Description

  The present invention relates to a container with an application body that contains a content liquid such as a liquid drug, dispenses the contained content liquid, and applies it to a target location.

  2. Description of the Related Art Conventionally, some liquid medicines such as an anti-itch agent and an anti-inflammatory analgesic are contained in a container with an application body to which an application body to be applied to the skin is attached. Such a container with an application body is provided with a valve mechanism so that liquid does not sag when the container is simply inverted, and liquid can be discharged only when the container is applied. The following are proposed as such a container with an application body.

  For example, the coating plug disclosed in Patent Document 1 includes a container main body that stores a coating liquid, a coating plug main body that is tightly assembled to a mouth tube portion of the container main body, and a vertical movement and rotation with respect to the coating plug main body. A crested cylindrical applicator that is displaceable and cannot be pulled out, and a spring interposed between the applicator plug body and the applicator are provided. The coating stopper main body has a ring plate-like substrate positioned on the mouth tube portion of the container main body, and a guide tube that is integrally formed on the inner peripheral end of the ring plate-like substrate and has a seal cylinder on the upper side and a hanging body on the lower side. Is provided. The applicator includes an inner cylinder that is in close sliding contact with the tip of the seal cylinder, a central shaft provided at the center of the inner cylinder, and an inner cylinder between the inner cylinder and the central shaft. Discharge holes that are provided and penetrate the application body are provided. A piston that closely contacts the inner surface of the guide cylinder and has a gap on the inner surface of the pituitary body is attached to the central shaft portion. In the application plug, when the application body is raised, the piston is brought into close contact with the guide cylinder and the content liquid is sealed in the container body. When the application body is lowered, a gap is formed by facing the pituitary body, and the content liquid is discharged from the discharge hole through this gap. Further, since the discharge hole is surrounded by the inner cylinder and the inner cylinder is sealed by the seal cylinder portion, liquid leakage and dripping around the content liquid are prevented.

  A columnar protrusion 42 that is inserted through the insertion hole 28 of the inner plug member 18 is provided on the inner side surface 40 b of the coating plate 40 on the inner plug member 18 side. The protrusion 42 has a thickness that is inserted through the inner peripheral surface of the insertion wall 30 of the inner plug member 18 with a gap, and is provided slightly longer than the insertion direction length of the insertion wall 30 of the inner plug member 18. When the body 38 is attached to the inner plug member 18 and the protrusion 42 is inserted through the insertion wall 30 from above, the tip of the protrusion 42 protrudes from the lower end of the insertion wall 30. At the tip of the protrusion 42 protruding from the lower end portion of the insertion wall 30, an arcuate bulge is provided around the side peripheral surface of the protrusion 42, and a liquid stop valve 44 is provided. The liquid stop valve 44 is in liquid-tight contact with the valve seat portion 32 of the inner plug member 18. A guide portion 46 having a slightly larger diameter than the other portions is formed on the base end portion of the side peripheral surface of the protrusion 42 close to the inner surface 40b of the application plate 40. The guide portion 46 is formed on the extended portion 31 of the insertion wall 30. The thickness is such that the inner surface is fitted with a slight gap.

  The application plate 40 is provided with three pouring holes 48 at equal intervals around the protrusion 42. The pouring hole 48 penetrates the coating plate 40 up and down, and a part of each pouring hole 48 on the center side is applied to the side peripheral surface of the protrusion 42, and the side peripheral surface is notched to each pouring hole 48.

