Description

  The present invention relates to a synthetic resin hinge cap attached to the mouth of a container made of glass or synthetic resin, and more specifically, attached to the vicinity of the upper peripheral edge of the top wall of the cap when the lid is closed. The present invention relates to a hinge cap that does not cause liquid splash of the liquid deposit.

  Conventionally, a hinge cap for pouring liquid is used by tilting the container when removing the top lid and pouring the liquid of the contents, so that the liquid adheres to the vicinity of the top surface of the top wall of the cap body and the liquid is attached. When the upper surface of the top wall where the kimono remains is in close contact with the lower surface of the side wall of the upper lid when the lid is closed, the liquid deposit may be scattered and scattered with the force of closing the upper lid, contaminating the user's clothes and other peripheral parts. was there.

  Various hinge caps have been proposed to solve the above problems. For example, in Japanese Utility Model Laid-Open No. 05-035705, a scattering prevention cover plate is suspended from the lower end of the skirt wall of the upper lid so as to cover the upper outer surface of the cap body (Patent Document 1), or Japanese Patent Laid-Open No. 08-1551067. Describes a cap in which the periphery of the top wall of the cap body is formed on an inclined surface and the scattering direction is controlled (Patent Document 2).

  Further, in Japanese Patent Application Laid-Open No. 08-198297, an uneven portion is provided on each of the cap body and the upper lid, and both are brought into contact with each other, thereby holding the upper lid and the cap body in a non-contact state (Patent Document 3). In Japanese Utility Model Laid-Open No. 04-91856, a projecting portion is formed on either the lower surface of the upper lid or the upper surface of the cap body, and both face each other through the projecting portion when the lid is closed (Patent Document 4). A hinge cap that prevents liquid splashing has been proposed.

  However, the conventional example described above has the following problems. In the cap described in Patent Document 1, since the cover plate for preventing scattering protrudes outward, a step with the cap body is generated. There is also a problem above. Moreover, since the cover plate is thin, there is still a problem in the ease of operation when opening the lid. Further, in the cap described in Patent Document 2, a step is generated between the inclined portion formed on the peripheral edge of the top surface wall of the cap body and the side wall of the cap body. Yes. Moreover, although the liquid scattering direction can be controlled by the inclined portion, it is difficult to completely prevent the liquid scattering.

  Furthermore, in the invention described in Patent Document 3, at least a half-circumferential portion on the side opposite to the hinge connecting portion is in a non-contact state with the cap body, and the dripping from the spout falls on the inner surface of the skirt wall, and the cap body Although the liquid adhering to the peripheral edge of the top surface of the wall does not scatter, the gap formed between the cap body and the top cover is not preferable for hygiene and the user does not completely close the cover. May give. Further, in the invention described in Patent Document 4, a protrusion is formed on at least one of the upper surface of the cap body or the lower surface of the upper lid, and the conventional cap in which the contact area by the protrusion has no protrusion. This is only a small amount (about 1/4 in the described embodiment), and even if the liquid splash is reduced to some extent, it cannot be completely prevented. Furthermore, since the contact load force concentrates on the tip of the protruding portion, the tip or the like may be deformed due to repeated use or impact during stoppering.

  The present invention was made in order to solve the problems in the hinge cap made of synthetic resin as described above, has excellent appearance characteristics, no sanitary problems, and further effectively prevents liquid splashing and is repeated. An object of the present invention is to provide a hinge cap that can withstand the impact at the time of use and capping.

  The present invention relates to a hinge cap including a cap body and an upper lid connected to the cap body by a hinge, and a liquid splash prevention circumferential shape that abuts the lower surface of the upper lid side wall when the lid is closed on the upper peripheral edge of the top wall of the cap body. In addition to forming a wall, at least one of the upper surface of the top wall of the cap main body and the lower surface of the side wall of the upper lid facing each other is formed with a protruding support portion that contacts the other surface when the lid is closed.

  In the present invention, the liquid splash prevention circumferential wall formed on the top surface of the top surface of the cap body is formed over the entire circumference excluding the hinge connecting portion of the top surface wall periphery of the cap body, and the top surface portion is pointed or pointed. It is desirable to form it as thin as possible. This is because the thinner the abutting portion is, the more effective the effect of preventing liquid splashing when the lid is closed.

