Description
CONNECTED CONTAINERS FOR RAZOR CARTRIDGES
FIELD OF THE INVENTION
The present invention relates to a container for a razor cartridge and more particularly to a plurality of connected containers for razor cartridges.
BACKGROUND OF THE INVENTION
The need for protective containers for razor cartridges has long been recognized. Protective containers protect both the user from accidental injury from exposed cutting edges of the blades within the razor cartridge and protect the razor cartridges and blades themselves from nicks and other damage. In general, there are two types of protective containers: a container for holding an individual razor cartridge and a tray-type container for holding multiple razor cartridges.
The two types of containers have certain advantages and disadvantages. For example, individual containers may be simple and provide a more efficient use of packaging space when quantities of cartridges other than the tray size are used; yet they may be inconvenient both to a manufacturer and a user for storing multiple razor cartridges together. In another example, while a tray-type container is convenient for storing together multiple razor cartridges its flexibility is limited as it can only store a fixed number of razor cartridges.
Another type of container allows individual containers to be connected in a side-by-side relationship. Allowing protective casings to be connected in a side-by-side relationship provides the manufacturer with flexibility to connect together the desired number of protecting casings, e.g., two, three, four, etc. Such connections between containers are often made with an interference snap fit which does not always provide a high degree of integrity to maintain the connection.
Thus, there is a desire to overcome the problem associated with prior art protective casings by providing individual containers that are connected to one another with a connection having a high degree of integrity to maintain the connection.
SUMMARY OF THE INVENTION
The present invention relates to a plurality of connected individual containers for a razor cartridge comprising a first individual container containing a single razor cartridge and a second individual container containing a single razor cartridge. The first individual container comprises a cover removably attached to a sealing surface of the first individual container. The sealing surface comprises a first side and a second side. The first side comprises a first attachment extension extending beyond the sealing surface and the second side comprises a second attachment extension extending beyond the sealing surface. The second individual container comprises a cover removably attached to a sealing surface of the second individual container. The sealing surface comprises a first side and a second side. The first side comprises a first attachment extension extending beyond the sealing surface and the second side comprises a second attachment extension extending beyond the sealing surface. A weld secures the first attachment extension of the first individual container to the second attachment extension of the second individual container.
The weld may be a laser weld or an ultrasonic weld.
The cover preferably comprises a removable film.
The second attachment extension may comprise a notch, designed to direct a separation break between the tubs. The sealing surface comprises an outermost edge. The notch is preferably positioned below the outermost edge of the sealing surface.

The second side 42 comprises a second attachment extension 43 extending outward beyond the sealing surface 26.
Referring to Figs. 4-6 there is shown a second individual container 120 of the present invention. The container 120 is sized to contain a razor cartridge, not shown in Figs. 1-3. The second container 120 is the same as first container 20. The second container 120 preferably comprises a plastic container defining a storage region 124 and having a sealing surface 126 surrounding an entrance 128 to the storage region 124. The container 120 has a first side wall 130, a second side wall 132 opposite the first side wall 130, a first end wall 134, a second end wall 136 opposite the first end wall 134 and a bottom wall 138 extending between the first side wall 130, the second side wall 132, the first end wall 134 and the second end wall 136.
The sealing surface 126 comprises a first side 140 and a second side 142 opposite the first side 140. The first side 140 comprises a first attachment extension 141 extending outward beyond the sealing surface 126. The second side 142 comprises a second attachment extension 143 extending outward beyond the sealing surface 126.
Referring now to Fig. 7 there is shown a container 20, 120 comprising a storage region 24, 124 and having a sealing surface 26, 126 surrounding an entrance 28, 128 to the storage region 24, 124. The container 20, 120 is sized to contain a razor cartridge 50. Razor cartridge 50 comprises a bottom surface 51 and an opposing top surface (not shown). Razor cartridge 50 comprises a plurality of blades 53. Razor cartridge 50 comprises a pair of handle connecting members 54 for connecting the razor cartridge 50 to a handle. The handle connecting members 54 are positioned near an end edge of razor cartridge 50.
