[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a fluid dispenser having a discharge mechanism operating on the principle of a pump.

2. Description of the Related Art Among dispensers having a discharge mechanism operating on the principle of a pump, a dispenser having a floating bottom for a viscous fluid and a bottom rising with decreasing contents. The thing is configured such that the pump cylinder part is partitioned by walls conforming to the shape of the floating bottom, leaving a closed space around the cylinder above it. Therefore, in the case where the lid is a fixed fitting type, when the pump-type discharge mechanism is mounted on the container, there is a disadvantage that air is trapped and the pressure in the closed space increases. The present invention aims to remedy this drawback.

[0002]

The present invention has a discharge mechanism that operates on the principle of a pump and has a piston-type free bottom and a fixed-fitting lid body, and has a head space separated from the content receiving portion. In the fluid dispensing container, at least one air passage groove is provided outside the mouth of the container neck so that compressed air does not remain in the head space when the discharge mechanism is inserted and the lid is applied. Is provided.

FIG. 1 is an elevational sectional view of a dispenser according to one embodiment of the present invention. The dispenser comprises a container body 10, a pump-type discharge mechanism 20, a floating bottom 30, an outer bottom 40, and a fixed fitting lid 50. The discharge mechanism (pump) 20 is supported by a gasket 60 and a neck of the container body. It is housed inside and is fixed by the fitting and fixing type lid 50. In this case, the contents are above the inlet 22 of the pump of the container, i.e.
A collar member 100 is used to block between the lower part 21 of the pump and the neck of the container so as not to enter. Normally,
After the collar member is mounted on the container, the discharge mechanism is mounted, and the lid holding the discharger is mounted. However, if the lid is mounted without care, in this case, the lid holding the discharge mechanism 20 and the gasket 60 is closed by the container opening. It is fixed by the engagement of the rib 12a provided on the part 12 and the rib 50a provided on the inner wall of the lid.

[0004] If this mounting is performed without care, the pressure in the neck portion 11 of the container will increase, and air may enter the container body (contents) side and cause inconvenience. In order to prevent this, the dispenser of the present invention, as shown in FIG.
At least one air passage 12b is provided outside the container opening 12. Due to this passage, even if the lid 50 is installed without care, air is not trapped until the gasket 60 contacts the bead 12c on the upper surface of the container mouth at the last moment.
