Description

The present invention relates to a blowback, and more particularly to a blowback that can be used for purposes such as health promotion, treatment, and cosmetology.

The party horn has long been known as a party horn toy. In this blowback, a linear body having elasticity like a wire is arranged along the longitudinal direction of the tubular stretchable body (bag-shaped portion), and one end of the tubular stretchable body is placed at one end of the stretchable body. At the other end of the dedicated pipe body, which is connected, a mouth blower is provided in which the user blows air in addition to the mouth. When air is blown from this mouth blower, the stretchable body is stretched, and in a state where air is not blown, the stretchable body is spirally wound by the elastic force of the linear body.

Such a party horn has traditionally been used primarily as a toy for children, but there are known party horns that can be used to perform breathing training for purposes such as health promotion, treatment, and beauty (eg,). See Patent Document 1). In this blowback, a mouthpiece made of an antibacterial flexible material is detachably provided in the blown portion, so that hygiene can be maintained well even after repeated use for a long period of time, thereby promoting health and promoting health. It is intended to be used for breathing training for the purpose of treatment, beauty, etc.

In the medical field, for example, such respiratory training includes prevention of pediatric asthma, lung cancer patients, patients undergoing surgery whose respiratory function has deteriorated due to preoperative and postoperative anesthesia, and environmental pollution such as PM2.5. It is performed for patients with respiratory dysfunction such as chronic obstructive pulmonary disease (COPD). In the field of long-term care, it is performed to prevent aspiration during meals or to rehabilitate swallowing by the elderly and persons with disabilities. In the field of cosmetology, it is performed to prevent the occurrence of nasolabial folds by strengthening the muscles of the cheeks. In the music field, it is conducted for the training of breathing and vocalization by vocalists and brass bands. In the field of sports, it is performed to increase the breathing power (exhalation power) such as sports blowing arrows.

By the way, since such blowback requires a predetermined blowing force (required expiratory force) because it is required to first stretch the stretchable body, sufficient air is blown into the stretchable body to stretch the stretchable body. In this state, the telescopic body, the dedicated tube body, and the mouth blower are filled with air, so that the required expiratory force required to maintain this state is not required so much. In other words, if the air was blown vigorously first, the rest could be maintained with a weak force.

However, in the blowback used for the purpose of health promotion and treatment, it is important to blow air for a certain period of time with a predetermined expiratory force, and in order to achieve such a purpose, the air inside the blowback is blown to the outside. Some of them are provided with air holes to allow air to escape (see Patent Document 2).

Utility Model Registration No. 3137944 Gazette Japanese Unexamined Patent Publication No. 2018-201883

However, in the case of a blowback provided with an air hole that allows the air inside to escape (exhaust) to the outside, the air leaks from the air hole at the beginning of the air blow, so that the stretchable body does not easily expand. was there.

In addition, it is known that the angle of the mouth decreases with aging, and it is necessary to train the orbicularis oris muscle to prevent the angle of the mouth from decreasing, so it is effective to strengthen the sucking force (inspiratory force). is there.

Therefore, according to the present invention, it is possible to smoothly perform the process from the start of blowing air to the extension of the stretchable body, and it is possible to blow air with a predetermined expiratory force for a certain period of time and to strengthen the inspiratory force. The purpose is to provide a possible blowback.

In order to solve the above problems, the invention of claim 1 comprises a tubular dedicated tube body, a tubular and deformable telescopic body provided on one end side of the dedicated tube body, and a tubular dedicated tube body and the other end of the dedicated tube body. It is provided with a mouth blower that is connected to the side and blows air in the mouth of the user. When the user holds the mouth blower and blows air, the stretchable body stretches, and if air is not blown, the stretchable body swirls. It is a blowback that is wound in a shape, and when the tip of the telescopic body is closed and an air hole that communicates the inside and the outside of the dedicated pipe body is provided, and the user blows air through the air hole. It is characterized in that it is formed at the position of the dedicated tube body to be gripped by a finger.

