Description

a bottle cap

technical field

The invention relates to a bottle cap.

Background technique

In the known existing feeding bottle products, an outer cover is usually used to cover the nipple to keep the nipple hygienic. In order to prevent the cover from falling off accidentally, the cover and the feeding bottle are usually tightly fitted. That is to say, in use, if the outer cover needs to be removed, a relatively large external force needs to be applied. Generally, two hands are required to coordinate the operation to complete. However, the situation often faced in daily use is that the user holds the baby in one hand and feeds the baby with a feeding bottle in the other hand. At this time, if the outer cover is not removed, it will be difficult for the user to remove the outer cover.

On the other hand, in the design of the outer cover of the existing feeding bottle, in order to maintain a certain appearance and feel, it is usually designed such that the outer diameter gradually decreases from the open end to the closed end, and the surface is smooth. This design requires more external force to remove the outer cover. It is usually difficult to remove the cover with one hand. Referring to the prior art bottle cap 100 of FIG. 1 , the radial dimension of the bottle cap gradually decreases from the open end 102 to the closed end 101 . The outer surface of the bottle cap is usually relatively smooth. When the opening end of the bottle cap 100 fits closely with the bottle body, it needs to use a relatively large force to remove the bottle cap, and both hands need to be coordinated. If you hold the bottle body with one hand, push the bottle cap with your thumb or index finger to try to remove the bottle cap, since the direction of the thumb or index finger force is mostly distributed to the tangential direction of the bottle cap surface, so that the thumb points to the closed end Sliding, it is obviously difficult to remove this bottle cap.

Therefore existing this feeding bottle cover design is inconvenient for the user.

The eleventh kind of scheme of the present invention is:

A bottle cap comprising:

open and closed ends;

The outer diameter of the bottle cap is substantially the same from the open end to the closed end to form a substantially cylindrical outer surface, at least one area of the cylindrical outer surface includes a convex or concave inclined surface;

The distance between the inclined surface and the edge of the opening is between 15mm and 60mm;

The included angle between the tangent line outward from the cover body and the direction line pointing from the open end to the closed end of at least a partial area of the inclined surface is in the range of 5 degrees to 75 degrees;

The diameter of the bottle cap from the opening end to the position of the inclined surface is less than 80 mm.

The bottle body matched with this solution can be held by ordinary people with one hand, and then the thumb is placed on the inclined surface. The cap opens from the bottle body. Due to the unique design of the scheme, when exerting force, the thumb is not easy to slide out of the inclined surface due to the blocking effect of the inclined surface, so that the bottle cap is easier to open from the bottle body.

In the various schemes above, when the bottle cap is in tight fit contact with the bottle body, due to the existence of the inclined surface, and at least a partial area of the inclined surface is outwardly tangent from the cap body and points from the opening end to the The included angle between the direction lines of the above-mentioned closed ends is in the range of 5 degrees to 75 degrees. When people hold the bottle body with one hand, touch the inclined surface with the thumb of the hand, and then apply force, the inclined surface will prevent With the sliding of the thumb, the force effectively acts on the inclined surface, making it easier to remove the cap from the bottle body. Through multiple experiments, it has been found that, on the one hand, if the included angle is less than 5 degrees, the inclined surface is nearly parallel to the direction line from the open end to the closed end, and when the thumb acts on the inclined surface, sliding is easy to occur And not easy to open the bottle cap. On the other hand, if the included angle is greater than 75 degrees, the inclined surface is nearly perpendicular to the direction line from the open end to the closed end. When bent to such an angle, it is difficult for the thumb to apply force on the inclined surface, so it is not easy to open the bottle cap. The optimal angle range is 10 degrees to 30 degrees. Within this range, it is basically consistent with the natural bending angle of the thumb, and it becomes easier and more comfortable when the thumb is exerting force.

In the various solutions above, the inclined surface may be a curved surface or a plane. A preferred embodiment, the inclined surface is an arc surface. A better solution is: the inclined surface is a curved surface matching the contact surface of the thumb, which is more comfortable to operate and easier to open the bottle cap.

In the above-mentioned various schemes, on the one hand, since the human hand must hold the bottle body and act on the inclined surface with the thumb of the hand, the bottle cap can be opened, so the distance between the inclined surface and the opening end of the bottle cap should not be too long, otherwise the thumb will It cannot touch the inclined surface; it cannot be too short, otherwise the area where the thumb touches the inclined surface is too small, and it is not easy to open the bottle cap. After experiments, this distance is between 15mm and 60mm. A better solution is that the distance is between 25 mm and 40 mm, and most people's thumbs are more suitable for this length.

On the other hand, in the above-mentioned various schemes, the caliber of the bottle cap from the opening end to the position of the inclined surface should not be too large, otherwise the caliber of the corresponding bottle body is also large, and it is not easy to hold it firmly by hand, and In this case, it is difficult for the thumb to exert an active force on the inclined surface, and it is not easy to open the bottle cap. Through experiments, it is more appropriate that the size of the aperture from the opening end to the position of the inclined surface is less than 80 mm. A preferred solution is that the diameter of the opening from the opening to the position of the inclined surface is between 30mm and 60mm.

The "tangent from the cover outward" described in the above various solutions refers to the tangent to a point on the inclined surface, and its positive direction is from the inside of the bottle cap to the outside of the bottle cap at this point.

The "direction line from the open end to the closed end" described in the above-mentioned various schemes refers to that after the bottle cap is placed on the bottle body, when the bottle body is placed on a horizontal surface in a normal placement manner, the earth's gravity line in the opposite direction.

The bottle cap of the present invention realizes the function of opening the bottle cap with one hand in a very simple manner through innovative design. Since the outer surface of the cover between the open end and the closed end includes at least one inclined surface, when the inclined surface acts as a contact surface for applying force, the bottle cap can be opened from the bottle body by one-handed operation. By optimizing the inclination angle of the inclined surface, the caliber of the bottle cap and the position of the inclined surface on the outer surface of the bottle cap, not only the bottle body and the bottle cap are easier to hold in the hand, but also the removal of the bottle cap becomes easier with one hand. Easier.
