Description

Technical Field

[0001] The present invention relates to the field of entertainment toys, and more particularly to toy water balloons.

Background Art

[0002] As the weather gets hotter, toys using water as a medium become popular. Toys like water guns can be played with in a cool and enjoyable way. However, in the case of water guns, the water pressure is strong, making it easy to hurt people, especially the eyes. Currently, there is a water balloon fight game where water-filled balloons are thrown at opponents. The opponent who is hit is out when the water balloon breaks and they get wet. So, people try to avoid the flying water balloons as much as possible. This game is a cool, enjoyable, and safe way to beat the heat.

[0003] However, the water balloons currently used in water balloon fights are disposable balloons that cannot be reused after being broken. If used in large quantities, they are likely to cause environmental pollution. Next, such water balloons require applying pressure to inject water into the balloons, and it is necessary to do this in an environment with a faucet. Many people like to play in places with water such as suburban lawns, along the sea, or along rivers. However, it is difficult to directly inject water to inflate the balloons under normal atmospheric pressure. Due to the lack of water pressure in the water sources in the natural environment, it is difficult to inflate the water balloons on-site, and the playing environment is restricted.

Summary of the Invention

Problems to be Solved by the Invention

[0004] According to various embodiments of the present application, there is provided a toy water balloon that is reusable and can be used in various scenarios.

Means for Solving the Problems

[0005] A toy balloon, comprising a pair of petal-like bodies and a connecting portion connecting the petal-like bodies, each of the petal-like bodies comprising a main body portion and an annular edge portion extending inward from the periphery of the main body portion, a magnet member being attached to each of the annular edge portions, when the petal-like bodies are in a closed state, the petal-like bodies jointly define a cavity for storing water, and the magnet members on the petal-like bodies attract each other to tightly fit the annular edge portions of the petal-like bodies, forming a water-blocking layer to seal the cavity for storing water, and the annular edge portions extend into the cavity for storing water.

[0006] In some embodiments, each of the annular edge portions is an elastic body, and when the petal-like bodies are in a closed state, the annular edge portions of the petal-like bodies deform and tightly fit toward each other under the action of the magnetic attraction force generated by the magnet members.

[0007] In some embodiments, during the process of switching to a closed state under the action of the magnetic attraction force, the two annular edge portions interfere and deform in the thickness direction.

[0008] In some embodiments, each of the annular edge portions is provided with a mating surface for mating with the other annular edge portion, the mating surface of at least one of the annular edge portions is concave or convex in a natural state, and the concave or convex surface deforms toward the other annular edge portion under the action of the magnetic attraction force generated by the magnet member.

[0009] In some embodiments, the mating surface of each of the annular edge portions is concave in a natural state, or the mating surface of one of the annular edge portions is concave in a natural state, the mating surface of the other annular edge portion is flat in a natural state, or the mating surface of one of the annular edge portions is convex in a natural state, the mating surface of the other annular edge portion is concave in a natural state, or the mating surface of one of the annular edge portions is convex in a natural state, the mating surface of the other annular edge portion is flat in a natural state.

[0010] In some embodiments, at least one of the annular edges includes an annular body connected to the corresponding main body portion and a flange extending obliquely inward from the inner side in the circumferential direction of the annular body. The flange is located on the inner side in the lateral direction of the corresponding magnet member. The mating surface of the annular edge is formed by the surface of the annular body and the surface of the flange. The flange abuts against the other annular edge and deforms under the action of the magnetic adsorption force generated by the magnet member.

[0011] In some embodiments, a flange extending obliquely inward is provided on the inner side in the circumferential direction of one of the annular edges, and a notch corresponding to the flange is provided on the inner side in the circumferential direction of the other annular edge. When the petal-like body is in the closed state, the flange extends into the notch and tightly fits against the inner wall of the notch under the action of the magnetic adsorption force generated by the magnet member.

[0012] In some embodiments, the flange is provided with a mating surface for mating with the inner wall of the notch, and the inclination angle of the mating surface of the flange with respect to the central axis of the corresponding annular edge is smaller than the inclination angle of the inner wall of the notch with respect to the central axis of the corresponding annular edge.

