4 Claims, 3 Drawing Figures IIIIIIIIIIIIII CONTAINER CONSTRUCTION BACKGROUND OF THE INVENTION The present invention relates as indicated to a new container construction, and relates more particularly to a container for dispensing granular materials or the like.
A multitude of containers have been designed and are currently being marketed for dispensing solid, granular material such as soaps, detergent, and the like. Such containers have in the past been commonly made of cellulosic material, such as cardboard, with dispensing containers made entirely of plastic material being more recently in use. Although both cardboard and plastic dispensing containers have been generally satisfactory for the purpose intended, certain drawbacks are characteristically encountered, either in the manufacture, or use, or both, of presently available containers of this type. For example, cardboard dispensing containers are typically rectangular in shape, thereby making difficult the total dispensing of the granular material from the container. In addition, cardboard containers are susceptible to the absorption of moisture, which is objectionable due both to the loss of strength and integrity of the cardboard material and the possible caking of the granular material in the presence of such moisture, with such caking impeding the dispensing of the material from the container.
The use of plastics has essentially eliminated the problem of moisture, but not without the attendant disadvantage of being relatively expensive to manufacture.
SUMMARY or THE INVENTION With the above in mind, the primary object of the present invention is to provide a dispensing container comprised both of cardboard and plastic construction. In accordance with the invention, the body of the container is of cardboard, with the bottom and top thereof being of molded plastic material, suitably configured to tightly fit over the opposed ends of the body of the con tainer to complete the container assembly.
A more specific object of the present invention is to provide such a container wherein the cardboard body section comprises a sleeve which can be expanded from a flat, stored condition to an expanded, generally elliptical shape adapted to receive top and bottom plastic sections to complete the container assembly. The plastic sections are molded to tightly receive the container body when expanded, with the plastic sections and the body being preferably maintained in such assembled position by suitable means such as adhesive bonding or the like.
A further object of the invention is to provide a container of the type described in which a dispensing lid is securely attached to the top plastic section and adapted to cover a dispensing opening formed in such top plastic section. In accordance with the invention, the dispensing lid is formed with a living" hinge, that is, a hinge formed by the material itself by reducing the transverse cross section thereof, with the dispensing lid being pivoted about an axis through such reduced cross section for uncovering the dispensing opening, and thereafter, when released, returning to a position covering the dispensing opening. The dispensing lid is preferably formed on the underside thereof with a closure stud which is received by the dispensing opening for 2 frictionally retaining the dispensing lid in a position closing the dispensing opening.
Yet another object of the present invention is to provide a dispensing container wherein the top and bottom plastic sections are molded so as to permit nesting of the containers, one on top of the other, in stable fashion. This permits neat and attractive stacking of the containers, with the stability provided by tne nesting arrangement reducing the likelihood of inadvertent tipping of the containers from the display shelves and consequent damage thereto.
These and other objects of the invention will be apparent from the following description in particular reference to the application drawing.
BRIEF DESCRIPTION OF THE APPLICATION DRAWING FIG. 1 is a top plan view of the dispensing container constructed in accordance with the present invention;
FIG. 2 is a vertical sectional view through the dispensing container, and
FIG. 3 is a bottom plan view of the container.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now in more detail to the application drawing, wherein like parts are indicated by like reference numerals, the dispensing container constructed in accordance with the present invention comprises a main body portion generally indicated at 10, and top and bottom plastic sections generally indicated at 12 and 14, respectively. In view of the interfittin'g relation-of the top and bottom plastic sections 12 and 14, respectively, with the main body section 10, the sections 12,
and 14 will be hereinafter referred to as the top and bottom plugs.
The main body section 10 is preferably of cardboard material and is in the form of an open sleeve which can be expanded from a flat, stored condition to a generally elliptical shape, as can be seen in the overall container configuration as illustrated in FIGS. 1 and 3.
