Embodiment Construction

[0022] The dispensing cap is a part integrally injection molded from a polymer material, such as polypropylene, and comprises a first annular section tubular part 2 of larger diameter, which is integrally connected at one end to the diameter by means of an elastically deformable web 4. One end of the smaller second tubular portion 6 of annular section. It is not necessary for the two tubular parts to have constant diameters or parallel sides, and it can be seen that the wall of the second tubular part flares downwards.

[0023] The larger tubular portion 2 is adapted to be connected to the neck of a bottle. For this reason, the diameter of this tubular portion 2 is substantially equal to the diameter of the neck of the bottle to be connected, or, like this embodiment, can also have a larger diameter annular cross-section connection portion 8, that is, its inner diameter is substantially equal to the outer diameter of the neck of the bottle. path. The connection part 8 may be...

Abstract

A dispensing cap for a beverage container constitutes a one-piece moulding of plastic material including a first circular section tubular portion for connection to the mouth of a liquid container and a second circular section tubular portion carrying a radially projecting circumferential flange, one end of the first tubular portion being connected to one end of the second tubular portion by a resilient, annular, integral web in which one or more flow openings are formed, the first and second tubular portions being coaxial and relatively movable in the axial direction between an open and closed position. The moulding further including two half shells of semi-cylindrical shape, the upper edge of each is integral with and sealed to the circumferential flange, the lower edge forms a sliding seal with the first tubular portion, whereby within the two half shells, there is a liquid flow space.

Description

technical field [0001] The present invention relates to dispensing caps for containers for storing beverages or other liquid or flowable substances, such as liquid cleansers, moisturizing creams or perfumes. More particularly, the present invention relates to a dispensing cap of the type constituting a one-piece molding of polymeric material comprising: a first tubular portion of circular cross-section having a first radius for connection to the mouth of a liquid container part, and a second circular cross-section tubular portion having a second radius, the second radius being smaller than the first radius, one end of the first tubular portion being connected to one end of the second tubular portion by an elastic annular integrated web, at the web One or more flow holes are formed in the plate, the width of the web is equal to or greater than the difference between the first radius and the second radius, the other end of the second tubular portion is closed, and the web and th...
