[0002] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 568,056, filed March 21, 2024, the entire contents of which are incorporated herein by reference. Technical Field
[0003] This utility model relates to the field of tools for opening sealed containers, and more particularly to a container opener. Background Technology
[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 surfaces that are difficult to grip and open by hand.
[0005] To address this issue, various container openers are commonly used, such as wrenches, pliers, vises, and other tools, to open lids. However, existing container openers still have some shortcomings that require further optimization.
[0006] For example, wrenches are characterized by their simple structure and low cost, but they are only suitable for bottles of a single size. Openers with gears can accommodate multiple cap sizes. However, before opening the cap, the user needs to manually increase the friction between the gears and the cap and maintain this for a period of time. This can be difficult for people with limited hand strength (such as the elderly or children). Utility Model Content
[0007] The topics disclosed in this article include container openers for opening sealed containers.
[0008] The container opener includes a housing with a cavity extending along a longitudinal axis from a front end adapted to engage a container lid to a rear end opposite the front end. An adjustment mechanism is disposed within the cavity and includes a guide member disposed within the cavity and extending along the longitudinal axis, a movable block connected to the guide member and configured to move relative to the housing, and a strip partially located outside the front end of the housing, the two ends of the strip extending into the cavity and connected to the movable block. A handle is operatively connected to the adjustment mechanism to drive movement of the movable block.
[0009] The container opener also includes various features for improved functionality and ease of use. According to one or more embodiments of this disclosure, the guide includes a threaded rod rotatably connected to the housing and extending along the longitudinal axis, the guide rail being disposed within the cavity and parallel to the threaded rod.

[0013] The front end of the threaded rod is rotatably connected to the front end of the second segment. The rear end of the threaded rod is rotatably connected to the rear end of the first segment.
[0014] According to one or more embodiments of this disclosure, the container opener further includes a locking component slidably mounted on the housing and operable between a locked position and an unlocked position. In the locked position, the locking component engages with the handle to prevent movement of the handle, and in the unlocked position, the locking component disengages from the handle to allow movement of the handle.
[0015] According to one or more embodiments of this disclosure, the locking assembly includes an outer gear ring and an outer ring. The outer gear ring is slidably mounted on the housing and configured to move along the longitudinal axis. The inner wall of the handle has inner gear teeth configured to engage with the outer gear ring. The outer ring surrounds the outer gear ring and connects to the end of the outer gear ring remote from the handle. The thickness of the gap between the inner wall of the outer ring and the outer wall of the outer gear ring is not less than the wall thickness of the handle. The inner wall of the outer gear ring defines a groove extending along the longitudinal axis. The housing includes ridge-like projections protruding from its outer wall and slidably connected to the groove.
[0016] The outer toothed ring has first gear teeth spaced circumferentially on its outer wall. At least one of the first gear teeth and the inner gear teeth is distributed along a complete 360-degree circumference. The locking assembly also includes a washer mounted on the housing and located between the outer toothed ring and the housing.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0030] It should be understood that although the terms "first," "second," etc., may be used here to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another.
[0031] It should also be noted that the terms “front,” “rear,” “left,” “right,” “up,” and “down” used in the following description refer to directions in the accompanying drawings in some embodiments. The terms “inner” and “outer” refer to directions toward or away from the geometric center of a particular component, respectively. In addition to the orientations described in the accompanying drawings, these terms should also cover other orientations of the device.
[0032] This disclosure relates to a container opener configured to open caps and other closures. The container opener precisely adjusts the length of the strip to accommodate caps of different sizes. Once adjusted, the strip length can be locked to prevent the container opener from loosening during the opening process. Additionally, the container opener provides reliable friction with the cap, effectively preventing relative rotation when tightly fitted. Furthermore, the container opener is designed with ergonomic features to enhance user-friendliness.
[0033] Although the term “container” is frequently used in this disclosure, any type of container is intended, including but not limited to bottles, jars, cans, medicine bottles, kettles, jugs, barrels and all other containers.
[0034] like Figures 1 to 4 As shown, the container opener includes a housing 1, an adjustment mechanism 3, and a handle 2. The housing 1 has a cavity 13 that extends 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.
