[0002] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 568,056, filed on March 21, 2024, the entire contents of which are incorporated herein by reference. Technical Field
[0003] The utility model relates to the field of tools for opening sealed containers, in particular to a container opener. Background Art
[0004] Bottles, jars, or other containers with lids must be opened before their contents can be used or consumed. However, some lids have smooth, tight outer surfaces that make them difficult to grasp and open by hand.
[0005] In order to solve this problem, people usually use various container openers, such as wrenches, pliers, vises and other tools to open the lid. However, existing container openers still have some shortcomings that need to be further optimized.
[0006] For example, a wrench, while simple and low-cost, only works with a single bottle size. An opener with gear teeth can accommodate a variety of cap sizes. However, before opening the cap, the user needs to manually increase the friction between the gear teeth and the cap for a certain period of time. This can be difficult for people with limited hand strength, such as the elderly or children.

[0030] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0031] It should be understood that although the terms "first", "second", etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another.
[0032] It should also be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description, in some embodiments, refer to directions in the accompanying drawings. The terms "inner" and "outer" are used to refer to directions toward and away from, respectively, the geometric center of a particular component. These terms are intended to encompass orientations of the device in addition to the orientations depicted in the drawings.
[0033] The present disclosure relates to a container opener configured for opening caps and other closures. The container opener precisely adjusts the length of a strap to accommodate caps of varying sizes. Once adjusted, the strap length can be locked to prevent the container opener from loosening during the opening process. Furthermore, the container opener provides reliable friction with the cap, effectively preventing relative rotation when tightly fitted. Furthermore, the container opener features an ergonomic design to enhance user-friendliness.
[0034] Although the word "container" is often used in this disclosure, any type of container is contemplated including, but not limited to, bottles, jars, cans, vials, jugs, cans, buckets, and all other containers.
[0035] As shown in Figures 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 extending along a longitudinal axis from a front end adapted to engage a container lid to a rear end opposite the front end, and the cavity 13 is configured to accommodate the adjustment mechanism 3.
[0036] For ease of description, in the embodiments of the present disclosure, the end close to the container is defined as the front end, and the end away from the container is defined as the rear end.
[0037] The adjustment mechanism 3 includes a guide member, a moving block 32 and a strip 33. The guide member is arranged in the cavity 13 and extends along the longitudinal axis. The moving block 32 is connected to the guide member and is configured to move relative to the housing 1. In one embodiment, the guide member includes a threaded rod 31 and a guide rail 34. The threaded rod 31 is arranged in the housing 1 and is rotatably connected to the housing 1. The threaded rod 31 extends along the longitudinal axis. An opening is provided on the housing 1 at the rear end corresponding to the threaded rod 31. The guide rail 34 is provided in the housing 1 and extends parallel to the threaded rod 31. The moving block 32 is provided with a threaded hole that cooperates with the threaded rod 31 and a sliding interface that is operably connected to the guide rail 34 to prevent the moving block 32 from rotating. The guide member and the moving block 32 cooperate to form a mechanism similar to a screw mechanism, which is configured to convert rotational motion into linear motion. The rotation of the threaded rod 31 causes the moving block 32 to move along the threaded rod 31 and the guide rail 34.
[0038] The middle portion of the strip 33 is located outside the front end of the housing 1, and its two ends extend into the housing 1 and are connected to the movable block 32. As the movable block 32 moves along the threaded rod 31, the strip 33 moves with the movable block 32, and the length of the strip 33 extending from the housing 1 also changes accordingly to accommodate lids of different sizes.
[0039] The handle 2 is operatively connected to the threaded rod 31 to drive its rotation, thereby adjusting the position of the moving block 32 and the strap 33. The handle 2 and the threaded rod 31 can be connected by a spline.
