Description

elastic member The present disclosure relates to an elastic member, and more specifically, to an elastic member made of a non-metallic material that can be placed inside a pump dispenser, etc., to provide a uniform elastic restoring force similar to the spring function of an existing metal material, and can distribute a load when compressed, thereby mitigating whitening phenomenon and maintaining elastic restoring force. In general, a pump dispenser is a device that uses pressurized gas, liquid, or other contents filled inside a sealed container to dispense a certain amount of the contents. It is applied to various sealed containers that store cosmetics, perfumes, medicines, and food. When a user applies an external force to the pump dispenser, the contents inside the container coupled to the pump dispenser may be discharged externally. Meanwhile, the pump dispenser is equipped with a spring so that when the user's external force is released, the deformed pump dispenser can be restored to its initial state. However, the spring is made of metal. Therefore, if the pump is to be recycled, the metal spring within the pump must be separated. However, the complex structure of the pump makes it difficult for users to separate the metal spring within the pump. [Prior Art Literature] [Patent Document] (Patent Document 0001) Republic of Korea Publication Patent No. 10-2000-0019520 (Published on April 15, 2000) The present disclosure aims to solve the aforementioned problems and other problems.

However, the present disclosure is not limited to the embodiments disclosed below and may be implemented in various other forms. These specific embodiments are provided solely to fully inform those skilled in the art of the present disclosure of the scope of the present disclosure, and the present disclosure is defined solely by the scope of the claims. Therefore, such definitions should be based on the overall content of the present disclosure. Referring to FIGS. 1 to 6, the elastic member (100) according to the embodiment of the present disclosure may be placed in various devices requiring elastic restoring force. For example, it may be placed inside a pump dispenser applied to a cosmetic container, etc., and when the head of the pump dispenser is pressed to pump the contents inside the container, it may provide elastic restoring force so that the head of the pump dispenser returns to its original state. Additionally, the elastic member (100) according to the embodiment of the present disclosure may be formed of a non-metallic material having elastic restoring force that can be compressed or stretched. Here, the elastic member (100) may be formed of one of a plastic material, a rubber material, or a thermoplastic elastomer. The plastic material may include at least one of PP (polypropylene), PE (polyethylene), EVA (ethylene-vinyl acetate copolymer), PVC (polyvinyl chloride), and PU (polyurethane), but is not limited thereto. The rubber material is a chemically cross-linked polymer and may include at least one of natural rubber and synthetic rubber. Here, the synthetic rubber may include, but is not limited to, styrene-butadiene rubber. Thermoplastic elastomers can be molded like plastics that become flexible at high temperatures, and can be polymer materials that exhibit the properties of rubber elastomers at room temperature. Therefore, the elastic member (100) can have resilience by using a thermoplastic elastomer that exhibits the properties of rubber elastomers at room temperature. Specifically, a thermoplastic elastomer is a polymer material that exhibits rubber elasticity under service conditions and can be molded like a thermoplastic plastic under certain molding conditions. However, the present invention is not limited thereto. Thermoplastic elastomers can be classified into styrene-based (thermoplastic styrenic block copolymer, SBC), olefin-based (thermoplastic olefinic elastomer, TPO), urethane-based (thermoplastic polyurethane, TPU), amide-based (thermoplastic polyamide, TPAE), and polyester-based (thermoplastic polyester elastomer, TPEE) depending on the materials used. However, the present invention is not limited thereto. According to some embodiments of the present disclosure, an elastomer made of polypropylene (PP) can provide the most appropriate elastic restoring force. Referring to FIGS. 1 to 6, an elastic member (100) according to an embodiment of the present disclosure may include an upper end ring (115), a lower end ring (117), a plurality of connecting rings (110), an elastic reinforcing member (120), and a load distributing member (130). However, the above-described components are not essential for implementing the elastic member (100), and the elastic member (100) may have more or fewer components than the components listed above. Additionally, in the embodiment of the present disclosure, the upper end ring (115), the lower end ring (117), the plurality of