Description

Technical Field

[0001] The invention relates to the field of daily chemical product containers, and more specifically, to a quantitative cover for a container for solid particles. Background Art

[0002] When solid products in daily household chemicals are packaged in packaging bags or shaped containers, when quantitative sampling is required, users are usually required to pour the solid products into the lid and keep them flush, and then pour them out through the lid. In this way, users must use both hands to achieve the effect of quantitative sampling. When there is not much solid product left in the packaging bag or shaped container, users need to tilt it at a large angle to pour out the product, which also makes it difficult to control the force at a large tilt angle, resulting in difficulty in controlling the amount of product poured out.

[0003] How to design a quantitative cap so that the user can pour out a quantitative product effortlessly and stably without using both hands to operate at the same time is an urgent problem to be solved in the art. Summary of the invention

[0004] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provide a quantitative cover for a container for solid particles, which is used to solve the problem that the pouring of the product depends on the joint operation of both hands, the user has difficulty in controlling the force when pouring the product, and the pouring amount of the product is difficult to maintain a stable quantitative amount.

[0005] The technical solution adopted by the present invention is to provide a quantitative cover for a container for solid particles, which is a cover body arranged on the container, wherein the cover body includes a main cover for pre-storage and discharge and an outward expansion connection seat for quantitative discharge, the main cover is provided with a longitudinal partition and is divided into a second space and a fourth space, the outward expansion connection seat is provided with an inclined partition and is divided into a first space and a third space, the bottom of the first space is provided with a buffer port connected to the container, and the top is connected to the bottom of the second space; the inclined partition is inclined from the third space to the first space, and forms a pre-storage port with the side wall at the bottom of the second space; the top of the second space is closed, and the bottom is provided with a blocking port connected to the top of the third space; the bottom of the third space is closed, and the top is connected to the bottom of the fourth space, and the top of the fourth space is provided with a discharge port.

[0006] It is beneficial that when the container is poured with one hand, the solid particles in the container are pre-stored in the second space on the main cover, and a quantitative amount of solid particles are intercepted in the third space formed by the outward expansion connecting seat, so as to achieve the effect of quantitative material extraction at the discharge port; the buffering of the solid particles when entering the main cover is achieved through the buffer port, so that when the tilt angle of the container is less than 45°, the solid particles are blocked in the first space and cannot enter the second space, so as to avoid the solid particles directly overflowing from the discharge port when the tilt angle of the container is not enough; the solid particles are intercepted through the blocking port between the inclined partition and the longitudinal partition, and when the tilt angle of the container is greater than 45°, the solid particles enter the third space stably through the first space and the second space in turn and achieve quantitative interception; the discharge of the solid particles is achieved through the discharge port, so that the solid particles intercepted in the third space are all poured out.

[0007] Furthermore, the overlapping distance between the longitudinal partition and the inclined partition in the vertical direction is b, and the gap distance between the pre-storage port and the buffer port in the horizontal direction is a, and b≥a.

[0008] It is beneficial to limit the flow path and flow speed of solid particles by setting the overlapping distance b, so as to prevent the solid particles from entering the third space directly from the first space without passing through the second space; by setting the gap distance a, when the inclination angle of the container is less than 45°, the solid particles are blocked in the first space and will not enter the second space; through the numerical relationship between b and a, the solid particles are blocked when the inclination angle of the container is not enough, and the quantitative interception effect in the third space is achieved when the inclination angle is sufficient.

[0009] Furthermore, the main cover also includes a side wall, a top wall and a curved wall connected between the side wall and the longitudinal partition, the top wall is used for the top closure of the second space, and the curved wall is used for discharging from the discharge port of the fourth space; the outward expansion connecting seat also includes a surrounding wall extending from the side wall into the container, a bottom wall and a buffer partition connected to the surrounding wall, the bottom wall is used for the bottom closure of the third space, and the buffer partition is inclined upward or downward from the surrounding wall and is used for buffering the buffer port of the first space.

