Description
Technical Field
The utility model relates to a liquid storage and output device and pen.
Background
Liquid storage and release devices are herein defined as devices that are capable of storing liquid at ordinary times and conveniently releasing liquid during use, and are generally defined herein as devices that store and release small amounts of liquid. Common ink pens, perfume devices, one-component glues or two-component glues, certain drug delivery devices are often typical items for their practical application. The most common liquid storage and release devices for single components are a large number of daily items, vials of quick-drying adhesives, eyedrops, and the like. There are also single-ended toothpaste tubes with one tube, multiple capsules and multiple mouths, as described in CN 03262723. They generally do not have the function of mixing multiple components. CN200880019646 or CN201310668512 are typical representatives of two common two-component storage output structures. The above conventional structure has a common problem that the liquid directly contacts the outlet position, and the component part may be volatilized and lost or contaminated by foreign substances, and the device structure is also unsuitable for complicated liquid mixing operation or slow-release storage because of the instant flow mixing at the outlet position. A chemiluminescent binary reaction type mixing output device is disclosed in the publication CN96219763.7, and a binary storage structure and a ball release mixing structure are assumed for its simple structure, but in practice, such a structure is too ideal to effectively protect the luminescent material before use and to effectively mix or release liquid during use. Patent CN200820109821.9 discloses a liquid output device, which provides various mixed output structures and pressure structures for pushing liquid to be output, and solves the above problems to a limited extent. In practice, the above-disclosed technology still has the disadvantages that the liquid can not be effectively output or the liquid can be pushed out uncontrollably by the pressure generated by the liquid when the reaction occurs, and in addition, the inconvenience of using a glass ampoule as a storage liquid and the safety hazard brought by the broken glass pieces need to be further improved and improved.

The buffer layer 5 arranged between the output port 1 and the film medicine capsule 4 can temporarily absorb the released liquid to avoid the liquid from rushing out of the output port, components with labyrinth passages except for liquid absorption materials such as fibers and the like can also be used as the selection of the buffer layer 5, and meanwhile, the buffer layer can also play a role in enhancing the uniform mixing. The buffer layer 5 formed by wrapping the adsorption material outside the film medicine capsule 4 can also play a role in adsorbing liquid medicine, and the adsorption material can be fluffy and can well discharge liquid during extrusion. It is of course also possible to have no buffer layer 5 if the space inside the soft-shell tubular chamber 2 is large. Then the soft shell of the soft shell tubular cavity 2 is kneaded to fully release and mix the liquid, and the liquid can be extruded out by turning the device upside down and downwards the output port 1.
The material of the film drug capsule can be Polyester (PET) with a thickness of 0.012mm compounded with cast polypropylene with a thickness of 0.025mm, polyethylene compounded with aluminum foil with a thickness of 0.006mm, and cast polypropylene with a thickness of 0.015mm compounded with aluminum foil with a thickness of 0.01 mm.
