Abstract
An all plastic container comprising the combination of injection molded pail and lid. The lid initially locks onto the container at upper and lower locations and seals thereto by virtue of an inverted U-shaped peripheral section with a segmented upper lock and a relatively continuously lower lock at the bottom edge of the lid skirt. The bottom lock can be torn away by way of a circumferentially weakened area that forms the lower edge of the skirt into a tear band. A starter tab is provided. Once the tear band is removed the segmented upper locks securely hold the lid to the pail. However, by lifting and flexing the lid at discrete locations identified by indicia on the top deck of the lid, the lid is relatively easily removed.
Description
- This invention relates to plastic containers of the type comprising a pail and a lid which sealingly fits onto the pail without the need for a gasket and further wherein the container combination has locking features which hold the lid onto the pail.
- Plastic containers comprising the combination of an open top pail and a lock on lid or closure are well known and have been in commercial use for shipping and merchandising various products in the United States for many years. They have largely supplanted metal containers in many areas including adhesives, food products and paint. The pail and lid are typically injection molded of a suitable polymeric material such as high density polyethylene or polypropylene. The seal between the pail and the lid can be achieved by providing a compressible O-ring gasket or by molding a notch in the top of the pail rim flange and providing a corresponding bead in the underside of the inverted U-shaped channel of the lid which receives the rim bead of the pail. This later structure is described in the published U.S. Application US 2002/0148846. Still another seal structure is illustrated in the expired patent to Richard Landis, U.S. Pat. No. 4,418,833.
- The present invention provides a container comprising the combination of an open top pail and a lid, both preferably made of injection molded plastic such as polypropylene, wherein a good seal is provided between the pail and the lid without the need for either a gasket or special features such as rim beads and notches in the top of the pail.
- In general, this is achieved by providing a pail with a flangeless top rim, and a lid having a narrow inverted U-shaped peripheral channel defined by an inner annular ring which is reinforced by radial ribs.
- In addition, and in accordance with a preferred embodiment of the invention, multiple locks are provided for securing the lid to the pail wherein said multiple locks comprise an upper lock made up of comprising a continuous bead on the outer wall of the container immediately below the top edge and a plurality of widely circumferentially spaced locking segments on the inside surface of the inverted U-shaped channel formed by the lid to provide widely spaced, discrete undercuts which receive the pail sidewall bead and lock thereto. The second of the multiple locks is provided lower down on the container sidewall and at the bottom of the outer skirt of the lid. This second lower lock is preferably removable by forming a circumferentially extending weakened area in the inside of the lid skirt such that the portion of the skirt below the weakened are can be torn away leaving only the upper lock in place. This manipulation is typically carried out by the end user.
- In the preferred from the upper lock is provided in two, three or four discrete and circumferentially spaced areas and indicia are carried on the top surface of the lid to show where the locking segments are located and to direct the user to apply a lifting force in that area to remove the lid from the container once the tear band has been pulled away. In the illustrated embodiment, there are three such indicia in the forms of arrows with the legend “LIFT” molded into the top deck of the lid thereby to eliminate the need for a printing function or the application of a decal. However, both of these alternatives as well as other alternatives, while not preferred, are useable in accordance with the more detailed aspects of the present invention.
- Other applications of the present invention will become apparent to those skilled in the art when the following description of the best mode contemplated for practicing the invention is read in conjunction with the accompanying drawings.
