Description

Paper-based container with a closure system, blank and method for producing a paper-based container with a closure system

description

The present invention relates to a paper-based container, in particular a child-safe container, comprising a base body with a front wall, a rear wall, at least two side walls and a base, which enclose a container interior, a lid which is pivotably hinged to the rear wall and which in a closed state closes the container and, in an open state, releases the interior of the container, the container having at least one paper-based closure system.

The invention further relates to a blank for such a container and a method for producing such a container from a blank.

In the prior art, containers made of plastics with child safety devices are known in particular. Such containers provided with child safety devices are used, for example, to store pharmaceutical products or detergents or cleaning agents. Plastics are among the most versatile materials for the manufacture of industrial goods. Containers made of plastics usually have high mechanical strengths, have a favorable ratio of strength and density, and are highly resistant to chemicals. Furthermore, containers made of plastics are comparatively inexpensive to manufacture and only require a low level of vertical integration.

Containers with child safety lock are used primarily for the transport and storage of consumer goods, in particular from the field of packaged detergents or cleaning agents and pharmaceutical products. Such detergents or cleaning agents are available to the consumer in a wide variety of forms. These can, for example, be present in the containers in packaged or unpackaged form, which means that the detergents or cleaning agents, in addition to powders and granules, also cleaning agent concentrates in the form of extruded or pelletized Compositions include. These solid, concentrated or compacted forms of administration are characterized by a reduced volume per metering unit and thus lower the costs for packaging and transport. Furthermore, in the past few years, detergent or cleaning agent producers have switched to offering such washing or cleaning agents in liquid, packaged form, in order to add one portion per washing or cleaning cycle. A popular form is pillow packaging with, for example, two to four chambers, each of which is filled with liquid detergents or liquid cleaning agents. The chamber system offers a needs-based solution for different challenges in washing or cleaning. When in contact with water, the chambers develop their full washing or cleaning performance in a targeted manner. The pillow packaging has a water-soluble film, which makes it quick and easy to use. The separate option of portioning detergents or cleaning agents also fulfills the consumer's desire for simple dosing. The corresponding means are comprehensively described in the prior art. Stable, safe and lightweight, resealable containers are required for convenient storage or removal of such detergents or cleaning agents. Paper-based containers usually combine such properties only unreliably.

In the area of stocking commercial quantities of these detergent or cleaning agent tablets, especially plastic containers in different material strengths, shapes and various locking and locking mechanisms are known. In recent years, however, consumers and companies have increasingly made efforts to avoid plastic-based products or to substitute them with renewable raw materials. Containers made from renewable raw materials, for example paper-based containers, however, due to the nature of the starting material, show significant deviations in production and in the technical properties compared to conventional plastic-based containers. Paper-based containers are not thermoplastically deformable and have limited durability and resistance to water, for example. Paper-based containers therefore have fundamental differences compared to plastic containers in terms of design and manufacturing method.

However, there are already a large number of paper-based containers with closure systems for a wide variety of uses. Such paper-based containers are used in particular as large-format detergent packaging containers or used to transport or stow general goods or merchandise. Corresponding packaging can, however, also be found in the field of cardboard boxes that have a self-closing mechanism, for example cardboard boxes for confectioners' needs.

However, the known paper-based containers do not meet the requirements of providing a reliable locking system which in particular includes a child-safe locking system according to ISO 8317 (2015) and at the same time can be operated easily by an adult. In addition, such paper-based containers often have poor rigidity and strength properties, in particular with respect to torsional forces acting on the container.

From EP 1 783058, for example, a child-resistant packaging container with a box body is known. The packaging container has a locking element with latching tabs which lie against the base body and which are accessible and unlockable via access openings formed in a cover. The Rastla rule with associated pass-through openings are arranged in pairs at a corner and unlocked with the thumb and forefinger of the hand of an adult. The locking tabs attached to the box body make the locking element susceptible to damage when you open and close it several times, since the locking tabs can easily be bent or destroyed, especially if the lid is closed improperly. In addition, the Verriege arrangement element, which is arranged in pairs at a corner and can be unlocked with the thumb and forefinger of the hand of an adult, is complicated in design and, for example, not suitable for adults with small gaps between thumb and forefinger.

