The present invention relates to an assembling structure in which an aerosol container is assembled to a dispenser having a speed reducer chamber in which an aerosol container can be piped during transportation, and the deceleration chamber is opened by removing the container in the container case. And an aerosol dispenser configured to pivot the assembly structure relative to the deceleration chamber so that the assembly can be secured in a rigid position so that the medicine in the aerosol container can be conveniently administered.

Therapeutic aerosol dispensers have been known to administer small particles to be inhaled into the lungs as a dosage measuring device. A certain amount of dosage is very desirable.

Inhalation therapy is mainly used in visually impaired, elderly, weak, or busy people, so that the inhalation therapy is mainly used in poorly lit conditions, i.e., at a time that adversely affects the visual and nervous system, thus the operation is simple and 1 There is a need for a dispenser with a structure that can only be assembled in a certain way of branches.

That is, it is desirable that all parts are integrally joined so that there is a risk of misplaced parts during use. As an example, consider the use of this dispenser in a patient with asthma symptoms that are difficult to control himself. The patient will try to take asthma medicine very quickly whenever they have symptoms of asthma.

If the operation is very complicated, such as assembling the dispenser for administration, it can be very sad for this patient.

FIG. 1 shows the aerosol dispenser according to the present invention, bent from the body to administer a drug suspended in the aerosol propulsion proposal. FIG. 2 shows the aerosol dispenser in a pocket or purse until the next use. For example, a form in which an aerosol dispenser is inserted into a body is shown. In Figure 2, a part of this folded form is shown in cross section, so that the various accessories are particularly clearly shown.

The cylindrical body 11 exhibits two functions, namely, serves as a carrier of the cylindrical container during transportation, and serves as a deceleration chamber when used. An end wall 12 is formed at one end of the cylindrical body 911, and a blowout port 13 is formed in the end wall 12. At the time of storage, the spray outlet stopper 14 is covered with the spray opening 13 to prevent dust from entering the contents of the dispenser. The jet plug 14 can be fitted inside or outside the jet port 13, and preferably has a size small enough to suit its function. This is not necessary, but usually the diameter of this cylindrical body Inch, length about About an inch and the diameter of the spout It's good to be around inches. Of course, this size is not essential. The spout should be large enough to fit the mouth of the person using it, whether the user is a child or an adult. The size of the deceleration chamber must be large enough to accept the dispensed medicine to sink the large particles and completely dissipate the entire contents of the charge, but on the one hand it must be small enough to fit in the user's pocket. It must have a size.

There is a piston stop 15 near the opposite end of the free barrel body 11. At least one piston stop is required and two are shown in the figure but may be installed in any number. It is helpful to control the position of the piston by pitting the cylinder wall to form a piston stop so that the piston is caught inside the cylindrical body and stopped. The body extension 16 is attached to the body and extends out of the body in a short length. The body extension 16 has a diameter slightly larger than the diameter of the cylindrical body itself, and the support of the large case flange 32. Will act as). Usually, the cylindrical body 11 and the end wall 12, the ejection port 13, the piston stop 15 and the body extension 16 are molded by casting a single plastic piece in a suitable injection molding, in which the body is cast. The piston stop may be formed after the casting is completed in order to more easily remove the mold that is fitted inside the body.

Inside the cylindrical body 11 there is a piston 17. The piston is slightly smaller than the cylindrical body and is located in the cylindrical body so that it can slide in the body. The piston skirt 18 is tightly fitted inside the cylindrical body 11 and has a sufficient length so that the piston 17 does not incline obliquely in the cylindrical body. At this time, the length of the piston skirt 18 is approximately If it is enough, a favorable control effect can be exhibited. In addition, a friction rail 19 is cast outside the piston skirt and slides inside the cylindrical body, thereby minimizing friction. The size of the piston skirt is slightly smaller than the size of the cylindrical body 11, the friction rail 19 is protruding so that air can pass between the piston skirt 18 and the cylindrical body 11 of the present invention When using the dispenser it serves as a source of dilution air.

In addition, when the friction rail 19 is used, the piston is loosely fitted to the cylindrical body 11 so that the cylindrical body 11 may have a form in which the end is slightly open. Although not functionally desirable, a problem arises in that the manufacturing cost is very high during casting unless the cylindrical body is formed so that the end of the cylindrical body slightly opens. By allowing this tip to open very little, the casting pin can be easily pulled out of the cylindrical body. It is very common in the casting industry to use a slightly conical body rather than an exact cylinder. In all possible cases, the molded plastic parts are thus designed to be slightly open. Surprisingly, the use of friction rails allows the ends to be wide enough to be inexpensive in manufacturing and convenient in use.

In the piston skirt 18, a split groove 20 is also formed. Since the dividing groove 20 is designed to work together with the piston stop point 15, the piston can be inserted into the cylindrical body by screwing the piston 17 until the dividing groove coincides with the piston stop point during assembly. At this time, if the piston 17 is only slightly turned, the piston will not come out unless the split groove is exactly matched with the piston stop point. In normal use, this piston is pulled until the piston reaches the piston stop, which is supported in the rearmost operating position.

The piston head 21 partially covers the rear end of the piston. There is an overlapping sleeve 22 in the lateral direction of the piston head 21. Two superimposed sleeve arms 23 extend rearward from the sleeve body, and two support bolts 24 having heads are positioned toward the rear end of the sleeve arms 23. These support bolts are located inward facing each other, and are used as pivot axes of the container case 26 to be described later. If a head such as a nail head is formed in the support bolt, the support bolt can only be inserted or retracted from the enlarged portion of the bolt groove 28 to be described later.

