Description

Technical Field

[0001] This application belongs to the field of household appliance technology, and in particular relates to a composite dental floss body and dental floss. Background Technology

[0002] Currently, dental floss is a common household item, available in various forms such as floss picks or floss rolls. Conventional dental floss requires inserting it into the gaps between teeth and repeatedly pulling it back and forth to remove food debris. To enhance its food-removing ability, dental floss has a relatively high surface friction, which effectively removes food. However, when inserted into narrower interdental spaces, the floss can easily become stuck or even break during use, resulting in a poor user experience. Therefore, designing a technology to improve the user experience of dental floss is the technical problem this application aims to solve. Summary of the Invention

[0003] This application provides a composite dental floss body and dental floss that reduces floss breakage and improves user experience while meeting the needs of tooth removal.

[0004] To achieve the above technical objectives, this application adopts the following technical solution: In one aspect, this application provides a composite dental floss body, comprising: A linear support body, wherein the cross-section of the linear support body is non-circular; An outer protective elastic layer is provided, which wraps around the outside of the linear support.

[0005] Compared with the prior art, the advantages and positive effects of this application are: by setting the cross-section of the linear support to a non-circular design and setting an outer protective elastic layer on the outside of the linear support, the non-circular cross-section can have a larger gap after the linear support is arranged side by side to meet the requirements of dental floss compression deformation. Furthermore, the outer protective elastic layer can rely on its own elasticity to further meet the requirements of larger elastic deformation, so as to ensure that the dental floss can be smoothly inserted into narrower interdental spaces to reduce dental floss breakage. This achieves the goal of reducing dental floss breakage while meeting the needs of tooth picking, thereby improving the user experience.

[0006] Furthermore, the cross-section of the linear support is elliptical.

[0007] Furthermore, the composite dental floss body includes multiple linear support bodies, which are staggered and stacked together. Multiple linear supports are wrapped by the outer protective elastic layer.

[0008] Furthermore, along the length direction of the ellipse, the ends of two adjacent linear supports form a first gap; Along the width direction of the ellipse, the ends of two adjacent linear supports form a second gap; The first interval and the second interval form an overlapping area.

[0009] Furthermore, the outer periphery of the linear support body has multiple protruding rib structures.

[0010] Furthermore, the cross-section of the linear support is triangular.

[0011] Furthermore, the composite dental floss body includes multiple linear supports, wherein the rib structure of one linear support is located between two adjacent rib structures of another linear support; Multiple linear supports are wrapped by the outer protective elastic layer.

[0012] Furthermore, an adhesive is provided between the outer protective elastic layer and the linear support.

[0013] Furthermore, the linear support is made of PET or PA material; The outer protective elastic layer is made of TPU or TPEE material.

[0014] In another embodiment of this application, a dental floss is also provided, comprising: a plurality of the above-described composite dental floss bodies, wherein the plurality of composite dental floss bodies are connected together. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] like Figure 1 As shown, this application provides a composite dental floss body, comprising: A linear support body, wherein the cross-section of the linear support body is non-circular; An outer protective elastic layer is provided, which wraps around the outside of the linear support.

[0020] Specifically, the composite dental floss uses a linear support as the main support, which is wrapped by an outer protective elastic layer. This outer protective elastic layer has good elastic deformation ability, and after the outer protective elastic layer is wrapped around the linear support, the cross-section of the outer contour of the outer protective elastic layer matches the cross-section of the linear support. In this way, during the floss preparation process, the dental floss formed by multiple composite dental flosses arranged side by side has better elastic compression space to ensure that the dental floss is smoothly pressed into the interdental space. Furthermore, the elasticity of the outer protective elastic layer can also ensure the elastic recovery of the composite dental floss to ensure that the dental floss has a good tooth-cleaning effect.

[0021] The linear support is made of PET or PA material; the outer protective elastic layer is made of TPU or TPEE material. The linear support and the outer protective elastic layer are processed by extrusion and assembled as a single unit. The structural design of the extrusion die is not limited or described in detail here.

[0022] Compared with the prior art, the advantages and positive effects of this application are: by setting the cross-section of the linear support to a non-circular design and setting an outer protective elastic layer on the outside of the linear support, the non-circular cross-section can have a larger gap after the linear support is arranged side by side to meet the requirements of dental floss compression deformation. Furthermore, the outer protective elastic layer can rely on its own elasticity to further meet the requirements of larger elastic deformation, so as to ensure that the dental floss can be smoothly inserted into narrower interdental spaces to reduce dental floss breakage. This achieves the goal of reducing dental floss breakage while meeting the needs of tooth picking, thereby improving the user experience.

[0023] Furthermore, such as Figure 1 As shown, the cross-section of the linear support is elliptical.

[0024] Specifically, the cross-section of the linear support is elliptical, and the composite dental floss body includes multiple linear supports, which are staggered and stacked together; the multiple linear supports are wrapped by the outer protective elastic layer.

[0025] Multiple linear supports are arranged and wrapped with an outer protective elastic layer. Thus, inside the outer protective elastic layer, the multiple linear supports have an elliptical cross-section, which gives the composite dental floss a large elastic deformation as a whole.

[0026] Preferably, along the length direction of the ellipse, the ends of two adjacent linear supports form a first gap; along the width direction of the ellipse, the ends of two adjacent linear supports form a second gap; the first gap and the second gap form an overlapping area.

[0027] Specifically, to ensure that the multiple linear supports can effectively move relative to each other within the outer protective elastic layer after the composite dental floss is compressed, thereby improving its elastic deformation capability, the aforementioned staggered arrangement allows for effective displacement along the elliptical length direction, making it easier for the floss to deform and fit into the gaps between teeth.

[0028] Furthermore, such as Figure 3 As shown, the outer periphery of the linear support body forms multiple protruding rib structures 11.

[0029] Specifically, multiple rib structures 11 are formed on the outer periphery of the linear support body, so that the distance between two adjacent linear supports body is supported by the rib structures 11 to maintain a sufficient distance.

[0030] For example, the cross-section of a linear support is triangular.

[0031] Furthermore, the composite dental floss body includes multiple linear supports, wherein the rib structure 11 of one linear support is located between two adjacent rib structures 11 of another linear support; Multiple linear supports are wrapped by the outer protective elastic layer.

[0032] Specifically, multiple linear supports are arranged and wrapped with an outer protective elastic layer. Inside the outer protective elastic layer, the multiple linear supports are supported by a rib structure 11. When compressed, the adjacent linear supports have sufficient gaps so that the composite dental floss body as a whole has a large elastic deformation.

[0033] Furthermore, such as Figure 1 As shown, an adhesive 3 is also provided between the outer protective elastic layer and the linear support.

[0034] Specifically, the outer protective elastic layer and the linear support are effectively connected together by an adhesive 3. The adhesive 3 is made of an elastic colloidal material to meet the requirement that the composite dental floss has a large elastic deformation. During the extrusion process of the linear support and the outer protective elastic layer, the adhesive 3 is injected between the two.

[0035] In another embodiment of this application, a dental floss is also provided, comprising: a plurality of the above-described composite dental floss bodies, wherein the plurality of composite dental floss bodies are connected together.

[0036] Specifically, in the process of flossing, multiple composite floss bodies are arranged side by side to form floss. The specific structural form of floss can be floss sticks or floss rolls.
