Abstract

The balloon valve (10) has a cup-shaped valve body (12), from which a support body (48) projects with a radially outer support surface (52). The support surface (52) is spaced from the outer surface (18) of the valve body (12) and extending through the support body (48) through support passages (58). About the balloon valve (10) a balloon neck is slipped, which comes to rest with its collar in the groove (34). On the one hand, the balloon neck rests against the outer jacket surface (18) for closing the valve body passages (16) and, on the other hand, against the support surface (52). When filling the balloon, the filling medium flows, with expansion of the balloon neck, to the support passages (58) and through them into the interior of the balloon. There is achieved a significant reduction in noise, since the support body (48) prevents spreading of the resulting during filling oscillations of the balloon neck on the support surface (52) addition.

Description

  • The present invention relates to a balloon valve according to the preamble of claim 1 and to an automatic balloon machine and a balloon filling machine according to claims 13 and 14, respectively.
  • Balloon valves are well-known devices that make it possible to fill balloons by means of pressurized gases or liquids and then automatically close the balloons against a pressure loss. Balloon valves can be used for example in balloons for decoration purposes or as a toy for children or in weather meteorological balloons. The introduction of the balloon valves in the neck of the balloon and the filling, attaching and arranging the balloons are often complex and therefore costly steps.
  • A balloon valve is for example in the document US 3,616,569 disclosed. This balloon valve has a cup-like, closed by a bottom valve body on one side, the valve body shell forms together with an inner bottom surface an open valve body cavity on the input side. If the balloon valve is inserted in a balloon neck and the balloon valve is in an input-side depressurized state, then an outer jacket surface of the valve body jacket together with the balloon neck forms a sealing surface which prevents gas escaping from the interior of the balloon via the outer jacket surface. "Drucklos" designates a state in which the input side no pressure difference compared to the Ambient pressure of the balloon. The valve body shell is equipped with valve body passages extending from the valve body cavity to the outer jacket surface. The valve body passages are closed in the pressureless state on the input side by the sealingly fitting balloon neck, so that even in this way no gas can escape from the interior of the balloon into the environment.
  • If, on the input side, the opening of the valve body cavity is connected to a pressurized gas reservoir, this pressure acts on the balloon neck via the shell-side openings of the valve body passages. When the pressure reaches a value which causes the elastic balloon neck to lift off the sealing surface, the pressurized gas passes through the valve body passages and into a cavity formed between the outer surface of the valve body skirt and the inner surface of the balloon neck, across a sealing edge of the bottom of the balloon and fill it. By the gas flow along the membranous balloon neck are excited at this vibration. These vibrations can spread beyond the neck of the balloon to the entire balloon.
  • The vibrations of the balloon membrane are transmitted to the surrounding air and cause the formation of sound waves with often very high sound intensities in the frequency band that can be heard by humans. Typically, when filling balloons with known balloon valves, the sound level reaches over 100 dB, which is perceived by humans as very loud and unpleasant.
  • The object of the present invention is therefore to provide a balloon valve that generates the least possible noise pollution when filling a balloon, is simple and inexpensive to manufacture and can be inserted in an automated manner in a balloon neck and automated filling of the balloon allows ,
  • This object is achieved by a balloon valve according to claim 1, a balloon automat according to claim 13 and a balloon filling machine according to claim 14. Particularly preferred embodiments are equipped with the features listed in the dependent claims.
  • The balloon valve according to the invention is also equipped with a substantially cup-shaped valve body, which is closed on one side by a bottom. In this way, the interior of the valve body with its valve body shell and an inner bottom surface forms an open valve body cavity on the input side. The valve body shell has an outer lateral surface, which forms a sealing surface of the then self-closing balloon valve in cooperation with a balloon neck in the input-side pressure-free state. A valve body passage extends from the valve body cavity to the outer surface of the valve body shell.
  • According to the invention, from the valve body, preferably from an outer bottom surface of the valve body, a support body rises with an outer support surface, which is intended to abut the balloon neck. As a result, vibrations of the balloon neck that arise during the filling process of the balloon can not spread beyond the support surface on the entire balloon out and any vibrations of the balloon neck are attenuated. As a result, the noise load when filling the balloon is greatly reduced.
  • The support surface is preferably intended to abut at least almost sealingly on the balloon neck. Ideally, the balloon neck is fully sealing against the support surface.
  • So that the filling medium to be filled into the balloon, in particular gas, can freely penetrate beyond the outer jacket surface of the valve body into the interior of the balloon, the supporting body is provided with at least one support passage. This is on the one hand valve body side below the support surface and the other end output side, i. towards the interior of the balloon, permanently open.
  • The inventive balloon valve allows in addition to a noise-reduced filling and automatic closure of a balloon by its simple construction, a particularly inexpensive and cost-effective production. For example, the balloon valve according to the invention can be produced from a plastic in a single injection molding step. In addition, it is due to the freedom of design of its outer contours for automated insertion into a balloon neck and automated filling of a balloon very well suited.
