InCanada 21, 1934 1 Claim. (01. 229-11 My invention relates to improvements in folding boxes with integral spouts, and has for an object to provide a box blankfrom cardboard, crai'tboard, pasteboard, or the like, with openings therein, cuts 'therethrough, scores thereon and shapes thereof, which is suitable for being folded into a tlghtly-closable receptacle, and which is provided with a spout formed from the spout blank and foldable into spout shape while being extended to its pouring positionto a stop thereon and also being withdrawable to its fiat shape wherewith the receptacle is closed.

Other objects of my improvement will appear as the description proceeds.

I attain these and other obiects of my improvement with the-mechanism illustrated in the accompanying sheet of drawing, whichforms a part of this specification, in which Figure l is a plan view of a box blank from which a box with a m foldable spout may be formed, Fig. 2 is a top plan view of the formed and pasted box, Fig. 3 is a repetition of Fig. 2 with the detachable piece removed, Fig. 4 is the same as Figs. 2 and 3 with the central portions of the outermost two layers of the material of the top folds broken away, Fig. 5 is a side elevation of the box with the spout extended and stopped in pouring position, Fig. 6 is a front elevation of Fig. 5, Fig. 7 is a plan view of the flattened spout piece, from which the rep mainder of the box blank is broken away, showing optional closure stops thereon, and Fig. 8 is a plan view of the end fragmentary portion of the second top fold showing an optional shape of the closing flap.

Similar characters refer to similar parts throughout the several views. Certain parts are broken away to show other parts hidden thereby.

With more particular reference to designated parts:

In the drawing of the box blank shown in Fig. l the solid lines indicate either margins or cuts made entirely through the material, while the dotted lines indicate scores or indentations to determine and localize the places for bending the material when forming the receptacles therefrom.

The box blank is substantially rectangular in exterior outline and consists of the front side I, the rear end 8, the rear side 9, the front end ll,

iii the first bottom fold II, the second bottom fold ii, the third bottom fold IS, the fourth bottom fold l4, the side flap ii, the first top fold ll, the second top fold II, the third top fold it, the fourth top fold l6,-the spout flap 34, 35 and 36 and 5, the closing flap 41. While in Figs. 7 and 8 the optional closed-position stops are at (:34 and all. and the optional closing-flap shape is shown at 4!, s41.

An opening 4| is cut through the fourth top fold I, an opening 45 is cut through the third 5 top fold II, and a deep notch 48 is, cut into the end of the second top fold Ii.

The corners of the box are formed on parallel dotted lines 20, 2|, 22 and 23. The top folds are bent on the dotted line 24 and the bottom folds 10 are bent on the dotted line 2!.

In addition'to the opening in the top fold It is the through cut-42. The ends of the opening 4| and the ends'of the out 42 are joined by the lines of through perforations 43 and 44. 15

The spout flap is partly severed from the top fold I! by the spaced-apart, aligned through cuts 32 and 33 and the intervening space is marked by the dotted line 1736 which is the locus of a hinge score. Centrally in the outer edge of the spout go flap is arcuate notch a the ends of which are connected to the ends of the hinge score bl by the scores on the dotted lines it and 39. The side walls 40 and s40 of the spout have the arcuate edges 34' and 35, respectively, and the stop lugs 31, 31 are attached thereto adjacent the cuts 32 and 33.

From the through bottom cuts 26, 21 and and the through top cuts 29, and 3| narrow pieces of the material have been removed to pro- 30 vide freedom for the folded parts when forming the box.

The box is shaped and glued in the usual manner withthe number one top fold I! on the inside of the top cover, the number two top fold 5 I! on the top thereof, the number three top fold I8 on the top of fold l9, and the number four top fold It on top of the number three fold and on the outside of the top of the box. The

four top folds are glued together except that the 40 center of the detachable piece 48, which lays directly over the opening on flap It, the spout form and the flap 41 are not fastened by glue to the other parts. The side flap I5 is glued to end piece It and the bottom flaps H, l2, l3 and 45 I4 are glued together, forming the bottom of the box.

with the box thus completed and filled, say

with salt, the top thereof appears as in Fig. 2. I When it is desired to remove the first portion or all of the salt from the box, the removable piece 48 is torn away by catching fast to an edge thereof in the opening 4| and tearing oi! the piece on the perforated lines 43 and 44. Then the top of the box appears as shown in Fig. 3.-

To extend and shape the spout, insert the tine of a table fork, say, beneath the top flap M and, while lifting the flap with the tine, insert the same beneath the spout end at the notch 42% and, by lifting upward on the fork tine, extend the spout and form the same by drawing it through the opening 86 in the second top fold id. The extended and shaped spout will appear as in Fig. 5 and-Fig. 6 with the lugs 37,3lbearing on the bottom surface of the second top fold it, whereby the further extension of the spout is prevented and the spout is fully open standing in the deep notch Qt of the second top fold. To withdraw the spout and close the openings in'the box top the spout is pushed downward into the top of the box through the openings 65 and (it when the resilience of the material at the bends will cause the spout flap to'again u a nearly flat shape, closing the said openings. Fig. 4 is used to show the appearance of the box top after the spout is withdrawn thereinto. Here, the central portion of the two outer folds are broken away and the closing flap M is shown to be, not overlying the spout end as in Fig. 3, but rather beneath the spout where it serves to prevent the flattened spout from entering further beneath the box top, and also as a closure from within the cover to prevent the loss of salt through the box top in case the box be inverted. Furthermore, the particular location of the closing flap (ll, as shown in Fig. 4, provides a finger-nail-hold with which the subsequent extending of the spout is facilitated. V

In the optional shape of spout blank, shown in Fig. 7, the closure stop add is formed by a s boss extending laterally from the outer part of the spout side 2343 and the transverse through cut bid; and the closure stop a35 is formed from a small boss extending from the upper part of the spout side 35 laterally and the transverse through out 1735. When the spout is formed by being drawn outward through the opening 46, the said lateral bosses flex inwardly and pass through the opening and then assume again substantially the positions relative to the spout back 36' which they occupied when within'the box. Thus, when the spout is withdrawn the lugs (:34 and ate protrude over the sides of the opening 46 and engage with the box top to prevent the spout from fully entering within the box. In the optional shape of the closing flap i'i shown in Fig. 8, the notch ad! is not deep enough to leave uncovered an opening in the closed box but it provides for more easily inserting the said opening tine.

I claim,-. v

A device of 'the kind described including, a card-board box, three top folds glued together providing the top of the said box, a detachable piece in the topmost of the said three top folds, the two top folds beneath the said detachable piece having openings therein registering therewith, a relatively shorter bottom top fold, a

spout blank integral with the said short box-top PAUL JOHNSON.
