19 Claims. 1
My invention is a package provided with an opening pull-strip, which is preferably attached to both a closure member of an inner shell and to an outer sheath. In such a package, the pullstrip is so positioned and attached that it acts as a guide for removing an area of the sheath over the closure member and thereby provides clearance for the free unfolding of such member.
My invention is particularly applicable to a cigarette package or similar portable container having an end closure normal to the body of the package, and which may be only partially opened to form a spout by pulling the pull-strip attached to the closure. The pull-strip is so attached to the closure that continuance of pulling, after the spout is opened, peels the pull-strip from the spout and completely detaches the pull-strip from the package without mutilation of the latter.
In one embodiment of my invention, a group of cigarettes or other rod-like articles, are housed within a soft shell formed from an inner wrapper or foil telescoped within a jacket or encircling label having a sealed end and an open end. The end of the inner shell adjacent to the open end of the jacket has its closure formed from a pair of narrow flaps and a pair of wide flaps containing slits. The narrow flaps are folded to form tucks overlaid by the wide flaps with their slits adjacent to the inner end of one of the tucks; and as used herein the term tuck designates the portion of the end closure formed from a foldeddown extension of one of the narrower side walls of the pouch.
The tuck adjacent to the slits in the flaps has a pull-strip peelably connected thereto near its inner end. The pull-strip extends from such point of attachment toward the side of the package and is preferably bent over, parallel with its attached section, and attached to a sheeted cellulose acetate (cellophane) wrap. In such construction the pull-strip is overlaid by and overlies the folded wide flaps and may overlie a stamp or sticker which is secured to the jacket for holding the flaps in closed position.
My invention also comprises a method of making such a package by folding blanks to form a shell composed of an inner wrapper partially encased in a jacket and having a slitted extension projecting therefrom; filling the shell thus formed; bonding a pull-strip to a section of the inner-wrapper-extension; and folding the extension, adjacent to the top edge of the jacket, to form a tuck from the portion to which the pullstrip is attached and to form wide flaps from the portions containing slits. The wide flaps have sections partially overlying the tuck and pull-strip and the slits in such flaps are disposed adjacent to the inner edge of the tuck.
The surfaces of the flap sections are not attached to the tuck surface or to the pull-strip section which they overlie, but such flap sections may be yieldingly held in place by an overlying edge section of a revenue stamp, or the like, attached to the jacket. Consequently, when the pull-strip is pulled, the inner edge of the tuck is raised, due to the resistance to shear of the pullstrip bond, and moves the overlying flap sections from beneath the edge of the stamp, and the tuck and flap sections turn upward along their crease junctions with the wrapper body. Continued pulling peels the pull-strip from the tuck surface, due to the change in the angle at which the stress is then applied to the bond.
A package so formed is preferably sheathed in an outer wrap. The sheath tends to impede the unfolding of the closure members, and to overcome this, the sheath may be slit to facilitate tearing off a section thereof (covering the unfoldable closure members) along spaced tear lines. Such sheaths are commonly formed from sheeted cellulose acetate (cellophane) in which tear lines tend to converge together within a short distance unless guided by a crease or underlying tear strip. Such convergence must be prevented,
' as otherwise residual flaps of cellophane overlying the unfoldable closure members may obstruct the unfolding of such members and cause premature peeling of the pull-strip.
Convergence of the tear lines may be prevented in various ways. For instance, the sheath may be provided with a zip tape encircling the package so that when the zip-tape is pulled a section of the sheath is severed. Or a preformed slit may be so positioned in the cellophane sheath that a tear initiated from one end of the slit and extending transversely of the slit will be intersected by a pull-strip section attached to the underside of the top of the sheath whereas a complementary tear initiated from the other end of the preformed slit and extending transversely of the slit will pass the pull-strip section and will be intersected by a crease at the far side of the top of the sheath. The crease and pull-strip edge will then guide the tear along the top of the package so as to uncover the unfoldable members, but leaving the opposite tuck covered by a section of the outer wrapper so as to lock it on the package.
The torn off section of the outer wrapper may be used as a grip for pulling on the pull-strip and thereby lifting the uncovered tuck and the separable flap sections folded thereover to form a species of spout without disturbing the contents of the package.
The principles of my invention and the best modes in which I have contemplated applying such principles will further appear. from the following description and the accompanying drawing in illustration thereof:

In the packaging of cigarettes, for example, an inner shell is formed on each former 4 from a rectangular wrapper blank 5, which, in accordance with my invention contains slits 6 and I inclined inward from the edge 3 of the blank and convergingtoward one another when the blank is flat.
