4 Claims. (Cl. 229-7) The present invention consists of a container, preferably made of paper, which may be formed, sterilized and filled, providing a sealed container especially adapted for use in packaging milk and like products, and equipped with a pour opening which is originally uncovered when the contents of the container is to be dispensed.

It is within the contemplation of my invention 7 to provide a container which although sealed after the container is filled, may be opened with facility when the contents of the container is to be dispensed, the pour opening being relatively small and located near the top of the container and of a contour which assurespouring in a co mpact non-diffused stream.

A further object of the invention is to provide a destructible container especially adapted for use in vending. highly perishable commodities, such as milk, the entire container being machine sealed after the commodity has been packaged; provision however, is made to permit a part of the wall of the container to be severed to provide an opening through which the contents of the container may be conveniently and satisfactorily dispensed, the separable portion of the wall bein positively protected from being casually opened,

by a guard tab which latter completely covers the severable portion of the container wall and is secured to the container wall outside of the 20 severable zone, the guard tab likewise serving to disrupt and carry the severable portion of the side wall of the container into aplane away from the container to permit the contents of the container to be freely poured, the guard tab likewise being usable for reinserting the severed portion of the container into the pour opening, the tab extending beyond the walls of the opening.

A still further object of the invention is to provide a container, which although made in any desired shape, preferably has the upper end thereof, in which the severable portion of the wall is formed to provide the pour opening, tapered or sloped to prevent the accumulation of extraneous materials,-such as dirt, or moisture around the sealing tab thereby preventing possible contamination of the contents of the container when the seal is broken and the pour opening formed.

Other objects of the invention will be apparent from the following description of the present preferred forms of the invention, wherein:

Fig. l is a perspective view of a container constructed in accordance with the present invention,

showing the container sealed. Fig. 2 is a fragmentary perspective view of a container with the tab in an open position and exposing the pour opening,

Fig. 3 is a fragmentary vertical sectional view of the container taken on the line 3-3 of Fig. 1,

Fig. 4 is a similar view taken on the line 4-1 5 of Fig. 2,

Fig. 5 is a fragmentary vertical sectional view of a modified form of container wherein the tab is secured to the container by a staple,

Fig. 6 is a detail fragmentary elevational view 10 of a container blank, illustrating one form of pour opening therein,

Fig. 7 is a similar view showing a pour opening. of a different contour, and Fig. 8 is a fragmentary view of the container showing the latter 18 in a dispensing-position.

After much experiment I have found that in packaging perishable commodities, especially commodities which are highly susceptible to contamination, such as milk, it is preferable to 20 employ a package which is not adapted, for reuse and one which is preferably formed,' -sterilized,

'fiiled and sealed without the intervention of human hands, the container being taken from the machine completely sealed. In this type of con- 25 tainer or receptacle, I prefer to provide a selfcontained means for forming the pour opening; which serves the function of sealing and reinforcing the container at the zone where the opening is to be made, the said means likewise serving to re-engage the pour opening after the latter has been originally formed.

In making up a container in accordance with the teaching of the present invention, a blank is employed adjacent one margin of which a zone 35 is incised. The incised zone may be of any desired contour, but I have found that good results are obtained by providing a substantially triangular shaped opening in that the contents of the container may be poured therethrough in a compact non-diffused stream. Also, in accordance with the teaching of the present invention I pref-' erably. superimpose over the incised zone a tab, the tab being either sealed in conjunction with the sealing of the terminal of the container in which the incised zone is formed, or else being secured to the container by extraneous means. After the blank has been formed into a container by sealing the sides and an end thereof, the receptacle is filled and the open or fill end of the latter sealed. When the contents of the container is to be dispensed, the pour opening isfolrmed by operating the tab. Consequently, the pour opening is originally formed in the container at 5:

the time the contents of the latter is to be dispensed.

In carrying out my invention, I have in the drawing, shown a receptacle 8, which may be of any desired contour, the upper end of the receptacle being preferably tapered or sloped, as indicated at 9, to prevent the accumulation of extraneous materials thereon. The upper terminal of the receptacle is sealed in a suitable manner. In this form of invention the upper terminals of the receptacle are pinched together, as indicated at H], and a binding strip ll of metal or the like fixedly secured thereto. As already described herein, a wall of the blank, which is later formed into the receptacle 8, is incised, as indicated at 12, the incision being of substantially triangular shape, the apex of the triangle being open and extending upwardly to approximately the inner end of the binding strip I I. Superimposed on the wall of the receptacle 8 and extending completely across the incised zone I2 is a tab IS, the upper end of which terminates at the upper end of the receptacle and is secured beneath the binding strip H, as indicated to advantage in Figs. 3 and 4.

The tab I3 is sealed, by a suitable cementitious agent to thewall of the receptacle within the confines of the incision I2, the tab being likewise secured to the receptacle wall around said incised zone. It is to be understood that although the wall of the receptacle is incised, as indicated at l2, the receptacle is re-enforced at this point in superimposing the tab I3 thereover, thus the incision is sealed as well as re-enforced in addition to pro-' viding means by which the receptacle wall, within the incised area l2, may be displaced and the pour opening formed from a hitherto sealed tamperproof protected portion of the receptacle.

As illustrated in Figs. 2 and 4 of the drawing, when pressure is exerted on the lower or free end 40 of the tab I3, the wall of the receptacle or container, atthe incised area I2, is disrupted or broken, thereby permitting said portion of the wall, indicated at i2, to'move as a unit with the tab l3 and providing a pour opening l5. When the 5 tab i3 is re-engaged with the receptacle wall, the

severed portion M of the wall serves as a cap which refits snugly into the pour opening i5.

In the form of invention illustrated in Fig. 5, the tab I3 is secured to the receptacle by means 0 of a staple I6. Where this form of invention is used, the staple may be engaged with the receptacle immediately above the apex of the scored area l2.

In the form of invention illustrated in Fig. '7, the incised area I! may be circular instead of trialri gular thereby providing a round pour opening It is, 01. course, understood that various changes may be made in the details of construction, proportion and arrangement of parts within the scope oi the claims hereto appended.

What is claimed is:

1. A milk receptacle including an elongated paper body provided with an incised zone at its upper end, a tab extending across and engaged with said incised zone, and means for securing one end of the receptacle, said means engaging a terminal of the tab, the opposite terminal of the tab being free to operate for severing the incised zone of the body.

2. A milk container including a paper body the upper end of which is sealed and provided with a triangular shape incised zone, the apex of the zone issuing into said sealed end, and a tab one end of which is secured in said sealed end, said tab being superimposed on and engaged with the incised zone of the body, a part of the tab projecting beyond said zone to provide an operating portion for severing the incised zone from the body.

3. A paper receptacle for milk consisting of a body provided with an incised zone and equipped with machine sealed terminals, and means carried by one end of the body and operable to provide a pour opening by removal of the part of the receptacle within said incised zone, a part of said means being secured in one of said sealed ends, another part of said means providing a finger grip to permit operation of said means.

4. A liquid container having a paper wall which is cut or scored to provide a displaceable part permanently connected to the wall by an uncut portion which' comprises a hinge, and a separately formed tab attached to the outer surface of the container wall adjacent said hinge and also to the outersurface of said part, the hinge of thedisplaceable part being reinforced by a metallic JOSEPH L.
