Abstract
A plastic cap for dispensing liquids to be connected to the neck of a deformable container, includes a main body having a first outer wall that can be assembled to the neck of the container and an inner coaxial wall that can be introduced inside the container to seal the neck. The main body has a generally cylindrical central part with a non-axial outlet for the liquid, and with fins for fastening a liquid suction pipe. The body has a hook near the outer edge for cooperating with a corresponding hook on the cover connected with the main body by means of a hinge. The cover has a central hollow cylindrical element for engaging and sealing the central part. The main body is formed with an opening under the hook to facilitate molding.
Claims7
A plastic cap for dispensing liquids adapted to be connected to the open neck of a deformable container having inner and outer wall portions and an upper edge for the passage of liquids through a suction pipe, comprising:
- a main body;
- a cover, and a hinge connecting the main body to the cover formed as a single molded piece;
- the main body being formed with a base surface and a peripherally located, depending cylindrical outer wall and a depending cylindrical inner wall for sealingly engaging the inner and outer wall portions of the open neck of the container respectively;
- the base surface including a generally centrally located, hollow cylindrical part projecting from the base surface, a distal end of said cylindrical part having an outlet opening for liquids and a first hook located near an outer edge of the base surface and projecting upwardly therefrom, said central part formed with inwardly projecting fins for engaging and securing the suction pipe therein for drawing liquid out of the container;
- the cover formed with a depending hollow cylindrical element sealingly engaging the cylindrical part of the main body when the cover is closed for sealing the outlet opening and a second hook formed in an outer edge of the cover for cooperating with the first hook;
- and
- the main body being formed with a hole formed through the base between the inner and outer cylindrical parts under the first hook said hole located opposite the upper edge of the open neck and being sealed against liquid flow when the base is connected to the open neck of the container.

- a depending ring projection formed between the outer wall and the inner wall, said projection sized for matching the upper edge of the container opening;
- and
- the main body being formed with a hole formed through the base between the inner and outer cylindrical parts under the first hook and outboard of the ring projection, said hole located opposite the upper edge of the open neck and being sealed against liquid flow when the base is connected to the open neck of the container and the ring projector engages the upper edge thereof.
