Embodiment Construction

[0045] see now figure 1 with Figure 1a , which show the components of the container, comprising a body part or reservoir 2 of flexible plastic comprising a neck 4 with an external thread.

[0046] The switch seat of high density polyethylene is usually indicated by 6, which includes an outer ring 8, forming an inner cavity suitable for seating and screwing on the neck 4 of the container at its lower part, thereby fixing the seat 6 to the body part 2 Above, the inner wall of the sleeve 8 is located in the neck 4 and defines an outlet of the body part 2 .

[0047] Molded integrally with the sleeve 8 is a cylindrical switch support cavity 12 connected thereto by a plurality of thin, circumferentially spaced ribs 10, initially open at its upper and lower ends. The upper part of the chamber 12 has formed therein an annular inlet 14, the purpose of which will become clear below.

[0048] An elastomeric or silicone rubber control switch of soft thermoplastic material is generally...

Abstract

A container includes a flexible body member (2) closed by a lid portion (26) having an outlet (28), a control assembly within the lid portion for controlling flow from the body member (2) to the outlet (28) The liquid flow control assembly includes an integrally molded seat (6) located on the body member (2). The seat (6) includes an outer ring sleeve (8) and an inner switch support cavity (12), a single piece of plastic. A molded control switch (16) is located on the seat (6) to define a closed space below it, which space is connected to the atmosphere, and is designed so that when pressurized inside the body member (2), the pressurized The liquid flows between the sleeve (8) and the cavity (12), deforming the control switch (16) and flowing out of the outlet (28). After the above pressure is released, the control switch (16) returns to the outlet (28). position on.

Description

technical field [0001] The present invention relates to a container, in particular to a container for discharging pastes, fats, milks and other similar products, hereinafter referred to as liquids. Background technique [0002] There are a wide variety of containers available for the controlled discharge of a liquid product through an outlet having a control switch in the form of a flexible membrane with a nose or stud which, due to deformation of the membrane, acts to close the outlet Moves between a position that prevents liquid from draining and an open position that allows liquid to drain through the outlet. [0003] One such device is disclosed in U.S. Patent No. 5,454,494, wherein the membrane is mounted on a hollow cylindrical support and then placed in a rigid insert in the container, and the liquid flows from the container through a cylindrical channel. To the discharge chamber, when the liquid in the container is pressurized, it is discharged from the chamber with...
