Description
March 26, 1963 K. GELPEY A 3,082,867
COMPARTMENTED PACKAGE AND DIVIDER THEREFOR Filed April 1o. 1961 INVENToR. KEN N ETH GELPEY ATTORN EYS This invention relates to a disposable package sui-table for containing and mixing a plurality of components and more particularly to a compartmented package comprising a sealed bag which is divided into two or more leak proof compartments by one or more removable divider assemblies.
Heretofore it has been considered desirable to produce an inexpensive multi-compartmented package for separately containing a plurality of components which can be readily converted into a single compartment bag within which the components can be mixed together Without exposure to the air or to the hands of the user. This type of bag is especially useful for packaging chemicals which when mixed together Will rapidly react to form a composition that must be used within minutes or else be useless. Thus, for example, one compartment may contain a fluid thermo-setting resin such as an epoxy resin and another compartment may contain a curing agent therefor such as an amine. When the two materials are mixed together, the resin will rapidly set up into a mass of hard, durable heat-resistant plastic. The mixture must be used before it becomes hard; otherwise it is worthless. Having the two ingredients in separate compartments of a single package is desirable since it facilitates selling them as a unit while at the same time keeping them separated so as to avoid premature setting up of the resin. Moreover, having them in separate compartments of a bag which is capable of serving as a mixing container without the components being exposed tto the air or to the users hands, is not only convenient and unmessy but also assures that the materials will be mixed in the proper proportions.
The generally accepted approach has been to form one large dat bag of flexible material and to divide it into two compartments by means of a clamp-type divider, with one of the essential components stored in one compartment and the other of the essential components stored in the other compartment. Various types of clamp-type dividers have been devised. Some of them have been made of metal; others have been made of plastic. However, none of them has been satisfactory. For one thing, none of them (and particularly those made of plastic) has been capable of providing an effective seal between the two compartments, as a result of which some of the material in one compartment would leak into the other compartment to prematurely initiate the chemical reaction. Not only are such packages unsaleable but also they have created doubt as to the feasibility of marketing different reactive materials in a single plastic package. Another criticism of clamp-type dividers has been excessive cost, particularly in the case of metal dividers. Still another criticism is that they have prevented the bags from lying flat, thereby making it difficult to stack them neatly in boxes for shipment or for display. In certain other cases, the dividers have been dicult to apply and just as diicult to remove.
Accordingly, a primary object of the present invention is to provide a novel package divider which is free of the disadvantages and defects attendant to dividers heretofore available.
Another primary object of the present invention is to provide a flexible bag which is selectively and temporarily divided into a plurality of hermetically sealed compartments by means of a novel removable plastic bag divider.
rates tent A more -specic object of the present invention is to provide a divider or closure assembly for a flexible bag which comprises an elongate core member and an elongate clamp member between which the bag is clamped; the elongate core consisting of a relatively resilient plastic material and the clamp being constructed of a relatively stiff plastic material, the core and clamp having complementary mating sections which pinch together tightly the walls of the bag along different transversely extending areas of the bag.
Other objects and many of the attendant advantages of the present invention will become readily apparent from a study of the following detailed specification when considered together with the accompanying drawings wherein:
FIG. 1 is -a plan view of `a multi-compartment package embodying the present invention;
FIG. 2 is an enlarged cross sectional view taken along line -Z of FIG. 1; and
FIG. 3 is an enlarged exploded perspective view of the two elements which make up a divider assembly embodying the present invention.
Referring now to FIG. l, there is illustrated a substantially flat bag 2 which is of any suitable rectangular shape and which is preferably formed from exible sheet plastic material such as polyethylene or polymerized vinylidene chloride. However, other well known sheet plastic material may also be employed without departing from the principles of the present invention. Moreover, the bag may be formed from extruded tubing instead of from `sheet material. Preferably, the bag material is transparent or translucent.
This type of bag may be formed from two different Webs of sheet plastic material. Preferably however, it is formed by taking a single web of plastic material and folding it along its longitudinal center line which is represented by the edge 4 of the bag. On folding the web into tWo sections of equal width, its longitudinal edges will overlie one another. These edges are sealed together as indicated at 6. At this point, the web is in the shape of `a flattened tube and comprises a front wall 8 and a rear wall 10 (FIG. 2). Thereafter, the bag 2 is formed by sealing the tube transversely as indicated at 12 and 14.
This type of bag is well known and is manufactured and filled at a relatively high rate on any one of several types of well known packaging machines.
In the practice of the present invention it is contemplated that the bag 2 will be filled with two different materials and that these materials will be retained in separate compartments 16 and -18 which are formed by subdividing the bag 2 by means of a divider assembly indicated generally at 20. The complete package of FIG. 1 may be made according to two different procedures. According to one procedure, after the first seal 112 has been made, the bag is iilled with material in a predetermined quantity which is insufficient -to ll more than a given amount of the bag, e.g., about half. Thereafter, the divider assembly 20 is applied to the bag so as to divide off the unfilled portion of the bag from the illed portion `of the bag. Thereafter, the unfilled portion of the bag is lled with another material, after which the second seal 14 is made. At this point the bag is as illustrated in FIG. l, comprising ingredient A in compartment 16 and ingredient B in compartment 18. The alternative procedure is to apply the divider assembly first, fill and seal at one end and then fill and seal at the other end.
