Definitions
- This invention relates in general to containers, and more particularly relates to plastic containers which are of the thin wall variety.
- Another object of this invention is to provide an economical plastic container of the aforementioned type which may be stacked and readily dispensed from a vending machine, being comparable in weight to present cup designs.
- Another object of this invention is to provide a container comparable in weight to containers heretofore known, but wherein the formed material affords a greatly increased apparent thickness of the container to thereby insulate the user from the temperature of the contents in the container.
- Another object of the invention is to provide a container as aforedescribed which is made of similar base material to prior art containers but, due to configuration of materials, is stronger per unit of weight than containers known heretofore.
- FIG. 1 is a fragmentary perspective view of a portion of the apparatus and materials being made by the process shown in FIG. 2;
- FIG. 1a is a fragmentary sectional View of the material shown in FIG. 1;
- FIG. 2 is a semidiagrammatic showing of the components of apparatus used in manufacturing the materials shown in FIG. 1;
- FIG. 3 is an isometric perspective view of the continuous molding roll used in the apparatus shown in FIG. 2;
- FIG. 4 is an enlarged fragmentary sectional view of a portion of the roll shown in FIG. 3;
- FIG. 5 is an isometric perspective view, a portion being in section, illustrating somewhat diagrammatically a container embodying principles of this invention
- FIG. 6 is a side view of the container shown in FIG. 5;
- FIG. 7 is a bottom view of the container shown in FIG. 6;
- FIG. 8 is an enlarged fragmentary sectional view of the upper portion of a container such as shown in FIG. 5 when made of the materials shown in FIG. 9;
- FIG. 9 is a fragmentary isometric perspective view of the material used in making the container shown in FIG. 8;
- FIG. 10 is a view similar to FIG. 8 when utilizing the materials shown in FIG. 11;
- FIG. 11 is a fragmentary isometric perspective view of the material used in manufacturing the article shown in FIG. 10;
- FIG. 12 is an isometric perspective view of an alternate type of material being manufactured by the general process shown in FIG. 2;
- FIG. 13 is a view similar to FIG. 12 of still another type of material usable in making containers embodying the inventive concepts;
- FIG. 14 is a semidiagrammatic isometric perspective view, a portion being in section, indicating diagrammatically the form of a container that is obtained when the material shown in FIG. 12 is used;
- FIG. 15 is a fragmentary sectional view of an upper portion of the container shown in FIG. 14 when a portion of the material shown in FIG. 12 is used in a nonlaminated form;
- FIG. 16 is a view similar to FIG. 15 showing the upper portion of the container when a laminated material such as shown in FIG. 12 is utilized;
- FIG. 17 is a semidiagrammatic view, of the apparatus utilized in the preferred method of molding containers from the materials shown in the earlier figures.
- Plastic containers have begun to come into general use with automatic vending machines and (particularly when associated with hot beverages such as coffee, soup, etc.) present a handling or holding problem to the user when the beverage is served hot.
- plastics used in manufacturing these containers have fairly good insulating characteristics per unit thickness when compared with other materials.
- relatively thin walls are required, since raw plastic material is uniformly sold on a per pound basis, and increasing of the amount or thickness of the material to increase the insulating qualities would merely increase the unit price of a plastic container to make it noncompetitive.
- One approach to the problem has been to try to extend the plastic material by foaming, i.e., creating bubbles of gas in the plastic material, and manufacturing a container of such foam material or manufacturing a laminate of foamed material to a thin web of non-foamed material.
- a first extruder of conventional design is shown diagrammatically in the lower right hand portion of FIG. 2 and is adapted to extrude a uniform web of thin plastic material 12 having a predetermined thickness and width.
- the plastic material is preferably polystyrene or a similar type of thermoplastic material.
- the web 12 is fed between a smooth roll 16 and a molding roll 14 (to be later discussed in detail) from which it emerges in the form which is shown in FIG. 1 and identified with the reference numeral 18. It should be noted that neither the width or length of the material is increased, but the apparent thickness is grealy increased.
- the material 18 is then either used as is or fed between two laminating rolls 20 and 22 and emerges as a laminated material 24 on the output side of the rolls 20 and 22.
- material which is to be laminated to the premolded material 18 may be conveniently extruded from a second extruder 26.
- the web passes between two rolls 32 and 34 which locate the web 30 for feeding to the area between the laminating rolls 20 and 22.
- the web of material 30 and the premolded material 18 are heated by a suitable heater 28 immediately adjacent the input side of the laminating rolls 20 and 22 so as to prepare the surfaces thereof sufliciently to obtain good cohesive bond therebetween in the finally produced material 24.
- Heater 28 may be an electrical resistance type of heater of any commercially known type or other suitable equivalent type heater, the main purpose being to soften the mating surfaces only, of the material 30 and the premolded material 18.
