Abstract:
A flask-shaped package or container for packaging smoking articles, such as cigarettes, has a generally parallelepiped shape with slightly curved front and back body panels. The container comprises a body and a lid integrally molded in one-piece of a plastic material with an open bottom having an internal peripheral shoulder and a base made of a separate plastic/metal foil laminate that is bonded to the shoulder by induction heating a heat-activated adhesive covering the metal foil of the base. The body has a central internal front-to-back stiffening rib and an access opening in its top and front panels with a surrounding ledge to which is adhesively bonded a removable foil closure. After the access opening is closed with the foil closure, cigarettes are inserted into the container body through the open bottom thereof. A protective paperboard liner that prevents adherence between the heat-activated adhesive and the cigarettes is inserted into the open bottom and supported by the central rib and the cigarettes. The base laminate is then inserted into the open bottom and bears on the shoulder so that when the adhesive is activated by induction heating, the base bonds to the shoulder and seals the container. An adhesive-backed label wrap with brand specific indicia is applied to the outer surfaces of the container.

Description:
FIELD OF THE INVENTION 
     The present invention relates to packages and containers for cigarettes and a method for packaging cigarettes, the container having a flask-shaped design and being made of a durable plastic material to preserve the freshness of the cigarette contents of the container and to protect the cigarettes from being crushed. 
     BACKGROUND OF THE INVENTION 
     Cigarette packages and containers that protect the cigarettes from crushing and/or preserve the freshness of the cigarettes are known in the prior art. Typically, such prior art packages are box-shaped containers made of a paper or cardstock material in either a “softpack” or “hardpack” form. While some designs of the softpack package are capable of retaining a measure of freshness, the softpack package offers little or no protection against crushing. Similarly, some designs of the hardpack package help to preserve freshness to some extent and offer some protection against crushing, however, the cardstock materials that are typically used are vulnerable to damage and crushing under moderate loads. An example of a hardpack package is shown in U.S. Pat. No. 6,164,444 to Bray et al., which discloses a typical hinged-lid, box-shaped container that is made from a “rigid card material.” Further examples of cigarette or tobacco packages made of a paper or cardstock material are disclosed in U.S. Pat. Nos. 1,496,474; 2,960,264; 5,044,550; and 5,097,948. 
     Other materials, such as metals, woods and plastic, have also been suggested for making crushproof and freshness-preserving cigarette containers, but have never attained widespread acceptance because of their typically high manufacturing costs. However, with the advancement of plastic manufacturing technology, it has become more cost effective for cigarette manufacturers to use plastic materials for cigarette containers. U.S. Pat. Nos. 2,867,369 to Cernera and 3,223,275 to Rice, Jr. disclose cigarette containers that may be made out of various materials, such as plastic, wood, metal and cardboard. However, neither Rice, Jr. nor Cernera take advantage of the inherent design and manufacturing versatility of plastic material because they contemplate cigarette container designs that are suitable for construction from wood, metal and paper, as well as plastic. 
     Paper or cardstock materials alone are not well-suited to preserving the freshness of the contents of a cigarette container because those materials generally do not provide a sufficiently air-tight or air-impermeable barrier. Typically, softpack and hardpack cigarette packages employ inner or outer wraps of metal foil/paper laminates, metallized paper or plastic wrappers, or low permeability transparent polymeric sheet overwraps to protect the freshness and aroma of packaged cigarettes and other smoking article products. However, the use of a plastic container molded from a polymeric material having a relatively high permeability would eliminate the need to use such wrappers and overwraps or, alternatively, in conjunction with such wrappers and overwraps, the air impermeability of molded plastic containers would be further enhanced. 
     It would therefore be desirable to provide a cigarette container made of a plastic material that protects the contents from accidental crushing and takes advantage of the other benefits of using a plastic material in a cigarette package. 
     SUMMARY OF THE INVENTION 
     The present invention is directed to a novel “crush-proof” plastic cigarette container that has a relatively thin, contoured shape with rounded corners that is easy for the consumer to handle and carry. Although the cigarette container of the invention may be configured in a number of forms that are not specifically illustrated herein, a preferred embodiment of the invention comprises a six-sided box with rounded corners, the front and back body panels of which are slightly curved to form a flask-shaped container that conforms generally to the contours of the human body. 
