Description

Technical Field

[0001] This utility model generally relates to the field of packaging technology, and more specifically, to a flow-guiding adapter capable of multi-directional flow guidance and a container including the adapter. Background Technology

[0002] In the field of packaging technology, such as in the packaging of liquid detergents, a flow guide is typically installed between the container body and the lid to guide the liquid flow when pouring. A conventional flow guide's nozzle includes a tongue-shaped flow channel. This means the flow guide has only a very specific flow direction. When holding the container, the user needs to hold the part of the container directly opposite the flow direction to ensure smooth liquid flow. If the hand is not positioned correctly, there is a risk that when pouring, the liquid inside the container may not flow out along the flow channel of the nozzle but overflow into unwanted areas.

[0003] On the other hand, most users tend to keep the container after using up the detergent inside, then buy a repackaged copy of the same detergent, refill the original container, and reuse it. Conventional dispensing adapters are generally designed to be securely and tightly connected to the container, facilitating only one-way dispensing from the inside to the outside. Refilling requires aligning the dispensing nozzle with the container and holding the dispensing bag until filling is complete. This often results in misalignment and spillage, and prolonged holding can cause hand fatigue. A few users remove the dispensing adapter from the container before refilling, which compromises the seal and security of the connection between the adapter and the container.

[0004] Therefore, further improvements are needed to the drainage adapter so that users can smoothly drain the liquid in the container regardless of where they hold it when pouring. In addition, the container can be easily refilled without removing the drainage adapter from the container, thus avoiding additional handling work and operator fatigue. Utility Model Content

The following description of the embodiments of this utility model with reference to the accompanying drawings is intended to explain the technical content of this utility model and should not be construed as a limitation thereof.

[0034] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a full understanding of exemplary embodiments of the present invention. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0035] This utility model describes a drainage adapter, comprising: a cylindrical base, wherein a container connection portion and a cap connection portion are respectively provided on both sides of the base in the axial direction; and a drainage nozzle, wherein the drainage nozzle is disposed on the side of the base near the cap connection portion and extends axially from the inside of the base to the outside of the base, wherein the drainage nozzle is cylindrical; and a liquid guiding component, wherein the liquid guiding component is disposed on the side of the base near the container connection portion and communicates with the drainage nozzle, wherein a plurality of water outlet holes are provided on the portion of the liquid guiding component near the drainage nozzle.

[0036] This utility model also describes a container, including a container body; a container lid; and the aforementioned drainage adapter; wherein the container body is connected to the container connecting portion of the drainage adapter, and the container lid is connected to the lid connecting portion of the drainage adapter.

[0037] The advantages of this drainage adapter are: users can drain the liquid in the container smoothly regardless of where they hold the container when pouring it; in addition, the container can be easily refilled without removing the drainage adapter from the container, thus avoiding additional processing work and operational fatigue.

[0038] The drainage adapter and container provided by this utility model can be used to package a variety of liquid products. Specifically, the container of this invention can hold the following products: cleaning products, disinfectants, dishwashing solutions, laundry detergents, fabric conditioners, fabric dyes, surface protectants, hair care products, food, beverages, pharmaceuticals, supplements, automotive supplies, etc.

[0039] Figure 1 This is a perspective view of a container according to an embodiment of the present invention. Figure 1 As shown, a container according to an embodiment of the present invention includes a container body; a container lid (not shown); and a drain adapter 100; wherein the container body is connected to the container connecting portion 111 of the drain adapter 100, and the container lid is connected to the lid connecting portion 112 of the drain adapter 100. When pouring the container, if the tilt angle of the container body is relatively gentle, the liquid contained in the container will slowly flow out from the cylindrical drain nozzle 120 of the drain adapter 100. Since the drain nozzle 120 is cylindrical and non-directional, the user can freely pick up the container and pour it directly.

[0040] Figure 2 This is a perspective view of a drainage adapter 100 according to an embodiment of the present utility model; Figure 3 This is a cross-sectional view of a drainage adapter 100 according to an embodiment of the present invention.

[0041] As shown in the figure, a flow-guiding adapter 100 according to an embodiment of the present invention includes: a cylindrical base 110, wherein a container connecting portion 111 and a cap connecting portion 112 are respectively provided on both sides of the base 110 in the axial direction; and a flow-guiding nozzle 120, wherein the flow-guiding nozzle 120 is disposed on the side of the base 110 near the cap connecting portion 112 and extends axially from the interior of the base 110 to the exterior of the base 110, wherein the flow-guiding nozzle 120 is cylindrical; and a liquid guiding component 130, wherein the liquid guiding component 130 is disposed on the side of the base 110 near the container connecting portion 111 and communicates with the flow-guiding nozzle 120, wherein a plurality of water outlet holes 131 are provided on the portion of the liquid guiding component 130 near the flow-guiding nozzle 120.

