Description

  The present invention relates to an aerosol device. More specifically, the present invention relates to an aerosol apparatus that can insert a rod-shaped member and perform an injection operation to reliably inject the contents at the tip.

JP 2001-39478 A Japanese Patent Laid-Open No. 2-109894

  Normally, aerosol products are used in two operations: aiming at an injection target and injecting by operating an injection member (push button) with a finger. Such aerosol products are used as spray products for spraying over a wide range such as for space, for hair, and for the human body. On the other hand, there is also known an aerosol product for spraying a narrow range or a small object by narrowing the injection range.

  However, aerosol products with a narrow injection range achieve their purpose by narrowing the injection pattern, so the momentum of the injection to the object becomes too strong, the stimulus to the object becomes strong, and the surroundings by rebounding There are problems such as scattering. Further, the content to be ejected is ejected while aiming at the object. However, since the ejecting member moves as the ejecting member is pushed down, the aim is likely to be misaligned, and it may not be accurately ejected.

  2 or 4 of Patent Document 1 discloses an aerosol device that performs an injection operation with a hand or a sole and injects the contents in an aerosol container onto the hand or the sole that performs the operation. This aerosol device is preferable because it does not need to be jetted with respect to the object. However, even with such an aerosol device, it is difficult to inject only at the tip of the rod-like object.

  Patent Document 2 discloses a beverage container in which the contents can be taken out by inserting the spout shaft into a valve and pushing down the spout. The beverage container of Patent Document 2 is intended to provide a beverage container in which the quality is not deteriorated even if the spout is attached and taken out several times. The beverage container is sealed with a seal packing (reference numeral 6 in FIG. 3 of Patent Document 2) so that the content does not spill out from the spout shaft when the spout is attached, and the spout is removed. The upper end of an axially moving valve seat (stem) (reference numeral 10 in FIG. 3) is pressed against the lower surface of the seal packing by a spring 11 for sealing.

  In the beverage container of Patent Document 2, it is possible to inject the contents onto the tip of the bar-shaped member by inserting the bar-shaped member instead of the spout. However, when a rod-like member is used in the valve structure of Patent Document 2, if the valve seat is pushed down at the tip of the rod-like member, a gap is formed between the upper end of the valve seat and the lower surface of the seal packing, and the contents are Although it is injected to the tip, the size of the gap differs depending on the amount of push-down of the rod-like member, so that the amount of injection (the amount attached to the tip) differs every time it is used, and the usability is poor. Further, when the rod-like member is operated obliquely downward, the valve seat may be inclined after the operation and may not return to the original state, and the sealing performance when not in use may be deteriorated. Further, when the rod-shaped member is pushed down, the tip reaches the side surface of the seal position, so that if dust or dust adheres to the tip, it is sandwiched between the valve seat and the packing and the sealing performance is lowered.

  The present invention can perform a jetting operation using a rod-shaped member that is an injection target, and can reliably spray the contents to the vicinity of the tip of the rod-shaped member. It is a technical problem to provide an aerosol device that does not.

In addition, since the stem of the aerosol valve is a tilting stem, the force required to open the stem can be reduced. For example, it is difficult to apply downward force, such as a rod-like member that is operated by picking the rod part with a finger. Even so, it is easy to open the stem.

  The second aspect of the aerosol device of the present invention is an aerosol for injecting contents to the vicinity of the tip of a rod-shaped member comprising an aerosol container provided with a container body and an aerosol valve fixed to the opening of the container body. The aerosol valve includes a mounting cup that closes an opening of a container body, and a tilting stem, and the mounting cup includes a stem insertion port that inserts a stem at a center thereof, and a stem insertion port. It has a cylindrical side wall formed so that its upper end is located above the upper end of the stem, and the tip of the rod-shaped member can be inserted, and when the rod-shaped member is inserted, An insertion part for supporting the rod-shaped member is constituted by the side wall and the upper end of the stem, and the inside of the insertion part is moved up and down by an aerosol valve. Since the side wall acts as a restricting means for restricting the movement of the stem in the axial direction of the aerosol container, the injection target is similar to the first aspect. By inserting the tip of a certain rod-shaped member into the insertion portion and pushing down the rod-shaped member as it is, the content can be injected only to the tip of the rod-shaped member without scattering the content around.
  Further, since the side wall acts as a restricting means for restricting the movement of the stem in the axial direction of the aerosol container, the stem can be lowered in the axial direction of the aerosol container by performing a push-down operation of the insertion portion with the rod-shaped member. In addition, when the rod-shaped member is removed from the insertion part, the stem that is biased upward by a spring or the like can be raised in the axial direction of the aerosol container and returned to its original position without tilting. High sealing performance can be secured even when used.
  Furthermore, because the stem of the aerosol valve is a tilting stem, the force required to open the stem can be reduced. Even so, it is easy to open the stem.
  The aerosol valve includes a mounting cup that closes the opening of the container body. The mounting cup has a stem insertion port for inserting a stem at the center thereof, rises upward from the stem insertion port, and an upper end of the stem cup. A cylindrical side wall formed so as to be positioned above the upper end, and an insertion portion is formed by the upper end of the side wall and the stem, so that the stem can be directly operated by a rod-shaped member, and the stem is Since the movement of the aerosol container is restricted in the axial direction, high sealing performance can be ensured even after repeated use. Further, such an aerosol device has a small number of parts and is low in cost.