Referring now to Fig. 8 there is shown a plastic container 20, 120 defining a storage region 24, 124 and having a sealing surface 26, 126 surrounding an entrance 28, 128 to the storage region
24, 124. The container 20, 120 is sized to contain a razor cartridge 50. The container 20 includes a cover 60 that is sealed to the sealing surface 26, 126 and covers the entrance 28, 128 to the storage region 24, 124. Cover 60 is shown in the form of a removable film 60 that is sealed to the sealing surface 26, 126 by heat welding. Alternatively, radio frequency sealing or other techniques such as an adhesive may be employed. The removable film 60 protects the razor cartridge 50 prior to use. In addition, the removable film 60 can also assist in containing the razor cartridge 50 within the container 20, 120 prior to use.
The removable film 60 may be a single layer film or a laminate of multiple layers of film. Preferably, the removable film 60 is a laminate of PET, polyethylene, polyester-urethane and polyethylene-EVA. The polyethylene layers may be high density polyethylene, oriented high density polyethylene, and low density polyethylene.
Referring now to Fig. 9 there is shown a plurality of interconnected containers, 20 and 120. Containers 20 and 120 are shown with the removable film removed. Containers 20 and 120 are connected together such that the razor cartridges 50 are oriented the same way. This can be seen as the handle connecting members 54 are all positioned on the same side of containers 20 and 120. A weld 70 secures the first attachment extension 41 of the first individual container 20 to the second attachment extension 43 of the second individual container 120. The weld 70 may be a laser weld or an ultrasonic weld. The weld 70 shown in Fig. 9 is a continuous weld extending uninterrupted. Other welds may be used to secure the first container to the second container. Referring to Fig. 10 there is shown another suitable weld 71. Weld 71 includes spaced apart incremental welds 72. Other weld shapes and sizes may also be used.
While two containers 20 and 120 are shown in Fig. 9, any number of containers may be secured together by a weld. If the user wants to separate the containers from one another, the user can simply grasp each container in one hand and bend or pry the containers apart. Preferably, the containers will separate from one another along weld line 70.
Referring now to Fig. 11 there is shown a plurality of interconnected containers, 20 and 120. Containers 20 and 120 are shown with the removable film removed. Containers 20 and 120 contain razor cartridges 50. A weld 71 secures the first attachment extension 41 of the first individual container 20 to the second attachment extension 43 of the second individual container 120. The weld 71 may be a laser weld or an ultrasonic weld. Weld 71 includes spaced apart incremental welds 72.
The second attachment extension 43 contains a notch 75. Notch 75 creates a weakened structure allowing the two containers 20 and 120 to separate from one another at notch 75 when pried apart. Ideally the notch 75 is positioned below the outermost edge 27, 127 of sealing surface 26, 126. Positioning the notch 75 below outermost edge 27, 127 allows for a relatively clean break of material when the containers 20 and 120 are separated from one another. Preferably the notch 75 extends the length of second attachment extension. If the user wants to separate the containers from one another, the user can simply grasp each container in one hand and bend or pry the containers apart. The containers will separate from one another along the notch next to the weld as the notch is designed to direct the break in a straight line. Breaking along a straight line creates a smooth surface eliminating or reducing the potential of creating sharp edges or surfaces. Preferably, the strength of the weld is stronger than the container material such that separation occurs along the notch and not along the weld.
Referring now to Fig. 12 two containers 20 and 120 have been separated from one another along notch 75 shown in Fig. 11. As can be seen weld 71 comprising individual welds 72 still secures second attachment extension 43 to container 20. A smooth surface 75 is created on container 20 after the separation from container 120. A smooth surface 76 is created on container 120 after separation from container 20. Containers 20 and 120 contain razor cartridges 50.
The containers are preferably formed from plastic. The containers may be manufactured from generally translucent or transparent polymers such that consumers can view the shaving
heads. Opaque plastics may even be used if transparency is not required for the containers. Examples of transparent or translucent polymers may include, but are not limited to polyolefins (e.g., polypropylene, high density polyethylene or low density polyethylene), polyesters (e.g., polyethylene terephthalate (PET)), and poly vinyl chloride (PVC). The containers may be produced by thermoforming or other known processing methods such as injection molding, blow molding, cold forming, and injection blow molding.
