Abstract
Description
Technical Field
[0001] The present invention relates to a locking mechanism for a lid body of a compact case in which the lid body is hinged to be freely opened and closed by a hinge and uses a magnet.
Background Art
[0002] Conventionally, many configurations have been proposed in which magnets are embedded in the main body and the lid body of a compact case in which the lid body is hinged to be freely opened and closed by a hinge, and the magnets are used for locking and releasing the lid body.
[0003] Among these, the configuration of Patent Document 1 is such that one pole portion of a magnet magnetized on both sides with two poles is fixed to the upper surface of a slide-type push button provided on the main body of a compact container in which the main body and the lid body are connected by a hinge so as to be freely opened and closed. On the lower surface of the lid body, two similarly magnetized magnets are fixed at positions facing the magnet of the push button at the front and rear ends of the slide range of the push button, with one pole portion facing the lower surface. The magnet at the front of the main body that faces the advancing end position of the push button has a different pole from the magnet of the push button, and the magnet at the back of the main body that faces the retreating end position of the push button has the same pole as the magnet of the push button facing it. Thus, when the push button is at the advancing end, the magnets face each other with different poles and attract (lock the lid body), and when at the retreating end, the magnets face each other with the same pole and repel (open the lid body).
[0004] Also, the configuration of Patent Document 2 is such that one pole portion of a magnet magnetized on both sides with two poles is fixed to the lower surface of the lid body of a compact container in which the main body and the lid body are connected by a hinge so as to be freely opened and closed, with the pole portion facing the lower surface. A magnetic body is fixed to the upper surface of a slide-type push button provided on the main body at a position facing the magnet of the lid body at the advancing end position of the push button, and a similarly magnetized magnet is fixed at a position facing the magnet of the lid body at the retreating end position of the push button, with the same pole as the magnet of the lid body facing it. Thus, when the push button is at the advancing end position, the magnet of the lid body is attracted to the magnetic body of the push button (lock the lid body), and when the push button is at the retreating end position, the magnet of the lid body and the magnet of the push button face each other with the same pole and repel (open the lid body).
[0005] Furthermore, the configuration of Patent Document 3 involves a compact container in which the main body and lid are connected by a hinge so that they can be opened and closed. Two magnets, each magnetized with alternating poles on one side, are fixed opposite each other to the upper surface of a slide-type push button on the main body and the lower surface of the lid. The poles of each magnet are positioned perpendicular to the slide axis of the push button. However, these two magnets are positioned so that opposite poles face each other when the push button is at its forward end, and like poles face each other when the push button is at its retracted end. As a result, at the forward end of the push button, the magnet of the push button and the magnet of the main body face opposite poles and attract each other (locking the lid), and at the retracted end of the Oshida design, the magnet of the push button and the magnet of the main body shift and face each other with like poles, causing them to repel each other (opening the lid). Moreover, because the opposite poles of the two magnets on one side face each other, the attractive force when the magnets of the lid and the push button are completely opposite poles was much greater than the attractive force when the opposite poles face each other of magnets with two poles on both sides.
[0006] In these configurations, there is no need for protrusions such as hooks to hold the lid closed, resulting in a simple and clean appearance for the compact container. Furthermore, because the lid is held in place by magnetic attraction, it does not involve deformation-inducing engagements such as undercut engagements, and there is no impact or distortion during engagement, thus preventing damage to the cosmetics contained within. In addition, when the lid is opened, the magnets in the lid and the magnets in the push button repel each other, causing the lid to lift slightly, preventing it from closing again and making it easier to grasp.

