Description

  The present invention relates to a cap that is attached and fixed to the upper end portion of an aerosol container. More specifically, the cap has a push button formed integrally therewith, and an injection nozzle provided in the push button has a nozzle hole. It is related with what was formed integrally.

Examples of the conventional cap with a push button include those described in the following patent documents.
The aerosol cap described in Patent Document 1 is to provide a one-touch type aerosol cap that can reliably prevent inadvertent depression of a push button, and its main configuration is:
A cap body having a crown part and a pair of side walls to be placed on the aerosol can, a push button having a nozzle part in which an injection port is formed, and a collar part provided between the side walls.

In the push button in the aerosol cap, the injection port at the tip of the nozzle portion is integrally formed.
That is, in the conventional injection nozzle, it was formed by fitting a nozzle tip or nozzle piece of an appropriate form to the tip of the nozzle. However, the injection nozzle portion described in Patent Document 1 is a nozzle-integrated type. And can be formed integrally with the button, and at the same time, a desired nozzle can be formed.
Similarly, the aerosol cap described in Patent Document 2 is the same as that described in Patent Document 1.

In the injection nozzle part (injection port part) described in these patent documents, although it shape | molds using the metal mold | die illustrated in FIG. It has a needle-like portion 42M that forms an outflow channel, and this needle-like portion needs to be very thin (having a diameter of about 0.4 mm to about 1.0 mm). Therefore, the length of the outflow passage and the length of the injection port in the longitudinal direction is limited to a short one as appropriate.
This is because in order to lengthen the injection port part, it is necessary to form the needle-shaped part of the mold long, and if it is formed so long, the needle-shaped part is bent or bent, etc. It was impossible to manufacture because it was not molded properly.

On the other hand, FIG. 9 shows another conventional spray nozzle portion, in which (A) is a partially cutaway perspective view, and (B) is a central longitudinal sectional view, and the length of the spray nozzle portion. It shows a long thing.
As can be seen from this figure, in order to form the long injection nozzle portion N in the push-down button B, the inner diameter of the outflow path P of the injection nozzle portion N needs to be larger than a predetermined size.
This is because the length of the flow path of the outflow path P becomes longer, the outer diameter of the mold for molding the outflow path P must be appropriately increased, and the strength must be maintained. The inner diameter of the outflow passage P of the part N had to be appropriately increased.
Therefore, in the case of this conventional injection nozzle, the injection piece F and the injection tip are formed separately at the injection nozzle, and the injection nozzle piece F and the like are fitted to the tip of the injection nozzle portion N. It is.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 illustrates a first embodiment of a button cap integrated with a nozzle according to the present invention, in which (A) is a half cutaway perspective view and (B) is a central longitudinal sectional view.

The button cap 1 is attached and fixed to an upper end portion of an aerosol container (not shown), and includes a cap body 10 and a push button 20.
The cap body 10 includes a crown portion 11 that is crowned on the upper end portion of the aerosol container, and a pair of side wall portions 12 and 12 that extend upward from the crown portion 11.

A push button 20 is disposed between the side walls 12 and 12.
A connection hinge portion 30 is provided to connect the front lower end portion of the push button 20 and the crown portion 11, and the push button 20 can be moved up and down by the connection hinge portion 30.

More specifically, the connection hinge portion 30 has a substantially L shape in a side view (substantially L shape rotated 90 degrees to the right), and one end thereof is connected to the crown portion 11 of the cap body 10, The other end is connected to the front lower end of the push button 20.
On both sides of the bent portion 30f of the connection hinge portion 30, there are provided connection portions for connecting the connection hinge portion 30 and both side wall portions 12 of the cap body 10, and these connection portions can be easily shredded by hand. It can be cut to such an extent that it can be cut.

With such a configuration, the cap main body 10 can be detached from the aerosol container, the connection portion can be shredded, and the push button 20 can be moved forward in the injection direction.
As will be described later, this operation is performed to remove residual gas.

The configuration of the push button 20 is as follows.
The push button 20 has a nozzle portion 23 provided with a first outflow passage 21 extending vertically upward connected to the valve stem of the aerosol container and a second outflow passage 22 substantially orthogonal to the first outflow passage 21. It is integrally molded.

