Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dispenser cap and a dispenser, and more particularly to a dispenser cap detachably attached to a dispenser for discharging contents from a nozzle and a dispenser to which the cap is attached.

[0002]

2. Description of the Related Art For example, a container having cosmetics such as perfume as a content is provided with a pump dispenser (hereinafter referred to as a dispenser) for discharging the content by pressing a button provided on a head. There are things that are. By using this dispenser, operations such as removing the lid and tilting the container body in order to take out the contents become unnecessary, and operability is improved.
There is an advantage that a predetermined amount of contents can be taken out every time by operating a button.

[0003] Usually, in order to prevent erroneous operation during transportation during shipping or during carrying, a cap is provided to cover the buttons and nozzles and to protect the buttons and nozzles from external pressing. . FIG. 8 shows a dispenser and a cap thereof according to an example of the related art. As shown in the figure, the dispenser 1 includes a button 4, a nozzle 5, a mounting unit 6, and the like. By being fixed to the container 3, the dispenser 1
The contents are discharged from the nozzle 5 by the pump action of (1).

The cap 2 is attached to the tip of the end of the dispenser 1 so as to protect the button 4 of the dispenser 1, has a cylindrical shape with a bottom, and is simply formed on the outer periphery of the mounting portion 6. It is configured to be inserted into, engaged with, and attached to the attached mounting portion 7.

[0005]

However, in the above-described dispenser 1, after the discharging operation is performed, the contents slightly remain in the nozzle 5. This is Dispenser 1
This is because the valve mechanism (valve according to the related art for discharging and stopping the discharge of the contents; not shown) and the nozzle 5 are slightly separated from each other.

Therefore, the configuration of the current dispenser 1
In particular, it is difficult to prevent the contents from remaining after ejection without changing the valve mechanism and its disposition position. Then, a problem that occurs when the contents remain in the nozzle 5 is pointed out. In other words, the remaining contents are
When it comes into contact with air originating from the space between the nozzle 5 and the cap 2 and is not used for a while, the phenomenon of deterioration and discoloration or solidification occurs.

If the discolored or solidified content remains attached to the nozzle 5, the user will feel uncomfortable, and if the solidified content is clogged, the content and the discharge /
A problem arises in that it cannot be taken out.
In order to solve this problem, there is a conventional example in which an elastically deformable seal member that opens and closes according to a container internal pressure that is changed by a button operation is installed at a discharge port of a nozzle.

In this conventional example, the seal member, which normally closes the discharge port, is opened by the pressure inside the container which is increased by pressing the button, and the contents can be discharged. Then, when the discharge is completed, the increase in the internal pressure is eliminated, and the discharge port is again closed by the seal member. As a result, it is possible to minimize contact of the remaining contents of the nozzle with air.

[0009] However, when the internal pressure is eliminated by pressing the button completely, the seal member returns to the original installation position at that stage and closes the discharge port. As a result, the contents left in the vicinity of the discharge port by the discharge operation return naturally to the inside of the nozzle after the discharge operation, that is, there is no so-called suction, and instead, a large amount of contents is left in the vicinity of the discharge port. Would be.

[0010] Therefore, the solidification of the contents occurs due to the contact with air, which cannot be completely suppressed by the sealing member, and the large amount of the contents may cause the problem of clogging or the like more easily. Further, as shown in FIG. 9, there is also provided a dispenser 1A having a sealing portion 8 for sealing the nozzle 5 inside the cap in order to prevent solidification of the contents at the discharge port. However, in this configuration, if the button 4 loosens or becomes unsteady due to a formation error inevitably generated during manufacturing, the seal portion 8 and the nozzle 5 are separated from each other, or conversely, the button 4
If it is tilted toward the sealing portion 8, it becomes a resistance when the cap 2 is fitted, and the resistance becomes too strong, and as a result, there is a problem that the sealing cannot be performed strongly.

Therefore, the content remaining in the nozzle 5 comes into contact with air, and the content is solidified. As a result, a problem such as clogging of the nozzle 5 due to the solidified material also occurs. Therefore, an object of the present invention is to provide a novel dispenser cap and dispenser that solve the above-mentioned problems.

Another object of the present invention is to provide a dispenser cap and a dispenser configured to suppress solidification of the contents remaining in the nozzle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. (Embodiment 1) FIGS. 1 and 2 show a cap 10 of a dispenser according to a first embodiment of the present invention. This cap 1
Numeral 0 is attached to a dispenser 12 provided in the container 11.

