Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to an adjustable multi-purpose lid opener. Background Technology

[0002] In the daily operations of industries such as medical care, food processing, and drug development, it is often necessary to open bottles of various sizes and materials, such as aluminum-capped injection bottles and oral liquid bottles, tin-capped excipient containers, and glass ampoules. Especially in the research, development, production, and clinical use of ADCs (Antibody-Drug Conjugates) and small molecule drugs, multiple packaging forms are involved. Ampoules are used to store highly active cytotoxic toxins (payloads), linkers, small molecule drug formulations, or reference standards; aluminum-capped injection bottles and aluminum-capped vials are used to seal finished injectable ADCs or small molecule drugs; aluminum-capped oral liquid bottles are used for sealing oral solutions; and tin-capped excipient containers are used for the storage and transportation of large volumes of excipients (such as sucrose and trehalose).

[0003] In the existing technology, traditional cap-opening tools have a single function. In order to deal with various medicine bottles with different packaging forms, staff often need to prepare a variety of different cap-opening tools (such as ampoule cutters, aluminum cap pliers, and sheet metal pry bars). In addition, traditional aluminum cap pliers are usually only suitable for a single size and cannot be compatible with caps of different diameters (such as 10mm~32mm). The existence of these defects leads to the need for operators to repeatedly switch operating tools during the work process, which is inconvenient and seriously affects work efficiency. At the same time, the management and storage of multiple tools will also increase management costs.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable multi-purpose cap opener to solve the problems of traditional cap opener tools having limited functionality, affecting work efficiency and management costs.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: an adjustable multi-purpose lid opener, including a fixed handle, a lid opening component, and a cutting component. The lid opening component includes a fixed claw and a movable claw. The fixed claw and the cutting component are respectively installed at both ends of the axial direction of the fixed handle. The movable claw is installed on the fixed handle. The movable claw can be limited to slide along the axial direction of the fixed handle to approach or move away from the fixed claw. The end of the fixed claw is bent towards the movable claw to form a hook.

[0007] The cutting assembly includes a fixed back plate and a cutting component. The fixed back plate is mounted on a fixed handle and has a bottle-penetrating hole. The cutting component includes a cutting blade, which is mounted on the fixed back plate and located near the bottle-penetrating hole. The cutting blade can be driven to swing in a single degree of freedom to move closer to or away from the bottle-penetrating hole.

[0008] Furthermore, it also includes a sliding assembly, which includes a slide block and a connecting strip. The slide block is connected to the movable claw through the connecting strip. The fixed handle is provided with an inner sliding groove along the axial direction. The slide block can be slidably mounted in the sliding groove, and the movable claw slides along the axial direction with a single degree of freedom.

[0009] Furthermore, it also includes a locking component, which includes a limiting tooth, a locking boss, and a limiting arm. The top surface of the fixed handle is recessed inward to form a limiting groove that communicates with the inner sliding groove. The limiting groove is provided with multiple limiting teeth along the axial direction. The limiting arm is made of elastic material and is fixedly installed on the slide block and located in the limiting groove. The end of the limiting arm is provided with a limiting flange. The locking boss is slidably installed on the slide block and located in the limiting groove. The locking boss can be driven to slide to the end of the limiting arm and limit the slide block axially with any of the limiting teeth.

[0010] Furthermore, the sliding assembly also includes a sliding cover plate, and the locking assembly also includes a locking cover plate and a strip. The sliding cover plate is installed on the top surface of the slide block, and the longitudinal gap between the sliding cover plate and the slide block forms an installation track. The strip is integrally formed on the axial end of the locking cover plate, and the locking boss is integrally formed on the bottom surface of the locking cover plate. The strip is slidably installed on the installation track.

[0011] Furthermore, the cutting component also includes a tool mounting bracket, which is hinged to the fixed back plate and has a tool mounting slot, in which the cutting blade is detachably mounted.

[0012] Furthermore, the cutting component also includes an elastic separator with elastic force, a baffle is provided on the fixed back plate, the elastic separator is installed on the tool mounting bracket, and the two ends of the elastic separator along its own elastic force direction respectively abut against the tool mounting bracket and the baffle, so that the tool mounting bracket is moved away from the bottle hole under the action of the elastic force of the elastic separator.