  An elastic body 56 is integrally provided on the end surface 54 a at the tip of the second convex portion 54. As shown in FIG. 4, the elastic body 56 is an elongated plate body having the same width as that of the second convex portion 54 in the diameter direction, and passes through a block-like standing portion 58 that rises from the end surface 54 a with a certain thickness. The elastic body 56 is provided integrally and protrudes along the circumferential direction of the end face 54a from the one side edge of the rising portion 58 in the circumferential direction, and has a predetermined length. The elastic body 56 is curved so as to move away from the end face 54a toward the distal end portion 56a opposite to the upright portion 58. The thickness of the elastic body 56 is smaller than the thickness of the upright portion 58, and when the elastic body 56 is pushed by another member and the curve extends to become a straight line, it is easily elastically deformed without coming into contact with the end face 54a. Four elastic bodies 56 are provided, are provided at equal intervals along the circumference of the end face 54a, and protrude from the upright portions 58 in the same direction along the circumference. The elastic body 56 is, for example, 1.2 to 2.5 times as high as the moving distance of the application body 38 in the ascending / descending direction.

  A cap 60 that covers the inner plug member 18 and the application body 38 is screwed into the male screw 16 and attached to the spout 14 of the container body 12. The cap 60 is provided with a top surface portion 62 positioned outside the application body 38, and the top surface portion 62 is a circle formed by a curved curved surface that is overlapped by opening a predetermined space outside the application plate 40 of the application body 38. It is a board. A cylindrical side surface portion 64 that covers the spout 14 of the container body 12 is formed integrally with the peripheral portion of the top surface portion 62. A shallow groove 65 formed in the vertical direction is provided around the outer peripheral surface of the side surface portion 64 so as to be easily rotated when the cap 60 is opened and closed. A female screw 66 that is screwed into the male screw 16 of the container body 12 is integrally formed on the inner peripheral surface of the side surface portion 64. On the inner surface 62b of the top surface portion 62 on the side of the inner plug member 18, an inner plug member convex portion 68 that contacts the upper surface 24a of the side surface portion 24 of the inner plug member 18 is provided.

  Next, a method for assembling the container with application body 10 of this embodiment will be described. First, when the protrusion 42 of the application body 38 is inserted into the insertion hole 28 of the inner plug member 18 from the upper surface portion 26 side, that is, from above to the vicinity of the lower end portion of the extension portion 31 of the insertion wall 30, The valve 44 comes into contact with the upper surface of the narrowly formed portion of the upper portion of the valve seat portion 32 to be in a temporarily placed state (preset) shown in FIG. Next, the application body 38 is further pushed into the inner plug member 18 side with a strong force of a certain level or more. Since the liquid stop valve 44 of the protrusion 42 is larger than the inner diameter of the valve seat portion 32, the liquid stop valve 44 cannot contact and pass through, but when pressed with a strong force, the liquid stop valve 44 is elastically deformed and becomes smaller and the valve seat portion 32 is elastic The liquid stop valve 44 passes through the valve seat portion 32 and protrudes from the lower end portion of the insertion wall 30. After passing through the valve seat portion 32, the elastic deformation of the liquid stop valve 44 is restored, and the valve seat portion 32 cannot pass. Thereby, the application body 38 is attached to the inner plug member 18 so as to be able to move up and down a predetermined distance, and does not fall off. The distance through which the liquid stop valve 44 passes through the valve seat portion 32 is short, and is press-fitted from the temporarily placed state, so that assembly is easy.

  After assembly, the guide portion 46 of the application body 38 enters the extended portion 31 of the insertion wall 30 of the inner plug member 18 and guides the vertical sliding, so that the liquid stop valve 44 is not tilted or eccentric. Further, the first convex portion 52 of the application body 38 is slidably inserted into the first groove portion 34 of the inner plug member 18 to prevent the liquid stop valve 44 from being inclined, and the gap around the insertion hole 28. 72 is separated from the outside of the first convex portion 52 to prevent the later-described content liquid from spreading to the periphery when it flows from the insertion hole 28. The second convex portion 54 is slidably opposed to the inside of the second groove portion 36, the elastic body 56 provided in the second convex portion 54 is inserted, and the tip portion 56 a of the elastic body 56 is the bottom portion of the second groove portion 36. The applicator body 38 is urged in a direction away from the inner plug member 18. However, the liquid stop valve 44 of the protrusion 42 of the application body 38 abuts on the valve seat portion 32 of the insertion hole 28 of the inner plug member 18 and does not come off. The liquid stop valve 44 is pressed against the valve seat portion 32 by the urging force of the elastic body 56 and becomes liquid-tight. In this way, in a state where the application body 38 and the inner plug member 18 are assembled, they are transported from the container manufacturer to the pharmaceutical manufacturer that puts the content liquid.

