Definitions

  • the present invention relates to containers comprising a suction outlet and an air inlet valve.
  • a negative pressure is created inside that container.
  • containers which can be used, for example, for liquids and semi-solids, are baby bottles and feeding bottles for sick and handicapped people which are intended to be used in an inverted or inclined orientation and sport-bicycle bottles.
  • Such bottles typically comprise a food or liquid containing portion (for the sake of brevity called food containing portion from now on) with a threaded or snap-fastener-equipped end opening by means of which a suitably shaped retaining ring for a suction outlet in the form of a teat or drinking straw can be releasably mounted.
  • containers which comprise automatic one-way air-inlet valves (from now on called valves for the sake of brevity) which open when the negative pressure exceeds a desired value and thereby allow air from outside the bottle to enter the bottle.
  • Such containers are known from, amongst others, WO-A-9007320, which has an adjustable valve formed in a pliable membrane in the base of a cylindrical container and DE-A- 29 44 279 which has a spring loaded valve mounted in the base of a cylindrical container.
  • WO-A-9007320 which has an adjustable valve formed in a pliable membrane in the base of a cylindrical container
  • DE-A- 29 44 279 which has a spring loaded valve mounted in the base of a cylindrical container.
  • valves in the base of the bottle has been considered desirable in order for the valve to be above the surface of the contents of the bottle when the bottle is the use position, i.e. when the bottle is inverted or inclined to the horizontal with the base upwards, in order to prevent the open valve and/or valve seat being contaminated with the contents of the bottle and subsequently failing to reseal properly.
  • valve described in WO-A-9007320 suffers also from the disadvantage that repeated heating during, for example, sterilising of the bottle leads to the pliable material losing some of its elasticity which affect its function.
  • the valve shown in GB-A- 2 108 854 is not adjustable and hence can not be adapted to the differing suction strengths of different users.
  • the invention seeks to provide a container of the above-mentioned kind in which the disadvantages of the prior art are avoided.
  • the present invention provides an accessory comprising an automatic one-way air-inlet valve which accessory is adaptable to be fitted on any feeding bottle between the food containing part of the bottle and the suction outlet retaining part of the bottle.
  • valve containing accessory is detachable from the food containing part of the bottle separate sterilising of the food containing part of the bottle and the valve is easily possible. If the valve containing accessory is heat sensitive it can be sterilised at a lower temperature or chemically or can be made of a cheap material and disposed of after one use. Alternatively the air inlet valve can be made easily detachable from the accessory for separate cleaning or sterilisation or disposal. Furthermore, contrary to expectations, during feeding the air sucked in when the valve is opened keeps the valve seat clean even if the valve is submerged in the contents of the bottle and thus there is no leakage during feeding.
  • Figure 1 shows a prior art feeding bottle without an air inlet valve.
  • Figure 2 shows a feeding bottle equipped with an air inlet valve according to one embodiment of the invention.
  • Figure 3 shows a partly cut-away schematic view of the bottle shown in figure 2.
  • Figures 4(A) and 4(B) show details of the air inlet valve adjusting device of figures 2 and 3.
  • Figure 5 shows schematically in section part of a feeding bottle equipped with an air inlet valve according to a second embodiment of the invention.
  • FIG. 1 shows a prior art feeding bottle 1 which has a food reservoir 2 with an open outlet end (not shown) provided with first fastening means in the form of external threads (not shown), and a suction outlet means 3 which in this example is a rubber teat 3 with a hole 4.
  • the teat 3 is retained on the reservoir 2 by a retaining means 5.
  • retaining means 5 comprises a clamping ring 5 with second fastening means in the form of internal threads (not shown) which co-operate with the first fastening means around the outlet end of the food reservoir 2 to retain the clamping ring 5 onto the food reservoir 2.
  • Other types of fastening means using snap fittings, bayonet fittings or the like are naturally also possible.
  • Figure 2 shows the feeding bottle of figure 1 equipped with an air inlet accessory means 6 according to a first embodiment of the present invention.
