SUBSTANCE: set of invention relates to container for food products. Integrity indicator comprises appliance connected with resealing appliance and appropriate container with film wrap. Note here that appliance generates audible sound in reopening said resealing appliance and comprises, at least, one strip initially attached to resealing closing appliance and appropriate container. In opening resealed closing device for the first time, said strip gets torn to produce audible sound. Package integrity may also be indicated by moving second panel or movable cut lug parts.
EFFECT: reliable indication.
The present invention relates to a resealable closure for packages containing products and, in particular, to such resealable closures that have an integrity indicator of the package.
Some containers intended for food, such as pastries and other snacks, usually include an outer wrap. In one type of container, a wrapper surrounds the frame, which serves as a tray to place the food product and to protect the food product from damage. Other food products come packaged in plastic trays, such as thermoformed trays, which are sealed at the top using a certain type of capping material. One of the latest advances in the field of closures for food containers includes a resealable closure as described in US Pat. No. 6,918,532 (hereinafter referred to as “Patent 532”), incorporated herein by reference, which describes a wrapper that forms the top a container that has an access opening covered by a re-sealed sealing panel.
In the field of packaging, various devices are used to indicate whether the packaging has been opened previously and whether the integrity of the packaging has been compromised; such devices are often referred to in the art as “indicating an unauthorized opening”. For example, one of the last closure means indicating packaging integrity is described in US Patent Application No. 11/500497, hereinafter referred to as' 497 and incorporated herein by reference, which shows closure means consisting of a two-layer material having an inner film layer and an outer film layer forming the top of the container. The outer film layer has a sealing panel covering a portion of the inner film layer, which together with the sealing panel forms an opening. The means indicating the integrity of the package comprises a panel of an inner film layer that is separated from the sealing panel, indicating that the closure has previously been opened.
In the field of packaging production, there is a need to improve integrity indicators for re-sealable closures, preferably suitable for use with a re-sealable closure intended for use with containers or packages containing food products.
The present invention relates generally to a resealable container closure in which the integrity of a package is indicated by a device that breaks and / or produces an audible sound when the resealable closure is opened for the first time.
The present invention, in one embodiment, comprises a means indicating packaging integrity that has a device associated with a resealable closure and a corresponding container having a film wrap. The device preferably produces an audible sound when opening the resealable closure for the first time. The device comprises at least one strip originally attached to the fixed and movable part of the resealable closing means, so that when opening the resealable closing means for the first time, at least one of the bands is torn, preferably producing an audible sound. The stripes may include a weakened area, such as a narrowing at one of the places along their length. The integrity of the package is indicated by a solid strip that can be seen through the opening of the resealable closure and, conversely, a broken or non-integer strip should indicate that the resealable closure has previously been opened.
In another embodiment, the integrity of the package is indicated by a transparent window in the resealable closure, so that the portion that is visible through it before the closure is opened for the first time will not be visible after the closure is opened for the first time and re-sealed. This portion may be one of the strips or may be a second panel that is separated from the strips.
In yet another embodiment, the device comprises at least two bands, wherein at least one strip will break at a different time than the other one or more stripes when opening a resealable closure, while preferably producing at least two separately audible sounds when tearing each strip.
The means for indicating the integrity of the package may include packaging closure having an upper part, an access opening in the upper part and a sealing panel that covers the access opening and tightly interacts with the upper part around the access opening so as to provide initial sealing of the package and then, after it is opened for the first time, to re-seal it on top. Associated with a resealable closure is a device that preferably produces an audible sound when the resealable closure is opened for the first time.
Preferably, this device produces an audible sound before the product contained in the package can be removed.
The present invention, in another embodiment, relates to a package having a closure means indicating the integrity of the package, which comprises a top, a valve formed on the top, and when the valve is separated from the top, an access opening at the top opens, and a sealing panel that covers the valve and access hole and hermetically interacts with the upper part around the access hole so as to initially seal the package and then after it is opened for the first time, be resealed on top, and a device associated with the resealable closing means that produces an audible sound when the resealable closing means is opened for the first time, wherein the device includes at least one strip having portions, attached to both the top and the valve, and when opening the package for the first time, at least one of the strips breaks, indicating that the package has been opened.
