Description

The present invention relates to a container with a coating body, which contains a content liquid such as a liquid drug, and the contained content liquid is poured out and applied to a target place.

Conventionally, some liquid agents such as anti-itch agents and anti-inflammatory analgesics are stored in a container with an applicator to which an applicator to be applied to the skin is attached. Such a container with a coating body is provided with a valve mechanism so that the liquid does not drip when the container is simply inverted and the liquid can be discharged only when the liquid is applied. Some of such containers with a coating body are provided with a cap to be attached when not in use, and are devised to increase the liquid leakage prevention effect when the cap is closed.

For example, in the liquid coating container disclosed in Patent Document 1, a holding member is attached to the spout of the container body, and an elastic coating member is provided on the outside of the holding member. The cap attached to the mouth and jaw of the container includes a cylinder that is screwed into the outer surface of the mouth and jaw formed by a male screw, a top wall that closes the upper surface of the cylinder, and a hanging cylinder that hangs from the outer periphery of the lower surface of the top wall. It is provided. In this liquid coating container, when the cap is attached, the lower surface of the hanging cylinder comes into liquid-tight contact with the peripheral edge of the holding member, and becomes liquid-tight.

Further, the coating container disclosed in Patent Document 2 has a container body, an inner cap, a coating body, and an outer cap, and has an annular protrusion on the inner surface of the outer cap. In this coating container, when the cap is attached, the annular protrusion closes the discharge port of the coating body from the outside in a liquid-tight manner.

In the case of Patent Document 1 of the above background technology, when a vibration or impact is applied to the container body with the cap closed, the contact between the holding member and the coating member is temporarily released, and the gap between the coating member and the cap is temporarily released. The content liquid may be poured out and accumulated in the container, and may flow out when the cap is removed. Further, when the pressure inside the container becomes higher than the normal pressure due to the expansion of the content liquid or the change in the vapor pressure, there is a problem that the excess liquid is ejected due to the internal pressure of the container body when the content liquid is applied.

Further, in the case of Patent Document 2, since the annular protrusion of the outer cap closes the discharge port of the coating body from the outside in a liquid-tight manner, the coating body and the outer cap can be subjected to vibration or impact even when the container body is subjected to vibration or impact with the cap closed. The content liquid does not collect in the gaps between them. However, the content liquid may collect between the coated body and the inner cap. Further, as in Patent Document 1, when the pressure inside the container becomes higher than the normal pressure due to the expansion of the content liquid or the change in vapor pressure, when the content liquid is applied, the internal pressure of the container body causes the coated body to be coated. There is a problem that excess liquid accumulated between the inner cap and the inner cap is ejected.

The present invention has been made in view of the above-mentioned problems of the background technology, and has a simple structure, bleeds air before pouring out the content liquid, and safely pours out an appropriate amount of the content liquid to a target place.

When the cap is attached to the spout of the container body, the liquid-tight projection comes into liquid-tight contact with one of the coating plate of the coating body and the top surface portion of the cap, and the liquid-tight projection is formed. The coating body is pushed in the sliding direction toward the inner plug member against the elastic force of the elastic body to release the liquid tightness of the liquid stop valve and maintain the liquid tightness of the pouring hole. .. Then, the space between the coating body and the inner plug member is narrowed.

Around the protrusion of the coating body, convex portions projecting in parallel with the protrusion are provided around the protrusion at predetermined intervals, and the tip of the convex portion is provided at the spout of the container body. With the cap attached, it is in contact with the bottom of the annular groove of the inner plug member , and when the cap is moved away from the spout, the coated body is moved by the elastic force of the elastic body.

The inner side surface 62b of the top surface portion 62 of the cap 60 on the coating plate 40 side is provided with a short cylindrical liquid-tightening protrusion 68 that surrounds the central portion of the top surface portion 62. The liquid-tightening protrusion 68 slightly protrudes from the top surface portion 62, and with the cap 60 attached to the spout 14 of the container body 12, protrudes toward the coating surface 40a of the coating plate 40 of the coating body 38 to be liquid-tight. Touch. In this state, three injection holes 48 formed on the coating surface 40a of the coating plate 40 are located and surrounded inside the cylindrical liquid-tightening protrusion 68. On the peripheral edge of the inner side surface 62b near the side surface portion 64, an inner plug fitting recess 70 that abuts on the upper surface 24a of the side surface portion 24 of the inner plug member 18 is provided all around. The inner edge 70a of the annular inner plug fitting recess 70 is formed in an annular shape so as to project so as to be in pressure contact with the upper surface 24a of the side surface portion 24.

