Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to an easy-to-break top-penetrating cap. Background Art

[0002] At present, 5-gallon barreled drinking water and small-capacity bottled drinking water of more than 4 liters are becoming more and more popular because of their hygiene and convenience. The bottle caps are made of PE material by injection molding. In order to meet the requirements of being installed on water dispensers, the top of the bottle cap of this type of drinking water barrel (bottle) on the market has a concave hole in the middle, and the top-penetrating piece at the bottom of the concave hole is a flat structure and is weakly connected to the side of the concave hole so that it can break through the smart column of the water dispenser, thereby allowing water to flow from the bucket into the water dispenser.

[0003] When using a bottled water dispenser, when the smart column breaks through the lid, the first point where the front end of the smart column contacts the top-breaking piece at the bottom of the lid's recessed hole is not necessarily the breaking point on the top-breaking piece. Most of the time, it is in the center of the top-piercing piece. At this time, the penetration force is dispersed to the surroundings. When the penetration force reaches a certain level, the weak connection between the top-piercing piece and the hole wall will be broken. At this time, the penetration force required is often very large, and a large external force is needed to penetrate the top-piercing piece. In addition, when the smart column acts on the center of the top-piercing piece, it can slide in any direction on the top-piercing piece. If the smart column slides toward the thicker area where the top-piercing piece connects to the groove, it may cause the smart column to bend or be damaged, thereby affecting the normal use of the water dispenser. Utility Model Content

[0004] In view of this, the present invention proposes an easy-to-break top-penetration cover to solve the problem that the existing top-penetration cover requires a large penetration force during the penetration process.

[0005] The technical solution of the present utility model is achieved as follows:

[0006] The utility model provides an easy-to-break top-penetrating cover, comprising a cover body and a top-penetrating piece. The center of the top surface of the cover body is recessed downward to form a mounting ring with a cylindrical structure. The top-penetrating piece is sealed to the end of the mounting ring. A tearing portion is formed between the top-penetrating piece and the inner wall of the mounting ring. A groove is provided on the upper surface of the top-penetrating piece. The groove extends from the center of the top-penetrating piece to the edge of the top-penetrating piece. The bottom surface of the groove is an inclined structure, and the bottom surface height of the groove gradually decreases from the center of the top-penetrating piece to the edge of the groove.

[0007] On the basis of the above technical solution, preferably, the groove includes a positioning section and a guide section, the positioning section is located at the center of the top-penetrating piece, the positioning section is semicircular in shape, the guide section is strip-shaped, one end of the guide section is tangentially connected to the positioning section, and the other section is connected to the edge of the top-penetrating piece.

[0008] Furthermore, preferably, the diameter of the positioning section is greater than or equal to the diameter of the smart column.

[0009] Furthermore, preferably, a semicircular protrusion is provided at the center of the upper surface of the top-penetrating piece, and the semicircular protrusion surrounds the outer side of the positioning section.

[0010] Based on the above technical solution, preferably, the vertical height from the lowest end of the bottom surface of the groove to the upper surface of the top-penetrating piece is less than or equal to half the thickness of the top-penetrating piece.

[0011] On the basis of the above technical solution, preferably, it also includes a connecting piece, which is located on the lower surface of the top-penetrating piece and corresponds to the groove above and below. The connecting piece is fixedly connected to the lower surface of the top-penetrating piece, and one end of the connecting piece is fixedly connected to the end of the mounting ring away from the guide section.

[0012] Preferably, the thickness of the tear portion is half the thickness of the top-penetrating sheet.

[0013] Preferably, the inner side surface of the cover body is provided with a threaded portion.

[0014] Preferably, the inner top surface of the cover body is protruding downward to form an annular sealing portion, and the annular sealing portion is located on the outside of the mounting ring.

[0015] Preferably, the outer side surface of the cover is provided with anti-slip grooves.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) A groove is provided on the upper surface of the top-penetrating sheet, the groove extends from the center of the top-penetrating sheet to the edge of the top-penetrating sheet, the bottom surface of the groove is an inclined structure, and the bottom surface height of the groove gradually decreases from the center of the top-penetrating sheet to the edge of the groove. When the smart column applies a vertical upward opening force to the top-penetrating sheet, it will slide from the center of the top-penetrating sheet to the edge along the inclined direction of the groove, so that the penetration force of the smart column is concentrated in the groove near the edge area of the top-penetrating sheet, and the edge of the top-penetrating sheet is subjected to higher local pressure, making it easier to tear and break the edge of the top-penetrating sheet quickly, thereby reducing the required penetration force.

