Container lid with non-breaking connecting piece

The present invention relates to a synthetic resin container lid that opens and closes with a screw. In more detail, the container lid has a non-breakable connecting piece between the main body and the anti-theft ring, and the connecting piece enables the main body to remain connected after being released from the container mouth. The anti-theft ring is kept on the neck of the container.

The WO2010/004919 patent case discloses a synthetic resin container lid, which includes a main body and an anti-theft ring, which are connected by a plurality of breakable bridging parts. The thread is arranged on the inner surface of the skirt wall of the main body, and a plurality of coupling pieces are arranged on the inner surface of the anti-theft ring. A protruding piece extending downward is arranged on the bottom surface of the skirt wall of the main body, and the non-breaking connecting pieces are respectively arranged on both sides of the protruding piece and connecting the skirt wall and the anti-theft ring. Each of the two non-breakable connecting pieces includes two first inclined portions and second inclined portions whose inclined directions are opposite to each other, and the first inclined portion and the second inclined portion are connected via an intermediate portion. The inclination directions of the two non-breaking connecting pieces are opposite. The container cap is installed on the threaded container mouth, and the non-breaking connecting piece enables the main body to be connected with the anti-theft ring after being released from the container mouth, and the anti-theft ring is kept on the neck of the container mouth, and the container cap will not be separated from the container after opening.

The disadvantage of the above case to be improved is that the non-breaking connecting piece has only one first inclined part and one second inclined part and forms an included angle between them. The opening angle of the included angle is limited, so that the ascent distance of the main body relative to the anti-theft ring is limited. .

The non-broken connecting piece is not fully supported. When the container lid is installed on the container mouth, it may Cause the non-broken link piece to break.

In order to solve the above-mentioned problems, the present invention proposes a container lid with a non-breakable connecting piece.

In order to facilitate the description of the central idea of the present invention expressed in the column of the above-mentioned summary of the invention, specific embodiments are used to express it. The various objects in the embodiment are drawn according to the proportion, size, deformation or displacement suitable for explanation, rather than drawn according to the proportion of the actual element, which will be described first. In the following description, the same and symmetrically arranged elements are represented by the same numbers.

As shown in the first to fourth figures, the container cap of the present invention is integrally molded by injection or compression of a suitable synthetic resin material. The container cover includes a main body 10 and an anti-theft ring 20. The main body 10 includes a circular top wall 11 and a cylindrical skirt wall 12 extending downward from the circumference of the top wall 11. On the outer circumferential surface of the skirt wall 12, concavities and convexities 13 for preventing finger sliding are repeatedly formed. An internal thread 14 is formed on the inner circumferential surface of the skirt wall 12. The anti-theft ring 20 is connected to the skirt wall 12 of the main body 10 via a plurality of breakable bridge portions 21 arranged at intervals along the circumference. A plurality of abutting blades 22 are arranged on the inner circumferential surface of the anti-theft ring 20 at intervals, and each abutting blade 22 extends radially inward and upward from the inner circumferential surface of the anti-theft ring 20. The above configuration does not constitute the novel feature of the present invention.

As shown in the first and third figures, the skirt wall 12 and the anti-theft ring 20 respectively form a horizontal length in an opposite area 30 Rectangular openings 15, 23. A positioning blade 40 extending downward from the skirt wall 12 is formed in the center of the opening 15. The lower edge of the positioning blade 40 and the center of the opening 23 of the anti-theft ring 20 are connected by a breakable bridge 41.

As shown in the third, fifth, and sixth figures, two non-breakable connecting pieces 50 with the same shape and direction are also arranged in the openings 15, 23. The two non-breakable connecting pieces 50 are respectively located on the left and right parts of the positioning blade 40. The non-breakable connecting piece 50 includes an upper end 51 and a lower end 52. The upper end 51 is connected to the skirt wall 12 and the lower end 52 is connected to the anti-theft ring 20. The width W1 of the upper end 51 connected with the skirt wall 12 is greater than the width W3 of the unbreakable connecting piece 50 itself, and the width W2 of the lower end 52 connected with the anti-theft ring 20 is larger than the width W3 of the unbreakable connecting piece 50 itself to ensure that the upper end 51 and The lower end 52 will not break at any time.

