Description

Sealed coiled hose with liner

technical field

The utility model relates to a flexible metal crimped hose container, in particular to a sealed crimped hose with an inner liner, which is especially suitable for supplying adhesives such as cyanoacrylates (cyanoacrylates).

Background technique

Commonly used crimped hose containers consist of a main body that holds the contents, with a throat that constricts to a smaller diameter at one end and leads to an open supply first end, and a larger open end at the other end. The second end, the main body is generally tubular but can also be in other forms, the second end is usually used as a filler material into the hose, and then the filling end of the hose is usually closed with a crimp, when the main body is made of plastic When manufactured, the corrugation may incorporate heat sealing or other common plastic bonding processes to close the filling end. As described in my previously published US Patent Application No. 2004/0173558, the contents of which are incorporated herein by reference, such metal hoses are particularly suitable for use with adhesives such as cyanoacrylates. In this case, the mouth is usually closed by a pierceable membrane formed in the throat of the hose, and the cyanoacrylate is filled from the other end, this filling is carried out under controlled atmosphere, In some cases, this can be done under inert gas. Such flexible metal hoses have been filled with cyanoacrylate for many years, and after filling they are crimped and closed in the normal manner, usually involving folding and ramming the filled open end of the hose. When this type of hose is used for items such as cyanoacrylate, by piercing the sealing membrane and squeezing the hose, a small controlled amount of the contents can be delivered, due to the softness and deformability of the hose, it is difficult to maintain accurate The supply pressure is especially important as the hose tends to remain in its squeezed state and not return to its original dimensions. So of course there will be a constant supply when the pinched point is completely recessed or when the material in the hose is lower than where the force is applied. Usually, if the contents are squeezed out, the hose is simply rolled from the crimped end, leaving the upper part of the rolled end in its original uncompressed state or other similar means can be squeezed to provide some controlled Quantity of content. When this hose is in use, it cannot avoid the disadvantage of having to roll the bottom end because it cannot return to its pre-squeeze state, which cannot suck back the part from the neck or mouth or the component tip attached to the mouth materials are unnecessarily restricted. Accordingly, in view of the above-mentioned deficiencies in the implementation of conventional coiled flexible metal hose containers, the use of formed metal hoses for extruded materials such as cyanoacrylates has been developed. As described in U.S. Patent No. 5 799 829 and No. 6 726060, a metal hose that will not be flattened is used for extrusion of cyanoacrylate. When the pressure extruding the outer wall of the metal hose is released, the hose returns to extrusion. The state before pressing can have the effect of sucking back part of the material, but although it overcomes the shortcoming of the crimped soft metal hose, it requires a huge expense. It is possible to obtain some of the same benefits as explained in my previously published application, providing a liner within a coiled hose, for example, which can be formed from a material that is impermeable to the contents of the coiled hose , but has stiffness and resilience sufficient to return the flexible metal hose to its original shape when the external compressive force is released. According to that application, this is achieved when the normal inner diameter of the crimped hose in its filled condition is equal to the outer diameter of the liner. In previous applications, I utilized notches or hollows in the liner to assist the liner in returning to its normal shape after extrusion. Both of these liners allow for more precise squeeze control as they provide a resistance in the squeeze of the hose that is greater than the soft metal of the hose itself and also draw material from the tip of the mouth or the like back into the body Ministry. To some extent, certain disadvantages have been demonstrated that have led to the industry's unacceptability of such liners for flexible metal crimp resistant hoses. The diameter of the liner is the same as the normal maximum inside diameter of the metal hose and may scratch the inside of the metal hose, especially the end of the liner will provide a pressure point which may cause the soft metal crimp hose to fail to complete. Furthermore, during the period in which the liner is compressed, the contents of the hose will find their way into the surrounding area of the liner, and the contents are free to flow through the notches or hollows into the space between the liner and the soft metal coiled hose area, then, when the liner returns to its normal shape, the material will become trapped between the liner and the flexible metal coiled hose or may flow through the gap creating an adverse impact on suction or regurgitation. It would therefore be an improvement in the art of flexible metal crimped hose containers to provide a liner which is resistant to compression without the disadvantages mentioned above.

