Definitions
- the invention relates to a drinking bottle with a container open at both ends for flexible disposable insert bags for holding food liquid and with a closure cap which can be screwed onto the container and which carries a teat.
- Drinking bottles of the type used for infants are known. Such systems have the advantage over conventional drinking bottles that there is no vacuum in the bottle when drinking, since the flexible insert bag closes flat with increasing emptying. No air can penetrate into the flexible insert bag through the opening of the suction device, as is the case with the usual rigid liquid container due to the gravity of the liquid in the vertical standing or transverse position. The baby needs less energy when swallowing to overcome the vacuum, and the risk of swallowing or air swallowing that causes discomfort is excluded in principle.
- the systems are more practical and handy, since there is no need to clean the water bottle every time due to the disposable insert bags, so that no unsanitary food or washing-up residues can remain in the bottle.
- the food liquid in this plastic bag can also be warmed up faster and with less energy than in the conventional drinking bottle.
- the object of the invention is therefore to create a drinking bottle of the type mentioned, which overcomes the disadvantages mentioned.
- the container has a longitudinal slot open on the side of the closure cap and in that a retaining ring for holding the insert bags on the edge of the container can be plugged on.
- the insert bag can now be easily inserted into the longitudinal slot from the side. In this way, the edge of the insert bag is held all around by the retaining ring. This handling is quick, handy and hygienic and does not have to be carried out as carefully as with other known drinking flakes.
- the retaining ring preferably has a sleeve-shaped part, at one end of which a flange-shaped part is arranged. As a result, it covers the front side and the outer circumference of the container rim when plugged in and is clamped by the closing cap.
- the flange-shaped part can also be dispensed with, in which case the suction cup covers the end face of the container edge.
- inwardly projecting cams or a continuous bead can be arranged in order to improve the retention of the insert bag and to hold the retaining ring on the edge of the container in the manner of a snap closure.
- the retaining ring is made of a semi-hard material, it is both easier to put on the edge of the container and the sealing effect between the insert bag and the closing cap is improved. A further improvement of the sealing effect is achieved if a with the in the area between the sleeve-shaped part and the flange-shaped part Container edge cooperating, inwardly projecting sealing element is arranged.
- the longitudinal slot, the container edge and the retaining ring are preferably dimensioned such that the longitudinal slot in the region of the container edge is at least approximately closed when the retaining ring is attached. This prevents damage and leaks in the insert bag in the area of the longitudinal slot.
- the container should be so elastic that it can be slightly compressed at the top, so that the retaining ring can easily be slipped over the folded edge of the bag and pressed and held over the edge of the container. This requires a certain elasticity of the container, which can be increased in that the longitudinal slot has an extension at the end facing away from the closing cap. Such an extension also reduces the risk of stress cracks in the container.
- Another measure to reduce the risk of cracks is that the edges of the longitudinal slot have thickenings over at least part of its length. This also prevents anyone from injuring themselves on sharp edges of the longitudinal slot.
- the drinking bottle described is not only suitable for small children, but also for the sick and disabled.
- FIG. 2 shows an enlarged detail from FIG. 1,
- Figure 4 is an enlarged detail of Figure 3 and 5 shows a section corresponding to FIG. 4 with a different embodiment of the retaining ring.
- the tubular container 1 shown in FIG. 1, open at both ends, is made of plastic and is preferably transparent. In the area of its upper end it is provided with an external thread 2 with a large pitch for screwing on the closing cap 21.
- the insert bag 11 is made of thin and flexible plastic and is known per se. It is inserted into the container 1 from the side in the direction of the arrows 14 through the longitudinal slot 3 in the flat folded and elongated state. In order to facilitate the insertion of the insert bag into the longitudinal slot, the bag can be rounded at its closed end, as is indicated by the reference number 12 in FIG. 1. After insertion into the container, the open end of the insert bag 11 is turned inside out and placed over the container edge 7.
- the insert bag 11 has two tabs 13 at its open end, on which it can be held and pulled over the container edge 7.
