As shown in FIG. 1, a discharge container 1 according to one embodiment of the present invention includes a container body 10 and a discharge cap 20. As shown in FIG.

The container body 10 is, for example, a blow-molded product made of synthetic resin such as polyethylene, and includes a mouth portion 11 and a body portion 12 .

The mouth portion 11 has a cylindrical shape centered on the axis O, and a male thread 11a is integrally provided on the outer peripheral surface thereof. The trunk portion 12 is integrally connected to the lower end of the mouth portion 11 . The trunk portion 12 can contain a foaming liquid, such as a liquid detergent or a hair styling agent, as a content liquid.

The discharge cap 20 discharges the content liquid contained in the body portion 12 to the outside when the body portion 12 of the container body 10 is squeezed (pressed). In the present embodiment, the discharge cap 20 is a foam discharge cap that mixes the content liquid contained in the body portion 12 with air, forms a foam, and discharges the foam to the outside.

As shown in FIG. 2, the discharge cap 20 has a mounting cylinder portion 21, and a female thread 21a provided on the inner peripheral surface of the mounting cylinder portion 21 is screwed to a male thread 11a of the mouth portion 11, thereby closing the mouth. It is detachably attached to the portion 11 . A ceiling wall portion 22 of the discharge cap 20 is provided with a nozzle 23 extending laterally with respect to the axis O, and the tip of the nozzle 23 serves as a discharge port 24 for the content liquid. A tubular portion 25 is fixed to the lower surface of the ceiling wall portion 22 , and a lower member 26 is fixed to the lower end of the tubular portion 25 . A pipe 27 is connected to the lower end of the lower member 26 to introduce the liquid contained in the container body 10 into the tubular portion 25 . Further, the lower member 26 is provided with an air introduction port 26a for introducing the air inside the container body 10 into the cylindrical portion 25 . A mixing chamber 25a for mixing the liquid introduced from the pipe 27 and the air introduced from the air inlet port 26a is provided inside the tubular portion 25, and the mixing chamber 25a and the nozzle 23 are interposed therebetween. , two mesh members 28 are arranged. An outside air introduction port 23 a is provided at the rear end of the nozzle 23 , and the nozzle 23 does not pass through the cylindrical portion 25 and is connected to the interior of the container body 10 also by the outside air introduction port 23 a. The outside air inlet 23a is operated to allow air or content liquid to flow into the interior of the container body 10 from the nozzle 23 and to prevent air or content liquid from flowing out from the interior of the container body 10 to the nozzle 23. A check valve 29 is provided.

When the barrel portion 12 is squeezed, the internal space of the barrel portion 12 is pressurized, thereby causing the liquid contained inside the barrel portion 12 to flow through the pipe 27 into the mixing chamber 25a inside the cylindrical portion 25. At the same time, the air inside the body portion 12 is introduced from the air inlet port 26a into the mixing chamber 25a inside the cylindrical portion 25, and mixed in the mixing chamber 25a. The mixture is bubbled through two mesh members 28 and sent to the nozzle 23 , and is discharged to the outside from the outlet 24 in the form of a bubble. When the squeezing of the barrel 12 is released, the pressure inside the barrel 12 is reduced, and the outside air enters the container main body 10 through the outside air inlet 23a together with the foamy liquid remaining in the nozzle 23. returned.

As shown in FIG. 1, in the discharge container 1 of this embodiment, the body 12 is composed of a body 31 and a body 31 in order to facilitate the squeezing operation of the body 12 when discharging the content liquid. It is configured to have a lever portion 32 and a bellows portion 33 .

The barrel main body 31 is a bottle-shaped portion having a storage space for storing most of the content liquid, and is integrally connected to the lower end of the mouth portion 11 .

In this embodiment, the trunk main body 31 has a neck portion 31a on the mouth portion 11 side which is narrower than the bottom portion 13 side of the container main body 10 (the width toward the side in the front view shown in FIG. 1). It has a shape. A portion of the body portion body 31 below the neck portion 31 a bulges out toward the side on the same side as the nozzle 23 .

The lever portion 32 branches from the upper end portion of the body portion main body 31 to the same side as the nozzle 23 and extends obliquely downward. One end (upper end) of the lever portion 32 is integrally connected to the trunk portion main body 31 , and the lever portion 32 can swing with respect to the trunk portion main body 31 by elastically deforming a fulcrum portion 32a which is connected to the trunk portion main body 31 . ing.