Contents of the invention

The utility model provides a soft metal crimped hose container body, which comprises a cylindrical main body for storing contents. One end of the container is closed by a throat with a smaller diameter leading to an open supply port. The throat is provided with a piercing Diaphragm, the other end of the main body is closed by a commonly used pleat seal, and there is a deformable and elastic lining in the container, preferably plastic material, and its outer diameter is slightly smaller than the inner diameter of the crimped hose. The inner liner has several passages communicating with the inner side of the inner liner, the outer side and between the inner wall of the coiled hose and the outer wall of the inner liner. The several channels ideally constitute a relatively large proportion of the surface area of the lining, preferably more than 20%, without compromising the elasticity of the lining or the requirement that the lining should use thick walls due to such a large area. In one embodiment of the invention, the soft metal crimped hose has a main body extending from a feed throat opening for thicker material at one end to a reduced diameter at the other end and ending with a rolled or folded and crimped seal. The cross section of the main body is preferably circular. A liner, preferably plastic, is disposed within the main body, having an outer diameter slightly smaller than the inner diameter of the main body and preferably having an axial length slightly shorter than the distance between the throat and the reduced diameter crimped end. In a specific embodiment, the liner itself is cylindrical and is provided with several longitudinal slots at intervals around it. Respective ribs are arranged between the slots, and the ribs are preferably elastic and tough. In a specific example of the present utility model, the inner liner is cylindrical and several axial holes or openings penetrating the inner and outer sides of the inner liner are provided at intervals around the inner liner. The openings can be distributed all around the hose or only in certain parts of the hose. In a specific embodiment of the invention, the liner is formed as a radial and elastic open coil. In all embodiments, the inner liner is resistant to sagging of the extruded flexible metal hose, and when the inner liner itself is dented or deformed, removal of the extrusion re-expands its original shape and pushes the outer tube outward to its original shape, so that A negative pressure is created inside the outer tube to suck back part of the supply into the hose. Since the exterior of the liner is slightly smaller than the normal interior volume of the main body, the liner is free floating within the main body when the main body is in the normal condition of being fully inflated. When the hose is squeezed for use, the compressed portion of the liner may still be in contact with the inner wall portion of the coiled hose because the liner will not return the compressed portion of the hose to their full dimension.

The utility model relates to a flexible metal crimped hose container, in particular to a sealed crimped hose with an inner liner. The purpose of the utility model is to arrange a inner liner inside the main body, on which several openings penetrating the inside and outside are arranged. , the inner liner is formed of a plastic material that will not be penetrated by the contents of the container, it has elasticity and deformability when the container is squeezed, and its resistance to compression is greater than that of the forming material of the main body, because the inner liner is resistant to extrusion The sag of the soft metal hose is resistant, so when the inner liner itself sags or deforms, removing the extrusion will re-expand its original shape and push the outer tube outward to return to its original shape, which makes the inner tube negative pressure and can be sucked back part of the contents into the hose;

Another purpose of this utility model is to take advantage of the soft and deformable nature of the container. The part that is pressed inward and contacts the inner liner generally will not return to its original shape, but maintains the same cylindrical shape as the space. Also, the diameter of the main body portion becomes small. While feeding is done with the container turned upside down with the supply spout facing down, it is the liner that keeps the container cylindrical so that the entire contents of the container can be squeezed out, and since the outside of the liner is slightly smaller than the normal interior space of the hose Small, the liner is free floating inside the main body when the main body is in the normal condition of being fully inflated. Additionally, when the hose is squeezed for use, the compressed portion of the liner may still be in contact with the inner wall portion of the coiled hose because the liner will not restore the compressed portion of the hose to their full dimension.

For realizing the purpose of the utility model, the technical scheme that the utility model adopts is:

A lined, sealed, coiled hose comprising: a flexible metal container having a supply opening at one end, a corrugated closure at the other end, and a main body portion between the two ends; Made of a more rigid material such as soft metal, placed inside the main body of the container, the liner has a hollow interior and an outer diameter formed by an outer wall, said outer diameter being slightly smaller than the main body of the container The inner diameter formed by the inner wall of the inner lining is provided with several openings through the inner and outer sides, and the inner lining has elasticity and deformability when the container is squeezed.

