BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a cap attached to a mouthpiece of a container.

[0002]

2. Description of the Related Art A cap comprising an inner plug having a spout and an upper lid for covering the inner plug and closing the spout is attached to a mouthpiece portion of a container for accommodating a liquid content. In such a cap, the upper lid is detachably attached to the mouthpiece. For this reason, it is necessary to remove the upper lid at the time of use, and to attach the upper lid after use. At this time, there is a problem that it is difficult to remove the upper lid with the hand after taking out the contents such as the hair washes. Further, there is a possibility that the removed upper lid may be lost.

Further, in order to simplify the work of attaching and detaching the upper lid, the inner plug and the upper lid are integrated via a hinge or a hinge, and the inner plug and the upper lid are made freely attachable / detachable. There is a cap. When the cap is used, the upper lid is detached from the inner plug, and the upper lid is rotated about a hinge or hinge. After use, the upper lid is turned in the opposite direction and fitted on the inner lid. According to this cap, the upper lid can be detached with one touch and the upper lid is not lost, but there is a disadvantage that the spout cannot be protruded much to rotate the upper lid. For this reason, the liquid dripping at the pouring outlet adheres to the inner plug and is not only dirty, but also over time, the contents are dried and fixed, and the bacteria are attached and deteriorated.

[0004] As a device for solving these problems, there is disclosed a spout of Japanese Utility Model Application Laid-Open No. 60-195754. The structure of this spout is shown in FIGS. In this spout plug, a coating body 120 that covers the spouting body 100 and the spouting nozzle 110 connected to the container mouth tube is rotatably attached to the spouting body 100. And, while providing the inclined groove 122 which is inclined with respect to the axial direction on the inner peripheral surface of the covering body 120,
A projecting port 121 for projecting the pouring nozzle 110 is provided on the upper surface of the covering body 120. On the other hand, the pouring nozzle 11
A protrusion 111 that engages with the inclined groove 122 is provided on the outer peripheral surface of the “0”. Here, when the coating body 120 is rotated in one direction, the protrusion 121 is positioned above the ejection nozzle 110, and the projection 111 of the ejection nozzle 110 rises along the inclined groove 122 to move the ejection nozzle 110. To raise. As a result, the tip of the pouring nozzle 110 protrudes from the projecting port 121 to above the covering 120. When the cover 120 is rotated in the opposite direction, the projection 111 of the ejection nozzle 110 descends along the inclined groove 122 to lower the ejection nozzle 110. When the pouring nozzle 110 is lowered to the lower end, the position of the content pouring port of the pouring nozzle 110 and the projecting port 122 of the cover 120 are shifted, and the pouring of the content is closed.

[0005] Also, the pouring nozzle 110 and the pouring main body 100
On the sliding surface between the outlet port 101 and the outlet port 101 for guiding the contents to the outside, the discharging nozzle 110 is provided with a content inlet port 112 at a position coinciding with the outlet port 101 when ascending. I have. Thereby, the discharge nozzle 110
When the outlet rises, the outlet 101 and the content introduction port 112 coincide with each other, and the inside of the ejection main body 100 and the inside of the ejection nozzle 110 communicate with each other, and the content is discharged from the ejection main body 110 to the outlet 101 and the content introduction port. It is guided to the discharge nozzle 110 via 112 and further discharged from the content discharge port of the discharge nozzle 110.
When the pouring nozzle 110 is lowered, the position of the outlet 101 and the position of the content inlet 112 are shifted, and the outlet 101 and the content inlet 112 are closed.

According to the present invention, the time required for attaching and detaching the lid can be simplified, and since the nozzle is projected above the coating by rotating the coating, contamination of the cap due to dripping can be prevented. There is an advantage.

[0007]

However, in the above-mentioned invention, there is a possibility that the contents may remain at the bottom of the pouring nozzle and deteriorate. In addition, a content introduction port and a discharge port are provided on the sliding surface of the nozzle and the discharging main body, respectively, and when the liquid is stored in the container, the inner solution is filled between the discharging nozzle and the discharging main body. It is easy to enter, and if left unattended, there is a risk that the contents will stick and the spout nozzle and the spout body will adhere. On the other hand, the frictional resistance generated between the ejection nozzle and the ejection main body increases, so that a large force is required for rotating the coating, and the operability is deteriorated.

In view of the foregoing, the present invention has been made in view of the above-mentioned problems, and provides a sanitary cap by preventing the remaining contents and liquid dripping. The task is to provide.

[0009]

The present invention has been made as follows in order to solve the above-mentioned problems. That is, the cap of the present invention has a cap main body in which a pipe-shaped nozzle that is screwed to the mouthpiece portion of the container and protrudes upward from the mouthpiece portion, and a top plate that covers the cap body, The top plate is provided with a through hole having a diameter larger than that of the nozzle, and a lid provided to be vertically movable in the cap main body for raising and lowering the nozzle, and one opening of the through hole is opened and closed. A first valve body and a second valve body for opening and closing the other opening;
The first valve body and the second valve body are pushed open when the nozzle is relatively raised with respect to the cap body, lowered with respect to the cap body, and closed when the nozzle is immersed in the lid body. is there.

