Description

Technical Field

[0001] This invention relates to the field of containers and related components, specifically to a blowout preventer assembly and a blowout preventer container using the same. Background Technology

[0002] Liquids undergo strong vaporization at high temperatures. This is a purely physical change, and the liquid's chemical properties remain unchanged. In everyday life, common containers such as water cups and baby bottles, especially those with straws, can sometimes experience increased internal pressure due to the high-temperature vaporization of the liquid inside. This can lead to hot liquid splashing along the straw, which is extremely dangerous.

[0003] Currently, the solution to this problem is to install an inner lid between the cup lid and the cup body. The inner lid has an exhaust pipe. The purpose of the exhaust pipe is to allow the gas inside the cup to be released under pressure when there is high temperature gas inside the cup body, thereby relieving pressure and preventing splashing.

[0004] However, traditional exhaust pipes only focus on the design of venting from the outside of the container to the inside, and add anti-spray plugs to the water intake channel of the container, which is actually blocking the high-pressure gas inside the container. For example, the anti-spray structure of a cup lid with application number "CN202121300081.9" (the return valve is a hollow rotating body structure that is connected vertically); the anti-spray water intake nozzle with application number "CN202022326988.4" provides a groove (equivalent to the groove in this case) and an anti-suction pressure balance valve on the anti-spray component; the anti-spray liquid nipple for baby bottles with application number "CN204261061U" uses a return valve 2 to lock in the inner cavity at the lower end of the nipple head 1. The core point is that when hot water or hot milk generates high-pressure gas in the bottle, the overall idea is to set a one-way return valve (similar to the anti-suction pressure balance valve in "CN202022326988.4"), and the water outlet channel is set with a retractable pleated neck to achieve the purpose of anti-spray.

[0005] However, the aforementioned patents primarily focus on the venting channels of the bottles / cups, using a one-way valve design to ensure smooth airflow into the bottle during sucking and prevent choking. They also disclose anti-spray (high-temperature) devices on the suction channels. However, due to their prominent structure, large opening movement during each venting operation, and poor fatigue resistance, these separate technologies are prone to damage. Furthermore, the numerous manufacturing components and complex structure often result in failure to achieve the desired effect after a period of use, sometimes even leading to leakage. In particular, they fail to provide a fundamental anti-spray function, causing hot water splashes and affecting normal use. Summary of the Invention

[0006] In view of this, it is necessary to provide a blowout preventer component and a blowout preventer container that address the problems of traditional exhaust pipe and blowout preventer separation technology, which is prone to damage due to its prominent structure, large opening movement during each exhaust, poor fatigue resistance, numerous production parts, complex structure, and in daily cleaning and use, often fails to achieve the expected blowout preventer effect after a period of use, or even leaks, affecting normal use.

[0007] The technical solution of this invention is as follows:

[0008] In a first aspect, the present invention provides a blowout preventer assembly, including an inner cover, an venting pad at the bottom of the inner cover, and a protrusion extending from the top of the venting pad. The protrusion engages with the inner cover through a notch at the bottom of the inner cover. At least one protrusion is provided, and the number of notches is greater than the number of protrusions. The protrusions are positioned corresponding to the notches. A limiting tube is provided at the bottom of the venting pad, and a first peak, a trough, and a second peak are sequentially provided on the outer side of the limiting tube. At least one first opening is provided at the bottom of the trough, and no more than three second openings are provided at the top of the first peak.

[0009] Furthermore, a cavity is formed between the inner cover and the venting pad.

[0010] Furthermore, the thickness of the first and second peaks is 0.4–1.5 mm, and the radius of curvature of the peaks is 1.5–2.04 mm.

[0011] Preferably, the thickness of the first peak is 0.6 mm and the radius of curvature is 2.04 mm; the thickness of the second peak is 0.6 mm and the radius of curvature is 1.5 mm.

[0012] Furthermore, the trough thickness is 0.6 mm and the radius of curvature is 1.55 mm.

[0013] Furthermore, the size of the first opening is larger than that of the second opening.

[0014] Preferably, there are three first openings, which are evenly distributed along the circumference of the trough.

[0015] Preferably, there is one second opening.

[0016] Preferably, the venting pad has an absorption ring inside.

[0017] Preferably, an installation ring is fixedly connected to the outer wall of the absorption ring.

[0018] Preferably, the outer wall of the mounting ring is engaged with the inner wall of the venting pad via an annular groove.

[0019] Preferably, the outer wall of the mounting ring has an arc-shaped surface on the top and a sloped surface on the bottom.

[0020] Optionally, a handle is provided at the top of the mounting ring.

[0021] Preferably, the handle and the mounting ring are integrally formed.

