Abstract
Abstract The apparatus disclosed herein is arranged to fill with liquid and seal a carton which has as its single means of access an orifice closable by a simple, flat flap punched from one side of the carton but remaining integral with that side. The cartons are delivered one by one and accumulated on a platform of the carton filling and sealing apparatus. After a predetermined number of cartons have been accumulated, they are moved into position beneath a storage tank for the liquid with which they are to be filled. The tank is lowered to bring spout-like appendages on the tank into penetrative relation to the orifices of the cartons. After the cartons have been so positioned, valve mechanism associated with the tank meters a quantity of liquid into the cartons. Each of the spout-like members has associated with it a suction tube for drawing off and returning to the liquid storage tank any froth that may develop during the pouring of the liquid into the cartons. After the cartons have been filled, the storage tank is raised, and the next group of cartons is moved into position to be filled, the cartons which have been filled being moved out of position by the newly presented cartons. As the filled cartons are moved out of position, the closure flap is deflected back generally into carton closing position and a sealing tape is applied over the flap.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
289 words
In an apparatus for transferring fluent material to cartons having a single access orifice: means for delivering empty cartons to said apparatus with the access orifice facing upwardly; an accumulation station for receiving and accumulating side by side a plurality of cartons delivered by said delivering means; means for storing said fluent material having a plurality of spout-like appendages through which to deliver fluent material to said cartons; a stationary platform disposed beneath said fluent material storing means; reciprocably movable pusher means for moving a plurality of accumulated cartons onto said stationary platform in positions of registry of their access orifices with said spout-like appendages and acting through the instrumentality of the empty cartons being moved into positions of registry of their access orifices with the spout-like appendages to move the filled cartons out of registry with the appendages and withdrawable to accommodate the accumulation of additional cartons side by side; means for causing the transfer of fluent material from the storing means through said spout-like appendages and orifices; means for driving said pusher means to and fro in reciprocatory movement; a roll for applying a length of orifice-closure tape over the access orifices of the filled cartons during movement of the filled cartons by the pusher means through the intermediate instrumentality of the empty cartons, said roll having a circumference at least as great as the length of the orificeclosure tape to be applied to a carton; means for preparatorily holding said lengths of tape in surface contact with the periphery of the roll; and means for imparting rotation to said roll at a peripheral velocity matching the linear velocity of the cartons for effecting a transfer of the lengths of tape From the roll to the cartons.
Claim 2
Dependent Claim
289 words
In an apparatus for transferring fluent material to cartons having a single access orifice: means for delivering empty cartons to said apparatus with the access orifice facing upwardly; an accumulation station for receiving and accumulating side by side a plurality of cartons delivered by said delivering means; means for storing said fluent material having a plurality of spout-like appendages through which to deliver fluent material to said cartons; a stationary platform disposed beneath said fluent material storing means; reciprocably movable pusher means for moving a plurality of accumulated cartons onto said stationary platform in positions of registry of their access orifices with said spout-like appendages and acting through the instrumentality of the empty cartons being moved into positions of registry of their access orifices with the spout-like appendages to move the filled cartons out of registry with the appendages and withdrawable to accommodate the accumulation of additional cartons side by side; means for causing the transfer of fluent material from the storing means through said spout-like appendages and orifices; means for driving said pusher means to and fro in reciprocatory movement; a roll for applying a length of orifice-closure tape over the access orifices of the filled cartons during movement of the filled cartons by the pusher means through the intermediate instrumentality of the empty cartons, said roll having a circumference at least as great as the length of the orificeclosure tape to be applied to a carton; means for preparatorily holding said lengths of tape in surface contact with the periphery of the roll; and means for imparting rotation to said roll at a peripheral velocity matching the linear velocity of the cartons for effecting a transfer of the lengths of tape From the roll to the cartons.
Claim 3
Dependent Claim
131 words
Apparatus in accordance with claim 1 in which the orifice-closure tape has a coating of heat-energizable adhesive substance on the surface to be applied to the carton and the carton has a coating of heat-energizable adhesive substance at least in the area to which the length of tape is to be applied, and wherein said means for preparatorily holding the lengths of tape in surface contact with the periphery of the roll comprises: a heat conductive body having a concave surface complementing the convexity of said roll for preparatorily heating the adhesive substance on the lengths of tape and a flat surface disposed above and in close proximity to the upper surface of waiting filled cartons for preparatarily heating the adhesive substance thereon; and means for heating said heat conductive body.
Claim 4
Dependent Claim
67 words
Apparatus in accordance with claim 2 in which: the location of the heat conductive body relative to the location of the fluent material storing means is such that the filled cartons in being moved out of registry with the spout-like appendages of the storing means by the pusher means through the intermediate instrumentality of the empty cartons are moved into heat-receiving association with the heat conductive body.
Claim 5
Dependent Claim
39 words
Apparatus in accordance with claim 1 in which: the means for imparting rotation to the roll includes a driving connection establishable between said pusher means and said roll to cause operation of said roll by said carton pusher means.
Claim 6
Dependent Claim
78 words
Apparatus in accordance with claim 4 wherein said establishable driving connection comprises: at least one pinion gear coaxially associated with said roll; a rack linked to said pusher means for imparting rotation to said pinion gear; and means for rendering said pinion gear effective to impart rotation to said roll only incident to movement of the pusher means in the direction in which it moves empty cartons into fluent material receiving relation to said fluent material storing means.
Claim 7
Dependent Claim
94 words
Apparatus in accordance with claim 5 wherein: the pinion gear is secured to said roll; the rack is so articulated to the pusher means as to accommodate presentation of the rack into and out of operative engagement with the pinion gear; and the means for rendering the pinion gear effective to impart rotation to the roll comprises an instrumentality for presenting the rack in engagement with the pinion gear incident to carton moving movement of the pusher means and for disengaging the rack from the pinion gear incident to withdrawal of the pusher means.