At one end of the sleeve 22 between the nested sleeve arms 23 there is a wing alignment slot 25.

The container case 26 is telescopically nested within the overlapping sleeve 22. This container case is large enough to contain the aerosol container 27 and to be sealed. The tip of the container case can slide in the overlapping sleeve. During storage, the container case fits well into the inner side of the nested sleeve. This allows a space to be secured so that a relatively large aerosol container 27 can be obtained even in a dispenser having a size that fits in a pocket. . There are bolt grooves 28 on both sides of the container case 26, and bolt insertion holes 29 are provided at the rear end of the bolt groove. When the support head 24 having the head is formed is assembled to the overlapping sleeve arm 23, the support bolt is fitted through the bolt groove so that the container case can be telescopically superimposed on the overlapping sleeve during storage. It also allows the container case 26 to withdraw to the dosing position when administering medication. The bolt insertion hole 29 allows the container case to be assembled in the overlapping sleeve and prevents them from being accidentally disassembled. There is a container case 30 having a larger diameter about halfway in the longitudinal direction of the container case 26, thereby preventing the container case from being excessively deeply inserted into the overlapping sleeve. The container case 30 is radially in contact with the end of the overlapping sleeve arm in the forward position.

There is a case base 31 at the rear of the container case and a case flange 32 around the outside of the case base. The case flange 32 has a substantially cylindrical shape, so that the body extension portion during transportation 16) to slide in. At this time, the case flange is sized to fit tightly to the body extension, so closing it effectively seals the rear end of the assembly to prevent dust from entering.

The case base 31, the container case 26, and the case flange 32 have two gripping grooves 33, so that the aerosol container 27 inserted into the container case can be pulled out of the case with a finger.

At the tip of the case, there is a case head 34 having a spray nozzle 35. A spray hole 36 connected to the spray nozzle at right angles to the axis of the case is formed in the spray nozzle. The actuation tube aperture 37 receives actuation tube 38 which actuates the valve 39 on the aerosol container 27. The valve 39 of the aerosol container uses a conventional dosage valve that acts axially as is well known in the art. In addition, as a part of the case head 34, a ground portion 40 is formed, which is a part where the user's finger touches when the container is pressed into the case, and the nozzle side of the container case extends upward. have.

This grounding portion is integrally formed with a spray indicating blade 41, which indicates the direction of the spray hole 36, and serves to prevent the case from bending backward with respect to the sleeve, together with the grounding portion, When the container case is bent against the overlapping sleeve, the spray nozzle is oriented so that it only points in one direction. This wing also extends high so that, when bent to the dosing position, the spray-instructing wing 41 is fitted into the wing alignment slot 25 to prevent the container case from twisting laterally with respect to the nested sleeve. It serves as a direction indicator.

In the lower part of the nozzle in the same direction as the above-described grounding part 40, there is a case support part 42 to prevent the overlapping sleeve from bending over 90 ^° with respect to the container case, so that the spray nozzle is in the cylindrical position at the dosage position. The spray nozzle is fixed to the side of the nested sleeve arm and the container case so as not to rotate excessively by the case support and the nested sleeve.

During storage, the spout stopper 14 is fitted to the spout to prevent dust from entering through the distal end of the dispenser, and the rear end is sealed by the action of the case flange 32 and the body extension 16 to prevent dust and contaminants from penetrating. This dispenser is safe even in your pocket.

In use, this spout cap is removed, even if the cap is lost, there is no problem in administering the drug. The other parts are unlikely to disassemble, so the risk of their loss is negligible. Pull the case flange backwards until the piston reaches the piston stop, and at this point the container case is bent in only one direction, and if it is bent to 90 ^o , the spray holes 36 are aligned with the cylindrical body. Along the axial direction of the cylindrical body is sprayed into the cylindrical body. By fixing the spray instructing blade 41 in the blade alignment slot 25 to prevent the axial movement, axial stability is obtained. Thus, the dispenser gives a solid feeling at the time of administration, so that the user can open the aerosol container 27. It is much easier to press against the working tube hole, whereby a uniform single dose is administered inside the cylindrical body.

Since the cylindrical body 11 and its short wall 12 and the piston 17 in the retracted position form a immersion chamber, the sprayed medicament stops and the large particles stick to the wall of the deceleration chamber for uniform administration. Thus, convenient suction from the deceleration chamber is achieved.

When the aerosol container 27 is emptied, it can be taken out and solidified into a filled aerosol container, so that the aerosol dispenser can be reused while continuing to refill the aerosol container.

The aerosol dispenser and all other components are suitably cast from plastics such as polyethylene or polypropylene. If cast parts such as nested arms are made of isotactic polypropylene or high-density polypropylene, and the tape is cast from similar polypropylene, the service life of the dispenser is greater than that of soft plastics. This will be longer. The thickness and ratio of the walls can be converted according to the manufacturer's intention. Since most parts except the spray nozzle and case head have roughly the same thickness, it is very convenient to manufacture them and a good dispenser can be produced at a fairly low cost even with conventional casting techniques.

All parts are pivotally connected and can also be pulled out of the gripping grooves even if they are not firmly grasped by the thumb and forefinger, so the dispenser of the present invention can also be used by a person whose physical function is impaired by asthma or other symptoms. Therefore, even if the patient who needed a person to take the drug when administering the drug as a conventional device, the device of the present invention can be safely used by the patient himself.

As such, the dispenser of the present invention can be used much more quickly under conditions that impair body function or motor nerves, and even a very inexpensive device is much more dangerous in handling or making mistakes than any device ever considered practical. Can be reduced.
