Description

  The present invention relates to a hinge cap, and more particularly to a hinge cap provided with a liquid splash prevention plate.

  Conventionally, when tilting and pouring a container with a hinge cap, the content liquid may adhere to the upper part of the side wall of the cap body. If the cap is closed with the content liquid attached, the content liquid (adhered liquid) adhering to the impact at that time may scatter outward, which may contaminate the user's clothes, etc. It was necessary to close the lid slowly. In order to solve such a problem, a device has been devised in which a liquid splash prevention plate such as a cover plate (see Patent Document 1) for preventing scattering is provided on the upper lid.

Utility Model Registration No. 2583036

  However, in the conventional technology, there is a gap between the liquid splash prevention plate provided on the upper lid in the closed state and the outer peripheral surface of the cap body, and therefore, when the lid is closed, the adhesion liquid is prevented from splashing against the inner surface of the plate. Although it was possible, there was a problem that the adhering liquid drooped to the lower part of the side wall of the main body due to its own weight. Moreover, the prevention of scattering of the adhering liquid is not perfect, and there is a possibility that the adhering liquid may be scattered in a downward direction that is not covered by the plate when the lid is closed.

  Therefore, an object of the present invention is to improve a cap provided with a liquid splash prevention plate and to provide a hinge cap that does not cause such a problem.

  The present invention relates to a hinge cap in which a cap main body and an upper lid are coupled by a hinge, and a liquid splash prevention plate is provided in a region opposite to the hinge of the skirt portion in the upper lid. The hinge cap is characterized in that a liquid stop projection is formed that contacts the side wall of the cap body when the lid is closed. Desirably, the said liquid stop protrusion part is provided over the circumferential direction full length of the said liquid splash prevention board.

  Further, the present invention is the hinge cap characterized in that a recess is provided in the outer peripheral surface of the side wall of the cap body, and the liquid splash prevention plate is accommodated in the recess when the lid is closed.

  The present invention is also the hinge cap characterized in that a groove is provided on the top surface of the side wall of the cap body.

  The present invention is the hinge cap characterized in that the groove portion communicates with the liquid discharge hole.

  In the present invention, the liquid sticking projection is formed on the inner peripheral surface of the liquid splash preventing plate so as to come into contact with the main body side wall of the cap body when the lid is closed. Even when the liquid splash prevention plate is scattered, the splash prevention can be prevented in the range where the liquid splash prevention plate is formed, and when the liquid stop projection is closed, the lower end surface of the side wall of the upper lid comes into contact with the top surface of the side wall of the cap body. At the same time, since it comes into contact with the side wall of the cap main body, it is possible to prevent the adhered liquid from scattering downward. Further, the content liquid colliding with the inner peripheral surface of the liquid splash preventing plate is held between the inner peripheral surface of the liquid splash preventing plate, the liquid stop protrusion, and the side wall of the cap body, and can be prevented from flowing downward. In particular, a higher effect can be obtained by forming the liquid stop projection part over the entire circumferential direction of the liquid splash prevention plate.

  In addition, a recess is formed on the outer peripheral surface of the side wall of the cap body, and the liquid splash prevention plate is accommodated in the recess when the lid is closed. The liquid storage space that accumulates can be reduced. That is, it is possible to reduce the amount of adhering liquid that scatters in advance. In addition, the liquid splash prevention plate is accommodated in the recess when the lid is closed, so that a cap having excellent appearance can be provided.

  Also, since the groove portion is provided, the liquid stop projection rises while rubbing the main body side wall when the liquid content accumulated between the liquid splash prevention plate and the main body side wall of the cap body is opened again when the cover is closed. To do. Therefore, the liquid stop projection works like a wiper and the content liquid is lifted up and guided to the groove, so that it can be prevented from drooping to the lower part of the main body side wall.

  Further, since the groove portion communicates with the liquid discharge hole, the adhesion liquid guided to the groove portion can flow out.

  An embodiment of the present invention will be described with reference to FIGS. The hinge cap 1 is made of a synthetic resin, and includes a cap body 2, an upper lid 3 attached to the cap body 2, and a hinge portion 4 that connects the two 2 and 3 together.

  The cap body 2 includes a pour tube 5 having a radial tip and a tube portion 7 connected to the pour tube 5 via a top wall 6. The top wall 6 inside the dispensing cylinder 5 is provided with a blocking wall 8 that blocks the flow of fluid. The blocking wall 8 is provided with an endless crack 9 and a pull ring 10, 10 is disposed inside the fissure 9. In the present embodiment, the blocking wall 8 is provided in a substantially triangular shape.

