Description

A kind of seal bottle cap of flexible contact type
Technical field
The utility model relates to the packing technique of cap-rotating type container, particularly a kind of seal bottle cap of flexible contact type.
Background technology
At present, the Bottle cap structure of cap-rotating type is widely used in the Packaging Bottle of all kinds of article of daily life, as various beverage bottles, medicine bottle, bottle, apothecary jar etc.Traditional Bottle cap structure as shown in Figure 1 or 2, the first seal ring 1-1 and bottleneck 2 top close contacts by lid 1 inner top form sealing, there is following defect in this structure: sealing range is little, safe not, health, when people drink or dumping bottle in during article, in people's mouth or bottle, liquid can contact with the linkage section between false proof ring 1-3 with top conventionally, and this linkage section is outside sealing range, do not have sealed protection, therefore producing, transportation, in the process of stock or sale likely by airborne dust, objectionable impurities in germ or refrigeration liquid is polluted, thereby eater's health is formed to potential danger.
In order to overcome above-mentioned defect, at present also have by set up a seal structures in the joint of lid bottom and bottleneck, its structure has two kinds:
(1) seal ring is set up in lid bottom, joins, thereby realize sealing by seal ring bottom and the boss end face of bottleneck periphery.Yet, in actual applications, the often out of reach designing requirement of precision while producing due to lid, and the sealing of two places is positiver sealing, so being positioned at two place's seal rings of lid top, bottom cannot realize sealing (seal ring and the bottleneck that are top are just adjacent to while joining, and still may have gap between the seal ring of bottom and boss simultaneously; Or the seal ring of bottom and boss be just adjacent to while being connected, between the seal ring at top and bottleneck, also still may there is gap), therefore, the bottle cap of this structure in fact also can only guarantee one sealing, its sealing effectiveness is unsatisfactory.
(2) seal ring is set up in lid bottom, and seal ring is located at the boss periphery of bottle cap periphery, joins, thereby realize sealing by level outside seal ring inner side and boss.Yet in actual applications, because seal ring is located at boss periphery, when user tightens bottle cap, its operating difficulties, is used inconvenience; In addition, the lid of this structure die sinking difficulty in actual production is very large, is difficult to realize produce in enormous quantities.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of seal bottle cap of simple in structure, the easy to use and good flexible contact type of sealing effectiveness is provided.
The technical solution of the utility model is: a kind of seal bottle cap of flexible contact type, comprise the bottleneck and the lid that are threaded, the joint of bottleneck top and lid end face is provided with the first seal ring, the outer peripheral face of bottleneck bottom is provided with bulge loop, bulge loop is positioned at false proof ring top, week is provided with the second seal ring with the joint of bulge loop in lid, and the second seal ring is positioned at bulge loop top, and the second seal ring and bulge loop flexibly connect.
The outer peripheral face of described bulge loop is with dip plane, and the second seal ring is plastic circle ring, and after lid and bottleneck are tightened and be connected, the medial surface of the second seal ring is closely attached on the dip plane of bulge loop.
As a kind of preferred version, the axial cross section of described the second seal ring is del, specifically can be V-arrangement or serration etc.
As another kind of preferred version, the axial cross section of described the second seal ring is wide at the top and narrow at the bottom trapezoidal.
Due to the second seal ring and lid one-shot forming, general material is also identical, so its quality is still with certain rigidity, the second seal ring is made as to trapezoidal or triangle wide at the top and narrow at the bottom, when being more conducive to lid and being connected with bottleneck, the second seal ring easily produces distortion and is closely connected with boss, and its sealing property can be ensured preferably.
Described lid and the second seal ring are integral type structure, and the top of the second seal ring is fixedly connected with lid, and medial surface and the bulge loop of the second seal ring join.
Described bulge loop and bottleneck are integral type structure.
When the seal bottle cap of this flexible contact type is used, its principle is: in the process of bottle cap being tightened downwards user, the second seal ring bottom first contacts the dip plane of bulge loop, when bottle cap continues to tighten downwards, the second seal ring produces distortion, and the medial surface of the second seal ring contacts with the dip plane of boss; In the process that area of contact between the medial surface of the second seal ring and the dip plane of boss increases gradually, the first seal ring also progresses into bottleneck and joins with bottleneck top; When lid is tightened completely, the first seal ring and the second seal ring are realized sealing simultaneously.
The utility model, with respect to prior art, has following beneficial effect:
The seal bottle cap of this flexible contact type can be realized the two seals of bottleneck preferably, linkage section between bottleneck top and false proof ring is realized to effective sealing, can effectively prevent the contaminated phenomenon of this linkage section, greatly improve safety and the wholesomeness of bottle cap, ensure better consumer health.
The seal bottle cap of this flexible contact type is simple in structure, easy to use, the first seal ring, the second seal ring can with lid one-shot forming, its manufacture craft is also simple, do not need existing filling production lines significantly to improve and can realize, its cost of manufacture is also lower, good market prospect.
The field of application of the seal bottle cap of this flexible contact type is wider, can be widely used in the Packaging Bottle of all kinds of cap-rotating types, as various beverage bottles, medicine bottle, bottle, apothecary jar etc.
