Description

  The present invention relates to a pouring cap attached to the mouth of a container body.

2. Description of the Related Art Conventionally, a pouring cap is known that includes a cap body that is fitted into the mouth of a container body and has a pouring hole, and a lid that opens and closes the pouring hole.
By the way, in recent years, when the extraction cap and the container body are formed of different materials, the container body and the extraction cap are separated and discarded from the viewpoint of recycling.
As means for easily separating the container body and the dispensing cap, for example, as shown in Patent Document 1 below, a plurality of split grooves that open to the lower end edge of the peripheral wall portion of the cap body are provided vertically. A configuration is known in which an arc-shaped strip that surrounds a portion where a plurality of split grooves are formed in the peripheral wall portion of the cap body from the outside in the radial direction is connected via a breakable connecting piece.
In this configuration, the arc-shaped band is picked and pulled, the connecting piece is broken, and the arc-shaped band is separated from the peripheral wall portion of the cap body, so that the groove width of the split groove can be easily expanded. The main body can be easily separated from the mouth of the container body.

Japanese Patent Laid-Open No. 11-189260

  However, in the conventional pouring cap, when the connecting piece is broken, the arc-shaped strip is picked and pulled, so in order to secure the picking margin, it is necessary to increase the vertical width of the arc-shaped strip, In addition, since the arc-shaped belt body surrounds the portion where the plurality of split grooves are formed in the peripheral wall portion of the cap body from the outside in the radial direction, there is a possibility that the pouring cap becomes large as a whole.

  The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a dispensing cap that can be easily separated from a container body and can be prevented from becoming large.

  In order to solve the above problems and achieve such an object, the pouring cap according to the present invention is screwed into the mouth of the container body and has a top tube in which a pouring hole is formed in the top wall. The cap body and the cap body are connected to the cap body via the first connecting piece and are arranged below the cap body, and the rotational movement toward the loose side where the cap body is loosened with respect to the mouth is restricted. A pouring cap comprising a ring-shaped restricting member that is externally inserted into the mouth of the container body, and a lid that opens and closes the pouring hole. The restricting member is provided on the cap body. In addition, the second engaging portion that engages with the first engaging portion from above is connected via the second connecting piece, and the first connecting piece and the second connecting piece are formed to be breakable. And

According to the present invention, when the cap body is strongly rotated together with the lid toward the loose side, the first connecting piece is deformed by the applied force because the restricting member restricts the rotational movement to the loose side. Or it is fractured and the cap body rises with respect to the mouth of the container body together with the lid. At this time, since the second engaging portion of the restricting member is engaged with the first engaging portion of the cap body from above, the upward force is applied to the second connecting piece via the second engaging portion. The second connecting piece is broken. As described above, the second connecting piece may be broken prior to rotating the cap body together with the lid toward the loose side.
After that, the cap body and the lid body are continuously rotated together with the lid to the loose side with respect to the mouth of the container body, so that the cap body and the lid body are separated from the mouth of the container body. By removing the extrapolated regulating member from the mouth, the container body and the extraction cap are separated.
In this way, not only the cap body but also the lid body is rotated with respect to the mouth of the container body, so that the operation fee required for the separation is sufficiently secured even if the overall height of the dispensing cap is kept low. In addition, it is not necessary to provide the pouring cap with an arc-shaped band having a large vertical width in order to secure the picking allowance as in the conventional pouring cap. It can suppress becoming large.
Further, when the dispensing cap is screwed into the mouth portion of the container body filled with the contents, the second engaging portion of the restricting member is engaged with the first engaging portion of the cap body, so that the cap It becomes possible to prevent the relative positions of the main body and the regulating member from becoming unstable, and it is possible to prevent it from becoming difficult to screw the extraction cap onto the mouth of the container body.

  Here, in the peripheral wall portion of the cap body, protective ribs may be provided to protrude from the loosening side to the first connecting piece and the second connecting piece.

  In this case, since the protective rib is provided, when the spout cap is screwed to the mouth portion of the container body filled with the contents using the capping device, the first connecting piece and the second connecting piece are attached. It is possible to prevent the parts of the capping device from hitting and inadvertently breaking these two connecting pieces.

  The lid may be coupled to the cap body via a hinge part and may be formed integrally with the cap body and the regulating member.

In this case, since the lid is connected to the cap body via the hinge portion, when opening the lid and opening the pouring hole, the lid does not have to be separated from the cap body. The operability can be improved.
Moreover, since the lid, the cap body, and the regulating member are integrally formed, the dispensing cap can be easily formed.