[0022] Furthermore, the venting pad is made of silicone material with a temperature of 30 to 50 degrees, preferably silicone material with a temperature of 40 degrees.

[0023] Secondly, the present invention provides a blowout preventer container using the above-mentioned blowout preventer components, including a container body, a container cap threadedly connected to the top of the container body, a straw installed on the inner wall of the container cap, the outer wall of the straw passing through the container cap, the inner cap and the limiting tube from top to bottom, and the outer wall of the straw being tightly fitted with the inner wall of the limiting tube.

[0024] Beneficial effects

[0025] This invention provides a blowout preventer assembly and a blowout preventer container using the same, which has the following advantages compared to conventional technologies:

[0026] This anti-spray component, through the cooperation of the protrusions, notches, crests and the second opening, can effectively release the high-pressure, high-temperature hot air inside the container, preventing hot air from being sprayed out from the nipple, cup head and sippy tube head.

[0027] By coordinating the protrusions, notches, troughs, and the first opening, multiple openings can be opened and closed simultaneously, resulting in a small single opening and closing action. This effectively clears the air passages inside and outside the bottle / cup. If this component is used in a baby bottle, it can prevent the nipple / sippy spout from getting stuck due to poor airflow, thus preventing the baby from drinking. It also avoids damage caused by material fatigue, ensuring the expected working effect, greatly improving the service life, and preventing leakage, splashing, and other phenomena.

[0028] The combination of the protrusion and the notch not only allows for the provision of vent holes, but also serves to limit the inner cover and the venting pad, ensuring a tight connection between the two.

[0029] By forming a cavity, mounting ring, and annular groove between the inner cover and the venting pad, partially liquefied gas can be collected, preventing overflow. At the same time, it reduces bacterial growth inside the inner cover and venting pad, making it easy to remove and install, and providing convenience for cleaning and disinfection.

Detailed Implementation

[0038] This invention provides the following technical solutions:

[0039] Please see Figure 1 , Figure 2 and Figure 3 A blowout preventer includes an inner cover 1, an venting pad 2 at the bottom of the inner cover 1, and a protrusion 3 extending outward from the top of the venting pad 2. The protrusion 3 fits into the inner cover 1 through a notch 4 at the bottom of the inner cover 1. At least one protrusion 3 is provided, and the number of notches 4 is greater than the number of protrusions 3. The positions of the protrusions 3 correspond to the notches 4. A limiting tube 9 is provided at the bottom of the venting pad 2. A first crest 5, a trough 6, and a second crest 7 are sequentially provided on the outer side of the limiting tube 9. At least one first opening 8 is provided at the bottom of the trough 6, and no more than three second openings 19 are provided at the top of the first crest 5. The size of the first opening 8 is larger than that of the second opening 19. Preferably, there are three first openings 8, evenly distributed along the circumference of the trough 6. There is one second opening 19. The preferred limitation of the size of the first opening being larger than that of the second opening and the number of openings allows the internal and external gas channels of the water container to be in an optimal balance.

[0040] In the specific implementation process, it is worth noting that the inner lid 1 is one of the essential sealing components for water cups, baby bottles, etc. It is generally directly fixed inside the cup lid and in contact with the cup body to seal the cup body. The outer edge of the inner lid 1 is provided with a protrusion that can be locked at the opening of the cup body. This is a well-known technology to those skilled in the art and will not be described in detail here. The technical solution of this application mainly uses a protrusion 3 and a notch 4 at the connection between the venting pad 2 and the inner lid 1 to limit the venting pad 2 and the inner lid 1. The number of notches 4 is greater than the number of protrusions 3. In addition to the protrusions 3 and notches 4 that fit together, the extra notches 4 can be used for venting. At the same time, the current cup lid is generally connected to the cup body by a thread. It is difficult to achieve a complete seal by simply using a threaded connection. Therefore, the notch 4 can serve as a channel for the cup body to communicate with the outside atmosphere. The gas inside the cup body can be discharged to the outside through the extra notches 4, which plays a role in depressurization and prevents the high-temperature liquid inside the bottle from spraying out from the straw under pressure. Furthermore, when the liquid is drawn in, the first peak 5 is deformed by atmospheric pressure, and the external gas can smoothly compress the first opening 8 to open (set on the trough 6). The gas passes through the excess notch 4, and a cavity is formed between the inner cover 1 and the venting pad 2. Then, the gas passes through the first opening 8 and the venting pad 2 to enter the interior of the container.

[0041] Under the action of high-temperature gas inside the cup, the first wave peak 5 deforms, causing the second opening 19 of the first wave peak 5 to open, so that the high-temperature and high-pressure gas inside the cup can pass through the second opening 19 and through the cavity formed between the inner cover and the exhaust pad, and finally be discharged to the outside through the notch 4.

