Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trigger-type ejection container in which a liquid contained in a container body is ejected from a nozzle by driving a pump by pulling an operating lever.

In the field of containers containing liquids such as various detergents, fragrances, cosmetics, etc., a trigger type is used in which a pump is driven by pulling an operation lever, and the liquid contained in the container body is ejected from a nozzle. Ejection containers are often used.

As such a trigger-type ejection container, for example, Patent Document 1 discloses that the side on which the nozzle is located and the side of the operating lever on which a finger is placed are the same, and the operating lever is operated in a state in which the nozzle is oriented away from the operator. It is shown to squirt the contents away from the operator when pulled forward.

On the other hand, according to the container disclosed in Patent Document 2, it is possible to eject the content liquid such as cosmetics toward the operator. Here, the container shown in Patent Document 2 has an operation lever provided above the container main body, and in a state in which the spout is directed toward the operator, the barrel of the container main body on the side where the spout is located is operated. The part is supported by the base of the thumb, and the forefinger is hooked on the operation lever to hold it. Then, by moving the finger hooked on the operating lever in an oblique downward direction, it is possible to squirt, for example, cosmetics onto one's own face or head.

By the way, when ejecting the content liquid from the container of Patent Document 2, the upper part of the container body near the operation lever is held. Therefore, it is difficult to squirt the contents of such a container into hard-to-reach places such as the back.

On the other hand, in such a container, if the operation lever is lengthened, the middle part and the lower part of the container body can be held, so it is considered that the content liquid can be easily ejected to the back and the like. However, as the operation lever becomes longer, even if the force applied during operation does not change, a large force is applied to the portion to which the force is transmitted by the operation lever, which may lead to problems such as breakage.

An object of the present invention is to solve such problems, and it is possible to easily eject the content liquid to places that are difficult to reach, such as the back, and to eliminate the factor of applying excessive force.

Further, the lower portion 4g of the operating portion is provided with a recessed portion 4h for preventing slippage of the finger when force is applied. Further, as shown in the cross-sectional view along AA in FIG. 1, the inner peripheral surface 4j of the operating portion lower portion 4g is formed to be curved in an arc shape. The shape of the inner peripheral surface 4j is formed so as to fit the outer peripheral surface of the cylindrical body portion 1b.

The cap body 5 has a cylindrical shape with a lid, a cap portion 5a covering the tip of the nozzle 3d, a rod-like connecting portion 5b connected to the cap portion 5a and directed to the vertical portion 3b of the stem 3a through the window hole 4c, and a connecting portion. 5b and interposed between the upper end portion of the mounting tube portion 2a and the lower end portion of the projection 3f. A connecting portion reinforcing wall 5d for reinforcing the connecting portion 5b is provided below the connecting portion 5b. In the example shown in FIG. 1, the connecting portion reinforcing wall 5d has an amount of protrusion that reaches the middle portion of the stopper 5c in the vertical direction, but as shown in FIG. may In addition, when increasing the amount of protrusion of the connecting portion reinforcing wall 5d from the state of FIG. 1, the length of the operating lever reinforcing portion 4d is shortened so as not to interfere with it. Here, as shown in FIG. 2B, the stopper 5c of this embodiment has a C-shape in bottom view, and is fitted and held by the vertical portion 3b of the stem 3a.

By the way, as shown in FIG. 1, a support wall inclined portion 2e is provided above the support wall 2c in the base 2 of this embodiment. Here, since the support wall inclined portion 2e extends from the upper end portion of the mounting cylinder portion 2a toward the window hole 4c, when the stopper 5c is inserted through the window hole 4c in attaching the cap body 5, the stopper 5c is It is guided between the upper end portion of the mounting tube portion 2a and the lower end portion of the protrusion 3f by the supporting wall inclined portion 2e. When the support wall inclined portion 2e is provided in this way, the stopper 5c can be guided, so that the cap body 5 can be attached more easily.

Since the nozzle 3d of the trigger-type ejection container configured in this way is covered with the cap portion 5a, it is possible to prevent dust or the like from adhering to the nozzle 3d even when it is not used for a long period of time. In addition, when the cap body 5 is attached, even if the operation lever 4 is touched, the stem 3a is not moved by the stopper 5c, so that the content liquid can be prevented from being ejected unintentionally.

