Next, usage modes and operational effects of the present embodiment will be described with reference to the drawings.
The safety cap B of this embodiment starts by combining an inner cap C and an outer cap D made of synthetic resin manufactured by injection molding.
When the outer cap D is put on the inner cap C, the retaining protrusion 25 of the second side peripheral wall 21 of the outer cap D comes into contact with the overhanging portion 16 of the inner cap C. The stop projection 25 can get over the overhanging portion 16, and the overhanging portion 16 is accommodated in the fitting recess 24 of the outer cap D.
At the same time, the distal end portion of the outer cylindrical wall 13 of the inner cap C comes into contact with the holding portion 23 of the outer cap D, and the inner cap C is combined in the outer cap D.

When the safety cap B in which the inner cap C and the outer cap D are combined is placed on the mouth tube portion 4 of the tube container main body A before filling the contents, and the outer cap D is rotated in the closing direction, the inner cap C The ratchet claw 22 of the outer cap D is engaged with the ratchet teeth 14 and the inner cap C is rotated, and the male screw 6 of the tube container body A and the female screw 15 of the inner cap C are screwed together.
When the screwing is finished, the retaining protrusion 25 of the outer cap D comes into contact with the rising wall 5 of the tube container main body A, and the state shown in FIG.
The filling of the contents into the tube container main body A is completed by filling the contents from the filling port (not shown) of the body 1 of the tube container main body A and sealing the filling port.

  In this state, even when the outer cap D is rotated in the opening direction, the ratchet pawl 22 of the outer cap D rides on the ratchet teeth 14 of the inner cap C and the outer cap D rises as shown in FIG. The inner cap C does not rotate and cannot be opened.

  In order to open the plug, as shown in FIG. 4, when a finger is put into the two window portions 26 and the operation portion 28 is pressed, the inward ribs 29 on the inner surface of the operation portion 28 and the outer cap C are removed. Since the outer cap D meshes with the outward ribs 17 on the outer periphery of the cylindrical wall 13, if the outer cap D is rotated in the opening direction, the inner cap C is also rotated, and the screw engagement with the tube container main body A begins to be unwound and continues to rotate as it is. Thus, the safety cap B can be removed from the tube container main body A.

  Rotating the outer cap D while pressing the operation unit 28 requires operation with a fingertip and control of the gripping force, so that it is difficult for a child to operate, and the child can prevent the safety cap B from being opened. .

Next, a second embodiment in which the configuration of the operation portion 28 of the window portion 26 of the outer cap D is changed will be described.
In the following, the same components as those in the first embodiment are denoted by the same reference numerals, and differences will be mainly described.

As shown in FIGS. 5 and 6, in this embodiment, the upper portions of the two window portions 126 of the second side peripheral wall 21 are opened. In addition, an operation unit 128 is erected on the inner side of the window 126 from below the window 126 via a bent portion 127.
A plurality of inward ribs 129 having a saddle-shaped cross section are formed on the inner surface of the operation unit 128 at equal intervals.
Note that a plurality of outward ribs 117 are formed at equal intervals on the outer periphery of the outer cylindrical wall 13 of the inner cap C, and the outward ribs 117 are also on the upper cylindrical wall 13 because the inward ribs 129 are on the upper side. It is formed to the upper part of.

The operational effect of the present embodiment is the same as that of the first embodiment. As shown in FIG. 7, when a finger is put into the window 126 and the operation section 128 is pressed, the operation section 128 faces inward. When the outer cap D meshes with the rib 129 and the outward rib 117 on the outer periphery of the outer cylindrical wall 13 of the inner cap C, and the outer cap D is rotated in the opening direction as it is, the inner cap C is also rotated and screwed with the tube container main body A. The safety cap B can be removed from the tube container main body A by starting to unwind and continuing to rotate.
Other configurations are the same as those of the first embodiment, and the same operational effects are achieved.

In the above-described embodiment, the operation portion is provided continuously from above or below the window portion via the bent portion, but the operation portion is provided continuously from the left or right side via the bent portion. It is also possible.
In this embodiment, two window portions are formed. However, it is also possible to have one window portion. In this case, if the thumb is inserted into the window portion and the operation portion is pressed, the outer cap is removed. Since the orientation rib is firmly engaged with the inward rib of the outer cap, the inner cap can also be rotated by the rotation of the outer cap.

Furthermore, in the first embodiment and the second embodiment, the example of the safety cap B used for the tube container main body A as the container main body is shown. However, the safety cap is used for various containers even if it is not the tube container main body. It can be a safety cap.
In the case of the tube container main body, since the tube container is easily deformed, in order to prevent the cap from being difficult to rotate while being pressed, in this embodiment, a rising wall is provided on the shoulder of the tube container. However, in a container other than the tube container, generally, a rising wall is not required.

  Since the safety cap of the present invention cannot be rotated unless the operation portion provided in the window portion is pressed, it can be prevented from being opened due to a child's mischief, etc. Therefore, it is a widely available safety cap.
