Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a valve device for inflating a balloon supported by a shaft.

Latex balloons are widely known and commercially available. Since such balloons are made of latex, their surfaces are extremely susceptible to deformation. The balloon can be of any desired shape and has a reduced diameter end, commonly referred to as a neck. A tubular support shaft is inserted into this neck.

Once the balloon is inflated, a knot in the neck prevents the air or gas from escaping. The end of this neck is closed in a notch formed laterally around the tapered joint. The base of the fitting is located within a tubular support shaft as a pressure source.

This sealing process is inconvenient, time consuming, and does not provide complete sealing. In fact, once the balloon is inflated, it will only remain stable if it is placed vertically on the shaft.

Additionally, if the balloon is made of a material with limited deformability, especially a thin layered material such as polyester, which has high tensile strength but limited deformability, it is difficult to pull the neck to tie a knot. becomes.

Other types of closure means, such as clamping or tying the neck, generally cannot guarantee a complete seal.

Additionally, balloons cannot be rolled up or folded.

Must be.

A balloon with limited deformability applies in particular if at least one of its surfaces is a metallized mirror surface. In this case, the Noh masks depict scenes from fairy tales or stories, or display advertisements for products, clubs, etc. In such a case,
Improvements are required to reduce image distortion, yet allow for re-inflating, avoid unpredictable folding or bending, and be easy to handle so that it can be displayed in all directions.

The object of the invention is to provide a device for inflating a balloon which does not have the above-mentioned drawbacks and which ensures a secure attachment of the balloon to the support shaft.

According to the invention, the above object can be achieved by a one-way valve device, operating at low pressure, which is inserted into the support shaft or at one end thereof and which together with the body performs the sealing of the neck of the balloon.

The main features of this one-way valve device are as follows.

tal The outer shape is sufficient to allow the neck of the balloon to deform, maintain the inflation pressure and maintain the new pressure, and at the same time, when the neck of the inflated balloon exceeds its shape and the balloon is deflated, it will return to its original shape. so that you can return to

(bl) The internal shape is such that it can be inserted into either end of the external handling shaft and the internal support shaft, and its central portion is shaped to allow the installation of a one-way sealing system for the inflation fluid. The directional sealing system consists of a small cylindrical chamber closed by two bases, each of which has a small hole cut through its center. , the one closer to the balloon has protruding radially intersecting ribs.

A valve seat piece slides between these two bases at a distance less than the diameter of the bases. This patent piece consists of a disk of highly elastic material, the diameter of which is slightly smaller than the diameter of the base, which can move up and down inside a cylindrical chamber guided by the wall; You will never get stuck or get stuck in the middle.

When air is blown in from the direction of the smooth base by any means, the resilient valve piece lifts up and is pressed against the ribbed base above it, causing the air to flow between the walls and the resilient valve piece. Flow towards the ribs through the edges between.

When the external pressure ceases and the valve piece is no longer supported, it falls downward to the smooth base, is forced by counterpressure, and achieves a complete seal by adhering to the smooth base surface.

The disk of elastic material which acts as a seal in this valve arrangement is not satisfactory for balloons which remain inflated for long periods of time. To overcome this drawback, the sealing disc can be replaced by a small hollow cylinder if appropriate. The cylinder slides within a cylindrical chamber and has a tapered plug that fits into a central hole in a smooth base and a protruding circular rim that grips the surface of the smooth base.

It is also possible to provide the above-mentioned hollow cylindrical body (4:) with a protruding circular rib. This circular rib fits between the two circular ribs on the smooth base. The thin and highly flexible pieces provided ensure a perfect seal.

As mentioned above, the configuration of the valve device of the present invention is such that the neck of the balloon is expanded to ensure a tight seal. However, in the case of large balloons and/or helium-filled gases, the seal between the balloon neck and the valve arrangement must be external to the balloon neck and easily removable. This can be improved by using a sealing sleeve.

A cylindrical chamber in which a movable member slides to open or close a communication hole between the inflating balloon and the outside world.
Can be obtained within the balloon support shaft. To this end, the shaft is divided into two parts, the two ends of which are thermoformed, vacuum or blow-formed to form the two halves of the chamber.

These halves can be force fit. When these two shaped ends are joined, a chamber is formed inside. A sealing piece slides within this chamber. On the other hand, the exterior is formed with a bulging surface which fits into the neck of the balloon and provides the necessary tension to ensure a tight seal.

In the case of a balloon with limited elastic deformation supported by a hollow shaft, the one-way valve arrangement according to the invention can be arranged at the free end of this shaft. In such constructions, it is preferable to use a hand-sealing one-way valve arrangement. In such devices, the valve is closed once the balloon has been inflated by manually inserting a conical plug into the inflating gas hole or appropriate air hole in the valve device.