In the invention of claim 2, in the blowback according to claim 1, one end of an on-off valve made of a sheet-like member is connected to the vicinity of the air hole of the dedicated pipe body, and the on-off valve is connected to the air hole with a finger. The air hole is closed by pressing the air hole, and when the user blows air without pressing the on-off valve with a finger, the air is discharged from the air hole.

According to the third aspect of the present invention, a tubular dedicated tube body, a tubular and deformable telescopic body provided on one end side of the dedicated tube body, and a tubular dedicated tube body connected to the other end side of the dedicated tube body are held by the user. It is provided with a mouth blower that blows air into the mouth blower, and when the user holds the mouth blower and blows air, the stretchable body stretches, and if air is not blown, the stretchable body is swirled back. The tip of the telescopic body is closed, and an air hole for communicating the inside and the outside of the dedicated tube is provided, and the dedicated tube is gripped by the user when the user blows air. The air holes are opened and closed by a plug body made of a rubber-like material, and one end of the string body is connected to the plug body, and the other end of the string body is the tip of the stretchable body. Connected to the portion, the cord is characterized in that the plug is formed to a length that disengages from the air hole when the stretchable body is extended.

The invention of claim 4 is a tubular dedicated tube body, a tubular and deformable telescopic body provided on one end side of the dedicated tube body, and a tubular dedicated tube body connected to the other end side of the dedicated tube body, and the user can hold the body. It is provided with a mouth blower that blows air into the mouth blower, and when the user holds the mouth blower and blows air, the stretchable body stretches, and if air is not blown, the stretchable body is swirled back. Therefore, the tip of the telescopic body is closed, and an air hole for communicating the inside and the outside of the dedicated pipe body is provided, and the intake port has a size that cannot be sucked unless the hole diameter of the air hole is a desired intake force. It is characterized by the fact that it was done.

In the invention of claim 5, in the blowback according to claim 4, a cap body fitted to the air hole is provided, and the cap body is formed with a collar portion in contact with the outer peripheral edge of the air hole. It is characterized in that the intake port is formed at the same time.

The invention of claim 6 is characterized in that, in the blowback according to any one of claims 1 to 5, a phosphorescent paint or a fluorescent paint is applied to the tip of the stretchable body.

According to the invention of claim 1, since the tip of the telescopic body is closed and an air hole is formed at the position of the finger that grips the dedicated tube body, if the dedicated tube body is gripped when using blowback, the air hole is formed. Therefore, the stretchable body can be smoothly stretched without leaking the internal air from the start of blowing until the stretchable body is stretched, and after the stretchable body is stretched, the finger is pierced with an air hole. Since the air inside can be discharged to the outside by removing it from the air and opening it, a predetermined required expiratory force is required to maintain the stretched state of the stretchable body, and the air is aired at the predetermined expiratory force for a certain period of time. Since it becomes possible to blow in, it is possible to provide a blowback suitable for purposes such as health promotion and treatment.

According to the invention of claim 2, since the on-off valve that closes the air hole is composed of a sheet-like member, the user can continue to blow air by observing how the on-off valve floats when the air hole is opened. It is possible to judge whether or not it is allowed to do so. It can be determined that the user is continuing exhalation because the telescopic body does not rewind in a spiral shape, but when the telescopic body does not return well, the floating state of the on-off valve is observed. This makes it possible to judge whether or not the exhalation is sustained.

According to the invention of claim 3, the air hole can be opened and closed by a plug body, a string body connecting the plug body and the tip end portion of the stretchable body is provided, and the stretchable body is extended. Occasionally, since the plug body is formed to have a length that deviates from the air hole, the air hole is closed by the plug body to enable smooth extension of the stretchable body, and when the stretchable body is stretched, The plug body can be pulled by the string body to automatically open the air holes, and it is not necessary to artificially open the air holes at the timing when the stretchable body is extended.

According to the invention of claim 4, by making the intake port of the size of the air hole provided in the dedicated pipe body so that it cannot be sucked unless the intake force is desired, the blowback can be used as a training device for increasing the intake force. You can expect to train the orbicularis oris and not lower the corner of the mouth.