On the other hand, the dispenser 12 to which the cap 10 is attached is provided with a button 13, a nozzle 14, a mounting part 15, and the like, and the mounting part 15 is mounted on the upper part of the container 11. Then, the contents in the container 11 are discharged from the nozzle 14 (having the discharge port 17) by a button operation. This button 13 is attached to the mounting section 1
5 does not rotate.

The cap 10 is detachably attached to the dispenser 12 and protects the nozzle 14. The cap 11 has the shape of a square prism.
Corresponds to the shape of a square, and has the shape of a square cylinder with a bottom. Further, the inner cap 22 has an inner cap 22 in contact with the cap main body 21 at the upper surface inside the cap main body 21 to form a double structure, and leakage of the contents from the nozzle 14 to the side wall 23 of the inner cap 22 is prevented. The cap portion 24 having a function as a preventing portion is formed, and a space 25 is provided between the side wall 23 where the cap portion 24 is formed and the cap body 21.

Therefore, when the cap 10 is mounted, the stopper portion 24 is urged by the nozzle 14 and can be displaced within the cap body 21 due to the presence of the space portion 25.
Further, when the cap 10 is mounted on the dispenser 12, the tip portion is tapered so as to guide the cap mounting position with respect to the dispenser 12 so that the stopper portion 24 having a leakage preventing function engages with the nozzle 14. 14 is fixed to the inner cap 2.
The second cap body 21 is provided on a side wall 23 that is in contact with the cap body 21.

Therefore, when the cap 10 is mounted, the stopper portion 24 engaged with the nozzle 14 is pressed by the nozzle 14 securely fixed by the guide portion 26. In response to this pressing, a positional change corresponding to the thickness of the space 25, which is a change from an initial setting position before mounting to the dispenser 12 to a position in contact with the cap body 21, is possible. As shown in FIG. 2, the side wall 23 of the inner cap 22 having a space between itself and the cap main body 21 is provided with a guide portion 26 on the side wall 23 and in contact with the cap main body 21 and the plug 23. It has a thinner structure than the provided portion, and makes the displacement of the closure portion 24 relatively easy.

As described above, by providing the thin portion, it is possible to control the ease of displacement of the plug 24. Then, the nozzle 14 can be engaged with the nozzle 14 at an appropriate point to seal the discharge port 17 of the nozzle 14 in the course of fluctuation, and the side wall 2 generated by the pressing from the nozzle 14 can be formed.
Since there are three portions of repulsive force, the nozzle 14 can be strongly engaged with the guide portion 26 and the side wall 23 by sandwiching the nozzle 14 therebetween.

At this time, regarding the material of the inner cap 22, it is preferable that the inner cap 22 is relatively soft so as to have the above-mentioned action. However, since an appropriate repulsion is required for the pressure from the nozzle 14, a resilient soft material such as polyethylene, rubbers, or an elastomer is preferable. However, general resin materials have appropriate flexibility and can be used, and by adjusting the thickness of the inner cap appropriately, it is possible to secure the necessary flexibility for most members. For this reason, it is not necessary to limit to the above members. Members can be selected from a wide range in consideration of heat resistance, chemical resistance reliability, and the like.

In the case of the present embodiment, four stopper portions 24 are formed on the side wall 23 of the inner cap 22 at approximately 90 ° intervals, and four corresponding spaces 25 are similarly provided. . Therefore, the cap 1 for the dispenser 12
The mounting mode of 0 is four modes. In other words, the degree of freedom of attaching the cap 10 to the dispenser 12 is four degrees of freedom. This is determined in consideration of the shape of the container in this embodiment and the shape of the cap 10 corresponding thereto, and it is naturally possible to set the degree of freedom of attachment to another setting.

That is, in the case of this embodiment, the container is a kind of so-called irregularly shaped container and has a shape of a square prism, and when the cap is formed in a shape conforming to the shape of the container, the shape is derived from the shape. Desirable degrees of freedom are four degrees of freedom. However, by giving an appropriate cap attaching operation instruction to the user by using a pattern or pattern on the surface of the container, for example, one or more of the four closure portions 24 (of course, three Below) to form the cap 10 and use it with only one to three degrees of freedom using only the provided plugs 24.

In this case, a guide portion 26 is provided at the position where the stopper portion 24 has been removed to enhance the fixing of the nozzle 14 and the guide function of the guide portion 26 to enhance the usable stopper portion 24. It is also possible to guide the attachment of the cap to a certain position. In the case of a cap corresponding to another deformed container, it is possible to appropriately provide a space 25 corresponding to the closure portion 24 in the inner cap 22 and the cap main body 21 in accordance with the desired degree of freedom in mounting the cap. Of course, it is also possible to provide a smaller number of closures 24 with a corresponding space 25 than the desired degree of freedom.

