17 claims. (c1. 21e-29) This invention relates to a machine for sealing packages and containers.

More particularly stated, the invention relates to a machine for applying a seal between a container and a closure, such for instance, as a seal for sealing the junction or adjoining parts of a vtobacco box and the lid for the box. As is-well known, such boxes must be sealed or the contents will dry out and will not be in suitable condition for use. At the present time packages of this type are entirely enclosed in a Wrapper of suitable sealing material, but when the outer wrapper is opened the seal is broken.

Many tobacco boxes are provided with hinged lids or caps which have a fairly tight fit except around the hinges where air leakage occurs.

This invention has for its object to provide a machine for sealing the lids or closures of containers of the type specied, the machine being simple and practical in construction and the seal being so applied that it may be easily broken when the package is to be opened.

Further objects of the invention will appear from the following specification taken in connection with the drawings which form a part of this application, and in which Fig. l is an elevational view partly in section of a machine constructed in accordance with the invention;

By sealing the closure in the manner outlined the vouter seal can be removed when the closure or lid is to be opened, leaving the inner seal which extends along the back of the container in position. This seal prevents air from leaking in around the hinge openings.

Further details of the invention will appear` from the following specification.

ithecan, as-shown at the right in Fig. 1.

sprocket wheels 34, 34 at one end of the machine.'

and sprocket wheels 35 at the other end thereof.. .I

The'cans or boxes C are beadedV at the bottom' thereof, as shown at 36, and achanneled guide..

way 31 is provided in the guide `bar 38 secured to n the rear plate 3| for guidingthe-cans-as they vare Y fed by the feeding members 32. The front-'end portions of the cans or containers are supported jthroughout the major -portionof their feeding movement 'on-the upper edge 39 of the plate 30.

i The'cans C maybe fed to the machine by a conveyor or,asshown in'Fig. 1, may be mounted Ain a'hopper 40 from which they-are fed by gravity between the successive feeding members 32 as the conveyor chains vand feeding-*members advance. l Y H The sealing strip S applied across'the ends and the bottom of the cans as they -are fed through 'the'v machine is carried by a supply yroll l 45 mounted on a'spindle 46 and-led upwardly around a guide roll 41 and a groovedfrollf48 to a position 4beneath-thepath of feeding movement of the cans. A grooved `roll 49is disposed above the 'path of movement of the cans and presses the cans downwardly against the upper surface of the sealing strip-which is supplied with an adhesive so that as a can engages the strip the strip'will adhere thereto. Therolls 48 and 49 l are grooved to' receivelthe vbead on the can.

AThe conveyor lchainsare driven intermittently Awith a `vv'slight' `dwell .1 between .the movements thereof,.the driving connections illustrated being asfollows:

shown particularly in Fig. 2.the1shaft 50 is driven in any suitablel mannerlas by a .motor Yand is providedwith afgear which meshes with -a gear 52 mounted on a shaft 53.. The face of the gear 52 has secured thereto four equally Yspaced rollers 54 which` coactfwith slots V55 of a Geneva wheel 56 which has a hub' 58 mounted on fthe shaft 51.On the hubV 58 aremounted the sprocket wheels 34,.34,.which support the .endless Acarriers or chains .33 `on which thefeedingmembers 32 are mounted.

" l'It will be evident from the form of driving connections above described .that the feeding mem- .bers will operate intermittently.l When the first 'can'is fed throughthe machine the front end of Tthe strip S is secured around the front edgesy of On .the next intermittent feed the can moves to the position shown in Fig. 5 on an enlarged .scale, in which position the strip S is severed and the vrear end thereof is folded around the rear end portions `of the can.. This is accomplishedin the following manner:` 1 f I 1- 'A block 60 is provided with a downwardly extending l"guide portionu 6| slidably mounted in a- "guideway 62 and vertically reciprocatable in the 'fbllowingmannem The portion 6| 'has pivoted l thereto at 63 a link 64'. which isals-o pivoted to a pin|5 carriedby' aneccentric disk 66 rotatablyv mounted on shaft 61'.

