Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, and in particular to a threaded cap for sealing bottle caps that allow for immediate mixing of drinks. Background Technology

[0002] Many bottled beverages for separate storage use a puncture and burst structure, which is highly questionable, especially the small plastic particles that are ejected when the cap bursts, which does not meet the requirements of healthy beverages. Threaded cap sealing is a very mature sealing technology. Replacing the puncture cap with a threaded cap not only solves the stringent requirements of bottle injection molding, but also eliminates the plastic particles generated when the cap is punctured and burst open.

[0003] Currently, most pre-mixed beverages on the market use puncture and tear-sealed caps for storage, while a small number use aluminum film seals. The most mature sealing method on the market is the threaded cap. However, it is very difficult to use a threaded cap for pre-mixed beverage bottles, and such products are extremely rare on the market. In order to seal pre-mixed beverages better, make them healthier to drink, and make them easier to open, we have developed a pre-mixed beverage bottle with a double threaded cap.

[0037] Example

[0038] This embodiment provides a threaded cap for sealing bottle caps used for immediate drinking and mixing, such as... Figures 1 to 14 As shown, it includes a container 100, an inner lid 200, and an outer lid 300.

[0039] The container 100 is used to store mixed materials. The top opening of the container 100 is a first bottle neck 106, and an outer cap 300 is threaded onto the top of the container 100 to close the top opening. The bottom opening of the container 100 is closed by a first cover plate 101. A water bottle cap, coaxial with the first cover plate 101, is connected below the first cover plate 101. A bottle cap for bottled water can be threaded onto the water bottle cap. A discharge port 110 is provided in the middle of the first cover plate 101, serving as a communication channel between the container 100 and the bottled water connected below. A sealing ring 109 is provided below and around the discharge port 110. When connecting bottled water, the sealing ring 109 can be inserted into the bottle neck to ensure a tight seal. A second bottle neck 102 extends upward from the discharge port 110.

[0040] Preferably, the water bottle cap includes a coaxial first water bottle cap and a second water bottle cap. The inner wall of the first water bottle cap is provided with a second internal thread 107 adapted for use with a 38mm large-diameter water bottle, and the inner wall of the second water bottle cap is provided with a third internal thread 108 adapted for use with a 30mm small-diameter water bottle. A first sealing gasket placement area 111 is located at the bottom of the first cover plate 101 and between the first and second water bottle caps for placing a sealing gasket. A second sealing gasket placement area 112 is located at the bottom of the first cover plate 101 and between the second water bottle cap and the sealing retaining ring 109, also for placing a sealing gasket. The sealing gaskets increase the sealing performance between the container 100 and the water bottle.

[0041] It should be noted that during manufacturing, manufacturers can choose to retain one of the bottle caps. By retaining the first cap and removing the second, the product can be used with 38mm wide-mouth water bottles. Similarly, by retaining the second cap and removing the first, the product can be used with 30mm narrow-mouth water bottles. By adding anti-theft and detachable rings to the bottom of both caps, the manufacturer can combine them with the water bottle to create a complete product for customer convenience. Alternatively, the anti-theft and detachable rings can be omitted, and the product can be sold independently. Customers can then use it in conjunction with commercially available bottled water. As an independent product, its small size and light weight make it more suitable for e-commerce shipping.

[0042] The inner cover 200 is nested inside the container 100 and is used to control the opening and closing of the discharge port 110 and to seal the material inside the container 100. Specifically, the inner cover 200 includes a coaxial first cylinder 207 and a second cover plate 201. The second cover plate 201 is connected to the bottom of the first cylinder 207, and an inner cover wall 204 surrounds the outer edge of the second cover plate 201. The inner cover 200 is inserted into the container 100, and the inner cover wall 204 is threadedly connected to the container 100, thereby allowing adjustment of the vertical position of the inner cover 200 inside the container 100, and thus controlling the opening or closing of the discharge port 110. To enhance the sealing performance between the inner cover 200 and the discharge port 110, an expansion sealing ring 211 and a wrapping sealing ring 210 are sequentially arranged at the bottom of the second cover plate 201 from the center outwards. After the inner cap 200 is inserted into the container 100, the expansion sealing ring 211 can be embedded in the inner wall of the second bottle opening 102, while the wrap-around sealing ring 210 wraps around the outer wall of the second bottle opening 102, thereby achieving a double seal on the second bottle opening 102. A first discharge hole 202 and a second discharge hole 203 are provided on the second cover plate 201, located around the expansion sealing ring 211. When the inner cap 200 is rotated to a specific position, one of the first discharge hole 202 or the second discharge hole 203 will align with the discharge port 110, allowing the material in the container 100 to enter the water bottle through the discharge port 110 and the discharge hole, completing the mixing process. A radially distributed capping assembly 209 is provided at the top center of the second cover plate 201. The capping assembly 209 includes multiple forked branches, facilitating the user to rotate the inner cap 200 using tools.