- the container is then slightly compressed at the top, which is facilitated by the elastic slot 3, and the retaining ring 15 is pushed onto the edge from above and pressed down until it engages under the container edge with cams or a bead 18 projecting inwards at its edge and snaps in, as can be seen particularly clearly in FIG. 4.
- the end 4 (FIG. 2) of the longitudinal slot 3 in the region of the container edge 7 is closed, so that the insert bag lies on the entire circumference of the container edge.
- the longitudinal slot 3 can be provided with an extension 5 at the lower end.
- the edges of the longitudinal slot 3 preferably have thickenings 6. This also facilitates the insertion of the insert bags.
- the retaining ring 15 consists of a sleeve-shaped part 16 and a flange-shaped part 17. It is made of semi-hard material, which means that it is softer than the container 1, but not as soft as usual Sucker 27 are. This property makes it easier to place the retaining ring 15 on the container edge 7 and holding and in particular sealing the insert bag 11 in the container opening.
- the retaining ring 15 has a one-piece molded sealing element 20, which in the present example has the shape of a circumferential rib.
- the sealing element 20 could also be designed as an integrally formed sealing lip, as an elastic sealing ring inserted into a correspondingly shaped groove or as a cast-on or otherwise applied sealing area made of a material that differs from the material of the retaining ring.
- This sealing element 20 interacts with the rounded container edge 7 in such a way that the insert bag 11 located in between is centered on the container edge and held in such a way that it cannot slide down when the bag is filled with the nutrient liquid.
- the closing cap 21 which receives a flange 28 of the suction cup 27 in an annular groove 22, is screwed onto the container 1 by means of its internal thread 23. The screwing movement is facilitated by ribs 24 on the closure cap and ribs 9 on the container 1. By screwing the closing cap 21 on, an additional compressive force is exerted on the retaining ring 15.
- the sealing element 20 is arranged in the region 19 of the retaining ring such that it rests on the insert bag 11 between the end region and the outer circumference of the bead 8 of the container edge 7.
- the aforementioned compressive force is divided into an axial and a radial component, the axial component causing the sealing element 20 to slide down on the bead 8 and thereby smoothing out any wrinkles still present in the insert bag 11.
- the container 7 is compressed by the radial force component in such a way that the longitudinal slot 3 closes completely in the region of the container edge, if this has not already been achieved by inserting the retaining ring 15.
- FIG. 5 An alternative embodiment of the retaining ring 15 is shown in FIG.
- the retaining ring according to FIG. 5 does not have a flange-shaped part that overlaps the end face of the container edge 7, but rather an inclined surface formed in the region 19, which lies against the bead 8 of the container edge 7 with the insert bag 11 being interposed .
- the sealing element 20 can be omitted because at In this embodiment, the suction cup 27 assumes the sealing function by being pressed axially downward through the closing cap 21 and pressing the insert bag 11 against the end face of the container rim 7.
- This retaining ring also generates a radial force component when the closing cap is screwed on, by means of which the longitudinal slot 3 in the region of the container edge 7 is completely closed, as was described above in connection with FIG. 4. 5, the height distance between the lower edge of the closure cap 21 and the outer ribs 9 of the container 1 must be greater than the thickness of the inwardly projecting flange-shaped part 17 of the retaining ring 15 according to FIG. 4, so that the closure cap 21 is at least as far can be screwed that the lower edge of the suction cup 27 touches the container edge 7.
- a protective cap 25 is placed on the closing cap 21, the teat 27 being able to be slipped downwards in a known manner.
- the protective cap can also be made so long that it covers the suction device that is not inserted.
- the protective cap 25 has a stepped shoulder 26 which fits into the lower edge 10 of the container 1, so that several of them can be stacked on top of one another for the storage or intermediate storage of empty or filled containers.
- the plastic insert bags are preferably sterilized and can be unrolled and separated as disposable bags from a supply roll. They should be strong enough that food liquid can also be stored and frozen in it.