[0040] In one embodiment, the front end of the housing 1 is provided with two symmetrical through-holes. The ends of the strip 33 extend into the cavity 13 through their respective through-holes. The ends of the strip 33 are connected to opposite sides of the moving block 32, ensuring uniform and synchronized motion of the two ends of the strip 33.
[0041] The housing 1 has a curved surface located between the two through-holes, and the curved surface cooperates with a portion of the strip 33 extending to the outside of the housing 1 to define a receiving space configured to receive a container lid. The configuration of the curved surface can adapt to the shape of the lid.
[0042] In one embodiment, the curved surface includes a friction portion 14 disposed on a side facing the receiving space. The friction portion 14 contacts the lid and increases the friction between the friction portion 14 and the lid, thereby preventing the container opener from rotating relative to the lid during the opening process. In addition, the friction portion 14 is configured to provide a cushioning effect, thereby preventing damage to the housing 1. In other embodiments, the strip 33 includes a friction portion 14 disposed on a side facing the receiving space. In other embodiments, both the curved surface and the strip 33 include a friction portion 14 disposed on a side facing the receiving space.
[0043] The friction portion 14 may include a plurality of protrusions. The friction portion 14 is an elastomer and provides a cushioning effect when the locking strip 33 is engaged, thereby protecting the housing 1 and / or the container lid from damage. The friction portion 14 may be formed of rubber or other materials having elastic properties.
[0044] 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.
[0045] The handle 2 is concentrically disposed around the longitudinal portion of the first section 11 and is rotatably connected to at least a portion of the first section 11. As shown in FIG6 , the handle 2 may comprise a tubular structure having an annular protrusion disposed on its inner wall, and a corresponding annular groove defined on the outer wall of the first section 11. The annular protrusion slidably engages the annular groove, thereby achieving a rotational connection between the handle 2 and the housing 1.
[0046] 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. The handle 2 has substantially the same cross-sectional dimension as the rear end of the second section 12, so that when the handle 2 is mounted on the first section 11, its overall dimension substantially matches the second section 12, thereby improving visual continuity and aesthetics.
[0047] The cross-sectional dimension of the first section 11 tapers gradually from the front end to the rear end, so that the inner wall of the first section 11 is configured to constrain the position of the strap 33, thereby reducing the possibility of torsional deformation of the strap 33 and ensuring smooth extension and retraction of the strap 33. To facilitate the user's grip, the handle 2 maintains a substantially constant cross-sectional dimension.
[0048] The front end of the second section 12 defines two through holes, and the strip 33 extends through the through holes. Specifically, the cross-sectional shape of the front end of the second section 12 is substantially rectangular, and the cross-sectional shape of the rear end of the second section 12 is substantially circular, which conforms to the design principle of ergonomics.
[0049] The front end of the threaded rod 31 is rotatably connected 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 that the threaded rod 31 rotates smoothly in the housing 1.
[0050] In one embodiment, the first section 11 is composed of two detachably connected first half-shells. The second section 12 is composed of two detachably connected second half-shells. The detachable connection of the half-shells allows the user to easily disassemble the shell 1 to inspect, repair or replace internal components. Each first half-shell is integrally formed with the corresponding second half-shell, thereby enhancing durability and simplifying assembly. The two first half-shells can be connected by bolts or snap fits. As shown in Figures 4 and 5, a ring body is sleeved on the rear end of the first section 11 to enhance the connection reliability between the two first half-shells. The two first half-shells can be connected by bolts or snap fits.
[0051] In one embodiment, the first section 11 is composed of two detachably connected first half shells, and the second section 12 is composed of two detachably connected second half shells. Each first half shell is detachably connected to a corresponding second half shell.
[0052] In one embodiment, the rear end of the threaded rod 31 is provided with an external spline, and the handle 2 is provided with an internal spline. The external spline and the internal spline mate at the opening of the housing 1. The internal spline is provided at the rear end of the interior of the handle 2, thereby extending the mating length between the handle 2 and the housing 1. The handle 2 can also be operably connected to the threaded rod 31 via other drive connection mechanisms known in the art, wherein the drive connection mechanism is configured to transmit rotational motion from the handle 2 to the threaded rod 31.
