Description

Container-mounted container {CONTAINER WITH COVER}

The present invention relates to a container to which a lid is attached.

For example, there is a container provided with a lid having a function of keeping a warm / cool function by a container body having a vacuum insulation structure (see, for example, Patent Documents 1 and 2). In such a container having a lid, a structure is employed in which an opening provided in the container body is sealed by using an inner lid and an outer lid.

Specifically, the container to which the lid is attached includes a container body provided with an opening at an upper portion thereof, an inner lid which closes the opening portion in a state of being inserted into the inner side of the container body from the opening portion, (Seal member) for sealing between the cap and the cover, and an outer cover which is mounted on the container body by screwing in a state in which the opening is covered from the outside. The outer lid is brought into contact with the inner lid when the outer lid is attached to the container main body, thereby regulating the movement of the inner lid to the upper side.

Further, the container with the lid is structured such that an air hole provided in the inner lid closes the closing packing (parcel) provided on the outer lid. In the container having the lid, when the outer lid is removed from the container body, the clogging of the air hole by the closing packing is released. Thus, even when the pressure in the container body is reduced (negative pressure), since the outside air is introduced through the air hole when the outer cover is removed from the container body, the pressure in the container body is equal to the atmospheric pressure . Therefore, the inner lid is not pulled to the inside of the container body, and it is possible to easily detach the inner lid from the container body.

In the container 1 with the lid attached as described above, when the pressure in the container main body 2 is raised (positive pressure), the pressure of the inside of the container main body 2 is raised by the pressure inside the container main body 2, And is pressed against the cover 8. At this time, the fastening force by screwing between the container body 2 (the male thread portion 12) and the outer lid 8 (the female screw portion 11) is increased, so that the lid body 3 (8)) in the direction of removing it.

In this case, the operation of detaching the canopy 10 is performed. That is, when the canopy 10 is detached from the inner lid 9, the abutment of the protrusion 25a against the air hole 23 is released in the container 1 with the lid attached, 23 are opened. As a result, the pressure in the container body 2 is released through the air hole 23, so that the pressure in the container body 2 becomes equal to the atmospheric pressure. Thus, the state in which the inner lid 9 is pushed against the outer lid 8 is released, and it is possible to rotate the outer lid 8 easily in the direction in which the outer lid 8 is removed. As a result, it becomes possible to easily remove the lid body 3 (the outer lid 8 and the inner lid 9) from the container main body 2.

Since the area occupied by the pressure in the container body 2 with respect to the protruding portion 25a closing the air hole 23 is relatively small, even if the pressure in the container body 2 rises, The force is small. Thereby, even when the pressure in the container main body 2 is increased (positive pressure is applied), the canopy 10 can be easily rotated in the detaching direction.

Likewise, even when the pressure in the container body 2 is lowered (negative pressure), the pressure in the container body 2 becomes equal to the atmospheric pressure through the air hole 23 by removing the canopy 10 . The inner lid 9 is not pulled inward of the container body 2 and the lid body 3 (outer lid 8 and inner lid 9) is easily detached from the container body 2 It is possible.

When the contents in the container main body 2 are raised (positive pressure), for example, when a high temperature content is put in the container main body 2, And the like. On the other hand, a case where the pressure in the container main body 2 is lowered (negative pressure) can be exemplified when the contents are cooled after putting high temperature contents in the container main body 2 .

As described above, according to the present invention, even when the pressure in the container main body 2 rises or the pressure in the container main body 2 drops, a lid which can easily and safely detach the lid body 3 is attached It is possible to provide the container 1 which has been subjected to the heat treatment.

In addition, the present invention is not necessarily limited to the configuration of the container 1 to which the lid is attached, and various modifications can be made within the scope of the present invention.

Specifically, in the container 1 with the lid attached thereto, an air hole 23 is provided in the bottom surface portion 9a of the inner lid 9, and a stopper 24 (Fig. The elastic member 25 is mounted on the bottom surface portion 10c of the canopy 10 but the present invention is not limited to this configuration and the configuration as shown in Fig. 5 is a cross-sectional view of the main part showing a modified example of the container 1 to which the cover is attached.

5 has a structure in which the inner lid 9 is provided with a mounting hole 27 penetrating the central portion of the bottom face portion 9a and the elastic member 28 is detachably attached to the mounting hole 27 Respectively. At the center of the elastic member (28), an air hole (29) penetrates. On the other hand, the stopper section 24 for closing the air hole 29 is formed of the protruding portion 30 protruding downward from the central portion of the bottom surface portion 10c of the canopy 10.

In the case of the configuration shown in Fig. 5, it is possible to close the air hole 29 by abutting the projection 30 on the upper surface of the elastic member 28. [ Therefore, in this configuration also, by removing the canopy 10 from the inner lid 9, the abutment of the projection 30 with respect to the air hole 29 is released, and the air hole 29 is opened State. This makes it possible to easily remove the lid body 3 (the outer lid 8 and the inner lid 9) from the container body 2.

The size of the air hole 23 and the shape of the protrusion 25a are changed in the container 1 with the lid attached so that the abutment of the protrusion 25a with respect to the air hole 23 You can adjust the force. Thereby, even when the contents in the container body 2 are corrupted and the pressure in the container main body 2 excessively increases, for example, before the load such that the outer lid 8 is pulled out is applied, It is also possible to automatically open the pressure in the container body 2 from the air hole 23 by releasing the abutment of the projecting portion 30 with respect to the container body 29. [

Although the inner lid 9 is detachably mounted to the outer lid 8 in the container 1 with the lid attached thereto, the outer lid 8 is not limited to this configuration, (9) may be integrally formed. The outer lid 8 and the inner lid 9 may be separately mounted on the container main body 2. The canopy 10 is detachably attached to the inner lid 9 in the container 1 to which the lid is attached. However, the configuration is not limited to this, and the outer lid 8 may be provided with the canopy 10 Can be detachably mounted.

The present invention can be suitably applied to a container to which a lid having a function of keeping a warm / cool function is attached by a container body having a vacuum insulation structure. However, it is also possible to use a lid including a container body provided with the opening portion described above, It is possible to widely apply the present invention to a container having a cover provided thereon.