[0013] In some embodiments, each of the annular edges includes a mating surface for mating with the other annular edge. An annular protrusion is provided on the mating surface of one of the annular edges, and the mating surface of the other annular edge is a plane in the natural state. When the petal-like body is in the closed state, the annular protrusion compresses the mating surface of the other annular edge under the action of the magnetic adsorption force generated by the magnet member, forming an annular groove on the mating surface of the other annular edge, and the inner walls of the annular protrusion and the annular groove tightly fit against each other.

[0014] In some embodiments, each of the annular edges includes a first layer and a second layer. The first layer extends integrally from the periphery of the main body portion, the second layer is laminated on the first layer, and the magnet member is provided on the second layer.

[0015] In some embodiments, the thickness of the second layer is greater than the thickness of the first layer.

[0016] In some embodiments, the softness of the second layer is greater than the softness of the main body portion. For example, the softness of the second layer is in the range of 50 to 60 degrees, and the softness of the main body portion is in the range of 30 to 40 degrees. The lower the softness, the softer the material.

[0017] In some embodiments, the connecting portion is integrally formed with the second layer of the two annular edges, and the thickness of the connecting portion is smaller than the thickness of the second layer.

[0018] In some embodiments, the thickness of the annular edge of each of the petal-like bodies is greater than the thickness of the main body portion.

[0019] In some embodiments, the main body portions of the pair of petal-like bodies are symmetric with respect to the center line of the connecting portion.

[0020] In some embodiments, the connecting portion can change between an extended state and a bent state in order to correspond to the unfolded state and the closed state of the petal-like body. When the petal-like body is in the closed state, the connecting portion is bent into a C shape or a U shape and protrudes from the outer surface of the petal-like body.

[0021] In some embodiments, each of the annular edges is provided with a mating surface for mating with the other annular edge. The magnet member includes a plurality of magnets arranged at intervals, and the magnetic flux density of the mating surface corresponding to the center position of the magnet is 130 MT to 260 MT.

[0022] In some embodiments, a plurality of receiving grooves for respectively accommodating the magnets are provided on each of the annular edge portions, an adhesive layer is provided between the magnets and the groove walls of the receiving grooves, and each of the annular edge portions is integrally formed around the magnets by injection molding or hot press molding, wrapping the magnets therein. By installing in this way, the connection between the magnets and the annular edge portions becomes stronger. Even if there is a partial looseness between the magnets and the annular edge portions, due to the existence of the adhesive layer, it is difficult for the magnets to fall off from the edges of the water balloons, and the safety in use is improved.

Advantages of the Invention

[0023] For the water balloon toy of the present invention, by attaching a magnet member to the annular edge portion, the petal-like bodies can be closed through the magnetic cooperation of the magnet member. When the closed water balloon toy is impacted and deformed, the water pressure inside the water balloon toy changes, and the magnet member is disengaged from the magnetic cooperation, separating the petal-like bodies. By providing the magnet member, the water balloon toy can be repeatedly opened and closed, so it is reusable, clean and environmentally friendly. When the water balloon toy is filled with water in two petal-like bodies and then closed using the magnet member, the water injection is completed, and water injection can be performed without requiring a water source with a specific pressure. It can be used in various scenarios and has high applicability.

Mode for Carrying Out the Invention

[0026] To facilitate the understanding of the present invention, the present invention will be described in more detail below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention can be understood more completely and thoroughly.

[0027] Unless otherwise defined, all technical terms and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention pertains. The terms used in the specification of the present invention are for the purpose of describing specific embodiments only and are not intended to limit the present invention.

Examples

[0028] Referring to FIGS. 1 to 6, it is a water balloon of a toy according to Embodiment 1 of the present invention that is thrown as a tool and used during game play and entertainment. The water balloon of the toy has a closed state and a deployed state. After the water balloon of the toy is put into water and filled with water, and then returned to the closed state, the water balloon of the toy forms a cavity for storing sealed water. During the game process, when the water balloon of the toy hits a human body, the ground, or a hard object, the water balloon of the toy is compressed and broken into a deployed state, and the stored water scatters to achieve the purpose of the game.

