3b: a partial cross section through the upper part of the container

Fig. 3a; FIGS. 1a to 2f show a first embodiment of the container. The container has a container body 1 and a

Container closure 2 on.

The container body 1 is tubular in the illustrated embodiment. It has a container wall 3, which forms a container space 4. In the container space 4, a packaged product, e.g. Tablets (not shown) can be arranged. The wall 3 forms a side wall 5 and a bottom 6. In the illustrated embodiment, the

Container body 1 has a substantially cylindrical shape with a

circular cross section (see, e.g., Fig. 1b). The container body 1 has an elongated shape. In FIGS. 1 b and 2 b, a container longitudinal axis 7 of the container body 1 is indicated.

The container body 1 has a container opening 8. This is surrounded by an edge 9 (see in particular Fig. 2a and 2b). The edge 9 has an inside and an outside. The inside and the outside are connected by an end face of the rim 9, which is the

End face 23 forms. In the illustrated container, the edge 9 is arranged in the extension of the side wall 5. The inner diameter of the container body 1 in the region of the rim 9 is substantially the same as the inner diameter of the container body 1 in the region of

Side wall 5. Accordingly, the container opening 8 extends over the entire container cross-section. To facilitate demolding is In this case, the inner diameter in the region of the edge 9 is slightly larger than the inner diameter in the region of the container body 1.

On the container body 1, a hinge 10 is provided, via which the container closure 2 is movably connected to the container body 1. The container closure 2 can therefore be moved repeatedly between the closed position shown in FIGS. 1a to 1c and the opened position shown in FIGS. 2a to 2f. The hinge 10 is formed as a film hinge. The hinge 10 has a section with reduced material thickness 1 1. The hinge 10 has a

Butterfly shape (see, e.g., Fig. 2a). As a result, the plastic material during opening and closing of the container closure 2 can be easily moved.

The container closure 2 closes the container opening 8 in the closed position. In the illustrated embodiment, the container closure 2 overlaps the edge 9. The container closure 2 has a base 12 and an apron 13 arranged thereon. The base is essentially flat. The apron 13 extends substantially perpendicular to the base 12. At the skirt 13, an actuating portion 14 arranged at right angles thereto is provided. The operating portion 14 is disposed on the hinge 10 opposite side. In a central region, the actuating portion 14 has a straight contour, which merges into a curved contour on both sides. The skirt 13 is arranged on the outer edge of the base 12. The

Apron 13 is formed circumferentially. The height of the apron, measured from the inside of the base 12, is between 10 and 20% of the

Inner diameter of the container closure 2. The skirt 13 has a first portion with a first apron height. The skirt 13 is provided in the region of the hinge 10 with a cutout 15 and has a second, lower skirt height in this area. The cutout 15 facilitates the closing of the container closure. 2 The container closure 2 is designed as a snap closure. In the closed position a positive connection between container closure 2 and container body 1 is achieved, the container closure 2 in the

closed position holds. For this purpose, at the edge 9 in a radial

Direction outwardly projecting portion 16 is provided. This is formed in the illustrated embodiment, characterized in that the edge 9 has on its outer side a circumferential groove extending in the circumferential direction. The outwardly projecting region 16 is arranged on the container closure 2 facing the end of the container body 1. On the skirt 13, a radially inwardly projecting portion 17 is provided. This engages in the closed position with the outwardly projecting portion 16. The inwardly projecting portion 17 has a peak 18. This is followed on a first, closer to the base 12 side of a first surface 19 at. On a second, farther from the base 12 side, adjoins the summit 18, a second surface 20 at. As shown, the first and the second surface opposite the container longitudinal axis 7 are inclined in opposite directions. In the illustrated embodiment, the angle of inclination between the first surface 19 and the container longitudinal axis 7 is between 175 ° and 140 °, preferably between 170 ° and 160 °. The angle of inclination between the second surface 20 and the container longitudinal axis is between 5 ° and 50 °, preferably between 10 ° and 30 °. As can be seen in particular from FIG. 2 b, the inwardly projecting region 17 has a substantially triangular shape in cross section. The first surface 19 and the second surface 20 are each formed cone-shaped. The peak 18 is formed by a radiused region connecting the first and second surfaces 19, 20.

