Pump type foam discharge container

Abstract

A pump type foam discharge container wherein an air suction opening capable of sucking a large amount of the outside air is provided so that water is reliably prevented from entering the container and so that foam is prevented from being sucked from the air suction opening. An air suction opening (45) is open on the side opposite the discharge opening (43) of a nozzle body (4). The air suction opening (45) is made to communicate through a communication hole (46) with an air flow path located between an inner tube section (41) and an outer tube section (42). A skirt-like cover section (47) hanging down from the outer edge of the top of the nozzle body (4) is formed so as to extend further downward than the air suction opening (45). At least one or more pairs of partition wall sections (49) for separating and isolating inner spaces of the skirt-like cover section (47) (which are space portions between the inner side of the cover section (47) and the outer tube section (42)) from each other in the circumferential direction of the nozzle body are provided in such a manner that each of the pairs is arranged on both sides of the air suction opening (45) relative to the circumferential direction of the nozzle body (4).

Description

technical field [0001] The present invention relates to a pump-type foam discharge container in which a nozzle body protruding upward from a cover of the container is formed as a downward pressure head, and the nozzle body is moved up and down by repeatedly performing a downward pressure operation and a pressure release operation on it. Move, thereby forming the content liquid contained in the container into a foam state, and discharge it from the discharge port of the nozzle body, especially related to a pump type foam discharge container in which a suction port for sucking in external air is provided on a part of the nozzle body . Background technique [0002] Liquids such as shampoo, hand soap, body soap, facial cleanser, hairdresser, shaving lotion, and bathtub cleanser are sometimes used in foam form. Conventionally, various containers for forming and discharging such liquid cleansers in foam have been developed, and these containers have been commercialized. This con...

Problems solved by technology

[0006] However, in the above-mentioned structure described in Japanese Patent Application Laid-Open No. 2007-275777, since the suction port (outside air inlet) is formed in the outer cylinder portion (skirt cover) of the nozzle body (foam ejector), for example, when When the container is in an overturned state, or when the container is held obliquely downward, there is a concern that the water adhering to the outer peripheral surface of the outer cylinder (skirt) will flow along the outer peripheral surface without being hindered by the defensive wall. Arrives near the suction port (external air inlet), and finally enters the container from the suction port (external air inlet)

[0007] In addition, when external water intrudes into the container, there is usually a concern that the sliding properties of the piston body may deteriorate due to washing away the lubricant such as silicon coated on the cylinder part, or that the liquid contained in the container may be mixed. (liquid cleaning agent), the color and fragrance of the content liquid will change

Furthermore, when a lot of water accumulates in the air chamber divided by the cylinder body and the piston body, since the ratio of the content liquid and air sent into the mixing chamber is different from that at the beginning of use, it is worried that the foam quality will be different from the designed foam quality.

Or, because most of the water intruded into the container is polluted, it will accumulate in the inside of the air tank and be prone to mold. In the case of mold, the musty smell will be sent into the mixing chamber by suction, which may cause discharge. The problem that the aroma of the foam becomes worse

[0008] As mentioned above, although various improvements have been made in the past to prevent water from entering the interior of the container from the suction port for sucking in external air, in fact, the foam discharge container is used in a variety of ways, and it is impossible to reliably prevent water and foam from entering the inside of the container. intrusion or inhalation