- the premolded material 18, or the laminated material 24, as it is received from the laminating rolls 20 and 22, may be wound on a suitable storage roll or may be fed directly into a container molding machine (shown diagrammatically in FIG. 17) as suitable and desired.
- the continuous molding roll 14 is shown in an enlarged fragmentary sectional view FIG. 4 and shown in perspective in FIG. 3.
- the molding roll 14 is generally cylindrical and on the outer surface of the periphery are a plurality of projecting lugs 38.
- Each of the lugs 38 have a generally planar rectangular end surface 40 and four tapering side walls 42, 44, 46 and 48 which taper inwardly in converging relation as they project from the surface of the roll 14.
- the individual lugs 38 may conveniently be formed by cutting away material from a cylinder to form a plurality of axially aligned longitudinal grooves 50 and transverse circumferential grooves 52. It will be appreciated that the fragmentary sectional view FIG.
- the molding roll 14 as it impinges upon the material 12 as it comes from the extruder 10 (in a heated condition), continuously molds a plurality of pockets 49 which are complementary in shape to the shape of the lugs 38. It should be noted at this time that extreme care must be exercised so that the lugs 38 on the molding roll do not have any sharp burrs or wire edges so as to tear the corners of the pockets 49 when the molding lugs 38 are withdrawn from the material as it passes thereby.
- the material 18 as it leaves the molding roll 14 has a smooth bottom surface 56 on one side of a base portion 54 and a plurality of projecting cross connecting webs 58 and 60 which correspond respectively to the valleys or grooves 52 and 50 in the molding roll 14. It will be noted that this premolding operation by the molding roll 14 increases the apparent thickness of the material as is shown by the relative thickness of the material 12 before it passes roll 14 and the thickness of material 18 after passing roll 14, best seen in FIG. 2 of the drawings. It is preferred that the preformed material 18, in cross section, presents web members 58 and 60 which are not less in height than the bottom wall or base portion 54 is in thickness.
- the molding roll 14 is mounted relative to roll 16 and the material 12, and the configurations and proportions of the lugs 38 on roll 14 are so arranged, that the material displaced by the lugs fills up the grooves 50 and 52 and the top surface of the cross webs 58 and 60 are parallel with planar surface 56 of the base portion 54.
- the increase in apparent thickness enhances not only insulation characteristics, but also increases the strength on a unit Weight basis.
- the stacking and vending problems of the containers are enhanced.
- the increase in apparent thickness increases the interference of special stacking rings where used, and under some circumstances allows elimination thereof.
- the container 62 is generally cylindrical in shape having a bottom portion 64, a short skirt portion 66, a radial shoulder 68 and side walls 70 which taper outwardly to a lip portion 72.
- the shoulder 68 on the interior or inner wall surface of the container is adapted to engage an external shoulder of a similarly configured container nested therewithin, the external shoulder being defined by the juncture between the bottom portion 64 and the side walls 70 of each container.
- the lines 74 and 76 are semidiagrammatic representations of the transformation of the cross webs 58 and 60 which define the pockets 49 in materials 18 and 24 as they are distorted to form new pockets 78 in the container molding operation by the method and apparatus shown semidiagrammatically in FIG. 17.
- each of the individual pockets 78 have the premolded forms shown respectively as 49 in FIGS. 9 and 11 respectively as applied to FIGS. 8 and 10.
- the material 18 when used to form a container 62, produces one having the outside appearance of a grid-like network of projecting interconnecting web members 74 and 76.
- the inside surface of the container 81] is relatively smooth.
- the outer surface of container 62 when manufactured from material 18 and when grasped by a user on the outside thereof, is such that the fingers of the user will be separated from the interior 80 by the dimension of the base portion 54 and by the thickness of the projecting portions 74 and 76.
- the ribs or webs 74-76 are relatively closely spaced so as to prevent direct contact by the fingers of the user with the base portion 54. Similar statements are true relative to the material 24 used in the manufacture of the articles shown in FIG.
- the material 31? may be very thin stock and substantially less than the thickness of the base portion 54.
- FIG. 12 of the drawings Another embodiment of material 82 is shown in FIG. 12 of the drawings.
- This material is essentially similar to that aforediscussed except that the cross or longitudinal ribs 60 have been eliminated and again this material may be used in the laminated form 83 or unlaminated form 85.
- the material 82 comprises a base material which has been premolded by a roll similar to roll 14 so as to have projecting lugs 86.
- a web of material 30 may be laminated to the top portions of the lugs 86 if desired to provide the laminated form. As shown in FIG.