According to the invention of claim 5, since the collar portion of the cap body on which the intake port is formed is in contact with the outer peripheral edge of the air hole, the cap body is erroneously placed in the dedicated tube due to the intake force of the user. It is possible to surely prevent it from entering, and it is possible to prevent an accident of being sucked into the user's mouth.

According to the invention of claim 6, since the phosphorescent paint or the fluorescent paint is applied to the tip of the stretchable body, when the stretchable body is stretched, it can be made to shine even in a dark place, and it can be used like a penlight. Can be done.

Hereinafter, the present invention will be described based on the illustrated embodiment.

(Embodiment 1)
1 to 5 show a blowback 1 according to the first embodiment, FIG. 1 is a left side view, FIG. 2 is a plan view, and FIG. 3 is a plan view showing a state in which the telescopic body 2 is extended, FIG. Is a left side view showing a state in which the air hole is closed with a finger and air is started to be blown, and FIG. 5 is a left side view showing a state in which the stretchable body is extended.

The party horn 1 is a party horn that can be used for purposes such as health promotion, treatment, and beauty, and mainly includes a stretchable body 2, a dedicated tube body 3, and a mouth blower body 4. The blowing force (expiratory force) required to extend the stretchable body 2 is set in the blowing back 1 according to the purpose of use such as health promotion and treatment, the user's condition, and the like.

The stretchable body 2 is a tubular and deformable bag-shaped portion, which expands when air is blown into it and has a substantially circular cross section to be in an elongated state. When air is not blown into the stretchable body 2, it is wound in a spiral shape. It is configured in. The telescopic body 2 mainly includes a spiral portion 21, a linear body 22, a free end portion 23, and a connecting end portion (dedicated pipe body side end portion) 24.

The spiral portion 21 is a portion that is spirally or coiled by blowing air, and is made of a paper material having a predetermined thickness, strength, density (weight per unit area), durability, and other materials (characteristics). It is configured as a material, and its outer diameter is set to be slightly larger than the inner diameter of one end of the dedicated pipe body 3.

The length, thickness, etc. of the spiral portion 21 depend on the purpose of health promotion, treatment, beauty, etc. (purpose of use of the party horn 1), the oral function state of the user, the physical condition of the user, and the like. It is set. That is, the length of the spiral portion 21 is set so that the amount of air required to extend the spiral portion 21 becomes an appropriate amount of air preset according to the purpose, the user's situation, and the like.

The linear body 22 is made of a wire rod having elasticity and arranged straight along the longitudinal direction of the spiral portion 21, for example, a stainless steel wire, and is sandwiched between the paper materials of the spiral portion 21. .. Specifically, when the spiral portion 21 is manufactured, one strip-shaped paper material is bent in the width direction and the end edges are overlapped and glued. At that time, the linear body 22 is formed on the overlapping portion of both end edges. It is glued so that it is sandwiched. One end of the linear body 22 is fixed to the free end portion 23, and the other end is fixed to the connection end portion 24.

In a state where no external force is applied to the spiral portion 21 (a state in which air is not blown into the telescopic body 2), as shown in FIG. 1, the spiral body 22 is wound in a spiral shape or a coil shape by the elastic force of the linear body 22. When an external force is applied to the spiral portion 21 (air is blown into the elastic body 2), as shown in FIG. 3, the spiral portion 21 is in a straight stretched state, and when this external force is removed, the spiral portion 21 has a spiral shape. The elastic force that tends to return to the linear body 22 acts on the linear body 22.

In other words, the elastic force of the linear body 22 is such that the expiratory force required to extend the stretchable body 2 becomes an appropriate value set according to the purpose of use of the blowback 1 and the user's situation. The stretchable body 2 is set to a predetermined value so that the stretchable body 2 does not stretch unless the required expiratory force for blowing air from the body 4 is equal to or higher than an appropriate value (predetermined value).

