Description

An easy-to-grip and twist plastic bottle cap

technical field

The utility model belongs to the technical field of bottle caps, in particular to a plastic bottle cap which is easy to grasp and twist.

Background technique

Daily bottled food, such as mineral water, fruit juice drinks, edible oil, etc., in order to prevent adulteration by illegal personnel, usually use specially designed plastic bottle caps. The sleeve is intermittently connected to the lower side of the cover wall through several short thin plastic columns. During packaging, as the plastic bottle cap is screwed onto the bottle mouth, the anti-counterfeiting ring is tightly fitted and stuck on the outer wall of the bottle mouth. Usually, it needs external force to destroy the anti-counterfeiting ring to remove it. In order to make the plastic bottle cap airtight on the bottle mouth , the plastic bottle cap must be screwed on the bottle mouth with a large pre-tightening force. When in use, people usually use the thumb, index finger and middle finger to hold the bottle cap and screw it outward. Since the anti-counterfeiting ring is tightly fitted and stuck on the outer wall of the bottle mouth, several short and thin plastic columns Will snap off, remove the plastic cap to use the bottled food. In the prior art, the outer surface of the plastic bottle cap cover is usually provided with vertical stripes, which can increase the frictional force of screwing the plastic bottle cap, but for some people with less strength, the fingers are still there when the bottle cap is screwed off. It will slip on the cover wall of the plastic bottle cap, and the finger will hurt but it will not be opened as expected.

SUMMARY OF THE INVENTION

The utility model mainly solves the technical problems in the above-mentioned prior art, and provides a plastic bottle cap that is easy to grasp and twist.

The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: a plastic bottle cap that is easy to grasp and twist, including a cover bottom plate and a cover peripheral wall integrally connected to the cover bottom plate, the front of the cover peripheral wall The side surface is provided with a thumb groove corresponding to the thumb groove, and the rear side surface of the cover wall is provided with an index finger groove and a middle finger groove, and the index finger groove is on the left side of the middle finger groove.

Preferably, the edges of the thumb pressing groove, the index finger pressing groove and the middle finger pressing groove are all smoothly connected with the peripheral wall of the cover.

As a preference, the thumb press groove is elliptical, its long axis is arranged along the circumference of the cover wall, and its short axis is arranged axially along the cover wall; the index finger press groove is elliptical, its upper end exceeds the cover wall, and its long axis The included angle α of the tangent line of the cover wall is 55-65 degrees; the middle finger press groove includes a main body press groove and a horizontal press groove, the main body press groove is elliptical, its upper end exceeds the cover surrounding wall, and the lower end extends laterally to form a horizontal press groove, and the main body The angle β between the major axis of the groove and the tangent line of the cover wall is 50-60 degrees.

Preferably, the middle finger is smoothly connected with the main body of the groove and the horizontal groove.

The utility model adds a groove conforming to the hand shape of the human body on the ordinary bottle cap, and the bottle cap can be easily opened by using three fingers. When in use, point the thumb groove of the plastic bottle cap towards you, and hold the thumb, index finger, and middle finger in the thumb groove, index finger groove, and middle finger groove respectively, so that the fingers can feel it without too much friction When you feel pain, use the natural force of your fingers to open the bottle cap. It conforms to the ergonomic design, and has the characteristics of simple structure and reasonable design.