[0013] Furthermore, there are two cutting components, which are symmetrically arranged on both sides of the bottle hole, with the axis of symmetry being the central axis of the fixed handle.

[0014] Furthermore, the cutting assembly also includes a cutting cover plate, which is installed on the cutting back plate and covers the cutting blades of the two cutting components. The cutting cover plate has a clearance hole at the position corresponding to the bottle penetration hole.

[0015] Furthermore, the limiting arm is provided with two symmetrical ones, the locking boss is located between the two limiting arms, and multiple limiting teeth are symmetrically arranged on both sides of the limiting slide. The axis of symmetry of the limiting arm and the limiting teeth are both the central axis of the fixed handle.

[0016] The working principle of this technical solution is as follows:

[0017] (1) When opening the cover, first adjust the movable claw so that the fixed claw and the movable claw abut against the two sides of the aluminum cover respectively, and after the hook is engaged with the lower edge of the aluminum cover, lock the movable claw to the limit, and swing the fixed handle to pry open the aluminum cover.

[0018] (2) When opening an ampoule, pass the ampoule through the through hole, push the cutter against the cut position of the ampoule, then rotate the ampoule. After the cutter makes a cut, release the cutter and swing the cap opener. The cap opener forms a lever at the cut position of the ampoule and pry the ampoule open.

[0019] The beneficial effects of this technical solution are as follows:

[0020] Compared to existing technologies, this adjustable multi-purpose cap opener achieves cap opening through the cooperation of a fixed claw and a movable claw. The sliding mechanism of the movable claw allows for flexible adjustment of the distance between the two claws, better accommodating caps of various sizes and significantly improving the tool's versatility and efficiency. The fixed handle also integrates a cutting component, using a swing-mounted cutting blade to cut ampoules. The fixed handle, together with a fixed back plate with a through-hole, forms a lever at the cut point of the ampoule, allowing for direct opening without direct contact with the cutting area, greatly reducing the risk of finger cuts and improving operational safety.

[0021] This utility model discloses an adjustable multi-purpose cap opener that integrates cap opening and ampoule cutting functions into one compact and easy-to-operate device. The multi-functional integration and adjustable design ensure that operators do not need to frequently change tools, allowing them to perform multiple operations on the same tool, thus improving work efficiency. It is also easy to carry and store, effectively reducing management costs. Attached Figure Description

[0029] The reference numerals in the accompanying drawings include: fixed handle 1, inner slide groove 101, limiting slide groove 102, fixed claw 2, hook 201, movable claw 3, sliding cover plate 4, locking cover plate 5, connecting strip 6, limiting tooth 7, tool mounting bracket 8, cutting cover plate 9, clearance hole 10, slide block 11, limiting arm 12, locking boss 13, insert strip 14, mounting slide 15, fixed back plate 16, cutting blade 17, bottle through hole 18, baffle 19, elastic separator 20, tool mounting groove 21, limiting flange 22.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The basic implementation examples are as follows: Figure 1-6As shown: An adjustable multi-purpose cap opener includes a fixed handle, a cap opening assembly, and a cutting assembly. The cap opening assembly includes a fixed claw 2 and a movable claw 3. The fixed claw 2 and the cutting assembly are respectively installed at both ends of the fixed handle along the axial direction. The movable claw 3 is installed on the fixed handle and can be limited to slide along the axial direction of the fixed handle to approach or move away from the fixed claw 2. The end of the fixed claw 2 is bent towards the movable claw 3 to form a hook 201. The cutting assembly includes a fixed back plate 16 and a cutting member. The fixed back plate 16 is installed on the fixed handle and is provided with a bottle through hole 18. The cutting member includes a cutting blade 17, which is installed on the fixed back plate 16 and located near the bottle through hole 18. The cutting blade 17 can be driven to swing with a single degree of freedom to approach or move away from the bottle through hole 18. The movable claw 3 can be configured in several ways. It can slide back and forth between the fixed claw 2 and the cutting component with a single degree of freedom, or it can be slidably mounted on the fixed handle 1 via other connecting components and slide outside the fixed claw 2. As the movable claw 3 slides, the distance between the two claws can be flexibly adjusted to accommodate caps of different sizes, ensuring the cap-opening function and expanding its application range. Whether it's an aluminum cap for a vial or a metal cap for an auxiliary material container, it can be opened. In use, first adjust the distance between the two claws, then hold each claw against the sides of the cap, and engage the hook 201 with the lower edge of the cap to pry it open. The cutting component allows the cap opener to open ampoules, and when opening ampoules, the cap opener can be used without requiring manual prying, saving time and effort, and effectively improving safety.

