The present invention relates to a base composition for a microneedle patch and a microneedle patch comprising the same. The base composition comprises a first HPMC, a second HPMC and PVP/VA, wherein the viscosity of the first HPMC is greater than that of the second HPMC, the weight ratio of the first HPMC relative to the second HPMC is 1:0.1 to 1:1.2, and the amount of the PVP/VA is 0.25 wt % to 2 wt %. By controlling the constitution of the base composition, the microneedle patch can not only be demolded smoothly during the stage of the production, but also obtain the desired softness, flatness, flexibility, skin adhesion during the stage of use and humidity resistance during the stage of storage.

An opening and closing structure for ink cartridge, the ink cartridge includes a cartridge body and a lid, engaged to form a container to house a replaceable ink bag. Each of the two corresponding sides of the lid where the lid and cartridge body engage is disposed with at least a protruding hook element. Each of the two corresponding long side walls of the cartridge body is disposed with at least a latch unit. The latch unit includes a trench and a resilient latch element. As such, the lid can be easily engaged to and disengaged from the cartridge body for replacing the ink bag.

Opening and closing structure of ink cartridge

An ink cartridge with replaceable ink bag is provided, including a cartridge body, an ink bag and a lid body. The lid body is removably engaged to the cartridge body to house the ink bag. The wall on long side of the cartridge includes at least a retention block. The ink bag includes a trigger based on amount of remaining ink, a bag body and a positioning element. The bag body is partially glued to the positioning element. The surroundings of the positioning element are disposed with at least a retention element. The retention element can be inserted between the retention block and the bottom of the cartridge body for fixing the ink bag inside the cartridge. As such, the cartridge body and the lid body of the present invention can be reused to save the cost as well as resources to reduce the environmental waste.

Ink cartridge with replaceable ink bag

An ink cartridge apparatus for continuously supplying ink is provided, including a connection device, an exposed chip socket and a filtering device on an ink cartridge main body. The connection device is for connecting to an ink bottle and the filtering device is for filtering the impurity from the ink flowing from the ink bottle into ink cartridge main body. The exposed chip socket is for the user to replace the chip more conveniently. With the ink supply mechanism of ink bottle into ink cartridge main body, the ink cartridge main body can maintain good ink quality and when the threshold set by the chip is exceeded, the replacement of the chip can be done without removing the entire ink cartridge from the printer so as to achieve the object of continuously supplying ink.
