(57) Abstract: A plastic container is coated with DLC film as a desirable oxygen barrier so that it is suitable for containing oxygen-sensitive or carbonated beverage. A coating device comprises an outer electrode arranged outside a plastic container (5), an inner electrode (11) arranged inside the plastic container (5), a pipe (12) through which carbon source gas is supplied to the plastic container (5) pumped to a low pressure, and a high-frequency oscillator (9) for applying voltage between the outer electrode and the inner electrode (11) after supplying the source gas to generate a plasma for depositing DLC film on the inner wall of the plastic container (5). The outer electrode includes a bottom electrode (4) arranged along the bottom of the plastic container (5) and a wall electrode (3) arranged along the inner wall of the plastic container. The bottom electrode (4) is located below half the complete height of the plastic container (5).

An can end tray (1) for storing a plurality of arrays of can ends (w) while the can ends are being conveyed has a substantially rectangular upstanding side wall (2) having a height at least equal to the diameter of the can ends, and a plurality of can end supports (3) on a bottom of said tray for supporting arrays of can ends thereon, said can end supports having a plurality of partitions (8) for holding the arrays of can ends spaced from each other when the arrays of can ends are placed on said can end supports. A plurality of spacers(9) are disposed on said side wall in longitudinal alignment with said can end supports for spacing said side wall and ends of the arrays of can ends from each other when the arrays of can ends are placed on said can end supports. When the arrays of can ends are placed on said can end supports, the spacers extend across the can ends at the ends of the arrays of can ends, defining gaps (x) between said side wall and the can ends at the ends of the arrays of can ends.

A surface-treating apparatus for can body blanks includes a means for cutting (10) an original sheet into can body blank materials having a predetermined width and capable of dividing into plural can body blanks, a conveying path (12) for conveying the can body blank materials, a material-feeding means for intermittently feeding the blank material to the conveying path, a means for heating the blank material first and second film-feeding means for respectively feeding a printed biaxially-stretched polyester film and a plain polyester film to both sides of the blank material along its conveying direction, first and second press-bonding means for respectively successively press-bonding under heat said both films to both sides of the blank material and coupling the blank materials into a continuous form while defining metal-exposed areas for welding parts at both side edges of both surfaces of the blank materials, a means for cooling the continuous sheet of the blank materials, a blank material-cutting means for cutting the continuous sheet in its width direction at the space area between adjacent print pattern on the biaxially-stretched polyester film into surface-treated blank materials, a means (7) for driving the surface-treated blank material out of the conveying path, and a means (9) for dividing the surface-treated blank material into individual can body blanks according to the print patterns.
摘要:
A can end is seamed to a cylindrical can filled with contents. The can is fed along a substantially elliptical path including straight and arcuate paths. While the can is being fed along the straight path, the can end is seamed to the can by a linear seaming device. At the same time, the can end is rotated by a can end holder which has a pinion gear held in mesh with a rack which extends fully along the elliptical path. The rack is composed of separate rack members which are relatively movable to adjust the tension of an endless chain that moves can ends and cans along the elliptical path.

There is disclosed a sealed container of the disposable type and having a container body (1) made of cardboard, paper or the like and internally lined with waterproof material, and a closure member (4) which hermetically seals one end of the container body, in which:
the closure member (4) includes a panel (7) which closes the open end (5) of the body (1), and a peripheral flange (6) which overlies and which is secured to the open end region (1a) of the body; a covering (8,12) is provided on an exposed end face (1 b) of the body; a reinforcing member (9) is secured to a peripheral area of the end region (1a) of the body; and the peripheral flange (6) is secured to the end region (1a) of the body at a position corresponding to the position of securement of the reinforcing member (9).
摘要:
A method of forming the outline of a can shell, comprising the step of pressing, from the outside, a pressing member (44), against the peripheral wall of the can shell (4) having an inside maintained at a specified pressure with gas to form recess-deformed parts (56) of a specified shape in the peripheral wall of the can shell (4), whereby the strength of the can shell (4) can be prevented from lowering and the inner surface of the can shell (4) can be prevented from being scratched, and film on the inner surface of the can shell can be surely prevented from being damaged, three-dimensional patterns can be formed by recess-deforming the can shell (4) at specified positions, and an outline formation with a high designability can be easily applied to the can shell (4) at a low cost.