[0035] For ease of description, embodiments of this disclosure define the end closer to the container as the front end and the end farther from the container as the back end.
[0036] The adjusting mechanism 3 includes a guide, a moving block 32, and a strip 33. The guide is disposed within the cavity 13 and extends along the longitudinal axis. The moving block 32 is connected to the guide and configured to move relative to the housing 1. In one embodiment, the guide includes a threaded rod 31 and a guide rail 34. The threaded rod 31 is disposed within the housing 1 and rotatably connected to it. The threaded rod 31 extends along the longitudinal axis. An opening is provided on the housing 1 corresponding to the rear end of the threaded rod 31. The guide rail 34 is disposed within the housing 1 and extends parallel to the threaded rod 31. The moving block 32 has a threaded hole that mates with the threaded rod 31 and a sliding interface operably connected to the guide rail 34 to prevent rotation of the moving block 32. The guide 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. Rotation of the threaded rod 31 causes the moving block 32 to move along the threaded rod 31 and the guide rail 34.
[0037] The middle part of the strip 33 is located on the outer 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 out of the housing 1 also changes accordingly to accommodate lids of different sizes.
[0038] The handle 2 is operably connected to the threaded rod 31 to drive its rotation, thereby adjusting the position of the moving block 32 and the strip 33. The handle 2 and the threaded rod 31 can be connected by a spline.
[0039] In one embodiment, the front end of the housing 1 has two symmetrically arranged through holes. Each end of the strip 33 extends into the cavity 13 through a corresponding through hole. The two ends of the strip 33 are respectively connected to opposite sides of the moving block 32, ensuring uniform and synchronized movement at both ends of the strip 33.
[0040] The housing 1 has an arcuate surface located between two through holes, and the arcuate surface cooperates with a portion of a strip 33 extending to the outside of the housing 1 to define a receiving space configured to receive a container lid. The arcuate surface is constructed to conform to the shape of the lid.
[0041] In one embodiment, the arcuate surface includes a friction portion 14 disposed on the 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. Furthermore, 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 the side facing the receiving space. In other embodiments, both the arcuate surface and the strip 33 include a friction portion 14 disposed on the side facing the receiving space.
[0042] The friction part 14 may include multiple protrusions. The friction part 14 is an elastomer and provides a cushioning effect when the locking strip 33 is engaged, thereby protecting the housing 1 and / or container lid from damage. The friction part 14 may be formed of rubber or other materials with elastic properties.
[0043] like Figure 3 As shown, in one embodiment, the housing 1 includes a first segment 11 and a second segment 12 extending from the front end of the first segment 11. The first segment 11 has a circular cross-section, and the opening is located at the rear end of the first segment 11.
[0044] The handle 2 is concentrically arranged around the longitudinal portion of the first segment 11 and is rotatably connected to at least a portion of the first segment 11. For example... Figure 6 As shown, the handle 2 may include a tubular structure, the inner wall of which is provided with annular protrusions, and the outer wall of the first segment 11 defines a corresponding annular groove. The annular protrusions and the annular grooves are slidably connected, thereby realizing the rotational connection between the handle 2 and the housing 1.
[0045] The cross-sectional dimension of the first segment 11 is smaller than the cross-sectional dimension of the rear end of the second segment 12. The handle 2 has a cross-sectional dimension that is substantially the same as the rear end of the second segment 12, so that when the handle 2 is mounted on the first segment 11, its overall size is substantially matched with the second segment 12, thereby improving visual continuity and aesthetics.
[0046] The cross-sectional dimensions of the first segment 11 gradually taper from the front end to the rear end, allowing the inner wall of the first segment 11 to be configured to constrain the position of the strip 33, thereby reducing the possibility of torsional deformation of the strip 33 and ensuring the smooth extension and retraction of the strip 33. For ease of grip, the handle 2 maintains a substantially constant cross-sectional dimension.
[0047] The front end of the second segment 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 segment 12 is substantially rectangular, and the cross-sectional shape of the rear end of the second segment 12 is substantially circular, which conforms to the design principles of ergonomics.
