EP0895773A1 - Feeding bottle with anti-air swallowing membrane - Google Patents

Abstract

The bottle comprises a receptacle (1) with a detachable base (2) and a microporous membrane (7) which has a anti-aeration properties and which extends into an opening (8) provided in the base. The membrane is integral with the base. The membrane may have several openings in the base. The membrane may be moulded over the base. The openings may be part of a support (6) fixed to the base and the membrane may be moulded over the support.

Description

The present invention relates to a bottle with anterophagic membrane.

We know such a bottle, described in document WO 89/11546, comprising a membrane angerophagic mounted on a peripheral support.

This support is then fixed on the opening of the bottom of the bottle by means of a ring screwed onto the body of the bottle, the anterophagic membrane being maintained between the end of the body of the bottle and the ring.

However, such a device comprises several parts that need to be perfectly adjusted when of the assembly, in order to avoid any leakage of liquid.

In addition, these different removable parts do not not facilitate cleaning and reassembly of the bottle.

The object of the present invention is to resolve the disadvantages mentioned above and to offer a bottle to anterophagic membrane for assembly and disassembly simplified.

The bottle targeted by the invention consists of by a container with a removable bottom and a microporous membrane with a function anaerophagic and extending into an opening formed in the removable bottom.

According to the invention, the microporous membrane is secured to the removable bottom.

Such an embodiment facilitates the cleaning the body of the bottle and the removable bottom.

In addition, the microporous membrane is mounted on the bottle directly when fixing the bottom removable on the body of the bottle, and does not require a high precision during assembly.

Preferably, the microporous membrane extends in several openings in the bottom removable.

This arrangement allows, for the same surface overall microporous membrane, to strengthen the removable bottom structure, the different portions of membrane of reduced dimensions being less subject to only one more microporous membrane large dimension.

Preferably, the microporous membrane is fixed by overmolding on the removable bottom.

Other features and advantages of the invention will appear further in the description below.

• la figure 1 est une vue en coupe longitudinale d'un biberon conforme à l'invention :
• la figure 2 est une vue en coupe, selon la ligne II-II à la figure 3 du fond amovible d'un biberon conforme à l'invention : et
• la figure 3 est une vue de dessus du fond amovible de la figure 2.

In the appended drawings, given by way of nonlimiting examples:

• FIG. 1 is a view in longitudinal section of a bottle according to the invention:
• FIG. 2 is a sectional view, along the line II-II in FIG. 3 of the removable bottom of a bottle according to the invention: and
• FIG. 3 is a top view of the removable bottom of FIG. 2.

Referring to Figure 1, a bottle is consisting of a substantially cylindrical repicient 1, by example in transparent plastic, such as polycarbonate.

This container has a removable bottom 2 and a microporous membrane 7 having a function anaerophagic and extending into an opening 8 formed in the removable base 2.

This membrane is impermeable to milk but breathable and thus allows the balance of pressures between the inside and outside of the bottle.

As shown in Figure 3, the membrane microporous 7 preferably extends in several openings 8 in the removable bottom 2 of the baby bottle.

The openings 8 are made in a support 6, here in the form of a disc which is fixed to the bottom removable 2.

The openings 8 are preferably distributed symmetrically around the center of the background.

The microporous membrane 7 is fixed by overmolding to the support 6, through each opening 8.

The support 6 itself can be fixed by overmolding in the removable base 2.

In this example, the support 6 is fixed to the center of the bottom part 5 of the removable bottom 2.

4 feet, for example 3, can equip the bottom part 5 with the removable bottom 2 for ensure good stability of the bottle.

In known manner, an elastomer seal can further be disposed between the removable bottom 2 and the body 1 of the bottle for sealing.

Of course, the invention is not limited to the example described above and many modifications could be made to it without depart from the scope of the invention.

Thus, the support 6 could be equipped with a only opening blocked by the microporous membrane.
