TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of food packaging bottle, in particular to a leakage-proof device of a container bottle and the container bottle. BACKGROUND

[0002] Many viscous foods are stored in a container bottle, and consumers need to use a spoon to take the food, such as honey, chili sauce, etc. When the consumer scoops the food, the spoon inevitably contacts the bottle mouth of the container bottle, and the food is easily leaked out of the bottle mouth and onto the bottle body. Many consumers deliberately use the spoon to wipe the food adhered to the bottom of the spoon at the bottle mouth to avoid the food adhered to the bottom of the spoon from spilling out, and these foods are also easily leaked out of the bottle mouth and onto the bottle body, and finally solidify on the bottle body, which not only causes waste of food, but also affects the consumer's grip on the bottle body, causing a poor user experience for the consumer.

[0003] Therefore, the technical problem of food leakage onto the bottle body when the food is scooped by the spoon needs to be solved by those skilled in the art. CONTENT OF THE UTILITY MODEL

[0004] The present disclosure aims to overcome the deficiencies of the prior art and provide a leakage-proof device of a container bottle and the container bottle.

[0005] According to a first aspect of the present disclosure, a leakage-proof device of a container bottle is provided, which comprises:

[0006] a main body inserted into the container bottle and fixed with the bottle mouth, the main body being provided with an opening for communication between the inside of the container bottle and the outside, and being configured to take out the contents in the container bottle through the opening;

[0007] a liquid storage tank provided on the main body, the liquid storage tank being in communication with the inside of the container bottle through a liquid leakage port, and being configured to store the liquid leaked when the contents are taken out and flow back into the container bottle through the liquid leakage port.

[0008] In an embodiment of the present disclosure, the liquid storage tank is an annular liquid storage tank arranged around the opening.

[0009] In an embodiment of the present disclosure, the inner shell between the liquid storage tank and the opening is a thin-walled structure.

[0010] In an embodiment of the present disclosure, the outer shell of the liquid storage tank is a thin-walled structure, and the top of the outer shell of the liquid storage tank extends outwardly horizontally to form a fixing portion configured to be fixed with the bottle mouth.

[0011] In an embodiment of the present disclosure, the inner shell of the liquid storage tank between the liquid storage tank and the opening is higher than the outer shell of the liquid storage tank.

[0012] In one embodiment of the present disclosure, the inner shell of the liquid storage tank is 0.5-1.5 cm higher than the outer shell of the liquid storage tank.

[0013] In one embodiment of the present disclosure, the cross-sectional shape of the liquid storage tank is V-shaped.

[0014] In one embodiment of the present disclosure, the inner tank wall and the outer tank wall of the liquid storage tank have an inclination angle of 5-15° with respect to the vertical direction.

[0015] In one embodiment of the present disclosure, a plurality of liquid leakage openings are provided, and the plurality of liquid leakage openings are circumferentially and equally spaced on the bottom of the liquid storage tank.

[0016] According to a second aspect of the present disclosure, a container bottle is provided, which comprises a bottle body and a bottle mouth, and the anti-leakage device of the container bottle according to any one of the above embodiments.

[0036] The existing container bottle, when scooping food, the food will leak to the bottle body due to the contact between the spoon and the bottle mouth, not only causing the waste of food, but also causing the bad use experience of the consumer. Therefore, the present disclosure provides a leakage-proof device of a container bottle and a container bottle. In order to facilitate understanding, the specific structure and working principle of the leakage-proof device of the container bottle of the present disclosure and the container bottle will be described in detail below with reference to Figures 1-6 , in combination with the embodiments.

[0037] The leakage-proof device of the container bottle of the present disclosure comprises a main body, a liquid storage groove 2, wherein the main body is inserted into the container bottle and fixed with the bottle mouth, the main body is provided with an opening 1 for communicating the inside of the container bottle with the outside, and is configured to take out the contents in the container bottle through the opening 1; the liquid storage groove 2 is arranged on the main body, the liquid storage groove 2 is communicated with the inside of the container bottle through a liquid leakage port 3, and is configured to store the liquid leaked when taking out the contents, and flow back into the container bottle through the liquid leakage port 3.