connecting rings (110), and the elastic reinforcing member (120) can be integrally injection-molded. Referring to FIGS. 1 and 2, the upper end ring (115) may be a ring-shaped plate and may be placed on the upper end of the elastic member (100). The lower end ring (117) may be a ring-shaped plate and may be placed at the lower end of the elastic member (100). The lower end ring (117) may have the same size and shape as the upper end ring (115). A plurality of connecting links (110) can be connected in a zigzag pattern to provide elastic restoring force that is compressed or stretched. According to an embodiment of the present disclosure, the connecting ring (110) may be a ring-shaped plate and may be placed between the upper end ring (115) and the lower end ring (117). In this case, a plurality of connecting rings (110) may be stacked and connected to each other in a zigzag manner at an angle. Additionally, the connecting ring (110) may have the same size and shape as the upper end ring (115) and the lower end ring (117). In addition, a through hole (119) may be formed in the central portion of the upper end ring (115), the lower end ring (117), and the plurality of connecting rings (110). Although not shown in the drawing, when the elastic member (100) is mounted on a pump dispenser, a tube for ejecting contents contained in a container among the components of the pump dispenser can be inserted into the through hole (119). In addition, when the elastic member (100) is used in another device, the elastic member (100) can be configured in an overall shape similar to a coil spring by forming the through hole (119) in the elastic member (100). A plurality of connecting rings (110) can be connected between their respective ends so that adjacent continuous connecting rings form an incline with respect to each other. At this time, as illustrated in FIG. 4, adjacent continuous connecting rings can be alternately connected on one side of the elastic member (100) in the width direction (X) and the other side of the elastic member (100) in the width direction (X). If the ring connected to the upper part of the elastic reinforcement part (120) among the plurality of connecting rings (110) is designated as the first ring (111), and the ring connected to the lower part of the elastic reinforcement part (120) is designated as the second ring (113), the first and second rings (111, 113) constituting the plurality of connecting rings (110) are stacked in a zigzag shape while being inclined to each other based on the width direction (X) or horizontal direction (X) of the elastic reinforcement part (120). Accordingly, a space is formed between adjacent continuous links, allowing smooth compression by external pressure. In addition, the plurality of connecting rings (110) may have the same size and shape as each other, and may also have the same size and shape as the upper end ring (115) and the lower end ring (117) as described above, which enables the plurality of connecting rings (110) to exert a constant compressive force and tensile force in the vertical direction (Z) compared to an elastic body each composed of different sizes and shapes. This can prevent twisting of the plurality of connecting rings (110) during compression and tension, thereby providing a more stable and uniform elastic restoring force. Meanwhile, one or more elastic reinforcing members (120) may be placed between adjacent connecting links among a plurality of connecting links (110). The elastic reinforcing members (120) may connect adjacent connecting links and, at the same time, reinforce the elastic restoring force between adjacent connecting links. Specifically, each of the plurality of connecting rings (110) is connected to each other, and the portion where each of the plurality of connecting rings (110) is connected to each other may be reinforced with a material of the same material as the plurality of connecting rings (110). Here, the reinforced portion may be an elastic reinforcement portion (120). Accordingly, the portion where the plurality of connecting rings (110) are connected to each other may be thicker than other portions due to the elastic reinforcement portion (120). When an elastic reinforcing portion (120) is formed at the portion where two adjacent connecting links among a plurality of connecting links (110) are connected, the elastic restoring force between the plurality of connecting links (110) can be further increased. Meanwhile, among the plurality of connecting rings (110), any one of the connecting rings connected to the upper end ring (115) or the lower end ring (117) can also be connected to the upper end ring (115) or the lower end ring (117) through the elastic reinforcing member (120). Through this, the elastic restoring force of the elastic member (100) can be further strengthened. At this time, when the upper end ring (115) and the lower end ring (117) are formed of a non-metallic material