Description

The invention relates to a special modification of any closed container in that a resilient element is installed in the interior of the container. As a resilient element, it is possible to use a spring or other shape memory material, such as plastic, rubber, etc., which can exert pressure upon compression or extension.

In the event that the elastic element changes its shape from the default, i.e. in the rest position, it thus affects the contents of the container, which is generally a gas or a liquid, creating an overpressure in the interior of the container. By pressure of the elastic element it is then possible to push the contents of the container into the external space via a suitable valve. The resilient element may be directly in contact with the inner contents of the container or may be separated therefrom via a suitable membrane or seal.

BACKGROUND OF THE INVENTION

At present there are several solutions for pressure vessels, which mainly work on the principle of compressed gas. Mechanically, it is also possible to use a movable piston inside the container based on the principles of hydraulics.

The disadvantage of such a solution is the necessity to fill the pressure vessel with compressed gas after each emptying or the need for a complicated hydraulic piston mechanism with corresponding sealing elements.

There is no such pressure vessel on the market that the user can simply fill himself up to create a permanent overpressure without using additional gases, liquids, or complex mechanisms. The solution according to the invention is particularly applicable in the field of conventional small beverage bottles or as part of dispensers, etc.

Especially in the field of sport, for example when running, classic bottles have the disadvantage that the liquid moves and splashes. In addition to the unpleasant sound effect, there is a constant change in the center of gravity of the entire bottle, and the athlete must level it by hand. Another disadvantage of today's standard sports bottles is that the user usually has to suck the fluid, which disrupts his breathing rhythm. It is also advantageous that the water from the bottle is sprayed under pressure, so that it is not necessary to tilt the head when drinking. It is also possible at each moment and at any position of the bottle to accurately determine the residual amount of fluid in the container.

SUMMARY OF THE INVENTION

The present invention is based on a closed pressure vessel provided with at least one built-in resilient element. Hereinafter, the pressure vessel is the portion of the vessel into which the resilient element is inserted. The fastening of the elastic element to the pressure vessel is solved by conventional suitable methods of ensuring sufficient pressure and tightness, for example by screw thread, lever lock, etc. In order to ensure the functionality of the pressure vessel according to this solution, it is not decisive whether the thread is formed on the outer or inner side of the pressure vessel, but with respect to the thread clogging it is obviously advantageous that the thread is formed on the outer wall of the pressure vessel.

The body of the elastic element can exert pressure on the inner walls and the contents of the pressure vessel, or on the inner walls respectively. the volume of the elastic element itself.

When referring herein to a " cylinder, " it is the resultant product, i.e., a combination of a pressure vessel with a resilient element described herein.

The body of the resilient element follows the inner walls of the vessel and expands to reduce the inner space of the pressure vessel. The elastic element gradually expands to form a substantially variable volume storage vessel that compresses the contents of the pressure vessel in the desired direction through the outer walls. The term "memory" in this case means that the resilient element is made of a suitable material that remembers its initial shape to which it attempts to return spontaneously when no external forces are applied to it. The resilient element, which is a substantially elastic memory structure, then forms a separate closed vessel or can separate the inner volume (medium) of the pressure vessel from itself, being capable of expansion and contraction within the pressure vessel, as shown in the accompanying drawings.

In a variant embodiment of the present invention, the portion of the resilient element for attaching the resilient element to the pressure vessel is formed by a threaded head of the resilient element for attaching the resilient element to the cylinder. The spring element head further comprises a discharge valve comprising a lever and a spring. The spring represents any element capable of compressing and restoring to the original shape upon release of the pressure induced by the displacement valve displacement. The head of the resilient element further comprises a resilient dispensing element replaced by a necessary element replaced by other aperture and preferably also by a throat. The throat allowing comfortable to function this with suitable equivalents, drinking, etc. The head of the elastic element of the drinking fluid solution and the head may not be like the tubing preferably includes also on the locking cap of the elastic element to secure the body of the elastic element in a compressed shape when the body of the elastic element is expanded. For this purpose, the body of the elastic element is preferably provided with a lock. The body of the elastic element also preferably comprises a bottom formed of a rigid material ensuring efficient liquid displacement from the space below the body of the elastic element towards the collecting tube.

This solution is illustrated, for example, in FIG.

In the embodiment, the liquid may be displaced

3a to 3q. Next directly to the pressure vessel outlet.

The walls of the body of the elastic element comprise, for example, springs inserted or embedded in a plastic housing, a rubber balloon, a plastic piston, and the like. The present invention encompasses various embodiments of the body of the resilient element which, in different physical designs, perform the same function described above. These embodiments are described in more detail in the examples and illustrated in the accompanying drawings.

