Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap manufacturing, in particular to an instant bottle cap and an instant bottle. Background Art

[0002] Traditional packaged beverages (such as bottled tea drinks) are sold after the solute is mixed with water. In order to extend the shelf life of the beverage, various artificial chemicals such as preservatives and stabilizers are added, which not only affects the taste, but also causes a certain degree of harm to the human body. This is not advocated by the current concept of healthy living. Therefore, ready-to-use bottle caps came into being. The solute is sealed and stored in the bottle cap, which can effectively and stably preserve the activity of various nutrients. When the beverage is needed, the solute in the bottle cap is released into the water, which not only obtains a longer shelf life, but also tastes fresh. It does not require the addition of any artificial preservatives and is more in line with the needs of healthy drinks. Ready-to-use bottle caps with the above functions usually adopt a sealing film or a weak layer structure design. When drinking, the sealing film is broken or the weak layer is opened, so that the solute in the storage cavity flows out and mixes with the water in the bottle.

[0003] In the existing instant bottle cap, the side wall of the upper cover is connected to the pressing part by an elastic part. When pressing, the elastic force of the elastic part needs to be overcome. In order to prevent accidental touch and pressing the pressing part, the height of the connecting part is generally set to be greater than the pressing part. Only fingers can be used for pressing. The contact area with the pressing part is small, it is difficult to apply pressing force, and the user experience is not good. Utility Model Content

[0051] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0052] Example 1

[0053] Reference Figures 1-6 As shown, the embodiment of the present invention proposes an upper cover 1, a lower cover 2 and a sealing plug 3, wherein the upper cover 1, the lower cover 2 and the sealing plug 3 together form a sealed storage cavity 5, wherein:

[0054] The upper cover 1 includes an integrally formed pressing portion 11, an elastic portion 12, a connecting portion 13, an upper cover tube 15 and a top column 14, the edge of the pressing portion 11 extends outwardly in the direction close to the storage cavity 5 to form the elastic portion 12; the edge of the elastic portion 12 extends radially outwardly along the upper cover tube 15 to form the connecting portion 13, the height of the pressing portion 11 is greater than the height of the connecting portion 13 to which it belongs, that is, the distance from the pressing portion 11 to the lower cover 2 is greater than the distance from the connecting portion 13 to the lower cover 2; the top column 14 is arranged below the pressing portion 11, and the lower end of the top column 14 is clamped with the sealing plug 3; the inner side of the edge of the connecting portion 13 extends toward the storage cavity 5 to form the upper cover tube 15;

[0055] The lower cover 2 includes a lower cover tube 21 and a lower cover body 22. The lower cover tube 21 is integrally sleeved on the lower cover body 22. The bottom of the lower cover tube 21 is sealed and clamped with the sealing plug 3. The inner wall of the lower cover body 22 is connected to the outer wall of the upper cover tube 15. The top surface of the lower cover body 22 is pressed and connected to the bottom surface of the connecting portion 13. The connection is sealed by ultrasonic welding.

[0056] The protective cover 4 is detachably connected to the lower cover body 22 and forms a receiving cavity 6 with the lower cover 2 and the upper cover 1. The receiving cavity 6 is used to accommodate the pressing portion 11 and the elastic portion 12. The top surface of the protective cover 4 can be provided with a processing chamfer to facilitate processing and improve appearance.

[0057] The pressing portion 11 can drive the elastic portion 12 to deform and move downward under the action of external force, and the top column 14 simultaneously pushes the sealing plug 3 to move downward, so that the sealing plug 3 is disconnected from the bottom of the lower cover tube 21 to open the storage chamber 5.

[0058] In this embodiment, the inner wall of the lower cover body 22 and the outer wall of the upper cover tube 15 can be connected by interference fit, and the upper cover tube 15 is inserted into the lower cover body 22 until the top surface of the lower cover body 22 is pressed and connected with the bottom surface of the connecting portion 13, and then the connection is ultrasonically welded so that the welding position is located at the upper part of the bottle cap as a whole, which is conducive to the implementation of ultrasonic near-field welding, thereby improving production efficiency.

[0059] The instant bottle cap proposed in this embodiment forms an accommodating cavity 6 with the protective cover 4, the lower cover 2 and the upper cover 1. The accommodating cavity 6 accommodates the pressing portion 11 and the elastic portion 12 to prevent accidental touching of the pressing portion 11. The height of the pressing portion 11 can be set to be greater than the height of the connecting portion 13 to which it belongs, that is, the pressing portion 11 is designed to protrude upward. When applying downward force to the pressing portion 11, it can be pressed downward by the palm of the hand, and the contact area with the pressing portion 11 is large, so the pressing force can be better applied, thereby improving the user experience and reliability.

