This application is a partial continuation of the patent application in process and of shared ownership US 11 / 742,754, entitled Ingredient Package and Method and filed on May 1, 2007, the content of which is incorporated herein Memory as reference.

Technical field

This invention relates generally to containers and, more particularly, to easy-opening food containers. Background

Various types and methods of packaging are known in the state of the art. Aspects that must be taken into account in commercial packaging include the protection of the contents of the package and a use of the package that allows a consumer or user to access the contents of the package. In the case of packaged foods, for example, foods are usually sealed in a container to optimize their shelf life. When a consumer purchases the product, they must open the package to access the items stored in it. However, access to the elements through a sealed container may sometimes require excessive effort to open the container.

In some containers, such as tubular containers, it is also advantageous to easily and completely remove one end of the container to allow the contents to be completely poured out. For example, if it is intended that the contents of a container be poured into a solution for mixing, as in a flavored beverage product, the package must be sealed to protect the contents from outside moisture, but also easily opened by a consumer. These packages are usually made in a vertical forming, filling and sealing process, where a web material is folded and sealed. This sealed material is cut and sealed at one end and then filled with the contents of the container. Then, the second end is also cut and sealed, thus sealing the contents of the container inside. To open the container, a user must pull and separate the gasket or otherwise cut or tear the container.

Several features have been added to this type of packaging to help consumers open it. According to one technique, the side of the package is cut to provide the consumer with a starting point to open the container by tearing it. This technique, however, requires that the container be seated around the cutting portion, which requires additional resources and manufacturing efforts. According to another known technique, the lateral edge of the container is reduced by a physical microabrasion process, which weakens the side of the container in such a way that the package is more easily broken at the edge when a user applies a tearing force to open the container . According to this technique and the prior cutting technique, however, the container will only tear along the weak areas normally present in the container material, so it may be that the tear does not spread straight through the container. On the other hand, tearing is usually stopped at the joint that extends along the package if the user does not apply excessive additional force.

Another known method of helping to open a package includes weakening the material of the package along a given line, so that tearing along that line can be propagated when the package is opened. One of these methods includes cutting the packaging material with a laser. The laser deteriorates the packaging material along a line through the material and cuts it through it. Therefore, when a user tears the container, it will be more likely that the container will tear along the damaged portion with the laser. However, when the entire package is laser-marked, it is usually so weakened that it cannot remain intact during its manufacturing process or during normal handling by a user before opening the package.

The method of laser marking a design on a packaging material to provide additional resistance to a package that must carry a load, such as a ground bag or a relatively heavy similar material, is known. The above descriptions show a relationship of approximately one to two between the length of the marked and unmarked material along a tear line for this type of application; that is, the laser will mark a line approximately half the length of the intermediate unmarked material between each marked portion. If the amount of unmarked portions is increased with respect to the marked portions, a greater resistance of the material is obtained for said cargo bags, but for smaller containers for food products this laser marking ratio will not normally be able to carry a tear line. straight, clean and uniform, through a container, nor will it guarantee that the laser marking is present on the package and the edges of the joint to make tearing and propagation of the tear through the container seal easier .

rows of grooves that extend linearly and are separated laterally, formed in one of their layers, extending parallel and adjacent to the inside of a lateral edge.

US-2005/123724 describes a process for the production of at least one line marked on at least one plastic outer layer of a film. This can be achieved using a device that includes a support surface for the film and at least one projection to form the marking line by the penetration of the projection into the plastic layer when the film is placed against the surface of said surface of said film. support for. The projections can be arranged in the form of ribs on one or more coaxial rollers. The projections can form the marking line by controlling the flow of plastic by ultrasound, compressing the film between a sonotrode and the rollers.

WO03 / 022691 describes a system and method for producing a partially perforated tear line on a substrate material using a high energy beam to cut the substrate material to a depth less than the total depth of the substrate. Varying the level of output energy of the high energy beam during different time intervals weakens a substrate material to provide an easy opening mechanism without significantly reducing the tensile strength of the substrate material. The ratio of the uncut substrate material to the partially perforated can be practically any.

