Description

Technical Field

[0001] The present disclosure generally relates to the field of tools for opening sealed containers, and more specifically, to container openers.

Background Art

[0002] Bottles, jars, and other capped containers need to be opened to use or consume their contents. However, some caps have a smooth and tight outer peripheral surface, making it difficult to manually grip and open them.

[0003] To address this issue, people generally use various container openers, such as wrenches, pliers, vise grips, and other tools, to open the caps. However, existing container openers have some drawbacks and further optimization is needed.

[0004] For example, a wrench has the advantages of simple structure and low cost, but it can only handle a single bottle size. Openers with gear teeth can accommodate various cap sizes. However, with these openers, it is necessary to manually increase the friction between the gear teeth and the cap for a long time before opening the cap, which can be difficult, especially for people with limited hand strength, such as the elderly or children.

Modes for Carrying Out the Invention

[0018] Hereinafter, the technical content according to the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings. It should be understood that other embodiments that can be obtained by those skilled in the art based on the embodiments of the present application without creative efforts are naturally included in the protection scope of the present application. It should be explicitly understood that the drawings are not intended to limit the present application, but are only provided for explanation and understanding.

[0019] Here, terms such as "first", "second", etc. are used to distinguish different components, and it should be understood that these terms do not limit these components.

[0020] Furthermore, terms such as "front", "rear", "left", "right", "above", "below", etc. used hereinafter refer to directions in the specific embodiments shown in the drawings. These terms are also used to refer to directions towards or away from the geometric center of a specific member. It should also be understood that these terms can be applied in other postures in addition to the described posture.

[0021] The present disclosure relates to a container opener configured to open a cap or other closure. The container opener can accurately adjust the length of a strip to accommodate bottle caps of different sizes. Once the adjustment is completed, the length of the strip can be locked to prevent the container opener from loosening during the cap opening operation. Furthermore, the container opener provides reliable friction with the cap and effectively prevents relative rotation when in close contact. In addition, the container opener is designed considering ergonomics and provides a user-friendly feeling of use.

[0022] Note that although the term "container" is often used in the present disclosure, it is not limited thereto and includes bottles, jars, canisters, medicine bottles, jugs, cans, drum cans, and any other containers.

[0023] As shown in FIGS. 1 to 4, the container opener includes a housing 1, an adjustment mechanism 3, and a handle 2. The housing 1 defines a cavity 13 that extends longitudinally from a front end adapted to engage with a container cap towards a rear end located on the opposite side of the front end, and the cavity 13 is configured to accommodate the adjustment mechanism 3.

[0024] To facilitate the description of embodiments of the present disclosure, an end portion close to the container is defined as the front end, and an end portion away from the container is defined as the rear end.

[0025] The adjustment mechanism 3 includes a guide member, a moving block 32, and a strip 33. The guide member is disposed within the cavity 13 and extends along the longitudinal direction. The moving block 32 is coupled to the guide member and is configured to be movable relative to the housing. In one embodiment, the guide member includes a threaded rod 31 and a rail 34. The threaded rod 31 is disposed within the housing 1 and is rotatably coupled to the housing 1. The threaded rod 31 extends along the longitudinal direction. The housing 1 is provided with an opening corresponding to the rear end of the threaded rod 31. The rail 34 is disposed within the housing 1 and extends parallel to the threaded rod 31. The moving block 32 is provided with a threaded hole that meshes with the threaded rod 31 and a sliding interface that operatively engages with the rail 34 to prevent rotation. The guide member and the moving block 32 cooperate to form a mechanism similar to a lead screw mechanism, which is configured to convert rotational motion into linear motion. When the threaded rod 31 is rotated, the moving block 32 moves along the threaded rod 31 and the rail 34.

[0026] The strip 33 has an intermediate portion located outside the front end of the housing 1, both ends extending into the housing 1 and being connected to the moving block 32. When the moving block 32 moves along the threaded rod 31, the strip 33 also moves together with the moving block 32, and the length of the strip 33 extending from the housing 1 changes to adapt to caps of different sizes.

[0027] The handle 2 is operatively coupled to the threaded rod 31 to drive the rotation of the threaded rod 31. Thereby, the positions of the moving block 32 and the strip 33 are adjusted. The handle 2 and the threaded rod 31 may be coupled by a spline.

