Description

The present invention relates to a container in which a drug or the like is stored, and particularly belongs to the technical field of a structure having a push-down type operation button.

For example, a push-down type operation button is provided on the upper part of the aerosol container containing the medicine, and by pushing down this operation button, the discharge pipe on the upper part of the aerosol container is pushed and operated to externally remove the medicine contained in the aerosol container. A container with an operation button configured to discharge into a container is known (see, for example, Patent Document 1).

In Patent Document 1, a tubular shoulder cover is attached to the upper part of an aerosol container, a cap is fitted to the upper part of the shoulder cover, and an operation button is inserted into a hole formed in the center of the cap for operation. The discharge pipe can be pushed and operated by pushing down the operation button with the lower part of the button fitted to the discharge pipe of the aerosol container. On the outer peripheral surface of the shoulder cover of Patent Document 1, four engaging protrusions are formed at equal intervals in the circumferential direction. Further, an annular engaging protrusion is formed on the inner peripheral surface of the cap. The engaging protrusion of the shoulder cover is located above the engaging protrusion of the cap over the engaging protrusion of the cap when the cap is fitted from the upper side of the shoulder cover, and is engaged with the engaging protrusion of the cap. It fits. This attaches the cap to the shoulder cover.

Japanese Patent No. 5491140

By the way, when a push-down type operation button is provided as in Patent Document 1, the user puts his finger on the operation button from the side opposite to the drug discharge side (anti-discharge side) and applies a force downward. However, due to the fact that the finger is hung on the operation button from the anti-discharge side, if the user operates it without being aware of it, the force is also applied to pull the operation button toward the user side. The pulling force on the user side acts as a pulling force on the counter-discharge side with respect to the operation button.

Here, when a pulling force acts on the operation button of Patent Document 1 on the anti-discharge side, the operation button comes into contact with the cap and a pulling force acts on the cap as well. This cap is attached to the shoulder cover by the engaging force of the four engaging protrusions formed on the shoulder cover, because the four engaging protrusions are only provided at intervals in the circumferential direction. When the cap is pulled to the anti-discharge side, if the force is large, the engaging protrusion may be disengaged and the cap and the operation button may be disengaged from the shoulder cover.

In order to prevent this, it is conceivable to increase the amount of protrusion of the engaging protrusions, but if this is done, it is necessary to forcibly push in with a large force when engaging each engaging protrusion. Occasionally, the engaging protrusions may be worn or a part of the engaging protrusions may be damaged, which may lead to a decrease in the engaging force, and it may not be possible to prevent the cap and the operation button from coming off.

The present invention has been made in view of this point, and an object thereof is to prevent each member from coming off the container body when the operation button is pushed down by putting a finger on the operation button from the anti-nozzle portion side. To do.

In order to achieve the above object, in the present invention, a cover-side engaging portion extending from the nozzle portion side to both sides is formed on the tubular cover, and the cover-side engaging portion engages with the tubular base. The base-side engaging portion is formed so as to extend from the nozzle portion side to both sides so that at least one of the cover-side engaging portion and the base-side engaging portion is discontinuous on the anti-nozzle portion side.

The first invention is
A container body provided with a discharge pipe that discharges the contents by being pushed, and
A push-down type operation button that fits into the discharge pipe and pushes the discharge pipe.
With the cylindrical base attached to the container body,
In a container with an operation button, which is attached to the outside of the tubular base in a fitted state and has a tubular cover formed so as to surround the circumference of the operation button.
The operation buttons, the cylindrical base, and the tubular cover are all made of resin and are made of separate members.
The operation button is provided with a nozzle portion communicating with the discharge pipe so as to project in a direction intersecting the center line of the discharge pipe.
The operation button is formed with a finger mounting surface on which the user's finger is placed from the side opposite to the nozzle portion opposite to the nozzle portion.
On the inner peripheral surface of the tubular cover, a cover-side engaging portion extending continuously in the circumferential direction of the discharge pipe is formed from the nozzle portion side of the tubular cover to both sides.
On the outer peripheral surface of the cylindrical base, a base-side engaging portion with which the cover-side engaging portion engages is continuous from the nozzle portion side of the tubular base to both sides in the circumferential direction of the discharge pipe. Formed to extend
At least one of the cover-side engaging portion and the base-side engaging portion is discontinuous so as not to be formed on the anti-nozzle portion side.