The tip of the nozzle part 23 forms a nozzle hole 24, that is, the present invention is characterized in that the nozzle hole 24 is formed integrally with the nozzle part 23.
Further, since the nozzle portion 23 is formed integrally with the nozzle hole 24, the inner diameter of the second outflow passage 22 is very small, approximately 0.4 mm to 1.0 mm.
Therefore, the outer diameter of the nozzle portion 23 is also about 2.5 mm to 4.0 mm, and has a very thin needle shape.

Since the outer diameter of the nozzle portion 23 is small, a plate-like reinforcing member 25 is provided below the nozzle portion 23 in the present invention for reinforcement.
The plate-like reinforcing member 25 is a mode in which the upper end thereof supports the nozzle portion 23, the lower end thereof is connected to the connection hinge portion 30, and the nozzle portion 23 is supported from below.

The push button 20 is further provided with a residual gas venting stem mounting portion 28 behind the first outflow passage 21.
The contact portion 28t of the residual gas venting stem mounting portion 28 with the valve stem is provided at a position lower than the contact position of the contact portion 21t of the first outflow passage 21 with the valve stem.
As a result, when the residual gas venting stem mounting portion 28 is mounted on the valve stem of the aerosol container, the valve stem can be maintained in a depressed state, and the state in which residual gas is discharged can be maintained.

  More specifically, when the use of the contents in the aerosol container is finished, the cap body 10 is removed from the container, and the push button 20 of the cap body 10 is pulled forward through the connecting portions on both sides of the connection hinge 30. The push button 20 is fixed between the side wall portions 12 of the cap body 10 according to the configuration described later, and the cap body 10 is then attached to the container, whereby the residual gas venting stem of the push button 20 is obtained. The mounting portion 28 is mounted on the stem of the container so that the residual gas can be removed.

  The configuration in which the push button 20 is fixed between the side wall portions 12 and 12 of the cap body 10 will be described later in the second embodiment. It is realized by fitting with the provided fitting recess, and on the other hand, the rear end corners on both sides of the push-down button 20 are engaged with the engaging projections provided on the both side walls 12, 12.

  That is, when the cap body 10 is removed from the container and the push button 20 is moved forward, the front end corners on both sides of the push button 20 are fitted into the fitting recesses on both side walls, and the rear end corners on both sides of the push button 20 The pressing portion 20 is sandwiched and fixed between the side wall portions 12 and 12 by engaging the engaging projections of the side wall portions. After that, by attaching the cap body 10 to the container again, the stem mounting portion 28 for the degassing of the push-down button 20 is mounted on the stem of the container, and the stem is maintained in the depressed state. It can be maintained.

Next, a second embodiment of the present invention will be described with reference to FIGS.
FIGS. 2A and 2B illustrate a second embodiment of the button cap integrated with a nozzle according to the present invention, in which FIG. 2A is a perspective view and FIG. 2B is a partially cutaway perspective view.
FIG. 3A is a half cutaway perspective view of the second embodiment, and FIG. 3B is a central longitudinal sectional view thereof.
FIG. 4A is a central horizontal sectional view of the nozzle portion of the second embodiment, and FIG. 4B is a central vertical sectional view of the nozzle portion.
In addition, the code | symbol in a figure has provided the same code | symbol to the same structural member as the said 1st Embodiment. The same applies to third and fourth embodiments described later.

In the second embodiment, the part different from the first embodiment is that there is no plate-like reinforcing member provided in the first embodiment. In the second embodiment, the nozzle member is used as the reinforcing member. A cylindrical reinforcing cylinder 26 is provided so as to surround 23.
Other configurations are the same as those in the first embodiment.

The reinforcing cylinder 26 in the second embodiment does not surround the entire nozzle portion 23, but the portion of the nozzle hole 24 at the tip thereof protrudes from the tip of the reinforcing cylinder 26 to the outside. Forming.
As will be described later, a notch is provided in the longitudinal direction of the nozzle hole 24 at the tip of the nozzle portion 23, and the contents sprayed by this notch can obtain a spray pattern that is wide in the vertical direction.
This configuration is the same as in the first embodiment.

As described above, the reason why the nozzle hole 23 of the nozzle portion 23 protrudes outward from the tip end portion of the reinforcing cylinder 26 is to prevent the wide injection pattern from being hindered.
In other words, when the reinforcing cylinder 26 covers all of the tip of the nozzle portion 23, the tip of the reinforcing cylinder 26 becomes an obstacle to the wide spray pattern of the contents.

