Definitions

• Paper or cardboard blanks for the production of bottle-like objects of the type mentioned above are known in a large number.
• CA 210195 A1 already a cardboard bottle whose body and neck are made from a single piece.
• a separately formed base element is connected to the bottle body.
• U A blank made of paper or cardboard for producing a bottle-like object is known, which comprises a sequence of individual, differently shaped neck tabs for forming a bottle neck.
• US 1 100 448 A discloses a blank for producing a bottle from paper, wherein the blank has a plurality of identically formed neck tabs for forming a bottle neck.
• a disadvantage of these known blanks is that automated, machine-based production of such bottles is only possible with considerable mechanical effort due to the design of the known blanks, particularly the neck tabs required to form the bottle neck. Furthermore, carton bottles formed from these known blanks often develop leaks in the bottle neck area.
• a first aspect of the invention relates to a blank made of paper or cardboard for producing a bottle-like object, comprising a tab portion for forming a bottle neck and a body portion for forming a bottle body.
• the tab portion is arranged at one end of the body portion.
• the tab portion comprises a sequence of a group of first neck tabs and a group of second neck tabs, wherein the first and second neck tabs are differently designed such that at least one region of the respective first neck tab, in the assembled state of the blank, rests on at least one corresponding adhesive and/or bonding portion of the respective second neck tab.
• a length A of the second neck tab is greater than or equal to a length B of the first neck tab, wherein the lengths A and B are measured starting from the body portion. This ensures that the second neck tabs have a sufficiently large support surface over their length A for the first neck tabs along their length B. This contributes to the tightness of the bottle-like object produced from the blank in the region of the bottle neck thus formed.
• the first neck tab has a tab body which, in a region closer to the body section, is wider transversely to its longitudinal extent than at a tab end facing away from the body section
• the second neck tab has a tab body, wherein the tab body is wider transversely to its longitudinal extent in a region closer to the body section than at a tab end facing away from the body section.
• At least one crease line to be formed in the tab body of the first neck tab in the longitudinal extension of the first neck tab and/or for at least one crease line to be formed in the tab body of the second neck tab in the longitudinal extension of the second neck tab.
• the crease lines advantageously contribute to the stability of the respective neck tab. Furthermore, they contribute to better formability of the individual tabs.
• the crease line which is formed in a wide region of the tab body of the second neck tab close to the body section, to limit the expansion of the adhesive and/or bonding section in the second neck tab. This results in improved formability of the tab body of the second neck tab in the region of the adhesive and/or bonding section.
• a length of the body section in the direction of the tab section and in the region of the first neck tabs is greater than or equal to a length of the body section in the direction of the tab section and in the region of the second neck tabs.
• the body section can be designed in a stepped manner in a transition region between the first group of first neck tabs and the group of second neck tabs.
• a second aspect of the invention relates to a bottle-like article made of paper or cardboard, wherein the article is produced from a blank according to the first aspect of the invention.
• the bottle-like article according to the invention is simple and cost-effective to produce and is characterized in particular by its improved tightness.
• a fourth aspect of the invention relates to a bottle comprising a bottle-like object according to the second aspect of the invention, wherein the bottle has at least one base element for closing the bottle-like object at the base and/or at least one closure element for releasably closing the bottle-like object at the bottle neck and/or at least one spout at the bottle neck and/or a bag-like element for receiving a liquid within the bottle body.
• a bottle is simple and cost-effective to produce and, in particular, has improved tightness.
• the Figure 1 shows a schematic representation of a blank 10 according to a first embodiment.
• the blank 10 is made of paper or cardboard. and is used to produce a bottle-like object 20 (see also Fig. 5 ).
• cardboard types with a grammage between 200 and 600 g/m 2 , especially between 250 and 350 g/m 2 , are used.
• the thickness of the cardboard used can be 0.5 mm ⁇ 0.2 mm. Other grammages and thicknesses are also conceivable.
• the tab section 12 comprises an equal number of first and second neck tabs 22, 24.
• the first and second neck tabs 22, 24 are arranged in groups and one behind the other.
• These adhesive and/or bonding sections 26 are each delimited by a crease line 44 formed in the wider region of the tab body 34 and close to the body portion 14. Furthermore, it can be seen that additional crease lines 42, 46 are formed in the tab bodies 30 and 34. These crease lines 42, 44, 46 serve, on the one hand, to increase the stability of the neck tabs 22, 24 and, on the other hand, to facilitate the formability of these tabs 22, 24.
• Fig. 4 shows a schematic representation of a blank 10 according to a second embodiment.
• the first and second neck tabs 22, 24 have a different shape than in the first embodiment.
• the respective tab bodies 30 are also wider in the areas closer to the body portion 14 than at the corresponding tab ends 32.
• additional creasing lines 40 are provided in these areas. formed. These creasing lines 40 also serve, on the one hand, to increase the stability of the first neck tabs 22 in the aforementioned areas and, on the other hand, to improve formability.
• the creasing lines 44, 46, which are formed in the respective tab bodies 34 of the second neck tabs 24, also have a different arrangement and a different design than the corresponding creasing lines of the first exemplary embodiment.
• the blank 10 according to the second exemplary embodiment again has a flanged tab 48.
• Fig. 5 shows a schematic representation of a blank made according to Fig. 1 manufactured bottle-like object 20.
• the creasing lines of the blank 10 have not been taken into account.
• the body section 14 has been formed into the bottle body 16.
• the bottle body 16 is followed by the bottle neck 18, which was formed from the tab section 12.
• the first and second neck tabs 22, 24 have been connected to one another and, in particular, glued and pressed.
• the bottle-like object 20 has a base element 50.
• the base element 50 is in Fig. 6 shown schematically. The round design of the base element 50 and the adhesive tabs 52 arranged around the circumference of the base element 50 can be seen.
• the blank 10 and consequently also the bottle-like object 20 produced therefrom can be at least partially coated.
• This can be a protective coating that has a water- and/or grease-repellent effect, for example.
