Description

Technical Field

[0001] The present invention relates to the field of bottled water, in particular to a barrel cover of a water dispenser barrel that is easily penetrated and the water dispenser barrel. Background Art

[0002] As we all know, the barrel lids for water dispensers (commonly known as smart lids) are gradually being updated and upgraded, and their structures are also being upgraded. The most familiar one is the split-type smart lid previously used on 19L dispensers. This smart lid consists of a barrel lid with a recessed end surface, the bottom of which forms the water outlet, and a detachable inner cover above the outlet. After the smart column of the water dispenser breaks through the white inner cover, the inner cover easily floats in the water, leaving a negative impression on users.

[0003] In recent years, the split-and-assembled smart lid has been replaced with a one-piece, one-piece smart lid. This lid features a recessed section on the end face, with the bottom of the recess forming a cover body that's integral with the rest of the lid. This one-piece lid has largely resolved the issue of the "white inner lid floating in water" problem. However, its downside is that it requires significant force to penetrate the lid body at the bottom of the recess, leading to widespread consumer complaints. This type of smart lid has the inherent drawback of requiring significant force to penetrate. When used with a relatively heavy 19L bottle of water (the weight of 19L of water plus the barrel itself is nearly 20KG), consumers don't need to exert much force; the smart lever on the water dispenser can penetrate the lid body at the bottom of the recess without expending significant force.

[0004] However, in recent years, bottled water is transitioning to small PET bottled water, and the use of integrated smart caps has gradually switched to supporting small bottled water. For example, when applied to 5L PET bottled water, the weight advantage of the 20KG basic weight is lost during the process of placing the bottled water in the water dispenser, highlighting the shortcoming of the integrated smart cap, which is that it is difficult to pierce the top. According to industry observations, this shortcoming has caused an increasing number of customer complaints, and the experience of using the water dispenser is also relatively poor, mainly manifested in the difficulty of piercing the top, or the need for two or more piercings.

[0005] The smart cover for bottled water has a shortcoming that it is difficult to break through the water dispenser. Looking at the smart covers currently available on the market, most of their structural principles are: the connection between the side wall of the recess in the center of the cover and the bottom surface of the recess adopts a relatively thin plastic material (usually 0.1-0.3mm), and a raised structure is provided on the edge of the upper surface of the bottom surface of the recess for first contact with the smart rod for breaking through. However, in order to prevent the bottom surface of the recess from falling into the water after being broken through, a local hinge connection point is provided on the lower surface at the intersection of the side wall and the bottom surface. The plastic material of this hinge connection point is relatively thick (usually reaching 0.5-1.0mm). Through the hinge connection point, the bottom surface is forced to connect to the side wall after being broken through, so it will not fall into the water.

[0006] However, it is precisely because of the existence of this hinge connection point, and the presence of a bump located at the bottom edge of the recess, that the ball head of the Smart Rod easily slides and drifts to the opposite side of the bump when it first contacts the bump. This is usually the thickest hinge connection point, so its penetration force reaches its maximum. Only when the Smart Rod contacts the bump quickly, accurately, and fiercely, and with good timing (the Smart Rod will not slide or drift), does the penetration force achieve the original designer's intention of "concentrating the force on the bump breakthrough point." Otherwise, once the Smart Rod drifts to the opposite side, its penetration force changes from minimum to maximum. Of course, some designers have also discovered the shortcomings and assume that the Smart Rod will slide to the opposite side after first contacting the bump. Therefore, they set the hinge on the same side of the bump to minimize the penetration force. However, is the truth really that the smart rod ball head will drift 100% after it first contacts the eccentrically set bump? The answer is very obvious. Whether the smart rod ball head will drift when it contacts the bump is a very complex probabilistic event, that is, there is always a certain probability that the smart rod will drift to the thickest part of the hinge. This is why it is difficult to break through.

[0007] At the same time, another disadvantage is that when the user opens the water dispenser, the vertical downward force that the user ideally applies to break through the bottom surface 1 of the central recess of the lid is greatly weakened. This is because the structure of the ball head of the smart rod 2 and the convex point eccentrically set at the bottom edge of the recess decomposes the vertical downward force F applied by the consumer. Here, only one component F1 acts on the protrusion 3 to form a breakthrough. Through the decomposition of force (see attached Figure 1 ), F1 = F*cosα. The formula shows that the smaller the angle α, the larger F1. When F1 is zero, that is, when the bump is in the center of the groove, F1 equals F, reaching its maximum. This means that according to traditional solutions, even if the bump is ideally designed to break through, a greater force F is required, as a larger force component acts on the bump to break through.

[0008] In summary, due to the structural design, the smart rod may be pushed against the thick hinge with a certain probability, or the consumer's force may be greatly weakened due to the eccentric design of the protrusion. In short, the consumer will need to use greater force to break through the bottom of the groove. Summary of the Invention

[0009] The present invention aims to provide a bucket cover for a water dispenser and a water dispenser bucket, so as to improve the problem in the prior art that the bucket cover of the water dispenser bucket is not easily punctured by the smart rod of the water dispenser.