According to this configuration, the cover-side engaging portion of the tubular cover engages with the base-side engaging portion of the tubular base, whereby the tubular cover is attached to the tubular base. Then, at the time of use, the user places his / her finger on the finger resting surface of the operation button and presses down the operation button. At this time, since the finger is placed on the finger resting surface from the anti-nozzle portion side, a pulling force acts on the operation button on the anti-nozzle portion side, and this force is a cylinder that surrounds the operation button from the operation button. It is also transmitted to the cover, and the tubular cover is pulled toward the anti-nozzle part. Since the cover-side engaging portion of the tubular cover extends from the nozzle portion side to both sides and engages with the similarly extending base-side engaging portion, they are arranged at equal intervals as in the conventional example. Compared with the case where the four divided engaging protrusions are provided, the proof stress when the tubular cover is pulled toward the anti-nozzle portion side is largely secured.

Further, when the tubular cover is attached to the tubular base, at least one of the cover side engaging portion and the base side engaging portion is not formed on the anti-nozzle portion side, so that the cover side engaging portion and the base side are not formed. The force required to engage with the engaging portion is small. Even if at least one of the cover-side engaging portion and the base-side engaging portion is not formed on the anti-nozzle portion side, the above-mentioned pulling force is applied on the anti-nozzle portion side from the viewpoint of disengagement of the tubular cover. Since it has almost no effect, the decrease in yield strength when pulled as described above is avoided.

The second invention is the first invention.

(Assembly method)
Next, a method of assembling the container 1 with an operation button configured as described above will be described. After molding the operation button 20, the cylindrical base 30, and the tubular cover 40, the operation button 20 is first assembled to the tubular cover 40. That is, the operation button 20 is inserted from below the tubular cover 40 into the peripheral wall portion 43 of the tubular cover 40, and at this time, the tip end portion of the nozzle portion 23 is first inserted into the peripheral wall portion 43. , The tip portion is inserted into the notch portion 43a. Then, the button body 21 is inserted into the peripheral wall portion 43. When inserting the button body 21 into the peripheral wall portion 43, the left guided portion 24b of the button body 21 is inserted into the left guiding opening 46a of the tubular cover 40 from the lower end portion, and the right side of the button body 21 is inserted. The guided portion 25b is inserted into the right guide opening 47a of the tubular cover 40 from the lower end. When the button body 21 is inserted deeper into the peripheral wall portion 43, it is guided by the left guide opening 46a and the right guide opening 47a, so that the button body 21 can be smoothly inserted. When the button body 21 is completely inserted into the peripheral wall portion 43, the protrusions 26a and 26a of the operation button 20 come into contact with and engage with the ridge portion 41d of the tubular cover 40 from above, so that the operation button 20 has a cylindrical shape. It will not come off while temporarily assembled to the cover 40.

After that, the annular wall portion 34 of the tubular base 30 is inserted inside the fitting wall portion 41 of the tubular cover 40, and the fitting wall portion 41 is fitted to the outside of the annular wall portion 34 to form a tubular shape. The base-side engaging protrusion 39 of the annular wall portion 34 of the cylindrical base 30 is inserted into the cover-side engaging groove portion 42 of the fitting wall portion 41 of the cover 40 to engage the two. When the base-side engaging protrusion 39 is inserted into the cover-side engaging groove 42, the fitting wall portion 41 and the annular wall portion 34 are elastically deformed, and the base-side engaging protrusion 39 is elastically deformed. , The base-side engaging protrusion 39 can be inserted into the cover-side engaging groove 42. Further, since the base side engaging protrusion 39 and the cover side engaging groove 42 have discontinuous portions, the force required to engage the base side engaging protrusion 39 and the cover side engaging groove 42 is small. I'm done.

The discontinuous portion may be formed only on one of the base side engaging protrusion 39 and the cover side engaging groove 42. Further, the base-side engaging portion may be used as a groove portion, and the cover-side engaging portion may be used as a protrusion.