[0032] In this embodiment, a sliding assembly is also included. The sliding assembly includes a slide block 11 and a connecting strip 6. The slide block 11 is connected to the movable claw 3 through the connecting strip 6. The fixed handle is provided with an inner sliding groove 101 along the axial direction. The slide block 11 can be slidably mounted in the sliding groove, and the movable claw 3 slides along the axial direction with a single degree of freedom. Specifically, the sliding of the movable claw 3 is achieved through the sliding assembly. In this embodiment, the inner sliding groove 101 is axially through-type. The fixed claw 2 is integrally formed on one end of the fixed handle 1, and the fixed back plate 16 is installed on the other end of the fixed handle 1. The movable claw 3 is integrally formed on one end of the connecting strip 6, and the slide block 11 is fixedly mounted on the other end. The slide block 11 is slidably inserted into the inner sliding groove 101 from the side of the fixed handle 1 where the fixed claw 2 is mounted. The slide block 11 is driven to slide in the sliding groove, and the movable claw 3 slides accordingly, thereby realizing the adjustment of the distance between the two claws. At the same time, the cutting assembly also limits the slide block 11 in the axial direction to prevent it from sliding excessively.

[0033] In this embodiment, a locking component is also included. The locking component includes a limiting tooth 7, a locking boss 13, and a limiting arm 12. The top surface of the fixed handle 1 is recessed inward to form a limiting groove 102 that communicates with the inner sliding groove 101. The limiting groove 102 is provided with a plurality of limiting teeth 7 along the axial direction. The limiting arm 12 is made of elastic material. The limiting arm 12 is fixedly installed on the slide block 11 and located in the limiting groove 102. The end of the limiting arm 12 is provided with a limiting flange 22. The locking boss 13 is slidably installed on the slide block 11 and located in the limiting groove 102. The locking boss 13 can be driven to slide to the end of the limiting arm 12 and limit the slide block 11 in the axial direction with any of the limiting teeth 7. To ensure stable operation of the opening mechanism, a locking component is provided. This component locks the slide block 11 after adjusting the gap between the two claws. In this embodiment, the locking limit is achieved through clamping. A limiting groove 102 is formed at the top of the inner groove 101, and a limiting tooth 7 is provided within the limiting groove 102. An elastic limiting arm 12 is integrally formed on the slide block 11. When the slide block 11 is pushed, the limiting flange 22 of the limiting arm 12 is squeezed by the limiting tooth 7, causing it to deform inward (towards the central axis of the fixed handle 1) to avoid the limiting arm 12. To lock the slide block 11, simply slide the locking boss 13. When the locking boss 13 slides to the position near the limiting flange 22 at the end of the limiting arm 12, it will not deform inward regardless of how the limiting flange 22 is squeezed. That is, the limiting tooth 7 and the locking boss 13 clamp and limit the limiting arm 12, thereby locking the slide block 11. Figure 5 As shown. In this embodiment, sliding installation refers to the fact that the component can still be driven to slide independently relative to the mounting base after installation. Of course, since the component is mounted on the mounting base, it can also move synchronously with the mounting base, which is understandable to those skilled in the art and will not be elaborated here.

