Abstract
The utility model relates to a kind of seal bottle caps.Seal bottle cap described in the utility model, comprising: lower screw thread is arranged in lower cover and upper cover, the lower cover lower inside, and upper screw thread is arranged in the lower cover upper outside, and through-hole is arranged in the lower cover center upper portion；Screw thread is arranged in upper screw thread described in the upper cover fit inside.Seal bottle cap described in the utility model, when taking out article in bottle, it is only necessary to by opening upper cover, so that the contact area of article and air in bottle is reduced, to extend the article holding time.
Description
Technical field
The utility model relates to a kind of bottle caps, more particularly to a kind of seal bottle cap.
Background technique
Bottle cap is the place that food is contacted with product at first with the important ring of drink packing and consumer, and bottle cap
With the feature for keeping product airtightness and stabilizing quality, in terms of also having the function of antitheft unlatching and safety, therefore extensively
Apply on the bottled product for having content, so bottle cap be food, drink industry, wine, chemical industry, pharmacy industry upstream industry,
It is the key product of bottle container packaging.
Existing bottle cap is mostly that screw thread rotation formula is opened on the market, in bottle of taking when article, once bottle cap is opened, with sky
Phenomena such as oxidation deterioration easily occurs for substance in the bottle of gas contact influences the quality for saving object.
Utility model content
Based on this, the purpose of the utility model is to provide a kind of seal bottle caps, with upper cover and lower cover, in use,
It only needs to open the upper cover, can take vial product, reduce the contact area of substance and air in bottle, and then extend and save
Phase.
A kind of seal bottle cap, characterized by comprising: lower screw thread, institute is arranged in upper cover and lower cover, the lower cover lower inside
It states lower cover upper outside and upper screw thread is set, through-hole is arranged in the lower cover center upper portion；Upper screw thread described in the upper cover fit inside
Screw thread is set.
Compared with the existing technology, seal bottle cap described in the utility model only needs to open on described when taking out article in bottle
Lid delays vial product rotten to reduce the contact area of vial product and air when unlatching bottle cap takes article, thus
Extend shelf lives.
Further, upper flange is set between the through-hole and the lower cover top edge；When the upper cover lid is closed to described
Lower when covering, the upper flange upper surface touches on the upper cover medial surface, to increase the airtightness of the seal bottle cap.
Further, lower flange is set on the inside of the upper cover, the lower flange is mutually engaged with the upper flange；The lower flange
It is engaged with the upper flange, to increase the airtightness of the seal bottle cap.
Further, flexible gasket is arranged in the upper cover top inner surface；The flexible gasket fills the upper flange under
Gap between flange, to increase the airtightness of the seal bottle cap.
Further, the flexible gasket center is downwardly convex；The upper cover lid close to it is described it is lower cover when, in the gasket
Centre protrusion, covers the through-hole in the lower cover center, to increase the air-tightness of the seal bottle cap.
Further, the flexible gasket is made of environment-friendly materials.
Further, the upper cover is that environment-friendly materials are made with lower cover.
Further, the upper cover and lower cover outer surface are respectively provided with anti-skid chequer；The anti-skid chequer makes described close in unlatching
The frictional force for sealing bottle cap Shi Shouyu bottle cap increases, to reach labour-saving effect.
In order to better understand and implement, according to the present invention will be described in detail below with reference to the accompanying drawings.
Detailed description of the invention
Fig. 1 is the utility model closed bottle cap structural schematic diagram；
Fig. 2 is the utility model closed bottle cap schematic diagram of internal structure.
Specific embodiment
Embodiment 1
It is respectively that the utility model seal bottle cap structural schematic diagram and the utility model are close please refer to Fig. 1 and Fig. 2
Seal closure inside structural schematic diagram.A kind of seal bottle cap, characterized by comprising: upper cover 11 and lower cover 21, under the lower cover 21
Lower screw thread is set on the inside of portion, and upper screw thread is arranged in 21 upper outside of lower cover, and through-hole 22 is arranged in 21 center upper portion of lower cover；Institute
State upper screw thread setting screw thread described in 11 fit inside of upper cover；The seal bottle cap only needs to open on described when taking out article in bottle
Lid 11 delays vial product rotten to reduce the contact area of vial product and air when unlatching bottle cap takes article,
To extend shelf lives.
Further, upper flange 23 is set between 21 top edge of the through-hole 22 and the lower cover；When the upper cover 11 is covered
When closing on the lower cover 21,23 upper surface of upper flange is touched on 11 medial surface of upper cover, to increase described close
Seal the airtightness of bottle cap.
Further, lower flange 13 is set on the inside of the upper cover 11, and the lower flange 13 is engaged with 23 phase of upper flange；Institute
It states lower flange 13 to be engaged with the upper flange 23, to increase the airtightness of the seal bottle cap.
Further, flexible gasket 12 is arranged in 11 top inner surface of upper cover；The flexible gasket 12 is filled described convex
Gap between edge 23 and lower flange 13, to increase the airtightness of the seal bottle cap.
Further, 12 center of flexible gasket is downwardly convex；It is described when the lid of upper cover 11 is closed onto the lower cover 21
12 center projections of gasket cover the through-hole 22 in 21 center of lower cover, to increase the air-tightness of the seal bottle cap.
Further, the flexible gasket is made of environment-friendly materials.
Further, the upper cover is that environment-friendly materials are made with lower cover.
Further, the upper cover and lower cover outer surface are respectively provided with anti-skid chequer；The anti-skid chequer makes described close in unlatching
The frictional force for sealing bottle cap Shi Shouyu bottle cap increases, to reach labour-saving effect.
The following detailed description of the specifically used process of the utility model seal bottle cap:
The utility model seal bottle cap covers when on bottle, and the lower screw knob that 21 lower inside of lower cover is arranged is existed
On the screw thread of bottle, then the upper spiral shell of matched 21 upper outside of the lower cover setting by the inside thread sum of the upper cover 11
Line, by 11 knob of upper cover above the lower cover 21；It is upper on lower flange 13 and the lower cover 21 in the upper cover 11
23 phase of flange occlusion, the gasket 12 by the gap filling between the upper flange 23 and the lower flange 13, meanwhile, it is described
12 center of gasket covers the through-hole 22 at 21 middle part of lower cover, to increase the airtightness of the seal bottle cap.
When placing an article in bottle, lower cover 21 is removed from son, article is fitted into bottle, due to 21 lower opening of lower cover
Area is big, can place an article in bottle rapidly；When taking out article from bottle, the upper cover 11 need to only be taken from the lower cover 21
Under, article can be taken out from the through-hole 22 on the lower cover 21, since 22 area of through-hole is smaller, so as to reduce vial
The contact area of product and air reaches and delays article rotten, the purpose to extend the shelf life.
Compared with the existing technology, seal bottle cap provided by the utility model has good in such a way that upper cover and lower cover combine
Good airtightness, meanwhile, it, can be by only opening upper cover, to subtract when taking article by way of through-hole is set on lower lid
