Description

[0059] The invention is explained in more detail using the figures. It shows

[0060] FIG. 1 a glass bottle without decorative element perspective view and in longitudinal section,

[0061] FIG. 2 an embodiment of a glass bottle according to the invention in longitudinal section, and

[0062] FIG. 3 another embodiment of a glass bottle according to the invention before assembly.

[0063] FIG. 1a shows a glass bottle 1 without inserted decorative element in a perspective view. The glass bottle 1 has a glass hollow body 2 and a bottom insert 3. The bottom insert 3 is designed in 2 parts, with the inner part engaging in the glass hollow body and the outer part being positioned as a ring around the glass bottom. FIG. 1b shows a longitudinal section through the glass bottle 1 from FIG. 1a. The bottom insert 3 has 2 radial grooves 16, with one sealing ring 11 located in each. The lower outer edge of the glass hollow body 2 is ground so that a step-shaped recess 12 is formed on the outside of the glass hollow body. Adhesive is applied to the vertical surface of the step-shaped recess 12 so that the vertical surface forms a radial adhesive surface 19.

[0064] FIG. 2a shows a longitudinal section through an embodiment of a glass bottle 1 according to the invention. The glass bottle 1 has a glass hollow body 2 with an opening 6 in the bottle bottom 8. The bottle bottom has a bottom rim 9 which surrounds the opening in a circular manner. The opening 6 is closed by the bottom insert 3. The bottom insert 3 is designed as a disc and has an outer circumferential edge 10. The bottom insert 3 is surrounded by a sealing ring 11 which seals the gap between the bottom insert and the glass hollow body in the opening. The bottom insert 3 has a mounting fixture 7, which is designed here as a thread. A three-dimensional decorative element 4, which is a rocker arm here, is attached to the mounting fixture. The rocker arm has a thread at its lower end, with which it is screwed to the mounting fixture. It can be seen that the rocker arm is located in the interior 5 of the glass bottle.

[0065] FIG. 2b shows an enlarged section of a portion of the bottle bottom 8. It can be seen that the glass bottom rim 9 has a step-shaped recess 12 on its underside. The horizontal surface of the step forms a supporting surface 13, to which adhesive can be applied. The outer circumferential edge 10 of the bottom insert 3 rests with its upper side 18 against the stop surface 13. The bottom insert 3 also has a step-shaped recess. The higher step of the bottom insert rests against the stop surface 13, and a small cavity can be seen between the lower step of the step-shaped recess and glass bottom rim 9, which is filled by the adhesive when the two elements are brought together. The two surfaces are attached using adhesive so that axial bonding occurs. In this embodiment, the bottom insert 3 has 2 radial grooves 16, which serve to receive the sealant 11, which are designed as an O-ring here.

[0066] FIG. 2c shows another enlarged section of another part of the bottle bottom 8. The bottom insert 3 is formed as a disc with a cavity 14 here. The center of the bottom insert 3 comprises a hexagon 15 which has an internal thread in its interior. The lower end of the three-dimensional decorative element 4 has an external thread which is screwed into the internal thread inside the hexagon 15.

[0067] FIG. 2d shows a top view of the bottle bottom 8 of the glass bottle from FIG. 2a. The outer edge of the bottle bottom 8 is formed by part of the glass hollow body in the form of the glass bottom rim 9. The bottom insert 3 is inserted into the glass bottle. Hexagon 15 can be seen in the center of the bottom insert 3. There is a cavity 14 between the outer circumferential edge 10 of the bottom insert and the hexagon 15.

[0068] FIG. 3a shows a further embodiment of a glass bottle 1 according to the invention in longitudinal section. The individual components of the glass bottle are not yet attached to each other here. The left-hand side shows the glass hollow body 2, which has an opening 6 bottle bottom 8. The glass hollow body 2 forms a glass bottom rim 9, which is part of the bottle bottom 8. The underside of the glass bottom rim 9 has a step-shaped recess 12. The right-hand side shows bottom insert 3 with mounting fixture 7 firmly mounted on it. The bottom insert 3 and the mounting fixture 7 are made in one piece here. The underside of bottom insert 3 has an outer circumferential edge 10. The bottom insert is hollowed out on its underside and has a cavity 14. On its vertical side wall, the bottom insert 2 has outer radial grooves 16 which serve to mount a sealing ring 11. A three-dimensional decorative element 4 is shown above the bottom insert 3. This has a bore 17 on its underside with which it is attached to the mounting fixture 7.

[0069] FIG. 3b shows a section of the lower area of the glass bottle from FIG. 3a after assembly. It can be seen that the bottom insert 3 closes the opening 6 in the glass hollow body 2. The sealing rings 11 are thereby clamped between the edge of the bottom insert and the edge of the opening 6, thus sealing the bottom. The supporting surface 13 rests on the outer circumferential edge 10 of the bottom insert, with the two being attached to each other using adhesive.
