Definitions

  • the present application relates to a container for transporting goods, such as e.g. chilled or frozen goods.
  • the present application also relates to a collapsible handle-carryable grocery carrier bag. It also relates to a method for providing a collapsible carrier bag, and to a method for providing a carrier bag.
  • the present application also relates to a method of delivering goods.
  • the present application also relates to a handle-carryable grocery carrier bag package.
  • 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 from each other, to the exterior surface of one side wall of the carrier bag.
  • 2013/0315507 discloses a bag, made of paper, essentially characterized in that the handle for grabbing and transporting it is built into its own body, formed by some die cut holes.
  • the die cut holes are located at a sufficient distance from the top edge of the paper bag to allow performing some folds to close the bag in a way such that the die cut holes are just below the folds allowing for the users fingers to go through in order to grab the bag.
  • a problem to be addressed by an aspect of the invention is how to achieve an improved, yet cost-efficient, transportation of goods, e.g. grocery items, using a transport container or a carrier bag.
  • a method for providing a carrier bag comprising:
  • heating by condensation and/or frosting within the container or carrier bag is reduced or eliminated, since entry of air is reduced or prevented when the bag is closed, thereby basically rendering heat conduction through the walls the only remaining manner by which energy can seep into the interior of the container or bag.
  • 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).
  • the method further comprises the step of closing said interior storage space of said transport container or carrier bag.
  • the closing is performed in an environment having a pre-determined condition of the environment.
  • said goods comprises groceries.
  • said goods comprises drugs.
  • the loading is performed in an environment having a predetermined condition of the environment.
  • said pre-determined condition of the environment relates to the surrounding air, such as a certain relative air humidity.
  • said certain relative air humidity relates to a maximum certain relative air humidity, such as 50%.
  • said transporting is performed in a storage space having a pre-determined temperature, such as at least 10 degrees Celsius, at least 15 degrees Celsius, or at least 20 degrees Celsius.
  • said pre-determined temperature is kept for at least a predetermined time, such as for at least 5 minutes, at least 10 minutes, at least 20 minutes, at least one hour, at least two hours, at least three hours, or at least five hours.
  • said transporting is performed by a vehicle, such as a motorised vehicle.
  • the delivered goods are chilled and/or frozen goods.
  • the method further comprises putting at least one spacing layer inside said carrier bag.
  • a wall adapted to enclose an interior storage space for transporting chilled and/or frozen goods, the wall being shaped and adapted to form said interior storage space to a volume of at least ten metric litres; said wall comprising:
  • a closable opening such that the container in its closed state seals, or substantially seals, the interior storage space from the environment so as to minimize or prevent entry of air from the environment into the interior storage space;
  • said transporting step includes:
  • the wall further comprises:
  • the amount of chilled or frozen goods is at least 2 kg when the container has a volume between 10 litres and 50 litres. This advantageously provides an adequate amount of stored cold energy in relation to the container volume.
  • a container having a volume between 10 litres and 50 litres is provided.
  • the filling degree is determined so as to balance between conflicting requirements. If the filling degree is too small, the bag has too little content of chilled or frozen goods, the amount of stored negative energy is small rendering an undesiredly fast warming of the goods due the small amount of "cold energy".
  • negative energy or"cold energy are used since a piece of chilled goods having a certain temperature absorbs energy , i.e. absorbs positive energy, in the process of increasing its temperature. The absorbed energy is the energy that may seep in via the walls of the closed and sealed container, by way of heat conduction through the walls.
  • heating by condensation and/or frosting within the container 20 or bag 20 is eliminated or reduced, since entry of air is prevented or reduced as described elsewhere in this document, thereby basically rendering heat conduction through the walls the only remaining manner by which energy can seep into the interior of the container 20 or bag 20.
  • the goods may fill the interior storage space to such an extent that the chilled or frozen goods may rest close to the side walls, or even touch the side walls, thereby reducing or eliminating an insulating effect gained by a gap between the side walls and the chilled or frozen goods placed at a centre position of the bottom panel of the bag.
  • a container having a bottom panel and side panels is packed in a manner that allows an air gap to be formed between the side panels of the container and chilled or frozen goods placed at a centre position of the bottom panel.
  • a certain container is filled with goods having mutually uniform temperature. This advantageously contributes to a substantially uniform temperature throughout the goods in that container 20, and it minimizes any temperature redistribution between mutually different pieces of goods.
  • one or plural containers 20 may be packed such that a minimum number of uniform goods temperature containers are filled to the optimum filling degree.
  • each container 20 is closed and sealed, as described above.
  • closing and/or sealing of the container is performed by heat welding.
  • closing and/or sealing of the container is performed by gluing.
  • closing and/or sealing of the container is performed by use of a tape.
  • closing and/or sealing of the container is performed by clamping.
  • closing and/or sealing of the container, when the container is a bag is performed by folding a rim portion of the bag.
  • the container includes a neck portion of flexible material at the rim portion of the container wall(s), the flexible material being shaped and sized to allow a string being placed around the neck portion so as to strangle the neck portion such that the container becomes substantially sealed.
  • the container should preferably be packed and sealed such that the air trapped within the container has a relative humidity of less than 70% at an air temperature equal to the surface temperature of the goods during packing. This may advantageously minimize or eliminate the risk of condensation occurring within the container. Since the relative air humidity decreases in response to increased temperature, such relatively dry air being initially trapped in the container may not only avoid causing condensation, but it may also advantageously be able to absorb and dilute some humidity that may originate from the chilled goods or from a minor entry of ambient air during transport.
  • 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.
  • the collapsible handle-carryable kraft paper grocery carrier bag comprises a mechanical interlock which is closable such that, in the closed expanded state of the carrier bag, the mechanical interlock cooperates with said wall panels and said bottom panel so as to close and substantially seal the interior storage space from the environment so as to minimize or prevent entry of air from the environment into the interior storage space such that when a grocery package comprising frozen food is transported in said interior storage space the grocery bag is adapted to minimize or prevent the occurrence of condensation within the interior storage space.
  • 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.
  • the bag 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.
  • the grocery bag being adapted to minimize or prevent entry of air from the environment into the interior storage space advantageously contributes to maintaining the frozen or chilled state of the groceries for a significantly extended duration of time, while also preserving the integrity of the carrier bag by minimizing or preventing the formation of liquid water within the interior storage space, and by the kraft paper layer having a substantially water vapour impermeable membrane bonded to at least one side of the kraft paper layer, thereby reducing or preventing paper disintegration due to paper wetness.