[0038] Specifically, referring to Figure 1 , Figure 2 , the shape of the main body as a whole is annular, a circular opening 1 is arranged in the middle, the opening 1 communicates the inside of the bottle with the outside environment, and the size of the opening 1 can accommodate the spoon to enter and perform the scooping action, and the consumer uses the spoon to scoop the contents inside through the opening 1. In this embodiment, the contents refer to food, more specifically, some viscous or high oil content food, such as honey, chili sauce, garlic sauce, etc.

[0039] The main body is further provided with a liquid storage groove 2, and the bottom of the liquid storage groove 2 is provided with a liquid leakage port 3. When scooping food, the oil or food itself adhered to the spoon flows into the liquid storage groove 2, and flows back into the bottle through the liquid leakage port 3.

[0040] When scooping food traditionally, the consumer puts the whole spoon into the container bottle for scooping, and the oil or food itself adhered to the bottom of the spoon, when the spoon is taken out, the spoon contacts the edge of the bottle mouth, which destroys the liquid tension of the spoon bottom, so that the liquid adhered to the spoon bottom flows back along the edge of the bottle mouth, part of the liquid flows back into the bottle, and the other part of the liquid flows out to the bottle body, causing the bad use experience of the consumer.

[0041] Further, referring to Figure 3 , in the actual application of the leakage-proof device of the container bottle of the present disclosure, the consumer puts the whole spoon into the container bottle through the opening 1 on the main body for scooping, and the oil or food itself adhered to the bottom of the spoon, when the spoon is taken out, the spoon will first contact the main body part between the opening 1 and the liquid storage groove 2, and then make the liquid adhered to the spoon bottom flow back along the shell, part of the liquid flows back into the bottle, and the other part of the liquid flows into the liquid storage groove 2, and flows back into the bottle through the liquid leakage port 3, which not only reduces the waste of food, but also avoids the liquid flowing out to dirty the bottle body, and improves the use experience of the consumer.

[0042] In one embodiment, the liquid storage tank 2 is an annular liquid storage tank arranged around the opening 1.

[0043] Specifically, referring to Figure 1 , Figure 3 , in this embodiment, the shape of the liquid storage tank 2 is annular, and it is arranged on the main body around the opening 1. In this way, no matter from which direction the consumer takes out the spoon, it will contact the shell between the opening 1 and the liquid storage tank 2, so that the liquid attached to the spoon flows to the liquid storage tank 2 and then flows back into the bottle, without guiding the consumer's usage habits, improving the consumer's usage experience.

[0044] In another embodiment, referring to Figure 5 , the shape of the liquid storage tank 2 is only arc-shaped, and the center of the arc corresponds to the center of the opening 1. The shells on both sides of the liquid storage tank 2 are provided with protruding indication arrows, which point to the liquid storage tank 2, indicating the consumer to wipe off the liquid attached to the spoon on the shell between the opening 1 and the liquid storage tank 2, so that the liquid flows to the liquid storage tank 2 and then flows back into the bottle.

[0045] In one embodiment, the inner shell 22 between the liquid storage tank 2 and the opening 1 is a thin-walled structure.

[0046] Specifically, referring to Figure 1 , during the contact between the inner shell 22 between the liquid storage tank 2 and the opening 1 and the spoon, the liquid attached to the bottom of the spoon will flow onto the inner shell 22, and the surface tension of the liquid will cause it to stay on the inner shell 22 and not flow into the liquid storage tank 2. Therefore, the inner shell 22 between the liquid storage tank 2 and the opening 1 is designed as a thin-walled structure, which destroys the surface tension of the liquid, so that the liquid cannot stay on the inner shell 22 and can only flow back into the bottle along the inner wall of the opening 1 or to the liquid storage tank 2 along the inner groove wall of the liquid storage tank 2. In this way, the liquid is prevented from staying on the inner shell 22 and then causing solidification waste.

[0047] In one embodiment, the outer shell 23 of the liquid storage tank 2 is a thin-walled structure, and the top of the outer shell 23 of the liquid storage tank 2 extends outwardly to form a fixing portion 21, which is configured to be fixed with the bottle mouth.