[0010] According to one aspect of an embodiment of the present invention, the present invention provides a barrel cover for a water dispenser bucket, wherein a recess is provided on the top surface of the barrel cover, and a strength weakening portion is provided on the bottom surface of the recess, wherein the strength weakening portion is lower than the remaining area of ​​the bottom surface, and the strength weakening portion divides the bottom surface into at least two areas.

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Figure 2 The figure shows a three-dimensional structure diagram of the bucket cover of the water dispenser bucket of this embodiment. Figure 3 The bottom portion of the bucket cover of the water dispenser of this embodiment is shown in FIG. Figure 4 1 shows a schematic diagram of the top structure of the barrel cover of this embodiment, Figure 5 A schematic cross-sectional structure diagram of the barrel cover of this embodiment is shown.

[0040] Combine Figures 2 to 5 As shown, the top surface 11 of the lid 1 of the water dispenser bucket of this embodiment is provided with a recess 12. A strength-reducing portion 4 is provided on the bottom surface 2 of the recess 12. The strength-reducing portion 4 is lower than the remaining area of ​​the bottom surface 2 and divides the bottom surface 2 into at least two sector-shaped areas. Optionally, the diameter of the bottom surface 2 is 18.6 mm.

[0041] When the bottled water is placed on the water dispenser, the smart rod of the water dispenser can first puncture the weakened part 4. Under the action of stress, the bottom surface 2 of the recess 12 can be easily cracked from the punctured part, thereby improving the problem in the prior art that the integrated barrel cover is not easily pushed open by the smart rod.

[0042] In some embodiments, at least two weakened portions 4 extend from the same starting point on the bottom surface 2 in different directions toward the edge of the bottom surface 2. Preferably, the weakened portion 4 extends from the starting point to the edge of the bottom surface of the recess 12. Preferably, the number of the weakened portions 4 can be 3 to 9.

[0043] like Figure 2 and 4 As shown, in this embodiment, three weakening portions 4 are provided on the bottom surface 2 of the recess 12. The starting point of the weakening portion 4 is located in the middle of the bottom surface 2 of the recess 12. The weakening portions 4 are evenly spaced around the starting point. The three weakening portions 4 divide the bottom surface 2 of the recess 12 into three sector-shaped areas, each with a central angle of 120°.

[0044] Optionally, the thickness of the weakened portion 4 is 0.05 to 0.25 mm. Preferably, the thickness of the weakened portion 4 is 0.15 mm.

[0045] The connection portion 5 between each area of ​​the bottom surface 2 of the recess 12 divided by the strength weakening portion 4 and the peripheral surface of the recess 12 includes a first connection portion 51 and a second connection portion 52 arranged along the circumference of the recess 12 with the first connection portion 51 and weaker in strength than the first connection portion 51.

[0046] The first connection portion 51 is located in the middle of the region along the circumference of the recess 12 , and the second connection portion 52 extends from the first connection portion 51 to the end of the region along the circumference of the recess 12 .

[0047] The thickness of the first connection portion 51 is 0.15 to 0.5 mm, and the thickness of the second connection portion 52 is 0.05 to 0.25 mm.

[0048] The connecting parts 5 are arranged in a thin-thick-thin pattern. After the bottom surface 2 of the recess 12 is punctured by the rod, the bottom surface 2 is divided into multiple sector-shaped areas. Each sector is connected to the perimeter of the recess 12 via a first connecting part 51 to prevent the broken areas from falling into the water. The second connecting part 52 reduces the connection strength between the bottom surface 2 and the perimeter of the recess 12, further reducing the force that would cause the bottom surface 2 of the recess 12 to be punctured.

[0049] The connection between the bottom surface 2 and the peripheral surface of the recess 12 is formed by connecting multiple connecting portions 5 in sequence. The shape of the connection between the bottom surface 2 and the peripheral surface can be circular or polygonal. In this embodiment, the connection between the bottom surface 2 and the peripheral surface of the recess 12 is a regular 9-sided polygon. The connecting portion 5 of each sector-shaped area includes three sides of a regular 9-sided polygon, of which the middle side is the first connecting portion 51, and the other two sides are the second connecting portions.

[0050] like Figures 2 to 5 As shown, a protrusion 3 is provided on the bottom surface 2 of the recess 12. When the bottled water is placed on the water dispenser, the protrusion 3 on the bottom surface of the recess 12 first contacts the smart rod of the water dispenser, so that the force on the bottom surface 2 of the recess 12 is concentrated at the position of the protrusion 3, which helps to reduce the force that punctures the bottom surface 2 of the recess 12.

[0051] The protrusion 3 is arranged at one end of the area divided by the strength weakening part 4, which is adjacent to the above-mentioned starting point. The end of the divided area adjacent to the starting point is the tip. It is more beneficial to concentrate the force applied by the smart rod to the bottom surface 2 of the recess 12 on the tip point of the area and reduce the force of puncturing the bottom surface 2 of the recess 12.

