JP 2009-029475 A

  In the prior art described in this Patent Document 1, it is possible to surely prevent “clogging” of the outlet 107, but the insertion piece 116 does not seal the outlet 107. The contents leaked between the cap main body 102 and the lid body 110 in the closed posture state, and the leaked contents leaked not only when the swinging cap 100 was soiled but also when the lid body 110 was in the open posture. There was a problem that the contents contaminated the surroundings.

  Therefore, the present invention was devised to solve the above-mentioned problems in the prior art, and it is a technical problem to seal the outlet with a lid, and thus provides an outlet cap that does not cause contamination due to the contents. It is intended.

The main structure of the means of the present invention for solving the above problems is as follows.
The cap body is tightly assembled to the mouth tube portion of the container main body containing the contents, and the top opening is provided on the top plate with a swing-out opening for dispensing the contents. A lid having a functional part that seals the outlet of the cap body in the closed posture state;
The cap outlet of the cap body is configured with a through hole formed through the top plate and an opening tapered surface that expands upward from the through hole,
The functional part that seals the outlet is composed of an insertion piece that enters the through-hole and a seal cylinder piece that surrounds the insertion piece and closes the lower end edge to the opening taper surface of the outlet. about,
It is in.

  When the swinging cap is in the closed position, the insertion piece of the functional part that seals the lid enters the through hole of the swinging outlet of the cap body, so the contents try to adhere to the hole surface of the through hole due to moisture or the like. However, the contents to be adhered and solidified are pushed out and removed by the inserted piece that enters each time the lid is opened and closed.

  In the closed posture of the swinging cap, the sealing cylinder piece of the functional part that seals the lid closes the lower end edge of the cap taper on the tapered opening surface of the swinging outlet. The through hole of the mouth is in a sealed state. Since the seal cylinder piece is in close contact with the opening tapered surface from the upper side of the seal cylinder piece with respect to the inclined surface of the opening taper surface, the seal cylinder piece is brought into an appropriate close contact state by elastic deformation without excessive force. Become.

  Another configuration of the present invention is obtained by adding the insertion piece of the functional unit to be sealed and the seal cylinder piece in the shape of a cylindrical piece and arranging them coaxially in addition to the main configuration described above.

  In the case where the insertion piece and the seal cylinder piece of the functional part to be sealed are configured in a cylindrical piece shape and arranged coaxially, it is possible to obtain resource saving of the molding material by making the insertion piece hollow. It is also possible to easily obtain a configuration of a sealing cylinder piece that is easily in close contact with the opening tapered surface.

  In addition, another configuration of the present invention is obtained by adding a plurality of combinations of a swing port and a functional unit that seals the swing port to the main configuration described above.

  If there are multiple combinations of the outlet and the functional part that seals the outlet, multiple outlets will be placed in a dispersed state, so the contents can be expanded over a wide range. Can be spread almost evenly.

  In addition, another configuration of the present invention is obtained by adding a lid body to the cap body so as to be pivotable and openable by a hinge to the main configuration described above.

  When the lid is connected to the cap body by a hinge so that it can be rotated and opened, the coupling position of the lid with respect to the cap body is constant, so the combination of the outlet and the functional part to be sealed is constant. As a result, the sealing seal of the swing-out port by the functional unit that seals is stably achieved. In particular, when a plurality of combinations of the outlet and the functional part to be sealed are provided, each outlet and the functional part to be sealed can be stably opposed to each other in a one-to-one relationship.

  Further, another configuration of the present invention is that the cap main body positioned on the opposite side of the hinge is added to the main configuration described above in which a cap is coupled to the cap main body so that the lid can be rotated and opened. In addition to the upper end portion and the end portion of the lid body, which is also located on the opposite side of the hinge, a locking function portion that holds the closed posture of the lid body by overcoming locking is added.

  For those provided with a locking function part that holds the lid closed position by getting over and locked, the lid body is pressed against the cap body in a closed position with a constant force. Thus, the sealing cylinder piece of the functional part to be hermetically sealed has its lower end edge closely contacted with the opening tapered surface of the swing-out opening.

