DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a baby bottle having a neck with a mouth and a nipple with a horizontal flange, which is supported by an annular cap detachably connectable to the neck, is placed on the face end of the mouth, and can be sealed off from the mouth of the bottle.
2. Description of Prior Art
In conventional baby bottles of this generic type, the connection between the nipple and the bottle can be made with a threaded annular cap. For refilling the baby bottle, the annular cap must be detached from the body of the bottle and set aside. This involves a disadvantage that the nipple will get dirty or drop on the floor. If several bottles are refilled at the same time, as a is the case in hospitals, then there is the further disadvantage that the various nipples will be reassemble on the wrong bottles.
SUMMARY OF THE INVENTION
Based on the above prior art, it is the object of the invention to improve a baby bottle of the type described above in such a way that, without entailing disproportionate engineering expense, is an undetachable connection between the baby bottle and the nipple even when the bottle is to be refilled.
This object is attained in accordance with the invention with an annular cap pivotally attached to the neck and connectable with it in such a way that it is pivotal out of its active operational position in which the flange of the nipple pressure against the face end of the mouth into one of its passive operational positions. The nipple is disposed laterally of the face end of the mouth or laterally of the neck, leaving the mouth free.
The invention is achieved whenever the annular cap carrying the nipple is connectable to the neck in such a way that first, it can connect the nipple to the baby bottle in the manner typical for the conventional threaded annular caps, and second, it establishes a connection between the baby bottle and the nipple even when the nipple is not connected compressively to the mouth.
Further practical and advantageous features of the invention are defined by the dependent claims.
A particularly advantageous feature of the invention is that the annular cap is carried by a retaining body detachably connectable to the neck and is connected to this retaining body via a joint. It is advantageous if the retaining body is an approximately fork-shaped connecting piece that can be snapped into place onto the neck and has legs that extend over more than 180.degree. of the circumference of the neck. In this embodiment of the invention, the actual connection between the annular cap and the neck of the bottle is established with a retaining body that is detachably connected through a detent connection, to the neck.
In another practical embodiment of the invention provides that the annular cap is a portion of a hollow cylinder having a radially inwardly oriented flange that presses the flange of the nipple against the face end of the mouth. If the side of the annular cap diametrically opposed to the joint, which in particular is a hinge, has an inwardly oriented detent protrusion that is detachably connectable to a detent recess of the neck, then the annular cap is essentially a conventional annular cap but has no internal thread. Instead, it is a hollow-cylindrical portion that can be snapped into place on the end piece of the neck. If the baby bottle is refilled, then the annular cap can be actuated in the vicinity of its detent protrusion, releasing this detent connection, and the annular cap then pivots about the hinge.
In a baby bottle having a cup-shaped cover cap that receives the nipple and is detachably connectable to the neck, such as a sealing cap or guard, it is practical for the cover cap to have at least one protrusion on the inside protruding toward the annular cap. In the active state of the cover cap, this protrusion is compressively connected to the side of the annular cap remote from the face end of the mouth. Good, uniform distribution of pressure is attainable for instance when the protrusion is cyl
