5 Claims.

This invention is a dispensing container, forming a packing receptacle for various commodities in liquid, powder, granular or flake form, such as milk, syrups, salt, sugar, powdered soaps and other pourable products, and is designed to overcome the defects and high cost of dispensing devices now in use, and which consist of individual spouts or closures which are separately formed from the container and attached thereto. The pouring spouts or lips now in use are usually formed of metal, and in some cases of cardboard, and are not formed from a portion of the container or the cover therefor.

These spouts usually leak about their mounting slots, and when they are made of metal, add considerably to the cost of manufacture of the containers when considered in the light of the enormous volume of such containers produced.

This invention contemplates the forming of the spout or dispensing aperture from a portion of the container and is maintained integral therewith, and the material of the container with the spout or closure portion forms its own hinge, while a sealing disc or diaphragm which is merely pasted over the closure or spout portion to seal the same for shipment, reinforces, and makes responsive, the hinge portion, and forms auxiliary sealing means when the seal has been broken by contact of the edges of rupture.

This diaphragm is preferably formed of a thin paraffine paper resilient in nature or an elastic or resilient material, such as rubber, rubberized paper or fabric, or tough paper such as the usual kraft papers which are extensively used as wrapping paper and in the manufacture of bags, since this paper is tough, resistant to bending and resilient, and which in connection with the cardboard from which cartons are usually made (and which has little inherent resiliency) normally maintains the closure in closed position.

Agar-agar forms a very suitable paste for the diaphragms for fiuid containers since it is noncontaminating, and agar-agar or parafiine is very desirable for use as pasting means for cartons when paper is used for the diaphragm, or rubber cement may be used provided a non-contaminating solvent for the rubber is employed.

The main object of the invention is to provide a pouring spout for containers which spout is an integral part of the container and made operable at will, and to provide means for hermetically sealing the spout portion for shipment.

Another object of the invention is to provide a container cover with a portion normally held in is to seal the closure portion during. shipment with contents by means of a resilient diaphragm in conjunction with a non-contaminating adhesive for application of the diaphragm.

Other objects and advantages of the invention will become apparent as the following description is read on the drawing forming a part of this specification and in which similar reference characters are used to designate similar parts throughout the several views, of which:

Fig. 1 is a fragmentary perspective View of a container with the invention applied thereto.

Fig. 2 is. a modification of the invention in which the rimof the cover does not form a part of the closure, and shows side releasing means for the closure.

Fig. 3 is a modification of Fig. 2 showing end 5 releasing means.

Fig. 4 is a section taken on line 44 of Fig. 2.

Fig. 5 is a modification of Fig. 2 showing a central releasing slot.

Fig. 6 is a modification of Fig. 1 showing only a portion of the cover rim and also a portion of the top of the container forming an integral reinforcing portion of the closure.

Fig. '7 is a modification of Fig. 1 applied to a rectangular container.

Fig. 8 is a modification of Fig. 2 and Fig. 5 for application to liquid containers.

Fig. 9 is another modification of the invention,

Fig. 10 is a section taken on line llll0 of Fig. 9.

The invention consists of a container body I2 having a cover I3 which is provided with a rim M, which rim is either pasted or otherwise sealed to the body l2, the cover [3 having a closure formed from a portion thereof, the removal of this portion-forming a pouring aperture or spout.

As shown in Fig. 1, the closure I5 is formed by slitting or weakening the cover along two radially converging lines [6 and I1, and about the rim, the portion l8 between the terminals of the slits or lines being left integral with the cover proper and forming a hinge for the closure. These slits, at the time of manufacture, may extend only part way through the thickness of the material, in which case no diaphragm is required. When slit through, a diaphragm l9 of rubber, tough paper or similar material, is pasted over the closure, using a non-contaminating adhesive.

It will be noted that by the combination of an underbody I3 of non-resistant pressboard and a superposed flexure resistant, resilient reinforcement [9, the closure [5 will be normally retained in a closed position and the hinge portion l8 will be efiective throughout the entire time in which such products are usually dis- 7 pensed, while the cardboard of the cover might readily break off in the interim. I

The lip 20 fits within the slot formed in the rim of the cover, fully closing the dispensing opening and providing convenient means for raising the closure.

In Fig. 2, a modification is shown in which the closure 2| does not continue into the rim 14 but terminates at its outer edge 22 substantially parallel with the inner surface of the container cover, so that when closed, the end will rest on the top edge of the container body. An implement receiving slot may be provided in the cover member as shown at 23, or in the closure portion as shown at 24, the assembly being sealed by the diaphragm 25 by means of adhesive 26.

In Fig. 3, another modification is shown in which the radially converging

slits

21 and 28 terminate in a slot 29, while in Fig. 5, the slot 30 is formed centrally of the closure 3|.

In Fig. 6, another modification is shown in which the structure is similar to that shown in Fig. 1 except that the lip includes only a portion 32 of the rim and additionally includes a portion 33 of the upper end of the container body 12, forming a through slot 34 when this portion is slitted out. This forms .a reinforced lip which is convenient to open, the portions 32 and 33 being pasted together and thereby forming a rigid member.

The modification shown in Fig. 7 is identical in all respects to that shown in Fig. 1 except as applied to a rectangular container, the closure 35 having the angular lip 36v which fits over the corner 31 of the body 38, and being formed'fro'm the rectangular cover 39. r l

Another modification is shown in Figs. 9 and 10 in which the cover is slit or weakened along the

lines

40 and 42, which are connected by a slit 4| intermediate their length, and which form the closure members 43 and. 44 as is clearly shown in Fig. 10.

In Fig. 8 is a modification which is especially applicable for use with metal containers such as milk and syrup cans which require both, a pouring aperture and a vent. In this modification, the metal is weakened as indicated by the

dotted lines

45, 46 and 41, permitting a knife or other instrument 48 to penetrate at some point to lift out the weakened portion, which can be readily bent down again for sealing the contents.

As will be noted, the resistance of the composite closure structure permits the weight of the contents, after the seal or diaphragm is broken, to force the closure open for dispensing but immediately closes when the carton is placed in its upright position. It is therefore, automatic in its action, and should there be any tendency to stick, the closure is readily released by a finger.

The

slots

23, 24, 29 and 30 are provided so that any convenient instrument such as a spoon 48, a nailor knife may be used to rupture the diaphragm and lift the closure.

This arrangement of dispensing and closure means is economical from a manufacturing standpoint, since where the boundaries of the closure are merely weakened, only the cost of forming the weakened lines is reckoned, while in such cases where the closures are formed by slitting, the additional cost includes only the cost of the diaphragm and its attachment. This container complete costs no more to manufacture than present containers cost to prepare them for the spouts; therefore, the entire cost of the spouts is saved.

It will be understood that variations in construction and arrangement of parts which are consistent with the appended claims may be resorted to without. detracting from the spirit or scope of the invention or sacrificing any of the advantages thereof.
