Description

  The present invention is a cap mounted as a lid on a container body containing a liquid such as a liquid detergent or a liquid bleaching agent, and is a cap used to measure or separate the liquid in the container body for use in small amounts. About.

  There is a cap that is attached as a lid to a container body that contains a liquid such as a liquid detergent or a liquid bleaching agent, and that is used for measuring the liquid in the container body or separating and using the liquid in small amounts. As a method of using this cap, first, liquid is poured from the container main body into the cap, the liquid is transferred from the cap to, for example, a washing tub or a soiled part of the wash, and the cap is remounted on the container main body.

  When the cap is reattached to the container main body, the liquid attached to the peripheral wall of the cap may drip on the outer surface of the container main body, connecting the mounting portion of the container main body.

  As a method of preventing dripping due to re-installation of the cap, the cap is made into a double structure having an inner cylinder portion and an outer cylinder portion, and liquid is poured out from the inner cylinder portion, and the outer cylinder portion is used as the mouth of the container body There is a method in which an annular seal cylinder piece is provided between the inner cylinder part and the outer cylinder part, and the liquid from the inner cylinder part to the outer cylinder part is dammed with this seal cylinder piece (Patent Document 1). .

JP-A-8-48348

  However, it is difficult in terms of cap design to mold the annular seal cylinder piece to a height sufficient to prevent dripping.

  In addition, after pouring the liquid by tilting the cap, if the cap is returned to the upright state (the open end of the inner cylinder part is upward), the liquid adhering to the inner cylinder part is separated from the inner cylinder part and the seal cylinder piece. Therefore, after the cap is reattached to the container body, the liquid spread in the annular groove does not return to the container body and tends to stay. In particular, a highly viscous liquid is difficult to return to the container body. Therefore, when liquid is again poured from the container body into the cap and liquid is poured out from the cap to the washing tub or the soiled area of the wash, the liquid newly adhering to the inner cylindrical portion causes the inner cylindrical portion and the seal cylindrical piece to There was a problem that the liquid overflowed from the groove between them, and when the cap was remounted on the container body in that state, the liquid dropped on the surface of the container body.

  Accordingly, an object of the present invention is to prevent dripping when a cap is remounted on a container body in a liquid container cap used for measuring liquid or using a small amount of liquid.

  The present invention provides a pouring part in the inner cylinder part so that liquid poured out from the cap always passes through the pouring part, and a liquid reservoir part is partially formed at the base of the pouring part. After the liquid is poured out from the liquid, even if the liquid adhering to the inner cylinder part hangs outside the inner cylinder part, the liquid does not spread annularly outside the inner cylinder part, but accumulates at the base of the dispensing part. For this reason, when the cap is reattached to the container main body, the liquid accumulated in the liquid reservoir quickly returns into the container main body, thereby preventing dripping of the liquid in the container main body due to the reattachment of the cap.

That is, the present invention is a cap that is detachably attached to the mouth portion of the container body, and has an outer cylinder portion that is screwed into the mouth portion of the container body, and a bottomed cylindrical inner cylinder that is inside the outer cylinder portion. Part, an annular wall that closes between the end of the outer cylinder part and the cylindrical wall of the inner cylinder part, and an annular seal part formed on the inner surface of the annular wall,
In the inner cylinder part, an extraction part in which the cylindrical wall of the inner cylinder part is partially bent is formed,
Provided is a cap in which a liquid reservoir is partially formed in the base region of the dispensing portion between the cylindrical wall of the inner cylindrical portion and the annular seal portion.

  Moreover, this invention provides the liquid container provided with the container main body which accommodates a liquid, and the above-mentioned cap detachably attached to the opening part of a container main body.

  According to the present invention, since the pouring portion is provided in the inner cylinder portion, the cap user pours the liquid from the pouring portion when pouring the liquid from the cap. After pouring the liquid from the cap, the liquid adhering to the pouring part hangs down to the liquid reservoir at the base of the pouring part. Here, the liquid reservoir is not provided in the entire outer periphery of the inner cylinder part, but is partially provided in the base region of the extraction part. For this reason, the liquid dripping from the inner cylinder part gathers in the liquid reservoir part, and when the cap is remounted on the container body, the liquid quickly returns into the container body.

  Therefore, even after the liquid is again poured out from the cap, the liquid adhering to the pouring portion of the cap does not overflow from the liquid reservoir and is accumulated in the liquid reservoir, and the liquid is prevented from adhering to the inner wall of the outer cylinder portion. The Therefore, it is possible to prevent dripping in the container body caused by reattaching the cap to the container body.

  Hereinafter, the present invention will be specifically described with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.

