Abstract
A grasping auxiliary for carrying an article or articles includes a tubular body 2. Each of opposite side ends 6a and 6b of the tubular body 2 with notches 3 provided therebetween is formed into a curved-face shape having no corner to facilitate the fitting of a grip portion 5 of an article receptacle such as a film bag into the tubular body 2 and to moderate the pressure contact of the opposite side ends 6a and 6b with a hand. A plurality of wrinkles are formed on an inner peripheral surface of the tubular body 2 for preventing the sliding movement of the grip portion 5 within the tubular body 2.
Claims8
A grasping auxiliary for carrying an article or articles, comprising a long tubular body formed from a polymer material into a substantially circular shape or a polygonal shape in section perpendicular to a lengthwise direction with notches provided in part, so that a grip portion of an article receptacle can be fitted into said tubular body through said notches, whereby the article receptacle can be carried in a state in which an outer peripheral surface of said tubular body has been grasped, wherein
- each of opposite side ends of said tubular body with notches provided therebetween is formed into a curved-face shape having no corner in order to facilitate the fitting of the grip portion into said tubular body and to moderate the pressure contact of said opposite side ends with a hand, and a plurality of wrinkles are formed on an inner peripheral surface of said tubular body in order to prevent the sliding movement of the grip portion within said tubular body.
A process for producing a grasping auxiliary for carrying an article or articles, comprising a long tubular body formed from a polymer material into a substantially circular shape or a polygonal shape in a section perpendicular to a lengthwise direction with notches formed in part, so that a grip portion of an article receptacle can be fitted into said tubular body through said notches, whereby the article receptacle can be carried in a state in which an outer peripheral surface of said tubular body has been grasped,
- said process comprising the steps of folding a long cylindrical base material made of a polymer flatly with halves integrally superposed on each other, and curving or bending said base material to form a tubular body having a double structure, so that each of opposite side ends of the tubular with the notches provided therebetween is formed into a curved-face shape having no corner to facilitate the fitting of the grip portion into said tubular body and to moderate the pressure contact of said opposite side ends with a hand, and so that a plurality of wrinkles are formed on an inner peripheral surface of said tubular body for preventing the sliding movement of the grip portion within said tubular body.