     The curved, flask-shape of the container also helps to distinguish the cigarette product from the cigarette products of other manufacturers, thereby increasing product identification with consumers. In addition to brand names and trademarks, the unique packaging of the present invention will help consumers identify the product origin and/or manufacturer. The curved body panels and rounded corners also increase the strength and rigidity of the container because they resist bending and flexing better than a container having flat body panels, particularly under the vacuum packing conditions of the container of the present invention. 
     The container is preferably configured with a relatively narrow front-to-back profile so that twenty cigarettes can be arranged in a 10-10 configuration, that is, two rows of ten cigarettes each. This gives the container a slimmer profile than the conventional box-shaped container which holds twenty cigarettes in a 7-6-7 configuration, i.e., three rows of seven, six, and seven cigarettes. The slight curve and narrow profile of the flask-shaped container accommodates the natural curves of the human hand and body so that it is easy to grasp in the hand and fits comfortably inside a shirt, coat or pant pocket. Although a container designed for the 10-10 cigarette configuration is preferred, other cigarette configurations are also possible, such as, for example, the conventional 7-6-7 configuration or other configurations with more or less than twenty cigarettes. 
     The container is preferably made of three components, namely, a lid and a body, which are preferably molded together in one piece of a plastic material, such as polypropylene, and a flat base that is preferably die-cut from a flat sheet of a plastic/metal, e.g., a polypropylene/aluminum foil laminate or injection molded of a plastic material, e.g., polypropylene, with a metal foil substrate, such as aluminum foil, bonded to one surface thereof. The body is molded with an open bottom and four panels, i.e., a front, back and two side panels, with a central stiffening rib integrally formed with and extending between the front and back panels. The body is molded with the lid in the open position connected to the body by integrally molded hinges. The body is also molded with an access opening in the top and the upper portion of the front panel through which the cigarettes packed in the container are removed. 
     The lid is formed with several panels which are integrally and hingedly molded to the top of the container body and is reclosable after opening to help maintain the freshness of the cigarettes contents of the container. Inner surfaces of the lid side panels are molded with longitudinal grooves or depressions which are adapted to engage in a “snap-fit” manner with corresponding longitudinal ridges or protrusions on the confronting side panels of the container body to maintain the lid in a secure closed position. Alternatively, the grooves and ridges may be molded on the body and lid, respectively. When the lid is closed, it is flush on all sides with the body of the container to provide a smooth surface onto which a label containing trademarks, logos, advertisements, product information or other printed or embossed indicia may be placed or adhered. The label substrate may be may be paper, metal foil, a single- or multi-layer polymeric film or the like. The paper or polymeric film may be metallized with an aluminum metal, for example. A preferred label is an adhesive-backed metallized paper. 
     As previously mentioned, the bottom of the as-molded container is open and includes a recessed shoulder or ledge around its internal perimeter on which the base of the container bears when it is inserted into the open bottom of the container body after the cigarettes are loaded in the body through the open bottom. A heat-activated adhesive is applied to the surface of the metal (aluminum) foil of the flat laminate sheet or the injection molded base so as to cover the entire inwardly facing foil surface of the base. A separate paper or paperboard sheet having the same shape, but a slightly smaller area than the metal foil and base is positioned between the heat-activated adhesive surface of the base and the ends of the cigarettes to provide a protective liner or barrier between the ends of the cigarettes in the container and the heat-activated adhesive of the base and thereby prevent the cigarettes from sticking to the adhesive when it is activated by heat. Because the paperboard liner has a smaller area than the base, it does not bear on the shoulder or ledge at the bottom of the body, but is dimensioned so that it will fit inside the bottom of the container body below the shoulder or ledge. 
