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 the container with the cap attached, and when opening the cap after shaking, The adhering content liquid is held by the lid so that when the cap is opened, the liquid content leaks to the outer wall of the cap, and when the cap is closed again, the liquid leaks to the outer wall of the container body. The purpose is to prevent the problem.

In order to achieve the above object, the present invention is a cap comprising a cap body attached to the mouth of the container body, and an upper lid screwed to the cap body,
The cap body has a dispensing cylinder protruding from the upper surface,
The upper lid has an annular cylinder that is pressed against the inner wall of the upper end of the dispensing cylinder in a state where the upper lid is mounted on the cap body, and a hemispherical or conical shape formed in a region surrounded by the annular cylinder. Provided is a cap having a protrusion and a radial rib connecting the base of the annular tube and the base of the protrusion between the annular tube and the protrusion.

  According to the cap of the present invention, since the protruding portion is formed in the region surrounded by the annular tube inside the top surface of the top lid, when the cap is attached to the container body and the container is erected, the top surface of the top lid The inner protrusion hangs down to the container body side. Moreover, this protrusion part is formed in a hemispherical shape or a cone shape, and has no ribs on the surface and is smooth. 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 erected even if the content liquid adheres to the protruding part of the top lid of the cap Thus, the content liquid adhering to the projecting portion flows downwardly on the surface of the projecting portion and quickly returns into the container body. 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.

  Moreover, since the radial rib which connects the base part of a cyclic | annular pipe | tube, and the base part of a protrusion part is formed between the cyclic | annular pipe | tube of a top cover, and a protrusion part, when opening a cap, it adheres slightly to a top cover. The content liquid is held between the radial 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.

  Further, when the cap is closed again, the content liquid held by the radial ribs travels down the surface of the protrusion, flows downward, and returns into the container body. 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 extraction cylinder 21 as an inner ring in a state where the upper lid 10A is screwed and attached to the cap body 20. The annular cylinder 11 may be formed of, for example, an elastic member attached to the inner wall of the upper lid, regardless of the cross-sectional shape or material, as long as it is liquid-tightly pressed against the inner wall of the upper end portion of the dispensing cylinder 21 as an inner ring. The cross section formed integrally with the upper lid 10A may be a substantially triangular protrusion. In a region surrounded by the annular cylinder 11, a smooth hemispherical protrusion 12 having no ribs formed on the surface is formed at a distance from the annular cylinder 11. The protruding portion 12 hangs down inside the region surrounded by the extraction cylinder 21 in a state where the upper lid 10A is mounted on the cap body 20.

  A radial rib 13 is formed between the annular cylinder 11 and the protrusion 12 to connect the base of the annular cylinder 11 and the base of the protrusion 12. From the standpoint of liquid retention, the height of each rib 13a constituting the radial rib 13 is 1.0 to 3.0 mm, the width L1 of the rib 13a is 1.0 to 1.5 mm, and the maximum distance L2 between the ribs 13a. Is preferably 5.0 to 10 mm. Moreover, the ratio of the formation area of the radial rib 13 and the formation area of the protrusion 12 is maintained in the formation area of the radial rib 13 after shaking the container body 30 if the formation area of the radial rib 13 is excessively wide. The amount of the content liquid increases, and a large amount of the content liquid is held in the upper lid 10A. On the other hand, if it is too narrow, the amount of the content liquid held in the radial rib 13 formation region decreases, and the upper lid When 10A is removed from the cap body 20, it becomes difficult to hold the content liquid adhering to the inside of the top surface of the upper lid 10A with the radial ribs 13. Therefore, the ratio between the length L3 of the radial rib 13 and the radius L4 of the bottom surface of the protrusion 12 is preferably set to 1.0: 5.0 to 1.0: 1.5.

  In this embodiment, a horizontal plane is provided between the base of the annular tube and the base of the protruding portion so that the annular tube and the protruding portion are spaced apart from each other. It can also be connected directly to the proximal end. In this case, each rib has a triangular plate shape.

  The annular cylinder 11, the projecting portion 12 and the radial rib 13 are preferably molded integrally with the upper lid 10A, but these may be molded separately from the upper lid 10A and bonded or fitted. good.

  An annular wall 15 having a female thread ridge 14 that is screwed with a male thread ridge 23 of the cap body 20 is formed on the outer side of the annular cylinder 11 on the top surface inside of the upper lid 10A, and further on the outside thereof A wall 16 is formed.

  When the cap 1A is attached to the container main body 30 containing the content liquid such as dressing and the upper lid 10A is screwed and attached to the cap main body 20, the container main body 30 is shaken and the content liquid is applied to the protruding portion 12 of the upper lid 10A. However, when the container body 30 is erected, the content liquid flows downward on the smooth surface of the projecting portion 12 that hangs down and quickly returns into the container body 30. 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 portion of the dispensing cylinder 21 in a state where the upper lid 10A is screwed to the cap body 20, the content liquid is annularly formed by shaking the container body 30. 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.

  When the upper lid 10A is removed after shaking, the content liquid is slightly attached to the inside of the annular cylinder 11, but this content liquid is a radial rib provided between the annular cylinder 11 and the protruding portion 12. Is held in the formation area. 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 10 </ b> A is screwed into the cap body 20 again, the content liquid held in the area where the radial ribs 13 are formed flows downward along the surface of the protruding portion 12 and returns into the container body 30. 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, the cap 1B of FIG. 4 provided with the upper lid 10B of FIG. 3 is provided with a conical projection 12 instead of the hemispherical projection 12 of the cap 1A described above, and the upper lid 10C of FIG. A cap 1C of FIG. 6 provided with a pyramid-shaped protrusion 12 is provided instead of the hemispherical protrusion 12 of the cap 1A.

  When the cone-shaped projecting portion 12 is provided in this manner, the content liquid adhering to the projecting portion 12 returns to the container body 30 more quickly by raising the container body 30 upright.

  The cap 1D of FIG. 8 provided with the upper lid 10D of FIG. 7 is provided with a dripping guide protrusion 17 on the top of the hemispherical protrusion 12 of the cap 1A. When the dripping guide protrusion 17 is provided, the content liquid adhering to the surface of the projecting portion 12 is concentrated on the dripping guide projection 17 through the surface of the projecting portion 12 by erecting the container body 30. Can be further promoted to return to the container body 30.

  The cap 1E of FIG. 10 having the upper lid 10E of FIG. 9 is in a state where the top lid 10E is mounted on the cap body 20 when the dripping guide protrusion 17 is provided on the top of the hemispherical projection 12 of the cap 1A. The tip of the dripping guide protrusion 17 is brought into contact with the edge of the opening 22 opened on the upper surface of the cap body 20. Thus, when the dripping guide protrusion 17 is brought into contact with the edge of the opening 22, the return of the content liquid adhering to the protrusion 12 into the container body 30 can be further promoted.

  In the cap of the present invention, the outer side of the upper lid can take various shapes. For example, the upper outer side of the upper lid is recessed according to the formation of the protruding portion 12 as in the caps 1A to 1D described above. Alternatively, the upper surface outside of the upper lid 10E may be formed flat like the cap 1E of FIG.

  The cap 1F shown in FIG. 11 is the same as the cap 1D shown in FIG. 8 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 liquid content. Is to open. Such a cutting lid 25 may be provided in the cap body 20 of the caps 1A to 1C without the dripping guide protrusion 17.

  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.