[0034] In this embodiment, the sliding assembly further includes a sliding cover plate 4, and the locking assembly further includes a locking cover plate 5 and an insert 14. The sliding cover plate 4 is installed on the top surface of the slide block 11, and the longitudinal gap between the sliding cover plate 4 and the slide block 11 forms an installation slide 15. The insert 14 is integrally formed at the axial end of the locking cover plate 5, and the locking boss 13 is integrally formed on the bottom surface of the locking cover plate 5. The insert 14 is slidably installed in the installation slide 15. In this embodiment, for ease of operation, a sliding cover plate 4 and a locking cover plate 5 are provided. Both the sliding cover plate 4 and the locking cover plate 5 are sloping structures with a high center and low sides in the axial direction. The sliding cover plate 4 passes through the limiting slide groove 102 from top to bottom and connects to the top surface of the slide block 11. The gap between the bottom surface of the sliding cover plate 4 and the top surface of the slide block 11 forms an installation slide 15, and the insert 14 is slidably inserted into the installation slide 15 to realize the sliding installation of the locking boss 13 on the slide block 11. In this embodiment, the insert 14 is designed as two separate parts. This design ensures lightweighting while allowing for sliding installation.

[0035] In this embodiment, the cutting component also includes a tool mounting bracket 8, which is hinged to a fixed back plate. The tool mounting bracket 8 is provided with a tool mounting groove 21, in which the cutting blade 17 is detachably mounted. In this embodiment, the cutting blade 17 is an ampoule cutting abrasive wheel. The cutting blade 17 is mounted in the tool mounting bracket 8 by clamping it with fasteners. Compared to the traditional direct operation of the cutting blade 17, this embodiment designs a tool mounting bracket 8 to mount the cutting blade 17, exposing only the cutting edge of the cutting blade 17. During use, the cutting blade 17 is driven by the tool mounting bracket 8 to hold it against the ampoule, without direct contact with the cutting blade 17, which is safer.

[0036] In this embodiment, the cutting component further includes an elastic separator 20 with elastic force. A baffle 19 is provided on the fixed back plate. The elastic separator 20 is mounted on the tool mounting bracket 8. Both ends of the elastic separator 20 along its own elastic force direction respectively abut against the tool mounting bracket 8 and the baffle 19, so that the tool mounting bracket 8 moves away from the bottle hole 18 under the action of the elastic force of the elastic separator 20. In this embodiment, two cutting components are provided, symmetrically arranged on both sides of the bottle hole 18, with the axis of symmetry being the central axis of the fixed handle. In this embodiment, the elastic separator 20 is a torsion spring. The tool mounting bracket 8 is hinged to the fixed back plate 16 via a hinge shaft. The elastic separator 20 is simultaneously sleeved on the hinge shaft. One end of the elastic separator 20 abuts against the baffle 19, and the other abuts against the inner wall of the tool mounting bracket 8. This allows the tool mounting bracket 8 to automatically move away from the bottle hole 18 under the action of elastic force. When in use, the operator squeezes the two cutting components at the same time. The cutting edges of the cutting blades 17 of the two cutting components simultaneously contact and abut against the ampoule. Compared with setting a single blade, setting two blades at the same time can reduce the rotation angle of the ampoule during cutting, resulting in higher work efficiency.

[0037] In this embodiment, the cutting assembly also includes a cutting cover plate 9, which is installed on the cutting back plate and covers the cutting blades 17 of the two cutting components. The cutting cover plate 9 has a clearance hole 10 at the position corresponding to the bottle penetration hole 18. The cutting cover plate 9 is mainly designed to cover the exposed cutting edge of the cutting blade 17 to protect the operator and avoid injury, while the clearance hole 10 is used to insert ampoules through the bottle penetration hole 18.

[0038] In this embodiment, two symmetrical limiting arms 12 are provided, and a locking boss 13 is located between the two limiting arms 12. Multiple limiting teeth 7 are symmetrically arranged on both sides of the limiting groove 102. The axis of symmetry of the limiting arms 12 and the limiting teeth 7 are both the central axis of the fixed handle 1. In this embodiment, two limiting arms 12 are provided simultaneously, and corresponding limiting teeth 7 are provided on both sides of the limiting groove 102. This forms a limiting structure on both sides of the slide block 11. Compared with a single-sided limiting structure, this double-sided symmetrical limiting structure has a better locking effect and further ensures that the moving claw 3 will not slip during the opening process.