- the material 32 when used to make a container 62 by the apparatus and method shown in FIG. 17 will assume a configuration as shown, and the lines 88 are semidiagrammatic representations of the distortion of the individual projecting lugs 86 of the material 82.
- material 82 is used in the laminated form (as shown in FIG. 16) it should be noted that the preferred method of molding the container assures that individual elongated compartments or pockets 92 are created by the lip 90 being pinched off in the molding operation (to be later described). By this method each pocket 92 between each pair of projecting ribs 88 is separated from adjacent pockets and from the atmosphere.
- the non-laminated material 85 when molded into a container, a portion being shown in FIG. 15, is essentially similar to that shown in FIG.
- the webs 88 necessarily strengthen the container on a weight to strength ratio. Further, it is possible to have a lesser amount of material in the container as compared to using material 18 with only a slight loss in rigidity. The close spacing of the ribs 88 prevents contact of the users fingers with the base portion of the material to increase the apparent thickness of the material.
- FIG. 13 Another type of material 94, usable in molding containers to increase the apparent thickness thereof, is shown in FIG. 13 and comprises a base portion 96 having cylindrical projecting lugs 98 which may be used as is in form or may have a thin web 30 laminated to the tops of the projections 98 as shown to form material 93.
- the lugs 98 increase the apparent thickness of the material 95.
- the strength advantage noted in previous forms is not as great.
- the material has been demonstrated to be quite strong per unit weight.
- the lugs 98 assume positions on the container corresponding to the points of intersection of the cross webs 74'76 of containers 62.
- the preferred method of molding is essentially that taught in my Patent No. 3,172,159 aforementioned.
- I have elected to show the material 18 (unlaminated material) shown in FIG. 1 of the drawings to illustrate the container molding operation.
- the apparatus 1% essentially comprises a storage roll 102 having material 18 wound thereon which is fed past a suitable heating means 104 into the molding apparatus per se wherein it is engaged on the upper and lower sides by an upper and lower clamp means 106 and 108.
- each of the clamp means 106 and 188 has an aperture 110 and 112 respectively, which are larger than the mold means 114 and mandrel means 116.
- the mold means 114 essentially comprises a male mandrel or plug member 118 and around the top portion thereof is a combination clamp and cut-off means which is discussed in detail in my co-pending application aforementioned.
- the mold 116 is essentially frusto-conical in configuration, and comprises side walls 122, a short radial shoulder 126, a short skirt portion and a knock-Out plug 130, the head of which is adapted, during the molding operation per se to be the bottom of the mold cavity.
- the bleed ports 132 which are placed adjacent the bottom of the short skirt portion 128. It will be noted that there are no other bleed ports in the side walls 122.
- the material 18 is clamped by the opposed clamping means 1064198, and the mold means 116 and mandrel means 114 are moved into telescoped relation, mechanically drawing the material down into the mold cavity. Thereafter, an air pressure differential is created so as to move the web from contact with portions of the mandrel member 118 to the mold side walls 122. At this time air is trapped between the shoulder 126 and the clamping edges of the mold lip 124 and the cutoff and clamp means 120 on the mold 118 so as to provide a resilient back pressure on the material adjacent the side walls 122 preventing the flattening out of the projecting web portions 58 and 60 of the material 18 during the molding operation.
- the material 18 is fed into the machine so that the projecting portions 58-60 (also true of projections 86 and 98) are those portions that engage the cavity side walls 122 in the molding operation.
- the projecting portions 58-60 also true of projections 86 and 98
- a thin wall seamless container made from thermoplastic material comprising, a hollow body member having a bottom wall and a peripherally continuous side wall extending upwardly therefrom which terminates in an open month, said container having a cross section throughout the peripherally continuous side wall which presents between inner and outer wall surfaces thereof a base portion of predetermined thickness, said base portion having uniformly distributed throughout its area a plurality of closely spaced, radially outwardly extending and integral projecting portions disposed on the outer side wall surface and being joined to each other by interconnecting means at points radially outwardly offset from said base portion to strengthen the container, said projecting portions extending outwardly by a dimension at least as great as the thickness of the base portion whereby the apparent thickness of the peripherally continuous side wall is increased to separate the container contents from a users hand by at least double the thickness of said base portion, said base portion throughout at least a major portion of its height being of uniform thickness with a smooth uninterrupted inner wall surface.
- interconnecting means comprises a plurality of web members similar in size and shape to said projecting portions and interconnected to said projecting portions in a grid-like network to define a plurality of closely spaced, discrete pockets.
- the container set forth in claim 2 including a sheet member of a predetermined thickness and of a like material secured to the ends of the projecting portions and web members.
- said interconnecting means includes a sheet member of predetermined thickness and of a like material secured to the ends of the projecting portions in spaced relation to the base portion to join the projecting portions to each other.