The tilted stem is in communication with the passage in the stem, and the recess acts as a restricting means for restricting movement of the stem in the axial direction of the aerosol container. In the same manner, by inserting the tip of the rod-shaped member that is the injection target into the insertion portion and pushing down the rod-shaped member as it is, the content can be sprayed only to the tip of the rod-shaped member without scattering the content around. it can.
  Further, since the operation member having the bottomed cylindrical insertion portion is mounted on the stem, when the rod-shaped member is inserted into the insertion portion, the rod-shaped member is supported in the axial direction of the aerosol container by the insertion portion.
Therefore, it is easy to push down.
  Further, since the concave portion acts as a restricting means for restricting the movement of the stem in the axial direction of the aerosol container, the stem can be lowered in the axial direction of the aerosol container by performing a push-down operation of the insertion portion with the rod-shaped member. . In addition, when the rod-shaped member is removed from the insertion part, the stem that is biased upward by a spring or the like can be raised in the axial direction of the aerosol container and returned to its original position without tilting. High sealing performance can be secured even when used.
And since the said cover member has a cylindrical recessed part and an operation member is supported by the recessed part and the upper end of a stem, a stem can be operated with a rod-shaped member via an operation member, and the operation connected to the stem Since the movement of the member is restricted in the axial direction of the aerosol container by the concave portion, high sealing performance can be secured even after repeated use.

Next, the aerosol device of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing an embodiment of the aerosol device of the present invention, and FIG. 2 is a partially enlarged cross-sectional view of FIG. 5, 6, 8, and 9 are sectional views showing other embodiments of the aerosol device of the present invention. FIG. 4 is a sectional view showing an embodiment of the third aspect of the aerosol apparatus of the present invention. FIG. 7 is a sectional view showing an embodiment of the second aspect of the aerosol device of the present invention. FIG. 3 shows an embodiment of an aerosol device outside the scope of the present invention.

  An aerosol apparatus 10 shown in FIG. 1 includes a container body 11 having pressure resistance, an aerosol valve 12 fixed to an opening of the container body, an operation member 13 attached to the aerosol valve, and the entire operation member. And a cover member 14 attached to the aerosol container so as to cover the container. A rod-like member (cotton swab) 15 is for operating the aerosol device 10.

The container body 11 is formed by forming a metal plate such as aluminum or tinplate into a bottomed cylindrical shape having a body portion 16 and a bottom portion 17 by drawing or impact processing, and then performing necking or the like on the upper end of the body portion. A shoulder portion 18 is formed, and a bead portion 19 is formed at the upper end of the shoulder portion by curling. The bottom portion 17 is formed in a mountain shape that rises in a tapered shape toward the center. Thereby, the pressure resistance of the container with respect to the internal pressure is increased and is not easily deformed. In addition, you may use the thing of other materials which have pressure | voltage resistance, such as a synthetic resin and pressure | voltage resistant glass.
In addition, the aerosol device 10 is sprayed using a rod-shaped member 15 in a state of being placed on a fixed surface such as a floor surface, and the contents (aerosol composition) are sprayed to the tip 15a of the rod-shaped member that has been operated. It is. Therefore, it is preferable that the container body 11 has a relatively stable bottom diameter with respect to the height, and the ratio of the height to the bottom diameter is 2/1 to 1/3, preferably 1.5 / 1 to 1. /2.5. Moreover, the diameter of the bottom part is 20-150 mm, Preferably it is 30-130 mm.

