Definitions

  • the present invention relates to a dust proof container, a dust mask assembly and a method of manufacturing a dust proof container.
  • Dust proof containers are used in many circumstances.
  • a dust proof container is particular useful is for the purpose of storing a dust mask when the dust mask is not in use.
  • a worker may enter a dusty location, such as a workspace, a construction site, or a site in need of cleaning.
  • the worker may wear a dust mask in order to prevent inhaling dust.
  • the dust comprises fine particles of various materials, such as concrete, wood, fiberglass, metal, gypsum, silica or the like.
  • Dust masks need to be dust free on the inside, i.e. the side which is intended to cover the nose and mouth of the user, for several reasons.
  • This dust may be inhaled by the user when the user is wearing the mask.
  • Another reason is that a dusty dust mask may not be able to fit tightly around the user's nose and mouth and in such cases the dust mask will not function properly.
  • prima facie dust proof containers exist, such as water proof containers.
  • An example may be a container having a sealable opening, e.g. a water proof zipper.
  • water proof zippers are generally not intended for dusty locations since dust may damage the sealing properties of the water proof seal to such extent that the seal will be jammed and/or leaking.
  • CN 204015178U discloses a storage bag for a dust mask. This bag is foldable and connected to the dust mask and thus it cannot be ensured that the bag will not become dusty when the user enters the dusty location.
  • Dust may affect the sealing properties of the container such that it does not seal off correctly. Dust may also increase the wear of the opening mechanism of the container.
  • a dust proof container defining an outer layer being made of a reinforcing web material and an inner layer adhered to the outer layer and being made of an elastomeric material, the container defining a sealable opening between a first edge of the container and a second edge of the container, the container further comprises a locking part located on the outer layer at the opening, the locking part defining an open state in which the first edge and the second edge are spaced apart, and a closed state in which the elastomeric material of the inner layer at the first edge is contacting the elastomeric material of the inner layer at the second edge.
  • the elastomeric material may e.g. be rubber.
  • the expression dust proof should be interpreted to mean that the container should not allow small solid particles generated from various industrial or constructional work into the container. It is not necessary for the present container to be entirely liquid or gas tight.
  • the container may be of different sizes; however, preferably, the present container is made for being carried on or by a human.
  • the container defines an inner space which is protected from dust, and the size of the inner space is preferably sufficient for accommodating a dust mask.
  • the web material at the outer layer of the container should be substantially durable to withstand any tear and wear exposed to the container in a typical industrial or constructional environment.
  • the outer layer in particular protects the inner layer of elastomeric material.
  • Elastomeric materials are flexible but may easily break or be damaged when subjected to external forces from e.g. tools or abrasive materials.
  • the opening is defined between opposing first and second edges of the container and allows access to the inner space of the container.
  • the opening should during normal use be closed off and especially then the user enters a dusty area.
  • the inner space will be kept dust free for accommodating or to accommodate a piece of equipment, such as a dust mask.
  • the locking part keeps the opening closed during such normal use of the container. When the inner space of the container should be accessed, the locking part is operated in order to briefly expose said opening, where after the locking part is operated again to seal off the opening.
  • the first and second edges may be protected from dust.
  • the locking mechanism must not be made dust proof and may be made sufficiently rigid and durable to not be damaged by dust.
  • the locking part in the closed state is covering the first edge of the container and the second edge of the container. In this way the edges, which constitute the sealing elements which prevent dust to enter the inner space of the container, is protected from the outside.
  • the locking part is a zipper.
  • the locking part is preferably a zipper which allows the container to be quickly opened thereafter quickly closed and sealed.
  • the zipper should preferably be durable and mechanically resistant to dust, however, it must not be dust proof.
  • the locking part may alternatively be made of e.g. Velcro.
  • the zipper is permeable to dust particles having a size of less than 1um, preferably less than 10um, more preferably less than 100um, most preferably less than 1mm.
  • the above sizes are typical for the present dust particles generated by industrial work and/or construction work. Since the above particles are allowed to go through the zipper, these particles will not jam or damage the zipper.
  • the zipper is stitched onto the container by stitches adjacent the first edge and the second edge.
  • the zipper is preferably stitched onto the container, i.e. the first and second edges, which constitute the sealing element for sealing of the opening and making the container dust proof, are protected from external forces from the outside by the zipper.
  • the zipper should be stitched on such that when the zipper is closed, the opening is sealed.
  • the elastomeric material is a foamed polymeric material such as neoprene or a porous material such as gore-tex.
  • a foamed polymeric material or a porous material will allow the formation of open cells at the first and second edges. When the first and second edges contact to seal off the inner space, the open cells will allow any dust particles which may have accumulated at the edge to enter the open cells and thus not inhibit the sealing performance of the edges.
