Description

A Cushioning Article
The invention relates to a cushioning article.
According to the invention there is provided a cushioning article comprising a series of inflatable compartments and a gallery leading to the compartments, and an inflation entry point communicating with the gallery and at which a pump can be used to inflate the compartments, the article including one way means so that the compartments do not deflate once inflated, the article further including at least one adhesive area covered by a backing sheet.
In this way, the article can be inflated using a pump, and the inflated article can then be attached to an object to provide protection.
The or each adhesive area may be on a flap extending from the inflated compartments.
The adhesive may be of any suitable type and may be a peelable adhesive, or a permanent adhesive. Where the adhesive is a permanent adhesive, a line of weakness may be defined in the flap between the adhesive area or areas and the compartments so that the part of the article with the compartments can be tom off.
The or each adhesive area may be an elongate strip.
The one way means may comprise a one way valve for each compartment.
The compartments may be any suitable shape, but preferably are elongate
The article is conveniently made from a section cut from a ribbon of material with a repeating pattern along the ribbon forming the compartments and gallery.
The article may be made of plastics material, such as polyethylene. The article preferably includes a barrier layer, which may be made of polyamide.
The article is suitably made from a sheet in which each compartment is a two layer construction. Each layer of plastics sheet material may be in the range of 20 to 110 microns thick.
Embodiments of the invention will now be described by way of example and with reference to the accompanying drawings.
Figure 1 is a plan view of a sheet for making an article in a first embodiment of the invention;
Figure 2 is a perspective view of the sheet of Figure 1 when inflated;
Figure 3 is a side elevation of the cushion inflated from the sheet of Fig 1 in an arrangement between two vehicle seats;
Figure 4 is a plan view of a sheet for making a cushion in a second embodiment of the invention;
Figure 5 is a side elevation of a seat of the arrangement of the second embodiment after removal of the cushion;
Figure 6 is a plan view of a sheet according to a third embodiment of the invention when folded and sealed, but not inflated;
Figure 7 is a perspective view of the inflated bag of Fig 6; and Figure 8 is the view of Figure 7 with the bag closed.
Figures 1 and 2 show a sheet 10 of a first embodiment of the invention. The sheet 10 comprises two layers which are partially heat sealed together. Each layer comprises polyethylene with a barrier layer of polyamide to better resist air leakage. Looking at Figure 1, in each place where there are double lines, the two layers are heat sealed together in the areas between the double lines. Thus, looking at the rectangular sheet 10 in the orientation shown in Figure 1, it is seen that the sheet 10 has been cut from a longer ribbon of material which contains the same repeating pattern of heat sealing along its length from left to right. There is a heat seal line 12 adjacent the top edge in the sheet 10 and a heat seal line 14 adjacent the lower edge of the sheet. Adjacent the upper heat seal line 12 is a further heat seal line 16. The heat seal lines 12 and 16 at the top edge define a tubular gallery 18 between them. Spaced from the right hand end of the sheet is a perpendicular seal line 20 to seal the end of the gallery 18. A rigid polyethylene nozzle 22 is fitted into the opposite end of the gallery 18 through which air can be introduced into the gallery 18. The region between the heat seal lines 14, 16 is divided into compartments 26 by perpendicular heat seal lines 24.
At the region just below the seal line 16 bounding the lower edge of the gallery 18, there is a further thickness of plastic material 28. This additional layer of plastic material 28 is heat sealed to the upper layer of the sheet 10 in a particular pattern 30 which is repeated at regular intervals along the sheet 10 so that there are three such patterns 30 for each compartment 26. The heat seal line 16 which is the lower bound of the gallery 18 is broken at the entrance to each pattern 30 so that air can pass between the additional sheet 28 and the upper layer of the sheet 10. This forms an opening 32 for air to pass from the gallery 18 into the compartment 26. From the opening 32 two straight lines 34 of heat seal are provided which converge towards one another without meeting. Facing the gap between the ends of the heat seal lines 34 is a triangle 36 of heat sealing, with one apex facing the ends of the lines 34. Behind the triangle 36 is a short heat seal line 38 which is elongate in the direction away from the triangle 36. On each side of the short line 38 is a short lateral line 40, one behind each rear apex of the triangular heat seal 36. Behind the three short lines 38, 40 is a line of heat seal dots 42.
This pattern 30 forms a one way valve so that air can enter the compartment 26 through the opening 32 and between the additional layer 28 and the upper layer of the sheet 10, but cannot escape backwards out of the compartment 26.
Beyond the right hand end of the last perpendicular heat seal 24 is a part of the sheet 10 which is not bounded by heat seal lines and hence cannot be inflated. This part of the sheet 10 forms a flap 37. At the free end of the sheet 10 is a strip of peelable adhesive 39 covered by a backing strip 41. The strip of adhesive 39 extends from close to one side to close to the other side of the sheet 10 in other words it extends over substantially the whole width of the sheet 10.
