[0065] Please see Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of a container structure with a bottle cap receiving space according to an embodiment of the present invention, and Figure 2 This is a schematic diagram of the bottle cap and light-emitting component of a container structure with a bottle cap receiving space according to an embodiment of the present invention. The container structure 1 with a bottle cap receiving space according to an embodiment of the present invention includes a bottle cap 10, a light-emitting component 20, and a bottle body 30.

[0066] The bottle cap 10 has an internal thread 11. The bottle cap 10 includes a top wall 12, an annular wall 13 connected to the top wall 12, and a bottom 14. The top wall 12 includes an outer top wall 121 and an inner top wall 122 opposite to the outer top wall 121. The annular wall 13 includes an upper annular wall 131 and a lower annular wall 132 adjacent to the upper annular wall 131. The lower annular wall 132 is connected to the bottom 14, and the internal thread 11 is located on the inner side of the lower annular wall 132. Specifically, the upper annular wall 131 refers to the annular wall of the bottle cap 10 from the inner top wall 122 to the topmost thread of the internal thread 11, and the lower annular wall 132 refers to the annular wall 13 of the bottle cap 10 from the topmost thread of the internal thread 11 to the bottom 14 of the bottle cap 10. The bottom 14 of the bottle cap 10 refers to the part that contacts the table when the top wall 12 of the bottle cap 10 is placed on the table in a direction away from the table. Furthermore, the bottle cap 10 also includes a second receiving space 15, which is formed by the inner top wall 122 and the upper ring wall 131 of the bottle cap 10.

[0067] The light-emitting component 20 is disposed within the second accommodating space 15. The light-emitting component 20 includes a switch 21, a battery 22, a circuit board 23, a spring contact 24, at least one light-emitting unit 25, and a filter 26. The switch 21 is disposed on the outer top wall 121 of the bottle cap 10. In some embodiments, the switch 21 includes a push-button switch and a touch switch. Push-button switches include, but are not limited to, transient push-button switches, self-locking push-button switches, metal flexible contact switches, micro propeller switches, and diaphragm switches. Touch switches include self-capacitive touch switches and mutual-capacitive touch switches.

[0068] Battery 22 is adjacent to the inner top wall 122 of bottle cap 10. In some embodiments, battery 22 includes a rechargeable or disposable lithium-ion battery. When battery 22 is a rechargeable lithium-ion battery, battery 22 further includes a charging port 221 disposed on the upper annular wall 131 of bottle cap 10, and the charging port 221 charges the battery 22 after being connected to a charging cable and a power source (not shown). Although in Figure 2 In the diagram, battery 22 is shown as one, but it can also be two or more.

[0069] Circuit board 23 is disposed below battery 22, and circuit board 23 includes driver 231 disposed on circuit board 23 and microprocessor 232 adjacent to driver 231. In embodiments where battery 22 is a rechargeable lithium-ion battery, to avoid overheating, overvoltage, overcurrent and short circuit, driver 231 includes battery detection circuit (not shown), and battery 22 further includes charging status indicator 222. The battery detection circuit automatically detects the voltage of battery 22 and switches to trickle charging or power off state after it is fully charged, and charging status indicator 222 surrounds charging port 221. For example, when charging, charging status indicator 222 displays a first color light (e.g., red light), and when fully charged, charging status indicator 222 switches to a second color light (e.g., green light). This is only an example and the present invention is not limited thereto. The microprocessor 232 includes program code for light emission modes, including on, always on, blinking at different frequencies, random blinking, ring scanning light emission, rectangular scanning light emission, simulated candlelight light emission, gradual light emission (e.g., slowly from off to brightest and / or the opposite), multi-color switching light emission, off, or combinations thereof.

[0070] Spring contact 24 connects battery 22 to circuit board 23. The material of spring contact 24 may include stainless steel, gold-plated steel wire, silver-plated steel wire, or a combination thereof. The spring contact 24's elastic compression reduces contact resistance fluctuations, acting as a vibration buffer to provide long-term conductivity reliability and allows for a gap between battery 22 and circuit board 23 to aid in heat dissipation.

[0071] The light-emitting unit 25 is disposed below the circuit board 23. The light source of the light-emitting unit 25 illuminates in a direction away from the battery 22. In some embodiments, the light-emitting unit 25 includes a light-emitting diode (LED). In some embodiments, the light emitted by the light-emitting unit 25 includes, but is not limited to, white light, red light, orange light, yellow light, green light, blue light, indigo light, violet light, and other colors of light. In some embodiments, a plurality of light-emitting units 25 form a light-emitting unit matrix in a ring or rectangle. In this embodiment, the number of light-emitting units 25 includes 4 to 16, for example, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, and 16.

