Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention relates to a synthetic resin cap.

"Prior Art" In order to make the cap two-tone, as shown in FIGS. 5 and 6, the cap body 1 and the lid body 2 are color-coded from each other and formed separately, while the lid rear edge is formed. A mounting plate 4 extending from the above through a thin hinge 3 is coupled to the rear edge of the cap body, and elastic protrusions (commonly called snap hinges) 5, 5 are located at both left and right sides of the mounting plate from the rear edge of the lid. When the lid 2 is rotated about the thin hinge 3, the tips of the elastic protrusions 5 and 5 are pressed against the upper surface of the cap body 1 so that the lid 2 can be elastically inverted. There is something.

[Problems to be solved by the invention] However, in the above-described conventional cap, the elastic projection pieces 5 and 5 and a part of the mounting plate 4 are largely exposed on the upper surface of the cap together with the cut line when the lid is closed. Therefore, there is a disadvantage that the appearance is not good and dust is accumulated on the score line to give a feeling of uncleanness.

Further, in the above-described conventional cap, the lid has a plate shape, and therefore, there is a drawback that it is difficult to form the ejection hole of the cap main body so as to facilitate the ejection of the content liquid. If the lid is formed in a tubular shape with an opening on the lower end surface such that the top wall extends from the upper edge of the peripheral wall, the rear part of the peripheral wall hangs on the top wall of the cap body, etc. There is also a possibility that the protruding piece cannot be reversed.

The present invention has been made in view of the above points, and has a good appearance and a clean feeling despite having an elastic protrusion capable of holding the opened and closed state of the lid, and the pouring hole. It is an object of the present invention to propose a superior synthetic resin cap which can be easily formed by projecting and forming a lid, and at which the opening angle can be made large.

[Means for Solving the Problems] In order to solve the above problems, the cap of the present invention is provided with the first peripheral wall 15
A first top wall 14 with a pouring hole 13 is extended from the upper end edge, and a fitting cylinder part for fitting the neck of the container body from the lower surface of the first top wall 15
The cap body 10 with 12 hung vertically and the cap body top wall
14 A second peripheral wall 22 having a lower surface abuttingly mounted on the peripheral edge of the upper surface, and a lid 11 formed by extending a second top wall 21 from the upper edge of the second peripheral wall 22. The rear outer surface of the second peripheral wall 22 is recessed forward. Shallow recess 23 formed by
In addition, the recess is shallower than the rear end of the top surface of the cap body.
Vertical plate 16a standing inside 23 Horizontal plate 1 extending from the upper end
A connecting plate (16) is fixed to the rear wall portion (22a) in the shallow recess (23) so that the connecting plate (16) cannot pass through and is fixed. 17, 1
7 is provided, and by rotating the lid body with respect to the cap body 10 around the thin hinge 18 provided at the intermediate portion in the up-down direction of the connecting plate, the lid body elastically deforms the elastic projection piece and then elastically deforms. It was constructed so that these protrusions could be restored and forcedly overcome.

[Operation] For example, when the lid 11 is rotated around the thin hinge 18 with respect to the cap body 10 from the state shown in FIG. 1, the lid 11 elastically deforms the elastic protrusions 17, 17 outward. After that, they are elastically restored to forcefully overcome these elastic protrusions (see FIG. 4). That is, the open state of the lid body is maintained by overcoming the above.

At this time, since the vertical plate portion 16a of the connecting plate 16 having the thin hinge 18 and the elastic protrusions 17, 17 are located in the shallow recess 23 of the rear wall portion of the lid peripheral wall, the height of the lid peripheral wall 22 is high. However, a sufficient opening angle can be obtained. Therefore, it is possible to make the pouring hole project to facilitate the pouring of the liquid.

When the lid is rotated in the opposite direction from the above state, the lid then elastically deforms the elastic protrusions inwardly and then elastically restores them to forcefully overcome these elastic protrusions and wall
The outer surface of 22a is in close contact with the inner surface of the elastic protrusion, and the closed state is maintained.

[Example] An example of a synthetic resin cap according to the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, the cap of the present invention is divided into a cap body 10 and a lid 11 and is divided into appropriate colors.

The cap body 10 extends a first top wall 14 with a spout hole 13 from the upper end edge of the first peripheral wall 15, and a fitting tubular portion 12 for fitting the neck of the container body from the lower surface of the center of the first top wall 14. It is made of synthetic resin. Then, from the rear portion of the first top wall 14, the inverted L-shaped connecting plate 16 and the elastic projecting pieces 17, 17 are respectively positioned on the left and right sides of the vertical plate portion 16a of the connecting plate, and the vertical plate portion is formed. Thin hinge 18 at the middle of 16a in the vertical direction
Is attached. In addition, the first top wall 14 around the pouring hole 13
The part is formed to be raised like a dome. In the figure
Reference numeral 19 indicates a fitting cylinder for sealing.

The lid 11 hangs a rod-shaped plug 20 that is detachably fitted into the pouring hole 13 from a second top wall 21, and a lower end surface of a second peripheral wall 22 hung from a peripheral edge of the top wall 21 is described above. It is made of synthetic resin and is placed on the outer peripheral portion of the upper surface of the first top wall 14. Then, a shallow concave portion 23 having a rear surface and a lower surface opening is formed on the outer surface of the rear wall portion 22a of the second peripheral wall 22, and a mounting hole 24 is formed in the rear wall portion located inside the shallow concave portion 23. The horizontal plate portion 16b of the connecting plate 16 described above is fitted and fixed in the mounting hole 24.

Then, by rotating the lid body 11 with respect to the cap body 10 about the thin hinge 18 from the state described above, the lid body 11 is rotated.
Is formed so that the elastic protrusions 17, 17 are elastically deformed outward and then elastically restored so that the elastic protrusions 17, 17 can be forcibly overcome. That is, as shown in FIG. 4, the projecting height of the elastic projecting pieces 17, 17 is selected so as to project by a predetermined dimension from the rotation locus C of the lid rear wall portion located at the shortest distance from the hinge point O. It has been done.

[Advantage of Device] As described above, according to the present invention, it is not necessary to expose the elastic projection or the like capable of holding the opened and closed state of the lid body together with the cut line to the upper surface of the cap.
It is possible to provide a cap that looks good and has a clean feeling because dust is not easily collected on the score line.

Further, the elastic protrusion and the vertical plate portion of the connecting plate can be completely accommodated in the shallow concave portion, and a cap having a small number of protruding portions can be provided, and a simple work of fitting the horizontal plate portion of the connecting plate into the mounting hole. Then, there is also an advantage that the lid can be attached to the cap body.

Furthermore, since each elastic protrusion and the connecting plate are located in the shallow recess provided in the rear wall of the peripheral wall of the lid, a sufficient opening angle can be maintained even if the lid has a high peripheral wall. result,
The pouring hole of the cap body can be made tall and easy to pour.