[0053] As shown in Figure 7, in one embodiment, a fixing element 22 is provided at the rear end of the handle 2. The fixing element 22 is connected to the rear end of the threaded rod 31 to ensure a secure connection between the handle 2 and the threaded rod 31. The fixing element 22 can be a bolt. A plate is detachably connected to the rear end of the handle 2 to conceal the fixing element 22, thereby enhancing the aesthetics.
[0054] The handle 2 may be provided with an anti-slip texture on its surface to enhance the grip and facilitate the user to apply rotational force.
[0055] As shown in Figures 1 and 8, in one embodiment, the container opener further includes a locking assembly 4. The locking assembly 4 is slidably mounted on the housing 1 and is configured to engage with the handle 2. The locking assembly 4 can be operated between a locked position and an unlocked position. In the locked position, the locking assembly engages with the handle 2 to prevent the handle 2 from rotating, and in the unlocked position, the locking assembly disengages from the handle 2 to allow the handle 2 to rotate. After the length of the strip 33 is adjusted into place, the locking assembly 4 locks the relative position of the handle 2 and the housing 1 to prevent the threaded rod 31 from rotating, thereby ensuring that the length of the strip 33 extending out of the housing 1 remains fixed. In addition, this engagement method can prevent the connection between the container opener and the lid from loosening.
[0056] The locking assembly 4 includes an outer ring gear 41, which is slidably mounted on the first section 11 along the longitudinal axis. The front end of the handle 2 is provided with inner gear teeth 21 that mesh with the outer ring gear 41. When engaged, the outer ring gear 41 and the inner gear teeth 21 cooperate to lock the rotational movement of the handle 2 without restricting axial movement. To release the locking assembly 4, the outer ring gear 41 slidably moves relative to the inner gear teeth 21, achieving smooth disengagement.
[0057] A plurality of first gear teeth are circumferentially spaced apart on the outer wall of the outer gear ring 41. Each first gear tooth extends axially along the housing 1. Internal gear teeth 21 are disposed on the inner wall of the handle 2. At least one of the first gear teeth and the internal gear teeth 21 is arranged along a complete 360-degree circumference. For example, the first gear teeth are arranged in a continuous 360-degree array, and the internal gear teeth 21 are arranged in segmented arcs between 30 and 360 degrees of the inner wall. The first gear teeth and the internal gear teeth 21 are configured to selectively mesh with each other upon axial displacement of the locking assembly 4.
[0058] An outer ring 42 is provided on outer ring gear 41. Outer ring 42 is configured to allow a user to move outer ring gear 41 by manipulating outer ring gear 42. Outer ring 42 is sleeved onto outer ring gear 41 and connected to the end of outer ring gear 41 remote from handle 2, such that axial movement of outer ring gear 42 adjusts the position of outer ring gear 41. A gap is defined between the inner wall of outer ring gear 42 and outer ring gear 41. The thickness of this gap is no less than the thickness of the wall of handle 2, thereby preventing interference with the outer ring gear 41's entry into handle 2.
[0059] The outer race 42 may be connected to the distal end of the outer gear ring 41 by a rod or a plate.
[0060] When the length of strap 31 extending outside of housing 1 needs to be adjusted, the outer ring 42 is slid to disengage the outer gear ring 41 from the inner gear teeth 21, allowing handle 2 to rotate freely to drive threaded rod 31 for length adjustment. When the desired length of strap 33 is reached, the outer ring 42 is slid to align and engage the outer gear ring 41 with the inner gear teeth 21, thereby locking the position of handle 2 and threaded rod 31 and preventing accidental rotation. The locking assembly 4 provides multiple contact points for engagement with handle 2, ensuring a secure locking effect.