  • the reinforcing web material is textile.
  • the textile may be .e.g. natural textile such as cotton or synthetic textile such as nylon.
  • the textile should be durable and be able to be adhered to the elastomeric material for supporting the elastomeric material.
  • the container further comprises a belt clip.
  • the belt clip is used for attaching the dust proof container to a belt or other piece of clothes worn by the user.
  • the container has a substantially cylindrical shape.
  • a cylindrical shape i.e. a cylinder bounded by two opposite circular surfaces, allows for a large inner space, suitable for accommodating e.g. a dust mask.
  • the first and second edges of the dust proof container when the locking part is in the closed state, defines a circular arc.
  • the dust proof container is preferably opened along the cylindrical wall of the cylindrically shaped container.
  • the circular arc defines an angle of between 90° and 270°, preferably between 120° and 240°, more preferably 150° and 210°, most preferably 180°.
  • Such arc length allow for a sufficiently large opening to be able to remove and introduce equipment, such as a dust mask.
  • the zipper is made of rigid plastic or metal.
  • the above materials are not necessarily water proof, but sufficiently rigid to not be damaged by most dust particles.
  • the dust proof container defines an innermost layer being adhered to the inner layer opposite the outer layer, the innermost layer being made of a reinforcing web material such as textile.
  • the innermost layer is made of a reinforcing web material such as textile.
  • such layer protects the elastomeric layer in case the container is used for other purposes such as storing nails etc.
  • the above assembly according to the second aspect is preferably used together with the container according to the first aspect.
  • the above method according to the third aspect is preferably used together with the container according to the first aspect and/or the assembly according to the second aspect.
  • FIG. 1 is a perspective view of a dust mask assembly 10.
  • the dust mask assembly 10 comprises a dust mask 12 and a dust proof container 14.
  • the dust mask 12 comprises a flexible pad 16 which has a shape for covering the nose and mouth of a human user and sealing against the face surrounding the nose and mouth of said user.
  • the dust mask 12 further comprises a resilient strap 18 which is connected to the flexible pad 16.
  • the strap 18 is intended to be put about the head of the user for allowing the flexible pad 16 to remain on the face of the user and apply a sealing pressure onto the face surrounding the nose and mouth of said user.
  • the flexible pad 16 further comprises a filter 20 for filtering the air and remove any dust particles contained in the air inhaled by the user from the surroundings.
  • the dust proof container 14 comprises an opening 22 for allowing the dust mask 12 to be introduced into the dust proof container 14.
  • the dust proof container 14 has an outer layer 24 and an inner layer 26, whereby the outer layer 24 faces the outside of the dust proof container 14 and the inner layer 26 faces the inside of the dust proof container 14.
  • the outer layer 24 is made of a textile material in order to provide a wear resistant and substantially rigid outer surface of the dust proof container 14.
  • the inner layer 26 is made of neoprene in order to be completely dust proof.
  • the inner layer 26 is covered by an innermost layer of textile (not shown) which allows the inside of the dust proof container 14 to be wear resistant and substantially rigid.
  • the dust proof container 14 must not be water proof, but preferably capable of withstanding spray water such as rain.
  • the opening 22 may be closed by the user via a zipper 28 bridging the opening 22.
  • a zipper 28 By closing the zipper, mutual edges 30 of the inner layer 26 will contact as will be shown in more detail in the next figure.
  • FIG. 2 is a perspective view of the dust proof container 14 and a close-up of the zipper 28 when the opening 22 is closed.
  • the zipper 28 is stitched onto the dust proof container 14 outside the outer layer 24 and bridging the opening 22.
  • the zipper 28 causes the first edge 30 and the second edge 30', which together defines the opening 22 of the dust proof container 14, to contact each other and seal off the opening.
  • the size and shape of the container 14 and the corresponding interior space of the container 14 should be appropriate for the dust mask to be stored inside the container 14 without crumpling the dust mask.
  • a too small container 14 in relation to the dust mask may cause the dust mask to be jammed between the first edge 30 and the second edge 30' so that no proper dust proof seal is established when the zipper 28 is closed.
  • the zipper 28 is preferably of a wear resistant type which does not have to be dust proof. In this way, small dust particles which enter the zipper 28 will do minimal damage to the zipper 28.
  • the zipper 28 applies a contact force between the first edge 30 and the second edge 30', which allows the first edge 30 and the second edge 30' to establish a dust proof sealing between the corresponding edges of the inner layer.
  • the inner layer is substantially protected from dust and being neoprene will establish a proper sealing even if slightly contaminated with dust.
  • FIG. 3 is a perspective view of the front side and the rear side of dust proof container 14.
  • the rear side comprise a belt clip 34.