[0048] The front end of the threaded rod 31 is rotatably connected to the front end of the second segment 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 segment 11, thereby ensuring that the threaded rod 31 rotates smoothly within the housing 1.
[0049] In one embodiment, the first segment 11 consists of two detachably connected first half-shells. The second segment 12 consists 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 its corresponding second half-shell, thereby enhancing durability and simplifying assembly. The two first half-shells can be connected by bolts or snap-fit. Figure 4 and Figure 5 As shown, a ring is fitted onto the rear end of the first segment 11 to enhance the connection reliability between the two first half-shells. The two first half-shells can be connected by bolts or snap-fit.
[0050] In one embodiment, the first segment 11 consists of two detachably connected first half-shells. The second segment 12 consists of two detachably connected second half-shells. Each first half-shell is detachably connected to a corresponding second half-shell.
[0051] In one embodiment, the threaded rod 31 has an external spline at its rear end, and the handle 2 has an internal spline. The external spline and the internal spline mate at the opening in the housing 1. The internal spline is located at the rear end inside the handle 2, providing an extended mating length between the handle 2 and the housing 1. The handle 2 can also be operatively connected to the threaded rod 31 via other drive connection mechanisms known in the art, configured to transmit rotational motion from the handle 2 to the threaded rod 31.
[0052] like Figure 7As shown, 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 reliable 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 hide the fixing element 22, thereby enhancing aesthetics.
[0053] The handle 2 can be textured with a non-slip surface to enhance grip and make it easier for the user to apply rotational force.
[0054] like Figure 1 and Figure 8 As shown, in one embodiment, the container opener further includes a locking component 4. The locking component 4 is slidably mounted on the housing 1 and configured to engage with the handle 2. The locking component 4 is operable between a locked position and an unlocked position; in the locked position, it engages with the handle 2 to prevent rotation of the handle 2; in the unlocked position, it disengages from the handle 2 to allow rotation of the handle 2. After the length of the strip 33 is adjusted to the correct position, the locking component 4 locks the relative position of the handle 2 and the housing 1, preventing rotation of the threaded rod 31, thereby ensuring that the length of the strip 33 extending out of the housing 1 remains fixed. Additionally, this engagement method prevents the connection between the container opener and the lid from becoming loose.
[0055] The locking assembly 4 includes an external gear ring 41. The external gear ring 41 is slidably mounted on the first section 11 along the longitudinal axis, and the front end of the handle 2 is provided with internal gear teeth 21 that mesh with the external gear ring 41. In the engaged state, the external gear ring 41 and the internal gear teeth 21 cooperate to lock the rotational movement of the handle 2 without restricting axial movement. To release the locking assembly 4, the external gear ring 41 can slide relative to the internal gear teeth 21 to achieve smooth disengagement.
[0056] The outer toothed ring 41 has a plurality of first teeth spaced circumferentially on its outer wall. Each first tooth extends axially along the housing 1. Inner teeth 21 are disposed on the inner wall of the handle 2. At least one of the first teeth and inner teeth 21 is arranged along a complete 360-degree circumference. For example, the first teeth are arranged in a continuous 360-degree circumferential array, and the inner teeth 21 are arranged in segmented arcs between 30 degrees and 360 degrees on the inner wall. The first teeth and inner teeth 21 are configured to selectively engage by axial displacement of the locking assembly 4.
[0057] An outer ring 42 is provided on the outer gear ring 41. The outer ring 42 is configured to allow the user to move the outer gear ring 41 by operating the outer ring 42. The outer ring 42 is fitted onto the outer gear ring 41 and connected to the end of the outer gear ring 41 away from the handle 2, so that the axial movement of the outer ring 42 can adjust the position of the outer gear ring 41. The inner wall of the outer ring 42 defines a gap with the outer gear ring 41, the thickness of which is not less than the thickness of the wall of the handle 2, so as not to interfere with the outer gear ring 41 entering the handle 2.
[0058] The outer ring 42 can be connected to the distal end of the outer gear ring 41 via a rod or plate.