As shown in FIG. 3, the free end portion 23 is the tip end when the stretchable body 2 is in an extended state. The free end portion 23 is a portion where the bag-shaped elastic body 2 is closed. For example, the adhesive tape is folded in the longitudinal direction and the folded end portion is coated with a phosphorescent paint. It is blocked by stopping at 23a. Further, when the free end portion 23 is folded, the end portion of the linear body 22 is also bent and fixed together.

By fixing the free end 23 of the stretchable body 2 with an adhesive tape 23a to which a phosphorescent paint is attached, when the stretchable body 2 is stretched, it can be made to shine even in a dark place, and can be used like a penlight. it can.

The connection end portion 24 is an end portion of the telescopic body 2 on the opposite side of the free end portion 23, and is a connection portion with the dedicated pipe body 3. At the connection end portion 24, the spiral portion 21 formed in a tubular shape is fitted onto one end of the dedicated pipe body 3 and fixed with, for example, an adhesive tape. At this time, the end portion of the linear body 22 is also fixed at the same time.

The air hole 25 is a hole for discharging the air blown into the telescopic body 2, the dedicated pipe body 3, and the mouth blower 4 to the outside, and as shown in FIG. 1, the upper portion of the dedicated pipe body 3 (FIG. The position of the finger (for example, the index finger) F to be pressed from above or its vicinity in the state where the user is grasping the dedicated pipe body 3 from above and below and trying to blow air in addition to the mouth blower body 4). Is formed in.

The position of the air hole 25 is, for example, when the length from the end of the mouth blower 4 to the connection end 23 of the dedicated pipe body 3 is 10 cm, the distance from the end of the mouth blower 4 to the air hole 25 is It is preferably 5 to 8 cm and, as described above, provided on the upper part when the dedicated pipe body 3 is held. The distance from the end of the mouth blower 4 is the distance from the mouth during use, and is a comfortable distance for moving a finger to open and close the air hole 25. Further, the reason why it is provided on the upper part of the dedicated tube 3 is that it is stable to support the thumb T from below and the index finger F and the middle finger from above when gripping the dedicated tube 3, and two fingers from above. This is because when the air hole 25 is opened and closed by the index finger F, the index finger F is moved, so that the other middle finger and the thumb T need to support the dedicated tube body 3.

The reason why the air hole 25 is provided will be described. In the conventional party horn, the breath (air) is blown vigorously first, and when the stretchable body is filled with air, no more air can be blown. By the way, for the purpose of promoting health and treatment, it is necessary to have a continuous blowing force (continuous expiratory force), and it is important to blow air with a predetermined expiratory force for a certain period of time even in the blowback.

Specifically, it is effective to spend twice as much time as inhaling when breathing to exhale air and blow air into the blowback. Therefore, by discharging the air blown into the telescopic body 2 from the air hole 25, it is possible to blow the air with a predetermined expiratory force for a certain period of time. The air holes 25 are set so that a predetermined amount of air is discharged to the outside according to the purpose of use and the user's situation, such as respiratory treatment, swallowing rehabilitation, and training in breathing method and vocalization method. ..

The dedicated pipe body 3 is a place where the user grips the blowback 1, and is a cylindrical body connected to the connection end portion 24 of the stretchable body 2 and formed in a substantially cylindrical shape with a thick paper material having a predetermined material. .. The dedicated pipe body 3 includes one end portion (one end side of the dedicated pipe body) 31 which is the end portion on the telescopic body 2 side, and the other end portion (the other end side of the dedicated pipe body) 32 which is the end portion on the mouth blower 4 side. One end 31 is inserted into the connecting end 24 of the stretchable body 2 and connected with vinyl tape or the like. The inner diameter and length of the dedicated pipe body 3 are set so that the user can easily hold the dedicated pipe body 3 and air can be easily blown from the mouth blower body 4 to the expansion / contraction body 2.

The mouth blower 4 is a place where the user blows air in addition to the mouth, and has a substantially cylindrical shape and is connected to the other end 32 of the dedicated pipe body 3. The mouth blower 4 is made of, for example, a plastic resin or the like. It should be noted that, for example, a mouthpiece for improving the grip of the user and maintaining a good hygiene even after repeated use for a long period of time is freely attached to the mouth blower 4.

