The present disclosure concerns dispenser packages. The packages are primarily for products that come in a sheet or film form. The disclosure particularly concerns disposable packages which can be repeatedly opened and closed, during use, as individual sheets or films are dispensed. A particular application is in the area of packages for breath films.
For film or sheet products, such as breath films or other oral care strips, the product packaging preferably serves numerous purposes including:
One example of current oral care strip product available on the market is the “Cool Mint Listerine PocketPaks” product available from Warner-Lambert Consumer Health Care, Morris Plains, N.J. The product packaging for this product involves a cardboard or paperboard slipcover (about 3 and ⅝ inches by about 3 inches) having enclosed therein and removable there from, another cardboard or paperboard piece (about 3 and ⅜ inches by about 2 and 15/16 inches) having a blister pack attached thereto. After the second piece is removed from the slipcover, it is torn open by removal of a panel (about 1 and 5/16 inches by about 1 and ⅞ inches) in the cardboard or paperboard packing. Underneath the removable panel, a barrier film or metallized sheet is encountered which, once tom open or removed, allows access to inside of the blister pack. Contained within the blister pack is a plastic dispenser (about 1 and ⅛ inches by about 1 and ⅞ inches) which can be removed. The remainder of the package is discarded. The dispenser has a hinged panel selectively opened (and reclosed) with a tab, that allows access to internally received oral care strips.
In general, improvement in such packaging is desirable.
According to the present disclosure a package arrangement is provided which includes a receptacle and backing construction. In general the receptacle has an outer peripheral rim thereon, and the backing construction comprises a flexible film having releasable pressure sensitive adhesive on a first side thereof. In general, the backing construction is secured to the receptacle, by contact between the pressure sensitive adhesive in the outer peripheral rim. Products such as sheet materials are typically stored within the receptacle, and are covered by the backing construction.
The backing construction includes an openable and recloseable hinge cover portion therein. The hinge cover portion is generally formed by cuts or die cuts through the flexible film. The die cuts are generally parallel to one another in preferred embodiments, to form a flexible openable and recloseable cover in the backing construction. In preferred embodiments the cuts terminate in curved stops, to facilitate the opening/closing operation without undesirable tearing of the hinge cover portion from a remainder of the backing construction.
In a preferred embodiment a removable reinforced header portion is provided in the packet, which header portion is typically torn from the remainder of the package prior to opening of the package. In preferred arrangements, the header portion comprises a relatively rigid piece of cardboard or plastic, secured to a portion of the backing construction. In some embodiments a tamper evident strip is positioned between the header and the outer peripheral rim on the receptacle, to provide security.
According to the present disclosure a method is provided of dispensing articles from a package. In general the method involves opening and reclosing a package generally as characterized above.
Also according to the disclosure methods of assembly are provided, generally involving assembling the parts characterized above, in a preferred and operational manner.
In general, the present disclosure concerns a package arrangement for storing, handling and dispensing sheet materials (such as water soluble breath films or other edible films) normally dispensed in a sheet form. Of course other products can be continued in the package, but it is designed to be particularly convenient for such materials.
Packaging for such materials is provided in a “pocket/purse size”, i.e., a size that can be conveniently fit in a pocket, purse or similar space. Typically and preferably such arrangements have a size of no larger than about 2 inches by 4 inches, and a depth of no greater than about 0.75 inch. Typical preferred sizes of the packaging, after purchase and after removed of any discardable header, i.e., when stored in the pocket, is a size no greater than about 2 inches by about 2.75 inches. More preferably the depth of the packaging is no greater than about 0.40 inches.
Preferred packaging features according to the present disclosure provide the following:
In many applications, preferably a tamper evident sealing is provided, since the products to be dispensed are, often, intended to be ingested. Also, in many applications it is preferred that the material chosen for the packaging be such as to ensure proper protection of the internally received product(s) with respect to shelf life, for example low moisture vapor transmission.
In the drawings, described in detail below, a particular arrangement which accomplishes all of the above preferred features is provided. It is noted that unless specifically otherwise characterized, there is no requirement that all of the advantageous features feasible with the techniques described herein must be implemented in all products constructed in accord with the general principles provided herein.
