The present invention relates to containers, and more particularly to collapsible, folding cartons adapted to be set up to retain individual articles, such as bottles.
One object of the present invention is to provide a folding carton of relatively simple form which is easy to set up and which, while affording adequate protection for a bottle or other article, at the same time is of such a shape as to conform to the shape of the article contained therein as well as to receive and cooperate with various forms of decorative printed matter that it may be desired to apply to the surface of the carton.
A further object of the invention is to provide 5 a carton adapted to hold a single article, such as a bottle, the carton being shaped to simulate the general outline of a conventional Christmas tree and base therefor.
A further object of the invention is to provide securing flaps for the base of the carton which will adequately support an article therein and will not become readily disengaged.
To these and other ends the invention resides in certain improvements and combinations of 5 parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.
In the drawings:
Fig. 1 is a perspective view of a preferred embodiment of a container made in accordance with the present invention;
Fig. 2 is a view of the container blank in tubular, collapsed condition;
Fig. 3 is a bottom view with bottom flaps partially assembled; and
Fig. 4 is a view of the blank spread out.
Similar reference characters throughout the several views indicate the same parts.
The present invention as disclosed provides a multi-sided collapsible carton having two main panels thereof tapered to a peak with two cooperating side panels of rectangular form joining the upwardly tapered edges of the main panels. Additional side wall .portions near the bottom of the container are inclined downwardly to a ilat base or bottom wall whereby the carton is adapted to generally simulate a tree, house, or similarly shaped object.
Referring more particularly to the drawings,
the blank of the carton comprises wall sections 5 and 8 of pentagonal shape (hereinafter for convenience sometimes termed front wall 5 and rear wall 6) a side wall section 1 disposed between the front and rear wall sections, and a side wall section 8 integrally `joined to the side of the front (c1. zza-z2) and 6c, 6d which converge downwardly but ter- 10 minate short of meeting so as to provide a relatively broad base line, indicated at 5e and 6e. It will thus be noted that the upper portions of the front and rear walls are triangular and the lower portions are trapeziform in shape. 15
The rear wall 6 is provided with a flap 9 which extends along the edge of the triangular portion of the rear wall which is opposite to side wall 1.
For the purpose of retaining the carton in closed condition along the side wall portions 8 and 9, 2o retaining means are provided which, according to the present invention, are constituted by tabs I0, l0, on the side wall portion 8, and slits II, Il formed along the score line 6a separating the rear wall 6 from the ldap 9.
In order to completely close the upper edge of the carton a flap extension I2 is provided at the upper end of the side wall 1.
The side wall 1 has at its lower end an extension I3 serving as a continuation of the side wall 3G between the bottom and the point at which the front and rear walls start to converge downwardly. A similar wall portion Ill is formed at the other side of the carton. This wall portion is in the form of a flap extension on the inclined ylower edge of the rear wall 6; The wall portion I4 preferably carries on its upper edge a flap I5 to underlie the wall 8 and form a closed joint between the wall 8 and the wall M.
For the purpose of enabling the container to be made up in tubular form, a glue ap I6 is provided on the wall l 4 whereby the latter may be hingedly secured to the front wall 5 along the line 5c. It is to be noted that lines 5c, 6c, 5b and 6b are in parallellism and that opposite sides are equal in 45 width, whereby the carton, in tubular form, is adapted to be collapsible to a flattened position. The 'bottom of the carton is preferably formed by flaps I1 and I8 located respectively on the front wall 5 and the rear wall 6. The iiap I1 5o has a tuck-in flapextension i9 thereon adapted to lie against the inner face of the rear wall 6 when the box is set up. The 4flap I8 carries a locking tab 20 comprising a central portion 2| I with wing portions 22, 22 defined from the central 55 portion by means of the score lines indicated. The locking tab is adapted to be inserted into the s1it23 formed along the score line 5e at the base of the front Wall 5. In order to insert the locking tab 2li the wing portions 22 will be folded against the central portion 2| until the tab is completely inserted after which the wing portions 22 will tend to regain their original position which causes the effective width of the tab to be greater than the length of the slit 23 thus preventing removal of the locking tab except by either tearing the slit or the locking tab.
In order to retain the side Wall portion I3 in proper relation with respect to the adjacent lower edges of the front and rear walls the portions is and 41 are each provided with a flap extension thereon indicated respectively at 243 and 25. These extensions are provided with cooperating engaging portions 2@ and 2li.
For the purpose of closing the joint between the side edges of side wall portion i3 and the edges of front and rear walls 53 and suitable naps 2B and 29 are provided, located respectively on front wall 5 and rear wall 5 and joined thereto along lines 5d and 6d respectively.
The blank of the container, shown in Fig. 4, after being cut and scored as illustrated, is secured in tubular form, see Fig. 2. The. cartons in this condition are shipped to the user to be set up by a eW simple operations which in general will comprise folding inwardly the naps 28 and 29 and folding the side wall portions thereover after which the cooperating flaps 24 and 25 are secured together. The flap extension H is then brought in position at the bottom and the tuck-in flap B9 is inserted between the inner face of the rear wall 6 and the interlocked flaps 24 and 25. The flap i8 is then folded over against the ilap I'l and the locking tab 20 is inserted through the slit 23 as above described.
The next operation is to close the upper part of the side wall formed by portions 8 and 9. First, the iiaps I2 and l5 are bent over into the positions shown in Eig. 1; the ap 9is then folded over against the flaps l2 and l5 after which the side wall portion 8 is folded against the flap 9 and the tongues Hl. Ill are inserted into the slits il, H.
The use of the terms front wall and rear wall herein is not to be understood as limiting the description thereto but is for simplicity of designation. It is within the scope of the present invention to interchange these walls so that the rear wall becomes the front wall and, vice versa.
The article to be packed in the carton can be inserted through the opening that is closedby the iiaps 8, 9, l2 and l5.
From the foregoing it is apparent that the carton of the present invention can be utilized in substantially the same manner as a tubular carton of regular form and can be readily sealed Without the use of adhesive or other securing means and without requiring the use of any machinery. The cartoncan be formed in a pleasing and artistic shape whereby it is adapted to receive decorative printing representing various forms, such for example, as a conventional form of Christmas tree.
While the present description sets forth a preferred embodiment of the invention, numerous changes may be made in theconstruction without departing from the spirit of the invention, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