Since the present invention has the above-described configuration, the following effects can be obtained.
In the main configuration of the swing cap according to the present invention, the contents to be adhered and solidified in the through hole of the swing outlet are reliably removed by the extruded piece of the functional part to be sealed. Thus, the content can be stably and reliably shaken out without being blocked.

  In addition, the outlet of the cap body is properly sealed by the sealing cylinder piece of the functional part sealed by the lid, and the contents leak even if the container falls over while the contents are stored. The contents can be stably stored and held without coming out.

  In the case where the insertion piece and the seal cylinder piece of the functional part to be sealed are configured in a cylindrical piece shape and arranged coaxially, this kind of swing-out cap can be obtained inexpensively and easily.

  If there are multiple combinations of the outlet and the functional part that seals the outlet, multiple outlets will be placed in a dispersed state, so the contents can be expanded over a wide range. Can be sprayed substantially evenly, whereby a substantially constant amount of contents can be efficiently sprinkled over a wide range.

  In the case where the lid is connected to the cap body by a hinge so as to be able to be opened and closed by rotation, the swinging opening and the functional part to be sealed can be reliably opposed in a one-to-one relationship. A stable sealing operation of the outlet can be obtained.

  For those provided with a locking function part that holds the closed position of the lid by overcoming locking, the swinging outlet by the sealing cylinder piece of the function part to be sealed is strong and reliable by the pressing force of the locking function part. A good seal can be achieved and maintained.

FIG. 2 is an enlarged vertical cross-sectional view of a main part of a combination of a swing opening and a functional unit to be sealed in the embodiment example shown in FIG. 1. FIG. 2 is an overall plan view of the exemplary embodiment shown in FIG. 1 in an open posture state. It is a whole longitudinal side view of a closed posture state for explanation of a prior art.

Embodiments of the present invention will be described below with reference to FIGS.
In this embodiment, in the closed posture state shown in FIG. 1, the side where the lid body 10 is positioned with respect to the cap body 2 is the upper side, and the opposite side (the lower side in FIG. 1) is the lower side. Further, the side where the hinge 18 is located is the rear, and the opposite side (the left side in FIG. 1) is the front.

  As shown in FIG. 1, the swing-out cap 1 is attached to a container main body 19 that contains powdered or granular contents, and is a cap main body 2 that is closely assembled to the mouth tube portion 20 of the container main body 19. And a lid 10 that opens and closes the swing opening 7 provided in the cap body 2, and is formed of a flexible synthetic resin such as polypropylene, for example.

  The cap body 2 has a top cylindrical shape in which a top plate 4 is connected to the upper end of an assembled tube 3 that is externally fitted to the mouth tube portion 20 of the container body 19 and screwed together. In the case of the embodiment, four outlets 7 are opened (see FIG. 3). A fitting step portion 5 is formed so as to rise from the assembly tube 3 side at a portion connected to the assembly tube 3 which is a peripheral end portion of the top plate 4. Is formed with a locking recess 6 of the locking function part K that holds the closed position of the lid 10 with respect to the cap body 2.

  A swing opening 7 (see FIG. 2) provided in the top plate 4 of the cap body 2 has a round hole-like through hole 8 that penetrates the top plate 4 up and down, and a conical surface that expands upward from the through hole 8. It is comprised with the opening taper surface 9 comprised with a taper surface. The through hole 8 of the outlet 7 is set to have a diameter suitable for the outlet of the contents accommodated in the container body 19. Moreover, the inclination taper angle of the opening taper surface 9 of the outlet 7 is not particularly specified, but considering the relationship with the seal cylinder piece 17 of the functional part 15 to be sealed, a range of about 10 ° to 50 °. Seems to be suitable.

