Abstract

A lid body for a wet wipes package includes a frame and a lid. The frame has a frame opening surrounding a body opening. The lid is pivotally coupled to the frame via a hinge section to cover the frame opening from the front surface. The frame has a mating member peripherally disposed thereon and protruding from the surface. The mating member includes an internal wall, an external wall and a groove defined therebetween. The lid has the projection peripherally disposed thereon and protruding from the rear surface of the lid to be fitted into the groove. A distance between the projection and the hinge section at a position with the shortest distance between the frame opening and the hinge section is at least five times an overlapping height between the projection and the mating member.

First claim

The invention claimed is:

1. A lid body for a wet wipes package to be attached to a bag body of the wet wipes package, the lid body comprising:
a frame having a frame opening which is arranged to surround a bag opening formed on a top surface of the bag body in a state in which the lid body is attached to the bag body, wherein the frame has a shape defined by a first edge, a second edge opposite the first edge, a third edge adjacent to the first edge and the second edge, and a fourth edge opposite the third edge; and
a lid pivotally coupled to the first edge of the frame via a hinge section and which is arranged to block the frame opening from a top side of the frame when the lid is in a closed state, wherein the top side of the frame faces a bottom side of the lid when the lid is in the closed state;
wherein:
one of the frame and the lid has a projection peripherally disposed thereon and protruding from the bottom side of the lid or the top side of the frame,
the other of the frame and the lid has a mating member peripherally disposed thereon and protruding from the bottom side of the lid or the top side of the frame, the mating member being engageable with the projection,
the mating member includes an internal wall, an external wall, and a groove defined therebetween,
the internal wall has an upper end bent inward to define a guide which guides the projection to be fitted into the groove,
the external wall has a first notch at a position which substantially corresponds to a longitudinal center of the first edge, and a second notch at a position which substantially corresponds to a longitudinal center of the second edge,
a distance between the projection and an outer edge of the hinge section at a position with a shortest distance between the frame opening and the hinge section is at least five times an overlapping height between the projection and the mating member when the lid is in the closed state,
the overlapping height is a height of an overlapped portion of the projection and the mating member,
the overlapping height is at least 1.5 mm,
the overlapped portion is defined such that, at the overlapped portion, the projection is in close contact with the mating member at least at its tip and is in contact with the mating member with a clearance of 0.2 mm or less at all portions other than the tip, and
the position with the shortest distance between the frame opening and the hinge section coincides with the position of the first notch in the external wall.

2. The lid body for the wet wipes package according to claim 1 , further comprising:
a tab disposed on a second edge of the lid which is opposite a first edge of the lid where the hinge section is connected;
a locking part disposed on the second edge of the frame opposite the first edge of the frame where the hinge section is connected, the locking part being engageable with the tab; and
push tabs disposed on the second edge of the frame, the push tabs each being disposed on respective sides of the locking part along the second edge of the frame.

3. The lid body for the wet wipes package according to claim 1 , wherein a first area surrounded by the projection or the mating member peripherally disposed on the lid has higher rigidity than a second area outside of the first area surrounded by the projection or the mating member of the lid.

4. A wet wipes package comprising:
a bag that includes a bag body having a body opening on a top surface thereof and a flap covering the body opening in a freely openable and closable manner; and
the lid body for the wet wipes package according to claim 1 ,
wherein the lid body is attached to the top surface of the bag body.

5. The lid body for the wet wipes package according to claim 1 , wherein the distance between the projection and the outer edge of the hinge section at the position with the shortest distance between the frame opening and the hinge section is at least ten times the overlapping height between the projection and the mating member when the lid is in the closed state.