The technical solution shown in FIG. 1a-1q consists of a pressure vessel provided with an external thread for fastening the elastic element. The body of the elastic element is in this case formed of a spring which is embedded in a plastic housing.

The walls of the elastic element follow the shape of the inner wall of the pressure vessel. The spring is expanded in the rest, i.e. expanded, state and acts as a compression spring upon compression. The plastic housing of the resilient element is resilient in membrane shape to allow expansion and compression of the spring, but at the same time forms a separate closed container together with the spring.

If the body of the elastic element is contracted in the rest state, then we are also talking about its contraction, resp. contracted state. Otherwise, i.e., if it is expanded in the idle state, i.e., the " expanded, then when putting into a compressed or contracted state we are also talking about its compression, ie. compression.

In one embodiment of the memory container, the resilient element is in an expanded shape at rest, with its contraction exerting a pressure later released by its outer walls, respectively. in other words, through the walls of the memory vessel, to the interior of the pressure vessel. For example, the aforementioned fuse may serve to secure the elastic element in a compressed form.

In another embodiment of the memory container, the resilient element is formed in an inverse form, i.e. the resilient element is contracted or contracted in the rest state. 2a to 2p or 4a to 4p. For example, a locking cap can be used as a safety device to secure the elastic element in the expanded state. In this case, the elastic element must first be stretched, i.e. brought to the state of extension, secured with a fuse and filled with fluid. For example, a guide pin inserted into the outer wall of the body of the resilient element and moving in a guide groove formed in the wall of the pressure vessel can be used for stretching, as shown, for example, in Figures 2e, 2f, 2k, 21, 4e, 4f, 4k and 41. In a preferred embodiment, at least one pair of guide pins and one pair of guide grooves are provided for uniformly distributing the force required to stretch the body of the elastic element. In this case, the inner walls of the elastic element serve for fluid retention. In this embodiment, the opening in the throat of the head of the elastic element is provided with a closure instead of a locking cap, which in this embodiment is formed in the bottom of the pressure vessel, as further shown in the accompanying figures. However, the elastic element can be stretched in other suitable ways, for example by means of a cord / rope attached to the bottom of the elastic element.

In a variant embodiment of the memory container of Figs. 5a to 50o and 6a to 6p, the resilient element is formed such that the fluid is forced out by the resilient element from the bottom of the receptacle, respectively. the attachment of the resilient element is provided at the opposite end of the pressure vessel than the dispensing valve, which is part of the pressure vessel and is not formed on the head of the resilient element, as opposed to the solutions described above. This solution also does not include a collecting tube as it is superfluous.

The solutions described above can be applied to any sealed container such as drinking bottles, containers for various cleaners and chemicals, sprayers, cosmetics, etc.

In a preferred embodiment, gas, in particular air, may be injected into the interior of the memory container, i.e. the body of the resilient element, and by increasing the pressure in the interior of the body of the resilient element, the expansion effect of the body of the resilient element may be increased. . It is therefore a combination of the mechanical principle and the principle of liquid ejection by positive pressure. The tensile or compressive force of the body of the elastic element is dimensioned in the manufacture of the entire cylinder according to the requirements in use, i. mainly as a high current, i.e. a high flow, is desirable to expel fluid from the interior of the bottle.

It is not unambiguously given which materials the pressure vessel or the elastic element is made. The choice of suitable materials depends mainly on the medium to be stored in the bottle.

The elastic element 2 is formed by a spring 21 which is embedded in a plastic casing which forms the walls of the body 22 of the elastic element 2. the shape of the inner wall of the pressure vessel 1. The spring 21 is at rest, ie. in the expanded, expanded state and after compression it acts as a compression spring. The plastic housing constituting the body 22 of the resilient element 22 is a resilient membrane-shaped spring having springs 21 at the point of rupture of the membrane to allow the spring to expand and contract, but at the same time form a separate closed container together with the spring. The lower part of the elastic element is terminated by a fixed bottom 26, to whose inner wall towards the inside of the elastic element there is a fuse 27 serving in connection with the locking cap 25 to secure the elastic element in a compressed state.

The elastic element 2 at the top includes:

a female threaded head 29 for attaching the resilient element 2 to the cylinder 1;

a discharge valve 24 provided with a lever 241 and a spring 242; a securing cap 25 of the resilient element housed in the opening 251;

a neck 23 of a flexible element with a discharge opening 231;

The pressure vessel includes a collecting tube 12 for supplying fluid from the bottom 26 of the resilient element 2 to the discharge opening 231 in the neck 23 of the resilient element X

The use of the pressure vessel according to this variant solution consists in that first the pressure vessel is filled with the required liquid. The spring element 2, respectively. its spring body 22 is squeezed (converted from the expanded state to the compressed state) and the spring pressure is secured by a locking cap 25 that secures the position of the fuse 27 formed in the lower portion of the elastic element. Subsequently, the spring element is screwed onto the filled cylinder and the spring pressure is released by turning the locking cap 25. This creates a constant pressure on the inner volume of the vessel. The fluid 24 can then be discharged from the vessel under pressure into the external space via the drain valve 24.

