Abstract
A sales packaging has a receiving part (1) provided with a flange
portion (2) enclosing an opening portion (3) of the receiving part and
an air-tight or barrier cover sheet (4,6) welded or bonded onto the
flange portion. The cover sheet comprises two layers with at least the
upper one (6) of air-tight or barrier material, connected by a
re-sticking glue or pressure-sensitive adhesive which layers are
connected along a surrounding peelable seal seam (10) with the upper
layer removable from the lower layer (4) and reattachable to the lower
layer. Within the area enclosed by the peelable seal seam the lower
layer is provided with a breaking line (5) which is broken or torn when
the upper layer is pulled off the lower layer.
Description
- The invention relates to a sales packaging with a product receiving part having an opening portion enclosed by a flange portion to which a barrier cover sheet is welded or bonded.
- In a known packaging of this type (WO 93/00274) an intermediate layer is arranged between an air-tight or barrier film layer generally transparent and connected to the flange portion by means of a peelable seal welding, and the flange portion which intermediate layer on the one hand may be used as a label and on the other hand may be adapted for reclosing the sales packaging after removal of the barrier film layer. For this purpose a rim portion of the intermediate layer is mounted on the flange portion by means of a re-sticking glue or adhesive outside of the opening portion of the packaging and can be partially pulled off for releasing the opening portion and thereafter re-attached to the flange portion by means of the re-sticking glue or adhesive to again cover or close the opening portion.
- This sales packaging fulfils most of the use requirements since the receiving part which normally consists of an air-tight or barrier material, is closed by the air-tight or barrier film layer which film layer needs not to carry information as to the contents of the packaging which after removing the film layer would be lost. When the sales packaging is brought to an open state by the user by removing the air-tight or barrier film layer then the contents of the packaging becomes accessible by simply pulling off the intermediate layer normally carrying information as to the packaging contents. Reclosing may be effected by pressing back the intermediate layer onto the flange portion wherein the information as to the packaging contents remains connected with the receiving part of the packaging.
- Whereas this prior sales packaging fulfils essentially all requirements on air tightness and recloseability, it is disadvantageous in so far as it requires two separate closure layers, the barrier film layer on the one hand and the intermediate layer on the other hand, and that the barrier film layer is removed upon first opening and is then no longer required.
- It is an object of the invention to improve a sales packaging so that the barrier film sheet can be used for reclosing the sales packaging.
- To achieve this object a sales packaging with a receiving part having an opening portion enclosed by a flange portion to which an air-tight or barrier cover sheet is welded or bonded, is improved according to the invention in that the cover sheet comprises two layers connected with each other by means of a repositionable adhesive e.g. a re-sticking glue or adhesive or a pressure-sensitive adhesive which layers are connected along a peelable seal seam with the upper layer being removable from the lower layer and reattachable thereto wherein at least the upper layer is a barrier layer and wherein the lower layer is provided with a breaking line within the area enclosed by the peelable seal seam which breaking line will be broken when the upper layer is pulled off the lower layer whereas the repositionable adhesive provided in the area between breaking line and peelable seal seam permits reattaching of the upper layer to the lower layer in this area.
- In the sales packaging according to the invention having a receiving part which may be cup-like shaped or may e.g. consist of a flexible, not dimensional stable receiving part like a flexible film, air-tight closing is effected by co-operation of the upper and the lower layer of the cover sheet wherein the lower layer is secured to the flange portion. The upper layer is connected to the lower layer on the one hand by a peelable welding seal or the like and on the other hand by bonding by means of a repositionable adhesive in the area within this peelable welding seal so that upon opening for the first time the upper layer is separated from the lower layer along the peelable welding seal or seal seam whereas in addition upon opening and reclosing a separation and a reconnection of upper and lower layer will occur in the area of the repositionable adhesive. Upon this first separation of upper layer and lower layer the latter is torn apart along the breaking line which may be formed by a perforation, so that the portion of the lower layer located within the breaking line is pulled off together with the upper layer to thereby release the opening portion of the receiving part. Reclosing can be effected by urging back the cover layer onto the flange portion so that the portion of the upper layer located outside of the breaking line and not covered by the lower layer is releasably bonded back onto the flange portion.
- The upper layer of the cover sheet may be connected with its lower layer after the latter has been attached to the flange portion of the receiving part, in particular if the receiving part consists of a cup-shaped element. However, it is also possible to prefabricate a web of upper and lower layer wherein the upper layer is preferably forming labels, and to then connect sections of this web forming cover sheets to successive receiving parts, in particular if the receiving parts consist of flexible film. In this case the upper layer and the lower layer forming the cover sheet may be of the same size so that the lower layer is completely covered by the upper layer.
- Preferably the lower layer is connected with the flange portion along an endless welding seam whereas the peelable seal seam is located in the area between the endless welding seam and the opening portion of the receiving part.
- To ensure that upon opening the sales packaging the upper layer with the part of the lower layer sticking thereon is not removed completely from the flange portion which would make it difficult to reclose the packaging, the breaking line may extend only along part of the opening portion. In such case the ends of the breaking line form a "stop" against complete removal of the cover sheet from the flange portion.
- The upper layer may carry printed information and thereby form a label which remains connected to the sales packaging for the entire period of use.