[0042] Unlike traditionally disclosed technologies that separate the exhaust pipe and the anti-splash device, this technical solution integrates the exhaust, leak prevention, and anti-splash device into one unit. At the same time, a gas exchange, leak prevention, and anti-splash space is constructed between the inner cover 1 and the exhaust pad 2. Multiple first openings 8 are provided on the troughs 6, first peaks 5, and second peaks 7 of the exhaust pad 2, and one second opening 19 is provided. Therefore, the opening and closing action of a single second opening 19 is small, which is very convenient for gas exchange between the inside and outside of the bottle, preventing suction and high-pressure splashing. At the same time, the one-piece molding technology is very convenient for mass production and is not easily damaged due to material fatigue.

[0043] Furthermore, the thickness of the first and second peaks is 0.4–1.5 mm, and the radius of curvature of the peaks is 1.5–2.04 mm. Preferably, the thickness of the first peak is 0.6 mm, and the radius of curvature is 2.04 mm; the thickness of the second peak is 0.6 mm, and the radius of curvature is 1.5 mm. The thickness of the trough is 0.6 mm, and the radius of curvature is 1.55 mm.

[0044] In the specific implementation process, it is worth noting that the cavity setting can provide more overflow space for high-temperature gas, avoid the high-temperature gas from accumulating between the exhaust pad 2 and the notch 4, which makes it difficult to discharge and form high pressure, and provide more time for the notch 4 to release pressure through the threaded connection between the cup lid and the cup body.

[0045] Specifically, when using this anti-spray assembly, the top of the inner cover 1 should first be adjusted to fit the outer cup lid without altering the technical solution described in this application. Under this premise, the inner cover 1 and the outer cup lid are fixed in place. Simultaneously, the venting pad 2 is placed against the opening of the cup body via its outer wall protrusion. At this point, the cup lid and cup body can be threaded together. During this process, ensure that the protrusion 3 on the top of the venting pad 2 aligns with the notch 4 at the bottom of the inner cover 1 to achieve positioning. The excess notch 4 can serve as a channel for communication between the cup body and the outside atmosphere. A straw of suitable size is inserted into the limiting tube 9, and the two are sealed. Under the action of the high temperature gas inside the cup, the trough 6 deforms, which causes the second opening 19 of the first peak 5 to open. This allows the gas inside the cup to be discharged from the second opening 19 and the notch 4 to the cavity between the inner cover 1 and the venting pad 2, and then discharged to the outside through the notch 4 that does not cooperate with the protrusion 3, thus avoiding splashing. At the same time, when the straw is used to suck up the liquid inside the cup, the first opening 8 also opens under the action of atmospheric pressure (suction), ensuring that the liquid flows out smoothly from the straw.

[0046] It is understood that in this embodiment, the inner cover 1 and the venting pad 2 can be integrated as a single unit, such as... Figure 5 As shown, this makes installation and use more convenient and quick; and / or, the limiting tube 9 can extend to the bottom of the inner cover 1, so that when combined with the bottle cap with the spout, a one-sip suction structure can be formed.

[0047] Meanwhile, the second peak 7 and the first peak 5 can be located on the same circumference and alternately set, with the two sandwiched to form a trough 6. This is only a part of the implementation of this embodiment, not all of the embodiments. Without departing from the concept of the present invention, several modifications and improvements can be made, all of which fall within the protection scope of the present invention.

[0048] In one feasible approach, please refer to Figure 1 , Figure 2 and Figure 4 An absorption ring 11 is provided inside the exhaust pad 2.

[0049] In the specific implementation process, it is worth noting that the absorption ring 11 can be made of food-grade sponge. The purpose is that a small part of the high-temperature gas inevitably liquefies between the inner cover 1 and the exhaust pad 2, which can be absorbed by the absorption ring 11 to prevent it from overflowing out through the opening 4.

[0050] Furthermore, an installation ring 10 is fixedly connected to the outer wall of the absorption ring 11.

[0051] In the specific implementation process, it is worth noting that the purpose of the mounting ring 10 is to support the absorption ring 11, so as to limit the position of the absorption ring 11 and the exhaust pad 2.

[0052] Furthermore, the outer wall of the mounting ring 10 is engaged with the inner wall of the venting pad 2 via the annular groove 13.

[0053] In the specific implementation process, it is worth noting that the absorption ring 11 and the exhaust pad 2 are fixed by the cooperation of the annular groove 13 and the mounting ring 10.