Hollow shafts can be obtained by pultrusion.

If it is smooth, there will be high friction at the neck of the balloon, especially in the case of balloons with limited elasticity, or an insufficient external seal. This significant improvement in external sealing can be obtained in accordance with the present invention without eliminating the use of low cost pultruded shafts. That is, according to the present invention, an ordinary round-shaped drawn tube of a constant diameter is used, and the part to be inserted into the neck is preheated using a known blow molding technique, and the tube is placed in a mold and bulged to form a bulged portion. be.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to preferred embodiments illustrated in the accompanying drawings.

With particular reference to FIGS. 1-4, a one-way valve device 1 for purposes of the present invention is inserted into the neck 3 of a balloon 2. FIG. Two tubular shafts 10.12 are connected to this valve arrangement 1,
one of which extends to the outside and the other to the inside of the balloon 2.

As shown in detail in FIGS. 2, 3 and 4, the valve arrangement 1 comprises a lower element 1 to which a shaft lO is crimped.
1 and an upper element 1 to which the shaft 12 is crimped.
It consists of 4.

The lower element 11 has a small diameter end 16 with a snap ring 21'Ia1' and a stop 17. The upper element 14 is pressed into its end 16 until it abuts the stop 17. two elements)
11,140 the outer surface has several slightly raised annular ribs 20 that press elastically against the inner wall 15 of the neck 3. The lower element 11 also has a slightly elongated extension 18 in it, which includes a wall 15 of the neck 3.
is closely attached.

Said annular rib 20 and extension 18 ensure a 7-hole on the outside of the valve arrangement 1, and on the inside of the valve arrangement 1 there is a valve sealing element.

The two elements 11, 14 connected together have a small cylindrical chamber 4. This chamber 4 has the same diameter as the end 16 of the lower element 11 and has two bases 5.6.
surrounded by The lower base 5 is completely flat and has a central hole 19, and the upper base 6 has a series of radial ribs 23 and a central hole 24. This center hole is 4
A taper is attached to the 5° slope.

Between the bases 5.6 there is a very light and elastic disk 22 of elastomer, provided with radial fins.
Easier to slide along walls. The diameter of this disc 22 is smaller than the diameter of the end 16 of the lower element 11 and larger than the sum of the diameter of the central hole 19 and the radius of the end 16, so that in every position the disc 22 always When facing each other, the central hole 19 is completely covered.

A modification of the valve chamber 4 is shown in FIG. Here, the lower base 5
has a completely flat conical valve seat 25 in the area of the central hole 19, on which is a hard or elastic smooth sphere 32 of metal or plastic material with a diameter 6 much larger than the central hole 24. Be seated.

Regardless of the variant, the operation of the valve device is the same. Air entering from the tubular shaft 10 passes through the central hole 19, lifts the /-le disc 22 or sphere 32, moves them towards the radial lip 23, passes through the central hole 24,
It enters the inside of the balloon 2 through a shaft 12 which prevents bending of the neck 3 and any constriction in the deflated state of the balloon.

The air entering balloon 2 inflates it and creates excess pressure. As soon as the inflation by mouth or suitable pond means is completed, the internal excess pressure will cause the disc 22 or the sphere 3 to
2 back into their smooth valve seats to create a complete seal.

Internal excess pressure is removed by the outer annular rib 20 and extension 18.
The 7-bar cannot be loosened, so the balloon remains inflated and can be further inflated.

The inner shaft 12 prevents the balloon from lenticularly waving or bending to one side, so that the balloon can be oriented in the desired direction and positioned in the middle of the balloon in a plane passing through it. It maintains a flat surface.

- To deflate the balloon, it is sufficient to bend the upper element 14 from the outside of the neck 3 of the balloon;
Push the overlapping part of the above onto the lower element 11,
7) It is better to pull out the valve device 1 together with 10 and 12.

Another variation of the valve arrangement described above, or an improved sealing of the valve arrangement, can be obtained by passing the top of the shaft 120 through a molded elastomeric laminated, resilient dual tongue 26.

Even without internal pressure, it is partially cylindrical, but its tip 27 is bent and its bend 28
is in a closed state. As air is admitted into the balloon 2 through the shaft 12, the normally flat tip 27 is enlarged in length and diameter and takes up the vertical position 2 shown in dashed lines in the drawing.
9-30, allowing air to enter the balloon.

When the air flow and outside pressure are removed, the tip 27 collapses back to its bent shape and is compressed by the internal excess pressure to create the appropriate valve.

Figures 7-12 illustrate a particular type of one-way valve arrangement that allows for very long inflation times.

According to this embodiment, a hollow 7-ring or piston 31 with a diameter slightly smaller than the end 16 of the shirt 10 and a length shorter than the distance between the two bases 5. It slides in a cylindrical chamber 4 surrounded by 6.