     A sheet material, preferably a metal foil, is adhesively bonded over the access opening in the top and front panel of the body and the lid is then closed. With the container lid closed and the bottom open and oriented upwardly, a batch of twenty cigarettes is loaded into the container body through the upwardly open bottom of the container body. The paperboard protective liner is then inserted into the open bottom of the body past the shoulder and is supported on the cigarette ends and the central molded rib of the body. The base is then inserted into the open bottom of the container body with the heat-activated adhesive surface around the edge of the base bearing on and in contact with the shoulder or ledge of the plastic body. The bottom end of the container is then induction heated for a period of time to activate the adhesive in contact with the shoulder and form an adhesive bond between the shoulder of the plastic body and the base. Should the heat-activated adhesive be activated in an area greater than the portion that is in contact with the shoulder, the paper or paperboard protective liner prevents the adhesive from adhering to the tobacco or the cigarette paper at the ends of the cigarettes in the container. The heat-activated adhesive may also be applied to the thin perimetrical edge of the base that confronts the sidewall of the open end of the container body. Upon activation of the adhesive, the edge of the base will also bond to the sidewall of the body. 
     The induction heating device for heat-sealing the base to the container body comprises a sealer head made of a non- or low-heat conducting material in which is formed a cavity corresponding in size and geometrical shape to the container. A coil is wound inside the sealer head about the cavity and is energized by electrical energy to generate heat in the cavity. When a container is positioned in the cavity, the coil is energized to a level that causes the heat-activated adhesive only on the edges of the base in contact with the shoulder to be activated. 
     Although the bonding technique described above is preferred and is one important aspect of the present invention, other techniques may be employed to bond the base in the open end of the container body without departing from the intended scope of the invention. For example, instead of bonding the base to the body with a heat-activated adhesive, the contacting portions of the plastic of the base and body may be bonded by other types of adhesives, by ultrasonic or laser welding or other techniques that will be apparent to those of skill in the art. 
    
    
     With the foregoing and other advantages and features of the invention that will become hereinafter apparent, the nature of the invention may be more clearly understood by reference to the following detailed description of the invention, the appended claims and the views illustrated in the drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now to the drawings in detail, FIGS. 1 and 2 are front perspective views of the container  100  of the present invention in the closed and open positions. Although the container may be used to hold or package a variety of items, the preferred embodiment of the invention is a container for packaging cigarettes. The orientation of the cigarettes C in the container is such that the filters of the filter cigarettes are oriented toward the top panel of the container, and the bottom panel of the container is the side of the container opposite the top panel. The front and back of the container are the two sides of the container having the greatest surface area, and the remaining two opposite sides or end panels extend between and connect the front and back and the top and bottom. 
     The container  100  is a generally rectangular flask-shaped box or parallelepiped having a slightly convexly curved front panel  122  and a slightly concavely curved back panel  124 . The curved front  122  and back  124  body panels increase the container&#39;s strength and rigidity because they better resist bending and flexing as compared to a container having flat or planar body panels. 
     The container has a narrow profile that is designed to hold twenty cigarettes, preferably in a 10-10 configuration, that is, two rows of ten, although other packing configurations and numbers of cigarettes are contemplated within the scope of the invention. The curved shape and narrow profile conform to the natural curves of a person&#39;s hand and body so that the container is easy to grasp and easily fits into a shirt, coat or pant pocket. In addition, the flask-shape of the container helps to distinguish it from other cigarette containers currently available, utilizing the unique design of the container to enhance product identification with the consumer. 
     The container comprises three main components, the lid  110 , the body  120 , and the base  130 . All three parts of the container are preferably made of a plastic material having a low permeability that protects the contents of the container from being crushed and preserves the freshness and aroma of the cigarettes. The lid  110  and body  120  are preferably molded together in one piece with the lid in the open position and connected to the body by integral hinges. The flat base  130  is preferably die-cut from a flat sheet of a plastic/aluminum foil laminate or injection molded of a plastic material with an aluminum metal foil substrate bonded to one surface thereof. Although the most preferred material for the container is a moldable and die-cuttable polymeric material, such as an injection-moldable polypropylene, it is contemplated that the container body and base could be made of other materials, including paperboard, wood, tin, aluminum or other metals without departing from the scope of the invention. 