[0028] In one embodiment, two through holes arranged symmetrically are provided at the front end of the housing 1. Both ends of the strip 33 extend into the cavity 13 through the corresponding through holes respectively. Both ends of the strip 33 are connected to the opposite sides of the moving block 32 respectively, so that the operating states of both ends of the strip 33 are uniform and synchronized.

[0029] The housing 1 has an arc-shaped surface, and the arc-shaped surface is arranged between the two through holes. The arc-shaped surface cooperates with a part of the strip 33 extending outside the housing 1 to define a receiving space configured to receive the container cap. The configuration of the arc-shaped surface can be adaptively adapted to the contour of the cap.

[0030] In one embodiment, the arc-shaped surface includes a friction portion arranged on the side facing the receiving space. The friction portion 14 is in contact with the cap, increasing the frictional force therebetween, thereby preventing the container opener from rotating with respect to the cap during the cap opening process. Further, the friction portion 14 is configured to provide a cushioning effect, thereby preventing damage to the housing 1. In other embodiments, the strip 33 is provided with a friction portion arranged on the side facing the receiving space. In still other embodiments, both the arc-shaped surface and the strip 33 are provided with friction portions arranged on the side facing the receiving space.

[0031] The friction portion 14 may include a plurality of protrusions. The friction portion 14 has elasticity and provides a buffering effect when locking the strip 33, preventing damage to the housing 1 and / or the container cap. The friction portion 14 can be formed of rubber or other materials having elastic properties.

[0032] As shown in FIG. 3, in one embodiment, the housing 1 includes a first section 11 and a second section 12 extending from the front end of the first section 11. The first section 11 has a circular cross-section, and the opening is located at the rear end of the first section 11.

[0033] The handle 2 is concentrically arranged around the longitudinal portion of the first section 11 and is rotatably coupled to at least a part of the first section 11. As shown in FIG. 6, the handle 2 has a cylindrical structure with an annular protrusion provided on the inner wall, and a corresponding annular groove is formed on the outer wall of the first section 11. The annular protrusion is slidably coupled to the annular groove, thereby realizing a rotatable connection between the handle 2 and the housing 1.

[0034] The cross-sectional dimension of the first section 11 is smaller than the cross-sectional dimension at the rear end of the second section 12. The handle 2 has substantially the same cross-sectional dimension as the rear end of the second section 12. Thus, when the handle 2 is mounted on the first section 11, the overall dimension substantially coincides with that of the second section 12, improving visual continuity and aesthetics.

[0035] The first section 11 has a configuration in which the cross-sectional dimension gradually decreases from the front end to the rear end. Thereby, the inner wall of the first section 11 is configured to restrict the position of the strip 33, reducing the possibility of torsional deformation of the strip 33 and ensuring smooth expansion and contraction of the strip 33. To facilitate the user's grip, the handle 2 maintains a substantially constant cross-sectional dimension.

[0036] Two through holes are formed at the front end of the second section 12, and the strip 33 extends through these through holes. Specifically, the front end of the second section 12 has a substantially rectangular cross-sectional shape, and the rear end of the second section 12 has a substantially circular cross-sectional shape, conforming to the ergonomics design principle.

[0037] The front end of the threaded rod 31 is rotatably coupled to the front end of the second section 12. The rear end of the threaded rod 31 is rotatably supported by a support plate fixedly connected to the rear end of the first section 11, thereby ensuring smooth rotation of the threaded rod 31 within the housing 1.

[0038] In one embodiment, the first section 11 is formed by detachably coupling two first half-housings. The second section 12 is formed by detachably coupling two second half-housings. By the detachable coupling of the half-housings, the user can easily disassemble the housing 1 to inspect, repair, or replace the internal components. Each first half-housing is integrally formed with the corresponding second half-housing, thereby improving durability and simplifying assembly. The two first half-housings can be coupled by bolt connection or snap-fit connection. As shown in FIGS. 4 and 5, a ring is fitted on the rear end of the first section 11, thereby improving the connection reliability between the two first half-housings. The two first half-housings can be coupled by bolt connection or snap-fit connection.

[0039] In one embodiment, the first section 11 is formed by detachably coupling two first half-housings. The second section 12 is formed by detachably coupling two second half-housings. Each first half-housing is detachably coupled to the corresponding second half-housing.