  The hinge cap of the present invention is provided with a liquid splash prevention peripheral wall whose top surface is pointed or thin at the peripheral edge of the top surface of the top surface of the cap body, and reduces the contact area that comes into contact with the lower surface of the side wall of the top lid when the lid is closed. This prevents the liquid residue remaining on the top surface of the top wall from scattering. A projecting support portion that protrudes downward or upward is provided at an appropriate location on at least one of the upper surface of the top wall of the cap body and the lower surface of the side wall of the upper lid so as to contact the other surface when the lid is closed. Therefore, when the lid is closed, a contact load against the upper surface of the upper lid side wall can be received by the protrusion-like support portion at the time of closing the lid, so that deformation of the liquid splash preventing circumferential wall due to repeated use can be prevented. This prevents deformation due to the load at the time of plugging, and always ensures the sealing performance of the hinge cap when the lid is closed. Further, by receiving the contact load with the projecting support portion, the top surface of the liquid splash preventing circumferential wall can be made thinner, and the liquid splash preventing effect is enhanced.

  The number and position of the projecting support portions are arbitrary, and the shape may be any shape that can maintain rigidity capable of preventing deformation of the peripheral wall of the liquid splash prevention when the lid is closed. For example, the contact surface is spherical. Such hemispherical projections are suitable. Moreover, it is preferable that the liquid splash prevention circumferential wall formed in the peripheral part of the top wall of the cap body is formed in the vertical direction continuously in the peripheral direction of the peripheral part of the side wall of the cap body. In addition, the cross-sectional shape can be any shape such as a triangular shape, a rectangular shape, or a trapezoidal shape, but in any case, the top surface portion that contacts the lower surface of the side wall of the upper lid has a pointed shape or a thin shape with a small contact area. It is desirable to be.

In the hinge cap of the present invention, due to the presence of the liquid splash prevention circumferential wall provided at the peripheral edge of the top surface of the top wall of the cap body, the hinge lower surface and the top surface of the top surface of the cap body are rotated by the hinge when closed. Since the liquid does not collide directly, it is possible to prevent the liquid remaining on the top surface of the top surface from splashing outside when the liquid content is poured out.
Furthermore, the presence of the protruding support provided on the upper surface of the top wall of the cap body or the lower surface of the side wall of the upper lid appropriately eliminates or relaxes the load applied to the peripheral wall of the liquid splash prevention when the cover is closed. Since the deformation of the wall-like wall is prevented, the liquid splash-preventing effect remains effective even after repeated use. It will not be damaged. Similarly, there is no problem of deformation with respect to impact load at the time of plugging.
In addition, in the hinge cap of the present invention, the annular liquid splash preventing circumferential wall is formed in an annular shape so as to extend vertically upward continuously from the side wall of the cap body, and its tip end abuts on the lower surface of the upper lid. When closing the lid, there is no gap between the cap body and the top lid, effectively preventing liquid splashing to the outside as well as preventing foreign objects from entering and remaining on the periphery of the top wall It is possible to provide a cap that is excellent in terms of hygiene without dust or the like from the outside adhering to the contents and excellent in appearance since no step is formed between the contents and the upper lid.

  The best mode for carrying out the present invention will be described below with reference to FIGS.

  1 to 3 show an embodiment of the present invention. In this embodiment, the hinge cap 1 has a cap body 2 and an upper lid 3 as main components, and is plugged into a mouth portion of a container (not shown). The cap body 2 and the upper lid 3 are connected by a hinge 4 therebetween. The cap body 2 has a pouring cylinder 5, an inner cylinder 6 and an outer cylinder 7, and is plugged and mounted along a constricted recess 8 formed on the outer periphery of the container mouth.

  Further, the cap body 2 is provided with a top wall 9 so as to cover the opening surface of the container mouth, and the top wall 9 is formed with an opening for pouring the contents from the dispensing tube 5. And a pull ring 10 is additionally provided. In addition, a liquid splash preventing circumferential wall 12 is formed in an annular shape at the upper peripheral edge 11 of the top wall 9. The liquid splash preventing circumferential wall 12 extends above the side wall of the outer cylinder 7 of the cap body 2 and is formed in an annular shape over substantially the entire circumference excluding the hinge connecting portion of the cap body 2. The top surface portion 13 of the liquid splash preventing circumferential wall 12 is formed so as to abut on the side wall lower surface 14 of the upper lid 3 when the lid is closed. In this embodiment, the shape of the liquid splash preventing circumferential wall 12 is triangular as shown in FIG. 5a, and the shape of the top surface portion 13 contacting the side wall lower surface 14 is pointed. As shown in FIG. 5c, other shapes may be used as long as the top surface portion can be formed thin, such as a trapezoidal shape or a rectangular shape.