- The description herein makes reference to the accompanying drawings wherein like reference numerals refer to like parts throughout the several views, and wherein:
-
FIG. 1 is a perspective view of an all plastic injection molded container comprising a pail and lid embodying the invention; -
FIG. 1A is a perspective view of theFIG. 1 container with the lid removed; -
FIG. 2 is a plan view of the inside surface of the lid from the combination ofFIG. 1 ; -
FIG. 3 is a plan view of the outside or top surface of the lid ofFIG. 2 ; -
FIG. 4 is a side view in section of an enlarged portion of the lid and pail showing how the upper and lower locks are formed; -
FIG. 5 is a side view in section showing the upper and lower locks engaged; and -
FIG. 6 is a composite of side views in section showing how containers stack on one another. - Referring to the Figures there is shown an all
plastic container 10 comprising the combination of a tapered cylindricalplastic pail 12 and an injection molded lock-onplastic lid 14. In this illustrative embodiment thepail 12 andlid 14 are both injection molded of polypropylene but other materials such as high density polyethylene may be used as alternatives. - The
pail 12, which in this instance is a 3½ gallon pail but can be made in a variety of other sizes, comprises a taperedcylindrical side wall 16 extending upwardly to an enlargeddiameter collar 18 which is integral with thewall 16 and lies below theupper rim portion 26 as best shown inFIG. 1A . The collar runs circumferentially around the entirety of thepail 12 and has diametricallyopposite ear portions 20 which receive awire bail 22 having a ferrule typeplastic handle 24 mounted thereon. - As shown in
FIG. 1A theupper rim portion 26 of theopen top container 12 is featureless; i.e., it has no notches, flanges or beads at the upper end. However, approximately ½ to ¼″ below theupper rim portion 26 and on the outer surface of theside wall 16 is abead 28 which is circumferentially continuous around thepail 12 and forms part of an upper lock to be described. Approximately 1″ below thebead 28 is a second radially outwardly extendingbead 30 which is preferably notched at six or eight evenly spaced locations and is integral and contiguous with the radiallyoutstanding collar 18. Reinforcingribs 32 are provided at circumferential intervals of about 1⅛″ around the pail. - Looking at the
lid 14, it comprises an inverted U-shapedperipheral channel portion 34 defining a downwardly opening and radially narrow,internal channel 36 which snugly and sealingly receives thetop rim portion 26 of thepail 12 therein. The inverted U-shaped channelperipheral portion 34 comprises anouter wall 38 and a downwardly extending annularinner wall 40 having circumferentially spaced reinforcingribs 42 as shown inFIGS. 2 and 4 . The lid has arecessed deck 44 with thetapered lead surface 46 from theperipheral channel portion 34 to make it easier to stack one of the containers on top of another of like size and design. - In accordance with the invention, an upper lock comprises the combination of the
bead 28 on thepail side wall 16 and three evenly circumferentially spacedlocking segments 48 forming undercuts 50 on the inside surface of theouter skirt 52 of the lid. When thelid 14 is firmly attached to and seated on thepail 12 thebead 28 fits within the undercuts 50 of the threelocking segments 48 to hold thelid 14 on thepail 12. - Further in accordance with the invention,
indicia 58 comprising the combination of outwardly directed arrows and the legend “LIFT” are molded into the top surface of thedeck 44 to indicate exactly where thelocking segments 48 are located such that a user of the pail may apply a lifting force in this area after the removal of thetear band 52 has been achieved as hereinafter described. Similar equivalent legends may be used. - The lower skirt portion of the
lid 14 comprises the dependingskirt 52 terminating anundercut 54 which fits over and receives thebead 30 on the lowerlocking collar portion 18 of thepail side wall 16 when thelid 14 is placed onpail 12 and firmly seated. However, a circumferentially extending weakened area provided by a notch 56 allows the lower portion of theskirt 52 to be torn away. Astarter tab 60 is provided as shown inFIG. 1A in a cut-out area 62 for the purpose of facilitating the removal of the tear band formed by theskirt 52 so as to eliminate thelower lock - In operation, the
pail 12 andlid 14 are typically injection molded at a suitable plant site. Once they are shipped to the customer, thecontainer 10 is filled with product (not shown) and thelid 14 is seated on thecontainer 12 such that theupper rim portion 26 of the container side wall extends fully and contactingly into thechannel 36 and is sealed by the tight fit therein. There is a contact seal on both sides of thesidewall 16. Theupper lock 28, 50 snaps into place and thelower lock lid 14 on thecontainer 12.Similar containers 10 can be stacked and shipped in the product filled condition without fear of leakage or the ingestion of unwanted air into the interior of thecontainer 10. - When the user is ready to gain access to the product, the
starter tab 60 is broken away from thelid portion 52 and the tear band portion ofskirt 52 is removed. This eliminates thelower lock container 10 has been opened. Once the tear band portion ofskirt 52 and thelower lock lid 14 to thepail 12 are the upper threelocks 28, 50. These locks are relatively easily overcome without the use of tools by lifting the revealed edge of thelid 14 immediately adjacent theindicia arrows 58. The polypropylene pail and lid combination is sufficiently flexible to permit the lidrim channel sidewall 38 to be flexed outwardly in this overcomes the lock and permits thelid 14 to be removed from thepail 12.