Next, the upper portion of the container body 10 is inserted into the inner cylinder portion 32 from the lower end portion of the inner cylinder portion 32 of the tubular base 30, and the ridge portions 32a and 32a shown in FIG. 17 and the like are fitted to the upper portion of the container body 10. Let me. As a result, the tubular base 30 is attached to the container body 10. The tubular base 30 is firmly attached to the container body 10 so as not to rotate together with the operation button 20 when the user tries to rotate the operation button 20.

As shown in FIG. 5, when the tubular base 30 is attached to the container body 10, the upper side of the discharge pipe 13 is inserted into the lower side of the fitting cylinder portion 27b and fitted.

(Action and effect of the embodiment)
Next, the operation and effect of the container 1 with an operation button configured as described above will be described. Since the left guided portion 24b and the right guided portion 25b of the operation button 20 are inserted into the left guide opening 46a and the right guide opening 47a of the tubular cover 40, the force for rotating the operation button 20 is It is transmitted to the tubular cover 40.

Therefore, when the operation button 20 is rotated to the left, the tubular cover 40 also rotates in the same direction. When the tubular cover 40 rotates until the stopper portion 30b of the tubular base 30 enters the right recessed portion 41c of the tubular cover 40, the stopper portion 30b enters the right recessed portion 41c and engages with the cylindrical cover 40. The rotation of the cover 40 is stopped and the cover 40 can be pressed. At this time, since the mark portion 40a provided on the outer peripheral surface of the fitting wall portion 41 of the tubular cover 40 coincides with the pressable state display portion 30f of the tubular base 30, the user presses the operation button 20. It is easy to understand that it is possible.

When the operation button 20 is in the pressable state, the rear projecting piece 34a of the cylindrical base 30 is located directly below the notch 26b of the rear wall portion 26 of the operation button 20, so that the rear projecting piece 34a is located. It does not prevent the operation button 20 from being pressed. Further, when the operation button 20 is in a pressable state, the lower end portion of the left guide opening 46a of the tubular cover 40 is directly above the left plate portion 38b of the tubular base 30 and the left projecting piece 34b. Since it is located, the left guided portion 24b of the operation button 20 can be inserted between the left plate portion 38b of the tubular base 30 and the left projecting piece 34b from the lower end portion of the left guiding opening 46a. The left plate portion 38b and the left projecting piece 34b do not hinder the pressing of the operation button 20. Further, when the operation button 20 is in the pressable state, the lower end portion of the right guide opening 47a of the tubular cover 40 is directly above the right plate portion 38c of the tubular base 30 and the left projecting piece 34c. Since it is located, the right guided portion 25b of the operation button 20 can be inserted between the right plate portion 38c of the tubular base 30 and the right projecting piece 34c from the lower end portion of the right guiding opening 47a. The right plate portion 38c and the right projecting piece 34c do not hinder the pressing of the operation button 20.

Therefore, when the user puts his / her finger on the finger resting surface 27a of the operation button 20 and pushes down the operation button 20, the rear projecting piece 34a of the tubular base 30 is inserted into the notch 26b of the rear wall portion 26 of the operation button 20. Further, the left guided portion 24b of the operation button 20 is inserted between the left plate portion 38b and the left projecting piece 34b, and the right guided portion 25b of the operation button 20 is further inserted between the right plate portion 38c and the right project piece 34c. It is inserted between and. As a result, the fitting cylinder portion 27b of the operation button 20 pushes the discharge pipe 13 of the container body 10 to operate. The contents discharged from the push-operated discharge pipe 13 flow into the nozzle portion 23 through the discharge passage 27d of the operation button 20 and are discharged. Since the nozzle portion 23 is inclined, the contents can be effectively ejected diagonally upward.

When the operation button 20 is pressed down, the operation button 20 is guided downward by the left guide opening 46a and the right guide opening 47a of the tubular cover 40, so that the operation can be easily performed. Further, when the operation button 20 in the pressable state is pressed down, the left side contact surface 24a and the right side contact surface 25a of the operation button 20 and the left side button support wall portion 46 and the right side button support wall portion of the cylindrical cover 40 are formed. Since there is a gap between the cylinder and the 47, the sliding resistance does not increase and good operability can be obtained.