[0072] The filter 26 is positioned below and in close contact with the light-emitting unit 25. The filter 26 allows for multiple refractions and total internal reflections of the light source, resulting in a smooth light intensity distribution and improved lighting consistency and comfort. Additionally, the filter 26 can enclose the second accommodating space 15, isolating the light-emitting unit 25 from the outside environment to prevent the intrusion of moisture and dust.

[0073] After explaining the components of the light-emitting component 20, the operation of each component of the light-emitting component 20 will be described below using a self-capacitive touch switch as an example. In this embodiment, the switch 21 includes copper foil electrodes (not shown), and the copper foil electrodes are adjacent to each other. When a user's finger or other part touches or approaches the copper foil electrodes in the switch 21 located on the bottle cap 10, the human body charge increases the value of the self-capacitive capacitance, triggering an on command (i.e., the on light-emitting mode) in the microprocessor 232. The power from the battery 22 is transmitted to the driver 231 on the circuit board 23 through the spring contact 24. The driver 231 provides current to the light-emitting unit 25 to drive the light-emitting unit 25 to emit light. When the user touches or approaches the copper foil electrodes again with their finger or other part, an off command (i.e., the off light-emitting mode) is triggered in the microprocessor 232, and the driver 231 stops providing current, so that the light-emitting unit 25 is turned off. It is understood that, as long as the program code is designed in advance, the light-emitting mode of the light-emitting unit 25 can be controlled by different pressing or touch methods. For example, a single touch will keep the light on, a double touch will flash, and a long press for more than 3 seconds will turn it off. This is just an example and is not limited to this.

[0074] The bottle body 30 includes a bottle body 31, a bottle mouth portion 32, and a bottle bottom recess 33. A first accommodating space 311 is formed within the bottle body 31, and the bottle body 31 includes a main body 312, a recessed portion 313, and a bottom surface 314 connecting the main body 312 and the recessed portion 313. The bottom surface 314 refers to the surface that contacts the table when the bottle body 31 is upright on a flat table. The recessed portion 313 is located at the bottom of the bottle body 31 and is recessed towards the main body 312. The bottle mouth portion 32 is disposed at the top of the bottle body 31 and connected to the bottle body 31, and an opening 321 is formed around it. The bottle mouth portion 32 includes a first external thread 322. In some embodiments, the bottle body 30 is integrally formed. In some embodiments, the bottle body 31 includes an optical pattern 315. Optical patterns 315 are disposed on the body 312, and the optical patterns 315 include multiple geometric patterns, such as rhombuses, circles, triangles, rectangles, irregular shapes, embossed patterns, or combinations thereof. In some embodiments, the bottle cap 10 has a first height H1, the bottle mouth 32 has a second height H2, and the second height H2 is equal to the first height H1.

[0075] Please see Figure 1 and Figure 3 , Figure 3This is a schematic diagram of a container structure with a bottle cap receiving space according to another embodiment of the present invention. A bottle bottom groove 33 is disposed within a recess 313 of the bottle body 31, and the bottle bottom groove 33 includes a top wall 331, an outer wall 332, and a second external thread 333. The top wall 331 is disposed at the top of the recess 313. The outer wall 332 is arranged around the bottom of the top wall 331 and forms an encircling space 334 between it and the recess 313. The second external thread 333 is disposed on the outer wall 332. In some embodiments, the bottle bottom groove 33 is conformally formed with the recess 313 of the bottle body 31.

[0076] In some embodiments, the internal thread 11 of the bottle cap 10 can be separably screwed into the first external thread 322 of the bottle mouth 32 or the second external thread 333 of the bottle bottom groove 33. In other words, the bottle cap 10 can be screwed into the first external thread 322 of the bottle mouth 32 through the internal thread 11 of the bottle cap 10 to close the opening 321 of the bottle mouth 32; or the bottle cap 10 can be unscrewed so that the internal thread 11 of the bottle cap 10 is not screwed into the first external thread 322, thereby separating the bottle cap 10 from the bottle mouth 32 and opening the opening 321 of the bottle mouth 32. In the embodiment where the light-emitting component 20 is disposed on the bottle mouth portion 32 and the bottle body 31 includes an optical pattern 315, since the optical pattern 315 on the bottle body 31 forms a multi-faceted refractive surface and the light-emitting unit 25 is disposed in the direction of the recess 313, when the light-emitting unit 25 is turned on, the light source of the light-emitting unit 25 enters the bottle body 31 and is dispersed and reflected by the optical pattern 315 to produce a ripple-like or geometric pattern projection on any surface (e.g., including but not limited to tabletops and walls).

[0077] In other embodiments, the bottle cap 10 can be screwed into the second external thread 333 of the bottle bottom groove 33 via its internal thread 11, so that the bottle cap 10 is accommodated in the recess 313 of the bottle body 31; alternatively, the bottle cap 10 can be unscrewed so that its internal thread 11 is not screwed into the second external thread 333, thereby separating the bottle cap 10 from the recess 313 of the bottle body 31. In embodiments where the bottle cap 10 is accommodated in the recess 313 of the bottle body 31 and the bottle body 31 includes an optical pattern 315, since the light-emitting unit 25 faces the bottle mouth 32 and the optical pattern 315 on the bottle body 31 forms a multi-faceted refractive surface, when the light-emitting unit 25 is turned on, the light source of the light-emitting unit 25 enters the bottle body 31 and is dispersed and reflected by the optical pattern 315 to produce a ripple-like or geometric pattern projection 40.