[0010] It is beneficial to form a space protruding above the container through the side wall, and a second space with an opening facing downward and a fourth space with openings at the top and bottom are divided in the space formed by the side wall through the top wall and the longitudinal partition, and the opening of the fourth space is limited to a discharge port with a gradually decreasing diameter through the curved wall, so that solid particles can be poured out smoothly and quickly during the discharge process; it is beneficial to form a space that is connected to the bottom of the main cover and the top of the container at the same time through the surrounding wall, and a third space with an opening facing upward and a first space with openings at the top and bottom are divided in the space formed by the surrounding wall through the bottom wall and the inclined partition.

[0011] Furthermore, the angle between the inclined partition and the side wall is A1, 15°<A1<45°, and the angle between the buffer partition and the side wall is A2, 105°<A2<135.

[0012] It is beneficial to form a specific shape of the third space by tilting the specific angle between the partition and the side wall, thereby controlling the volume capacity according to the diameter of the solid particles. By buffering the specific angle between the partition and the side wall, a specific shape of the first space is formed, thereby achieving a blocking effect on solid particles when the tilt angle of the container is not enough.

[0013] Furthermore, the buffer partition includes a first edge and a second edge, the first edge is an arc-shaped edge connected to the lower edge of the surrounding wall, and the second edge is a straight edge or a curved edge of the buffer port.

[0014] It is beneficial to seamlessly connect the buffer partition and the surrounding wall through the arc edge of the first edge, so as to avoid the disorderly squeezing of solid particles along the surrounding wall into the second space when the container is tilted; a buffer port of a specific shape is formed between the buffer partition and the tilted partition through the straight edge or curved edge of the second edge, so as to avoid excessive accumulation of solid particles in the first space when the container is tilted, thereby resulting in the inability of solid particles to enter the second space in an orderly manner through the buffer port and unable to achieve quantitative interception.

[0015] Furthermore, an overflow hole is provided at the connection between the surrounding wall and the buffer partition, and the overflow hole includes two mutually parallel fold line edges, two mutually parallel first arc edges and second arc edges, the fold line edges extend from the surrounding wall to the buffer partition, the first arc edge is located on the surrounding wall, and the second arc edge is located on the buffer partition and is parallel to the first edge.

[0016] It is beneficial to return the excess solid particles in the second space into the container along the surrounding wall surface through the overflow hole; the overflow hole is extended from the wall surface of the surrounding wall to the plate surface of the buffer partition through the fold line edge; the solid particles are stuck in the center of the first edge through the first arc edge so that they can leak out smoothly; the second arc edge on the buffer partition is parallel to the first edge, so as to avoid that when the angle of the tilted container is less than 45°, the solid particles will also enter the second space along the second arc edge, causing the squeezing of the solid particles in the first space and affecting the buffering effect of the first space.

[0017] Furthermore, the outwardly extending connection seat further includes a first side wall and a second side wall which are parallel to each other, and the container is simultaneously connected between the first side wall and the second side wall.

[0018] It is beneficial to fix the main cover and the container by connecting the outer surface of the first side wall to the main cover and the inner surface of the first side wall to the container; and the second side wall is embedded between the container and the surrounding wall to fix the outward expansion connection seat and the container.

[0019] Furthermore, the inclined partition includes a lower edge, a side edge and an upper edge, the lower edge is a straight edge or a curved edge connected to the bottom wall, the side edges are arc-shaped edges inclined on both sides connected to the surrounding wall, and the upper edge is a straight edge or a curved edge of the material blocking opening.

[0020] It is beneficial to achieve the bottom sealing effect of the third space by connecting the bottom wall through the lower edge and connecting the surrounding wall through the side edge, and to intercept the solid particles falling from the second space into the third space through the upper edge.

[0021] Furthermore, the longitudinal partition is a straight panel or a curved panel, and the inclined partition is a straight panel or a curved panel.

[0022] It is beneficial to keep the filling of solid particles in the third space horizontal by matching the different shapes between the lower edge of the longitudinal partition and the upper edge of the inclined partition, so as to avoid the upper edge of the inclined partition being lower than the lower edge of the longitudinal partition, resulting in insufficient interception of solid particles, or the upper edge of the inclined partition being higher than the lower edge of the longitudinal partition, affecting the speed of solid particles entering the second space from the first space, thereby affecting the one-time interception amount of the third space.

