Description

  The present invention relates to a liquid dispensing container, and more particularly to a liquid dispensing container capable of quantifying and dispensing a liquid content from a dispensing outlet when a container body trunk is squeezed.

  A container main body filled with a content liquid, a cap main body provided with a pouring cylinder attached to a mouth tube portion of the container main body, an inner cylinder mounted inside the cap main body and mounted in the container main body In the liquid dispensing container, the squeeze of the body of the container body causes the content liquid to be poured out from the spout of the cap body, and the inside of the deformed body is in contact with the outer periphery of the internal cylinder to prevent squeeze. Thus, the dispensing of the content liquid is stopped, and a liquid dispensing container capable of quantitatively dispensing the content liquid with a single squeeze operation has been conventionally known.

In addition, by attaching one end of a curved tube member whose both ends are directed upward to the lower end of the dispensing tube and making the curved tube member a flow channel tube, the container can be placed on its side as long as the body of the container body is not squeezed. A liquid dispensing container that prevents the content liquid from leaking even if it is turned upside down is conventionally known (for example, see Patent Document 1).
JP 2002-68245 A

  In the conventional container described in Patent Document 1, the inside of the container becomes negative pressure due to the restoring force of the container body when the body part is pushed in, and the liquid remaining in the spout and the curved tube member is sucked in. And put it back in the container.

However, since air is also sucked in together with the remaining liquid, the liquid is agitated and before the liquid completely returns to the container, the air first enters the container, the suction by the container is finished, and the middle of the curved pipe member Liquid may remain.
For this reason, when the container is turned upside down again, before the body portion of the container body is squeezed, there is a problem that the remaining liquid flows out and stains the outside.

  Further, when the container is tilted, there is a problem that the liquid is pushed into the bending tube member due to the water hammer phenomenon of the content liquid, and the accumulated liquid flows outside along the inner periphery of the bending tube member.

  An object of the present invention is to solve the above-mentioned problems, and as long as the body portion of the container body is not squeezed, the liquid injection can be prevented from flowing out even if the container is tilted sideways or upside down. The purpose is to provide a discharge container.

  In order to solve the above-mentioned problems, the present invention provides a container body having a flexible barrel as a liquid dispensing container, a cap body mounted on a mouth tube portion of the container body, and a cap body. In a liquid dispensing container comprising a suction cylinder member attached to the lower part of the provided extraction cylinder, the suction cylinder member is formed so that both ends thereof are substantially directed upward, and a small-diameter channel is provided in the middle. The structure characterized by this is adopted.

  As a specific example of the suction cylinder member, the suction cylinder member is attached to the connecting part attached to the lower part of the extraction cylinder of the cap body, the curved cylinder part attached to the connection part, and the distal end part of the curved cylinder part. The suction tube portion includes a lower tube extending downward, and a horizontal tube extending laterally from the lower portion of the lower tube via the curve portion, A small-diameter engaging cylinder that extends in the horizontal direction and a suction cylinder that extends upward from the small-diameter engaging cylinder via the bending portion. The inner circumference adopts a configuration characterized in that it is a small-diameter channel having a smaller diameter than the inner diameter of the other cylinder of the curved suction cylinder member.

  As another embodiment of the suction cylinder member, the suction cylinder member is formed with a connection part attached to the lower part of the extraction cylinder of the cap body, and attached to the connection part, with the middle curved so that both ends face upward. A configuration is provided in which a curved suction cylinder portion is provided, and a small-diameter channel having a smaller diameter is provided on the inner periphery of the curved suction cylinder portion as compared with the inner diameters of other tubes.

  As an example of the connecting portion, the connecting portion includes an upper engaging tube that engages with an engaging portion of the extraction tube of the cap body, a bottom wall formed at the lower end of the upper engaging tube, and a lower surface of the bottom wall. A configuration characterized by comprising an engaging cylinder and having a small-diameter channel provided at the center of the bottom wall is adopted.

  As an example of the resistance wall, a structure is characterized in that a flow path resistance member having a resistance wall that allows liquid to pass but is provided at the tip of the suction cylinder portion of the suction cylinder member is provided. Is adopted.

  A container body having a flexible body, a cap body mounted on a mouth tube portion of the container body, and a suction tube member mounted on a lower portion of an extraction tube disposed on the cap body. In the liquid dispensing container, the suction cylinder member is formed so that both ends thereof are substantially directed upward, and a small-diameter channel is provided in the middle, so even if liquid remains in the suction cylinder member, Even if the liquid flow is stopped by the capillary phenomenon and the container is inverted, the liquid can be prevented from flowing out of the container unless the body portion of the container body is pressed.

In addition, although the liquid can pass through the tip of the suction cylinder part of the suction cylinder member, since the flow path resistance member provided with the resistance wall that becomes the resistance of the liquid flow is mounted, the resistance wall of the flow path resistance member is It becomes resistance of the flow of the liquid of the flow path of a suction cylinder part, and it sucks slowly with respect to the negative pressure in a container.
