等)。2. Description of the Related Art Conventionally, a container is filled with a content liquid and capped, and then, the liquid is attached to the cap to clean the remaining content liquid adhering between the outer peripheral surface of the container opening and the inner peripheral surface of the cap. The cleaning liquid is sprayed by the above method to flow the cleaning liquid into the inside of the cap. As a cap that can be cleaned by spraying such a cleaning liquid, for example,
There has been proposed a cap in which a plurality of holes are formed at intervals in the circumferential direction on at least one of the top surface peripheral portion and the skirt portion of the cap (Japanese Utility Model Publication No. 4-54119, etc.).

727号公報)。Since the cap having a plurality of holes as described above is required to be as small as possible in view of dust and appearance, the tamper-evidence band is generally formed after the cap is molded. It is formed by making a notch in the skirt with a cutter or the like together with the formation of the TE band (hereinafter referred to as "TE band")
-208693). On the other hand, in the cap having such a hole as small as possible, it is difficult to sufficiently flow the cleaning liquid into the cap. Therefore, as a method of efficiently flowing the cleaning liquid into the cap, It has been proposed to spray a cleaning liquid of 65 ° C. or higher, or to heat the cap to 70 ° C. or higher and then spray a cleaning liquid of 45 to 70 ° C. (JP 2000-85A).

封性に問題を起こす可能性がある。According to the above method, the inside of the cap can be efficiently cleaned, but in the above method, the container mouth and the cap are heated to a relatively high temperature. , For example, it cannot be applied to aseptically filled containers and caps. That is, in a container to which aseptic filling is applied,
Since it does not require heat sterilization after filling to prevent alteration of the contents, the container mouth does not have heat resistance,
In such a container, when the cleaning liquid at 65 ° C. or higher is sprayed, the container mouth may be deformed, which may cause a problem in the sealing property.

されている。There has also been proposed a method of cleaning without providing a plurality of holes in the cap, which is disclosed in Japanese Patent Laid-Open No. 2000-
No. 7096 discloses that a vent slit is formed at a plurality of vertical positions in at least one of a thread portion formed on the outer periphery of a container mouth portion and a thread portion of a cap screwed to the thread portion, and a neck support portion and a cap of the container are disclosed. There is proposed a method of injecting cleaning water toward a gap between the container and the lower end of the container to clean the space between the outer peripheral portion of the container mouth and the inner surface of the cap through the vent slit.

に効果的に流通しないおそれがある。In the above method, since it is necessary to inject the cleaning water at a high pressure in order to effectively flow the cleaning liquid into the cap, the cleaning water that has flowed into the cap has only a vent slit that is continuous in the vertical direction due to its force. There is a risk that it will not pass through and that it will not be spread in the direction between the upper and lower threads, and that the entire outer circumference of the container opening and the entire inner surface of the cap may not be sufficiently washed. Further, in this method, even if the cleaning water is sprayed from the lower end at high pressure, the cleaning water may not effectively flow to the screw thread portion due to the neck support portion of the container.

It is possible to provide a cap.

ことを特徴とするキャップが提供される。According to the present invention, there is provided a cap comprising a top plate portion and a skirt portion having an inner surface provided with a screw portion hanging from a peripheral edge of the top plate portion and engaging with a container mouth portion. The part has a portion in which the screw thread is formed in at least two upper and lower stages, and a cutout is formed in the screw thread so as to form a step difference in the vertical direction, and the cutout and the upper and lower screw threads are formed. A cap is provided, characterized in that the space forms a flow passage for the cleaning liquid.

It is an important feature that the notches form a step in the upper and lower directions, that is, the upper and lower notches do not match in the vertical direction. That is, since the notch provided in the screw part of the conventional cap is continuous in the vertical direction and the cleaning water is sprayed at high pressure, the cleaning water passes only through the notch, and the space between the inner surface of the cap and the outer periphery of the container mouth is increased. It was difficult to efficiently clean the entire area of.

能となるのである。In the present invention, the notch provided in the screw thread forms a step in the vertical direction, and for example, when washing water from below flows through the notch, the one flowing upward and the screw above It is divided into those that hit the mountains and diffuse in the circumferential direction. The wash water that has flowed upward flows downward again from the upper notch, collides with the lower screw thread, changes its flow to the right side, passes through between the upper and lower screw threads, and flows out to another notch again. On the other hand, the cleaning water flowing in the circumferential direction flows through the upper and lower screw threads and flows out to the other notches again, so the flow path of the cleaning water can be lengthened and the inner surface of the cap and the container mouth can be efficiently It is possible to clean the entire area between the outer peripheries.

As shown in FIG. 2, by providing the notches 10a and 10b provided on the upper and lower screw threads 7a and 7b at different positions in the circumferential direction, that is, at positions vertically displaced from each other,
As shown by the arrow A, the washing water flowing from below collides with the lower end 11 of the upper screw thread and efficiently proceeds not only in the upper direction but also in the circumferential direction. Flow downwards again from the top of the lower screw 1
It also hits 2 and flows to the right side, and it becomes possible to clean the entire area between the inner surface of the cap and the outer periphery of the container mouth through the flow passage formed by the notch and the upper and lower screw threads.

ることが可能になる。In the embodiment shown in FIG. 2, the circumferential position of the left end 13 of the notch 10a formed in the upper screw thread is located within the notch 10b formed in the lower screw thread. It is particularly preferable that the right end 14 of the lower cutout 10b is located in the circumferential direction inside the upper cutout 10a, so that the wash water flowing from below collides with the lower end 11 of the upper screw thread. , It is possible to efficiently divide the direction in which the wash water flows by dividing it into the one that flows upward as it is.

が可能となるのである。As another mode, the upper and lower cutouts may have different widths to form a step, and the flow rate through the cutouts may be changed. For example, when the cleaning water flows from below, as shown in FIG. 3, the width of the upper cutout 10a is made smaller than the width of the lower cutout 10b, so that the cleaning water flowing from below is washed. The water does not flow into only the notch 10a, and the washing water hits the lower end 11 of the upper screw thread 7a and is diffused to the left and right, so that the washing can be efficiently performed.

A cap having an E band) is preferable. That is, since the bridge portion that connects the TE bands is also integrally formed without post-processing, the opening between the bridge portions is larger than that cut by a cutter or the like by post-processing, and it is low-temperature cleaning water. Even if the aseptic filling container is used, the entire area between the inner surface of the cap and the outer periphery of the container mouth can be effectively washed.

The present invention is also effective when a notch is made above the cap skirt portion or at the periphery of the top plate portion as in the conventional washing method, and high-temperature washing water is sprayed and made to flow in to perform washing. Even when the wash water flows in from above, the wash water collides with the upper end of the lower screw thread and branches the flow vertically and circumferentially. Of course, it is possible to efficiently clean the entire area between the outer circumferences of the mouths.