The technical scheme adopted by the utility model also includes:

A lined, sealed, crimped hose, particularly suitable for supplying cyanoacrylate adhesives, comprising an aluminum alloy vessel body consisting of a throat provided at one end and a bellows at the other end. The pleats are sealed and the two ends are formed by a main body space for containing the contents. The main body is formed with a relatively deformable thin wall and has a hollow interior for a liner to accommodate. The liner has a Formed of elastic plastic material, which is more rigid than aluminum alloy container at normal temperature and will not be penetrated by cyanoacrylate, said inner liner has a hollow interior surrounded by a longitudinally extending wall, said The maximum cross-sectional size of the wall is slightly smaller than that of the hollow interior of the main body, and the inner lining is provided with several openings passing through the interior and exterior.

Through the above design, the utility model relies on the negative pressure formed inside the outer tube so that part of the contents can be sucked back into the hose; this is a very satisfactory feature considering a more accurate supply; relying on inversion to supply the contents When the hose is used, the inner liner maintains a cylindrical shape, so that all the contents of the container can be extruded; the main body and the inner liner of the utility model can be realized by common materials, which is economical and practical; in addition, when the hose is fully expanded normally In some cases, the lining is free floating inside the main body, avoiding scratching the inside of the main body. Additionally, when the hose is squeezed for use, the compressed portion of the liner may still be in contact with the inner wall portion of the coiled hose because the liner will not return the compressed portion of the hose to their full dimension.

The purpose, advantages and features of the present utility model will be described in detail below in conjunction with the accompanying drawings.