[0029] Specifically, referring to FIGS. 1 to 6, the balloon 10 of the toy according to Embodiment 1 of the present invention includes a pair of petal-like bodies 12 and a connecting portion 14 that connects the petal-like bodies 12. Each petal-like body 12 includes a main body portion (also called a bladder or a water storage utensil) 16 and an annular edge portion 18 that extends laterally inward from the peripheral edge of the main body portion 16 (that is, in a direction away from the peripheral edge of the main body portion 16). That is, the annular edge portion 18 extends inward from the outer edge in the circumferential direction of the main body portion 16 (the direction indicated by the arrow C in FIG. 2) and extends beyond the inner surface of the main body portion 16. A magnet member 20 is attached to each of the annular edge portions 18. The connecting portion 14 can be bent between an extended state and a bent state so that the petal-like bodies 12 can be switched between a closed state and a deployed state. When the two petal-like bodies 12 are in the closed state, the two petal-like bodies 12 jointly define a cavity 22 for storing water. By attracting each other with the magnet members 20 on the two petal-like bodies 12, the annular edge portions 18 of the two petal-like bodies 12 are tightly joined by deformation to form a water shielding layer, and the water shielding layer seals the cavity 22 for storing water. The annular edge portion 18 extends laterally in the cavity 22 for storing water, and the water on both sides in the thickness direction of the annular edge portion 18 in the cavity 22 for storing water applies pressures F1 and F2 to the annular edge portion 18 from two opposite directions, further tightly joining the annular edge portions 18 of the two petal-like bodies 12 and improving the sealing and waterproof effects. When in use, first, the two petal-like bodies 12 are deployed and placed in water and filled with water. Next, the two petal-like bodies 12 are closed and tightly joined by using the magnetic cooperation of the magnet members 20 on the annular edge portions 18 to prevent the water in the cavity 22 for storing water from being lifted and flowing out. When the closed toy balloon 10 hits the human body, the toy balloon 10 deforms, and due to the action of the internal water pressure, the magnet members 20 on the two petal-like bodies 12 are disengaged from the magnetic cooperation, separating the two petal-like bodies 12, and the water in the toy balloon 10 scatters to produce a game effect. Due to the magnetic cooperation of the magnet members 20, the toy balloon 10 can be repeatedly switched between the closed state and the deployed state, so the toy balloon 10 can be reused, is clean and environmentally friendly, and the toy balloon 10 can be filled with water without requiring a water source with a specific pressure and can be used in various scenarios, having high applicability.

[0030] The specific shape of the toy balloon 10 is not limited to a spherical shape, an ellipsoidal spherical shape, an irregular spherical shape, a character shape, etc., as long as it can store water in a closed state. In this embodiment, both of the two petal-shaped bodies 12 are hemispherical spherical shells, the main body portions 16 of the two petal-shaped bodies 12 are symmetric with respect to the center line of the connecting portion 14, the annular edge portions 18 of the two petal-shaped bodies 12 extend radially inward, the outer diameters of the annular edge portions 18 of the two petal-shaped bodies 12 are substantially equal, and when the two petal-shaped bodies 12 are closed, a spherical toy balloon 10 is formed.

[0031] As shown in FIGS. 5 and 6, in Embodiment 1, each annular edge portion 18 is an elastomer that can be elastically deformed. When the petal-shaped body 12 is in a closed state, the annular edge portion 18 of the petal-shaped body 12 is deformed and tightly joined by the action of the magnetic adsorption force generated by the magnet member 20. The annular edge portion 18 is deformable. In the process of the two petal-shaped bodies 12 approaching each other under the action of the magnet member 20, deformation occurs in the annular edge portion 18, and after the annular edge portion 18 is deformed, an elastic restoring force is generated to tightly join the two annular edge portions 18, thereby achieving a good sealing effect.

[0032] Specifically, when the petal-shaped body 12 is switched to a closed state by the action of the magnetic adsorption force generated by the magnet member 20, the two annular edge portions 18 interfere with each other in the thickness direction and are deformed in the thickness direction to tightly join the two annular edge portions 18.

[0033] The specific material of the annular edge portion 18 is not particularly limited as long as it has elasticity and is deformable, such as silicone.

[0034] The material of the main body portion 16 may be the same as or different from that of the annular edge portion 18. For example, the main body portion 16 can be made of a thin and soft sheet such as silicone. When both the main body portion 16 and the annular edge portion 18 are made of silicone, the main body portion 16 can be integrally formed with the whole or a part of the annular edge portion 18.

[0035] The thickness h1 of the annular edge 18 of each petal-shaped body 12 is greater than the thickness h2 of the main body 16, and the thickness h2 of the main body 16 is preferably in the range of 0.2 to 1 mm, such as 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc. The thickness of the main body 16 is relatively thin, which can reduce the pain when the toy balloon 10 hits the human body. By providing a relatively thick annular edge 18 on the thin main body 16, it is convenient for attaching the magnet member 20.

