  The present invention relates to a pouring cap that is plugged into the mouth of a container, and relates to a technique for facilitating the separation and recovery thereof.

The conventional pouring cap has a main body that has a spout and is plugged into the mouth of the container, and a base for separating the main body from the mouth of the container, and is arranged around the main body with a space therebetween. The opening / closing lid connected to the outer cylinder portion via a hinge is used as an operation piece, causing the main body to be pulled away from the mouth of the container, and separating and collecting the dispensing cap. There are things that can be easily adjusted (see, for example, Patent Document 1).
JP 2003-246338 A

  However, the conventional pouring cap for the purpose of such separation and recovery has an annular groove formed at the lower end thereof, and a projection that engages the outside of the mouth of the container is provided inside the annular groove to When used and plugged into the mouth of the container, there are the following problems.

  That is, the conventional pouring cap has an annular groove at the lower end where the mouth of the container meets, and a projection that engages the outside of the mouth of the container is provided inside the annular groove. At this time, the external shape of the outer cylinder part may be locally distorted along the circumferential direction.

  Although such distortion does not affect the performance of the dispensing cap at all, it is preferable to suppress the difference appearing in the appearance shape as much as possible in consideration of the difference in the willingness to purchase depending on the appearance.

  Therefore, as a result of testing and research, the inventor of the present application has found that such local distortion and deformation are caused by the connecting piece between the main body and the outer cylindrical portion, compared to the fact that the rigidity of the outer cylindrical portion is higher in the connecting piece portion. It has been found that this is due to the low gap in the partitioned gap.

  The problem to be solved by the present invention is to cause local distortion and deformation in the outer cylinder portion when the extraction cap intended for separation and recovery is plugged into the mouth portion of the container. The purpose of this is to provide a pour-out cap that is attractive and has excellent customer suction by suppressing local distortion and deformation at the outer cylinder.

  The pouring cap according to the present invention has a main body having a pouring outlet for pouring out the contents of the container and plugged into the mouth of the container, and a connecting base for separating the main body from the mouth of the container. An outer cylinder part arranged around the main body with an interval, and an opening / closing lid that is connected to the outer cylinder part via a hinge to cause the separation, and the main body and the outer cylinder part are arranged in the circumferential direction. In the pouring cap connected by a plurality of breakable connecting pieces arranged at intervals along the gap, at least of the gaps among the plurality of gaps partitioned by the connecting pieces between the main body and the outer cylinder part A thin portion for maintaining the distance between the main body and the outer tube portion is provided at one place.

  The thin-walled portion according to the present invention only needs to be capable of being broken together with the connecting piece when the main body is pulled away from the mouth portion of the container through the outer cylinder portion using the opening / closing lid as the operation piece.

  As a specific example, the thickness of the thin portion is in the range of 0.05 to 0.2 mm, preferably 0.1 mm or less. Moreover, although it is preferable that the thickness of a thin part is equal, it is not limited to this.

  In the present invention, the thin portion can be provided so as to close the gap. Moreover, you may provide a thin part so that a clearance gap may be left between connection pieces.

  Further, in the case where the occurrence of local distortion or deformation can be estimated in consideration of the shape of the outer cylinder portion, etc., the thin-walled portion may be provided at the corresponding portion of the plurality of gaps. According to the above, it is preferable to provide in all the gaps except for the gaps arranged immediately below the hinges.

  According to the present invention, among the plurality of gaps partitioned by the connecting piece between the main body and the outer cylinder portion, at least one portion of the gap is a thin wall portion for maintaining the interval between the main body and the outer cylinder portion. Since the rigidity of the outer cylinder part is almost uniform regardless of the part where the connecting piece exists or the part where the gap exists, when plugging the dispensing cap into the mouth of the container, Local distortion and deformation occurring in the outer cylinder portion can be suppressed.

  Therefore, according to the present invention, it is possible to provide a pouring cap that has little local distortion and deformation at the outer cylinder portion and has a good customer suction force.

  Further, if the thin portion according to the present invention is provided so as to close a gap formed between the connecting pieces between the main body and the outer cylindrical portion, local distortion and deformation in the outer cylindrical portion are suppressed. It is more effective against.

  In addition, if the thin wall portion according to the present invention is provided so as to leave a gap between the connecting pieces, the thin wall portion is easily broken, so that while maintaining the operability at the time of separation and recovery of the pouring cap, Local distortion and deformation occurring in the outer cylinder portion can be suppressed. In addition, in this case, while maintaining the water draining function originally held in the gap defined by the connecting piece between the main body and the outer cylinder part in the gap between the connecting piece and the thin part, Local distortion and deformation that occur can be suppressed.

  Furthermore, if the thin portion according to the present invention is provided in all the remaining portions except for one place among the plurality of gaps, the thin portion is originally carried by the gap defined by the connecting piece between the main body and the outer cylinder portion. While maintaining the draining function that has been performed in the gap where the thin-walled portion 8 is not provided, local distortion and deformation occurring in the outer peripheral portion can be efficiently suppressed. In addition, when the main body is pulled away from the mouth of the container, it is easy to start breaking the connecting piece, so that the local distortion or deformation that occurs in the outer cylinder portion is maintained while maintaining the operability at the time of separating and collecting the extraction cap. Can be suppressed.
