Abstract

(57) [Abstract] [Purpose] Recently, magnetic fasteners have become popular as bag metal fittings, but since the magnet case is attached to the front side of the bag material, it has a protruding shape, so the thickness of the metal fitting when the lid is closed. There is a gap between the lid and the lid, and it may get caught and come off, so the purpose of this plan is to eliminate the gap by incorporating the protrusion inside the material. [Structure] This is a magnet type metal fitting which is wound around a magnet case 2 by a surface cover 1 to be integrated, a magnet 7 is inserted from below, fixed by a pressing plate 5 and closely attached to a material 9.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure in which a magnetic stopper, which is often used for a mouthpiece of a bag or the like, is easily detached because a magnetic stopper is raised on the surface of the material and a gap between the lid and the lid is too open.

[0002]

[Prior art]

 In recent years, powder metallurgy magnets have been on the market, and since the magnetic type fasteners can be opened and closed very easily, they have been incorporated as bag mouthpieces and have been well received by users. As shown in Fig. 12, the poles in the recesses of the magnet and the protrusions of the mild steel were simply fitted and stuck together. Since the magnet needs to have a certain thickness, if the metal fitting contained in the magnet cover is attached to the bag, it will become a protrusion and there will be a lot of gaps even if the lid is closed, and the lid will be caught when carrying around with people etc. There was a chance to open.

[0003]

[Issues to be solved by the device]

 In the present invention, the stopper of the bag-type magnetic mouthpiece or the like can be removed only when the user tries to open it, and the structure is such that the lid does not open due to being caught, and the opening and closing operation is performed with the conventional bag. The object is to provide a magnetic fastener that does not change.

[0004]

[Means for solving problems]

 In the fastener according to the present invention, the magnet case 2 is incorporated in the surface cover 1, and the outer peripheral portion of 1 is thinly wound in a brim shape and compressed to increase the surface area and thin the protrusions on the surface of the material. Is fixed by the fitting press ring 8 and the press plate 5.

[0005]

[Action]

 Explaining the bag, when the magnet side is attached to the bag body and the mild steel side is attached to the lid, when closing the lid, the lid is inserted vertically with the convex portion of the mild steel into the magnet side. But, it sticks and fixes.

[0006]

【Example】

 FIG. 1 is a cross-sectional view of the surface cover, and FIG. 9 is inserted into the central hole and fixed by suction in a peripheral ring-shaped recess. As for the bent part around it, the powder metallurgy magnet shown in Fig. 5 is housed in Fig. 6 and the notched side at the bottom of Fig. 6 is fixed by bending with the built-in mild steel fitting shown in Fig. 9, and the circumference of Fig. 1 is surrounded. It is a structure in which the parts are rolled up and compressed to be in close contact. Fig. 11 is an assembled sectional view. A hole through which the magnet case passes is opened in the material of 9, and the surroundings are held down by the ring of 8 to fix the built-in metal fitting of Fig. 9 by the holding plate of 7. Therefore, regarding use, It is no different from the conventional one.

[0007]

[Effect of device]

 Unlike the conventional ones, the use of the magnetic stopper with the structure of the present invention has a high adsorption density on the contact surface of the bracket and a narrow gap, so there is almost no danger of it getting caught and disengaged. It does not easily come off, and the opening and closing operation is almost the same as the conventional magnetic metal fittings for bags.