[0007] [Patent Document 1] Japanese Utility Model Publication No. 59-34707 [Patent Document 2] Japanese Utility Model Publication No. 55-161909 [Patent Document 3] Japanese Utility Model Publication No. 55-62225 [Overview of the project] [Problems that the invention aims to solve]
[0008] However, since the lid is kept closed solely by the magnetic attraction, the closing force is weaker compared to closing mechanisms such as hooks. Therefore, a fairly strong magnetic force was needed to prevent it from opening unintentionally when carrying it.
[0009] The configuration described in Patent Document 1 maximized the magnetic attraction force because the opposite poles of the magnets faced each other when the lid was closed. However, this configuration required three magnets, which increased costs.
[0010] The configuration described in Patent Document 2 consists of two magnets and one magnetic material such as iron, with the magnets being attracted to the magnetic material when the lid is closed. Compared to the configuration in Patent Document 1, one less magnet was needed. However, the magnetic material that attracts the magnets also requires rust prevention treatment such as plating, so the cost reduction was small.
[0011] Furthermore, the configuration in Patent Document 3 switched between attraction and repulsion by the misalignment of a magnet with two poles magnetized on one side. Therefore, it required one less magnet than the configuration in Patent Document 1 and no magnetic material than the configuration in Patent Document 2. Also, because the opposing poles of this magnet attracted two poles together, the attraction force was strong. However, the repulsive force when the magnets were of the same pole was weaker than when they were attracted because only one pole was involved, and therefore could not be said to be equivalent. [Means for solving the problem]
[0012] The container body 2 and the lid 3 are hinged together with a hinge 4 so that they can be opened and closed. The aforementioned Container body 2 or the above A push-button-shaped sliding member 6 is positioned on either side of the lid 3 so as to be able to slide back and forth.

In other words, when the slide member 6 is at its forward end, the hook portion 351 and the engaging projection 622 engage in a bolt-like manner, holding the lid 3 closed, and the diagonal repulsive force P of the magnets 7 and 9 becomes a horizontal stress F1 that presses the slide member 6 to its forward end. Furthermore, when the slide member 6 is at its retracted end, the engagement between the hook portion 351 and the engaging projection 622 is released, allowing the lid 3 to be opened, and the diagonal repulsive force P of the magnets 7 and 9 becomes a vertical stress F3 that pushes the lid 3 upward. As a result, compared with the lid locking mechanism using magnets as in Patent Documents 1 to 3, while improving the closing strength, reliability, and operability of the lid, the number of magnets is reduced to a minimum of one pair (two), reducing the magnet cost.
[0014] Furthermore, the bolt-like hook engagement between the hook portion 351 and the engaging projection 622 is The aforementioned The sliding of the slide member 6 The aforementioned Hook part 351 and The aforementioned The engaging projection 622 Horizontal Because it is a snag, it is not a crossover engagement like an undercut engagement, but rather a crossover engagement. relative to the container body No impact or distortion occurs, and the contents inside the container body 2 are not adversely affected.

[Claim 1] The container body (2) and the lid (3) are hinged together by a hinge (4) so that they can be opened and closed, and a push-button-shaped sliding member (6) is positioned on either the container body (2) or the lid (3) so that it can slide back and forth, and a hook portion (351) is provided on either the lid (3) or the container body (2) opposite the sliding member (6), and a engaging projection (622) is provided on the other, and the hook portion (351) and the engaging projection (622) engage in a bolt-like manner when the sliding member (6) is at its forward end to hold the container body (2) and the lid (3) closed, and the engagement is released when the sliding member (6) is at its retracted end, A magnet (7) is placed on the slide member (6), and a magnet (9) is placed on the lid (3) or the container body (2) opposite the slide member (6), with the same poles facing each other, and the magnet (7) on the slide member (6) and the magnet (9) on the container body (2) or lid (3) opposite the slide member (6) are such that, at any position between the forward end and the retracted end of the slide member (6), one of the magnets (7) is offset more toward the forward end of the slide member (6) than the other magnet (9). A locking mechanism for a lid in a compact case, characterized in that the diagonal repulsive force (P) due to the misalignment of each magnet (7, 9) becomes a horizontal stress (F1) that pushes the sliding member (6) toward the forward end, and a vertical stress (F3) that pushes up the lid (3) from which the engagement has been released.