In the blowback 1 having the configuration shown in FIGS. 1 to 3, when the user blows air from the mouth blower 4, the air flows into the stretchable body 2 and the stretchable body 2 stretches, and in a state where the air is not blown, FIG. As shown in 1, the elastic force of the linear body 22 causes the stretchable body 2 to rewind in a spiral shape. At this time, the stretchable body 2 is stretched unless the required expiratory force for blowing air from the mouth blower 4 is equal to or higher than an appropriate value (predetermined value) set according to the purpose of use such as health promotion and treatment and the user's condition. It is configured so that the stretchable body 2 does not stretch to the maximum unless it is continued and only a preset amount of air is blown according to the purpose of use such as health promotion and treatment and the user's condition.

How to use the party horn 1 will be described.

First, the user grips the dedicated tube 3 of the party horn 1 so as to be sandwiched between the index finger F and the thumb T from above and below. At this time, the index finger F is used to close the air hole 25.

Next, air is blown from the mouth blower 2. The blown air inflates the spiral portion 21 and extends the spiral portion 21 against the elastic force of the linear body 22 (see FIG. 4). Since the free end portion 23 of the spiral portion 21 is securely closed with the adhesive tape 23a, air does not leak from the free end portion 23, and the spiral portion 21 swells and expands reliably and efficiently. Become.

Here, if the air hole 25 is opened at the beginning of blowing air, the air blown into the blowback 1 leaks from the air hole 25, and the stretchable body 2 does not easily extend. In particular, in the case of the party horn 1 for long-term care, since the user is old, the expiratory power is weak and the stretchable body 2 tends to be difficult to stretch. Therefore, by closing the air holes 25, even an elderly person can easily and efficiently extend the stretchable body 2.

When the stretchable body 2 is stretched, that is, when it becomes impossible to blow air, the index finger F is moved to open the air hole 25 (see FIG. 5). As a result, air is discharged from the air hole 25, so that the air can be continuously blown while maintaining the state in which the stretchable body 2 is stretched to the maximum, and the exhalation state is maintained. At this time, the amount of air leaking from the air hole 25 is small, and by continuing the exhalation as it is, the stretchable body 2 does not rewind.

When the expiratory force decreases in the expiratory state, the air in the spiral portion 21 further leaks from the air hole 25, the internal pressure decreases, and the elastic force of the linear body 22 exceeds this internal pressure, and the stretchable body 2 Will rewind.

As described above, such blowback 1 can be used for respiratory treatment, swallowing rehabilitation, training of breathing method and vocalization method, etc., and also measures the duration of exhalation to measure the cardiopulmonary system of the user. It can also be used as an exhalation duration measuring device to measure ability.

When measuring the exhalation duration, the time is measured from the time when the stretchable body 2 is extended or when the air hole 25 is opened, and when the exhalation cannot be sustained, the measurement of the exhalation duration is completed. To do.

When using the exhalation duration measuring device, it is necessary to use the party horn 1 under the same conditions, and the conditions include the shape (length, thickness, etc.) of the elastic body 2 and the dedicated tube body 3. The elastic modulus of the linear body 22, the size of the air holes 25, the number of air holes 25, and the like are factors.

Further, when the party horn 1 is used as a training device for expiratory force, it is conceivable to form a large air hole 25 for a vocalist or a brass band player, or to make the air hole 25 smaller for an elderly person.

In any case, it can be configured so that air can be blown for a certain period of time with a preset expiratory force according to the purpose of use such as health promotion and treatment and the user's situation. Therefore, by repeating the expansion and contraction (blowback) of the stretchable body 2 using such a blowback 1, exercise and training with an appropriate required expiratory force according to the purpose and the user's situation can be performed. ..