Such wrapper blanks may consist of any desired type of sheet material but are preferably made from strips of laminated paper and metal foil whose exterior surface may be wholly or partly coated with a soluble or thermotropic, colorless, tasteless and odorless coating 5', such as a vinyl lacquer.
In making a wrapper blank, a laminated strip is preferably cut to form the slit 6 before the severance of the wrapper blank from a strip, and the strip is then cut to simultaneously form the slit i and sever the wrapper blank from the strip along the line 9.
The slitting and severance of a wrapper blank may be performed in any desired manner but is conveniently effected, as shown in Fig. 1, by feeding a laminated strip over conventional rollers it into the path of a cutter H having short diagonal end blades i2 and i3 and an intermediate long blade It. When the laminated strip and cutter are brought into cutting relationship, the blade I2 cuts a diagonal slit 8 in an unsevered section of the strip; the blade l4 severs a section from the strip to form a wrapper blank 5 and simultaneously with such severance the blade i3 cuts a slit i in the wrapper blank 5 being severed; such wrapper 5 already containing a slit 6 cut during the severance of a preceding wrapper blank.
The blank 5 is bent circumferentiallyaround the former 4, with the coated surface outside, if the blank is coated, and the juxtaposed transverse edges of the wrapper 5 form a seam Ma. The portion of the wrapper 5 projecting beyond the outer end of the former 4 may be tucked and folded in any usual manner to form a bottom closure [5 for the soft shell thus formed from the wrapper 5, as shown in Fig. 2. The slits 6 and i were so positioned in the blank as to positionthem in substantial alignment on op.- posite sides of the soft shell formed on the former by the wrapping of the blank 5 thereon.
The initially formed soft shell may be sheathed in a jacket or printed label by bending a. sec.- ond wrapper blank iii, of somewhat less width than the wrapper 5, circumferentially around the initial soft shell on the former 4, as indicated in Figs. 2 and 3. The juxtaposed transverse edges of the wrapper blank iii are adhesively connected tov form a seam it near one of the longitudinal edges of the package.
The outer end of the wrapper blank i6 may be tucked in any usual manner, as for instance by tuckers l8, and the flaps between the tucks then folded and secured together.
By combining the shell and jacket there is provided a double walled pouch on the former 4.
After thepouch has been formed, a. pull-strip 21" is bonded to the protruding edge section of the wrapper'fi between the slits. 6. and l- The pullstrip preferably comprises a strip of heat-sealing cellulose acetate (cellophane) which may have one face coated with a coating 2|, such as a thermoplastic vinyl lacquer, or a soluble adhesive, to facilitate attachment of the strip securely to metal foil to supplement a coating on the foil or take the place thereof when an uncoated wrapper is used. The bonding coating on the wrapper or pull-strip, or both, may be rendered tacky by the application of heat immediately prior to, or after, bringing the wrapper and pull-strip into contact, or a solvent fluid adhesive .may be applied to form a tacky spot immediately preceding contact. The pouch may be filled with cigarettes in any usual manner before or after the attachment of the pull-strip.
As illustrated diagrammatically in Fig. 5, an adhesive spot 2|] may be formed on the end extension of the inner shell by an oscillating, hollow tool 26a through which a drop of solvent may be deposited upon a wrapper having a soluble coating, or heat may be applied to a wrapper having a thermotropic coating. The pullstrip 2|, with or without the coating 2|, may be laid on the jacket I6 and on the tacky spot on the extension of the wrapper 5 and pressure applied thereto as indicated in Fig. 5A: or a pull-strip may be laid on an end extension of the wrapper 5 and on the jacket l6, and pullstrip and extension bonded together by the application of heat by a thermostatically controlled electric heater and presser, as indicated in Fig. 5B; one or both of the members to which heat is applied being thermotropic or having a thermotropic coating.
The pull-strip 2! may be laid on the jacket and projecting section of the inner shell in any suitable manner, and after or without the prior formation of a tacky spot 20, but is preferably projected from the open end of the shell toward the closed end of the jacket when a loaded former 4 is moved into alignment with a tape-shooting, tape-severing, and pressing or heating attachment applied to a conventional packer.