  In the pharmaceutical manufacturer, the content liquid is injected into the container body 12, the inner plug member 18 to which the application body 38 is attached is inserted, the inner cylinder portion 20 is inserted into the spout 14 of the container body 12, and the plate portion 22 of the inner plug member 18 is It is pushed down until it comes into contact with the upper end surface of the spout 14. Then, the cap 60 is covered with the container main body 12 so as to cover the inner plug member 18 and the application body 38, and the female screw 66 of the cap 60 is fitted to the spout 14 male screw 16 of the container main body 12 to be closed. At this time, the convex portion 68 for the inner plug member of the cap 60 is pressed against the side surface portion 24 of the inner plug member 18, and the space between the inner plug member 18 and the container body 12 becomes liquid-tight.

  Next, when the user of the content liquid as the medicine takes out the content liquid from the container 10 with the application body, first, the cap 60 of the container 10 with the application body is unscrewed and removed as shown in FIG. The container 10 with the application body is inverted. At this time, since the liquid stop valve 44 of the protrusion 42 is in contact with the valve seat portion 32 of the insertion hole 28 by the elastic body 56, the liquid content does not come out. And as shown in FIG. 3, the application body 38 is contact | abutted to the to-be-coated surface 70, and the container 10 with an application body is pressed. Then, the elastic body 56 of the application body 38 is elastically deformed and accommodated in the space beside the upright portion 58 and becomes flat, and is pushed in until the application plate 40 of the application body 38 overlaps the upper surface portion 26 of the inner plug member 18. It is. At this time, the first convex portion 52 is inserted to the back of the first groove portion 34, the second convex portion 54 is inserted to the back of the second groove portion 36, the liquid stop valve 44 of the protrusion 42 is separated from the valve seat portion 32, The flow path 50 of the protrusion 42 communicates with the inside of the container body 12. The content liquid stored in the container body 12 passes through the flow path 50 and is poured out from the pouring hole 48 of the coating plate 40 of the coating body 38. The dispensing hole 48 is larger than the inner diameter of the flow channel 50 and is formed so as to be widely applicable. The content liquid adheres to the surface 70 to be coated, and is spread on the coating plate 40 of the coating body 38 by moving the container 10 with the coating body left and right, and is applied to the target area.

  While the content liquid passes through the flow path 50, the content liquid also flows into the gap 72 between the upper surface portion 26 of the inner plug member 18 and the application plate 40 of the application body 38. Since the one groove portion 34 is fitted and closed, it does not spread into the space outside the first convex portion 52. When the use is finished, when the application body 38 is released from the surface 70 to be applied and the pressure of the application body 38 is released, the application body 38 is separated from the inner plug member 18 by the elastic force of the elastic body 56, and the liquid stop valve 44 of the protrusion 42. Comes into contact with the valve seat 32, the flow path 50 is closed, and the content liquid does not come out. The container body 12 is returned to the original upright state, and the cap 60 is screwed to close and stored.

  According to the container 10 with the application body of this embodiment, the content liquid can be reliably made liquid-tight by a simple assembling operation, and the contents are only used when the application body 38 is pressed against the surface to be coated 70 when used. Since the liquid is poured out, even if the container is used in an inverted state, the liquid can be applied without being excessively discharged or dropping off. The container 10 with the application body is simplified in structure by providing a liquid stop valve 44 larger than the insertion hole 28 of the inner plug member 18 at the end of the protrusion 42 of the application body 38. By simply inserting the inner plug member 18 through the insertion hole 28, the application body 38 can be slidably engaged with the inner plug member 18 so as not to fall off, and liquid-tight and release can be switched. The container 10 with an application body has a simple structure, a small number of parts, and is easy to assemble. Therefore, the container 10 has excellent productivity and functionality.