The outwardly projecting portion 16 is not only the locking, but also allows a seal. This is on the

Container closure 2, a first sealing portion 30 is provided. This is arranged on the inside of the skirt 13 and is in the closed position on the outside of the edge 9, to a first seal to form. In this case, the seal is effected in particular by conditioning the first surface 19 at the edge 9. For better sealing, a cone-shaped sealing surface 21 is formed on the edge 9. This is formed by the outer contour of the outwardly projecting portion 17.

The container has a second seal, which is achieved by a second sealing portion 22. The second sealing portion 22 is disposed on the base. In this case, the second sealing portion 22 is located on the container body 1 side facing the base 12. The second sealing portion 22 is arranged so that it is in the closed position of

Container closure 2 rests against the end face 23 of the edge 9. The figures further show that the container has no sealing element which projects into the container opening 8 and rests against an inner side of the edge 9. This allows the container to be filled over its entire height.

The second sealing portion 22 is arranged in a recess. In the illustrated embodiment, the base 1 2 on one side of the second sealing portion 22 has a first groove 25 and on the other side a second groove 25 '. The grooves 25, 25 'are each formed circumferentially. The summit 24 does not protrude beyond a plane formed by the inside of the base 12. In particular, FIG. 2 d can be seen that a first boundary surface 26 is arranged on the summit 24 on a first side and a second boundary surface 26 'on a second side. The first and second boundary surfaces 26, 26 'are opposite to

Container longitudinal axis 7 inclined. The angle of inclination between the first

Boundary surface 26 and the container longitudinal axis 7 is between 10 ° and 60 °, preferably between 30 ° and 50 °. The angle of inclination between the second boundary surface 26 'and the container longitudinal axis 7 is between 10 ° and 60 °, preferably between 30 ° and 50 °. In essence, the second sealing portion 22 has a triangular shape in cross section. To achieve a good seal of the first sealing portion 30 is thereby biased to the edge 9, that the skirt 13 in the

closed position due to the contact with the edge 9 elastically deformed in the radial direction outwards. The elastic deformation path in the radial outward direction is between 0.25% and 2% of the inner diameter of the skirt 13. Preference is given to a deformation between 0.5% and 1% of the inner diameter of the skirt.

Furthermore, the skirt 13 and the base 12 are formed so that by the deformation of the skirt 13 in the closed position, the second

Sealing section 22 is biased against the end face 23. A deformation of the skirt 13 to the outside leads to a movement of the second

Sealing section 22 to the end face 23. In the illustrated embodiment, the end face 23 extends perpendicular to the container longitudinal axis 7. The end face 23 is formed flat. Alternatively, the end face can also be arranged inclined to the container longitudinal axis 7 to the outside. On the outside of the container body 1, a section 27 pointing outward from the wall 3 is provided below the edge 9. This is formed circumferentially. At the portion 27, the hinge 10 is arranged.

The container with the container body 1 and the container closure 2 is formed as a one-piece injection molded part. Accordingly, the entire container can be made cohesive in an injection mold.

Therefore, it is not necessary to subsequently mount a container closure on the container body. Rather, it is a one-piece injection molded part. In the illustrated container, the base 12 of the

Container closure 2 and the container body 1 of the same

Be injected plastic material. In the illustrated embodiment, moreover, the first sealing portion 30 and the second Sealing portion 22 made of the same plastic material as the base of the container closure.

FIGS. 3a and 3b show a further embodiment. This corresponds largely to the embodiment shown in FIGS. 1a to 2f. Parts of the same function are given the same reference numerals. Reference is made to the relevant description relating to FIGS. 1a to 2f, which applies to FIGS. 3a and 3b to this extent. Unlike the previous figures, however, is the second

Sealing portion 22 'not made of the same plastic material as the base 12. Figure 3b clearly shows that on the inside of the base 12, another material is arranged, which forms the second sealing portion 22 '. Such a container may be made, for example, by 2K injection molding.

In the illustrated example, the second sealing portion 22 'extends in layers over the entire inner side of the base 12.