[0048] Specifically, since the area of the bottle mouth itself is relatively small, the area of the opening 1 also needs to consider the insertion of the spoon for scooping, therefore, the outer shell 23 of the liquid storage tank 2 adopts a thin-walled structure, and the inner shell 22 between the liquid storage tank 2 and the opening 1 also adopts a thin-walled structure, in the limited area of the bottle mouth, the area of the slot of the liquid storage tank 2 is as large as possible, which can facilitate the liquid storage tank 2 to catch the spilled liquid when the spoon is taken.

[0049] Further, referring to Figure 3, considering that in practical application, the consumer scoops a full spoon of sauce, a slight twist of the wrist causes the liquid in the spoon to spill out, the larger the slot area of the liquid storage tank 2, the more opportunities there are for the liquid to fall into the liquid storage tank 2, and then flow back into the bottle through the liquid leakage port 3.

[0050] In detail, with reference to Figure 1 、 Figure 4 The top of the outer shell 23 of the liquid storage tank 2 extends horizontally outward to form a fixing portion 21, in this embodiment, the fixing portion 21 is also annular in shape, is adapted to the bottle mouth, and the outer diameter of the fixing portion 21 is equal to the outer diameter of the bottle mouth. In this way, the fixing portion 21 is lapped on the bottle mouth to achieve fixation, and the liquid storage tank 2 and the liquid leakage port 3 are both located in the bottle mouth, so that the liquid in the liquid storage tank 2 flows back into the bottle through the liquid leakage port 3.

[0051] In another embodiment, the fixing portion 21 is arc-shaped as a whole, the center of the arc is located at the center of the bottle mouth, and the top of the outer shell 23 of the liquid storage tank 2 extends horizontally outward in the circumferential direction to form a plurality of fixing portions 21. Taking four fixing portions 21 as an example, the four fixing portions 21 are arranged at equal intervals on the outer shell 23 of the liquid storage tank 2, and the included angle between the axes corresponding to adjacent fixing portions 21 is 90°.

[0052] In one embodiment, the inner shell 22 between the liquid storage tank 2 and the opening 1 is higher than the outer shell 23 of the liquid storage tank 2.

[0053] Specifically, the inner shell 22 between the liquid storage tank 2 and the opening 1 is designed to be higher than the outer shell 23 of the liquid storage tank 2. In this way, visual guidance is given to the consumer, so that when the consumer wipes off the liquid adhered to the spoon bottom, the spoon bottom is in contact with the inner shell 22 between the liquid storage tank 2 and the opening 1, or in contact with the inner wall of the opening 1, so that the liquid flows back into the bottle or flows into the liquid storage tank 2.

[0054] In detail, in another embodiment, if the inner shell 22 between the liquid storage tank 2 and the opening 1 is flush with the outer shell 23 of the liquid storage tank 2, the consumer does not know where to wipe off the liquid adhered to the spoon bottom. Even, after seeing the liquid storage tank 2, the consumer will be more inclined to wipe off the liquid adhered to the spoon bottom on the outer shell 23 of the liquid storage tank 2. Such operation will still cause the liquid to flow out of the bottle body. Therefore, a prompt needs to be provided in the liquid storage tank 2 or on the main body to guide the consumer to wipe off the liquid adhered to the spoon bottom on the inner shell 22 between the liquid storage tank 2 and the opening 1.

[0055] Therefore, the inner shell 22 between the liquid storage tank 2 and the opening 1 is set to be higher than the outer shell 23 of the liquid storage tank 2, so that the consumer can complete the use only by habit and subconsciously without the need to learn according to the instructions, thereby improving the user experience of the consumer.

[0056] In addition, since the container bottle of the present disclosure mainly contains some viscous or high oil content food such as honey, chili sauce, garlic sauce and the like, the liquid will flow down along the inner groove wall of the liquid storage groove 2 without splashing and other problems, and will not splash out of the liquid storage groove 2 due to the low height of the outer shell 23 of the liquid storage groove 2.

[0057] In one embodiment, the height of the inner shell 22 between the liquid storage groove 2 and the opening 1 is 0.5-1.5 cm higher than the height of the outer shell 23 of the liquid storage groove 2.