[0042] When the user pours the container, the presence of the liquid guiding component 130 ensures that the liquid inside the container can only reach the drain nozzle 120 through the multiple water outlets 131 on the liquid guiding component 130, thereby limiting the flow. Even if the user cannot control the pouring angle, the liquid inside the container will not flow out too much.

[0043] According to an exemplary embodiment of the present invention, the plurality of water outlet holes 131 are centrally symmetrically distributed along the periphery near the portion of the drain nozzle 120. This arrangement of the plurality of water outlet holes 131 has the effect that, when the user pours the container, liquid flows out through one or more of the plurality of water outlet holes 131, while others of the plurality of water outlet holes 131 can serve as vents to balance the air pressure inside and outside the container, thus ensuring smooth liquid flow.

[0044] According to an exemplary embodiment of the present invention, the liquid guiding component 130 includes a dome-shaped sheet 134 protruding toward the cap connection portion 112, and the water outlet 131 is disposed at the periphery of the sheet 134. The shape of the dome-shaped sheet 134 facilitates the flow of liquid toward the water outlet 131 at the periphery of the sheet 134 when filling the container.

[0045] According to an exemplary embodiment of the present invention, the sheet-like member 134 is provided with a plurality of drainage ribs 132 extending radially from the center to the periphery.

[0046] According to an exemplary embodiment of the present invention, the drain nozzle 120 further includes a venting channel 121. The venting channel 121 is disposed on the cylindrical wall of the drain nozzle 120 and extends along the length of the drain nozzle 120, connecting to the side of the base 110 near the container connection portion 111. The venting channel 121 is abutted against the cylindrical wall of the drain nozzle 120 and is designed to be very long and narrow. When the user fills the container, the filling liquid is completely poured into the cylindrical drain nozzle 120, making it less likely to clog the venting channel 121. The number and arrangement of the venting channels 121 can be very flexible. For example, as shown in the figure, the drain adapter 100 of the present invention includes two sets of venting channels 121, each set including two venting channels 121. Thus, even if one venting channel 121 is accidentally blocked, the other venting channels 121 remain unobstructed, thus not affecting the refilling of the container. As will be known to those skilled in the art, the drainage adapter 100 of this invention may include a different number of ventilation channels 121 than the two sets of four ventilation channels 121. As shown in the figure, the two sets of ventilation channels 121 of the drainage adapter 100 of this invention are arranged side by side. As will be known to those skilled in the art, when multiple ventilation channels 121 are provided, the multiple ventilation channels 121 may not be arranged adjacently, but may be spaced apart along the inner periphery of the cylindrical wall.

[0047] Figure 4 This is a perspective view of a drainage adapter 100 according to another embodiment of the present invention; Figure 5 This is a cross-sectional view of a multi-directional drainage adapter 100 according to another embodiment of the present invention.

[0048] As shown in the figure, according to another exemplary embodiment of the present invention, the drain nozzle 120 is a long and thin cylindrical shape, and the liquid guiding component 130 is also cylindrical and sleeved on the outside of the drain nozzle 120. The end of the drain nozzle 120 inside the base 110 is connected to the free end of the liquid guiding component 130 and forms an integral part. The water outlet 131 is provided at the connection between the drain nozzle 120 and the liquid guiding component 130.

[0049] According to an exemplary embodiment of the present invention, a baffle 133 is provided on the side of each water outlet 131 away from the liquid guiding member 130. The baffle 133 is provided to prevent liquid in the container from clogging the water outlet 131 when it flows out.

[0050] According to an exemplary embodiment of the present invention, the free end of the drainage nozzle 120 has a flange 122. As shown in the figure, the flange 122 flares outward to facilitate refilling of the container.

[0051] According to an exemplary embodiment of the present invention, when the drainage nozzle 120 protrudes to the outside of the base 110, it is inclined at 1°-32° toward the centerline of the base 110.

[0052] Figure 6 This is a perspective view of a multi-directional drainage adapter 100 according to another embodiment of the present utility model; Figure 7 This is a cross-sectional view of a multi-directional drainage adapter 100 according to another embodiment of the present invention.