[0036] In some embodiments, the main body 16 has a uniform thickness, but in other embodiments, it can be understood that the main body 16 can also have a non-uniform thickness, that is, the thickness of some parts can be thick and the thickness of some parts can be thin. In this case, the thickness h2 of the main body means the thickness at the minimum thickness.

[0037] The thickness h1 of the annular edge 18 is preferably in the range of 2.5 to 5 mm, such as 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, or 5 mm, etc.

[0038] In this embodiment, the magnet member uses a plurality of magnets arranged at intervals. The length of the magnet (along the circumferential direction / longitudinal direction of the petal-shaped body) is preferably in the range of 5 to 15 mm, such as 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, etc. The width (along the radial direction / transverse direction of the petal-shaped body) is preferably in the range of 1 to 3 mm, such as 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm, etc. The height (along the thickness direction of the edge) is preferably in the range of 1 to 3 mm, such as 1 mm, 1.5 mm, 2 mm, 2.5 mm, or 3 mm, etc. In this embodiment, the magnet is a permanent magnet. If the magnetic flux density of the magnet is too low and the attraction force between the magnets is too small, the water balloon will open before reaching the target and water will easily leak in the air. When the number of magnets increases, the distance between the magnets will inevitably become narrower (the size of the children's toy water balloon must not be too large, because if it is too large, children will not be able to hold it with their hands, so the size of the entire water balloon is limited), which affects the deformation of the joint surface and also affects the sealing effect of the water balloon. If the magnetic flux density is too high, the attraction force between the magnets is too large, making it difficult for the water balloon to open. If it hits a child during play, the pain will increase further and the child is more likely to get injured. It is necessary to consider both the deformation ability of the edge and the magnetic adsorption force (not too large and not too small) between the two joint surfaces. As a result of extensive research by the inventor of the present application, a preferred magnetic flux density range has been found, that is, the magnetic flux density of the joint surface corresponding to the center position of the magnet is preferably 130 MT to 260 MT (millitesla), in which case the requirements of the deformation ability and the magnetic adsorption force can be fully considered.

[0039] Each of the annular edges 18 is provided with a joint surface 24 for joining with the other annular edge 18. In the state where the toy water balloon 10 is closed, the joint surfaces 24 of the two annular edges 18 are joined to each other. The joint surface 24 of at least one annular edge 18 is concave or convex in the natural state. Due to the action of the magnetic adsorption force generated by the magnet member 20, the concave surface or the convex surface deforms toward the other annular edge 18, and the two joint surfaces 24 are tightly joined by the action of the magnet member 20 to achieve a sealing effect and prevent water leakage.

[0040] Specifically, at least the mating surface 24 of one of the annular edges 18 is concave in the natural state. When the magnet members 20 on the two petal-like bodies 12 attract each other, the concave surface deforms toward the other annular edge 18 under the action of the magnetic attraction force. The natural state refers to a state where no external force acts on the two annular edges 18, for example, a state where the two magnet members 20 do not cooperate magnetically. When the magnet members 20 on the two petal-like bodies 12 attract each other, the magnetic attraction force generated by the magnet members 20 brings the two annular edges 18 closer to each other, the concave surface deforms, and finally the two mating surfaces are tightly joined to achieve a sealing effect, and it is also possible to prevent water leakage between the two annular edges 18 due to the inability to be tightly joined due to processing or assembly errors. Since the requirements for accuracy are reduced, the manufacturing difficulty is lowered.

[0041] Specifically, in this embodiment, the mating surface 24 of one of the annular edges 18 is concave in the natural state, and the mating surface 24 of the other annular edge 18 is flat in the natural state. The concave surface deforms toward the flat surface of the other annular edge 18 under the action of the magnetic attraction force generated by the magnet member 20 and tightly joins with the flat surface. When the petal-like body 12 is in the closed state, the annular edge 18 having the concave surface deforms under the action of the magnetic attraction force, and the concave surface deforms into a flat surface so as to tightly join with the flat surface of the other annular edge 18. Since the flat surface has a relatively lower manufacturing difficulty compared to the concave surface, making one mating surface 24 concave and the other mating surface 24 flat can reduce the manufacturing difficulty while improving the sealing effect.