  • Two particularly preferred embodiments of the balloon valve according to the invention are described in detail below with reference to a drawing. Purely schematically shows:

  • A particularly preferred embodiment of a balloon valve 10 according to the invention is shown in FIG Fig. 1 shown. This balloon valve 10 has a cup-shaped valve body 12 with a valve body shell 14. In the valve body shell 14 are six valve body passages 16, of which in the view in Fig. 1 only three openings with a circular cross section are visible, shaped. The valve body passages 16 extend in the radial direction from an outer lateral surface 18 in each case into an open, for example in FIG Fig. 3 visible valve body cavity 20. The valve body cavity 20 is formed substantially cylindrical and opened to an input side 22 out. Opposite the input side 22, the valve body cavity 20 is bounded on one side by an inner bottom surface 24 of a bottom 26. The bottom 26 thus closes the valve body 12 on one side.
  • The outer circumferential surface 18 of the valve body shell 14 is formed substantially annular and slightly tapered in the direction of the input side 22 tapered. It forms in cooperation with a balloon neck 28 of a balloon 30 at a pressure on the input side to the ambient pressure of the balloon 30 unpressurized state, a sealing surface 32. In other words, the balloon neck 28 is sealingly against the outer lateral surface 18 and prevented in the input-side unpressurized state outflow of a Gas from the balloon 30 through the balloon neck 28. The outer lateral surface 18 forms a valve seat and the balloon neck 28 a with this cooperating valve member.
  • On the valve body 12, the input side below the valve body passages 16, as in Fig. 3 shown, a circumferential groove 34 for receiving a collar 36 of the balloon neck 28, formed. In addition, two snap feet 38 are arranged with latching projections 40 on the input side of the valve body 12. The snap feet 38 form a receiving means for receiving an example in FIGS. 9 and 10 shown ring carrier 42 of a fastening device 44, which will be described in detail below.
  • The support body 48 is funnel-shaped and widens in the direction of an outlet side 50. On the outlet side in the free end region of the support body 48, a circumferential, radially outer support surface 52 is formed, to which such as in Fig. 3 shown, the balloon neck 28 enters an at least almost sealing contact.
  • The outer lateral surface 18 and the outer bottom surface 46 adjoin one another at a peripheral edge 53, which forms a sealing edge cooperating with its balloon neck 28. In the axial direction, therefore, the support surface 52 is spaced from this edge 46, ie from the outer lateral surface 18 and the bottom 28 or its outer bottom surface 48.
  • Inside the support body 48, a funnel cavity 54 is formed, the output side is open and the input side limited by the outer bottom surface 46. The outer cross section of the funnel-shaped support body 48 is smaller in the vicinity of the bottom 26 than the cross section of the bottom 26 and the outlet side outer cross section of the support body 48, thereby a radially around the support body 48 circumferential passage groove 55 is formed, which together with the balloon neck 28 a Cavity 56 limited. The cavity 56 is connected to the funnel cavity 54 through the support body 48 via six support passages 58. In the state of the balloon valve 10 inserted into the balloon neck 28, this causes the cavity 56 to be passively connected to the balloon interior via the support passages 58 and the funnel cavity 54.
  • The valve body 12, as well as the support body 48, has a substantially cylindrically symmetrical outer contour. Both bodies 12, 48 are arranged one above the other so that their longitudinal axes are coaxial with each other.
  • In the sectional view of Fig. 4 the inner structure of the balloon valve 10 with the cup-shaped valve body 12 and the substantially funnel-shaped or T-shaped support body 48 is shown. On the input side, the balloon valve 10 is in a pressureless state. Therefore, the balloon neck 28 sealingly abuts against the outer lateral surface 18 and the valve body passages 16 are closed on the balloon neck side. In addition, the balloon neck 28 is also sealingly against the support surface 52 of the support body 48. The annular cavity 56 is, over the support passages 58, pass-connected to the balloon interior.
  • Will now, as in Fig. 5 As shown on the inlet side of the balloon valve 10 applied a gas pressure, this causes a force on the balloon surface side openings of the valve body passages 16 on the balloon neck 28. As a result, lifts the elastic balloon neck 28 from the outer lateral surface 18, whereby pressurized gas into the cavity 56 can escape and pass through the support passages 58 and the funnel cavity 54 into the interior of the balloon. The occurring gas flow is highly abstracted by an arrow G in Fig. 5 indicated.
  • Also greatly simplified in Fig. 5 shown that the balloon neck 28 due to its elasticity and the ambient pressure against the support surface 52 and thereby suppresses propagation of vibrations of the membranous balloon neck 28 on the entire balloon 30. As already mentioned in the introduction, this reduces the noise level that arises when filling the balloon 30.
  • In Fig. 6 a further embodiment of the inventive balloon valve 10 is shown, in which the valve body 12 - this and the support body 48 are otherwise the same design as in the Fig. 1-5 shown and explained above - the input side is connected via a predetermined breaking point 60 with a pedestal 62. Between the pedestal 62 and the groove 34 are on the valve body 12 has four radially outwardly projecting Aufwickelbegrenzungen 64, of which Fig. 6 and Fig. 8 only two are visible, molded. The Aufwickelbegrenzungen 64 and extending to the pedestal 62 ring carrier 42 form a receiving means 68 for a fastening device 44, which, as in FIGS. 7 and 8 shown, for example, a wound on the ring carrier 42 and unwindable band 72 or a string comprises.