  • FIG 3 shows a part section through the bottle and accessory shown in figure 2.
  • the air inlet accessory means 6 has a substantially tubular vent body 7 which has an open end 8 provided with third fastening means in the form of internal threads 9 which can co-operate with the first fastening means in the form of external threads 10 around the outlet end 11 of the food reservoir 2 to retain the accessory means 6 onto the food reservoir 2.
  • the vent body 7 has a second open end 12 provided with fourth fastening means in the form of external threads 13 which can co-operate with the second fastening means in the form of internal threads 14 on the clamping ring 5 to hold the clamping ring 5 onto vent body 7.
  • air inlet valve means 15 is an adjustable spring-loaded ball valve 15 which has a valve body 16 which mounted in the vent body 7 by any suitable releasable or non-releasable means for example, co-operating threads, gluing, being moulded or cast into the vent body 7, welding, snap-fastening means, bayonet coupling means. If the valve body 16 is releasably attached to the vent body 7 it can be easily removed for cleaning and returned in its place. Alternatively the valve body or parts of the valve body can be disposed of after one use and replaced by a new valve body or valve body parts.
  • Naive body 16 comprises a cover 16a which is connected to or integral with a hollow, preferably cylindrical, upper valve part 16b.
  • Upper valve part 16b is releasably joined to a hollow, preferably cylindrical, valve base 16c by any suitable means for example a screwed joint, a bayonet joint, a snap-fitting, etc.
  • Cover 16 a contains at least one hole 16d connecting the hollow interior of valve body 16 with the outside.
  • the valve body 16 contains a concave valve seat 17, a valve element 18, a valve rod 19, a helical spring 20, a graduated spring protector disc 21 and an adjustment nut 22.
  • the valve seat 17 is provided at the inner end of the valve body 16 and has a hole 23 approximately in the centre through which the valve rod 19 passes.
  • the valve element 18 lies in the concave side of the valve seat 17 in contact with the fluid or the air inside the vent body 7 and forms a continuation of the valve rod 19 which is provided with threads 23.
  • the adjustment nut 22 is threaded onto the valve rod 19.
  • the helical spring 20 is situated on the rod 19 between the adjustment nut 22 and the valve seat 17. The compression of helical spring 20 can be increased by moving the adjustment nut 22 closer to the valve seat 17.
  • the nut 22 can be reached by disconnecting valve base 16c from upper valve part 16b. Increasing the compression of the spring 20 results in increased pressure of the valve element 18 against the valve seat 17. Consequently, more negative pressure has to build up before air can get into the bottle and vice versa.
  • valve body 16 is show in the figures as projecting perpendicular to the vent body 7 it can advantageously be inclined towards the bottom of the food reservoir 2 so that when the bottle 1 is resting on its base fluid and food runs away from valve seat 17.
  • Figure 4(A) shows an embodiment of a valve rod 19 is provided with a graduated scale 24. By altering the position of the nut 22 on the rod 19, the spring compression can be adjusted to a desired value as shown on the graduated scale 24.
  • Figure 4(B) shows a second embodiment of a graduating means in which the adjustment nut 22 is also provided with a graduated scale disk 25 which permits more accurate adjustment of the spring force.
  • the suction force is different for each baby and it can also change with age, hence it is useful to have a sensitive and adjustable air inlet valve so that it can be altered according to the need of the user. Leakage of fluid when the bottle and vent body 7 are lying down or held upside-down is prevented because the spring force of the valve prevents any spontaneous leakage of fluid from the bottle.
  • Figure 5 shows a second embodiment of the invention in which the helical spring 20 of the first embodiment is replaced by a leaf spring 26.
  • the spring force is adjustable by the nut 22 in the same manner as for the helical spring 20 above.
  • the invention is not limited to the spring type described above and any other type of suitable spring can conceivably be used, for example, one or more elastic rubber bands or sprung washers.
