Definitions

• the present invention relates to a resealable dis ⁇ pensing container of the type comprising a container body formed with at least one dispensing opening and a flexibl sealing flap having a seizable cover portion which is adapted either to be removably secured, by adhesion to said container body, over the dispensing opening to cover this, or to be moved away from said container body, there- by exposing the dispensing opening, said sealing flap also having an attachment portion which is adapted to retain said sealing flap on the container body, when the cover portion is moved away from the container body.
• a dispensing container of the type described above, intended for wet wipers and the like, is disclosed in EP- Al-0,030,348.
• a dispensing container described in this document is shown in Fig. 1 in a perspective view in the accompanying drawings.
• the container in Fig. 1 comprises a flat, rectangular container body generally designated 1 and made of a liquid-impermeable sheet material.
• the sheet material is folded along two longitudinal edges 2, 3 of the body 1 and sealed by two end lines of weld 4, 5 and a longitudinal bottom line of weld (not shown).
• One main surface 6 of the con- tainer body 1 is formed with an elongate dispensing open ⁇ ing 7 through which e.g.
• the dispensing container also comprises a sealing flap generally designated 8.
• This comprises a seizable cover portion 9 and a smaller attach- ment portion 10.
• One sl. ⁇ e of the cover portion 9 is pro ⁇ vided with a continuous adhesive layer 11 so as to be removably securable to said main surface 6 of the con ⁇ tainer body 1 and be able to cover the dispensing opening 7.
• the cover por ⁇ tion 9 carries, via the adhesive layer 11, a non-adhesive member 12.
• the non-adhesive member 12 can advantageously be made of the part of said sheet material, which is left as the dispensing opening 7 is punched. In Fig. 1, the non-adhesive member is not connected with the container body 1.
• EP-A-0,030,348 further discloses a variant of the dispensing container shown in Fig. 1.
• This variant is illustrated in Fig. 2 in the accompanying drawing, where the same parts as in Fig. 1 have been given the same reference numerals.
• the design is the same as in Fig. 1, except that the non-adhesive member has the shape of a tongue 12a which is integral with the container body 1. This solution promotes the positioning of the tongue 12a in the dispensing opening 7 when the sealing flap 8 is closed.
• EP-Al-0,030,348 also discloses a variant in which the container body 1 further comprises an internal partition for forming two separate spaces for e.g. wet wipers in one space and dry wipers in the other.
• the container body is provided with a further dispensing opening and a further sealing flap.
• sealing flap 8 In resealable dispensing containers of this type it is important that the sealing flap 8 can be closed and opened a great number of times, without the sealing flap 8 or the container body 1 being damaged.
• the sealing flap 8 It is also important that each time the sealing flap 8 is closed by adhesion to the container body 1, it takes a predetermined position relative to the container body. This is particularly important if the dispensing container accommodates moist contents, such as wet wipers, since an incorrect, not tight positioning of the closed sealing flap 8 can damage the contents. If the sealing flap is provided with a non-adhesive member, for example the mem ⁇ ber 12, 12a in Figs. 1 and 2, it is still more important that the sealing flap 8 is correctly positioned each time it is closed, since, as mentioned above, the non-adhesive member 12, 12a is made of the same liquid-impermeable sheet material as the container body 1 and, thus, promotes the liquid sealing of the dispensing opening 7.
• a non-adhesive member for example the mem ⁇ ber 12, 12a in Figs. 1 and 2
• Such an incorrect positioning of the sealing flap 8 as it is closed, can occur if the sealing flap 8 is inad- vertently entirely pulled off from the container body, i.e. if the attachment portion 10 of the flap 8 comes off completely from the container body 1.
• An incorrect posi ⁇ tioning of the sealing flap 8 can also occur if the attachment portion 10 is damaged as the sealing flap is opened, so that only part of the attachment portion 10 is connected with the body 1.
• the sealing flap 8 can, as it is opened, break in the area where the cover portion 9 passes into the attachment portion 10, i.e. the cover portion 9 can, by mistake, be fully detached from the attachment portion 10.
• Fig. 3 shows a dispensing container according to the above-mentioned EP-Al-0,030,348 which has been improved according to EP-B1-221,168.
• Fig. 3 is a schematic top plan view of the sealing flap 8 and the cover portion 9 and the attachment portion 10 thereof.
• the attachment portion 10 is secured by a transverse line of weld 13.