In order to eject the contents of the container body 1 by means of this trigger-type ejection container, the cap body 5 is removed as shown in FIG. The other finger is placed in the recessed portion 4h of the operating lever 4 and held by one hand. By holding in this way, the nozzle 3d can be directed to hard-to-reach places such as the back. Then, when the hand is operated by clenching the holding hand, the operating lever 4 is pulled to push down the stem 3a, which in turn activates the pump built in the body 3, so that the liquid content is ejected to the back or the like. can be made

Here, as shown in FIG. 3, the operating lever 4 of the present embodiment has a swingable angle A1 about the shaft portion 2d of the operating lever 4 within a range (stem 3a is a range in which the engaging portion 3e can move without applying a load greater than the designed load to other members), and the swingable angle A2 around the shaft portion 2d in the engaging portion 3e is set to be less than that. ing. That is, although the operation lever 4 can be operated with a small force by increasing the length of the operation lever 4, if it is operated with a slightly strong force, a large force will be applied to the portion where the operation lever 4 acts, but the stem Since 3a does not move excessively, the pump connected to stem 3a is not adversely affected.

Further, the operating lever 4 of this embodiment is designed to press against the trunk portion 1b of the container body 1 as shown in FIG. As described above, the rigidity of the container body 1 is relatively high, so even if the operation lever 4 is pressed against it, the trunk portion 1b will not be greatly bent inward. That is, even if the operating lever 4 is gripped with a strong force, the swingable angle A1 about the shaft portion 2d of the operating lever 4 does not change significantly, so damage to the pump or the like can be effectively prevented. Further, the inner peripheral surface 4j of the operating lever 4, which presses against the outer peripheral surface of the body portion 1b, is formed in an arc so as to fit the outer peripheral surface of the body portion 1b as described above. The outer peripheral surface of the trunk portion 1b is in close contact with the entire surface. That is, since the operating lever 4 is less likely to slip laterally (to be twisted) with respect to the container body 1 when gripped with one hand, an excessive load is applied to the shaft portion 2d or the like supporting the operating lever 4 in a swingable manner. is prevented.

In the above-described embodiment, the inner peripheral surface 4j of the operating lever 4 is entirely pressed against the outer peripheral surface of the trunk portion 1b of the container body 1 to stop the operating lever 4. Protrusions may be provided on the inner peripheral surface 4j and the outer peripheral surface of the body portion 1b, and when the operating lever 4 is pulled, the operating lever 4 may be stopped by coming into contact with the other side. Also, such a function can be realized by using other parts. For example, like the base 2 shown in FIG. 4, an outer peripheral wall 2f that surrounds the mounting tube portion 2a and extends downward may be provided so that the operation lever 4 presses against the outer peripheral wall 2f. In the embodiment shown in FIG. 3, the swing angle A1 of the operating lever 4 about the shaft portion 2d is such that the inner peripheral surface 4j of the operating lever 4 fully presses against the outer peripheral surface of the body portion 1b. If the above-mentioned protrusions or the outer peripheral wall 2f are provided, the angle is the angle at the time when the operating lever 4 is stopped by these.

In addition, the trigger-type ejection container of this embodiment, for example, when applying the content liquid to one's face, supports the front of the upper part of the body part 1b (or the base 2) with the base of the thumb, and the operation lever 4 It is also possible to operate by applying a force to the upper portion 4f of the operation portion of . In this case, since the nozzle 3d is held nearer, it becomes easier to direct the nozzle 3d to the desired application area.

Next, a second embodiment of the trigger type ejection container according to the present invention will be described with reference to FIGS. 5 and 6. FIG. The trigger type ejection container of this embodiment has an operating lever 14 as shown in FIGS. 5 and 6 instead of the operating lever 4 shown in FIG.

The operating lever 14 has a side wall 14a having the same configuration as the side wall 4a described above. Although not shown, the side wall 14a also engages with the shaft portion 2d to hold the operating lever 14 on the base 2 so as to swing, and the engaging portion 3e to engage with the operating lever 14. is provided with a second concave portion that pushes down the stem 3a when the is pivoted with respect to the base 2. The operating lever 14 also includes an upwardly inclined portion 14b, a window hole 14c, and an operating lever reinforcing portion 14d having the same configurations as the upwardly inclined portion 4b, the window hole 4c, and the operating lever reinforcing portion 4d.

The operating portion 14e is composed of an operating portion upper portion 14f which is positioned above the stem 3a and extends downwardly and rearwardly, and an operating portion lower portion 14g which is bendably connected to the operating portion upper portion 14f. ing. In this embodiment, as shown in FIG. 6, the upper portion 14f of the operation portion and the lower portion 14g of the operation portion are connected via the hinge 14k. When the lower operating portion 14g, which has been bent as shown in FIG. 6, is extended, the lower operating portion 14g extends more inclined toward the trunk portion 1b than the upper operating portion 14f. Further, the extended lower portion 14g of the operating portion is held as illustrated by the projection 14m provided on the upper portion 14f of the operating portion entering and being caught by the hole portion 14n provided on the lower portion 14g of the operating portion. The lower portion 14g of the operating portion is also provided with a recessed portion 14h for preventing the finger from slipping when force is applied.

