4 Claims.

This invention relates to folding cartons for packaging granular materials and, more particularly, the invention relates to the provision of an improved form of pouring spout therefor.

It is one of the objects of the invention to provide a type of pouring carton that will be comparatively inexpensive to manufacture and having a spout that will be of substantial construction, convenient to operate, readily accessible, and which will not interfere with the sealing of the ends of the carton on the various types of automatic sealing machines that are now in use.

A further object of the invention is to provide a pouring cart-on that will be attractive in appearance and substantially leak-proof. v

A further object of the invention is to provide a pouring carton that will be 'adapted to be enclosed in a so-called tight-wrapper without lessening the accessibility of the pouring spout or without sacrificing any of the desirable characteristics of the spout. I

Other objects of the invention and the features of novelty will be apparent from the following'description taken in connection with the accompanying drawing, of which Figure l is a perspective view of the end portion of a carton embodying my invention, with the sealing fiapsshown in open position;

Fig. 2 is an enlarged detail section on the line 2--2 of Fig. 1 and showing themanner of applying the spout to one of the flaps;

Fig. 3'is a view similar to Fig. 2 but showing the spout in open position;

Fig. 4 is a perspective view of the fiap which carries the spout and the spout detached therefrom but in such relation thereto as to indicate the manner in which the spout is applied;

Fig. 5 is an end view of the sealed carton with the wrapper thereon;

Fig. 6 is a detail section on the line 66'of Fig. 5;

Fig. 7 is a perspective view of the end of the carton. with the spout in the open position, and illustrating the manner in which. the spout is used; and

Fig. 8 is a plan view of the. wrapper before being applied to the carton.

Referring to the drawing, I0 indicates the body of a common form of rectangular folding carton which is provided with the flap extensions II, I2, I3 and I4 thatare adapted to be foldedinto overlapping relation and glued together to form the end wall of the carton. The flaps I2 and I4 are the inner flaps and. in sealing the end of'the carton, these flaps are first folded in so as to lie in the same plane. The intermediate flap I3 is then folded over the flaps I2 and I4 and glued thereto, and the outer flap II is then folded over the flap I3 and glued thereto. v

As will. be seen from Fig. 4, the inner flap I4 is provided with an opening I5 from which the pair of cuts I6 and I1 extend toward the foldline or hinge I8, which constitutes the line of attachment of the flap to the'body IQ of the carton. Another pair of cuts I9 and extend from the opening I5 toward the free end 2I of the flap I4. The cuts I6 and Il form a tongue 22 and the cuts I9 and 20 form a tongue 23, these tongues being in opposed relation on opposite sides of the opening I5. A small cut 24 is provided at the base of the tongue 22,- for a purpose which will be later described.

A spout member indicated, generally, by the letter A is formed of sheet metal, such as aluminum, or of any other suitable material and comprises a pair of side walls or wings 25 and a connecting wall 26 which forms the bottom of the spout. There is a tang 21 on the wall 26 which is adapted to be inserted through the opening 24 and folded against the inner surface of the tongue 22 to secure the spout member thereto, as shown in Figs. 2 and 3.

The manner of attaching the spout to the flap I I will be clear from Fig. 4 in which the spout is shown as detached from the flap but about to be applied. The wings 25 of the spout member are pressed through the cuts I6, I1, I9 and 20 until the wall 26 engages with the tongues 22 and 23. In thus applying the spout to the flap the tang2'I enters the cut 24 and when the wall- 26 engages the tongues22 and 23 the tang may be folded over, as shown in Figs. 2 and 3. The wings of the spout member have extensions 28 which,

- when the spout is'open, as shown in Fig. 3, en-

gage-the inner surface of the flap I4 and thus limit the opening movement of the spout member.

It will also be observed that the upper edges 29 of the side walls of the spout are curved on a radius which is substantially about the hinge line" of the tongue 22.

The flap I3 is provided with an opening 29 I which leaves the spout member exposed when the flap I3 is folded over and sealed against the flaps I2 and I4. The flap II has a line of perforations 30 which define a tear-out section 30' that is adapted to register with the opening 29 when the flap I I is folded over and sealed to the flap I3.

Referring to Fig. 8, it will be seen that the wrapper is provided with the substantially rectangular notches 3| and 32 as the portions there-' rectangular opening 34 when the end portion of the wrapper is folded and sealed, as shown in Fig. '7. v

In using my improved pouring carton the end thereof, which contains the pouring spout, is first sealed in the sealing machine and the carton is then filled and the four flaps at the opposite end of the cartonare then folded in and sealed in the regular manner. The filled and sealed carton is then transferred to the wrapping machine and the wrapper applied thereto in the well-known manner. While the spout member A, when in its closed position, substantially seals the opening I5 in the flap I4 and prevents leakage of the contents, the package, as a whole, is rendered leak-proof by the use of the wrapper thereon. When it is desiredto open the carton or remove any of the contents thereof, an opening is made at the point 35 by cutting the wrapper opposite the opening 29 by means of ones fingernail or a knife and the tearout section 30 is then removed so as to expose the wall 26 of the spout member. By the insertion of ones fingernail or a knife under the end 36 of the spout member, the latter may be swung to the open position as shown in Figs. 3 and 7. From Figs. 3 and 4 it will be noted that the tongue 23 is positioned between the side walls 25 of the spout and acts as a reinforcing spacer for these side walls when the spout is in the open position. Since the walls 25 of the spout member are thus supported and guided in the cuts l9 and 20, the spout has a very substantial and durable connection between the tongue 22 and the flap is relieved of much of the stress that it would be otherwise subjected to in opening and closing the spout. After the package has been opened the spout may be readily opened and closed at will and, when in its closed position, it thoroughly seals the opening l5 so that the contents of the carton will be protected from contamination by foreign matter.

While I have illustrated anddescribed what I now consider to be the preferred form of my invention, it will be understood that changes may be made in the details of theembodiment thereof which I have'illustrated and described, without departing from the spirit of the. invention as defined in the appended claims.

Having thus described my invention, I claim:
