FIG. 4 is a longitudinal sectional view of the coating plug showing a state where the overcap is removed. In FIG. 2, the locking member 30 and the screwing member 40 are indicated by solid lines, and the nozzle 7, the backless valve 50, the mouth tube portion 2, and the overcap 60 positioned on the outer edge side are indicated by broken lines. Is shown.

  The application container of the present invention contains fluid contents, for example, cosmetics and chemicals such as emulsion, cooking oil (salad oil, olive oil, etc.), etc., and the surface of the skin and cooking utensils (eg frying pan), etc. An application stopper comprising a container main body 1 that is provided with a dispensing nozzle 7 and that can be squeezed, and an application body 20 that applies the contents in contact with the application object. 10 and an overcap 60 that is fitted on the head of the container body 1 and covers the nozzle 7 and the coating plug 10, and is entirely formed of a synthetic resin material.

The container body 1 is typically a tube container, a squeeze container, or the like. However, the container body 1 is limited to these containers as long as the body portion 4 can be easily deformed by a pressing operation and the contents inside can be poured out. It is not a thing.
The container body 1 has a mouth tube portion 2 erected on the shoulder portion 3, and a thread 2 a is engraved on the outer peripheral surface of the mouth tube portion 2. A valve seat portion 5 continuing from the shoulder portion 3 is formed in the bottom portion in the mouth tube portion 2, and a discharge port 6 having a small diameter is formed in the center of the valve seat portion 5.

  The nozzle 7 has a short cylindrical base portion 7b inserted into the mouth tube portion 2 on the lower side of the flange 7c, and a nozzle body 7a formed on the upper side of the flange 7c with a reduced diameter toward the tip. A pouring hole 7d is formed at the tip of the nozzle body 7a.

  The coating plug 10 holds the coating body 20 sandwiched between the coating body 20 that coats the contents to be coated, the locking member 30 that locks the coating body 20, and the locking member 30. At the same time, it has a screwing member 40 that can be attached to and detached from the screw 2a of the mouth tube portion 2 by screwing.

  The application body 20 shown in the first embodiment is a substantially columnar member made of a soft porous body such as foamed urethane or rubber. A through hole 21 into which the nozzle body 7a is inserted is formed at the center of the application body 20, and a locking groove 22 having a ring shape is formed at a position below the side surface of the application body 20. The application body 20 is used in a state in which the upper end portion 23 is pressed against an application target such as skin, and applies the flowable content extracted from the extraction hole 7d of the nozzle 7 to the application target. .

  The locking member 30 is a substantially cylindrical member, and a plurality of support portions 32 projecting from the center are provided at a substantially central height position of the inner surface of the side wall 31. An annular locking ring 33 is connected. Then, the application body 20 can be locked by the engagement ring 33 engaging the locking groove 22 formed on the side surface of the application body 20. The inner diameter dimension of the locking ring 33 is slightly smaller than the outer diameter dimension of the locking groove 22 formed on the side surface of the application body 20, and the application body 20 has a diameter relative to the locking ring 33. It is hard to come off because it is inserted in a biased state toward the outside in the direction.

  At a position below the inner surface of the side wall 31 of the locking member 30, a first locking projection 34 having a circular arc shape is projected. As shown in FIG. 2, the first locking projection 34 has a constant central angle, and is arranged at a plurality of locations (four locations in FIG. 2) on the inner surface of the side wall 31 with a constant spacing in the circumferential direction. ing.

  As shown in FIG. 1, the screwing member 40 is a member having a double wall structure having an inner wall 41 and an outer wall 42 each having a substantially cylindrical shape. The inner wall 41 and the outer wall 42 are flanges on the lower end side. The parts 43 are connected. The lower end of the flange portion 43 is a skirt portion 44 in which the outer wall 42 protrudes sideways. A screw thread 41a is formed on the inner surface 41A of the inner wall 41 to be screwed with the screw thread 2a of the mouth tube portion 2, and a disk-shaped top plate 41C having a round center and an open hole is connected to the upper end. The top surface of the top plate 41 </ b> C is a portion that supports the bottom surface of the application body 20, and the positional displacement of the application body 20 is prevented by roughening the top surface.

  A substantially cylindrical gap S is formed at a portion where the outer surface 41B of the inner wall 41 and the inner surface 42A of the outer wall 42 are opposed to each other in the radial direction. As shown in FIG. 2, a second locking convex portion 41 b having an arc shape protrudes in the cylindrical gap S on the outer surface 41 </ b> B of the inner wall 41. The second locking projections 41b are formed with a constant central angle θ2, and are arranged at a plurality of locations (four locations in FIG. 2) on the outer surface 41B of the inner wall 41 with a constant spacing in the circumferential direction. ing.