At the upper end of the block 60 there is clamped to the right hand side edge thereof a knife 10. The block 60 i-s then raised in a manner hereinafter described by the rotation of the eccentric disk 66 and the strip S will be severed by the knife 10. The knife 10 has two right angle blades forming a cross and the blade 1| forms slits in the strip, as shown in Fig. 17. The block 60 also carries at the upper left hand end thereof a triangular shaped presserf12 which is grooved to receive the bead on the can and has a resilient or cushion facing 13. rlhis presser is de- .signed to fit between the advance end of one can and the rear end of the can in front of said can and to press the ends of the sealing strip S .A against the ends of the can, as shown at the left in Fig. 5. 'Ihis takes place as the block 60 is raised. 1 c The'l shaft 61 is driven in the following manner: Shaft 53, as above stated, has mounted Ythereon a gear 52 which meshes with a gear 15 carried by a shaft 16. y -This gear-15 meshes with agear 18 carried by a shaft 19. l

The gear 18 meshes with a .gear 8| carried byfa shaft 82.V `Gear 8| also meshes with a'gear 84 mounted. on a -shaft- 85.v Gear 84 also meshes with a gear 81 mountedon ashaft A88. The latter gear `81 meshes Ywith a gear 89 mounted on a sleeve andl gear 89 drives a gear 9| mounted on av shaft 92. The gear 9|-also meshes with a `gear 93 carried by the shaftl.

During the Ioperation ofthe block60 the can is held down by a bar..95iwhich is carried by arms 96V and 91-which may,'iff.des'ired, be adjustably mounted. The bar 'has a ledge 96 which, as shownparticularly inv Fig. '1, engages the upper end surface of the lid of the canand holds the can in position as the flexible elastic. saddle 12 vpresses the. sealing strip against. thebottom adjoining portions of the lid and can.

The bar 95 also has extending longitudinally thereof a groove 99 in which is disposed a tearingA strip T which is vmounted on va supply spool |00. The strip extends downwardly passing through an eye |0| disposed at the end of an arm |02 secured at |03 tothe bar 95. From the eye |0'| the-tearing stripr T passes around a `fgrooved roller |04, through the groove 99, over a grooved roller |05 disposed at the other end ofthe bar 95 -and beneath. a guiding member .|06 which `is also carried bythe bar 95. I The sealing. strip S' for sealing the top of the can 'and lid as the Canis passed through the m-achine is carried by a supply roll' I0 mounted on a lever. carried by a bracket. I2, a second supply roll ||3 being mountedpnthe other end of the lever.

The striptSy is carrieddownwardly overa lgrooved or channeled roller I4 carried by a bell crank yleveril |5 carried by a sleeve ||5 mounted on'ashaft |16. .Theother end of a bell crank lever has mounted thereon a grooved roller ||1 .formed of resilientmaterial,'such as rubber, and the strip S' extends around the roller ||1 and is secured to the advance end of the can. vIt will Vbe noted particularly from the showing in Fig, 10

that the tearing stripTispositioned beneath .crank lever |20 which has connectedto one end thereof a spring |2| xed at |22 t'o the back "plate of the machine.

The other endof the hellfcranklever |20 is connected by a'link |23 to an'` arrn |24 mounted on a-iixedpivot |25. v` The arm |24carries a roller |28 which engages a cam |21 carried by the sleeve 90. As the cam is rotated the roller and arm |24 will be raised and the link |23 will cause the bell crank lever |20 to be swung in an anticlockwise direction against the tension of the spring |2|, thus causing thebell crank lever l5 to be swung in a corresponding direction, raising the roller 1. When the roller |26 engages the low portion of the cam |21 the spring |2| will cause the bell crank levers to swing in a clockwise direction or from the position shown in Fig. 11 to the posi tion shown in Fig. 10, and even further in a clockwise direction until the roller ||1 engages the back of strip S and faces the strip against the back of the container or can C. The can C is thus held firmly between rollers ||1 and as it is fed forwardly by the chain.

The sealing strip S is pulled downwardly and a downward pull is exerted on the tearing strip T in the following manner:

As shown particularly in Fig. 4, a block is slidably mounted on a plate 30 and a roller |3| is mounted on a stud carried by the block |30, the stud extending through a slot in the plate 30. The roller |i3| engages a cam |32 mounted on the sleeve 90. Springs |33 exert a downward pull on the block |50 and maintain the roller |3| in engagement with the cam |32.

The block |30 has secured thereto and extending upwardly therefrom a bracket |55, the upper which as the part |36 is moved downwardly in the manner herein described form longitudinal slits |38 in the sealing strip S'. This strip, as will be hereinafter described, is severed intermediate the ends of the slits |39 and these slits are disposed at the edges of the tearing strip T and facilitate the initial tearing operation.

The block |30 has pivoted thereon at |40 a bell crank lever |4| having a finger |42 at the upper end thereof adapted to move inwardly between the sealing strip S' and the tearing strip T, a's shown in Fig. l1. The bell crank lever |4| has slidably mounted therein, as shown at |43, a pair of telescoping studs |44 and |45 which are spring pressed in opposite directions by means of a spring |46. These studs have heads |41 at the outer ends which engage vertical guides |48 and operate in the following manner as the block |30 is moved upwardly and downwardly.