[0060] In some embodiments, the outer wall of the lower cover 22 is provided with an abutment portion 221, and the protective cover 4 abuts against the abutment portion 221. A gap is provided between the inner end of the protective cover 4 away from the abutment portion 221 and the pressing portion 11. After the protective cover 4 is connected to the lower cover 22, it protects the pressing portion 11, preventing damage to the packaging caused by accidental contact with the pressing portion 11, and improving the reliability of the device.

[0061] In some embodiments, the accommodating chamber 6 and the storage chamber 5 are not connected. When force is applied to the protective cover 4, no pressure is generated on the storage chamber 5 to open it, which can improve the reliability of the device. After the protective cover 4 is removed, the storage chamber 5 remains sealed, and the removal of the protective cover 4 does not affect the sealing of the storage chamber 5.

[0062] In some embodiments, the upper cover tube 15 includes an inner cover wall 151 and an outer cover wall 152, a positioning groove 153 is formed between the inner cover wall 151 and the outer cover wall 152, and a positioning protrusion 222 is provided on the top of the lower cover body 22, and the positioning protrusion 222 is snap-fitted into the positioning groove 153. By forming the positioning groove 153 between the inner cover wall 151 and the outer cover wall 152, and providing the positioning protrusion 222 on the top of the lower cover body 22, and snap-fitting into the positioning groove 153, the upper cover tube 15 and the lower cover body 22 are positioned, facilitating ultrasonic welding between the upper cover tube 15 and the lower cover body 22, thereby improving welding quality.

[0063] In some embodiments, as Figure 5 As shown, a fuse 131 is provided at the portion where the bottom surface of the connecting portion 13 abuts the positioning protrusion 222. The longitudinal section of the fuse 131 is a triangle. The fuse 131 is used for welding during ultrasonic welding to achieve a better welding effect. During ultrasonic welding, the smaller the contact area between the two plastic workpieces, the more concentrated the ultrasonic energy is, while reducing the overall energy required for melting and fusing the plastics. The fuse 131 is designed in this way, with a raised triangle provided on the welding interface of a plastic part. The basic function of the fuse 131 is to concentrate the vibration energy at the tip of the triangle, and the accumulated heat thereafter forms a uniform plastic melt flow across the entire welding interface. The fuse 131 has many advantages. It can increase the strength of the weld, reduce cold welds, flash and amplitude, improve the perfection of the welded workpiece, and even reduce processing time.

[0064] In some embodiments, the positioning protrusion 222 extends upward along the inner side of the lower cover body 22, so that after the positioning protrusion 222 is engaged with the positioning groove 153, the outer wall of the outer cover wall 152 is flush with the outer wall of the lower cover body 22, thereby preventing obstruction when the protective cover 4 is mounted on the lower cover body 22, thereby improving the reliability and stability of the device. Of course, the outer wall of the outer cover wall 152 can also be located inside the outer wall of the lower cover body 22.

[0065] In some embodiments, the height of the outer cover wall 152 is less than that of the inner cover wall 151, and a guiding slope 1511 is provided at the bottom of the outer wall of the inner cover wall 151. Because the height of the outer cover wall 152 is less than that of the inner cover wall 151, the inner cover wall 151 first contacts the lower cover body 22, thereby enabling preliminary positioning of the upper cover tube 15. The guiding slope 1511 is provided at the bottom of the outer wall of the inner cover wall 151 to guide the inner cover wall 151 when it contacts the lower cover body 22, facilitating engagement between the positioning groove 153 and the positioning protrusion 222, thereby improving assembly convenience.

[0066] In some embodiments, the elastic portion 12 includes an arc-shaped first elastic portion 121 and a second elastic portion 122. The first elastic portion 121 is connected to the pressing portion 11 and the second elastic portion 122 respectively. The connection between the first elastic portion 121 and the second elastic portion 122 is smoothly transitioned. The center of the first elastic portion 121 is close to the material storage cavity 5, the center of the second elastic portion 122 is away from the material storage cavity 5, and the second elastic portion 122 is connected to the connecting portion 13. Because the first elastic portion 121 is connected to the pressing portion 11 and the second elastic portion 122 respectively, the center of the first elastic portion 121 is close to the material storage cavity 5, and the center of the second elastic portion 122 is away from the material storage cavity 5, when the pressing portion 11 is pressed downward, the first elastic portion 121 contracts downward, which has less resistance to the pressing portion 11, making it easier to press the pressing portion 11 with less effort, thereby improving reliability and user experience.

