A kind of good simple medicine bottle of leakproofness
Technical field
The present invention relates to a kind of for containing the sealed vial of solid kind drug.
Background technique
Most solid class drug at present, such as vitamin B2, vitamin C, coumpound diclofenac sodium and chlorphenamine maleate piece etc. are all using small shape
An important factor for material bottle encapsulates sale, therefore whether the leakproofness of bottle is well at drug pot-life length.It is general this
A little medicine bottles are sealed using clad aluminum paper tinsel film, are then equipped with tool internal thread bottle cap to tighten bottleneck, so admittedly
So before opening be in medicine bottle in the state that is isolated from the outside world, will not make moist, once but medicine bottle arrived in user hand, pass through
It seals off, just only remains bottle cap as moisture-proof means.But bottle cap is only screwed on bottleneck periphery with simple screw thread, and leakproofness obtains
Less than guarantee, often one bottle of medicine, which is not finished also, just has begun moist tacky phenomenon and produces.If adopted to position of bottleneck
With it is complicated detour, the structure of multi-sealed circle is sealed, and seem excessively cumbersome, and cost can improve many.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of good simple medicine bottle of leakproofness.
The solution that the present invention solves its technical problem is:
A kind of good simple medicine bottle of leakproofness, including the body with bottleneck and the bottle cap on the bottleneck,
The bottleneck is integrally in straight circular cylinder type, and the upper limb of upper end opening and the opening is in up big and down small horn-like, outside the lower part of bottleneck
Outwardly protrude a circle step week;The bottle cap is elastic material component, and interior bottom is equipped with sterile rubber washer, the sterile rubber
The adjacent edges of rubber gasket are equipped with circular pit, and the peripheral wall of bottle cap most lower edge is equipped with retaining ring;Retaining ring hooks the bottom of the step
So that the state that entire bottle cap pushes and bottleneck upper end opening upper limb is maintained to be pressed into the circular pit.
As a further improvement of the above technical scheme, the peripheral wall top of the bottle cap is outwardly raised.
As a further improvement of the above technical scheme, the bottle cap is PET component, and the body is PP component.
As a further improvement of the above technical scheme, the bottleneck on it end opening upper limb until the step between
One section, periphery is smooth.
The beneficial effects of the present invention are: retaining ring hooks natural when bottleneck lower step due to the elasticity of bottle cap itself
Downward pressure will be generated by bottle cap integrated drop-down, bottleneck upper limb is enabled to be embedded into the circular pit of sterile rubber washer, this
Sample bottle mouth top will be completely wrapped, and will not be leaked out, and sealed damp-proof effect is reached.And opening bottle also need to only use commonly
Strength, which pulls bottle cap, can disengage it from bottleneck, and opens to be repeated several times with this operation of closed bottle and be also hardly damaged portion
Part is durable.It present invention can be suitably applied to contain solid drugs.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described.Obviously, described attached drawing is a part of the embodiments of the present invention, rather than is all implemented
Example, those skilled in the art without creative efforts, can also be obtained according to these attached drawings other designs
Scheme and attached drawing.
Fig. 1 is partial cross-sectional structural diagram of the invention;
Fig. 2 is the partial enlarged view of the enclosed part of Figure 1A circle.
Specific embodiment
It is carried out below with reference to technical effect of the embodiment and attached drawing to design of the invention, specific structure and generation clear
Chu, complete description, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of the embodiment, rather than whole embodiments, based on the embodiment of the present invention, those skilled in the art are not being paid
Other embodiments obtained, belong to the scope of protection of the invention under the premise of creative work.In addition, be previously mentioned in text
All connection/connection relationships not singly refer to that component directly connects, and referring to can be added deduct according to specific implementation situation by adding
Few couple auxiliary, Lai Zucheng more preferably coupling structure.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
Referring to Fig.1~Fig. 2, a kind of good simple medicine bottle of leakproofness including the body 2 with bottleneck 21 and are mounted in institute
State the bottle cap 1 on bottleneck 21, it is in straight circular cylinder type that the bottleneck 21 is whole, and the upper limb of upper end opening and the opening is in up big and down small
Horn-like, the lower, outer perimeter of bottleneck 21 outwardly protrudes a circle step;The bottle cap 1 is elastic material component, and interior bottom is equipped with
Sterile rubber washer 3, the adjacent edges of the sterile rubber washer 3 are equipped with circular pit, and the peripheral wall of bottle cap 1 most lower edge is equipped with button
Ring 11;Retaining ring 11 hooks the bottom of the step so that entire bottle cap 1 pushes and 21 upper end opening upper limb of bottleneck is maintained to be pressed into institute
State the state of circular pit.Horn-like opening upper limb makes it easier to be embedded into circular pit and seal.
It is further used as preferred embodiment, the outwardly protrusion on the peripheral wall top of the bottle cap 1.Using this to
Outer protrusion borrows power, and user is easier to pull open bottle cap when wrapping bottle cap with handbag.
It is further used as preferred embodiment, the bottle cap 1 is PET component, and the body 2 is PP component.
Be further used as preferred embodiment, the bottleneck 21 on it end opening upper limb until between the step
One section, periphery is smooth.In other words, present invention eliminates the structures that is screwed on traditional between bottle cap and bottleneck, because working as retaining ring
Step is clasped, the elastic force of generation is compacted downwards rubber ring, and sealing has needed enough to seal bottleneck, without to bottle system
Complicated helical structure is made, production cost is saved.
Better embodiment of the invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make various equivalent modifications on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent variation or replacement are all included in the scope defined by the claims of the present application.