[0061] In one embodiment, the inner wall of the outer gear ring 41 defines a sliding groove extending along the longitudinal axis. As shown in Figure 3, the outer wall of the first section 11 is correspondingly provided with a ridge-like protrusion that slidably engages with the sliding groove. The ridge and the sliding groove provide guidance for the linear motion of the movable outer gear ring 41. One or more ridges can be spaced circumferentially along the first section 11, and one or more sliding grooves can be correspondingly arranged to correspond to the ridges.
[0062] The sliding range of the outer ring gear 41 allows for complete separation and full engagement between the inner gear teeth 21 and the outer ring gear 41. When the outer ring 42 is slid to its rearmost position, the outer ring gear 41 is fully engaged with the inner gear teeth 21, thereby establishing a locked state. When the outer ring 42 is slid to its forwardmost position, the outer ring gear 41 is completely disengaged from the inner gear teeth 21, thereby establishing an unlocked state.
[0063] In one embodiment, the sliding range of the locking assembly 4 is defined by the rear edge of the second segment 12 and the front edge of the handle 2. Because the cross-sectional dimensions of the first segment 11 are smaller than those of the rear end of the second segment 12, when the outer gear ring 41 slides forward to its maximum extent, it contacts the rear edge of the second segment 12, thereby preventing the outer gear ring 41 from moving further forward. When the outer gear ring 41 slides rearward to its maximum extent, the connection between the outer gear ring 41 and the outer ring 42 contacts the front edge of the handle 2, thereby preventing the outer gear ring 41 from moving further rearward.
[0064] In one embodiment, as shown in FIG. 1 , the housing 1 is provided with a direction indicator on its outer surface to indicate the rotation direction for locking or unlocking.
[0065] As shown in Figures 5 and 9, in one embodiment, the locking assembly 4 further comprises a washer 43 mounted on the first section 11. The washer 43 is located between the outer gear ring 41 and the first section 11, and its outer wall is in sliding contact with the inner wall of the outer gear ring 41.
[0066] Two washers 43 can be installed above the first section 11, one at the front and one at the rear of the ridge. The outer surface of the washers 43 is flush with the bottom surface of the ridge. This configuration ensures alignment between the washers 43 and the ridge and allows the outer gear ring 41 to move smoothly.
[0067] The container opener provides a versatile and user-friendly solution for opening containers of different sizes. The container opener's adjustment mechanism, locking assembly and ergonomic design make it a significant improvement over traditional container openers.
[0068] A method for operating a container opener includes:
[0069] (a) Slide the locking assembly 4 to disengage the outer gear ring 41 from the inner gear teeth 21;
[0070] (b) rotating the handle 2 to rotate the threaded rod 31, causing the moving block 32 to move along the extension direction of the threaded rod 31, thereby adjusting the length of the strip 33 extending outside the housing 1, thereby adjusting the accommodation space;
[0071] (c) inserting the lid into the receiving space formed by the protruding portion of the strip 33 and the arcuate surface, or moving the container opener to allow the lid to pass through the receiving space;
[0072] (d) rotating the handle 2 to establish close contact between the strip 33, the friction portion 14 and the lid;
[0073] (e) Sliding the locking assembly 4 so that the outer gear ring 41 engages with the inner gear teeth 21, thereby locking the position of the handle 2 and maintaining the position stability of the strap 33;
[0074] (f) rotating the entire container opener so that the container opener and the lid rotate relative to the container; or, rotating the entire container opener and the container in opposite directions at the same time, thereby opening the lid.
[0075] In some applications, the container opener can also be used as a tool for tightening the lid onto the container.
[0076] The container opener utilizes the principle of leverage to transfer force applied to the lid to the container opener. The contact point between the lid and the container opening serves as the lever's fulcrum, with handle 2 serving as the other end. Applying force to handle 2 away from the fulcrum allows the lid to be opened or closed with less effort.
[0077] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
