This packing bottle includes bottle and bottle lid, its characterized in that: the lower half of bottle is square structure, and first one is the toper structure. There is a bottleneck external screw thread bottleneck outside, a bottle inner surface of the cover have with bottleneck external screw thread assorted bottleneck internal thread. The bottle lid is divided into upper strata and lower floor space, and two spaces of upper space separation are for can pack antioxidant and anti deliquescent agent respectively, and the bottleneck device of antioxidant and the similar inversion of anti deliquescent agent accessible is changed. Bottle and bottle lid inlayer add there is the one deck black film. The utility model discloses simple structure, reasonable in design has stronger practicality, can effectually reduce oxidation, the deliquescence of dehydrated medium, the risk of seeing the photolysis, has avoided culture medium, antioxidant simultaneously, has prevented that the possibility that biological chemistry reacts is sent out to the phase mixing between the deliquescent agent, can also in time change antioxidant and prevent the deliquescent agent through the bottleneck of placing upside down, reaches the purpose of long -term storage dehydrated medium.

Description

A kind of dehydrated medium package bottle special

Technical field

This utility model is related to a kind of medium package device, particularly to a kind of dehydrated medium package bottle special, belongs to In microbiological culture media Techniques of preserving field.

Background technology

Dehydrated medium is through filling needed for proper treatment, the formula according to various culture medium by the various composition of culture medium The mixing dividing is powdered.Take this powder wood to add distilled water in proportion and dissolve subpackage during use to sterilize, its advantage is culture medium Reach standardization, save the manufacturing time of culture medium.Early in four the fifties, American and Britain, Deng developed country are in a large number using dry Powder culture medium, and merchandized handling.China is started in the fifties, and the annual sales volume of current China dehydrated medium is Reach billions of units.So during my Company dehydrated medium, some easy deliquescence of customer response can be run into (as MS culture Base), oxidation (as selenite cystine dehydrated medium), see that light easily decomposes the culture of (many culture medium require keep in Dark Place) Base preserves the short period with regard to quality generation problem during using.

Utility model content

According to the deficiency in existing dehydrated medium use above, problem to be solved in the utility model is：There is provided a kind of Dehydrated medium deliquescence can be reduced, aoxidize, see a kind of labile package bottle special of light, be easy to its length in use Phase preserves.

The technical scheme in the invention for solving the above technical problem is：

A kind of dehydrated medium package bottle special, including bottle and bottle cap it is characterised in that：The lower half of described bottle For square structure, the first half is pyramidal structure.There is external thread of bottleneck, bottle cap inner surface has and external thread of bottleneck phase outside bottleneck The bottle cap female thread joined.Bottle cap is divided into two sheaf spaces, upper sheaf space and lower layer space to be spaced with similar inversion bottleneck portion, Putting has inversion external thread of bottleneck outside bottleneck, be inverted bottleneck and be furnished with an inversion bottle cap, its caping is made up of fine-structure mesh, is inverted in bottle cap Surface has and is inverted the inversion bottle lid female thread that external thread of bottleneck matches.Upper sheaf space is divided into two by interlayer further Space, antioxidant can be filled in a space, and Deliquescence-resistant agent is filled in another one space.

On this utility model bottle cap, sheaf space is connected with bottle space, and on bottle cap, sheaf space is filled with antioxidation and moisture resistance Solution agent, can play the effect reducing dehydrated medium oxidation and deliquescence；Antioxidant and Deliquescence-resistant agent separate that can prevent can The chemical reaction of energy, in order to avoid reagent lost efficacy；Antioxidant and Deliquescence-resistant agent are separated with culture medium, can prevent itself and culture medium phase Mixing.

The more excellent scheme of this utility model is：

Described bottle and bottle cap internal layer, added with one layer of black film, prevent light from passing through, and see that light holds labile dry powder to some Culture medium plays a protective role.

Described bottle appearance and bottle cap outer surface are equipped with perpendicular anti-slip veins, enhance the skidproof effect of device.

This utility model structure is simple, reasonable in design, has stronger practicality, can effectively reduce dehydrated medium Oxidation, deliquescence, see the risk of photolysis, avoid culture medium, antioxidant, the possibility of anti-deliquescent agent phase mixing simultaneously, also may be used Antioxidant is changed in time by inverted bottleneck and anti-deliquescent agent can preserve dehydrated medium for a long time.
