Abstract
Description
- The present utility model pertains to the technical field of packaging, and particularly relates to a snap-fitting structure of paper and plastic container.
- Beverage cups generally use polyester (PET), polyethylene (PE) or polypropylene (PP) as a raw material, which is heated at a high temperature after the addition of an organic solvent and is then molded by method of blow molding, extrusion or injection molding in a mold of plastics. As plastics are hardly degradable and have a low recycling rate, they are very environmentally unfriendly. At present, many items have begun to use environmentally friendly paper material, such as hand bags and milk bags, but there is no precedent for using paper material to make beverage cups. Judging from hardness and moldability, paper material can absolutely be used to make beverage cups. Therefore, using paper material as the main material to produce beverage cups not only is environmentally friendly and safe but also forms a more beautiful appearance than that of plastic bottles and will be favored by more people. However, the covers of all beverage cups used at present directly cover the containers and are not tight, so the beverage or suspension is liable to spillover and meanwhile the covers are easily disengaged with an external force.
- In light of the above, the present utility model provides a novel snap-fitting structure of paper and plastic container of which cover body is not easily disengaged, to solve the foregoing problems.
- A snap-fitting structure of paper and plastic container is provided. The paper and plastic container comprises a container, and a cover body covering the container. The container comprises a body, and a clamping portion extending out of the edge of the body. The clamping portion comprises a connecting portion connected to the body, and a clamp ring extending out of the connecting portion. In a cross section along the central axis of the body, the included angle between the contour line of the connecting portion and the central axis of the body is an acute angle, and the contour line of the clamp ring is parallel to the central axis of the body. The cover body comprises a cover bottom, a cover wall extending out of the edge of the cover bottom, and a flange arranged on the inner side wall of the cover wall. The outer diameter of the clamp ring is equivalent to the inner diameter of the cover wall. The flange and the cover bottom are arranged at an interval, and the clamp ring is clamped between the flange and the cover bottom when the cover body covers the container.
- Further, the flange and a free end of the cover wall are arranged at an interval.
- Further, in a cross section along the central axis of the body, the contour line of the flange is arc-shaped.
- Further, the distance from the side wall of the body to the clamp ring is equal to the height of the arc of the flange.
- Further, in the direction along the central axis of the body, the height of the clamp ring is equal to the minimum distance from the flange to the cover bottom.
- Compared with the prior art, the container and the cover body of the snap-fitting structure of paper and plastic container provided by the present utility model have the clamping portion and the flange, respectively. When the cover body covers the container, as the outer diameter of the clamp ring is equivalent to the inner diameter of the cover wall, the clamp ring deforms under the pressing of the flange. When the clamp ring is beyond the flange, the clamp ring restores to the original state or is still in a deformed state to abut against the cover wall, and is clamped between the cover bottom and the flange, such that the container and the cover body are fitted in a covering manner and are not disengaged without an external force.

FIG. 1 is a structural schematic view of a snap-fitting structure of paper and plastic container provided by the present utility model. -
FIG. 2 is a sectional structural schematic view of the snap-fitting structure of paper and plastic container inFIG. 1 . - Below a specific embodiment of the present utility model is further described in detail. It should be understood that the description of the embodiment of the present utility model is not intended to limit the protection scope of the present utility model.
-
FIG. 1 andFIG. 2 are structural schematic views of a snap-fitting structure of paper and plastic container provided by the present utility model. The paper cup in the snap-fitting structure of paper and plastic container comprises acontainer 10, and acover body 20 covering thecontainer 10. It can be understood that thecontainer 10 and thecover body 20 both can be pressed from paper pulp or paper and plastic material. - The
container 10 comprises abody 11, and aclamping portion 12 extending out of the edge of thebody 11. It is conceivable that thecontainer 10 may further comprise some other functional structures, such as a cup handle part and an ornamental part, which are technologies known to those skilled in the art, and will not be described in detail here. Thebody 11 is used to hold various items, such as liquid and suspension, which is an existing technology and will not be described in detail here. Theclamping portion 12 comprises a connectingportion 121 connected to thebody 11, and aclamp ring 122 extending out of the connectingportion 121. In a cross section along the central axis of thebody 121, the included angle between the contour line of the connectingportion 121 and the central axis of thebody 11 is an acute angle, and the contour line of theclamp ring 122 is parallel to the central axis of thebody 11. - The
cover body 20 comprises acover body 21, acover wall 22 extending out of the edge of thecover body 21, and aflange 23 arranged on the inner side wall of thecover wall 22. It is conceivable that thecover body 20 may further comprise some other functional structures, such as a lifting handle and a jack. Thecover body 21 is a technology known to those skilled in the art, and will not be described in detail here. Theflange 23 and thecover bottom 21 are arranged at an interval. In the direction along the central axis of thebody 11, the height of theclamp ring 122 is smaller than or equal to the minimum distance from theflange 23 to thecover body 21. When thecover body 20 covers thecontainer 10, theclamp ring 122 is clamped between theflange 23 and thecover bottom 21. In order to make theclamp ring 122 contact a surface of thecover wall 22, in a cross section along the central axis of thebody 11, the contour line of theclamp ring 122 is parallel to the central axis of thebody 11. Further, in order to provide a greater error-tolerant rate, theflange 23 and a free end of thecover wall 22 are arranged at an interval. In a cross section along the central axis of thebody 11, the contour line of theflange 23 can be arc-shaped. Of course, it is conceivable that the contour line of theflange 23 can be in other shapes, too, such as wave and teeth, which can be selected according to the actual need. For a better snapping effect, the distance from the side wall of thebody 11 to theclamp ring 122 is equal to the height of the arc of theflange 23. - Compared with the prior art, the
container 10 and thecover body 20 of the snap-fitting structure of paper and plastic container provided by the present utility model have theclamping portion 12 and theflange 23 respectively. When thecover body 20 covers thecontainer 10, as the outer diameter of theclamp ring 122 is equivalent to the inner diameter of thecover wall 22, theclamp ring 122 deforms under the pressing of theflange 23. When theclamp ring 122 is beyond theflange 23, theclamp ring 122 restores to the original state or is still in a deformed state to abut against thecover wall 22, and is clamped between thecover bottom 21 and theflange 23, such that thecontainer 10 and thecover body 20 are fitted in a covering manner and are not disengaged without an external force. - The above embodiment is only a preferred embodiment of the present utility model and is not intended to limit the protection scope of the present utility model. All modifications, identical replacements and improvements made without departing from the spirit of the present utility model shall be within the protection scope of the present utility model.