  The top wall 6 is provided with a locking cylinder 11 concentric with the dispensing cylinder 5. The locking cylinder 11 has a larger diameter than the dispensing cylinder 5.

  A recess 12 a is formed at a location where the liquid is likely to adhere, and the recess 12 a has a shape in which the upper outer peripheral surface of the side wall 12 is cut out. In addition, the body side wall 12 is provided with a finger hooking portion 12b that is continuous with the recess 12a at a location opposite to the hinge 4. The main body side wall 12 is provided with a groove 13 formed in the axial direction on the top surface 12c. However, in the present embodiment, the portion of the finger hook portion 12b is thick, and therefore the groove portion 13 is not formed in the portion of the finger hook portion 12b. Therefore, the groove portion 13 is provided so as to be divided into both sides by the finger hook portion 12b. A liquid discharge hole 14 is provided on the bottom surface of the groove portion 13. Therefore, the groove 13 communicates with the back side of the cap body 2 through the liquid discharge hole 14.

  The upper lid 3 includes a ceiling wall 15 and a skirt portion 16 continuous with the ceiling wall 15, and a flange portion 17 is provided at a lower end portion opposite to the hinge portion 4. On the inner surface of the top wall 15, an outer ring 18 formed so as to seal the tip of the dispensing tube 5 from the outer peripheral side when the lid is closed and the inner side of the outer ring 18 are disposed. An inner ring 19 for sealing is provided concentrically.

  A liquid splash prevention plate 20 is provided in a region of the upper lid 3 of the skirt portion 16 on the side of the collar portion 17 of the median line M (a region opposite to the hinge portion 4). The liquid splash prevention plate 20 is provided in a substantially arc shape in plan view in accordance with the shape of the recess 12a provided by cutting out the side wall 12 of the cap body 2, and is stored in the recess 12a when the hinge cap 1 is closed. .

  On the inner peripheral surface of the liquid splash prevention plate 20, a liquid stop projection 20a is provided. The liquid stop projection 20a is provided in a substantially straight line shape in plan view over the entire length along the circumferential direction of the inner peripheral surface, and comes into contact with the outer peripheral surface of the recess 12a of the main body side wall 12 when the hinge cap 1 is closed. In addition, the length of the liquid stop protrusion part 20a can be suitably changed as needed.

  The hinge cap 1 of the present invention has a structure with less liquid accumulation because the recess 12a of the body side wall 12 is notched, and the cap body 2 is more likely to scatter than the conventional hinge cap. The amount of the attached content liquid (attached liquid) is reduced in advance. When the upper lid 3 is closed, the adhering liquid is received by the liquid splash preventing plate 20, so that the adhering liquid does not scatter.

  Further, since the liquid stop projection 20 a is provided over the entire circumferential direction of the liquid splash prevention plate 20, the liquid stop protrusion 20 a covers the adhering liquid, and the adhering liquid does not drip below the main body side wall 12. Moreover, when the liquid splash prevention plate 20 contacts the main body side wall 12 at the same time, it is possible to prevent the adhesion liquid from scattering downward. Thereafter, when the upper lid 3 is opened again, the adhering liquid adhering to the main body side wall 12 is swept up like a wiper by the liquid stop projection 20 a and guided to the groove 13. The induced adhesion liquid is discharged from the liquid discharge hole 14 communicating with the groove 13 to the back side of the cap body 2.

  Therefore, by using the hinge cap 1 of the present invention, it is not necessary to close the cover slowly so that the attached liquid does not scatter when the lid is closed, and the lid can be closed normally, and the attached liquid Does not hang down at the bottom of the main body side wall 20. Further, as an incidental effect of the groove portion 13, even if the content liquid adheres to a location where the liquid splash prevention plate 20 is not provided, the adhering liquid is pushed into the groove portion 13 by the upper lid 3 when the lid is closed. Therefore, the liquid is discharged from the liquid discharge hole 14 without dripping on the main body sidewall 12.

  The present invention is not limited to the above embodiment. For example, it is not always necessary to provide the recess 12a and the finger hook 12b in the main body side wall 12 and the liquid discharge hole 14 in the groove 13, and the groove 13 is continuously formed without being divided on both sides of the cap main body 2. Also good. Further, the shape and size of each part can be appropriately changed. For example, in the present embodiment, the blocking wall 8 is provided in a substantially triangular shape, but naturally, a circular shape, an elliptical shape, a U-shape, a polygonal shape, and other shapes can be appropriately employed. As a method for removing 8, a method using a device other than the pull ring 10 can also be selected as appropriate.
