Further, on the tapered outer peripheral surface of the body 31, a plurality of hand-operated protrusions 37 are formed at equal intervals along the axial direction, and are fitted to the pouring tube 10. The protective cap 30 is formed so that it can be easily rotated by hand.

Further, when the protective cap 30 is fitted to the pouring tube 10, the projecting lid portion 33 is opened.
The tip portion is formed in a tapered shape having a smaller diameter toward the mouth portion 153 so as to be easily inserted into the mouth portion 153.

When the protective cap 30 is fitted on the pouring tube 10, the hemispherical projections 17 of the pouring tube 10 are aligned with the slits 36 of the protective cap 30, and the position is protected. When the cap 30 is inserted, the hemispherical projections 17 are guided to be inserted into the slits 36. Next, the operation of the container cap device 1 configured as described above will be described with reference to FIGS.

In a state in which the stopper 19 is not cut and the mouth 153 is closed, the injection tube 10 is welded to a container (not shown) filled with liquid, and then the opening cap 20 is put on the spout tube 10. We attach so that we fit. When the opening cap 20 is fitted to the dispensing tube 10, first, a pair of slits 26 formed in the body 21 of the opening cap 20 are formed.
26 is a hemispherical projection 17. 1 formed on the discharge tube 10.

The tapered concave surface 211 of the opening cap 20 is fitted into 51.

Accordingly, the hemispherical projection 17 is guided along the slit 26, and the shape of the stopper 19 and the stopper engaging portion 23 of the opening cap 20 match, so that the stopper 19 is stopped. The plug engaging portion 23 is engaged. Further, the hooking rib 22 of the opening cap 20 is inserted into the pouring tube 10.
When it is moved toward the hook portion 13 formed on the base portion 11 of the base member, the hook ribs 22 formed over the entire circumference except for the pair of slits 26
By pushing and expanding the projections 131 of the thirteenth, they are further moved and hooked on the hooks 13.
At this time, a pair of locking plate portions 25 formed near the stopper plug engaging portion 23 of the opening cap 20 is
The stopper 19 is firmly supported by the stopper engaging portion 23 of the opening cap 20.

When the liquid in the container is poured out, for example, when a bedridden sick contains a nutrient or a medicinal liquid in the mouth of the bedridden patient, the opening cap 20 is placed on the pouring tube 10. Is rotated in one of the directions. At this time, the opening cap 20 is attached to the hooking rib 22.
Rotates on the protrusion 131 of the hook portion 13, and the hemispherical protrusions 17, 17 rotate the tapered concave surface 211 along the circumferential direction while slightly widening the opening entrance of the tapered concave surface 211 of the opening cap. . Then, the rotation of the opening cap 20 causes the stopper 1 engaged with the stopper engaging portion 23.
Since the nozzle 9 is forcibly rotated with respect to the spouting tube 10, the stopper plug 19 is easily cut off from the connecting portion 191 formed in the shape of a pin, and the mouth 153 is opened.

Subsequently, when the liquid in the container is poured into the mouth of a sick person, the opening cap 20 is removed from the discharge tube 10 and the fitting member such as a catheter or a tube is inserted into the discharge tube 10.
And the liquid is poured out from the mouth 153. The to-be-fitted member does not fall off in its natural state due to the annular protrusion 16 formed on the pouring tube 10 for preventing the coming-off.

The opening cap 20 is detached from the ejection tube 10 by removing the pair of hooks 13 of the ejection tube 10.
Is rotated until it moves to the position of the pair of slits 26 of the opening cap 20 so that the hook 13
Since the tab 13 is detached from the hooking rib 22, the work of detaching the opening cap 20 from the pouring tube 10 can be performed.

Next, the protection cap 30 is mounted on the dispensing cylinder 10. In a state where the opening cap 20 is removed and the protection cap 30 is mounted so as to be fitted on the dispensing cylinder 10, for example, When the container is arranged with the pouring tube 10 facing downward and the bottom arranged above the container is opened, for example, for injecting water, the gripping portion 24 of the opening cap 20 is opened. , Can be arranged so as to bend and grip the bottom of the container that is disposed and opened.

When the container is stored with the liquid remaining in the container, the protective cap 30 is attached so as to be fitted on the pouring tube 10. The protection cap 30 is attached to the ejection tube 10 in the same manner as the opening cap 20 is attached.
After the slit 36 of the protective cap 30 is aligned with 7, the tapered concave surface 311 of the protective cap 30 is mounted so as to be fitted on the tapered surface 151 of the pouring tube 10.

Then, the locking ribs 36 of the protective cap 30 are expanded by pushing the locking portions 13 of the dispensing tube 10 to lock the locking ribs 36 on the projections 131. The projection lid 33 of the protective cap 30 is inserted into the mouth 153 of the pouring cylinder 10 to close the mouth 153 while being fixed integrally with the pouring cylinder 10. Therefore, the liquid in the container is held without leaking to the outside by mounting the protective cap 30.

When the protective cap 30 is to be removed, similarly to the removal of the opening cap 20,
By rotating the pair of hooks 13 until they move to the positions of the pair of slits 36 in the protective cap 30, the hooks 13 come off the hooking ribs 32. An operation of attaching and detaching the cap 30 from the discharge tube 10 can be performed. When the protective cap 30 is rotated, the hand-held projection 37 formed on the body 31 can be prevented from slipping by hand, thereby facilitating the work.

As described above, the container cap device 1 according to the embodiment is firstly constituted by the pouring tube 10 and the opening cap 20, and when the stopper plug 19 is not cut, the opening cap is opened. The cap 20 can be left fitted on the dispensing tube 10, and when the liquid in the container is dispensed, the cap 20 for opening is rotated while being fitted on the dispensing tube 10. As a result, the stopper plug 19 is cut from the discharge tube 10. In this state, the unsealing cap 20 is in a state of being fitted to the dispensing tube 10, so that when actually discharging the liquid in the container, the unsealing cap 20 is removed. Therefore, since the pouring cylinder 10 does not come into direct contact with the hand, it is possible to achieve the effect of being able to hygienically open the spout.

Next, the second container cap device 1 is composed of the spouting tube 10 and the protective cap 30. When the stopper plug 19 is cut and opened, the protective cap 30 is removed. By being fitted to the dispensing cylinder 10, the dispensing cylinder 10 is blocked by the projection lid 33 of the protective cap 30. Therefore, after the liquid is injected from the dispensing cylinder 10 of the container. Even if the liquid is left in the container and stored, the dispensing tube 10 can be protected without directly touching the dispensing tube 10 when the protective cap 30 is attached, so And can maintain a clean state.