[0043] Preferably, the bottom inner wall of the container 100 is provided with a first internal thread 105, and the inner cover wall 204 is provided with a second external thread 205 adapted to the first internal thread 105. The connection between the first internal thread 105 and the second external thread 205 allows the inner cover 200 to be connected inside the container 100, and the inner cover 200 can be moved up and down by rotating the threads. On the outer side of the top of the container 100, i.e., the outer wall 103, a first external thread 104 is provided for threaded connection with the outer cover 300. Preferably, the outer wall of the first cylinder 207 is provided with first one-way linkage teeth 208. The outer cover 300 includes a third cover plate 301 and a second cylinder 302. The second cylinder 302 is connected to the bottom of the third cover plate 301. The diameter of the second cylinder 302 is smaller than that of the first cylinder 207. When the outer cover 300 is installed on the top of the container 100, the second cylinder 302 is nested inside the first cylinder 207. The inner wall of the second cylinder 302 is provided with a second one-way linkage tooth 306 that is adapted to the first one-way linkage tooth 208. So when the user unscrews the outer cover 300, the second one-way linkage tooth 306 engages with the first one-way linkage tooth 208, causing the inner cover 200 to rotate synchronously. The inner cover 200 moves upward, and the discharge hole aligns with the discharge port 110. The material automatically falls into the water bottle, realizing the linkage effect of opening the outer cover 300 to start mixing, simplifying the operation. When the user tightens the outer cover 300, the one-way tooth slips, and the outer cover 300 only rotates and tightens itself without driving the inner cover 200, thus avoiding the inner cover 200 from being accidentally closed.

[0044] Preferably, the edge of the third cover plate 301 is surrounded by an annular cover wall 304, and the inner wall of the cover wall 304 is provided with a fourth internal thread 305 that is adapted to the first external thread 104, so that the outer cover 300 can be connected to the top of the container 100 through the threaded connection of the first external thread 104 and the fourth internal thread 305. A sealing ring 303 is provided below the third cover plate 301 and between the second cylinder 302 and the cover wall 304 to increase the sealing performance between the outer cover 300 and the container 100.

[0045] Preferably, the top of the inner cover wall 204 is uniformly provided with outwardly extending expansion friction plates 206. When the inner cover 200 is nested inside the container 100, the expansion friction plates 206 are tightened with the inner wall of the container 100, thereby ensuring that the inner cover 200 can be stably stuck inside the container 100 and will not easily rotate and fall off.

[0046] Preferably, the diameter of the first cylinder 207 is smaller than the diameter of the first discharge hole 202 and larger than the diameter of the second discharge hole 203, so different discharge holes can be exposed by moving the inner cover 200 up and down.

[0047] Factory assembly method: The factory uses special equipment to probe into the first cylinder 207, clamp the cap assembly 209, and place the inner cap 200 into the container 100 and rotate it clockwise so that the second external thread 205 interacts with the first internal thread 105, causing the inner cap 200 to penetrate deeper into the container 100. At the same time, the expansion sealing ring 211 is squeezed into the inner wall of the second bottle mouth 102 to achieve a sealing effect, and the wrapping sealing ring 210 also wraps around the outer wall of the second bottle mouth 102 to further seal. At this time, the inner cap 200 and the container 100 are assembled, and the discharge port 110 is tightly sealed.

[0048] Factory filling method: Honey and concentrated fruit juice are poured into the composite body of the assembled inner cap 200 and container 100. Through the interaction of the fourth internal thread 305 and the first external thread 104, the outer cap 300 is covered on the top of the first bottle mouth 106 of the container 100. The sealing ring 303 is squeezed into the inner wall of the first bottle mouth 106 to achieve a sealing effect. At this time, the product filling is completed.

[0049] Usage and working principle: When a customer receives the product, they combine it with a 38mm or 30mm diameter bottle of water via the second internal thread 107 or the third internal thread 108. The soft rubber pad at the first sealing gasket placement 111 or the soft rubber pad at the second sealing gasket placement 112, through the mutual compression of the threads, combines with the bottle opening to achieve a seal, preventing water leakage. Because bottle openings from different manufacturers may have slight differences, a soft rubber pad is used for sealing, which can better adapt to non-standard bottle openings on the market. When combined with bottled water, customers open the outer cap 300 counterclockwise, just like opening a regular bottle of water. As the outer cap 300 is turned, the second cylinder 302 also rotates. The second one-way linkage tooth 306 interacts with the first one-way linkage tooth 208, causing the inner cap 200 to be screwed open upwards inside the container 100. At the same time, the expansion sealing ring 211 and the wrap-around sealing ring 210 disengage from the second bottle opening 102, clearing the obstruction to the discharge port 110. At this point, the honey and concentrated fruit juice packaged inside the container 100 flow smoothly... The first discharge hole 202 and the second discharge hole 203 flow into the bottled water through the discharge port 110. The customer then tightens the outer cap 300 clockwise, shakes the honey in the bottled water evenly, and opens the outer cap 300 to enjoy freshly mixed, healthy honey water. When the outer cap 300 is opened, the inner cap 200 is secured by an expansion friction plate 206 larger than the inner wall diameter of the container 100, preventing it from falling off and contaminating the environment. If the customer doesn't finish the mixed honey water at once, they can tighten the outer cap 300 again to save it for later. When the outer cap 300 is tightened, the inner cap 200 will also rotate, but since there are no threads on the inner cap, it will only rotate freely, neither affecting the tightening nor the opening of the outer cap 300.

[0050] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
