Definitions

  • the present invention relates to an improved reclosable, tamper-evident container formed, at least in part, from a flexible material. Access to the interior of such a container is provided by a security seal formed through the flexible material, and the reclosable fastener of this invention is attached to the container in sealing relation to that seal.
  • the improved fastener of this invention is particularly characterized by its structure comprising a pair of mating, reclosable sealing strips, both of which are attached to a common surface of the container's flexible material.
  • the reclosable fastener of this invention is disposed on the inside surface of the container.
  • Reclosable containers utilizing zipper-type fasteners are well known in the packaging industry and are used for holding, displaying and dispensing a wide variety of products ranging from hardware items to food products intended for human consumption.
  • the construction of virtually all such prior art fasteners comprises one or more female parts which releasably receive one or more corresponding male parts.
  • those portions of the fastener bearing the respective female and male parts must typically be attached to opposing sides of the container such that the female and male parts will be in registry with each other.
  • a typical such construction is disclosed in U.S. Pat. No. 4,909,017 to McMahon and Dogr.
  • the present invention relates to an improved tamper-evident container formed from a flexible material and having a reclosable fastener.
  • the fastener of this invention comprises a pair of mating, reclosable sealing strips, each comprising a strip base segment which is attachable to a common surface of the material forming a wall of a reclosable container.
  • Each of the sealing strips further comprise a second segment integral with its corresponding base segment and free from the container wall surface.
  • One of the strips comprises a male fastener part, and the other of the strips comprises a female fastener part in receiving relation to the male part. Tamper-evident access to the interior of the container is provided by a removable portion of the flexible material to form an aperture for access to the reclosable fastener.
  • the male fastener part is at the juncture of one of the base segments and its corresponding second segment, and the female fastener part is formed on the second segment of the other sealing strip.
  • Both base segments are attached to a common interior surface of the flexible material, and both second segments are free from the common surface.
  • the female fastener part is formed on one of the sealing strip second segments, and that second segment is attached to a second surface of the flexible material opposite the common surface.
  • the invention accordingly comprises the features of construction, combination of elements, and arrangement of parts which will be exemplified in the constructions hereinafter set forth, and the scope of the invention will be indicated in the claims.
  • FIG. 1 is a side elevation showing a segment of a first embodiment of the container of this invention with the fastener attached to the inside of a segment of the flexible material at least partially forming a reclosable container.
  • FIG. 2 is a side elevation similar to that of FIG. 1 showing the segment of the reclosable container with the tamper-evident portion removed and the fastener opened.
  • FIG. 3 is a view similar to that of FIG. 1 showing a second embodiment of the container.
  • FIG. 4 is a side elevation similar to that of FIG. 3 showing the segment of the reclosable container with the tamper-evident portion removed and the fastener opened.
  • FIG. 5 is a sectional view taken along line 5 - 5 of FIG. 6 showing attachment of the reclosable fastener to a common interior surface of a reclosable container.
  • FIG. 6 is a plan view of the reclosable container shown in FIG. 5.
  • a first embodiment of the improved tamper-evident container formed from a flexible material and having a reclosable fastener is generally indicated as 10 in the views of FIGS. 1, 2, 5 and 6 .
  • the reclosable fastener is generally indicated as 12 .
  • fastener 12 comprises a pair of mating, reclosable sealing strips, generally indicated as 14 and 16 , respectively.
  • Each of the sealing strips 14 and 16 comprise a base segment 18 and 20 , respectively.
  • Base segment 18 is attached to interior surface 22 of flexible material 24
  • base segment 20 is similarly attached to the common interior surface 22 .
  • attachment of the fastener 12 to common interior surface 22 is indicated by perimeter seal 26 .
  • removable portion 28 of flexible material 24 by which access to the interior of container 10 may be obtained once portion 28 is removed to form an aperture providing access to strips 14 and 16 whereby they may be separated from each other.
  • removable portion 28 is defined by a plurality of cuts formed through flexible material 24 .
  • these cuts comprise a plurality of perforations 30 and at least one slit 32 , though a pair of opposed slits 32 are illustrated in the view of FIG. 6.
  • Slit 32 provides a free segment of flexible material 24 whereby portion 28 may be removed to provide access to fastener 12 .
  • the perforations 30 are preferably formed within the area defined by line A-A, and the slit, or slits, 32 are preferably formed within the area between arrows B.
  • sealing strip 14 further comprises a second segment 34 integrally formed therewith, but not attached to common interior surface 22 .
  • Sealing strip 16 also comprises a second segment 36 integral with its base segment 20 , but not attached to common interior surface 22 .
  • a female fastener part 38 is formed on second segment 34
  • a corresponding male fastener part 40 is formed on sealing strip 16 at the juncture of base segment 20 with second segment 36 .
  • container 10 further includes another segment of flexible material 24 ′ forming another wall thereof, and a seam 42 is provided by the joining of flexible material 24 to a corresponding segment of flexible material 24 ′.
  • a similar seam 42 ′ is formed at the bottom of container 10 .
  • an hermetic seal is a particular advantage of this invention.
  • the perimeter seal 26 extends around the perimeter of fastener 12 .
  • a broadened segment 44 can be seen at each end of perimeter seal 26 .
  • Broadened segment 44 is frequently referred to in the packaging industry as a “splotch” seal.
  • a splotch seal involves the application of heat and pressure to the distal ends of sealing strips 14 and 16 so as to form a flatened, broadened segment 44 .
  • an hermetic seal is formed in completely surrounding relation to the removable portion 28 .
  • second embodiment 10 ′ a second embodiment of the tamper-evident container is generally indicated as 10 ′.
  • container 10 ′ Inasmuch as the structural elements of container 10 ′ are essentially identical to those of first embodiment 10 , identical reference numerals have been used for their identification.
  • second embodiment 10 ′ further comprises a tack seal 46 to bond second segment 34 to inside surface 48 of flexible material 24 ′ forming the opposite side of container 10 ′.
  • tack seal 46 to bond second segment 34 to inside surface 48 of flexible material 24 ′ forming the opposite side of container 10 ′.
  • first and second embodiments of the container 10 and 10 ′ respectively, attention is now invited to the following description of the method for attaching fastener 12 to a flexible material 24 for providing a tamper-evident reclosable opening therethrough.
  • a segment of flexible material 24 is selected for forming a container 10 .
  • a pluality of cuts comprising perforations 30 and at least one slit 32 are made to define a removable portion 28 .
  • a reclosable zipper-type fastener 12 is selected and cut to a predetermined length sufficient to overlie the removable portion 28 .
  • fastener 12 Opposed distal ends of fastener 12 are then “splotched” and the splotched length of fastener is disposed in adjacent, overlying relation to removable portion 28 .
  • the perimeter seal 26 is formed by the application of pressure and heat. If desired, tack seal 46 would be made in a subsequent step. From that point on, the container would be formed and filled using standard form and fill apparatus and methods. No further manipulation of fastener 12 and its related removable portion 28 is required.
