The annular seal piece is of such a shape as to be deflected radially outwardly upon contact with the cylindrical outer peripheral surface of the mouth-and-neck portion of a container. The annular contact piece is brought into contact with an annular boundary surface extending from an annular top surface to an annular outer peripheral surface of the mouth-and-neck portion of the container when viewed arcuately in a sectional view. An annular thin-walled region positioned radially inwardly of the annular seal piece and the annular contact piece are further formed in the outer peripheral edge portion of the inner surface of the top panel wall.

Abstract: A method of inspecting a wrap-fitted state of a cap that is wrap-fitted to the neck of a bottle by detecting a positional relationship between a bottle mark and a cap mark, wherein an optical lens is arranged at a higher position on the vertical center axis of the bottle to which the cap is wrap-fitted, a single camera is arranged at a higher position on the optical axis of the optical lens to image the bottle mark and the cap mark through the optical lens, an illumination device is arranged for illuminating the bottle mark and the cap mark, the bottle mark and the cap mark are simultaneously shot by the camera, and the obtained image is sent to an image processor to detect a positional relationship between the bottle mark and the cap mark.

Abstract: A method of washing a container,including charging a material to be contained into a container body having a mouth-and-neck portion; mounting a container closure on the mouth-and-neck portion of the container body, the container closure having a top panel wall, a cylindrical skirt wall extending downwardly from a peripheral edge of the top panel wall, and a washing liquid passage formed in at least one of an upper portion of the skirt wall and a peripheral edge portion of the top panel wall; and jetting a washing liquid at the container closure so that the washing liquid passes through the washing liquid passage and enters a space between the mouth-and-neck portion of the container body and the skirt wall of the container closure, thereby washing an outer peripheral surface of the mouth-and-neck portion of the container body and an inner peripheral surface of the skirt wall of the container closure. The washing liquid is at a temperature of 65° C. to 70° C.

Abstract: A container closure is composed of a closure body, an outflow tube, and an outer cap. The outflow tube is pivotably mounted on the closure body. The outer cap is mounted on the closure body pivotably between a closed position and an open position. When the outer cap is pivoted from the closed position toward the open position, the outer cap contacts the outflow tube located at the closed position to erect the outflow tube from the closed position to the outflow position. The outer cap is then separated from the outflow tube and brought to the open position. When the outer cap is pivoted from the open position toward the closed position, the outer cap contacts the outflow tube located at the outflow position to tilt the outflow tube from the outflow position to the closed position, and the outer cap is also brought to the closed position.

Abstract: A cap comprises a cap body fitted and secured to the mouth of a container, an upper closure provided in the cap body, and a ring-like member which covers the outer surface of a skirt portion of the cap body. The ring-like member and the skirt portion are coupled together through breakable bridge portions. These two members are separated away from each other via cut surfaces but are intimately contacted to each other at the cut surfaces. The cap can be easily removed by hand from the mouth of the container, and can be separated from the container at the time of disposal.

Abstract: A plastic container closure comprising a top panel, a skirt portion, an annular protruded portion that is formed inwardly from the inner surface of the top panel and on the inside of a portion near the root of the skirt maintaining a small gap therebetween, and a sealing liner that is fitted by press-molding on the inside of the top panel, wherein a substantially vertical portion is formed on said liner along the inner surface of the annular protruded portion, and sealing performance is maintained by the engagement between the outer edge of the mouth of the container and the substantially vertical portion. Since the sealing is accomplished over a surface having a predetermined width in the up-and-down direction, the sealing performance is not impaired even when the top panel is deformed by the pressure. Moreover, favorable sealing performance is maintained even against shock that is given to the container at the time of fitting the closure.
