Thus, the connecting body 13 is formed, and the connecting body is fitted into the elliptic cylinder 14. Further, an upward U-shaped support portion 15 is formed at the center of the connecting plate 12.

  Reference numeral 20 denotes a cylindrical case, and a bottom plate 22 is attached to the lower inner surface of an elliptical peripheral wall 21, and a peripheral wall portion below the bottom plate is fitted into the outer surface of the connecting cylinder 10 so that it cannot be pulled out. Stem insertion holes 23 are formed in the left and right portions of the bottom plate 22, and the upper portion of the stem 2 reaches above the bottom plate 22 through the holes. Notches 24 are formed in both front and rear portions of the peripheral wall 21. The notches located at the front cause the nozzle body, which will be described later, to protrude, and the notches located at the rear move the operation plate, which will be described later, up and down. For each.

  Reference numeral 30 denotes a blocking member integrated with the cylindrical case, and a pair of left and right engaging columns 31 are erected at a predetermined distance from the central portion of the bottom plate 22 between the pair of left and right stems 2. An upward step 32 is formed on the lower outer surface of each engagement column.

  Reference numeral 40 denotes a nozzle head, in which a lower part of a fitting cylinder 42 suspended from the peripheral edge of the through hole on the bottom surface with a through hole of the pair of left and right liquid chambers 41 is slidably fitted to the upper part of the stem 2. An intermediate portion in the vertical direction of the fitting cylinder 42 is formed in a small inner diameter portion 42 a, and a gap G is formed between the small inner diameter portion and the upper end of the stem 2. The lower ends of the pair of left and right liquid chambers 41 are connected to each other by a connecting plate 43, and a through hole 43a for inserting the pair of engaging columns 31 is formed at the center of the connecting plate. The nozzle head 40 is prevented from descending by the peripheral edge of the through hole 43a engaging the upward stepped portion 32.

From each liquid chamber 41, a nozzle 44 projects forward, and these nozzles are formed into an integral nozzle body 45 by integral molding. From the upper surface of the nozzle body, a sliding plate 46 that can be slidably fitted to a fitting portion of an operation member described later is erected, and a release member described later is guided from the upper surface of each liquid chamber 41. A guide plate 47 is erected.

  An operating member 50 is provided with a notch 52 at the rear part of the elliptical cylindrical part 51 fitted into the cylindrical case 30, and is provided as a hinge for the central part of the top plate 53 that closes the upper surface of the cylindrical part 51. An operation plate which can be turned in the vertical direction by providing a separation line 54 leaving a portion and providing a rear portion of the top plate portion surrounded by the separation line so as to be slidably fitted into the cutout portion 52. 55. A fitting portion 56 formed of a gap in the lower surface opening is formed on the inner surface of the front portion of the cylinder portion 51 and in the left-right direction, and a sliding plate 46 is fitted in the fitting portion so as to be movable up and down.

  Reference numeral 60 denotes a release member, which bulges the front-rear direction intermediate portion of the upper wall 62 that closes the upper surface of the elliptical peripheral wall 61 fitted in the cylinder portion 51 so as to be movable up and down and presses it against the lower surface of the operation plate 55. A pair of front and rear engaging plates 64 are vertically provided at a predetermined interval from the lower surface of the intermediate portion in the left-right direction of the pressing portion 63 while being formed in the pressing portion 63. The front and rear sides of the engagement plate form spring member receiving portions 65 described later.

The inner surface of the lower end portion of each engagement plate 64 is formed on an inclined surface 66, and both inclined surfaces are inclined so as to define an expanding space portion that expands downward when viewed from the left-right direction. The inclined surface 66 is formed so that the upper end of the engaging column 31 can be brought into contact with the inclined member when the release member is lowered, and the engaging column contacts the inclined surface and slides on the inclined surface. It can be inclined to the direction.

The lower ends of the left and right portions of the peripheral wall 61 are extended downward, and the extended portions are fitted to the front and rear surfaces of the liquid chamber 41 of the nozzle head so as to be movable up and down.

Reference numeral 70 denotes a spring member, which is formed of a coil spring. The coil spring is disposed so as to surround the engagement column 31 and the engagement plate 64, and has an upper end connected to the receiving portion 65 and a lower end connected to the nozzle head. The nozzle 43 is in contact with the plate 43 so as to be able to bias the nozzle head 40 downward.

Reference numeral 80 denotes an auxiliary spring member, which is formed of a coil spring. The coil spring is disposed so as to surround the fitting cylinder 42 through the stem insertion hole 23, and its upper end is a liquid chamber portion around the fitting cylinder 42. A plurality of drooping plates 41a that hang from the lower surface, and lower ends thereof are in contact with the upper surface of the aerosol container body, respectively, so that the nozzle head 40 can be urged upward.

Next, the operation will be described. In order to discharge from the nozzle head 40, the operation plate 55 may be pushed downward. Then, the release member 60 is lowered to compress the spring member 70, and the engagement plate 64 is lowered. The engagement plate is lowered and the inclined surface 66 engages with the upper end of the engagement column 31 to incline the pair of engagement columns inward (in a direction approaching each other), thereby increasing the distance between the engagement columns. The upper end portion of the engagement column 31 is fitted into the portion of the engagement plate 64 above the inclined surface 66.

