Description

The present invention relates to a one-touch nozzle cap capable of securely covering and sealing a nozzle even in a tube container having a high nozzle tip such as a tube for accommodating cosmetics and the like.

Conventionally, a container in which a squeezeable container is filled with mucus and squeezed out from a nozzle has been used. Screw-type caps and one-touch caps are used as caps for covering this type of container.

Generally, a screw cap is used for a squeezeable container such as a tube filled with cosmetics, which has a high nozzle at the tip of the container. That is, when filling a tube container with cosmetics containing fragrances, etc., the tip of the nozzle should be raised in order to prevent the fragrances, etc. from diverging to the outside and to prevent outside air from entering the tube container. A screw-type cap having a protrusion to be set and inserted into the opening of this nozzle is used (see Patent Document 1).

In addition, when extracting cosmetics, a certain amount may be squeezed out in the form of drops. In this case, a discharge hole for discharging droplets is formed at the tip of a thin and long nozzle. Then, in order to stop the discharge hole, a screw type cap provided with a stopper rod to be inserted into the discharge hole is used (see Patent Document 2).

On the other hand, in the tube container for accommodating toothpaste and the like, a one-touch cap that is easy to use with one hand is used (see Patent Document 3). This cap is connected to a hinge and can cover the opening with one touch, and is often used for a tube container for accommodating toothpaste and the like, which are often operated with one hand.

Japanese Unexamined Patent Publication No. 11-11501 Special Table 2017-504379 Japanese Unexamined Patent Publication No. 2011-84288

The screw type cap requires the use of both hands when opening and closing the cap, and the one-touch cap can be used with one hand. Therefore, if a one-touch cap is also used for the tube container for storing cosmetics, the cosmetics can be used with one hand.

However, the nozzle of a tube container filled with cosmetics or the like needs a protrusion that is inserted into the tip of the nozzle to enhance the sealing force. Therefore, if this protrusion is provided on the one-touch cap, the cap may not be closed securely.

That is, in the basic configuration of the conventional one-touch cap 10, a ring-shaped fitting portion 15 that fits on the outer circumference of the tip opening 12A of the nozzle 12 is provided inside the lid 14, and the lid 14 is provided with the hinge 13 as a fulcrum. (See FIG. 6). Then, when the lid 14 is in a substantially horizontal position, the fitting portion 15 is fitted to the outer periphery of the nozzle 12 (see FIG. 9).

However, in a nozzle 12 having a high tip such as a cosmetic container, the fitting portion 15 abuts on the tip of the nozzle 12 and interferes with the lid 14 in an inclined state (see FIG. 7). Further, even if the fitting portion 15 that interferes is removed, in that case, the protrusion 16 abuts on the tip portion of the nozzle 12 and interferes (see FIG. 8).

Therefore, when the conventional one-touch cap 10 is provided with the protrusion 16 to be inserted into the opening of the nozzle 12, the fitting portion 15 and the protrusion 16 interfere with the nozzle 12, so that these interference portions are deformed and damaged. It turned out that it would end up. If the protrusion 16 or the tip opening 12A of the nozzle 12 is deformed or damaged in this way, the nozzle 12 cannot be sealed, and not only the fragrance or the like is emitted to the outside, but also the contents may leak out. (See FIG. 8).

Further, when the protrusion 16 is formed on the conventional one-touch cap 10, the protrusion 16 is inserted into the tip of the nozzle 12, and the ring-shaped fitting portion 15 is fitted to the outer periphery of the tip of the nozzle 12. Therefore, air and contents are likely to collect between the ring-shaped fitting portion 15 and the protrusion 16. As a result, the air and the contents act as cushions to prevent the lid 14 from being completely closed, and a gap 4A is formed between the lid 14 and the connecting portion 11 (see FIG. 9).

Moreover, when the protrusion 16 is inserted into the tip of the nozzle 12, the contents remaining between the protrusion 16 and the fitting portion 15 are scattered together with air from the gap of the fitting portion 15 into the lid 14 and around the nozzle 12. It was also found that it would end up (see Fig. 9). In particular, the tube container P or the like filled with cosmetics may adversely affect the product image if even a small amount of the contents are scattered around the nozzle 12.

Therefore, the present invention has been created to solve the above-mentioned problems, and an object of the present invention is to provide a one-touch nozzle cap capable of securely covering a tube container having a high nozzle tip and sealing the nozzle. is there.

