Abstract

PROBLEM TO BE SOLVED: To provide an economical coating filler extruding container with almost no unusable coating filler.
An outer surface of a distal end portion having a discharge port 1c at the distal end of a container 100 is formed as an inclined surface 1a so as to favorably apply to an application portion such as skin, and an elastic body 9 provided at the distal end of a moving body 6. However, when the moving body 6 moves forward to the maximum, the container 100 abuts on the inclined surface 1b of the inner surface of the tip portion having the discharge port 1c at the tip of the container 100, and elastically deforms following the inclined surface 1b. It is possible to sufficiently extrude and consume the filling L for coating remaining in a substantially non-distorted (slanted cylindrical) space (a space including the inclined surface 1b in the tip of the container) by the elastic body 9. .

JP 2004-89687 A

  However, in the above-described apparatus, even if the moving body moves forward to the maximum, a part of the filling for coating remains inside the tip of the discharge lid, resulting in a remaining use.

  The present invention has been made to solve such problems, and an object of the present invention is to provide an economical coating filler extruding container with almost no use of the coating filler.

The coating filler extruding container according to the present invention allows the coating filler filled in the filling region in the container to advance through the discharge port provided at the tip of the container as the moving body disposed in the container advances. In the dispensing container for coating application to be discharged, the outer surface of the tip portion having the discharge port at the tip of the container is an inclined surface, and the inner surface of the tip portion is an inclined surface that is inclined along the outer surface. An elastic body that abuts the inclined surface of the inner surface at the time of maximum advancement of the moving body and elastically deforms following the inclined surface is provided at the tip of the moving body. It is characterized by being rotationally symmetric about an axis .

  According to such a filling material extruding container for application, since the outer surface of the distal end portion having the discharge port at the distal end of the container is an inclined surface, for example, application to an application portion such as the skin is suitably performed and moved. Since the elastic body provided at the tip of the body contacts the inclined surface of the inner surface of the distal end portion having the discharge port at the distal end of the container and moves elastically following the inclined surface when the moving body advances to the maximum, the conventional piston In this case, the filling material remaining in the substantially distorted (obliquely cylindrical) space (the space including the inclined surface inside the container tip) that cannot be pushed out is almost completely left out by the elastic body and consumed. .

  Here, as a specific configuration that effectively exhibits the above-described operation, the container includes a cylindrical body that is rotatably connected to each other and accommodates the movable body, and a movable body that is obtained by relative rotation of these cylindrical bodies. The structure which incorporates the screwing part of the male screw and the female screw which enables the movement of this, and the rotation prevention part of a moving body is mentioned.

  Further, if a space is provided inside the elastic body, the space is easily elastically deformed, and the coating filler is more fully extruded.

Moreover, the said effect | action is show | played effectively as an elastic body is a product made from a silicone rubber. Further, when the outer shape of the elastic body when not deformed is rotationally symmetric about the axis of the moving body, the coating filler can be pressed evenly. The outer shape of the elastic body when not deformed is preferably a bell-shaped or hemispherical shape.

  As described above, according to the filling filler extrusion container for coating according to the present invention, it is possible to provide an economical filling filler extrusion container with little use of the filling filler for coating.

A screwing mechanism (screwing portion) constituted by the female screw 4a of the cylinder 4, a rotation preventing mechanism (rotation preventing part) constituted by the rotation stopper 3b of the shaft body 3a and the rotation stopper 6b of the moving body 6, and the operation cylinder 3 In accordance with the click mechanism constituted by the predetermined engaging portion 3c and the concavo-convex portion 5a of the click spring member 5 and the compression spring portion 5b, the moving body 6 moves forward / backward with a click feeling.

  Hereinafter, the front tube 1 constituting the front half of the coating filler extruding container 100 and the elastic body 9 attached to the tip of the moving body 6 will be described. First, the leading tube 1 will be described in detail.

  The front tube 1 accommodates the filling material L for application, discharges the filling material L for application from the tip portion according to the operation by the user, and the tip portion is applied to the portion to be coated and used for coating. For this reason, the material of the front tube 1 is preferably an injection-molded plastic such as polyethylene terephthalate (PET) or polypropylene (PP), and a transparent material is preferable. When the transparent material is used in this way, even when the cap 7 described later is attached to the front tube 1, it is filled from the appearance through the later-described bulging portion 1d of the front tube 1 exposed without being covered with the cap 7. The color of the applied filling material L can be confirmed.