When the cam |21 has caused the bell crank lever H to swing in an anticlockwise direction to the position shown in Fig. 11, the arm |38 will be disposed above the tearing strip S and the bell crank lever |4| and finger |42 will be disposed in the dotted line position shown in Fig. 4. As the cam |32 permits the springs |83 to pull downwardly on the block the friction between the heads |41 and the guides |48 will cause the bell crank lever |4| to swing in a clockwise direction, thus moving the finger |42 to the position shown in full lines in Fig. 4 or above the thetearing stripwill be severed in the manner about to be described. When the block moves upwardly under action of the cam |32 the lever |4| will swing outwardly, as shown in dotted lines in Fig. 4.

During this movement the strip S will be engaged by rollers |50 and |5|, the cans being supported on grooved rollers |52 and |53.

The severing operation is accomplished by Ameans of a knife blade |54 carried by an arm |55. having an angularly disposed portion |55 mounted on a shaft |51. Shaft |51 is driven by a spiral gear connection |58, |59 to shaft 85. The spiral gears are so timed that although the shaft |51 is rotated continuously the knife |54 will come into operation at the proper time in th-e sequence of operation of the machine to sever the strip S and the tearing strip T. Since the tearing strip is pulled downwardly a greater distance than the strip S' the ends of the tearing strip will extend beyond the ends of the sealing strip S.

After the severing operation just described has been completed the cans move to the next posim tion of movement in which the final operation takes place, namely, the pressing of the ends of the upper sealing strip S against the ends of the can and over the ends of the lower sealing strip S. This is accomplished in the following manner: i

A block A|50 is slidably mounted in guideways i8! and has pivoted thereto at |52 a link |53, 4the other end of which is pivoted to a pin |54 on a disk |05 mounted on the shaft 19.

The block has extending upwardly therefrom a bracket or post and this bracket, as shown in Fig, has a transverse block |51 at the upper end thereof, to the outer ends of which are pivcted at |68 a pair of lever arms |39. The arms |59 have clamped thereto by clamping members |10 the ends of a iiexible strip of material |1|.

The lever arms |50 are normally swung on their pivots |58 to positions in which the lower ends are outwardly disposed and the upper ends are inwardly disposed, this being accomplished by means of springs |18, the outer ends of which are secured to the upper ends of the arms |10 and the inner ends of which are secured to the bracket |55 and |13. f

When the can is disposed beneath the transverse block |61 at the upper end of the arm |66 and beneath the iiexible strip |1|, the block |60 will be lowered causing the strip |1| to engage the sealing strip S and to press the sealing strip tightly against the junction between the lid of the can and the can. Moreover, during the downwardrnovement of the block and strip |1| the lower ends of the levers |88 will be pulled inwardly, thus firmly pressing the ends of the sealing strip S against the ends of the can. In this manner the sealing strip S will vbe rmly secured in sealing position.

In Figs. 22-24 inclusive, there is illustrated a modified form of construction for folding and pressing the ends of the outer sealing strip S' around the ends of the can or container.

In this modification the presser carried by the vertically reciprocatable slide |50 is simplified. The bracket |01 at the top of the slide has secured thereto a pair of blocks |15 and |16, generally triangular in shape, and provided with a resilient cushion or facing |11 engageable with the ends of the severed strip S for pressing said ends against andaround the ends of the can and cover and in overlapping relation to the en'ds of the inner strip S. f

'The block |68 is reciprocated in the same manner as the block |68 in the first form of the invention illustrated, Y

In the'form of the invention illustrated in Figs. 22-24 inclusive, further means is provided for securing and sealing the ends of the sealing strips around the ends of the can' and the can cover. From the pressers |15 and |16 and from the discharge end of the feed conveyor'the cans are pushed by a pair of arms |18, |19 carried by a sleeve |88 into radially disposed pockets |8|,

|82, |83, and |84 carried by a spider or hub |85 mounted on a shaft |86. The pockets are dis posed 90 apart around the hub |85.

The sleeve |88 is mounted on a pin |81 slidably mounted in a slot |88 formed in the plate 3|. Flanges |89 and |98 are mounted on the shaft or pin 81 on opposite sides of the plate 3|.

The end of the pin or shaft |81 is mounted in a block |9| slidably mounted in one end of the lever |92 which is pivoted on the shaft 53` and has slidably mounted in its opposite end a block |93 having a pin |94 mounted on a disk |95 carried by the shaft 58.

As the shaft 58 rotates the lever |92 will -be oscillated, thus causing the arms |18 and |19 to engage the rear upper ends of the cans as they are delivered by the can conveyor, whereby the cans will be successivelypushed into-the pocket ISI-|84 carried by the spider |85.

