Storage or infusion bottle

Abstract

A storage or infusion bottle (1) has an integrally molded bottle neck (3) with a teat-shaped bottle feature (4, 5) projecting from its mouth end. The closed teat end wall (6, 7) of the bottle feature is puncturable by an infusion needle. A cap (8) is attachable to the bottle neck (3) and has a funnel-shaped cap feature (9, 10) with an interior space accommodating the free end region of the bottle feature (4, 5). The intermediate space between the end wall of the bottle feature (4, 5) and the opposing side of the cap feature (9, 10) is completely filled by a hat-shaped sealing element (11, 12) enclosing the bottle feature (4, 5) at least in its end region remote from the bottle (1).

(3) FIG. 2 is a top plan view of the storage bottle of FIG. 1, looking onto the cap located on the bottle neck of the bottle;

(4) FIG. 3 is a perspective view of the storage bottle of FIGS. 1 and 2;

(5) FIG. 4 is a side view in section of the storage bottle of FIGS. 1 to 3 taken along the plane A-A according to FIG. 2; and

(6) FIG. 5 is a perspective view in section of the storage bottle of FIGS. 1 to 4 taken along the plane B-B according to FIG. 2.

DETAILED DESCRIPTION OF THE INVENTION

(7) FIGS. 1 to 5 illustrate a storage or infusion bottle 1 in the region of its bottle neck 3 that bears a cap 8. The storage bottle 1 is embodied as a blow-fill-seal bottle, in which the content of the bottle is enclosed in a sealed and sterile manner on all sides by the one-piece walling or wall of the bottle. The storage bottle 1 also has a closed bottle walling at the end wall of its bottle neck 3. At least one bottle feature or projection 4, 5 is teat-shaped and smaller than the cross section of the mouth end of the bottle neck and projects from the mouth end of bottle neck teat 3. The closed teat end wall of the bottle feature is designed to be puncturable by an infusion needle. A cap 8 is attachable to the bottle neck 3, onto which cap the usual infusion equipment or similar extraction equipment is mountable. This cap 8 has at least one funnel-shaped cap feature or projection 9, 10, with its feature interior space accommodating at least the free end region of the corresponding bottle feature 4, 5. A hat-shaped sealing element 11, 12 completely fills the intermediate space between the end wall 6, 7 of the at least one bottle feature 4, 5 and the opposing side of the corresponding cap feature 9, 10. The sealing element 11, 12 encloses the bottle feature 4, 5 at least in its end region facing away from the storage bottle 1. This sealing element 11, 12 is held at the circumference of its hat shape in a form-fitting and/or force-fitting manner on the circumference of the bottle feature 4, 5. Since the sealing element 11, 12 completely fills the intermediate space between the end wall of the bottle feature 4, 5 and the opposing side of the corresponding cap feature 9, 10, an intermediate space is avoided.

(8) As clearly evident in the longitudinal sections according to FIGS. 4 and 5, the storage bottle 1 has two teat-shaped bottle features 4, 5 on the mouth end of its bottle neck 3. Each of these bottle features 4, 5 projects into a funnel-shaped cap feature 9, 10. In each case one hat-shaped sealing element is provided and preferably held by bonding in every cap feature 9, 10. The sealing element 11, 12 densely encloses the corresponding bottle feature 4, 5 such that the intermediate space between the cap feature 9, 10 and the bottle feature 4, 5 is completely filled and free of dead space.

(9) Since the bottle content is extracted via the teat-shaped bottle feature 4, 5, since the bottle feature 4, 5 has a smaller diameter or cross section as compared to the end wall forming the base of the bottle neck 3, and since during piercing of the end wall of the bottle feature 4, 5 this end wall, which is relatively small in cross section, is less prone to distortion. The forming of an undesirable dead space is also not to be expected during piercing by the infusion needle. Since the sealing element 11, 12 with its hat shape encloses the bottle feature 4, 5 at least in its end region facing away from the storage or infusion bottle 1 and is held at its internal circumference in a form-fitting and/or force-fitting manner on the circumference of the bottle feature 4, 5, a relatively large amount of leaking fluid cannot run or flow out from the bottle opening punctured by the infusion needle. In this way, in the case of the storage bottle 1 illustrated, a complete extraction of the fluid stored therein, and thus, a correct dosing can be ensured.

(10) As well recognizable in FIG. 4, the hat-shaped sealing elements 11, 12 are each held on the corresponding bottle feature 4, 5 by a latching connection. For this purpose, every sealing element 11, 12 has on the interior circumference of its hat shape a latching projection 13 that interacts with a corresponding latching groove 14 on the outer circumference of the corresponding bottle feature 4, 5.

(11) A comparison between the FIGS. 2, 3 and 5 elucidates that each of the funnel-shaped cap features 9, 10 has a puncture opening 15, 16. Not shown here is that these puncture openings 15, 16 may each be closed by a tear-away or tear-off cover element or cover.

(12) A comparison between the FIGS. 4 and 5 shows that an annular flange 17 projects from the bottle neck 3 of the storage bottle 1. The cap 8, which is approximately dome-shaped, is attachable to the bottle neck 3 of the storage bottle 1 at the point at which the margin of the cap circumference 18, which here is folded around in the shape of an edge of a plate, lies on the annular flange 17. To captively connect the cap 8 with the storage bottle 1, the margin of the cap circumference 18 may be non-detachably connected to the annular flange 17 by welding or the like.

(13) While one embodiment has been chosen to illustrate the invention, it will be understood by those skilled in the art that various changes and modifications can be made therein without departing from the scope of the invention as defined in the claims.