[0042] The specific method for forming the concave surface is not particularly limited. For example, the central part of the mating surface 24 of the annular edge 18 or the entire mating surface 24 may be recessed to form an arc surface, or it may be defined by a plurality of non-coplanar planes or curved surfaces.

[0043] In this embodiment, at least one of the annular edge portions 18 includes an annular main body 26 connected to the corresponding main body portion 16 and a flange 28 extending obliquely inward from the inner side in the circumferential direction of the annular main body 26. The flange 28 is located laterally inward of the corresponding magnet member 20 and is deformable. That is, on the lateral direction R of the main body portion 12, the flange 28 is located inside the magnet member 20. The outer surface of the annular main body 26 and the outer surface of the flange 28 form a mating surface, i.e., a concave surface, of the annular edge portion 18. The flange 28 abuts against the other annular edge portion 18 due to the action of the magnetic attraction force generated by the magnet member 20, that is, interference occurs and deformation occurs. Specifically, in this embodiment, one of the annular edge portions 18 includes the annular main body 26 and the flange 28. The annular main body 26 and the flange 28 are arranged at an included angle. The included angle between the annular main body 26 and the flange 28 is greater than 90° and less than 180°. That is, the included angle between the straight portion and the inclined portion of the concave surface is greater than 90° and less than 180°. The mating surface 24 of the other annular edge portion 18 is a plane in the natural state. When the two petal-shaped bodies 12 approach each other due to the action of the magnet member 20, the flange 28 of the annular edge portion 18 abuts against the other annular edge portion 18 and deforms due to the action of the magnetic attraction force generated by the magnet member 20. The flange 28 changes from an inclined state to a straight state. Finally, the surface of the flange 28 is positioned on the same plane as the surface of the annular main body 26 to form a complete plane and tightly fit with the mating surface 24 of the other annular edge portion 18. At this time, the flange 28 abuts against the other annular edge portion 18 by its own elastic force, and the sealing effect is enhanced. The thickness of the flange 28 gradually decreases in the direction away from the main body portion. The thickness of the flange 28 is smaller than the thickness of the annular main body 26. The thickness of the flange 28 is preferably in the range of 0.3 to 0.43 mm, and the thickness of the annular main body 26 is the thickness of the annular edge portion 18.

[0044] As shown in FIGS. 7 and 8, in other embodiments, the mating surface 24 of the two annular edges 18 is concave in the natural state, that is, each of the annular edges 18 includes an annular body 26 and a flange 28. When the two petal-like bodies 12 approach each other under the action of the magnet member 20, the two flanges 28 come into contact, deform under the action of the magnet member 20, the two flanges 28 change from an inclined state to a straight state, and finally the surface of the flange 28 is positioned on the same plane as the surface of the corresponding annular body 26 to form a complete plane and be tightly joined.

[0045] As shown in FIG. 5, in Example 1, the annular edge 18 includes a first layer 30 and a second layer 32. The first layer 30 extends integrally from the periphery of the main body portion 16, that is, the first layer 30 is integrally formed with the main body portion 16 and extends laterally inward from the periphery of the main body portion 16. The second layer 32 is laminated on the side opposite to the main body portion 16 of the first layer 30. A receiving groove is provided in the second layer 32, the magnet member 20 is provided in the receiving groove of the second layer 32, the mating surface 24 is located on the side opposite to the first layer 30 of the second layer 32, and the second layer 32 of one annular edge 18 includes an annular body 26 and a flange 28. During assembly, the magnet member 20 such as a magnet is first fixed in the mounting groove / hole of the second layer 32 (for example, the magnet can be directly fixed therein when forming the second layer 32 by an injection molding method), and then the main body portion 16 and the first layer 30 are integrally formed on the second layer and the magnet by an injection molding method. The first layer 30 is laminated on the second layer 32 to cover the mounting groove / hole of the magnet. In some embodiments, an adhesive layer is provided between the magnet and the groove wall of the receiving groove, and the annular edge is integrally formed around the magnet by an injection molding or a hot press molding method to wrap the magnet therein. For example, before injection molding or hot press molding, first apply an adhesive to the magnet, and then integrally form the annular edge directly around the magnet, so that an adhesive layer is formed between the magnet and the groove wall of the receiving groove of the annular edge. By installing in this way, the connection between the magnet and the annular edge becomes stronger. Even if the magnet and the annular edge are partially loosened during use, due to the presence of the adhesive layer, it is difficult for the magnet to fall off from the edge of the water balloon, and the safety in use is improved.

