- FIG. 4 38 Reissued Dec. 23, 1975 Sheet 2 of2 Re. 28,658
- This invention relates to disposable containers and lids made of plastic, and more particularly comprises a new and improved insulated disposable container and lid made from foam plastic sheet.
- the invention has particular application in the manufacture of containers in the half gallon and larger range.
- An object of this invention is to provide a simply constructed tub made of foam plastic which has very high insulating properties.
- Another object of this invention is to provide a dis posable insulated container whose side walls may be embossed or otherwise treated as part of the assembling operation for decorative or advertising purposes.
- Another object of this invention is to provide a large disposable tub which is moisture proof and grease proof and which is suitable for the packaging of hydroscopic materials.
- Still another object of this invention is to provide a disposable insulated tub which is suitable for use as an ice bucket and whose mouth is sufficiently rigid to allow the bucket to be used as a scoop to gather ice cubes from a chest.
- this invention is embodied in a tub made of expanded foam plastic sheet. While the invention is not limited to containers of a particular size and has application to both large and small containers, in accordance with one embodiment typically the sheet may be approximately 12. inch thick and having a weight of approximately 19 grams per square foot.
- the container is made in two parts, namely, a side wall blank which is sealed along a side seam and a preformed bottom having a skirt which abuts against the bottom of the side wall and is sealed to it.
- a separate cover or lid may be provided, which has a snap fit over the mouth of the container, and the lid is provided with slits that enable vent openings to be formed in it.
- FIG. 5 is a detail view of the rim of the tubs of FIGS. 1 and 2;
- FIG. 6 is a fragmentary cross-sectional detail of the tub of FIG. 2 and showing how two such tubs nest;
- FIG. 7 is a plan view of the lid of FIG. 3;
- FIG. 8 is a fragmentary cross sectional detail of the lid showing how a vent opening is formed in it;
- FIG. 9 is an enlarged fragmentary cross-sectional view taken along the section line 9-9 of FIG. I.
- FIG. 10 is an enlarged fragmentary detail view show ing the way the lid fits on the container rim.
- the bucket 10 shown in FIG. 1 has a side wall 12 and a bottom 14.
- the side wall 12 may be made from a blank having curved and parallel top and bottom edges of conventional form and with diverging side edges so that when the side wall is rolled into the container shape it is frustoconical with the desired side wall taper to facilitate nesting.
- the side wall 10 along with the bottom 14 are made from generally rigid expanded styrene sheet of approximately .I I2 inch in thickness and weighing 19 gram per sq. ft. with a cell size of4 to 5 mils. It is to be understood that these dimensions are not limitations to the scope of this invention.
- the side edges 16 and 18 of the side wall 12 are overlapped as shown in FIG. 9, compressed, and sealed together to form a liquid tight seam running from top to bottom of the side wall when it is formed.
- the total thickness of the overlapped portion 20 of the side wall is less than twice the stock thickness and preferably does not exceed substantially the single stock thickness of the material.
- the bottom 14 of the container is preshaped before assembly with a generally flat central portion 22 and a skirt 24 which extends downwardly from the central portion 22 generally with a downward flare of approximately 3.
- the flare of the skirt is in part determined by the angle of the side wall 12.
- the outer diameter of the skirt 24 at the bottom edge 26 is equal to or slightly larger than the inner diameter of the bottom edge 28 of the side wall 12 so that when the bottom is assembled as shown in FIGS. 1 and 4 the outer surface of the skirt 24 at its lower edge 26 engages the inner surface of the lower margin 28 of the side wall. This relationship is particularly evident in FIG. 4 where the bottoms of two containers are shown in their nested relationship.
- the lower edges are heat sealed together in a manner shown in FIG. 4, and the mating surfaces of the skirt and lower margin of the side wall fuse through a height of approximately one thirty-seconds inch. From that point, the skirt and side wall diverge in an upward direction to form a well 30 which is particularly desirable as a grease trough when buckets are used to contain fried foods such as chicken.
- the height of the skirt 24 measured from its lower margin to the upper surface of the central portion 22 is approximately l3/l6 inch. and the trough therefore has a height of approximately 25/32 inch. Its volume is of course also a function of the taper of side wall [2. Typically it may be l2".
- the trough has substantial volume to accommodate grease or other substances which are given off from the material packaged in the tub.
- the rim 34 is turned over as shown in FIG. 5 to form a semi-rolled lip and preferably the material of the rim is somewhat expanded so as to increase its stiffness.
- the application of heat to the sheet material when the rim is rolled to form the configuration illustrated may be utilized to expand the sheet material to the desired thickness.
- FIG. I nests as shown in FIG. 4 on the bottom I4.
- the inner corner 38 of the lower edge 26 of the skirt of the upper container rests on the outer radius 40 which joins the skirt 24 to the central portion 22 of the bottom.
- the pitch or stack height may be approximately *4 inch, and the side walls of adjacent containers will be held apart slightly and the rims of adjacent containers will be separated sufficiently to allow for ready separation of the containers.
- the container shown in FIG. 2 differs from the container of FIG. 1 in the construction of the bottom.
- the container 50 has a side wall 52 with a semirolled rim 54 identical to that-of FIG. I, but the bottom 56 is distinctive.
- the bottom includes a generally horizontal central portion 58 which may or may not be bowed upwardly as shown in the drawing to resist sagging, and the bottom also includes a peripheral skirt 60 which extends upwardly from the margin of the central portion 58.
- the skirt 60 is upwardly flared so that it forms the same angle with the vertical as does side wall 52. Typically this flare may be an angle of 12.
