Blister pack system

Abstract

The technology described herein generally relates to a blister pack system. The blister pack system includes multiple cavities for storing products. For example, four cavities may hold four different products. A technician may extract the four different products in a particular order. The blister pack makes it easy for the technician to determine which product to use first, and to determine which successive product to use even if the orientation of the blister pack is changed during the process.

DETAILED DESCRIPTION

(5) Throughout the specification, wherever practicable, like structures will be identified by like reference numbers. In some figures, components may not be shown for clarity in the drawings. Unless expressly stated otherwise, the term or means either or both such that A or B includes A alone, B alone, and both A and B together.

(6) FIG. 1 generally depicts an embodiment of the blister pack system 100. The blister pack system is generally separable into two parts, the casing 200 (FIG. 2) and the film 300 (FIG. 3). The film overlays and is affixed to the casing, for example by gluing or heat-sealing the film to the casing. In the preferred embodiment, the casing includes four cavities, 110, 120, 130, and 140, and two channels 150 and 160, though alternate embodiments could include more or less of the foregoing.

(7) The film 300 is preferably a fluid impermeable layer. For example, the film may be a metal foil or plastic. Alternately the film could be a combination of metal foil, plastic, or paper.

(8) FIG. 3 is a depiction of an embodiment of the film 300. In the embodiment shown, the film 300 is adapted to cover casing 200 which has four cavities. The film may be a single, uniform piece of film that may be conceptually divided into four sections 310, 320, 330, and 340 where film section 310 covers cavity 110, film section 320 covers cavity 120, film section 330 covers cavity 130, and film section 340 covers cavity 140. The film includes tab 311 extending from the main body of the film and preferably located at a proximal end of the film.

(9) The film sections may alternately be semi-separated, such as by perforations, or completely separated and independent from one another. In the embodiments depicted in FIG. 3, perforation 350 separates section 310 from section 320, perforation 360 separates section 320 from section 330, and perforation 370 separates section 330 from section 340. Preferably, the perforations are formed only in locations that correspond to the flat portions of the casing. That is, the perforations are not formed on a section of the film that, when the film is applied to the casing, would be located above any of the cavities 110, 120, 130, or 140, or above either channel 150 or 160. That prevents the cavities and channels from being contaminated by material transitioning from the outside world through the perforations and into the cavities or channels.

(10) Preferably, each section includes a tab. In the embodiment shown in FIG. 3, section 310 includes tab 311, section 320 includes tab 321, section 330 includes tab 331, and section 340 includes tab 341. As shown, the tab extends from the main body of each section. The tab provides a gripping portion to the film when the film is sealed to the casing. That is, when the film is sealed to the casing, the tab remains unsealed to the casing such that a technician may grasp the tab and pull the tab to peel the film section away from the casing and reveal a cavity. Preferably the tabs are aligned on one side of the main body of the film as shown in FIG. 3, however it is contemplated that they could be oriented on either side or both sides.

(11) In the embodiment shown in FIG. 1, the tabs 321, 331, 341 all extend beyond the outer edge of the casing. That makes it easier for the technician to grasp the tab. However, in one embodiment, the casing also includes a flange 111 (see FIGS. 1 and 2) and the tab 311 does not extend beyond the flange. That structure helps protect the tab from damage. It should be understood that similar flanges could be used to protect other tabs, or no flanges at all could be used.

(12) Utilizing flange 111, however, provides structural support at the proximal end of the casing and creates a nook 170 between the flange 111 and the angled side wall 270. The nook 170 enables a technician to manipulate the orientation of the casing with, for example, a long, thin tool and prevents the tool from simply sliding along the edge of the casing.

(13) While the casing could be any shape, in one embodiment, as shown in FIG. 2, the casing may be substantially rectangular. The proximal end, 210, is tapered whereas the distal end 280 is substantially squared off. In the embodiment of FIG. 2, the casing includes proximal side 220, that is connected to and transitions to tapered side 230, that is connected to and transitions to length 240, that is connected to and transitions to distal side 250, that is connected to and transitions to length 260, that is connected to and transitions to tapered side 270 which includes flange 111, that is connected to and transitions to proximal side 220.

(14) The tapered sides 230 and 270 provide visual cues to the technician as to which end is the proximal end and which end is the distal end when the casing is oriented such that the film is facing up and the cavities are setting on a surface. That in turn informs the technician which product is located in which cavity when different products are held in different cavities.

(15) In one embodiment, cavities 110, 120, 130, and 140 each contain different products. For example, cavity 110 contains a tablet for creating a soaking solution, cavity 120 may contain a scrub compound, cavity 130 may contain a mask compound, and cavity 140 may contain a lotion. In one embodiment, each compound may provide a different scent, such as mint scent for the tablet, vanilla scent for the scrub, cucumber scent for the mask, and mango scent for the lotion. Each product may be contained in successive cavities such that the technician uses each in order, working from the proximal end to the distal end. Thus, the present blister pack can eliminate the need to read any information about the products, and even after the pack is opened, or if the pack gets disoriented during use, the technician may easily reorient the pack (such as by having the proximal end on the left and the distal end on the right) and progress through each product knowing that each product is being used in the correct order.

(16) With respect to the cavities, the cavities may be of any shape. However, it is found that utilizing cavities of the shape shown has distinct advantages. For example, cavity 110 may be circular. Generally, cavity 110 is used to hold a small tablet that is used to create a solution. The circular shape of cavity 110 minimizes the amount of plastic needed to create the casing to house the tablet. It also allows for the formation of tapered sides 230 and 270. The other three cavities, 120, 130, and 140, generally contain fluid substances (such as scrubs, pastes, or lotions). The cavities are provided with flat bottoms 121, 131, 141 to maintain stability of the blister pack when it is set on a counter. Each cavity also has at least one curved side, 122, 132, 142, though it is contemplated that the cavities may be symmetrical. The curved sides 122, 132, 142, allow for ease of extraction of the contents of the cavities. For example, a technician can use a finger to scrape the fluid out of the cavity more easily when the cavity has a curved side than from cavities with substantially squared off sides. In one embodiment the cavities are approximately two inches across and may accommodate one or two human fingers.

(17) As discussed above, the casing 200 may include at least one channel. As shown in FIGS. 1 and 2, channel 150 extends along the length 240. In the embodiment shown, channel 150 is a substantially U shaped recess, though other shapes of channels could be used. The film 300 covers the channel until the film is removed by the technician. Thus, the channel provides a clean location for the technician to store tools. Additionally, because technicians may extract fluid from the cavities with their fingers, the channel alternately provides a location for the technician to scrape excess fluid off of the fingers or tools. In the embodiment shown, there are two channels, 150 and 160. Thus, a technician may use one channel for storing a clean utensil, and use the other to store excess fluid.

(18) It should be understood that the exemplary system described herein and shown in the drawings represents one particular embodiment of the blister pack system. Various modifications and additions may be made to such embodiments without departing from the spirit and scope of the invention. Accordingly, it is intended that the appended claims be interpreted as covering all alterations and modifications as fall within the spirit and scope of the invention.