Other paper-based containers with child safety locks are also often awkward to use, in that, for example, intuitive opening is not possible for the intended adult user. Furthermore, paper-based containers with a locking system, in particular with a child-proof locking system, often only have a short service life, i.e. the locking system is no longer secured against unwanted opening by children after just a few opening or closing processes by individual container elements do not have the desired durability due to the qualitative nature of the raw materials used. From the prior art, no containers made of renewable raw materials are known so far that provide a reliable and constantly operable locking system, in particular special according to ISO 8317 (2015), which is secured in particular against unwanted opening by children with sufficient stiffness properties at the same time of the container.

The present invention was therefore based on the object of providing a container that is formed on the one hand from a stable basic shape from renewable raw materials and on the other hand has a reliable and easy-to-use closure system that protects against unwanted opening and at the same time simple and in large numbers can be produced.

The object is achieved according to the invention with a paper-based container, in particular a child-proof container, of the type mentioned at the outset, the locking system comprising the following:

At least one latching lug, at least one latching lug recess corresponding to the at least one latching lug and at least one actuating element which is operatively connected to the at least one latching lug and is designed to cause the at least one latching lug to change between a locking position and an opening position, the at least one Latch on and the at least one actuating element are arranged in the cover and the at least one latch recess is arranged in the front wall and / or in at least one of the side walls, in particular in the inside of the front wall and / or in one of the inside of the side wall, in the closed state the at least one latching lug in the locking position engages with the at least one latching lug recess in such a way that the cover is locked on the base body to prevent it from opening automatically.

Such a paper-based container in particular meets the requirements of ISO 8317: 2015 for resealable child-resistant packaging.

Paper-based containers in the context of the invention are to be understood as meaning containers which are predominantly produced from paper-based raw materials, in particular paper-based raw materials made from plant fibers. Paper-based containers preferably use cardboard or, in particular, corrugated cardboard as the starting material, although also Container according to the invention made of cardboard or paper can be realized. The paper-based containers preferably have a rectangular plan, although a pentagonal or polygonal plan with a correspondingly larger number of side walls can potentially be implemented. There are thus containers with a different number of side walls possible. In particular, containers with two, three, four or six side walls can be used. Such containers with two side walls and a front wall and a rear wall are particularly preferred. The container is preferably intended to secure packaged goods, in particular detergents or cleaning agents, from unwanted access by children.

The essential difference compared to paper-based containers with locking systems according to the prior art is that in the locking system according to the invention, the entire movement mechanism is integrated in the hinged lid. The locking system is designed as a slide-swivel mechanism. A combination of the locking system and the lid, in which the mechanical movement mechanism is housed, with the base body that defines the interior of the paper-based container provides an opportunity to store and conveniently remove goods, in particular special detergents or cleaning agents. Thanks to the paper-based raw material, the container can be produced cost-effectively and automatically with a low net weight of the container at the same time. Due to the choice of raw materials, the container is recyclable and thus remains in the value chain.

Due to the slide-pivot mechanism of the container, which requires that the at least one latching lug be moved out of the at least one latching recess by means of the actuating element and must be held in the open position while the pivoting movement of the lid is being carried out, child safety is ensured Design of the container given. The child-safe functionality is given in particular by the fact that the actuation of the actuating element requires a basic understanding of the mechanical movement of a body in combination with coordinative abilities to open the lid. Both hands are preferably used to move the lid from the closed state to the open state. The lid is opened with one hand, which frees the inside of the container, and the second hand is used to fix the container, for example against undesired movement. More preferably, the first hand can actuate the actuating element and hold it in position, and the second Hand opens the lid by means of a swivel movement, which releases the interior of the container.

The interior of the container is preferably delimited in the upper region of the container by a partially encircling lid edge into which the lid can be pivoted at least in some areas.

In contrast to conventional paper-based containers with a locking system, all locking and unlocking means, that is to say the at least one locking lug and the at least one actuating element, are located on or in the lid in the container according to the invention, whereby the base body only contains the locking lug recesses of the locking system home. The technically complex components of the locking system are thus arranged on a relatively small area of the lid, which leads to a low complexity of the entire container and reduces the susceptibility to destruction. The base body can also be produced in this way in simple process steps, which contributes to cost-effective production.

The at least one locking lug is preferably made of a paper-based material, but in a preferred embodiment can be combined or treated with other materials in order to reduce signs of wear such as deformations and to further increase the durability of the container. The at least one locking lug is preferably an elongated flat element. The at least one locking lug is particularly preferably a partial extension of one side of the cover, more preferably an extension in the direction of the front wall.