[0053] As shown in the figure, according to an exemplary embodiment of the present invention, the liquid guiding component 130 includes a funnel-shaped channel portion 137 and a sheet-shaped fixing portion 135, wherein the larger diameter end of the funnel-shaped channel portion 137 is lower than the free end of the drain nozzle 120 extending to the outside of the base 110, the smaller diameter end of the funnel-shaped channel portion 137 extends toward the side of the base 110 near the container connection portion 111, the fixing portion 135 is arranged around the funnel-shaped channel portion 137, and the water outlet 131 is provided on the fixing portion 135.

[0054] As shown in the figure, the fixing part 135 is provided at the neck of the funnel-shaped channel of the liquid guiding component 130, and the periphery of the fixing part 135 is integrally formed with the base 110. The number of water outlet holes 131 is 2.

[0055] As shown in the figure, there is a gap between the larger diameter end of the funnel-shaped channel portion 137 and the free end of the drainage nozzle 120. This gap forms the drainage nozzle 120 of the drainage adapter 100.

[0056] As shown in the figure, a cylindrical channel portion 136 is also provided at the smaller diameter end of the funnel-shaped channel portion 137.

[0057] When the user pours out the container, the liquid inside the container flows through a portion of the water outlet 131 on the fixing part 135 and flows out of the container through the gap. When the user fills the container, the liquid flows into the container from the funnel-shaped channel of the liquid guiding part 130. If the liquid accidentally enters the gap, it will eventually flow into the container through the water outlet 131 on the fixing part 135.

[0058] According to one aspect of the present invention, a container is provided, such as... Figure 1 As shown, it includes: a container body; a container lid; and the aforementioned drainage adapter 100; wherein the container body is connected to the container connecting portion 111 of the drainage adapter 100, and the container lid is connected to the lid connecting portion 112 of the drainage adapter 100.

[0059] Figure 8This is a perspective view of a multi-directional flow guide adapter 100 including a flow-blocking device according to an embodiment of the present invention.

[0060] According to an exemplary embodiment, the flow-guiding adapter 100 of this utility model further includes a flow-blocking device 200, which is disposed at the end of the liquid guiding component 130 near the container side, for controlling the speed at which liquid in the container flows out of the liquid guiding component 130 when the container is poured.

[0061] The flow-blocking device 200 includes a cage 210 and a ball plug 220. The ball plug 220 can roll freely within the cage 210. The cage 210 is connected to the liquid guiding component 130. When the container is placed upright, the cage 210 is located below the liquid guiding component 130. Under the action of gravity, the ball plug 220 is located at the bottom of the cage 210, spaced apart from the liquid guiding component 130, and does not obstruct the liquid guiding component 130, allowing liquid to flow into the container through the liquid guiding component 130. When the container is placed upside down, the cage 210 is upside down above the liquid guiding component 130. Under the action of gravity, the ball plug 220 rolls down to the connection between the cage 210 and the liquid guiding component 130, blocking the liquid guiding component 130, so that the liquid in the container cannot flow out of the container through the liquid guiding component 130.

[0062] In actual use, when the user pours liquid, the container changes from a horizontal position to an inverted tilted position. Under the action of gravity, the ball plug 220 gradually rolls to the point where the cage 210 is connected to the liquid guiding component 130, so that the liquid can no longer flow out of the container through the liquid guiding component 130, thereby controlling the flow rate of the liquid.

[0063] The diameter of the ball plug 220 needs to be set to be larger than the diameter of the smaller end of the liquid guiding component 130, and it can roll freely up and down.

[0064] The cage frame 210 is cylindrical in shape. Inside the cage frame 210, a limiting member 230 is provided. The limiting member 230 is configured to define a straight path extending from the top to the bottom of the cage frame 210. The ball plug 220 is restricted by the limiting member 230 within the straight path and can only roll along the straight path between the top and bottom of the cage frame 210.

[0065] Specifically, the limiting member 230 includes three limiting pieces 231, which are angled to each other in the cage 210, wherein the included angle between adjacent limiting pieces 231 is 120°. The three limiting pieces 231 define the straight path at their intersection.

[0066] The cage 210 has a slot at its top, into which the smaller diameter end of the liquid guiding component 130 can be inserted.

[0067] The drainage adapter provided according to the foregoing exemplary embodiments of the present invention has the following advantages: when the user pours the container, the liquid in the container can be drained smoothly regardless of the angle at which the user holds the container, thus providing the user with a better user experience. In addition, the container can be refilled directly without removing the drainage adapter from the container, which will not cause additional processing work and operational fatigue, and facilitates the user's reuse of the container.

Rather, unless otherwise stated, each dimension is intended to represent the listed value and a range of functionally equivalent values ​​around that value. For example, a dimension disclosed as 1°–32° is intended to represent “approximately 1°–32°”.

[0069] While some embodiments of the present invention have been shown and described, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
