Description

[Detailed explanation of the idea] "Industrial application field" The present invention relates to a bottle cap.

``Prior art'' A cap is removably fitted to the mouth and neck of a bottle, and by rotating the fitted cap, a cam action is obtained to mechanically raise the cap. There are some that allow the mating to be uncoupled.

``Problem that the invention aims to solve'' However, in this case, when uncoupling the fitting, it is necessary to hold the bottle with one hand and grasp the cap with the other hand and rotate it, in other words, a two-handed operation is required. It's inconvenient.

The present invention aims to solve the conventional inconvenience by making it possible to attach and detach with a simple one-handed operation.

"Means for Solving the Problems" The present invention provides an elastic engagement piece 12 that engages with an engagement protrusion Ab on the outer periphery of the bottle opening from the inner surface of the top wall 11 of the cap body 1 that closes the bottle opening Aa. is installed vertically, and both sides of the peripheral wall 13 hanging down from the edge of the top wall 11 are completely opened, and in the open part there is an L-shaped cross-section which also serves as a side wall and whose lower end faces the bottle shoulder part Ac. The levers 2, 2 are arranged with the lower ends facing inward,
It is characterized in that the corner of the lever is pivotally attached to the lower corner of the remaining part of the peripheral wall 13.

``Function'' With the above structure, when attaching the cap, all you have to do is place the cap main body 1 over the mouth Aa of the bottle A and press down, and the elastic engagement pieces 12...
engages with the engagement protrusion Ab of the bottle opening Aa, and becomes ready to be fitted. Also, at this time, the lower ends of the levers 2, 2 face the shoulder Ac of the bottle.

Next, when you want to remove it, just press levers 2, 2 with your fingers and pull them up.
At step 2, this action occurs and the cap body 1 is mechanically raised, and the elastic engagement pieces 12 are disengaged from the engagement protrusions Ab and are automatically removed.

"Example" The drawings show an embodiment of the invention.

In the figure, 1 is a cap body, 2 is a pair of left and right levers attached to both sides of the cap body and serves as side walls, and B is a bottle to which the cap is attached, and these are made of synthetic resin as appropriate.

The cap body 1 is formed into a rectangular shape that is sufficiently larger than the mouth Aa of the bottle A, and has a stopper cylinder 14 vertically disposed from the center of the inner surface of the top wall 11 to fit into the inside of the bottle mouth Aa. A plurality of elastic engagement pieces 12 that engage with the engagement protrusions Ab on the outer periphery of the bottle mouth are vertically provided around the cylinder, and extend from the entire area of both sides of the peripheral wall 13 that hangs down from the periphery of the top wall 11 to the end of the top wall. are cut out to form cut-out windows 15, 15 on both left and right sides, leaving both sides completely open.

The levers 2, 2 are formed to have an L-shaped cross section so that the lower end faces the bottle shoulder Ac while also serving as the left and right side walls of the cap body 1.
15 with its lower end facing inward, and is pivotally mounted 21, 21 to the lower corner of the remainder of the peripheral wall 13 on both sides of the lower corner.

Therefore, the lever 2,
A cantilevered shaft is provided on one side and a shaft hole is provided on the other between both side surfaces of 2 and the remainder of the peripheral wall 13, and the two sides are fitted together.

When it is attached to the mouth part Aa of the bottle A, it is placed over the mouth part and pushed down to fit the stopper cylinder 14 of the cap body 1 into the bottle mouth part, and the elastic engagement piece 12... is engaged with the engagement protrusion Ab on the outer periphery of the bottle mouth, and the lower ends of the levers 2, 2 are made to face the bottle shoulder Ac.

Next, when removing this, push in the left and right pair of levers 2, 2, and place the lower end of the lever on the shoulder of the bottle.
By hitting it against the AC and applying leverage,
The cap body 1 is forcibly raised, the elastic engagement pieces 12 are separated from the engagement protrusions Ab, and
Pull out the stopper cylinder 14 from the bottle mouth A and remove it from the mouth.

``Effect of the invention'' According to the invention, it is possible to immediately fit and engage the bottle opening by simply placing it over the bottle opening Aa and pushing it down, and by simply pressing and pulling up the levers 2, 2. Therefore, it can be easily and lightly attached and detached with one-touch operation with one hand, which is extremely convenient.

In addition, since both sides of the peripheral wall 13 are completely opened and the levers 2, 2 are arranged in the open part which also serves as the side wall, the pressing surface of the lever can be made wide and easy to press, and material is wasted. The lever has an L-shaped cross section and is arranged with its lower end pointing inward, and its corner is pivoted to the lower corner of the remaining peripheral wall 13. Therefore, there is little loss of force in the lever action, the structure and action can be rationalized, and it is easy to manufacture and can be provided at low cost, which is extremely useful in practice.
