DETAILED DESCRIPTION OF THE EMBODIMENTS

[0049] In the following description, numerous specific details are provided to offer a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the invention can be implemented without one or more of these details. In other examples, some well-known technical features have not been described to avoid confusion with the present invention.

[0050] Unless independently defined and indicated, the directions such as up, down, left, right, front, back, inner, and outer mentioned in this document are all based on the up, down, left, right, front, back, inner, and outer directions shown in the figures of this invention. This is hereby stated collectively.

[0051] This embodiment discloses a sliding sealed bottle cap as shown in FIGS. 1 to 15:

[0052] FIG. 1 shows an exemplary sliding sealed bottle cap 100. The sliding sealed bottle cap 100 generally includes a main lid 110 and a sealing sliding sub-cap 150, which is configured to move between open and closed positions to selectively open or close the liquid opening 112. FIG. 1 shows an isometric view of the exemplary sliding sealed bottle cap 100, with the sealing sliding sub-cap 150 in the open position on container 105. FIG. 2 shows an isometric view of the exemplary sliding sealed bottle cap 100, with the sealing sliding sub-cap 150 in the closed position on a container 105. FIG. 3 shows a cross-sectional view of the sliding direction of the exemplary sliding sealed bottle cap in the closed position. FIG. 4 shows a cross-sectional view of the locking direction of the exemplary sliding sealed bottle cap in the closed position. FIG. 5 shows an isometric view of an exemplary container 105 for receiving the main lid 110. The main lid 110 may also include a sidewall 114, which may define a groove 116 for placing a gasket (not shown) that provides a seal between the sliding sealed bottle cap 100 and the container 105. However, as will be discussed below, other sealing methods for sealing the main lid 110 to the container 105 are also anticipated. The main lid 110 may also include a flange 118 for engaging the opening 107 of the container 105. The flange 118 may also include a top wall 120 and an optional lid tab 122 extending from the top wall 120 to help users remove the sliding sealed bottle cap 100 from the container 105.

[0053] FIG. 6 shows an isometric top perspective view of the main lid 110 in the exemplary sliding sealed bottle cap. FIG. 7 shows a top view of the main lid in the exemplary sliding sealed bottle cap of FIG. 1, with the sealing sliding sub-cap 150 removed. As shown in FIG. 6, the main lid 110 may also include a middle wall 124 extending below the flange 118. The middle wall 124 may define a recess 126 for receiving the sealing sliding sub-cap 150. FIG. 9 shows a longitudinal cross-sectional view of the main lid in the exemplary sliding sealed bottle cap. The recess 126 and middle wall 124 may form intermediate guide walls 123a and 123b, including two looped guide rails 134a and 134b. The open or closed position determines the specific locations of positioning points 159a, 159b, 159c, and 159d. This allows the sealing sliding sub-cap 150 to be selectively locked in the open or closed position during use, which also prevents the sealing sliding sub-cap 150 from unintentionally moving in the guide channel 127 and the two looped guide rails 134a and 134b. Specifically, the recess 126 may define a guide channel 127 and looped guide rails 134a and 134b for the sealing sliding sub-cap 150 to move between the open and closed positions. As shown in FIG. 7, the opening 112 for drinking or pouring liquid from the container may also be formed in the recess 126.

[0054] The recess 126 and middle wall 124 of the main lid 110 may include two looped guide rails 134a, 134b and positioning points 159a, 159b, 159c, 159d. These positioning points, the two looped guide rails 134a, 134b, and guide groove 127 are configured to allow the sealing sliding sub-cap 150 to travel along the guide channel 127, with the spring sliding positioning bead moving along the two looped guide rails 134a, 134b from the closed position to the open position of the sealing sliding sub-cap, locking over positioning points 159b, 159d. Conversely, they allow the sealing sliding sub-cap 150 to travel along the guide channel 127 and the spring sliding positioning bead along the two looped guide rails 134a, 134b from the open position to the closed position of the sealing sliding sub-cap, locking over positioning points 159a, 159c.