The at least one locking lug recess is preferably formed by openings on the front wall of the paper-based container. The size of the openings corresponds to at least the dimensions of the at least one locking lug. The at least one locking lug recess is preferably formed on the inside of the front wall and is not accessible from the outside. In a particular embodiment, the latching recesses can be formed exclusively or additionally in at least one of the side walls, the at least one actuating element and the at least one latching nose then being formed in such a way that they are formed in the course of the side walls. The at least one actuating element is preferably also made of a paper-based material, but in alternative embodiments can be combined or treated with other materials in order to reduce signs of wear such as deformations and to further increase the durability of the container. The at least one actuating element can in principle have any shape and texture in order to come into engagement with the at least one latching lug in order to move it back and forth between the locking position or the opening position.

The structure of the container according to the invention ensures that the container can be reliably closed and opened, that is, the lid of the container is secured against undesired automatic opening by means of the locking system, in that the at least one latching lug locks the lid when the at least one locking lug is arranged in the at least one Rastnasenaus recess.

The arrangement of the at least one actuating element and the at least one latching lug in the lid of the container enables a compact design with high reliability at the same time. The arrangement of the at least one actuating element in the cover also ensures that no undesired actuation occurs, for example when the container is moved. Due to its arrangement, the actuating element can be actuated in a simple manner via the lid, so that when the lid is opened, the interior of the container is directly released within the operating radius of the user. Automatic opening is prevented by the fact that the at least one detent in the closed state creates a non-positive and / or positive connection between the cover and the base body.

To change the at least one latching lug between the locking position or the opening position, it is not necessary for the at least one latching lug to be arranged in the at least one latching lug recess. The change between the locking position or the opening position takes place in the same way when the lid is open, with the container naturally not being closed when the lid is open despite the locked position. An advantageous development is characterized in that the locking system is designed to be resilient in such a way that after the at least one actuating element has been actuated to open the container when the actuating element is released, the at least one latching lug is automatically returned from the opening position to the locking position. In this way, due to the resiliently designed locking system, the at least one locking lug is automatically pivoted back, which is a safety feature. The at least one locking lug is always in the locking position in the starting position and can only be transferred into the open position when the actuating element is actively actuated. This means that at least one locking lug is arranged to be mounted against spring preload. As soon as the force acts on the actuating element, the locking lug automatically moves back into the locking position under the influence of the spring preload.

A preferred embodiment is characterized in that the closure system on the lid comprises at least one transmission element that is operatively connected to the at least one actuating element and the at least one latching lug, which enables a force transmission between the at least one actuating element and the at least one latching lug. In this way, the locking system can be designed in different constellations and forces acting on the at least one latching lug from the actuating element can be arranged locally separated. The transmission element also supports the spring effect of the locking system and contributes to a stable design. The at least one latching lug is preferably formed from an extension of the transmission element, that is, in the case of a flat transmission element, the at least one latching lug lies in the same plane as the transmission element. The transmission element is particularly preferably hinged to the at least one actuating element.

Another preferred possibility is that the actuating element of the locking system is formed and fixed on the inside of the lid in order to prevent a change in position of the actuating element before, during and / or after a change between the locking position and the opening position. In this way, the actuating element is attached to the cover in the desired position. For this purpose, the actuating element is particularly preferably glued to the inside of the cover, for this purpose, for example, another can be attached to the actuating element. supply element articulated adhesive portion be present on which an adhesive is applied. The actuating element can, however, also be fixed by a plug connection, for example. The actuating element formed and fixed on the inside also increases the security of the locking system, since manipulation is prevented and the lid can be closed at any time without checking the correct positioning of the actuating element or the locking system.

In a further advantageous embodiment of the invention, the closure system further comprises at least one support element articulated on a cover surface of the cover, the at least one transmission element being articulated between the at least one actuating element and the at least one support element. The support element spaced the at least one latching lug out from the cover surface, whereby the at least one latching lug is supported on the cover surface and is thus designed to be movable. In this way, a safe transfer between the locking position and the opening position is guaranteed.

The at least one actuation element and the support element are arranged in the locking position at least substantially orthogonally to the cover surface. “At least essentially orthogonal” in the context of the invention means either orthogonal to the cover surface or almost orthogonal to the cover surface, i.e. H. with a maximum deviation of ± 10 °. The actuating element and the support element are also preferably formed in the open position slightly inclined in the direction of the rear wall.

