Definitions

• the invention relates to a suction bottle with a bottle body with a wide bottle neck, on which a teat with a diameter that is small compared to the bottle neck can be attached or attached with the aid of a cap, in particular a screw cap like a union nut, the cap having a central opening for the teat.
• Numerous suction bottles are known (see, for example, GB-PS 1 027 101, US-A-2 959 314, US-A-3 495 993 and FR-A-2 446 632), which in the usual way have a relatively narrow bottle body or have at least a narrow bottle neck to which a teat is attached to use the bottle. It is also known to insert disc-like valve elements between the bottle neck and the teat in order to avoid sucking in air (GB-PS 1 027 101, US-A-2 959 314 and FR-A-2 446 632). From US-A-3 495 993 such a "narrow neck" suction bottle is also known, in which a hermetically sealing cap is provided between the teat and the bottle neck, which must be pressed in before the bottle is used.
• Such a wide-mouth bottle is known from EP-A-9460, in which the teat is attached in a conventional manner by means of a screw cap on the upper neck edge of the bottle.
• the teat is clamped against the upper edge of the bottle neck with a radial flange, but the clamping area is only very narrow.
• the teat can be easily pushed into the inside of the bottle or pulled out of its clamp holder, even by the baby, and consequently there is a risk of the baby being swallowed and suffocated.
• suction bottle Another disadvantage of this known suction bottle is that appropriately large suction cups with a wide base corresponding to the bottle neck must be used, the suction material currently preferred for hygienic and processing reasons, namely silicone rubber, being relatively expensive, so that the costs for the Suction cups get very high. Since different liquid foods, such as milk, tea, porridge, etc., are usually administered with one and the same feeding bottle, a supply of suckers with differently sized outlet openings must be kept, just as it is expedient to reserve a range of suckers in reserve hold. With such storage of suction devices, however, the above-mentioned high costs for the relatively large suction devices are all the more significant.
• the silicone rubber suction cup is to be permanently anchored in the opening of the screw cap made of thermoplastic material by means of an injection molding process. If the suction cup has to be replaced in this suction bottle, the unit suction cup screw cap must always be exchanged, just as such units must be kept in stock, which is uneconomical and moreover takes up a relatively large amount of space.
• the aim of the invention is to remedy this and to enable the use of comparatively small suction cups. which can nonetheless be securely anchored to the wide bottle neck.
• the suction bottle according to the invention of the type mentioned at the outset is characterized by an essentially rigid adapter ring between the bottle neck and the teat or cap, the upper side of the adapter ring forming a flat counter-clamp for the cap and the teat or its lower, radial flange.
• the outlet diameter is reduced to a smaller dimension than the diameter of the wide bottle neck, this reduced outlet diameter appropriately corresponding to the diameter of the commercially available suction cups for narrow suction bottles.
• the adapter ring can provide a relatively wide, annular clamping surface for the suction flange, so that it is also possible to use commercially available suction cups with varying diameters and nonetheless to securely clamp them between the adapter ring and the cap.
• the cap can be tightened to the bottle by means of a screw thread or a bayonet lock.
• the advantage is also achieved that the suction cup is held securely over its suction flange despite a smaller surface pressure, which is gentle on the material. As mentioned, this secure clamping is not impaired even when suction cups with slightly different dimensions are used.
• the use of smaller suction cups results in lower material and cost, so that the above-mentioned storage is favored.
• the adapter ring which can also be called a reducer, can be made of much cheaper plastic material, in contrast to the teat, which is preferably made of silicone rubber, and it is only needed once for a bottle.
• a baby milk bottle with an opening and removal cap is known from EP-A-137 458, with a cylindrical one on the upper edge of the bottle Stop element with the same outer diameter as the bottle neck can be attached.
• a suction cup is then clamped to the top of this cylindrical stop element by means of a screw cap which is screwed onto the cylindrical stop element and then screwed to the bottle neck.
• the suction cup has a lower radial flange with a diameter approximately equal to the - narrow - bottle neck.
• the cylindrical stop element has a flange-like raised opening edge at the top, around which the suction cup with its lower edge is clamped around the outside.
• this known design is only suitable for the use of a predetermined suction device having certain dimensions.
• this cylindrical stop element is intended to open a bottle cap provided for sterile use with profile elements present in its interior by means of an attachment formed thereon and a predetermined breaking point.
• the adapter ring i.e. more specifically its top, e.g. be domed or have a truncated cone shape, the cap advantageously being designed with its upper wall on the inside accordingly.
• the upper side of the adapter ring is flat, at least in the inner region adjoining the ring opening.
• the cap is correspondingly flat.
• This flat design also takes into account the fact that a horizontal radial suction flange is provided in most commercially available suction cups, which can thus be clamped particularly gently and securely between the two flat clamping surfaces while exerting a uniform pressure.
• At least one of the inner ring opening in the top of the adapter ring Circumferential edge leading ventilation groove is attached.
• two diametrically opposite, radially extending ventilation grooves are provided.
• Ventilations grooves which can have a width of 1 - 2 mm and a depth of 0.5 - 1 mm, for example, do not hinder the inflow of air, even if the suction flange is firmly clamped against the top of the adapter ring, but they provide a sufficient level great flow resistance for the liquid food contained in the bottle, especially if it is of a pulp-like consistency, so that its - undesirable - leakage is effectively prevented.
• the inner opening of the adapter ring has a diameter which is at least substantially equal to the diameter of the central opening in the cap.
• the adapter ring has a downwardly projecting axial flange with which it fits into the bottle neck opening, for example in a press fit. It is also advantageous if the adapter ring has a radially extending stop, for example in the form of a circumferential collar, with which it rests on the top of the bottle neck in the position of use. In itself, however, it would also be conceivable, instead of a circumferential flange-like collar, to provide a plurality of nub-like projections distributed over the circumference on the outside of the adapter ring.
• a particularly simple design can be obtained in that the adapter ring is formed by a flat washer.
• the ring-shaped counter-clamping surface of the adapter ring can preferably be made flat, but, if desired, can also be frustoconical or dome-shaped. In all of these cases, however, it has proven particularly advantageous to uniformly clamp the suction flange proven if the annular counter clamping surface of the adapter ring runs parallel to the annular clamping surface of the cap on the inside of its upper wall.
• an advantageous embodiment of the feeding bottle according to the invention is further characterized in that the adapter ring is cup-shaped, with its outside conforming to the inside of the likewise cup-shaped cap, wherein preferably the outside of the cap is in turn conforming to the inside of a mounting section of a cup-shaped end cap, which is in the Snap fit is attached or attachable to the cap.

• the end cap can be used as a drinking cup.
• the bowl-shaped cap in the state in which it is placed on the bottle neck, secures in its axial position a retaining ring which sits on a shoulder transition between the bottle body and neck and carries projecting handles.
• the retaining ring contains a guide section which extends axially downward from the shoulder transition along the cylindrical bottle body and which is adjoined at the top by a support section which curves inwardly in cross section in accordance with the shoulder transition.