The present invention, in another embodiment, relates to a closure indicating the integrity of the package, comprising a film layer forming the top of the container and having a valve defining an opening for accessing the contents of the container and having at least one strip connecting the valve to the remaining part of the top. The sealing panel completely covers the valve, including at least one strip of the film layer. A detachable adhesive placed on the sealing panel or film layer, or both, fastens the sealing panel to the film layer. The sealing panel can peel off from the film layer by pulling the sealing panel in the peeling direction and can be closed again on the upper part to seal the access hole when the sealing panel is moved back to the upper part. When peeling off the sealing panel for the first time, at least one strip connecting the valve to the cap is torn.
The present invention in yet another embodiment relates to a closure indicating integrity of the package, which also contains at least a two-layer material containing an inner layer, adhesive bonded to the outer layer and forming the upper part of the container. The inner layer has a first panel, a second panel and at least one strip connecting the first panel to the rest of the upper part of the container. The outer layer has a sealing panel made therein, which completely covers the first panel, covers the strip and covers the second panel of the inner layer. The first panel and the sealing panel are constantly interconnected in order to obtain an opening for access to the container. A detachable adhesive applied around the perimeter of the sealing panel fastens the sealing panel with the inner layer and the second panel. The sealing panel can peel off from the inner layer and separate from the second panel by pulling the insulating panel in the direction of peeling and can re-close the upper part to seal the holes when the sealing panel is moved back to the upper part. When opening the closing means for the first time, at least one strip is torn between the first panel and the remaining part of the upper part of the container. After closing, the second panel is separated from the sealing panel. Advantageously, in one embodiment, the at least one strip is integrally formed with the inner layer.
The integrity of the package may also be indicated by the mismatch of the openings in the sealing panel with the lobes after opening and re-sealing the sealing panel.
Food products placed in a container may include, but are not limited to, baked goods, crackers, peanuts, cheese, sliced, and semi-liquid foods.
Other features and advantages of the present invention are indicated or apparent from the detailed description of the preferred embodiments of the invention below.

In the figures and, in particular, in figures 1-4, shows the package 10 with a closing means 11, which includes a means indicating the integrity of the package. The package 10 includes a two-layer wrapper comprising a first, inner film layer 12 and a second, outer film layer 13 forming an upper or outer surface 14, side surfaces 16, a lower surface (not shown) and tapered ends 18, 19. The inner film layer 12 and the outer film layer 13 are made of a polymer film or other flexible material that has been cut, rolled, or otherwise pressed to limit an internal cavity or container designed to hold the desired product, such as to food products that must be placed in package 10. Packaging 10 can be used for storage and distribution of food products, such as pastries, crackers, sweets and other products. The outer film layer 13 may include graphic images or other indications indicating the contents of the package 10.
Advantageously, the inner film layer 12 is formed simultaneously with and adheres to the outer film layer 13. During the manufacture of the package 10, a first, inner film layer 12 is incised on its side on a first tear line 20, which includes all dashed lines shown in FIG. 1, except for the second tear line 23. The outer film layer 13 is notched on it the side on the third tear line 23 and notches 25. The inner and outer tear lines are described in the publication of patent application US No. 2005/0276525, incorporated herein by reference.
The first tear-off line 20 is formed as a continuous tear-off line for restricting the first panel 22. The first tear-off line 20 also defines a plurality of strips 50, 52, 54. The second tear-off line 23 forms a second panel 42, which also serves to indicate the integrity of the package.
