- the support panels connected to the second lid panel provides support and counteracts the second lid panel being pushed downwardly into the interior of the package. While piled up during transportation the lid will not come off because of the adhesive and the pressure from the other packages on the adhesive.
- the first lid panel may be provided with a tear line extending transversely across the first lid panel.
- Extending across is in this context intended to refer to an extension across the full width of the first lid panel.
- the tearing of the first lid panel along the tear line may be facilitated by the provision of a local weakening of the material, such as by the provision of a perforation or at least a tear initiating cut, and/or by the provision of a local strengthening, such as by the provision of a tear string.
- the local weakening and/or local strengthening need not extend across the full width of the first lid panel. However, preferably the local weakening and/or local strengthening extends at least along a major part of the transversal extension of the first lid panel.
- the first lid panel is adhesively connected to the second lid panel at a first position on the first lid panel, as seen along the longitudinal direction

- the first and/or the second lid panel is provided with a second adhesive strip, preferably a second preinstalled adhesive strip, which preferably still is protected by a cover strip, wherein the second adhesive strip is, as seen along the longitudinal direction, positioned where there still is an overlap between the first and second lid panels even though the first lid panel has been reduced in length by being torn along the tear line.
- This second adhesive strip may e.g., be used for reclosing the package. This may e.g., be useful in case the package is used of commercial applications where some of the goods often is returned to the original sender.
- the closed package may be opened easily. Moreover, it is also apparent if someone has opened the package earlier.
- the blank may further comprise two additional support panels being oppositely arranged on a respective one of two oppositely arranged longitudinally extending sides of the first lid panel, wherein each additional support panel has, as seen in a flat-laid state of the blank, a transversal extension being equal to a transversal extension of the respective one of the end wall panels, such that a transversely outer edge of the respective additional support panel as seen in a flat-laid state of the blank, is capable of extending to and abut the inner major surface of the bottom panel when the blank is erected to form the package.
- the package With the two additional support panels being capable of abutting the inner major surface of the bottom panel the package will get further improved stability both during transportation and when stacked.

- the additional support panels may each be configured to be situated at the inside of the end walls formed by the end wall panels when the blank is erected to form the package, such that the respective additional support panel extends with an outer major surface thereof along an inner major surface of the respective end wall panel.
- the end walls will aid in keeping the support panels in its intended position and thereby further stabilize the first lid.
- a longitudinal extension of the first lid panel is preferably at least 60% of a longitudinal extension of the bottom panel, and more preferably 100%.
- first lid panel With the longitudinal extension of the first lid panel being at least 60% of the longitudinal extension of the bottom panel, it is facilitated to provide an overlap of the first and second lid panels, whereby the first lid panel will get support from the second lid. If an overlap of the first lid panel over the second lid panel would be too small, the support from the second lid would be too weak.
- first lid panel 100% of the longitudinal extension of the bottom panel the first lid will create a smooth top surface of the package which facilitate the stability for the package during the transport of the stacked packages. It may be noted that 100% may in practice be a few millimetres shorter such that it is secured that the first lid panel does not extend past the plane of outer major surface of the second end wall.
- a longitudinal extension of the second lid panel is preferably between 10% and 50% of the longitudinal extension of the bottom panel, and more preferably between 20% and 40%.
- the second lid covering less than half of the bottom panel an efficient use of material is secured, and the second lid covering at least 10% is considered a practical lower limit where there still is provided a distinct improved stability from the second lid for the first lid.

By securing that such a kind of folding is not possible it is made easier to fold the blank in the intended manner in which the support panels are capable of abutting the inner major surface of the bottom panel.
- the longitudinal extension of the first lid panel is preferably greater than the longitudinal extension of the second lid panel, more preferably between 200% and 600%.
- a longitudinal extension of the support panels is preferably at least 50% of the longitudinal extension of the second lid panel, and more preferably at least 90%, wherein preferably the transversely outer edge of the respective support panel which is configured to abut the inner major surface of the bottom panel has a longitudinal extension being about 40-80% of the longitudinal extension of the second lid panel.
- the transversely outer edge of the respective support panel need not have the full longitudinal extension of the support panel.
- the support panels extend along the full longitudinal extension of the second lid panel, at least as seen along the connection between the support panels and the second lid panel.
- the corner between the transversely outer and longitudinally extending edge and the transversely extending edge closest to the second side wall panel is rounded or chamfered, whereby the transversely outer and longitudinally extending edge of the respective support panel abuts the inner major surface of the bottom panel along a length being about 40-80% of the longitudinal extension of the first lid panel.

