The present disclosure relates to a container for consumer goods, the container comprising a sealed compartment and an access region comprising an unsealed area. The present disclosure also relates to a method of manufacturing a packaged aerosol-generating article.
It is known to package consumer goods in containers comprising two layers of material overlying each other to form a compartment in which the consumer goods are positioned. In some examples, the two layers of material may be sealed to each other to form a sealed compartment in which the consumer goods are positioned. To open the sealed container, it may be necessary to peel one of the layers of material away from the other layer of material. It is desirable to make a container that is easy to open for a consumer. However, it is also desirable to make a container that reduces the risk of the container being opened accidentally. Typically, providing a container that is difficult to open accidentally but easy to open when desired is challenging.
According to a first aspect of the present disclosure there is provided a container for consumer goods, the container comprising a first substrate layer and a second substrate layer overlying the first substrate layer. A first portion of the first substrate layer and a first portion of the second substrate layer form a compartment region, wherein a perimeter of the compartment region is completely sealed to form a sealed compartment for containing one or more consumer goods. A second portion of the first substrate layer and a second portion of the second substrate layer form an access region directly adjacent to the compartment region. The access region comprises an unsealed area, wherein a perimeter of the access region extends around the unsealed area. The first substrate layer is attached to the second substrate layer at the perimeter of the access region. The unsealed area is separated from the sealed compartment by the completely sealed perimeter of the compartment region. The container further comprises a line of weakness extending at least partially within the unsealed area of the access region.
As used herein, the term “sealed” refers to a portion of the container at which the first substrate layer is secured to the second substrate layer. When referring to a perimeter of a region of the container, the term “completely sealed” refers to a perimeter that is sealed along 100 percent of the length of the perimeter.
As used herein, the term “directly adjacent” is used to refer to a first portion of the container being adjacent to a second portion of the container without any intervening portions of the container being positioned between the first portion and the second portion. The access region is directly adjacent to the compartment region.
For ease of reference, the perimeter of the access region may be herein referred to as the “access region perimeter”. The perimeter of the compartment region may be herein referred to as the “compartment region perimeter”.
Advantageously, the unsealed area of the access region facilitates opening of the container by a user. For example, after breaking the line of weakness in the unsealed area, a user may grasp the first substrate layer at the unsealed area with one hand and grasp the second substrate layer at the unsealed area with the other hand, then peel the first substrate layer away from the second substrate layer along at least part of the completely sealed compartment region perimeter.
Advantageously, the attachment of the first substrate layer to the second substrate layer at the perimeter of the access region may reduce the risk of accidental opening of the container, or prevent accidental opening of the container. For example, the attachment of the first substrate layer to the second substrate layer at the access region perimeter may prevent a user from separately grasping the first substrate layer and the second substrate layer at the unsealed area.
Advantageously, providing a line of weakness extending at least partially within the unsealed area may facilitate a user opening the container when desired. For example, by breaking at least one of the first substrate layer and the second substrate layer along the line of weakness in the unsealed area may allow a user to separately grasp the first substrate layer and the second substrate layer at the unsealed area.
The unsealed area may be separated from the sealed compartment by the completely sealed perimeter of the compartment region and the perimeter of the access region.
The line of weakness may be in only one of the first substrate layer and the second substrate layer. Advantageously, providing the line of weakness in only one of the first substrate layer and the second substrate layer may facilitate the container remaining as a single piece when the first substrate layer or the second substrate layer is broken along the line of weakness. Advantageously, this may reduce or prevent littering by minimising the number of pieces of the container to be discarded by a user when the container has been opened and is no longer required. For example, in embodiments in which the line of weakness is in the first substrate layer only, even if the first substrate layer is broken into two pieces when the container is broken along the line of weakness, the two pieces of the first substrate layer may remain attached to the single second substrate layer by the completely sealed compartment region perimeter and the access region perimeter.
The line of weakness may be in both the first substrate layer and the second substrate layer. Advantageously, providing the line of weakness in both the first substrate layer and the second substrate layer may facilitate breaking of both the first substrate layer and the second substrate layer in the unsealed area. Advantageously, breaking both the first substrate layer and the second substrate layer may facilitate a user separately grasping the first substrate layer and the second substrate layer at the unsealed area.
The line of weakness may extend between a first edge of the container and a second edge of the container.
Advantageously, the line of weakness extending between the first edge of the container and the second edge of the container may facilitate a user breaking at least one of the first substrate layer and the second substrate layer along the line of weakness. For example, starting from the first edge of the first substrate layer or the second edge of the first substrate layer, a user may tear or otherwise break at least one of the first substrate layer and the second substrate layer along the line of weakness.
Advantageously, the line of weakness extending between the first edge of the container and the second edge of the container may facilitate detachment of a part of the container comprising a part of the unsealed area of the access region when the container is broken along the line of weakness. Advantageously, detaching a part of the container comprising a part of the unsealed area may facilitate a user separately grasping the first substrate layer and the second substrate layer at the remaining part of the unsealed area of the access region.
The perimeter of the access region may comprise at least one unsealed portion, wherein the line of weakness extends across the at least one unsealed portion. Advantageously, the at least one unsealed portion may facilitate a user separately grasping the first substrate layer and the second substrate layer at the perimeter of the access region once the container has been broken along the line of weakness. Advantageously, the at least one unsealed portion may be positioned at an edge of the container. Advantageously, positioning the at least one unsealed portion at an edge of the container may facilitate a user separately grasping the first substrate layer and the second substrate layer at an edge of the container once the container has been broken along the line of weakness. Advantageously, separately grasping the first substrate layer and the second substrate layer at an edge of the container may reduce a force required to separate the first substrate layer from the second substrate layer along the sealed compartment region perimeter when opening the container.
The at least one unsealed portion may comprise a first unsealed portion and a second unsealed portion, wherein a first end of the line of weakness extends across the first unsealed portion and wherein a second end of the line of weakness extends across the second unsealed portion. Advantageously, this configuration may further facilitate a user separately grasping the first substrate layer and the second substrate layer at the access region once the container has been broken along the line of weakness. The first unsealed portion, the second unsealed portion and the unsealed area of the access region may extend continuously between a first edge of the container and a second edge of the container.
The line of weakness may extend across a part of the sealed perimeter of the compartment region. Advantageously, the line of weakness extending across part of the sealed perimeter of the compartment region may facilitate opening of the compartment region when a user breaks the container along the line of weakness. In other words, the line of weakness extending across part of the sealed compartment region perimeter may facilitate a user separating the first substrate layer from the second substrate layer across at least part of the sealed compartment region perimeter when opening the container.
The line of weakness may comprise a first end extending across a first part of the sealed perimeter of the compartment region and a second end extending across a second part of the sealed perimeter of the compartment region. Advantageously, first and second ends of the line of weakness extending across first and second parts of the sealed compartment region perimeter may further facilitate opening of the compartment region when a user breaks the container along the line of weakness.
Preferably, a central portion of the line of weakness extends across part of the unsealed area of the access region. Advantageously, when opening the container, a user may first break the container at the central portion of the line of weakness. Advantageously, breaking the container at the central portion of the line of weakness in the unsealed area may allow a user to separately grasp the first substrate layer and the second substrate layer. Advantageously, pulling the first substrate layer away from the second substrate layer at the central portion of the line of weakness may propagate further breaking of the line of weakness simultaneously from the central portion to the first end of the line of weakness and the second end of the line of weakness.
The line of weakness may be linear. In other words, the line of weakness may extend along a substantially straight line. Advantageously, a linear line of weakness may facilitate simple manufacture of the container. Advantageously, a linear line of weakness may facilitate a user tearing or otherwise breaking the container along the line of weakness. A linear line of weakness may be particularly advantageous in embodiments in which the line of weakness extends between a first edge of the container and a second edge of the container.