Further, when a cylindrical cap is used for a container formed of a cylindrical cylinder, a space 25 corresponding to the stopper portion 24 is appropriately formed in the inner cap 22 similarly.
It is possible to use the same cap as in this embodiment by providing the cap and the cap body 21. In this case, the desired degree of freedom in attaching the cap is infinite, but, similarly to the above case, the desired freedom can be achieved by appropriately arranging and strengthening the guide portion 26 and further by giving appropriate instructions to the user. It is also possible to provide the inner cap and the cap main body with about 1 to 10 closure portions and corresponding spaces that are less than the number of degrees.

In this embodiment, as shown in FIG. 2, two guides are provided between adjacent plugs 24. The shape and the number of the guide portions are not particularly limited as shown in this figure. In order to enhance the guide function and the function of fixing the nozzle, the number is further increased, and between the adjacent stopper portions 24, It is also possible to provide three or more of them, or to increase the thickness of each one to make the structure stronger.

Conversely, it is also possible to reduce the number, and to provide only one or more and two or less each between the adjacent plugs 24. In that case, the guide portion 26 provided
It is desirable to have a sufficient thickness and structural strength so that the nozzle 14 can be sufficiently supported.
With the above configuration, the stopper portion 24 provided on the cap 10 can reliably seal the nozzle 14, and a gap is formed between the stopper portion 24 and the nozzle 14, and the gap is left inside the nozzle 14. The contents that come in contact with air
It is possible to efficiently prevent the contents from solidifying.

As a result, deterioration and discoloration of the contents in the nozzle 14 which has been a problem can be prevented, and the nozzle 14 can be prevented from being clogged with solidified contents. (Embodiment 2) FIGS. 3 and 4 show a dispenser cap 30 and a dispenser 52 according to a second embodiment of the present invention.
Is shown.

The characteristic structure of the dispenser will be described later, but the main structure of the dispenser will be briefly described. The button 53, the nozzle 54, and the mounting portion 55
The mounting part 55 is attached to the upper part of the container 51. The nozzle 54 is operated by a button operation.
It is configured to discharge the contents in the container 51 from (having the discharge port 57).

On the other hand, the cap 30 is detachably attached to the dispenser 52 and protects the nozzle 54. The cap 30 has a bottomed cylindrical shape corresponding to the shape of the container 51 having a bottomed cylindrical shape. It has the shape of And, while having an inner cap 32 in contact with the cap main body 31 at the upper surface inside the cap main body 31, forming a double structure,
A space 35 is formed between the side wall 33 portion of the inner cap 32 and the cap body 31, and the cap body 31 of the side wall 33 is formed.
It is configured such that it can be changed in the direction, and when the cap is attached, the discharge port 57 of the nozzle and a part of the side wall 33 abut.

Further, when the cap is mounted, the tip portion has a tapered portion to perform a guide function for mounting the cap 30, and the guide portion 36 for fixing the inner cap 32 by suppressing positional fluctuation such as wobble of the nozzle 54 is fixed. It is provided on the side wall 33 at a position above a position where the nozzle 54 is located. Therefore, when the cap 30 is attached, the side wall 33 in contact with the nozzle 54 is pressed by the nozzle 54 securely fixed by the guide portion 36. And, in response to this pressing,
It is possible to change the position corresponding to the thickness of the space 35, which is a change from the initial setting position before mounting to the dispenser 52 to the position in contact with the cap body 31.

It is possible to make contact with the nozzle 54 at an appropriate point in the course of fluctuation, and the guide portion 36 is formed by the repulsive force of the side wall 33 caused by the pressure from the nozzle 54.
Can strongly contact the nozzle 54 with the nozzle 54 interposed therebetween. At this time, the inner cap 22
As for the material, it is preferable that the material is relatively soft so as to have the above function. However, since an appropriate repulsion is required for the pressing from the nozzle 54, a resilient soft material such as polyethylene, rubbers, or an elastomer is preferable.

However, general resin materials have appropriate flexibility and can be used, and by adjusting the thickness of the inner cap appropriately, it is possible to secure the necessary flexibility for most members. Therefore, it is not necessary to limit to the above members. Members can be selected from a wide range in consideration of heat resistance, chemical resistance reliability, and the like. In this embodiment, eight guide portions are provided at appropriate intervals as shown in FIG. The shape and the number of the guide portions are not particularly limited as shown in this figure. To enhance the guide function and the function of fixing the nozzle, the number and the thickness of each one are increased. It is also possible to make the structure stronger.