Next, a method of assembling the container 10 with a coating body of this embodiment will be described. First, the coil spring 55 of the first groove portion 34 of the inner plug member 18 is inserted, and the protrusion 42 of the coating 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. Insert it near the lower end of 31. Then, the liquid stop valve 44 of the protrusion 42 comes into contact with the upper surface of the narrowly formed portion of the upper portion of the valve seat portion 32, and is in a temporary placement state (preset). Next, the coating body 38 is further pushed into the inner plug member 18 side with a strong force equal to or higher than a certain level. Since the liquid stop valve 44 of the protrusion 42 is larger than the inner diameter of the valve seat portion 32, it cannot pass through in contact with the liquid stop valve 44. It is deformed and enlarged, and 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 liquid stop valve 44 cannot pass through the valve seat portion 32. As a result, the coating body 38 is attached to the inner plug member 18 so as to be able to advance and retreat a predetermined distance, and does not fall off. Since the distance through which the liquid stop valve 44 passes through the valve seat portion 32 is short and the liquid stop valve 44 is press-fitted from the temporarily placed state, assembly is easy.

After assembly, the guide portion 46 having a large diameter of the coating body 38 enters the expansion portion 31 of the insertion wall 30 of the inner plug member 18 to guide the vertical sliding, and the liquid stop valve 44 tilts or eccentric. Never. Further, the first convex portion 52 of the coating body 38 is slidably inserted into the insertion wall 30 side of the first groove portion 34 of the inner plug member 18 to prevent the liquid stop valve 44 from tilting. Further, the tip portion 52a of the first convex portion 52 is in contact with the bottom portion 34a of the annular first groove portion 34 of the inner plug member 18 in a state where the cap 60 is attached to the spout 14 of the container body 12. When the cap 60 is moved away from the spout 14, the coating body 38 is pushed toward the cap 60 by the elastic force of the coil spring 55, and the tip portion 52a of the first convex portion 52 and the first groove portion of the inner plug member 18 are formed. Contact with the bottom 34a of 34 is released.

Further, the cylindrical space 53 formed between the peripheral surface of the first groove 34 on the second groove 36 side and the first convex portion 52 of the coating body 38 is wound in a cylindrical shape having a constant thickness. Since the coil spring 55, which is an elastic body, is fitted, the coating 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 coating body 38 comes into contact with 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 coil spring 55, and is provided so as to be able to switch between a liquid-tight state and an open state. In this way, with the coating body 38 and the inner plug member 18 assembled, the container maker conveys the content liquid to the pharmaceutical manufacturer.

In a pharmaceutical manufacturer, the content liquid is injected into the container body 12, the inner plug member 18 to which the coating body 38 is attached is inserted, and the inner cylinder portion 20 is inserted into the injection port 14 of the container body 12, and the plate portion 22 of the inner plug member 18 is formed. Attach by pushing down until it comes into contact with the upper end of the spout 14. Then, the cap 60 is put on the container body 12 so as to cover the inner plug member 18 and the coating body 38, and the female screw 66 of the cap 60 is screwed into the male screw 16 of the injection port 14 of the container body 12 to close the container body 12. In this state, the tip portion 52a of the first convex portion 52 is pressed against the bottom portion 34a of the annular first groove portion 34 of the inner plug member 18, and the liquid-tight projection 68 of the cap 60 is the coating plate 40 of the inner plug member 18. The gap 74 formed between the coating body 38 and the coating body 38 around the injection hole 48, which abuts on the coating surface 40a, is separated from the outside of the liquid-tightening protrusion 68. Further, even if the inner edge 70a of the annular inner plug fitting recess 70 is pressed against the upper surface 24a of the side surface 24 and the content liquid described later is poured out from the pouring hole 48, the inside of the top surface 62 It prevents the retained content liquid from spreading from between the coating plate 40 and the top surface portion 62 to the outer peripheral portion.

