Definitions
- the present disclosure is broadly concerned with an adapter for use with a postal envelope tray. More particularly, it is concerned with an adapter for supporting and protecting a horizontal stack of envelopes within a postal tray to maintain the envelopes in a compressed, flattened state during curing of the adhesive and at the same time permit vertical stacking of additional postal trays in a nesting relation without deforming the envelopes.
- Envelopes used for bulk mailing are generally obtained in quantity from an envelope manufacturer and delivered to inserter/mailer firms that use automated equipment to stuff the envelopes.
- envelopes reach the exit tray or table of the envelope machine with the side seam adhesive still wet.
- the envelopes are immediately removed by hand under compression and tightly packed into corrugated cartons. Because the packed envelopes are compressed, the panels are held together until the adhesive cures and the envelopes dry in a flat state.
- the cartons of envelopes are then delivered to an inserter firm, opened and the envelopes are unloaded by hand for placement into the inserter apparatus.
- the “stuffed” envelopes are then placed in containers such as postal trays and delivered to a bulk mail center or postal facility.
- corrugated cartons are expensive, difficult to handle and open and they take up space in the area of the envelope and inserter machinery. They also present disposal problems for the inserter firm. Attempts to reuse the cartons have been unsuccessful because of the labor required to sort and handle them.
- the trays are manufactured in accordance with USPS specifications to include a flat rectangular base and four upwardly and outwardly extending sides, each having the shape of an isosceles trapezoid, so that all sides extend upwardly and outwardly at an angle from the base.
- the trays are sized to receive a horizontally stacked layer of stuffed, standard sized business envelopes that are upstanding in orthogonal relation to the base of the tray. Because of the outward angle of the sides there is a gap between the sides of the tray and the sides of the envelope stack.
- the gap resulting from that configuration prevents lateral support of the envelope stack.
- the angular gap between the outwardly angled sides of the tray and the orthogonal envelope stack provides room for the envelopes to curl and warp.
- Newly manufactured envelopes are particularly susceptible to distortion or deforming as the wet adhesive cures. Such deformed envelopes are unsuitable for use with automatic inserting equipment because of their tendency to jam the equipment. Without the necessary pressure to hold the envelopes tightly together, the panels may also separate from each other before the adhesive is dried, causing the seams to become unglued and rendering the envelopes unusable.
- the sides of the trays are configured to enable close stacking of the trays when they are not in use, they do not keep the bottom of a stacked tray up and away from the top of a horizontal stack of envelopes in a lower tray. This may result in crushing of envelopes when the postal trays are vertically stacked in a column.
- the envelope tray adapter provides a greatly improved system for protecting a horizontal stack of envelopes positioned in a postal tray having outwardly angled sidewalls.
- the adapter has pairs of side and end panels joined end to end and sized to fit on the bottom wall of the postal tray. Each panel has a height greater than the height of the envelope stack, but less than the sidewalls of the postal tray in order to support a second postal tray nested on top and protect the envelopes from being crushed.
- the panels may be formed from a continuous length of any suitable material that is folded to form the side and end panels and is strong enough to support the load produced.
- Appropriate materials include common corrugated paper box forming product known as “275 pound test paper board.”
- One end of the panels has a free end including a glue flap that overlaps and adheres to the inner surface of the adjacent end panel.
- An envelope packaging system for stacks of horizontal envelopes includes a postal tray with an envelope tray adapter positioned in engagement with the bottom wall of the postal tray to receive a horizontal stack of envelopes and a second postal tray positioned atop the envelope tray adapter to maintain the second postal tray out of engagement with the envelopes.

Abstract
An envelope tray adapter is designed to protect a horizontal stack of envelopes positioned in a postal tray having outwardly angled sidewalls. The adapter has pairs of side and end panels joined end to end and sized to fit on the bottom wall of the tray. Each panel has a height greater than the envelope stack, but less than the sidewalls of the tray for supporting a second postal tray nested on top and protecting the envelopes from crushing. The panels may be formed from a continuous length of material that is folded to form the end and side panels. The adapter panels may also be formed of a corrugated paper material. One end of the panels has a free end including a glue flap that overlaps and adheres to the inner surface of the adjacent panel.