  FIG. 1A is a perspective view of a cap 1A according to an embodiment of the present invention as viewed from the outside, and FIG. 1B is a perspective view of the cap 1A as viewed from a dispensing portion side. FIG. 2A is a perspective view of the liquid container 100A of the present invention in which the cap 1A is mounted on the container body 20. FIG. For example, various liquids such as a liquid detergent containing a surfactant and a liquid bleaching agent are accommodated in the liquid container 100A.

  As shown in the figure, the cap 1A has an outer cylindrical portion 2 that is screwed into a mouth portion 21 of a container body 20 that contains a liquid, and a bottomed cylindrical shape that is formed in a double cylindrical shape inside the outer cylindrical portion 2. An inner wall 3, an annular wall 5 that closes between the end of the outer cylinder 2 and the cylindrical wall 4 of the inner cylinder 3, and an annular seal portion 6 that is formed on the inner surface of the annular wall 5 with a protrusion. Have. As the annular seal portion 6, a contact 7 made of an annular rib and an inner ring 8 made of an annular wall projecting from the contact 7 on the inner side thereof are provided.

  An inner plug 30 is attached to the mouth portion 21 of the container main body 20, and when the outer cylinder portion 2 of the cap 1 </ b> A is screwed into the mouth portion 21 of the container main body 20, the edge portion of the peripheral wall 31 of the inner plug 30. The above-mentioned contact 7 is pressed against 31a, and the wall surface of the inner ring 8 is in contact with the peripheral wall 31 of the inner plug 30 so that each part is arranged so that the inside of the container body 20 is sealed.

  In the liquid container of the present invention, it is not always necessary to provide the inner plug 30 at the mouth portion 21 of the container main body 20, but it is easy to pour the liquid from the container main body 20 into the cap 1A, From the standpoint of preventing dripping due to outflow, an inner plug 30 having a bowl-like extraction portion 32 and a liquid return hole 33 at the base of the extraction portion 32 as in the container body 20 shown in FIG. 2B. Is preferably provided on the container body 20. In this case, as shown in FIG. 2A, the mouth portion of the container body 20 and the cap 1A may be screwed together, and the inner plug is placed in the mouth portion of the container body 20 as in the liquid container 100B shown in FIG. 30 may be screwed, and the inner plug 30 and the cap 1A ′ may be screwed together.

  The cap of the present invention is a double-cylinder-shaped cap having an outer cylinder part 2 and an inner cylinder part 3, and is an extraction part formed by partially bending the cylindrical wall 4 of the inner cylinder part 3. 9, and a liquid reservoir portion 10 is partially provided in the base region of the extraction portion 9 between the cylindrical wall 4 and the annular seal portion 6 of the inner cylindrical portion 3. More specifically, in the cap 1A of the embodiment, the cylindrical wall 4 of the inner cylindrical portion 3 is bent at a part thereof so that the cross section is substantially V-shaped, and this part allows the liquid to be poured out from the cap 1A. In this case, a pouring part 9 is used as a liquid flow path. Further, in the base region of the extraction portion 9 between the cylindrical wall 4 of the inner cylindrical portion 3 and the annular seal portion 6, the annular wall 5 is partially formed in the vicinity of the bent portion of the cylindrical wall 4. The liquid reservoir 10 is formed by being recessed toward the bottom 3b.

  Therefore, when the liquid container 100A is used, first, the liquid is poured out from the container body 20 into the inner cylindrical portion 3 of the cap 1A, and then the cap 1A is tilted, and the liquid is poured from the dispensing portion 9 into, for example, a washing tub or laundry. When the cap 1A is taken out and returned to the upright state, the liquid A adhering to the cylindrical wall 4 of the inner cylindrical portion 3 drips and accumulates in the liquid reservoir 10 as shown in FIG. Here, the liquid reservoir 10 is not partly around the outer periphery of the inner cylinder part 3 but in the bent region of the cylindrical wall 4 that is the liquid extraction direction, specifically in the base area of the extraction part 9. Thus, the liquid A does not spread into the annular wall 5. For this reason, when the cap 1A is attached to the container main body 20 as shown in FIG. 2A in this state, the liquid A accumulated in the liquid reservoir 10 quickly returns to the container main body 20 through the inner plug 30. Therefore, even if the cap 1 </ b> A is used again thereafter, the liquid A accumulated in the liquid reservoir 10 is discharged, so that the liquid A adhering to the cylindrical wall 4 of the inner cylinder 3 is retained in the liquid reservoir 10. Accumulation and overflow from the liquid reservoir 10 are prevented. Therefore, the liquid A adhering to the cylindrical wall 4 of the inner cylinder part 3 hangs down and spreads in the cap 1A and adheres also to the inner surface of the outer cylinder part 2, and the liquid reattaches the cap 1A to the container body 20. When this occurs, it is possible to prevent dripping of the liquid that hangs down on the surface of the container body 20.

