  • Patent number: 11453531
    Abstract: The present disclosure is directed to a dosing cap (10). In an embodiment, the dosing cap (10) includes (A) a collar member (12). The collar member (12) has an annular skirt (18) depending from a base (16)(B). An inner surface of the skirt has a securing member for securing the collar member to a neck (21) of a container (20). The base (B) has (i) a top surface (30) and a bottom surface (32), (ii) a valve seat (34) is present on the top surface of the base. The valve seat has a center channel (36), and a radial channel (38), the channels extend through the base. The dosing cap includes (C) a plug member (40). The plug member is composed of a polymeric material. The plug member has the following components in inter-connected relationship: a head (42), a body (44), a leg (46), an ankle (48), and a flexible foot (50). The leg extends through the center channel, such that the head opposes the valve seat on the top surface of the base and the foot opposes the bottom surface of the base.

  • Publication number: 20190062022
    Abstract: The present disclosure provides a seal bar. In an embodiment, the seal bar comprises a base member having a flat front surface and a flat recessed surface a distance (d) behind the front surface. The front surface defines an x-axis, X. The flat recessed surface has a first endpoint (A1), wherein an axis that is perpendicular to the flat recessed surface at the first endpoint (A1) defines a first y-axis (Y1). The seal bar has a concave surface extending the distance (d) between the first endpoint (A1) and a point (B1) on the flat front surface. The concave surface defines a quadrant arc segment of an ellipse between the first endpoint (A1) and the point (B1).

  • Patent number: 9481143
    Abstract: Disclosed are multilayer film structures having annular profiles, and methods and apparatus of making the structures disclosed. The annular multilayer articles have a uniform thickness, at least four layers and comprise overlapped and non-overlapped circumferential areas; wherein the layer structure of the non-overlapped area is doubled in the overlapped layer. A method of making the structure includes providing a multilayer flow stream with at least four layers of thermoplastic resinous materials; feeding the multilayer flow stream to a distribution manifold of an annular die to form an annular multilayer flow stream; and removing the annular multilayer flow stream from the annular die to form the annular multilayer structure.