[0078] In some embodiments, the bottle cap 10 has a first height H1, and the bottle bottom recess 33 has a depth D, wherein the first height H1 is less than or equal to the depth D. In some embodiments, the depth D of the bottle bottom recess 33 is measured from the bottom surface of the top wall 331 of the bottle bottom recess 33 to the bottom surface 314 of the bottle body 31. In other words, when the internal thread 11 of the bottle cap 10 is screwed into the second external thread 333 of the bottle bottom recess 33, the outer top wall 121 of the bottle cap 10 is coplanar with the bottom surface 314 of the bottle body 31, or the outer top wall 121 of the bottle cap 10 is slightly higher than the bottom surface 314 of the bottle body 31. In this way, when the bottle cap 10 is received in the recess 313 of the bottle body 31, the outer top wall 121 of the bottle cap 10 will not exceed the bottom surface 314 of the bottle body 31, thus allowing the bottle body 31 to remain upright and not tilted when placed on a table.

[0079] like Figure 1 As shown, in some embodiments, the annular wall 13 has a first width W1, and the surrounding space 334 between the outer wall 332 and the recess 313 has a second width W2, wherein the first width W1 is less than or equal to the second width W2. In other words, the bottle cap 10 is detachably screwed into the second external thread 333, and the annular wall 13 of the bottle cap 10 is movably disposed in the surrounding space 334. In this way, when the bottle cap 10 is screwed into the bottle body 31 through the internal thread 11 of the bottle cap 10 and the first external thread 322, the surrounding space 334 leaves a certain clearance between the annular wall 13 of the bottle cap 10 and the bottle body 31, and this clearance can accommodate the annular wall 13, so as to ensure the smoothness and reliability of the engagement when the bottle cap 10 is screwed in and out.

[0080] In some embodiments, the first external thread 322 has a first lead, and the second external thread 333 has a second lead, and the number of second leads is less than the number of first leads. In some embodiments, the number of second leads is at least half the number of first leads. Herein, "lead" refers to the distance a helix travels axially in one revolution. In other words, lead is the straight-line distance of one revolution of the helix. Thus, when the internal thread 11 of the cap 10 engages with the second external thread 333 of the bottle bottom groove 33 a certain number of turns (e.g., 1 to 2 turns, such as 1, 1.5, or 2 turns), sufficient engagement force is generated to maintain fixation without the need for additional turns of thread. This reduces production costs.

[0081] Furthermore, when the light source is farther away from the optical pattern 315, the projection 40 of the ripple-like or geometric pattern edges becomes larger, the edges become blurred and the contrast decreases, and the pattern of the projection 40 becomes softer and more diffused. When the light-emitting unit 25 is closer to the optical pattern 315 of the bottle body 31, the edges of the ripple-like or geometric pattern of the projection 40 become sharper and the contrast becomes stronger, and the size of the projection 40 also decreases, that is, the pattern details of the projection 40 are clearer. For example, when the first height H1 is less than the depth D, the light-emitting unit 25 is closer to the optical pattern 315 of the bottle body 31, so the pattern details of the projection 40 in this embodiment are clearer.

[0082] In some embodiments, the color of the bottle cap 10 includes, but is not limited to, transparent colorless, white, red, orange, yellow, green, blue, indigo, purple, black, and other colors. In some embodiments, the color of the bottle body 31 includes, but is not limited to, transparent colorless, white, red, orange, yellow, green, blue, indigo, purple, black, and other colors. When the light-emitting unit 25 itself emits white light, when the light passes through or is reflected by the bottle cap 10 and / or bottle body 31 with a specific color, different wavelengths of light are selectively filtered due to the absorption and scattering characteristics of the material, ultimately making the observed light color the same as the color of the bottle cap 10 and / or bottle body 31.

[0083] In summary, the container structure with a cap receiving space provided by this utility model provides a receiving space at the bottom of the bottle body, so that the cap can be inverted onto the external thread at the bottom of the bottle body through the internal thread of the cap to store the cap, thereby solving the problem that the cap is easily lost or dirty after being removed, and improving the convenience of use.

[0084] Furthermore, this embodiment of the invention incorporates a light-emitting component housed within the bottle cap, thereby adding illumination to the same container without the need for an external lamp holder or circuitry. Additionally, this illumination function can be aesthetically enhanced by designing different light-emitting units with varying colors, as well as the color of the bottle cap and / or the bottle itself.

[0085] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Anyone skilled in the art may make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
