Description

  The present invention relates to a cap attached to the mouth of a bottle-shaped container body.

  As a container for storing a liquid material such as dressing, sauce, sauce, edible oil, etc., a bottle-shaped container body with a cap provided with an inner stopper is used.

  In such a container, the container is sufficiently shaken before use of the content liquid, so that the content liquid is in a substantially uniform dispersion state. For this reason, when the cap is opened after shaking, the content liquid adhering to the inside of the top surface of the cap spills on the outer wall of the cap, or when the cap is closed again, the content liquid adhering to the cap is removed from the container body. The problem of dripping on the outer wall is likely to occur.

  For this, it is a cap consisting of a cap body that is directly attached to the mouth of the container body and serves as an inner plug, and a lid that is hinged to the cap body and opens and closes the opening of the cap body. There has been proposed a structure in which a pouring cylinder is protruded from the main body, and a plurality of ribs formed in a chevron and a chevron are fitted inside the top surface of the lid (patent document 1). ).

JP-A-9-12049

  However, the above-mentioned cap can hold a large amount of content liquid between a large number of ribs formed inside the top surface of the lid, so that if the container is shaken, the content liquid that adheres to the top surface of the lid is unnecessary. There was a problem of increasing.

  On the other hand, the present invention reduces the amount of content liquid adhering to the lid itself after shaking of the container as much as possible in a container with a cap attached, and when opening the cap after shaking, The content liquid adhering to the container is held by the lid so that when the cap is opened, the liquid content leaks to the outer wall of the cap, or when the cap is closed again, The purpose is to prevent the problem.

In order to achieve the above-mentioned object, the present invention is a cap comprising a cap body attached to the mouth of the container body, and an upper lid screwed onto the cap body,
The cap body has a dispensing tube protruding from the upper surface,
The upper lid has an annular cylinder pressed against the inner wall of the upper end of the dispensing cylinder in a state where the upper lid is attached to the cap body, and a radial liquid guide rib in a region surrounded by the annular cylinder,
The radial liquid guide rib has a plurality of heights that increase from the peripheral edge of the annular cylinder toward the center of the radial liquid guide rib, and wide from the center of the radial liquid guide rib toward the peripheral edge of the annular cylinder. A cap comprising rib pieces arranged radially is provided.

  According to the cap of the present invention, the radial liquid guide rib is formed in the region surrounded by the annular cylinder inside the top surface of the upper lid, and the radial liquid guide rib is formed at the center of the radial liquid guide rib from the peripheral edge of the annular cylinder. Since the plurality of rib pieces having a height that increases toward the portion and increases in width from the central portion of the radial liquid guiding rib toward the peripheral portion on the annular tube side are arranged radially, When attached to the main body and the container is set upright, the top of the central portion of the radial liquid guiding rib hangs down to the container main body. Therefore, by attaching this cap to the container body containing the content liquid, and closing the cap and shaking the container sufficiently, the container can be kept upright even if the content liquid adheres to the radial liquid guide ribs on the top lid of the cap. By doing so, the attached content liquid quickly returns to the inside of the container main body from the top of the radial liquid guiding rib. Therefore, when opening the cap after shaking, the amount of the content liquid adhering to the upper lid can be reduced as much as possible.

  Further, when the cap is opened, the content liquid slightly adhered to the upper lid is held between the rib pieces forming the radial liquid guide ribs. Therefore, it is possible to prevent the liquid from dripping onto the outer wall of the cap when the cap is opened after shaking the container body.

  Furthermore, when the cap is closed again, the content liquid held between the rib pieces returns to the inside of the container body from the top of the radial liquid guiding rib. Therefore, it is possible to prevent dripping of the liquid on the outer wall of the container when the cap is closed.

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

  2 is a cross-sectional view of a state in which the cap 1A of one embodiment of the present invention is attached to the container body 30, FIG. 1 (a) is a partially cutaway perspective view of the upper lid 10A of the cap 1A, and FIG. It is the bottom view which looked at 10A of upper lids from the container main body side.

