APPARATUS FOR MAKING PAPER CONTAINERS Application filed March 25, 1929. Serial No. 349,767.
This invention relates to apparatus for forming paper containers, of the type comprising a body substantially tubular or conical, with a flanged bottom inserted into one end and secured by rolling or spinning the flange and the body end.-
The object of the present invention is to provide a ledge or shoulder in the body near the end portion, to receive the edge of the body flange member as inserted, and
facilitates the rolling, or spinning of these the sleeve will inclose the end portion '10 0 two members. In the accompanying drawings showing oneembodiment of my inven-- tion; Fig. 1 isa horizontal section through the device.
Fig. 2 is a section enlarged through the part engaging the container. Fig. 3 is a plan view partly in section showing further details of the apparatus.
Fig. 4 is a detail of operating mechanism for the forming device.
As shown in Figs. 1 and 2, the body portion of the container, here shown as conical, is placed in a holder 7 havin a conical bore 8 corresponding to the b0 y, and which body is shown as projecting beyond the end wall 9 of the holder by a'portion 10, the holder being smaller than the body to permit itsinsertionin just this position.
A plunger 11 slides in guide blocks 12, 13, and a coil spring 14: pressed between a collar 15 on the plunger, and the block 12 will resist inward movement of the plunger.
At its forward end the plunger is secured to a head 16 of-cylindrical shape whose outer end portion 17 may be slightly reduced, and which is of a diameter slightly greater than the opening or bore of the end wall 10 of the holder 7. A sleeve 18 slides at its bore on the'head 16, with an apertured end wall 19 slidable on the plunger 12; A coil spring 20 is compressed between the sleeve end 19 and a collar 21 fast on the i plunger 11. The latter will force the sleevesee Fig. 1, this end will registerwith this annular space and will pass therein as the head and sleeve, now in the relative positions shown in Fig. 1,, advance. Since the sleeve normally projects beyond the head the body, and the plunger is advanced to bring the sleeve end wall against the end wall 9 of the holder as shown in Fig. 2, that will arrest the sleeve. But the continued advance of the plunger will carry the head 16 forward from its normal position inside of the sleeve as in Fig.1, and the head will pass inside of the body projecting end 10, that is conical. The end of the head is the same size as the extremity of the conical body, and as the head will now advance through the arrested sleeve by advance of the plunger, permitted by comparession of spring 20, the cylindrical head will'move into the conical body end, that is of decreased diameter. And therefore the body end portion must expand, permitted by the annular space between the head and the bore of the sleeve. Continued advance of thehead through the sleeve will take place until the head presses the body, now expanded against the end wall 9, whose bore is slightly smaller than the head. This will result in a ledge or shoulder being formed between the outer portion of the head at the end, and the wall 9 of the holder, as clearly shown in Fig. 2. And it will be further seen that beyond this shoulder the body portion is now substantially cylindrical. This will better adapt the body to receive the end member, in the form of 'a flanged cup, that is.inserted into this expanded end of the body, until the body disc portion engages this shoulder.
The general operation of the machine is indicated in Fig. 3, where the bodies are formed at 30 and fed into theholders that are carried on an endless chain. At an advanced station 31 the flanged cap member .is inserted in the body in the holder; and at a further advance station 32 the body and the flanged bottom are rolled together by a spinning operation. The present invention is applied at the station 33 before the holders reach thestation 31 to receive the bottom, and here the body is treated to form the shoulder and enlarged end portion, by the mechanism shown in Fig. l and the several devices are driven from a main shaft 34 and a cam 35 onthis shaft engages the roller 36 on the end of the plunger 11, with a slotted guide 37 that straddles the shaft 34, the spring 1 1 pressing the plunger roller against the cam.
A machine of this character is shown in the patent to Stanley 1,628,074. In thesaid Stanley apparatus a shoulder is not formed in the body prior to the insertion of'the bottom, but when the bottom is forced in by a plunger-head, the. flanged bottom is caused by the head to expand the body outwardly into a shoulder in the holder. A similar arrangement is shown in other patents. With the present invention however,
a shoulder is formed in the body previous to the insertion of the flanged bottom, and facilitiates the operation of the machine.
What I claim is 1. In a machine for forming paper containers with a flanged bottom inserted and secured in one end of a body, the combinat1on with a carrier for the body that is advanced to bring the body to a certain station, means at one station for inserting a bottom in the body and means at an advanced station to secure the bottom in the body end ortion, of means at a station in advance 0' said stations to engage the body before the insertion of the bottom which means is arranged to impart a special shapmg to the body end portion adapted to 'receive the bottom and facilitate the securing of the bottom in the container.
2. In a machine for forming paper containers with a flanged bottom inserted and secured in one end of a body, the combination with a carrier for the bodies that is advanced to bring the body to certain stations, means at one station for inserting the.
bottom in the body and means at an advanced station to secure the bottom in the body end portion, of means at a station in advance of said stations to engage the body before the insertion of the bottom which means 1s arranged to impart a special shaping to the body end portion to form an innerledge, adapted to receive the bottom and facilltate the securing of the bottom in the container. 3. In a machine for forming paper contamers of conical form with a flanged bottom inserted and secured in one end of a body, the combination with a carrier for the body that is advanced to bring the body to tainers of conical form with a flanged bottom inserted and secured on one end of the body, the combination with a carrier for the bodies that is advanced to bring the bod1es to a certain station, means at one station for inserting the bottom in the bodies and means at an advanced station to secure the bottom in the body end portion, of means at a station in advance of said stations to engage the conical body end portion before the-m sertion of the bottom, whichmeans is arranged'to impart a special. shaping to the body end portion to form an 1nner ledge adapted to receive the bottom and facilitate the securing of the bottom in the body.
