  Each of the above-mentioned containers is excellent in that it can be discharged or drawn out in its respective form according to the use, physical properties, etc. of the stored item. There is an inconvenience that a plurality of containers must be prepared to meet the demand.

  The present invention proposes a cap capable of selecting a plurality of types of opening forms with a simple operation and discharging or swinging out a plurality of forms. In addition, a cap having a simple structure and easy to manufacture at low cost is proposed.

  The cap of the present invention includes a cap body, a rotating plate, and a lid.

  The cap of the present invention is used by being attached to a container body. However, the container body is not particularly limited as long as it has a mouth and neck portion, and may be appropriately selected depending on the kind of stored items. For example, when the stored item is a high-viscosity liquid, a tube container having an elastic restoring force and having a squeezable body portion can be preferably used. In some cases, a normal bottle type container can be used.

  The cap body is formed of a synthetic resin or the like, and has a through-hole for discharging stored items on a top plate that fits into the mouth and neck of the container body and covers the upper opening of the mouth and neck. As a general form, the top plate has a top-bottom cylindrical shape with a top plate extending from the top end of the peripheral wall to be fitted to the outer periphery of the mouth and neck, and a through hole is formed in the top plate. The through-hole drilling position may be provided at the center of the top plate of the cap body or at an eccentric position, and may be appropriately selected in conjunction with the installation position of the rotating plate.

As a means for rotating the rotating plate, there are a case where it is configured to be able to rotate in the closed state and a case where it is configured to be able to rotate in the opened state. In the former case, for example, What is necessary is just to comprise so that the part can be exposed and rotated from between a cap main body and a cover body. In that case, a knurling for preventing slipping may be provided on the outer surface of the rotating plate. In the latter case, after the lid is opened, a portion protruding from the upper surface of the rotating plate, for example, a protruding portion having an opening is grasped and rotated, or a protrusion for hooking a finger is formed on the rotating plate. You may comprise so that it may protrude and may be rotated with the protrusion.

  In the rotating plate, a plurality of openings having different opening forms are arranged on a central circle that matches the through hole. Examples of different types of openings include a difference in diameter and a difference in the cross-sectional shape of the opening, or a single or plural differences. The plurality of cases is a case where an assembly of a plurality of small holes is configured as one opening. The number of openings is not limited, but considering the size of this type of cap, 3 to 4 are considered to be reasonable numbers, but of course not limited thereto. Further, the arrangement on the center circle that coincides with the through hole means that the distance from the center of the rotating plate to the through hole (exactly of course has a predetermined width) is located on the circumference having a radius. . Furthermore, the position where the rotating plate is installed on the cap body depends on the position of the through holes for discharging the stored items provided on the cap body. When the through hole is provided at the center of the top plate of the cap body, the center of the rotating plate is decentered from the center of the cap body. Further, when the through hole is provided at a position eccentric from the center of the top plate of the cap main body, for example, the center of the rotating plate can be positioned at the center of the cap main body.

  In addition, it is preferable to provide a position matching detection means for detecting a state in which the opening of the rotating plate and the through hole are matched so as to communicate with each other. The position detection means can adopt various forms as long as any one of the openings and the through hole of the cap main body can be detected, but for example, it can be applied to one of the opposing surfaces of the rotating plate and the cap main body. It can be configured by providing a mating protrusion and an engaging recess on the other side. For example, one engagement protrusion is provided at a predetermined position on the lower surface of the rotating plate, and the number of engagement recesses corresponding to the number of openings is provided at a predetermined position on the upper surface of the opposing cap body. The through-hole and each opening are configured to coincide with each other at a position where the engaging recess engages. In this case, the number of engaging protrusions may be the same as the number of engaging recesses, the engaging protrusions may be provided on the upper surface of the cap body, and the engaging recesses may be provided on the lower surface of the rotating plate. As another example, a mark may be provided on the rotating plate and the cap body, and the openings may be matched with each other by matching them.

  The lid is made of a synthetic resin that can be opened and closed on the cap body. It may be formed separately from the cap body, and the peripheral wall may be screwed to the outer periphery of the cap body. It is preferable to use one that is pivotably connected to each other and can be opened and closed. In particular, a cap body and a lid that are integrally formed can be used more preferably. A plug may be provided on the back surface of the lid. This stopper is fitted by closing the opening of the rotating plate at a position communicating with the through hole of the cap body, and it can leak stored items and provide airtightness in the container body, and the rotating plate is unnecessary.
