Detailed Description
The following description of the embodiments of the present utility model will clearly and fully describe the technical aspects of the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, are intended to fall within the scope of the present utility model.
Referring to fig. 1 and fig. 2, the utility model discloses an anti-deformation beverage bottle cap, which comprises a lower cap body 2, wherein the lower cap body 2 is made of PE (polyethylene), and concretely can be made of HDPE (high-density polyethylene) or LDPE (low-density polyethylene). The lower cover body 2 comprises a cover body 21 for being connected with the bottle mouth of the beverage bottle, an inner plug structure 22 is arranged on the inner bottom surface of the cover body 21, and the inner plug structure 22 is used for being connected with the bottle mouth in a sealing way. In this embodiment, the lower cover 2 is preferably made of HDPE, which has high flexibility, and is formed to be tightly attached to the inner wall of the bottle mouth to perform a main sealing function.
Since the thermal deformation temperature of the PE cover body 21 is relatively low, extrusion deformation is easy to occur at high temperature, and the deformation of the inner plug structure 22 can cause gas-liquid leakage; in particular, carbonated beverages contain pressure, coupled with shaking during transportation, squeezing, and high temperature activation of the separation of the internal carbon dioxide from the liquid, causing upward deformation and outward displacement of the inner plug structure 22, which results in failure of the sealed connection between the inner plug structure 22 and the bottle neck, and thus leakage of the liquid or gas.
For this reason, the structure of the present beverage bottle cap is improved, and in particular, the beverage bottle cap of this embodiment further provides an upper layer cap body 1, the material of the upper layer cap body 1 is PP (polypropylene), and the upper layer cap body 1 is coated on the outer surface of the cap body 21 and is integrally injection molded with the cap body 21.
By adopting the technical scheme, the high-hardness high-temperature-resistant polypropylene PP with high-density polyethylene HDPE with high flexibility is used as a cover material combination, the high-hardness high-plasticity high-temperature-resistant polypropylene PP with high-temperature-resistant high-plasticity high-temperature-resistant polypropylene HDPE is used as an upper cover 1 of the anti-deformation beverage bottle cover, and the upper cover 1 is coated on a lower cover 2 made of the HDPE material to form a protective layer. When the inner plug structure 22 in the lower cover body 2 is extruded by external force, is in high-temperature environment and expands in the beverage bottle, the inner plug structure 22 is protected by the PP material with high hardness of the upper cover body 1, so that the inner plug structure 22 is prevented from deforming upwards, the deformation resistance of the beverage bottle cover is improved, and the sealing performance of the bottle cover and the bottle mouth is further improved.
In order to make the structural strength of the upper cover 1 and the lower cover 2 stronger after the integral injection molding, the embodiment adopts the following scheme, specifically, the lower peripheral wall of the cover body 21 is provided with a flange 211 with an annular structure, the top surface of the flange 211 is provided with an annular groove 2111, the bottom end surface of the upper cover 1 abuts against the top surface of the flange 211, and the bottom end surface of the upper cover 1 is further provided with an annular convex wall 11 matched with the annular groove 2111.
By adopting the technical scheme, after injection molding is completed on the lower cover body 2, injection molding is performed again, the upper cover body 1 can be coated on the surface of the lower cover body 2, and meanwhile, the annular convex wall 11 at the bottom of the molded upper cover body 1 is embedded in the annular groove 2111, so that two materials of the lower cover body 2 and the upper cover body 1 are firmly adhered after fusion molding.
It should be noted that, in this embodiment, the combination of the lower cover 2 and the upper cover 1 forms the deformation-proof bottle cap by a two-component injection molding process, wherein the two-component injection molding process belongs to the prior art.
In order to achieve the sealing of the inside plug structure 22 and the finish, the present embodiment illustrates some specific configurations of the inside plug structure 22, as shown in FIGS. 3-5.
The inner plug structure 22 includes a first inner plug ring piece 221, where the first inner plug ring piece 221 is coaxially and fixedly disposed on the inner top surface of the cap body 21 and is used for being inserted into the inner wall of the bottle mouth, and the outer diameter of the first inner plug ring piece 221 is in interference fit with the inner diameter of the bottle mouth. Specifically, the outer diameter of the first inner plug ring piece 221 is 0.2mm-1mm larger than the inner diameter of the bottle mouth. Because the lower cover body 2 is made of HDPE material with a soft structure, the first inner plug ring piece 221 has stronger elasticity and can be plastically deformed when being inserted into the inner wall of the bottle mouth, thereby being tightly attached to the inner wall of the bottle mouth to realize interference fit with the inner wall of the bottle mouth.
