Abstract

A head cap for an aerosol sprayer, including a cap body (2) and a movable body (3) for jetting operation. The cap body (2) is installed on the upper part of a container (1) for receiving contents. The movable body (3) for jetting operation is provided inside the cap body and has a flow path and a push button (27). The flow path is led from a stem fitting section, which is fitted to a stem of the container, to a jetting opening. When pushed down to a jetting position, the push button (27) causes the contents of the container to be jetted from the jetting opening through the flow path. Side face sections (6) of the cap body are adapted to be elastically deformable. When the push button section (27) of the movable body (3) for jetting operation is pushed down to be in the jetting position, the side face sections (6) of the cap body are pressed inward to make the movable body (3) engaged by the side faces (6), thereby the movable body is held at the jetting position.

Description

TOP COVER FOR AEROSOL TYPE ATOMIZER TECHNICAL FIELD The present invention relates to an upper lid for an aerosol-type atomizer, and more particularly, as an upper lid for an aerosol-type atomizer in which when all the contents in an aerosol-type atomizer container are sprayed and used (when the use of the spray type atomizer is finished), a residual gas that remains in the container can be discharged.

BACKGROUND TECHNIQUE An aerosol-type atomizer is constituted by a container that accommodates its content as a chemical inside, and a top cover mounted on top of the container. The container which accommodates its contents as a chemical and gas inside it in a sealed state is provided at its upper end part as a rod, which is deflected upwards, can be pushed down and is structured so that when the rod is pushed down, the contents of the container can be discharged through it. On the other hand, the upper cover, which is mounted on the upper part of the container is made of tur a lid body mounted on the top of the container, and a movable member for the spray operation which is positioned within the body of the lid and which can be rotated and oscillated vertically relative to the body of the lid. The movable member for the spraying operation is provided with a part that fits the stem to fit the stem and with a spray orifice, has a fluid channel extending from the part and fits the stem toward the orifice. sprayed and is provided with a push or push button. The spray-type atomizer thus constituted, this is designed so that the downward thrust of the movable member for the spray operation takes a spray position which causes the contents of the container under pressure of the gas accommodated in the container to be sprayed externally from the orifice. of sprayed via the fluid channel in the mobile member for the spray operation. In that aerosol-type atomizer, when all the contents of the container are sprayed and used (when the use of the spray-type atomizer has finished), there is often the case that gas remains in the aerosol-type atomizer container. For this reason, when the spray-type atomizer is discharged and discarded there is the fear of an accident that an explosion may occur due to the gas remaining in the container, the residual gas. Then, to get rid of an explosion accident due to the residual gas in an aerosol-type atomizer, it has been known, as described in JP U S55-73700 and JP U H04-124918, how to provide the aerosol-type atomizer with a needle or a drilling tool to pierce its container, so that when the use of the spray-type atomizer is completed a hole is drilled in the container with needle or drilling tool to discharge the residual gas into the container therethrough, thereby avoiding the Explosion accident due to residual gas. Also, as described in JP U H01-61082, it has been known how to provide a mechanism, so that when the mobile member of the spray operation moves largely downward in the upper layer, the mobile member for the Spraying operation is coupled with the body of the cap to fix the movable member for the spray operation in a lower position (in a spray state) so that at a normal spray time the contents of the container are sprayed from the the spray bore slightly lowering the movable member for the spray operation, but once the use of the spray-type atomizer is completed, the movable member for the spray operation is moved very much downward by pushing this intensely to fix this on the lower position (in the sprayed state), thereby allowing the waste gas to the container to be completely discharged. In the first type of conventional aerosol spray type, the need to provide the separate atomizer with the needle or drilling tool to perforate the container gives rise to the problem of increasing the number of parts and components to form the aerosol type atomizer. In addition, the need for its use to remove the needle or drilling tool from the aerosol-type atomizer then to perforate the container with this has the problem that its operation is very problematic, since a perforation of the container can cause the residual gas in the container fly out, representing the problem that the operation can be attempted with danger. On the other hand, the latter can greatly alleviate the problems of the operation becoming problematic and becoming dangerous as the first since the residual gas in the container is discharged by moving the movable member for the operation of spraying on the top cover largely down to set this one in the lowest position (in the sprayed state), but since the mobile member for the spray operation can be automatically fixed in the lower position (brought to the spray state) by pushing it intensely, there is a risk that the Problem that a false operation pushes the mobile member for the operation of spraying intensely but only an inadvertence in a normal spray time can cause the mobile member for the spraying operation to be set automatically with the result that the content of the container is sprayed together. An object of the present invention is to provide an upper lid for an aerosol-type atomizer in which the aforementioned problems are overcome, especially in which a residual gas remaining in the container after the use of the spray-type atomizer ends is discharged in a manner easy and safe, and which is also structured so that the aerosol spray can not be operated in a false way while it is being used.