  Since the liquid stop mechanism is formed by a very small surface of a part of the liquid stop valve 44 and a part of the valve seat portion 32, sufficient liquid tightness can be provided even with a small elastic force. For this reason, even if the container 10 with the application body is turned upside down during use, the content liquid does not fall off, and the content liquid is appropriately poured out by simply pressing the application plate 40.

  Further, a first convex portion 52 is provided around the pouring hole 48 of the application body 38, and is slidably inserted into the first groove portion 34 of the inner plug member 18, and a gap 72 around the insertion hole 28. Is separated from the outside of the first convex portion 52, and the content liquid flowing in from the insertion hole 28 moves to the outlet hole 48 without leaking to the outer peripheral portion of the first convex portion 52. It can be used without waste.

  When the application body 38 is attached to the inner plug member 18, the liquid stop valve 44 is inserted to the lower end portion of the expansion portion 31 to be temporarily placed, and then the application body 38 is pushed in to press-fit the liquid stop valve 44. Since the seat 32 is attached through a short distance, it can be easily assembled. Further, after the assembly, the guide portion 46 of the application body 38 enters the insertion wall 30 of the inner plug member 18 to guide the sliding, so that the liquid stop valve 44 does not tilt or decenter.

  Since the elastic body 56 is integrally formed with the application body 38, the number of parts is small, and assembly is easy from this point. The height of the elastic body 56 is set to 1.2 to 2.5 times the moving distance in the projecting and retracting direction of the application body 38, and is set to a short shape for the moving distance in the projecting and retracting direction. The difference between the pressing force when the application body 38 is pushed and the liquid stop valve 44 starts to open and the pressing force when the application body 38 is pushed to the end increases. Here, since the opening between the liquid stop valve 44 and the valve seat portion 32 becomes wider as the application body 38 is pushed in, the opening between the liquid stop valve 44 and the valve seat portion 32 becomes larger as the application body 38 is pushed in. Therefore, the amount of the content liquid dispensed can be appropriately adjusted by adjusting the force for pushing the application body 38 in and out. Four elastic bodies 56 are provided, and the application body 38 is pushed up evenly, so that the application body 38 is kept in a horizontal state without being inclined, and the liquid stop valve 44 is in close contact with the valve seat portion 32 of the insertion hole 28. Can do.

  Further, since the content liquid is poured out from the three pouring holes 48 formed in the coating plate 40, the coating body 38 has less content liquid remaining in the coating body than the coating body made of sponge, for example. There is no clogging, and it is possible to prevent the propagation of germs and the alteration of the content liquid. Even when particles are contained in the content liquid or when the viscosity is high, clogging does not occur. Moreover, it is easy to apply and can be applied comfortably. The pouring hole 48 is formed larger than the inner diameter of the flow path 50, and the content liquid is easy to spread, and can be applied easily without leaking over a wide range.

  In the container 10 with an application body of this embodiment, the elastic body 56 may be provided separately from the application body 38. In the container 74 with the application body shown in FIG. 8, the width of the first groove portion 34 of the inner plug member 18 is formed wider than the first convex portion 52 of the application body 38, and the first convex portion 52 corresponds to the first groove portion 34. The inner peripheral surface is inserted along the inner peripheral surface on the side close to the insertion hole 28, and the inner peripheral surface on the side away from the insertion hole 28 is separated from the first convex portion 52. A recess 76 in which an end of a coil spring 80 described later is set is formed around the inner peripheral surface on the side away from the insertion hole 28 at the bottom of the first groove 34. A recess 78 having the same shape as the recess 76 is formed on the inner side surface 40 b of the application body 38 along the outer periphery of the first protrusion 52. A coil spring 80 is attached between the recess 76 of the inner plug member 18 and the recess 78 of the application body 38. The coil spring 80 is inserted when the application body 38 is assembled to the inner plug member 18, and is compressed by being sandwiched between the application body 38 and the inner plug member 18 when the application body 38 is assembled to the inner plug member 18.

