The present invention relates to containers of the type having a flexible fibrous body portion constructed of a material such as paper board or "the like, and has particular reference to an g improved top construction in which a metallic rim portion is secured to the container when the latter is' set up or erected.
-A principal object of the invention is the provision of a flexible fibrous container having an 10 improved metallic rim portion secured about its upper edge. A
An additional object is the provision of a container having a flexible fibrous body portion provided with ,a strip secured adjacent its upper is edge and an improved metallic rim member loosely fitted over the upper edge of the body portion and the strip in such a manner that one portion of the rim member fits beneath the strip to prevent vertical displacement of the rim and 20 a channel portion of the rim member secures the body portion oi, the container against inward flexing.
A still further object is the provision of an improved method of producing containers of the 25 type described and a means for erecting the same 'Fig. 1 is'a side view, partly broken away, of a a container and rim member constructed in accordance with the invention; a
Fig. 2 is a sectional view taken through the center of the container and showing an initial stage in the mounting of the rini member on 40 the body portion of the container;
Fig. 3 is' a fragmentary view similar to Fig. 2 and shows a second stage in the mounting of the rim on the container; and
Fig. 4 is a view similar to Fig. 3 showing a 5'final stage inthe mounting of the improved member on the container body portion.
Within recent years the practice of packaging ice cream in fibrous containers has been recognized as being highly desirable from many .50 standpoipts. such as economy, convenience and sanitation. Generally, the containers are constructed of flexible'fibrous' body members produced from paper board. To provide added strength for the bottom and top edges'of con- '55 tainers of this type. it has been suggested to employ metallic rim portions of various types, al-
though such rim portions have been satisfactory from many standpoints. Several structural limitations to these rim members and their mode of attachment have made their use objectionable. In accordance with the present invention these objections very' largely are eliminated and there is provideda container and rim member which are easily assembled and when so assembled provide' a construction of great utility.
In the embodiment of the invention shown in the drawing the container Ill composed of a fibrous fiexible body portion of tubular construction is provided with vertically extending score lines ll dividing the body portion into a series of adjacent vertical strips. This type of container is of well known construction and when a commodity such as ice cream is frozen in the container the commodity expands, with the result that the score lines ll assist in maintaining a uniform finished package.
Adjacent the upper edge I2 of the body portion of the container is provided an outer strip l3. This strip may be produced by turning the upper portion of the body member over prior to securing the body portion in tubular form. However, separate strips may be provided for this purpose. The strip l3 preferably is glued to the ,body portion of the container 'along its outer surface so that the strip will be rigidly attached in its proper position. It will be noted that the strip has an upper edge It which is on the same level as the upper edge l2 of the container and that the lower edge I! of the strip forms an outwardly extending flange along a line spaced below Y the top edge of the container.
. The rim member which is employed in connection with the container described is indicated generally at It and preferably is constructed of a metal such as aluminum. The rim member has a vertical wall portion ll of annular construction. The lower end of this wall terminates in an inwardly extending flange or lip portion II. .Adjacent its upper end the rim member is turned inwardly a d downwardly to Provide a I channel member i9.
2 a 2,232,037 l3 and the body portion of the container. This rim member is mounted over the strip member l3 and the upper edge 01' the body portion of ,the container in such a manner that the flange I8 is positioned beneath the strip, l5, thereby preventing upward retraction of the rim mem- .ber from its position on the container, and the in the manner described. That is, the rim mem-., ber is preformed and the body portion of the container and rim member are assembled by the user when it is desired to set up the container.
,.This assembling does not include crimping or inside diameter or. the lip member ll.
.bers are forming the metal in such a manner as to make it pinch or clamp the material of the body portion.
In mounting the rim member about the container, the upper edge of the body portion ofthe container is flexed inwardly a distance sufllcient for the strip It to pus within the flange It. The container then is moved vertically with respect to the rim member and the upper edge of the c ntainer againis flexed outwardly after it is pas the inner edge of flange It. Upon the .continued vertical movement of the body portion with respect to the rim member the upward edge of the body portion passes into and is received by the channel I! of the rim member. Upon still further movement of the container with respect to the rim member, the flange ll passes belowthe lovger edge I! of the strip "II and the upper edge of the container and the strip l3 snap outwardly to assume the position shown inFlg. 4. Y
Toassistinassemblingtheriman'dbody member there preferably is provided an annular funnel-shaped flange Zll having its narrow edge of the diameter substantially the same as the The member 20 flares outwardly from this position so that the body portion of the container and the strip I 3 easily may be. received therewithin. As the container is pressed upwardly into the member 20 the strip I 3 contacts the inclined funnelshaped walls thereof and the upper portion of the container is flexed inwardly a suiiicient distance for the strip II to pass within the flange I 8. In Fig. 2 the movement haspr so that about one-half of the strip II is withinthe flange member I 8. A second and reversely flared flange 2| has an upper edge of substantially the same diameter as the inside diameter or the channel member I! and is flared inward y and downwardly therefrom. As the upper edge of the container passes within flange I I it strikes the inclined walls of the member II and is deflected outwardly. The upper edge of the member 20 is fltted adjacent the flange I8 and the upper. edge of the member isfltted adjacent the lower edge of the channel member is, as shown in Fig. 2'. It will be understood that these memarried on suitable frame structures not shown a that the rim member 2| will be held in theposition shown in Fig. 2 until the strip It has been received within the rim member. Any suitable means for withdrawing the container from members an and 2| after the rim is mounted therein may be employed. As shown in Fig. 4, 4
the engagement of the rim member with the upper edge of the body portion of the container and the strip I l is complete and the container is being removed from the assembly elements 20 and 2| by continuing the movement of the container upwardly, it being understood that in this method the rim member is mounted in the man- .ner described prior to provision of a bottom.
The construction of the container includes the formation of a flexible flbrous body portion in any suitable manner and the provision of a double edge about the upper edge of the container.
In the embodiment of the invention shown in the drawing, the rim member is mounted thereabout as described and thereafter'any suitable bottom construction may be provided.
the lower edge I! prevents movement of the strip vertically with respect to the container. Channel member I! extends downwardly a distance suiiicient to prevent the body portion from being flexed inwardly. In this manner the flange II is maintained in engagement beneath the edge It. After assembling the rim member I to the upper edge of the container, the container may be employed in the usual manner and after filling with ice cream or some other commodity a conventional cover 22 may be placed over, the top of the container in the usual manner.-
Many changes may be made in the structure described herein for purposes of illustration and explanation without departing from the scope of. the'invention and such changes are intended to be included in the appended claim.
Iclaim: v The method of forming a container, which comprises forming a body portion of'flexible flbrous material, providing a'paperboard strip adjacent the upper edge of the body portion, forming a metallic rim member having an inwardly extending lip portion along its. lower edge of smaller diameter than the diameter outside of said strip and having an upper channel member formed by an inwardly and downwardly turned lip portion for receiving said strip and the upper edge of said body portion, flexing said upper edge inwardly and moving the same past the lower lip portion of said rim member, expending said upper edge suflicientiy to enter said channel portion upon further movement and be--' fore the lower edge of said strip passes, said lower lip, and moving said body portionfurther with respect to said rim to cause said lower lip to pass beneath the .lower edge of said strip' while the upper edges of said body portion and strip are within said channel member.
