Definitions

  • This invention relates to bags for use in storing products such as but not limited to powdered or granular detergent, pet food, coffee, cereal etc., wherein the bag has a line of weakness, which provides for easy opening ofthe bag. More particularly the bags further comprise an adjustable means for re-closing.
  • the need remains for a flexible bag for packaging consumer products that is easy to open i.e. without the aid of a knife, scissors or other utensil.
  • a mechanism by which the bag can be securely re-closed after opening by the consumer should be unaffected by any contamination.
  • the need also remains for a re-closing means that is adjustable to provide a secure and reliable seal as the bag becomes less full.
  • the present invention meets the aforementioned needs by providing an easy to open flexible bag.
  • the bag is further provided with a means for re-closing, which means may also be adjustable.
  • a flexible bag comprising a front panel, back panel and two inwardly folded side panels, each panel having an upper and lower edge, a top portion and a bottom portion which are sealed by joining ofthe front panel to the back panel, the top portion being further defined by a line of weakness, wherein at least a portion of one panel ofthe bag remains un- weakened by the line.
  • the line of weakness allows a clean and controlled rupture ofthe bag.
  • the bag may further comprise a means to re-close the bag after initial opening by the consumer.
  • the re-closeable means may be adjustable to provide an effective and reliable closure as the contents ofthe bag are depleted.

  • Figure 11 is a vertical perspective view of a fourth embodiment ofthe present invention in the closed position.
  • FIG. 1 A particularly preferred bag 10 made in accordance with the present invention is illustrated in Figure 1.
  • the bag 10 is illustrated having front panel 12, back panel 14, and side panels 16 and 18 with each panel having an upper edge 20 and a lower edge 22.
  • the bag 10 also has a top section 24 and a bottom section 26, which are sealed by joining front panel 12 to back panel 14 along upper edges 20 and lower edges 22.
  • the bag 10 is provided with a line of weakness 28, wherein at least a portion of at least one of panels 12 or 14 is not weakened by the line 28. In a preferred embodiment the line 28 spans both side panels 16 and 18 and one of either front panel 12 or back panel 14.
  • Figure 2 illustrates the same bag 10 as Figure 1 wherein the line of weakness 28 has been opened by pulling on either side ofthe line 28.
  • Figure 3 represents the same bag 10 as Figure 1 and additionally comprises re- closeable means 30 (not shown in Figure 3) and 32.
  • Re-closeable means 30 and 32 can be any mechanical fastening mechanism and are preferably comprised of a hook and loop fastening system, wherein one ofthe means 30 or 32 is the hook component and the other is the loop component. It is within the scope of this invention that the two are interchangeable.
  • Figure 4 shows the re-closeable means 30 as a small strip adjacent to upper edge 20 and affixed to front panel 12. It is also within the scope of this invention that the re-closeable means is comprised of a hook and hook system rather than a hook and loop system.

  • One component 30 ofthe re-closeable system is attached with the hook or loop portion facing the panel that is attached to, either front panel 12 or back panel 14. A portion of component 30 is left unattached. Closing ofthe bag occurs by two consecutive folds ofthe top section 2 ofthe bag 10. The first fold leaves the unattached part ofthe re- closeable system sticking out and enables it to match to the second component ofthe system. The second fold actually matches the mechanical fasteners together.
  • Figure 11 represents this alternative embodiment in the closed position. Bag Materials
  • the bags ofthe present invention are formed from elastic materials including but not limited to polymeric film, woven materials, non-woven materials, preferably polyethylene film, more preferably monolayers, coextrusions, two-layer laminations, three- layer laminations and metalized laminations, all materials with or without lacquer coatings. Bags according to the present invention can be formed by any method known in the art. One method for forming flexible bags from a continuous web of material is well known in the art and described in U.S. Pat. No. 5,054,619, issued to Muckenfuhs.
  • the easy opening feature of bags according to the present invention results from the weakening ofthe film material in the desired trajectory of bag rupture or separation.
