JPH0840473A - Structure of liquid suction port for ejecting container - Google Patents

Abstract

PURPOSE:To make the ejecting possible through a eject orifice provided to a eject container with liquid sucked from a through hole provided to a weight through a flexible pipe spirally wound for sucking liquid at all times either in the case where the ejecting container is put upright or in the case where the ejecting is container fallen by a method wherein the weight is connected to an opening at the free end of the flexible spiral suction pipe for liquid. CONSTITUTION:A flexible spiral suction pipe 1 for liquid is fixed to a through hole 8 of a weight 7 with its straight part on the front end being prevented from projecting to the outside of the weight 7. Therefore, the suction port of the flexible spiral suction pipe 1 for liquid in the ejecting container 3 can be moved downward as the weight 7 moves, and thereby the suction port of the flexible spiral suction pipe 1 for liquid can be made available for sucking liquid, being put under the liquid surface at all times together with the weight 7 when the weight 7 is put under the liquid surface so long as the liquid is existent in the ejecting container 3. Then, the liquid in the ejecting container 3 can be sucked up to a valve and ejected with fail through the ejecting orifice.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid suction port structure for an injection device, and more particularly to a liquid suction port structure for a spiral liquid suction tube of an injection device, and more particularly, a spiral structure for a finger push button type injection device.

2. Description of the Related Art Conventionally, a variety of research and development have been made on a liquid absorption mechanism for an injection valve of a finger push button type injection device. Among them, a synthetic resin tube having an appropriate diameter is generally used as the liquid absorption tube. Came. Therefore, a liquid suction port structure has been used in which the opening portion at the lower end of the liquid suction tube can be located close to the bottom portion of the injection container. However, since the material of the liquid absorbing structure of the synthetic resin tube is relatively hard and cannot be bent, the finger push button type injection device is used in such a liquid absorbing structure of the synthetic resin tube. In the case of the above, when it is used upright, it can be used as an injection device, but when it is inverted, it cannot be used as an injection device. Therefore, a bendable bellows tube was researched and developed so that it can be used not only in an upright state but also in an inverted state. However, although the bendable bellows tube is bendable, the fluid resistance such as fluid friction on the uneven portion of the inner surface of the bellows tube is relatively large, and the bellows tube absorbs liquid into the injection valve of the injector. It is extremely depressurized in the process of sucking up to the mouth, and the force of ejecting from the injection port of the injection device to the outside is, while the internal pressure in the injection container is high, if the internal pressure drops during the process of use, There was a drawback that the ejection force from the mouth was extremely weakened.

A second object is to position the liquid suction port of the flexible liquid suction tube together with the weight below the liquid surface so that liquid can be sucked, and thus to surely jet from the jet port of the jet device. To do. Further, according to the present invention, an opening portion at one end of the spiral flexible liquid suction tube is fixed to a suction port of a valve portion provided inside the injection head side, and a weight is attached to an opening portion at a free end thereof. A spiral flexible liquid absorption tube that is connected to the through hole provided in the weight and is fixed so that it can communicate with the through hole provided in the weight. By omitting the straight part from the spiral liquid absorption pipe structure part of the spiral flexible liquid absorption pipe between the connection parts of the connection part to the through hole provided in the weight, the weight is immediately weighted without passing through the straight part. It is connected to the through hole provided in the
The liquid weight of the spiral flexible liquid absorption tube is always positioned below the liquid surface by arranging the weight hanging from the opening of the free end of the spiral flexible liquid absorption tube so that A third object is to allow the liquid content in the injection container to be sucked up to the suction port of the valve portion so as to be ejected from the injection port by being positioned below.
