7 Claims.

This inventionrelates to containers of a type adapted. for use as candy pails, butter tubs and. the 1ike and its purpose is to provide a uniform construction and a new method. of manufacture a;adapted to overcome num'erous difimulties which have heretofore been met in the manufacture and use of containers. It is frequently necessary to remove-the covers cf candy pails, butter tubs and the 1ike for the purpose of inspecting the 10 contents, after which the covers .must be replaced unti1 the contents of the containers are ready for useand 1:his requires a form of construction Which will permit 0f removal of the covers without injury thereto or 1:0 the means by which they are secured in place. Most fastening devices for pail covers have heretofore been of a type which required their destruction 01 deformation in removing thecover and it has been impossib1e to replace covers with the same security that guthey possessed at the time that the containers were originally packec1. The principal object of the present invention is 110 provide a new form of container having an annular rim adapted 1:0 interlockwith the cover and having parts capa* b1e of relative movement with respect to the body portion of ehe rim to permit the cover t0 be removed and. restored when desired. A further object of the invention is 110 provide an improved container' comprising an integral rim having iparts' adapted to be deformed to project over the cover to hold it in place. Still another object 0f the invention is to provide an improved method of forming a container according to.

bination with an annular metallic rim havingv an inwardly projeccing flange along its lower 5 'edge 120 engagesaid groove and an annular bead. alongits upper edgewith longitudinal s1its at inter vals beneathsaid bead, whereby portions of saidbead may be bent inwardly t0 overlie a cover seated on th upper end of said. vessel. 5o Other objects relate to various features of comstruction-and. arrangementwhich will appear more f1'1'113f hereinafter.

The natura cf the invenoion will be understood. from the following specification taken 5With the accompanying drawings in which one form of the improved container is i11u'strated in c0n11ectioziwith one method of forming it.

In thedrawings; Fig. 1 is a perspectiveview cf the improved container of"the present:invention with a part 0 Fig. 1 With the cover thereof in the positior'1' 7o'-" Which it oc'cupies before being' passed. down-' Wardl37 within the annular rim;'

Fig. 5 is a partial vertical sectibn similar to that of Fig. 4 show'ing the'relative positionsof the*parts after the cover has been put in p1ace 011 the upper edge of the vessel within the rir'h and -after portions 0f the rim have' been bent inwardly to overlie the cover;

Fig. 6 Shows a perspective view 'of a portion' of the sheet met'al strip on which ehe annular 30 metallic rim is formed;

Fig. 7 is a perspective view of aportionof thte" annular metallic rim which is form6d )I1 the sheet metal blank illustrated in Fig. 6; and.

Fig. 8'is a perspective view of the end p 01'1-35 tions of the annular metallic rim before"these' parts have been overlapped and. united Wii;heach other'.

As illustrated in the drawings, the inv nti0n comprises a vessel 10 havihg an annular wal1 11 which may be flared upwardly from if:s lower edge and which is formed preferably Cf wood or Wood veneer. Ihe ring 12, formed of wood'or" other suitab1e material, is secured around the inside of thewvall 11 adja zent its lower edge' 9 and this ring forms a ledge on which is seated ehe circular bottom Wall 13 of the vessel. Around. the upper edge of the vessel- 10, there is secured an annular metallic rim 14 Which is adap-ted to secure in place the' circular cover- 15 Which may preferablybe formed of wood or w0od veneer andwhich has an annulanfiange 15 adapt ed to seat upon the top edge -surface" 11a of the-annular wall 11 withfiheannular shoulder 15 of the cover extendirig dovvnwa'rolly Within thewall ofthe vesseL-aSshow1iin-Fig5fi 'Ihe annular Wall 11 of the vessel is provided on its outer side, and near its upper edge, with an annular inwardly extending groove 11 which is adapted. be engaged by an annular flange 1 6337 60 the rolls.

14 fornied alo'ng the lower edge of the rim and preferably united with the body portion 14 01 the rim by means of an annular outwardly extending bead 14 which is provided primarily for 5 the purpose 0f adding strength to the rim so that it may more effectively hold the annular wall 11 in auch shape that; lt has a true circula'r cross section. The body portion 14 0f the metallic rim is flared upwardly to a slight extent 10 to correspond with th e flare of the wall 11.

This flare may be imparted to the rim by driving lt on to the vessel 10 from the bottom thereof until the flange 14 snaps into engagement with the groove 11, with the result that the 15 rim is flared to fit closely against the Wall of the vessel. When the rim reaches this final position on the vessel, it projects above the top edge surface 11 of the vessel and this projecting portion is adapted to receive within it tl1e circular cover 15.

The rim 14 is provided around its upper edge With an annular outwardly turned bead 145 which is preferably a complete bead having a substantially circular cross section. At intervals ;aroun d the circumference of the rim 14 the body portion 14 thereof is provided With longitudinal slits 14 which are located just beneath the lower margin of thebead 14 and in a plane just above the upper surface of the cover 15 when -:the cover is seated on the vessel as shown in Fig. 5. After ehe cover has been moved downwardly within the rirn 14 from the position sh own in Fig. 4 to the position shown in Fig. 5, the portions of the bead 14 which lie above the slits 14 are bent inwardly to form projections 14 which overlie, and preferably contact with, the upper surface of the cover 15 so that they secur ely hold the cover in place on the ve ssel. It will be apparent that these projec- 401 tions 14 may be bent inwardly by a pair of pliers or any other conventional tool and that,

when the contents of the vessel are 120 be inspected, these projections may be bent outwar dly to permit the removal 01 the cover, after which the cover may be restored and theparts of the rim above the slots again p11shed inwardly 110 hold the cover in place.

The rim 14 is preferably formed from an elongated strip 14 of steel or the like which is -comparatively hard and stifi, although having sufiicient ductility to permit th formation of the bead s 14 and 14 This strip is run through suitabl6 rolls or the like which form the beads 14 and 14 thereon While at the same time forming the flange 14 which projects inwardly beyond the inner surface of the body portion 14 of-;the resulting rim. The slits 14 may also be formed by suitable shearing blades o1 the like 5 showl'l in Fig. 8, to form projecting tongues 14 which areadapted to overlap the body portions 14 of therim when the ends of. the beadsare vloroughttogether, as illustrated in Fig. 1. The

overlapping end nortions of the rim may then- ::"b8 secured together by means of spot welds 01 rivets 16. The annular rim is then formed and is in readiness 110 be applied to the vessel 10. Although one form of the improved container and one method cf constructing it have been shown and described by way of illustration, it will be understood that the invention may be constructed in various forms and that the improved method may be practiced in various ways Within the scope of t he appended claims.
