Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the mouth of a tube in which a relatively viscous content such as cream is spread directly from a tube container onto an application target part such as the skin.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 9, the tube mouth of a tube container filled with highly viscous contents such as cream has a wide discharge passage (1) for the contents and a small discharge mouth (2) for the contents. It is known that a circle is provided.

The tube mouth (3) is provided with a screw portion (5) for mounting the cap (4) on the outer circumference. The screw portion (5) is formed in a rib shape thicker than other portions of the mouth main body (6) and is strong, so that the tube mouth (3) is deformed by external pressure. It becomes difficult to do. Therefore, the contents remaining in the discharge passage (1) at the mouth of the tube (3) cannot be pushed out from the discharge outlet (2) even if pressed from the outside, and the contents remain in the wide discharge passage (1). It had the uneconomical property of leaving a large amount of residue.

In addition, the conventionally known mouth has a problem that it is not possible to apply the content to the application target portion in a wide and efficient manner.

Further, as the one used to apply a highly viscous content such as cream directly from a tube container to an application target portion such as skin, as shown in FIGS. 10 and 11, the discharge port (2) is used. It is known that the above is formed into a long hole shape. The elongated hole-shaped discharge port (2) has an advantage that the content can be extruded in a wide range and can be applied to the application target portion in a wide and wide area.

However, like this tube mouth (3), the tube mouth (3) also has a screw portion (5) for mounting the cap (4) on the outer circumference. Since the maximum inner diameter of the discharge passage (1) is formed larger than the maximum inner diameter of the discharge outlet (2), the internal volume of the non-deformable discharge passage (1) becomes large, and If the size in the length direction of 2) is made large so that a wide coating can be formed, there is a disadvantage that the amount of contents remaining in the discharge passage (1) increases.

Further, since the elongated hole-shaped discharge port (2) of the tube mouth (3) projects like a beak, the content applied to the application target portion can be widely spread in the mouth body (6). It was inconvenient to spread.

[0008]

[Problems to be solved by the device]

 The present invention is intended to solve the above-mentioned problems, and makes it possible to spread a highly viscous content such as cream directly from a tube container to a wide range of intended application areas such as the skin. At the same time, the amount of remaining contents in the discharge passage is reduced.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention forms a discharge passage for the contents communicating with the mouth portion in the mouth main body that is connected and fixed to the mouth portion of the tube container, and applies the discharge passage to the mouth main body. Communicating with the coating port that opens to the side, the maximum inner diameter of this coating port is made larger than the maximum inner diameter of the discharge path, and the coating surface that contacts the target coating part on the surface of the mouth main body around the coating port. Is provided, and the coating surface is formed to be flat or have the same curvature surface.

[0010]

[Action]

 Since the present invention is configured as described above, in order to widely spread the contents of the tube container on the application target part of the skin or the like, hold the tube container with your fingers and place the application port on the skin or the like. Press the tube container while gently touching the application target area. By this pressing, the contents are discharged from the coating port to the coating target portion through the discharging passage. In this state, by moving the application port along the application target part while pressing the tube container, the content can be applied to the application target part within the width of the maximum inner diameter dimension of the application port.

Further, since the coating surface that contacts the coating target portion is formed to be flat or the same curvature surface on the surface of the mouth main body around the coating port, coating between the coating surface and the coating target portion is performed. By moving the tube container along the application target portion while interposing the above-described content, the content can be widely spread on the application target portion. That is, if the coating surface is flat or has the same curvature, no unevenness will occur on the coating surface. Therefore, if the coating surface is moved along the target portion of the coating, there will be little change in coating thickness etc. due to this coating surface. Can evenly apply the contents. In addition, since no unevenness is generated, the contents do not remain on the coated surface, which enables efficient coating of the contents.

Further, since the maximum inner diameter of the coating port is formed wider than the maximum inner diameter of the discharge passage, the remaining amount of the content in the discharge passage is smaller than the width of the content that can be applied. Therefore, while a large coating port enables efficient coating of a large width, the remaining amount relative to this coating width is reduced to enable economical use.

【Example】

 A first embodiment of the present invention will be described below with reference to FIGS. 1 and 2. (20) is a mouth body which is connected and fixed to a mouth portion (22) of a tube container (21). This connection consists of an annular step (23) formed on the outer circumference of the mouth (22) of the tube container (21) and an annular recess (25) formed on the inner circumference of the inner cylinder (24) of the mouth body (20). It is done by engaging. Further, as this connection method, any method can be selected. For example, the mouth main body (20) is screwed into the mouth portion (22) of the tube container (21), or the tube container (20). The mouth main body (20) may be adhered to the mouth portion (22) of (21) with an adhesive or the like.

