Claims.

The invention relates to paper or fiber containers particularly designed as a single service container for holding milk or other liquids, and is susceptible also of holding granular or other 5 commodities of a non-fluid nature. The inven tion relates to the class of containers fully disclosed in my issued Patents No. 2,089,958, granted August 17, 1937, and No. 2,085,979, granted July 6, 1937, for Containers. The present invention has for its objects to.provide certain 'new and useful advantages over such a container to which my said patents aredirected.

A principal object of theinvention is to provide a paper or fiber container of the character described, the body. and one end wall of which is of two-part construction, said parts being capable of convenient folding and telescoping together to comprise a completed tubular and preferably non-circular body including as a part thereof a strong end wall of double thickness.

A further object of the'invention is to provide a container of the character described which may be constructed of web or sheet material of much smaller dimensions than in the instance of the container body contemplated in my aforesaid issued patents. A feature of the instant invention resides in the fact that the two-part container body is strongly reenforced at its ends and at its side or corner edges, thereby rendering the same highly resistant to the shock and strains of use in the packaging and dispensing of liquid contents, such as milk or the like.

A still further object of the invention is to provide a paper or fiber container having a closure member hingedly secured to an end wall thereof, the features of construction being such as to permit said end closure member to be se- I cured to the desired end wall adjacent the filling and dispensing opening while one of the blanks of the two-part bodyvis in the flat and prior to folding and assembling, or said closure member a may be attached to the container after the 'two- 7 .part body has been assembled and adhesively or otherwise secured together, and prior to attaching thereto a separate and memberat the opposite open end of the receptacle.

When the closure member .is secured to an end wall of the partially assembled receptacle, the manner of securement provides an added reenforcement to hold the end' wall of double thickness closely together thereby cooperating with the'usual adhesive in maintaining the conformation andrigidity of the completed package.

Numerous other objects and advantages of the invention will be apparent as it is better underreference to Figs. 1 to 8 inclusive, In indicates generally one of the body blanks and II its comstood from the following description, which, when.

taken in connection 'with the accompanying drawings, discloses a I preferred embodiment thereof.

In said drawings, 1 Fig. 1 is a plan view partiallybroken away of one of the fiber or paper blanks of which the container body is constructed, said view indicating in dotted lines the manner of folding the blank. V

Fig. 2 is'a similar view of the remaining blank which enters into the construction of the container body." I

Fig.3 is a perspective view showing the manher of assembling or telescoping the blank parts of Figs. 1 and 2 after the blanks have been fold- 'ed as indicated in said flguresi parts being broken away.

Fig. 4' is a similar view showing the completed container with the bottom wall secured inp0s1- 20 tion and a. closure member'attached to the opline. ii -6 showing the completed container in accordance 'with the assembly of Fig. 7.

Fig. 9 is a plan view similar to Fig. 1, showing a. slightly modified construction of the corresponding body blank. I

Fig. 10 is a perspective view similar to, Figs. 3 and 7 and showing the two body blank members in partially assembled or telescoped relation.

Fig. 11 is a perspective view similarto Figs. 4 and 8, and showing the completed container assembled as indicated in Figs. 9 and 10.

Referring to the drawings, and withparticular panion body blank. The blank member III is cut away as shown at. a to constitute opposite side wall members 12, 13.. and an integral end or top wall portion l4. Afilling and dispensing opening indicated at 15 is provided in the'top wall member. The blank 19 is further scored or creased along folding lines 16 to provide side wall enclosing flanges ll at the side edges of the body-wall members 12 and I3, respectively.

' Said opposite side wall portions I 2, I3, are formed by folding the flat blank along score or crease lines I3, defining the opposite edges of the top wall. Depending opposite flange portions l9 are provided in the top wall M by folding the blank along the oppositely disposed score lines provided in the top wall, it being understood that the flange portions l1 and I9 are folded so as to extend in the same direction or inwardly of the body blank to produce an integral'U-shaped wall portion best seen in Fig. 7.

The companion body blank H is similar in material respects to the body blank it, the same being folded along spaced score or crease lines 2| to provide oppositely disposed spaced side wall portions 22 and 23, and an intermediate top .o1-.--

end wall portion 24. A filling and dispensing opening indicated at isprovided in the top wall and is disposed to register with the opening {5 when the blanks are in the partially assembled position as shown in Fig. 3.

