Description

Technical Field

[0001] This utility model specifically relates to a bottle cap with a protective cover that can store material. Background Technology

[0002] Most beverage bottles on the market have caps, allowing consumers to simply unscrew the cap and drink. However, some beverages require additional ingredients, leading to the development of detachable caps. Detachable caps typically have the ingredient pre-placed inside the cap's cavity, allowing consumers to mix the ingredient with the beverage after opening the cap. For a specific structure, refer to the inventor's previous patent application, CN202322835761.6, entitled "A Convenient Unsealing Structure for Detachable Caps." Because traditional storage-type caps are complex and inconvenient to operate, the inventor previously developed a press-type storage cap. However, this type of cap has an exposed pressing structure, making it prone to accidental operation and causing inconvenience in use and transportation.

[0003] This utility model was developed precisely because of the aforementioned shortcomings. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a storage-type bottle cap with a protective cover to prevent misoperation.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a storage-type bottle cap with a protective cover, comprising a bottle cap base, a sealing member, and a protective cover; the bottle cap base has a storage cavity with an open top, the bottom of which is formed by a thin-walled base plate, and the thin-walled base plate has at least one groove; the sealing member has a connecting ring around the opening of the storage cavity and tightly connected to the bottle cap base, the sealing member closes the opening of the storage cavity and thus forms a storage space for filling materials with the inner wall of the storage cavity; the sealing member has a deformable pressing part in the middle for manual pressing, the pressing part is connected to a pressing post that can press against the thin-walled base plate when pressed down, and when the pressing post presses against the thin-walled base plate, the groove on the thin-walled base plate is torn; the protective cover is fitted onto the bottle cap base from top to bottom and covers the sealing member.

[0007] As described above, the storage-type bottle cap with a safety cap has an outer ring cylinder on the outside of the cap seat, and the top of the protective cap is fitted onto the outer ring cylinder.

[0008] As described above, the storage bottle cap with a safety cap has an upward-protruding pressing part for manual pressing, and the top of the protective cap has a cover part that is correspondingly provided to the pressing part and arched upward.

[0009] As described above, the storage-type bottle cap with a safety cap has several vertically arranged locking grooves on the outer side wall of the outer ring cylinder, and vertically arranged locking ribs on the inner side wall of the protective cap that can be locked into the locking grooves.

[0010] As described above, the storage cap with a safety cap has vertical stripes on the outer wall of the protective cap to allow for hand operation and increase friction.

[0011] As described above, in the storage-type bottle cap with a safety cap, the bottle cap seat has an annular mounting surface around the opening of the storage compartment, the connecting ring matches the shape of the annular mounting surface, and the connecting ring is connected to the annular mounting surface by bonding or hot pressing.

[0012] As described above, the storage cap with a safety cap is a one-piece structure made of plastic or silicone.

[0013] As described above, in the storage-type bottle cap with a safety cap, the thin-walled bottom plate is set as the pressure point at the position corresponding to the top pressure column. The bottom of the hopper has at least three bending grooves. The bending grooves are connected end to end to form a polygonal structure centered on the pressure point. The number of cutting grooves corresponds to the number of bending grooves. One end of the cutting groove is connected to the end of the bending groove, and the other end of the cutting groove extends toward the pressure point and is connected to each other around the pressure point.

[0014] As described above, in the storage-type bottle cap with a safety cap, the cross-section of the cut groove is an isosceles trapezoid or an isosceles triangle that gradually decreases in size from bottom to top.

[0015] As described above, in the storage-type bottle cap with a safety cap, the cross-section of the bending groove is trapezoidal, and the slope of the waistline near the pressure point is smaller than that of the waistline away from the pressure point.

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

[0017] 1. Prevents accidental release and enhances safety: By adding a protective cover, the problem of premature release of materials due to accidental operation during storage, transportation, or sales is effectively avoided. The protective cover design not only ensures the integrity of the product but also enhances the user's sense of security.

[0018] 2. Simple operation: Users can easily activate the material release mechanism by simply removing the protective cover and pressing the pressing part. The cover design allows users to assist in the pressing operation by flipping the protective cover, further improving the convenience and comfort of operation.

[0019] 3. Optimize material release effect: The bottom of the thin-walled base plate is equipped with bending grooves and cutting grooves to ensure that the top pressure column can tear the thin-walled base plate evenly when it presses down, so that the material is released in a regular and uniform manner, which improves the discharge speed and efficiency.

[0025] The utility model will be further described below with reference to the accompanying drawings:

[0026] The orientations described in this utility model specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the utility model and are not a limitation on its implementation.

[0027] This utility model introduces a receptacle cap with a protective cover for connecting and sealing beverage bottles. For example... Figures 1 to 4 As shown, the bottle cap structure includes a cap seat 1, a sealing member 2, and a protective cap 3. The cap seat 1 has a threaded structure for connecting to the top of the bottle body. The cap seat 1 has a material storage cavity 10 with an open top, and its bottom is formed by a thin-walled base plate 11. The thin-walled base plate 11 has at least one cutting groove 12, which can be formed by cutting or by creating a material thinning area during injection molding.

[0028] The cap 2 has a connecting ring 21 around the edge of the storage cavity 10 and tightly connected to the cap seat 1. The connecting ring 21 is fixed to the cap seat 1 by a plastic hot-melt process, so that the cap 2 and the cap seat 1 form a closed storage space for storing materials (such as tea powder, sugar powder, seasonings, etc.). The cap 2 has a pressing part 22 in the middle, which is connected to a top pressing column 23. When the pressing part 22 is pressed, the top pressing column 23 will break through the groove 12 on the thin-walled bottom plate 11, allowing the material stored in the storage cavity 10 to flow into the beverage bottle for mixing.

