Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a metering discharge container, and more particularly to a metering discharge container in which a container body is squeezed to discharge the contents in the container body by a fixed amount.
[0002]
[Prior art]
Generally, a dispenser is known as a quantitative discharge container. In order to use this dispenser, the fingertip is applied to the push button provided on the top of the container while the container is held by hand, and a force is applied to the finger to press the spring movable push button.
[0003]
As another quantitative discharge container, a contact member for regulating the pushing width of the container main body is provided in the storage chamber of the container main body, and this squeezing deformation is performed when the pressing operation portion of the container main body is squeezed. The operation portion is brought into contact with the contact member, thereby restricting the amount of squeeze deformation of the container body within a certain range.
This fixed-quantity discharge container uses the abutting member to squeeze the pressing operation portion of the container main body within a certain range, and discharges the contents in the container main body from the container main body by a predetermined amount (for example, Patent Documents). 1).
[0004]
[Patent Document 1]
Japanese Patent Laid-Open No. 10-24950 (page 4, FIG. 1)
[0005]
[Problems to be solved by the invention]
However, in the above-described dispenser, since the container is gripped by hand during use, the fingertip is applied to the push button portion on the top of the container, and the force is applied to the finger to press the push button portion. Operation became difficult and room for improvement was left in terms of usability.
[0006]
In addition, this dispenser has a mechanism that sucks up the contents with a dip tube suspended in the container body, so that the contents easily remain as the remaining amount at the bottom of the container, and further, air is drawn when pressed, so the contents are discharged. There were also inconveniences such as the contents being scattered during the process.
[0007]
On the other hand, in the discharge container shown in Patent Document 1, it is necessary to dispose the abutting member from the opening (that is, the mouth) of the container body to the storage chamber of the container body. It could not be formed larger than the size of the mouth. Therefore, when the contact member is accommodated in the container body, the contact member is relatively small, and there is a problem that the space between the pressing operation portion of the container body and the contact member inevitably increases.
[0008]
Therefore, if the container body is squeezed until the pressing operation part of the container body comes into contact with the contact member, the amount of squeeze deformation of the container body becomes too large, and a large amount of content is discharged from the inside of the container body. The result was that
Therefore, in the discharge container shown in Patent Document 1, it has been difficult to make fine adjustments such that a small amount of content is discharged from the container main body at a constant amount.
[0009]
On the other hand, the thing of the said patent document 1 is a site | part (namely, press operation part) in a container main body as a device for making the space between a contact member and the press operation part of a container main body small. An example in which is recessed in advance is also disclosed.
[0010]
However, it is not preferable to dent the pressing operation portion in advance for reasons of container design.
Further, when the pressing operation part is recessed in advance, the container main body must be squeezed and deformed in a direction in which the pressing operation part is further recessed, so it is necessary to apply a large pressing force to the pressing operation part. There was room for improvement in terms of usability from the viewpoint.
[0011]
The present invention aims to solve all the above-mentioned problems by providing a quantitative discharge container that can accurately discharge a small amount of contents from a container in a certain amount and is excellent in usability and design. To do.
[0012]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the invention according to claim 1 is a quantitative method in which the container body is formed of a squeeze-deformable soft plastic, and the contents in the container body are discharged from the mouth by squeezing the container body. In the discharge container, the outer peripheral wall of the container body is covered with a cylindrical cover body, and a bridge portion that can be reversed toward the outer peripheral wall is formed on the cylindrical cover body, and the bridge portion is formed on the outer peripheral wall. The outer peripheral wall of the container body is squeezed and deformed by a certain amount, and the contents are discharged by a certain amount by this squeeze deformation.
[0013]
According to the quantitative discharge container according to the present invention, the outer peripheral wall of the container main body is covered with the cylindrical cover body, and the bridge portion is formed on the cylindrical cover body. The bridge portion is formed to be reversible toward the outer peripheral wall of the container body, and by inverting this, the outer peripheral wall is squeezed and deformed so as to be recessed by a certain amount.
In this way, the content can be discharged from the container main body by a certain amount.
[0014]
Next, by increasing the distance between the bridge part and the outer peripheral wall of the container body, the amount of squeeze deformation of the container body can be suppressed to a small amount, and a small amount of content can be discharged from the container body in a fixed amount. become.
[0015]
At the same time, the gap between the bridge portion and the outer peripheral wall of the container body can be reduced to reduce the amount of squeeze deformation of the container body, so that a large dent is formed in the outer peripheral wall of the container body as in the prior art. There is no need, and the container body can be squeezed and deformed by a certain amount only by reversing the bridge portion, and the usability can be improved.
[0016]
In addition, since the gap between the bridge portion and the outer peripheral wall of the container main body can be reduced without providing a large dent in the outer peripheral wall of the container main body, there is no design restriction.
[0017]
According to a second aspect of the present invention, the bridge portion secures a position where the pressing force is reduced while applying a pressing force to the bridge portion to deform the bridge portion from an original state to an inverted state. To do.