  • During the manufacturing process of the balloon valve 10, the band 72 is fastened to the ring carrier 42, preferably by gluing, then completely wound up and glued again to the preceding band winding at the end of the winding process. After insertion of the balloon valve 10 into the balloon neck 28 and the subsequent filling of the balloon 30, the pedestal 62 is separated at the predetermined breaking point 60 from the valve body 12 by breaking. The belt 72 can then be withdrawn and unwound from the ring carrier 42 opposite the take-up limits 64. As in Fig. 8 shown, the glued end of the belt 72 forms a loop 74 in the unwound state.
  • In the FIGS. 9 and 10 is another embodiment of a fastening device 44 for in the Figures 1 - 3 shown balloon valve shown. Here is the in Fig. 10 shown ring carrier 42 can be snapped onto the receiving means 68 formed by the snap feet 38. The separately producible ring carrier 42 is in each case equipped in its axial free end regions with four, opposite in pairs Aufwickelbegrenzungen 64. On the ring carrier 42 is also an unillustrated tape 72 or a string or unwound.
  • In the FIGS. 11-13 Further embodiments of fastening devices 44 are shown, which allow, in particular for decoration purposes, two opposing, as in the embodiment in Fig. 11 or four balloon valves 10 arranged in a rectangular shape, as in the embodiment in FIG FIGS. 12 and 13 to attach to each other via a snap connection. The fastening device 44 has fastening rings 70 'connected to one another via webs 70. At each ring a balloon valve with its snap feet 38 can be fastened. Of course, other forms of fastening devices 44, in particular for decorative purposes, conceivable in which a larger number of balloons 30 are held against each other via the attachment of their balloon valves 10 to the fastening device 44 in a predetermined position. Preferably, the already filled balloons are snapped onto the fastening device 44.
  • Balloon valves 10 according to the invention are preferably produced in one piece from a plastic in an injection molding process, preferably in a single injection process in each case. When using a plastic, the balloon valve 10 has a comparatively low mass, which accelerates an ascent of the balloon 10 by its improved buoyancy properties. In addition, a production in an injection molding process ensures a high production rate with relatively low production costs. Of course, it is also possible to use other materials, for example a light metal, for the production of the balloon valve.
  • In Fig. 14 a section of a balloon machine 76 is shown purely schematically. Balloon valves 10 according to the invention are mounted in a direction-defined manner in a magazine-like storage chute 78. In each case a balloon valve 10 is loaded from the storage chute 78 into an injection funnel 80 in an end region with a larger cross section. At the opposite end region of the injection funnel 80 with a smaller cross section of the balloon neck 28 of a balloon 30 is raised. The balloon valve 10 to be introduced is oriented in the injection funnel 80 in such a way that it can be introduced into the balloon neck 28 with its support body 48 leading into the balloon neck 28 while spreading the injection funnel 80. The balloon valve 10 is driven during insertion by a piston 82 which engages the input-side end of the balloon valve 10. As soon as the support surface 52 comes into contact with the balloon neck 28 when the balloon valve 10 is inserted, the balloon 30 is pushed down by the injection funnel 80. This process is simultaneously supported by an impact process by means of movable ejection vanes 84 arranged laterally on the injection funnel 80. The introduction of balloon valves 10 into a balloon neck 28 can be fully automated and performed at a high repetition rate.
  • In Fig. 15 a section of a balloon filling machine 86 is shown when filling an attached balloon 30 with a balloon valve 10. The balloon valve 10 is positioned centrally with its inlet side 22 on a filling head 88. The valve body cavity 20 of the balloon valve 10 is connected by means of an earring 90, the a discharge-side end portion of a filling valve 92 is arranged, sealed against the environment. If now the balloon valve 10 is pressed in the direction of the filling head 88, a pressure vessel (not shown) with a pressurized gas, for example helium, is opened and passage-connected via a filling valve passage 94 on the inlet side with the balloon valve 10. As a result, pressurized gas can flow along the in Fig. 15 drawn arrows G flow through the balloon valve 10 in the balloon 30. When the gas in the balloon has reached a desired pressure, the balloon 30 can be removed with the balloon valve 10 from the balloon filling head 88, whereby the gas pressure inside the balloon 30 due to the self-closing property of the balloon valve 10 is maintained in cooperation with the balloon neck 28. Like the introduction of the balloon valves 10 into the balloon neck 28, the filling of the balloon 30 can also be automated. Preferably, the balloon filling machine 86 is integrated in the balloon machine 78.
  • In addition to the previously described in detail forms of balloon valves 10 according to the invention with a funnel-shaped support body 48, of course, further embodiments of support bodies 48, for example with a T-shaped or umbrella-like longitudinal section are possible. It is crucial in each case that the support surface 52 abuts at least almost sealingly against the inner wall of the balloon neck 28 and thereby damps vibrations occurring during the filling process of the balloon neck 28, so that a propagation of these vibrations on the balloon neck 28 is suppressed to the remaining areas of the balloon 30 ,
