Problems solved by technology
The user cannot tell exactly when the product will be expelled from the spray tip after the container is inverted
For more viscous products, the user has to squeeze the container slightly to just fill the nozzle, and the user cannot be sure when the nozzle is filled and when the first drop of product will come out of the nozzle

Embodiment Construction
[0043] Although the present invention allows embodiments in many different forms, the description and drawings disclose only a few specific forms as examples of the present invention. Of course, the present invention is not limited to the described embodiments and its scope is determined by the following The appended claims point out.
[0044] For ease of illustration, most of the drawings illustrating the invention show the dispensing system in a typical orientation where the dispensing system would be at the top of the container when the container is stored upright with the bottom down, The words used, such as upper, lower, horizontal, etc., are generally based on the above positioning. It should be understood, however, that the dispensing system of the present invention may be manufactured, delivered, used and sold in orientations different from those described.
[0045] The dispensing system of the present invention is suitable for use with conventional or special contain...

A dispensing system (30) is provided for dispensing a product from a container having an opening. The dispensing system includes a spout (38) for communicating with the container opening. The spout (38) defines at least one discharge aperture (46), a distal seal surface (54) located distally of the discharge aperture, and a proximal seal surface (56) located on the exterior fo the spout (38) proximally of the discharge aperture (46). A nozzle assembly (60, 70, 80) is mounted on the spout (38) for movement between a retracted, closed position and an extended, open position. The nozzle assembly (60, 70, 80) includes a nozzle (60) having a dispensing passage (86) around at least a portion of the spout (38), a proximal seal surface (90) for sealingly engaging the spout proximal surface (56), and a distal seal surface (96) located outwardly of the nozzle proximal seal surface (90) for sealingly engaging the spout distal seal surface (54) when the nozzle assembly is in the retracted, closed position. The nozzle assembly also includes a resiliently flexible valve (70) that is sealingly disposed across the nozzle dispensing passage (86) at a location distally of the spout distal seal surface (54) and has an initially closed dispensing orifice (132) which opens in response to a pressure differential acting across the valve (70).
Description
technical field [0001] The present invention relates to a system for dispensing a product in a container. Such a system is particularly useful as part of a squeezable flexible container or its dispensing closure. Background technique [0002] There is a broad category of packaging that includes (1) squeezable containers, (2) dispensing systems that can be extended as unit parts of or attached to such containers, and (3) product. A type of container in which a single dispensing valve is used to discharge a single stream of product (the product may be liquid, paste or granular). See, eg, US Patent No. 5,839,614. Such containers include flexible, resilient slit-type valves. The valve is usually closed and can support the weight of the product when the container is fully inverted so that the product will not escape as long as the container is not squeezed. [0003] For certain types of products, such as gels, hair dyes, dressings, etc., it may be desirable to provide a disp...