  The locking member 30 that locks the application body 20 is inserted with the lower end of the side wall 31 downward into a cylindrical gap S formed between the inner wall 41 and the outer wall 42 of the screwing member 40. At this time, the first locking projections 34 on the locking member 30 side are engaged with each other by descending over the second locking projections 41b on the screwing member 40 side (undercut locking). ).

  The central angle θ2 of the second locking projection 41b is the circumferential gap α formed between one first locking projection 34 and the other first locking projection 34 adjacent in the circumferential direction. It is formed at an angle larger than the central angle θα. As a result, the first locking projection 34 and the second locking projection 41b can be locked without being positioned in the circumferential direction. The setability and productivity with the joint member 40 can be improved. Even if the first locking projection 34 and the second locking projection 41b are displaced in the circumferential direction, the locking state of the both is not released, and the locking member 30 is separated from the screwing member 40. It becomes impossible. Moreover, in this state, the application body 20 is sandwiched and held between the locking member 30 and the top plate 41 </ b> C of the screwing member 40.

  As shown in FIG. 1, a backless valve 50 is provided in the mouth tube portion 2. The backless valve 50 includes a cylindrical valve base 51, a thin deformed portion 52 connected to the bottom side of the valve base 51, and a disc-shaped valve body 53 that swings around the thin deformable portion 52 as a fulcrum. Consists of. The backless valve 50 has a valve base 51 fitted into the inner wall of the mouth tube portion 2, and a valve body 53 partitions the discharge port 6 formed in the valve seat portion 5 so as to be freely opened and closed. The backless valve 50 is movable so as to close the discharge port 6 from the mouth tube part 2 side to the body part 4 side of the container body 1. Accordingly, it is possible to prevent the contents remaining in the mouth tube portion 2 from being sucked into the container body 1 when the inside of the body portion 4 becomes negative pressure.

  The overcap 60 is a cylindrical member having a top wall 62 on the side wall 61, a tubular sealing plug 63 is suspended from the lower surface of the top wall 62, and is locked to the bottom of the side wall 61. A piece 64 is formed. Then, as shown in FIG. 1, when the overcap 60 is fitted on the head of the container body 1 to cover the application plug 10 provided with the application body 20, the locking piece 64 of the side wall 61 constitutes the application body 20. It is engaged with and held by a locked portion 42 b formed on the outer surface of the outer wall 42 of the screwing member 40. At the same time, the sealing plug 63 is inserted into the through-hole 21 of the application body 20, and the tip of the sealing plug 63 covers the nozzle body 7 a and seals the extraction hole 7 d, so that the contents leak out. It can be prevented.

When the overcap 60 is lifted, the engagement between the locking piece 64 and the locked portion 42b is released, so that the coating plug 10 provided on the head of the container body 1 can be exposed. At the same time, since the exterior of the nozzle body 7a by the sealing plug 63 is also released, the pouring hole 7d can be opened.
Therefore, when the user squeezes the body 4 to increase the internal pressure in the body 4, the valve body 53 is pushed up and the discharge port 6 is opened, so that the fluid content is discharged from the container body 1. The application body 20 can be poured out from the tip of the nozzle 7 through the outlet 6 and the mouth tube portion 2. Therefore, the user can apply the contents by sliding the upper end portion 23 of the application body 20 in contact with an application target such as the surface of the skin.

  When the contents are cosmetics such as emulsion, it is necessary to prepare the application body 20 such as a puff and the container main body 1 in which the emulsion is stored, but in the application container, the application body 20 is the container main body. Since it is integrally stored in one head, it can be conveniently carried. Further, since the user only needs to remove the overcap 60 and squeeze the body part 4, the application body 20 and the container body 1 can be applied easily compared to different configurations. Moreover, since the application plug 10 is detachably connected to the container body 1 through the screwing member 40, the application plug 10 is applied in a state where the upper end portion 23 of the application body 20 is in contact with the application target. During application, the application body 20 does not come off the application plug 10 that is held between the locking member 30 and the screwing member 40.

  Further, as described above, since the screwing member 40 constituting the coating plug 10 is detachably connected to the mouth tube portion 2 by screwing, when the coating plug 10 is to be removed from the container body 1, the coating plug 10 is removed. It can be easily removed by a simple operation of rotating (see FIG. 3). Therefore, the contents in the container body 1 can be directly poured out from the dispensing hole 7d at the tip of the nozzle 7 toward the application target.

  Further, as shown in FIG. 4, the application body 20 can be exposed by further removing the overcap 60 from the state shown in FIG. 3, so that the application body 20 can be easily washed.

  Further, after the contents are used up, the coating stopper 10 can be removed from the empty container body 1 and replaced with a new container body 1 to be used as a refill container.

Next, another embodiment of the present invention will be described.
