Abstract: A bottle teat consisting of a soft elastic material for a drinking bottle, in particular for infants and small children, having: a teat flange, a hollow teat sleeve that projects upward from the teat flange and is connected at its bottom end to the teat flange, a hollow suction part that is connected at its bottom end to the top end of the hollow teat sleeve and projects upward therefrom, a dome-shaped palate-contacting region on a side of the mouthpiece facing the palate, at least one drinking hole in the palate-contacting region that extends from the outside to the inside of the mouthpiece, wherein: an elevated surface that bulges to the outside is on the outside of the palate-contacting region, and the at least one drinking hole is arranged in the elevated surface so that the suction part with the elevated surface can be pressed in a sealing manner against an inwardly bulging sealing surface on the inside of the cap bottom of a cap to cover the bottle teat.

Abstract: The invention relates to a feeding bottle comprising a color change indicator made of thermochromic pigments for temperature control, and the production and use thereof.

Abstract: An apparatus may include an insert configured to be positioned between a nipple and an opening of a bottle when the nipple is mounted to the bottle. The insert is configured to facilitate airflow out of the bottle and through an interface between the nipple and the bottle when the nipple is dispensing fluid from within the bottle. A system may include a nipple, the insert, and a bottle with an opening. A method may include providing the insert, and positioning the insert between a nipple and an opening of a bottle when the nipple is mounted to the bottle.

Abstract: A bottle teat consisting of a soft elastic material for a drinking bottle, in particular for infants and small children, having: a teat flange, a hollow teat sleeve that projects upward from the teat flange and is connected at its bottom end to the teat flange, a hollow suction part that is connected at its bottom end to the top end of the hollow teat sleeve and projects upward therefrom, a dome-shaped palate-contacting region on a side of the mouthpiece facing the palate, at least one drinking hole in the palate-contacting region that extends from the outside to the inside of the mouthpiece, wherein: an elevated surface that bulges to the outside is on the outside of the palate-contacting region, and the at least one drinking hole is arranged in the elevated surface so that the suction part with the elevated surface can be pressed in a sealing manner against an inwardly bulging sealing surface on the inside of the cap bottom of a cap to cover the bottle teat.

Abstract: The invention is directed to a push-pull closure for a drink container including a mouthpiece holder. The container includes a pin, which projects into the through-opening of the mouthpiece holder; several bars, parallel to the pin and arranged around the pin, which are connected to the mouthpiece holder and to the pin; a mouthpiece that is axially displaceable and sealing with respect to the mouthpiece on the outer circumference and accommodating the pin in the further through-opening; at least one circumferential seal element, which blocks and unblocks the passage of liquid through the further through-opening in an closing/opening position of the mouthpiece in the mouthpiece holder; and several ribs of a soft elastic material, axially extending on the circumference of the mouthpiece at the bottom, wherein the mouthpiece may be inserted into the mouthpiece holder, and the bars can engage free spaces and the ribs engage recesses between the bars.

Abstract: A process and an apparatus are described for the production of peroxyacids from concentrated solutions of hydrogen peroxide and an oxyacid. The total amount of concentrated hydrogen peroxide is divided into at least two portions which are added separately in series to the concentrated oxyacid.