     Each part of the container will now be described in greater detail with particular reference to FIGS. 1-4. The body  120  is a four-sided box comprising rectangularly-shaped front and back fin, panels  122 ,  124 , respectively, and side panels  126 ,  128 . The lid  110  has a flat top  112 , a slightly curved, rectangularly-shaped front panel  114  and a pair of triangularly-shaped side panels  310  and  410 . The curvature of the front panel  114  matches the curvature of the front body panel  122  to present a smooth surface. The lid  110  is pivotably or hingedly attached to the top of the body  120  by a pair of so-called “living” hinges  212  integrally molded between and connecting the lid  110  and the body  120  at the upper and outermost portions of the back panel of the body. The hinges  212  are narrow flat straps, as best seen in FIGS. 2 and 5, which bend back-and-forth as the lid is pivoted between the open and closed positions. The base  130  is a separately formed multi-layer flat plate that is sealingly affixed in the open bottom end  131  (FIGS. 11 and 12) of the container body  120  after the cigarettes C have been inserted into the body  120 . 
     As best seen in FIG. 2, the upper portion of the body  120  is molded with a recessed portion  220  which forms an edge  222  along the front, sides and back of the body that mates with a corresponding edge  224  of the lid  110  and supports the lid when it is in the closed position. A cutout or depression  225  is provided in the edge  222  on the front panel  122  for a purpose to be described. At both sides (only one shown) of the recessed portion  220 , there are molded a pair of longitudinal protrusions or ridges  226 . The inside surfaces of the triangular lid sides  310  and  410  are provided with corresponding pairs of recesses or grooves  228  which lockingly engage with the ridges  226  to securely hold the lid in the closed position. FIG. 6 shows an enlarged cross-sectional view of the protrusions  226  on the left side of the recessed portion  220  engaging in the grooves  228  on the left inside surface of the lid side  310 . This arrangement of protrusions and grooves may also be provided on the right side of the recessed portion and the inside surface of the lid side  410 . Although the preferred embodiment of the invention shows protrusions and grooves for securing the lid in a closed position on both sides of the lid, protrusions and grooves need be provided on only one side of the lid or other lid securing means may be used without departing from the scope of the invention. 
     The recessed portion  220  is a molded extension of the body  120 , and is recessed from the outermost surfaces of the panels  122 ,  124 ,  126 ,  128  so that it can fit inside the lid  110  while still allowing for smooth transitional surfaces, i.e., flushness, between the outermost surfaces of the lid  110  and the body  120  when the lid is closed. The recessed portion  220  of the body has an L-shaped access opening  230  in the top and front panel thereof so that the cigarettes C in the container can be accessed and removed by the consumer. The opening  230  is completely surrounded by a shoulder or ledge  232 . A sheet material  234 , such as a metal foil sheet or laminate  234 , preferably an aluminum foil, is adhesively affixed to the shoulder  232  to close and seal the opening  230  over the cigarettes C and provide a substantially impermeable barrier over the opening to help maintain the freshness and aroma of the cigarettes C. The foil sheet  234  has a tab  236  which may extend into the cutout  225 , but which is preferably creased at the bottom edge  238  of the sheet  234  and folded upwardly over the front surface of the sheet  234  before the lid is closed for loading of the cigarettes into the container. Instead of the foil sheet  234 , the opening  230  may be closed by a thin, integrally molded polymeric membrane (not shown) that is removed or fractured by the consumer to access the cigarettes C. 
     The cutout  225  facilitates opening of the lid  110  by the consumer by exposing a central portion of the edge  224  of lid front panel  114  when the lid  110  is in the closed position (FIG.  7 ). The consumer may, for example, use a finger or fingernail to engage the exposed edge  224  and lift the lid upwardly from the closed position shown in FIG. 1 to the open position shown in FIG.  2 . 
     Referring to FIG. 7 the container  100  is provided with a central rib  710  which reinforces the front and back body panels  122  and  124  and further prevents the container body  120  from being crushed with consequent damage to the cigarettes C contained therein. The rib  710  also advantageously provides support for maintaining the dimensions of the cavity in the container body during loading of the cigarettes into the body, as well as support for the body during vacuum packing of the container. The support rib  710  divides the interior of the container into two equally sized chambers, with each chamber holding two rows of five cigarettes (5-5) in the embodiment shown. The top portion  712  of the rib has an L-shape so that the two chambers of the container are in communication with one another and their contents are easier to access. The inside surface of the body  120  is provided with a perimetrical shoulder  714  adjacent the open bottom  131  (as shown in FIGS. 11 and 12) of the body. The base  130  fits inside the bottom end of the body  120  and its perimetrical edge engages the shoulder  714  and is separated from the bottom  716  of the rib  710  by a paper or paperboard insert or liner  718  with a perimetrical edge  720 . The sheet  718  forms a protective liner between the cigarettes C in the package and the base  130  as described in more detail hereinafter. 