DESCRIPTION OF THE INVENTION A top cover for an aerosol spray is provided in accordance with the present invention, comprising a lid body mounted on the top cover of a container accommodating its contents, and a movable member for the spray operation placed within the body of the cap and having a fluid channel extending from a part that fits the rod to fit with a rod and lead to a spray orifice, the moving member having mu. i i-; for the operation of spraying a pusher push button so that the push down of the push push button takes a spray position that sprayed the contents of the container from the spray hole via the fluid channel, characterized in that the body of the The lid has an elastically deformable side face, so that when the push or push button of the movable member for the spray operation is pushed downwards it takes the spray position, pressing the side face of the lid body inwards to block the movable member for the spray operation with the side face to hold the movable member for the spray operation in the spray position. An upper lid for an aerosol-type atomizer is provided according to the present invention as in the aforementioned aspect, characterized in that the body of the lid has lateral faces and their right and left sides elastically deformable, so that when the push button of thrust of the movable member for the spray operation to be pushed down to the spray position, pressing the side faces on the right and left sides inwardly as a restraint to lock the movable member for the spray operation with the side faces in the right and left sides. According to the present invention, to effect the operation of discharging the waste gas when the use of a spray atomizer has finished, when a user push down the impulse button with the fingers to take a spray position, the user can perform a simple and uncomplicated extreme operation of pressing a side face of the body of the cap to attach the side face with the movable member for the spraying operation and therefore locking the movable member for the side-face spraying operation and can therefore effect the operation easily and safely. Also, according to the present invention, since the content of the container is prevented from being sprayed unless the user performs a particular operation of holding the movable member for the spray operation in the spray position by pressing the side face of the body from the cover to the locking of the movable member for the spray operation with the side face, the problem of falsely spraying the contents into the container when an aerosol spray is used, mainly at the time of normal spray, can be prevented.

BEST MODES FOR CARRYING OUT THE INVENTION An explanation is given with respect to a top cap embodiment for an aerosol-type atomizer according to the present invention. As shown in Figures 1 to 5, the upper cover for this aerosol atomizer basically consists of a cover body 2 mounted on the upper part of a container 1 that accommodates its contents, as a chemical inside, and a movable member for its spray operation 3, which is placed inside the body of the lid 2, which is connected to a part of the body of the lid 2 and which can be rotated and oscillated vertically in relation to the body of the lid 2. The body of the lid 2 comprises a front part 5 which is largely open longitudinally, the side faces 6 on its right and left sides which are flat for most of the parts, a part rear 7 that opens on its upper side, and an upper face 8 that opens on its rear side, the opening of the rear part 7 being continuous with that of the upper face 8. Each of the side faces 6 of the sides right and left is constituted by an outer wall plate 11 and an inner wall plate 12, which are formed to fall on the rear portion of the side face 6 from its upper side to a given height from which the plate of the inner wall 12 is structure to open on its underside. Also, the front part 5, the side faces 6 on the right and left sides and the rear part 7 are provided in their interiors with a cylindrical part 13 whose rear side is cut to have a horizontal cross section almost in the shape of a C and whose The lower end is fitted to the upper part of the container 1. Also, the cylindrical part 13 is formed by a plurality of cuts with vertical indentations 14 extending from its lower end to facilitate its attachment and detachment of the container 1. The front part 5 of the body of the lid 2 is also provided in its lower section with a pair of right lateral retaining parts and left 17 to hold a rotating guide 15 and a nozzle 16 (to be described later) between them from the right and left sides. On the other hand, the movable member for the