When the user places his finger on the finger mounting surface 27a of the operation button 20 and pushes down the operation button 20, since the finger is placed on the finger mounting surface 27a from the rear side on the anti-nozzle portion 23 side, the operation button 20 A pulling force acts on the rear side, and this force is transmitted from the operation button 20 to the tubular cover 40, and the tubular cover 40 may be pulled to the rear side. Since the cover-side engaging groove 42 of the tubular cover 40 extends from the front side to both the left and right sides and engages with the similarly extending base-side engaging protrusion 39, they are evenly spaced as in the conventional example. Compared with the case where the four engaging protrusions arranged and divided are provided, the proof stress when the tubular cover 40 is pulled to the rear side is largely secured. As a result, it is possible to prevent the cylindrical cover 40 and the operation button 20 from coming off the tubular base 30 when the operation button 20 is operated.

There is a discontinuous portion on the rear side where the base side engaging protrusion 39 and the cover side engaging groove 42 are not formed, but the above-mentioned pulling force is from the viewpoint of preventing the tubular cover 40 from coming off. Since it has almost no effect on the rear side of the tubular cover 40, a decrease in proof stress when pulled as described above is avoided.

Further, when the operation button 20 in the pressable state is rotated to the right, the cylindrical cover 40 also rotates in the same direction, and the stopper portion 30b of the cylindrical base 30 becomes the left recessed portion 41b of the tubular cover 40. When the cylindrical cover 40 rotates until it enters, the stopper portion 30b enters and engages with the left recessed portion 41b, whereby the rotation of the cylindrical cover 40 is stopped and the tubular cover 40 is in a non-pressable state. At this time, since the mark portion 40a provided on the outer peripheral surface of the fitting wall portion 41 of the tubular cover 40 coincides with the non-pressable state display portion 30e of the tubular base 30, the user can press the operation button 20. It can be easily grasped that it is in a non-pressable state.

When the operation button 20 is in the non-pressable state, the rear projecting piece 34a of the cylindrical base 30 is located at a position away from the notch 26b of the rear wall portion 26 of the operation button 20, so that the rear projecting piece is located. The 34a abuts on the lower end of the rear wall portion 26 of the operation button 20, and the operation button 20 cannot be pressed. Further, when the operation button 20 is in the pressable state, the left guided portion 24b of the operation button 20 is located above the left arc plate portion 36 of the cylindrical base 30, so that the left arc plate portion 36 is the operation button. The operation button 20 cannot be pressed because it comes into contact with the lower end of the guided portion 24b on the left side of the 20.

For example, when the container 1 with an operation button is dropped, since the nozzle portion 23 protrudes as described above, an impact force is applied to the nozzle portion 23 and an excessive force is applied in the rotation direction with respect to the operation button 20. Is considered to work. That is, a predetermined or more rotational force may act on the operation button 20 around the center line A of the discharge pipe 13, and in this embodiment, when an excessive rotational force in the left direction acts, the operation button The left side contact surface 24a of 20 is in contact with and supported by the left side button support wall portion 46 of the tubular cover 40. Further, when an excessive turning force in the right direction is applied, the right side contact surface 25a of the operation button 20 abuts on the right side button support wall portion 47 of the tubular cover 40 and is supported. Since the left contact surface 24a, the right contact surface 25a, the left button support wall portion 46, and the right button support wall portion 47 all extend in the direction of the center line A of the discharge pipe 13, a wide contact area is secured and a force is applied. It will act in a dispersed manner. As a result, damage to each part can be suppressed. In particular, the operation button 20 can suppress deformation and damage of the left guided portion 24b and the right guided portion 25b, and can also suppress deformation and damage of the peripheral portions of the left guide opening 46a and the right guide opening 47a. It is possible to avoid deterioration of the operability of the.

Further, when a predetermined or more rotational force acts on the operation button 20 around the center line A of the discharge pipe 13, the outer surface of the nozzle portion 23 is covered with the left nozzle support wall portion 48 and the right nozzle support wall portion of the tubular cover 40. Can be supported by 49. As a result, the turning power can be distributed to the nozzle portion 23 as well, so that damage to each portion can be suppressed.

The above embodiments are merely exemplary in all respects and should not be construed in a limited way. Further, all modifications and modifications belonging to the equivalent scope of the claims are within the scope of the present invention.

As described above, the container with an operation button according to the present invention can contain, for example, a pest repellent, an insecticide, a fragrance, a deodorant, a disinfectant, and the like.