In addition, since the upper cover 1 is made of PP material with high hardness, this can protect the first inner ring plug 221, and when the beverage bottle is axially pressed, the upper cover 1 can protect the first inner ring plug 221, so as to avoid or reduce the axial movement of the first inner ring plug 221, thereby realizing reliable sealing with the bottle mouth.
As some preferred embodiments, the outer wall of the first inner plug ring piece 221 has a certain taper, the outer diameter of the lower end of the first inner plug ring piece 221 is larger than the outer diameter of the upper end of the first inner plug ring piece 221, and therefore, the first inner plug ring piece 221 is arranged in an enlarged-mouth taper shape, so that the interference fit strength of the first inner plug ring piece 221 and the inner wall of a bottle opening can be improved, and the sealing performance with the bottle opening is further improved.
On the basis of the above technical solution, since the first inner ring plug 221 is tapered with an enlarged opening, this may reduce the strength of interference fit between the upper end of the outer wall of the first inner ring plug 221 and the bottle mouth, and thus, in this embodiment, at least two sealing protrusions 2211 with annular structures are disposed on the outer wall of the first inner ring plug 221 along the axial direction thereof. In this way, in the process of inserting the first inner plug ring piece 221 into the bottle mouth, the sealing protrusion 2211 passes through the bottle mouth from bottom to top and is attached to the inner wall of the bottle mouth, so that each sealing protrusion 2211 independently supports sealing work at each section of the inner wall of the bottle mouth, multiple sealing connections are formed between the first inner plug ring piece 221 and the inner wall of the bottle mouth in the axial direction, and meanwhile, when the sealing protrusion 2211 is radially extruded, stronger elastic deformation can be applied, the interference fit capability between the sealing protrusion 2211 and the bottle mouth is further improved, and leakage is avoided to the greatest extent.
In order to further improve the tightness, the inner plug structure 22 of the present embodiment further includes a second inner plug ring piece 222, where the second inner plug ring piece 222 is coaxially and fixedly disposed on the inner top surface of the cap body 21 and is located on the outer peripheral side of the first inner plug ring piece 221, and is used for being sleeved on the outer wall of the bottle opening, and the inner diameter of the second inner plug ring piece 222 is in interference fit with the outer diameter of the bottle opening.
By adopting the technical scheme, the second inner plug ring piece 222 radially supports the outer wall of the bottle mouth, so that the directions of the second inner plug ring piece 222 and the first inner plug ring piece 221 radially support the bottle mouth are opposite, and the bottle mouth is firmly clamped in the first inner plug ring piece 221 and the second inner plug ring piece 222, so that the bottle mouth is prevented from being displaced in the radial direction, and the sealing reliability of the inner plug structure 22 to the bottle mouth is improved.
On the basis of the above technical solution, the inner plug structure 22 further includes a sealing ring 223, the sealing ring 223 is coaxially and fixedly disposed on the inner top surface of the cap body 21, and is located between the first inner plug ring piece 221 and the second inner plug ring piece 222, and the sealing ring 223 is used for performing abutting sealing with the end surface of the bottle mouth. Therefore, when the bottle mouth is connected to the inner wall of the cover body 21 in a threaded screwing mode, the end part of the bottle mouth can be abutted against the sealing ring 223, and plastic deformation can occur due to the flexibility of the sealing ring 223, so that the sealing ring 223 can squeeze and seal the end part of the bottle mouth, and the sealing ring 223 can exert the second sealing line-proof performance on the premise that the first inner plug ring piece 221 exerts the first sealing line-proof performance.
As some other embodiments, the top surface of the cover body 21 is provided with a modeling protrusion 212, and the upper cover body 1 is provided with a hollowed-out hole 12 matched with the modeling protrusion 212. From this setting, through the two-component injection molding, can be with bottle lid surface through injection molding process shaping various molding figures, LOGO, can select different colour plastic materials through upper cover 1 and lower cover 2 to realize making fashioned beverage bottle lid vivid color, reinforcing consumer's visual experience.
Preferably, the cover body 21 is further provided with an anti-theft ring 23 on the bottom end surface. The main function is to ensure that the anti-theft ring 23 remains on the bottle mouth when the bottle cap is opened, so as to protect the content in the beverage bottle from being damaged by people.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