- Opening of the sales packaging is facilitated when the rim of the upper layer is provided with a grip portion or flap located completely outside of the area of the peelable seal seam. By gripping this grip portion or flap the upper layer can be pulled off without difficulties. When the upper layer and the lower layer are of the same size and polygonally, in particular rectangular or squarely shaped the grip portion or flap may be formed by a corner portion of the upper layer.
- In the following the invention is described in more detail with reference to the drawings.
- Figure 1
- is a perspective view of a partially opened sales pakkaging.
- Figure 2
- is a plane view on the closed sales packaging of Figure 1.
- Figure 3
- is a schematic exploded view of the sales packaging of Figures 1 and 2.
- Figure 4
- shows in a view corresponding to Figure 2 another embodiment of the invention.
- Figure 5
- shows in a view corresponding to Figure 3 the embodiment of Figure 4.
- The sales packaging shown in Figures 1 and 3 has a cup-shaped receiving
part 1 with an outwardly directedflange 2 at its upper rim 3' enclosing theopening 3. Generally thereceiving part 1 consists of moulded, air-tight or barrier plastic film. However, it may e.g. be in the form of a flexible film with the goods to be packed positioned on its middle portion. - On the outer rim area of the
flange 2 of the filled receivingpart 1 an air-tight or barrier cover sheet is secured by means of awelding seam 9. The squarely shaped cover sheet consists of alower layer 4 and anupper layer 6 with at least theupper layer 6 but preferably both layers formed by air-tight or barrier material. Theupper layer 6 which is slightly smaller than thelower layer 4, may form a printed label. - The outer rim portion of the
upper layer 6 is releasably connected with thelower layer 4 through a surrounding or endless peelable seal orwelding seam 10. At one side the outer rim portion of theupper layer 6 is provided with an outwardly projecting gripping portion orflap 7 which projects outwardly beyond thepeelable seal seam 10. In the area within the surrounding or endlesspeelable seal seam 10upper layer 6 andlower layer 4 are connected by means of a layer of a repositionable adhesive e.g. a re-sticking glue or a pressure-sensitive adhesive i.e. an adhesive which permits separating of the layers and reconnection thereof by pressing the layers together. - Somewhat outside of the edge 3' of the
opening 3 of thereceiving part 1 but within the area enclosed by the peelable seal seam 10 abreaking line 5 is formed in thelower layer 4 which breaking line may e.g consist of a perforation. Thebreaking line 5 extends, as can be recognized in Figure 2, along three edges 3' of theopening 3 and has its ends at a fourth edge thereof. The resistance of thebreaking line 5 against tearing is adjusted so that it is smaller than the bonding connection between theupper layer 6 and thelower layer 4 caused by the repositionable adhesive. - To open the packaging closed air tightly by the surrounding or
endless welding seam 9 betweenflange 2 andlower layer 4 the user grips the gripping portion or flap 7 and pulls off theupper layer 6 from thelower layer 4 as indicated in Figure 1 wherein thepeelable seal seam 10 is separated and also a breaking or tearing of thelower layer 4 along thebreaking line 5 occurs. During this process theupper layer 6 in the area betweenpeelable seal seam 10 andbreaking line 5 is pulled off the layer of repositionable adhesive provided on thelower layer 4 whereas the part of thelower layer 4 located within thebreaking line 5 remains bonded to theupper layer 6 due to the repositionable adhesive. As can be recognized pulling off theupper layer 6 from thelower layer 4 to the ends of thebreaking line 5 occurs without extensive resistance whereas upon reaching the ends of thebreaking line 5 the user feels a higher resistance which causes him to terminate the opening movement. - The packaging can be reclosed after opening by pushing back the
upper layer 6 onto the area betweenpeelable welding seam 10 and now brokenbreaking line 5 which area is provided with the reposionable adhesive. The contents of the packaging is protected against contact with the reposionable adhesive since the area of theupper layer 6 covering theopening 3 is covered by the part of thelower layer 4 which is located within thebreaking line 5 and is bonded to theupper layer 6. - In the embodiment of Figures 4 and 5 parts and elements corresponding to the parts and elements in the embodiment of Figures 1 to 3 have been designated with the same reference numerals but increased by "100". Therefore most of these parts and elements are not described again but can be understood as to structure and function from the description of the embodiment of Figures 1 to 3.
- Different from the embodiment of Figures 1 to 3 in the sales packaging of Figures 4 and 5 the
upper layer 106 is of the same size and shape as thelower layer 104 and is connected to thelower layer 104 through a surrounding peelable seal orwelding seam 110 that is located adjacent to the circumferential rim of both thelower layer 104 and theupper layer 106. Thepeelable seal seam 110 is located directly above theendless welding seam 109 which connects thelower layer 104 to theflange 102 of thereceiving part 101, and is separated from thewelding seam 109 by thelower layer 106. However, in Figure 4 it can be recognized that in the lower right hand corner thepeelable welding seam 110 is inwardly offset from the circumferential rim of both thelower layer 104 and theupper layer 106 so that atriangular flap 109 is formed by theupper layer 106 which is not bonded to thelower layer 104 and can therefore be gripped by the user to pull off theupper layer 106 from thelower layer 104. - As in the embodiment of Figures 1 to 3 in the area surrounded by the peelable seal seam 110 a layer of repositionable adhesive is provided between the
lower layer 106 and theupper layer 104 so that opening and reclosing of the packaging of Figures 4 and 5 can be effected in the same way as described in connection with the embodiment of Figures 1 to 3.
