Description
- The present invention relates to a packaging means of the kind comprising an outer packaging element in the form of a box or similar in combination with at least one first thin-walled packaging element placed in the box and moulded or cast into a shape so as to contribute to support and protect an article inside the box.
- When packaging articles or sets of articles, e.g. electronical equipment, in boxes, it is common practice to support and protect the articles concerned by means of specially shaped packaging elements made of paper pulp, inserted between the article(s) and the outer box. In the case of packaging elements made from paper pulp, their method of manufacture normally sets certain limits with regard to their spatial dimensions, making them less attractive for economical reasons and for flexibility in combining various articles into a package.
- From GB 1 006 213 it is known to provide a packaging according to the preambule of claim 1, comprising an outer box-like packaging element and a thin-walled packaging element in the form of a relatively thin sheet material, which is adapted to support and protect an article inside the outer packaging element by being inserted between at least one article and the inside of the outer packaging element. Moreover, the known packaging means comprises at least one second packaging element of stock sheet material forming a wall member inside the outer box-like packaging element. The package known from GB 1 006 213 only provides limited possibilities of combining the thin sheet material with the stock sheet material.
- It is the object of the present invention to provide a packaging means of the kind referred to above, with which it is possible to bridge gaps or fill spaces between the packed object and the outer box. In many cases, the customer demands a box with fixed external dimensions. The reason may be that the box has to fulfil certain standard measures in order to be packed on the so-called Euro-pallets, i.e. the box has to have a certain modulus. There may also be other reasons for the customer demand such as traditions and sales appealing packages. Simultaneously, by filling out spaced and bridging gaps it is of course also a measure to protect the object and to obtain a safe packaging. This is obtained with packaging means made in accordance with claim 1. By combining moulded pulp or similar with a part made from cardboard, a better protection of the packed article is obtained. The moulded pulp may protect the packed article in one direction, whereas the cardboard part may protect the article in a plane perpendicular to the direction of the moulded pulp. The moulded pulp is designed to absorb energy in the said one direction in a way known per se.
- Moreover, it is by the combined package possible to guide impact forces during a drop around sensitive areas. The cardboard may also act as additional dissipation material, absorbing and dissipating the kinetic energy during drop and vibration. In addition to this, the shock absorption is also obtained by using flaps on the cardboard which co-operate with protrusions on the moulded pulp article. The cardboard can be designed to make a close fit connection with the moulded pulp inserts whereby a form-stable unit is obtained.
- It may also be possible to let the packed object exceed the horizontal boundaries of the moulded pulp. This is obtained by having a larger horizontal extension of the cardboard compared to moulded pulp pieces leaving a safety zone for displacement during shock.
- The flaps cut out from the cardboard material can according to the invention be interconnected with the moulded pulp shell in a way which avoids high shear forces at the conjunctions between moulded pulp and cardboard, because the flaps act as load distributing means at the side faces of the protrusions. Moreover, the flaps will improve the fixation of the moulded pulp pieces inside the box. The flaps also increase the bending and buckling strength, especially for those areas at which the cardboard is not closed. If the cardboard is closed on all sides, the perpendicular area of this closure acts a stiffener.
- Moreover, the flaps may cover the whole side face of the protrusions and follow the side face up to the inside of the outer box thereby assisting the moulded pulp piece in absorbing shock and vibration from the outside. A second packaging element may be cut and bent in a form permitting parts of the sheet material to be in contact with all the side surfaces of the outer box from the inside.
- Advantageous embodiments of the packaging means according to the invention, the effects of which - beyond what is obvious - are explained in the following detailed part of the present description, are set forth in claims 2-8.
- In the following detailed part of the present description, the invention will be explained in more detail with reference to the exemplary embodiments of packaging elements according to the invention shown in the drawings, in which
- Figure 1 in perspective shows a first embodiment of packaging means according to the invention,
- Figure 2 is a cross-sectional view of the embodiment of Figure 1,
- Figure 3 shows a blank made from a stock sheet material before folding a box-like structure corresponding to the box in Figures 1 and 2,
- Figure 4 in perspective shows a second embodiment of packaging means according to the invention,
- Figure 5 is a cross-sectional view through the packaging means of Figure 4,
- Figure 6 in perspective shows a third embodiment of packaging means according to the invention, and
- Figure 7 is a cross-sectional view of a fourth embodiment of the invention.
