Abstract

MODELED BREAK BUBBLE WITH INCURSION BREAK FOCUS IN THE DIRECTION INSIDE Merchandise container (10) has specific location break in the burst focus (12F) when the modeled burst bubble (12S) is in compression. The base blade (1OB) and the opposite cover blade (1OC) are pressed together selectively in a double convex receptacle (see Figure 1B). The 12P product chamber and the burst bubble are enclosed within a perimeter seal (14P). The internal seal (141) extends through the container, isolating the product chamber from the rupture bubble. The bubble incursion zone (12Z) moves the perimeter seal inwards towards the rupture bubble. The rupture focus (12F) initiates the rupture at the point or location more towards the incursion zone. The rupture flanks (14K) adjacent to the rupture focus form the rupture edge. The rupture bubble is compressed under external pressure applied by the end user, indicated by the arrows (12C) and (12B) in Figure 1B, causing the opposite blades to separate. The opposite release tabs, cover release tab (14C ) and the base release tab (14B) (see Figure 1C) are provided by the separate opposing blades close to the incursion zone after the rupture of a specific location in the rupture focus.

Description

MODULATED BREAKING BUBBLE WITH INSURING INSURANCE BREAKING FOCUS INSIDE

This claim claims the benefit of provisional application 60 / 790,481, filed April 10, 2006.

TECHNICAL FIELD

This invention relates to a shaped ruptured bubble, and more specifically to such a bubble with an incursion zone which favors a rupture to provide release tabs.

BACKGROUND

United States Patent 6,726,364 issued April 27, 2004 to the present inventor shows a bursting bubble with detaching tabs opposite the breaking edge. The release tabs are pulled by the end user to open a chamber and present a stored product. However, this anterior bubble does not have a break-in favoring raid zone.

SUMMARY

Therefore, it is an object of this invention to provide a merchandise container with a molded rupture bubble which can be easily opened without the use of a sharp instrument or other tool. The end user compresses the bubble causing a break in the edge in a perimeter fence.

Another object of this invention is to provide such a container in which the edge rupture is of specific location. Where the edge break will occur is known not only to the designer but also to the container user. This known rupture orientation is a design and manufacturing benefit and later in use. The rupture occurs at a rupture focus, not randomly along the perimeter fence.

A further object of this invention is to depress such a blister device by having opposite, non-release tabs through which the end user can open the rupture bubble to gain access to a product.

A further object of this invention is to depress such a container formed by single step depressing. Opposite blades are selectively pressed together to make the container. All pressed blade joints may be formed at the same temperature and pressure, and for the same duration.

A further object of this invention is to depress such a bubble device that emits an audible sound from the end rupture. Compression inside the bubble produces an exhaust air precipitation. The nature of the sound of the air escaping is affected by the shape and dimensions of the rupture.

Briefly, these and other objects of the present invention are realized by providing a rupture bubble equipment with a specific location rupture when in a state of compression. At a base blade and an opposite cover blade are selectively pressed together, forming a perimeter seal and a patterned rupture bubble enclosed within the perimeter seal. A zone of bubble incursion along the perimeter sealing shifts the perimeter sealing inwards towards the ruptured leaf. The bursting focus forms part of the perimeter fence at the farthest point within the raid zone. When the rupture bubble is in compression, a focus separation angle F develops between opposing blades in the rupture focus. A similar perimeter separation angle P develops between opposing blades along the perimeter seal. Focus separation angle F is greater than the perimeter separation angle Ρ. The difference in angle promotes greater separation of the opposing blades at the rupture focus than the separation of opposing blades along the perimeter fence. Specific location rupture of the patterned burst bubble occurs at the burst focus.

GENERAL MODE (FIGURE 1 ABC)

Commodity container 10 has specific delocation rupture at burst focus 12F when patterned burst bubble 12S is in a decompression state. The container is formed by the base blade 10Be by the opposite cover blade 10C selectively pressed together in a double convex receptacle (see Figure 1B). The perimeter seal 14P around the container is also formed by selective depressing action. The 12P product chamber and 12S patterned burst bubble are enclosed within the perimeter seal between the selectively pressed opposing blades. The inner seal 141 formed by the selective press extends through the container, isolating the product chamber from the shaped burst bubble. Zone 12Z raid azone along the perimeter seal displaces the perimeter seal in the direction of the rupture bubble.

The rupture focus 12 F forms part of the perimeter fence at the point or location farther inward from the raid zone. Rupture flanks 14K form part of the perimeter fence adjacent to the rupture focus. A rupture flange extends from either side of the burst focus. The raid zone can be any suitable shape such as a V-shaped notch (as

shown in Figure 1A) having an apex in the rupture focus with straight rupture streams extending from the apex.