In order to solve the above-mentioned problems, the first means of the present invention is a connecting portion 1 connected to the mouth portion P1 of the tube container P, a nozzle 2 protruding from the connecting portion 1 in the tip direction, and a side surface of the connecting portion 1. A hinge portion 3 that is swingably provided on the surface, a lid portion 4 that is swingably provided on the hinge portion 3 and covers the nozzle 2, and a nozzle formed on the inner surface of the lid portion 4 at the time of lidging. A one-touch nozzle cap provided with a fitting portion 5 that fits on the outside of the tip of 2, and an air discharge port 5A that discharges air inside the fitting portion 5 is formed in the fitting portion 5, and a nozzle is provided. The protrusion 6 that is inserted into the tip opening 2A of 2 and seals the opening 2A, and the introduction rib 7 that slides into the outer surface of the nozzle 2 on the opposite side of the hinge portion 3 at the peripheral edge of the tip of the nozzle 2. It is formed on the inner surface of the lid portion 4, and when the lid portion 4 is covered, the protrusion 6 is in sliding contact with the tip of the nozzle 2, and the introduction rib 7 is in sliding contact with the tip of the nozzle 2. ..

In the second means, when the lid portion 4 is covered, the shatterproof cover 8 surrounding the fitting portion 5 is projected inside the lid portion 4.

In the third means, a taper 7A is formed on the inner surface of the tip opening 2A of the introduction rib 7, the introduction rib 7 is in sliding contact with the taper 7A, and the taper 2B at the same angle as the taper is the introduction rib 7. The taper 2B is formed on the sliding contact surface of the nozzle 2 so as to be in sliding contact with the tip end portion of the nozzle 2.

The fitting portion 5 of the fourth means arranges a pair of fitting portions 5 at positions sandwiching both sides of the nozzle 2, and forms the air discharge port 5A between these fitting portions 5. It was done.

The hinge portion 3 of the fifth means is formed at the height of the base end portion of the nozzle 2.

As in claim 1 of the present invention, when the lid portion 4 is covered, the introduction rib 7 slides in contact with the tip portion of the nozzle 2 and moves, and the protrusion 6 is introduced into the tip opening portion 2A of the nozzle 2. As a result, the fitting portion 5 can be fitted while the tip opening 2A of the nozzle 2 is sealed by the protrusion 6 without deforming or damaging the protrusion or the opening. As a result, in the structure of the one-touch cap, even a tube container having a high nozzle can be reliably covered, and the tube container for storing cosmetics and the like can be opened and closed with one hand.

Moreover, since the fitting portion 5 is formed with an air discharge port 5A for discharging the air inside the fitting portion 5, the lid portion 4 can be easily opened and closed. Further, since air is not accumulated between the fitting portion 5 and the protrusion 6 and is not compressed, the contents remaining between the fitting portion 5 and the protrusion 6 are widely scattered together with the compressed air. Can be prevented.

As in claim 2, since the shatterproof cover 8 surrounding the fitting portion 5 is projected inside the lid portion 4, the residue is slightly scattered between the fitting portion 5 and the protrusion 6. Even so, the shatterproof cover 8 can reliably capture the scattered matter. Therefore, there is no risk that the scattered contents will stain the area around the nozzle and spoil the product image.

As in claim 3, a taper 7A is formed on the inner surface of the tip opening 2A of the introduction rib 7, the introduction rib 7 is in sliding contact with the taper 7A, and the taper 2B at the same angle as the taper is the introduction rib. By forming the taper 2B on the sliding contact surface of No. 7 so that the taper 2B is in sliding contact with the tip of the nozzle 2, the protrusion 6 can be formed without deforming the tip of the nozzle 2 even in a tube container having a higher nozzle. It can be reliably introduced into the tip opening 2A.

As in claim 4, the fitting portion 5 arranges a pair of fitting portions 5 at positions where both sides of the nozzle 2 are sandwiched, and the air discharge port 5A is provided between these fitting portions 5. Therefore, air is no longer accumulated and compressed between the fitting portion 5 and the protrusion 6 at the time of lidging. As a result, the lid portion 4 can be easily covered, and even if the contents remain at the tip of the nozzle 2, the amount of the contents scattered at the time of lidging is significantly reduced.

By forming the hinge portion 3 at the height of the base end portion of the nozzle 2 as in claim 5, the configuration is similar to that of the conventional one-touch nozzle cap. As a result, it is not necessary to make a conspicuous change in the position such as raising the position of the hinge.

As described above, according to the present invention, even a tube container having a high nozzle tip for storing cosmetics and the like can be surely covered with a one-touch cap, and various other industrially beneficial effects can be obtained.

Hereinafter, embodiments of the present invention will be described. The cap of the present invention relates to a one-touch nozzle cap that can be used especially for a tube container for filling cosmetics and the like.

