Description

Technical Field

[0001] This utility model relates to the field of bottle cap technology, and in particular to a soy sauce bottle cap. Background Technology

[0002] Soy sauce bottle caps are sealing caps on soy sauce bottles to prevent oxidation and spoilage. However, the nature of soy sauce itself causes it to produce fermentation gases during long-term storage. When these gases accumulate inside the cap, opening the cap not only produces noise from the gas release but also releases an unpleasant odor, both of which negatively impact the user experience.

[0003] In existing technologies, soy sauce bottle caps focus on their sealing performance, but few methods are available to eliminate or release the fermentation gases produced by soy sauce. Therefore, how to remove fermentation gases while ensuring basic sealing performance has become a problem that needs to be solved. Utility Model Content

[0004] The purpose of this invention is to provide a soy sauce bottle cap in which fermentation gases generated during storage are discharged through the through-hole on the cap. The gas is also slowly discharged, filtered, and adsorbed through the barrier effect formed by the filter layer. This can prevent the fermentation gases from accumulating in the soy sauce bottle for a long time due to the cap not being opened, and prevent the gas from rushing out when the cap is opened.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a soy sauce bottle cap, comprising:

[0006] The lower cap is mounted on the soy sauce bottle, and its lower and upper side walls are respectively provided with a first outer edge and a second outer edge.

[0007] The upper cover includes a bottom ring and a flip cover hinged to the bottom ring. The inner wall of the bottom ring has a step. The upper end of the flip cover has a through hole penetrating its body, and the flip cover has an annular groove located beside the through hole. The bottom ring is fitted onto the lower part of the lower cover, and the step abuts against the lower end of the first outer edge. The flip cover is fitted onto the upper part of the lower cover, and the second outer edge is interference-fitted into the annular groove.

[0008] A filter layer is disposed inside the flip cover and covers the through hole.

[0009] Preferably, the diameter of the through hole is 0.5-2.5 mm, and the diameter of the filter layer is 5-15 mm.

[0010] As a further optimization, a limiting ring is provided inside the flip cover next to the through hole, and the filter layer is disposed on the limiting ring and abuts against the flip cover.

[0011] As a further optimization, a limiting ring is provided inside the flip cover next to the through hole, and the filter layer is disposed on the annular plane of the limiting ring, forming a buffer cavity that communicates with the through hole between the filter layer and the flip cover.

[0012] As a further optimization, the bottom end of the limiting ring is positioned higher than the fixed point of the lower cover.

[0013] As a further optimization, the filter layer is filter cotton, but other food-grade materials with filtration and adsorption properties can also be selected.

[0014] As a further optimization, the flip cover includes a connecting piece and a cover body. The cover body is provided with a clearance opening. The connecting piece extends into the clearance opening and its upper and lower ends are respectively connected to the cover body and the bottom ring. There are gaps between the opposite sides of the connecting piece and the side walls of the clearance opening.

[0015] As a further optimization, the cover body is provided with a groove on the side opposite to the relief opening, so that the cover body can be opened after the finger is inserted.

[0016] As a further optimization, a bridge is provided between the bottom ring and the flip cover to ensure a stable connection between the upper and lower covers before the soy sauce bottle cap is opened.

[0017] As a further optimization, a sealing sheet is provided on the inner wall of the lower cover.

[0018] As a further optimization, the sealing sheet is provided with a pull ring to facilitate operation of the sealing sheet.

[0019] As a further optimization, the sealing sheet is provided with auxiliary holes and an auxiliary filter layer, the auxiliary filter layer covering the auxiliary holes.

[0020] Compared with the prior art, the present invention has the following beneficial effects: the fermentation gas generated by soy sauce during storage can be discharged through the through hole on the flip-top, and can be slowly discharged, filtered and adsorbed through the barrier effect formed by the filter layer, which can avoid the long-term accumulation of fermentation gas in the soy sauce bottle caused by not opening the soy sauce bottle cap for a long time, and avoid the phenomenon of gas rushing out when the flip-top is opened.

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figures 1 to 4 As shown, a soy sauce bottle cap includes a lower cap 10, an upper cap 20, and a filter layer 30. The lower cap 10 is disposed on a soy sauce bottle (not shown), and its lower and upper sidewalls are respectively provided with a first outer edge 1a and a second outer edge 1b. The upper cap 20 includes a bottom ring 21 and a flip cap 22 hinged to the bottom ring 21. The inner wall of the bottom ring 21 is provided with a step 2a. The upper end of the flip cap 22 is provided with a through hole 200 penetrating its body, and the inner part of the flip cap 22 is... An annular groove 2b is provided on the side of the through hole 200. The bottom ring 21 is sleeved on the lower part of the lower cover 10, and the step 2a abuts against the lower end of the first outer edge 1a to position the upper cover 20 on the lower cover 10. The flip cover 22 is sleeved on the upper part of the lower cover 10, and the second outer edge 1b is interference-fitted into the annular groove 2b to achieve a seal between the flip cover 22 and the lower cover 10. The filter layer 30 is preferably filter cotton, which is set inside the flip cover 22 and covers the through hole 200.