Fig 2 shows the sheet 10 of Fig 1 when it has been inflated by using a pump (not shown) to pump air into the sheet 10 through the nozzle 22 to form a cushion.
Fig 3 shows an arrangement according to the invention in which the cushion 10 is between two car seats 50, 52 on a production line. Each seat has a back 54, 56, and squab 58, 60 and a frame 62, 64 under the squab 58, 60. The cushion 10 is placed on the squab 58 of the lower seat 50, and the backing sheet 41 is removed from the adhesive strip 39, and the flap 37 is pressed onto the upper surface 66 of the squab 58 of the lower seat 50 to attach it. The upper seat 52 is then placed onto the cushion 10, with the frame 64 of the upper seat in contact with the cushion, and the back 56 of the upper seat 52 resting against the back 56 of the lower seat 50. The cushion is large enough that all of the frame 64 rests on the cushion 10 and none on the squab 58 of the lower seat 50. The cushion 10 may be about 400x400mm in plan and each compartment may be about 40mm tall when inflated. Each compartment 26 when uninflated may be 90mm wide and 350mm long. Each of the two layers of the sheet may be 90 microns thick.
The cushion 10 acts to protect the lower seat 50 from potential damage by the frame 64 of the upper seat 52, for example from scratching or tearing, either during placement of the upper seat 52 on the lower seat 50, or while being moved on the production line, or when the upper seat 52 is taken off the lower seat 50.
When the upper seat 52 has been removed, the cushion can be removed by peeling it off as the adhesive is a peelable adhesive.
The uninflated sheets 10 are light and compact to store before use It is quick to inflate and apply the cushion, which is then held in place by the adhesive.
Figs 4 and 5 show a second embodiment. In the second embodiment, the adhesive of the adhesive strip 39 is a permanent adhesive, and the squab 58, 60 and back 54, 56 of each seat 50, 52 is covered with a cover 68 of plastics material sheet. The flap 37 includes a line of perforations 70 across the full width of the sheet 10 parallel to the axes of the compartments 26.
In the second embodiment, when the cushion is placed on the squab 58 of the lower seat 50, the backing sheet 41 is removed and the flap 37 is pressed against the cover 68 of the lower seat 50 to hold it in place. When the upper seat 52 has been removed, the cushion can be tom along the line of perforations 70 to leave just the part 72 of the flap beyond the line of perforations 70 still attached to the cover 68. When a car with the seats 50, 52 fitted is received in a showroom, the covers 68 will still be on the seats 50, 52 for protection, and the presence of the tom off part 72, still adhered to the cover 68 provides evidence that the seats 50, 52 were properly protected.
Figures 6, 7 and 8 show a larger version of the sheet 10 formed into a bag. Fig 6 shows the bag uninflated. The sheet 10 has been folded in two, at a fold line along the right hand side 144, and the two halves have been heat sealed together along the lower edge at line 146, and up the left hand side from the lower line 146 to just over half way up, at line 148, just outside the gallery 18. As shown in Fig 4, a portion of the top of the rear half of the folded sheet is cut away. To form the inflated top 150, a further heat seal line 152 is put in in the top half of the sheet opposite the gallery 18. The cut away would otherwise mean that this part would be open to atmosphere and would not inflate. The shaded area in Fig 3 shows the part 154 of the sheet 10 which will not inflate. The gallery 18 is open at the top end rather than including a nozzle 22, so a pump is inserted into the open end 156 of the gallery 18 to inflate the compartments 26. In each half, adjacent each side edge there is a line of constrictions 158, 160. Each constriction is a partial heat seal limiting the air flow at that part of the compartment 26.
Figs 7 and 8 show the inflated bag 162. It is seen that the lines of constrictions 158, 160 become fold lines, so that the bag assumes a rectangular shape in plan with the bag body 180 defining a cavity 184. The uninflated part 154 comprises a flap 164 projecting upwards from the top 150, and wings 166, 168 to either side which are connected to the flap 164, top 150 and inflated side walls 170. The flap 164 includes an area of adhesive 172 in the form of a strip across most of the width of the flap 164. The area of adhesive 172 is covered by a backing sheet 174.
Figs 7 and 8 show in phantom two bottles 176, 178 placed inside the cavity 184 of the bag body 180. To close the bag 162, the backing sheet 174 is removed from the strip of adhesive 172, and the flap 164 is pulled down and pressed against the front wall 182 of the bag body 180 to stick to it. The top 150 will then cover the open top of the bag body 180. In this form, the bottles 176, 178 can be sent through the post.
In a variation on the embodiment, a line of perforations is provided across the uninflated part 154 below the adhesive strip 172, so that the bag can be opened by tearing the line of perforations. Thus, part of the flap 164 will be left attached to the front of the bag, but the top 150 will be released to be opened.