This one-touch nozzle cap is a cap that can be opened and closed with one hand, and has the following configuration. That is, a connecting portion 1 connected to the mouth portion P1 of the tube container P, a nozzle 2 projecting from the connecting portion 1 in the tip direction, a hinge portion 3 oscillatingly provided on the side surface of the connecting portion 1, and the like. It is a cap provided with a lid portion 4 oscillatingly provided by the hinge portion 3 and a fitting portion 5 formed on the inner side surface of the lid portion 4 and fitted to the outside of the tip of the nozzle 2 (FIG. 1). , See FIG. 2). Further, in the present invention, the tube container refers to a container that can be squeezed in general, and is a container that includes a bottle having a squeeze property in addition to the tube.

As the tube container for accommodating cosmetics and the like, the tube container P having a relatively high nozzle 2 height is mainly used. For example, a tube container P in which the hinge portion 3 is formed at the height of the base end portion of the nozzle 2 and the ratio of the height of the tip end of the nozzle 2 to the body diameter of the base end portion of the nozzle 2 is about 2: 1. The cap of the present invention can reliably cover such a tube container P having a relatively high nozzle 2.

The main configuration of the present invention is to form an air discharge port 5A in the fitting portion 5 of the one-touch nozzle cap, and as a new configuration, a protrusion 6 for sealing the tip opening 2A of the nozzle 2 and a tip of the nozzle 2. It is configured to include an introduction rib 7 that is in sliding contact with the peripheral edge of the portion.

The air discharge port 5A is a portion formed so as to open a part of the fitting portion 5 to discharge the air inside the fitting portion 5. That is, the fitting portion formed on the conventional one-touch nozzle cap has a ring shape that fits on the outer periphery of the tip of the nozzle 2, but in the present invention, the air discharge port 5A is formed in the fitting portion 5. It is provided so that the air accumulated inside the fitting portion 5 is not compressed.

In the illustrated example, a pair of fitting portions 5 are arranged at positions where both sides of the nozzle 2 are sandwiched, and an air discharge port 5A is formed between these fitting portions 5. If air is discharged from the air discharge port 5A when the cap is closed, the air does not collect inside the fitting portion 5, so that even if residue is attached around the tip of the nozzle 2, it is compressed. It prevents it from spreading widely with the air.

Further, by projecting the anti-scattering cover surrounding the fitting portion 5 inside the lid portion 4, even if a small amount of scattered matter is generated when the lid portion 4 is crimped, the scattered matter can be reliably captured. ..

The protrusion 6 is a member to be inserted into the tip opening 2A of the nozzle 2 and seals the opening 2A. The protrusion 6 is formed on the inner surface of the lid 4, and moves while sliding in contact with the tip of the nozzle 2 when the lid 4 is applied to seal the tip opening 2A. In this case, if the protrusion 6 strongly hits the tip of the nozzle 2, the protrusion 6 and the nozzle 2 will be damaged. Therefore, in order to reduce the pressure at the time of sliding contact, the introduction rib 7 is arranged.

The introduction rib 7 is also formed on the inner surface of the lid portion 4, and when the above-mentioned protrusion 6 is in sliding contact with the tip of the nozzle 2, the introduction rib 7 is also in sliding contact with the tip of the nozzle 2. , It has the effect of reducing the contact pressure applied to the nozzle 2 from the protrusion 6. Therefore, the position of the introduction rib 7 is arranged so as to be in sliding contact with the outer surface of the nozzle 2 on the opposite side of the hinge portion 3 at the peripheral edge of the tip portion.

When covering the lid portion 4, first, the protrusion 6 is in sliding contact with the tip of the nozzle 2, and at the same time, the introduction rib 7 is in sliding contact with the outer surface of the tip opening 2A of the nozzle 2. Further, when the lid portion 4 is closed, the protrusion portion 6 is smoothly introduced into the tip opening portion 2A while reducing the contact pressure applied from the protrusion portion 6 to the nozzle 2.

In the illustrated example, a taper 7A is formed on the sliding contact surface of the introduction rib 7, and the introduction rib 7 is in sliding contact with the tip of the nozzle 2 along the taper 7A. On the other hand, a taper 2B is also formed at the tip opening 2A of the nozzle 2. By setting the angles of both the taper 7A and the taper 2B to the same angle, the protrusion 6 can be introduced even in a tube container having a higher nozzle.

Although the present invention has been described particularly based on the tube container P having a higher nozzle, it can also be used for a tube container P having a lower nozzle in which a conventional one-touch nozzle cap is used. Further, the configuration of the present invention is not limited to the illustrated example, and each configuration of the fitting portion 5, the protrusion 6, the introduction rib 7, the shatterproof cover 8, etc. is arbitrary as long as the gist of the present invention is not changed. Can be changed to.