[0046] The specific fixing method between the first layer 30 and the second layer 32 is not particularly limited. For example, after the first layer 30 and the second layer 32 are each formed, an adhesive can be applied between the first layer 30 and the second layer 32 to bond and fix the first layer 30 and the second layer 32.

[0047] Preferably, the thickness of the second layer 32 is greater than the thickness of the first layer 30, and the magnet member 20 is attached to the second layer 32. The thickness of the second layer 32 is relatively thick, which can facilitate the attachment of the magnet member 20. The thickness of the second layer 32 is preferably in the range of 1.5 to 2.2 mm, such as 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, and the thickness of the first layer 30 is preferably in the range of 1.3 to 1.7, such as 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm.

[0048] Preferably, the softness of the second layer 32 is greater than the softness of the first layer 30 and the main body 16. With such a design, the main body 16 becomes softer, and the pain when the balloon toy 10 hits the human body is reduced. The second layer 32 becomes harder, making it easier to fix the magnet member 20 therein. The softness of the second layer 32 is preferably in the range of 50 degrees to 60 degrees (belonging to medium softness), more preferably in the range of 54 degrees to 56 degrees, such as 55 degrees. The softness of the main body 16 is preferably in the range of 30 degrees to 40 degrees, more preferably in the range of 34 degrees to 36 degrees, such as 35 degrees. The lower the softness, the softer the material.

[0049] As shown in FIG. 3, the specific type of the magnet member 20 is not particularly limited. For example, it can be a magnet attached to the annular edge portion 18, or before forming the annular edge portion 18, magnetic powder can be put into the raw material of the annular edge portion 18, and after forming the annular edge portion 18, the magnetic powder can be embedded in the annular edge portion 18. In this embodiment, the magnet member 20 is a magnet, a receiving groove is provided on the annular edge portion 18, and the magnet is received in the receiving groove. Specifically, the receiving groove is provided on the side of the first layer 30 close to the second layer 32, and by fixing the second layer 32 and the first layer 30, the magnet is prevented from falling off the annular edge portion 18.

[0050] The specific number of the magnet members 20 on each annular edge portion 18 is not particularly limited, and it may be one or a plurality. In this embodiment, a plurality of magnet members 20 are provided on each annular edge portion 18, the number of the magnet members 20 on the two annular edge portions 18 is the same, and they correspond one-to-one. The plurality of magnet members 20 on the corresponding annular edge portion 18 are arranged at equal intervals along the circumferential direction of the annular edge portion 18.

[0051] As shown in FIGS. 1 and 2, in the first embodiment, the connecting portion 14 is made of an elastic material and can be bent between an extended state and a bent state. That is, the connecting portion 14 can be deformed to form different bending arcs, so that the petal body 12 can be switched between an unfolded state and a closed state. By using the connecting portion 14 to connect the two petal bodies 12, even if the two petal bodies 12 are separated when the toy balloon 10 hits the human body, the two petal bodies 12 remain connected by the connecting portion 14, preventing the loss of the petal bodies 12, which is convenient for the user to use.

[0052] Both ends of the connecting part 14 can be connected to two main body parts 16 respectively, and may be connected to two annular edge parts 18 respectively, or one end of the connecting part 14 may be connected to the main body part 16 of one petal body 12, and the other end may be connected to the annular edge part 18 of the other petal body 12. In this embodiment, both ends of the connecting part 14 are fixed to two annular edge parts 18 respectively. Specifically, the connecting part 14 is integrally formed with the second layer 32 of the two annular edge parts 18, and the thickness of the connecting part 14 is smaller than the thickness of the second layer 32. The thickness of the connecting part 14 is preferably in the range of 0.2 - 1 mm, such as 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, etc.

[0053] When the pair of petal bodies 12 are in the closed state, the connecting part 14 is bent into a C - shape or a U - shape and protrudes from the outer surface of the petal body 12. In this embodiment, the connecting part 14 is a flexible member, and when the toy balloon 10 is in the closed state, the connecting part 14 is bent into a C - shape or a U - shape.