having elastic restoring force, the pressure applied to the elastic member (100) can be partially absorbed by the upper end ring (115) and the lower end ring (117). Therefore, it is possible to prevent damage such as breakage or cracking of the configuration of the elastic member (100) (e.g., the upper end ring (115), the lower end ring (117), and the plurality of connecting rings (110)) due to excessive external pressure. Here, referring to FIG. 4, the thickness (L1) and length (H1) of the elastic reinforcement part (120) are disclosed. In the embodiment of the present disclosure, the thickness (L1) of the elastic reinforcement part (120) may be formed to be equal to or thicker than the sum (L2+L3) of the thickness (L2) of the first ring (111) connected to the upper part of the elastic reinforcement part (120) among the plurality of connecting rings (110) and the thickness (L3) of the second ring (113) connected to the lower part of the elastic reinforcement part (120). When the thickness (L1) of the elastic reinforcement part (120) is equal to the sum (L2+L3) of the thicknesses between the first and second rings (111, 113), when the plurality of connecting rings (110) are fully compressed, the plate surfaces of the plurality of connecting rings (110) can contact each other and form a single cylindrical shape. At this time, in the case where the elastic reinforcing member (120) is intended to improve the elastic restoring force of the connecting ring (110) and increase the rigidity at the connecting portion, the thickness (L1) of the elastic reinforcing member (120) can be implemented to be thicker than the sum (L2+L3) of the thicknesses between the first and second rings (111, 113). In this case, the connection between the first and second rings (111, 113) becomes thicker, so that the time when the elastic restoring force weakens or the connection is damaged even after long-term use can be further delayed. In addition, although not shown in the drawing, the thickness of the elastic reinforcement portion (120) formed between the upper end ring (115) and the connecting ring (110) may also be formed to be the same as or thicker than the sum of the thickness of the upper end ring (115) and the thickness of the connecting ring (110) connected to the upper end ring (115). In addition, although not shown in the drawing, the thickness of the elastic reinforcement portion (120) formed between the lower end ring (117) and the connecting ring (110) may also be formed to be the same as or thicker than the sum of the thickness of the lower end ring (117) and the thickness of the connecting ring (110) connected to the lower end ring (117). Meanwhile, referring to FIGS. 3 to 6, a load distribution member (130) can be placed at a connection portion (M) where a connection ring (110) and an elastic reinforcement member (120) are connected, and can distribute a load applied to the elastic reinforcement member (120) when a plurality of connection rings (110) are compressed. In the embodiment of the present disclosure, the load distribution part (130) includes a first distribution part (131), a second distribution part (133), and a concave groove (

[0072] 135) and distributed space (136). The concave groove (135) may be formed concavely toward the inside of the elastic reinforcement member (120) at the connecting portion (M). In addition, the concave groove (135) may be arranged to cross the inside of the elastic reinforcement member (120) in the longitudinal direction (Y). In the embodiment of the present disclosure, the concave groove (135) may form a concave arch-shaped curved surface toward the inside of the elastic reinforcement member (120). The first dispersing portion (131) may be formed to be concave inwardly at the lower portion of the first ring (111) and may be arranged to cross the longitudinal direction (Y) of the first ring (111). In the embodiment of the present disclosure, the first dispersing portion (131) may be formed to have an inwardly curved surface at the lower portion of the first ring (111) and may be connected with a curvature corresponding to the upper surface (135a) of the concave groove (135). The second dispersion portion (133) may be formed to be concave inwardly on the upper portion of the second ring (113) and may be arranged to cross the longitudinal direction (Y) of the second ring (113). In the embodiment of the present disclosure, the second dispersion portion (133) may be formed to have an inwardly curved surface on the upper portion of the second ring (113) and may be connected with a curvature corresponding to the lower surface (135b) of the concave groove (135). And, the first and second distribution units (131, 133) can be arranged in positions facing each other in the vertical direction (Z). Accordingly, the concave groove (135) and the first and second dispersing portions (131, 133) can form an overall arch shape based on the width direction (X) of the