[0023] Furthermore, the cover body also includes a flip cover, which includes a hinge and a closing plug respectively arranged on both sides thereof, the hinge is connected to the main cover to guide the folding direction away from the discharge port, and the closing plug is correspondingly arranged above the discharge port to close the discharge port.

[0024] It is beneficial to seal the cover body through the flip cover, and the flip cover is flipped up unilaterally in the direction away from the discharge port through the hinge to avoid affecting the discharge of the discharge port, and the discharge port is sealed by the closing plug to avoid the spillage of solid particles caused by tilting the container during transportation.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: when the container is dumped with one hand, the solid particles in the container are pre-stored in the second space on the main cover and are intercepted in the third space formed by the outwardly expanded connecting seat, thereby achieving the effect of quantitative material extraction at the discharge port; the buffering of the solid particles when entering the main cover is achieved through the buffer port, so that when the tilt angle of the container is less than 45°, the solid particles are blocked in the first space and cannot enter the second space, thereby preventing the solid particles from directly overflowing from the discharge port when the tilt angle of the container is not enough; the interception of the solid particles is achieved through the blocking port between the inclined partition and the longitudinal partition, and when the tilt angle of the container is greater than 45°, the solid particles enter the third space stably through the first space and the second space in turn and achieve quantitative interception; the discharge of the solid particles is achieved through the discharge port, so that the solid particles intercepted in the third space are all poured out.

DETAILED DESCRIPTION

[0043] The drawings of the present invention are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted. Example 1

[0044] like Figure 1 As shown, this embodiment provides a quantitative cover for a solid container 10, which is a cover body arranged on the container 10, characterized in that the cover body includes a main cover 28 for pre-storage and discharge and an outward expansion connection seat 29 for quantitative discharge, the main cover 28 is provided with a longitudinal partition 281 and partitions into a second space and a fourth space, the outward expansion connection seat 29 is provided with an inclined partition 26 and partitions into a first space and a third space, the bottom of the first space is provided with a buffer port connected to the container 10, and the top is connected to the bottom of the second space; the inclined partition 26 is inclined from the third space to the first space, and forms a pre-storage port with the side wall 292 at the bottom of the second space; the top of the second space is closed, and the bottom is provided with a blocking port 251 connected to the top of the third space; the bottom of the third space is closed, and the top is connected to the bottom of the fourth space, and the top of the fourth space is provided with a discharge port.

[0045] In this embodiment, the first space is a buffer zone 20, the second space is a pre-storage zone 21, the third space is a quantitative zone 22, and the fourth space is a discharge zone 23. When the user lifts the container 10 with one hand for the first time and tilts it, the solid particles enter the buffer zone 20 from the container 10 through the buffer port, and then the pre-storage zone 21 is filled in an orderly manner by the buffer zone 20. The user restores the container 10 to a static state. At this time, the solid particles enter the quantitative zone 22 from the pre-storage zone 21 through the blocking port 251; when the user lifts the container 10 with one hand for the second time and tilts it, the solid particles enter the discharge zone 23 from the quantitative zone 22 and pour out of the cover body through the discharge port. In this embodiment, two cavities in the cover body, namely the main cover 28 and the external expansion connection seat 29, are used to pour out the solid particles, so that the solid particles in the bottle can be stored in the quantitative zone 22 of the third space at the same volume each time, so as to obtain the accurate solid particle volume for the next pouring. The capacity of the quantitative zone 22 determines the basic quantitative value.

[0046] The overlapping distance between the longitudinal partition 281 and the inclined partition 26 in the vertical direction is b, and the gap distance between the pre-storage port 252 and the buffer port in the horizontal direction is a, b≥a.