The outer surface of the lower base 5 of the cylinder 31 is provided with a conical plug 35 having the same taper as the central bore 19 and a slightly raised rim 36 .

The walls of the cylinder 31 can slide with some clearance in the cylindrical chamber 4 and assume the end position shown in FIGS. 8 and 9.

In the position of FIG. 8, air flows according to @A-AI. In the position of FIG. 9, where the force A is removed, the plug 35 enters the central hole 19 under the pressure of the air trying to escape. At the same time, the rim 36 is crimped onto the base 5.

The action of the internal pressure to close the valve is not necessarily assisted or preceded by any kind of calibrated spring 37 inserted into the cylinder 31 and acting against the upper base 6.

The cylinder 31 is made of an elastic material and its walls can be deformed to fit completely against the surface of the base 50. 10th
Figures 1 through 12 show another variant with a double/rule.

In this variant, the cylinder 31 is provided with a circularly raised rib 33 of diameter D3 above the lower base 5, and on the upstream side the base 5 is concentric with the central hole 19 and has diameters D1, D2 and is equal. It is integrally constructed by having two raised circular lips 34. Since the diameter D3 is given the difference between Dl and D2, the circular rib 33 is located in the closed position between the lips 34.

Between the base 5 and the 7 cylinder 31 there is a highly flexible sheet seal 38. It is preferably made of elastomer or rubber.

FIG. 11 shows the situation when air is injected.

The airflow to the balloon now follows the path A-AI. On the other hand, when the inflation is stopped, the counter pressure of the air built up inside the balloon 2 creates the situation shown in Figure 12, where /-
As the tube 38 is compressed and bent, three sealing points are obtained between the tubes 33 and 34, which are secured to each other.

Also, in this embodiment, any type of calibrated spring 37 can be suitably housed inside the piston 31 to assist or preempt the action of internal air pressure. In either case, the flex seal of the flexible part creates a sole point that eliminates porosity in the molded part, extending the inflation time by many days.

Apart from diffusion through the materials of the various parts, the further stretching which makes the 7-ru practically permanent is between the 7-ru 38 and the base 5 in FIG. This is obtained by inserting an impermeable oil film between the plug 35 and the base 5.

Oxygen, elastomers and thermoplastics used (as opposed to inert oils forming a permanent and absolute barrier without porosity in the compression area; in this case, low molecular weight silicone) Oils or low molecular weight polyisobutylene are particularly suitable, the former being very chemically stable and highly non-hygroscopic, the latter also having sufficient adsorptive properties.

For large balloons, especially when inflated with helium, the two membranes 1 of the valve arrangement, together with the outer 7-le sleeve, are used as shown in FIGS. 13-17.
It is advisable to ensure a seal between -11 and 14. For this purpose, 1. The seal between the elements 11, 14 is ensured by passing through the ring 21 and forming the lower element 11 into a sleeve. Especially the first
3 to 15, the lower element 11
has a diameter increasing from the area of the stop 17 and is surrounded by a hollow, externally tapered protective rib 39. The end 40 of the lower element 11 is
It is sufficiently flexible and thin so that it is slightly deformed by the insertion force of the paddle 10.

Between the protective rib 39 and the end 40 there is a tapered space, preferably reinforced by four ribs 41. rib 3
9 easily slides within the wall 15 and creates a strong force at its upper end, which ensures a good seal even with self-supporting or floating helium as the required gas for the balloon.

To prevent the balloon from escaping and towering over the top of the support shaft 10.

A cord or string can be attached to the balloon 2.

In order to attach such a cord at a low cost, a knot 42' is provided at one end of the cord 42, and two retaining plates 43 and 42', which are integrally connected to the slotted shaft 40 by molding, are attached. 43'.

Further, as shown in FIG. 16, a rib 39' can be formed by molding or the like on the extension of the upper element 14 of the valve device. In this embodiment, rib 3
9' is provided with a seat for inserting the lower element 11 inside thereof.

A further improved seal is obtained by inserting a simple seal 44, as shown in FIG. This 7
The sample seal consists of two ring dead-end seals, the outer ring of which is fixed to the inner podium of the cylinder 40, and the inner dead-end ring tightly compressed between the inner wall of the cylinder 40 and the hollow shaft 10 for helium. has formed an absolute seal.

The cylindrical chamber 4 of the valve device 10 also has shafts 10 and 12
can be attached directly to the support shaft by thermoforming the ends thereof into the shape shown in Figures 18-20.

That is, the two shafts 10 and 12 are made of plastic material, the end of the outer shaft 10 being in the form of a cylindrical chamber 45 (thermoformed under vacuum or pressure) with a bottom 46 of essentially spherical shape. This cylindrical chamber 45 is
A plurality of annular rings 47 are provided on the outside thereof and terminate in a 20th circular oil painting portion 48 . This second cylindrical portion 48 has a smaller diameter than the cylindrical chamber 45 . This diameter difference is preferably equal to twice the wall thickness of the cylindrical chamber 45, which is the bulge.