As described above, according to the blowback 1 according to the first embodiment, the free end portion 23 of the spiral portion 21 is surely closed, and the air hole 25 is provided in the dedicated pipe body 3, and the telescopic body 2 is provided. When extending, the air hole 25 is closed with the index finger F to prevent air leakage, so that the extension can be performed smoothly and efficiently. Then, after the stretchable body 2 is stretched, the air holes 25 are opened and air is gradually discharged, and in order to maintain the stretched state, depending on the purpose of use such as health promotion and treatment and the user situation. It is necessary to blow air for a certain period of time with a preset expiratory force. In the first embodiment, the air hole 25 is provided in the upper part of the dedicated pipe body 3 and the opening and closing is performed by the index finger F, but the present invention is not limited to this and is in the lower part of the dedicated pipe body 3. An air hole may be provided and the air hole may be opened and closed with the thumb T.

As a result, it becomes possible to blow air with a predetermined expiratory force for a certain period of time, so that it is possible to provide a blowback 1 suitable for purposes such as health promotion and treatment. In addition, the air holes 25 are set so that a predetermined amount of air is discharged to the outside according to the purpose of use and the user's situation, such as respiratory treatment, swallowing rehabilitation, and training in breathing method and vocalization method. Therefore, it becomes possible to provide a blowback suitable for the purpose of use.

(Embodiment 2)
6 and 7 show the party horn 1A according to the second embodiment, FIG. 6 is a left side view, and FIG. 7 is a plan view. The blowback 1A according to the second embodiment is different from the blowback 1 according to the first embodiment in that an on-off valve 41 is provided in the air hole 25. The description will be omitted by assigning the same reference numerals.

The on-off valve 41 is made of, for example, a rectangular paper material, and one end edge is glued to a position slightly closer to the mouth blower 4 side than the air hole 25A of the dedicated pipe body 3, and the other end side is separated from the outer surface of the dedicated pipe body 3. It is possible to contact.

Then, when the user blows air into the blowback 1A, the air hole 25A is closed by pressing the air from the upper side of the on-off valve 41 with the index finger F. As a result, the spiral portion 21 can be extended by blowing air into the party horn 1A, as in the case of the party horn 1 according to the first embodiment.

When the spiral portion 21 is extended, the index finger F is moved to release the pressure on the on-off valve 41, and the air of the blowback 1 pushes away the on-off valve 41 and is discharged from the air hole 25A.

When air is discharged from the air hole 25A, the on-off valve 41 made of a relatively fragile material has its other end lifted from the upper surface of the dedicated pipe body 3 and spirals while the user continues to blow air. While maintaining the extended state of the portion 21, the other end of the on-off valve 41 is lifted from the upper surface. Although the on-off valve 41 of the first embodiment has been described as being made of a paper material, any sheet member made of a relatively soft synthetic resin material such as a so-called vinyl soft plastic may be used. .. In short, it may be any one that flexibly deforms when air is discharged from the air hole 25.

As described above, according to the blowback 1A, since the air hole 25A is provided, the same effect as that of the first embodiment can be obtained, and since the on-off valve 41 is provided, the on-off valve 41 is lifted. By looking at the side, even a third party can judge whether or not the user keeps blowing air.

It should be noted that a third party can determine that the user continues to exhale because the stretchable body 2 does not rewind in a spiral shape, but this is the case when the stretchable body 2 does not return well. Even in such a case, it can be determined by observing the floating state of the on-off valve 41.

(Modification example)
FIG. 8 is an enlarged plan view showing a modified example of the blowback 1A according to the second embodiment, and specifically, is a modified example of the on-off valve 41.

The on-off valve 42 of this modified example is formed by providing a plurality of slits extending in the longitudinal direction in the on-off valve 41 to form a plurality of strips 42a.

According to the on-off valve 42 of this modified example, when the air is discharged from the air hole 25A, the way of lifting each strip 42a differs due to the difference in the air pressure received by each strip 42a, so that the movement of each strip 42a moves. It will be separated and will be easier to understand than how the on-off valve 41 of the second embodiment is lifted.

(Embodiment 3)
9 and 10 show the party horn 1B according to the third embodiment, FIG. 9 is a plan view, and FIG. 10 is an enlarged cross-sectional view taken along line XX in FIG.