[0047] In this embodiment, the longitudinal partition 281 is fixed perpendicular to the bottle mouth direction of the main cover. When the container 10 is tilted, the tilt angle of the longitudinal partition 281 is consistent with the tilt angle of the container 10; the gap distance a is used to prevent solid particles from entering the second space. When the tilt angle of the container 10 is less than 45°, most of the solid particles are blocked in the first space and cannot fill the second space, thereby avoiding accidental interception of solid particles due to uncontrolled tilting; when the tilt angle of the container 10 exceeds 45°, the solid particles can flow into the second space through the first space; the overlapping distance b is used to limit the solid particles from entering the third space. When the tilt angle of the container 10 is close to 45°, the filling position of the solid particles in the second space will not exceed the overlapping distance b, thereby preventing them from entering the third space, thereby achieving quantitative interception in the third space when the container 10 is straightened.

[0048] In this embodiment, the operation steps of the main cover 28 intercepting a quantitative solid particle include: the first step, the container 10 is placed normally and the bottle cap is opened; the second step, the container 10 is slightly tilted by one hand, and the solid particles flow into the first space under the action of gravity. Under the action of the buffer partition 27, the solid particles entering the first space are stacked at a specific angle; the third step, the container 10 is continuously tilted more than 45 degrees, the solid particles fill the first space and stably fill the second space, and under the action of the overlapping distance b between the inclined partition 26 and the longitudinal partition 281, the solid particles entering the second space do not exceed the overlapping distance b, so that the solid particles fill the second space without overflowing; the fourth step, the container 10 is slowly returned to the normal position, and the solid particles are divided into two parts by the inclined partition 26, one part is along the inclined partition 26 The solid particles in the third space are intercepted to the third space, and the other part retreats to the first space; in the fifth step, the container 10 is placed back in the upright position, and part of the solid particles are intercepted to fill the third space; in the sixth step, the container 10 is tilted slightly with one hand again, and the solid particles in the container 10 are blocked outside the buffer partition 27 and cannot enter the second space, and the solid particles intercepted in the third space are poured out through the fourth space; in the seventh step, the container 10 is continued to be tilted until it is completely inverted, and the solid particles remaining in the fourth space are completely poured out. At the same time, the remaining solid particles in the container 10 repeat the flow paths of the first, second and third steps to completely fill the first space and the second space; in the eighth step, the container is returned to the upright position again, and the solid particles repeat the flow paths of the fourth and fifth steps to complete the quantitative interception of the solid particles for the next time.

[0049] The main cover 28 also includes a side wall 292, a top wall 291 connected between the side wall 292 and the longitudinal partition 281, and a curved wall 231, wherein the top wall 291 is used for the top closure of the second space, and the curved wall 231 is used for the discharge of the fourth space discharge port; the outward expansion connecting seat 29 also includes a surrounding wall 294 extending from the side wall 292 into the container 10, a bottom wall 293 and a buffer partition 27 connected to the surrounding wall 294, wherein the bottom wall 293 is used for the bottom closure of the third space, and the buffer partition 27 is inclined upward or downward from the surrounding wall 294 and is used for buffering the buffer port of the first space.

[0050] In this embodiment, the side wall 292 is a cylindrical wall, the top wall 291 is an approximately semicircular wall, the longitudinal partition 281 is a vertical plate, the curved wall 231 is a bucket-shaped wall with a smoothly reduced diameter, the discharge port is circular, the surrounding wall 294 is a cylindrical annular wall, the bottom wall 293 is a semicircular wall, the buffer partition 27 is an approximately trapezoidal wall with short sides and curved sides, and the inclined partition 26 is an approximately trapezoidal wall with curved sides.

[0051] In this embodiment, a discharge port is provided at the upper portion of the discharge channel of the main cover 28 and is a circular outlet. The discharge channel is smoothly connected to the circular outlet through a funnel-shaped curved surface, namely, a curved wall 231 .