Detailed description of preferred embodiments

In general terms, by virtue of these different embodiments, a container formed through a vertical forming, filling and sealing process includes a web material with sealed end portions to create a vertical tube. The web material also includes a first sealed end and a second sealed end at either end of the vertical tube to create a sealed container. The package includes a laser-shaped cutting design that extends through the web material with cut portions that are approximately one millimeter to approximately three millimeters in length, separated by uncut portions of approximately 0.25 millimeters to approximately 0, 75 millimeters long. The container typically has a vertical length of about 75 millimeters to about 200 millimeters.

Configured in this way, the package provides a sealed container that a user can open along the cutting design of the package. The package may contain food products, such as beverage powders, dessert powders, snack nuts, condiments and dressings that are poured into another container or directly into the consumer's mouth. The laser cutting design, which has a discontinuous marking length of about one millimeter to about three millimeters and a gap between the marks of about 0.25 millimeters to about 0.75 millimeters, gives the web material greater resistance to the traction in order to prevent it from breaking during the conventional vertical forming, filling and sealing process, although it also provides a high probability that an outer edge of the package includes a cut portion to provide a user with an easy start zone of the torn to open the container. Also, this design provides a high probability that an edge of the vertical joint has a cut portion, so that the tearing of the container is more easily propagated through the joint. In addition, the short spaces between the cut portions increase the likelihood of the tearing propagating in a line along the cutting design throughout the package, so that the end of the container is completely removed and relatively easily to allow Unrestricted access to the contents of the package.

That is, a longer or continuous dashed line for the cutting design will excessively weaken the web material and a shorter broken line will make it more difficult to open the web material. A longer space between the cut portions will probably allow the tear to deviate from the marking line and a shorter space between the cut portions will reduce the tensile strength to mimic a continuous mark. As such, a discontinuous design according to the teachings of this description provides a preferred combination of features for this type of packaging.

These and other advantages may become more evident when conducting a thorough review and study of the following detailed description. Referring now to the drawings, and in particular to Figs. 1 and 2, an illustrative package that is compatible with many of these teachings will be presented below. A package 10 formed by a vertical forming, filling and sealing process includes a web material 12 with a first edge part 14 and a second edge part 16 opposite the first edge part 14, which are sealed in a joint 18 The package 10 includes a first sealed end 20 at a first end 22 of the gasket 16 and a second sealed end 24 at a second end of the gasket 16. Any of the gaskets described above can be made by conventional methods including, by For example, the application of heat and pressure to create a laminated joint. With these joints, the contents of the package 10 are protected from external elements, such as moisture and / or oxygen, which may affect the quality of the contents.

The first sealed end 20 and the second sealed end 24 form a first lateral edge 28 of the container and a second lateral edge 30 of the container, wherein the first lateral edge 28 of the container and the second lateral edge 30 of the container are folded web material and created by the edges of the sealed ends 20 and 24, and between them. The folded web material may be grooved along the folding lines 15 and 17 to better define the lateral edges for the user, or it can be configured in the form of rounded portions of the web material, transitioned from the front of the container 10 to the back.

While referring to Figs. 1,2 and 3, the package 10 also includes a cutting design 32 that extends through the web material 12 between the first edge part 14 and the second edge part 16. The cutting design 32 includes a series of cut portions 34 of approximately one millimeter to approximately three millimeters in length (indicated, for example, by line 35 in Fig. 6), separated by uncut portions 36 of approximately 0.25 approximately 0.75 millimeters in length (indicated, for example, by line 37 in Fig. 6), so that the cutting design defines a tearing line 39 through the container 10.

With such a cutting design, the container 10 is practically torn along the tearing line 39 and through the joint 18 without deviating from the tearing line 39 when a user applies a separation force on the first edge side 28 of the container or the second side edge 30 of the container, as shown in Figs. 3 and 4. The range of lengths of the cutting portions and lengths of the uncut portions taught herein also increases the likelihood that the first side edge 28 of the container, the second side edge 30 of the container and an edge 29 of the gasket 18 has cut portions 34, thereby improving the ease with which the container 10 begins to tear and continues to tear through the gasket 18 without a substantial increase in the tear force applied by the user. With this configuration, the user can more easily remove the end of the package completely to release the contents 11 of the package, as shown in Fig. 5. In addition, the web material 12 maintains sufficient tensile strength thanks to the portions 36 not cut to practically withstand the vertical forming, filling and sealing process without breaking.