[0055] Additionally, the recess 127 of the main lid 110 may include one or more ventilation holes 132a, 132b, which provide an air inflow channel during liquid pouring from the container. The flow rate of the ventilation holes meets the user's needs, and their size can be further adjusted as required. As will be discussed in more detail below, depending on the position of the sealing sliding sub-cap relative to the main lid 110, the first ventilation hole 132a and the second ventilation hole 132b can be selectively opened and closed by the sealing sliding sub-cap 150.

[0056] As also shown in FIG. 6, the main lid 110 may include a rear arc 129 within the channel 127. The rear arc 129 may be located on the rear wall of the channel 127. The rear arc 129 provides a stopping action for the sealing sliding sub-cap 150, allowing the sealing sliding sub-cap 150 to be near the rear arc 129 when in the fully open position. In this manner, a gap can be formed between the sealing sliding sub-cap 150 and the rear wall of the channel 127, and when any liquid is present in the channel 127, this gap can help prevent displacement of liquid within the channel 127. This, in turn, helps prevent the sealing sliding sub-cap from moving to the open position to avoid splashing liquid from the channel 127 onto the user.

[0057] As can be seen in FIG. 8 (which is a cross-sectional view of the main lid 110), the middle wall 124 may extend at a certain angle relative to the top wall 120 and side wall 114. This allows the opening 112 for pouring liquid from the container to be positioned at a height below the flange 118.

[0058] FIG. 11 shows an isometric top view of the sealing sliding sub-cap 150 in the exemplary sliding sealed bottle cap of FIG. 1. FIG. 12 shows an isometric bottom view of the sealing sliding sub-cap in the exemplary sliding sealed bottle cap of FIG. 1. FIG. 13 shows a top view of the sealing sliding sub-cap in the exemplary sliding sealed bottle cap of FIG. 1. FIG. 14 shows a cross-sectional view of the sealing sliding sub-cap in the exemplary sliding sealed bottle cap of FIG. 1. As discussed herein, the sealing sliding sub-cap 150 may generally include a sealing sliding sub-cap body 155 with handles 152a and 152b, elastic sliding positioning components 157a, 157b, 157c, and 157d. It is composed of a total of 5 parts (of course, the number of elastic sliding positioning components can be reduced or increased).

[0059] As shown in FIG. 3, the sealing sliding sub-cap 150 may have two symmetries, allowing it to be placed in the main lid 110 in two different orientations. This eliminates user errors when installing the sealing sliding sub-cap 150 onto the main lid 110.

[0060] As shown in FIG. 14, the sealing sliding sub-cap body 155 may include two symmetrical flanges 151a and 151b, both configured to selectively cover and seal the opening 112 for pouring liquid from the container. Tabs or handles 152a and 152b are designed for users to grip to selectively move the sealing sliding sub-cap 150 to the open position, exposing the opening 112 on the main lid 110, or to the closed position, covering the opening 112 on the main lid 110. Handles 152a and 152b may include two inwardly tapered partial arc surfaces 153a and 153b for gripping purposes, as well as an operating plane 161. Handle 152a and flange 151a curve inward towards the center to form a concave surface 154a for gripping the handle, while handle 152b and flange 151b curve inward towards the center to form a concave surface 154b. These two surfaces, 154a and 154b, are designed to provide users with a better experience when gripping to selectively move the sealing sliding sub-cap. The sealing sliding sub-cap body 155 has a total of 4 fixed holes 156a, 156b, 156c, and 156d for fixing the elastic sliding positioning beads 157a, 157b, 157c, and 157d. The sealing sliding sub-cap body 155 has symmetry, allowing the sealing sliding sub-cap 155 to be placed and gently pressed onto the lid in different orientations.