elastic member (100). Referring to Fig. 6, the curved surface of the arch shape in which the concave groove (135) and the first and second dispersing portions (131, 133) are formed can be confirmed. The dispersion space (136) can be formed in the empty space where the concave groove (135) and the first and second dispersion parts (131, 133) face each other. The dispersion space (136) can provide a space where the first and second dispersion parts (131, 133) and the concave groove can be narrowed. Meanwhile, the length (G2) of the first and second distribution sections (131, 133) may be formed to be greater than the depth (G1) of the concave groove (135). In the embodiment of the present disclosure, the elastic reinforcement member (120) is not compressed or tensioned, and the first and second rings (111, 113) connected to the elastic reinforcement member (120) are compressed and tensioned, respectively. As described above, the concave groove (135) and the first and second distribution portions (131, 133) form an arch shape, and referring to FIG. 5, when a load (P1) is applied, the first and second rings (111, 113) move up and down and are compressed and stretched, so in order to further increase the effect of distributing the load (P2), the length (G2) of the first and second distribution portions (131, 133) formed in the first and second rings (111, 113) must be longer than the depth (G1) of the concave groove (135) so that the first and second distribution portions (131, 133) are deformed in the up and down direction and the load (P1) can be better distributed. In addition, referring to FIG. 4, the width direction (X) length (H1) of the elastic reinforcement part (120) and the depth (G1) of the concave groove (135) are shown. The concave groove (135) is arranged to form an arch-shaped curved surface on the inside of the elastic reinforcement part (120). At this time, the depth (G1) of the concave groove (135) can be formed to be smaller than the widthwise (X) remaining length (H2) of the elastic reinforcement part (120). Here, the widthwise (X) remaining length (H2) of the elastic reinforcement part (120) can be defined as the length obtained by subtracting the depth (G1) of the concave groove (135) from the widthwise (X) length (H1) of the elastic reinforcement part (120). As the depth (G1) of the concave groove (135) increases, the width direction (X) length of the entire load distribution section (130) connected to the first and second distribution sections (131, 133) increases, so the load (P1) can be distributed more widely from the load distribution section (130) to the load (P2). However, if the depth (G1) of the concave groove (135) is too deep, for example, if it is greater than the widthwise (X) residual length (H2) of the elastic reinforcement member (120), it may actually reduce the rigidity of the elastic reinforcement member (120). That is, when the compression and tension of the elastic member (100) occur countless times, the elastic reinforcement member (120) may crack or be cut due to wear, damage, or material deformation. Therefore, to prevent such problems, it may be desirable to form the depth (G1) of the concave groove (135) smaller than the widthwise (X) residual length (H2) of the elastic reinforcement portion (120). Hereinafter, with reference to FIG. 5, the principle of load distribution by the load distribution unit (130) according to the embodiment of the present disclosure will be explained. Referring to Fig. 5, when a load (P1) is applied to the elastic member (100), the elastic member (100) is compressed, and during compression, the first ring (111) and the second ring (113) become closer to each other. Since the first ring (111) and the second ring (113) are each connected to the elastic reinforcing member (120), when the first ring (111) and the second ring (113) become completely compressed while becoming closer to each other in the vertical direction (Z), the first ring (111) and the second ring (113) become positioned parallel to each other in the width direction (X) of the elastic member (100). When the compression and tension of the elastic member (100) are repeated countless times by a load (P1), a whitening phenomenon may occur at the connection portion (M) between the first ring (111) and the second ring (113) and the elastic reinforcement portion (120). In the embodiment of the present disclosure, the whitening phenomenon can be defined as a phenomenon in which the elastic restoring force of a specific portion of the elastic member (100) decreases as the elastic member (100) is repeatedly compressed and stretched countless times. When the load (P1) is repeatedly applied and removed, the first and second rings (111, 113) move in the up-and-down direction (Z) countless times while connected to the elastic reinforcement part (120). Accordingly, wear, damage, or material deformation may occur at the connection part (M) where the first and