[0052] In this embodiment, the buffer partition 27 is inclined downward from the surrounding wall 294. When the container 10 is inclined to 45°, the solid particles in the container 10 quickly form an accumulation between the side wall 292 and the buffer partition 27, and together with the accumulation formed between the side wall 292, the buffer partition 27 and the inclined partition 26, form an accumulation area. When the inclination angle of the container 10 is greater than 45°, the solid particles in the container 10 will not continue to be squeezed by other solid particles in the container 10 after forming the accumulation area, so that the solid particles in the accumulation area will no longer continue to feed when filling the pre-storage area 21 in an orderly manner. When the inclination angle of the container 10 is less than 45°, the solid particles in the container 10 cannot form an accumulation area, so the solid particles are intercepted at the buffer port and cannot fill the second space.

[0053] The included angle between the inclined partition 26 and the side wall 292 is A1, 15°<A1<45°, and the included angle between the buffer partition 27 and the side wall 292 is A2, 105°<A2<135°.

[0054] In this embodiment, the included angle A1 between the inclined partition 26 and the side wall 292 is 30°, and the included angle A2 between the buffer partition 27 and the side wall 292 is 120°.

[0055] The buffer partition 27 includes a first edge and a second edge, wherein the first edge is an arc-shaped edge connected to the lower edge of the surrounding wall 294, and the second edge is a straight edge or a curved edge of the buffer port.

[0056] In this embodiment, the first edge is used to connect the surrounding wall 294, and the second edge is used to form a buffer opening. When the second edge is a straight edge, the buffer opening is a trapezoidal opening formed by the second edge as a short side, the arc edge connecting the surrounding wall 294 as two side sides, and the straight edge connecting the bottom wall 293 as a long side.

[0057] In this embodiment, the buffer zone 20 is a feeding channel for solid particles, and a buffer partition 27 corresponding to the channel is provided below the channel, and the arc edge of the buffer partition 27 is connected to the surrounding wall 294. The buffer partition 27 is arranged at an angle, and the plane on which it is located is relatively parallel to or intersects with the quantitative inclined partition 26. The buffer partition 27 is designed at the pressure conduction angle α of the solid particles entering the buffer zone 20 from the container 10, and is suitable for different pouring angles; the buffer partition 27 can prevent the solid particles in the container 10 from continuously exerting pressure on the pre-storage area 21 in an inverted state, resulting in excessive accumulation of powder, and avoid the solid particles in the container 10 from directly flowing to the discharge port through the pre-storage port 252 at a certain angle, resulting in the inability to control the quantitative discharge.

[0058] An overflow hole is provided at the connection between the surrounding wall 294 and the buffer partition 27, and the overflow hole includes two mutually parallel fold line edges, two mutually parallel first arc edges and second arc edges, and the fold line edges extend from the surrounding wall 294 to the buffer partition 27, the first arc edge is located on the surrounding wall 294, and the second arc edge is located on the buffer partition 27 and is parallel to the first edge.

[0059] In this embodiment, the overflow hole is formed by two fold line edges and two arc edges, and is arranged at the intersection of the side edge of the buffer partition 27 and the bottom edge of the surrounding wall 294. It can be used to discharge the last residue in the cover body and the container 10 in the final stage of use of the solid granular product.

[0060] The outwardly extending connection seat 29 further includes a first side wall and a second side wall which are parallel to each other, and the container 10 is simultaneously connected between the first side wall and the second side wall.

[0061] In this embodiment, the first side wall is a cylindrical annular wall surface, and the second side wall is also a cylindrical annular wall surface. The first side wall is used to connect the main cover 28 and the container 10, and the second side wall is used to connect the surrounding wall 294 and the container 10. The outward expansion connection seat 29 is provided at the lower end of the main cover 28, and is an outward expansion step. The second side wall fixed to the bottle mouth of the container 10 is provided in the step, so that the inner diameter of the bottle mouth can correspond to the size of the inner cavity of the main cover 28.

[0062] The inclined partition 26 includes a lower edge, a side edge and an upper edge. The lower edge is a straight edge or a curved edge connected to the bottom wall 293, the side edges are arc-shaped edges inclined at both sides connected to the surrounding wall 294, and the upper edge is a straight edge or a curved edge of the material blocking opening 251.

