Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a brass instrument such as a trumpet or a phonophium tuba, and more particularly to a saliva storage container for a brass instrument that stores saliva collected in a valve switching device or moisture in exhaled breath.
[0002]
[Prior art]
The trumpet is provided with a rotary valve or a piston valve as a valve switching device, whereby the pipe length of the resonance tube is switched to generate a performance sound with different pitches.
[0003]
FIG. 2 shows a conventional example of a trumpet equipped with a piston valve. The trumpet 1 includes three piston valves 2 and is configured to switch a switching path provided in the piston body by pushing down the piston 3 with a finger. Reference numeral 4 denotes a tube main body of the trumpet 1, which is composed of a morning glory tube 4A, a blowing tube 4B, a main tube insertion / extraction tube 4C, and the like. 5 is a morning glory, 6 is a mouthpiece, 7A, 7B, and 7C are first, second, and third slides, 8 is a finger hook, 9 is a finger ring, and 10 is a water key.
[0004]
In such a trumpet 1, saliva accumulates in the tube body 4 and the piston valve 2 during performance. Moreover, when the moisture contained in the exhaled air is cooled, it becomes water. Of these, saliva accumulated in the tube main body 4 and moisture in the exhalation (hereinafter collectively referred to as saliva) are discharged from a saliva removal hole provided in the main tube insertion / extraction tube 4C. This hole is normally closed and is opened by the water key 10. On the other hand, saliva collected in the piston valve 2 is discharged from a saliva tube 13 provided on the bottom lid 12 that closes the lower end opening of the implantation tube 11. The spit tube 13 is always open.
[0005]
[Problems to be solved by the invention]
In the above-described conventional trumpet, since the spit tube 13 is always open, there is a problem that saliva falls on the floor during performance and is unsightly.
[0006]
Therefore, recently, in order to solve such a problem, a pipe 14 for preventing salivation as shown in FIG. 3 is attached to the spit tube 13 and saliva is accommodated in the pipe 14. Yes. The pipe 14 is made of metal, and a groove 15 is formed on a part of the peripheral surface over the entire length, and a keyhole-shaped insertion hole 16 communicating with the groove 15 is formed. It is designed to be plugged in. Similar pipes made of hard synthetic resin are also known. However, such a pipe 14 has the following problems and still has room for improvement. That is, since it has rigidity, when the piston valves 2 are not provided in a straight line, they cannot be installed structurally. Further, since the inside of the metal pipe cannot be seen, there is a problem that the saliva accumulation cannot be visually recognized from the outside.
[0007]
The present invention has been made to solve the above-described conventional problems. The object of the present invention is to be inexpensive and easy to manufacture, and to freely change the shape according to the arrangement of the valves. An object of the present invention is to provide a saliva storage container for brass instruments.
Moreover, this invention is providing the saliva storage container of the brass instrument which does not have the leakage of saliva.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a saliva storage container for a brass instrument for storing saliva discharged from a saliva tube provided on a bottom lid of a valve switching device, wherein the saliva tube is formed of a soft material on the peripheral surface. A cylindrical container body having a connection hole to be detachably inserted, a cap for liquid-tightly closing the opening end of the container body, and a moisture absorber accommodated in the container body. Features.
[0009]
In the present invention, the container body is formed of a soft material having elasticity and flexibility, such as synthetic resin and rubber, and is attached to the spit tube detachably by press-fitting the spit tube into the connection hole. When the container body is formed of a transparent synthetic resin, saliva accumulated inside can be visually recognized from the outside. Moreover, since it has flexibility, it can change a shape freely and can respond | correspond to the arrangement | sequence of a valve switching device. The water absorber absorbs saliva. The cap blocks the opening end of the container body in a liquid-tight manner to prevent saliva leakage.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.
FIG. 1 is a sectional view of a saliva storage container and a piston valve according to the present invention. Note that the same components as those shown in the prior art column are denoted by the same reference numerals, and description thereof will be omitted as appropriate. The saliva storage container 20 includes a container main body 21 that is formed of a soft material in a cylindrical body that is open at both ends, two caps 22 that close the openings at both ends of the container main body 21, and moisture stored in the container main body 21. And an absorber 23.
[0011]
The container body 21 is formed of a soft synthetic resin, rubber, or the like, and is formed so that three connection holes 24 are positioned on a straight line at the arrangement pitch of the piston valves 2 between the connection holes 24. The air vent hole 25 is formed in. The diameter of the connection hole 24 is substantially equal to the outer diameter of the neck 13a of the saliva tube 13 projecting from the lower surface of the back cover 12, and the saliva tube 13 is detachably press-fitted by the elasticity of the container body 21 itself. In this case, the spit tube 13 can be press-fitted even if the pitch of the piston valve 2 and the pitch of the connection holes 24 are slightly different, and can be used for products of other manufacturers. Further, since the container body 21 can be freely deformed in shape, depending on the arrangement of the piston valves 2, it is used by being bent into a V shape or an arc shape.
[0012]
The air vent hole 25 communicates with the inside and outside of the container main body 21 to facilitate the movement of the piston.
[0013]
The cap 22 is made of a synthetic resin. Since the container main body 21 is formed of a soft material, the cap 22 is in close contact with the inner peripheral surface when it is fitted to the opening end of the container main body 21 and is liquid-tightly closed.
[0014]
The moisture absorber 23 is formed of a material having high water absorption, such as polyester, cotton, or sponge. The moisture absorber 23 is so-called disposable and is replaced with a new one after a certain period of use.
[0015]
The saliva storage container 20 having such a configuration is assembled by storing the moisture absorber 23 in the container main body 21 and fitting the cap 22 to the opening end of the container main body 21. The tube 13 is detachably attached to the piston valve 2 by being press-fitted into the connection hole 24. In this state, saliva leaking from the spit tube 13 is absorbed by the moisture absorber 23. Therefore, saliva does not leak from the saliva storage container 20. Moreover, when the container main body 21 is formed of a transparent material, the saliva accumulation state can be visually recognized from the outside by the water absorption of the moisture absorber 23. Furthermore, since the container main body 21 is made of a soft material, it is less expensive than conventional metal ones, and can be easily bent and used according to the arrangement of the piston valves 2.
[0016]
In addition, although embodiment mentioned above showed the example applied to the brass instrument provided with the piston valve 2, this invention is not limited to this, It applies to the brass instrument provided with the other valve | bulb. Can do.
[0017]
【The invention's effect】
As explained above, according to the saliva storage container of a brass instrument according to the present invention, it is easy to attach to the saliva tube, the saliva does not leak, and the material cost is low. Can be used.