[0030] In this invention, the bottom ring 21 (upper cover 20) can be positioned on the lower cover 10 by the mating part of the step 2a and the first outer edge 1a, and the soy sauce bottle cap is sealed by the mating part of the second outer edge 1b and the annular groove 2b. Due to the nature of soy sauce itself, the fermentation gas generated during storage can be discharged through the through hole 200 on the flip cover 22, and can be slowly discharged by the barrier effect formed by the filter layer 30. In addition, the fermentation gas can be adsorbed and filtered to a certain extent by the filter layer 30 during the discharge process. The above process can avoid the fermentation gas in the soy sauce bottle from accumulating for a long time due to the soy sauce bottle cap not being opened for a long time, and can avoid the gas rushing out when the flip cover 22 is opened.

[0031] It should be noted that once the cap of a soy sauce bottle is opened, it will not shake or tip over like a beverage bottle when carried. Soy sauce bottles are generally kept stable, so the soy sauce inside will not spill out through the opening.

[0032] Preferably, a limiting ring 23 is provided inside the flip cover 22 next to the through hole 200. The filter layer 30 is disposed on the limiting ring 23 and abuts against the flip cover 22. The limiting ring 23 can be used to position the filter layer 30 when it is installed. The filter layer 30 can be installed by snapping it into the limiting ring 23, or by coating an adhesive layer on the periphery of the filter layer 30 and then bonding it to the inner wall of the positioning ring 23 and abutting against the flip cover 22.

[0033] like Figure 5 As shown, in another embodiment of this utility model, a limiting ring 23 is provided next to the through hole 200 inside the flip cover 22. The filter layer 30 is disposed on the annular plane of the limiting ring 23 and forms a buffer cavity 230 connected to the through hole 200 between the filter layer 30 and the flip cover 22. In this embodiment, the filter layer 30 does not abut against the flip cover 22, but forms a buffer cavity 230 between the two. The presence of the buffer cavity 230 can filter the fermentation gas out of the soy sauce bottle cap and also prevent air from directly entering the soy sauce bottle cap. In addition, the fermentation gas and air are mixed in the buffer cavity 230 and then dispersed out of the through hole 200. The mixing of the two in the buffer cavity 230 is equivalent to diluting the fermentation gas, which can prevent the fermentation gas with high concentration and strong odor from being directly discharged from the soy sauce bottle cap.

[0034] Preferably, the bottom end of the limiting ring 23 is higher than the top end of the lower cover 10, which can prevent the limiting ring 23 from extending into the lower cover 10.

[0035] Specifically, the flip cover 22 includes a connecting piece 221 and a cover portion 222. The cover portion 222 is provided with a relief opening 220. The connecting piece 221 extends into the relief opening 220, and the upper and lower ends of the connecting piece 221 are respectively connected to the cover portion 222 and the bottom ring 21. There are gaps between the opposite sides of the connecting piece 221 and the side walls of the relief opening 220. The above structure can enable the cover portion 222 to be flipped relative to the connecting piece 221 based on the connection of the connecting piece 221. For example, by bending the connecting piece 221, the flip cover 22 can be flipped to open the soy sauce bottle cap.

[0036] The cover 222 has a groove 2c on the side opposite to the relief opening 220. By inserting a finger into the groove 2c, it is easy to apply external force to flip the cover 22 (i.e., the cover 222).

[0037] Furthermore, initially, a bridge 211 is provided between the bottom ring 21 and the flip cover 22 (i.e., the cover part 222) to ensure the connection stability between the bottom ring 21 and the flip cover 22; when the flip cover 22 is opened, the cover part 222 is stably connected by the interference fit between the annular groove 2b and the second outer edge 1b when the cover part 222 is closed.

[0038] A sealing sheet 111 is provided on the inner wall of the lower cover 10. The sealing sheet 111 is located inside the second outer edge 1b and is lower than the upper end of the second outer edge 1b. It can provide a good sealing effect for the soy sauce before the soy sauce bottle cap is opened for the first time, so as to prevent the soy sauce from overflowing or spilling during transportation or handling, and also prevent the soy sauce from contacting the filter layer. Furthermore, a pull ring 112 is provided on the sealing sheet 111, so that when the soy sauce bottle cap is opened for the first time, it is convenient to insert a finger into the pull ring 112 to pull the sealing sheet 111 and remove it from the lower cover 10.

[0039] like Figure 7 As shown, based on the above configuration, an auxiliary hole (not shown) and an auxiliary filter layer 1111 can be provided on the sealing sheet 111. The auxiliary hole penetrates the sealing sheet 111, and the auxiliary filter layer 111 covers the auxiliary hole. The auxiliary hole has the same structure and function as the through hole 200. It allows fermentation gases generated inside the soy sauce bottle to flow through the auxiliary hole to the space between the lower cover 10 and the upper cover 20 to release internal pressure during storage or transportation of the soy sauce bottle, or after use when the sealing sheet 111 is re-embedded onto the lower cover 10. The auxiliary filter layer 1111 has the same structure and function as the filter layer 30. It can adsorb and filter the fermentation gases discharged through the auxiliary hole to a certain extent. The auxiliary filter layer 1111 can be a filter membrane, which can be fixed to the sealing sheet 111 during injection molding, or fixed to the sealing sheet 111 by bonding / welding, for example, by fixing the auxiliary filter layer 1111 with a welded pressure ring 1112.

[0040] Preferably, the diameter of the auxiliary hole can be 1-6 mm, and the diameter of the auxiliary filter layer 1111 is larger than the diameter of the auxiliary hole.

[0041] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