  When the pair of engaging columns 31 are inclined inward in this way, the nozzle head 40 is disengaged from the upward stepped portion 32, but the spring member 70 is compressed and the spring force is accumulated until then. Therefore, the lowering speed of the nozzle head 40 is large, and therefore, both stems can be pushed down almost simultaneously even if the operation timing varies between the pair of stems 2. When the stem 2 is pushed down, the content in the container body 1 flows into the liquid chamber 41 through the small inner diameter portion 42 a and the through hole, and is further discharged from the nozzle 44.

When the pressing of the operation plate 55 is released after discharging, the downward biasing force of the spring member 70 is reduced, and the auxiliary spring member 80 biases the nozzle head 40 upward. As the head moves up, the engagement plate 64 is disengaged upward from the engagement column 31 and the engagement column is restored to the upright state. For this reason, when the nozzle head 40 reaches the height of the upward step portion 32, the upward step portion 32 engages with the nozzle head 40. In addition, since the gap G is formed between the upper end of the stem and the lower surface of the liquid chamber 41, even when the nozzle head is inclined with respect to the aerosol container body, this inclination can be absorbed. The stem does not descend in response to the inclination, and therefore discharge based on malfunction is prevented.

  As described above, in the present invention, since the stem 2 is pushed down in a state where the spring force of the spring member 70 that urges the nozzle head 40 downward is sufficiently accumulated, the operation start timing varies between the pair of stems. Although the pair of stems can be pushed down almost simultaneously, it is difficult to say that the purpose of simultaneously pushing down the stems is completely achieved.

That is, even if the biasing force to the nozzle head is sufficiently accumulated, if there is variation in the timing of disengagement of the nozzle head, for example, blocking members for preventing the nozzle head from descending are provided on both the left and right sides of the nozzle head. If the timing of the engagement / disengagement of the nozzle head is different on the left and right, especially if this timing shift is not merely a coincidence but due to an essential factor such as accuracy, the frequency is very high. This is because it has been experimentally found that the nozzle head descends in a state tilted to the left and right.

When the nozzle head is lowered in a tilted state in this way, it is difficult to push down the pair of stems at the same time even if the nozzle head descending speed is high. In the present invention, since the blocking member 30 is provided in the central portion between the pair of stems, the nozzle head 40 may tilt and descend even if the nozzle head is engaged with the blocking member at two locations (upward stepped portion 32). It has been experimentally found that there is almost no.

Next, another embodiment will be described. In the above description, the upward stepped portion 32 is formed on the outer surface of the pair of engaging columns 31 constituting the blocking member. However, the present invention is not limited to this, and the stepped portion 32 may be formed on the inner surface of the pair of engaging columns. In this case, a pair of through holes 43a are formed in the central part of the connecting plate 43 that connects the liquid chambers 41 to each other, and the peripheral parts of the through holes 43a of the nozzle head are inserted by inserting each engaging column into a separate through hole. While engaging with the upward step part 32, as shown in FIG. 7, a pair of engaging plate 64 which comprises the releasing member 60 is fitted in between a pair of engaging columns 31, and a pair of engaging column is outward ( The nozzle head is engaged and disengaged by inclining in a direction away from each other.

  The number of the engagement pillars 31 may be one instead of a pair. In this case, the engagement position of the nozzle head with respect to the engagement column, that is, the number of upward stepped portions is set so that the engagement column is inclined left or right, and the number of engagement plates is also one. Thus, the engaging column is inclined to the left or right.

Further, in the above description, a coil spring is used as the spring member 70. However, the present invention is not limited to this, and it is also possible to employ a curved plate spring that protrudes upward. In this case, both ends of the plate spring are placed on the upper surface of the liquid chamber 41 of the nozzle head, and the release member 60 is brought into contact with the top of the plate spring. The material of the spring member is not particularly limited, but synthetic resin is preferable.

  FIG. 8 shows a third embodiment. In the above description, a coil spring is used as the auxiliary spring member 80. However, the present invention is not limited to this, and a plate spring can be integrally projected from the cylindrical case 20 and engaged with the nozzle head 40 as shown in FIG. .

  Specifically, a bent plate spring 90 that protrudes downward from the bottom plate 22 portion around the stem insertion hole 23 formed in the bottom plate 22 of the cylindrical case 20 is integrally raised and the upper end thereof is fitted into the fitting cylinder. 42 is brought into contact with the lower ends of a plurality of drooping plates 41a that hang from the lower surface of the liquid chamber 41 portion around 42. The pair of leaf springs 90 are erected in the front-rear direction so that the fitting cylinder 42 is clamped. Since the cylindrical case 20 is made of synthetic resin, the leaf spring 90 is also made of the same material.

With the above configuration, when the pressing of the operation plate 55 is released after ejection, the downward biasing force of the spring member 70 is reduced and the leaf spring 90 biases the nozzle head 40 upward. This raises the nozzle head.

Although the auxiliary spring member 80 is provided in the above, it can be omitted.
In this case, the biasing force by the spring member 70 is adjusted so that the nozzle head 40 after the stem is pushed down can be lifted by the lifting force of the stem alone.

  The present invention can be used in the field of a two-liquid discharge container capable of simultaneously discharging two kinds of liquids.
