Description

Flat-shaped outlet cream packing bags

The utility model belongs to the manufacturing of cream packing bags.

The packing of paste daily necessities such as toothpaste type, toiletries outlet at present is circle, after extruding, lotion is cylinder, with toothpaste is example, if cylindrical lotion is coated with full toothbrush bristle then causes waste, and the cylinder lotion can not be smooth, uniformly between bristle and tooth, little with the tooth contact surface, brush gets up to be broken into easily fritter and falls down from toothbrush and become scattered about the mouth, be the uncomfortable waste that causes again, very inconvenient to the customer, also there is this type of problem in other lotion daily necessities.

The purpose of this utility model is to provide a kind of flat-shaped outlet cream packing bags, it is a kind of very practical packaging bag, adopt the exit passageway of special shape, make the lotion that is extruded be bandlet shape even, smooth, attractive in appearance, can evenly be coated with full brush, can overcome above-mentioned shortcoming, the utility model modern design, use reliably, convenient, welcome by consumers in general.

The utility model comprises the cream packing bags body and the outlet of cylindric shape, and exit passageway is the flattened oval cylinder, and oval radius dwindles gradually to the exit from the inside to the outside, and the exit is flat elliptical shape.

The utility model is described in detail as follows with reference to accompanying drawing:

Fig. 1 is flat-shaped outlet cream packing bags generalized section; Fig. 2 is flat-shaped another generalized section of outlet cream packing bags; Fig. 3 is flat-shaped outlet cream packing bags exit passageway flat cutting scheme drawing.

As shown in the figure, the 1st, bag is cylindric, and the 2nd, the exit passageway outer wall, the 3rd, exit passageway, the 4th, the exit, the 5th, the button lid, the 6th, the exit passageway inwall, it is a parabolic type; A-A, B-B, C-C, D-D and E-E, be respectively exit passageway crosscut scheme drawing, exit passageway 3 is circular with bag 1 junction, gradually becomes flat elliptical shape from E-E to A-A, oval radius 4 dwindles gradually to the exit from the inside to the outside, and the major radius of ellipse is 2～4 times of short radius; The cylinder that the outer wall of exit passageway 3 is rounded, trapezoidal or flat, exit 4 can connect 5 sealings of button lid, and when outer wall was circle, trapezoidal cylinder, common screw top sealing can be adopted in exit 4.

Exit passageway inwall of the present utility model is a parabolic type, be the design of flattened oval cylinder, purpose is for reducing the pressure to lotion gradually, external pressure is unlikely to change too fast in when lotion is extruded, expand when avoiding lotion to extrude, exit passageway and bag junction are designed to the wide-mouth circle, are for making unlikely too effort when squeezing lotion and directly be not designed to flat.This kind design plan can easily be extruded the bandlet shape, smooth, uniform lotion.Exit width is equivalent to general toothbrush (with toothpaste is example, and other products designs according to situation) width (about 1 centimetre), and for the effect that guarantees exit passageway is achieved, its length should be not less than 3 centimetres.

The utility model can make the paste product extrude even, smooth, bandlet shape lotion and be applied to and make use.Still be example with toothpaste, can unlikely waste be coated with completely whole toothbrush, can also make toothpaste flat, place between toothbrush bristle and the tooth uniformly, increase contact surface, strengthen the effect that cleans the teeth.The lotion novel and beautiful of extruding, the appearance uniqueness causes customer's interest and attention easily, strengthens desire to buy, because this product is convenient, practicality has solved the defective of old technology, after putting goods on the market, old product will be eliminated gradually.When new old product placed in face of the customer simultaneously, customer's purchase intention will be significantly, so the utility model is being contained huge commercial value.