  • the line of weakness is such that at least a portion of one panel ofthe bag remains un- weakened by the line. This prevents the entire top ofthe bag from being separated upon opening. After opening, the flap that results from the line of weakness being broken provides the bag with a handle or grasp area for the consumer to hold onto while dosing the product. This feature provides better maneuverability ofthe bag and allows easier dosing.
  • the line of weakness will deteriorate the strength ofthe film in such a way that it can withstand normal filling, packing and handling operation and yet be easily opened by the consumer. This behavior is achieved by reducing the trapezoidal tear strength ofthe original film. Reduction ofthe trapezoidal tear strength is also most likely accompanied by loss of tensile strength.
  • the line of weakness is characterized by the following test methods: a)ASTM D- 882 Standard Test Method for Tensile Properties on Thin Plastic Sheeting and b) ASTM D-5733 Standard Test Method for Tearing Strength of Nonwoven Fabrics by the Trapezoidal Procedure.
  • the resultant graphs of these test methods are exemplified in Figures 8 and 9.
  • the samples used to generate Figures 8 and 9 are taken from the line of weakness 28 as shown in Figure 1.
  • the line of weakness 28 must be parallel to the shortest side ofthe sample (i.e.; width).
  • the line of weakness 28 must cover the entire width ofthe sample and must be centered with respect to the sample length.
  • the slot for initiating the cut ofthe trapezoidal tear sample must be on top ofthe line of weakness 28.
  • the line of weakness is characterized by three parameters obtained from the above-mentioned standard tests.
  • the first parameter is yield stress value. Referring to Figure 8, this graph is illustrative ofthe approximate yield stress value of a weakened film (shown in Figure 8 as Y 2 ) versus the approximate yield stress value of an unweakened film (shown in Figure 8 as Y ).
  • the yield stress value ofthe weakened film in the ASTM D-882 tensile test should be no less than 90% ofthe yield stress value ofthe un- weakened film.
  • the final or rupture stress value ofthe weakened film (shown as R 2 in Figure 8) should be no lower than 90% ofthe yield stress value ofthe unweakened film Y,.
  • the average trapezoidal tearing force according to ASTM D-5733, ofthe weakened film should be less than 4Kgf.
  • Figure 9 is illustrative of a typical graph obtained using ASTM D-5733 for measuring trapezoidal tear strength on the weakened film of a single specimen. With regard to both Figures 8 and 9, the values indicated therein for force, elongation ( Figure 8), and extension ( Figure 9), should be considered as merely exemplary and in no way limiting to the present invention.
  • the line of weakness may possess a pattern. Those patterns may take the form of a continuous line, a dashed line, or a combination thereof. However the most preferred pattern is the dashed line, wherein the dashed line is comprised of a plurality of scored segments.
  • the length of each scored segment varies from about 0.12 mm to 4.4 mm, preferably varies from about 0.3 mm to 2 mm, and most preferably varies from about 0.6 mm to 1 mm.
  • the distance between adjacent scored segments varies from about 0.4 mm to 4 mm, preferably varies from about 1 mm to 3 mm, and most preferably varies from about 1.5 mm to 2 mm.
  • the score depth will vary depending upon the thickness ofthe film.
  • a starting notch may be provided at some point along the line of weakness.
  • the starting notch provides an area, which is easier to tear because the scoring is deeper. If the line of weakness spans the back panel wherein there is also a vertical seal, the starting notch provides easy tearing through the multiple plies ofthe vertical seal to the line of weakness.
  • the line of weakness can be produced using methods including but not limited to scoring, perforating, chemical treatment, preferably laser scoring, laser perforation, mechanical scoring, mechanical perforation, embossing methods, or combinations of these methods.
  • the line of weakness is preferably made in the film before it is formed into a bag.
  • One method of making a line of weakness in a flexible film uses at least one laser. First a laser bean with sufficient wattage to evaporate a portion ofthe film material is focused onto the film. The use of laser technology allows for very accurate control ofthe depth or penetration from very slight scoring to complete perforation ofthe film. A laser using any form of electromagnetic radiation can be used. Suitable lasers for use in the present invention include those based on CO 2 gas.
  • the speed ofthe film and the movement ofthe laser beam are dependent upon the pattern and depth of score desired as well as the type of film used.
