Provided is a 2-cyanoacrylate-purifying method for decoloring a 2-cyanoacrylate which has been colored, and preventing further coloring of the 2-cyanoacrylate thus decolored. The 2-cyanoacrylate-purifying method includes the steps of: (a) adding a specific polyhydric aromatic compound to the 2-cyanoacrylate which has been colored; and (b) storing, at a temperature in a range of 0&#xb0; C. to 40&#xb0; C. for 0.5 day or more, the resulting mixture obtained in the step (a), and then subjecting the mixture to reduced pressure distillation.

Container for glue

There is provided a container for display and storage comprising a body rectangular base sheet and a lid rectangular base sheet connected in a double spread sheet (or folded) condition by a folding line along the longitudinal direction. The rectangular base sheet on the body side is provided with a transparent cover in which an article can be contained and an opening is provided in the reverse face through which the article can be freely taken out and put in.

Container for display and storage

The present invention relates to an improvement of a discharge container with a nozzle for housing a liquid, for example, an instantaneous adhesive or another moisture curing type adhesive, various adhesives such as solvent volatilizing type adhesive, various chemicals, foods, inks and medical supplies. The present invention is a discharge container with a nozzle which includes a container body for housing contents, a nozzle threadly attached to the container body, and a dual-shoulder type protective frame having a neck hole, wherein the base end of the mouth of the container body is inserted through the neck hole of the dual-shoulder type protective frame, and the container body is threadly attached to the nozzle, thereby allowing them to be made a one-piece structure. The present invention is a highly safe and easy-to-use container which can house a relatively high viscosity liquid such as jelly-like and grease-like ones, be stood up, discharge the contents smoothly until before the last service, provide no liquid run and leakage, and discharge the contents completely until before the last service. Particularly, the container of the present invention is excellent in safety and operability such that the container is opened or closed through the protective frame without directly touching the container body, so that the tube when used is not deformed or broken until before the last service.
