Embodiment Construction

[0043] The present invention will be described in more detail through the drawings of preferred embodiments below.

[0044] Such as figure 1 As shown, the support cap 20 can be fixed on the mouth and neck portion 11 of the bottle-shaped container 10 filled with liquid content through threads, and can be disassembled at any time. A dual pressure pump 30 is installed in the support cap 20 to draw, pressurize and pressure-feed the content in the container 10 and the outside air respectively.

[0045] The pressure pump 30 has a cylinder 31 that fits with the undercut of the support cap 20 and hangs below the support cap 20, and consists of a small diameter cylindrical part 31a and a large diameter cylindrical part connected in series with the small diameter cylindrical part 31b composition. The small-diameter cylindrical portion 31a includes an introduction port 31h to which a pipe 31p for sucking up the contents inside the container 10 is connected.

[0046] The small-diameter c...

Abstract

A foamer dispenser, comprising a double pump (30) individually sucking, pressurizing, and force-feeding contents in a container and the outside air, a head (40) forming a confluence space (R) for connecting the out-side passages (P3) and (P4) of the pump (30) and having a passage (42) for joining the space (R) to an injection end (41) led to the outside, and a foaming element (50) installed in the passage (42) of the head (40). The foaming element (50) further comprises a jet ring (51) having an in-side opening (H) with an opening area smaller than that of the passage (42) of the head (40) and a cylindrical body (51b) with an opening area larger than that of the opening (H) and joined to the passage (42) and meshes (52a) installed facing the opening (H), brought into contact with the contents from the opening (H), and having a large number of fine holes allowing a part of the contents to pass therethrough. The mesh (52a) comprises an opening having a diameter (D2) of 2.0 to 3.5 times, preferably 2.2 to 3.2 times, the diameter (D1) of the jet ring at the in-side opening.

Description

technical field [0001] The present invention relates to a blowing agent sprayer for spraying a foam mixture of air and liquid content. Background technique [0002] On containers filled with contents such as facial cleanser and hair styling agent, foaming agent sprayers are usually installed on the containers in order to avoid foaming components of liquid contents and to be more convenient to use. The main function of this blowing agent sprayer is to make the contents in the container foam directly for spraying. As an example, such a blowing agent sprayer is generally fixedly installed on the mouth and neck of the container as a base cap. A cylinder is housed in the support cap. In the cylinder, there is a piston that draws the content, pressurizes it, and pressurizes it; in addition, there is a piston (air piston) that sucks in external air, pressurizes it, and escorts it. The two pistons are concentrically arranged in-line to form a double pressure pump. The pressing c...