The reinforcing cylinder 26 can be integrally formed with the push button and the nozzle portion.
By referring to the cross-sectional view of FIG. 4, the form of the nozzle part according to the present invention can be seen well, but the nozzle part 23 according to the second embodiment (the nozzle part of the first embodiment is the same). .) Is provided with a second outflow path 22 in a direction orthogonal to the first outflow path 21, and the second outflow path 22 reaches the nozzle hole 24 as it is, and the inner diameter thereof is also the same.

That is, the second outflow passage 22 forms the nozzle hole 24 as it is. That is, the inner diameter of the second outflow path is small enough to form the nozzle hole 24.
Conventionally, a nozzle portion having such a small inner diameter and a long flow path could not be formed as appropriate, but this can be realized in the present invention and has such a needle-like form. The nozzle part 23 was completed.

  The injection pattern can be widened only by providing the cutout 24k in the diameter direction at the portion of the nozzle hole 24. That is, if the cutout 24k is provided in the vertical vertical direction, the injection pattern can be widened in the vertical direction. If a spray pattern is obtained and a cut is provided in the horizontal direction, a wide spray pattern in the horizontal direction can be obtained.

In the second embodiment, as shown in FIG. 4A, the cuts 24k are formed so as to be gradually narrower from the tip of the nozzle hole 24 toward the inside.
As a result, the spray pattern is more favorably widened.
Further, in this embodiment, as shown in FIGS. 2A, 3B, and 4B, the upper portion and the lower portion of the injection hole 24 are formed in a cut-out state.
This notch is provided to reduce the adhesion of the contents to be sprayed, that is, to make the surface of the spray liquid attached smaller, thereby preventing dripping of the liquid after spraying. It can be done.

The forward movement of the push button 20 and its fixing will be described below.
Also in the second embodiment, the push button 20 is fixed between the side wall portions 12 and 12 of the cap body 10 as in the first embodiment.
A fitting recess is formed slightly toward the front from the center of the side walls 12 and 12 of the cap body 10, and the upper surface of the fitting recess is a flange 12h (FIGS. 2 and 3). .

In other words, when the fitting concave portion is formed in the side wall portion 12, the collar portion 12h is formed above the concave portion.
The front end corners 20k, 20k of the push button 20 are fitted into the fitting recess.
On the other hand, the rear end corners 20j, 20j on both sides of the push button 20 can be engaged with the engaging projections 12j, 12j provided at the rear ends of the fitting recesses on the side walls 12, 12.
This engagement convex part 12j consists of a protrusion provided in the up-down direction.

  With the above configuration, the cap main body 10 is removed from the aerosol container, and the push button 20 is moved in the forward direction, whereby the connecting portion between the connection hinge portion and the side wall portion 12 is cut, and both front end corner portions 20k of the push button 20 are cut. Is fitted into the fitting recess below the flange 12h of the side wall portion 12, and the rear end corner portions 20j on both sides of the push button 20 are engaged with the engagement convex portions 12j of the side wall portion 12, so that the push button 20 Is sandwiched and fixed between the side wall portions 12 and 12.

In this state, the cap main body 10 is attached to the upper end of the aerosol container so that the residual gas venting stem mounting part 28 provided behind the push-down button 20 is mounted on the stem of the container and the stem is pushed down. As a result, the residual gas is discharged to the outside.
Also in the second embodiment, the height of the contact portion of the residual gas vent stem mounting portion 28 is lower than the contact portion of the first outflow passage 21 of the push-down button 20. It is the same as in the first embodiment that the residual degassing state can be achieved simply by attaching 10 to the container.

Next, a third embodiment of the present invention will be described with reference to FIGS.
FIG. 5A is a perspective view thereof, and FIG. 5B is a partially cutaway perspective view thereof.
FIG. 6 shows the nozzle part of the third embodiment, in which (A) is a central horizontal sectional view and (B) is a central longitudinal sectional view.

The third embodiment is provided with a reinforcing cylinder as in the second embodiment, but the reinforcing cylinder 27 is formed so as to surround the entire nozzle portion 23.
In order to surround the entire nozzle portion 23, the upper portion and the lower portion thereof are cut out so as to respectively provide the cutout portions 27 k so as not to hinder the wide injection pattern of the contents.