Conversely, the number can be reduced. In this case, it is desirable that the provided guide portion 36 has a sufficient thickness and is structurally strong so that the nozzle 54 can be sufficiently supported. Next, regarding the dispenser 52, the dispenser 52 has the above-described configuration, and has the following features in the nozzle 54 and the discharge port 57 thereof.

The nozzle 54 is connected to the side wall 3 of the inner cap 32 with which the discharge port 57 of the nozzle comes into contact when the cap is attached.
It is formed according to the shape of the side wall 33 so as to be substantially sealed by the three parts. FIG. 5 is a partial cross-sectional view showing the structure of the nozzle 54 in the button 53 of the dispenser 52. Specifically, the nozzle outlet 57 has an inclination angle of 70 ° to 88 ° (in FIG. 5, (indicated by θ), the dispenser 52 is formed as a flat inclined surface which is inclined toward the main body side, is upward, and is formed so as to be substantially sealed by the side wall 33 portion of the inner cap 32 which abuts.

Accordingly, sufficient contact between the side wall portion 33 of the inner cap 32 and the nozzle 54 is possible, and in the abutting state, the sealing performance between the inner cap side wall portion in all areas of the nozzle outlet is improved. Higher. Therefore,
The inner cap 32 provided on the cap 30 is
Can be reliably sealed, a gap is formed between a part of the cap 30 and the discharge port 57 of the nozzle 54, and the contents remaining in the nozzle 54 come into contact with air, and the discharge of the nozzle 54 It is possible to efficiently prevent the contents near the outlet 57 from being solidified.

FIGS. 6 and 7 are partial sectional views showing another example of the structure of the nozzle 54 in the button 53 of the dispenser 52. FIG. As shown in FIG. 6, in order to improve the sealing property of the side wall 33 of the discharge port 57, as shown in FIG.
A, the inner wall 61 of the nozzle at the tip of the nozzle 54A
It is also possible to provide an airtight rib 62 which is provided extending from the portion toward the distal end and has a convex cross section.

As shown in FIG. 7, the tip of the nozzle forming the discharge port 57B is inclined so that, in a longitudinal section, the outer wall 71 extends toward the distal end with respect to the inner wall 72 and becomes higher. It is also possible to have it formed. In each of the examples of FIGS. 6 and 7, since the tip of the nozzle 54 forming the discharge port 57 is convex and sharp, the area where the nozzle 54 contacts the side wall 33 can be reduced, and the discharge port 57 can be reduced. This makes it possible to ensure uniform contact between the nozzle 54 and the side wall 33 for obtaining a substantial sealing property in all regions.

Further, since the side wall 33 in contact with the nozzle 54 is slightly curved so as to form a cylindrical shape due to the shape of the inner cap 32, the discharge port 5 is formed in accordance with the curvature.
It is also possible to form the shape of the tip of the nozzle 54 having 7. In that case, the shape formed by the discharge port 54 is, of course,
The corresponding side wall 33 is slightly curved in the same shape.

By forming the shape of the discharge port 54 in this manner, uniform contact between the nozzle 54 and the side wall 33 can be ensured, and higher sealing performance can be obtained in the entire area of the discharge port 57. . In the present embodiment, the cap 30 is formed in a cylindrical shape in accordance with the cylindrical shape of the container 51. In order to increase the degree of freedom in mounting the cap 30, the guide portion 36 is higher than the position of the nozzle 54 when the cap is mounted. It is set on the inner cap 32.

However, when a high degree of freedom is not required even for a cylindrical container, or when the present invention is applied to a deformed container / cap which has no problem even with a lower degree of freedom in mounting, the cap body 31 of the cap 30 may be used. To the shape of the container to which the cap is applied, and furthermore, the cap body 31 has an inner cap 32 in contact with the cap body 31 at the upper surface thereof to form a double structure, and the side wall 33 portion of the inner cap 32 and the cap body 31 A space 35 is formed between the side wall 33 and the side wall 33 so that the side wall 33 can move in the direction of the cap body 31. Further, when the cap is attached, the discharge port 57 of the nozzle and the side wall 33
Are configured to abut against each other.

When the cap is mounted, the guide portion 36 for fixing the nozzle 54 while suppressing positional fluctuations such as wobble of the nozzle 54.
May be provided on the side wall 33 of the inner cap 32 from a position above the nozzle 54 to a position below the nozzle 54. With such a configuration, the guide portion 36 can exhibit a higher guide function and a nozzle fixing function.