The non-breakable connecting piece 50 further includes a first inclined section 56 and a second inclined section 57. The first inclined section 56 extends obliquely and downwardly toward one side in the circumferential direction after the upper end 51, and the second inclined section 57 extends obliquely and downwardly toward the other side of the circumferential direction after the first inclined section 56. The upper end 51 further includes a first oblique side 53, and a first included angle a1 is formed between the first oblique side 53 and the first inclined section 56. The first inclined section 56 and the second inclined section 57 form a second included angle a2. The lower end 52 further includes a second oblique side 54, and the second oblique side 54 and the second oblique section 57 constitute a third included angle a3. The lower end 52 further includes a third oblique side 55, and the third oblique side 55 and the bottom side of the opening 23 of the anti-theft ring 20 form a fourth included angle a4. The first included angle a1, the second included angle a2, and the third included angle a3 are approximately equal, and the fourth included angle a4 is smaller than the third included angle a3. The original angles of the above-mentioned included angles are all less than 30 degrees.

Each non-breakable connecting piece 50 is also provided with a breakable first bridge 58 and a breakable second bridge 59. The first bridge 58 connects the first oblique side 53 and the first inclined section 56, and the second bridge 59 connects the second oblique side 54 and the second inclined section 57.

As shown in Figure 8, the outer circumferential surface of the general container mouth 60 is formed with an external thread 61, and the external thread 61 There is a joint 62 below. The container cap of the present invention uses a known technology to install the container cap on the container mouth 60 in a complete state as shown in the first to third figures. The container cap is coupled to the outer thread 61 of the container mouth 60 with an internal thread 14 to prevent theft of the container cap. The ring 20 and its abutting blade 22 are located under the joint 62. The above-mentioned structural features of the non-breaking connecting piece 50 are beneficial to the non-breaking of the connecting piece 50 when the container lid is assembled to the container mouth 60 without breaking or deforming.

As shown in Figures 7 and 8, when the container lid is opened for the first time in a known manner, the main body 10 and the anti-theft ring 20 move upward as guided by the internal thread 14 and the external thread 61, and the anti-theft ring 20 abuts the blade 22 The anti-theft ring 20 immediately stops below the joint 62, and the anti-theft ring 20 generates rotational resistance. The rotating torsion of the main body 10 in the opening direction instantly disconnects the breakable bridge 21 between the main body 10 and the anti-theft ring 20. This is a known technology. The feature of the present invention is that the anti-theft ring 20 generates rotational resistance, and the rotational torque of the main body 10 in the opening direction is also transmitted to the bridge portion 41 of the positioning blade 40 and the first bridge 58 and the second bridge 59, causing all of them to be disconnected . Then continue to rotate the main body 10 in the opening direction. With the gradual release of the threaded engagement, the main body 10 rotates in the opening direction and rises. The distance between the main body 10 and the anti-theft ring 20 is getting larger and larger. At this time, the two non-breaking connecting pieces 50 The inclination angles of the first inclined section 56, the second inclined section 57, the first oblique side 53, the second oblique side 54, and the third oblique side 55 are getting larger and larger, the first included angle a1, the second included angle a2, and the third included angle The angles of a3 and the fourth included angle a4 also become larger and larger, until the threaded engagement between the internal thread 14 of the main body 10 and the external thread 61 of the container mouth 60 is completely released, and the body 10 is separated from the container mouth 60. When the bridging portion 41, the first bridging 58 and the second bridging 59 of the positioning blade 40 are all disconnected and the main body 10 is continuously rotated, the abutting blade 22 of the anti-theft ring 20 no longer presses against the joint 62 , The anti-theft ring 20 has no rotation resistance effect, and because it does not break the connecting piece 50, the anti-theft ring 20 will rotate with the main body 10 under the joint 62. Therefore, the connecting piece 50 will only be stretched but not broken. Will be reversed.

As shown in Figure 8, after the main body 10 is separated from the container mouth 60, the main body 10 can be turned over, so that the main body 10 can be pivoted away from the container mouth 60 with the unbroken connecting piece 50 as a hinge point, so that the beverage in the container can be taken from the container mouth 60 . Turn the main body 10 out of the container mouth 60 to position the outer circumferential surface of the blade 40 against the upper surface of the joint 62 of the container mouth 60, and the body 10 can be held in the position shown in the eighth figure, so that the container mouth 60 It is not hindered by the main body 10 at all. The main body 10 shown in Figure 8 is turned over toward the container mouth 60, the positioning blade 40 is elastically deformed and passes over the joint 62, and the body 10 returns to the container mouth 60 again. Then the main body 10 is rotated in the closing direction so that the internal thread 14 of the main body 10 is coupled to the external thread 61 of the container mouth 60, and the body 10 can temporarily close the container mouth 60.

In the above embodiment, the inclination directions of the two non-breakable connecting pieces 50 are the same. However, without changing the above-mentioned structural features, it is also feasible that the inclination directions of the two non-breakable connecting pieces 50 are opposite.