The web material 12 and the cutting designs 32 are treated in greater detail with reference to Figs. 6 to 9. The web material 12 includes at least two layers. A multi-layer web material 12 includes at least one outer layer 40 comprising at least one of a group that includes PET (ethylene polyterephthalate) and OPP (oriented polypropylene film). The outer layer 40 normally includes information about the product and the brand. A second layer 42 includes at least one of a group comprising PET, OPP and aluminum foil, which typically includes sealant for a two layer structure. An optional third layer 44 can function as a sealant layer, typically comprising mainly PE (polyethylene) or other suitable material for

come into contact with the contents 11 of the package and provide suitable sealing characteristics, such as those generally known in the art, with the second layer acting as a barrier. A layer or more may also be metallized to increase the protection of the contents 11 of the package.

Typically, the cut portions 34 are formed with carbon dioxide lasers during the manufacture of the web material 12 and before the vertical forming, filling and sealing process, although the cut portions 34 can be formed during the forming process, vertical filling and sealing. Other types of lasers can be used to create the cut portions 34.

In a typical technique for laser training, as shown in Figs. 7 and 9, the cut portions 34 have a depth less than the thickness of an outer layer 40 of the container 10. This depth maintains the integrity of the gasket of the container and the strength of the web material 12. Although the cutting design 32 is generally shown as a uniform design herein, the cutting design 32 may have a non-uniform design 50 within the length ranges of the cut and uncut portions taught herein. memory.

According to another technique, a second cutting design 48 can be arranged on one side 46 of the web material in an opposite manner and practically aligned with the first cutting design 32. Additionally, several techniques for laser marking placement are possible, including, for example, a single cutting design on an external part of the package 10, a single cutting design on an internal part of the package 10, cutting designs individually and practically aligned with each other on outer and inner parts of the package 10, double cutting designs on inner and / or outer parts of the container, and so on.

Referring now to Figs. 10 to 13, the joint 18 of the first edge part 14 with the second edge part 16 of the web material 12 may include any type of joint known in the art, but will typically comprise a fin type 52 joint or a flap gasket 62. Joints of this type are known in the art. However, they will be briefly described for clarity. Referring to Figs. 10 and 11, a flap type seal 52 is formed by folding the web material 12 in such a way that the inner portions 46 of the first edge part 14 and the second edge part 16 come into contact. These edge portions are sealed and folded with respect to the container 10, thus creating a "fin." When the cutting design 32 extends through all the web material 12, the cutting design 32 creates a line of weakness through the fin-type joint 52, causing the joint to tear more easily. When the cutting design 32 is configured according to the teachings of this description, it is more likely that a cut portion 34 will be placed over an edge 29 of the fin-type joint 52 to help the tear continue to propagate through the joint 52

Referring to Figs. 12 and 13, a flap gasket 62 is formed by folding the web material 12 in such a way that any one part of the first edge part 14 or the second edge part 16 overlaps the other. Fig. 12, for example, shows the first overlapping edge part 14 on the second edge part 16. Then, these edge parts are sealed, thus eliminating the need for a folded part, such as the fin-type joint 52. When the cutting design 32 extends through all the web material 12, the cutting design 32 creates a line of weakness through the flap gasket 62, making the gasket tear more easily. When the cutting design 32 is configured according to the teachings of this description, it is more likely that a cut portion 34 will be placed on an edge 29 of the fin-type joint 62 to help the tear continue to propagate through the joint 62

According to another technique and referring to Figs. 14 and 15, a package 100 may include two sealed web materials 102 and 104 to define an interior space 105. According to one method, the first web material 102 is sealed to the second web material 104 by a first side edge 114 at along a first side edge seal 128 and a second side edge 116 along a second side edge seal 130. The package 100 also includes a first sealed end 120 and a second sealed end 124 that seal the package 100 between the first side edge seal 128 and the second side edge seal 130. A cutting design 32 as described above extends through at least the first web material 102 in a band between the first side edge 114 and the second side edge 116, so that the cutting design 32 defines a line 39 of torn through the container 100. With this configuration, the first side edge gasket 114 and the second side edge gasket 116 have a high probability of having cut portions 34 while the container 100 is practically torn along line 39 of tearing and through the first side edge seal 128 and the second side edge seal 130 when a user applies a separation force on the first side edge 114 or the second side edge 116. The band materials 102 and 104 also they maintain sufficient tensile strength to practically withstand the vertical forming, filling and sealing process without breaking.