The outer surface of the end cylindrical portion 48 also has one or more rings 49 formed therein.

Further, a stop portion 50 is formed between the two cylindrical portions 45 and 48. A soft conformator 51 is inserted into the chamber 45, which is the swollen portion below the stop portion 50. The conformator 51 has a central opening 52 formed at its bottom, and the inner diameter of the center opening 52 is equal to the inner diameter of the reduced diameter portion 48 . Inside the conformator 51, a polished heavy sphere 53 is accommodated. The diameter of this sphere 53 is made slightly smaller than the inner diameter of the conformator 51, and the opening 52
It rests on the 7th part around it and completely blocks this opening.

The sphere 53 has a grille 54 that closes the cylindrical part 48, while
The inner shaft 12 is formed at one end in the form of a second chamber 55, which chamber 55 has a base of approximately spherical shape and a cylindrical wall. An annular rib 56 is formed on this cylindrical wall at a distance from an edge 57. Then, when the chamber 55 of the shaft 12 is inserted into the cylindrical portion 48 of the shaft 100, the edge 57 of the chamber 55 abuts the stop 50, and the rib or ring 56 aligns precisely with the annular ring or projection 49. The combination is adapted to create an interconnection between 10 and 12. The connection between the bulges of two such shafts forms a continuous outer surface, which is provided with several annular protrusions 47,56, which allow the neck 3 of the balloon 2 to deform. The balloon neck 3 is held even when the balloon is exposed.

Thus, the air flowing through the interior of the jar 7) 10 and entering the opening 52 pushes the sealing sphere 53 up until it reaches the grille 54.

Air therefore passes through openings 52 and grilles 54 to inflate the balloon.

When the body 53 is no longer pushed up, the sphere 53 falls onto the aperture 52 of the conformator 51 and the counterpressure enclosed within the balloon forces this sphere 53 into the aperture 52.
Press firmly against the opening to ensure a complete seal. This seal can be improved even more effectively by coating each surface of sphere 53 and conformator 51 with a film of impermeable, non-oxidizing oil.

As a variant, the heavy sphere 53 can also be coated with a soft elastomer. In this case, there is no need to use the soft conformator 51.

A one-way valve device according to the invention can also be attached to the free end of the outer shaft 10 of the balloon.

According to the embodiment shown in FIGS. 21 and 22, the valve arrangement includes an outer sheath slider 58, which has a large diameter inlet end enlarged portion 59 and a precise end opposite this portion. and a bottom portion having a hole 60 formed therein.

A hollow cylinder 61, which is partially inserted into the slider 58, can slide. The upper end of this cylinder forms a sealing connection seat for the hollow shaft 10, while the lower end forms a circular stop 62 with a precisely formed hole 63. This stop 62 provides a stop in the upper portion of slider 58 around hole 60.

The interior of the enlarged end portion 59 of the slider 58 also forms a cylindrical cavity with an upper stop.

A hollow cylinder 64 is fitted into this space.'
It is. The hollow seven-cylinder cylinder 64 has a slightly tapered plug 65 on its upper surface, which has a rounded top and is coaxial with the axis of the hollow piston 61 and the opening 63. The upper surface of the sill 64 around the bottom of the Taber plug 65 includes several air inlet openings 6.
6 is drilled. The enlarged end portion 59 of the slider 58 is connected to a hose 67 of a suitable balloon inflator.

In the state shown in FIG. 21, since the Taber plug 65 is not inserted into the opening 63, air flows from the hose 67 in the A - + A direction without being obstructed by the blocking means 63-65. Flowing into the balloon. When the balloon is inflated to the desired inflation pressure, the slider 58 and therefore the cylinder 64 are pushed up by the supply air toward the piston 61 until the Taber plug 65 is inserted into the opening 63 of the stop 62. It will be done. At this time, since the piston 61 is made of a more elastic material than the Taber plug 65 and the slider 58, the stop portion 62 thereof deforms to some extent and sols the sheath slider 58 and the Taber plug 65, thereby causing the blocking means 6
3-65 7-rule is considered complete.

FIG. 23 shows a hollow shaft 10 made by drawing in such a shape that, in particular, the one-way valve device 1 improves the 21st and/or hole.

This/gift 10 has a middle part 10' of the thermoplastic material 10 which has a diameter larger than the outer diameter De.
It is said to be an enlarged part with .

This enlarged portion 10' is made according to this embodiment with an annular rib 68 of increasing diameter. Such extensions are needed in this field (as is known,
A draw bee of constant diameter is one that has sufficient local tension to apply sealing pressure.