[0018]
During the process of applying a pressing force to the bridge portion to deform the bridge portion from the original state to the inverted state, a position where the pressing force to the bridge portion decreases is secured.
For this reason, when discharging the contents from inside the container body, the user can feel that the pressing force has decreased with the fingertip, and can detect the completion of a certain amount of content from the container body by the touch of the fingertip. Can do.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a metering discharge container according to the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a side view showing a metering discharge container according to the present invention, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB in FIG.
[0020]
1 to 3 includes a squeeze-deformable soft plastic that forms a container body 11, and a cap 15 is detachably attached to the mouth 14 of the container body 11. The cap 15 is attached and detached. Thus, the mouth 14 is configured to be openable and closable, and the cylindrical cover body 20 is placed on the container main body 11 so that the outer peripheral wall 12 of the container main body 11 is covered with the cylindrical cover body 20.
[0021]
The fixed-quantity discharge container 10 forms a bridge portion 21 that can be reversed toward the outer peripheral wall 12 of the container body 11, specifically, the formed pressing operation portion 13, on the cylindrical cover body 20. The pressing operation portion 13 of the outer peripheral wall 11 is squeezed by a certain amount by being inverted toward the pressing operation portion 13 of the outer peripheral wall 12.
[0022]
The container body 11 is made of squeeze-deformable soft plastic. For example, 0.6 mm thick polypropylene (PP), 0.6 mm thick high density polyethylene (HDPE), 0.5 mm thick polyethylene terephthalate ( PET) and the like can be used.
As a result, when the pressing operation portion 13 formed on the outer peripheral wall 12 of the container body 11 is squeezed and deformed by applying a pressing force, the outer pressing wall 13 is released from the pressing operation portion 13. Restores the original state before squeeze deformation.
[0023]
As the cylindrical cover body 20, polyethylene terephthalate (PET), PC (polycarbonate), polypropylene (PP), or the like can be used. As an example, the cylindrical cover body 20 was formed into a cylindrical body having a radius of 25 mm.
The bridge portion 21 is a bridge that is formed on the outer peripheral wall 22 of the cylindrical cover body 20 with a width dimension W and a length dimension L in the axial direction, and has a substantially tile shape as a whole.
As an example, the width dimension W of the bridge portion 21 is set to 10 to 50 mm (preferably 18 to 36 mm), and the length dimension L is set to 12 to 100 mm (preferably 15 to 40 mm).
[0024]
That is, the bridge portion 21 has a width dimension W in the circumferential direction on the outer peripheral wall 22 of the cylindrical cover body 20, and a pair of slits 23 are inserted in the axial direction of the cylindrical cover body 20, so that these slits 23 are connected. An arc-shaped cut line 24 is inserted to open a pair of cross-sectionally creased spaces 25.
[0025]
The bridge portion 21 is a bridge that is curved in a convex shape in the width direction on the outer peripheral wall 22 of the cylindrical cover body 20 and has a tile shape.
For this reason, as shown in FIG. 4, when the cap 15 of the fixed discharge container 10 is removed and the mouth 14 is opened, the fixed discharge container 10 is turned upside down, and then the bridge portion 21 of the cylindrical cover body 20 is pushed with the thumb 30. As shown in FIG. 5, a pressing force F is applied to the bridge portion 21 in the direction of the arrow toward the pressing operation portion 13 of the container body 11.
When the pressing force F is applied to the bridge portion 21, the bridge portion 21 reverses toward the pressing operation portion 13 of the container body 11 with the connecting portion 27 between the outer peripheral wall 22 of the cylindrical cover body 20 and the bridge portion 21 as a fulcrum. .
[0026]
Here, since the bridge portion 21 is formed in a tile shape, the reverse deformation amount of the bridge portion 21 increases as the pressing force F to the bridge portion 21 increases (see FIG. 7).
Then, as shown in the graph of FIG. 7, at the position P where the bridge portion 21 is inverted and deformed, the shape of the bridge portion 21 protrudes from the convex curve protruding outward as shown in FIG. 5 to the inner side shown in FIG. Deforms into a concave curve.
In this way, the bridge portion 21 can be reversely deformed inward by itself to secure a position where the pressing force F is reduced.
[0027]
Here, the measurement method and conditions of FIG. 7 will be described.
As a measuring instrument, Shimadzu Autograph AG-1 (Shimadzu Corporation) was used for measurement.
First, a pressing piston (a contact surface size: a circular piece having a diameter of 20 mm) of a measuring device was applied to the bridge portion 21, and a pressing force F was applied under a pressing condition of a pressing speed of 30 mm / min.
At the time of pressing, a receiving member (contact surface size: circular piece with a diameter of 20 mm) is fixedly installed on the outer peripheral wall 22 located on the opposite side of the pressing side of the cylindrical cover body 20, and the cylindrical cover body is measured at the time of measurement. Stable holding was made so that the entire 20 would not move, so that accurate measurement could be performed.