The first valve body is provided with a thin plate-like elastic material so as to cover an upper opening of the through-hole, and a plurality of slits are radially provided in the elastic material with a center at a penetrating position of the nozzle. preferable. The second valve element only needs to have a shape and a size that prevent the through hole.

The nozzle is located inside the lid when not in use, and is shut off from the outside by a first valve body and a second valve body. The nozzle need not be formed integrally with the cap body as long as the nozzle can discharge the contents. Also,
In some applications, it is more preferable to cut off the tip of the nozzle diagonally in order to easily pour out the contents and prevent dripping. Further, as the material used for the nozzle, a resin-based material of an elastic material whose corrosion resistance and safety for living bodies are sufficiently confirmed is most preferable.

As a mechanism for moving the lid up and down, a guide groove whose inclination is perpendicular to the outer peripheral wall of the cap body and the inner peripheral wall of the lid is formed at right angles to the circumferential direction. At least one vertical movement mechanism for the lid and the nozzle is formed as a pair including a movable fitting protrusion. In this case, the guide groove moves up and down with the fitting protrusion as a base point. The height from the lower end to the upper end of the guide groove is such that when the lid is rotated and the fitting protrusion is located at the lower end of the right-angle groove, the upper end of the nozzle is housed in the lid and fits into the upper end of the guide groove. When the projection is located, the upper end of the nozzle has a height protruding upward from the through hole of the lid. Further, if at least one locking projection for fixing the fitting projection is provided at the upper and lower ends of the guide groove, the operability is further stabilized.

[0013]

According to the cap of the present invention, when the lid is lowered, the upper end of the nozzle housed in the lid comes into contact with the second valve provided at the lower opening of the through hole. When the lid is further lowered, the upper end of the nozzle pushes and opens the second valve body, and similarly comes into contact with the first valve body provided at the upper opening of the through hole. By further lowering the lid, the upper end of the nozzle pushes the first valve body open and projects above the lid. At this time, the user pours out the contents in the container.

When the lid is raised after the contents are poured out, the upper end of the nozzle is housed in the lid, and the first and second valve bodies close the through holes. Here, the top plate portion of the lid is made elliptical, and the through hole is provided at an eccentric position, that is, provided near the periphery of the top plate, so that the nozzle is close to the pouring position when the contents are poured out by hand or the like. This facilitates pouring.

In the guide groove, a locking projection for fixing the fitting projection to the upper end may be provided in front of the upper end. Thus, unnecessary rotation of the lid can be prevented. Also,
As a means for vertically moving the lid, a fitting projection is formed on the cap body, and a guide groove is formed on the lid, and when the user rotates the lid in one direction, the fitting projection of the cap body becomes the guide groove. Rise along. The lid is lowered accordingly.
When the lid is lowered, the upper end of the nozzle comes into contact with the second valve, and when the lid is further lowered, the upper end of the nozzle pushes the second valve to open and comes into contact with the first valve. . When the lid is further lowered, the upper end of the nozzle pushes open the first valve body and projects upward. At this time, the second valve element is bent along the inner wall of the through hole, overlaps the first valve element, and projects upward from the first valve element. In this state, the user discharges the contents.

After the contents are poured out, the user rotates the lid in the opposite direction. As a result, the fitting projection of the lid rises along the guide groove of the cap body, and the lid rises accordingly. When the fitting projection is located at the upper end of the guide groove, the upper end of the nozzle is housed between the lid and the cap body, and is provided by first and second valve bodies provided at the upper and lower openings of the through hole. The through hole is closed.

At this time, the nozzle 10a is housed in the lid 2, and the first valve body 20b and the second valve body 20e of the through hole 20a are in a closed state.

In the process of lowering the lid 20, the nozzle 10
The upper end of the nozzle a contacts the valve 20f, and when the lid 20 is further pushed down, the upper end of the nozzle 10a pushes and opens the second valve 20e, and then contacts the first valve 20b to push the valve 20b. It opens and projects above the lid 20 (see FIGS. 5 and 6). At this time, the second valve element 20e is transmitted along the inner wall of the through hole, overlaps the first valve element 20b, and projects upward from the first valve element 20b. The first valve body and the second valve body near the entrance of the through hole
When the valve bodies overlap, these serve as stoppers, and operability can be improved. In this state, the user pours out the contents of the container.

After the contents are poured out, the user pushes the lid 20 upward. As a result, the lid 20 rises along the guide groove 10b. When the upper end of the nozzle 10a is lowered to a position lower than the top plate 20d of the lid 20 in the process of raising the lid 20, the first valve body 20b closes the through hole 20a.
