Patented Dec. 19, 1933 UNITED STATES PATENT OFFICE SPOUT EQUIPPED BOX Application December 14, 1931 Serial No. 580,746

12 Claims.

My invention relates to containers and more particularly to a folding paper board box adapted to contain dry products that can be poured therefrom, and, it is a distinct and practical improvement designed to overcome certain practical objections to, and defects in, containers having integral pouring spouts.

The primary object of my invention is to improve the spout construction of a folding box container wherein the spout structure is an integral part of the paper board material of the box, and, thereby provide a box of the pouring spout type which possesses advantages in points of simplicity and efiiciency, and, at the same time proves itself comparatively inexpensive in cost of manufacture.

A further object of the invention resides in the provision of a box from a blank wherein the pouring spout proper is formed entirely from one of the flaps, or extensions of one of the walls of the box, thus not requiring more than the material of the flap for the formation of the spout.

With the above and other objects in view, the

26 inventionconsists in the novel features of construction, arrangement and combination of parts hereinafter more fully described and finally pointed out in the claims hereto appended.

Referring to the accompanying drawings I forming a part of this specification, wherein like characters of reference denote similar parts throughout the several views:

Fig. 1 is a view of the, blank as it is cut and scored preparatory to folding same into box formation.

Fig. 2 is a side view of the spout corner of the box just prior to folding the spout wings into parallel position.

Fig. 3 is a sectional view of one corner of the box showing the spout wings folded into parallel position. Fig. 4 is a sectional view of one corner of the box showing the spout carrying flap folded into position and the spout in its closed position.

Fig. 5 is a topplan view of one corner of the box showing the spout closed.

Fig. 6 is asimilar view showing the spout op n- Fig. 7 is a view of one comer of the box showing the spout in side elevation and in its open position.

' The box, container, orcarton is formed from a suitable paper, or paste board blank, and such 5 blank is designated generally as A, and clearly illustrated in Fig. 1 of the drawing from the inside face thereof.

The blank A is shown as having, or comprising the several box wall sections designated 1, 2, 3, 4 and 5, and the flap sections designated 6, 7,

8, 9, 10, 11, 12 and 13 and a final section designated generally as B, which latter section represents the material from which the pouring spout is formed. All the flap sections are severed from each other, as is customary in the art of paper folding boxes of the class herein described.

The section B is partly severed froni the extension 11 by inclined slits '14 and 15 which slits extend from the side edges of section 12 and section B and inclined toward the inner ends of.the score lines designated 16 and 17, respectively, running longitudinally of the spout section B, in spaced parallel relation, to divide the spout section B into an intermediate, or floor section 18, and two like wing sections each designated 19. The two wing sections have their free edges curved, as at 20, and the corners of the wing sections adjacent the side edges of section 12 are cornered, as at 21 to provide corner wing extensions 22 adapted to act as stops for engagement with the inner faceof section 13, as will be more clearly apparent hereinafter. The free end of the floor section 18 of the spout is extended beyond the curved edges of the wings 19 to actas a finger grip 23 for opening the spout and the, edge thereof is preferably curved, as at 24. p

The finger grip extension 23 is adapted to engage the upper face of section 13 when the spout is closed to limit its closing movement thereof, as will be more clearly apparent hereinafter.

Section 13 of the blank is provided at its inner end with a centralized rectangular cut out portion, or recess 25 to serve in the capacity'of an outlet opening for the discharge of contents from the box, and, it is adapted to be closed by means of the spout, when the spout is in its closed position and to be opened by swinging movement of the spout from its closed into its open or pouring position.

Section 11 of the blank is provided at its inner edge portion with a suitable cut out portion or recess 26 to permit of the passage of the wings of the spout into the box through flap section 11 when moving the spout into its closed position from its open position. Recess 26 of section 11 is. preferably cut back slightly farther than recess 25 of section 13, so as to allow the spout wing stops 22 to engage the inner face of section 13 when the spout is in open position, although this is not necessarily required as the stops 22 can, if desired, engage the inner face of section 11 of the blank when the blank has been folded into box shape formation.

In forming the blank into box formation, sections 1, 2,-3, 4 and 5 are folded along the score lines 2'7, 28, 29 and 30 to form a rectangular body structure, and section 1 overlaps, preferably on the outside of section 5 and it is adhesively secured thereto. Sections 6 and 8 are then folded inwardly on the score lines 31 and 32, and then section 9 is folded on score line 33 to lap over sections 6 and 8, and finally section 7 is folded on score line 34 to overlap section 9 and it is adhesively secured thereto. Thus, the side walls and the bottom of the box are formed in the usual manner of folding paper box construction withfour thicknesses of paste board forming the bottom of the box.

Section 10 is then next folded inwardly on score line 35. Following, section 11 is folded on score line 36 to overlap section 10, and then section 13 is folded on score line 37 to overlap section 11, and it is adhesively secured thereto.

Next, the two wing sections 19 are folded toward each other on the score lines 16 and 17 so as to lie parallel with each other, and finally, the short flap section 12 is folded on score line 38 to rest on the recessed end of section 13 and it is adhesively secured thereto. In order to permit section 12 to overlap the recessed end of section 13, the score line 38 is formed out of alignment with score lines 36 and 37, so as to allow for folding of section 12 over flap section 13, which itself overlaps section 11. When the box has been thus formed, it will be observed that section 12 and fioor section 18 of the spout lie in a plane with each other and with the finger grip 23 resting on the upper face of section 13 adjacent the inner end of recess 25. Thus, it will be observed, the top of the box is formed in the usual manner with the exception that the short flap section 12 overlaps the outer section 13 instead of being overlapped by sections 11 and 13, as is usual in folding paper box construction.

During thefolding over of section 13, it will be observed that the wing sections 19 are to be directed into the opening formed by the recess 25, in section 13, and the spout is then in its closed position with the finger grip engaging the upper face of section 13 adjacent the inner end of recess 25 to limit further inward movement of the spout relative to the opening formed by the recess 25.

To open the spout, the floor 18 thereof is pulled upwardly and back on the score line 39 by grasping the finger grip 23, and 'when it is swung to a full open position, the stops 21 will engage the inner face of section 13 adjacent the inner end of the filling and discharge opening formed by the recess 25. The recess 25 does not necessarily have to be used as a filling opening, but can be so used, if desired.

From the foregoing description, it is evident that I provide a pouring spout for boxes, which is formed integral with, or articulated from the material of one of the top flaps, which isthe same width as the flap when the wings of the spout are flattened out and wherein'the wings of the spout are readily foldable for insertion into the discharge opening of the boxfor closing the same, and wherein the spout can be readily swung to an open position to permit pouring of contents from the box. I

The many advantages of the herein described invention will readily suggest. themselves to those skilled in the art to which it appertains.

From the foregoing description, it is evident that a simple device for this purpose has been disclosed, but it is to be understood that I.do not desire to restrict, or limit myself to the very details of the construction shown and described,

which is merely illustrative, it being obvious that changes, not involving the exercise of invention, may be made without conflicting or departing from the spirit of the invention within the scope of the appended claims.