-
- The embodiment shown in Figures 1 and 2 comprises
- a box 11 made e.g. from corrugated paper or stiff cardboard,
- an
upper pulp shell 12, and - a
lower pulp shell 13. - The
pulp shells spacing box 14 cut and folded from corrugated paper or stiff cardboard, its original flat shape being shown in Figure 3. In its top and bottom walls, thespacing box 14 hasopenings 15 accommodating thepulp shells - As will be seen from Figure 2, the
pulp shells spacing box 14 through theopenings 15, being kept in place in these openings, partly bytabs 16 formed on the edge of theopening 15 in thespacing box 14 and protruding intoslots 17 formed in the side walls of thepulp shells flanges 18 formed on the pulp shells and resting against thearticle 29, and partly byflaps 19 formed in and bent outwards from the top and bottom walls of thespacing box 14. In Figure 1, thelower pulp shell 13 has been omitted; otherwise, theflange 18 on thelower pulp shell 13 would be visible. Thespacing box 14 shown in Figure 1 is closed on all sides. Thespacing box 14 is folded from the blank shown in Figure 3. - Some of the advantages of the present invention is particularly evident from Figure 2. As can be seen from this Figure, the packaging means shown can accommodate an
article 29 with a height considerably higher than the sum of the heights of the upper andlower pulp shells pulp shell - In mainly the same manner as the first embodiment described above, the embodiment shown in Figures 4 and 5 comprises
- an
outer box 21 made e.g. from corrugated paper or stiff cardboard, - an
upper pulp shell 22, - a
lower pulp shell 23, - a
box structure 24 folded from cardboard, and -
flaps 19 integral with thebox 24. - The
pulp shells box 21, they are held in place by abox 24, in the top and bottom of which there are various cut-outs and openings to fit closely about the various protrusions on the upper andlower pulp shells pulp shells box 21, so as to support and protect the article(s) (not shown) to be packaged in thebox 21. To provide good abutment between the upper andlower pulp shells flanges 28 having a width considerably greater than the thickness of the pulp shells. - The
flaps 19 are resiliently bended against the protrusions on the pulp shells. In this way, a firm fit between the shells and thebox structure 24 is obtained. This is partly due to the flaps on the sides of the protrusions, partly due to the cut-outs in thebox 24 and the guidance of the protrusions in the cut-outs. If theflaps 19 exceed to the outer box - as shown at theprotrusion 30 in Figure 4 - an improved resilient guidance is obtained. The space between thepulp shells outer box 21 may contain non-sensitive articles such as instruction manuals, video cassettes, pouches, etc. Such articles may be held in place in cut-outs in the cardboard as illustrated by theelectrical wire 31. - Figure 5 is a cross-sectional view of Figure 4, wherein the abutment between the
pulp shells cardboard box 24 inside theouter box 21 is clearly shown. - In Figure 6 is shown an embodiment mainly corresponding to the embodiment of Figure 4, however, containing four individual moulded pulp pieces 32-35 placed in cut-outs in openings (not shown) in the
spacing box 24 made from corrugated cardboard. In this way, the total dimensions of the packaging means may be extended in an almost unlimited way and independent of the dimensions of the moulded pulp pieces. The maximum dimension of the moulded pulp piece is normally given and defined by the specific moulding machine used. The products of one packaging means may consist of a number of basic elements and a number of variable elements which e.g. are dependent on the country in which they are sold. It may be considerably cheaper to exchange one individual moulded pulp piece than the whole mould. - Figure 7 illustrates a fourth embodiment by a sectional view. Once again, the outer box is designated by
reference number 21, the packed article byreference number 29 and a lower moulded pulp piece byreference number 36. The lower pulp shell is supported by acardboard element 37, which is folded from a blank with a central opening and legs extending from the plane defined by the cardboard element down to the bottom of theouter box 21. In this way, the cardboard assists thelower pulp shell 36 in absorbing loads exerted on the lower box surface. In the embodiment illustrated in Figure 7 thearticle 29 has a flat upper side and is protected inside the box by acardboard element 38 with legs extending from the upper surface of the article to the inner top surface of thebox 21. It is also probable that both top and bottom comprise a mouldedpulp piece 36 . -