[0058] Specifically, after use, the bottle cap is convenient to cover, and the leakage prevention device of the container bottle of the present disclosure does not need to be taken out. Preferably, the height of the inner shell 22 between the liquid storage groove 2 and the opening 1 is 0.5-1.5 cm higher than the height of the outer shell 23 of the liquid storage groove 2, and specifically 1 cm.

[0059] In one embodiment, the cross-sectional shape of the liquid storage groove 2 is V-shaped.

[0060] Specifically, the inner groove wall of the liquid storage groove 2 is inclined inward relative to the vertical direction, and the outer groove wall of the liquid storage groove 2 is inclined outward relative to the vertical direction, forming a liquid storage groove 2 with a V-shaped cross section. By such arrangement, on the one hand, the slot area of the liquid storage groove 2 is increased, which can facilitate the liquid spilled during scooping to be caught by the liquid storage groove 2. On the other hand, the groove bottom is not horizontal structure, but has an included angle, so that the liquid is difficult to stay in the liquid storage groove 2 and flows back into the bottle as much as possible from the liquid leakage port 3. Compared with the horizontal groove bottom, the setting of the included angle makes the liquid not easy to accumulate, but flows along the center line between the two side walls, and then is discharged from the liquid leakage port 3.

[0061] In one embodiment, the inclination angle of the inner groove wall and the outer groove wall of the liquid storage groove 2 relative to the vertical direction is 5°-15°.

[0062] Specifically, the liquid discharge efficiency of the V-shaped groove bottom is related to the included angle of the inner groove wall of the liquid storage groove 2 and the outer groove wall of the liquid storage groove 2, and the liquid discharge efficiency mainly depends on the comprehensive effect of the included angle on the liquid convergence ability and flow resistance.

[0063] Further, if the included angle is a right angle, i.e. a rectangular groove bottom, it is easy to form a groove bottom water accumulation area. When the liquid flows into the liquid storage groove 2 along the inner groove wall of the liquid storage groove 2 and flows through the right angle, the flow direction of the liquid changes suddenly, forming a low pressure vortex area, the flow velocity of the liquid decreases, and only relies on the inertial flow, and the liquid stays in the corner stably due to the surface tension and capillary action.

[0064] If the included angle is an obtuse angle, the obtuse angle groove bottom tends to be flat, the tendency of the liquid to converge to the center is weakened, the low flow velocity area is expanded, and the liquid is easy to deposit on the groove bottom of the liquid storage groove 2.

[0065] If the included angle is an acute angle, the inner groove wall of the liquid storage tank 2 and the outer groove wall of the liquid storage tank 2 have large inclination, the gravity force along the groove bottom direction of the liquid storage tank 2 is stronger, the driving liquid quickly converges to the lowest point of the groove bottom of the liquid storage tank 2, and a concentrated flow channel is formed. The flow path of the liquid is concentrated, the acute angle structure forces the liquid to flow along the two side walls to the center line, reduces the horizontal diffusion, and avoids the liquid retention at the edge. The surface tension of the liquid is difficult to stably maintain the liquid film at the sharp included angle, and the liquid is more easily separated from the groove bottom of the liquid storage tank 2.

[0066] In summary, the included angle between the inner groove wall and the outer groove wall of the liquid storage tank 2 is an acute angle, and the inclination angle of the inner groove wall and the outer groove wall of the liquid storage tank 2 relative to the vertical direction is 5°-15°, which can form an included angle of 10°-30°, so that the liquid flow rate is fast, the flow path is concentrated, and the liquid is more easily separated from the groove bottom of the liquid storage tank 2, and then flows back into the bottle through the liquid leakage port 3.

[0067] In one embodiment, the liquid leakage port 3 is provided with a plurality of liquid leakage ports 3, and the plurality of liquid leakage ports 3 are arranged at the bottom of the liquid storage tank 2 in a circumferential direction.