  As shown in FIGS. 3 to 6, the front tube 1 has a cylindrical shape, and as shown in FIGS. 3 to 5, the outer surface 1 a serving as the application surface of the distal end portion is applied to the application portion such as skin, for example. The inclined surface is inclined with respect to the axial direction of the front tube 1 so as to be suitable for application. Further, as shown in FIG. 5, an inner surface 1b that is an inclined surface that is inclined along the outer surface 1a is formed at the distal end portion of the front tube 1 with a certain thickness from the outer surface 1a. At the same time, a plurality of discharge ports 1c are provided for communicating the inner surface 1b and the outer surface 1a and discharging the filling L for application filled in the front tube 1.

  Further, as shown in FIGS. 3 to 6, the outer surface of the front tube 1 has a bulge whose outer diameter is large so as to abut on the open end of the front end side of the main body tube 2 at a substantially central portion in the axial direction. A protruding portion 1d is provided, and a cap 7 (see FIG. 1) covering the front side of the bulging portion 1d of the front tube 1 is detachably locked in the axial direction at a position near the bulging portion 1d. The protrusions (so-called dowels) 1e are provided at three circumferential positions in the circumferential direction. Further, on the outer peripheral surface of the front tube 1, two convex portions 1f extending in an arc shape along the circumferential direction are formed facing each other at a position on the rear side near the bulging portion 1d. Concave portions 1g extending in an arc shape are respectively provided at the front side, and protrusions 1h extending in the axial direction are formed at four positions in the circumferential direction at the rear end portion. The concave portion 1g and the convex portion 1f (see FIG. 5) arranged side by side in the axial direction are for engaging the front tube 1 with the main body tube 2 in the axial direction. This is for engaging the cylinder 2 in the rotational direction.

  The front tube 1 is inserted into the main body tube 2 from the rear side, and as shown in FIGS. 1 and 2, the rear end surface of the bulging portion 1d abuts on the open end on the front end side of the main body tube 2, and the recess 1g The protrusion 1f engages with an annular protrusion 2a provided on the inner peripheral surface on the distal end side of the main body cylinder 2, and a protrusion 1h is provided on the inner peripheral surface of the main cylinder 2 in the substantially axial direction. By engaging with the knurl 2b having a large number of irregularities, the main body cylinder 2 is mounted so as not to rotate and to move in the axial direction, and is integrated with the main body cylinder 2. Further, a cap 7 can be attached to the front tube 1 as shown in FIG.

  An elastic body 9 is attached to the tip of the moving body 6 via a piston 8. As shown in FIG. 7, the piston 8 has a stepped cylindrical shape with its tip closed, and has an internal shape that accommodates the tip of the moving body 6. The piston 8 has a small-diameter cylindrical portion 8a inserted into the elastic body 9 at the front half, and a large-diameter cylindrical portion 8b connected to the cylindrical portion 8a via a step surface 8c. 1 is a sliding portion that slides in a watertight manner.

  On the inner peripheral surface of the piston 8, annular concave portions 8 d and convex portions 8 e for engaging with the moving body 6 in the axial direction are provided side by side in the axial direction. Further, on the outer peripheral surface of the piston 8, an annular protrusion 8f for engaging the elastic body 9 in the axial direction is provided on the small diameter cylindrical portion 8a, and on the large diameter cylindrical portion 8b, An annular protrusion 8g is provided to adhere to the inner peripheral surface of the front tube 1 and ensure water tightness.

  The elastic body 9 is formed from a soft elastic material such as silicon rubber that is easily elastically deformed. In addition to silicon rubber, thermosetting materials by compression molding such as nitrile rubber (NBR), ethylene propylene rubber (EPR), butyl rubber (IIR), polyurethane elastomer (TPU), polyolefin elastomer (TPO), polyester A thermoplastic material by injection molding such as an elastomer (TPEE) can be selected.

  As shown in FIGS. 8 and 9, the elastic body 9 has a bell shape that is tapered toward the tip, and has a stepped portion that extends from the rear end surface toward the tip as shown in FIG. A concave portion 9a is provided, and an annular concave portion 9b and a convex portion 9c for engaging with the annular protrusion 8f of the piston 8 in the axial direction are provided side by side in the axial direction on the rear side of the concave portion 9a. ing.