[0067] In some embodiments, a bottle mouth connection groove is formed between the lower cover body 22 and the lower cover cylinder 21; the inner wall of the lower cover body 22 is provided with an internal thread 223 for connecting with the external thread of the bottle mouth. By forming a bottle mouth connection groove between the lower cover body 22 and the lower cover cylinder 21, the inner wall of the lower cover body 22 is provided with an internal thread 223, which is used to connect with the external thread of the bottle mouth, thereby achieving the connection between the bottle cap and the bottle body.

[0068] In some embodiments, the lower cover 2 further includes an anti-theft ring 23 disposed on the bottom of the lower cover body 22. The top of the anti-theft ring 23 is integrally connected to the bottom edge of the lower cover body 22 via a plurality of filament-like structures. Due to the provision of the anti-theft ring 23, when the user unscrews the instant bottle cap, the anti-theft ring 23 breaks off from the lower cover body 22, remaining on the bottle. The user can determine whether the instant bottle cap is sealed intact or has been maliciously opened based on whether the anti-theft ring 23 is broken, thereby ensuring the food safety of the packaged beverage.

[0069] It should be noted that in this embodiment, the lower cover tube 21 is straight-cylindrical, with its inner diameter remaining constant along its axis, and the inner wall of the bottom of the lower cover tube 21 is sealed to the sealing plug 3. The straight-cylindrical design allows for a larger discharge opening after the sealing plug 3 is opened, making it suitable for filling large amounts of solute particles with poor fluidity or viscous liquids such as meal replacement powder, milk tea ingredients, honey, etc.

[0070] In some other embodiments, the lower cover tube may also be funnel-shaped.

[0071] In some embodiments, the sealing plug 3 includes: a plug ring 31, a plug surface 32, a plug bottom 33, and a snap-in hole 34. The sealing plug 3 is a cone-like structure. The portion directly sealed with the bottom end of the inner wall of the lower cover tube 21 is the plug ring 31. The end facing the storage chamber 5 is the plug surface 32, which is a cone with an arc-shaped slope. The top of the cone is provided with a snap-in hole 34. The top column 14 of the upper cover 1 is plugged into the snap-in hole 34. The inner wall of the snap-in hole 34 and the outer wall of the top column 14 are formed with matching annular grooves 1411 and annular protrusions 341 to achieve a more secure and stable plug-in effect, thereby preventing the sealing plug 3 from falling off after the storage chamber 5 is opened. The plug bottom 33 is a lightweight structure with multiple nested circular rings of varying sizes, and the bottoms of the multiple rings are flush. After the sealing plug 3 and the lower cover tube 21 are sealed and snap-in in place, the bottoms of the two are flush.

[0072] In some embodiments, as Figure 6 As shown, a limiting step 211 is provided at the bottom of the inner wall of the lower cover tube 21, and the plug surface 32 abuts against the limiting step 211 so that the plug bottom 33 is flush with the bottom of the lower cover tube 21, so that the sealing film 7 can be covered on the lower surface of the sealing plug 3 flush with the lower cover tube 21 through heat sealing or ultrasonic welding process, so as to completely cover the structural gap between the sealing plug 3 and the bottom of the lower cover tube 21 and achieve a complete sealing effect.

[0073] In one embodiment, the outer wall of the plug ring 31 is provided with an integrally formed annular convex sealing line 311, the diameter of which is slightly larger than the inner diameter of the lower cover tube 21, so as to form an interference fit between the sealing plug 3 and the lower cover tube 21 through the elasticity of the injection molded part to achieve a better sealing effect.

[0074] In one embodiment, the top column 14 of the upper cover 1 further includes a column core 141 and a plurality of supporting wing plates 142 integrally connected to the pressing portion 11 . This lightweight structure allows the top column 14 to have greater strength to better withstand downward force.

[0075] In one embodiment, an annular protrusion 341 is provided on the inner wall of the engaging hole 34, and an annular groove 1411 is provided on the outer wall of the top column 14. The annular groove 1411 engages with the annular protrusion 341. The engagement between the annular groove 1411 and the annular protrusion 341 achieves a more secure and stable insertion effect, thereby preventing the sealing plug 3 from falling off after the storage chamber 5 is opened.

