CONTAINER WITH A SECURING DEVICE

Abstract

The invention relates to a container with a securing device (16), in particular in the form of a blow-molded plastic container, preferably in the form of an ampoule, comprising a storage part (4) for receiving a medium which can be dispensed via a container opening (10) and comprising a head part (6) which is removably connected to the storage part (4) via a separation point (12) and which releases the container opening (10) for a removal process of the medium after the head part has been separated from the storage part (4). The invention is characterized in that the separation of the head part (6) from the storage part (4) is completely prevented or at least hindered by means of the securing device (16) in a securing position, and the head part (6) can be removed from the storage part (4) without force via the separation point (12) in at least one release position.

Description

[0017] The container with a safety device according to the invention is explained in greater detail below with reference to various exemplary embodiments according to the drawings.

[0018] In the drawings, depicted schematically and not to scale,

[0019] FIGS. 1 to 3 show in a front view, in a side view and in a top view, a multiblock made up of several container units according to the invention;

[0020] FIGS. 4 to 8 show in different actuation positions, the safety device for the container according to FIGS. 1 to 3, for the sake of simpler depiction, only the upper part of the container solution being depicted without the actual container body forming the storage part.

[0021] The invention is explained in greater detail below with reference to an exemplary embodiment according to FIGS. 1 to 7, in which the safety device in the form of a child safety feature complicates the opening process for plastic containers in ampoule form made from blow-molded plastic. Such ampoules can be produced in one piece, filled in a sterile manner and sealed using the bottelpack method, for example. Such ampoules or containers can be marketed collectively as a so-called multiblock, particularly preferably as a unit consisting of several ampoules. In FIGS. 1 to 3, a multiblock with six ampoules joined at separation points 2 is in each case identified as a whole with the reference numeral 1. Each ampoule or container has, viewed in cross-section, a polygonal storage part 4 (FIG. 3) with an upper head part 6, which extends in the direction of a container opening 10, while forming a conical narrowing or tapering in the form of a neck part 8. As can be seen in particular from FIGS. 4 to 8, the head part 6 is releasably connected, by means of a separation point 12 of the predetermined breaking point type, to the neck part 8, which surrounds the container opening 10 at this point. The head part 6 can be separated or sheared off (twist-off-cap) from the front upper end of the head part 6 by means of a manipulation part 14. After separation of the head part 6, the container opening 10 is released accordingly and a dispensable medium can be removed from the storage part 4 via the container opening 10.

[0022] Furthermore, the container solution according to the invention is equipped with a safety device identified as a whole with the reference numeral 16 which, in a safety depiction according to the drawings of FIGS. 1 to 3 and 4, completely prevents or at least complicates the separation of the head part 6 from the storage part 4 with the neck part 8. Due to the assumed safety position, it is not possible to manually twist off the head part 6 via the separation point 12 and to remove it in the upwards direction as viewed in the viewing direction of the figures. In at least one release position however, as is depicted in FIGS. 5 to 8, the head part 6 can be easily removed from the storage part 4 via the separation point 12, with the head part 6 still being depicted in its sealed position according to FIGS. 5 and 6, and in FIGS. 7 and 8, the container opening 10 is released and the head part 6 is already removed.

[0023] The safety device 16 has a securing bracket 18 which, in the depicted safety position, at least partially spans the head part 6 in the manner of a bracket along its free outer circumference, with the securing bracket 18 assuming in its respective release position a pivot position opposite the storage part 4, which release position releases the head part 6 for an actuation, in particular, for its removal from the storage part 4. This folded back release position is reproduced in FIGS. 5 to 8.

[0024] The securing bracket 18 is pivotably linked to the storage part at its two ends facing the storage part 4 by means of linkage points 20. Said linkage points 20 abut a frame 22 of the storage part 4, which defines a midplane 24 for the container and the wall thickness of which (cf. FIG. 2) is selected thinner than the wall thickness for the securing bracket 18.

[0025] As is seen in particular from FIG. 4, the two linkage points 20 are disposed diametral to a longitudinal or vertical axis 26 of the container and they are formed as trunnions (cf. FIG. 8). In addition, the respective linkage point 20 is disposed in an area of the container in which a cylindrical part of the neck part 8 transitions into a conical taper of the neck part, which ends at the container opening 10 (cf. FIGS. 5 and 6).

[0026] The free pivot path of the securing bracket 18, from the zero position, relative to the longitudinal or vertical axis 26 of the container, which corresponds to the safety position, into an unlocked position, which corresponds to the release position, can vary by at least 90. The pivot position is preferably larger, however, and the securing bracket 18 can be pivoted back until it abuts at least with its upper end the upper side of container wall parts of the storage part 4. According to the depiction of FIGS. 5 to 8, the securing bracket 18 is, for the sake of simpler depiction, pivoted away from the longitudinal or vertical axis 26 of the container by approximately 30.

[0027] As can also be seen from FIG. 4, the securing bracket 18 is, in its locked safety position depicted therein, releasably fixed along the outer contour of the head part 6 and of the conically tapered neck part 8 by means of two connection parts 28, which form a type of predetermined breaking point. The securing bracket 18 thus forms with its outer contour in the safety position a partial frame in the manner of a card part 30, which then at least partially also surrounds the storage part 4 in the area of the neck part 8. This solution requires punching the plastic material in this area, with the punching then excluding the connection parts 28, by means of which the securing bracket 18 can be separated from the head part 6 in a predetermined breaking point manner.

[0028] Another option is to provide a reduction of the wall thickness in the plastic material along the depicted separation line between head part 6 and the neck part 8 and the card part 30 of the securing bracket 18 which, when manually perforated, can then release the securing bracket 18. As the depiction according to FIG. 1 shows, these card parts 30 of neighboring containers abut one another and form, together with the aforementioned separation points 2, two continuous separation areas, to allow individual containers to be appropriately separated from the multiblock arrangement according to FIG. 1. Such separation points 2 within the multiblock arrangement 1 likewise delimit frames 22, from which the storage part 4 with a pre-determinable storage volume then projects.

[0029] A method for releasing the container opening 10, which is provided in a container with a safety device 16, then proceeds as follows. Firstly, the securing bracket 18 of the safety device 16, after tearing through the connection parts 28, is pivoted out of its safety position and so far away from the head part 6 and the neck part 8 that, by means of the manipulation part 14, the head part 6 is twisted away from the separation point 12 by a user. The container opening 10 is thus then released (cf. FIG. 8) and, to ensure an interference-free removal process, the securing bracket 18 of the safety device 16 is manually pivoted back to an appropriate extent.