- the support panels 60a, 60b extend along the full longitudinal extension of the second lid panel 50, at least as seen along the connection between the support panels 60a, 60b and the second lid panel 50.
- the corner between the transversely outer and longitudinally extending edge and the transversely extending edge closest to the second side wall panel 22 is rounded or chamfered, whereby the transversely outer and longitudinally extending edge of the respective support panel abuts the inner major surface of the bottom panel along a length being about 40-80%
- the longitudinal extension of the additional support panels 70a, 70b may be between 40% and 80% of the longitudinal extension of the first lid panel 40, and wherein preferably the transversely outer edge 70a1, 70b1 of the respective additional support panel 70a, 70b configured to abut the inner major surface of the bottom panel 10 has a longitudinal extension being about 30-70% of the longitudinal extension of the first lid panel 50.
- the transversely outer edge of the respective additional support panel 70a, 70b need not have the full longitudinal extension of the additional support panel 70a, 70b.
- the additional support panels 70a, 70b extend along the full longitudinal extension of the first lid panel 40, at least as seen along the connection between the additional support panels 70a, 70b and the first lid panel 40.
- the corner between the transversely outer and longitudinally extending edge and the transversely extending edge closest to the second side wall panel 22 is rounded or chamfered, whereby the transversely outer and longitudinally extending edge of the respective support panel abuts the inner major surface of the bottom panel along a length being about 30-70%.
- the longitudinal extension of the second lid panel 50 is under 50% of the longitudinal extension of the bottom panel 10.
- the longitudinal extension of the second lid panel 50 may be between 10% and 50% of the longitudinal extension of the bottom panel 10, and preferably between 20% and 40%. In the preferred interval a good balance between stability and usage of material is reached.
- the longitudinal extension of the second lid panel 50 may be greater than a longitudinal extension of the second side wall panel 22, preferably between 120% and 200% of the longitudinal extension of the second side wall panel 22.
- first and the second side wall panels 21, 22 preferably have the same, or alternatively expressed corresponding, longitudinal extensions, such that the distance between the bottom panel 10 and the lid panels 40, 50, i.e., the height of the package 200, is the same along the longitudinal direction.
- end wall panels 30a, 30b preferably have the same, or alternatively expressed corresponding, transversal extensions, such that the distance between the bottom 10 and the lid panels 40, 50, i.e., the height of the package 200, is the same along the transversal direction.
- the longitudinal extension of the first lid panel 40 may be greater than the longitudinal extension of the second lid panel 50, preferably between 200% and 600% in such way that the first lid panel 40 covers the second lid panel 50 at least partly when the blank 1 is folded to the package 200.
- the longitudinal extension of the first lid panel 40 may be at least 60% of a longitudinal extension of the bottom panel 10, and preferably 100%, or at least close to 100%, which is best disclosed in Figure 4 .
- 100% may in practice be a few millimetres shorter such that it is secured that the first lid panel does not extend past the plane of outer major surface of the second end wall.
- the first lid panel With the longitudinal extension of the first lid panel being at least 60% of the longitudinal extension of the bottom panel the first lid panel will get support from the second lid. If an overlap of the first lid panel over the second lid panel would be too small, the support from the second lid will be too weak. With a longitudinal extension of the first lid panel being 100% of the longitudinal extension of the bottom panel the first lid will create a smooth top surface of the package which facilitate the stability for the package during the transport of the stacked packages.
- the blank 1 configured to be erected into a package 200 may, as an example, be designed without the additional support panels 70a, 70b or without the outer end wall panels 90a, 90b and without both of them.
- the blank 1 may include extra tear lines and optionally also include extra adhesive strips.