  The cap 1A is attached to the mouth portion 31 of a bottle-shaped container body 30 that contains a liquid material such as dressing, sauce, sauce, edible oil, and is screwed to the cap body 20 and the cap body 20. It consists of an upper lid 10A.

  The cap body 20 is formed of a resin such as polyethylene and is liquid-tightly attached to the mouth portion 31 of the container body 30. On the upper surface of the cap main body 20, a dispensing cylinder 21 protrudes, and an opening 22 is formed in a region surrounded by the dispensing cylinder 21. The dispensing cylinder 21 has a trumpet shape with an enlarged opening diameter at the tip, and a male thread ridge 23 that is screwed to the upper lid 10A is formed on the outer wall thereof.

  The upper lid 10A is formed of a resin such as polypropylene or polyethylene, and has an annular cylinder 11 inside the top surface. The annular cylinder 11 is liquid-tightly pressed against the inner wall of the upper end portion of the dispensing cylinder 21 in a state where the upper lid 10 </ b> A is screwed to the cap body 20.

  A radial liquid guiding rib 12 is formed in a region surrounded by the annular cylinder 11. The radial liquid guiding rib 12 has a shape in which a plurality of rib pieces 13 are arranged radially and the end of each rib piece 13 on the radial liquid guiding rib central part 12a side is continuous or close. As for each rib piece 13, the height of the rib piece 13 becomes high toward the radial liquid guide rib center part 12a from the peripheral part of the annular cylinder 11 side, and the top part 12b is formed in the center part of the radial liquid guide rib 12. FIG. . The top portion 12 b of the radial liquid guiding rib 12 hangs down inside the region surrounded by the extraction cylinder 21 in a state where the upper lid 10 </ b> A is attached to the cap body 20. The width of each rib piece 13 increases from the radial liquid guiding rib central portion 12a toward the peripheral portion on the annular tube 11 side. In this way, when the width of the rib piece 13 is increased from the radial liquid guiding rib central portion 12a toward the peripheral portion on the annular tube 11 side, when the upper lid 10A is attached and the container body 30 is shaken, the radial liquid It is possible to prevent the excessive content liquid from adhering to the surface of the guide rib 12, and to adhere to the rib piece 13 by narrowing the width of the rib piece 13 toward the radial liquid guide rib central portion 12 a side. The liquid can be collected and returned into the container body 30 when the content liquid is poured into the radial liquid guide rib central portion 12 a and returned into the container body 30. Furthermore, when the height of the rib piece 13 is increased toward the radial liquid guide rib central portion 12a side, it adheres to the radial liquid guide rib 12 when the container body 30 is upright after shaking. It is possible to quickly return the content liquid thus obtained from the top portion into the container body 30.

  Here, the width L1 of each rib piece 13 on the outer peripheral surface of the radial liquid rib 12 is 1.0 to 3.0 mm, the distance L2 between the rib pieces is 1.0 to 1.5 mm, and the height of the radial liquid rib 12 is high. L3 is preferably 5.0 to 10 mm.

  Between each rib piece 13, the liquid holding rib 15 is radially formed from the base part of the annular cylinder 11 toward the radial liquid guide rib central part 12a. In the present invention, the liquid holding rib 15 is provided as necessary to enhance the liquid holding property of the upper lid 10A. The liquid holding rib 15 is preferably formed so as to connect the base portion of the annular cylinder 11 and the radial liquid guide rib 12, and the gap 14 inside the annular cylinder 11 is preferably divided into a plurality of chambers. Thereby, the liquid retainability of 10 A of upper lids can be improved further.

  The width L4 of the end portion of the liquid holding rib 15 on the annular cylinder 11 side is preferably 1.0 to 1.5 mm, and the height L5 is preferably 2.0 to 3.0 mm.

