Description

A kind of chemical vessel

Technical field

The utility model relates to a kind of chemical vessel.Conventionally, this chemical vessel is to be carried out corporation and made a kind of bottle with handle by high density polyethylene (HDPE) (HDPE), and this container has round vase shape profile conventionally.

Background technology

The Plastic Drum of storage chemicals, is generally formed by high density polyethylene (HDPE) (HDPE) corporation.In fact, this bottle is combined by two parts, so its parting knit line extends to the bottle mouth position on bottle top from bottom, this parting knit line is extended to the bottom of container.

But chemicals, especially has volatile liquid, in storage, transport and use procedure, unavoidably have rock or temperature raise situation, at this moment, the chemical vessel internal gas pressure of storage chemicals will increase, and easily causes container to break or bottle body bottom projection along parting knit line place; In addition, the Plastic Drum of storage of volatile, because bottle mouth position is a plane, belongs to plane-plane contact with pad, and leak tightness is general, has overlap situation when Plastic Drum becomes mould in addition, and leak tightness more cannot ensure.

In prior art, the technology that overcomes these two shortcomings is generally to increase wall thickness or at parting clutch line place, reinforcement feature is set the bearing pressure that strengthens container, but cost is higher and complex structure, and processing is difficult for; The mode that generally can adopt in addition exterior and interior cover for enhanced leaktightness, also makes complex structure, and tooling cost is high.

Utility model content

In order to overcome above-mentioned defect, the utility model provides a kind of chemical vessel, has overcome the shortcoming that leak tightness is low, bearing pressure is not high.

The technical scheme in the invention for solving the technical problem is: a kind of chemical vessel, comprise bottle, bottle cap and handle, its overlap of the bottle mouth position on bottle top is between bottleneck end face and whorl of bottleneck, and bottleneck end face is circular arc, and bottleneck end face belongs to line face with pad and contacts.

Further, this chemical vessel is made up of high density polyethylene (HDPE) (HDPE).

Further, this chemical vessel is made up of Secco 5502FA.

Further, bottleneck end face is longitudinally convex in the arc-shaped, forms an entirety along annular arrangement bottleneck one circle.

Further, handle vertical portion divides relative bottle plane almost vertical with bottle bottom surface.

Further, bottle bottom surface concaves in the arc-shaped along parting knit line.

Further, this chemical vessel comprises a handle integrally formed with chemical vessel.

Further, after pad is extruded by HDPE foaming, make through the two multiple films of tetrafluoroethylene.

Further, chemical vessel wall thickness is preferably 1.5 to 1.8mm.

Further, chemical vessel is for storing and transport liquid volatility pharmaceutical chemicals.

The beneficial effects of the utility model: compared with general Plastic Drum, bearing pressure is high, good airproof performance, handle grip feeling are good.

Detailed description of the invention

Although the utility model tolerable adopts many multi-form embodiment, its shown in the drawings and will be in this article being described in specific embodiment in detail, the disclosure that should understand these embodiment will be regarded as the example of principle, and is not intended to the utility model to be restricted to shown and described specific embodiment.In the following description, identical reference numerals is used for identical, the similar or corresponding part of the some views that are indicated in accompanying drawing.This detailed description defines the implication of term used herein, and has described embodiment particularly to make those skilled in the art implement the utility model.

A kind of chemical vessel as shown in Figure 1, Figure 2 and Figure 3, comprises bottle 1, bottle cap 2 and a handle 3 integrally formed with chemical vessel of a full symmetric, and this chemical vessel is made up of high density polyethylene (HDPE) (HDPE), preferably Secco 5502FA type; Handle 3 vertical portion divide relative bottle plane 6 almost vertical with bottle bottom surface 7, bottle bottom surface 7 concaves in the arc-shaped along parting knit line 8, the air pressure of such structure in can actv. equilibration flask, prevent that bottle from breaking or bottle bottom surface 7 antiarch along parting knit line 8, make bottle 1 bear the air pressure ability of chemicals stronger; And it is a plane but not curved surface in the past that handle 3 vertical portion are divided relative bottle plane 6, make handle 3 places hold hand spaces more spacious, handle grip feeling is better.

Bottle end face as shown in Figure 4, its overlap 9 is between bottleneck end face 4 and whorl of bottleneck 5, and bottleneck end face 4 is longitudinally convex in the arc-shaped, forms an entirety along annular arrangement bottleneck one circle with bottle end face, such structure makes bottleneck end face 4 and pad belong to line face to contact, better tightness.As shown in Figure 5, left one side of something is the front elevation of the utility model bottle end face, right one side of something is the front elevation of its bottle end face of chemical vessel Plastic Drum on the market, its bottleneck end face and pad are commonly plane-plane contact, be that bottleneck end face and pad are a plane, but Plastic Drum always produces overlap 9 in the time of parting, does not therefore accomplish absolute plane-plane contact, poor sealing.

More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification sheets, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