  The use method and effect of the container 74 with the application body are the same as those of the container 10 with the application body except that the elastic body 56 is a separate body. This is suitable when it is necessary or when the application body 38 requires a long stroke.

  Moreover, the container 10 with an application body of this embodiment may be one in which the protrusion 42 is provided as a separate member from the application body 38 and assembled and attached. The container 82 with application body shown in FIG. 9 is integrally provided with an engaging projection 84 for attaching a projection main body 86 to be described later at the center of the inner side surface 40b of the application body 38. The engaging protrusion 84 has a cylindrical shape protruding in a direction away from the inner side surface 40b, and a large-diameter portion 86 having a large diameter on the side peripheral surface is provided at the tip portion. A protrusion main body 88 is attached to the engaging protrusion 84. The protrusion main body 88 is provided with a columnar portion 90 that is inserted into the insertion wall 30 of the inner plug member 18, and an engagement recess in which the engagement protrusion 84 of the application body 38 is engaged with one end surface of the columnar portion 90. 92 is provided. A large-diameter portion 94 into which the large-diameter portion 86 of the engaging protrusion 84 is fitted is provided on the inner peripheral surface of the engaging recess 92. A bulging portion is provided around the end of the cylindrical portion 90 on the side opposite to the engagement recess 92, and a liquid stop valve 96 is provided. The liquid stop valve 96 is provided with an abutting surface 98 that is formed on an inclined surface that is continuous with the side peripheral surface of the cylindrical portion 90 and that approaches the tip as the distance from the cylindrical portion 90 increases. Further, a contact surface 100 that faces the contact surface 98 of the cylindrical portion 90 is formed on the valve seat portion 32 of the inner plug member 18. The liquid stop valve 96 of the projection main body 88 is formed in a size that does not pass through the inside of the valve seat portion 32 of the inner plug member 18.

  Here, the assembly method of the container 82 with an application body is demonstrated. First, the cylindrical portion 90 of the projection main body 88 is inserted into the insertion hole 28 of the inner plug member 18 from the inner cylinder portion 20 side, and the end surface provided with the engagement recess 92 is protruded from the upper surface portion 26. Then, the engagement protrusion 84 of the application body 38 is pressed against the engagement recess 92 of the protrusion main body 88. Then, the large-diameter portion 86 of the engagement protrusion 84 is elastically deformed and inserted into the large-diameter portion 94 of the engagement recess 92, and the elastic deformation is restored and engaged, whereby the assembly is completed. The elastic body 56 of the application body 38 is pushed and elastically deformed, and urges the application body 38 in a direction away from the inner plug member 18. As a result, the projection main body 88 is pulled by the application body 38, and the contact surface 98 of the liquid stop valve 96 comes into close contact with the contact surface 100 of the valve seat portion 32 and becomes liquid-tight.

  The use method and effect of the container 82 with the application body are the same as those of the container 10 with the application body except that the protrusion 42 is a separate member from the application body 38. By being a separate body, it is suitable when the liquid stop valve 96 is thickened to increase the flow rate of the content liquid, or when it is desired to increase the liquid tightness of the liquid stop valve 96.

  The container with the application body of the present invention is not limited to the above-described embodiment, and the shape of each member can be appropriately changed. For example, the liquid stop valve and the valve seat portion are in contact with each other with a small area. Any shape that is surely liquid-tight can be used. The 1st convex part and the 1st groove part should just be a shape which prevents the contents liquid from spreading outside by the shape which can slide mutually. The number and shape of the elastic body can be changed as appropriate, and the height of the elastic body can be changed within a range of 1.2 to 2.5 times the moving distance of the application body. The number of extraction holes and flow paths may be other than three, and the number of protrusions may be a plurality other than one, and the number of insertion holes can be changed according to the number of protrusions. The structure of the coated body may be other than the structure in which the dispensing hole is provided in the coated plate.
