Ink bottle

Abstract

The invention discloses an ink bottle which comprises a bottle body, an inner bottle body arranged in the bottle body and a cap connected to a bottle opening in the upper portion of the bottle body in a threaded manner. A conical surface is formed in the middle of the inner bottom of the bottle body. The portion, located on the periphery of the conical surface, of the inner bottom of the bottle body is a slope face. The inner bottle body comprises a circular temporary storage groove, a soft connecting pipe integrally connected to the lower portion of the temporary storage groove and a liquid inflow cover connected to the lower end of the connecting pipe. An outer turned edge abutting against the upper end of the bottle opening is formed at the upper end of the temporary storage groove. The whole connecting pipe is in an arc shape. A flow stop wall extending in the direction of the sphere center of a semi-spherical surface is formed at the lower end of the liquid inflow cover. A supporting head is formed on the periphery of the lower end portion of the flow inflow cover. The inner top of the cap is integrally provided with a piston body matched with the inner wall of the temporary storage groove. According to the ink bottle, little ink can be sucked into the temporary storage groove through the piston body while the cap is unscrewed, the ink can be sucked conveniently, contamination to the upper portion of a pen is avoided, meanwhile the whole bottle of ink can be used completely, and resources are saved.

Description

technical field [0001] The invention belongs to the field of office supplies, and in particular relates to an ink bottle structure. Background technique [0002] The Chinese patent with the application number CN00264490.8 discloses a pneumatic ink bottle, which adds a self-closable inner plug of rubber material in the mouth of the bottle, and connects a suction pipe under the inner plug. When the pen absorbs ink, insert the pen into the rubber stopper, squeeze the bottle body with your hands to increase the air pressure in the bottle, and the ink will flow into the pen along the closed door. Although this kind of ink bottle is convenient to absorb ink to a certain extent, it has the following defects: 1. The strength of pressing the ink bottle is not easy to control. If the pressure is too small, the ink is difficult to enter the pen tube, and if the pressure is too large, it may cause the pen to break away from the rubber stopper. 2. The air in the empty pen tube is diffic...

Problems solved by technology

Although this kind of ink bottle is convenient to absorb ink to a certain extent, it has the following defects: 1. The strength of pressing the ink bottle is not easy to control. If the pressure is too small, the ink is difficult to enter the pen tube. If the pressure is too large, the pen may break away from the rubber stopper, causing 2. The air in the empty pen tube is difficult to discharge, and it is difficult to fill the pen tube with ink, that is, the air squeezed out from the pen tube stays in the rubber stopper and the funnel-shaped straw, and part of the ink enters the pen tube. After that, when the ink bottle is pressed again, it is difficult for the ink to enter the pen barrel again