- FIG. 6 the details of the connection between the skirt 60 and side wall 52 are shown.
- the bottom 56 is preshaped in the form shown in FIGS. 2 and 6. and the axial extent of the skirt 60 is substantially the same as the skirt 24 in the embodiment of FIG. I.
- the skirt 60 is heat sealed to the inner side of the side wall 52 of the container, and the bottom 62 of the side wall is wrapped about the radius 64 which joints the skirt 60 and the wall 58 so as to form 1 smooth juncture between the side wall of the container and the bottom.
- the lower edge 62 of the side wall where it wraps about the radius 64 is compressed so as to form a smooth union between the outer surface 66 of the side wall and the lower surface 68 of the aottom 58.
- the lid shown in FIGS. 3 and 7 to I0 is made of the same material and has substantially the same stock thickness as the containers of FIGS. 1 and 2.
- the container lid I00 includes a top wall I02 and a downwardly extending skirt I04.
- the skirt I04 is provided with an Jndercut ring 106 accentuated on its inner surface 108, which is adapted to engage the lower end 110 of the rolled rim 34 of the container so as to retain the lid in place over the container mouth. as illustrated in FIG.
- the underside of the lid, in the juncture of the central portion and the skirt is contoured to mate snugly with a portion of the cross-section of the rolled rim 34 of the container.
- the lid is provided with four upstanding bosses 112 in the top wall 102, which serve several functions.
- the outer edges 114 of the bosses I12 are each curved as is clearly shown in FIG. 7 so as to substantially define a circle.
- the bosses are adapted to fit within the skirt 24 of a container bottom stacked above it and retain that upper container in place. That is. the curved sides 114 of the bosses will prevent the upper container from slipping sideways on the top.
- the bosses 112 are provided with a diagonal cut 116 which allows a portion of the bosses containing it to be bent inwardly as shown in FIG. 8 to form a vent opening 118. That is, the cut I16 forms a flap in the top wall of the boss, which flap may be bent downwardly as shown in FIG. 8 to open the top of the boss. It will be appreciated that when the flap 120 is left in the formed position as in FIG. 3, the lid I00 forms a seal for the container, but when the flaps are folded downwardly as suggested in FIG. 8, the interior ofthe container is vented. Even when the flaps 120 are bent so as to form the vent openings I18, they do not interfere with the container which is stacked above when in fact several containers are placed one above the other.
- vent openings 118 are of sufficient size so that the fingers may be inserted through them so as to provide a convenient handle to carry the bucket.
- the vent openings not only perform their main function of venting the contents of the container but also form a handle for the convenient carrying of the package made up of the container and lid.
- the containers and lid of this invention will be appreciated to have many advantages over prior art containers.
- the containers may have any cross sectional shape as the bottoms are pre shaped and the entire container is made of plastic.
- the preshaped bottom may be either formed by thermoforming techniques such as pressure or vacuum forming, or it may be shaped by matched molds which work on the sheet. Because of the nature of the material used. both the bottom and top may be heat sealed.
- the bosses 112 provided in the container lids not only facilitate stacking of filled containers, but they further facilitate stacking of the lids themselves. When the empty lids are stacked one on top of the other, the bosses 112 will cooperate with the skirts 104 to retard accidental slicing" of the lids horizontally from a stack.
- vents in the bosses provided by the slits form not only vents but gripping means as well.
- the vent sizes may be varied by changing the angle of the bent flaps.
- the vent flaps may be bent up or down, or even be torn off if desired.
- the vents are particularly desirable when the containers are used for chicken or other hot foods to allow the steam given off by the food products to escape. In this way the contents are kept relatively dry as the steam given off by the food will not tend to make the contents soggy.
- bosses I12 allow the slits to be formed horizontally in them by a horizontal blade as the lids are moved horizontally below it.
- the lid may be trimmed from its web by a horizontal blade, and the arrangement may be used for lids of different diameters with altering the arrangement.
- the grease trough provided in the embodiment of FIG 1 further allows the contents to drain so that the food itself does not stand in the grease which drains from it.
- the side wall material may be selectively expanded so as to provide raised or embossed lettering in the side wall for advertising for decorative purposes.
- a bucket formed of the material identified is moisture proof and grease proof and is suitable for storing hydroscopic materials.
- the relatively stiff rim allows the container to scoop hard materials such as ice without becoming mutilated.
- the containers are suitable for use with the lid of FIG. 3, it will be appreciated that inside fitting lids could also be used with them.
- the foam material may be combined with other materials such as an open web-like fabric or a film for added strength or texture.
- a container comprising:
- a wrapped side wall made from generally rigid foam sheet material having a lapped side seam, defining openings at opposite ends thereof;
- a preshaped bottom wall made from generally rigid foam sheet material said bottom wall having its central portion lying generally perpendicular to the axis of the side wall and an annular shirt extending I away from the general plane of the] outwardly of said central portion into proximity with one end ofsaid side wall.
- said skirt defining an outer diameter [slightly 1 no less than the inner diameter of I: one of] the said opening [s] in said container at said one end ofsaid side wall whereby said bottom wall may be fitted snugly into said opening at said one end of said side wall;
- a container as described in claim 1 further characterized by said side wall being frustoconical in shape and nar rower at the bottom edge and said skirt being frus toconical in shape and being wider at the bottom and with the upper edge of the skirt joining the central portion said heat-sealed seam joining only the lower portion of the skirt and the bottom margin of the side wall and with the side wall and skirt diverging from one another in an upwardly direction.
- a container as described in claim I further characterized by said side wall being turned over at the upper edge to lend lateral stiffness to the container.