In assembling the two-part bodyto form the l finished container illustrated in Fig. 4, the blank members It and I l folded as described, are turned at right angles and the-body blank member H is inserted or telescoped over the blank member II as shown in Fig. 3, ,with the flange portions IT and I! of the inner blank member I'll engaging the opposite margins of the opposite side wall members 22 and 2.3 of the outer folded blankmember ll. Suitable adhesive, preferably a heat.

sealing thermo-plastic adhesive, is or may be provided on the outer surfaces of the flanged portionsll of the blank member land which serves to seal the engaged parts securely in position. The top end wall of the assembled container "body is of double thickness consisting of the wall portions I4 and 24 having the registering and filling apertures l5 and 25 therein.

If desired, the assembly may be made by reversely telescoping the blanks as shown in Fig. 1 wherein thefiange portionsll of the blank member. I II are disposed outwardly of the nonflanged innerblank member H instead of inwardly thereof as shown in Figs. 3 and 4. In. such instance the inner surfaces of the inwardly turned flanged portions llv of the blank member III are preferably provided with a suitable ther-r mo-plastic adhesive so as to secure said flange portions to the adjacent wall portions22 of the formed by the registering apertures I5, 25. Said closure element further includes an outwardly projecting finger engaging tab portion 29 to enable the plug to be released from the closure when desired for the purpose of filling the contamer or for dispensing its contents. The staple -2'| permitsthe closure member to be hinged upwardly and downwardly thereon for reclosing the container without displacement of the closure relative to the aperture, thereby constituting the closure a permanent part of the cont-ainer body. When in closed position the inner wall portions of the cup shaped section 23 may be expanded outwardly to engage beneath the top wall of the container to serve as a mechanical lock insuring the outer telescoped member as shown in Figs.

against inadvertent displacement of the closure relative to the filling opening. a

.top wall 2% of the blank member ll while said members are in the flat and prior to folding, telescoping and assembling, depending upon which body blank member 10 or II constitutes 4 and 8 respectively. 1

After the U-shaped body blank members l0 and H are completely telescoped together, the bottom or open end of the container is subjected to die pressure to reenforce such end and secure a bottom closure member thereto; Under such die action the lower side wall portions l2, I3; 22 and 23 are inclined o r bent inwardly as at 30 (Fig. 6) and thence outwardly as at 3| to constitute a shoulder or ledge providing an abuts ment for an imperforate end closure member 32 conforming to the configuration of the said end walls. After the closure member 32 is inserted in position the lower wall portions are bent inwardly thereover as indicated at'33 to securely lock the same in position. A suitable thermoplastic adhesive is preferably provided at this area to securely seal the end closure member 32 in place between the portions 3| and 33 of the container body wall. In'this manner a secure reenforced end construction is provided for the two-part body wall oppositeto the substantially integral end portion having the filling and dispensing opening and closure element 26.

The completed container may be .rendered moisture and liquid proof, as well as completely sterile, by coating the inner and outer walls thereof with a suitable wax like material such as paramm-such coating being-'preferablyprovided by passing the completed container through a bath of melted parafin or the like while the closure element 26 is in open position. Surplus paraffin is drained from the container as it leaves the. bath,.after which the closure member 26 is inserted in the filling and dispensing opening and removably sealed in place by pressure and the adhesive qualities of the paraflin as the same becomes cooled or chilled after the container leaves the bath.

In the slightly modified embodiment of Figs.

9 to 11, inclusive, the body blank member II is similar tothe body blank In of the hereinabove to closely register the end wall members 24, "a

and apertures 25, I511 with one another. After assembly the side flange portions Ha of the as by heat sealing the previously applied thermoplastic glue to the adjacent surfaces of the side wall portions 22 of the inner blank H.

The open end of the assembled container is provided with an end closure member similar to the closure member 32, and is subjected to the same die pressing action, and the end 010- sure member is adhesively secured in place as in the instance of the heretofore described embodiment of Figs. 1 to 8, inclusive. The closure member 26 is also secured in place to the top wall of the container as in the instance of the first mentioned embodiment, either by stapling the same to the blank member ll adjacent the filling and closing opening while said blank is in the flat, or by stapling the same to both end wall portions 24 and Ma.- of the completely assembled blanks prior to inserting and securing the bottom end closure member 32 in position. The completed container as in the instance or" the first mentioned embodiment may then be subjected to a melted paraflin or other suitable bath of wax-like material so as to coat the inner and outer walls thereof and render the same moisture and liquid proof as well as completely sterile and in readiness for filling and dispensing purposes.

In the event the contents are of solid or granular material the invention contemplates if desired filling the container after the two-p'art body has been assembled and secured together and prior to the application of the end closure member thereto.

.The advantages and nature of the reenforced end of the container having the closure element 32 secured therewithin, are more fully pointed out in my prior patents hereinabove referred to.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
