Definitions

  • the invention relates to a special adjustment of any closed container, residing in the fact that a flexible element is installed in the internal space of the container.
  • a spring or other material with a memory for shape can be used as the flexible element, e.g. plastic, rubber etc., which is capable of exerting pressure after compression or stretching.
  • the flexible element changes its shape from the original shape, i.e. from the resting position, it begins to impact upon the content of the container, which as a rule is gas or liquid, and thus creates overpressure within the internal space of the container. It is then possible to force out the content of the container into the external environment by means of the pressure of the flexible element, via a suitable valve.
  • the flexible element may be in direct contact with the internal content of the container, or may be separated from it via a suitable membrane or sealing.
  • the basis of the invention is a closed pressurised container furnished with at least one inbuilt flexible element.
  • a pressurised container the part of the container into which the flexible element is inserted, is referred to as a pressurised container.
  • the attachment of the flexible element to the pressurised container is resolved by the usual suitable methods of securing sufficient pressure and tightness, e.g. by a screw thread, lever stopper etc.
  • the body of the flexible element is capable of exerting pressure on the inner walls and the content of the pressurised container, or on the inner walls or volume of the flexible element itself.
  • pressurised bottle a combination of a pressurised container with a flexible element as described in this technical design.
  • the body of the flexible element copies the inner wall of the container and through its expansion reduces the internal space of the pressurised container.
  • the flexible element through its expansion progressively creates an essentially memory container with a reducing volume, which via the external walls compresses the volume of the pressurised container in the required direction.
  • the designation "memory" in this case means that the flexible element is made of a suitable material which remember its original shape, to which it attempts to return of its own accord, in the case that no external forces act upon it.
  • the flexible element which is essentially an elastic memory construction, then creates a separate closed container or is capable of separating the internal content (medium) of the pressurised container from itself, in which it is capable of expansion and contraction inside the pressurised container, as is evident from the attached images.
  • the part of the flexible element designated for attaching the flexible element to the pressurised container is formed by the head of the flexible element, furnished with a screw thread for anchoring the flexible element to the pressurised bottle.
  • the head of the flexible element further incorporates a release valve containing a lever and spring.
  • the spring represents any element capable of compression and returning to the original shape after the release of pressure generated by the shift of the release valve.
  • the head of the flexible element also incorporates an outlet hole and also a suitable neck.
  • the neck of the head of the flexible element enabling comfortable drinking of the liquid, is not an essential element for the functionality of this design, and may be replaced by other suitable equivalents, such as a drinking tube etc.
  • the head of the flexible element also contains an appropriate securing top of the flexible element in order to secure the body of the flexible element in its compressed shape if the body of the flexible element is expanded in its resting state.
  • the body of the flexible element is suitably furnished with a catch.
  • the body of the flexible element also contains a suitable base made of solid material, ensuring effective compression of the liquid from the space beneath the body of the flexible element in the direction towards the collecting tube. This design is presented e.g. in Fig. 3a to 3q .
  • the body and base of the flexible element enable discharge in the direction of the collecting tube, as is evident e.g. from Fig. 3f .
  • the liquid can be forced out directly into the outlet hole of the pressurised container.
  • the walls of the body of the flexible element are formed for example by springs inserted or cast into a plastic casing, rubber balloon, plastic piston etc.
  • This technical design incorporates various versions of the body of the flexible element, which in different physical versions fulfil the same function as described above. These versions are described in further detail in examples and illustrated in the attached images.
  • Fig. 1a to 1q The technical design illustrated in Fig. 1a to 1q is composed of a pressurised container furnished with an internal screw thread for attaching the flexible element.
  • the body of the flexible element in this case is formed by a spring, which is cast into a plastic casing.
  • the body and base of the flexible element contain discharge in the shape of the collecting tube, as is evident e.g. from Fig. 1h .
  • the walls of the flexible element copy the shape of the inner walls of the pressurised container.
  • the spring is extended in resting, i.e. here expanded shape, and after compression acts as a compressive spring.
  • the plastic casing of the flexible element is of a flexible membrane shape, in order to enable expansion and compression of the spring, but at the same time, together with the spring, to form a separate closed container.