In a further advantageous embodiment of the invention, the closure system is designed in such a way that the service life corresponds at least to the number of portions provided in the container, for example washing or cleaning tablets. However, it is particularly preferable for the closure system to allow even more opening and closing operations than corresponds to the number of portions. Such containers usually contain five to 20 portions, whereby preferably at least five to 20 operations of the closure system from the open state to the closed state can be carried out. The locking system is designed to be child-proof over its entire service life, which means that potentially harmful substances can be stored reliably and protected from unwanted access by children. Another useful embodiment of the invention is characterized in that the cover surface, the at least one support element, the at least one transmission element and the at least one actuating element enclose a trapezoidal cross-sectional area in the folded state. At least two of the inner angles of the trapezoidal cross-sectional area, in particular the angles adjoining the cover, are particularly preferred, at least in the locking position of the at least one latching lug, smaller than 100 °, in particular smaller than 90 °, and particularly preferably they are in the range between 89 ° and 80 °. Trapezoidal area in the sense of the invention is to be understood as the enclosed area, with trapeze-shaped not being understood in the narrow geometric sense; in particular, two lines do not have to be exactly parallel, but can also be present with deviations of +/- 5 °. However, the choice of angle ensures that the locking system has a reliable spring action. Paper-based raw materials, in particular cardboard, cardboard or corrugated cardboard, have special properties when subjected to bending. Such bending stresses occur primarily in the manufacture of packaging or paper-based containers in which geometric shapes are generated from cuttings by means of folds. When folding, paper-based raw materials, in particular cardboard or corrugated cardboard, have at least partially elastic properties up to a range of approximately 90 °. Paper-based containers are based on natural raw materials, which is why there can be a relatively high degree of variance. This means that the cardboard or corrugated cardboard pivots at least partially back into the starting position during a pivoting movement of up to approx. 90 ° and is thus at least partially dimensionally stable. This procedure makes use of the arrangement of the cover surface, at least one support element, at least one transmission element and at least one actuating element, in that they experience a slight change in orientation when the position of the at least one latching lug changes from the locking position to the open position. However, since the elements are preferably arranged at an angle of <90 °, the elements automatically pivot back into the starting position when the actuating element is released. In this way, the at least one latching lug automatically pivots from the open position into the locking position.

In a further advantageous embodiment of the invention, the support element and / or the actuating element extends essentially over the entire width of the container interior or over the entire length of the container interior. “At least essentially over the entire width / length” within the meaning of the invention that is, either over the entire width / length of the interior of the container or almost orthogonally to the cover surface, ie with a maximum deviation of 20% of the respective length / width. The width or length of the interior of the container is to be understood as the opening of the interior of the container that is to be closed by the lid. In this way, a stable locking system is ensured, which ensures locking security even with larger applied forces. In addition, the large-area elements allow different designs of the locking system to be set up, for example several or longer locking lugs, more stable components, etc.

A preferred embodiment is characterized in that the at least one locking lug is formed from a section of the support element. On the one hand, this reduces the effort involved in the production of the paper-based container, since the locking lugs can be produced, for example, by a punching process and formed by folding, and on the other hand, the locking lug is directly adjacent to the support element or transmission element, which results in a direct transmission of force when changing between the positions is ensured. More preferably, the latching lug formed in this way represents an extension of the transmission element, as a result of which a reaction to the latching lug automatically sets in when the transmission element is moved.

A preferred development of the invention is characterized in that the at least one actuating element comprises a force absorption area which acts on the at least one transmission element for force transmission in order to move the at least one latching lug between the locking position and the opening position. In this way, a defined area of the actuating element is given in which a reliable operation of the actuating element is given. In a preferred embodiment, the force absorption area is formed in the middle of the actuating element. Particularly preferably, the force absorption area can be designed as an independent element that acts on the actuating element.

In a further preferred development of the invention, the cover surface has at least one engagement opening on the outside through which the at least one actuating element formed in the cover, in particular the force absorption area of the at least one actuating element, can be actuated. Through the engagement opening, the actuating element or the force absorption area of the actuating element can be conveniently accessed via the cover surface. The dimensions of the at least one engagement opening preferably correspond to at least the circumference of the thumb of an average adult.

The container or the closure system is preferably provided with a seal, a band or the like, which ensures that only the intended products are filled with the desired quality criteria. The seal is preferably arranged in the area of the engagement opening, it being formed from an area of the lid, in particular by perforations of a section of the lid surface.