     FIG. 8 illustrates the construction of the base  130  which comprises a flat plate  800  approximately 1 millimeter thick with a perimeter that corresponds to the inside perimeter of the body  120  below the shoulder  714 . The plate  800  is preferably die-cut from a laminate comprising a polypropylene sheet  801  laminated to a metal foil substrate  804  with an adhesive or bonding agent  802 . The plate  800  may also be injection molded with the metal foil substrate  804  subsequently bonded thereto. A heat-activated adhesive  806  is applied to the entire upper surface of the metal foil  804  and may also be applied to the edge  805  of the plate  800 . The size and shape of the paper or paperboard liner  718  relative to the plate  800  is shown by the dashed lines in FIG.  8 . The difference in size of the liner  718  and plate  800  leaves a narrow perimetrical strip or border  810  of the heat-activated adhesive  806  that engages the shoulder  714 . The metal foil  804  is preferably an aluminum foil with a thickness in the range of about 0.0015 inch to about 0.005 inch, preferably about 0.003 inch. 
     The base  130  is attached to the bottom of the container body  120  as shown in FIG.  9 . FIGS. 11 and 12 show the bottom of the container body  120  with the base  130  removed to illustrate the open bottom  131 . With the open bottom  131  of the container body oriented upwardly, the cigarettes C are loaded or inserted into the two chambers of the body. The paperboard protective liner  718  is then inserted into the open bottom  131  and is supported on the ends of the cigarettes and the bottom  716  of the rib (FIG.  7 ). Because of its smaller size, the liner  718  passes through the bottom rim  900  of the body  120  and the edge  720  thereof abuts the inside wall  901  of the body adjacent the shoulder  714 . The plate  800  is then urged into the bottom rim  900  of the body so that the surface of the heat-activated adhesive  806  bears in close contact with the shoulder  714 . The outermost surface of the plate  800  is flush with the end surface  902  of the body to permit tax stamping of the container on the bottom thereof. 
     After the plate  800  is inserted, the container  100  is then placed in an appropriately shaped cavity of the sealer head of an induction heating device (not shown). The induction heating device is energized and the container is induction heated at the bottom end thereof to activate the adhesive  806  only at the edge region  810  (FIG. 8) and bond the base plate  800  to the shoulder  714  of the body. If heat-activated adhesive has been applied to the perimetrical edge  805  of the plate  800 , the edge  805  will also bond to the inside wall of the rim  900 . In the event the induction heating process activates the adhesive  806  inwardly beyond the edge region  810 , the protective liner  718  prevents the adhesive  806  from coming into contact with and sticking to the ends of the cigarettes C in the container. 
     The aluminum foil  804  advantageously functions as a heat sink for absorbing the heat of induction and rapidly melting the heat-activated adhesive  806  in the edge region  810 . The induction heating process is preferably conducted in a vacuum chamber at a pressure in a range of about 10 to 20 inches of water. After the container is removed from the sealer head and cooled, the base is securely bonded to the base thereby producing a vacuum-sealed cigarette package. Vacuum-filling processes other than a vacuum chamber may also be used as will be apparent to those skilled in the art. 
     A preferred heat-activated adhesive for use in the preferred embodiment of the invention is an adhesive sold by Protect-all, Inc. of Darien, Wis. under the designation P-1004, however, as those skilled in the art will appreciate, other suitable heat-activated adhesives may be used. 
     It is contemplated according to the invention that the cigarettes may be packaged in the container without vacuum sealing, however, vacuum sealing advantageously helps to maintain the freshness and shelf life of the cigarettes as well as the perception of freshness. When sealed with a sufficient vacuum, the initial opening of the container of the invention will produce an audible sound of air rushing into the container indicating to the consumer the vacuum packaging of the container and the freshness associated with vacuum packaging. 