The first panel 22 can be separated from the rest of the inner film 12 in order to open the opening 24, so that it is possible to access the contents of the package after the strips 50, 52, 54 have been torn (FIGS. 2a, 2b). Each strip 50, 52, 54 is connected as a whole and remains attached to the rest of the inner layer 12, forming the top 14 on the parts 50A, 52a, 54a of the strips, respectively, and part of the strips 50, 52, 54 remains attached as a whole to the first the panel 22 with strip sections 50b, 52b, 54b, respectively. Each strip 50, 52, 54 has a weakened portion formed by narrowing the strip in portions 50c, 52c, 54c, respectively. The narrowed portions 50c, 52c, 54c form a weakened region for the respective strips 50, 52, 54, so that the corresponding strip is torn in the narrowed portions 50c, 52c, 54c when the closing means is first opened.
The strip portions 50b, 52b, 54b are connected integrally with the valve 22 of the first film layer by the strip ends 50d, 52d, 54d, respectively. Advantageously, the notch 20 forms the ends 50d, 52d, 54d of the strips in the form of parallel U-shaped elements, which help to ensure that the strips 50, 52, 54 do not tear near the ends 50d, 52d, 54d of the strips and remain connected as a whole with the first panel 22 and allow the bands 50, 52, 54 to burst in the weakened narrowed portions 50c, 52c, 54c, respectively.
The second panel 42 remains connected as a whole with the inner film layer 12 at the end 44 even after the package is opened and the rest of the second panel 42 falls into the hole 24, as described in more detail in the application '497.
The third tear line 21 limits the sealing panel 26 of the outer film layer 13, and the die cuts 25 limit the plurality of lobes 27 on the sealing panel 26. The sealing panel 26 extends outside the periphery of the first tear line 20 and the second tear line 23 adjacent to the hole 24, so that the sealing the panel 26 completely covers and continues beyond the perimeters of the first panel 22, the strips 50, 52, 54 and the second panel 42. As a result, the sealing panel 26 completely covers the first panel 22, the strips 50, 52, 54 and the second panel 42.
The side of the sealing panel 26, which faces the inner film layer 12, including the flap portions 27, is coated with a releasable adhesive 28 (see FIGS. 2a, 2b), so that the sealing panel 26 can be re-sealed to the inner film layer 12 on a portion adjacent to the first panel 22, and thus the lobed portions 27 remain permanently attached to the inner film layer 12.
Alternatively, or along with the releasable adhesive 28, the releasable adhesive may be applied to the inner film layer 12 along the outer perimeter of the first panel 22. The releasable adhesive may be any pressure sensitive adhesive that allows re-sealing and includes the types of adhesives described in the patent. US application No. 11/029626, incorporated herein by reference, but not limited to. The sealing panel 26 is provided with a tab 30 or other gripping means that is not coated with adhesive 28, so that the sealing panel 26 can be peeled off from the inner film layer 12 in order to open the package 10.
Advantageously, the sealing panel 26 comprises a portion 29 with a transparent window lying on top of the second panel 42 of the inner film layer 12 before the package 10 is opened for the first time, which allows you to visually observe the second panel 42 attached to it before the package 10 is opened for the first time, and observe the absence of a second panel 42 attached to the sealing panel after the package 10 has been opened to indicate the integrity of the package, as described in the '497 application.
As shown in particular in FIGS. 2a, 2b and 3, the package 10 is opened by gripping the tab 30 and pulling the sealing panel 26 back in the peeling direction, as indicated by arrow 33 (FIGS. 2a, 2b). When the sealing panel is peeled off for the first time, the first panel 22 is separated from the rest of the inner film layer 12, including the second panel 42 and sections 50, 52, 54 of strips along the first tear line 20 of the film layer. The strip portions 50a, 52a, 54a remain integral with the rest of the inner film layer 12, and the strip portions 50b, 52b, 54b remain attached together with the first panel 22 (FIG. 3). In addition, the lobed portions 27 are separated from the sealing panel 26 and remain attached to the inner film layer 12 due to the adhesive 28, thus forming holes 32 in the sealing panel 26 (FIGS. 2 and 3).
