Description

  The present invention relates to a foam discharge container for discharging a content liquid in a container body into a foam shape.

As such a foam discharge container, what is shown by patent document 1, for example is disclosed. This foam discharge container mixes air and the liquid in the container in the gas-liquid mixing chamber by pushing down the pump head, and generates bubbles by passing the mixture through a net (foaming member) in a mixed state. Is discharged from the discharge hole of the pump head.
This foam discharge container is provided with an air cylinder for sending air into the gas-liquid mixing chamber and a liquid cylinder for sending the content liquid into the gas-liquid mixing chamber, and is slidably disposed inside the air cylinder. In addition, it is necessary to press the air piston and the liquid piston arranged so as to be slidable inside the liquid cylinder at a time.

On the other hand, as a discharge container for moving the liquid piston with a small pressing force to discharge the content liquid, for example, one disclosed in Patent Document 2 has been proposed. The discharge container includes a lever member that is swingably supported, and an operation lever that can be hooked with a fingertip is provided at a tip of the lever member. It is a so-called trigger type discharge container that pushes down the liquid piston, and is known to have excellent operability because it can discharge the content liquid while holding the container body with one hand.

  By the way, in a foam discharge container that mixes air and the liquid in the container and discharges it in the form of foam, it is necessary to press the piston for air and the piston for liquid at a time to discharge the foam. A large force is required to press the pressure, and there is a possibility that bubbles cannot be discharged to a user having a weak force.

  Further, in the trigger type discharge container described in Patent Document 2, generally, the lever member and the discharge nozzle are integrally formed so that the discharge direction of the discharge nozzle and the swinging direction of the lever member substantially coincide. It is configured. Therefore, when changing the foam discharge direction, the direction of the trigger-type discharge container as a whole must be changed, and the swinging direction of the lever member (operating direction of the operating lever) must also be changed. Therefore, it may be difficult to swing the lever member, and handling is inconvenient.

  The present invention has been made in view of the above-described circumstances, and is capable of reliably discharging bubbles with a small force, easily changing the discharge direction of bubbles, and easily discharging bubbles. The purpose is to provide a container.

According to the foam discharge container having this configuration, the operating cylinder linked to the air piston of the air cylinder and the liquid piston of the liquid cylinder is disposed, and the lever cylinder that drives the operating cylinder is provided. Therefore, the air piston and the liquid piston can be pushed down with a relatively small force to transfer the air and the content liquid to the gas-liquid mixing chamber. Therefore, even a weak user can discharge bubbles.
In addition, since the foam discharge nozzle is mounted on the upper end portion of the operating cylinder so as to be rotatable about the central axis, the foam discharge nozzle is rotated to change the foam without changing the operation direction of the lever member. The discharge direction can be changed, and the handleability can be greatly improved.

  Here, you may arrange | position the discharge hole of the said foam discharge nozzle toward diagonally upward. In this case, the foam discharge nozzle is disposed so as to extend radially outward with the central axis as a center, and the foam discharge nozzle can be rotated around the central axis with a small force. Further, since the discharge hole is disposed obliquely upward, the discharge hole and the operating cylinder are smoothly connected, and bubbles supplied via the operating cylinder are smoothly discharged from the discharge hole. can do.

  Further, the lever member may be provided with an operation part that operates to hang a finger and pull the lever member, and the operation part may be provided with an extending member whose length is expanded and contracted. In this case, the length of the operation unit is increased, and the operability is further improved.

It will leave | separate from the connection shaft part 61. Therefore, the distance between the portion (action point) to be operated with a finger and the fulcrum increases, and the lever member 62 can be operated with a smaller force.

  Further, an edge is formed on the peripheral edge of the opening end of the discharge port 55 arranged at the tip of the foam discharge nozzle 50 so that the outer peripheral surface gradually approaches the inner peripheral surface toward the open end and the wall thickness is reduced. As a result, bubbles do not accumulate largely at the peripheral edge of the opening end.