Referring to
In the particular arrangement 1 depicted, the header 7 is a removable header piece that, after purchase and before the package 1 is to be stored in a purse or pocket, is torn or separated from the remainder of the package 15,
The particular package arrangement depicted
The backing 6 is preferably constructed in a manner such that a portion 6B of it,
A. The Reservoir or Receptacle 5
Of course, the reservoir or receptacle 5 can be formed from a variety of materials. It is anticipated that for a typical preferred application, the receptacle 5 will comprise a thermoformed or vacuum formed plastic material, and can be made as a “blister pack” construction 17 (
Referring to
Other features of the blister pack 17 will generally be selected to be convenient and inexpensive for manufacture, and to allow for ease of stacking, packing and handling. The particular arrangement shown, the blister pack reservoir interior 18A,
In general, the rim area 19,
B. The Backing Construction 6
In general, as indicated above, the backing construction 6 includes two portions 6A and 6B, FIG. 2. Portion 6A generally forms a portion of the header 7, and is removed from the package arrangement 1 in normal operation, FIG. 3. Backing construction portion 6B generally remains with the package 15 after removal of the header 7,
In typical embodiments, the backing construction 6 will generally comprise a strong flexible film having one side completely coated with a pressure sensitive adhesive (PSA). Preferably a resealable PSA is used, so that portions can be stripped away from blister pack 18 during opening and then be securely reclosed, conveniently. Typically the material for backing construction 6 is purchased from a supplier of resealable films, i.e., as a film having PSA already provided thereon. Usable materials include, for example: Flexicon optiflex PP200 H clear TC-332 EXV-133 TRACrite 100, a polydefin available from Flexcon, Spencer, Mass. is desired (covered by a holographic material such as Avery Dennison 95902 2.6M WH BOPP TC/R195/40#SCK). However, any other recloseable PSA that is a direct or indirect food grade material that reseals up to 40 times without adhesive residue can be used.
To provide for preferred operation,
Preferably, perimeter portions 38, 39 and 40 include exposed pressure sensitive adhesive (PSA) coating on the side toward the blister pack 18 to secure the backing construction portion 6B in package 15, more specifically to rim 19 of blister pack 17. The term “exposed” in this context, is meant to refer to a portion of the pressure sensitive adhesive field which directly contacts, and thus provides resealable adherence to, the blister pack 17. This would be by contrast to a “covered” area of pressure sensitive adhesive, as described below, which is permanently covered up by some material and thus is prevented from contacting certain structure.
Preferably, the exposed pressure sensitive adhesive in perimeter portions 38, 39 and 40 and the size of portions 38, 39, 40 is selected to engage rim 19 while leaving inner border area 45,
Another important feature of hinged cover portion 36 is cuts 53, 54, FIG. 3. The cuts 53, 54 are die cuts through backing portion 6B to form opposite side edges 56, 57 of hinged cover portion 36, FIG. 6. Cuts 53, 54 terminate at ends 60, 61, FIG. 3. During use, tab 35 is grabbed and hinged portion 36 is stripped away from receptacle 5, until ends 60, 61 of cuts 53, 54, respectively, are reached,
Preferably ends 60, 61 each include a tear stop 63 thereat, FIG. 4. For the particular embodiment shown in
In a typical embodiment for an oral care strip, the length of cuts 53, 54, prior to the curved end stops 63,
Still further alternate configurations of curved stops, as tear stops 63, are usable. Two such alternate arrangements are shown in
As indicated above, a typical preferred backing construction 6,
(a) a substrate or film 72; and
(b) a resealable pressure sensitive adhesive field 73 completely covering one side 74 of the substrate 72.
