Definitions

• the present invention relates to a cap or the like with a lid that reverses elasticity.
• a cap or the like means a container with a lid in addition to a cap.
• a so-called three-point hinge is used to connect the cap body and the lid to a synthetic resin.
• Caps which are integrally molded from a material are known. The cap is formed by integrally connecting a cap main body and a lid for opening and closing the upper surface of the cap main body via a three-point hinge, and the three-point hinge is formed on the upper end of the rear wall of the cap main body peripheral wall and on the cap main body.
• the lower end of the peripheral wall of the placed lid is connected to the left and right parts by first hinges, and the lower part of the first peripheral wall between the hinges and the lid on the upper end of the lid peripheral wall between the hinges.
• An L-shaped elastic plate is connected to the front part of the body top wall via second and third hinges.
• the lid peripheral wall portion in front of the rising portion of the L-shaped elastic plate and the lid top wall portion below the horizontal portion are made of metal. Notches will be cut out to remove the mold, so the notch on the top wall of the lid will damage the appearance of the lid, and because of the notch, it will be incomplete to close the mouth of the cap body with the lid plate. It was all.
• the present invention eliminates such a drawback and, as in the conventional example described above, attaches a horizontal plate to the elastic plate and extends the horizontal plate to the central portion of the top wall of the lid without removing the horizontal plate. It can be formed only between the rear parts of the cap body peripheral wall and the lid peripheral wall, so that notches need not be provided in the lid peripheral wall and the top wall, that is, the appearance of the lid is improved. It is provided so that the mouth of the cap body can be sealed with a lid when closed. Disclosure of the invention
• the middle portion of the elastic strip 12 may be curved forward.
• FIGS. 6 to 8 may be considered in the same manner as the first embodiment.
• the elastic strip 12 has a C-shape both when the cover is opened and when the cover is closed.
• the elastic strip 12 is housed in the recess 13. According to this embodiment, it is possible to prevent the elastic strip from being forcibly stretched beyond the limit even at the dead center A where the elastic strip is stretched most.
• FIG. 1 to 5 show a first embodiment of the cap and the like of the present invention, wherein FIG. 1 is a perspective view showing an opened state, FIG. 2 is a perspective view showing a closed state from the rear, and FIG. Fig. 4 is a plan view, Fig. 4 is an enlarged sectional view of a main part, Fig. 5 is an enlarged cross-sectional view of a main part in an open state, Figs. 6 to & show the second embodiment, and Figs. Is a perspective view when the lid is closed viewed from the rear side, FIG. 9 is a perspective view showing the lid in an open state, FIG. 8 is an enlarged sectional view of a main part, and FIGS. Fig. 9 shows a third embodiment, Fig. 9 is a perspective view in an open state, Fig. 10 is a perspective view of the closed state as viewed from the rear side, and Fig. 11 is an enlarged side view of a main part.
• Reference numeral 1 denotes a main body such as a cap having the first peripheral wall 2.
• the first peripheral wall 2 is formed on the peripheral wall to be fitted to the outer surface of the mouth and neck of the container body.
• the cap or the like is the container main body, the lower end surface of the first peripheral wall is formed. Is formed by closing the bottom wall.
• a top plate 4 with a pouring hole 3 is stretched on the upper surface of the first peripheral wall, but the top plate can be removed.
• ⁇ is a lid integrally formed of polyethylene or the like together with the main body, and is formed so that the upper surface of the first peripheral wall can be opened and closed by the movement about the hinge described later.
• the lid hangs down the second peripheral wall 7 from the outer periphery of the top wall 6 and places the lower end surface of the second peripheral wall 7 on the upper end surface of the first peripheral wall 2.
• the first peripheral wall 2 and the second peripheral wall 7 have a perfect circular shape in a plane, and a rear portion thereof is a vertical surface portion 8, and further, a groove 9 is provided vertically in the left and right middle of the vertical surface portion.
• the upper and lower ends of the right and left vertical surfaces of the grooves of the first and second peripheral walls 2 and 7 are connected by curved piece-shaped hinges 10 and 10, respectively, as shown in FIG.
• the upper end of the portion and the lower end of the groove bottom portion of the second peripheral wall are continuous, and holes 11, 11 are drilled in the first peripheral wall portion and the second peripheral wall portion in front of the continuous portion from the upper and lower end surfaces of each peripheral wall downward and upward.
• the bottom of the groove 9 behind these holes is formed in the elastic strip 12 by providing the holes.
• the elastic strip is formed to be curved in advance. As shown in FIG. 5, the lid 5 is opened with respect to the main body 1, and the elastic plate 12 is bent upward to form the main body 1 and the lid. What is necessary is just to integrally mold the body 5 with a synthetic resin material such as polyethylene.
• a continuous portion between the upper and lower ends of the elastic strip and the second and first peripheral walls is formed so as not to be bent.
• FIGS. 6 to 8 show the second embodiment, which is a vertical plane of the first embodiment described above. No part 8 and no groove 9 are provided.
• the upper and lower ends of the left and right portions of the rear surfaces of the first and second peripheral walls 2 and 7 each having a flat circular shape are connected to the rear ends of the protruding members 13 and 13 which protrude rearward in a triangular shape.
• the elastic strip 12 is connected between the hinges 10 and 10 between the lower first peripheral wall and the upper second peripheral wall so that both upper and lower ends of the elastic strip cannot be bent by the peripheral walls. It is stretched continuously.
• the cap and the like of the second embodiment also have the main body and the lid integrally formed in a closed state.
• FIG. 9 to 11 show a third embodiment.
• the upper and lower rear ends of the first and second peripheral walls 2 and 7 each having a planar perfect circular shape are connected by a hinge 10, and a pair of C-shaped elastic members are formed on both left and right sides of the hinge. ⁇ Connected by plates 12,12.
• the elastic strip is provided with a continuous recess 13 between the upper and lower portions of the rear surfaces of the first and second peripheral walls 2, 7.
• the lower and upper ends of the elastic strips 12 and 12 are connected via second and third hinges 14 and 15, and the elastic strips 12 and 12 are accommodated in the recess 13.
• the cover is formed in an open state as shown in FIG.
• the cap and the like of the present invention have the above-described configuration, the rear portion of the lid peripheral wall and a part of the lid top wall are cut out and the cut-out portion is used like a conventionally known three-point hinged cap.
• the lid does not have a cutout portion, its appearance is not impaired, and the upper surface of the main body such as a cap can be sealed by the lid.
• the elastic band plate since the elastic band plate has a C-shaped vertical cross section, even when the end of the elastic band plate on the lid side passes through the dead center, the elastic band plate can be passed with a margin for elastic deformation.
• the C-shaped elastic band ⁇ is stored in the concave portion 13 formed in the rear of the first and second peripheral walls of the main body and the lid, so that the elastic band plate looks like a cap or the like. There is no loss.
