Description

BACKGROUND OF THE INVENTION

Field of the Invention

This invention relates to a container insert for chemical containers and more particularly relates to a single draw container insert having two metered flow outlets.

Description of the Related Art

Applicant has received many patents relating to container inserts, one of which is U.S. Pat. No. 10,618,705 B1. In many of those patents, the chemical is drawn upwardly from the liquid container by two draw tubes so that two chemicals may be dispersed with the tubes. Although Applicant's earlier patents have experienced commercial success, the two different draw tubes and related materials are somewhat expensive to manufacture.

SUMMARY OF THE INVENTION

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key aspects or essential aspects of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter.

The single draw container insert of this invention provides two metered flow outlets. The container insert of this invention is designed to be used with a liquid container and includes a lower ring-shaped member having a horizontally disposed ring-shaped and disc-shaped bottom wall having an upper side and a lower side. The bottom wall has a central opening formed therein which has a hollow tube extending downwardly therefrom. The lower end of the hollow tube has oppositely disposed and radially spaced-apart openings formed therein.

A ring-shaped valve member is rotatably mounted in the lower member. The valve member has a central opening formed therein and an opening formed therein inwardly of the wall member. The sizes of the openings in the valve member control the volume flow rate. The outer opening may be controlled by the apparatus with which the insert is utilized.

It is therefore a principal object of the invention to provide an improved single draw container insert having two metered flow outlets.

A further object of the invention is to provide a device of the type described which enables different metered flows to be discharged from the apparatus.

These and other objects will be apparent to those skilled in the art.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Embodiments are described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the invention. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense in that the scope of the present invention is defined only by the appended claims.

The single draw container insert having two metered flow outlets of this invention is referred to by the reference numeral 10. The container insert is designed to be used with a liquid container having an outlet opening. Insert 10 includes a lower ring-shaped member 16 having a horizontally disposed ring-shaped and disc-shaped bottom wall 18 having an upper side 20 and a lower side 21. Bottom wall 18 has a central opening 22 formed therein. A hollow tube 24 extends downwardly from opening 22 and has a barbed lower end 26. The lower end of tube 24 has oppositely disposed and radially spaced-apart openings 28 and 30 formed therein. A ring-shaped wall 32 extends upwardly from the outer end of wall 18 to form a cavity 70. The ring-shaped wall 32 has an upper end 34 and a cylindrical recessed lower end 36.

The numeral 38 refers to a ring-shaped valve member having a vertically disposed wall member 40 having a lower end 42 and an upper end 44. A horizontally disposed wall 46 extends between wall 40 above the lower end thereof. Valve member 38 has a central opening 48 formed therein and an opening 50 formed therein inwardly of wall member 40. Valve member 38 includes a centrally positioned tube 52 which extends upwardly from wall 46 and has an upper end 54. As seen, central opening 48 is positioned within tube 52.

It should be noted that valve member 38 is selectively rotatably mounted in member 16. FIGS. 1-6 illustrate a single draw container insert having two metered flow outputs which is dependent on the diameters of openings 48 and 50 in valve member 38. When the insert is assembled, as in FIG. 6, liquid may flow from the container by way of cut-outs 28 and 30, up through hollow tube 24 into receptacle 47, and further through openings 48 and 50 in a dual metered manner. The liquid flowing upwardly through opening 50 passes into the area between elements 44 and 54. The liquid flowing upwardly through opening 48 passes into the centrally positioned tube 52. Thus, two independent and metered flow rates are provided. The metering may be changed by changing the element 38 having different opening diameters.

There may be situations wherein openings 48 and 50 are controlled by the apparatus which is in communication with openings 48 and 50.

FIG. 7 illustrates a single draw container insert 10 of this invention. In FIG. 7, the numeral 60 designates an insert having a single draw 62 extending therefrom which will be inserted into a container having liquid therein.

Thus it can be seen that the invention accomplishes at least all of its stated objectives.

Although the invention has been described in language that is specific to certain structures and methodological steps, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures and/or steps described. Rather, the specific aspects and steps are described as forms of implementing the claimed invention. Since many embodiments of the invention can be practiced without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
