Description

  The present invention relates to an adapter for an aerosol injection device and an aerosol injection device.

Conventionally, dirt in drain pipes such as kitchens and bathtubs has been removed by inserting a long wire with a brush at the tip into the drain pipe and rubbing the dirt directly. There is a demand for a method that can easily remove the dirt in the drain pipe because it takes time and effort. On the other hand, a method using aerosol is proposed as a method for easily removing dirt on the drain pipe (see, for example, Patent Document 1). In this method, for example, as disclosed in Patent Document 1, the cap is formed in a hemispherical shape larger than the inner diameter of the drainage port, and the hemispherical cap is brought into contact with the drainage port of the drainage pipe. By doing so, the contents having the cleaning component are sprayed into the drain pipe to remove the dirt in the drain pipe.
Japanese Utility Model Publication No. 57-51775

  By the way, in a wash basin generally installed at home, a drain plug is installed so that a drain outlet can be closed and water can be stored. While this drain plug is located above the drain port when not in use, the drain plug is lowered to plug the drain port when storing water (for example, see JP-A-6-3183). (See FIG. 2). However, in the aerosol injection apparatus provided with the hemispherical cap mentioned above, it cannot be used for such a washstand and the object of use is limited.

  Then, this invention makes it a subject to provide the adapter for aerosol injection apparatuses, and an aerosol injection apparatus which can inject | pour the contents into various objects, for example, washbasins, a kitchen sink, drain pipes, such as a bathtub.

  The adapter for an aerosol container according to the present invention is made in order to solve the above-described problem, and is attached to an aerosol spray device that sprays contents from a spray port, and at least in a drain pipe of a wash basin having a drain plug. An adapter capable of injecting the contents of an aerosol injection device, wherein the attachment member has one end attached to the aerosol injection device, and is attached to the other end of the attachment member so as to reduce in diameter toward the tip side. A distal end member having an inserted portion, wherein the distal end member has a recess capable of accommodating a drain plug formed in the distal end surface of the insertion portion, and the through hole communicating with the injection port of the aerosol injection device It is formed in the recess.

  According to the above-mentioned adapter for an aerosol spraying device, since it has a tip member having an insertion part formed with a recess capable of accommodating a drain plug, first, when using it for a wash basin having a drain plug, While being accommodated in the recessed part of an insertion part and making the front end surface of an insertion part contact | abut with the drain outlet periphery of a wash basin, it can be sent in into the drain pipe of a wash basin, without leaking outside. In addition, since the insertion portion is formed to reduce in diameter toward the distal end side, the minimum outer diameter of the insertion portion is made smaller than the inner diameter of the drain port of the bathtub, and the maximum outer diameter is made smaller than the inner diameter of the drain port. By enlarging, since the drainage port of the bathtub can be tightly plugged by the insertion part of the tip member, the contents injected from the through hole of the recess can be fed into the drainage pipe without leaking outside. Furthermore, as shown in FIG. 11, the drainage port of the kitchen sink has a water reservoir extending upward from the bottom surface, and this water reservoir is connected to the drainage pipe. Since the outer diameter of the drain plug of the base is smaller, the upper end of the water reservoir can be sealed with the bottom of the recess while the upper portion of the water reservoir is accommodated in the recess of the insertion portion of the tip member. Can be fed into the drain pipe of the sink without leaking outside. In addition, the above-mentioned “drain plug” is located above the drain of the wash basin when not in use, and is installed so that it can be moved up and down so as to lower and seal the drain outlet when storing water in the wash basin. It means a drain plug.

  The aerosol injection adapter can take various configurations. For example, the tip member further includes a tip contact portion that extends upward from the tip outer peripheral edge portion of the insertion portion and extends outward. Preferably it is. Thereby, a tip member can be stuck more and it can control that the contents leak outside.

  Moreover, it is preferable that the tip member further includes a collision wall having a through hole formed in the bottom surface of the recess and formed above the through hole. By providing a collision wall above the through hole in this way, even if it is accidentally ejected toward the face of a person, the contents ejected from the stem ejection port exit the through hole. Then, since it once collides with the collision wall, it can be prevented from being directly sprayed on the human face or the like.