spray operation 3 has its front end connected to the front part 5 of the body of the lid 2 via a connection 21 that becomes thin inside the front part 5, so that it can rotate vertically after the connection 21 in relation to the body of the cover 2. The movable member for the spray operation 3 is provided in the center at its lower end with a part that fits the rod 23 to fit a rod 22 of the container 1 and in its upper front section with a spray orifice 24. And, it is formed internally with a fluid channel 25 extending from the adjusting part of the rod 23 to the spray orifice 24. Also, the movable member for the spray operation 3. is structured to be higher in its front section and lower in its rear section, and is provided in the lower section with a push or push button 27 which has a cavity 26. Although the mobile body for the spray operation 3 and the body of the cover 2 are shown structured to be integrally connected to each other via the connection 21, this is not a limitation. The movable body for the spray operation 3 and the body of the cover 2 can be separate bodies that can be structured to be connected together by a bolt or the like. However, the movable member for the spray operation 3 and the lid body 2 integrally would be easy in the structural fabrication and, especially if they are made of, for example a synthetic resin material, they can be formed in a single step with a mold and can be manufactured extremely economically. In addition, the front part 5 of the body of the lid 2 is provided in its upper section with the rotating guide 15 in the form of a thin cylinder, which rotates vertically and can be locked in a position that extends virtually horizontally and in a position that extends down. And, the nozzle 16 which is flexible is inserted into the rotating guide 15, and has a rear end fitted with the spray orifice 24 of the movable member for the spray operation 3. In the top cover when used for an aerosol-type atomizer by mounting this on top of the container 1, the first rotary guide 15 with the nozzle 16 is rotated upwards to place them so that they extend virtually horizontally. And, pushing the push button 27 down with the finger in the rear section of the movable body for the spray operation 3 will cause the movable member for the spray operation 3 to descend to take its dew position and therefore the part that fits the rod 23 so that it presses down the rod 22. This will cause the contents of the container 1 to be discharged through the rod 22 under the pressure of a gas in it and then through the fluid channel 25 in the moving body for the spray operation 3 and the spray orifice 24 and through the nozzle 16 fitted to the spray orifice 24 and sprayed forward and externally from the end of the nozzle 16. Also, if the spray-type atomizer is to be stored after stopping the spray of the contents, as shown in Figure 6, the rotary guide 15 with the nozzle 16 is rotated downwards to extend downwards, and is maintained between the retaining pieces 17 provided with ions in the lower section of the front part 5. And, in this upper cover for the spray type atomizer, the side faces 6 on the right and left sides of the body of the cover 2 become elastically deformable. As means for rendering them elastically deformable, it is conceivable to use soft material, for example, 13 lÜM.i i a soft synthetic resin material or make them thinner in their thickness. However, from the point of view of aesthetic considerations, it is optimal if the top cap 2 is made of synthetic resin material, and is better integrally formed with the movable body for the spray operation 3 from the manufacturing aspect. Although it is necessary that the lateral faces 6 on the right and left sides of the body of the lid 2 become elastically deformable, the front part 5, the rear part 7 and the top face 8 as well as the other body parts of the body are required. the cover 2 or the mobile member for the spray operation 3 have some degree of hardness. Accordingly, in practice, use is made of a synthetic resin material having some degree of elastic hardness and deformability to make the body of the lid 2 and the movable member for the dew operation 3 integrally formed in the upper lid opening to a great extent at the same time the rear section of the upper face 8 continuously to the upper side of the upper part 7 to make the side faces 6 on the right and left sides easily elastically deformable. It should be noted here that the previous structure is not a limitation; although at some added cost, the side faces 6 on the right and left sides may be separated from the other parts and may be made of a material that is softer.