  As shown in FIG. 2, the aerosol valve 12 includes a mounting cup 21 that is fixed by being crimped to the bead portion 19 of the container body 11, a cylindrical housing 22 that is held at the center of the mounting cup, A stem 24 having a stem hole 23 that is accommodated in a vertically movable manner, a spring 25 that constantly biases the stem upward, a stem rubber 26 that closes the stem hole, and extending from the lower end of the housing to the bottom of the container body. The dip tube 27 is provided.

  The mounting cup 21 covers the opening of the container body, and a curved flange part 28 that is crimped to the bead part 19 of the container body via the gasket 20; a housing holding part 29 that holds the housing 22; and a stem 24 that is inserted in the center. It is a conventionally well-known thing which has the stem insertion port 30 to do. Such a mounting cup 21 is manufactured by processing a metal plate such as aluminum or tinplate.

  The housing 22 has a bottomed cylindrical shape for mounting a communication hole 31 communicating with the inside of the container formed at the bottom, a dip tube engaging portion 32 provided on the outer periphery of the bottom, and a stem rubber. And a step portion 33 formed at the upper end.

  The stem 24 includes a stem hole 23 and an in-stem passage 34 communicating with the stem hole 23. Further, an annular engaging portion 35 protruding in the radial direction is formed at a portion slightly below the stem hole 23 of the stem 24 so that the stem does not protrude from the stem insertion port 30 of the mounting cup. Furthermore, the lower part than the engaging part 35 of the stem is formed so that the diameter, width, and height are smaller than the inner shape of the housing. Since the stem 24 is formed in this manner, the stem 24 can be slightly inclined with respect to the axial direction of the housing as well as moving up and down in the housing. Such a stem 24 is known as a tilting stem. And unlike a normal stem, the external force required in order to open the stem hole 23 may be small. When the aerosol valve is opened by gripping and operating the rod-shaped member with a finger as in the present invention, the stem 24 is difficult to push down, and thus a stem that is relatively easy to open is used. However, a normal stem may be used.

  Returning to FIG. 1, the operation member 13 is a cylindrical member that includes a stem mounting portion 36 that is mounted on the stem of the aerosol valve and an insertion portion 37 that inserts an injection target. The insertion portion 37 is formed in a bottomed cylindrical shape, and when the tip of the rod-shaped member is inserted, the rod-shaped member is supported in the axial direction of the aerosol container and guided so that it can be pushed down the shaft. The inner diameter of the insertion portion can be arbitrarily determined depending on the size of the injection target, but is preferably 10 mm or less, and more preferably 8 mm or less, from the viewpoint that the contents are easily attached uniformly to the tip of the rod-shaped member. Further, the inner diameter of the insertion portion is 1 to 2 times, more preferably 1 to 2 times so that the rod-like member can be easily inserted with respect to the outer diameter of the tip of the rod-like member and the tip of the rod-like member does not come out of the insertion portion. It is preferably 1.5 times. The height of the insertion portion can be arbitrarily determined depending on the size of the injection target, but is 3 to 50 mm, more preferably 5 to 30 mm from the point of easy support in the axial direction of the aerosol container when the rod-shaped member is inserted. It is preferable. The inside of the insertion portion 37 communicates with the stem passage 34 and the injection hole 37a. The diameter of the injection hole 37 a is formed smaller than the distal end portion 15 a of the rod-like member 15. Thereby, it is prevented that the rod-like member 15 is fitted into the injection hole 37a and is difficult to remove or cannot be removed. Note that one or more injection holes 37a may be provided.

The cover member 14 acts as a restricting means for restricting the movement of the operation member 13 in the axial direction of the aerosol container, and the outer cylindrical portion 38 engaged at the lower end of the outer periphery of the bead portion 19 of the container body or the curved flange portion 28 of the mounting cup. And the top surface portion 40 that connects the outer tube portion and the inner tube portion at the upper end thereof. The cover member 14 also acts as a protective member that protects the upper part of the aerosol container. In the present embodiment, the cylindrical portion 39 of the cover member regulates the movement of the stem 24 via the operation member 13.
The housing 22, the stem 24, the operation member 13 and the cover member 14 are each manufactured by injection molding or the like using synthetic resin as a material.