Also in the trigger-type ejection container of this embodiment, by pulling the operation lever 14 with the lower portion 14g of the operation portion extended, the content liquid can be ejected to a hard-to-reach place such as the back. Although illustration is omitted, in the trigger-type ejection container of this embodiment as well, the swingable angle of the operating lever 14 around the shaft portion 2d is within the allowable range when the stem 3a moves up and down. It is set to be less than the swingable angle of the portion 3e around the shaft portion 2d. Therefore, since the stem 3a does not move excessively, the pump connected to the stem 3a is not adversely affected. Further, as shown in FIG. 6, when the operation lever 14 is pulled, the portion that comes into contact with the operation lever 14 is the trunk portion 1b of the container body 1, which has relatively high rigidity, and the operation lever 14 can swing around the shaft portion 2d. Since the angle does not change greatly, it is possible to effectively prevent damage to the pump or the like.

In addition, the trigger-type ejection container of the present embodiment can eject the content liquid by applying force to the folded operation portion lower portion 14g even in a state where the operation portion lower portion 14g is folded as shown in FIG. . The operating portion upper portion 14f of the present embodiment is provided with a rib 14p that abuts against the operating portion lower portion 14g in a folded state. Therefore, when force is applied to the bent lower portion 14g of the operating portion, the upper portion 14f of the operating portion can be swung via the rib 14p without applying a large force to the hinge 14k. In addition, the operating portion lower portion 14g may be provided with grooves that are inserted into the ribs 14p when the operating portion lower portion 14g is folded. can.

Triggered squirt canisters according to the present invention can also be embodied in the embodiments shown in Figures 7-9. The trigger type ejection container of the third embodiment shown in these figures has an operating lever 24 in place of the operating lever 4 shown in FIG.

The operating lever 24 also has a side wall 24a having a structure similar to that of the side wall 4a described above. A recess and a second recess that engages with the engaging portion 3e and pushes down the stem 3a when the operating lever 24 is pivoted with respect to the base 2 are provided. The operating lever 24 also includes an upwardly inclined portion 24b, a window hole 24c, and an operating lever reinforcing portion 24d having the same configuration as the upwardly inclined portion 4b, the window hole 4c, and the operating lever reinforcing portion 4d.

The operation portion 24e is composed of an operation portion upper portion 24f that is positioned above the stem 3a and extends downwardly and rearwardly, and an operation portion lower portion 24g that can be attached to the operation portion upper portion 24f. . As shown in FIG. 7, in this embodiment, an operation portion upper portion 24f is provided with a mounting hole 24q, and an upper end portion of an operation portion lower portion 24g is provided with an L-shaped holding portion 24r that can pass through the mounting hole 24q. are provided. Further, an engaging convex portion 24s that protrudes inward in the left-right direction is provided on the inner side surface of the operating portion lower portion 24g. When the operating portion lower portion 24g is attached to the operating portion upper portion 24f, the holding portion 24r is passed through the attachment hole 24q from above downward and then slid rearward and downward to move the edge portion of the attaching hole 24q. can be hooked on Further, in this state, the engaging projection 24s is engaged with the lower end of the operating portion upper portion 24f as shown in the figure, so that the attached operating portion lower portion 24g does not easily slide upward. there is The lower portion 24g of the operating portion is also provided with a recessed portion 24h for preventing slippage of the finger when force is applied.

Also in the trigger-type ejection container of this embodiment, while supporting the front of the body portion 1b near the bottom portion 1a with the base of the thumb, the other fingers are held so as to be accommodated in the recessed portion 24h of the operating lever 24. The nozzle 3d can also be directed to hard-to-reach places such as the back. Then, by pulling the operating lever 24, the liquid content can be ejected. Also in the trigger-type ejection container of this embodiment, as in the previous embodiment, the swingable angle of the operating lever 24 around the shaft portion 2d is within the allowable range when the stem 3a moves up and down. It is set to be less than the swingable angle of the engaging portion 3e around the shaft portion 2d. Therefore, since the stem 3a does not move excessively, the pump connected to the stem 3a is not adversely affected. Also, when the operation lever 24 is pulled, the portion that comes into contact with the operation lever 24 is the trunk portion 1b of the container body 1, which has relatively high rigidity, as in the above-described embodiment. Since the movable angle does not change greatly, it is possible to effectively prevent damage to the pump or the like.

In addition, the trigger type ejection container of this embodiment is more compact before the operation part lower part 24g is attached. There is an advantage that it becomes easy to handle. As shown in FIG. 8, the unattached operating portion lower portion 24g can be held by the operating portion upper portion 24f so as to be sandwiched between the holding portion 24r and the engaging convex portion 24s. Alternatively, as shown in FIG. 9, a film F or the like may be wrapped around the container body 1 to hold it.

As described above, the present invention has been described by showing specific embodiments, but the trigger-type ejection container according to the present invention is not limited to the above-described embodiments, and various modifications are made within the scope of the claims. things are also included.