  In addition, the tip member is formed separately from the mounting member so as to be rotatable with respect to the mounting member, and by rotating the tip member with respect to the mounting member, an aerosol spray device is provided to prevent the injection of contents. It is preferable to be able to switch between a lock position for locking and a release position for releasing the lock. Thus, by rotating the tip member to enable switching between the lock position and the release position, it is possible to prevent erroneous contents from being shot.

  In addition, since the insertion part has a truncated cone shape, when the outer wall of the insertion part comes into contact with the drain pipe, the contact surface becomes a straight line. Since it becomes possible, it is preferable to form in a truncated cone shape.

  Moreover, the said recessed part is 12-20 mm in depth, it is preferable that an internal diameter is 30-70 mm, a depth is 15-17 mm, and it is more preferable that an internal diameter is 45-50 mm. Such a size should just be a size which can accommodate the drain plug generally installed in the washstand.

  Moreover, the aerosol injection apparatus which concerns on this invention is equipped with one of the said adapters for aerosol injection apparatuses. Thus, since the aerosol injection apparatus which concerns on this invention is equipped with one of the adapters for said aerosol injection apparatuses, it can wash | clean various drainage pipes.

  Although this aerosol injection apparatus can take various configurations, for example, in a state where the aerosol injection apparatus can inject the contents, the total length is preferably 180 mm or less. A washbasin or the like usually has a tap faucet located above the drain, but when the aerosol spray device is set at the drain by setting the total length of the aerosol spray device to 180 mm or less, the tap The aerosol spray device can be used without interfering with.

  Moreover, it can also be set as the aerosol injection apparatus which injects the content which has a washing | cleaning component so that the inside of a drain pipe may be wash | cleaned.

  As described above, according to the present invention, it is possible to provide an adapter for an aerosol injection device and an aerosol injection device capable of injecting contents into various objects, for example, a sink such as a sink, a kitchen sink, and a bathtub. Can do.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of an aerosol injection device adapter and an aerosol injection device equipped with the same according to the present invention will be described with reference to the drawings. 1 is a perspective view of an aerosol injection device equipped with an adapter for an aerosol injection device, FIG. 2 is a front view of the aerosol injection device equipped with an adapter for an aerosol injection device, and FIG. 3 is a cross-sectional view taken along line AA in FIG. 4 is a side view of the aerosol injection device equipped with the adapter for the aerosol injection device, FIG. 5 is a sectional view taken along line BB in FIG. 4, FIG. 6 is an enlarged view showing the details of the periphery of the through hole, and FIG. It is a top view of the aerosol injection apparatus with which the adapter was mounted | worn. In addition, in FIGS. 1-5, all the adapters for aerosol injection apparatuses are in a locked position.

  As shown in FIGS. 1 to 5, the aerosol injection device 1 includes an aerosol container 2 and a stem 3 extending from the upper end, which is the tip of the aerosol container 2, and an aerosol injection device adapter 4 is mounted on the upper end side.

Although not shown in detail, the aerosol container 2 includes an outer cylinder 21 having an upper end and a lower end opened. The lower end opening of the outer cylinder 21 is closed by a bottom member 22, and the upper end opening Are closed by a mounting cap 23 having a central opening and a top dome 24 for closing the central opening of the mounting cap 23. The lower end edge of the outer cylinder 21 and the outer peripheral edge of the bottom member 22 form a tightening part 221, and the upper end edge of the outer cylinder 21 and the outer peripheral edge of the mounting cap 23 form the tightening part 231. Forming. The aerosol container 2 may be made of any material as long as it can withstand the internal pressure caused by the contents enclosed inside, and is preferably an inner surface coated metal such as tinplate.

  The stem 3 is formed in a cylindrical shape, and an upper end opening thereof is used as an injection port 31. The stem 3 is connected to a valve (not shown) attached to the mounting cap 23 inside the aerosol container 2, and is installed to be movable up and down with respect to the mounting cap 23. As the configurations of the stem 3 and the valve, well-known configurations can be adopted. For example, the valve is opened by pushing the stem 3 into the aerosol container 2, and the injection port 31 of the stem 3 is caused by the internal pressure of the aerosol container 2. On the other hand, when the contents are injected through the stem 3, when the stem 3 is released, the stem 3 moves to the original state by the biasing force of the spring, and the valve can be closed.

