Definitions

  • Grocery stores are retail stores that primarily sells food.
  • a piece of grocery, or a food item, in a modern grocery store may be provided in a separate package, the size of a grocery package being adapted to contain an amount of food intended to be convenient for the customer.
  • the grocery store customer may select to purchase food by selecting a plurality of food item packages.
  • the purchasing process typically involves the customer collecting several food item packages in a physical transportation cart and the transportation of the cart to a check-out or cash register for paying. Once the customer has purchased the collected food item packages, the customer faces the problem of transporting the collected grocery items from the grocery store. Accordingly, grocery stores commonly provide carrier bags for enabling their customers to carry the groceries from the store in a convenient manner.
  • the German Utility Model Application DE 89 04 678 discloses such a carrier bag for groceries.
  • the carrier bag according to DE 89 04 678 is made solely of paper and it has handles attached to the open upper part of the side walls for enabling convenient carrying of the grocery carrier bag.
  • the production of a paper bag involves forming a tubular paper web from a planar piece of paper by placing two edges so that they overlap. The overlapping area is glued so as to form the tubular paper web. The tubular paper web is folded to form a carrier bag having four sides and a square bottom.
  • the carrier bag embodiment disclosed in DE 89 04 678 also has two handles made of reinforced paper strips. Each handle is made by a folding a paper strip to form a U-shape. The two end portions of the U-shaped handle strip of a handle are glued, at a distance a from each other, to the exterior surface of one side wall of the carrier bag.
  • a problem to be addressed by an aspect of the invention is how to achieve an improved, yet cost-efficient, transportation of grocery items using a good transportation container.
  • the step of transporting the closed kraft paper chill bag includes maintaining a closed state of the closed kraft paper chill bag during the complete transport from a goods loading room, where said kraft paper chill bag was loaded and closed, to delivery destination.
  • An embodiment comprises the step of chilling the rigid container to a predetermined temperature before the step of providing said rigid container, or chilling the second rigid container to a predetermined temperature before the step of providing said second rigid container.
  • said rigid container rigid container bottom wall and said plurality of rigid container side walls and said lid are adapted to be substantially water vapour impermeable.
  • said rigid container bottom wall and said plurality of rigid container side walls and said lid comprise an insulating layer and a layer of a material being adapted to be substantially water vapour impermeable.
  • the energy absorbent material is a material having a specific heat capacity of more than 1000 J/(kg *K); the energy absorbent material being chilled to a predetermined temperature before use of the rigid container.
  • the rigid container comprises
  • the energy absorbent material is a phase change material having a specific heat capacity and a latent heat value; the energy absorbent material being chilled to a predetermined temperature before use of the rigid container, the predetermined temperature being selected such that said phase change material is in a solid state.
  • the kraft paper chill bag is adapted to minimize energy transfer, from the air atmosphere environment to the frozen goods in the interior storage space, such that when the air atmosphere environment has a constant temperature and the product of the mass m of the frozen goods and the specific heat capacity of the frozen goods exceeds 20 000 Joule then it takes more than 4 hours to increase the mean temperature of the frozen goods by 20 K, while maintaining its frozen state, when the initial temperature difference between the warmer ambient air and frozen goods is 50K.
  • the air in the atmosphere of the earth inherently has a certain humidity.
  • the air contains a certain amount of water in vapour form.
  • the absolute humidity is the mass of water vapour per unit volume of total air and water vapour mixture. Absolute humidity in the atmosphere reaches roughly 30 grams per cubic meter when the air is saturated at 30 °C.
  • the absolute humidity in southern Sweden in the month of Juli ranged from 9 grams/cubic metre to 12 grams/cubic metre, according to the Swedish Meteorological and Hydrological Institute (SMHI).
  • any frozen grocery packages would appear to inherently cause vapour to condense into liquid water when the open carrier bag is transported in a warm air atmosphere environment having air humidity allowing such air to reach the dew point on a frozen grocery package surface. Such a condensation process may actually cause a rapid warming of the frozen grocery.
  • a carrier bag having a volume of 50 litres in the expanded state of the carrier bag, is filled by 75% with frozen groceries, there will remain about 25% of the total volume which can be filled by air in connection with the loading of the bag.
  • about 12,5 liters of air having an initial temperature of about 18 degrees Centigrade and, about 10 grams of water per cubic metre (example relating to approximate average absolute outdoor humidity in southern Sweden in the month of Juli) may be enclosed in the bag when it is sealed after packing.
  • the term "litre” means "metric litre” i.e. one litre equals one cubic decimetre.
  • the 12,5 liters of contained air may include about 0,125 grams of water in vapour form.
  • Air contained within the bag together with frozen groceries may be caused to cool, and during this decreasing of the air temperature the water vapour in that air may first condense into water, releasing 282,5 J of energy, and then it may freeze releasing 41,75 J of energy.
  • the two phase changes during the transformation of 0,125 grams of water from vapour form into ice may deliver 324 kJ.
  • the energy released may suffice to increase the temperature of 5 kg of frozen water by about 0,03 degrees, i.e. much less than half a degree Centigrade.
  • the energy released by cooling the 0,125 grams of water by 19 degrees Centigrade is comparatively small and may actually be regarded as negligible is comparison.
  • Figure 1 is a schematic illustration of an environment 10 in which embodiments of a container 20 for goods may be used.
  • the container 20 is a grocery bag 20.
  • the environment may include a grocery store 30, wherein a large number of grocery items 40 are provided.

