Definitions

  • the invention relates to a cigarette shell , a method o f production thereof , and an assembly for storage and transportation thereof .
  • Unfilled cigarette shells known to the public as pre-rolled cigarette tubes are des irable among smokers who prefer to mix- and-match their own tobacco without having to roll their own cigarettes .
  • These unfilled cigarette shells have an appearance similar to a finished cigarette , but are without any tobacco or smokable material inside which makes their structure inherently weak and easily collapsible during storage and transport .
  • Even partially collapsed cigarettes shells become di f ficult to fill and can be rendered unusable .
  • Cone-shaped cigarettes are popular because as the cigarette burns the flavor tends to get progressively stronger .
  • a cone furthermore allows for more tobacco to be burned at the beginning than the end, allowing for an even f lavor .
  • the cigarette shell comprises : a hollow f rustoconical body defining a narrow end and a broad end; a tip provided within the narrow end of the body; and a removable insert in a nested pos ition with the body for supporting the body from the inside against collapse .
  • the presence of a nested insert wi ll forti fy the body against collapsing inwardly as pinching forces may be supported by the body onto the insert .
  • the insert may be chosen so as increase the total rigidity of the shell .
  • the insert has a portion that , when in the nested position, protrudes form the body, such as from the broad end, for being manually engaged by a user .
  • This protruding portion may even be furnished with a pull ing tab so as to further increase the ease with which the insert is engaged by a user .
  • the insert forms a chute for funneling a smokable into the body of the shell .
  • More speci fically thi s provides the body with a protective inner lining so as to protect the body against tearing during a processing of filling the shell with a smokable .
  • the insert i s made of a first sheet that is at least in part elastically deformed so as to , in the nested position, provide an outward pressure against a portion of the inner surface of the body above the tip .
  • the sheet may be curved along the inner surface of the body to form a protective inner lining that adapts to the local inner diameter of the body .
  • the first sheet may be curved such as to form at least one coil so that the insert is able to progress ively uncoil while being removed from the nested position through the broad end of the body so that during the removal the insert substantially maintains a pressure against an increasingly smaller portion of the inner surface of the body until it is fully removed .
  • the portion of the insert that is in contact with the body substantially not only retains the inner shape and si ze of the portion of the body with which it is engaged, but also allows the one part of the sheet to sl ide out from underneath another part .
  • the first sheet is coiled from a substantially square or trapezoidal shape , such as with rounded or cut edges , into a f rustoconical shape .
  • the hollow f rustoconical body is made of rolling paper with a thickness between 10-20 gsm, and wherein the first sheet is substantially made of a paper with a thickness that exceeds the thickness o f rolling paper, such as 21- 140 gsm, preferably 60- 90 gsm .
  • Thickness here is intended to mean areal density, instead of actual height in microns .
  • the term thickness and areal density are interchangeably used hereinafter .
  • the shape is substantially trapezoidal so as to prevent unnecessary overlap between paper portions which might otherwise add to surface friction . The trapezoidal shape thus saves on paper and promotes even uncoiling .
  • the shell may be nested with another shell like it so that the insert acts as a spacer between the body o f the shell and the body from the next shell nested .
  • the insert is pre ferably arranged as a chute .
  • the insert may simply be a ring or a series of connected rings .
  • the nesting of shells will also allow the shells lend support to each other against collapse , thus further increas ing the resi stance o f the shells against collapse . This means that inserts may be reduced in thickness and would stil l lend support due to the cumulative strength of inserts across at least a part of the series of nested shells .
  • the insert may have a broad end, and a narrow end, and wherein a portion of said narrow end is folded inwardly or crumpled .
  • this allows the inwardly folded portion to support a series of nested cigarette shells against compress ion in the length direction, as opposed to only protect against radial compression .
  • With certain insert pressure along the length direction of the shell may rip the shell . This occurs most commonly when a user holds a cone between index finger and thumb, such as for sselling the shell to friends . Or when one simply handles the cone too enthusiastically, such as during a filling process .
  • the crumpled variant can be produced by coiling the sheet of the insert , and tapping it on a surface , such as a table , with a distal end prior to its insertion into a hollow f rustoconical body with said distal end .
  • the inwardly folded variant can be produced by folding a precoiled sheet inwardly at its distal end, prior to insertion . Insertion being the insertion of the insert into a hollow f rustoconical body to form the shell .
  • the method for producing a cigarette shell comprises the steps of : providing the shell having a hollow f rustoconical body defining a narrow end and a broad end and wherein a tip is provided within the narrow end of the body; and providing a removable insert made of a first sheet ; elastically deforming the first sheet , such as into a coil , so that the de formed sheet f its into the broad end of the body; moving the insert into a nested position with the body for supporting the body from the inside against collapse .
  • the method wherein the insert forms a chute comprises the step of being nesting another shell with the shell by fitting a narrow end of the other shell into the broad end of the shell such that the insert spaces the body of the shell from a body of the other shell .
  • the spacer extends along at least a part of the length of both bodies .
  • an assembly of a trapezoidal box and a trapezoidal tray has upstanding lateral edges for reinforcing the sides of the box, wherein the tray i s foldable along its longitudinal l ine , such as through the middle of the tray, for forming an M-shaped slide .
  • the above may understood as fol lows .
  • the tray may as sume a tray configuration, in which the tray is U-shaped, and a slide configuration in which the tray is M-shaped .
  • the tray configuration is suitable for carrying a plurality of shells , or a plurality of series of nested shells , laid side by side .
  • the tray In the M-shaped configuration the tray can be used as a s lide for receiving smokables en for using it in the process of filling a cigarette shell as discussed herein above .
  • the upstanding lateral edges decrease in height along a direction of mutual convergence so that in cross-section the M-shape decreases in si ze from a first end to a second end thereof .