[0040] In one embodiment, an outer spline is provided at the rear end of the threaded rod 31, and an inner spline is provided in the handle 2. The outer spline and the inner spline mesh at the opening of the housing 1. The inner spline is provided at the rear end inside the handle 2, thereby extending the meshing length between the handle 2 and the threaded rod 31. Further, the handle 2 is configured to be operatively coupled to the threaded rod 31 via other drive connection mechanisms known to those skilled in the art, thereby enabling the transmission of rotational motion from the handle 2 to the threaded rod 31.

[0041] As shown in FIG. 7, in one embodiment, a fixing member 22 is provided at the rear end of the handle 2. The fixing member 22 is coupled to the rear end of the screw rod 31, thereby ensuring a highly reliable connection between the handle 2 and the screw rod 31. The fixing member 22 may be a bolt. A plate for concealing the fixing member 22 is detachably coupled to the rear end of the handle 2, thereby improving the aesthetic appearance.

[0042] The handle 2 may be provided with a non-slip texture on its surface to improve the grip force and facilitate the application of rotational force by the user.

[0043] As shown in FIGS. 1 and 8, in one embodiment, the container opener further includes a locking mechanism 4. The locking mechanism 4 is slidably mounted on the housing 1 and configured to engage with the handle 2. The locking mechanism 4 is operable between a locked position where it engages with the handle 2 to prevent rotation of the handle 2 and an unlocked position where it disengages from the handle 2 to allow rotation of the handle 2. After the length of the strip 33 is adjusted to a desired position, the locking mechanism 4 locks the relative positions of the handle 2 and the housing 1, thereby preventing rotation of the screw rod 31 and fixing the length of the strip 33 extending from the housing 1. Further, this engagement can also prevent the container opener from loosening with respect to the cap.

[0044] The locking mechanism 4 includes an outer peripheral gear ring 41. The outer peripheral gear ring 41 is slidably mounted on the first section 11 along the longitudinal direction. An internal tooth portion 21 configured to mesh with the outer peripheral gear ring 41 is provided at the front end of the handle 2. In the engaged state, the outer peripheral gear ring 41 and the internal tooth portion 21 cooperate to lock the rotational movement of the handle 2 while not restricting the axial movement. To release the locking mechanism 4, the outer peripheral gear ring 41 is slid relative to the internal tooth portion 21 to smoothly disengage.

[0045] The outer gear ring 41 includes a plurality of first teeth arranged at intervals in the circumferential direction along the outer wall. Each first tooth extends along the axial direction of the housing 1. The internal tooth portion 21 is provided on the inner wall of the handle 2. The arrangement of the first teeth and the internal tooth portion 21 is such that at least one of them is arranged over the entire 360-degree circumference. For example, the first teeth may be arranged as a continuous 360-degree circular array, and the internal tooth portion 21 may be arranged in an arc-shaped section ranging from 30 degrees to 360 degrees of the inner wall. The first teeth and the internal tooth portion 21 are configured to selectively mesh with each other due to the axial displacement of the locking mechanism.

[0046] The outer ring 42 is disposed on the outer gear ring 41 and is configured such that the user can move the outer gear ring 41 by operating the outer ring 42. The outer ring 42 is fitted over the outer gear ring 41 and is coupled to the end of the outer gear ring 41 away from the handle 2, and the position of the outer gear ring 41 is adjusted by the axial movement of the outer ring 42. A gap is formed between the inner wall of the outer ring 42 and the outer gear ring 41, and the thickness of the gap is greater than or equal to the wall thickness of the handle 2, so that the outer gear ring 41 does not interfere with the inside of the handle 2.

[0047] The outer ring 42 may be connected to the distal end of the outer gear ring 41 via a rod or a plate.

[0048] When it is necessary to adjust the length of the strip 31 extending outside the housing 1, the outer ring 42 is slid to disengage the outer gear ring 41 from the internal tooth portion 21. Thereby, the handle 2 can rotate freely, and the length adjustment is performed by driving the screw rod 31. After reaching the desired length of the strip 33, the outer ring 42 is slid again, so that the outer gear ring 41 aligns and meshes with the internal tooth portion 21. Thereby, both the handle 2 and the screw rod 31 are fixed in position, and unintentional rotation can be prevented. The locking mechanism 4 provides a plurality of contact points that engage with the handle 2, thereby ensuring a reliable locking effect.