[0018] (2) By configuring the groove to consist of a positioning section and a guide section, wherein the positioning section is semicircular in shape, the smart column of the water dispenser can accurately act on the center of the positioning section when it contacts the top-penetrating piece. The strip-shaped design of the guide section ensures that when the penetration force is transferred from the positioning section to the guide section, the force can be transmitted along a predetermined path to the edge of the top-penetrating piece, forming an effective guiding effect. The guide section guides the force to concentrate on the connection between the top-penetrating piece and the mounting ring, ultimately making it easier to penetrate the top-penetrating piece.

[0019] (3) A semicircular protrusion is provided at the center of the upper surface of the top-penetrating piece, and the semicircular protrusion surrounds the outside of the positioning section. With this arrangement, the semicircular protrusion can guide the initial contact of the smart column above the top-penetrating piece, so that the smart column first contacts the semicircular area of the protrusion before entering the positioning section, thereby ensuring that the smart column is more stable when entering the positioning section. In addition, the semicircular design of the protrusion surrounds the outside of the positioning section, forming a blocking area. This design ensures that the smart column will not slide toward other areas away from the guide section when inside the positioning section. Through this structure, the penetration force can be more concentratedly transferred along the positioning section to the guide section, avoiding the dispersion of force to other positions of the top-penetrating piece, which not only improves the accuracy of the penetration, but also significantly improves the reliability of the penetration.

[0020] (4) A connecting piece is provided, the connecting piece is fixedly connected to the lower surface of the top-penetrating piece, and one end of the connecting piece is fixedly connected to the end of the mounting ring away from the guide section. Thus, when the side of the top-penetrating piece close to the groove is pushed open, the top-penetrating piece and the connecting piece are flipped downward relative to the mounting ring. At this time, the top-penetrating piece is connected to the mounting ring through the connecting piece, which can avoid the risk of the top-penetrating piece falling after being completely torn.

[0030] The following will be combined with 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, not all of the embodiments. 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.

[0031] like Figure 1 As shown, combined Figure 2-6 The embodiment of the utility model discloses an easy-to-break top-penetrating cover, including a cover body 1 and a top-penetrating piece 2. The cover body 1 is used to connect with the barrel mouth of bottled water. The center of the top surface of the cover body 1 is recessed downward to form a cylindrical mounting ring 11. The end of the mounting ring 11 is open. Therefore, the cylindrical mounting ring 11 is used for engaging and limiting when docking with the water dispenser. At the same time, the cylindrical mounting ring 11 is used to provide a mounting base for the top-penetrating piece 2.

[0032] The top-penetrating piece 2 is sealed and connected to the end of the mounting ring 11. A tearing portion 21 is formed between the top-penetrating piece 2 and the inner wall of the mounting ring 11. The tearing portion 21 allows the top-penetrating piece 2 to tear when subjected to external force, thereby forming an opening between the top-penetrating piece 2 and the mounting ring 11, making it convenient for water in the bottled water to flow into the water dispenser through the above-mentioned opening.

[0033] In the prior art, when the user installs bottled water on the water dispenser, the smart column of the water dispenser extends into the mounting ring 11 and contacts the center of the top-penetrating piece 2. At this stage, half of the tear portion 21 between the top-penetrating piece 2 and the mounting ring 11 has a uniform thickness, which causes the force applied by the smart column to the center of the top-penetrating piece 2 to be dispersed around the top-penetrating piece 2, and a larger penetration force is required to break the top-penetrating piece 2.

[0034] In order to solve the above problems, the solution adopted in this embodiment is to provide a groove 22 on the upper surface of the top-penetrating piece 2. The groove 22 extends from the center of the top-penetrating piece 2 to the edge of the top-penetrating piece 2. The bottom surface of the groove 22 is an inclined structure, and the height of the bottom surface of the groove 22 gradually decreases from the center of the top-penetrating piece 2 to the edge of the groove 22.

[0035] With this arrangement, when the user assembles the bottled water on the water dispenser, the smart column on the water dispenser extends into the mounting ring 11 and contacts the middle position of the top-penetrating piece 2. At this time, the smart column just contacts the bottom surface of the groove 22 at one end of the center of the top-penetrating piece 2. Since the bottom surface of the groove 22 is an inclined structure, when the smart column applies a vertical upward opening force on the top-penetrating piece 2, it will slide from the center of the top-penetrating piece 2 to the edge along the inclined direction of the groove 22, so that the penetration force of the smart column is concentrated in the edge area of the groove 22 close to the top-penetrating piece 2, and the edge of the top-penetrating piece 2 is subjected to higher local pressure, making the edge of the top-penetrating piece 2 easier to tear and break quickly, reducing the required penetration force.

