Description

Packaging

Technical Field of the Invention

The present invention relates to packaging and in particular to packaging that can be resealed after use.

Background to the Invention

In many situations, packaging is provided in which, upon removal of a product from the packaging through an opening, a second product is presented to the user for removal.

In situations where the product concerned consists of a wet or moist article, it is desirable to provide a means of preventing the article from drying after opening the packaging. This is commonly achieved by resealing the packaging using an adhesive cover. This s&ution may not be adequate in environments where a high level of hygiene is required as there is a risk of contamination to the remaining products when the user comes into contact with the adhesive cover each time the packaging is used.

lii addition, it is very easy for an article to be partially removed from the packaging which then lies partially outside of the packaging and is prone to dehydration and affecting the ability for the adhesive cover to successfully re-seal the opening of the packaging. These problems are particularly relevant where the product is a medical or surgical product such as a medical or surgical wipe, for example.

It is an aim of preferred embodiments of the present invention to provide packaging that at least partially overcomes at least one problem of the prior art.

The front panel 4 comprises IS side edges 26, 26' and abase edge 26" and the rear panel 6 comprises corresponding side edges 28, 28' and base edge 28". The front panel 4 and rear panel 6 are separated by a middle section 12 comprising two lines of perforations 14. 14' located equidistant on either side of a fold line 16. A first surface 30 of a resealaNe closure, and a second surface 32 of a resealable closure are located on opposite sides of the fold hue 16. Figure 1 also shows the eventual location of a partition comprising two areas 18, 18' located on the front panel 4 and the rear panel 6, the partition areas 18, 18' spanning the panels 4, 6 with gaps 20 between the partition areas 18, 18' and the respective panel edges 26, 26', 28, 28' which will be formed as described hereafter.

The upper section 8' of the front panel 4 is transparent in part so as to provide a viewing window 22.

Referring to Figures 1 and 2, in use, the blank 2 is folded along the fold line 16 of the middle section 12 to bring together the front panel 4 and the rear panel 6.

The side edges 26, 26', of the front panel 4 are sealed to the corresponding side edges 28, 28', of the rear panel 6 using thermal sealant or heat welding. Upon sealing the front panel 4 to the rear panel 6 a container body is formed which is open at the edges 26", 28" of the front panel 4 and the rear panel 6. The lower section formed between lower sections 10, 10' of the open container is then filled with moist wipes. The open edges 26", 28" are then sealed to form a sealed container. A partition 118 is formed by sealing the partition area 18 on the rear panel 6 to the partition area 18' on the front panel 4 by crimping and heat welding. The formed partition 118 divides the formed enclosure into an upper portion 106 and a lower portion 108.. The joining of the front panel 4 to the rear panel 6 also brings together the first surface 30 of the resealable closure and the second surface 32 of the resealable closure to form a resealable closure 24, and the first line of perforations 14 and the second bile of peiforations 14' to form a single line of perforations 122.

Figures 2 and 3 show an embodiment of the present invention showing packaging 100 formed from the blank 2 containing wet articles in the form of wipes 102. Figure 2 is a perspective view with a front section cut away so as to illustrate the inside of the packaging 100 and Figure 3 is a side cross-sectional view of the packaging 100. The packaging 100 comprises a container 104 within which the partition 118 separates the container 104 into an upper portion 106 and a lower portion 108.

The partition 118 comprises an opening 110 and a downwardly directed slope 112 from the opening 110 towards the edge of the container 104. The edge of the partition 118 is joined to the container 104 walls in part so that there is provided a gap between the partition 118 and a portion of the first panel 4 and rear panel 6 of the container 104.
