Description

[0001] Paper container

[0002] The present invention deals with a transport system comprising an outer container and a paper container comprising a base body, which is made from a paper bag and comprises two opposite end faces, two opposite longitudinal sides, an upper side and an underside, and a longitudinal seam which extends between the two end faces along the upper side.

[0003] Nowadays, many everyday items are ordered from stores and supermarkets and then delivered to the customer by a carrier. This is particularly popular in cities, as shopping can be done with little effort and without having to search for parking spaces, which are usually rare. For this purpose, stores and supermarkets often have an online platform where the customer selects the desired products, for example fresh food such as fruit or vegetables, baked goods or canned goods, but also sanitary products, and places them in the virtual shopping cart.

[0004] The store or supermarket has reusable containers, which can also be called totes, preferably made of plastic, which are used to deliver the goods ordered. These containers are outer containers. The outer container is preferably in the form of a basket. It preferably has a rectangular base, which often has rounded comers. The base surface is preferably not solid, but has a large number of holes and openings and is therefore referred to as a basket. The base surface is surrounded by side surfaces, which may also have holes and openings. Such a basket is open at the top and preferably has no lid. It is therefore possible to place objects and goods in the copy without having to open a lid. The goods are put together and loaded into the outer containers, which are then brought to the customer by the carrier. The outer containers can and should be recycled in order to minimize the amount of waste produced. However, this means that the customer must immediately remove the delivered products from the plastic container to give the carrier the opportunity to take the outer container away again and reuse it. As in this case groceries are in direct contact with the open reusable container, hygiene and unitization can be on risk.

[0005] In order to do this as quickly as possible, the selected products are often not placed directly in the outer container, but arranged in a paper liner inside the plastic container. These paper liner are usually made from an unsealed piece of a paper tube that is sewn shut at both ends. The products can be inserted into the paper liner through the open longitudinal seam, wherein the paper liner can then be used to remove them all together from the outer container.

[0006] The disadvantage is that, on the one hand, the opening is not optimally designed for inserting products and, on the other hand, the sewn ends of the paper liner mean that the storage space actually available in the plastic container cannot be optimally utilized. In addition, the paper liner is relatively unstable, which is particularly noticeable when heavy products, such as tinned food, are to be transported.

[0007] The invention is therefore based on the task of proposing a transport system which eliminates or at least mitigates these disadvantages of the prior art.

[0008] The invention solves this task by a transport system comprising an outer container and a paper container positioned in the outer container, wherein the paper container comprises a base body, which is made from a paper bag and comprises two opposite end faces, two opposite longitudinal sides, an upper side and an underside, and a longitudinal seam which extends between the two end faces along the upper side, characterized in that the base body comprises at least one separation line along which a hinged flap can be separated from the rest of the base body, the at least one separation line extending from the longitudinal seam. This kind of paper container is known from prior art and is used for transporting bulk goods, like cement or concrete. Such paper container are frequently referred to as paper bags. The often come with a built-in valve that allows to introduce a powder material during filling. The valve is often located on one of the two end faces and can be closed after filling the paper bag so that the contents are protected against moisture and product spillage.

[0009] The paper bag is made from a paper tube, which can be single-layered or multilayered. The layers of paper to be used are folded to form a tube, resulting in the longitudinal seam of the tube, which is then sealed using adhesive, for example. The tube, which is still in continuous form, is then cut into tube pieces of the desired length, each of which can be used to produce a paper bag. The two end faces of the paper bag are formed from the open ends of the paper tube by folding them into a bottom, for example a cross bottom, which is then also closed using an adhesive. This type of paper sack is generally used to package and transport bulk goods in the form of powder or granules, for example.

[0010] The invention solves the problem posed by a paper container for such a transportation system, which comprises a base body, which is made from a paper bag and comprises two opposite end faces, two opposite longitudinal sides, an upper side and an underside, and a longitudinal seam which extends between the two end faces along the upper side, characterized in that the base body comprises at least one separation line along which a hinged flap can be separated from the rest of the base body, the at least one separation line extending from the longitudinal seam.

[0011] The paper bag used for the paper container is preferably made from a sheet of paper folded to form the paper tube as described above.

[0012] When the paper container or transport system according to the present invention is used, the paper container is first placed in the outer container, if this has not already been done. The paper container is opened. For this purpose, the hinged flap is separated from the rest of the base body along the separation line. The separation line serves to separate the material of the base body along this line and thus form the flap. As the separation line extends from the longitudinal seam, which is also opened or has already been opened, the flap is separated from the rest of the base body on at least two adjacent sides and can be opened.

[0013] In a preferred embodiment of the present invention the at least one separation line extends towards one of the longitudinal sides. In a particularly preferred embodiment the at least one separation line extends up to one of the longitudinal sides. This means, the separation line reaches the edge between the upper side of the base body and the respective longitudinal side. Preferably, the at least one separation line extends along an edge between the upper side and one of the two end faces.

[0014] In a preferred embodiment of the present invention the base body comprises two separation lines, wherein the flap is positioned between the two separation lines. In a particularly preferred embodiment of the present invention, the two separation lines each extend along an edge between the upper side and one of the end faces. Ones these two separation lines are used and the material of the base body is separated along these lines there is a hinged flap, that covers one complete part of the upper side of the base body. The upper side of the base body, comprises two parts, each of which are between the longitudinal seam and an edge between the upper side and one of the longitudinal sides. When the longitudinal seam is positioned in the middle of the upper side of the base body, then both parts of the upper side are of equal size. When the longitudinal seam is not positioned in the middle of the upper side, then the two parts of the upper side have different sizes. In this case it is advantageous when the at least one separation line, preferably both separation lines extend from the longitudinal seam along the larger of the two parts of the upper side. This results in a larger hinged flap and thus a larger opening once the at least one separation line has been used.

[0015] In a preferred embodiment there is at least one separation line on each of the two parts of the upper side. Especially preferred, there are two separation lines on each of the two parts of the upper side, which then results in two hinged flaps and thus an even larger opening. The larger the opening is, the easier can the paper container be filled with goods of various sizes. Preferably, the base body has at least one closing element that preferably comprises at least one adhesive element, to close the longitudinal seam at least partially, but preferably fully. The closing element can be covered by a removable cover. Once the paper container is filled, the cover is removed from the closing element and the longitudinal seam can be closed. In the closed state the goods inside the paper container are protected against falling out of the container. The closed longitudinal seams also provides for additional stability of the paper container.

[0016] Preferably, the separation lines are perforated or cutted lines. In a preferred embodiment each of the end faces comprises a cross bottom. In a preferred embodiment at least one of the end faces, preferably both end faces, comprise a handle.

[0017] In a preferred embodiment of the present invention the paper basic weight is at least 90 g / m2, preferably at least 100 g / m2, most preferably at least 110 g / m2and a maximum of 130 g / m2, preferably a maximum of 120 g / m2, most preferably a maximum of 110 g / m2. The paper basic weight is measured according to ISO 536:2012.

[0018] Preferably, the paper burst strength is higher than 450 KPa, measured according to ISO 2758:2014.
