Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement in the shape of a Gebert top type paper container.

[Conventional technology]

FIG. 4 shows a conventional Goebelt top type paper container, and FIG. 5 is a developed view of the blank plate of the paper container shown in FIG.

In the conventional product, the end board 34 is connected to the pair of roof boards 31 and 32 via the folding board 33, and when the blank board is assembled into the container, the end board 34 is attached to the body board 3.
It enters between a pair of roof plates 31 and 32 diagonally with respect to 5.

[The problem that the idea attempts to solve]

When filling any type of container with its contents, if the contents are foamy, the seal will not seal properly, often leading to accidents. Various filling machines have been devised to minimize foaming of the contents, but as the filling speed increases, it often becomes difficult to suppress foaming. In particular, in Goebelt top-type paper containers, the end plate is folded inward between the roof plates and diagonally to the body plate, so the volume of the head space is significantly reduced, and the bubbles that have accumulated in the head space overflow from the top. It often happens. In addition, in the top seal section of the filling machine for Gebert top paper containers, the container is moved while closing the top section, so the vibrations cause the contents to ripple inside the container and often adhere to the top seal section, which also causes seal failure. This was one of the causes.

[Means for solving the problems]

In a Goebert-type paper container, one of the two end boards is on the same plane as the body board connected to the end board, and two folding boards are connected via a center fold line and folded into the inside of the container. The two folded plates have a triangular shape that is symmetrical about the center fold line, and have a folded seal portion on the side that is not connected to the end plate or the roof plate. are arranged in series, and the folded seal portion is folded in and bonded between the upper parts of the opposing roof plates.

〔Example〕

FIG. 1 shows an embodiment of the paper container of the present invention, and FIG. 2 shows a blank plate for the paper container shown in FIG.

In the paper container formed using this blank board, only one end plate is on the same plane as the body plate, and the other end plate is inclined with respect to the body plate. That is, the gable board 3
4 are connected in series, and two folding plates 36 and 37 are connected to this end plate 34 via a center fold line 5, and when assembled into a container, 1
The body plate 35 and the end plate 34 are on the same plane.

The other end board 34 is connected to the body board 35 via the ruled line 20', and this end board 34 has a center fold line 20.
Two folding plates 33 are connected to each other via 2 and 23.

The blank board shown in the second figure has the margin part b as the edge line a.
1, 2, 3, 4, 11, 14, 15, 18, 1.
8', 19, 19', 20, 20', 20'', 24,
Mountain fold 25, ruled lines 5, 6, 7, 9, 12, 1
Valley fold 3, 21, 21″, 22, 23, 26,
By folding the folding plates 36, 37 and the folding plate 33 into the container, the paper container shown in the first figure can be formed. In the blank plate shown in the second figure, line segment AC=AB=DE=DB, line segments AF and DG are the bisectors of angle CAB and angle EDB, respectively, and angle AFI=
Angle AFH = Angle DGH = Angle DGJ, and ruled line 11 is a line segment
It is perpendicular to AD, ruled lines 14, 15 and ruled line 20 are parallel, and line segments AF and DG are at point F, when assembled.
The length should be such that G does not protrude beyond the top seal.
The rest is the same as the Goebelt top type paper container shown in FIGS. 4 and 5.

FIG. 3 schematically shows the head space portion seen in a cut plane perpendicular to the bottom surface passing through the top seal portion of this embodiment, and the hatched portion 38 indicates the head space portion.

FIG. 6 schematically shows a head space section seen in a cut plane perpendicular to the bottom surface passing through the top seal section of a conventional product, and the hatched section indicates the head space section 40.

[Effect of idea]

As described in detail above, according to the present invention, the head space can be increased and sealing defects can be eliminated.

According to the present invention, if the carton sizes are the same,
The amount of head space in the top section is calculated to be 25% more than the conventional product. Although the present invention does not fundamentally solve the problem of top seal failure of Gebelt-tipped paper containers due to bubbles and ripples, the filling speed is This is effective when trying to increase the foaming properties or when foaming properties have increased due to changes in the physical properties of the contents.