  • the flexible element is in an expanded shape in the resting state, and upon its contraction pressure is generated, later released through its outer walls, or in other words the walls of the memory container, onto the internal space of the pressurised container. Securing of the flexible element in its compressed shape may be ensured e.g. by the above-mentioned catch.
  • the flexible element is created in inverse form, i.e. the flexible element is contracted, thus compressed, in resting state.
  • a securing top for example may serve as a catch for securing the flexible element in expanded state.
  • the flexible element must first of all be stretched, i.e. drawn into extended state, secured with a catch and filled with liquid. Stretching may be performed e.g. by a guide pin inbuilt into the external wall of the body of the flexible element and moving in a guide groove created within the wall of the pressurised container, as can be seen e.g. in Fig.
  • the design contains at least one pair of guid pegs and one pair of guide paths.
  • the internal walls of the flexible element in this case serve for retention of the liquid.
  • the hole in the neck of the head of the flexible element is furnished with a stopper instead of a securing top, which in this version is created in the base of the pressurised container, as can be seen from the attached images.
  • stretching of the flexible element is possible also by other suitable methods, for example wire/string attached to the base of the flexible element.
  • the flexible element is created in such a manner that the liquid is forced out by the flexible element from the base of the container, thus the flexible element is attached on the opposite end of the pressurised container to that where the release valve is located, which is opposite the above-described design of the components of the pressurised container and is not therefore created on the head of the flexible element.
  • This design also does not contain a collecting tube, since this is superfluous.
  • gas especially air may be pumped into the internal space of the memory container, i.e. the body of the flexible element, e.g. compressed air by an appropriately located pump or piston, and the expansive effect of the body of the flexible element may be increased by increasing the pressure within the internal space of the body of the flexible element.
  • This is therefore a combination of a mechanical principle and the principle of compressing liquid by overpressure.
  • the pulling or compressive force of the flexible element is dimensioned in the production of the entire pressurised bottle with regard to the requirements upon use, i.e. mainly a strong current, i.e. large through flow, is desirable for forcing out the liquid from the internal space of the bottle.
  • the materials from which the pressurised container or flexible element are to be produced are not unequivocally determined.
  • the choice of suitable materials depends mainly on the medium which the bottle is intended to store.
  • the internal medium chemical agents, contact with foodstuffs, contact with drinking water
  • the basic construction materials of the expansive body i.e. the flexible element:
  • the flexible element may be formed e.g. by a spring with a casing or sealing, a rubber casing, or casing with a memory function.
  • the base of the flexible element is furnished with sealing along the sides, which after insertion into the container seals around the perimeter to the wall of the container, as a result of which it is not necessary for the flexible element to contain a casing.
  • the technical design illustrated in Fig. 1a to 1q is composed of a pressurised container 1 furnished with an external screw thread 11 for affixing the flexible element 2 .
  • the flexible element 2 is made of a spring 21 , which is cast into a plastic casing, which creates the walls of the body 22 of the flexible element 2 .
  • the walls of the body 22 of the flexible element 2 copy the shape of the internal wall of the pressurised container 1 .
  • the spring 21 is extended in resting, i.e. expanded state, and after compression acts as a compressive spring.
  • the plastic casing forming the body 22 of the flexible element 2 is of a flexible membrane shape furnished with springs 21 in the place of the break of the membrane, in order to enable the spring to expand and contract, but at the same time together with the spring formed a separate closed container.
  • the lower part of the flexible element is ended with a solid base 26, onto which a catch 27 is affixed on the internal wall in an inward direction, serving in combination with the securing top 25 to secure the flexible element in its compressed state.
  • the upper part of the flexible element contains the following components:
  • a component of the pressurised container is a collecting tube 12 serving for inflow of liquid from the base 26 of the flexible element 2 to the outlet hole 231 in the neck 23 of the flexible element 2 .
  • Fig. 1h illustrates the channel 221 of the body 22 of the flexible element and the base 26 in the shape of a collecting tube 12, which flows into the collecting tube 12 .
  • a pressurised container according to this version of the design resides in the fact that first of all the pressurised container is filled with the required liquid.
  • the flexible element 2 or its flexible body 22, is compressed (from expanded into compressed state) and the pressure of the spring is secured with a securing top 25 , which secures the position of the catch 27 created in the lower part of the flexible element. Subsequently the flexible element is screwed onto the filled pressurised bottle and the pressure of the spring is released by rotation of the securing top 25 . In this manner the spring exerts constant pressure on the internal volume of the container. It is then possible to discharge the liquid from the container under pressure into the external environment via the release valve 24.
