摘要： The invention concerns a novel chain-terminated polymeric composition, comprising hydroxyl-terminated polyesters and a method for preparing the composition and the use of the chain-terminated polymeric composition as a plasticizer. They play a predominant role in the field of metal vacuum closures (Twist-Off and Press-On-Twist-Off closures). Selection criteria regarding the suitability of plasticizers in food contact applications are properties such as low plasticizer volatility, low plastisol viscosity, PVC compatibility, softness and resilience of the gasket as well as non-toxicity and high plasticizer migration resistance. The invention concerns the chemical equation of FIG. 1 for obtaining the suggested chain-terminated polymeric composition, wherein x, y, and z are the stoichiometric ratios of dibasic carboxylic acid (DCA), glycerol or polyglycerol (GPO), and monobasic carboxylic acid (MCA), k is the number of methylene groups in the dibasic carboxylic acid, (k+2) is the number of carbon atoms therein, m is the degree of polymerization of polyglycerol used, (m+2) describes the hydroxyl functionality thereof, l is the number of methylene groups in the monobasic carboxylic acid, (l+2) is the number of carbon atoms in the monobasic carboxylic acid, and n is the degree of polymerization of the polyester formed by glycerol or polyglycerol and the dibasic carboxylic acid.

摘要： What is proposed is a closure unit consisting of a glass container (50) with external, circumferentially offset threaded elements (54, 55) on a container neck (52) of the glass container, and a closure cover made of sheet metal, wherein the closure cover (1, 2) has an encircling plastics layer (30; 30h, 30v) on the inside of the cover. The closure cover is pressed onto the container neck (52) and can be opened with a rotational movement via the threaded elements (54, 55) and a vertical section (30v) of the plastics layer. The container neck (52) has a horizontal end surface (52a) on which a horizontal section (30h) of the plastics layer rests under pressure in a sealing manner. A central region (11) of the closure cover passes with an adjoining, circumferentially oriented transition zone (11a, 11b, 11c) into an axially downwardly projecting skirt section (12) which ends in a roll-up region (21a, 21; 22). The plastics layer (30; 30h, 30v) is arranged on the inside of the cover in a manner adhering to the transition zone (11a, 11b, 11c) and the skirt section (12). An axial extent (h0) of the skirt section (12) and a radial dimension (b52) of the horizontally oriented end surface (52a) of the container neck (52) form a first ratio (v1) which is smaller than three.

摘要： The invention relates to a container made of glass or hard plastic having a container neck (52) with a plurality of external thread elements (53, 54, 55, 56, 57, 58), which are offset circumferentially relative to one another, as thread segments. The container can be closed by means of the thread segments by a closure cap made of metal sheet, wherein the closure cap (1, 2) has a circumferential plastic layer (30;30h,30v) on the inside of the cap and on the rim of the cap which has a sealing and retaining action. The closure cap can be pressed onto the container neck (52) and over the thread elements (53, 54, 55, . . . ) during closure and a vertical portion (30v) of the plastic layer can be opened with a rotary movement relative to the thread segments (53, 54, 55, . . . ). The container neck (52) has an upper horizontal end face (52a) as an annular surface which is adapted and suitable to be pressed into a horizontal portion (30 h) of the plastic layer (30;30h,30v) of the closure cap (1.2) under pressure and to produce a seal under pressure. An axial spacing (h54) is defined which extends between axially upper ends (53a, 54a, 55a, 56a, 57a) of the thread segments (53, 54, 55, 56, 57, 58) and a horizontal plane (E52a) through the horizontally oriented end face (52a) of the container neck (52) of the glass container (50). An annular width (b52) of the upper horizontal end face (52a) is defined as an annular surface. A ratio of the axial spacing (h54) to the annular width (b52) is less than 1.35.