The rupture bubble is compressed under external pressure applied by the end user (indicated by the arrow 12Ce 12B in Figure 1B) causing the opposing blades to separate. The separation of the blades moves forward, starting at the rupture focus, and resulting in an edge break along the rupture streams into the environment. Opposing release tabs, cover release tabs 14C, and base cover tab 14Β (see Figure 1C) are provided by the separate opposing blades near the incursion zone after specific delocal rupture at the rupture focus. The release tabs can easily be grasped by the end user and pulled apart, causing detachment of the internal seal. With the perimeter seal broken in the raid zone and the inner seal detached, the end user has access to the IOP product within the 12P product chamber. The end user may be the actual consumer who intends to use or operate the product. The end user may involve a facilitator or relative of the actual consumer.

Opposite blades may have multiple layers to provide properties such as waterproofing, UV protection, increased volume and strength. The opposing blades may be of any suitable winding material such as plastic, paper tissue, cellophane, or biodegradable material. Fine mylar plastic is a flexible film with airtight properties, and can be used as a container material. The container perimeter has a rupture seal along the rupture flanges for access to the product, and a non-rupture seal along the remaining perimeter. The snap seal may be a frangible blade joint and the non-break seal may be a destructive blade joint. The frangible rupture seal can be formed at a blade to lower blade pressure and lower temperature for a shorter period than destructive non-rupture seal. The frangible seal is weaker than the destructible seal, and breaks into a lower separation force and requires less compressive pressure applied by the end user.

Further details of a suitable commodity container are disclosed in United States Patent 6,726,364 issued April 27, 2004 to Perell et al., The subject matter of which is incorporated herein by reference in its entirety.

SEPARATION ANGLES (FIGURE IB)

The separation of the blades occurs along the inner edge of the rupture flow seals because the tension on the blades pulls and separates the blades. The stress is due to internal compression within the burst bubble caused by the volume loss resulting from external pressure. Compression forces the blade material to a maximum or "round" volume configuration. Opposite blades separate whenever pressure is not applied, expanding the volume between them. In the dual convex embodiment of Figure 1, IOC cover blade expands upward and IOB base blade expands downward creating a steeper angle between the blades at the burst focus12F.

Angle F is the focus separation angle (see Figure 1B) between the tangents for opposing blades in the bursting point 12F when the patterned bursting bubble 12 is in compression.

Angle P is the perimeter separation angle (see Figure 1C) between the tangents to the blades opposite the perimeter seal 14P when the bursting bubble 12S is in compression.

Angle F is greater than Angle P, because the inwardly incursion zone allows the blunt focus near 12F of the blades to assume a steeper configuration. The steep focal separation Angle F promotes greater separation of the opposing blades in the rupture focus, so separation of the opposing blades along the perimeter seal. The tensioning effect of the blades is most effective at the steeper angle. The larger the easier angle the separation causes specific delocal rupture of the rupture bubble at the rupture focus. That is, the edge rupture occurs along the rupture streams before the rupture can occur anywhere along the rest of the perimeter seal.

COPLANAR MODE (Figure 2)

The OB base blade 2 may be flat and rigid, defining flat blade plane 20F for container 20. Flat containers are convenient for many products such as 20M medicament. The flat base can be manufactured through inexpensive material, easy to work such as cardboard.

Angle F 'is the tangent inward focus separation angle for the 2 OC cover blade and the 2 OF blade plane at the burst focus 22F when the shaped burst bubble 22S is in compression.

Angle P 'is the perimeter separation angle between the tangent for the 2OC cover blade and the blade planar 20F along the 24P perimeter seal when the rupture bubble 22S is in compression.

In coplanar mode, the angle between the flat base blade and the plane of the blades is zero. The angles of the coplanar modality of Figure 2 are approximately half of the corresponding angles of the convex double modality of Figure 1.

The applied external pressure (indicated by arrow 22C) compresses within the bursting bubble 22S, generating a separation force Jf at the separation focus 22Fe a lower separation force Jp along the perimeter sealing 24P.

Force Jf ', the detachment focus separation force, is:

Force Jf '= T (Sine Angle F')

where T is the tangential stress on the opposing blades caused by bursting bubble compression.

The Force Jp ', the separation force along the perimeter is:

Force Jp '= T (Angle P' of sine)

where T is the tangential stress on the opposing blades caused by bursting bubble compression.

As Angle F 'and Angle P' are increased (or decreased) the separation forces increase (or decrease) according to the sine function. The separation forces are maximum at the theoretical maximum separation angle of 90 degrees. The perimeter seal (or a portion thereof) may be coplanar, defining the plane of the blades.

DOUBLE ANGLE (Figure BC)

The general embodiment of Figure 1 has a double convex receptacle with similar tensions and separation forces as the flat base embodiment of Figure 2.

