Abstract

The utility model discloses a kind of drug packaging bottles, and the end of bottleneck neck is provided with bottleneck edge；The junction of the bottleneck neck and the bottleneck edge is provided with knuckle.The utility model drug packaging bottle is provided with knuckle in the junction of bottleneck neck and bottleneck edge, so that shortening the bottle embryo cooling time after the cooling wind pressure of cooling bottle embryo after bottle is blown in raising；It improves in the case where blowing bottle efficiency, it is possible to prevente effectively from bottleneck cracks.

Description

Drug packaging bottle

Technical field

The utility model relates to a kind of drug packaging bottles, specially liquid medicine packaging bottle；Belong to medical packaging field.

Background technique

Plastic bottle is a kind of packaging material for containing liquid, is first passed through after injecting machine material tube is heated at high temperature using hydraulic system height Bottle embryo is made after being incident upon injection mold cooling in pressure injection, finally carries out heating post-tensioning to bottle embryo embryo body by bottle blowing machine heating lamp box Bottle is made in blow molding, and bottleneck quality controls the design for depending primarily on injection mold mouth mold.

Utility model content

In order to improve the efficiency for blowing bottle, the blow gas pressure of cooling bottle embryo after blowing bottle is improved；Shorten bottle embryo it is cooling when Between.After improving technique, above-mentioned plastic bottle opening will appear bottleneck cracking phenomena during blowing bottle by bottle blowing machine once in a while, should Phenomenon will lead to plastics bottle product and leakage problem occurs.It has been investigated that as depicted in figs. 1 and 2, bottle in existing bottleneck design The junction of mouth neck 2 and bottleneck edge 1 is right angle；It is not in bottleneck problem of Cracking when blow gas pressure is lower than 1.2MPa；And it blows Atmospheric pressure, which improves, will lead to the ability reduction that bottleneck bears pressure.It can either improve and blow the purpose of the utility model is to provide one kind Bottle efficiency, and the drug packaging bottle that can effectively avoid bottleneck from cracking；The specific technical proposal is:

A kind of drug packaging bottle is provided with bottleneck edge in the end of bottleneck neck；The company of the bottleneck neck and the bottleneck edge The place of connecing is provided with knuckle.

Further, the radius of the knuckle is between 0.2-0.5mm.

Further, the drug packaging bottle is made of PP or PE material.

The utility model drug packaging bottle is provided with knuckle in the junction of bottleneck neck and bottleneck edge, so that improving It blows after bottle after the cooling wind pressure of cooling bottle embryo, shortens the bottle embryo cooling time, improve in the case where blowing bottle efficiency 10%, It is possible to prevente effectively from bottleneck cracks.

In figure: 1, bottleneck edge；2, bottleneck neck.

Specific embodiment

The utility model is made a more thorough explanation below with embodiment.The utility model can be presented as it is a variety of not Same form, should not be construed as limited to the exemplary embodiments described herein.

The spatially relative terms such as "upper", "lower" " left side " " right side " can be used herein for ease of explanation, for saying Relationship of the elements or features relative to another elements or features shown in bright figure.It should be understood that in addition in figure Except the orientation shown, spatial terminology is intended to include the different direction of device in use or operation.For example, if in figure Device is squeezed, and is stated as being located at other elements or the element of feature "lower" will be located into other elements or feature "upper".Cause This, exemplary term "lower" may include both upper and lower orientation.Device, which can be positioned in other ways, (to be rotated by 90 ° or is located at Other orientation), it can be interpreted accordingly used herein of the opposite explanation in space.

As shown in Figure 3, Figure 4, the drug packaging bottle in the present embodiment is provided with bottleneck edge 1 in the end of bottleneck neck 2；Bottle The junction of mouth neck 2 and bottleneck edge 1 is provided with knuckle.

The radius of knuckle should control between 0.2-0.5mm；The radius of knuckle is too small to be unfavorable for improving cooling The speed of wind；The radius of knuckle is too big, will lead to lengthening cooling time, is unfavorable for improving and blows a bottle efficiency.

Drug packaging bottle should be made of PP or PE material.PP material fusing point is higher, the tolerable 121 DEG C of sterilizings of product, system The finished product obtained has the characteristics that anti-impact force is strong, transparency is good, good with drug intermiscibility.PE material ageing resistance is strong, flows The characteristics of excellent performance, is more suitable for making lesser fillet.

The utility model drug packaging bottle is provided with knuckle in the junction of bottleneck neck and bottleneck edge, so that improving It blows after bottle after the cooling wind pressure of cooling bottle embryo, shortens the bottle embryo cooling time；It improves in the case where blowing bottle efficiency, it can be with Effectively bottleneck is avoided to crack.

Above-mentioned example is only intended to illustrate the utility model, and in addition to this, also there are many different embodiments, and these Embodiment be all those skilled in the art after comprehension the utility model thought it is also envisioned that therefore, no longer arrange one by one herein It lifts.
