Japanese Utility Model Publication No. 5-1702

  The present invention has been made in view of the above-described problems existing in the prior art, and its purpose is to maintain the airtightness as much as possible when the open / close lid is closed. An object of the present invention is to provide a compartment opening / closing device capable of suppressing as much as possible the sound generated when the opening / closing lid closes.

(1) A compartment opening / closing device of the present invention for solving the above problems is
A compartment that divides the first part and the second part;
An opening that is provided in the compartment and can communicate the first part and the second part;
A peripheral wall-like portion surrounding the opening on the second portion side;
An opening / closing lid that can open and close the peripheral edge of the tip of the peripheral wall-shaped part;
The peripheral wall-shaped portion has a distal end side constituted by a soft peripheral wall portion, and a proximal end side constituted by a hard peripheral wall portion,
The opening / closing lid is in contact with the peripheral edge of the peripheral wall-shaped portion and closed to close the distal end of the peripheral wall-shaped portion, and is pushed from the first part side to the second part side through the opening and the peripheral wall-shaped part. It is possible to take an open state in which the distal end portion of the peripheral wall-shaped portion is open, and a force for making the closed state act on the open / close lid.

  An opening / closing lid is used to open and close the peripheral edge of the peripheral wall-like portion that is provided in the partition that divides the first part and the second part and communicates the first part and the second part on the second part side. obtain.

  The opening / closing lid is in a closed state in which the distal end portion of the peripheral wall-shaped portion is closed in contact with the peripheral edge portion of the peripheral wall-shaped portion, and the peripheral wall by being pushed from the first part side to the second part side through the opening and the inside of the peripheral wall-shaped portion. It can be in an open state in which the tip of the shape portion is opened. Since the opening / closing lid is subjected to a closing force, the opened lid is automatically closed.

  Since the distal end side of the peripheral wall portion is composed of a soft peripheral wall portion, when the open / close lid is closed in contact with the peripheral edge portion of the peripheral wall portion, the sound during closing is suppressed and airtightness in the closed state is achieved. As a result, the odor is prevented from leaking from the second part to the first part, which is suitable for indoor use. In addition, since the distal end side of the peripheral wall-shaped portion is constituted by a soft peripheral wall portion, it is possible to prevent the operator from being injured by the peripheral edge portion of the peripheral wall-shaped portion in the operation from the first part side to the second part side. Is done.

  (2) The soft peripheral wall portion on the distal end side and the hard peripheral wall portion on the proximal end side in the peripheral wall-shaped portion may be integrally formed.

  In this case, the peripheral wall-shaped portion can be efficiently manufactured by integral molding, and the soft peripheral wall portion on the distal end side can be prevented from being partially separated from the hard peripheral wall portion on the proximal end side due to long-term use or the like.

  (3) The soft peripheral wall portion on the distal end side and the hard peripheral wall portion on the proximal end side in the peripheral wall-shaped portion may be integrated with no gap or step between them.

  In this case, when an object is fed from the first part side to the second part side through the inside of the opening and the peripheral wall-shaped part, there are various between the soft peripheral wall part on the distal end side and the hard peripheral wall part on the proximal end side in the peripheral wall-shaped part. This prevents things from getting caught or pinched.

  (4) The force for acting on the open / close lid and closing the open / close lid may be gravity acting on the open / close lid.

  (5) Further, the force for acting on the open / close lid to close the open / close lid may be an elastic force generated by an elastic material that directly or indirectly cooperates with the open / close lid.

  (6) The second part may be an object storage unit.

  According to the compartment opening / closing device of the present invention, since the distal end side of the peripheral wall-shaped portion is configured by the soft peripheral wall portion, the closing sound is suppressed when the open / close lid is closed in contact with the peripheral edge portion of the peripheral wall-shaped portion. At the same time, since the airtightness in the closed state is increased as much as possible, the odor is prevented from leaking from the second part to the first part, which is suitable for indoor use. In addition, since the distal end side of the peripheral wall-shaped portion is constituted by a soft peripheral wall portion, it is possible to prevent the operator from being injured by the peripheral edge portion of the peripheral wall-shaped portion in the operation from the first part side to the second part side. Is done.