[0061] FIG. 14 shows a cross-sectional view of the sealing sliding sub-cap in the exemplary sliding sealed bottle cap of FIG. 1. The sealing sliding sub-cap 150 may have tapered ends 164a and 164b, which also create a smaller contact area between the sealing sliding sub-cap 150 and the channel, thus reducing the amount of splashing of any contents in the channel 127 of the main lid 110.

[0062] As shown in FIG. 3, due to the angle of the channel 127, liquid tends to travel down the slope of the channel 127 and collect near the opening 112 in the lid 110. This can be particularly helpful near the lid's opening, reducing splashing of contents near the opening of the main lid 110 when the user closes the main lid 110 with the sealing sliding sub-cap 150.

[0063] FIG. 12 (a rear perspective view of the sealing sliding sub-cap 150) shows the reverse structures 162 and 163 of the two symmetrical flanges 151a and 151b of the exemplary sealing sliding sub-cap 150 that cover the opening 112 of the main lid 110, as well as the recessed airflow channel 158 between them. The formation of the recessed airflow channel 158 is beneficial for air circulation through the ventilation holes 132a and 132b when the opening 112 of the main lid 110 is in the open position. Residual liquid attached near the channel will also be mostly drawn into the container during liquid pouring due to the airflow from the ventilation holes. It can also reduce splashing of the contents in channel 127 when the sealing sliding sub-cap 150 covers the opening 112 of the main lid 110 or when pushing the sealing sliding sub-cap 150 closer to the rear arc surface 129 of the recess 127 to open the opening 112. A gap is formed between the side walls 123a and 123b of the channel 127 and the sealing sliding sub-cap 150, with the cross-sectional area of the airflow channel in the gap being larger than that of the ventilation holes, ensuring smooth air passage between the interior and exterior.

[0064] FIG. 7 (cross-sectional view of the elastic positioning bead) shows the construction of the elastic positioning bead 157, which is mainly composed of 3 parts, including an outer shell 180, a sliding ball 181, and a stainless steel spring 182. The elastic positioning bead 157 serves as a standard part, with the sliding ball 181 being pre-compressed by the stainless steel spring 182, ensuring that the sliding ball 181 be fixed in the center of the outer shell 180. When the outer shell 180 is fixed, the sliding ball 181 will contract and extend within the elastic range of the stainless steel spring when subjected to varying compression forces. This ensures that the sliding ball 181 is always in contact with and compressed by the stainless steel spring 182, causing the sliding ball 181 to be pushed outward along its axis, attempting to return to its initial pre-compressed state.

[0065] To operate the sealing sliding sub-cap 150, the user can move it from the open position to the closed position by gripping handle 152a, handle 152b, or both simultaneously. The sealing sliding sub-cap 150 moves along the guide channel 126 and the two looped guide rails 134a and 134b, allowing the sealing surface 162 or 163 of the sub-cap body 155 to cover the opening 112 and ventilation holes 132a and 132b of the main lid 110. Conversely, the user can move the sealing sliding sub-cap 150 from the closed position to the open position by gripping handle 152a, handle 152b, or both simultaneously. The sealing sliding sub-cap 150 moves along the guide channel 126 and the two looped guide rails 134a and 134b, allowing the sealing surface 162 or 163 of the sub-cap body 155 to move away from the opening 112 and ventilation holes 132a and 132b of the main lid 110. This helps prevent the container's contents from spilling out.

[0066] Additionally, for cleaning purposes or if the user does not want the sealing sliding sub-cap 150 on the main lid 110, it can be selectively removed from the main lid 110 (with an operating force between 0.5-5N). To remove the sealing sliding sub-cap 150 from the main lid 110, from the underside of the sliding sealed bottle cap 100, the user can grip handles 152a and 152b on the sealing sliding sub-cap 150 and pull the sealing sliding sub-cap 150 outward. This cause the sliding positioning beads 157a, 157b, 157c, and 157d to disengage from the first guide rail 134a and the second guide rail 134b, allowing the user to thoroughly clean the main lid 110 when the sealing sliding sub-cap 150 is removed from the main lid 110.