  In the case where the liquid holding rib 15 is provided as described above, it is preferable to form the radial liquid guiding rib 12 with the gap 14 from the annular tube 11 as shown in the figure from the viewpoint of improving the liquid holding property of the upper lid 10A. . On the other hand, in the cap of the present invention, when the liquid holding rib 15 is not provided, the radial liquid guiding rib 12 is formed continuously from the base portion of the annular cylinder 11 without leaving the gap 14, or within the gap 14. It is preferable to form the gap 14 so narrow that the liquid does not flow from the viewpoint of improving the liquid retention of the upper lid 10A. When the liquid holding rib 15 is not provided, if the wide gap 14 is provided between the radial liquid guiding rib 12 and the annular cylinder 11 so that the liquid flows, the upper lid 10A is removed from the cap body 20 after the container body 30 is shaken. When removing, the content liquid adhering to the inside of the upper lid 10A flows through the gap 14 and gathers at one location of the base of the annular cylinder 11, and the collected liquid may be over the annular cylinder 11, which is not preferable.

  An annular wall 17 having a female thread ridge 16 that is screwed with the male thread ridge 23 of the cap body 20 is formed on the outer side of the annular cylinder 11 inside the top surface of the upper lid 10A. A wall 18 is formed.

  When the cap 1A is attached to a container body 30 containing a content liquid such as dressing, and the container body 30 is shaken with the upper cover 10A screwed to the cap body 20, the radial liquid guide rib 12 of the upper cover 10A is shaken. However, when the container main body 30 is erected, the content liquid quickly returns to the inside of the container main body 30 from the top portion 12b of the surface of the hanging radial liquid guiding rib 12. Therefore, when the upper lid 10A is removed from the cap body 20 after shaking, the amount of content liquid adhering to the upper lid 10A can be reduced as much as possible.

  Since the annular cylinder 11 is liquid-tightly pressed against the inner wall of the upper end of the dispensing cylinder 21 with the upper lid 10A screwed to the cap body 20, the content liquid is annular while the container body 30 is shaken. It does not adhere to the outside of the cylinder 11. Further, since the upper lid 10A is screwed onto the cap body 20, the upper lid 10A will not accidentally come off even if the container body 30 is vigorously shaken.

  After the shaking, when the upper lid 10A is removed, the content liquid is adhered to the inside of the annular cylinder 11 although it is a little. This content liquid is held between the rib pieces 13 forming the radial liquid guide ribs 12 or in the formation region of the liquid holding ribs 15. Therefore, it is possible to prevent dripping of the content liquid on the outer wall of the upper lid when the upper lid 10A is removed.

  Next, when the upper lid 10A is screwed and attached to the cap body 20 again, the content liquid held between the rib pieces 13 of the radial liquid guide ribs 12 or in the formation region of the liquid holding ribs 15 is removed from the radial liquid guide ribs 12. , Flows downward and returns from its top 12b into the container body 30A. Therefore, it is possible to prevent dripping of the content liquid on the outer wall of the container body when the upper lid 10A is mounted again.

  The cap of the present invention can take various forms. For example, in the cap 1B of FIG. 3, the top portion 12b of the radial liquid guiding rib 12 is brought into contact with the edge of the opening 22 opened on the upper surface of the cap body 20 with the upper lid 10B attached to the cap body 20. Is. Thus, when the top part 12b of the radial liquid guide rib 12 is brought into contact with the edge of the opening 22, the return of the content liquid adhering to the radial liquid guide rib 12 into the container body 30 can be further promoted. it can. In order to obtain the same effect, the top 12 b of the radial liquid guiding rib 12 may be sufficiently close to the edge of the opening 22.

  The cap 1C shown in FIG. 4 is the same as the cap 1A shown in FIG. 1 except that the opening 22 of the cap body 20 is closed with a cutout cover 25 with a pull-up 24, and the opening 22 is used when the user first uses the content liquid. Is to open.

  The cap of the present invention is useful as a cap for containers that contain liquid materials such as dressings, sauces, sauces, and edible oils.
