  • Patent number: 10532851
    Abstract: A container assembly includes a container body having a side wall encircling an axis, and a metal end for attachment to an upper edge of the side wall via heat-sealing. The outer peripheral region is shaped prior to application to the container body such that an annular channel is defined between an inner chuck wall and an outer chuck wall of the metal end. The metal end is pushed straight onto the side wall such that the upper edge of the side wall is received into the channel. The surfaces of the side wall and the opposing surfaces of the chuck walls have heat-sealable material thereon. The metal end is heated to melt and fuse the heat-sealable layers, thereby sealing the metal end onto the side wall. The metal end is shaped such that the free edge of the outer chuck wall is not exposed.

  • Patent number: 10099840
    Abstract: A cup made of a paper material having a fillable interior, which cup is formed by a conical sleeve and a bottom. The bottom is attached to the sleeve at the lower end of the interior with a bottom skirt in an essentially liquid-tight way. The sleeve and/or the bottom in the area of the bottom skirt and/or the bottom skirt itself comprises, at least in one area along the periphery, an outwardly projecting widening. A lower edge of the widening forms a standing surface for the cup. The widening can serve to hold another cup of the same type, and can act together with a similar cup during stacking. The cup can include a heat insulating outer sleeve.

  • Patent number: 9371149
    Abstract: An improved structure of paper cup, which comprising: a cup body and bottom; the cup body is designed with an annular side wall, and an outward folded arced cup edge is set on the ring edge at one end; the annular side wall is provided with an annular side wall mated with the annular side wall of the cup body far away from the cup edge to form holding space; the cup body and bottom form a holding space; particularly, an inflexed edge is formed at the annular side walls where the cup body is abutted with the cup bottom, thus reducing the height of the annular side wall for the mating of the cup body and bottom; when a large number of paper cups are stacked, the gap between cups could be reduced, thus increasing the storage amount and saving the storage and transportation cost.

  • Patent number: 9132947
    Abstract: A sealing disc (10) is used for closing orifices of containers (5). It has a film (20) for inductively coupling heat into the sealing disc (10). A sealing layer (25) is provided on that side of the film (20) which is intended to face the interior of the container (5) in order to seal, in sealtight fashion, the sealing disc (10) on the orifice of the container (5). Lines of weakness (26) are provided in the sealing layer (25) so as to form a removal opening (27) once the film (20) has been drawn off. One or more layers (40), which are connected detachably to the film (20), are provided on that side of the film (20) which is remote from the sealing layer (25). The layers (40) detach mare easily from the lam (20) than the sealing layer (25) and also detach more easily from the orifice of the container (5) than the sealing layer (25).

  • Publication number: 20020014520
    Abstract: The method for forming a container that comprises the following stages: the forming of the sidewall blank from a blank by wrapping it in a form that is closed in its horizontal section and by seaming its opposite edges together; the sealing of the sidewall blank at one end with a lid member, which is equipped with a discharge hole; the sealing of the sidewall blank at the other end with a bottom member; and the filling of the container. At first the lid member, the discharge hole of which is completely sealed with an openable closing member, is inserted into the end of the sidewall blank. Thereafter the container is filled through the end of the sidewall blank that was left open, and the container is sealed to form a tight container by sealing the end that was left open with the bottom member.