On the other hand, the push button 27 for the movable member for the spray operation 3 is provided on its right and left sides with upwardly projecting projections 31, respectively, which were made engageable with the plates of the inner wall. 2 on the side faces 6 of the body of the lid 2, respectively. And, in that structure, when the push button 27 of the movable member for the spray operation 3 is pushed down as shown in Figure 7 to take its spray position, the side faces 6 on the right and left sides of the The body of the lid 2 that are elastically deformable are pressed inwardly as a fastener as shown in Figure 8 to engage the projections 31 provided on the push button 27 of the movable member for the spray operation 3 with the plates of the inner wall 12 of said right and left side faces 6, respectively, for thereby blocking the push button 27 of the movable member for the spray operation 3 with the plates of the inner wall 12 of the right and left side faces 6 and then holding the movable member for the spray operation 3, so that the latter while in the spray position can not rotate upwards as shown in Figures 9 and 10. In this top cover for the spray type atomizer, when the spray type atomizer is used, ie at the time of normal spray, the user while placing the rotary guide 15 with the nozzle 16 so that they extend virtually horizontally can push down the push button 27 of the mobile member for the operation 3 for the thumb to cause the movable member for the spray operation 3 to take its spray position and to spray the contents accommodated in the container 1 from the nozzle 16 placed in the spray orifice 24 of the movable member for the operation 3. On the other hand, when the use of the spray-type atomizer ends, that is when the contents of the container 1 of the spray-type atomizer is sprayed and used, the user while pushing down the push button 27 of the movable member for the dew operation 3 with a finger to cause the movable member for the dew operation 3 to take its dew position can press the side faces 6 on the sides right and left of the body cap 2 inwards as a finger grip. And, in the projections 31 of the push or push button 27 it engages with the plates of the inner wall 12 of the right and left side faces 6 pressed inwardly to lock the movable member for the dew operation 3 with the plates of the inner wall 12 of the right and left side faces 6 and to then hold the movable member for the dew operation 3 in its dew position. This causes the movable member for the spray operation 3 to be left in the dew state and then causes the gas that is retained in the container 1, ie the waste gas, to be completely discharged. In the upper head for the aerosol-type atomizer of that construction, when the use of the aerosol-type atomizer ends, the movable member for the spray operation 3 is blocked with the right and left side faces 6 pressed inward and maintained in the position of dew so that the residual gas in the container 1 can be completely discharged. Further, the operation for the discharge of the waste gas is an extremely simple and uncomplicated operation which requires the user to only push down a push button 27 with a finger to take the spray position and then press the side faces 6 into the right and left sides of the body of the cover 2 inwards in a manner of holding with the fingers to couple the projections 31 of the push button 27 with the plates of the inner wall 12 of the right and left side faces 6 and then lock the member mobile for the spray operation 3, and consequently the discharge of the waste gas can be carried out easily and safely. Also, with the blocking of the mobile member for the 17 ?? GT dew operation 3, since the projections 31 of the push button 27 are engaged with the plates of the inner wall 12 and in effect are locked on the right and left sides, the movable member for the dew operation 3 can not be unlocked with ease, thus allowing residual gas to be completely discharged at the end. Further, with the block of the movable member for the spray operation 3, since the plates of the inner wall 12 of the side faces 6 of the body of the lid 2 are used to lock the mobile body for the spray 3 with this, not there is a need to provide a particular blocking member whose purpose is to block the movable member for the spray operation 3. In this way, limiting the increase of the components to reduce the number of parts, and to simplify the structure, of the cover superior for the spray type atomizer, it is possible to manufacture the top cover economically and even easily. Also, when the spray type atomizer is used, ie at the time of normal dew, the push or push button 27 can simply be pushed down with a finger to spray the contents accommodated in the container 1. On the other hand, when the residual gas is going to be discharged, a particular operation is performed to push down the push button 27 of the movable member for the 18 spray operation 3 to take up the spray position and then press the side faces on the right and left sides of the lid body 2 inwardly so as to hold the fingers to engage the projections 31 of the push button 27 with the plates of the inner wall 12 of the right and left side faces 6. For