[0068] Specifically, the area and number of the liquid leakage port 3 determine the efficiency of the liquid in the liquid storage tank 2 flowing back into the bottle, referring to Figure 1 In the embodiment, the shape of the liquid leakage port 3 is an arc shape matched with the groove bottom of the liquid storage tank 2, and the cross-sectional shape of the liquid leakage port 3 is also V-shaped. The liquid flowing from the inner groove wall of the liquid storage tank 2 above the liquid leakage port 3 can directly flow back into the bottle through the liquid leakage port 3, and the liquid on both sides of the liquid leakage port 3 flows along the groove bottom of the liquid storage tank 2 to the liquid leakage port 3 and then flows back into the bottle. The number of the liquid leakage port 3 is 4, and the 4 liquid leakage ports 3 are arranged at the groove bottom of the liquid storage tank 2 in a circumferential direction, and the included angle between the axes corresponding to the adjacent liquid leakage ports 3 is 90°.

[0069] In another embodiment, referring to Figure 6 In order to improve the efficiency of the liquid in the liquid storage tank 2 flowing back into the bottle, the number of the liquid leakage port 3 can be increased or the area of the liquid leakage port 3 can be increased, such as arranging 8 liquid leakage ports 3 in a circumferential direction or arranging the central angle of the liquid leakage port 3 to be 160°, and relatively arranging two liquid leakage ports 3. Most of the liquid does not need to reach the groove bottom of the liquid storage tank 2, but directly flows back into the bottle through the liquid leakage port 3, thereby reducing the retention of the liquid in the liquid storage tank 2.

[0070] The container bottle of the present disclosure includes a bottle body and a bottle mouth, and the liquid leakage prevention device of the container bottle of any one of the above embodiments.

[0071] Specifically, referring to Figure 1 , Figure 4In the embodiment, the outer diameter of the bottle mouth of the container bottle is equal to the diameter of the main body, the edge of the main body has a fixing portion 21, the fixing portion 21 is lapped on the bottle mouth to be fixed, and the thread inside the bottle cap is arranged below, and the inner shell body 22 between the liquid storage groove 2 and the opening 1 is reserved above the outer shell body 23 of the liquid storage groove 2. In this way, even if the leakage-proof device of the container bottle is put in, the bottle cap can still be tightly screwed and sealed, and after the consumer uses it, the bottle cap can be tightly screwed for storage, without taking out the leakage-proof device of the container bottle, thereby improving the use experience of the consumer.

[0072] In addition, the container bottle of the present disclosure is inserted into the leakage-proof device of the container bottle, the consumer puts the whole spoon into the container bottle through the opening 1 on the body to dig, the spoon bottom will adhere to the oil liquid or the food itself, when the spoon is taken out, the spoon will first contact the inner shell body 22 between the liquid storage groove 2 and the opening 1, and then the liquid adhered to the spoon bottom flows back along the shell body, part of the liquid flows back into the bottle, and the other part of the liquid flows into the liquid storage groove 2 and flows back into the bottle through the liquid leakage port 3, which not only reduces the waste of food, but also avoids the liquid from flowing out and staining the bottle body, thereby improving the use experience of the consumer.

[0073] In another embodiment, the outer diameter of the bottle mouth of the container bottle is smaller than the diameter of the main body, because the outer groove wall of the liquid storage groove 2 is outwardly inclined, the main body of the leakage-proof device of the container bottle can be clamped at the bottle mouth, and after the consumer uses it, the leakage-proof device of the container bottle is taken out for next use.

[0074] In addition, in order to facilitate better understanding, the leakage-proof device of the container bottle and the use process of the container bottle will be described in detail below in combination with the actual application scene of the leakage-proof device of the container bottle and the container bottle.

[0075] 1. Open the bottle cap of the container bottle, insert the leakage-proof device of the container bottle into the bottle mouth of the container bottle, and lap the fixing portion 21 on the bottle mouth to be fixed;

[0076] 2. Use the spoon to dig the food, and wipe off the liquid adhered to the spoon bottom on the thin-walled shell body between the liquid storage groove 2 and the opening 1;

[0077] 3. The liquid flows along the inner groove wall of the liquid storage groove 2 to the liquid leakage port 3, and then flows back into the bottle;

[0078] 4. After use, directly screw the bottle cap, and wait for next use.

[0079] Having described above several embodiments of the disclosure, any modifications and variations that fall within the scope of the described embodiments are also contemplated by the inventor(s). As such, the foregoing description is not intended to limit the scope of the disclosure, and it is recognized that modifications are contemplated which can provide one or more benefits and which are within the scope of the disclosure.
