Definitions

  • the invention relates generally to small, flexible containers having sealing devices which may be resealed after having been opened, such as are frequently used for containing plural articles intended to be sequentially extracted from the container and requiring continuous protection prior to their use, e.g. paper tissues, moist towelettes, and the like.
  • container in which the contents of the container are protected by a trouble-free reusable seal, so that such, contents, for example, paper tissues, moist towelettes, and the like, can be extracted one at a time from the container upon opening of the seal and so that after the seal has been reclosed the remaining contents of the container will be protected as before.
  • One basic form of container of this type which is well known, is made of a rectangular sheet of thin foil or plastics material having two side regions folded over toward one another so as to overlap slightly.
  • the overlapped margins of the folded- over side regions of the sheet are heat-sealed to each other to provide a longitudinal seam at the middle of one side (the rear side) of the container, and at each end of the sheet the margins of the folded-over side regions are heat-sealed to the adjacent end margin of the unfolded portion of the sheet that defines the other side (the front side) of the container.
  • the container In its front side the container has an opening through which the contents of the container can be extracted.
  • the opening is normally covered and closed by a flap, preferably made of the same or a similar material as the container body, which is permanently secured at one end to the outer surface of the portion of the sheet defining the front side of the container and has its sheet-engaging face coated with a suitable non-hardening pressure-sensitive adhesive.
  • a separate non- adhesive member which is smaller than the flap but-either of the same shape and size as the opening or of generally the same shape as but somewhat larger than the opening, is adhered to the coated face of the flap in a position such that when the flap is closed. the said non-adhesive member overlies the entire expanse of the opening. Representa ⁇ tive constructions of such a container are shown in U.S. Patent No. 4,420,080. . Disclosure of the Invention
  • a primary problem which has arisen with the aforesaid knpwn containers is that the end region * of the closure flap which is secured to the front side of the container may be torn from the latter when the flap is pulled up to open the container.
  • a secondary problem which has arisen is that, by virtue of the frequent flexing of the flap during opening and closing of the container, the non-adhesive member may shift its position on the flap or even become separated therefrom and thus fail to properly and fully overlie the opening in the front side of the container when the flap is closed.
  • a container which has a front side including an opening to provide access to the contents of the container and a resealable sealing device for the opening
  • the sealing device includes a closure flap which is larger . than the opening and is secured to the front side of the container at one end region of the flap adjacent one portion of the periphery of the opening for hinging ove- ent about a line of attachment so as to be able to overlie the opening, with the face of the flap which is engageable with the front side of the container being coated with a pressure-sensitive adhesive
  • the sealing device further includes a non-adhesive member which is smaller than the flap but at least of the same shape and size as the opening, with the non-adhesive member being adhesively secured to the coated face of the flap in a position thereon where the member will completely overlie the opening when the flap is adhered to the front side of the container;
  • the flap has a pair of opposing, generally L
  • a container of the mentioned class which is further characterized in that the non-adhesive member is die-cut in a peninsular form directly out of the front side of the container so as to have a main. body portion defining the opening and a tongue portion extending generally longitudinally from the main body portion and having opposite side edges generally parallel to the second portions of the L-shaped cuts and terminating at the uncut end of the tongue portion remote from the main body portion of the non-adhesive member, with the said uncut end of the tongue portion lying on a second line of attachment substantially coinciding with the first- mentioned line of attachment of the flap, and in that the non-adhesive member has a second pair of tear prevention holes formed in the front side of the container and located on the second line of attachment each at the termination of a respective one of the side edges of -the tongue portion of the non-adhesive member, whereby tearing of the latter and the front side of the container beyond the second line of attachment is effectively inhibited
  • Fig. 1 is a perspective view of a container according to the invention, with the container being shown in a closed position.
  • Fig. 2 is a similar view but with the container being shown in an open position.
  • Fig. 3 is a top view of the container blank or starting sheet, shown after the die-cutting of the sheet but before the folding thereof and with the sealing flap shown superimposed in dotted lines.
  • Fig. 4 is an enlarged top view of the sealing flap per se. Best Mode for Carrying Out the Invention
  • Figs. 1 and 2 show a container (similar to that illustrated in the aforesaid U.S. Patent No. 4,420,080) in the form of a flexible pouch 10 having on each side an accordion fold 12 (to allow for expansion of the pouch upon insertion of its contents and contraction of the pouch upon withdrawal of its contents) and having on its front side a sealing device 14 including a flap 16 which covers and uncovers an opening 18 through which access may be had to the contents of the container.
  • a container similar to that illustrated in the aforesaid U.S. Patent No. 4,420,080
  • a sealing device 14 including a flap 16 which covers and uncovers an opening 18 through which access may be had to the contents of the container.