  • Suitable methods for laser scoring films are disclosed in US Patent Nos. 3,626,143, 3,790,744, 3,909,582 all to American Can Company and US Patent Nos. 5,158,499 and 5,229,180 to American National Can Company, US Patent No. 5,001,325 to LPF Verpakkingen B.V, US Patent No. 4,743,123 to Wavin B. V., Japanese Patents 09133018, 07008283 and 06103200 all to Dainippon Printing Company.
  • Another suitable method for producing the line of weakness is the use of blades.
  • the blades are installed on an engraving cylinder, which is mounted directly on the film processing machinery so that the cuts are made prior to formation ofthe bag.
  • Different blade patterns can be used to get different patterns in the line of weakness.
  • the pressure applied to the blades is also varied during the process to control the dimensions and depth ofthe cuts to ensure the bag opens easily.
  • Embossing is another alternative method for production ofthe line of weakness.
  • the embossing technology weakens the film in specific areas by means of pressure, temperature, time and a deforming profile. The desired results are achieved by changing the caliper and/or material structure at the embossed trajectory.
  • the basic equipment used for embossing consists of a sealing jaw capable of pressing against a back plate. A deforming profile or pattern is fixed to the jaw and heated. The film is pressed between the deforming profile and the back plate.
  • the main variables known to affect this process are: heating temperature, cooling temperature, pressure, heating time, cooling time, film tension while embossing, film tension after embossing, back plate material, back plate thickness, back plate temperature, jaw pattern and jaw thickness.
  • the embossing unit would be installed after an unwinding station of film, preferably incorporated into the packaging equipment line. Suitable examples of embossing are described in US Patent No. 5,878,549 to American National Can Company.
  • the re-closeable system is resistant to contamination by the contents ofthe bag. Its main objective is to protect granule products contained in bags from spillage, humidity, and other external factors that might affect the integrity ofthe product.
  • This re- closeable system comprises a mechanical fastener, preferably hook and loop or hook and hook type, attached to a flexible bag that allows consumers to open and securely close the bags as many times as product uses in the bag.
  • the system consists of placing fastening materials on opposite panels ofthe bag.
  • the panels are the front and the back panel although other configurations are contemplated.
  • the fasteners can be either disposable or industrial materials. It is desired to use disposable materials to optimize costs.
  • the mechanical fasteners can be of any shape and size, and in any disposition.
  • the particular configuration ofthe re-closeable system components should be such that the bag can be sealed throughout the entire use ofthe product contained therein. By sealed is meant that no product spills out when the bag is tipped on its side.
  • the re-closeable system is characterized by the energy required to peel off one component ofthe fastener from the other component. This energy must not be less than 2.4Kgfmm per each Kg of product contained in the bag.
  • the re-closeable system is intended to work with the easy opening feature described above which facilitates the opening ofthe bag.
  • At least one (1) piece ofthe mechanical fastener is placed on one panel ofthe bag while a piece ofthe matching fastener is placed on the opposite panel ofthe bag.
  • Preferably one piece ofthe mechanical fastener is a vertical strip.
  • the top ofthe bag (with the small piece of fastener) is rolled over for the two fasteners to match and tightly close the bag as the product is being consumed. As more product is consumed, the fasteners close farther down vertically to allow the tight seal.
  • a variation of this design is also a button-to-button closure. This means that the mechanical fasteners can also consist of two individual buttons that perform the seal. In this case, the seal is a stationary one, instead of an adjustable one.
  • the adhesive can be either a hot melt or pressure sensitive adhesive.
  • a hot melt adhesive is applied to the mechanical fastener right before the piece is to be applied to the bag.
  • the pressure sensitive adhesive is adhered to the fastener as one piece.
  • the application of these mechanical fasteners to the bag can be accomplished in different ways.
  • One way is to adhere these fasteners to the film before the bag is produced.
  • the pieces of mechanical fasteners are attached to the film either while the roll of film is being prepared or while the roll of film is being unwound at the machine.
  • the mechanical fasteners may also be adhered to the bag after it has been formed.
