Detailed ways

The following are specific embodiments of the invention and combined with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

Example 1

As shown in Figures 1 and 2, an easily separable pulp container has the same wall thickness for ease of manufacture. Specifically, the easily separable pulp container includes a conical container body 10 made of pulp material. The opening of the conical container body 10 has an outwardly folded edge 20 , and the edge 20 is integrally formed with the conical container body 10 .

Further, the edge 20 and the axis line of the conical container body 10 form an included angle a of 90°. The included angle a of 90° can facilitate the processing along the edge 20 and the subsequent release from the mold. Of course, it can also be an included angle greater than 90°.

The outer wall of the open end of the conical container body 10 is integrally formed with a radially outwardly convex bulge restricting portion 30, and when the two conical container bodies 10 are nested, the opening of the outer conical container body 10 is restricted to the inner cone The lower side of the highest point of the uplift of the uplift restricting portion 30 of the container body 10 .

Further, as shown in FIG. 4 , the uplift restricting portion 30 of this embodiment includes a conical separation surface 300 disposed on the outer wall of the open end of the conical container body 10 , and the diameter of the upper end of the conical separation surface 300 is smaller than the diameter of the lower end of the cone separation surface 300 , The diameter of the lower end of the conical separation surface 300 is larger than the opening diameter of the conical container body 10 and the thickness between the conical separation surface 300 and the open inner wall of the conical container body 10 gradually increases from top to bottom, and the conical separation surface 300 and the edge 20 are formed. An acute angle b less than 90° can also be called a negative angle. The conical separation surface 300 thickens the wall thickness of the container downward, and the thickened wall thickness can form a position limit when the two containers are nested, that is, the thickest wall thickness of the inner container can be opposite to the outer side. The container opening forms a restrictive barrier to ensure that the inner container cannot enter excessively into the outer container.

The bulging restricting portion 30 further includes a conical restricting surface 301 connected to the lower end of the conical separating surface 300 and smoothly connected with the outer wall of the conical container body 10 . Continuing the above statement, the conical confinement surface 301 can be used to further limit the position in advance. At the same time, the conical confinement surface 301 and the opening of the outer container are in a line-to-line contact manner, which can not only reduce the contact surface, but also The gap between the outer wall of the inner container and the inner wall of the outer container can also be enlarged to facilitate the subsequent separation of the two. Due to the conical separation surface 300, the distance between the conical limiting surface 301 and the inner wall of the conical container body 10 decreases gradually from top to bottom, and finally returns to the equal wall thickness of the conical container body 10.

Preferably, the bulging limiting portion 30 further includes a middle cylindrical surface 302 , the upper end of the middle cylindrical surface 302 is connected to the lower end of the conical separating surface 300 , and the lower end of the middle cylindrical surface 302 is connected to the upper end of the conical limiting surface 301 . The middle cylindrical surface 302 can facilitate the processing and manufacture of the entire container, and at the same time, the phenomenon of mutual abrasion and damage due to sharp corners and edges will not occur in the subsequent nesting process, and at the same time, the overall appearance of the container is more beautiful.

Specifically, the cone separating surface 300 and the cone limiting surface 301 form an obtuse angle c greater than 120°. For example, 170° or 160°, etc., avoid that the angle is too small to form a large-area contact method between surfaces, which is not conducive to subsequent separation.

Next, as shown in FIGS. 1 , 2 and 4 , an inner conical surface 100 is provided on the open inner wall of the conical container body 10 , and the inner diameter of the upper end of the inner conical surface 100 is larger than the inner diameter of the lower end of the inner conical surface 100 . The upper end of the inner conical surface 100 is connected with the edge 20 through the inner fillet 101 . The inner conical surface 100 is connected with the inner wall of the conical container body 10 through the arc-shaped transition concave surface 104 .

The inner conical surface 100 can facilitate demoulding, and at the same time, can also facilitate the nesting of two conical container bodies.

Also, the cone separation surface 300 and the inner cone surface 100 form an angle of less than 10°, eg, 8°. The cone separation surface 300 is in contact with the upper end of the inner cone surface 100 to ensure that an annular gap is formed between the cone separation surface 300 and the lower side of the upper end of the inner cone surface 100 to reduce the contact surface and improve separation performance.

As shown in FIGS. 1 , 2 and 3 , the inner wall of the conical container body 10 is provided with a plurality of inner protrusions 102 that are evenly distributed around the circumference, and the upper end of the inner protrusions 102 is located under the open end of the conical container body 10 The lower end of the inner protrusion 102 is extended to the inner bottom of the conical container body 10, and the outer wall of the conical container body 10 is provided with a number of inner grooves 103 corresponding to the inner protrusions 102 one-to-one. The inner grooves 103 The lower end communicates with the outside world. The inner protrusion 102 can form structural reinforcement, and at the same time, it can also form a directional nesting when the two conical container bodies 10 are nested, because the inner protrusion 102 can enter from the lower end of the inner groove 103 to achieve directional nesting. , so as to prevent the two adjacent conical container bodies 10 from rotating in the circumferential direction and forcing the two conical container bodies 10 to be nested tighter, which is inconvenient for subsequent separation.

In addition, the inner bottom of the conical container body 10 is provided with an upper convex surface, and the outer bottom of the conical container body 10 is provided with an upper concave surface. Structural strength of the container bottom.