  The lid body 10 is a thin, dished, top-like short cylindrical shape in which a flat top wall 14 is connected to the upper end of a short cylindrical piece-like peripheral wall 11 that is externally fitted to the fitting step portion 5 of the cap body 2. A finger-hanging piece 13 protrudes from the lower end of the outer peripheral surface on the front side of the peripheral wall 11, and the engagement concave portion of the cap body 2 is formed on the inner peripheral surface portion of the peripheral wall 11 portion provided with the finger-holding piece 13. 6 is provided with a locking protrusion 12 that forms a locking function portion K that holds the lid 10 in a closed position. The lower end of the outer peripheral surface on the rear side of the peripheral wall 11 is connected to the upper end of the outer peripheral surface on the rear side of the assembled cylinder 3 of the cap body 2 by a hinge 18. The hinge 18 preferably exhibits a function of self-holding its posture by reversing a snap hinge or the like. Further, on the lower surface of the top wall 14 of the lid body 10, the same number of sealing function portions 15 (see FIG. 3) as the swing-out ports 7 are opposed to the swing-out ports 7 in a closed posture from the upper side in a hanging manner. Is provided.

  The sealing functional unit 15 (see FIG. 2) provided in the lid body 10 includes an insertion piece 16 (in the case of the illustrated embodiment, a through hole) that enters the through hole 8 of the swing-out port 7 when the lid body 10 is in the closed posture. 8) and a seal cylinder piece 17 for bringing the lower end edge of the opening tapered surface 9 of the outlet 7 into close contact with each other. Both the insertion piece 16 and the seal cylinder piece 17 are formed in a cylindrical shape and are arranged coaxially. The insertion piece 16 has a cylindrical shape. By making the insertion piece 16 into a hollow cylindrical shape, the amount of the synthetic resin material consumed can be reduced without reducing the push-out action of the insertion piece 16 against the attached contents. Because. The seal cylinder piece 17 is a main part that achieves and maintains the seal of the outlet 7, and the lower end edge is easily elastically deformed over the entire circumference so that the opening taper surface 9 is easily elastically contacted. Slightly thin.

Next, the operation of the swing cap 1 will be described.
The contents are ejected from the container body 19 equipped with the swing cap 1 by hooking the fingertip onto the finger hook 13 of the lid 10 and locking the locking function portion K including the locking recess 6 and the locking protrusion 12. Against the force, the lid body 10 is forcibly rotated and opened, and the outlet 7 is opened. With the lid 10 in the open posture, the container body 19 is turned upside down to sprinkle the contents. When the dispensing of the contents is finished, the container body 19 is returned to the upright state, the lid body 10 is turned to the closed position, and the locking recess 6 and the locking protrusion 12 are moved over and locked. Then, the lid body 10 is set in a closed posture and put in a storage state. At this time, even if a part of the content adheres to the through hole 8 due to moisture, the attached content is pushed out and removed by the insertion of the insertion piece 16 into the through hole 8. Will not cause “clogging”.

  When the container main body 19 with the swing cap 1 attached is stored, the swing opening 7 which is the only opening of the container main body 19 is securely and firmly sealed by the sealing functional portion 15. There is no risk of moisture entering from the outside, and the contents can be stored and held safely. At this time, the sealing cylinder piece 17 of the functioning part 15 that seals the through hole 8 of the swing-out port 7 is caused by the locking force of the locking function part K composed of the locking recess 6 and the locking protrusion 12. The lid 10 is pressed against the opening taper surface 9 by the closed posture holding force of the lid 10. For this reason, the lower end edge part of the seal cylinder piece 17 will be closely elastically contacted with the opening taper surface 9 over the entire circumference, and thereby the sealed state of the container body 19 is stably and firmly maintained. At the same time, the contents are surely prevented from leaking from the outlet 7 during storage.

  As described above, the configuration and the operation effect of the present invention have been described according to the embodiment. However, the embodiment of the present invention is not limited to the above embodiment. For example, it is also possible to adopt a configuration in which a combination of one ejection port 7 and the functional unit 15 to be sealed is positioned at the center of the ejection cap 1 and the lid 10 is attached to and detached from the cap body 2 by screwing. It is.

  The swing cap according to the present invention can reliably prevent the contents from adhering to the swing opening established in the cap body, and can stably achieve and maintain the seal of the swing opening stably. Application in the field may be possible.