  • the technical design illustrated in Fig. 2a to 2p is composed of a pressurised container 1 furnished with an external screw thread 11 in the open top part.
  • the flexible element 2 is made from flexible material, in this case rubber, which together with the head 29 of the flexible element and the bottom base 26 at the same time forms a separate closed container.
  • the rubber membrane is contracted in resting state and after stretching forms a "pulling piston".
  • the rubber membrane is sufficiently flexible as to be capable of both expansion and contraction.
  • the rubber element 2 in the upper part contains the following components:
  • the flexible element 2 in the lower part is furnished with a catch 27, which after rotation of the securing top 25 deployed in the lower wall of the pressurised container 1 enables securing of the flexible element 2 in tightened state.
  • At least one guide path 31 created in the wall of the pressurised container 1 and at least one guide peg 32 moving in the guide path 31 serve for tightening of the flexible element 2 .
  • a pressurised container according to this version of the design resides in the fact that first of all the flexible element 2 is stretched following deployment of the guide peg 32 , or pair of guide pegs 32 and filled with the required liquid via the hole 251 .
  • the liquid and pressure generated by the rubber membrane which forms the side wall 22 of the flexible element 2 is secured in the internal area of the flexible element 2 by screwing the impregnating top 30 .
  • the thus filled flexible element 2 is inserted into the pressurised container 1 and screwed onto the screw thread 11 of the pressurised container 1 . It is then possible to discharge the liquid from the container under pressure into the external environment via the release valve 24.
  • Fig. 3a to 3q The technical design illustrated in Fig. 3a to 3q is essentially identical to alternative A as described in example 1, with the difference that the body 22 of the flexible element is made of flexible plastic material of a membrane shape with a memory function, which is expanded in resting state.
  • Fig. 4a to 4p is essentially a combination of alternative A and alternative B as described in examples 1 and 2, in which the body of the flexible element 2 is made of the same material as in example 1, but is contracted in resting state according to the model in example 2.
  • Fig. 5a to 5o The technical design illustrated in Fig. 5a to 5o is based on alternative A, but with the difference that the release valves, i.e. the neck 23 of the flexible element with outlet hole 231 and release valve 24 furnished with a lever 241 and spring 242 are made on the base of the pressurised container 1 instead of on the head 29 of the flexible element 2 .
  • the head 29 of the flexible element therefore contains only the screw thread 28 and hole 251 for inserting the securing top 25.
  • pressurised container resides in the fact that the pressurised bottle 1 is first of all filled with the required liquid.
  • the body 22 of the flexible element is compressed (from expanded to contracted state) and the pressure of the spring is secured with the securing top 25 , which secures the position of the catch 27 created in the lower part of the flexible element.
  • the flexible element is screwed onto the filled pressurised bottle and the pressure of the spring is released by turning the securing top 25 , as shown in Fig. 5n .
  • Fig. 6a to 6p The technical design illustrated in Fig. 6a to 6p is essentially identical to alternative E as described in example 5, with the difference that the body of the flexible element 2 is made from an open spring 21, which is expanded in resting state.
  • the base 26 of the flexible element upon contact with the wall of the pressurised container contains sealing elements 33 in order to ensure the impermeability of liquid to the construction of the spring 21.
  • Fig. 7a to 7m The technical design illustrated in Fig. 7a to 7m is essentially a combination of alternative B as described in example 2 and alternative E as described in example 5, with the proviso that the base 26 of the flexible element is fitted with a catch 27 in order to ensure the liquid-resistance outside the body 22 of the flexible element, in which the liquid is inlet through the hole 251 for the securing top 25 via the head 29 of the flexible element 2 .
  • the liquid may be forced out via the bridging 34 of the flow of liquid created in the head 29 of the flexible element for outflow of liquid into the collecting tube 12 of the pressurised container, as shown in Fig. 7m and 7l .
  • the invention is usable for personal use as a device for filling liquids, especially for sportspeople, also for drivers of motor vehicles, in which the bottle upon drinking does not obscure the user's view, but this design is usable everywhere it is necessary to create constant overpressure in the container without the use of further gases, liquids or complex mechanisms.
