The reclosable container (1), adapted to reduce the risk of contamination of the substance contained therein, comprises a hollow body (2) provided with a dispensing mouth (15) which can be plugged through respective detachable closure elements (4, 20, 23) which comprise plugs (6, 6b, 6c, 21, 21b, 25) which can be coupled to the mouth (15); the closure elements (4, 20, 23) are monolithic with the container (1); the plugs (6, 6b, 6c, 21, 21b, 25) are located on the closure elements (4, 20, 23) on the side thereof directed towards the mouth (15). The method comprises the formation of the closure elements (4, 20, 23) nonlithically with the container (1); during formation, the plugs (6, 6b, 6c, 21, 21b, 25) are formed on the closure elements (4, 20, 23) on the side of these elements which is directed towards the mouth (15); at the end of the formation, the plugs (6, 6b, 6c, 21, 21b, 25) are made to couple to the mouth (15). The container and method are used in the pharmaceutical, cosmetic, food industries, etcetera.

A strip like structure is formed in the shape of a succession of phials, of a heat-sealable plastic, with the phials molded with their respective bases open and their mouths each closed by a removable stopper element, each of the phials having a first set of webs disposed transversely about the middle of their respective longitudinal axis and a second set of webs formed at the mouth ends with narrow stiffening ribs on either side of an uppermost edge thereof, the first and second webs serving to interconnect the phials and the removable stopper elements closing the same, respectively. The interconnecting webs are provided with relative weakening creases located preferably midway between each two adjacent phials and disposed parallel to the phial longitudinal axis. Each terminal web of the second set has transverse butt portion disposed at right angles to the plane of the web, the butt having a width not greater than the width of the phial and a height equal to a depth of the second web.
摘要:
A process for printing and decorating an article by the use of sublimable inks, includes providing preformed images on a substrate, these preformed images are obtained using the sublimable inks; applying the substrate on surfaces of the article; applying a pressure to the preformed images for pressing the preformed images against the surfaces, providing a heat thermoretractable material and heating the heat thermoretractable material at a temperature suitable for causing a thermoretraction of the heat thermoretractable material for generating the pressure; heating the preformed images until the sublimable inks are transferred by sublimation onto the surfaces. The thermoretractable material can be polyethylene terephthalate (PET) or polyethylene naphthalate (PEN). An apparatus for printing and decorating an article by the use of sublimable inks has compression parts for applying a pressure to images provided on a substrate applied on surfaces of the articles. The images are obtained using the sublimable inks, a heater for heating the images at a temperature suitable for obtaining a transfer of these images on the surfaces by sublimation of the sublimable inks. The compression parts include a heat thermoretractable material, and the thermoretractable material which is PET or PEN.
摘要:
Process for recovering at least 70% of hollow glass microspheres having an average diameter, according to the ASTM D1214-1989, ranging from 5 to 200 μm contained in a mixture of drilling mud and cuttings which comprises: a) screening, if necessary, the mixture through one or more 5 to 20 mesh sieves; b) feeding the screened mixture to one or more cyclones and/or hydrocyclones arranged in series, each of which is fed with a volume flow-rate from 1.5 to 10 times higher than the maximum nominal operating value.
摘要:
An apparatus is disclosed for cleaning the bottom of mercury cathode electrolytic cells or the like, usable in closed cells which are cut off from the power supply and maintained under suction, characterized in that said apparatus consists essentially of a plate or strap that is displaceable along the bottom of the cell, and having an overall length substantially corresponding to the width of the cell-bottom to be cleaned, said strap normally resting on or near the bottom of the cell, and means for moving said strap along the bottom of the cell to scrape or dislodge mercury sludge and other residues that have accumulated during the operation of the cell. The means for moving the strap along the bottom of the cell may be manually actuated from outside the cell or they may be actuated by motor means situated outside the cell.