     The plastic material from which the container base is die-cut or injection molded is preferably polypropylene. The container body and lid are also preferably an injection moldable polypropylene. Polypropylene is relatively gas impermeable as compared with other reasonably cost-effective moldable polymeric materials, however, other polymeric materials, such as, for example, high density polyethylene, may be used. To improve the impermeability of the plastic container, the molded polypropylene container body, lid and base may be treated with a low permeability coating, such as an epoxy amid. Alternatively, the polymeric resin from which the container is made may be a crystallized plastic molding which is a stronger plastic and a better gas barrier then a non-crystallized plastic. Typically, for example, when polyethylene terephthalate (PET) is injection molded, it is left in the amorphous state because it is transparent in that state. However, if the PET is crystallized, it is an opaque white material and its strength and effectiveness as a gas barrier is substantially increased. To crystallize the plastic, the PET is heated to approximately 120 degrees Celsius for about 30 seconds in its desired shape. Alternatively, rather than using PET or other polymeric resin that requires a crystallization step, a more expensive, but inherently highly crystalline resin, such as polyethylene vinyl alcohol (PVA), can be used as the gas impermeable injection molded plastic for the container. 
     Another way to improve the impermeability of the plastic container  100  is to cover all or most of the external surfaces of the container with a metal foil, such as an aluminum foil. 
     FIG. 10 illustrates a sheet or blank  180  which forms the printed and/or embossed label  150  that is adhered to the front, sides and back of the container  100 . The label  150  is preferably an adhesive-backed metallized paper but may be made of other materials, such as a metal foil, a metallized polymeric film or the like. The edge  152  of the label  150  is placed on the container starting at the rear corner edge of the left side  126  of the container body (FIG. 1) and is adhered to the side  126  of the body, the front panels  122 ,  114  of the body and lid, the side  128  of the body and the back panel  124  of the body until the edge  154  meets, overlaps or is slightly spaced from the edge  152  (FIG.  3 ). Cut-outs  158  and  159  are provided on the label  150  so that the lid sides  310 ,  410  are not covered by the label (FIGS.  3 - 4 ). A perforation line  156  extends between the cut-outs  158  and  159  for a purpose to be described. Adhesive-backed metallized paper strips  160  (FIG.  1 ),  170  (FIG. 9) may also be applied to the top panel  112  of the lid and the outer surface of the base  130 . Preferably, the metallized label  150  and the metallized strips  160 ,  170  are provided with printed and/or embossed product information, trademarks, logos, and the like. Tax stamping may be applied to the strip  170 . 
     The label  150  covers the cutout  225  on the front of the body and the joints  127 ,  129  between the lid  110  and the body  120 . To open the container, the consumer uses a fingernail, coin or other object to break the label  150  along the perforation line  156 , then engages the now-exposed lower edge  224  of the lid  110  and raises the lid to the open position shown in FIG.  2 . The consumer then grasps the tab  236  of foil  234  and pulls it outwardly and upwardly to detach the foil  234  from the front and sides of the ledge  232  and expose the cigarettes C for access. It will be appreciated that the foil  234  may be left adhered to the rear portion of the ledge  232  so that it may be repositioned over the opening after a cigarette C has been removed from the container. In this way, the cigarette container may be opened and the contents removed by the consumer without the need to discard any portion of the container. 
     The above-described cigarette container  100  provides a combination of advantages for a cigarette package, some, but not all of which may exist in prior art cigarette packages. In particular, the cigarette container  100  has an improved ergonomic curved and slimmer shape with rounded edges for handling comfort, ease and comfort of carrying in a pocket and product differentiation; a reclosable and resealable lid; a vacuum-sealed package with an audible “freshness” sound when the container is opened; readily recyclable materials; improved structural strength to prevent crushing; an easily printed or embossed metallized label which also functions as a gas barrier; and reduced consumer waste upon opening. 
     It is contemplated, although not necessary according to the invention, to overwrap the container  100  with a further conventional overwrap film having a tear tape (not shown).