  The aerosol device 10 of the present invention configured as described above is an injection target on the insertion portion 37 of the operation member of the aerosol device mounted on a flat surface such as a washstand, a table, a floor surface, or fixed to a wall or the like. A rod-like member 15 (for example, a cotton swab) is inserted for operation. At that time, the rod-shaped member is supported in the axial direction of the aerosol container by the bottomed cylindrical insertion portion 37. By pushing down the rod-shaped member 15 in this state, the force is transmitted to the stem 24 via the operation member 13. That is, by inserting the rod-shaped member 15 and pushing it down as it is, the operation member 13 moves below the axis of the aerosol container while being guided by the inner cylinder portion 39 of the cover member 14, and accordingly, the stem 24 also moves below the axis. Thus, the stem hole 23 is opened. At this time, the contents (aerosol composition) in the container main body are sprayed from the dip tube 27 to the tip of the rod-shaped member from the spray hole 37a of the operation member through the inside of the housing, the stem hole, and the passage in the stem. Thereafter, when the rod-shaped member is pulled out from the insertion portion, the operating member moves upward in the shaft while being guided by the cylindrical portion 39, and accordingly, the stem also moves upward in the shaft and the stem hole 23 is closed. As a result, the contents can be attached to the tip of the rod-shaped member, and this can be applied to the target location. In this embodiment, a tilting stem is used to open the stem hole 23 with a small force. However, the stem can be moved up and down only in the axial direction of the aerosol container by the regulating means (inner cylinder portion 39). When the rod-shaped member is pulled out, the stem is restored to the original position without being tilted, so that a high sealing performance can be maintained even after repeated use. Further, the stem hole is opened by pushing down the rod-shaped member, and the injection amount per unit time (g / sec) is controlled by the cross-sectional area of the stem hole. The injection amount is constant, the variation in the amount adhering to each use is small, and it is easy to use.

  The aerosol device of the present invention can be used for various applications. Examples of the contents include a wiping agent that cleans the inside of the ear, an adhesive for attaching and removing earwax, a refreshing agent that cleans the space between the teeth (in the oral cavity), and sterilizing and disinfecting wounds such as stabs and cuts. Antiseptics to stop itching from agents, hemostats, insect bites, antifungal agents to kill athlete's foot, cleansing agents to remove makeup locally, nail enamel removers to remove nail polish, erase stains, etc. Foundations that make up locally, skin care such as stretching wrinkles in the eyes, mascara that thickens eyelashes, eye shadows and other human body items, adhesives that remove dust, dust, pests (dead bodies), cleaners, Household goods such as vermilion are listed. However, the aerosol apparatus of the present invention can be used as long as it is used by spraying a liquid or powder on the tip of a rod-shaped member such as a cotton swab or toothpick, and is not particularly limited. Examples of the rod-shaped member include cotton swabs, toothpicks, brushes for teeth and interdental teeth, mascara, and the like, and are not particularly limited.

  The aerosol device 41 shown in FIG. 3 uses a normal stem that can move only in the vertical direction, and does not include a cover member that is a means for restricting movement of the stem. The stem 42 has a cylindrical shape below the stem hole 23 and is formed so that its outer diameter is slightly smaller than the diameter of the inner peripheral surface of the housing. As a result, the stem 42 cannot be tilted, but is configured to be movable up and down in the housing 22. By using a normal stem in this way, the stem itself moves only in the vertical direction, so that it is not necessary to provide a cover member as shown in FIG. However, a cover member may be provided as a protective member. The tilting stem 24 used in the aerosol device 10 of FIG. 1 may be used instead of the normal stem 42. In this case, after inserting the rod-shaped member into the insertion portion 37 of the operation member, the tip of the rod-shaped member is moved. By tilting the rod-shaped member as an axis, the contents can be ejected to the tip of the rod-shaped member, and the operating force becomes very light. Further, in this embodiment, the discharge hole 43 is provided at the bottom of the insertion portion, and the discharge hole 43 can discharge the contents accumulated at the bottom of the insertion portion after injection to clean the inside of the insertion portion. Can be kept in.

  The aerosol device 45 shown in FIG. 4 includes a cover member 46 attached to the outer periphery of the housing holding portion 29 of the mounting cup 21, and includes an attachment portion 47 and a cylindrical portion 48 that regulates the moving direction of the operation member 13. It will be. In this embodiment, when the rod-like member 15 is pushed down by inserting the tip 15 a of the rod-like member into the insertion portion 37 of the operation member, the operation member is moved in the direction of movement by the tube portion 48 of the cover member 46. Is restricted, the aerosol container can be moved only in the axial direction, and the stem can be moved only in the axial direction accordingly. Other configurations are substantially the same as the aerosol device 10 of FIG. Note that. In this embodiment, a brush having a large number of bristles provided at the tip is used as the rod-shaped member.