As illustrated in Figs. 5 and 6, this attachment includes a bracket 22 which is mounted on a usual housing (not shown) which normally overlies the rearwardly extending portion of the turrel I of the conventional cigarette packer, and the feeding mechanism of the attachment is preferably aligned with the position commonly designated station XII of such packer.
The tape feeding mechanism preferably comprises a pair of peripheral contacting feed rollers 23 and 24 for intermittently advancing the pull tape 2|; a cutter 25 for cutting from the tape 2| a length sufficient for a pull after delivery thereof to a package at position XII, and a pair of spaced presser fingers 2S and 2?. The finger 26 is moved into engagement with the front of the pull-strip 2| and presses it against the jacket immediately before the severance of the tape by the cutter 25 and the arm 2'? moves the opposite end of the pull-strip against the extending end of the wrapper 5 immediately after severance of the pullstrip and holds the latter until it is firmly tacked. The arm 2'! may be heated to expedite drying an adhesive solution or to activate a thermotropic bonding material. As indicated in Fig. 53, a presser foot 21a may be substituted for the presser arm 2'! and heated by an electric coil 2'") controlled by a thermostat 210.
The finger 26 may be manipulated by the shaft 26' and lever 26" and the members 25 and 21 by a sleeve 21 and lever2'l.
Preferably the tape 2| is creased longitudinally (Fig. 5) before being fed to the rollers 23 and 24 so as to impart to the tape a tendency to assume a channel shape or V-cross section imparting greater longitudinal rigidity to the tape.
The feed wheel 23 is fixed to a shaft 28 which is journalled to a swinging arm 29 fulcrumed on the bracket 22. The shaft 28 has a gear 30 fixed to an end thereof. The feed wheel 24 is fixed on a shaft 3| journalled in a bearing 32. The shaft 3| has fixed thereon a gear 33 meshing with the gear 39 and a bevel gear 34 connected with a driving source (not shown). The arm 29 is normally biased downwardly by its own weight or by a spring 35 to regulate the traction between the peripheries of the feed wheels 23 and 24.
The gears 33 and 30 mesh with one another to effect their simultaneous rotation, and may be manually positioned relatively by lifting the arm 29 to regulate the initial position of the wheels 23 and 24 relative to the tape 2!. The length of thetape fed per revolution of the wheels 23 and 24 may be varied by the use of feed wheels of dilferent diameters.
During the projection of the tape 2 I, it is supported above the wrapper extension by the shear bar 35 which is adapted to coact with the cutter 25 to shear the tape as soon as an appropriate length thereof has been delivered. The free end of the tape is meanwhile held by the finger 26 and the severed end is engaged and pressed by the finger 21 against the adhesive spot 2!] or the spot it is to be tacked by the bonding thermotropic coating.
Immediately following these operations, a plunger 35 is advanced against the cigarette bundle H; to bottom these in the shell formed by the inner wrapper and to then strip the package from the former 4. This movement transfers the filled package into the entrance of the usual delivery guideway of a conventional cigarette packer, indicated in dotted lines in Fig. 9, and into position to be acted upon by tuckers 36 and 3?, while the pull-strip 2| is held against the package by a keeper 38. The stripped former 4 is now ready for the positioning and cutting of a new wrapper 5 and for a cycle of operations by which a pouch is formed and filled with cigarettes in the usual manner and a pull-strip attached thereto in accordance with my invention.
The tuckers 3G and 3? simultaneously bend a section of the strip 2| and the sides of the protruding section of the wrapper 5 perpendicularly to their former positions so as to form tucks 39 and 40. The inner edge 4| of the tuck 39 is adjacent to the slits l, as shown in Fig. 8. Flaps 42 and 43, formed by the front and back of the projecting section of the wrapper 5, are then folded over as shown in Fig. 9 so as to partially overlie the pull-strip 2| and the tucks 39 and 4!]. A revenue stamp or sticker 44 is adhesively attached to the front and back of the jacket IE to form a bight overlying the flaps 42 and 43; one edge portion of the stamp 44 overlying the slits 1 whose outer ends terminate adjacent to the edge of the stamp, and at or slightly below the top edge of the package, as shown in Fig. 10. Tapering portions of the severed flap sections 42 and 43' are thus overlaid by the stamp 44 but may be readily withdrawn therefrom.