[0063] In this embodiment, the inclined partition 26 is connected to the bottom wall 293 and the surrounding wall 294, so that the solid particles entering the quantitative area 22 will not easily return to the container 10 or the pre-storage area 21. When the upper edge is the straight edge of the blocking opening 251, the inclined partition 26 is a straight plate; when the upper edge is the curved edge of the blocking opening 251, the inclined partition 26 is a curved plate with both ends higher than the middle. The pre-storage opening 252 between the inclined partition 26 and the right side of the surrounding wall 294 is a channel for solid particles to enter the pre-storage area 21. The size of the pre-storage opening 252 determines the speed at which the solid particles flow into the pre-storage area 21.

[0064] The longitudinal partition 281 is a straight plate or a curved plate, and the inclined partition 26 is a straight plate or a curved plate.

[0065] In this embodiment, when the longitudinal partition 281 is a straight panel, the inclined partition 26 can be either a straight panel or a curved panel; when the longitudinal partition 281 is a curved panel, the inclined partition 26 is a straight panel.

[0066] In this embodiment, when the longitudinal partition 281 is a straight plate, the cross section of the longitudinal partition 281 is a straight line, the center of the straight line is in the middle of the cover body, and the upper edge of the inclined partition 26 of the quantitative zone 22 is also a straight line. The two sides of the blocking port 251 are arc segments connecting the surrounding wall 294, the left side is the straight lower edge of the longitudinal partition 281, and the right side is the straight upper edge of the inclined partition 26. After the solid particles enter the quantitative zone 22, the tilt direction of the container 10 is to the left. Even if the tilt angle is not aligned with the discharge port, the solid particles will not return to the pre-storage zone 21 and the buffer zone 20. At the same time, no new solid particles will enter the pre-storage zone 21 and the buffer zone 20. The solid particles move along the surrounding wall 294, the inclined partition 26, and the bottom wall 293 of the quantitative zone 22 to the side wall 292 and the curved wall 231 until they completely flow out of the discharge port.

[0067] In this embodiment, when the longitudinal partition 281 is a curved plate, the cross section of the longitudinal partition 281 is an arc, and the center of the arc is on the right side of the cover. The upper edge of the inclined partition 26 of the quantitative zone 22 is also an arc, and is arranged substantially parallel to the arc of the longitudinal partition 281. The arc design makes the amount of material intercepted at different bottle holding angles β tend to be consistent, which is conducive to reducing the quantitative deviation caused by different bottle holding angles β during use.

[0068] The cover body also includes a flip cover 24, which includes a hinge and a closure plug 241 respectively arranged on both sides thereof. The hinge is connected to the main cover 28 to guide the folding direction away from the discharge port, and the closure plug 241 is correspondingly arranged above the discharge port to close the discharge port.

[0069] In the present embodiment, the sealing method of the discharge port of the flip cover 24 is a flip cover 24 with a hinge, and a closing plug 241 is provided at the position corresponding to the discharge port. The hinge is provided on the right side of the main cover 28, that is, the end away from the discharge port. When pouring in actual use, the opened flip cover 24 corresponds to the discharge port up and down, so that the discharge port is naturally at the bottom, and at the same time prompts the user the correct method of use. Example 2

[0070] Different from Example 1, in this embodiment, the buffer partition 27 is inclined upward along the surrounding wall 294, the buffer partition 27 is perpendicular to the inclined partition 26, and the minimum distance S1 of the buffer port in the horizontal direction is equivalent to the minimum distance between the inclined partition 26 and the side wall 292 in the horizontal direction, that is, the diameter S2 of the entrance of the pre-storage area 21.

[0071] In this embodiment, the upper edge of the inclined partition 26 of the quantitative zone 22 and the lower edge of the longitudinal partition 281 are at a considerable height H and are staggered by a certain horizontal distance S. The horizontal distance S determines the interception amount of solid particles. The minimum distance S1 between the buffer partition 27 and the inclined partition 26 of the quantitative zone 22 is comparable to the minor diameter S2 of the entrance of the pre-storage zone 21, so that the solid particles can smoothly enter the pre-storage zone 21.

[0072] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the claims of the present invention shall be included in the protection scope of the claims of the present invention.
