The specific embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model is further introduced and explanation, but be not limited to this.
Extremely shown in Figure 11 as Fig. 1, the specific embodiment of the utility model anti-loosing type refluence reclaiming type Bottle cap structure and liquid packaging bottle.Liquid packaging bottle comprises the body 10 that is provided with bottleneck 11, and bottle mouth position is provided with anti-loosing type refluence reclaiming type Bottle cap structure 20.
Anti-loosing type refluence reclaiming type Bottle cap structure 20 comprises the lower cover 21 that connects with body 10, and screws the loam cake 22 that connects with lower cover 21; The inboard of lower cover 21 is provided with the backflow wall 211 that extends to the center, extends upward in the middle of the backflow wall 211 to be provided with the prominent ring 212 of water conservancy diversion, and backflow wall 211 is ramp structure, and gradient is 5~10 degree, and the lowest part in the inclined-plane is provided with refluxing opening 213; The prominent ring 212 of water conservancy diversion is provided with the peristome 216 that links with refluxing opening 213.Lower cover 21 is provided with the negative thread 214 that is positioned at backflow wall 211 tops, and the lower end of loam cake 22 is provided with outside thread 221; The below of negative thread 214 is provided with sealing inner conical surface 215, and the lower end edge of loam cake 22 is provided with and seals the outer lug portion 222 that inner conical surface 215 pressure contact.Form the first order hermetically-sealed construction of loam cake and lower cover with this.In the present embodiment, sealing inner conical surface 215 is yearned for backflow wall center position from the below of negative thread and has been done some extensions, make the distance of first order hermetically-sealed construction and internal and external threads increase, to reduce the interference of the two, be particularly advantageous in the product injection molded of loam cake and lower cover.
Lower cover 21 is provided with the sealing inwall 217 greater than negative thread 214 diameters in the top of negative thread 214; Loam cake 22 is provided with the sealing bulge loop 223 greater than outside thread 221 external diameters in the top of outside thread 221, sealing bulge loop 223 contacts for sealing pressure with sealing inwall 217 when screwing state.Form the second stage hermetically-sealed construction of loam cake and lower cover with this.
Loam cake 22 is provided with the convex shoulder 224 that is positioned at sealing bulge loop 223 tops, and the lower surface of convex shoulder 224 contacts for sealing pressure with the upper end edge 218 of lower cover 21 when screwing state.Form the third stage hermetically-sealed construction of loam cake and lower cover with this.For the ease of the operation that screws of loam cake, on the cylindrical of loam cake, also be provided with anti-skidding striped 225.
The upper end edge inboard of bottleneck 11 is provided with internal projection portion 12, and backflow wall 211 comprises and water conservancy diversion prominent ring 212 bottoms that connect 2111 and the cylindrical portion 2112 that connects with negative thread 214 belows, the sealing cylindrical portion that cylindrical portion 2112 formations contact with internal projection portion 12 pressure.Constitute the hermetically-sealed construction of lower cover and body with this.For the ease of the realization of processing and sealing effectiveness, cylindrical portion 2112 can adopt certain taper.
Lower cover 21 is located at the following negative thread 219 that connects that is positioned at backflow wall below; Bottle mouth position is provided with down and connects outside thread 13; The below that connects outside thread 13 down is provided with block 14 under the bottleneck, and the initial end 2190 that connects negative thread 219 down only is butted on block 14 under the bottleneck when screwing state.The bottleneck end of body 10 is along being provided with bottleneck block 15, and lower cover 21 is provided with and is positioned at the internal stop 2191 that connects negative thread 219 tops down, and internal stop 2191 only is butted on bottleneck block 15 when screwing state.Because what the prominent ring of the water conservancy diversion of lower cover adopted is the structure with peristome, so the setting angle of lower cover is requirement, so that user's pouring liquid, therefore, two block structures have realized the accurate location of the setting angle of lower cover.
The cylindrical of lower cover 21 is provided be used to the reference protrusion portion 210 that screws the location reference.When lower cover and body are installed, be used for prompting and be in place.
The inboard, lower end of lower cover 21 is provided with several and prevents the gear piece 2100 that reverses; Bottleneck 11 is provided with the tooth portion 16 of several anti-reversings in the below that connects outside thread 13 down.So that lower cover and body can't reverse after installing, tear open not open, perhaps need to adopt by force means to remove; Thereby, reduce loam cake and lower cover and screw when operating, the assembly relation of lower cover and body is impacted.
In other embodiment, the prominent ring of water conservancy diversion also can adopt tubular construction, is not provided with peristome, and wherein tubular construction can also adopt certain tapering.In other embodiment, can increase scale marker at the inner chamber of loam cake.For the ease of the observation to scale marker, loam cake preferentially adopts material transparent to make.In other embodiment, the reference protrusion portion on the cylindrical of lower cover can make into reference to inner fovea part.
In sum, the utility model anti-loosing type refluence reclaiming type bottle cap and liquid packaging bottle have adopted gear piece and the tooth portion of anti-reversing, increase the screw thread constant intensity of lower cover and body, the thread connection to lower cover and body in the time of can preventing the rotation of loam cake and lower cover impacts.And below the lower cover negative thread, be provided with the sealing inner conical surface, lower end edge at loam cake is provided with an outer lug portion, and when loam cake and lower cover screwed state, outer lug portion pressure was contacted with the sealing inner conical surface, outer lug portion produces local deformation, forms sealed attachment limit closely.Body and lower cover have also adopted the hermetically-sealed construction of internal projection portion with sealing cylindrical portion.Owing to adopted integrally formed outer lug portion, internal projection portion, make to the utlity model has good seal performance, characteristics that productive costs is low, and the sealed attachment limit is positioned at the below of screw thread, do not have liquid and flow into the screw thread place, prevent that liquid from flowing to the screw thread place, more cleans during use.The utility model liquid packaging bottle also further is provided with the block structure at the upper and lower that connects screw thread, when making the assembling of lower cover and body, can locate rapidly and accurately.
Above-mentionedly only further specify technology contents of the present utility model with embodiment; so that the reader is more readily understood; but do not represent embodiment of the present utility model and only limit to this, any technology of doing according to the utility model is extended or recreation, all is subjected to protection of the present utility model.Protection domain of the present utility model is as the criterion with claims.