[0036] As some preferred embodiments, the groove 22 includes a positioning section 221 and a guide section 222. The positioning section 221 is located at the center of the top-penetrating piece 2. The positioning section 221 is semicircular in shape. This structural arrangement enables the smart column of the water dispenser to accurately act on the center position of the positioning section 221 when it first contacts the top-penetrating piece 2. The guide section 222 is in the shape of a strip, one end of the guide section 222 is tangentially connected to the positioning section 221, and the other end is connected to the edge of the top-penetrating piece 2. The strip-shaped design of the guide section 222 ensures that when the top-penetrating force is transferred from the positioning section 221 to the guide section 222, the force can be transmitted along a predetermined path to the edge of the top-penetrating piece 2, forming an effective guiding effect. The guide section 222 guides the force to concentrate on the connection between the top-penetrating piece 2 and the mounting ring 11, ultimately making the top-penetrating piece 2 easier to penetrate.

[0037] Preferably, the diameter of the positioning section 221 is greater than or equal to the diameter of the smart column. Thus, when the smart column contacts the positioning section 221, it can accurately enter the semicircular area of the positioning section 221 without sliding or misalignment.

[0038] As some preferred embodiments, a semicircular protrusion 23 is provided at the center of the upper surface of the top-penetrating piece 2, and the semicircular protrusion 23 surrounds the outside of the positioning section 221. With this arrangement, the semicircular protrusion 23 can guide the initial contact of the smart column above the top-penetrating piece 2, so that the smart column first contacts the raised semicircular area before entering the positioning section 221, thereby ensuring that the smart column is more stable when entering the positioning section 221. In addition, the raised semicircular design surrounds the outside of the positioning section 221, forming a blocking area. This design ensures that the smart column will not slide toward other areas away from the guide section 222 when inside the positioning section 221. Through this structure, the penetration force can be more concentratedly transferred along the positioning section 221 to the guide section 222, avoiding the dispersion of force to other positions of the top-penetrating piece 2. This not only improves the accuracy of the penetration, but also significantly improves the reliability of the penetration.

[0039] In some preferred embodiments, the vertical height from the lowest end of the bottom surface of the groove 22 to the upper surface of the penetration piece 2 is less than or equal to half the thickness of the penetration piece 2. This technical solution improves the transmission efficiency and concentration of the penetration force while maintaining the strength of the penetration piece 2. This design not only enhances the efficiency and reliability of penetration, but also ensures the structural integrity and stability of the penetration piece 2 during use.

[0040] Some preferred embodiments further include a connecting piece 3, which is located on the lower surface of the top-penetrating piece 2 and corresponds to the groove 22 in a vertical manner. The connecting piece 3 is fixedly connected to the lower surface of the top-penetrating piece 2, and one end of the connecting piece 3 is fixedly connected to the end of the mounting ring 11 away from the guide section 222. With this structural arrangement, since the edge of the top-penetrating piece 2 away from the guide section 222 and the mounting ring 11 are fixedly connected via the connecting piece 3, when the side of the top-penetrating piece 2 close to the groove 22 is pushed open, the top-penetrating piece 2 and the connecting piece 3 are flipped downward relative to the mounting ring 11. At this time, the top-penetrating piece 2 is connected to the mounting ring 11 via the connecting piece 3, which can avoid the risk of the top-penetrating piece 2 falling off after being completely torn.

[0041] Preferably, the thickness of the tear portion 21 is half the thickness of the top-penetrating sheet 2 , which can ensure the structural strength of the top-penetrating sheet 2 while ensuring that the top-penetrating sheet 2 can be quickly torn at the tear portion 21 when the edge is stressed.

[0042] Preferably, a threaded portion 12 is provided on the inner side surface of the cover body 1 to facilitate threaded connection with the bottle mouth of bottled water.

[0043] Preferably, the inner top surface of the cover body 1 is convex downward to form an annular sealing portion 13, which is located on the outside of the mounting ring 11 to ensure that the cover body 1 and the bottle mouth of the bottled water can be sealed through the annular sealing portion 13 after being connected.

[0044] The outer side surface of the cover body 1 is provided with anti-slip grooves 14, which can increase the degree of friction between the outer side surface of the cover body 1 and the user's hand.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