[0052] The protrusions 3 include a first protrusion 31 provided on one region and a second protrusion 32 provided on another region, and the first protrusion 31 is higher than the second protrusion 32 .

[0053] In this embodiment, each of the three sector-shaped regions is provided with a first protrusion 31, a second protrusion 32, and a third protrusion 33. The height of the first protrusion 31 is h1, the height of the second protrusion is h2, and the height of the third protrusion is h3.

[0054] The first protrusion 31 is higher than any other protrusions, so that the force applied by the smart rod on the bottom surface 2 of the recess 12 is concentrated on the protrusion 3 in a sector-shaped area.

[0055] The bottom surface of the recess 12 may be a plane, and the bottom surface 12 of the recess 12 may be convex toward the top surface 11 of the barrel cover 1 , or may be concave toward a direction away from the top surface 11 of the barrel cover 1 .

[0056] In this embodiment, the bottom surface of the recess 12 is recessed in a direction away from the top surface 11 of the barrel cover 1. The bottom surface 2 of the recess 12 includes a conical portion 21 inclined toward the center of the recess 12 in a direction away from the top surface 11 of the barrel cover 1, and a flat portion 22 provided at one end of the conical portion 12 away from the end surface 11 of the barrel cover 1.

[0057] Combine Figure 5 and 6 As shown, the bottom surface 2 of the recessed portion 12 of this embodiment includes a gently tapered portion 21 and a flat portion 22 connected to the bottom end of the tapered portion 21 .

[0058] In this embodiment, the inner diameter of the recess 12 tapers toward the bottom surface 12, and the angle between the recess's perimeter and the horizontal plane is 90-100°. The recess 12 is generally shaped like a bell mouth. The upper portion of the recess 12 is a trapezoid with a base radius of 18.6 mm and an opening angle of 90-100°. The lower portion is a composite surface composed of a slightly flattened conical portion 21 and a flat surface portion 22.

[0059] The biggest advantage of this design is: taking into full consideration that the vast majority of smart rods 6 on the market are cylinders with a certain diameter plus a ball head or a cone head or the front end of the ball head is horizontal, the design goal of the shape of the recess 12 is to fit the shape of the smart rod 6 as perfectly as possible. Compared with the traditional flat-bottom recess, the cooperation between the smart rod 6 and the recess 12 is more prominent in seamless docking. Under the premise that the depth of the recess is the same as that of the prior art, the effective depth of the smart rod 6 buried in the recess in this solution is greater. In addition, the bottom surface 2 of the recess 12 fits the shape of the head of the smart rod 6, which significantly reduces the possibility of shaking and drifting of the smart rod 6 when it is introduced into the protrusion of the recess 12. The advantages described here are only from the perspective of the external contour design, through qualitative analysis, and the working principle will be further explained later through the depth of the groove side wall, including the height of the bump, and the size of the ball head of the smart core.

[0060] like Figure 6As shown, the relationship between the depth H0 of the recess 12 and the height dimension S1 of the ball head of the smart rod 6 is set to: H0>S1+h1; (h1 is the height of the maximum protrusion). The purpose of this setting is to ensure that the ball head of the smart rod 6 is completely located in the recess 12 when it is introduced into the recess 12, and then to ensure that the smart rod 6 plays a good centering guide when it contacts the protrusion 3 in the recess 12, and the smart rod 6 will not be difficult to center and drift and shake during operation due to the ball head being exposed outside the recess 12.

[0061] Optionally, H0>S1+h1, the value is H0-S1-h1=1mm;

[0062] Furthermore, the height dimension S1 of the ball head of the smart rod 6 is derived from the actual measured dimensions of the smart rod 6 of the popular water dispenser of the mainstream brand in the market with the largest market share.

[0063] Furthermore, in order to ensure that the smart rod 6 contacts the protrusion 3 immediately when it is introduced into the recess 12, the bottom surface 2 of the recess 2 includes a conical portion 21. Furthermore, the conical portion of the bottom surface 2 of the recess 12 is relatively flat, that is, the conical surface R ≥ S1, and the conical surface R ≥ S1 is also formed by h 1 The size is adjusted to fully ensure that the smart rod 6 contacts the protrusion 3 at the first time.

[0064] And by adjusting the relationship H0>S1+h1, the smart rod 6 can be extended into the recess 12 as much as possible and the drift and shaking can be reduced.

[0065] The principle of the smart cap of the present invention can be widely applied to the threaded caps currently available on the market, such as PET bottled water bottle caps, 38-mouth smart caps, 48-mouth smart caps, 55-mouth smart caps, etc. It can also be applied to bottled water smart caps without threads, such as 19L bottled water smart caps, etc.

[0066] According to another aspect of the present invention, this embodiment further provides a water dispenser bucket, which includes the above-mentioned bucket cover and the water bucket.

[0067] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