[0076] In one embodiment, the instant bottle cap further includes a sealing film 7, which is a composite material with high barrier properties. In order to further enhance the sealing performance, the sealing plug 3 and the lower surface flush with the lower cover tube 21 can be welded with the sealing film 7 by ultrasonic or hot melt process to cover the gaps between the structural parts, thereby achieving a seamless and thorough sealing effect.

[0077] The working principle of the instant bottle cap of this embodiment is: first, the upper cover 1 and the lower cover 2 are assembled together, the positioning protrusion 222 of the lower cover body 22 is snapped into the positioning groove 153 of the upper cover tube 15, the top surface of the lower cover body 22 is pressed and connected with the bottom surface of the connecting portion 13, and the connection is firmly sealed by ultrasonic welding, and the two form a storage chamber 5 with a bottom opening; then the assembled upper cover 1 and lower cover 2 are inverted so that the opening at the bottom of the lower cover tube 21 faces upward, and an appropriate amount of solute is injected into the storage chamber 5 through this opening, and then the plug surface 32 of the sealing plug 3 is assembled to the bottom of the lower cover body 22 facing the storage chamber 5, so that the top column 14 of the upper cover 1 is inserted into the snapping hole 34 of the sealing plug 3 to form a firm snap connection, and at the same time, the plug ring 31 of the sealing plug 3 is sealed and connected to the inner wall of the bottom of the lower cover tube 21, thereby sealing the solute in the storage chamber 5. In order to further enhance the sealing performance, the lower surface of the sealing plug 3 flush with the lower cover body 22 is covered with a sealing film 7 by ultrasonic welding or hot-melt process to cover the gaps between the structural parts and achieve a seamless and thorough sealing effect. Then, the protective cover 4 is sleeved on the outside of the lower cover body 22 and covers the top of the pressing part 11 to prevent accidental pressing. The instant bottle cap is installed. Furthermore, after the bottle body is purified and filled with water, the instant bottle cap is assembled to the bottle body by an automatic screw-on process. The instant bottle cap is provided with an internal thread 223, and the bottle mouth of the bottle body is provided with an external thread. The instant bottle cap and the bottle body are tightened by the internal thread 223 and the external thread to form a sealed fit. The bottle using the instant bottle cap completes the complete production, processing and assembly.

[0078] When in use, open the protective cover 4, press the pressing part 11 of the upper cover 1 downward with your palm or fingers, push the top column 14 to drive the sealing plug 3 to move downward, so that the sealing plug 3 is separated from the sealing shield of the inner wall of the lower cover body 22, thereby opening the storage chamber 5, and the solute pre-filled in the storage chamber 5 falls out from the gap between the sealing plug 3 and the bottom of the lower cover body 22 under the action of gravity, falls into the bottle body and mixes and dissolves with the water in the bottle body. After shaking and mixing evenly or letting it stand for a period of time to fully dissolve, it can be drunk.

[0081] The top surface of the lower cover body 22 is pressed against the bottom surface of the protective portion 13 and there is no ultrasonic welding at the connection. Instead, the lower cover body 22 is snap-fitted to the upper cover tube 15. Specifically, a snap-fitting groove 1521 is provided on the inner wall of the outer cover wall 152, and a snap-fitting protrusion 2221 is provided on the outer wall of the positioning protrusion 222. The snap-fitting protrusion 2221 snaps into the snap-fitting groove 1521 to achieve a snap-fit connection between the lower cover body 22 and the upper cover tube 15.

[0082] A snap ring protrusion 212 is provided at the bottom of the outer wall of the lower cover tube 21. The snap ring protrusion 212 is snapped into the slot provided on the plug ring 31 to achieve a sealed connection between the lower cover tube 21 and the sealing plug 3.

[0083] The sealing film 7 is not required, and the lower surface of the sealing plug 3 that is flush with the lower cover tube 21 does not have the sealing film 7 .

[0084] The ready-to-use bottle cap of this embodiment is suitable for packaging products with low sealing requirements (such as honey). Considering the packaging of honey, a pure snap-fit structure can meet the sealing requirements, and ultrasonic welding and laminating processes can be omitted to save costs.

[0085] Based on the same concept, the present invention also proposes a ready-to-use bottle, such as Figure 10 As shown, it includes a bottle body 200 and the instant bottle cap 100. The bottle mouth of the bottle body 200 is provided with an external thread, and the inner wall of the lower cover body 22 is provided with an internal thread 223. The internal thread 223 is sealed and connected to the external thread.

[0086] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
