The stackable plastic container is primarily characterized by a bottom portion, a top portion, a front wall and a back wall and two side walls forming a parallelepiped, the parallelepiped having rounded corners and edges with a mold center plane dividing the parallelepiped through the front wall, the back wall, the top portion and the bottom portion; a handle protruding upwardly from the top portion; a filling and pouring socket protruding upwardly from the top portion in an area adjacent to the front wall, the filling and pouring socket having a shoulder where the top portion and the filling and pouring socket meet; a cap for closing the filling and pouring socket; a U-shaped stacking surface protruding upwardly from the top portion and surrounding the handle, the stacking surface having a planar contact surface for receiving thereon a further identical collapsible plastic container, the U-shaped stacking surface comprising legs extending parallel to the mold center plane and a stacking shoulder connecting the legs and being arranged opposite the filling and pouring socket; and sloped inwardly curved surface areas extending from free ends of the legs in a downward slope toward lateral portions of the front wall adjacent to the side walls to an elevation below the shoulder and extending in an upward slope from the lateral portions to the shoulder of the pouring socket. The sloped inwardly curved surface areas extending from free ends of the legs each have a generally flat downwardly sloping portion extending toward a transition area where the front wall and the side wall merge together, the transition area being at an elevation below the forward shoulder, and a portion curving upwardly from the transition area to the forward shoulder.

It is expedient that the sloped inwardly curved surface area essentially form a plane within a section extending between the legs and the top portion. Preferably, the plane of the sloped inwardly curved surface areas, in the section between the legs and the top portion, extends approximately vertically. In a preferred embodiment, the plane extends at an acute angle relative to the mold center plane toward the filling and pouring socket. In another preferred embodiment, the plane extends at an obtuse angle relative to the mold center plane toward a respective one of the side walls.

It is advantageous that the filling and pouring socket be forwardly positioned such that it protrudes relative to a vertical extension of the front wall, the front wall having a bulge to form a transition to the filling and pouring socket, the legs of the stacking surface being respectively forwardly elongated.

It is furthermore expedient that a top surface of the cap, when in a closing position, is located in a same plane with the stacking surface.

For many years, large wooden pallets were used in shipping products from one place to another by air, sea, railways, and on the highway. Recently, many companies have made the shift from wooden pallets to plastic pallets, a decision that is based on sound reasoning at various levels of concern. In this article, we will take a look at why plastic pallets are superior to wooden pallets when it comes to transportation of goods.
  Durability
  One of the most important advantages of a plastic pallet is the durability of the  material over wood. This benefits the both shipper and receiver in a number of areas.
Plastic pallets won't splinter. Wood pallets are prone to splintering during shipping. These splinters can be messy and may even create a safety hazard for handlers. Perhaps even more important, splinters have the potential to damage the goods for which the pallets are supposed to be protecting. Plastic is a highly cohesive material that is unlikely to chip during even rough transport, with no chance of large splinters     breaking off.
  Cost efficient. Of course, the more durable a pallet is, the more money saved by the shipper or receiver. Wooden pallets are much more likely to break apart sooner than plastic pallets; a plastic pallet can conceivably be used for years before it has to be replaced, if it ever does.
  Flexibility
  In addition to their durability, plastic pallets also have the advantage of accommodating different types of goods within the same pallet. Most plastic pallets will include dividers of various sizes, allowing the pallet to be adapted to the goods that one wishes to ship or receive.
  The flexibility of plastic pallets may also mean savings when it comes to transportation costs. Wooden pallets must be stacked in a certain way once emptied; plastic pallets, on the other hand, can be collapsed and fit into a much smaller space. This means that less room is used on the transport vehicle, resulting in lower costs and fewer trips.
  Finally, consider the environmental impact of plastic and wood. While it is true that plastic will break down at a much slower rate, this simply means that a plastic pallet will be used for a much longer period of time (in fact, much, much longer). The continual construction of replacement wooden pallets is much more harmful to the environment than plastic pallets, which can not only be used over and over for years, but they also have the potential to be recycled, and be made from recycled materials.

Over the past thirty years, corrugated plastic pipe has proven itself to be a strong, chemically inert, viable pipe for use in applications around the world.

Corrugated polyethylene pipe has been used successfully for decades in a variety of drainage applications. The specification and use of corrugated pipe is skyrocketing based on important advantages such as enhanced hydraulic flow and unparalleled chemical and abrasion resistance when measured against other materials. Corrugated polyethylene pipe is also easy to install and is environmentally friendly.

PIPE CHARACTERISTICS:

1 HDPE drainage pipe offers all the chemical and physical advantages of other HDPE pipes.

2 Corrosion resistance. Does not rust, rot or corrode.

3 High strain allowances. Virtually eliminates breakage.

4 No infiltration or ex-filtration.

5 Lightweight and longer lengths allow for significant saving in labor and equipment.