The shaft |86 and the spider |85 is driven in the following manner: Shaft 51 has mounted thereon a bevel gear |91 which meshes with a bevel gear |98 carried by a shaft |99. Shaft |99 has also secured thereto a gear 288 which meshes .with a gear 28| which in turn meshes with a kgear 282 mounted on the shaft |86.

4 Since the shaft 51 is driven intermittently and controls the drive of the feed chain, the shaft |86 will also be rotated intermittently in synchronism. with the drive of the chain which feeds the cans. In the foregoing manner the cans are delivered successively to the pocketsand each pocket has mounted in its outer end a spring strip 285 which engages the end of the can having the cover thereon and positions and holds the can in the pocket.

After a can has been fed into the pocket |8`| viewing Fig. 23 the spider |85 is rotated through 90 to position the pocket ll and the can therein the position of the pocket |82 in Fig. 23. When the can reaches this position a fmal squeeze or pressure is applied to the ends of the fouter strip S and also to the ends of the inner strip S by means which will now be described.

This pressure is applied by arms 286 and 281 mounted on shafts 288 and 289 and provided on their free ends with resilient pads or cushions 2id shaped to fit around the ends of the can.

The shafts 288 and 289 are driven in the following manner: The eccentric |95 on the shaft 58 is enclosed by an eccentric strap 2|| carried ,by a pitman rod 2|2, the other end of the rod being pivoted at 2|3 to an arm 2|'4 secured to a shaftll, The shaft 2|5 has mounted thereon a gear 2|6 which meshes with gears 2l1 and 2|8 carried by the shafts 288 and 289. Thus, the arms 286 and 281 will be oscillated, the operation `being timed to swing the arms inwardly to engage the pads or cushions 2|8 with the outer ends of After the pressing operation just described has the strip S and to press the strip firmly Yand securely against the outer ends of the can.

pressing position the can is discharged from the pocket by means of a'plunger head 228 mounted on a plunger 22| secured to the carriage-222. The carriage 222 is reciprocated by the shaft |81.

Fig. 16 illustrates in plan view the upper sealing strip S and it will be noted that the strip is slit at |39 to facilitate the initial tearing thereof by the tearing strip T.

Fig. 17 shows the lower sealing strip S with slits |15 at the ends. These slits facilitate opening of the lid or closure.

Fig. 18 is a somewhat diagrammatic view show-v ing the positions of the two sealing strips S and S and the tearing strip T before these strips are folded around the ends of the can and secured in position.

Fig. 19 is la cross sectional view through the can, lid and sealing strips, illustrating the completed positions of these various strips.

Operation The operation of the machine may be briefly summarized as follows: The tearing strip S is led upwardly from the supply roll 45 and to a position below the path of movement of the cans from the hopper 48. When the machine is started the front end of the strip S will be secured to the front edge portion of the first can. As the can moves to its next succeeding position the block 6| will be raised causing the flexible elastic member 1.3 to press the sealing strip S firmly in position against the end portions of the can, the strip having been severed by the knife 12.

As the can passes from this position the tearing strip T is led'over the can and to a position beneath the upper sealing strip S'. The bell crank lever |I5 will be swung in an anticlockwise direction raising the roller ||1 to the position shown in Fig. 11. The arm |36 will be disposed above the strip S and as the arm moves downwardly the finger |42 will move inwardly to a position above the tearing strip T and the strip S and the tearing strip will be pulled downwardly to the position shown in Fig. 10. During this downward pull the knives |31 and |38 will form slits |39 in the strip S.

The can next moves to a position in which the knife |54 engages the strips S and T and severs v vthese strips leaving the ends of the strips extending downwardly and outwardly. From this severing position the can moves to its last position in the machine in which the flexible member |1| and the pivoted arms |69 press the strip in sealing relation against the upper surface of the can and press the ends of the strip inwardly against the ends of the can and in overlapping relation to the ends 0f the lower strip S.

With the form of the invention illustrated in Figs. 22-24 inclusive, the cans are operated on by the pressing means |15 and |16 mounted at the upper end of the slide |68 and are thereafter fed by the arms |18 and |19 into the pockets of the spider |85. The ends of the sealingstrips are then given a further pressing operation by the arms 286 and 281 and the sealed cans are thereafter discharged from the pockets `by the plunger head 228.

When the can is to be opened the tearing strip ing position and covers the openings formed by the hinge at the back of the can, thus preventing air leakage. It will be understood that the remaining portion of the lid has a vfairly ltight seal when the lid is closed.
