Description

Patented Jan. 2, 1934 CARTON Leo Kulpinski, Wausan, Wis.,- assignor to The 1 Menasha Products Company, Menasha, Win,
a corporation of Wisconsin Application November 30, 1982 Serial No. 644,929
'12 Claims. (01. 229-16) This invention relates to cartons intended particularly as containers for 'icecream or other food products, although the features of the presout invention may be applied to cartons intended for various purposes and variously constructed.
The present invention is intended to insure the provision of a base, the marginal portions of which will lie in an even plane, and the center portion of which will be slightly elevated so that the carton will rest or stand on its margin, which insures a firm and'even support, which is of particular advantage in the case of cartons intended to be filled with ice cream or the like from an automatic fiIIing machine.
In filling operations of this character, it is quite important that the carton stand firmly on its base, and previous experience with similar cartons which lacked the bottom features prestion with the accompanying drawing, wherein,-
Figure 1 is a perspective view of a carton embodying the bottom features of the present invention;
Fig. 2 is a bottom view of the same.
Fig. 3 is a developed view showing the completed carton opened up or laid out to indicate the form of the blank and position of the folding lines;
Fig. 4 is an enlarged sectional view of the base takenon line 4-4 of Fig. 2; and
Fig. 5 is a similar view taken on line 5-5 of Fig.2.
For purposes of illustration. a carton will be described which is formed from a blank which includes side walls 10-10, which are of generally rectangular formation but slightly divergent from the inner edge outwardly; inner end walls 1l-11, outer end walls 12-12; afrectangular base 'or bottom 13, which in the blank occupies the space between the side walls 10-10; and the triangular tongues 14-14 which extend outwardly from the ends of the base and are out free fromthe ad-' jacent-outer end walls 12-12 along slits 15.
The blank thus formed is folded into a carton by bending the side walls 10-10 upwardly along folding. lines 16-16, after which the ,inner end ,walls1*11-11 are folded inwardly along folding lines 17-17. The tongues 14-14 are next folded upwardly along folding lines 18-18 to liead- Elacent the inner end walls 11-11, after which the outer end walls 12-12 arefolded along folding lines 19-19 to register with the inner end walls 11-11, which brings the tongues 14-14 into interposed relation between the inner and outer end walls.
The carton thus folded is held by gluing applied to the opposed faces of the inner and outer end walls, which results in a carton having side walls and a bottom of single thickness, and end walls of double thickness throughout, and of triple thickness throughout the lower portion of the ends of the carton. This formation also-results in a base or bottom which is defined around its entire margin by folding lines, so that no raw edges are exposed along the edge of the base.
The carton thus constructed, and without the special features presently to be described, provides a base which is seldom plane or flat, by reason of thefact that the bending up of the side and end walls has a tendency to slightly bulgethe base downwardly, so that it presents a somewhat rounded or outwardly bulged surface which fails to afford the firm contact required in the handling of the cartons by automatic filling machines, and the present invention is designed to improve the base formation so that a firm plane marginal contact is afforded. This result is secured by embossing the base in such a way as to afford a rectangular elevated center panel 20 surrounded by a relatively narrow margin 21,- the ends and side of which are separated by diagonal scoring lines 22 extending from the corners of the rectangular center panel to the outer corners of the base.
The material of which the carton is composedpreferably paper board or the. like-is distorted or displaced by the embossing operation, so that along the lines of juncture between the panel and the margimthe material is displaced in the form of an abruptshoulder or offset 23 and affords a margin which preferably extends in oblique relation from the shoulder 23 to the marginal outer bending or folding lines for the side and end walls of the carton. This gives to the marginal folding lines a slightlyacute angular formation, and this, in conjunction with the diagonal scoring lines 22 in the comers, serves to stretch or deform the paper stock of the base sufficiently to permanently hold the center panel in'elevated relation and afford a marginal base support in a uniform plane, so that the folded margin will possess not only an accurately formed base but one which affords added stiffness to the carton as a whole, by
his I The provision of the diagonal corner scoring further assists in permanently deforming the material to the extent necessary to insure rigidity and prevent bulging, and at the same time the elevated bottom, which stands out of contact with any supporting surface save at the edges, affords better insulation against the melting of ice cream or the like, by reducing the area of contact with the table or other surface upon which the package is deposited.