[0067] To replace the sealing sliding sub-cap 150 onto the main lid 110, position the sealing sliding sub-cap 150 near the guide groove of the main lid 110, and align it with the direction of guide rails 134a and 134b. Use your thumb to press on the surface 158 of the sealing sliding sub-cap. Under the pressure from the thumb and guided by the rounded corner 125 of the groove, the sliding positioning beads 157a, 157b, 157c, and 157d will smoothly fall into the first guide rail 134a and the second guide rail 134b (with an operating force between 0.5-5N). This secures the sealing sliding sub-cap 150 in the proper position on the main lid 110. Due to the symmetry of the sealing sliding sub-cap 150, it can be placed on the main lid in two different orientations.

[0068] When the sealing sliding sub-cap 150 is maintained in the closed position, and pressure from the liquid acts on the sealing surface 162 or 163 through the opening and ventilation holes of the main lid 110, the sealing sliding sub-cap 150 is supported within the guide rails 134a and 134b by the pressure generated from the compression of four elastic positioning beads. The direction of the preload force from the elastic positioning beads between the sealing sliding sub-cap 150 and the main lid 110 is normal to the direction of the force from the pressure of an inverted filled container. Therefore, the preload force of the elastic positioning beads between the sealing sliding sub-cap 150 and the main lid 110 can more easily resist the force from the pressure of an inverted filled container. In this manner, in the example of FIG. 2, the force produced by the interaction of the four elastic positioning beads can be between 8N to 20N. Additionally, the preload elastic tension can be designed so that in the case of hot and/or pressurized liquids, if the internal gas pressure becomes too high, the sealing sliding sub-cap 150 may slightly contract, ultimately pushing open the air passage channel for ventilation. Unlike fully sealed non-venting/leak-proof lids or press-fit lids on containers, this is desirable because when encountering highly pressurized liquids, it allows the press-fit lid to be less likely to completely detach from the container, allowing for the release of pressure generated by highly pressurized liquids inside. In the example of FIG. 2, the preload force on the lid provided by the sliding positioning beads can be designed to be less than the retention force of the gasket between the main lid and the container. For example, the main lid 110 can be retained on the container by a first force, and the sealing sliding sub-cap 150 can be retained on the lid by a second force, with the first force being greater than the second force, ensuring that the sealing sliding sub-cap will release from the main lid before the lid releases from the container. In this way, the preload force on the lid provided by the sliding positioning beads can be less than the retention force of the gasket between the lid and the container, allowing the sealing sliding sub-cap to vent before the gasket, thus preventing rapid overflow from the container.

[0069] Additionally, the surface roughness of the lid area interacting with the sealing sliding sub-cap 150 can be adjusted according to the amount of feedback desired by the user. For example, the surface roughness of the lid area interacting with the sealing sliding sub-cap 150 can be reduced to allow the user to easily manipulate the sealing sliding sub-cap 150 from the closed position to the open position and from the open position to the closed position during product use.

[0070] The sealing sliding sub-cap may also include a channel, and when the sealing sliding sub-cap is in the open position, the channel can be configured to essentially align with the ventilation holes. The sealing sliding sub-cap may also include features that continue to form a ventilation channel with the first side wall and the second side wall of the main lid. This ensures that the entire air passage remains unobstructed. When the sealing sliding sub-cap is in the closed position, the reverse structures 162 and 163 of the sealing sliding sub-cap precisely seal the opening 112 and ventilation holes 134a and 134b of the main lid 110. This helps prevent the contents of the container from spilling out.

[0071] It can also be anticipated that the guide rails of the lid and the sliding positioning beads of the sub-cap can be designed in reverse.

[0072] The invention has been disclosed in the above references to various examples in the accompanying drawings. However, the purpose of this disclosure is to provide examples of various features and concepts related to the invention, not to limit the scope of the invention. Skilled artisans in the relevant field will recognize that many variations and modifications can be made to the above examples without departing from the scope of the invention.

