Description

  The present invention relates to a discharge container with a nozzle cap, and more particularly, to a discharge container with a nozzle cap that includes a container main body that contains a content liquid and a nozzle cap that is attached to the mouth of the container main body and includes a discharge nozzle portion.

  As a container with a nozzle cap consisting of a container body containing the content liquid and a nozzle cap provided with a discharge nozzle portion, for example, a squeeze foamer container or a squeeze-type double peeling container holds and presses the container body, By pressurizing the inside of the container main body, the content liquid is sent to the discharge nozzle portion, and the content liquid is discharged from the discharge port at the tip in the form of foam, spray or liquid.

  In a discharge container with a nozzle cap that discharges the content liquid to the discharge nozzle by pressurizing the inside of the container body, for example, when the pressure on the container body is released, the inside of the container body becomes negative pressure Along with this, by taking outside air into the inside of the container body through the outside air intake port, the container body that has been reduced in volume by pressing can be returned to its original shape. In addition, the outside air intake port that takes in outside air into the container body can be opened and closed by a valve mechanism so that the air inside does not flow out through the outside air intake port when the container body is pressed, for example. (For example, refer to Patent Document 1 and Patent Document 2).

The intake valve mechanism 15 for opening and closing the outside air intake port 14 by a simple structure and assembling process that is simply joined and integrated in a state is a part of a different part that is different from the resin material of the nozzle cap 12. Without using a separately formed valve member.

  Further, according to the discharge container 10 with the nozzle cap of the present embodiment, the porous member 22 is attached to the inside of the vertical discharge flow channel 16 from above with the main body part 12a and the lid part 12b being opened, An intake valve mechanism 15 for opening and closing the outside air intake port 14 is provided by joining and integrating the opened main body part 12a and lid part 12b in a closed state. As a result, it becomes possible to form the nozzle cap 12 having a squeeze foamer function that foams the content liquid and discharges it as foam while keeping the height lower, and the container can be easily made compact. In addition, the number of parts and the amount of resin to be used can be effectively reduced, and it can be formed at a lower cost.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, the discharge container with a nozzle cap of the present invention does not necessarily need to be a squeeze foamer container, and discharges the content liquid from the discharge nozzle part by pressing (squeezing) the container body such as a squeeze type double peeling container. Other squeeze containers may be used. Moreover, the discharge container with a nozzle cap of the present invention does not necessarily need to be a squeeze container that discharges the content liquid by pressing the container body, and the content sent by pressurizing the inside of the container body, such as a pump container. Other various discharge containers having a function of discharging the liquid from the discharge nozzle portion may be used.

  In addition, the lid part does not necessarily need to form the upper part of the part including the discharge nozzle part and the area where the outside air intake port opens, and only forms the upper part including the area where the outside air intake port opens. It may be what you do. Furthermore, the lid part does not necessarily have to be connected to the main body part via the hinge joint, and may be formed as a separate part from the main body part.

  Further, the valve part does not necessarily need to be cantilevered in the main body part, and may be a valve part provided with a large number of valve pieces by, for example, inserting a plurality of through slits radially from the center of the rubber plate. In this case, it is preferable to attach the rubber plate so that the center of the rubber plate (starting point of the radial through slit) coincides with the axial center of the cylindrical valve seat portion. For example, there is a method of fixing by sandwiching between a main body part and a lid part. A ball valve using a sphere made of resin or the like can also be used. For example, instead of the valve support piece, the ball valve is provided with a cylindrical body having an inner diameter larger than the outer diameter of the sphere on the main body part side, concentrically with the outside air intake, and the inner diameter near the upper and lower openings is set outside the sphere. The squeezing is gradually made smaller than the diameter so that the sphere does not come out of the cylindrical body. The sphere is normally arranged at the bottom of the cylindrical body by gravity, but the sphere moves up and down in the cylindrical body as the container body is pressed or released, and the outside air intake port is opened and closed. Done smoothly. When the sphere is in contact with the upper opening inside the cylindrical body by pressing the container body and the internal pressure, the dimensions of the sphere and the cylindrical body are set so that the outside air is blocked from the inside of the container body. On the other hand, when the pressure on the container body is released and the sphere comes into contact with the lower opening inside the cylindrical body, the dimensions of the sphere and the cylindrical body are set so that the outside air is not blocked from the inside of the container body. It is preferable.