  An aerosol injection device adapter 4 is attached to the aerosol injection device 1 configured as described above. The aerosol injection device adapter 4 includes an attachment member 5 and a tip member 6.

  The attachment member 5 has a lower end portion (one end portion) attached to a winding fastening portion 231 on the upper end side of the aerosol container 2. The attachment member 5 is cylindrical, and an annular protrusion 51 is formed at the lower end portion of the inner wall surface thereof. The protrusion 51 is configured to be engaged with the winding portion 231 of the aerosol container 2. ing. An annular protrusion 52 is also formed on the upper end of the inner wall surface of the mounting member 5, and this protrusion 52 engages with a protrusion 611 of a guide portion 61 of the tip member 6 described later, thereby The member 6 is fixed to the aerosol injection device 1 via the attachment member 5. As shown in FIG. 4, the attachment member 5 is formed with a first protrusion 53 and a second protrusion 54 that extend upward from the upper end. Since the first protrusion 53 and the second protrusion 54 have different heights (the first protrusion 53 is higher than the second protrusion 54), a stepped portion 55 is formed at the boundary portion. Has been.

  The tip member 6 is attached to the upper end portion (the other end portion) of the attachment member 5, and is attached to the aerosol injection device 1 via the attachment member 5. The tip member 6 has a cylindrical guide portion 61, a truncated cone-shaped insertion portion 62 whose diameter decreases toward the upper end side, and a diameter that increases upward from the outer peripheral edge of the upper end of the insertion portion 62. And a tip abutting portion 63 extending so as to be.

  The cylindrical guide portion 61 has an outer diameter smaller than the inner diameter of the mounting member 5, and a lower portion thereof is inserted into the mounting member 5. An annular protrusion 611 is partially formed on the lower side of the guide portion 61. The protrusion 611 engages with the protrusion 52 of the attachment member 5 described above, so that the tip member 6 is attached to the attachment member. 5 is prevented from coming out.

  The frustoconical insertion portion 62 is integrally connected to the upper end of the guide portion 61, and the lower end of the insertion portion 62 is formed larger than the outer diameter of the guide portion 61. As a general rule, the size of the insertion portion 62 is such that the drain of the bathtub can be tightly plugged as will be described later, and the outer diameter of the upper end of the insertion portion 62 is smaller than the inner diameter of the bathtub drain. The outer diameter of the lower end of the insertion part 62 is formed larger than the bathtub drain. Specifically, since the drain of the bathtub is large and its inner diameter is about 55 mm, the outer diameter of the lower end of the insertion portion 62 is preferably 25 to 80 mm, and more preferably 50 to 55 mm. In addition, since the drain outlet of the bathtub is formed in various sizes, the outer diameter of the upper end of the insertion portion 62 may be larger than the inner diameter of the drain outlet of the bathtub. In this case, since the drain port of the bathtub cannot be sealed with the insertion portion 62, the tip contact portion 63 described later is brought into contact with the periphery of the drain port and sealed. Further, as shown in FIG. 4, a first protrusion 621 and a second protrusion 622 extend downward from the lower end of the insertion part 62. Since the first projecting portion 621 and the second projecting portion 622 have different lengths extending downward (the second projecting portion 622 is longer than the first projecting portion 621), the boundary portion includes A step portion 623 is formed. The size of the stepped portion 623 is substantially the same as the stepped portion 55 of the mounting member 5 described above.

  A recess 64 is formed in the upper end surface of the insertion portion 62. As will be described later, the recess 64 only needs to be formed to a size that can accommodate the drain plug of the washstand. Specifically, since the drain plug of the washstand is large and has a height of about 15 mm and an outer diameter of about 45 mm, the recess 64 has a depth of 12 to 20 mm and an inner diameter of 30 to 70 mm. Preferably, the depth is 15 to 17 mm, and the inner diameter is more preferably 45 to 50 mm. As shown in detail in FIG. 6, a through hole 66 is formed at the center of the bottom surface 65 of the recess 64. A guide tube 67 extending downward from the periphery of the through hole 66 is formed on the back surface of the bottom surface 65, and the contents injected from the injection port 31 of the stem 3 are passed through the guide tube 67 through the through hole 66. It is comprised so that it may be injected from. Thus, a collision wall 68 is formed above the through-hole 66 in order to prevent the content ejected from the through-hole 66 from being accidentally directly injected onto a human face or the like.

