Description

[Detailed description of the invention] This invention relates to a bottle cap that is attached to the mouth of a bottle.

Conventionally, as shown in FIG. 6, in a bottle lid b fitted to a bottle mouth a, the lid c is rotatably provided on the main body d by a hinge, and a protrusion is provided on the rotating end of the lid c. This protrusion e stands up against the circumferential surface of the bottle spout a when the lid c rotates to open, and this protrusion e acts as a stopper for the rotation of the lid c in the closing direction. When ordering the contents of
The lid c is designed so that it does not cover the bottle mouth a.

However, this type of lid generally has the following drawbacks. That is, since this type of lid uses the elasticity of the synthetic resin to seal the mouth of the bottle, when an attempt is made to open the lid, the protrusion e rises against the elasticity for sealing. It must be opened until it is completely closed, which requires a relatively large amount of force.

For this reason, this type of bottle lid is somewhat unsuitable for use by people with limited power, such as children in the household.

This invention was made to solve such problems, and its purpose is to provide a bottle cap of the above type that can be opened more easily than the conventional bottle cap. To describe this invention in terms of embodiments, in FIGS. 1, 7, and 8, an inner lid 4 and a lid 5 are connected to both ends of a plate-shaped hinge 1 made of synthetic resin through thin parts 2 and 3. A recess 11 for accommodating the hinge 1 is formed in a part of the outer periphery of the inner lid 4, and a hole-shaped engaged portion 6 formed in the hinge 1 is inserted into the recess 11. A protruding engaging portion 7 for press-fitting is provided, and a hole 17 is further formed at the end of the hinge 1 on the lid 5 side, and a thickness T formed at a part of the periphery of the lid 5 is provided in the hole 17.
A tongue-like projection 8 having a shape is accommodated, and the projection 8
This bottle lid is characterized in that it is formed to be able to move in and out of the hole 17 as the lid 5 rotates with respect to the hinge 1. In the figure, 12 is a spout, 13 (Fig. 5) is a stopper, 14 is a knurling, 15 is a shoulder,
16 (Figure 4) is the recess, 18 (Figure 5) is the bottle, 1
9 and 20 are threads, and 21 is an aluminum foil sealing member.

When using this lid, first, as shown in FIG. 5, remove the bottle lid from the bottle 18, remove the sealing member 21 or make a hole, and then attach the bottle lid to the bottle 18 again and use it.

When opening the bottle lid, place a fingertip on the recess 16 shown in FIG. 4 and open the lid 5 in the direction of arrow A5.

In this case, the protrusion 8 tries to rotate, and the rotation is blocked by the surface of the recess 11, but the protrusion 8
rotates while pressing the surface of the recess 11 with its tip. (See FIG. 8) At this time, the end of the hinge 1 on the side of the lid 5 is formed into a thin part 3, and the press-fitting engagement between the engaging part 7 and the engaged part 6 is slightly released. Due to the displacement in the direction, so-called escape of force occurs, and the protrusion 8 of the lid 5 moves beyond the point of elasticity into the recess 1 with less force than the conventional one.
1 rise to the surface.

Since the protrusion 8 that has risen in this way has risen beyond the point of consideration as described above, it cannot go back past the point of consideration as it is, and therefore the bottle opening is tilted to drain the contents. Do not cover the mouth of the bottle when pouring.

When closing this lid, when the lid 5 is pushed in the closing direction, the protrusion 8 rotates while pressing against the surface of the recess 11, and is urged by the elasticity of the hinge 1, and the projection 8 rotates while pressing against the surface of the recess 11. Close the lid 4.

This device is constructed as described above, and when the lid 5 is opened, the protrusion 8 is raised up from the side surface of the inner lid 4, but since the end 3 of the hinge 1 is formed thin, it can be easily raised. Elastic deformation occurs, and the press-fitting engagement between the engaging portion 7 and the engaged portion 6 is such that the press-fitting engagement of this portion is slight because both 6 and 7 are openable and press-fittingly engaged. However, the lid 5 shifts in the opening direction, resulting in so-called force escape, and therefore the lid 5 can be opened with a smaller force than in the conventional example.