Detailed ways

Referring to FIGS. 1 to 3 , a container 10 has a relatively deformable thin-walled main body 11 . The upper end of the main body 11 has a neck 12 communicating with a throat 13 , and an opening 14 is provided at the end of the throat 13 . Throat 13 can be formed of a thicker material than main body 11, and can be closed by a diaphragm 16 optionally located on the upper end of opening 14 or a diaphragm integral with container 10, both of which are common in the art well-known to personnel. Container 10 is formed from a soft, crushable metal, such as aluminum alloy, as is well known to those of ordinary skill in the art. The bottom 20 of the body portion 11 generally remains open for filling with the contents of the body portion 11 . After filling, the bottom 20 is closed by a corrugation 21 which can be formed in several known, usual ways of closing, but usually involves flattening the ends of the flexible metal tube so that its two opposite sides are integrated. Subsequently, the flattened portion may form an S-shaped fold as shown at 22 in FIG. 3 or the first fold itself may be further folded to partially overlap. Thereafter the folded portion is usually joined or crimped to close off the bottom of the hose. The exterior 23 of the throat 13 may be threaded for engagement by a cap 24 which may contain a supply nozzle 25 . The cover member 24 may also be provided with a needle member 26 of the type shown in US Pat. No. 6,726,060. The particular type of closure for the container of the present invention can be selected from a wide variety of closures known to those of ordinary skill in the art. Particularly for filling with cyanoacrylate, the container preferably has a lid provided with a supply spout to assist in venting the cyanoacrylate towards the application. A liner 30 is disposed inside the main body portion 11 . The liner is formed of a plastic material that is impermeable to the contents of the container and is more resistant to compression than the forming material of the main body. As shown in Figures 1 to 3 and Figures 8 and 9, the cross-sectional shape of the liner is generally very suitable for the cross-sectional shape of the main body 11 of the container 10, and there is a gap between the inner wall 32 of the main body, The area of the outer wall 33 of the lining is slightly smaller than the inner wall 32 of the main body. Therefore, a gap is formed between the outer wall 33 and the inner wall 32 . In the preferred embodiment, the main body portion 11 is cylindrical and the liner is formed as a cylindrical member such that the outer wall 33 of the liner has an outer diameter and the inner wall 32 of the main body portion has an inner diameter. The axial length of the inner liner 30 is preferably slightly shorter than the axial length of the main body portion 11. When the main body portion 11 is in a fully expanded normal condition, the inner liner 30 can "radially and axially" in the main body portion 11. float". A plurality of longitudinally extending slots 34 are disposed between two ends 35 of the lining 30 , and ribs 36 are formed between the slots 34 . The ribs 36 extend between the two end edges 35, are deformable and elastic and generally provide a spring-like effect, so that when the lining 30 is compressed in a radial direction, it can be restored after the compressive force is released. original shape. When the liner 30 is placed inside the container 10 and the membrane 16 is pierced, compressive pressure is applied to the body of the container, typically between the thumb and forefinger, and the contents of the container may Outflow via supply nozzle 25. Since the main body is made of a soft, formable metal, it is recessed to contact the outer diameter of the liner. During initial depression, material within the body portion can flow through the slot 34 from the space 40 located between the inner wall 32 and the outer wall 33 . Further application of pressure will cause several ribs 36 to twist inwards and the material inside the main body will be fed through the supply nozzle 25 . After the pressure is released, the spring-like action of the ribs 36 will cause the liner to return to its original shape and push up against the main body inner wall 32, expanding the squeezed portion of the main body. This will cause a negative pressure at the delivery end of the spout, causing some of the contents to be sucked back into the spout. Due to the soft, deformable nature of the container 10, the portion that is pressed inwardly into contact with the liner generally does not return to its original shape, but remains cylindrical like the space 40, and the diameter of the main body 10 become very small. A liner 30 diameter of 90% compared to the normal full body portion 11 inner diameter is acceptable, but the space 40 may be larger or smaller. Since feeding must be accomplished with the container turned upside down with the supply spout 25 pointing downwards, it is the liner 30 that holds the container in its cylindrical shape so that the entire contents of the container can be squeezed out. As shown in FIGS. 1-3 and 8 and 9 , the liner 30 with the slotted holes 34 is but one of many different configurations that may be used. For example, in Fig. 4, a cylindrical liner 50 is provided, which is provided with several separate holes or openings 51 spaced apart from each other in its longitudinal direction and circumference, and the openings 51 can be distributed in all or part of the liner while leaving a A continuous axial length 53 (shown in FIG. 5 ) extends between the ends 54 . Other types of liners are shown in Figures 6 and 7, the liner 60 being generally formed as a coil. The liner 60 is preferably radially compressible to have a spring-like action like the ribs 36. Figures 10 to 14 illustrate another type of liner 70 having a plurality of openings spaced around the slot 74. The opposite ends of the cylindrical liner 70 may be provided with V-shaped notches 71 and 72 along the inner The length of liner 70 extends axially leaving a central portion 73 between notches 71 and 72 . The liner 70 around the central portion 73 may be provided with a number of slots 74 to provide a number of ribs 75 similar to the ribs 36 , the liner having a number of openings spaced around the slots 74 . It will therefore be apparent to those skilled in the art that the present invention can be practiced with elastic liners of many different shapes and configurations. The liner has a periphery slightly smaller than the inner periphery of the formed flexible metal container body, thereby providing a floating action of the liner within the container body until the body is pressed into contact with the liner. The liner will resist further deformation of the soft metal body at this press-in, except under the pressure of extrusion. In the preferred embodiment, a cylindrical container and a cylindrical liner are used, provided that the outer diameter of the liner must be slightly smaller than the inner diameter of the inner wall of the main body portion of the container being formed. The difference in diameter can be as large or small as desired, and a personal preference is for it to range between 85-95%. Reducing the diameter of the liner results in more indentation of the hose compared to the main body. The inner liner is preferably provided with several openings through the inner and outer sides, so that the contents can flow freely between the inner and outer walls of the inner liner. The liner is elongated open along its axis which is shorter than the axial length of the formed container defined as the main body between the neck constriction at the feed end and the end of the corrugation. Although I have shown the invention and several selected liner combinations in the preferred embodiment, others may implement the invention in different configurations, using different materials, different sizes and different types of containers, which It will be apparent to those of ordinary skill in the art.

The utility model can be implemented in other different forms without departing from the main spirit and characteristics. Therefore, the above-mentioned preferred embodiments are presented by way of example only, but should not be regarded as limitations of the present invention. Without departing from the spirit and scope of the present invention, many changes and modifications can be made to the present invention, and all of them will fall within the scope of the present invention defined by the claims.