In general, the preferred substrate/PSA combination used will be shaped in the form of the entire outline or footprint of the backing construction 6. In general the “outline” or “footprint” of the backing construction 6 will sometimes be referred to herein as the “peripheral definition” of the package arrangement 1. The peripheral definition for the arrangement 1 depicted in the drawings,
Herein the notches 80 are referred to as V-shaped notches, despite of the fact for the preferred embodiment depicted they comprise two curves joined at a vertex, each being convex relative to the other. In general they each do define a V-shape, and facilitate tearing of the header piece 7 for the remainder of the arrangement 1, FIG. 1.
A deadening pad or film 85,
In
In general, the peripheral definition of the preferred deadening film 85, i.e., the shape of the deadening film, merely needs to be such as to conveniently cover the bowl or receptacle 5 and to engage a portion of the rim 19, with adequate overlap. Typical configurations will be rectangular, since typical bowls 5 will be rectangular in definition at the location inside of the rim 19. Of course a variety of alternative shapes are possible.
Attention is now directed to FIG. 6. Tab 35 includes, on side 89, deadening piece 89A. This piece 89A covers a portion of the pressure sensitive adhesive 73, to ensure that side 90 of tab 35 is not tacky to the touch. When the preferred package arrangement 1 is assembled, piece 89A comprises a residual portion of the rigid material used to form header 7. This will be described below, in connection with the detailed description of the header 7.
C. The Header 7
The typical header 7,
A typical usable material for piece 100 is a 5 to 10 mil cardboard or paperboard tag, or a styrene tag. The material chosen is preferably one that can be printed on one or both sides. The particular header 7 depicted in
Edge notches 80 are located between header piece 100 and front edge 19A of rim 19. The notches 100 facilitate tearing the header 7 from the remainder of the package 15, FIG. 3. To facilitate this tearing:
1. Deadening piece 100 is provided with a line of weakening, for example it is scored, partially die cut, or provided with a perforated line, generally along line 105,
2. A die cut is provided along line 106,
Note that line 106, terminates at opposite side edges 77 and 78, at edge notches 80. Also, the preferred shape of lines 105, 106 is such as to provide for a protruding tab portion 35, in the resulting package 15, after the tearing occurs. Preferably tab 35 projects outwardly from edge 110,
Attention is now directed to FIG. 11. In
For the tamper resistant seal strip 150 a variety of materials can be used. Typically a permanent pressure sensitive adhesive, as opposed to a resealable adhesive, on a printable label stock will work. The strip material will generally indicate if the package has been opened.
Attention is now directed to FIG. 12.
(a) backing construction 6, including region 6A and 6B;
(b) deadening piece 85;
(c) stack 10 of sheets 10A;
(d) header piece 7 (minus backing construction portion 6A);
(e) blister pack 17; and
(f) tamper evident strip 150.
Arrangement 1 can be assembled in a variety of ways, using a variety of methods. The schematic of
In general, according to the principals disclosed above, a method of dispensing a sheet product from a package is provided. The method generally includes steps of: stripping open a receptacle by pealing a hinge cover portion having resealable pressure sensitive adhesive thereon, from a peripheral rim portion of the receptacle; removing a sheet product from the receptacle; and reclosing the receptacle by resealing the hinge cover portion to the peripheral rim portion, i.e., with the pressure sensitive adhesive. In general, the step of stripping is limited by a pair of curved stops; and, the step of stripping involves nonremoval of the hinge cover portion from the package. By this latter, it is meant that the hinge cover portion remains attached to the package and is not removed there from, during the stripping step. By the term “limited” in this context, it is meant that the curved stops will stop or limit stripping, if stripping is conducted until they are reached.
Preferred methods involve, prior to the step of stripping, a step of separating the header portion from the remainder of the package. This step preferably involves leaving a reinforced tab on the package, in order to have a strengthened tab that is nontacky, to grab to facilitate opening. In various applications, prior to the step of separating the header portion from remainder of the package, a tamper evident seal strip, between the header portion and the receptacle, is opened. In still other systems, the strip will be opened during the step of removing the header portion from the package.
The above specification provides a complete description of the manufacture and use of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims.
This application is a continuation of application Ser. No. 10/112,218, filed Mar. 29, 2002 now U.S. Pat. No. 6,726,054, which is incorporated herein by reference.
