Description

Technical Field

[0001] This utility model belongs to the field of applicator technology, and in particular relates to an applicator. Background Technology

[0002] In the field of medical devices and liquid medications, applicators are common tools used to store and dispense liquid medications (such as disinfectants, ointments, etc.). These liquids are usually sealed in fragile containers, such as ampoules or special plastic sachets, which need to be broken open to allow the liquid to wet the applicator head before use.

[0003] In the prior art, the applicator includes a shell and a handle. The handle is set on the shell, which is a relatively sealed structure. By pressing the shell with the handle, the shell is deformed and the container inside the shell is crushed. The container is generally an ampoule, which is a relatively fragile structure.

[0004] However, there are some technical problems with the existing technology that need to be solved. For example, in actual operation, a large amount of pressure is often required to break the ampoule. Utility Model Content

[0005] In view of this, the present invention provides an applicator in which the applicator head body and the applicator body are rotated by external force, which can cause the container containing the liquid to be applied to break, thereby allowing the liquid to flow into the applicator head body.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: An applicator includes an applicator head, an applicator body, and a container. The applicator head includes an applicator head body, and the container is assembled inside the applicator body and filled with a liquid to be applied. The applicator head body and the applicator body are rotatably connected. A shearing plate is provided inside the applicator head body at one end near the applicator body. An eccentric hole is provided on the shearing plate. One end of the container passes through the eccentric hole and is inserted into the applicator head body. The applicator head body is configured to rotate relative to the applicator body, the shearing blade cuts the container, one end of the container extending into the applicator head body breaks, and the liquid to be applied in the container is released.

[0007] In a preferred embodiment, the container is positioned inside the applicator body, the applicator head body is configured to rotate, and the shearing blade cuts the container.

[0008] In a preferred embodiment, the applicator body is flat.

[0009] In a preferred embodiment, the device further includes a rotation positioning structure configured to limit the rotation angle of the applicator head body and lock the applicator head body.

[0010] In a preferred embodiment, the rotary positioning structure includes a first limiting plate, a second limiting plate, a positioning rib, and a limiting post. The first limiting plate, the second limiting plate, and the positioning rib are all disposed on the shearing plate, and the limiting post is disposed on the inner wall of the applicator body. The limiting post rotates within the arc range defined by the first limiting plate and the second limiting plate, and the corresponding positioning rib forms a first groove with the first limiting plate. The limiting post is embedded in the first groove to position the applicator head body.

[0011] In a preferred embodiment, the applicator head body is snap-fitted to the applicator body.

[0012] In a preferred embodiment, a sealing structure is provided between the applicator head body and the applicator body.

[0013] In a preferred embodiment, the end of the applicator body near the applicator head body is press-fitted with the applicator head body.

[0014] In a preferred embodiment, the end of the applicator body away from the applicator head body is provided with an exhaust hole.

[0015] In a preferred embodiment, the applicator head further includes an applicator material, which is fixed to the applicator head body.

[0016] In a preferred embodiment, the coating material is an elastomer with pores.

[0017] In a preferred embodiment, the plane containing the application material is set at an angle to the axis of the applicator body.

[0018] Because of the adoption of the above technical solution, this utility model has the following advantages and positive effects compared with the prior art: The applicator provided by this utility model includes an applicator head, an applicator body, and a container. The applicator head includes an applicator head body, which is rotatably connected to the applicator body. A shearing blade is provided at one end of the applicator head body near the applicator body. An eccentric hole is formed on the shearing blade, where the center of the eccentric hole is not collinear with the center of the shearing blade. One end of the container extends into the applicator head body through the eccentric hole, causing the applicator head body and the applicator body to rotate relative to each other. This causes the shearing blade to cut the container, breaking the end of the container that extends into the applicator head body, allowing the liquid to be applied inside the container to flow out and then wet the applicator head for application. In other words, with this utility model, the operator can use the applicator to apply liquid by rotating the applicator head or the applicator body, making the operation simpler and requiring only a small and continuous torque to break the bottle, thus saving a lot of effort.

Detailed Implementation

[0021] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more comprehensive understanding of the applicator proposed in this invention. The advantages and features of this invention will become clearer from the following description.

[0022] In the prior art, the applicator includes a shell and a handle. The handle is set on the shell, which is a relatively sealed structure. By pressing the shell with the handle, the shell is deformed and the container inside the shell is crushed. The container is generally an ampoule, which is a relatively fragile structure.

[0023] However, some technical problems in the existing technology urgently need to be solved. For example, in actual operation, a large amount of pressing force is often required to crush the ampoule. There are attempts to solve this technical problem through other means, such as Chinese patent CN119565011A, which uses a vertical pressing bottle-breaking structure. This applicator includes a shell forming a container cavity and a pressing structure disposed on the shell. In use, the user applies a vertical downward pressing force to the pressing structure, causing the crushing element to pass through the pressing hole on the shell and act directly on the container surface, releasing the internal liquid by crushing or puncturing the container. However, the bottle-breaking mechanism in this patent relies on the vertical pressing force applied by the user to directly overcome the overall structural strength of the container. Although some designs use a lever structure to save effort, the user still needs to provide a large instantaneous burst of force. For users with insufficient hand strength (such as the elderly, injured persons, or medical personnel who are prone to fatigue from long-term operation), operation remains inconvenient and strenuous.

[0024] Please refer to Figures 1-7 This embodiment provides an applicator that can solve the above-mentioned technical problems. The applicator of this application will be described in detail below.