• a dashed line 15 indicates the contour of the dispensing opening 7, and the improvement consists in the ends of this non-closed contour line 15 ending in two out- wardly directed curves 15a, 15b.
• the two curves 15a, 15b are adapted to prevent the tongue 12a, without being damaged, from being pulled too far backwards toward the attachment portion 10.
• FIG. 4 shows an exposed sealing flap 8 as seen from underneath.
• the lower side or the surface of the sealing flap 8 facing the container body 1 is provided with a first adhesive layer 11a extending over the cover portion 9, and a second adhesive layer lib extending over the attachment portion 10.
• a transverse, non-adhesive area 16 of the sealing flap 8 extends between the two adhesive layers 11a and lib.
• the sealing flap 8 comprises an attachment tongue 17 which, together with the portion 18 of the sealing flap 8 to the left of the line 19, forms the attachment portion 10 of the sealing flap 8.
• the attach- ment tongue 17 is enclosed by two parallel slits 20, 21 and a curved slit 22 connecting the ends of the parallel slits 20, 21.
• the other ends of the slits 20, 21 terminate in two small apertures 23, 24.
• the apertures 23, 24 serve to prevent such tearing, but they do certainly not provide full security.
• Problems and suggested solutions in connection with resealable dispensing containers of the type mentioned by way of introduction have now been discussed in respect of unintentional, complete detachment of the sealing flap 8 and undesired damages to the dispensing container.
• a further drawback of dispensing containers of the type mentioned by way of introduction e.g. the dispens ⁇ ing container according to the above-mentioned EP-A1- 0,030,348, is that the user must use both hands to open and close the container, one to hold the container body and the other to seize and open or close the sealing flap.
• the present invention has been developed to solve the above problems, and a main object is to provide a reseal- able dispensing container of the type mentioned by way of introduction, in which the sealing flap can be closed and opened a great number of times, with no risk whatsoever that neither the sealing flap nor the container body will be damaged, and with no risk whatsoever that the sealing flap, when opened, will be completely detached from the container body, i.e. that the attachment portion releases the container body.
• the invention is charac ⁇ terised in that the sealing flap, when the cover portion is secured over the dispensing opening, is bent or deflected round an edge or an edge side of the container body in an area of the sealing flap where the cover por ⁇ tion passes into the attachment portion.
• the sealing flap can be bent round such a folding edge which is shown in, for example, Fig. 1 at reference numeral 2 or 3 and which forms an edge line between two substantially parallel main surfaces of the container body.
• the sealing flap can also be bent over the entire edge surface, so that the cover portion engages one main surface and the attachment portion engages the other.
• edge or edge side should also be considered to be included in the case where the sealing flap is bent in an area of the container body where this passes between the surfaces to which the cover portion and the attachment portion are secured, the tran ⁇ sition being smooth without one or more sharply defined edge lines.
• the novel and specific feature of the invention is that the sealing flap, when the cover portion has been entirely pulled off from the container body, thereby exposing the dispensing opening, will be substantially quite straight, especially in the area where the cover portion passes into the attachment portion. Thus, the sealing flap will not be folded sharply backwards in said area, as the flap is opened. Such backward folding is marked at reference numeral 25 in Figs. 1 and 2. According to the invention, the tractive forces acting upon the attachment portion will therefore only be directed in parallel with the attachment portion, not perpendicularly to the surface to which the attachment portion is secured.
• a piece of adhesive tape can be applied to the surface of a table, and then, for removal, one end of the piece of tape is pulled. If this end is pulled in the direction of and over the piece of tape, this will easily be removed, but if the same end is instead pulled in the direction away from the piece of tape parallel to the sur ⁇ face of the table, the adhesive layer of the piece of tape will effectively counteract the attempt at removal.
• a dispensing container which, in addition to the above-mentioned features, comprises a suspension means, such as a hole in the container body or a hook or the like connected with the container body, said suspension means being arranged in such a manner that said edge or edge side, when the dispensing container is hung by the suspen ⁇ sion means, constitutes a lower horizontal edge or edge side of the container body, and a downwardly directed tractive force exerted on the sealing flap for exposing the dispensing opening does not move said edge or edge side from its horizontal direction.
• a suspension means such as a hole in the container body or a hook or the like connected with the container body
• inventive dispensing container is provided with such a suspension means, it can be hung on a wall and be opened and closed by one hand only, which is a great advantage in many contexts.