Other configurations are the same as those of the second embodiment.
The nozzle portion 23 has a needle-like shape, and a nozzle hole 24 at the tip thereof is provided with a cutout 24 k in the vertical direction. The configuration that can be fixed between the wall portions 12 and 12 is exactly the same.
Thereby, the residual gas venting function can also be executed.

7 and 8 illustrate a fourth embodiment of the present invention.
FIG. 7A is a perspective view thereof, FIG. 7B is a half cutaway perspective view, FIG. 7C is an enlarged view of a portion C in FIG. A, and FIG. It is an enlarged view of D part.
FIG. 8 is a sectional view thereof.
This embodiment is basically the same as the third embodiment, except that reinforcing members 23h and 23h are formed on both sides of the nozzle portion 23.

That is, in the fourth embodiment, plate-like reinforcing members 23h, 23h are provided on both sides of the nozzle portion 23 in the lateral direction, and the both sides of the nozzle portion 23 and the inner wall of the outer reinforcing cylinder 27 are bridged. In this way, it is reinforced.
Other configurations are the same as those of the third embodiment.

A nozzle hole 24 is integrally formed at the tip of the needle-shaped nozzle portion 23, the nozzle hole 24 is formed with a cut in the vertical direction, and the upper and lower portions of the nozzle hole 24 are cut out.
In addition, the push button 20 is formed with a residual gas venting stem mounting portion 28, and the push button 20 can be moved forward to be sandwiched and fixed between the side wall portions 12, 12 of the cap body 10. .

  More specifically, as in the above embodiment, the cap body 10 is removed from the container, the push button 20 is moved in the forward direction, and the front end corners on both sides of the push button 20 are located on both side walls 12, 12 of the cap body 10. The press button 20 is engaged with the engagement recesses provided on the both side walls 12, 12 by engaging the rear end corners on both sides of the press button 20 with the engagement protrusions of the both side walls 12, 12. After fixing the cap body 10 to the container, the stem attaching portion 28 for removing the residual gas of the push-down button 20 is attached to the stem of the container and the residual gas is discharged. .

Although the embodiments of the present invention have been described above, various design changes can be made in the present invention as follows.
First, the first feature of the present invention is that the nozzle part is formed with a thin outer diameter and has a needle-like shape, so that it is not necessary to fit a separate nozzle piece or nozzle tip as in the prior art. That is, the nozzle and the nozzle part can be integrally formed.
Each of the above embodiments is realized by implementing this characteristic portion. In the first embodiment, a plate-shaped reinforcing member is further provided below the nozzle portion in this characteristic portion.

The inner diameter of the second outflow passage of the nozzle part is set within a range of about 0.4 mm to 1.0 mm, and the outer diameter of the nozzle part can be designed as necessary.
If the outer diameter of the nozzle part is set large, the reinforcing member is not necessary.
The length of the nozzle part may be such that the nozzle hole at the tip thereof is near the inside of the outer periphery of the cap body.

  The distance between the side wall portions of the cap body is sufficient as long as the user's fingers can enter on the rear side and the push button can be pushed down easily. What is necessary is just a space | interval which can be fitted and fixed with the provided fitting recessed part.

The connection hinge portion that connects the front lower end portion of the push button and the crowned portion of the cap body is also a plate-like body that is substantially L-shaped in side view in each of the above embodiments. Any material that can be bent freely may be used.
This bent portion can also be formed as a simple curved portion.
Although the connection part connected with a cap main body is provided in the both sides of this connection hinge part, this connection part should just be the intensity | strength of the grade which can be easily torn off.

The outer diameter of the reinforcing cylinder that is a reinforcing member that reinforces the nozzle portion can also be designed freely.
In addition, the notch provided in the nozzle hole at the tip of the nozzle portion can be changed in design so as to exhibit a wide spray pattern in the horizontal direction by being provided in the horizontal direction instead of the vertical direction.
Although a pair of reinforcing members provided in the fourth embodiment are provided in the horizontal direction on both sides of the nozzle portion, it is needless to say that two pairs of reinforcing members may be provided in an oblique direction.

  As described above, according to the present invention, the nozzle part can be integrally formed with the push button, and the nozzle part can be formed into a needle shape by being formed into a needle shape, and a wide injection pattern can be obtained. In addition, it is possible to provide a very convenient aerosol container integrated button cap of an aerosol container which can add a residual gas venting mechanism together with these functions.