In this embodiment, the lever portion 32 is a portion that protrudes toward the side of the neck portion 31a of the trunk portion main body 31, that is, the same side as the nozzle 23 below the neck portion 31a of the trunk portion main body 31. is placed above. Further, the lever portion 32 is arranged on the same side of the axis O as the discharge port 24 .

The bellows portion 33 is integrally provided between the body portion main body 31 and the lever portion 32 . More specifically, the bellows portion 33 is integrally connected to the body portion main body 31 on one end side in the expansion/contraction direction, and is integrally connected to the lever portion 32 on the other end side in the expansion/contraction direction. The bellows portion 33 is configured to expand and contract when the lever portion 32 swings with respect to the body portion main body 31 .

The internal space of the trunk main body 31, the internal space of the lever portion 32, and the internal space of the bellows portion 33 communicate with each other.

As shown in FIG. 3, the discharge container 1 of the present embodiment having the above configuration is pulled by the user, and when the lever portion 32 swings about the fulcrum portion 32a in the direction of approaching the body portion main body 31, The bellows portion 33 is compressed and deformed, thereby squeezing the body portion 12 so that the internal space is pressurized, and the content liquid stored in the body portion 12 is discharged from the discharge port 24 of the discharge cap 20 in the form of foam. be done.

At this time, the user can pull the lever portion 32 by gripping the lever portion 32 by gripping the body portion main body 31 with a hand and pulling the lever portion 32 with a finger. Therefore, it is possible to squeeze the body portion 12 more easily than in a discharge container in which the body portion 12 is sandwiched between the thumb and other fingers and the body portion 12 is squeezed by a pinch force. In addition, since the easily deformable bellows portion 33 is provided between the trunk portion main body 31 and the lever portion 32, the trunk portion 12 having the bellows portion 33 can be squeezed more easily by pulling the lever portion 32. be able to. In addition, the lever portion 32 can be pivoted with a smaller force due to the boosting action of the lever portion 32 based on the principle of leverage, so that the body portion 12 can be squeezed with an even smaller force. Therefore, according to the discharge container 1 of the present embodiment, even a user with relatively weak hand force such as an elderly person can grasp the trunk main body 31 and pull the lever portion 32 to operate the lever portion 32. Discharge operation of the content liquid from the discharge container 1 can be easily performed.

In this embodiment, the trunk body 31 has a neck portion 31a on the side of the mouth portion 11, the width of which is narrower in the direction along the side than the side of the bottom portion 13, and a lever portion on the side of the neck portion 31a. 32 are arranged, so that the user can hold the neck 31a with his hand and put his finger on the lever 32 when discharging the content liquid, so that the container body 10 can be more easily gripped. At the same time, the lever portion 32 can be made easier to pull. With this configuration, the operation of discharging the content liquid from the discharge container 1 can be performed more easily. Furthermore, the discharge operability of the discharge container 1 can be further enhanced by enabling the body 31 to be stably gripped by hand while ensuring the internal capacity of the body 31 .

Furthermore, in this embodiment, the container body 10 is a blow-molded product, so that the container body 10 having the above configuration can be manufactured easily and inexpensively by blow molding.

After the content liquid is discharged, when the pulling operation of the lever portion 32 is released, the elastic force of the bellows portion 33 causes the lever portion 32 and the bellows portion 33 to automatically return to their original positions or shapes. As described above, according to the discharge container 1 of the present embodiment, the elastic force of the bellows portion 33 allows the squeezed barrel portion 12 to be restored to its original shape more quickly and reliably. Therefore, the discharge operability of the discharge container 1 can be further improved.

It goes without saying that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.

For example, in the above-described embodiment, the container body 10 has a shape in which the trunk body 31 has the neck portion 31a. The shape can be changed in various ways, such as a shape in which the portion 33 protrudes laterally from the body portion main body 31 .

Further, the discharge cap 20 is not limited to the foam discharge cap described above, and is attached to the mouth portion 11 of the container body 10 and discharges the content liquid from the discharge port 24 when the body portion 12 is squeezed. Various structures can be used as long as they can be used, such as a structure that discharges the content liquid from the discharge port 24 as it is.

Furthermore, the content liquid contained in the container body 10 is not limited to liquids that form foams such as liquid detergents and hair styling products, and may be liquids that do not liquefy.