Embodiment

[0054] Referring to FIGS. 9 - 13, on the inner side in the circumferential direction of one annular edge part 18a of the toy balloon 10a according to Embodiment 2 of the present invention, a flange 28a extending obliquely inward is provided, and a notch 36 is provided on the inner side in the circumferential direction of the other annular edge part 18a corresponding to the flange 28a. When the petal body 12a is in the closed state, the flange 28a extends into the notch 36 and tightly fits with the inner wall of the notch 36 under the action of the magnetic adsorption force generated by the magnet member 20a, thereby achieving a sealing effect.

[0055] In this embodiment, since the flange 28a is made of an elastic material, it can be deformed. The flange 28a has a mating surface for mating with the inner wall of the notch 36, and the inclination angle of the mating surface of the flange 28a with respect to the central axis Z of the corresponding annular edge 18a is smaller than the inclination angle of the inner wall of the notch 36 with respect to the central axis Z of the corresponding annular edge 18a. That is, the angle formed by the mating surface of the flange 28a and the central axis Z of the annular edge 18a is smaller than the angle formed by the inner wall of the notch 36 and the central axis Z of the annular edge 18a. Since the inclination degree of the flange 28a is smaller than that of the notch 36, during the process of inserting the flange 28 into the notch 36, the inner wall of the notch 36 compresses the flange 28a to deform the flange 28a, and finally the mating surface of the flange 28a and the inner wall of the notch 36 are tightly combined. The flange 28a abuts against the other annular edge 18a by its own elastic force, is tightly combined with the inner wall of the notch 36, improves the sealing effect between the two petal-like bodies 12a, and prevents the problem of water leakage caused by the flange 28a being unable to be tightly combined with the inner wall of the notch 36 due to processing or assembly errors, reduces the requirement for accuracy, and reduces the manufacturing difficulty.

Embodiment

[0056] As shown in FIGS. 14 to 18, one of the mating surfaces of the two annular edges 18b of the water balloon 10b of the toy according to Embodiment 3 of the present invention is a convex surface, and the other is a flat surface in the natural state. The flat surface is compressed by the magnetic adsorption force generated by the magnet member 20b to be deformed into a concave shape and tightly combined with the convex surface.

[0057] Specifically, an annular protrusion 38 is provided on the mating surface of one annular edge 18b. The convex surface is located on the annular protrusion 38. The mating surface of the other annular edge 18b is a flat surface in the natural state. When the petal-like body 12b is in the closed state, the annular protrusion 38 compresses the mating surface of the other annular edge 18b by the action of the magnetic adsorption force generated by the magnet member 20b, forms an annular groove 40 on the mating surface of the other annular edge 18b, and at the same time, the annular protrusion 38 is also deformed by the action of the other annular edge 18b, so that the outer surface of the annular protrusion 38 is tightly combined with the inner wall of the annular groove 40. At this time, the annular protrusion 38 exerts a sealing effect and achieves the effect of preventing water leakage.

[0058] In another embodiment, one of the mating surfaces of the two annular edges may be convex and the other may be concave, and when the petals are in a closed state, the convex surface is deformed and fitted tightly with the concave surface due to the magnetic attraction force generated by the magnet member.

[0059] In the above embodiment, each petal is hemispherical in shape and the toy water balloon is spherical in its closed state.

[0060] It will be appreciated that in some embodiments, the toy water balloon may assume other irregular (non-spherical) configurations in the closed state. EXAMPLES

[0061] 19 and 20, the toy water balloon 10c according to the fourth embodiment of the present invention has a character shape, specifically, when the two petals 12c are closed, the toy water balloon 10c has a duck shape, which makes the toy water balloon 10c look cuter. In this embodiment, the two petals 12c are symmetrical with respect to the midline of the connecting portion 14c, and each petal 12c itself has an asymmetric structure, and the annular edge of each petal 12c has a non-circular shape. EXAMPLES

[0062] 21 and 22, the toy water balloon 10d according to the fifth embodiment of the present invention has a character shape, specifically, when the two petals 12d are closed, the toy water balloon 10d has a crab shape, which makes the toy water balloon 10d look cuter. In this embodiment, the two petals 12d are symmetrical with respect to the midline of the connecting portion 14d, and each petal 12d itself has an asymmetric structure, and the annular edge of each petal 12d has a non-circular shape.

[0063] The water balloon 10 of the present invention is not limited to storing water, and it should be understood that it can also store other liquids suitable for people's entertainment and play, such as beer, milk, or other liquids that are harmless to the human body or potable.
