The hook (4) is arranged on the pivot bearing of the ring about an axis parallel to the axis (31) of the pivot bearing and is pivotable relative to the cover from the inside of the cover outwards to an operative end position, wherein the hook is arranged to pivot inwards of the cover when the cover is lowered towards the ring body and covers the hook.

Description

bottle opener

technical field

The invention relates to a bottle cap opener according to the preamble of claim 1 .

Background technique

The present invention relates to a bottle cap opener comprising a ring for placing on one of the user's fingers and comprising a cap pivotally mounted through a pivot bearing, the cap at the first rotational end position covering the hook , the hook is arranged on the ring body for clamping under the free edge portion of the crown cork, while the cover body at the second swivel end position is arranged to expose said hook and can be moved at a distance by A certain distance from the edge portion of the crown-shaped cork engaged by the hook forms a support for the crown-shaped cork.

In CA1141106, such a bottle cap opener has been disclosed.

In prior known bottle cap openers, the cap body is journalled in bearings to rotate about a rod parallel to the axis passing through the opening in the ring body so that the cap body and thus the hook act against the support force of the cap in the circumferential direction of the ring.

The disadvantage of said prior known bottle cap opener is that the opening operation of the bottle cap with the help of the bottle cap opener will subject the ring body to a torque in the circumferential direction of the ring body, which means that in the bottle cap The cap opener tends to rotate around the user's finger during the opening operation. As a result, on the one hand, it is difficult for the user to apply sufficient torque to the ring body, and on the other hand, when performing one or several bottle cap opening operations, the fingers may be injured due to friction with the ring body.

A further disadvantage of said prior known bottle cap opener is that said ring will occupy a certain diameter between the outside of the closed cap and the outer surface of the ring, i.e. in the area where the hooks are located. Thickness, because the bottle cap gripping part of the hook must have a certain radial protrusion outside the adjacent part of the ring when in operation, and the cap must be outside the hook in the radial direction in the closed state to protect The usually sharp point in a hook.

Contents of the invention

It is therefore an object of the present invention to provide a bottle cap opener with which one or more of the above-mentioned disadvantages can be completely or partially eliminated.

This object is achieved by the present invention.

The content of the invention is defined by the appended independent claims.

An embodiment of the invention is defined by the dependent claims.

Detailed ways

The bottle cap opener according to the invention comprises a ring body 1 having a radially thickened peripheral portion 2 supporting a cap body 3 . The finger opening portion 11 of the ring body 1 has an axis 12 . The cover body 3 is rotatable around a bearing axis 31 , the bearing axis 31 is arranged at one end of the ring body 1 and is on a plane orthogonal to the axis 12 , perpendicular to the axis 12 . In the ring part 2 a groove is provided, the bottom surface of which is located between two substantially parallel flanges along the thickened part 2 . The cover 3 has a folded free end flange 33 between the opposite ends of the flange 22 with respect to the thickened portion 2 of the ring to the bottom surface 21 of the groove when the cover 3 is in its closed position The isolation is formed, whereby the main part 3 of the cover forms the top of the recess 21. The outer side of the cover will then lie in the plane enclosed by the radially outer edge of the flange 22 and the outer side of the cover portion 33 lies entirely in the plane of the adjacent end of the ring thickened portion 2 . The clamping hook 4 comprises a generally L-shaped member having a long shank portion 42, the first free end portion 41 of which is rotatably mounted on the cover 3 about a pivot axis 31 parallel to the cover, as shown Preferably, it is set to rotate coaxially with the cover. Attached to the other end of the shank 42 is a short shank 43 which is generally perpendicular to the shank 42 and points away from the ring. In FIG. 5 there is shown a first end portion 41 of the handle 42 which is journalled about the handle of the shaft 31 for pivotal movement relative to the cover 3 and has a radial extension for At a predetermined position where the handle 42 is unscrewed in a direction away from the main surface of the cover body 3, an arcuate surface 46 is formed adjacent to the support surface 38 on the cover body. In this position in which the handle 42 is unscrewed relative to the cover 3, the direction of the short handle 43 is generally parallel to the plane of the cover 3, and the handle 42 is kept at a distance from the bottom surface 21 with the groove. In addition, the figure also shows that the crotch shank 43 protrudes upwards and exceeds the plane formed by the upper surface of the side flange 22, which is basically on the normal plane with respect to the axis 12 of the ring body, so that when the cover body 3 is lifted Grips precisely under the lip of the bottle cap. In Fig. 2-4, it is shown that the hook 4 has a certain width, which is a fraction of the width of the cover body 3, and is located in the middle of the width of the cover body. Furthermore, it is also shown that the cover body 3 has a bearing shoulder 34 on each side of the end 41 of the shank 42 . At least one of these shoulders 34 has a portion 61 protruding from the bearing rod 31 adjoining the bottom surface 21 of the groove to limit the unscrewing of the cover 3 to a position where the main part 3 of the cover is perpendicular to the bottom surface 21 of the groove .

When the cover body 3 is first lowered towards its end position allowing downward, the crotch 4 will begin to contact the bottom surface 21 of the groove. It is longer than the distance between the bearing rod 31 and the bottom surface 21 of the groove, but the crotch 4 can still rotate along the bearing 31 relative to the inner surface of the cover body 3, so that the cover body will be able to rotate downward towards its end position allowing downward , parallel to the bottom surface 21 of the groove.

Since the hook 44 is pivotably mounted in a bearing relative to the cover 3, the height of the groove 22 can be minimized so that the radial thickness of the ring in the area of the cover can be defined and since the cover 3 is unscrewed There is an end position stop, so the cap body 3 and the crotch 4 can exert a stable lifting force on the bottle cap due to the lifting torque around the axis parallel to the bearing 31.

The chamfer 50 is provided at a transition point between the bottom surface 21 of the groove and the end surface of the ring body opposite to the bearing 31 . Thereby, the fingernail can reach under the end of the lid flange 33 to promote lifting of the lid 3 from its closed position. Optionally, a protruding clamping flange 36 may be provided at the free end 36 of the lid flange 33 to further urge the lid 3 to move toward the open position. The cover 3 can thus have a friction fit in order to be easily releasably held in the closed position.

The bottle cap opener can be placed on any finger, so the ring body is preferably placed like this: the end of the ring body where the bearing 31 is located is closest to the palm. In addition, the bottle cap opener can also be placed in such a way that the cap body is located on the pulp of the lower finger.

Optionally, the releasable retention of the cover 3 in the closed position can be achieved with a slight friction, so that the user can accelerate the movement of the cover 3 by turning the hand or finger quickly, whereby the cover can be Unscrew to the open end position and bring the hook 4 into the operable position. Optionally, a spring may be provided to bias the hook 4 relative to the cover body 3 in a direction toward its unscrewed end position. Optionally, a snap lock can also be set to maintain the cover in the closed position with a small force.
