Description

  The present invention relates to an outside air introduction mechanism for a discharge container, and more particularly to an outside air introduction mechanism for a discharge container for introducing outside air into a container body as liquid is sucked by a liquid ejector.

  Conventionally, various discharge containers are known in which a liquid discharge device such as a pump device or a trigger device is attached to a mouth portion of a container main body that contains a liquid via a cap portion. In these discharge containers, operation parts such as a pump head and a trigger lever are operated against an elastic biasing force by an elastic member provided in the liquid discharger, for example, by sliding a piston in a cylinder to The liquid is discharged in a liquid, mist, foam or the like state from the nozzle portion of the liquid discharger while opening the valve body in the path. Further, in these discharge containers, when the operation unit such as the pump head or the trigger lever is returned to the original position by the elastic biasing force, for example, the liquid is discharged from the container main body while opening the valve body in the suction path. To be inhaled.

When liquid is sucked into the liquid discharger from the container body, the inside of the container body becomes negative pressure, so outside air is introduced into the container body so that the negative pressure state is eliminated in these discharge containers. There is a need to. Therefore, an outside air introduction path is provided for introducing outside air into the container body as the liquid is sucked from the container body into the liquid ejector. In addition, for example, various outside air introduction mechanisms have been developed that prevent the liquid in the container body from leaking through the outside air introduction path when the discharge container falls over when the container is not used (for example, Patent Document 1). , Patent Document 2 and Patent Document 3).

The container 10 has a structure in which the air hole 25a of the ventilation sleeve 25 is closed to block the outside air introduction hole 15 from the outside air when the air 15 is communicated with the outside air and the liquid is not allowed to be discharged. By switching to a state in which the liquid cannot be discharged when not in use (see FIG. 4), it is possible to more reliably avoid liquid leakage through the outside air introduction hole 15.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the inner ring does not necessarily have to be provided on the inner surface of the top surface portion of the cap portion, and the elastic annular packing member does not necessarily have to be attached to the portion between the peripheral wall portion of the cap portion and the inner ring. In addition, the liquid ejector attached to the neck of the container body via the cap portion does not necessarily need to be a pump device, and can eject liquid by operating against the elastic biasing force of the elastic member. Other various types of liquid ejectors such as a push-down type, a pull-up type, and a pull-in type may also be used. The outside air introduction mechanism of the present invention can also be adopted for a discharge container to which a liquid discharger of bellows type, dropper type, diaphragm type, trigger type or the like is attached.
