Tray pack and packaging structure

A tray pack having a first tray pack and a second tray pack, each made of an elastic thin sheet resin, engageable for suspending a product therein, the tray pack comprising:

• the first tray pack having a recessed center portion surrounded by a raised frame having an inner side with various stepped shaped members and an outer side having a multi-curved surface shape,
• the recessed center portion is a plate containing a plurality of protrusions/indentations;
• the inner side of the raised frame, adjoining the plate of the recessed center portion, contains sustaining portions for contacting the product contained in the tray pack;
• step portions, above the sustaining portions, for contacting the second tray pack;
• and engaging portions above the step portions, for engaging respective portions of the second tray pack in a tight fit due to the elastic properties of the tray pack resin;
• the outer side of the raised frame is a multi-curved surface formed of multiple curved surfaces;
• and
• the second tray pack having a recessed center portion surrounded by a raised frame having an inner side and an outer side, the outer side having sustaining portions and a multi-curved surface shape,
• the recessed center portion is a plate containing a plurality of protrusions/indentations;
• the inner side of the raised frame adjoins the plate of the recessed center portion;
• and
• the outer side of the raised frame contains sustaining portions for contacting the step portions of the first tray pack;
• and engaging portions below the sustaining portions, for engaging respective portions of the first tray pack in a tight fit due to the elastic properties of the tray pack resin;
• wherein, the first tray pack and second tray pack are faced opposed to each other so as to suspend the product securely in place via the first tray pack sustaining portions and by engaging the respective engaging portions of the first and second tray packs, formed on the frames at the perimeters of the first and second tray packs.

A packaging structure comprising:

• a tray pack having a first tray pack and a second tray pack, each made of an elastic thin sheet resin, engageable for suspending a product therein, the tray pack comprising:

• the recessed center portion is a plate containing a plurality of protrusions/indentations;
• the inner side of the raised frame, adjoining the plate of the recessed center portion, contains sustaining portions for contacting the product contained in the tray pack;
• step portions, above the sustaining portions, for contacting the second tray pack;
• and engaging portions above the step portions, for engaging respective portions of the second tray pack in a tight fit due to the elastic properties of the tray pack resin;
• the outer side of the raised frame is a multi-curved surface formed of multiple curved surfaces;
• and
• the second tray pack having a recessed center portion surrounded by a raised frame having an inner side and an outer side, the outer side having sustaining portions and a multi-curved surface shape,
• the recessed center portion is a plate containing a plurality of protrusions/indentations;
• the inner side of the raised frame adjoins the plate of the recessed center portion;
• and
• the outer side of the raised frame contains sustaining portions for contacting the step portions of the first tray pack;
• and engaging portions below the sustaining portions, for engaging respective portions of the first tray pack in a tight fit due to the elastic properties of the tray pack resin;
• and
• a box for containing said tray pack therein in a contacting relationship with flared walls formed on a bottom portion of the box;
• the box further comprising,
• a lid connected to the bottom portion;
• the bottom portion having a first set of opposing side walls having formed on each opposing side wall a flared wall opposing the flared wall of the opposite side wall;
• a second set of opposing side walls having formed on each opposing side wall a flared wall opposing the flared wall of the opposite side wall, said flared walls of the second set of opposing side walls additionally having foldable contact flaps formed thereon for contacting said tray pack;
• wherein, the first tray pack and second tray pack are faced opposed to each other so as to suspend the product securely in place via the first tray pack sustaining portions and by engaging the respective engaging portions of the first and second tray packs, formed on the frames at the perimeters of the first and second tray packs;
• and
• wherein, said tray pack is fitted into the bottom of the box contacting only the flared walls on the first and second set of opposing side walls with the contact flaps placed as to cover the upper surface of the perimeter of the second tray pack.

A portion of a tray pack having a first tray pack engageable with a second tray pack, each made of an elastic thin sheet resin, engageable for suspending a product therein, the portion of the tray pack comprising:

• the first tray pack having a recessed center portion surrounded by a raised frame having an inner side with various stepped shaped members and an outer side having a multi-curved surface shape,
• the recessed center portion is a plate containing a plurality of protrusions/indentations;
• the inner side of the raised frame, adjoining the plate of the recessed center portion, contains sustaining portions for contacting the product contained in the tray pack;
• step portions, above the sustaining portions, for contacting the second tray pack;
• and engaging portions above the step portions, for engaging respective portions of the second tray pack in a tight fit due to the elastic properties of the tray pack resin;
• and,
• the outer side of the raised frame is a multi-curved surface formed of multiple curved surfaces;
• wherein, the first tray pack and second tray pack are faced opposed to each other so as to suspend the product securely in place via the first tray pack sustaining portions and by engaging the respective engaging portions of the first and second tray packs, formed on the frames at the perimeters of the first and second tray packs.