this reason, unless that particular operation of pressing the side faces 6 on the right and left sides of the body of the cover 2 inwardly so as to hold the fingers for coupling the projections 31 of the push button 27 with the plates of the inner wall 12 of the right and left side faces 6 and therefore to hold the movable member for the dew operation 3 to be effected, there is no moment in that the content inside the container 1 is sprayed. Accordingly, the problem is eliminated that when the spray-type atomizer is in use, ie at the time of normal spray, the contents of the container 1 are sprayed in a false manner. It may be possible to press inward the rear part 7 of the body of the lid 12, instead of the side faces 6 of the body of the lid 2, to lock the movable member for the spray operation 3 therebetween. However, if the rear part 7 of the body of the lid 2 is used, since at the time of normal dew, the user to spray keeps a finger or fingers of the back against the push button 27 of the movable member for the dew operation 3, there arises the problem that at some point the finger or fingers may then push the back part 7 inward to block the movable member for the dew operation 3 on the part 7, so that the contents inside the container 1 can be sprayed. That problem of the contents inside the container 1 being sprayed by a false operation at a normal spray time no longer arises when the side faces 6 on the right and left sides of the cover body 2 are used to block the mobile member of the container. the spray operation 3 according to the present invention. An explanation is given below with respect to an alternative embodiment of the top cap for the aerosol type atomizer according to the present invention. The alternative embodiment is basically identical to the aforementioned embodiment except that the manner in which the movable member for the dew operation 3 engages with the side faces 6 of the lid body is a bit different. This is illustrated in Figure 11 in which the plates of the inner wall 12 are each shown in the form of a tongue that falls virtually in the center of the front and back, of the upper end of each of the side faces 6 On the other hand, the mobile member for Spray operation 3 as shown in Figure 2 is provided at its highest section in elevation where it projects to the right and forward at the rear end with a pair of projections projecting forward 31, respectively. The straight and forward projections 31 were made engageable with the tongue formed within the plates of the wall 2 on the side faces 6 of the body of the lid 2, respectively. Accordingly, when the push button 27 of the movable member for the spray operation 13 is pushed down to take the spray position, the side faces 6 on the right and left sides of the cap body 2 that are elastically deformable can to be pressed inwardly as a finger grip to engage, as shown in Figure 13, the projections 31 provided in the movable member for the spray operation 3 with the plates of the inner wall 12 on the side faces 6 in the left sides, respectively, to thereby block the movable member for the spray operation 3 with the plates of the inner wall 12 on the side faces 6 on the right and left sides and to then clamp the movable member for the operation of spray 3 in the spray position while preventing them from rotating vertically. This does, as in the aforementioned embodiment, that the mobile body for the spray operation twenty-one mrp: 3 when the use of the spray-type atomizer is completed, it is blocked with the side faces 6 on the right and left sides pressed in and it is kept in the dew position and then the waste gas in the container 1 is completely discharged. It should be noted here that the top cap for the aerosol-type atomizer according to the present invention is not considered limited only to what has been shown and described. For example, the coupling of the movable member for the spray operation 3 with the plates of the inner wall 2 on the side faces 6 of the body of the cap 2 is not limited to the described modes and can be done in other places. Further, although the coupling is shown to be made on both right and left sides, the coupling can be made only on one of the right and left sides if the coupling is safe to hold the movable member for the spray operation in the spray position. Also, although the side faces 6 of the body of the lid 2 are shown and described as comprising external wall plates 11 and the plates of the inner wall 12, they may comprise the outer wall plates 11 only, which may be formed with couplings in the form of holes or hooks with which the projections 31 provided in the movable member for the spray operation 3 can be coupled.

In addition, the body of the lid 2 and the movable member for the spray operation 3 are not limited to the structures shown and described. For example, although the movable member for the spray operation 3 is shown and described as having a rotating guide 15 that rotates vertically at the front 5 and the nozzle 16 fits the spray orifice 24 for vertical rotation with the guide Rotary 15, may be without that rotary guide 15 and nozzle 16 and may be of the type with the spray orifice 24 for direct spray as shown in Figure 14.