Initially, when opening the closure means 11, the strip portions 50a, 52a, 54a are separated from the sealing panel 26, while the strip portions 50b, 52b, 54b remain attached to the sealing panel 26, as shown in FIG. 2a. At a certain point, when the sealing panel 26 is peeled off, the strip 52 is preferably first torn in the narrowed portion 52c of the strip, while the stripes 50 and 54 remain intact (Fig. 2a). When bar 52 is broken, an audible sound is produced, such as a click. As shown in FIGS. 2a and 2b, the strips can be spaced apart by a distance that is smaller than the largest content size shown as an example in FIGS. 2a and 2b as baking 58, so in practice, before the strip 52 is broken, the gap between the strips is too small for baking extract 58.
Pulling the insulating panel 26 further in the direction of the arrow 33 further opens the closing means 11, and ultimately the strips 50 and 54 are torn apart in the narrowed portions 50c, 54c. When each band breaks, an audible sound is heard, such as a click. The predominantly narrowed sections 50c, 54c are respectively in the same position on the bands 50, 54, so that the bands 50 and 54 are torn at the same time, thus producing a combined or one audible sound. Since the band 52 is broken before the bands 50, 54, two audible sounds are heard, one when the band 52 is broken and the second when the bands 50 and 54 are simultaneously broken.
The integrity of the package is indicated by the closing means 11 with the help of several new tools built into the closing means 11. The integrity of the package is determined visually by inspecting the intact strips 50, 52, 54 connected as a whole, which are mainly torn after the closing means 11 is open to a degree sufficient to extract the contents, thus indicating the integrity of the package. Further, the integrity of the package is indicated by audible sounds that are produced when the bands are broken, so that an audible sound indicates that the package is opened for the first time.
In addition, the integrity of the package is indicated by a visual indication of the portion 34 of the sealing panel 26, shown in the form of black letters surrounding the word “SEALED” (Sealed), and the portion 36 of the inner film layer 12 covering the portion of the panel 22, shown as having a gray color, which can be seen through the window section 29 before the closing means is opened for the first time (FIG. 1), and the middle section of the word “SEALED” having a gap 46, which gap exists for the reason that the second panel 42, which them ate and remained untouched before the package was opened for the first time, fell inside the package and is not visible in the 46th lumen section. The lumen portion 46 is thus shown to be unshaded after the closure has been opened and re-sealed (FIG. 4).
In addition, since the sealing panel 26 usually does not return exactly to its original position, instead of being slightly offset from its original position, the packaging condition is indicated by the displacement of the openings 32 of the sealing panel relative to the flap portions 25 after the sealing panel has been opened and re-sealed ( figure 4).
The elements shown in FIG. 5, similar to those shown for the embodiment according to FIGS. 1-4, are indicated by reference numerals increased by 100. The package 110 comprises a thermoformed tray 60 forming side walls 116 and ends 61, 62. To the flange 63 of the thermoformed tray 60 hermetically attached two-layer film material, which contains an inner film layer 112 and an outer film layer 113.
Like the package 10, pulling the tab 130 separates the sealing panel 126 from the outer film layer 113 and separates the first panel 122 from the inner film layer 112, strip sections 150, 152, 154 and the second panel 142. After the package 110 is opened for the first time, the strip 150, 152, 154 will tear in the narrowed sections of the bands 150c, 152s, 154c, producing an audible sound at break and giving a visual indication of the package integrity status, confirming that the package was previously opened, as shown in FIG. 5.
Packaging 110 may be used for various food products such as cheese, sliced, and the like. In addition, packaging 110 can be used for semi-liquid products such as pudding and yogurt. Although the package 110 is depicted as having a rectangular shape, the package 110 may be of any shape, including cylindrical and irregular.
The inner and outer film layers 112, 113 may be made of the same material as layers 12, 13, including polypropylene, polyethylene, cellophane, or any other polymeric material suitable for forming a closure of the package.
