Description

The invention relates to a feeding bottle for infants and toddlers.

Nutritional bottles (also called "baby bottles") are vessels for nourishing a child by means of a nourishing teat (also called a "teat") or a drinking aid (eg a nipple or drinking spout). Nutritional vials are preferably graduated for visual metering and picking up a liquid. Nutritional bottles, feeding teat and drinking aids are the subject of European standard EN14350-1.

Nutritional bottles are made of plastic and glass. Glass vials are durable, hygienic, environmentally friendly and easy to clean. Multi-use glass vials are made of borosilicate glass.

Known baby bottles made of glass have a long threaded neck with an external thread for screwing on a mounting ring for a food teat. Below the thread profile runs on the threaded neck an outwardly projecting annular bead. The annular bead is used to attach a gripper in the manufacture of the glass bottle. The tightening of the fastening ring is limited by the annular bead. The torus can be easily damaged during manufacture or use. The threaded neck sits on a bottle shoulder, whose diameter gradually increases downwards and is connected at the bottom over a large radius with the bottle body. In a known embodiment, the angle of the bottle shoulder to the horizontal above the radius is 55 ° and the radius in the transition to the bottle body 15 mm. The bottle shoulder requires a corresponding use of material and leads to a corresponding total length of the feeding bottle.

Single use glass baby bottles are especially for clinics. They are made of soda lime glass and are not as strong as baby glass bottles for multiple use. A known disposable baby soda bottle made of soda-lime glass has a groove below the threaded neck for attaching a gripper during production. This is followed by a bottleneck over a large inner radius (5 mm), which runs down over an even larger outer radius (23.5 mm) towards the body of the bottle. The long bottle shoulder with gradually widening diameter requires a high material usage and a large length of the baby bottle.

In all known food bottles gapes a large gap between the mounting ring and bottle body, which facilitates the ingress of dirt and disturbs the feel and appearance.

On this basis, the present invention seeks to provide a glass jar, which is less susceptible to damage, allows for shorter design with less material and allows improved feel and an improved appearance.

The object is achieved by a nutritional vial with the features of claim 1. Advantageous embodiments of the feeding bottle are specified in subclaims.

The glass feeding vial according to the invention comprises a bottle body which has a bottle bottom at the bottom and is connected at the top by a bottle shoulder with an upwardly projecting threaded neck, wherein the threaded neck forms the top as a circular cylindrical hollow body is, on which an outwardly projecting thread profile of an external thread rotates and the threaded neck down has a circumferential annular groove which is bounded above by the lower end side of the hollow body and below by the bottle shoulder and between bottle shoulder and bottle body an outer radius of 7.5 mm is available.

In the case of the feeding bottle according to the invention, instead of the annular bead below the external thread, there is a circumferential annular groove into which a gripper for moving the bottle during production can intervene. Thus, damage to a torus is avoided. Further, the threaded neck can be made shorter than conventional glass jars, so that the screw ring can be screwed close to the bottle shoulder. In addition, the radius of maximum 7.5 mm between the bottle shoulder and the bottle body allows very short or almost square bottle shoulders. As a result, a gap between the screw ring and the bottle body can be greatly reduced, whereby the penetration of impurities can be avoided and the feel and external appearance of the feeding bottle can be improved.