  Moreover, in this cap 1A, the opening end 3a side and the bottom 3b side of the inner cylinder part 3 protrude in the axial direction from the outer cylinder part 2, respectively, and the outer shape of the cylindrical wall 4 of the inner cylinder part 3 on the opening end 3a side The outer shape of the cylindrical wall 4 of the inner cylindrical portion 3 on the bottom 3b side is formed substantially the same. Therefore, the user of the cap 1A can recognize the formation position of the pouring part 9 at a glance from when the cap 1A is attached to the container body 20, and when the liquid is poured out using the cap 1A. The liquid is surely poured out from the dispensing portion 9 of the cap 1A. Therefore, the liquid adhering to the cylindrical wall 4 of the inner cylinder part 3 will adhere to the extraction | pouring part 9, and can collect a liquid more reliably to the liquid storage part 10 of the base area | region of the extraction | pouring part 9. It becomes possible.

  In addition, you may form a knurl as needed in the outer surface of the cylindrical wall 4 by the side of the bottom part 3b of the inner cylinder part 3, and the outer surface of the cylindrical wall of the outer cylinder part 2 as shown in the figure. . Further, in order to measure a predetermined amount of liquid, the inner cylinder portion 3 may be appropriately scaled.

  FIG. 4 is a perspective view of a cap 1B according to another embodiment of the present invention as seen from the outside, and FIG. 4B is a perspective view of the cap 1B as seen from the dispensing portion side.

  This cap 1B is different from the above-described cap 1A in that the annular wall 5 is recessed toward the bottom 3b of the inner cylindrical portion 3 in the base region of the pouring portion 9, and the cylindrical wall 4 of the inner cylindrical portion 3 is replaced with the cap 1B. Outside, the liquid storage wall 11 is juxtaposed with the cylindrical wall 4 of the extraction part 9 so as to surround the base region of the extraction part 9, and the liquid storage wall 11 is arranged at the non-extraction part of the inner cylinder part 3. A region surrounded by the liquid storage wall 11 and the cylindrical wall 4 is formed by being continuous with the cylindrical wall 4, and this is the liquid storage portion 10.

  Thus, in the present invention, the liquid reservoir 10 may be formed by providing a wall parallel to the cylindrical wall 4 that forms the extraction portion 9. Also in this case, after the liquid is poured out from the cap 1B, if the liquid adhering to the cylindrical wall 4 of the pouring portion 9 hangs down, the liquid is poured out without spreading around the entire outer periphery of the cylindrical wall 4. Since the liquid is collected in the liquid reservoir 10 in the base region of the part 9, the liquid can be quickly returned into the container body 20 by reattaching the cap 1 </ b> B to the container body 20. Furthermore, according to the cap 1B, the amount of liquid stored in the liquid reservoir 10 can be made larger than that of the cap 1A.

  FIG. 5 is a perspective view of another cap 1C of the present invention as seen from the outside, and FIG. 5B is a perspective view of the cap 1C as seen from the dispensing portion side.

  In this cap 1C, the cross-sectional shape of the cylindrical wall 4 forming the pouring portion 9 in the cap 1B of FIG. 4 is substantially C-shaped, and the cylindrical wall 4 of the inner cylindrical portion 3 and a liquid reservoir continuous therewith. The outer shape combined with the wall 11 is a cylindrical shape. Thus, the liquid storage wall 11 provided so as to surround the pouring part 9 outside the pouring part 9 can have various shapes.

  A cap 1D in FIG. 6 is obtained by projecting the cylindrical wall 4 of the inner cylindrical portion 3 in a hook shape at a portion where the extraction portion 9 is formed in the cap 1C in FIG. In addition, the extraction part 9 formed in the cylindrical wall 4 can take various shapes.

  The container main body used for the above-described caps 1A to 1D of the present invention and the liquid container of the present invention can be easily industrially manufactured by, for example, an injection molding method using a synthetic resin.

  The cap of the present invention is a cap for a liquid container containing various liquids such as a liquid detergent containing a surfactant, a liquid bleaching agent, etc., for measuring a predetermined amount of liquid from the container body or by dividing it into small portions. It is useful as a cap that is used to apply a small amount to an object such as laundry. Therefore, the liquid container of the present invention provided with such a cap is useful as various liquid containers such as a liquid detergent containing a surfactant and a liquid bleaching agent.