The top plug 12 can be formed of any suitable material, such as polyethylene, polypropylene, propylene, or the like, with propylene being the preferred material. The top plug 12 is preferably molded in the shape thereof illustrated in FIG. 2, comprising a continuous outer peripheral wall 16 and a continuous inner wall 18 spaced therefrom to define a continuous slot 20. In the form shown, the top plug 12 is generally elliptical in shape, with the upper end 22 of the main body portion 10 being tightly received in the groove 20 when the body portion has been expanded to its elliptical shape as above described. Although the thickness of the body portion of the container and the width of the groove 20 are such that the body is snugly received within the top plug when these members are interfitted, the connection is preferably positively secured by means of adhesive or the like. This not only insures the retention of the members in assembled relation but prevents the entrance of moisture through the connection into the interior of the container.
The top plug 12 further comprises a generally flat top section 24 which merges with the exterior wall 16 at the periphery of the plug, and a raised portion 26 of generally truncated elliptical form, as seen in FIG. 1. The raised portion 26 permits nesting of superimposed continuous corner or bead 38 and the depressed section 36:
of the bottom plug define an elliptical-recess 40 slightly the top plug 12 to permit nesting of the containers as above described Referring to FIG. 2, it will be seen that the bottom 42 of the housing is received in the groove 34, with this connection being preferably sealed by adhesive or the like in the same manner as above described with reference to the interconnection of the top plug and the upper end of the container body.
The wall 24 of the top plug 12 is formed with a dispensing opening 50 and a plurality of relatively smaller, transversely aligned openings 52 for securely mounting on the top plug a dispensing lid generally indicated at 54. The latter is provided with a plurality of snap fittings commonly designated at 56 which are adapted to be snapped through the openings 52 for retaining'the dispensing lid in assembled position on the wall 24. It
tively moisture-proof assembly is provided, with the main body portion 10 being sealed at the interconnection thereof to the top and bottom plug members l2 and 14, respectively. The mounting of the lid 54 on the wall 24 of the top plug 12 issuch as to substantially eliminate the problem of moisture entering the interior of the container. To dispense the contents of the container, the dispensing lid 54 is raised by grasping the tab 64 to uncover the dispensing opening 50, after which the container can be oriented to gravity dispense the container contents in the desired amounts. The lid 54 larger in dimension than the projection 26 formed on i will be noted that each of the snap fittings 56, there being three in the form shown as well as three openings 52 therefor, are generally conical shaped at their leading ends, and are further formed with neck portions 58 which are received within the openings 52 when the lid connection, the plugs are preferably bonded, through epoxy adhesive or the like, to the main body section, with such adhesive serving also to seal the container interior from moisture. Prior to the assembly-of the top plug, the container can be filled and the dispensing lid 54 assembled on the top plug.
The contents of I the container can be dispensed quicklyand conveniently, with the shape of the container facilitating dispensing of essentially all of the container contents.
is assembled. The lid 54 is of course separately molded,
preferably from the same plastic materials above mentioned, with propylene being the preferred material. The resiliency of such material permits the snap fittings 56 to be pressed through the openings 52 for mounting and retention of the lid on the top plug 12 as above described.
The lid 54 further includes a closure portion 60 the enlarged end of which is slightly larger than the dis-' pensing opening to permit the lid to be retained in its solid, FIG. 2 position when the closure 60 is pressed through the dispensing opening 50. The closure 60 includes a neck'portion 62 which is disposed in the dispensing opening 50 when the lid is closed.
The lid 54 further includes a raised tab 64 to facilitate lifting of the lid to itsdashed line, FIG. 2 position, to expose the dispensing opening 50 for discharging the material from the container. The upper surface of the 7 tab 64 is in the same plane as the top surface of the raised portion 26 of the top plug 12 to stabilize the the provision of a groove 66 formed in the lid on the underside thereof, with the reduced cross section of the lid immediately above the groove serving as the pivotal axis for the lid when the same is raised as shown in dashed lines in FIG. 2. The resiliency of the materialis Through the provision of the top projection 26 and complemental bottom recess 36, the containers can be conveniently stacked one on top of the other, with comparative stability. The top surface of the tab 64 is at the same-elevation as the top of the projection 26 thereby serving to support a superimposed container at g both ends thereof thus eliminating any tendency of such superimposed containers totop or cant if otherwise supported solely by the projection 26.
Although propylene has been described as being the preferred material both for the top and bottom plugs and the dispensing lid, it will be understood that other suitable plastic materials could also be employed. It will also be understood that the cardboard from which the main body section is formed can be treated to improve the moisture resistent characteristics thereof.
