Description
ZIPPER SLIDER ASSEMBLY WITH A DIAPHRAGM FOR
FLEXIBLE PACKAGES
Field of the invention This invention relates to a zipper slider assembly with a diaphragm for flexible packages.
Background of the invention Existing packages having zipper assemblies suffer from problems such as io not being able to retain aroma and freshness of food and other articles packaged inside them during transportation and storage. Hence, by the time the contents of the package reach the end user they are insipid.
Furthermore, said zipper slider assemblies do not provide any tamper-proof features for informing the end user whether the package has been opened previously or not.
US patents 5,435,864 and 5,425,825 disclose plastic bag having a reclosable plastic zipper and non-reclosable peel seal. In US patent 5,435,864, the peel seal is formed by co-extruding an adhesive onto a side strip adjacent to the interlocking zipper while, in US patent 5,425,825 the seal is formed by applying adhesive to the side strip. Further, the barrier provided by a peel seal is permeable and is not strong enough for preventing undesired aroma, microorganisms, and moisture from entering into packages containing food items, thereby making the packaged items vulnerable to fast deterioration.
It is known in some applications to use a flexible reclosable package having a reclosable zipper construction openable and closable by a slider device, and a primary tamper evident structure disposed over the zipper for indicating whether access has been gained to the interior of the package. The package also has a second tamper evident structure consisting of a polymeric film or a peel seal, which is permeable. As a result, the structure has very limited barrier properties to s prevent undesired aroma, microorganisms, and moisture from the atmosphere from entering the package. At the same time, the structure is not capable of retaining inside the package the desired aroma, microbe free air and gases like nitrogen that are filed in the package containing food items for keeping them fresh.
The further disadvantage of the above US patents 5,435,864 & 5,425,825 and some other known reclosable packages using a polymeric film extruded together with the zipper profile for providing tamper evident structure is that it limits the choice of material in case a structure having special properties such as capable of being holographed or printed is required for the package.
Objects and summary of the invention The object of this invention is to maintain the desired aroma and freshness of food and other articles packaged inside a flexible package during transportation and storage till the time they reach the end user.
Another object of this invention is to provide a tamper proof zipper slider assembly for a flexible package.
To achieve the said objectives, this invention provides a slider zipper assembly with a diaphragm for flexible packages comprising:
- zipper profile consisting of male element and a female element, - said profile having flaps on single side, - said male element having at least a pair of notches, which are coupled to corresponding notches on female elements, - a slider to close said zipper profile characterized in that a diaphragm of at least one metalized laminated film is sealed betureen said flaps to seal and make the package tamper proof and act as a barrier.
The metalized laminated film is holographed, printed or plain.
The sealing of the film to the flaps is carried out by ultrasonic or heat sealing device.
The said zipper profile and slider are made of plastic.
The said flexible package is a pouch.
The flexible package is a stand up pouch with a base.
One wall of the said pouch is sealed on three sides and open towards the zipper assembly.
The said wall is sealed to one of the flaps of the zipper assembly after filling the pouch with desired material.
The said flap has plurality of horizontal lines for the purpose of selective heat transfer and enabling one side sealing on zipper assembly, thereby preventing the zipper from sealing from inside after the pouch is filled with desired material.
Brief Description of the Drawings The invention will now be described with reference to the accompanying drawings.
s Figure 1 shows a slider zipper assembly with a diaphragm / laminate provided on the flaps of said profile, according to this invention.
Figure 2 shows the package with a slider zipper assembly according to to this invention.
Figure 3 shows the second embodiment of the flexible package.
Figure 4 shows the cross-sectional view of the second embodiment of the 15 flexible package.
Detailed description of the preferred embodiments Referring to the drawings, Figure 1 shows the slider zipper assembly consisting of male member 20 having interlocking element 22 and flap 20 24. A female member 26 having interlocking element 28, a flap 30 and rectangular shaped protrusion 32 extending from said flap 30. A slider 34 is shown in the figure for closing and opening the zipper profile. A
diaphragm 36 is sealed between flaps 24, 26 by ultrasonic or heat sealing device.
