Description
Technical field
Field of cell culture is the utility model is related to, more particularly to a kind of Tissue Culture Flask bottle for having and thickening design
Lid.
Background technology
Sterile product during cell culture medium, and be existing in the form of a solution, had once being contacted with external environment
Contaminated risk, therefore, bottle air-tightness should be ensured by dispensing the container of cell culture medium, ensure the pressure-resistant of bottle cap again
Power.Carbon dioxide is had during storage in cell culture medium liquid to produce, culture medium bottle cap is in the situation without particular design
Under due to carbon dioxide yield it is excessive, be inverted bottle too high pressure, frequently can lead to bottle cap storage some months even one
Crack occurs in the marginal position on top after month, causes nutrient solution to pollute and leak.
The enterprise of existing production Tissue Culture Flask domestic at present, is not culture medium manufacturing enterprise, does not realize really
To the importance of the sealing stability of bottle cap, stability also is carried out to cell culture medium bottle cap without enterprise and sealing carries out volume
Outer concern and processing.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in construction, good airproof performance, having of being not easily broken
Thicken the cell culture bottle cap of design.
The utility model is a kind of to have a cell culture bottle cap for thickening design, including body of the bottle lid, inside body of the bottle lid
Screw thread is provided with side wall, wherein：Thickening layer, the bottom of thickening layer and the top of screw thread are laid with body of the bottle lid exterior side wall
Positioned at same level, the centre position of body of the bottle lid inner tip is horizontally disposed annular projection, protruding apex
The distance of apical position of outer ledge and body of the bottle lid internal side wall be 3~5mm.
The utility model is a kind of to have the cell culture bottle cap for thickening design, wherein the projection is horizontally disposed
In the centre position of body of the bottle lid inner tip.
The utility model is a kind of to have the cell culture bottle cap for thickening design, wherein the raised longitudinal section is inversion
Triangular structure, the top integrally connected inside protruding apex and body of the bottle lid.
The utility model is a kind of, and there is the cell culture bottle cap difference from prior art for thickening design to be：This reality
Thickening layer is provided with the exterior side wall of body of the bottle lid with new, increases the pressure-resistant degree of body of the bottle lid turning position, even if
Apply larger pressure to body of the bottle lid 1 during bottle cap is screwed, can also ensure the firm of body of the bottle lid and stably, keep away
Exempt from due to pressure is excessive and caused by bottle cap rupture situation occur.The bottom of thickening layer and the top of screw thread are located at same level
Face, the position of thickening layer keep good with the position of screw thread and are connected, and it is thin will not to occur connection between screw thread in thickening layer
Weak area, the firmness of the body of the bottle lid further enhanced.The centre position of body of the bottle lid inner tip has been wholely set annulus
Shape is raised, and the distance of the outer ledge of protruding apex and the apical position of body of the bottle lid internal side wall is 3~5mm, is both added
The thickness on body of the bottle lid top, and the effect of reinforcing is served to the position of body of the bottle lid most fragile, and raised longitudinal section
For inverted triangular structure, itself there is good stability, greatly reduce the generation of body of the bottle lid rupture event, reduce
Pollution and risk of leakage.The utility model can still ensure good sealing in the case that internal pressure is excessive
Effect, the pH value of stable prod, ensure the stability of product.
It is a kind of to the utility model below in conjunction with the accompanying drawings that there is the cell culture bottle cap for thickening design to be described further.
Brief description of the drawings
Fig. 1 is a kind of front sectional view with the cell culture bottle cap for thickening design of the utility model.
Embodiment
As shown in figure 1, being a kind of front sectional view with the cell culture bottle cap for thickening design of the utility model, wrap
Body of the bottle lid 1 is included, the lower position of the internal side wall of body of the bottle lid 1 is provided with screw thread 4, and body of the bottle lid 1 is trained by screw thread and cell
Support bottle connection.The upper position of the exterior side wall of body of the bottle lid 1 is laid with thickening layer 2, the bottom of thickening layer 2 and the top of screw thread 4
Positioned at same level.The centre position of the inner tip of body of the bottle lid 1 is horizontally disposed annular projection 3, projection 3
Longitudinal section is inverted triangular structure, raised 3 tops and the top integrally connected inside body of the bottle lid 1, outside raised 3 tops
The distance of lateral edges and the apical position of the internal side wall of body of the bottle lid 1 is 3~5mm.
The utility model is a kind of to have the cell culture bottle cap for thickening design, is set in the exterior side wall of body of the bottle lid 1
Be equipped with thickening layer 2, increase the pressure-resistant degree of the turning position of body of the bottle lid 1, during bottle cap is screwed to body of the bottle lid 1
Apply larger pressure, can also ensure the firm of body of the bottle lid 1 and stably, avoid due to pressure is excessive and caused by bottle cap break
Situation about splitting occurs.The bottom of thickening layer 2 is located at same level, position and the screw thread 4 of thickening layer 2 with the top of screw thread 4
Position keeps good linking, will not occur connecting weak area, the bottle cap further enhanced between screw thread 4 in thickening layer 2
The firmness of body 1.The centre position of the inner tip of body of the bottle lid 1 has been wholely set annular projection 3, raised 3 tops
The distance of outer ledge and the apical position of the internal side wall of body of the bottle lid 1 is 3~5mm, has both added the thickness on the top of body of the bottle lid 1
Degree, and the effect of reinforcing is served to the position of the most fragile of body of the bottle lid 1, and also the longitudinal section of projection 3 is inverted triangle
Structure, itself there is good stability, greatly reduce the generation of the rupture event of body of the bottle lid 1, reduce pollution and leakage
Risk.The utility model can still ensure good sealing effectiveness, stable prod in the case that internal pressure is excessive
PH value, ensure the stability of product.The utility model is simple in construction, good airproof performance, is not easily broken, and has compared with prior art
There is clear advantage.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical scheme of utility model is made, the protection of the utility model claims book determination all should be fallen into
In the range of.
