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. Representative constructions of such a container are shown in U.S. Patent No. 4,420,080.
- a primary problem which has arisen with the aforesaid known 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 movement 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-shaped cuts formed therein each
- 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
- 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.

- the flap 16 further has an end region 16a by which 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.

Abstract
Description
- 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.
- It is often necessary to provide an inexpensive 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. 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. In order to prevent the adhesive from coming into contact with the contents of the container, 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. Representative constructions of such a container are shown in U.S. Patent No. 4,420,080.
- A primary problem which has arisen with the aforesaid known 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.
- The aforesaid primary problem is overcome by 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, wherein 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 movement 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, and wherein 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; which container is characterized in that the flap has a pair of opposing, generally L-shaped cuts formed therein each of which starts at a respective one of the side edges of the flap and has a first portion extending transversely inwardly of the flap intermediate the ends of the latter and continues with a second portion extending generally longitudinally of the flap toward and terminating at the line of attachment, with the two second portions of the L-shaped cuts being spaced from each other by a distance greater than the width of any portion of the non-adhesive member located between the second portions of the cuts, in that the two L-shaped cuts define at the remote sides of the second portions thereof a pair of generally longitudinally extending tabs or fingers constituting respective integral enlargements of the one end region of the flap so as to enhance the anchoring of the flap to the front side of the container, and in that the flap further has a pair of tear prevention holes formed therein which are located on the line of attachment and each at the termination of a respective one of the second portions of the L-shaped cuts, whereby a tearing of the flap beyond the line of attachment and off the container is effectively inhibited.
- The aforesaid secondary problem is overcome by 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.
- Brief Description of Drawings
- 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.
- Referring now to the drawings, 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 asealing device 14 including aflap 16 which covers and uncovers anopening 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 alayer 28 of pressure-sensitive adhesive, and anon-adhesive member 24, which is smaller than theflap 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 themember 24 also overlies theopening 18 and prevents the adhesive on the flap from coming into contact with the container contents, e.g. tissues, towelettes, and the like. Theflap 16 further has an end region 16a by which it is permanently secured to the front side of the container and at its opposite end has afinger 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). - In accordance with the basic concept of the present invention, tearing of the
flap 16 beyond the line of attachment upon opening of thesealing device 14 is prevented by the provision of a pair of generally L-shaped cuts 19a/19b and an associated pair oftear prevention holes 20 in theflap 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 asecond 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. Thetear prevention holes 20 are formed on the line of attachment and at the terminations of their associatedportions 19b of the L-shaped cuts. The transverse spacing between thelongitudinal cut portions 19b is somewhat greater than the width of any portion of thenon-adhesive member 24 that is located between those portions of the cuts. - As clearly shown, by virtue of the L-shaped cuts the
flap 16 has a pair of generally longitudinally extending tabs orfingers 16b defined at the remote sides of thesecond portions 19b of the cuts, which tabs or fingers are integral enlargements of the end region 16a of the flap. The tabs orfingers 16b serve to enhance the ability of the end region 16a to anchor theflap 16 to the front side of thecontainer 10. It will be understood that in this basic embodiment of the invention, thenon-adhesive member 24 of thesealing 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. - Alternatively, in accordance with a further aspect of the present invention, 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 thecontainer 10 is constituted, such that themember 24 has amain 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 thesecond portions 19b of the L-shaped cuts and terminating at the uncut end of the tongue portion 24b remote from themain 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 theflap 16, and tearing of themember 24 beyond the second line of attachment is prevented by the provision of a second pair oftear 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 themember 24. Themember 24 is adhesively secured to the coated face of theflap 16 for joint movement therewith when the flap is moved from its closed position (Fig. 1) to its open position (Fig. 2). - It will be understood that the two sets of
tear prevention holes flap 16 and between, on the other hand, the tongue portion 24b of themember 24 and the front side of thecontainer 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. - For the purpose of making 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 orthe 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 simultaneously 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 anon-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 themain body portion 24a thereof. At the same time, two inner flaptear prevention holes 26 are die cut into blank 30. - In order to form the container, the sections 30a and 30b of the blank are laid over the back face of the section 30c of the blank with the
accordion folds 12 at the sides, theedges 32 and 32a are secured to theedge 40 by a permanent seal, theedges 34 and 34a are secured to the edge 42 by a permanent seal, and the overlappingedges resealable sealing device 14 is formed by attaching aclosure flap 16, the structure of which is as shown in Fig. 4, to the front side of the container in overlying relation to themember 24 with the aid of a layer of pressure-sensitive adhesive, as shown in broken lines in Fig. 3, care being taken to dispose theholes 20 in the flap in line with theholes 26 in the blank 30.
