Further, since the non-cut portion of the thin broken portion 8 becomes the connecting portion 26 when the lid member 3 is pushed down, it also has the advantage that the disadvantage that the entire thin broken portion 8 is cut and dropped can be reliably prevented. Yes.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 6 show an example of the cap of the present invention. The cap A includes a cap body 2 and a lid member 3, both of which are made of synthetic resin.

  The cap body 2 has a flange 6 extending inwardly from the upper end of the mounting cylinder 5 fitted to the outer periphery of the mouth part 4 of the container B, and has a bottomed cylindrical shape in the mouth part 4 from the inner peripheral edge of the flange 6. The storage cylinder 7 is suspended. The storage cylinder 7 has a bottom wall portion 7b extending from the inner peripheral edge of the flange 6 to the lower end portion of the peripheral wall portion 7a that hangs down into the mouth portion 4 via a thin-walled fracture portion 8, and the inside is configured as a storage chamber R. is doing.

  In the illustrated example, a sealing ring 10 is suspended from the lower end edge of the mounting cylinder 5 via a breakable portion 9 that can be easily cut, and an engaging ridge 11 projecting from the inner periphery of the sealing ring 10 is provided as a container opening. The lower surface of the locking ridge 12 protruding from the outer periphery of the portion 4 is overcome and engaged. Accordingly, the cap main body 2 cannot be removed unless the easily cut breakable portion 9 is cut.

  The lid member 3 includes a cutter cylinder 20 slidably fitted to the peripheral wall portion 7a, suspended from the back surface of the top plate 21, and a pair of opposed notch portions 22 provided at the lower end of the cutter cylinder 20 The lower end edge is formed in the annular cutter blade s. In the illustrated example, a cylindrical cutter cylinder 20 is suspended from the center of the back surface of a disk-shaped top plate 21, and a pair of mountain-shaped notches 22 are provided before and after the cutter cylinder 20. The cutter blade s has a sharp tip, but if the thickness of the cutter cylinder 20 is taken into consideration, the function as a cutter can be sufficiently exerted even if the lower end surface is flat. Since the cutter blade s has a pair of opposing chevron-shaped notches 22, for example, when there is a chevron-shaped notch 22 at the front and rear, the thin fracture portion 8 is cut from the left and right when the lid member 3 is pushed down. To go. The pushing width and the cut width of the notch 22 are set so that the front and rear center portions remain as non-cut portions.

  In addition, a pair of pressing portions 23 are provided in the middle of each chevron-shaped notch 22 on the inner surface of the cutter cylinder 20. The pressing portion 23 is for lowering the upper surface of the bottom wall portion 7b that is cut as it descends, and deforming the bottom wall portion 7b into a mountain shape. Therefore, after the cutter blade s cuts the thin-walled fracture portion 8, Projection is provided so that the front end of the lower surface is located at the position where it is pushed down. In this case, the thin broken portion 8 can be configured to be pressed after a predetermined cut portion is cut forward, or can be configured to be sequentially pressed during cutting. In the illustrated example, the inner surface of the cutter cylinder 20 protrudes in the form of a vertically long rectangular plate on the left and right sides.

  Further, a ring-opening band-shaped sealing band 24 that prevents the lid member 3 from being pushed down is provided. This sealing band 24 is connected to the peripheral edge of the top plate 21 of the lid member 3 so as to be cut, and is connected to the outer peripheral edge of the top plate 21 via an easily cutable rupture portion 25 constituted by a plurality of rod-shaped connecting pieces in the circumferential direction. The upper edge is connected, and the lower surface is placed in contact with the cap body 2. Thus, the lid member 3 is prevented from being pushed down, and the container B mounted with the sealing ring 10 can be expressed as unused.

  The case where the cap A configured as described above is used will be described. First, the cap A filled with the stored item in the storage chamber R is screwed into the container B filled with the stored item. At this time, the engaging ridge 11 of the sealing ring 10 forcibly climbs over the locking ridge 12 of the container mouth 4 and engages the lower surface thereof. As a storage thing filled in the storage chamber R of the container B and the cap A, a liquid thing or solid things, such as a powder and a granule, etc. can be stored.

  In the case of using a container, the sealing band 24 is removed from the state shown in FIG. 1 by cutting the easily cuttable breaking portion 25, and then the top plate 21 is pushed to push down the lid member 3. First, both sides of the thin-walled fracture portion 8 are cut by the cutter blade s, and are sequentially cut from the both sides to the center side as the lid member 3 is pushed down. When the cutting progresses to a certain extent, the pressing portion 23 starts to push down by the upper surface of the bottom wall portion 7b, and the cut bottom wall portion 7b is surely pushed down, and finally transformed into a front-view mountain shape as shown in FIG. Opening R, the stored item in the storage chamber R falls into the container B, and both are mixed. After mixing, if the cap body 2 is unscrewed from the mouth 4 of the container B, the easy-cut breakable part 9 is cut and the sealing ring 10 remains in the container mouth 4 as shown in FIG. All can be removed and mixed contents can be used.

  Further, the thin broken portion 8 may be provided with a pair of connecting portions 26 facing each other as shown in FIG. By providing this connecting portion 26, it is possible to reliably prevent inconveniences such as the entire thin broken portion 8 being cut and the bottom wall portion 7b falling into the container. In this case, the lid member 3 may be fitted so that the top of each chevron-shaped notch 22 of the cutter cylinder 20 corresponds to a position corresponding to each connecting portion 26.

  Further, in the present invention, a positioning mechanism for defining the insertion position of the lid member 3 with respect to the cap body 2 is provided, and a pair is provided at a predetermined opposing position corresponding to the top of each chevron-shaped notch 22 of the thin fracture portion 8 of the cap body 2. A connecting portion may be provided. As an example of the positioning mechanism, for example, the storage cylinder peripheral wall 7a of the cap body 2 is formed in a non-circular shape such as an ellipse, and the cutter cylinder 20 of the cover member 3 is formed in the same shape, so that the cover member is placed at a predetermined insertion position. 3 can be inserted. At this time, since the position of the chevron-shaped notch 22 is also specified, if a pair of connecting portions are formed at the opposing positions of the thin-walled rupture portion 8 corresponding to the top, the top of each chevron-shaped notch 22 and each The position with the connecting portion 26 matches. Further, as the positioning mechanism, a positioning mechanism including a protrusion and a concave groove may be provided on the opposing surface of the storage cylinder peripheral wall portion 7a and the cutter cylinder 20.