Angle F, the focus separation angle, is the summed Coverage separation angle Cf and the base separation angle Bf.

Angle Cf is the angle between the IOC covering blade at the bursting point 12F and the adjacent collet L of the right triangle which includes the covering separation angle Cf.

Angle Bf is the angle between the base blade IOB at the rupture focus 12F and the adjacent trellet L of the triangle which includes the angle Bf base separation.

Angle Ρ, the perimeter separation angle, is the asoma of the cover separation angle Cp and the base separation angle Bp;

Angle Cp is the angle between the IOC cover blade along the perimeter seal 14P and the adjacent collet of the right-angled triangle which includes the Coverage separation Cp Angle.

Angle Bp is the angle between the base blade IOBao along the perimeter seal 14P and the adjacent collet L of the right-angled triangle which includes the base separation Angle Bp.

The breaking force, Force Sf, at the burst focus is:

Force Sf = T (Angle Cf + Angle Bf Sine)

where T is the tangential stress on the opposing blades caused by bursting bubble compression.

The separation force, Sp force, along the perimeter fence is:

Force Sp = T (Sine Cp Angle + Sine Bp Angle)

where T is a. tangential stress on the opposing blades caused by bursting bubble compression. Force Sf is greater than Force Sp.

The burst focus has a limiting Tsf Force. As applied pressure increases, internal compression and blade tension increase. In addition, the focus separation angle increases as it sheds "fattening", producing an increased sine function. Eventually, the separation force Sf at the breaking focus12F exceeds the limit separation force Tsf, and fails to join the pressed blades. The perimeter seal has a similar limit separation ForceTsp. The limiting force Tsf of the rupture focus is less than the limiting force Tsp of the perimeter fence. The rupture focus for and the perimeter seal not separated under a range of rupture bubble compressions which create a boundary separation force which are: greater than the rupture focus limit separation force Tsf but less than the boundary separation force Tsp perimeter.

Within this crucial range of limits, the separation of the flow seals advances, while the perimeter seal remains intact.

PRODUCT HOLE MODE (Figure 3)

The container 30 has product loading hole 34L where the perimeter seal 34P has not yet been pressed. The hole receives the 3OP product when the 32P product chamber is loaded. During the pressing action in which the 34P perimeter seal and the 34T inner seal are formed, the loading hole is left unsealed. The loading hole is sealed closed during the final pressing action after the loaded melt. The raid zone 32Z may be concave inwardly felt at the rupture focus with curved rupture beams extending from the rupture focus. The raid zone and container may be symmetrical around the rupture focus with symmetrical rupture flows extending from the rupture focus. The general modality of Figure IA is symmetrical around the reference line IB, and the orifice mode of Figure 3 is symmetric around the reference line R. Alternatively, the container may not be symmetrical (as shown in Figure 4). The rupture focus may be a point forming the origin of the rupture foci extending thereafter, as shown in Figure 1A. Alternatively, the rupture focus may occupy a long width of the perimeter seal between the rupture foci extending therefrom, as shown in Figure 4. The burst focus setting and the existence of the burst foci affect the nature of the sound generated by the burst bubble. Rupture sound can be high or moderate, high frequency or low frequency, or long or short as required by the application.

PRODUCT BUBBLE MODE (Figure 4)

In the general embodiment, the product was in a product chamber (see Figure 1). In blistering mode Figure 4, the product is in the bursting bubble. The product chamber and inner seal have been eliminated. The patterned burst bubble 42S has 44P perimeter seal formed by selective pressing action. The raking zone 4 2Z and the bursting focus 42F and the bursting foci 44K are located at one corner of the container 40. The rupture seal at the rupture focus and along the rupture foci may be narrower than the perimeter seal. wide. The narrower rupture seal requires less bubble widening to force an edge rupture, and stops before the perimeter seal can break. In addition, the rupture seal separates at a faster rate than the perimeter seal due to the steeper focus separation angle presented by the patterned burst bubble. To further enhance rupture, rupture flows at the bursting focus may be weaker than the rest of the perimeter seal due to manufacturing limitations of duration and temperature and pressure.

INDUSTRIAL APPLICABILITY

It will be apparent to those skilled in the art that the objects of this invention have been achieved as described above by providing a commodity container with a patterned rupture bubble which can be easily opened without the use of a tool. specific delocalization, and occurs at a rupture focus, not randomly along the perimeter fence. The broken bolt has opposite detachment sides that assist the final user in opening the patterned bubble. The container is formed by a single pressing step, wherein the opposing blades are selectively pressed together. All pressed blade joints are formed at the same temperature, pressure and duration. The threshing device produces an exhaust air precipitation from the edge break that emits an audible sound.