It is possible to have a second cutting design 132 that extends through the second web material 104, between the first side edge 114 and the second side edge 116, practically in line with the cutting design 32 of the first web material 102. Other configurations of cutting designs are supported and are considered within the scope of this description.

Referring to Fig. 16, a method for manufacturing a container 10 according to the teachings of this description is described. The method includes laser marking a cutting design 32 through a web material 12 between a first edge part 14 and a second edge part 16 of the web material 12 and (as indicated

generally by reference number 210) feeding the web material 12 into a device 200 to perform the vertical forming, filling and sealing process. As shown in Fig. 16, the cutting design 32 was laser-framed in the manufacturing phase of the web material 12 and before being fed into the device 200 to perform the vertical forming, filling and sealing process. According to another technique, lasers can be incorporated in the device 200 to perform the vertical forming, filling and sealing process, so that the cutting design 32 can be added after feeding the web material 12 into the device 200 to perform the vertical forming, filling and sealing process. According to another technique, laser marking can cut the web material 12 on two sides of the web material 12 and practically in line with the cutting designs of either side of the material. Then, the web material 12 is sealed along a vertical direction to form at least one gasket 18 and the device 200 is advanced to perform the vertical forming, filling and sealing process. Then, the web material 12 is sealed and cut horizontally through at least one gasket 18 by a first end 22 of the container 10. Then, the web material 12 is cut by a second end 26 of the container 10, with the cutting design 32 located between the first end 22 and the second end 26. Typically, the second cut divides the material 12 into a band so that the length of the first end 22 to the second end 26 is approximately 75 millimeters to approximately 200 millimeters

Although the device 200 for carrying out the vertical forming, filling and sealing process shown in Fig. 16 is designed to create a flap-type gasket, the method described above can be applied to any of the other gasket seals described in the present specification, including, for example, flap gaskets for a package or a container with double band material. For example, the step of sealing the web material along the vertical direction to form a joint may include sealing the web material 12 to a second web material. In this example, two vertical joints can be created at the vertical edges of the web materials. Similarly, the second web material can be laser marked with a second cutting design. Those skilled in the art will recognize other variations in the design of laser marking.

With this configuration, the package created by such a method, and as described herein, provides a relatively easy opening of the package compared to the previous methods that have been provided to help consumers open relatively small packages. made of a band material. In addition, the tear spreads more reliably along the tear line and more easily through the vertical joints of the container. For example, a test was performed to compare the tearing forces that needed to be applied in the time in which a tear propagates along a typical container with a flap-type gasket. The test was performed as follows. Tape-shaped extensions were incorporated into a container with a laser marking design to mimic the turning movement of a user's wrist. The portion of the container located below the marking line was firmly fixed on the test device, while the tape of the extensions fixed to the portion that was on the marking line was secured by means of the jaws of the test device. torn. The test device was a Vinatoru device to test the strength of the joint. The jaws of the test device pulled the tape from the opposite side of the container and moved through the top of the container and upward at a 30 degree angle. The jaws of the test device were equipped with a force transducer and the instantaneous force was recorded at regular intervals.

Fig. 17 shows the test results. The discontinuous cutting design formed with laser as described herein (indicated as "discontinuous") allows the package to be opened with practically the same force or the same ease of opening as if the web material had a marking line with continuous laser (indicated as “continuous”). Both packages marked with laser required a practically smaller opening force than the notch technique (indicated as "notched edge / fin") and the microabrasion technique (indicated as "Fancy cut" by the FANCY CUT packaging brand).

However, as shown in the table in Fig. 18, the discontinuous cutting design has a consistently improved tensile strength in containers with a continuous marking line. The data presented in Fig. 18 were collected by measuring the tensile strength of the containers by means of an Instron test device. The data shows that the cutting design has a tensile strength in a marking line sufficiently improved to present a lower probability of breaking in a vertical forming, filling and sealing process, while requiring approximately the same force opening, as shown in Fig. 17.

Those skilled in the art will recognize that a wide variety of modifications, alterations and combinations can be carried out with respect to the embodiments described above, without thereby abandoning the scope of the claims. For example, many of the illustrative embodiments set forth herein refer to containers of generally rectangular shape, with distinct prominent edges. Other configurations are also possible, such as oval or round containers. Likewise, any variation of multiple marking lines can be provided to provide multiple tearing lines in a container. These modifications, alterations and combinations should be considered as included in the scope of the inventive concept.