  • a grocery store customer 60 may select to purchase food by selecting a plurality of food item packages 40.
  • the purchasing process may typically involve the customer walking through the grocery store while collecting several food item packages 40 in a physical transportation cart 70, and transporting the cart to a check-out 80, or cash register 80, for paying.
  • milk may be provided in a carton package, such as a Tetra Pak® package containing e.g. 1 litre of milk, weighing about 1 kg.
  • a carton package such as a Tetra Pak® package containing e.g. 1 litre of milk, weighing about 1 kg.

  • the cold non-freezing temperature range may be a range of about +6 to +8 degrees Centigrade.
  • the cold non-freezing temperature range may be a range of about +1 to +4 degrees Centigrade.
  • the grocery which may be collected by the customer, may also comprise frozen food packages 40, provided in a freezer within the grocery store.
  • the frozen food items 40B for delivery at a temperature of e.g. about -18 degrees Centigrade, may be collected by the customer directly from a freezer.
  • the frozen food 40B may be separately packaged e.g. in a carton box 40A.
  • the frozen food may, for example include frozen fish, meat, or vegetables.
  • the frozen food may have been frozen in a raw state, or, alternatively, it may be provided in a prepared manner such that it is ready to eat after thawing or heating.
  • some grocery goods may be provided at a freezing temperature range of about -18 degrees Centigrade, or colder.
  • the grocery store In order to achieve cost-efficient handling of the goods 40, sold in the grocery store, the grocery store typically receives a large variety of food items, each food item typically being received in bulk, i.e. an individual received food item type is received as a large number of smaller packages. As mentioned above, the smaller packages are adapted to contain an amount of packaged food 40B intended to be convenient for the customer, who typically buys just one or a few packs of each item. Similarly, it is important to provide the grocery bags 20 in bulk to the grocery store, so as to allow cost-efficiency. Accordingly, the grocery bag 20 should preferably be collapsible. The collapsible grocery bag 20 may advantageously be delivered in bulk to the grocery store, thus requiring a very small storage volume, thereby contributing to cost-efficiency.
  • the container 20 may be shaped in such a manner that plural containers 20 can be piled on top of each other in a space conservative manner.
  • An example of such a space saving shape is a cone shaped container.
  • plural cone shaped containers may be stacked by placing one cone container on top of the other such that the space required for storing ten containers is only slightly larger than the space required for storing one cone container.
  • the container may be shaped as a truncated cone such that there is provided a substantially flat bottom area inside the truncated cone container, the cone wall leaning outwardly from the bottom area.
  • the collapsed grocery bag 20A comprising kraft paper, as described below, has a balanced rigidity and flexibility allowing it to be easily expanded.
  • the carrier bag In its expanded state 20C the carrier bag provides an interior storage space which is sufficiently large for transporting a plurality of grocery packages, even when the individual grocery packages are larger than 1 litre.