Comparing the blowback 1B according to the third embodiment with the blowback 1A according to the second embodiment, the opening and closing valve 41 provided in the air hole 25A is different in that the on-off valve 41 is made of a thin plate. The same reference numerals are given to the configurations equivalent to the above, and the description thereof will be omitted.

The on-off valve 43 of the third embodiment is composed of a rectangular thin-walled synthetic resin plate, and one end edge is connected to a position slightly closer to the mouth blower 4 side than the air hole 25B of the dedicated pipe body 3, and the other end side is connected. It can be separated from the outer surface of the dedicated pipe body 3.

The on-off valve 43 is made of a material slightly harder than the paper material such as the on-off valve 41 of the second embodiment, and is connected in a curved shape along the outer peripheral surface of the dedicated pipe body 3. Therefore, the other end is difficult to lift (see FIG. 10). The slightly hard material is, for example, a slightly hard synthetic resin material, a thin metal plate, or the like.

Therefore, in the blowback 1B according to the third embodiment, there is little air leakage even if the on-off valve 43 is not pressed with a finger when the telescopic body 2 is stretched by blowing air, and therefore, the stretchable body 2 is stretched and contracted. Body 2 can be stretched. This is because the slightly rigid on-off valve 43 is curved along the outer peripheral surface of the dedicated pipe body 3, and even when air is blown in, the other end side of the on-off valve 43 is slightly lifted. Since the amount of discharge is small, the stretchable body 2 can be sufficiently stretched.

Then, when the telescopic body 2 expands, the internal pressure in the telescopic body 2 increases due to the continuation of exhalation, the other end of the on-off valve 43 slightly rises from the outer peripheral surface of the dedicated pipe body 3, and the air comes from the air hole 25B. It will be discharged.

As described above, according to the blowback 1B, since the air hole 25B is provided, the same effect as that of the first embodiment can be obtained, and the on-off valve 43 is made of a thin plate, so that the telescopic body can be obtained. The telescopic body 2 can be extended without pressing the on-off valve 43 until the 2 is extended.

Since the party horn 1B according to the third embodiment requires a relatively strong expiratory force in order to be lifted in the opening direction of the on-off valve 43, a training blow for strengthening the expiratory force is required. Used as party horn 1B.

11 to 13 show the blowback 1C according to the fourth embodiment, FIG. 11 is a left side view showing a state in which the stretchable body has begun to stretch, and FIG. 12 is a left side view showing a state in which the stretchable body 2 has stretched. FIG. 13 is an enlarged vertical sectional view of a main part of FIG. 11.

Comparing the blowback 1C according to the fourth embodiment with the blowback 1 according to the first embodiment, the configuration is the same as that of the first embodiment, except that the blowback 1C is provided in the plug 51 that closes the air hole 25C. The description of the above will be omitted by assigning the same reference numerals.

The plug body 51 is made of a rubber-like material, and is composed of a columnar plug portion 51a that is substantially fitted in the air hole 25C and a flange portion 51b formed on one end side of the plug portion 51a.

One end of the string body 52 is fixed to the flange portion 51b of the plug body 51, and the other end of the string body 52 is fixed to the free end portion 23 of the telescopic body 2.

The length of the string body 52 is formed to be slightly shorter than the length of connecting the free end portion 23 in the extended state of the stretchable body 2 and the flange portion 51b of the plug body 52 closed by the air hole 25C. ..

As a result, when the stretchable body 2 is stretched and stretched while the plug body 52 is fitted in the air hole 25C (see FIG. 11), the plug body 51 is pulled by the string body 52 and comes out of the air hole 25C. (See FIG. 12).

A ring guide 53 having a small diameter is provided at a position slightly closer to the telescopic body 2 side than the air hole 25C of the dedicated pipe body 3, and the string body 52 is passed through the ring guide 53 from the air hole 25C. The protruding plug body 51 is hooked on the ring guide 53 (see Fig. 12). Therefore, it is possible to fit into the air hole 25C and close the air hole 25C without searching for the plug 51 when the air is blown again.

