion of the lid body is provided with ribs whose rigidity is higher than that of the disk portion, the lid body has high rigidity and is necessary even when a part of the lid body is operated. The opening of the container body can be opened and closed by elastically deforming only the portion.