The diaphragm 36 is a metalized laminate film for providing strong barrier properties that does not allow undesired aroma, moisture and the like in the atmosphere to enter inside the package through it thereby, protecting the packed contents from deterioration. At the same time, aroma of the packed articles, microorganism free air, and packaging gases like nitrogen are retained by the diaphragm 36 inside the package.
Therefore, the diaphragm 36 helps in maintaining the desired aroma and freshness of the food article even during transportation and storage. In addition, when the slider zipper assembly with diaphragm 36 is applied to flexible packages, it makes the package tamper proof. The said flexible packages can be used for carrying pharmaceuticals, stationary, tea leaves, coffee powder and other miscellaneous articles also.
io The constituent films of the laminate can be chosen to provide desired properties as desired in different kind of packages, e.g. the diaphragm 36 can be holographed for identifying the manufacturer and authenticating a genuine product where necessary. The metalized laminated film may be made from multi-layers of films, one of which may be a metal layer, such as an aluminum foil.
The zipper assembly and slider are made of plastic.
In Figure 2, a slider assembly with a package 38, diaphragm 36, a slider 34 and zipper assembly 40 is shown. The slider 34 and zipper assembly 40 are made of plastic.
Figure 3 shows another embodiment of the present invention wherein the flexible package is a standup pouch 44 according to the present invention having a slider 34, zipper assembly 40 and a diaphragm 36.
The bottom 42 of the pouch 44 is such that the pouch stands upright after it is filled with contents. One wall 46 of said pouch 44 is sealed with zipper assembly 40.
However the other wall 48 of the pouch is left unsealed for allowing the contents to be filled inside the pouch 44. After the pouch has been filled, the other wall 48 also is sealed to one of the flaps 24 of the zipper assembly. The said flap 24 has a plurality of horizontal lines 50 for the purpose of selective heat transfer and enabling one side sealing on zipper assembly, thereby preventing the zipper from sealing from inside after the pouch is filled.
The diaphragm 36 is a metalized laminate film for providing strong barrier properties that does not allow undesired aroma, moisture and the like in the atmosphere to enter inside the pouch through it thereby, io protecting the packed contents from deterioration: At the same time, aroma of the packed articles, microorganism free air, and packaging gases like nitrogen are retainded by the diaphragm 36 inside the pouch.
Therefore, the diaphragm 36 helps in maintaining the desired aroma and freshness of the food article even during transportation and storage. In addition, the slider zipper assembly with diaphragm 36 makes the pouch tamper proof. The said pouches can be used for carrying pharmaceuticals, stationary, tea leaves, coffee powder and other miscellaneous articles also.
zo The constituent films of the laminate can be chosen to provide desired properties as desired in different kind of packages, e.g. the diaphragm 36 can be holographed for identifying the manufacturer and authenticating a genuine product where necessary.
Figure 4 shows the cross sectional view of the zipper assembly wherein the male element 20 and the female element 26 of the zipper assembly are shown along with the diaphragm 36. The flaps 24, 30 have plurality of horizontal lines 50 for the purpose of selective heat transfer for one side sealing of the wall.
For clarity, slider 34 shown in Figure 3 is not included in Figure 4.
Additionally, Figure 4 shows more clearly one wall of pouch 44, namely wa1148, still umaled so that contents for the pouch may be filled.
After the pouch is filled, wa1148 is sealed. At the site of use, a user may gain access to the interior of the pouch by breaking diaphragm 36, for example, by tearing, piercing or cutting.
Various embodiments of the invention have now been descxibed in detail. Those skilled in the art will appreciate that numerous modifications, adaptations and variations may be made to the embodiments without departing from the scope of the invention.
Since changes in and or additions to the above-described embodiments may be made without departing from the nature, spirit or scope of the invention, the invention is not to be limited to those details but only by the appended claima.