[0054] Furthermore, an arc-shaped surface 14 is provided on the upper part of the outer wall of the mounting ring 10, and a slope 15 is provided on the bottom part of the outer wall of the mounting ring 10 to facilitate the dissipation of steam bubbles on the arc-shaped surface and the slope.

[0055] In the specific implementation process, it is worth noting that the arc-shaped surface 14 is designed to facilitate the removal of the mounting ring 10 from the annular groove 13 inside the inner wall of the exhaust pad 2. Similarly, the slope 15 is designed to facilitate the insertion of the mounting ring 10 into the interior of the exhaust pad 2.

[0056] Furthermore, a handle 12 is provided on the top of the mounting ring 10.

[0057] In the specific implementation process, it is worth noting that the handle 12 makes it convenient for users to pull the installation ring 10.

[0058] Furthermore, the handle 12 and the mounting ring 10 are integrally formed.

[0059] In the specific implementation process, it is worth noting that the purpose of this design is to ensure the firmness between the handle 12 and the mounting ring 10.

[0060] Specifically, based on the above embodiments, a small portion of the high-temperature gas inevitably liquefies between the inner cover 1 and the exhaust pad 2. This liquefaction can be absorbed by the absorption ring 11 to prevent overflow from the notch 4. When cleaning the cup, the mounting ring 10 can be removed from the annular groove 13 on the inner wall of the exhaust pad 2 using the handle 12. After that, the mounting ring 10 and the absorption ring 11 are cleaned. The cleaned absorption ring 11 and the mounting ring 10 can then be reinstalled in the annular groove 13 on the inner wall of the exhaust pad 2 for future use.

[0061] Furthermore, in this invention, the venting pad is made of silicone material with a temperature range of 30 to 50 degrees Celsius, preferably 40 degrees Celsius silicone material, which has better high temperature resistance, softness, and electrical resistance, making it suitable for use in food containers.

[0062] The present invention also provides a blowout preventer container using the above-mentioned blowout preventer components, including but not limited to containers such as water cups, baby bottles, and water bottles.

[0063] See Figure 6 and Figure 7 This invention provides a structure for a spray-proof baby bottle, including a container body 16, a container cap 17 threadedly connected to the top of the container body 16, a straw 18 installed on the inner wall of the container cap 17, and the outer wall of the straw 18 passing through the container cap 17, the inner cap 1, and the limiting tube 9 from top to bottom, with the outer wall of the straw 18 tightly fitting the inner wall of the limiting tube 9. This invention conducted a series of spray-proof experiments comparing this spray-proof baby bottle (including both separate inner cap and venting pad and integrated designs) with existing commercially available brand baby bottles. The specific test method was as follows: hot water at different temperature ranges was filled into various bottles, with a water volume of 200mL. After standing for 5 minutes, the bottles were vigorously shaken for 20 seconds, and the spraying of water was observed during the standing process and after vigorous shaking. The results are shown in Table 1.

[0064] Table 1. Results of the Spray Prevent Test

[0065]

[0066]

[0067] Table 1 shows that the baby bottle using the split anti-spray component of this invention does not spray water when filled with hot water at 90-100℃ and left to stand; traditional anti-spray cups can only prevent spraying water when left to stand in water at 70-80℃ or lower. Furthermore, when the cup is vigorously shaken, the baby bottle using the anti-spray component of this invention can prevent spraying water at a water temperature of 80-90℃; traditional anti-spray cups can only prevent spraying water when vigorously shaken in water at a water temperature of 60-70℃ or lower.

[0068] A comparison of a traditional one-sip water cup with a single-sip design and a one-sip water cup with the new anti-splash component:

[0069] 1. Anti-spray component: The one-sip water cup does not spray water when filled with 90-100℃ hot water and left to stand, while traditional one-sip water cups will spray water when left to stand with water at 60-70℃.

[0070] 2. Shake the anti-spray component of the one-sip water cup vigorously. It will not spray water at 80-90℃. Traditional one-sip water cups will not spray water at a water temperature of 50-60℃.

[0071] Furthermore, in the specific implementation process, it is worth noting that the container lid 17 and the container body 16 are only one installation method of the inner lid 1 and the venting pad 2, including but not limited to this. The attached drawings are only schematic diagrams and do not impose structural limitations on the container lid 17, the container body 16 and the straw 18. Several modifications and improvements can still be made. For example, the container body 16 and the container lid 17 can be matching free-sucking anti-spray baby bottles, free-sucking anti-spray sippy cups and sippy cups, etc., in which the straw 18 and the limiting tube 9 should be sealed.

[0072] It is understandable that the container body 16 and the container lid 17 can also be connected by snap-fit, socket, or other similar means.

[0073] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