When the cap 60 is attached to the container body 12 and tightened, the coating body 38 is pushed and pushed by the liquid-tightening protrusion 68 of the cap 60, and the liquid stop valve 44 of the protrusion 42 is the valve seat portion 32 of the inner plug member 18. The liquidtightness is released. The content liquid contained in the container body 12 flows into the gap 74 between the coating plate 40 and the cap 60 through the insertion hole 28 of the inner plug member 18, the flow path 50 and the injection hole 48 of the coating body 38. However, since the liquid-tightening protrusion 68 of the cap 60 is in pressure contact with the coating plate 40 coating surface 40a of the inner plug member 18, the content liquid is sealed in the gap 74 and does not flow to the outside. Further, the tip portion 52a of the first convex portion 52, the middle since the pressure contact with the bottom 34a of the annular first groove 34 of the plug member 18, the inside plug member 18 from the insertion hole 28 and the insertion wall 30 of the first convex The content liquid that has flowed in through the gap of the portion 52 does not flow out to the outside of the first convex portion 52. Further, the edge 70a of the recess 70 for the inner plug member of the cap 60 comes into contact with the upper surface 24a of the side surface portion 24 of the inner plug member 18, and the space between the inner plug member 18 and the cap 60 becomes liquidtight. Therefore, in the state where the cap 60 is tightened and attached, even if the container body 12 is tilted, the content liquid contained in the container body 12 does not come out, and the container 10 with the coating body can be safely transported and stored. be able to.

Next, a method of using the container 10 with a coating body will be described. When the content liquid is taken out from the container body 12 and used, first, the cap 60 is turned around the shaft to release the screw of the female screw 66 and the male screw 16 and remove the cap 60. In the process of removing the cap 60, the force holding the coating body 38 is released, and the coating body 38 is urged by the coil spring 55 to rise. Since the protrusion 42 of the coating body 38 is slidably fitted in the insertion hole 28 of the inner plug member 18, the sliding direction is along the axial direction of the protrusion 42. As shown in FIG. 2, when the screw between the cap 60 and the container body 12 is gradually released and the cap 60 rises slightly, the coating body 38 is also urged by the coil spring 55 and rises, but the liquid stop valve of the protrusion 42 Until the 44 comes into contact with the valve seat portion 32 of the inner plug member 18, the flow path 50 of the coating body 38 communicates with the container body 12 and the gradually expanding gap 72, and the inside and outside of the container body 12 are ventilated. It is secured. As a result, even if the pressure inside the container body 12 rises due to the temperature difference during storage, when the cap 60 is opened, the space around the insertion hole 28 of the inner plug member 18 is first decompressed to bleed air. The inside of the container body 12 becomes equal to the atmospheric pressure.

Further, the cap 60 is turned around the shaft to release the screw, and when the cap 60 is removed, the coating body 38 is pushed up by the coil spring 55, and the liquid stop valve 44 of the protrusion 42 comes into contact with the valve seat portion 32 of the inner plug member 18. , The protrusion 42 does not move any further and stops. Then, the flow path 50 of the coating body 38 is closed, and the content liquid is not poured out.

Then, the container body 12 is inverted in this closed state. At this time, as shown in FIG. 3, the content liquid does not come out. Then, as shown in FIG. 4, the coated body 38 is brought into contact with the surface to be coated 76, and the container 10 with the coated body is pressed against it. Then, the coil spring 55 is elastically deformed, and the first convex portion 52 of the coating body 38 is inserted all the way into the first groove portion 34 of the inner plug member 18, and the second convex portion 54 is inserted all the way into the second groove portion 36. The liquid stop valve 44 of the protrusion 42 is separated from the valve seat portion 32, and the flow path 50 of the protrusion 42 passes inside the container body 12. The content liquid contained 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 injection hole 48 is larger than the inner diameter of the flow path 50 and is formed so that it can be widely applied. The content liquid adheres to the surface to be coated 76, and by moving the container 10 with the coating body left and right, it is spread by the coating plate 40 of the coating body 38 and applied to a target area.