Molding Process and Assembly Method

[0073] To form the main lid 110 can be produced using an injection molding process, where the main body 110A of the main lid can be injection molded with a single shot of polymeric material.

[0074] To form the sub-cap, sub-cap 155 can be produced using an injection molding process, where the main body 155 of the sub-cap can be injection molded with a single shot of polymeric material.

[0075] To form the complete sub-cap 150, the sub-cap body 155 and the elastic sliding positioning bead assemblies are press-fitted together with an interference fit. The interference amount can ensure that the sub-cap and elastic sliding positioning bead assemblies can withstand 3,000 cycles of repeated impact tests at temperatures ranging from 80 C. to 30 C. without detachment.

Example Embodiment

[0076] A sliding sealed bottle cap including: a flange for engaging the opening of a container, the flange defining a top wall and a lid tab extending from the top wall; a sidewall defining a groove for placing a gasket; a middle wall extending below the flange, the middle wall defining a recess, the recess sidewall having a first guide rail, a second guide rail, positioning points for locating a sealing sliding sub-cap, and configured for unobstructed ventilation holes; the sealing sliding sub-cap configured to selectively provide a closed position by covering the opening and an open position by pushing the sealing sliding sub-cap backward, the sealing sliding sub-cap including a sealing sliding sub-cap tab, a first elastic positioning bead, a second elastic positioning bead, a third elastic positioning bead and a fourth elastic positioning bead, and one or more handles of the sealing sliding sub-cap.

[0077] Herein the sealing sliding sub-cap also includes a channel, and wherein when the sealing sliding sub-cap is in the open position, the channel is configured for unobstructed ventilation holes.

[0078] Herein the ventilation channel is formed on the bottom surface of the sealing sliding sub-cap. Adjacent air passages are formed in the gap between the sidewalls of the guide groove and the sidewalls of the sliding sub-cap. When the user operates the lid, the residual contents in the channel can be drawn in through the ventilation holes, reducing splashing when the sub-cap is closed during use.

[0079] Herein the elastic positioning beads are fixed and have internal pre-compression, and wherein the sliding ball moves inward when subjected to compression.

[0080] Herein the sealing sliding sub-cap has symmetry, allowing it to be placed on the sliding sealed bottle cap in different orientations.

[0081] Alternatively, the positioning points could be omitted, relying solely on the preload force and pre-compression of the elastic sliding positioning beads for positional locking (the positioning points are prioritized in the description of this invention, but where positioning points are mentioned, they can be substituted with the preload force and pre-compression of the elastic sliding positioning beads for positional locking).

[0082] A method of use the sliding sealed bottle cap, including the following steps S1 to S6. [0083] S1: The sealing sliding sub-cap slides along the guide groove and looped guide rail on the main lid via the handle. When pushed forward to the front of the first positioning point, the elastic sliding positioning bead interacts with the positioning points, keeping the sealing sliding sub-cap in the closed position and preventing it from moving backward freely. [0084] S2: When the sealing sliding sub-cap is pushed backward to behind the second positioning point, the elastic sliding positioning bead interacts with the positioning points, keeping the sealing sliding sub-cap in the open position and preventing it from moving forward freely, and the sealing sliding sub-cap is locked in either the open or closed position, preventing accidental movement. [0085] S3: The sealing sliding sub-cap is removed from the main lid by the user via the handle. After cleaning, the sealing sliding sub-cap can be reinstalled onto the main lid by placing it near the guide groove and pressing it back into the guide groove and looped guide rail. [0086] S4: The sealing sliding sub-cap moves between the closed and open positions. When in the closed position, it covers the opening of the main lid to prevent contents from spilling out. When in the open position, it exposes the opening to allow the contents to be consumed. [0087] S5: The sealing sliding sub-cap tapers at each end, reducing the contact area between the ends and the channel, helping to prevent the displacement of liquid in the channel.