Advantageously, the second line of weakness at least partially overlying the first line of weakness may facilitate a user breaking the container along both the first line of weakness and the second line of weakness at the same time.
The second line of weakness may have a different shape to the first line of weakness. Advantageously, the second line of weakness having a different shape to the first line of weakness may result in a part of the first substrate layer having a different shape to a part of the second substrate layer when the container is broken along the first line of weakness and the second line of weakness. Advantageously, providing part of the first substrate layer with a different shape to part of the second substrate layer after the container has been broken along the first line of weakness and the second line of weakness may facilitate a user separately grasping the first substrate layer and the second substrate layer at the unsealed area. Advantageously, providing part of the first substrate layer with a different shape to part of the second substrate layer after the container has been broken along the first line of weakness and the second line of weakness may provide the container with one or more additional features or functions.
Preferably, the difference in shape between the first line of weakness and the second line of weakness defines a closure tab in the second substrate layer in the unsealed area of the access region. Advantageously, the closure tab may facilitate reclosing of the container after the container has been broken along the first line of weakness and the second line of weakness. For example, a part of the first substrate layer may be tucked underneath the closure tab formed by the second substrate layer to retain the first substrate layer in a closed position.
Preferably, the first portion of at least one of the first substrate layer and the second substrate layer comprises a recess, wherein the recess at least partially defines the compartment for containing one or more consumer goods.

The line of weakness may comprise at least one of a perforation line, a fold line, a creasing line and a scored line. Preferably, the line of weakness comprises a perforation line. Advantageously, a perforation line may be easy to form during the manufacturing process of the first substrate layer, the second substrate layer, or the container.

The second line of weakness 131 has a different shape to the first line of weakness 128 so that the second line of weakness 131 only partially overlies the first line of weakness 128. In particular, end portions of the second line of weakness 131 overlie corresponding end portions of the perforation line 129 of the first line of weakness 128. However, a central portion of the second line of weakness 131 is shaped to define a tab 143. The function of the tab 143 is described in further detail below.
Although the first substrate layer 8 is not secured to the second substrate layer 10 at the unsealed area 22, the completely sealed access region perimeter 20 makes it difficult to separate the first substrate layer 8 from the second substrate layer 10. Therefore, the completely sealed access region perimeter 20 reduces the risk of the container 4 being opened accidentally.
Opening of the container 4 to remove the aerosol-generating article 6 from the container 4 is a two-step process.
Firstly, a user bends the container 4 to break the first substrate layer 8 along the first line of weakness 128 and to break the second substrate layer 10 along the second line of weakness 131. The outcome of this step is shown in
Secondly, a user separately grasps the first substrate layer 8 and the second substrate layer 10 at the unsealed area 22 and pulls the first substrate layer 8 and the second substrate layer 10 away from each other to detach the first substrate layer 8 from the second substrate layer 10 at the sealed compartment region perimeter 18.