  • the carrier bag may further comprise a first handle 170A being associated with said rim portion 150, 150A of said front wall panel S1A.
  • the first handle 170A may be shaped and dimensioned to allow gripping by a human hand such as to enable convenient carrying of the grocery carrier bag. In some businesses where carrier bags are utilized, it is considered necessary for a carrier bag to be provided with a handle, since a handle-carryable grocery carrier bag is considered to be a fundamental customer convenience requirement.
  • a grocery bag which is capable of being carried by means of a handle, or a pair of handles, is considered to be a fundamental customer convenience requirement.
  • the carrier bag is therefore advantageously provided with an integrated handle, or an integrated pair of handles such that a handle-carryable grocery carrier bag is supplied.

  • An increased surface weight of the kraft paper in combination with a lower density leads to a yet a further increase of the internal thermal resistance of the kraft paper wall.
  • the kraft paper may be as low as 350 kg/m 3 .
  • the inventors also cocluded that, it is preferable to select a kraft paper density higher than 350 kg/m 3 and surface weight higher than 60 grams per square meter.

This may be due e.g. to the folded portions forming fissures or slits through which a fluid, such as air, may pass between the environment and the interior storage space of the bag.
  • the entry of air having a certain air humidity may cause liquid water to be formed on a cold surface, such as on a surface of chilled goods in the interior storage space of the carrier bag.

  • the cover sheet 700 is sized and adapted to fit snugly on the interior surface of the bag bottom panel BP so that it covers any paper edges from the bag bottom panel BP on the interior surface.
  • the edges can give cause to small openings through which air and thus heat can pass. Although being generally small, these openings might contribute greatly to the total amount of heat transferred from the outside of the cag to the interior of the bag.
  • heat transfer from the outside of the transport container/carrier bag through the bottom portion BP to the inside of the bag, or vice versa is reduced.
  • the cover sheet by covering the edges, can reduce this heat transfer.
  • the edges in the bottom portion BP are in general at a distance from the perimeter, or from the outer lines, of the bottom portion BP. Thus, by covering the bottom portion BP, the edges are generally well covered as well.
  • Placing the cover sheet 700 in the interior storage space of the bag may, however, require that the bag is available in an expanded position in order to make it possible to reach the bottom panel at the inside of the bag. Depending on how the bag is manufactured, this might require an extra step and/or might cause problems to reach the inner bottom panel BP from the inside due to the design of the bag.

  • cover sheet 700 Another advantage of the cover sheet 700 is that vaporous transfer and/or transfer of liquids through the bottom side of the transport container/carrier bag may be reduced. This is due to the fact that the bottom of the transport container/carrier bag will contain at least one additional layer due to the cover sheet 700. Each additional layer will prolong the time before liquid/vapour will be able to pass through the bottom side of the transport container/carrier bag. This will prolong the time before the material of the bottom portion BP and/or the cover sheet 700 will lose its bearing strength due to absorbed liquid/vapour. Other advantages of different layer configurations for the cover sheet 700 have been described elsewhere in this document.
  • Said cover sheet 700 can be attached to the inside and/or the outside of the transport container/carrier bag. Attaching the cover sheet 700 to the outside can be easier when providing the improved transport container since the outside often is available when the transport container/carrier bag is provided, see for example, Fig. 40M . Attaching the cover sheet to the inside of the transport container/carrier bag is advantageous if edges of the bottom portion BP are folded to the inside of the transport container/carrier bag. This situation is illustrated in Fig. 29a and Fig. 29b . There, for not overloading the figure, only the bottom portion BP of a transport container/carrier bag is depicted.

  • the cover sheet 700 is advantageous to put the cover sheet 700 on the inside/outside of the transport container/carrier bag if it is expected that the liquid/vapour will preferably transmit from the inside to the outside of the transport container/carrier bag, or vice versa, respectively.
  • the cover sheet 700 comprises said at least one layer for preventing, or at least reducing transfer of liquid and/or vapour through the cover sheet 700.