[0029] Preferably, the protective cap 3 is fitted over the bottle cap holder 1 from above and covers the sealing element 2 to prevent premature release of material due to misoperation during storage, transportation, or sales. To achieve this function, an outer ring cylinder 13 is provided on the outside of the bottle cap holder 1, and the top of the protective cap 3 is fitted onto the outer ring cylinder 13.

[0030] In detail, the bottle cap holder 1 has an annular mounting surface 15 around the opening of the storage compartment. The connecting ring 21 matches the shape of the annular mounting surface 15, and the connecting ring 21 is tightly connected to the annular mounting surface 15 by plastic hot pressing or hot melting process. Of course, it can also be connected by adhesive bonding or other methods.

[0031] In a preferred embodiment, the pressing part 22 protrudes upward for pressing by hand. The top of the protective cover 3 is provided with a cover part 31 that is corresponding to the pressing part 22 and arches upward. This not only protects the pressing part 22 from being pressed incorrectly, but also allows the protective cover 3 to be removed and flipped over during use, with the cover part 31 assisting in the pressing operation, increasing the force-bearing space and facilitating user operation.

[0032] The outer wall of the outer ring cylinder 13 is provided with several vertically arranged locking grooves 14, and the inner wall of the protective cap 3 is provided with vertically arranged locking ribs 32 that can be locked into the locking grooves 14. In this way, when the user needs to unscrew the bottle cap, he only needs to unscrew the protective cap 3, which further increases the convenience of operation. In order to facilitate the user to unscrew the protective cap 3, the outer wall of the protective cap 3 is provided with vertical stripes 33 for hand operation and to increase friction.

[0033] like Figure 5As shown, the thin-walled bottom plate 11 is designated as the pressure point P at the position corresponding to the top pressure column 23. At least three bending grooves 16 are formed at the bottom of the hopper. These bending grooves are connected end-to-end to form a polygonal structure centered on the pressure point, i.e., an equilateral triangle structure. The number of cutting grooves 12 corresponds to the number of bending grooves 16. One end of each cutting groove 12 connects to the endpoint of the bending groove 16, and the other end extends towards the pressure point and connects with each other around the pressure point. The bottom of the thin-walled bottom plate 11 also has cutting grooves 12 corresponding to the number of bending grooves 16. One end of each cutting groove 12 connects to the endpoint of the bending groove 16, and the other end extends towards the pressure point P and connects with each other around the pressure point P. The thin-walled bottom plate 11 has an arc-shaped tear groove 17 surrounding the pressure point P. The cutting grooves 12 connect with the arc-shaped tear groove 17, thus making each cutting groove 12 interconnected.

[0034] When the user presses down on the pressing part 22, the top pressure column 23 presses against the bottom of the thin-walled base plate 11, causing the bottom of the thin-walled base plate 11 to deform under stress. After the bottom of the thin-walled base plate 11 deforms, stress concentration first occurs at the position of the cut groove 12, which then tears the bottom of the thin-walled base plate 11 along the length of the cut groove 12. Since the bending groove 16 forms a polygonal structure and surrounds the pressure point P, when the pressure point P is subjected to downward thrust, the tear area A surrounded by the bending groove 16 is more easily deformed, while the material outside the tear area A is less affected. Meanwhile, since the cutting groove 12 extends from the endpoints of this polygon towards the center, it divides the fracture area A into three evenly distributed fragment areas A1. When the top pressure column 23 presses down, it can first generate stress concentration at the position near the center of the cutting groove 12, so that the cutting groove 12 is gradually torn from the center to the surrounding area, and each fragment area A1 is separated. This avoids problems such as the top pressure column 23 having large resistance and tilting due to uneven resistance around the perimeter when the top pressure column 23 presses down. It also makes the bottom of the thin-walled bottom plate 11 crack evenly from the pressure point P along the cutting groove 12 to the surrounding area. The cracked opening is regular and uniform, ensuring rapid and uniform material discharge.

[0035] Preferably, the pressure column 23 is composed of six vertically arranged support plates evenly distributed along the circumference, making the outer contour of the entire pressure column 23 a hexagonal column. In the design, considering optimization and practicality, we chose to design the pressure column 23 as being composed of six vertically arranged support plates. These support plates are evenly distributed along the circumference, with an included angle of 60° between adjacent support plates. Thus, the outer contour of the entire pressure column 23 presents a regular hexagonal column shape. This unique hexagonal structure design has significant advantages. From a mechanical perspective, compared to other shapes, the hexagonal structure distributes force more evenly when subjected to external forces, with each side and corner working together to bear the force, effectively improving the structural strength of the pressure column 23, enabling it to withstand greater pressure without easily deforming or being damaged. Simultaneously, this structure greatly facilitates the installation of the cover 2 in practical applications. Due to the hexagonal structure of the pressure column 23, regardless of the angle to which the cover 2 rotates, the pressure column 23 can stably press against the three fragmentation zones A1. This means that the installation angle of the cover 2 is no longer strictly limited, and there is no need to repeatedly adjust the angle to find a suitable top pressure position during the installation process, which greatly improves the installation efficiency and convenience, and reduces the installation difficulty and cost.

[0036] The cut groove 12 has a cross-section that gradually decreases in size from bottom to top, resembling an isosceles trapezoid or an isosceles triangle. The bending groove 16 has a trapezoidal cross-section, and the slope of the waistline near the pressure point is smaller than that of the waistline farther from the pressure point. Figure 2 As shown, the waistline 161 on the side closer to the pressure point P and the waistline 162 on the side farther from the pressure point P of the bending groove 16 section are shown. It can be seen that the slope of the waistline 161 is gentler, so that when the tearable groove cracks, the material in each fragment partition A1 can deform and bend at the bending groove 16.

[0037] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