[0028]
As described above, the bridge portion 21 is formed in a convex-curved roof tile, so that a pressing force F is applied to the convex-curved side of the bridge portion 21 and the bridge portion 21 is deformed from the original state to the inverted state. (Specifically, the position where the pressing force F decreases can be secured at the position P shown in FIG. 7).
[0029]
Therefore, when discharging the contents from the container body 11 in the direction of the arrow as shown in FIG. 4, when the user reversely deforms the bridge portion 21, the user feels that the pressing force F has decreased, The completion of discharge of a certain amount of content from the inside of the container body 11 can be sensed by touch.
[0030]
Then, when the bridge portion 21 is reversely deformed by a certain stroke, the pressing operation portion 13 of the container body 11 is pressed by the bridge portion 21, and the container body 11 is squeezed by a certain amount, so that the content in the container body 11 is obtained. Can be discharged in a fixed amount in the direction of the arrow.
[0031]
Here, the discharge amount of the contents is determined by the volume change of the container main body 11, and the volume change of the container main body 11 is the outer peripheral wall when the pressing operation portion 13 of the container main body 11 is pressed by the bridge portion 21. 12 squeeze deformation amount.
[0032]
As a result, the amount of elastic deformation of the bridge portion 21 and the prior clearance S (see FIG. 2) between the bridge portion 21 and the pressing operation portion 13 of the container body 11 determine the content discharge amount.
Therefore, if the amount of elastic deformation of the bridge portion 21 and the clearance S between the bridge portion 21 and the pressing operation portion 13 of the container main body 11 are adjusted in advance, the desired contents are reliably discharged from the container main body 11 in a certain amount. Can be made.
[0033]
As an example, if the clearance S between the bridge portion 21 and the pressing operation portion 13 of the container main body 11 is increased to 2 mm, the amount of squeeze deformation of the container main body 11 can be suppressed to a small amount.
In this way, it is possible to discharge a small amount of the contents from the container main body 11 at a constant rate.
[0034]
As described above, in order to increase the clearance S between the bridge portion 21 and the pressing operation portion 13 of the container body 11 to 2 mm, it is necessary to keep the pressing operation portion 13 small.
As a result, it is possible to squeeze the container body 11 by a certain amount only by pressing the pressing operation unit 13 relatively lightly by the bridge portion 21, and the usability can be improved.
[0035]
Furthermore, since the pressing operation part 13 formed in the outer peripheral wall 12 of the container main body 11 is formed in the site | part which faces the bridge part 21, the pressing operation part 13 can be hidden with the bridge part 21, and like the prior art The dent formed in the outer peripheral wall 12 of the container body 11 is not exposed, and the appearance can be kept good.
[0036]
Next, according to the fixed-quantity discharge container 10 of the present invention, a small amount of contents can be discharged from the container main body 11 in a fixed amount with a simple configuration in which the bridge portion 21 is formed in the cylindrical cover body 20. The manufacturing cost of the fixed discharge container 10 can be suppressed.
[0037]
In the above embodiment, the example in which the clearance S between the bridge portion 21 and the outer peripheral wall 12 is adjusted by forming the pressing operation portion 13 having a concave shape on the outer peripheral wall 12 of the container body 11 has been described. Without being limited thereto, it is also possible to provide the outer peripheral wall 12 with a pressing operation portion 13 that does not have a concave shape.
The container body 11 can be applied to various containers such as blow bottles.
[0038]
【The invention's effect】
As described above, according to the metering discharge container according to the first aspect, the outer peripheral wall of the container main body is covered with the cylindrical cover body, and the cylindrical cover body is configured to have the bridge portion. The outer wall of the container body is squeezed and deformed so that the outer wall can be squeezed so that the outer wall is recessed by a certain amount. By doing so, the contents can be discharged from the container body in a certain amount.
[0039]
In addition, by increasing the distance between the bridge portion and the outer peripheral wall of the container body, the amount of squeeze deformation of the container body can be suppressed to a small amount. This makes it possible to discharge a small amount of the contents from the container body.
[0040]
In addition, by increasing the distance between the bridge portion and the outer peripheral wall of the container main body and suppressing the amount of squeeze deformation of the container main body to a small amount, there is no need to form a recess in the outer peripheral wall of the container main body as in the prior art, By simply pushing the outer peripheral wall of the container body lightly, the container body can be squeezed and deformed by a certain amount, and the usability can be improved.
[0041]
Moreover, even if the pressing operation part having a concave shape is not provided on the outer peripheral wall of the container main body, the distance between the bridge part and the outer peripheral wall of the container main body can be reduced, and the design is not restricted.
[0042]
Since the position where the pressing force of the bridge portion decreases is secured in the middle of deforming the bridge portion from the original state to the inverted state by applying the pressing force to the bridge portion, the second aspect of the present invention can discharge the contents from the container body. In addition, the user can sense the completion of discharge of a certain amount of content from the inside of the container body by feeling that the pressing force has decreased, and a user-friendly quantitative discharge container can be obtained.
