The present invention provides an ethyl-2-cyanoacrylate adhesive composition obtained as a result of significant improvement on conventional problems, that is, irritating odor and whitening of conventional ethyl-2-cyanoacrylate adhesive compositions. According to a method of the present invention for purifying an ethyl-2-cyanoacrylate adhesive composition, a sum total of an acrylonitrile content and an ethanol content is arranged to be in a range of 1 ppm to 150 ppm, by carrying out deaeration at the same time as injection of an inactive gas at a reduced pressure in a range of 100 Pa to 10000 Pa at a temperature in a range of 5&#xb0; C. to 50&#xb0; C. Thereby, the method of the present invention allows improving irritating odor and whitening.

Container for glue with stand

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

An .alpha.-cyanoacrylate adhesive composition having high thixotropy, excellent stability with age including difficulty of separation and excellent adhesiveness, for use of rubbers, plastics, metals or so, comprises (b) 10 through 20 parts by weight of polymers containing alkyl methacrylate having a weight average molecular weight of 100,000 through 300,000, (c) 2 through 20 parts by weight of ultrafine anhydrous silica, and (d) 0.001 through 20 parts by weight of quick curing additives represented by the formula (1), (b)-(d) being on the basis of (a) 100 parts by weight of .alpha.-cyanoacrylates: ##STR1## wherein X.sub.1 is a hydrogen atom or methyl group; X.sub.2 is a hydrogen atom, methyl group or cyano group; X.sub.3 is R.sub.2 or R.sub.2 CO in which R.sub.2 represents a hydrocarbon residue containing no anionically polymerizable group; and l, m and n are integers and (l+m).gtoreq.1 and n.gtoreq.1.

.alpha.-cyanoacrylate adhesive composition

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.

Discharge container with nozzle

A composite container for low viscosity liquids, capable of discharging the contents completely, without producing dripping of liquids after discharging adhesives, medicines, foods, ink and other low viscosity liquids. The container includes an inner container which contains the contents and includes an opening for discharging the contents, and an outer casing container covering the inner container body. A pressure medium is interposed between the inner container body and the outer casing container.

The present invention relates to an improvement of a nozzle cap for a composite container containing a low-viscosity liquid such as a humidity-curing type adhesive of .alpha.-cyanoacrylate-based adhesive, solvent-volatile type adhesive, various chemicals, food, and ink. A container is provided with a nozzle cap which includes a nozzle connected to a container body and a cap threadably mounted to the nozzle for closing a discharge port of the nozzle. A head of the cap is provided with a column element projecting inwardly for closing the nozzle and a head of the column element is provided with a concave hole into which the tip of the nozzle is removably inserted or fitted. A superior, unique effect is exhibited such that the closure of the nozzle is easily and completely performed, and adhesive or the like adhering to the tip of the nozzle does not spread around and cure, thereby preventing formation of an umbrella- or mushroom-shaped solid material.