  A tip contact portion 63 is formed to extend upward from the upper end of the insertion portion 62 described above. The distal end abutting portion 63 is composed of an upright portion 631 extending upright from the outer peripheral edge portion of the upper end of the insertion portion 62 and an inclined portion 632 extending upward and outward from the upper end of the upright portion 631. Yes. Since the inclined portion 632 is formed in a thin shape and slightly elastically deforms, the inclined portion 632 is configured to be in close contact with an object to be contacted.

  Next, the usage method of the aerosol injection apparatus 1 comprised as mentioned above is demonstrated, referring drawings. FIG. 8 is a side view of the aerosol injection device with the aerosol injection device adapter released from the locked state of the aerosol injection device, and FIG. 9 is a state in which the aerosol injection device with the aerosol injection adapter attached is used for the washstand. FIG. 10 is an explanatory view showing a state used for a bathtub, and FIG. 12 is an explanatory view showing a state used for a kitchen sink.

  First, when the aerosol injection device 1 is not used, the tip member 6 is rotated clockwise in FIG. 1 and held in the locked position in order to prevent the contents from being accidentally injected (see FIG. 1). 1 to FIG. 5). As clearly shown in FIG. 4, the lock position means that the first and second projecting portions 621 and 622 of the insertion portion 62 face the first and second projecting portions 53 and 54 of the mounting member 5. It is a position. In this way, by setting the insertion portion 62 and the protruding portions of the attachment member 5 to be opposed to each other, the distal end member 6 is held away from the aerosol injection device 1 and does not move even when the distal end member 6 is pushed down. Therefore, the aerosol injection device 1 is locked so that the contents are not injected by the stem 3 being pushed down into the aerosol container 2. Further, a step 623 defined by the first and second protrusions 621 and 622 of the insertion portion 62 and a step 55 defined by the first and second protrusions 53 and 54 of the attachment member 5 are provided. By engaging each other, the tip member 6 is prevented from rotating further clockwise from the lock position.

  Next, a method for injecting contents by releasing the locked state of the aerosol injection device 1 will be described. First, the tip member 6 is rotated counterclockwise in FIG. 1 to the release position as shown in FIG. The release position is a position where the first and second protrusions 621 and 622 of the insertion portion 62 do not face the first and second protrusions 53 and 54 of the attachment member 5. When the tip member 6 is rotated to the release position in this way, the tip member 6 can be pushed down, and by pushing down the tip member 6, the stem 3 can be pushed down by the guide tube 67 and the contents can be ejected. The locked state of the injection device 1 can be released.

  Next, a method for removing dirt from various drainage pipes by injecting the contents of the aerosol injection device 1 with the tip member 6 rotated to the release position as described above will be described.

  First, as shown in FIG. 9, the case where the drain pipe 12 of the wash basin 10 provided with the drain plug 11 is washed will be described. First, the aerosol injection device 1 is turned upside down, the drain plug 11 is accommodated in the recess 64 of the tip member 6, and the tip contact portion 63 is brought into contact with the flat portion 13 that is normally provided around the drain port. In this state, by pushing down the aerosol container 2, the guide cylinder 67 of the tip member 6 presses the stem 3 and the stem 3 is pushed into the aerosol container 2. As a result, the valve (not shown) is opened, and the content containing the cleaning component enclosed inside is injected from the injection port 31 of the stem 3. The contents injected from the injection port 31 of the stem 3 pass through the through-hole 66, once collide with the collision wall 68, change the traveling direction so as to go outward, and advance into the recess 64. Since the tip contact portion 63 is in contact with the flat portion 13, the content that has advanced into the recess 64 proceeds from the recess 64 into the drain pipe 12 without leaking to the outside, and adheres to the inner wall of the drain pipe 12. Can remove dirt.