  The aerosol device 50 shown in FIG. 5 has an inner cylinder portion 52 (concave portion) provided at the center of the cover member 51 directly engaged with the stem 53 of the aerosol valve. The operation member 13 of the aerosol apparatus 10 is also used. That is, the rod-shaped member is inserted into the insertion portion formed by the upper end of the stem 53 and the inner cylindrical portion 52 of the cover member. Further, the rod-shaped member is supported in the axial direction of the aerosol container by the insertion portion, and a downward force can be directly transmitted to the stem to the rod-shaped member. At this time, the movement of the stem is restricted by the inner cylindrical portion 52 and moves up and down along the side surface of the cylindrical portion 52. Therefore, even if the stem is used repeatedly, the stem can return to its original position and maintain high sealing performance. The upper portion of the inner cylindrical portion 52 is a guide portion 54 that is tapered toward the upper end opening 55 in order to facilitate insertion of a rod-like member such as a cotton swab. The other structure is substantially the same as the aerosol device 10 of FIG. 1, and the operation is also the same.

The aerosol device 56 shown in FIG. 6 is for injecting the contents onto the rod-shaped member 15 having a sharp tip like a toothpick, and the inner cylinder portion 52 provided at the center of the cover member 51 is attached to the tip of the rod-shaped member. An insertion assisting member 57 formed in accordance with the outer shape is inserted.
By inserting the insertion assisting member 57 into the inner cylinder portion 52 in this manner, the rod-like member does not enter the stem passage and block the content injection passage. The other structure is substantially the same as the aerosol device 50 of FIG. Since the insertion assisting member 57 is slidable with the inner cylindrical portion 52 and can transmit a downward force applied to the rod-like member to the stem, it can be considered as a kind of operation member attached to the stem. .

In the aerosol device 60 shown in FIG. 7, the peripheral edge of the stem insertion port 30 at the center of the mounting cup rises upward to form a cylindrical portion 61 (side wall). Further, the stem 62 inserted into the stem insertion port 30 is configured such that the upper end thereof is lower than the upper end of the cylindrical portion 61 and is accommodated in the cylindrical portion 61. Similarly to the aerosol device 50 of FIG. 5, this device also serves as an operation member at the upper portion of the stem 62. An insertion portion is formed by the upper end of the stem 62 and the cylindrical portion 61 of the mounting cup. For this reason, when the rod-shaped member is inserted into the insertion portion, the rod-shaped member is supported in the axial direction of the aerosol container by the insertion portion. Further, the downward force applied to the rod-shaped member can be directly transmitted to the stem. The movement of the stem is restricted by the cylindrical portion 61, and the stem moves along the side surface of the cylindrical portion 61 below the axis of the aerosol container. The hole is opened. Also in this embodiment, when the rod-like member is pulled out, the stem moves upward along the cylindrical portion 61 to close the stem hole, and returns to the original position, so that high sealing performance can be maintained.
Depending on the shape of the rod-shaped member, the rod-shaped member may be supported by the step portion 62a of the passage in the stem. Further, the rod-shaped member may be supported so that the passage in the stem is narrowed to a tapered side surface that is narrowed downward. As described above, in the aerosol device of the present invention, as long as the rod-shaped member does not block the content passage, a part of the rod-shaped member may be inserted into the passage in the stem.

  The aerosol device 65 of FIG. 8 is substantially the same as the aerosol device 50 of FIG. 5 except that the cover member 66 is engaged with the outer periphery of the housing holding portion of the mounting cup and the upper end of the stem is shortened. Is. In this case, the inner cylinder portion 39 of the cover member 66 and the upper end of the stem act as an insertion portion, and the inner cylinder portion 39 of the cover member 66 acts as a stem movement restricting means. Therefore, the content in the aerosol container is sprayed to the tip of the rod-shaped member by inserting the rod-shaped member into the inner cylinder portion from the top surface of the cover member and further pushing down.

  The aerosol device 70 shown in FIG. 9 is provided with an operation unit 71 on the side surface of the operation member 13 of FIG. By providing the operation portion 71 in this manner, the rod-shaped member 15 can be inserted into the insertion portion 37, and then the operation portion 71 can be pushed down to inject the contents onto the tip 15a of the rod-shaped member. In addition, the injection operation can also be performed with a rod-like member as in the previous embodiments. In this embodiment, not only the contents are injected at the tip of the rod-shaped member, but also the operation unit 71 is operated without inserting the rod-shaped member to inject the contents onto a wide injection object such as a space or a human body. You can also.