In such a method of using the plug body 51, the plug body 51 is fitted into the air hole 25C before the air is blown into the blowback 1C, and the air hole 25C is closed. At this time, the stretchable body 21 is spirally rewound, and the string body 52 is also spirally wound around the rewound stretchable body 2.

When air is blown into the blowback 1C in this state, air is smoothly blown into the stretchable body 2 because the air hole 25C is closed, and the stretchable body 2 is stretched.

When the stretchable body 2 is fully extended, as described above, the string body 52 pulls the plug body 51 fitted in the air hole 25C, and the plug body 51 escapes from the air hole 25C to open the air hole 25C. ..

As a result, even after the stretchable body 2 is stretched, the user can continue to blow air, and the air is discharged from the air hole 25C while maintaining the internal pressure of the stretchable body 2.

As described above, according to the blowback 1C according to the fourth embodiment, the air hole 25C provided in the dedicated pipe body 3 can be completely closed by the plug body 51, so that the expansion / contraction body 2 can be smoothly extended. Further, when the stretchable body 2 is stretched, the plug body 51 is pulled by the string body 52 to automatically open the air hole 25C, so that the finger is aligned with the stretched timing of the stretchable body 2 as in the first embodiment. It is not necessary to release the blockage of the air hole 25 due to the above.

14 to 15 are enlarged vertical sectional views showing a main part of the blowback 1D according to the fifth embodiment, and FIG. 14 shows a state before attaching the cap body 61 to the air hole 25D of the dedicated pipe body 3. FIG. 15 shows a state in which the cap body 61 is attached to the air hole 25D.

In the blowback 1D according to the fifth embodiment, in order to train the orbicularis oris muscle, the user can train the suction force by holding the blowback 1D in the mouth and sucking air.

Comparing the blowback 1D according to the fifth embodiment with the blowback 1 according to the first embodiment, the configuration is the same as that of the first embodiment, except that the cap body 61 that closes the air hole 25D is provided. The description of the above will be omitted by assigning the same reference numerals.

The cap body 61 is made of a rubber-like material and is composed of a cylindrical body portion 61a that is substantially fitted in the air hole 25D of the dedicated pipe body 3 and a flange portion 61b formed on the upper end side of the body portion 61a. The central hole of the is an intake port 62.

The body portion 61a of the cap body 61 is fitted into the air hole 25D of the dedicated pipe body 3 from above, the collar portion 61b is brought into contact with the outer peripheral edge of the air hole 25D, and the cap body 61 is attached to the dedicated pipe body 3. As a result, the inside of the expansion / contraction body 2, the dedicated pipe body 3, and the mouth blowing body 4 of the party horn 1D is communicated with the outside through the intake port 62 of the cap body 61.

Then, when the user sucks in air in addition to the mouth blower body 4 of the party horn 1D, the outside air flows in from the intake port 62 of the cap body 61 and can suck in the outside air, and at this time, the orbicularis oris muscle is trained. become.

Further, when the user sucks air from the intake port 62 by the intake force, the cap body 61 has the collar portion 61b in contact with the outer peripheral edge of the air hole 25D, so that the cap body 61 is brought into contact with the outer peripheral edge of the air hole 25D by the intake force of the user. It does not enter the dedicated tube body 3, and it is possible to prevent an accident in which the cap body 61 is accidentally sucked into the user's mouth.

The hole diameter of the intake port 62 is formed to a size that can be sucked only by a desired intake force. For example, the cap body 61 is prepared with an intake port 62 having a hole diameter of 2 to 5 mm, and a young person who wants to train the orbicularis oris muscle more has a small hole diameter (2 mm), and an elderly person or the like is compared. A large hole diameter (5 mm) will be selected and used.

As described above, according to the party horn 1C according to the fifth embodiment, the user's orbicularis oris muscle is trained by selecting the cap body 61 of the intake port 62 having an appropriate hole diameter according to the physical strength of the user. be able to.