FIGS. 2 and 3 illustrate in detail the divider assembly of the present invention. This novel divider assembly is adapted to hermetically seal off chamber I16 from chamber 18 while at the same time allowing the bag to lie at. T-his facilitates stacking a plurality of the bags in a box or carton.
The novel divider assembly 20 comprises a core member 24 land a clamp member 26. The core mem'ber 24 may be formed of any suitable plastic material. However,.it should be resilient in order to function as contemplated by the present invention. The clamp member 26 also is formed of plastic, `but it must be relatively sti in order to `attain the proper result. Preferably, the dilference in stiffness `between the two elements is attained by manufacturing one member with less plasticizer than the other member. Alternatively, the two members may fbe made of diflerent plastics, one of which is relatively rigid while the other is relatively ilexible.
The core member 24 is essentially of T-shaped cross section. It comprises a base portion 28 having on one side a longitudinally extending rib 30 of Ceshaped crosssectional profile. The side of the base portion 28 on which is located la rib 30 is divided into two flat substantially co-pl- anar surfaces 32 and 34 which are integral with but extend laterally of the surface 312 of the C-shaped rib 30.
The clamp member 26 has a flat underside which is divided into two tlat substantially co-planar longitudinally extending surfaces 40 and 42 which are separated from each other by a longitudinally extending groove 44 which also is of C-shaped cross-sectional conguration. Groove 44 is sized and shaped to complement rib 30 of the core, with clearance being `allowed between them to accommodate the thicknesses of the two walls 8 and i0 of the bag 2. The width of clamp member 26 is substantially the same as the width of the base portion 28 of the core member. Therefore, the surfaces 40 and 42 of the clamp member are in opposed facing relation with the coplanar surfaces 32 and 34 of the core member when the two members are in mating relation to each other.
FIG. 2 illustrates the vrelationship between the core 3 and the opposed sides 8 and 10 of the bag 2. The clamp member 26 is lirst positioned on one side of the bag, the bag being tipped so the commodity A will ilow toward one end, in this case toward transverse seal :12. Thereafter core member 24 is applied on the other side of the bag. The clamp and core are snapped into mating relation with each other, causing the opposite sides of the bag to be sandwiched tightly between them. The two sides of the Ebag are pinched together to form a :tight fluid seal which prevents commodity A from leaking out of the newly formed compartment i6. For clarity of illustration, a slight space is provided in FIG. 2 'between the center portion of the clamp member and the adjacent sandwiched portion of the bag.
It is to be observed that the maximum width of rib 30' is substantially equal to or slightly greater than the -rninimum width of groove 44. Accordingly, lin order for member expanding again as the widest part of the rib passes the nari-cwest part of the groove. The difference between the maximum width of groove 44 and rib 30- should 'be less than four `times the thickness of a wall of the bag. As a result, portions of the `walls of the bag will 'be squeezed tightly on opposite sides of rib 30.
Since the sur-faces 40 and extensive with the surfaces 32 tions 48 and 50 of the bag 2 are effectively pinched together tightly between the core member on opposite sid-es of rib'30. Since the rib is of C-shaped construction, with its sides 52 and 54 dii/erging Iaway from |base portion 28, the walls of the bag, at the junctures of rib 28 With the surfaces 32 and 34, are bent back at an angle greater than 90 (please see FIG. 2).
. In all the walls of the bag are bent sharply four times within the limits determined `by core and clamp members. InA other words, commencing with the bag section 48 which is pinched between the surfaces 32 and 4), the Walls of the bag are bent back through an angle greater than up along side S2 of the rib 3%, then they are bent sharply once more so as to follow the topy curvature of nib 30, then they are bent back through another angle greater than 90 down along side 54 of ri-b 39, land then they are bent back again Athrough another angle greater than 90 lbetween surfaces 34 and 42. Because of this multi-bending of the Walls of the bag, plus the .fact that the walls of the bag are clamped together tightly along the `sides 52 and 54 of the rib and Ibetween the flat surfaces of the two members, the two chambers 16 and 18 of the bag are effectively fully sealed off from each other so that no iluid can llow or otherwise migrate from one compartment to the other.
Furthermore, since the surfaces 32, 34, 40 and 42 are :dat and may be considered to reside in substantially the same plane, the two sections of the bag can lie flat and substantially in the same plane. This permits the compartmented bag or package to be packed in boxes with little or no trouble. In this connection it is to be noted that the overall height of the divider unit (as seen in FIG. 2) is only negligibly greater than the maximum thickness of the package. This facilitates packing the bags in boxes in relatively flat layers.
In the practice of this invention it is preferred that the and the complementary surfaces 40 core member and clamp 5/8 inch. the two elements out of being manufactured.
Application of the clamp and core members to the package is relatively easy and can be ,-done rapidly with a simple press. Manual force is sufficient to readily separate the two members. Once the two members have been separated, the material A can be mixed with ma- In the latter case, the closure element would be used to retain unused material in the bag Where the material is of a type which will still be useable at a later time.
In View of the foregoing description and the .accompanying drawings, it will be seen that the several objects of the invention are achieved and that other advantageous results are attained.
Accordingly, since changes may be made in the illustrated construction without departing from the spirit of the invention, it is to be understood that the foregoing detailed description has been given primarily to facilitate understanding and that it should be interpreted as illustrative and not in a limiting sense since various modifications will be obvious to persons skilled in the art.
