As described above, the pouring cap which also serves as a safety cap which achieves opening by pulling up the pull ring and breaking and removing the removing plate portion has many excellent advantages. At the time of opening, that is, when pulling up the pull ring to break and remove the removing plate along the breaking line, a strong operating force is required at the beginning of the break, and after a part of the breaking line is broken, the removing plate at a stroke When the spout cap is attached to a synthetic resin bottle that seals and stores the content liquid under reduced pressure, the content liquid is opened due to the impact at the time of opening. There was a problem that the inconvenience of spouting from the fresh opening and soiling the surroundings frequently occurred.

[0010] The opening of the bottle is achieved by pulling up the pull ring and breaking and removing the removal plate portion, as in the conventional case. Part facing the shoulder, part facing the shoulder,
It is achieved in the order of the part facing the main body, and when breaking the break line at the tip of the spire first, when breaking the break line at the tip of the shoulder that spreads from the spire to the left and right, When the breaking line portion at the front end of the main body portion is torn in a tearing manner, a large pulling force in a peak shape, that is, a breaking operation force is required.

For this reason, after the break of the break line facing the spire section is completed, it is necessary to increase the operating force again to break the break line facing the shoulder section.
At one tempo, the shoulder break operation will be performed, whereby the break removal processing of the removal plate portion is not achieved at once, but firstly, the spire portion is broken to form a small opening, and as a result, Air is sucked into the bottle to eliminate the reduced pressure inside the bottle, and in this state, the entire removal plate is broken and removed by breaking the main body from the shoulder.

As described above, a small opening is first formed due to the breakage of the spire, and air enters the bottle to eliminate the reduced pressure in the bottle. At this time, since the opening to be opened is small, The intrusion of air into the bottle is achieved in a restricted manner, whereby the elimination of the reduced pressure in the bottle is not achieved rapidly, so that a large rise in the level of the liquid content does not occur, and for example, Even if there is some rise in the liquid surface of the content liquid, since the opening is small, it can not be ejected out of the bottle, so the inconvenience of ejecting the liquid from the opening when opening the bottle is completely prevented. Will do.

Further, the operating force acting on the pull ring is concentrated on the small spire via the leg pieces, and since the direction of operation of the operating force is obliquely forward and upward, the spire has a spire shape. Act more concentrated on the rear end, and the magnitude of the operating force required to initially break the breaking line may be sufficiently smaller than in the past because the degree of concentration is extremely high. It will be.

According to the second aspect of the present invention, since the assembled cylinder, the dispensing cylinder and the lid are integrally formed of the hard-to-break synthetic resin via the hinge, the bottle cap of the dispensing cap is formed. Is strong and stable, and the hinge stably exerts its function against repeated repetitive opening and closing operations of the lid.

Further, since the bottom plate in which the removal plate portion is formed by the breaking line is formed of an easily breakable synthetic resin, the breaking of the breaking line by pulling up the pull ring can be easily achieved. The breaking of the plate portion, that is, the opening of the dispensing cap, can be achieved with a smaller operating force.

In FIG. 5, peaks appear in the order of a spire break start position a, a shoulder break start position b, a main body break start position c, and a break completion position d. When the rupture of the line 9 starts, the rupture operation force decreases. In the main body 11, the rupture operation force decreases at the beginning of the rupture of the rupture line 9, but the rupture operation force increases in the middle, and the rupture completion position is reached. The operation state reaches a peak at d.

Since the present invention has the above-described structure, the following effects can be obtained. According to the first aspect of the present invention, a normal opening operation by pulling up a pull ring causes a small opening due to a breakage of a break line of a spire portion of a removing plate portion forming an opening, and a complete opening by breaking and removing a removing plate portion. Prior to this, the reduced pressure in the bottle can be eliminated without causing ripples in the content liquid, and when the opening is achieved by breaking and removing the removal plate, the content liquid is ejected from the opening just opened. The inconvenience of soiling the surroundings can be reliably prevented.

A certain time interval between the completion of the breaking of the break line of the spire portion of the removing plate portion and the start of breaking of the break line of the shoulder portion is as follows:
As long as the breaking operation force is applied in a normal form, it is inevitably generated according to the spire shape and size of the spire portion and the shape of the shoulder portion, so that no special opening operation form is required, and By performing the unsealing operation, the bottle can be completely opened after the pressure in the bottle is naturally eliminated.