Shown in Fig.6-8 elements similar to those shown for the embodiment according to Fig.1-4, indicated by reference numbers increased by 200. The sealing panel 226 has a section 229 with a transparent window, which is located on top of the strip 254 of the inner film layer 212 before how the package 210 will be opened for the first time, which allows you to visually observe the strip 254 attached to it before the package 210 is opened for the first time. Like the package 10, pulling the tab 230 separates the sealing panel 226 from the outer film layer 213 and separates the first panel 222 from the inner film layer 212 and strip sections 250, 252 and 254. After the package is opened for the first time, the strips 250, 252, 254 will tear in the narrowed sections of the strips 250s, 252s, 254s, producing an audible sound at break and giving a visual indication of the integrity of the package, confirming that the package was previously opened, as shown in Fig.7. In addition, the integrity of the package is indicated by the absence of strip sections 254 attached to the insulating panel 226 after the package 210 has been opened.
As shown in particular in FIG. 8, the integrity state of the package is indicated by a visual indication of the portion 234 of the sealing panel 226, shown in the form of black letters encircling the word “SEALED” before the closing means 211 is opened for the first time (FIG. .6), and the middle part of the word “SEALED” with a clearance of 246, which gap exists because the strip 254 that was present, remaining intact before the package was opened for the first time, now fell inside the package and was not visible on site 246 pro Veta. The lumen portion 246 is thus shown to be unshaded after the closing means has been opened and closed again (FIG. 8). In addition, like the package 10, the state of package integrity is indicated by a certain offset of the openings of the sealing panel 232 relative to the flap portions 225 after the sealing panel 226 has been opened and re-sealed (Fig. 8), similar to what was done on the package 10. As shown in 9 and 10, according to another embodiment, the package 310 has one strip 352 located in the middle of the opening 324. The package 310 is designed to house one row of food products, such as pastries 358.
As shown in FIGS. 9 and 10, according to another embodiment, the package 310 has one strip 352 located in the middle of the opening 324. The package 310 is designed to hold one row of food products, such as pastries 358.
Tear-off lines 323a and 323b form a pair of integrity indication panels 342a, 342b. When the package 310 is opened for the first time, the panels 342a, 342b remain integrally connected to the inner film layer 312 at the end 344a, 344b, even after the package 310 is opened and the rest of the panels 342a, 342b falls down into the opening 324 as described in more detail in the application '497.
The package 310 includes a sealing panel 326 with a pair of transparent window portions 329a, 329b that lie over the panels 342a, 342b, respectively, of the inner film layer 312 before the package 310 is opened for the first time. Transparent windows 329a, 329b allow you to visually observe the panels 342a, 342b attached to them before the package 310 is opened for the first time, and to observe the absence of sealing panels 342a, 342b attached to the sealing panel 326, after the package 310 is opened , which indicates the state of packaging integrity.
After the package 310 is opened and re-sealed, the integrity of the package is indicated by the absence of panels 342a, 342b attached to the sealing panel 326 in a manner similar to that shown for the second panel 42 in FIG. 10. In addition, like packaging 10, the integrity of packaging 310 can be seen by offsetting holes 332 in the sealing panel relative to the flap portions 325 after the sealing panel 326 is opened and re-sealed (FIG. 11). Additionally, the integrity state of the package is indicated by an audible sound when the strip 352 breaks when the package 310 is opened for the first time.
The present invention shows embodiments with three rows of food products (such as baked goods) with three stripes and with one row of food products (such as baked goods) and one strip. It is clear that the invention can be applied to packages with any number of rows of food products, in which the number of strips is selected as desired, taking into account the number of rows of food products, the width of the package and the desired gap between the strips. In addition, in packages of various sizes, any desired number of windows can be used, regardless of whether these windows are located on top of the second or third panels or on top of one or more strips. In addition, food products may be placed in rows across the packaging or food products may not be placed in rows at all, as peanuts. In any of these embodiments, the present invention may include any suitable number of strips and / or a suitable number of sealed windows. It is assumed that all such options are within the principles of the present invention, the scope of which is determined by the attached claims.
