  • Patent number: 11643254
    Abstract: 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).

  • Patent number: 10633149
    Abstract: 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.

  • Patent number: 5726394
    Abstract: The invention relates to an apparatus for charging a weighing device arranged upstream of a packaging device with fragile foodstuffs of irregular size, in particular potato chips (4), comprising a dosing trough (1) with a free discharge side (8), a weighing container (3) and/or a storage container (2) arranged upstream of the weighing container (3). The dosing trough (1) is closed off at its free discharge side (8) by an end wall (9) and a discharge opening (10) is provided in the base (5) of the dosing trough (1) at the discharge side (8). The size of the discharge opening (10) defines a maximum target size relative to the size of the respective foodstuff (4) to be weighed and packaged. The base (5) of the dosing trough (1) forms an edge region (11) about the discharge opening (10) and a support for the foodstuff (4) exceeding the target size.

  • Patent number: 4357710
    Abstract: Radio apparatus and in particular VHF transmitter and receiver apparatus for aeronautical use comprises a frequency synthesizer 17 which is able to generate any desired frequency within the range of the radio and a number of frequency channel selection devices. These selection devices include a channel tuning switch 11, 11' which is arranged on the front panel of the apparatus and which can be adjusted to select any desired channel within the frequency range of the radio and a number of channel selectors 12, 12'; 13, 13'; 14, 14' which can be preset to call up certain fixed channels as desired. A changeover switch 16a at the front panel of the apparatus makes it possible to select any one of the channel selectors 12, 12'; 13, 13'; 14, 14' or the channel tuning switch 11, 11'. All the channel tuning devices are of similar construction and are mechanical stepping switches but the adjustment devices for the fixed channel selectors can only be actuated by means of tools.