  The elastic body 9 is extrapolated to the piston 8 from the rear side, and as shown in FIG. 10, the rear end surface abuts on the step surface 8 c of the piston 8, and the concave portion 9 b and the convex portion 9 c are formed in an annular shape of the piston 8. By engaging with the protrusion 8f, the piston 8 is mounted so as to be rotatable and immovable in the axial direction. In this state, in the elastic body 9, a space 9d is defined on the front half side by the piston 8 that has entered the recess 9a. The space 9d is for promoting elastic deformation of the elastic body 9.

  The piston 8 to which the elastic body 9 is attached is extrapolated from the rear side to the distal end portion of the movable body 6, and the concave portion 8 d and the convex portion 8 e are formed at the distal end portion of the movable body 6 as shown in FIGS. 1 and 2. By engaging with an annular protrusion 6c provided on the movable body 6, the movable body 6 is mounted so as to be rotatable and immovable in the axial direction.

  And, in the filling filler extruding container 100 configured in this way, when the movable body 6 is at its maximum advance, the elastic body 9 is pressed against the inclined inner surface 1b of the front end portion of the front tube 1, Settings such as placement are made.

  According to the filling filler extruding container 100 for application as described above, when the user rotates the main body cylinder 2 or the front cylinder 1 and the operation cylinder 3 relative to each other in the forward direction of the moving body 6, the moving body 6 advances with a click feeling, and the filling L for application filled in the front tube 1 is pushed forward by the elastic body 9 and discharged from the discharge port 1c for application.

  And especially in the filling filler extruding container 100 of the present embodiment, as shown in FIG. 2, when the movable body 6 moves forward by relative rotation by the user, the elastic body 9 It abuts against the inclined inner surface 1b and elastically deforms following the inner surface 1b. At this time, the elastic body 9 is more preferably elastically deformed by the space 9d in the elastic body 9. Due to such elastic deformation of the elastic body 9, almost no coating filling L remains in a substantially distorted (obliquely cylindrical) space (a space including an inclined surface in the tip of the container) that cannot be pushed out by a conventional piston. It is fully extruded and consumed without remaining. For this reason, it is possible to provide an economical coating filler extrusion container 100 in which the coating filler L is hardly left unusable.

  Further, in the filling filler extruding container 100 of the present embodiment, the filling material L is discharged by causing the elastic body 9 to elastically deform and follow the inner surface 1b of the tip portion of the tip tube 1, so that Even if there is a backlash or dimensional error in the part, it is possible to sufficiently absorb the elastic body 9 so as to follow the inner surface 1b by elastic deformation of the elastic body 9, and to sufficiently take out the filling L for coating. is there. Further, when the container 100 is assembled, it is not necessary to strictly align the inner surface 1b and the elastic body 9, and the assembling work is simplified. Furthermore, since the sealing performance is enhanced by the elastic body 9 and the piston 8, it is possible to suppress the backward leakage of the coating filler L when the moving body 6 is pushed out.

  Although the present invention has been specifically described above based on the embodiment, the present invention is not limited to the above embodiment. For example, in the above embodiment, the moving body 6 moves forward / backward. However, instead of the click mechanism, a ratchet mechanism that allows the moving body 6 to rotate in the forward direction may be used.

  Of course, fine hair or the like may be planted on the inclined outer surface 1a of the front tube 1.

  In the above-described embodiment, the extrusion mechanism of the application filler extruding container 100 is a rotary type by the screwing mechanisms 4a and 6a as being particularly suitable. However, for example, a knock type extrusion mechanism or the like may be employed. Is possible.

  The male screw 6a includes a group of protrusions arranged intermittently or a group of protrusions arranged spirally and intermittently, which functions in the same manner as a screw thread. 4a includes a group of protrusions arranged intermittently or a group of protrusions arranged spirally and intermittently, which functions in the same manner as a screw thread.

  The elastic body 9 has a bell shape tapered toward the tip, but the outer shape of the elastic body 9 is not limited to this and may be a hemispherical shape. However, the outer shape of the elastic body 9 does not incline along the inner surface 1b of the front tube 1 when not deformed, but comes into contact with the inner surface 1b when the moving body 6 is fully advanced and follows the inclined surface for the first time by elastic deformation. It is. In addition, from the viewpoint of pressing the coating filler L evenly, the outer shape of the elastic body 9 when not deformed is rotationally symmetric about the axis of the moving body 6 like the above-described bell shape or hemispherical shape. And preferred.