In addition, the mouth body (20) axially forms a discharge passage (26) of the content communicating with the mouth portion (22) of the tube container (21), and the discharge passage (26) is formed in the discharge passage (26). The application port (27) communicating with the opening is opened in the top plate of the mouth main body (20). This coating port (27) has a maximum inner diameter in the length direction larger than the maximum inner diameter of the discharge passage (26) and a width direction smaller than the inner diameter of the discharge passage (26). It is formed into a shape. Further, the top plate of the mouth main body (20) around the outer periphery of the coating port (27) is formed flat so as to serve as the coating surface (28) of the contents.

Further, an outer cylinder (32) is formed on the outer circumference of the inner cylinder (24) of the mouth body (20) via an outer circumference interval (29), and a screw part (32) is formed on the outer circumference of the outer cylinder (32). 33) is formed. Then, the cap (34) is screwed into the mouth main body (20) through the screw portion (33). The cap (34) is provided with an annular contact ring (35) at a position corresponding to the application surface (28) of the mouth main body (20). By forming the contact ring (35) so that it can contact the application surface (28), the application port (27) is closed when the cap (34) is screwed into the mouth main body (20).

In the structure configured as described above, in order to widely spread the contents (37) in the tube container (21) on the application target part (36) such as skin, the tube container (21) is used. Hold it with your fingers and press the tube container (21) while lightly touching the application target part (36) such as the skin with the application port (27). By this pressing, as shown in FIG. 5, the content (37) is discharged from the coating port (27) to the coating target portion (36) through the discharge passage (26). In this state, while pressing the tube container (21), the coating port (27) is moved along the coating target portion (36) in a direction intersecting the length direction of the coating port (27). By this movement, the content (37) can be applied to the application target portion (36) within the width of the application port (27) in the lengthwise direction.

Further, since the top surface of the mouth main body (20) around the outer periphery of the coating port (27) is formed with a flat coating surface (28) which comes into contact with the coating target portion (36), this coating surface ( By moving the tube container (21) along the application target part (36) while interposing the applied content (37) between the application target part (36) and the application target part (36), The contents (37) can be spread over a wide area (36). That is, if the coating surface (28) is made flat, no unevenness is generated on the coating surface (28), so if the coating surface (28) is moved along the coating target portion (36), By (28), the contents (37) can be uniformly applied in a state where the change in the applied thickness is small. Further, since the unevenness does not occur, the content (37) does not remain on the application surface (28), and the content (37) can be efficiently applied.

Further, since the coating surface (28) that contacts the coating target portion (36) is formed flat, the contact ring (35) that can contact the coating surface (28) is attached to the cap (34) top plate. If it is formed on the inner surface, the contents (37) can be sealed and stored. Therefore, it is not necessary to provide a stopper or the like for sealing the contents (37) separately from the cap (34), and the assembly process can be simplified. In addition, even when in use, there is no inconvenience such as accidentally losing the stopper.

Further, since the maximum inner diameter of the coating port (27) is formed wider than the maximum inner diameter of the discharge passage (26), the discharge passage is compared with the width of the content (37) which can be applied. The remaining amount of the contents (37) in (26) is small, and while the large coating port (27) enables efficient coating of a large width, the remaining amount relative to this coating width is reduced. Allows economical use.

Further, in the first embodiment, the slot-shaped coating port (27) is opened in the top plate of the mouth main body (20). However, in the second embodiment, as shown in FIG. 3, an opening having the same diameter as the discharge passage (26) may be formed at the center of the elongated hole-shaped application port (27). By forming in this way, as shown in FIG. 8, the insertion rod (38) is formed at the center of the back surface of the top plate of the cap (34), and the discharge passage (26) can be sealed more reliably.

Further, in the third embodiment, as shown in FIG. 4, the coating port (27) is formed in a circular shape having an inner diameter larger than the maximum inner diameter of the discharge passage (26). By forming in this way, like the second embodiment, the discharge path (26) can be sealed by the insertion rod (38), the movement direction of the mouth main body (20) is not restricted, and the application is performed. A wide coating can be achieved by moving the coating port (27) in any direction along the target portion (36).

Further, in the first to third embodiments, the coating surface (28) is formed flat, but in different embodiments, it may be formed into a curved surface. In this case, the coating surface (28) is preferably formed to have the same curvature surface, for example, it may be an arc-shaped dome surface as shown in FIG. 6 or a tapered inclined surface as shown in FIG. It is a good one.

[0023]

[Effect of the device]

 Since the present invention is configured as described above, the residual amount of the content in the discharge passage is reduced as compared with the width of the content that can be applied, and highly viscous content such as cream can be directly applied from the tube container to the skin or the like. It is possible to spread a wide range of the target application area, while the remaining amount of the content in the discharge passage can be made relatively small, which enables economical use.

Further, since the coating surface is formed to be flat or has the same curvature surface on the outer periphery of the coating port, the coating can be performed while the contents are interposed between the coating surface and the coating target portion, and a wide coating can be performed. It is easily possible.