In a further advantageous embodiment of the invention, the transmission element extends essentially over the entire width of the container interior or over the entire length of the container interior, the transmission element completely covering the engagement opening and / or the transmission element completely separating the handle opening from the container interior. By covering the access opening, on the one hand, there is a further increased (child) protection of the container interior, since in this way no unintentional direct access to the container interior through the access opening is possible, on the other hand, delimiting the container interior also provides theft protection against unwanted removal of goods located in the interior of the container or an undesired insertion of products through the engagement opening.

An expedient embodiment of the invention is characterized in that the locking system comprises at least one limiting element which acts on the at least one actuating element and / or on the at least one transmission element and which limits the mobility of the at least one latching lug in such a way that the at least one latching lug in the locked state at least Essentially chen cannot be moved beyond the locking state against the direction of the opening state. The delimitation element ensures that the at least one transmission element, the at least one actuation element and the support element cannot be displaced beyond the locking position against the movement of the at least one latching lug in the direction of the opening position. This ensures that the elastic effect of the locking system is maintained over the entire life cycle of the paper-based container. Another useful embodiment of the invention is characterized in that the locking system has two to eight latching lugs, in particular three to five latching lugs, particularly preferably four latching lugs, and two to eight latching lug recesses each corresponding to the latching lugs, in particular three to five each with the latching lugs Corresponding locking lug recesses, particularly before given four locking lug recesses corresponding to the locking lugs. The corresponding number of latching lugs or the corresponding Rastna senausnehmungen is particularly dependent on the size or the desired locking effect of the lid with respect to the base body. The greater the Ver locking effect against the lid against forcible opening, that is, against unwanted opening without actuating the actuating element, the more locking lugs should be used. An enlarged Verriege treatment effect can preferably also be done by larger locking lugs or a deeper engagement of the locking lugs in the locking lug recesses.

Another expedient embodiment of the invention is characterized in that the container has two closure systems, the two closure systems being independent of one another. The locking systems formed can be actuated by means of separate actuating elements, each with separately movable latching lugs. A transfer of the container from the closed state to the open state is therefore only possible with a simultaneous transfer of the at least one latching lug from the locking position to the opening position. Containers with two locking systems are ideal if there are increased child safety requirements. Since both locking systems can only be operated separately, whoever needs the further increased coordination skills to transfer the cover from the locked state to the open state. Containers with two independent or separate closure systems thus each comprise an independent actuating element, the actuating elements being arranged in the lid and each being actuatable by means of an engagement opening formed on the outside of the lid, the actuating elements being in operative connection with at least one independently mounted There are latching lugs, the at least one latching lug being designed and configured to be in engagement with corresponding Rastna senausnehmungen in order to lock the lid against automatic opening. For a further increased child safety, the engagement openings on the lid are spaced apart from one another by a distance which corresponds to the average span between thumb and forefinger of an adult's hand. In this way, it is not possible for a child to unlock both actuators with one hand and to open the cover with the free hand at the same time.

A preferred embodiment is characterized in that the two locking systems with the latching lugs are designed and set up for engagement in at least one of the side walls and / or in the front wall. In the case of paper-based containers with two closure systems, the closure systems are preferably designed either in such a way that the closure systems engage in the side walls or engage in the front wall. A combination in the side and front wall is still possible.

An advantageous development is characterized in that the front wall and / or at least one of the at least two side walls is at least partially formed from a double wall having a cavity, the double wall being formed from an outer front wall and an inner front wall section from a one-piece front wall section hinged to the floor is, wherein the inner front wall section has the at least one locking lug recess, or wherein the double wall is formed from an outer side wall and an inner side wall section from an integral side wall section hinged to the bottom and / or to the front wall and / or to the rear wall, the inner side wall section being the has at least one locking lug recess. The formation of the front wall and / or the side walls as a double wall supports, on the one hand, the strength and rigidity of the container against pressure and torsional stress, and on the other hand, the cavity formed in the double wall provides a space into which the at least one locking lug extends can if it has passed through the at least one latching recess in the inner front wall section or inner side wall section. The double wall of the front wall and / or the side walls can be designed depending on the desired size of the cavity or the desired properties of the container. It is particularly advantageous if the front wall and / or the side walls are formed from an at least three-ply cardboard composite.