[0025] The applicator includes an applicator head 1, an applicator body 2, and a container 3. The applicator head 1 includes an applicator head body 101 and an applicator material 102. The applicator material 102 is a material that absorbs liquid and applies it to the patient. The applicator material 102 is a porous elastomer, such as a sponge or other plastic elastomer. The applicator material 102 can be ultrasonically welded to the applicator head body 101, or glued to the applicator head body 101, or bonded to the applicator head body 101 by two-color injection molding. The applicator body 2 has a cavity for accommodating the container 3. The container 3 is assembled in the cavity. The applicator body 2 can be equipped with one, two, or more containers 3, without any limitation. The container 3 is filled with the liquid to be applied. The applicator head body 101 is rotatably connected to the applicator body 2. A shearing plate 4 is provided inside the applicator head body 101 near the applicator body 2. An eccentric hole 5 is provided on the shearing plate 4. One end of the container 3 passes through the eccentric hole 5 and is inserted into the applicator head body 101. The applicator head body 101 is configured to rotate relative to the applicator body 2. The shearing blade 4 cuts the container 3, and the end of the container 3 that extends into the applicator head body 101 is broken, releasing the liquid to be applied from the container 3.

[0026] In this embodiment, the applicator uses rotational torque and an eccentric hole 5 to shear and break the container 3, releasing the liquid to be applied. The operator only needs to rotate the applicator head 101 and the applicator body 2 relative to each other to break the container 3. Therefore, only a small and continuous torque is needed to break the bottle, making it very labor-saving, especially suitable for users with insufficient hand strength, and the operation is also very simple. The rotational action is also relatively smooth and controllable. The break in the container 3 is a regular cut formed by shearing force, effectively preventing the container 3 (especially glass ampoules) from suddenly bursting due to uneven pressure, greatly reducing the risk of glass shards flying and the generation of small fragments.

[0027] Container 3 is typically an ampoule, a relatively fragile structure that can be broken using rotational shearing force, allowing the liquid inside to be released. Alternatively, container 3 can be a plastic bottle, with the location of the eccentric hole 5 designed for easy shearing or breaking.

[0028] In this embodiment, the applicator head body 101 and the applicator body 2 rotate relative to each other, and the container 3 can release the liquid to be applied. This can be achieved by either rotating the applicator head body 101 or rotating the applicator body 2.

[0029] In this embodiment, the applicator head body 101 rotates while the applicator body 2 remains stationary. Simultaneously, the container 3 is positioned inside the applicator body 2. Rotating the applicator head body 101 causes the shearing blade 4 to cut the container 3, resulting in damage to the container 3 inside the applicator head body 101. In this embodiment, the applicator body 2 is flat, but near the end of the applicator head body 101, it becomes cylindrical. The flat and cylindrical shapes are seamlessly connected, and the cylindrical portion of the applicator body 2 is rotatably connected to the applicator head body 101. Two containers 3 are assembled within the cavity inside the applicator body 2. The shape of the applicator body 2 itself allows for the positioning of the containers 3. When the applicator head body 101 rotates, the shearing blade 4 cuts the containers 3.

[0030] In one preferred embodiment of this invention, a rotation positioning structure 6 is further included. The rotation positioning structure 6 is configured to limit the rotation angle of the applicator head body 101 and lock the applicator head body 101, thereby preventing the applicator from rotating during applicator application.

[0031] Furthermore, the rotary positioning structure 6 includes a first limiting plate 601, a second limiting plate 602, a positioning rib 603, and a limiting post 604. The first limiting plate 601, the second limiting plate 602, and the positioning rib 603 are all disposed on the shearing plate 4, and the limiting post 604 is disposed on the inner wall of the applicator body 2. The limiting post 604 rotates within the arc range defined by the first limiting plate 601 and the second limiting plate 602, and the corresponding positioning rib 603 forms a first groove 605 with the first limiting plate 601. The limiting post 604 is embedded in the first groove 605 to position the applicator head body 101.

[0032] In this embodiment, the operator needs to rotate the applicator head body 101 so that the limiting post 604 passes over the positioning rib 603, thereby rotating towards the second limiting plate 602. The shearing plate cuts and breaks the container 3, releasing the liquid to be applied inside the container 3. The second limiting plate 602 restricts the applicator head body 101 from continuing to rotate. At this time, the applicator head body 101 is rotated back to the starting point, so that the limiting post 604 is embedded in the first groove 605 to position the applicator head body 101. Thus, when there is no external force to rotate the applicator head body 101, the applicator head body 101 will not rotate. Therefore, during the applicator application process, when there is no external force to rotate the applicator head body 101, the applicator head body 101 will not rotate on its own.

[0033] Preferably, the applicator head body 101 is snap-fitted to the applicator body 2. For specific implementation, see [link to relevant documentation]. Figures 5-6 The applicator head body 101 extends toward the applicator body 2 and has an extension body 8. The extension body 8 has a second groove 10 on the side near the applicator body 2. The applicator body 2 has a protrusion 9 on the side near the extension body 8. The protrusion 9 is embedded in the second groove 10 to form a snap-fit ​​connection.

[0034] Preferably, a sealing structure 7 is provided between the applicator head body 101 and the applicator body 2. The sealing structure 7 can be a sealing ring or something else. Figures 5-6 As shown, the cylindrical part of the applicator body 2 is press-fitted with the extension 8 of the applicator head body 101 to form a sealing structure 7.

[0035] Preferably, the end of the applicator body 2 away from the applicator head body 101 is provided with an exhaust hole 11, which facilitates the outflow of the liquid to be applied.

[0036] Preferably, the plane containing the application material 102 is set at an angle to the axis of the applicator body 2 to facilitate the application operation.

[0037] The applicator in this embodiment can be used not only for medical disinfection or medicine, but also for applying cosmetics.

Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