  • the flap has its face which is engageable with the front side of the container coated with a layer 28 of pressure- sensitive adhesive, and a non-adhesive member 24, which is smaller than the flap 16 and either is of the same shape and size as the opening 18 or is somewhat larger in shape and size than the opening, is adhesively secured to that face of the flap in a position thereon such that when the flap is closed as in Fig. 1 the member 24 also overlies the opening 18 and prevents the adhesive on the flap from coming into contact with the container contents, e.g. tissues, towelettes, and the like.
  • a non-adhesive member 24 which is smaller than the flap 16 and either is of the same shape and size as the opening 18 or is somewhat larger in shape and size than the opening, is adhesively secured to that face of the flap in a position thereon such that when the flap is closed as in Fig. 1 the member 24 also overlies the opening 18 and prevents the adhesive on the flap from coming into contact with the container contents, e.g. tissues, towelettes, and the like
  • the flap 16 further has an end region 16a by whic it is permanently secured to the front side of the container and at its opposite end has a finger grip 22 which allows the user to lift the flap in order to open the container, with the main body of the flap hinging relative to the end region 16a about a line of attachment (not shown) .
  • tearing of the flap 16 beyond the line of attachment upon opening of the sealing device 14 is prevented by the provision of a pair of generally L-shaped cuts 19a/19b and an associated pair of tear prevention holes 20 in the flap 16.
  • Each cut (see also Fig. 4) has a first portion 19a starting at a respective side edge of the main body of the flap and extending transversely inwardly of the flap intermediate the ends of the latter, and a second portion 19b continuing from the innermost end of the respective first portion 19a and extending generally longitudinally of the flap toward and terminating at the line of attachment.
  • the tear prevention holes 20 are formed on the line of attachment and at the terminations of their associated portions 19b of the L-shaped cuts.
  • the transverse spacing between the longitudinal cut portions 19b is somewhat greater than the width of any portion of the non-adhesive member 24 that is located between those portions of the cuts.
  • the flap 16 has a pair of generally longitudinally extend ⁇ ing tabs or fingers 16b defined at the remote sides of the second portions 19b of the cuts, which tabs or fingers are integral enlargements of the end region 16a of the flap.
  • the tabs or fingers 16b serve to enhance the ability of the end region 16a to anchor the flap 16 to the front side of the container 10.
  • the non-adhesive member 24 of the sealing device 14 may be, although it is not so illustrated in the drawing, a separate member of insular form and having a shape and size which correspond to and are at least the same as the shape and size of the access opening 18, generally as shown in the aforementioned U.S. Patent No. 4,420,080. 'Such an insular member may, of course, be die-cut directly out of the part of the sheet of which the front side of the container is constituted.
  • the non-adhesive member 24 is formed by being die-cut in a peninsular form directly out of the part of the sheet of which the front side of the container 10 is constituted, such that the member 24 has a main body portion 24a and a somewhat narrower tongue portion 24b, the latter extending generally longitudinally from the former and having opposite side edges generally parallel to the second portions 19b of the L-shaped cuts and terminating at the uncut end of the tongue portion 24b remote from the main body portion 24a.
  • the said uncut end of the tongue portion is located at a second line of attachment on the front side of the container which directly underlies and essentially coincides with the previously mentioned line of attachment of the flap 16, and tearing of the member 24 beyond the second line of attachment is prevented by the provision of a second pair of tear prevention holes 26 in the front side of the container on the second line of attachment and at the terminations of the opposite side edges of the tongue portion 24b of the member 24.
  • the member 24 is adhesively secured to the coated face of the flap 16 for joint movement therewith when the flap is moved from its closed position (Fig. 1) to its open position (Fig. 2) .
  • the two sets of tear prevention holes 20 and 26 at the coinciding lines of attachment between, on the one hand, the two portions of the flap 16 and between, on the other hand, the tongue portion 24b of the member 24 and the front side of the container 10 serve to relieve stresses at those lines, thereby inhibiting tearing of either the flap or the non- adhesive member beyond the respective line of attachment.
  • a container 10 of the type shown in Figs. 1 and 2 use is made, as shown in Fig. 3,. of a blank 30 of thin flexible sheet material, e.g. paper, plastic, foil or the like, which is cut into a rectangular shape.
  • Accordion folds 12 are formed in the blank, and a peninsular die-cut is made to form simulta- neously both the outline of an access opening having a wider main portion and a narrower end portion in the portion of the blank between the accordion folds and a non-adhesive member 24 of corresponding shape which is attached to the blank at the uncut end of the tongue portion 24b of the member remote from the main body por ⁇ tion 24a thereof.
  • two inner flap tear prevention holes 26 are die cut into blank 30.
  • a resealable sealing device 14 is formed by attaching a closure flap 16, the structure of which is as shown in Fig. 4, to the front side of the container in overlying relation to the member 24 with the aid of a layer of pressure-sensitive adhesive, as shown in broken lines in Fig. 3, care being taken to dispose the holes 20 in the flap in line with the holes 26 in the blank 30.