An expedient embodiment of the invention is characterized in that at least one of the at least two side walls is formed at least in some areas as a double wall, the double wall being composed of an outer side wall and one one-piece inner side wall section hinged to the front wall section is formed, the inner side wall section being arranged on the side facing the lid, or wherein the double wall is formed from an outer front wall and an inner front wall section from an integral inner front wall section hinged to the bottom, the inner front wall section being formed on the Lid facing side is arranged. Such a configuration is also known as the “Y- or V-shaped configuration” of the section. The formation of the side wall as a double wall supports the strength and rigidity of the container against pressure and torsional stress. It is particularly advantageous if the side wall is formed from an at least three-layer cardboard composite.

Another useful embodiment of the invention is characterized in that the inner side wall section is articulated to form a cavity on the outer front wall, or the inner front wall section is articulated to form a cavity on the outer front wall.

The object is also achieved by a blank, in particular a one-piece blank, for a paper-based container made of a foldable material such as cardboard or corrugated cardboard, the blank comprising: a bottom surface with at least two bottom flaps hinged to it, a rear wall surface hinged to the bottom surface two or more rear wall side surfaces articulated to the rear wall surface, a cover surface articulated to the rear wall surface, which has at least one cover surface opening tab that is movable on a tab fold line and partially cut out of the cover surface, a closure system cover surface element articulated on the cover surface, which has a support element articulated on the cover surface, a on the support element articulated transmission element and an actuating element articulated to the transmission element, wherein at least one latching lug is formed on the transmission element by a cutout from the support element, which is attached to the Outer front wall articulated to the bottom surface with at least one front wall side surface articulated to the outer front wall and the inner front wall section articulated to the outer front wall, the inner front wall section comprising the at least one, at least partially cut out, locking nose recess. With a blank configured in this way, there is a simple possibility of producing the paper-based container according to the invention from a one-piece body. Containers from such a blank can be effectively manufactured and have the specified dimensions and elements to create the functionality you want. In principle, the blanks can be available in almost all common sizes in order to produce the corresponding containers from them. The choice of the blank leads to a dimensionally stable and torsion-resistant container, which also has the locking system according to the invention and is therefore child-proof.

“One-piece blank” within the meaning of the invention means that the blank and thus also the container to be formed therefrom are formed from a single, coherent, paper-based folding blank. Alternatively, in certain embodiments, the blank can be assembled in advance from several individual parts, preferably in a cohesive manner, in particular by means of adhesives.

The articulated areas or sections are each articulated by means of fold lines introduced at least in part in advance. Such fold lines can be designed as folds, creases or perforations and are in particular introduced into the blank by upstream or downstream process steps. Such fold lines can particularly preferably include incisions, which simplifies the folding or positioning of the surfaces to be linked.

In a preferred embodiment, at least two reinforcement cover side surfaces are hinged to the cover surface, the reinforcement cover side surfaces each comprising movable reinforcement cover side surface tabs corresponding to the cover surface opening tab on a respective tab fold line partially cut out of the reinforcement cover side surfaces. In this way, the stability of the container to be produced and the security of the lid against undesired, improper opening are increased.

According to a further preferred embodiment of the invention, one or more front wall side reinforcement surfaces are hinged to the front wall side surface and / or the inner front wall portion with at least one corner section cutout at least partially between the front wall side reinforcement surface and the inner front wall portion and an inner front wall reinforcement surface that is hinged to the inner front wall portion. The front wall side reinforcement surface reinforces the front wall and / or the side wall against compressive and torsional stress by increasing the torsional stiffness. The corner section cut-out ensures that the side walls on the front wall adjoin this exactly. gene, in that the at least one corner part cutout leads to an excess-free arrangement of the walls to one another, which can only be placed in relation to one another in the specified cutout.

The object is also achieved by a further blank, in particular a one-piece cut, for a paper-based container made of a foldable material such as cardboard or corrugated cardboard, the blank comprising: a bottom surface with at least one bottom side outer wall linked to the bottom surface with at least one on the hinged bottom side inner wall, wherein the at least one bottom side inner wall comprises at least one, at least partially cut out, locking lug recess, a rear wall surface hinged to the bottom surface with two or more rear wall side surfaces hinged to the rear wall surface, a top surface hinged to the rear wall surface which has at least one top surface opening, at least one Closure system articulated on the cover surface, which has a support element articulated on the cover surface, a transmission element articulated on the support element and an actuator articulated on the transmission element igungselement comprises, wherein at least one locking lug on the transmission element is ausgebil det by a cutout from the support element, an outer front wall articulated to the bottom surface with at least one front wall side surface articulated to the outer front wall. With a blank designed in this way, there is a simple way of producing the paper-based container according to the invention from a one-piece body.