In the preferred form of my invention, the pullstrip section projecting from between the flap sections 42' and 43 is bent over upon itself as indicated in Fig. 10A. The bent over section may be tacked to the. flap members 42', 43' if the latter are coated. While the pull-strip is thus bent so as to overlie the flaps 42 and s3 and the stamp 44, with a coated section 2i thereof exposed, it is covered by the bight 45 of an end wrap 46, preferably composed of a sheet of transparent waterrepellent cellulose acetate, or where the sidewrap sheath is used, as shown in Fig. 21, the strip 2| may be folded over before or during the application of the sheath.
The cellulose sheet 43 may be tucked and folded, as shown in. Figs. 11 and 12, to form a protective casing which has a slit ll in the front panel thereof. The slit is isolated by a wax frame 48. The bight' 45 and pull-strip 2i are securely connected to one another, preferably by the'application of a heated element 49 thereto to cause thermal fusion of the strip and/or wrap.
The slit ii is so positioned on the front of the sheath formed by the wrapper 46 of the end-wrap package that a tear line started at one end of the slit and extending around the top of the package will intersect the pull 2!, and a tear line starting from the other end of the slit and extending around the top of the package will clear the end of the pull 2i, as indicated in Figs. 14 and 15.
As shown in Figs. 13 to 19 inclusive, such a package may be readily opened by inserting a thumb nail into the slit 4'! and initiating tears of the sheet 46 at the ends of the slit ii and through the wax frame 48. The left hand tear line (Fig. 14) will continue until it reaches the crease along the back edge of the top and will turn to the right and follow such crease. The course of the right hand tear line will be interrupted by the edge of the attached pull strip 2! and will turn to the right and follow such edge. Movement of the pull-strip toward the right, breaks any light bond there may be between it and the closure by a peeling action and tears off an area of the bight section of the wrapper 35 to uncover the fiap sections 52 and t3 and the tuck 39 and provides a grip facilitating the pulling of the strip 2! to lift the tuck 3i) and withdraw the flap section 42' and 43' from beneath the edge of the stamp M and splits any bond there. Ihe removal of the sheath section between tear lines permits free unfolding of the tuck 39 and flap sections 42' and 43 along their creases or hinge lines adjacent to the edge of the jacket it so as to form a spout which may be refolded to reclose the package or may be torn off as shown in Fig. 19. The continued pulling of the pull 2| after turning the tuck 39 on its crease line readily peels the pull from the tuck, without disturbing the contents of the package, as indicated in Fig. 18. The bond between the pull-strip and tuck strongly resists sheer when the direction of pull is substantially parallel with the plane of the surfaces of the pull-strip and tuck but the bond is readily split by a pull transverse to such plans to cause the peeling of the pull-stri from the tuck.
It will be noted that the left hand end of the slit 51 is spaced from the edge of the package and that when the cellophane cover 56 is torn it leaves a narrow rim of the cellophane wrap over the top of the tuck as and flaps folded thereover so as to retain the cellophane wrap on the package and retain in place the tuck 4B and the flaps overlying it.
As illustrated in Fig. 20, the tearing of the cellophane wrap may be initiated by substituting a slit 47c. and wax isolating frame 480; in the side of the cellophane wrap and extending the end of a wide pull-strip 2| to a position adjacent to such slit. When the thumb nail. is inserted in the slit 47a to tear the cellophanev and lift a tongue thereof which can be grasped, the strip 2|, which is bonded to the inside of the cellophane wrap, acts as a guide for tearing. a wide strip out of the top of the cellophane wrap to permit the unfolding of the tuck and flap sections as above described without substantial impedance by the cellophane wrap.
In Fig. 21 there is illustrated the application. of a side wrap cellophane. cover 49 and rip tape 50 to a package embodying my pull-strip 2| and severed flap sections 42' and 43'. In both Figs. 12, 20 and 21, the pull-strip is bonded to the tuck 39 as above described and is bonded to the cello- 'phane wrap where the pull-strip is to both rupture the sheath and open the package. But where the sheath is independently ruptured, as in the form shown in Fig. 21, it is not essential to bond the sheath and pull-tape together since the latter is of sufficient size to itself provide a firm grip.
However, where a package embodying the pullstrip 2| and slit flaps 42 and 43 is enclosed in a side wrap sheath 49 provided with a zip tape 50, as shown in Fig. 21, the opening of the package is greatly facilitated by bonding the pull strip 2| to the top of the sheath, so that upon severing the top from the body of the sheath by pulling the encircling zip tape 58, the detached top remains attached to the strip 2 and provides a grip for setting in motion the series of progressive package opening stages shown in Figs. 15-19.
