Description

A kind of scarfing blade type plastic bottle closure that carries

Technical field

The utility model relates to a kind of plastic bottle closure, specifically a kind of scarfing blade type plastic bottle closure that carries.

Background technology

Present most of medicine all adopts plastic bottle packing, plastic bottle or glass bottle packaging that the food that also has adopts the high molecule plastic material to make.In order to reach health, purpose of safety, adopt one deck compound seal paper usually, with packing material in the bottle and external isolation.In use, at first this layer sealed paper must be removed.Generally compound seal paper and mouth bonding are tighter, are not easy to open.A kind of simple design has been arranged, made the sealed paper at bottleneck edge have more a fritter, be used to draw back, but so also be difficult to it is opened fully.

The utility model content

The purpose of this utility model is to provide a kind of scarfing blade type plastic bottle closure that carries easy to use, simple in structure.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of scarfing blade type plastic bottle closure that carries comprises bottle cap body, is provided with the blade that a side has cutting edge at the inside face of bottle cap body.

Described blade is that the top has most advanced and sophisticated triangle, and most advanced and sophisticated pairing triangle edges is connected with the inside face of bottle cap body by the junction surface.

The parallel inside face that is posted by bottle cap body of described blade, itself and bottle cap body be arranged in parallel; Perhaps the inside face in bottle cap body is provided with and blade shapes and sizable groove, and blade is embedded in the groove on the bottle cap.

Described blade is leg-of-mutton plastic blade, and most advanced and sophisticated cooresponding triangle edges is one by junction surface and bottle cap body by mold or heat seal extrusion, is provided with the joint thickened area at blade near a side engagement portion of cutting edge.

The utlity model has following advantage:

1. the utility model comprises the integrated blade of a combination, has point of a knife and blade on it, can be used for cutting the sealed paper of bottleneck, and is easy to use.

2. the inside face of the utility model blade and bottle cap body designs for one, can add the one-shot forming in man-hour at bottle cap by improving mould, and is simple in structure.

3. the utility model can directly be severed sealed paper, reaches extraordinary effect, and Applicable scope is extensive.

The specific embodiment

From the bottle cap of band blade, comprise bottle cap body 1 as shown in Figure 1, hide a blade 2 in bottle cap inside.The inside face of blade and bottle cap body designs for one, can add the one-shot forming in man-hour at bottle cap by improving mould, also can triangular blade be engaged with bottle cap by the method for heat seal.

Blade 2 is leg-of-mutton plastic sheet, have point of a knife and blade on it, with a leg-of-mutton summit is most advanced and sophisticated 3, most advanced and sophisticated 3 use as point of a knife, be fixed on the bottle cap body 1 by junction surface 5 with most advanced and sophisticated 3 corresponding triangle bases, the side of any blade 2 between tip 3 and the junction surface 5 is provided with cutting edge 4; Leg-of-mutton base is to be one by junction surface 5 and bottle cap body 1 by mold or heat seal extrusion, and blade 2 be arranged its parallel inside face that is posted by bottle cap body 1 in parallel with bottle cap body 1.

Blade can be attached on the inside face of bottle cap, also can be provided with on the inside face of bottle cap body 1 and blade 2 shapes and sizable groove, and blade 2 is embedded in the groove on the bottle cap.

Cutting edge 4 its shapes of blade 2 can adopt different shapes such as the straight type sword of A, B matrix sword, C convex sword and D shaped form sword as shown in Figure 2.Point of a knife is enough sharp, can expose sealed paper.Multi-form blade can be used for the cutting of the sealed paper of heterogeneity, intensity, size.

Should there be certain intensity at junction surface 5, avoids coming off in cutting process, simultaneously also should be not really strong, can after finishing the cutting task, take off easily.In order to reach this purpose, in the Mould design process, can make the junction surface slightly thicker, and other part is thinner a little in the position of blade.Section-drawing as shown in Figure 3.Be provided with joint thickened area 6 at the junction surface of blade 2 close cutting edge 4 one sides, the junction surface that root is thicker can make blade can bear bigger stress.

The position of blade can adjust as required, for example for the particle tablet, blade can be placed on the position at close center, and opening is with less like this.And for packing, can make the as close as possible bottle of blade edge, the convenient use as the honey pot.

Build the Packaging Bottle of bottle cap and see Fig. 4.1 is bottle cap body, and 2 is blade, and 7 is bottle, and 8 is screw socket, and 9 for sealing paper;

During concrete operations:

Rotation bottle cap body 1, by screw socket 8 bottle cap is outwarded winding, after opening bottle cap, as shown in Figure 5, by junction surface 5 inside face of triangular blade 2 in bottle cap body 1 erected, puncture with most advanced and sophisticated 3 and seal paper 9 (it can be extrusion coating paper), to screwing tight direction rotation bottle cap, drive blade 2 and rotate, cutting edge 4 can be severed sealing paper 9.After the edge of a knife has cut, open bottle cap, blade 2 is removed, finish.