second rings (111, 113) and the elastic reinforcement part (120) are connected, which may reduce the elastic restoring force of the connection part (M). In particular, in the case of a non-metallic material such as PP (polypropylene) rather than a metallic material such as spring steel, wear, damage, or material deformation may occur due to a lot of compression and tension at the connection part (M) of the first and second rings (111, 113) and the elastic reinforcement part (120), which may reduce the elastic restoring force. In the embodiment of the present disclosure, by arranging a load distribution part (130) at the connection part (M) of the first and second rings (111, 113) and the elastic reinforcing part (120), the problem of the elastic restoring force being reduced as described above can be prevented and alleviated. As disclosed in FIG. 5, when a load (P1) is applied to the elastic member (100), the first ring (111) moves downward and the second ring (113) moves upward and becomes closer to each other based on the elastic reinforcing member (120). At this time, a first dispersing portion (131) is formed at the lower portion of the first ring (111), and the first dispersing portion (131) is connected to the upper surface (135a) of a concave groove (135) that extends to the inner side of the elastic reinforcing portion (120), and the first dispersing portion (131) and the concave groove (135) form a curved surface that is connected to each other. Accordingly, the lower portion of the first ring (111) and the concave groove (135) can be bent to form a smooth curved surface, and this is the principle of dispersing the load along the curved surface of the arch in the design of the arch of a building. As indicated by the arrow in Fig. 5, it can be confirmed that a portion of the load (P1) applied to the elastic member (100) is distributed as load (P2) along the curved surface of the first distribution portion (131) and the concave groove (135). In addition, a second dispersing portion (133) is formed on the upper portion of the second ring (113), and the second dispersing portion (133) is connected to the lower surface (135b) of the concave groove (135) that extends to the inner side of the elastic reinforcing portion (120), and the second dispersing portion (133) and the concave groove (135) form a curved surface that is connected to each other. Accordingly, the upper portion of the second ring (113) and the concave groove (135) can be bent to form a smooth curved surface, and this also applies the same principle of load distribution along the curved surface of the arch in the design of the arch of a building. And, based on the inner end (135c) of the concave groove (135), the concave groove (135) and the first and second distribution parts (131, 133) form an arch shape overall, so that the load (P2) is distributed as shown by the arrow, and the occurrence of whitening phenomenon at the connection part (M) of the first and second rings (111, 113) and the elastic reinforcement part (120) can be prevented and alleviated. Referring to the arrows disclosed in Fig. 5, it can be confirmed that the load (P1) applied to the elastic member (100) is distributed along a wide area in the arch-shaped curved surface of the first and second distribution portions (131, 133) and the concave groove (135). Accordingly, since the load (P1) is distributed and applied to the connecting portion (M) between the connecting link (110) and the elastic reinforcing portion (120), the whitening phenomenon at the connecting portion (M) is prevented and alleviated, and this prevents the elastic restoring force of the elastic member (100) from weakening, thereby extending the service life of the elastic member (100). In the present disclosure, the elastic member is not limited to the configuration and method of some of the embodiments described above, but some of the embodiments may be configured by selectively combining all or some of the embodiments so that various modifications can be made. Meanwhile, although the present disclosure has been described with reference to the attached drawings, these are merely examples and are not limited to specific embodiments. Various modifications that can be implemented by those skilled in the art to which the invention pertains are also within the scope of the claims. Furthermore, such modifications should not be understood separately from the technical spirit of the present invention. As described above, the elastic member according to the present invention is formed of a non-metallic material having elastic restoring force instead of a metallic material, so that the pump dispenser can be recycled without having to be disassembled separately, and the load generated during compression can be distributed, so that the whitening phenomenon can be alleviated and the elastic restoring force can be maintained, making it an invention with very high industrial applicability.
