Abstract: The purpose of this invention is to prevent outside air from entering the bypass pipe portion when air is taken in the vessel for the prevention of a negative pressure, and thereby to secure normal, smooth liquid-discharging operation in the upside-down position of the vessel. For this purpose, the vessel equipped with a manual pump is also provided with a change-over valve unit 20 to switch the liquid supply to the manual pump 1 in response to the change in the posture of the vessel from the upright position to the upside-down position, and vice versa, so that the vessel can be used to discharge forcibly the liquid even in its upside-down position. In such a vessel, the channel taking outside air into the vessel 50 for preventing a negative pressure has an opening to the vessel 50 at the rear of the cap unit 40.

Abstract: A thin-walled metal tube includes a tubular nipple section, a shoulder section joined to the nipple section, a tubular barrel section and a border section connecting the shoulder and barrel sections, the barrel section being defined by a wall having a thickness in the range of between about 20 microns and about 70 microns. The border section includes a region which changes in thickness, the wall thickness of the border section being greater than the thickness of the wall defining the barrel section and the thickness changing region having a cross-section having either an arcuate or a tapered region.

Abstract: A side seamless composite type collapsible tube having a tubular nipple section, a shoulder section and a tubular barrel section for receiving an extractable content is provided. The tube sections are formed of a continuous wall of metallic material having a wall thickness from about 20 to 70.mu. with at least a portion of the tubular barrel section coated with a synthetic resinous layer of from about 50 to 500.mu. thick. A method of forming the tube from a metallic blank material is also provided.