[0049] In one embodiment, a sliding groove extending in the longitudinal direction is formed on the inner wall of the outer peripheral gear ring 41. As shown in FIG. 3, a ridge that slidably engages with the sliding groove is correspondingly provided on the outer wall of the first section 11. The linear motion of the movable outer peripheral gear ring 41 is guided by the ridge and the sliding groove. A plurality of ridges may be arranged at intervals in the circumferential direction along the first section 11, and a plurality of corresponding sliding grooves may be provided in alignment on the outer peripheral gear ring 41.

[0050] The sliding range of the outer peripheral gear ring 41 is a range that enables both complete engagement and complete disengagement between the internal tooth portion 21 and the outer peripheral gear ring 41. When the outer ring 42 is slid to the maximum rear position, the outer peripheral gear ring 41 is fully meshed with the internal tooth portion 21, and a locked state is established. When the outer ring 42 is slid to the maximum front position, the outer peripheral gear ring 41 is completely disengaged from the internal tooth portion 21, and an unlocked state is established.

[0051] In one embodiment, the sliding range of the locking mechanism 4 is defined by the trailing edge of the second section 12 and the leading edge of the handle 2. Since the cross-sectional dimension of the first section 11 is smaller than the cross-sectional dimension of the rear end of the second section 12, when the outer peripheral gear ring 41 slides forward to the maximum extent, it contacts the trailing edge of the second section 12 and prevents further forward movement. Also, when the outer peripheral gear ring 41 slides backward to the maximum extent, the connection position between the outer peripheral gear ring 41 and the outer ring 42 contacts the leading edge of the handle 2 and prevents further backward movement.

[0052] In one embodiment, as shown in FIG. 1, a direction indication mark indicating the rotational direction for locking or unlocking is provided on the outer surface of the housing 1.

[0053] As shown in FIGS. 5 and 9, in one embodiment, the locking mechanism 4 further includes a washer 43. The washer 43 is mounted on the first section 11 and is interposed between the outer peripheral gear ring 41 and the first section 11. The washer 43 has an outer wall that makes sliding contact with the inner wall of the outer peripheral gear ring 41.

[0054] Two washers 43 are mounted on the first section 11 and are located at the front end and the rear end of the protrusion respectively. The outer surface of the washer 43 is flush with the bottom surface of the protrusion. With this configuration, the alignment between the washer 43 and the protrusion is ensured, and the outer peripheral gear ring 41 can move smoothly.

[0055] This container opener provides a multi - purpose and user - friendly solution for opening containers of different sizes. It has been significantly improved compared with conventional container openers due to its adjustment mechanism, locking mechanism and ergonomic design.

[0056] The operation method of this container opener includes the following: (a) Slide the locking mechanism 4 to disengage the outer peripheral gear ring 41 from the internal tooth portion 21; (b) Rotate the handle 2 to rotationally drive the screw rod 31, move the moving block 32 along the extending direction of the screw rod 31, thereby adjusting the length of the strip 33 extending outside the housing 1 and adjusting the accommodation space; (c) Insert the cap into the accommodation space composed of the extending portion and the arcuate surface of the strip 33, or move the container opener to pass the cap through the accommodation space; (d) Rotate the handle 2 to establish close contact between the strip 33, the friction portion 14 and the cap; (e) Slide the locking mechanism 4 and engage the outer peripheral gear ring 41 with the internal tooth portion 21 to lock the handle 2 in a predetermined position and maintain the position stability of the strip 33; (f) Rotate the entire container opener and rotate it relative to the container with the container opener gripping the cap; Alternatively, the cap is opened by rotating the container opener and the container in opposite directions simultaneously.

[0057] In some usage scenarios, this container opener can also be used as a tool for tightening the cap on the container.

[0058] This container opener utilizes the lever principle to transmit the force applied to the cap to the container opener. The contact point between the cap and the container opening functions as the fulcrum of the lever, and the handle 2 functions as the other end of the lever. By applying a force to the handle 2 located at a position away from the fulcrum, the cap can be opened or tightened with a smaller force.

[0059] Finally, it should be noted that the above description illustrates some embodiments of the present application and does not limit the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art can make modifications to the technical solutions described in the above embodiments or equivalently substitute some technical features. Any modifications, equivalent substitutions, improvements, etc. made based on the spirit and principles of the present application shall be included in the protection scope of the present application.