  Further, a projecting support portion 15 is formed on the lower surface 14 of the side wall of the upper lid 3 to prevent deformation when the liquid splash preventing circumferential wall 12 provided at the peripheral edge of the top wall is closed. The protruding support portions 15 are arranged at equal intervals on a part of the lower surface 14 of the side wall of the upper lid 3 on the side of the flange portion 16 opposite to the hinge 4. The projecting support portion 15 is formed so as to be in contact with the upper surface of the top wall 9 in a downward direction on the inner side of the liquid splash preventing circumferential wall 12 when the lid is closed. Since it is preferable to prevent the inside of the cap from being contaminated by liquid splashing inward of the cap when the lid is closed, in this embodiment, the protrusion-like supporting portion is used to reduce the contact area. The tip 15 has a spherical convex surface and is formed at equal intervals on a part of the lower surface 14 of the side wall of the upper lid 3. However, as shown in FIGS. 4a to 4c, other shapes such as an ellipse may be used. The number is also appropriately selected.

  In the present embodiment, the hinge cap 1 configured as described above is used by being plugged into the mouth of the container. The consumer lifts the collar portion 16 formed on the upper lid 3 in use, opens the upper lid 3 by rotating the hinge, tears the breaking groove provided on the top wall 9 by pulling the pull ring 10, A spout is formed, and the container is tilted to pour out the desired liquid content from the spout cylinder 5. Then, after pouring, the upper lid 3 is rotated to the cap body 2 side to close the lid. In order to close the lid, the container tilted before the lid is closed is returned to the vertical direction. At this time, the contents that have not been completely released out of the container may remain on the upper peripheral edge 11 of the top wall 9. is there. When the upper lid 3 is closed, the lower side wall 14 of the upper lid 3 and the top wall upper surface peripheral edge portion 11 of the cap body 2 come into contact with each other, but in this embodiment, the liquid splash preventing circumferential wall 12 and the protruding support portion 15 are in contact with each other. As compared with the case of direct contact, the contact surfaces of each other become smaller, and the remaining contents adhering to the upper peripheral edge 11 of the top wall 9 are scattered outwardly with the moment of closing. Can be prevented.

  As shown in FIG. 3, when the lid is closed, the lower surface 14 of the side wall 14 of the upper lid 3 and the upper surface of the cap body 2 are in contact with each other at two locations in the radial direction by the peripheral wall 12 and the projecting support portion 15. Therefore, the heights of the liquid splash preventing circumferential wall 12 and the protruding support portion 15 need to be the same height or substantially the same height. In this case, it is necessary to apply a load to the protruding support portion 15. Further, since the projecting support portion 15 abuts against the opposing surface, the liquid splash prevention circumferential wall is sufficiently supported by the projecting support portion 15, so that even when the lid is repeatedly closed, even the liquid splash prevention is performed. Even if the vicinity of the top surface portion of the peripheral wall 12 is formed in a pointed shape or an extremely thin shape, the deformation of this portion is sufficiently prevented, and the distortion and deformation of the cap can also be effectively prevented. Similarly, it is possible to provide sufficient load resistance against these deformations due to impact load when the cap is plugged into the container. Thereby, the liquid splash prevention of the liquid splash prevention peripheral wall 12 can be maintained effectively.

  The size and shape of the liquid splash preventing circumferential wall 12 and the protruding support portion 15 are appropriately selected as necessary, but the effect of preventing the liquid splash is enhanced when the respective contact areas are smaller. Needless to say, it is preferable that the protrusion-shaped support portion 15 is formed into a shape that is loaded.

  Further, as shown in FIG. 1, by providing the load-bearing rib 18 on the inner side of the side wall 17 of the upper lid 3, it is possible to further improve the effect of preventing the cap from being deformed by an impact when the stopper is attached. The load-bearing rib 18 is particularly effective when used for a heat-resistant cap having a high stoppering attachment force. In this case, the outer cylinder should be thick.