[0059] When the length of the strip 31 extending beyond the housing 1 needs adjustment, the sliding outer ring 42 disengages the outer gear ring 41 from the inner gear tooth 21, allowing the handle 2 to rotate freely to drive the threaded rod 31 for length adjustment. When the desired length of the strip 33 is reached, the sliding outer ring 42 aligns and engages the outer gear ring 41 with the inner gear tooth 21, thereby locking the handle 2 and the threaded rod 31 to prevent accidental rotation. The locking assembly 4 provides multiple contact points that engage with the handle 2, ensuring a secure locking effect.
[0060] In one embodiment, the inner wall of the outer gear ring 41 defines a groove extending along the longitudinal axis, such as... Figure 3 As shown, the outer wall of the first segment 11 is provided with a ridge-like protrusion that slides in conjunction with the slide groove. The ridge-like protrusion and the slide groove provide guiding linear movement for the movable outer gear ring 41. One or more of the ridge-like protrusions may be spaced apart circumferentially along the first segment 11, and one or more of the slide grooves may be arranged accordingly to correspond to the ridge-like protrusions.
[0061] The sliding range of the outer gear ring 41 allows for complete disengagement and engagement between the inner gear teeth 21 and the outer gear ring 41. When the outer ring 42 is slid to its rearmost position, the outer gear ring 41 is fully engaged with the inner gear teeth 21, thus establishing a locked state. When the outer ring 42 is slid to its frontmost position, the outer gear ring 41 is completely disengaged from the inner gear teeth 21, thus establishing an unlocked state.
[0062] In one embodiment, the sliding range of the locking component 4 is defined by the rear edge of the second segment 12 and the front edge of the handle 2. Since the cross-sectional dimension of the first segment 11 is smaller than the cross-sectional dimension 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 backward to its maximum extent, the connection point 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 backward.
[0063] In one embodiment, such as Figure 1 As shown, the housing 1 has a direction indicator on its outer surface to indicate the rotation direction for locking or unlocking.
[0064] like Figure 5 and Figure 9 As shown, in one embodiment, the locking assembly 4 further includes a washer 43 mounted on the first segment 11. The washer 43 is located between the outer toothed ring 41 and the first segment 11, and its outer wall is in sliding contact with the inner wall of the outer toothed ring 41.
[0065] Two washers 43 can be mounted above the first segment 11, located at the front and rear ends of the ridge protrusion, respectively. The outer surface of the washer 43 is flush with the bottom surface of the ridge protrusion. This configuration ensures alignment between the washer 43 and the ridge protrusion and allows the external toothed ring 41 to move smoothly.
[0066] Container openers offer a versatile and user-friendly solution for opening containers of various sizes. Their adjustment mechanisms, locking components, and ergonomic design represent a significant improvement over traditional container openers.
[0067] A method of operating a container opener includes:
[0068] (a) Slide the locking assembly 4 to disengage the outer gear ring 41 from the inner gear tooth 21;
[0069] (b) Rotating the handle 2 drives the threaded rod 31 to rotate, 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 out of the housing 1, and thus adjusting the accommodating space;
[0070] (c) Insert the lid into the receiving space formed by the protrusion of the strip 33 and the arcuate surface, or move the container opener to allow the lid to pass through the receiving space;
[0071] (d) Rotate handle 2 to establish a tight contact between strip 33, friction part 14 and cover;
[0072] (e) Slide the locking assembly 4 to engage the outer gear ring 41 with the inner gear tooth 21, thereby locking the position of the handle 2 and maintaining the positional stability of the strip 33;
[0073] (f) Rotate the entire container opener so that the container opener, carrying the lid, rotates relative to the container; or, simultaneously rotate the entire container opener and the container in opposite directions to open the lid.
[0074] In some applications, container openers can also be used as tools to tighten lids onto containers.
[0075] The container opener utilizes the lever principle to transfer the force applied to the lid to the opener. The contact point between the lid and the container opening serves as the fulcrum of the lever, and the handle 2 is the other end of the lever. When force is applied to the handle 2 from a position away from the fulcrum, the lid can be opened or closed with less force.
[0076] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