Example 2

Variant B

The technical solution shown in FIG. 2a to 2p consists of a pressure vessel 1 with an external thread 11 in the upper open portion. The resilient element 2 is formed of a resilient material, in this case a rubber, which together with the resilient element head 29 and the bottom bottom 26 simultaneously form a separate closed container. The rubber diaphragm shrinks in the rest state and, after stretching, forms a so-called pulling piston. The rubber membrane is flexible enough to be able to expand and contract.

The elastic element 2 at the top includes:

a female threaded head 29 for attaching the resilient element 2 to the cylinder 1;

a closure 30 with an opening 251 for inflating the resilient element 2;

a discharge valve 24 provided with a lever 241 and a spring 242;

a neck 23 of a flexible element with a discharge opening 231;

The resilient element 2 is provided in the lower part with a fuse 27 which, after rotation of the locking cap 25 connected to the bottom wall of the pressure vessel 1, enables the resilient element 2 to be locked in the extended state.

• · · ·

At least one guide groove 31 formed in the wall of the pressure vessel 1 and at least one guide pin 32 extending in the guide groove 31 serve to stretch the elastic element 2.

The use of a cylinder according to this variant solution consists in that first the elastic element 2 is stretched after engagement of the guide pin 32, preferably a pair of guide pins 32, and filled through the opening 251 with the desired fluid. The fluid and pressure exerted by the rubber diaphragm that forms the side wall 22 of the elastic element 2 is secured in the interior of the elastic element 2 by screwing the inlet cap 30. The spring element 2 thus filled is inserted into the pressure vessel 1 and screwed onto the thread 11 of the pressure vessel 1. Via the discharge valve 24, it is then possible to discharge the fluid under pressure into the external space.

Example 3

Variant C

The technical solution shown in FIG. Figures 3a to 3q are substantially the same as variant A described in Example 1, except that the body 22 of the elastic element is made of a flexible plastic material of membrane-shaped shape with a memory function that is expanded at rest.

Example 4

Variant D

The technical solution shown in FIG. 4a to 4p is essentially a combination of variant A and variant B as described in Examples 1 and 2, wherein the body of the elastic element 2 is formed of the same material as in Example 1, but, following the example of Example 2, is shrunk.

Example 5

Option E

The technical solution shown in FIG. 5a to 5o are based on variant A, but the difference from variant A is that the discharge elements, i.e. the neck 23 of the flexible element with the discharge opening 231 and the discharge valve 24 provided with the lever 241 and spring 242 are formed at the bottom of the pressure vessel 1; instead, they are formed on the head 29 of the elastic element 2. Thus, the head 29 of the elastic element comprises only a thread 28 and an opening 251 for receiving the locking cap 25.

The use of a pressure vessel according to this variant solution consists, as in Example 1, of first filling the cylinder 1 with the desired liquid. The spring element body 22 is squeezed (converted from the expanded state to the compressed state) and the spring pressure is secured by a locking cap 25 that secures the position of the fuse 27 formed at the bottom of the spring element. Subsequently, the spring element is screwed onto the filled cylinder and the spring pressure is released by turning the locking cap 25, as shown in FIG. 5n.

Example 6

Variant F

The technical solution shown in FIG. 6a to 6p are substantially identical to variant E described in Example 5, except that the body of the elastic element 2 is formed from an open spring 21, which is expanded in the rest state. The bottom 26 of the spring element comprises sealing elements 33 in contact with the wall of the pressure vessel to ensure that the fluid is impermeable to the spring structure 21.

Example 7

Variant G

The technical solution shown in FIG. 7a to 7m is essentially a combination of Variant B described in Example 2 and Variant E described in Example 5, with the bottom 26 of the spring element having a lock 27 to provide fluid impermeability outside the spring element body 22, wherein the fluid is impregnated with the opening 251 for the spring. The locking cap 25 over the head 29 of the resilient element 2. Fluid may be expelled through the fluid flow bridging 34 formed in the head 29 of the resilient element to drain the fluid into the collecting tube 12 of the pressure vessel, as shown in FIGS. 7m and 71.

The technical solution according to the invention can be used for personal use as a means of replenishing fluids, especially for athletes, also for motor vehicle drivers, when the bottle does not obstruct its vision while drinking, but this solution can be used wherever there is a need without using other gases, liquids or complex mechanisms.