While passing 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 coating plate 40 of the coating body 38, but the gap 72 is formed between the first convex portion 52 and the first convex portion 52. Since the 1 groove portion 34 is fitted, the groove portion 34 does not spread to the outside of the first convex portion 52. When finished using, when the coating body 38 is separated from the surface to be coated 76 and the pressure of the coating body 38 is released, the coating body 38 is separated from the inner plug member 18 by the elastic force of the coil spring 55, and the liquid stop valve 44 of the protrusion 42 is released. It comes into contact with the valve seat portion 32, the flow path 50 is closed, and the content liquid does not come out. Return the container body 12 to the original upright state, screw the cap 60 to close it, and store it.

According to the container 10 with a coating body of this embodiment, the container body 12 has a simple structure, and the air inside the container body 12 is evacuated in the middle of the operation of opening the cap 60 before the content liquid is poured out, so that an appropriate amount of the content liquid is dispensed. It can be safely poured to the desired location. It is safe because excess liquid does not spurt out when applying the content liquid.

Further, when the cap 60 is closed and stored, the content liquid can be surely made liquid-tight. Even if the content liquid comes out of the pouring hole 48 of the coating body 38 due to a fall or drop with the cap 60 closed, it is sealed in the gap 74 surrounded by the liquid-tightening protrusion 68 of the cap 60 and inside the cap 60. It does not spread over a wide area of the cap 60 and does not leak out of the cap 60. Further, in the state where the cap 60 is closed, the first convex portion 52 of the coating body 38 is deeply inserted into the first groove portion 34 of the inner plug member 18, and the gap 72 between the coating body 38 and the inner plug member 18 becomes smaller. The amount of the content liquid that collects between the plug member 18 and the coating body 38 can be suppressed to a small size, and the content liquid does not spread to the outside of the first convex portion 52 between the inner plug member 18 and the coating plate 40. Therefore, it is possible to minimize the amount of fluid that can flow between the inner plug member 18 and the coating plate 40.

When the content liquid is taken out from the container body 12, the content liquid is poured out only when the coating body 38 is pressed against the surface to be coated 76. An appropriate amount can be applied without dropping.

The structure of the container 10 with a coating body 10 is simplified 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 coating body 38, so that the protrusion 42 of the coating body 38 is provided. By simply inserting the coating body 38 into the insertion hole 28 of the inner plug member 18, the coating body 38 can be slidably locked to the inner plug member 18 so as not to come off, and can be switched between liquid tightness and release. Further, since the container 10 with a coating body has a simple structure, a small number of parts, and is easy to assemble, it is excellent in productivity and functionality.

Further, since the metal coil spring 55 is used to urge the coating body 38, the coating body 38 is surely pushed up and the liquid stop valve 44 of the protrusion 42 is brought into close contact with the valve seat portion 32 of the inner plug member 18. You can prevent dripping. The coil spring 55 is also suitable when it maintains elasticity even when stored for a long period of time under a load, the elastic force does not change with time, and the coated body 38 requires a long stroke.

Further, when the cap 60 is closed, the recess 70 for the inner plug member of the cap 60 comes into contact with the upper surface 24a of the side surface portion 24 of the inner plug member 18, so that the liquid content can be reliably prevented from leaking and the cap 60 can be closed. Even if the coating body 38 and the inner plug member 18 are tightened with an excessive torque, an excessive load is not applied to the coating body 38 and the inner plug member 18.

The container with a coated body of the present invention is not limited to the above embodiment, and the shape of each member can be changed as appropriate. For example, the number of injection holes and flow paths may be other than three. The liquid-tight protrusion of the cap may be provided on the surface of the coating plate, and may be provided so as to surely surround the injection hole. The liquid stop valve and the valve seat portion may have a shape in which they come into contact with each other in a small area to ensure liquid tightness. The first convex portion and the first groove portion may also have a shape that allows them to slide with each other and prevent the content liquid from spreading to the outside. In addition, it may be used as long as it contains chemicals, cosmetics, and other liquids and takes out an appropriate amount.
