Description

[Detailed Description of the Invention] The present invention relates to the structure of a bottle cap for sealing bottles for soy sauce, sake, etc.

Conventional stopper lids for 1.81 bottles, etc., have an inner stopper made of soft synthetic resin such as polyethylene that is locked onto the outer annular protrusion of the bottle mouth to seal it, or sealed on the inner circumference of the bottle mouth, and an inner stopper made of soft synthetic resin such as polyethylene. It consists of a metal crown that fits on the outside of the stopper, and these are integrally fitted to the mouth of the bottle and transported and sold at stores. Before use, the crown is removed with a bottle opener, and then the bottle is opened. Remove the inner stopper and
Dispense the liquid in the bottle.

For subsequent dispensing, the inner stopper must be removed from the mouth of the bottle, which is difficult to remove, and there is also the risk of losing the inner stopper.

In this invention, a lid with an inner stopper made of soft synthetic resin is hinged to a skirt part that is fitted and fixed to the outer periphery of the bottle mouth, and a knob attached to the lid can be freely engaged and detached from the skirt part. By locking, the mouth of the bottle is completely sealed and the liquid inside the bottle can be dispensed extremely easily.

Next, the present invention will be explained based on an example. In the figure, 1
is a bottle lid made of a soft synthetic resin such as polyethylene, and includes a lid body 3 shaped like a shallow dish to cover the upper surface of the bottle mouth part 2 and a skirt part such as a cylindrical shape surrounding the outer periphery of the bottle mouth part 2. 4, and an annular projection 6 is formed on the inner circumferential surface of the skirt portion 4 to engage with an annular projection 5 on the outer periphery of the bottle mouth portion 2.

On the lower surface of the lid body 3, an inner stopper 7 which is in close contact with the inner circumferential surface of the bottle opening 2 is integrally molded to protrude.

Further, one side part of the lid body 3 is integrally connected to the upper end of the skirt part 4 by a bendable hinge part 8, and the lower surface of the lid body 3 is approximately connected to the upper end surface of the skirt part 4. It is constructed so that it can freely rotate in a direction in which it approaches and in a direction in which it moves away from it so as to be parallel to each other.

A knob piece 9 is attached to the skirt portion 3 on the opposite side (180° away from the skirt portion 4) of the hinged portion of the lid body 3.
They are integrally connected approximately parallel to the upper end surface in a biased state due to the elasticity of the synthetic resin itself, and the knob pieces 9 are directed downward (approaching the outer surface of the skirt portion 4) and upward. It is configured to be bendable.

A pair of left and right convex engaging portions 10, 10 are provided on one side of the skirt portion 4), so that the knob piece 9 can be attached to the skirt portion 4.
While it can be locked in close contact with the outer surface, it is configured to be detachable so that it can be unlocked from now on.

Then, at a position in the vicinity of the lid body 3 and the skirt portion 4, which are appropriately separated from the knob piece 9 to the left and right, there is a joint portion between the lower end surface of the lid body 3 and the upper end surface of the skirt portion 4, which is appropriately thin and has a medium thickness h1. 11.11 is provided so that the lower surface of the lid body 3 can be held in a sealed state in contact with the upper surface of the bottle mouth part 2 or in a state substantially parallel to the upper end surface of the skirt part 4 at these joint parts 11.11. At the same time, when the lid body 3 is rotated upward while holding the knob 9, the side joint portions 11, 11 are torn off by the force.

Note that when the lid body 3 is rotated upwardly with respect to the bottle mouth part 2 in an open state around the eight hinged parts with the skirt part 4, the lower end of the inner stopper 7 is brought into contact with the upper end surface of the bottle mouth part 2. so that the lid body 3 can be held in position at an appropriate angle θ with respect to the upper surface of the bottle mouth part 2 by abutting.
The lower part of the inner stopper 7 of the lid body 3 is expanded into a trumpet shape, and the height h2 to the lower end of the inner stopper 7 is determined.

When the bottle lid 1 constructed in this way is pushed into the bottle opening 2 from the skirt 4 with the knob 9 shown in FIG. 1 removed from the locking part 10 of the skirt 4, 3
As shown in the figure, the annular protrusion 6 on the inner periphery of the skirt part 4 is engaged with the lower surface of the annular protrusion 5 on the outer periphery of the bottle mouth part 2, while the outer circumference of the lower end of the inner stopper 7 of the lid body 3 is attached to the inner periphery of the bottle mouth part 2. A close sealing effect can be obtained.

In this state, the lid body 3 and the skirt part 4 are integrally formed by the hinge part 8 and the joint part 11.11, so the lid body 3 alone will not come off, and the handle piece 9 will not come off from the skirt part 4. Even if it comes off, the lid 3 will not come off upward even if an upward force is applied to the lower end corner of the lid 3, so the liquid in the bottle will not spill out when the bottle is opened during transportation or the like.

Then, when the knob piece 9 is removed from the engagement part 10°10 of the skirt part 4 and the lid body 2 is pulled upward by the knob piece 9, the joint part 11.11 with the skirt part 4 is torn and the lid is removed. The body 3 can be rotated around eight hinge parts.

When opened to the state shown in FIG. 5, the inner stopper 7 prevents the lid 3 from moving in the closing direction, so the liquid in the bottle can be dispensed into a small bottle without having to hold the lid 3 in place with your fingers or the like.

After dispensing, the lid 3 can be sealed again with the inner stopper 7 by pressing toward the upper surface of the bottle mouth 2, and the knob 9 of the lid can be locked to the retaining part 10.10 on the outer surface of the skirt 4. It will not spill even if the bottle is knocked over.

According to the present invention, the lid with an inner stopper that can seal the inner periphery of the bottle mouth is rotatably connected at the hinge point on the upper end side of the skirt that fits and engages the outer periphery of the bottle mouth. Because of this, the bottle can be resealed with the lid with an inner stopper even after opening the mouth of the bottle, and there is no risk of losing the lid.

At the time of initial sealing, the lid body and the skirt portion are connected not only at the hinge portion but also at the joint portion, making the plugging operation extremely easy.

Furthermore, since the knob extending from the lid is closely locked to the outer surface of the skirt, it does not take up much space, and in this state, the lid cannot be removed due to upward external force applied to the lid. There is no risk of opening the package during transport or packaging.

In addition, since the separable joint is provided near the knob, it can be torn off extremely easily by the lifting force of the knob, and when the joint is provided near the hinge between the skirt and the skirt. There is no fear that the hinge portion will be damaged and the lid body and skirt portion will separate due to excessive force when lifting the knob.

In addition, if the inner stopper provided on the lower surface of the lid comes into contact with the upper surface of the bottle mouth when the lid is opened at a certain angle or more, the inner plug is formed so that the lid does not move freely in the closing direction. When taking out the liquid in the bottle, there is no need to hold the lid open with your fingers, making dispensing operations extremely easy.