Description
- The present disclosure is broadly concerned with an adapter for use with a postal envelope tray. More particularly, it is concerned with an adapter for supporting and protecting a horizontal stack of envelopes within a postal tray to maintain the envelopes in a compressed, flattened state during curing of the adhesive and at the same time permit vertical stacking of additional postal trays in a nesting relation without deforming the envelopes.
- Envelopes used for bulk mailing are generally obtained in quantity from an envelope manufacturer and delivered to inserter/mailer firms that use automated equipment to stuff the envelopes. Typically, envelopes reach the exit tray or table of the envelope machine with the side seam adhesive still wet. The envelopes are immediately removed by hand under compression and tightly packed into corrugated cartons. Because the packed envelopes are compressed, the panels are held together until the adhesive cures and the envelopes dry in a flat state. The cartons of envelopes are then delivered to an inserter firm, opened and the envelopes are unloaded by hand for placement into the inserter apparatus. The “stuffed” envelopes are then placed in containers such as postal trays and delivered to a bulk mail center or postal facility.
- This packaging system is expensive, inefficient and not environmentally friendly. The corrugated cartons are expensive, difficult to handle and open and they take up space in the area of the envelope and inserter machinery. They also present disposal problems for the inserter firm. Attempts to reuse the cartons have been unsuccessful because of the labor required to sort and handle them.
- While it would be preferable to transport the newly manufactured envelopes to the inserter/mailer in postal trays, which could be reused to deliver the stuffed envelopes for mailing, previous attempts to do so have not been successful. This failure may be attributed to the configuration of US postal trays. The trays are manufactured in accordance with USPS specifications to include a flat rectangular base and four upwardly and outwardly extending sides, each having the shape of an isosceles trapezoid, so that all sides extend upwardly and outwardly at an angle from the base. The trays are sized to receive a horizontally stacked layer of stuffed, standard sized business envelopes that are upstanding in orthogonal relation to the base of the tray. Because of the outward angle of the sides there is a gap between the sides of the tray and the sides of the envelope stack.
- While the outwardly angled configuration of the sides of the trays advantageously enables the trays to be stacked in a nested fashion, the gap resulting from that configuration prevents lateral support of the envelope stack. The angular gap between the outwardly angled sides of the tray and the orthogonal envelope stack provides room for the envelopes to curl and warp. Newly manufactured envelopes are particularly susceptible to distortion or deforming as the wet adhesive cures. Such deformed envelopes are unsuitable for use with automatic inserting equipment because of their tendency to jam the equipment. Without the necessary pressure to hold the envelopes tightly together, the panels may also separate from each other before the adhesive is dried, causing the seams to become unglued and rendering the envelopes unusable.
- In addition, while the sides of the trays are configured to enable close stacking of the trays when they are not in use, they do not keep the bottom of a stacked tray up and away from the top of a horizontal stack of envelopes in a lower tray. This may result in crushing of envelopes when the postal trays are vertically stacked in a column.
- Accordingly, there is a need for an envelope packaging system that avoids the problems previously described and permits usage of USPS postal trays to transport newly manufactured envelopes throughout the mailstream and that permits the trays to be stacked without crushing the envelopes,
- The envelope tray adapter provides a greatly improved system for protecting a horizontal stack of envelopes positioned in a postal tray having outwardly angled sidewalls. The adapter has pairs of side and end panels joined end to end and sized to fit on the bottom wall of the postal tray. Each panel has a height greater than the height of the envelope stack, but less than the sidewalls of the postal tray in order to support a second postal tray nested on top and protect the envelopes from being crushed. The panels may be formed from a continuous length of any suitable material that is folded to form the side and end panels and is strong enough to support the load produced. Appropriate materials include common corrugated paper box forming product known as “275 pound test paper board.” One end of the panels has a free end including a glue flap that overlaps and adheres to the inner surface of the adjacent end panel. An envelope packaging system for stacks of horizontal envelopes includes a postal tray with an envelope tray adapter positioned in engagement with the bottom wall of the postal tray to receive a horizontal stack of envelopes and a second postal tray positioned atop the envelope tray adapter to maintain the second postal tray out of engagement with the envelopes.
- Various objects and advantages of this envelope tray adapter will become apparent from the following description taken in conjunction with the accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of this invention.
- The drawings constitute a part of this specification, include exemplary embodiments of the envelope tray adapter, and illustrate various objects and features thereof.