  Next, as shown in FIG. 10, the case where the drain pipe 21 of the bathtub 20 is washed will be described. First, the aerosol injection device 1 is turned upside down, and the insertion portion 62 of the tip member 6 is inserted into the drain port 22 of the bathtub 20. Then, since the maximum outer diameter of the insertion part 62 is formed larger than the drain port 22 of the general bathtub 20, the state where the drain port 22 of the bathtub 20 is sealed with the insertion part 62 of the tip member 6 Become. By further pushing down the aerosol container 2 from this state, the stem 3 is pushed into the aerosol container 2 as described above, and the contents are ejected from the injection port 31 of the stem 3. Proceeding into the drain pipe 21 through the recess 64, the dirt attached to the inner wall of the drain pipe 21 can be removed. In addition, in the said embodiment, although the drain port 22 of the bathtub 20 is formed larger than the minimum outer diameter of the insertion part 62 of the front-end | tip member 6, the inner diameter of the drain port 22 of the bathtub 20 is the minimum outer diameter of the insertion part 62. In some cases. In this case, the tip contact portion 63 can be sealed by contacting the flat portion 24 around the drain port 22.

  Then, the case where the drain pipe of the kitchen sink is washed will be described. The sink outlet 30 of the sink generally has a structure as shown in FIG. 11, and a cylindrical water tank 31 extends upward from the bottom surface, and water is stretched around the water tank 31. The water seal 32 is disposed so as to cover the upper side of the water reservoir 31. When cleaning the drain pipe 33 of the drain port 30 having such a structure, first, the water seal 32 is taken out, and the aerosol injection device 1 is turned upside down as shown in FIG. The upper end of the water storage cylinder 31 is brought into contact with the bottom surface 65. Then, by pushing down the aerosol container 2, the contents adhered to the inner wall of the drain pipe 33 can be washed by injecting the contents into the drain pipe 33 as described above.

  As mentioned above, according to this embodiment, since the recessed part 64 is formed in the upper end of the insertion part 62 of the adapter 4 for aerosol injection apparatuses, the drain pipe 12 of the washstand 10 in which the drain plug 11 was installed can also be wash | cleaned. In addition, the drain pipe 21 of the bathtub 20 and the drain pipe 33 of the kitchen sink can be washed.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to these, A various change is possible unless it deviates from the meaning of this invention. For example, in the above embodiment, the tip contact portion 63 is composed of the upright portion 631 and the inclined portion 632 formed from the upper end of the insertion portion 62. However, the insertion portion 62 is simplified as shown in FIG. The upper end of the tip can also be used as the tip contact portion 63.

  Further, as shown in FIG. 14, in order to facilitate the rotation of the tip member 6, a grip portion may be formed in the first and second projecting portions 621 and 622 of the insertion portion 62 by a plurality of grooves.

  In the above embodiment, the through hole 66 is formed at the center of the bottom surface 65 of the recess 64. However, the present invention is not particularly limited. For example, the through hole is formed in the side wall of the recess 64 and the injection port of the stem 3 is formed. You may connect so that it may communicate with 31. By doing so, it is possible to prevent the contents from being directly jetted onto a human face or the like by mistake, without forming the collision wall 67.

  In the above embodiment, the collision wall 68 is provided above the through-hole 66, but this can be omitted. In this case, it is preferable to provide a cap or the like in order to prevent the contents from being accidentally ejected.

  Further, in the above embodiment, the aerosol container 2 is filled with the contents composed of the stock solution containing the cleaning component and the propellant composed of liquefied gas or compressed gas, but the contents are particularly limited to this. For example, a sterilizing agent, a deodorizing agent, a fragrance agent, a bleaching agent, or the like can be enclosed in the aerosol container 2 instead of the stock solution containing the cleaning component.

  Moreover, in the said embodiment, although the insertion part 62 of the front-end | tip member 6 is formed in truncated cone shape, the shape of this insertion part 62 should just be formed so that a diameter may become small toward the front end side, For example, as shown in FIG. 15, the side surface of the insertion portion 62 may be curved inward, and conversely, as shown in FIG. 16, the side surface of the insertion portion 62 faces outward. May be curved.
