Description

A wiper for efficient production

Technical field

The present invention relates to medical and domestic wiping appliances, and more particularly to a wiper that facilitates efficient production.

Background technique

Up to now, among the various embodiments involved in the "wiping device and its preparation method" (Patent No.: 200480010343.0, hereinafter referred to as "prior art (1)"), only one of them has been applied in the market, domestic trade, foreign trade. The annual sales volume is less than 100 million. Objectively, the basic performance and use effect of the product is excellent, and the industry and consumers are also well received, but due to the high sales price caused by excessive production cost, in the competition with similar products, the sales price is at The disadvantage is the biggest obstacle to the widespread application of the products involved in the prior art (1).

The direct cause of the high cost of the above products is mainly the product structure designed by the technical solution, so that the corresponding production methods and production equipment cannot achieve higher production efficiency. For the product structure under the prior art scheme, the production process and equipment such as the patent application "Equipment for producing a wiper" (Application No.: 201410417520.2, hereinafter referred to as "Prior Art (2)"), production efficiency It is much smaller than 300/min, and the production cost under this production efficiency is regarded as the basic condition that the product can be widely used.

The above production methods and production equipment have two main constraints, which make their production efficiency low, and the final product cost is too high, which is not conducive to its wider promotion and application.

On the one hand, the product structure under the prior art (1) scheme needs to adopt an integrated production method, that is, in the same production site, a production line (such as extrusion production of tubular containers and rods, tangling at one end of the rod body, and reusing existing technology) (2) such a process completes filling, fusion sealing, etc., to produce the final product; because the product under the prior art (1) cannot be like other products because it contains cotton body (cannot leave a port unsealed) The packaging materials (ampoules, small plastic bottles, etc.) are directly supplied to downstream manufacturers. It is impossible to use the prior art (1) to improve and improve the safety and convenience of the original product by using a large amount of external preparations with a small amount of single use.

On the other hand, the product structure under the prior art (1) scheme will make the process part of the production process take too long, that is, the end of the tubular container is melted together with the cotton-free end of the cotton swab in the tube and closed. process. As in paragraph [0047] of the specification of prior art (2) As described, at this time, the inner cavity of the tubular container 6 has a rod body (cotton swab) with a cotton body at one end, because in the process of the two ends of the closed tubular container, the two ends are melted to the cooling setting. The required pressure is applied from both ends of the tubular container 6 so that the cotton swab in the inner cavity is not subjected to such force.

This allows the rod to remain upright and substantially centered in the tubular container as shown in the prior art (1) drawing, however, such a process also causes the end of the swab body to be fused with the end of the tubular container 6 to form a closed tube. The process of the end takes too long.

Because the rod body does not exert an external force, the limited end face of the rod end is in contact with the inner surface of the hollow mold cavity 3 that can be heated, and the heat is absorbed slowly; and the tubular container 6 is heated due to the applied pressure. The wall of the tube is continuously curled and deformed along the inner surface of the hollow mold cavity 3 under the action of pressure, so that the heat receiving surface of the hollow mold cavity is continuously increased, so that the heat absorption speed is fast, and this "big pipe" appears. The problem of fast heat absorption and slow heat absorption of small tubes. However, the process time required for this step ultimately depends on the time required for the end of the swab body to melt sufficiently, that is, the platen 7 cannot be pressed down quickly and must be sufficiently melted at the end of the rod. Otherwise, when the end of the rod body is not sufficiently melted, if the tubular container 6 is pressed too fast, the molten surface thereof may be closed too fast, thereby causing the sealed end portion to be insufficiently melted by the rod end contained therein, which may result in The leaking gap may cause the rod body to be lifted from the heated end of the rod body, so that the rod body is easy to shake or fall off due to insufficient fusion connection.

In addition, the embodiment of "first sterilization, post-filling" as listed in the prior art (1) is also too complicated due to the design scheme, and the manufacturing cost is too high to be practically used.

In addition, as the wiper provided in the prior art (1) is used in the process of being broken, the working liquid remaining in the inner cavity of the hand-held broken end may drip from the port, causing waste and pollution.

Purpose of the invention

A first object of the present invention is to provide a wiper which is easy to produce efficiently and which is structured to improve production efficiency.

A second object of the present invention is to provide a wiper that facilitates efficient production and can be supplied to downstream manufacturers in the form of a package material, enabling it to be used quickly and widely.

A third object of the present invention is to provide a wiper that facilitates efficient production, which can meet the production process requirements of "pre-sterilized, post-filled working liquid" at the lowest cost.

Advantageous effects of the invention

The invention designs the root of one end of the rod body fused and fixed to the top of the tubular container to be bent, or at the same time, the rod body is arranged in a curved bow shape, such a "curved rod" wiper and the prior art "straight rod" wiper In contrast, not only maintains its good product performance, but also improves its production process, thereby greatly improving production efficiency. In addition, the present invention also provides that the wiper is first made into a cavity container, and then the filling needle is used. The pipe wall or the top end wall thereof fills the inner cavity of the wiper with a new process of working liquid, which not only satisfies the production process requirements of "first sterilizing, post-filling working liquid", but also can be free of working liquid. The cavity wiper is used as a packaging material and is provided to downstream manufacturers (using the method provided by the present invention to inject various working liquids into the inner cavity of the wiper as needed), so that many enterprises can quickly and widely apply such new ones. The packaging material brings good economic and social benefits; in addition, the invention effectively solves the problem that the wiper provided by the prior art (1) is disabled in the process of being broken and used. Leakage of the working fluid left in the lumen of the hand-held end.

The above beneficial effects will be further described below in conjunction with specific embodiments.

One embodiment: Referring to FIG. 1 , a wiper for efficient production is provided by the present invention, which is different from the wiper provided in the prior art (1) at the first end of the rod body (20). (21) an inner surface of the sealed end formed by fusion and fixation with the first end portion (11) of the tubular container (10), and the root portion (23) of the first end portion (21) of the rod body (20) connected thereto is bent The inner wall of the tubular container (10); in addition, referring to Fig. 2, in the cross section of the annular fracture (14) formed after the tubular container (10) is broken along the breakable break (13), the tubular container (10) the length of the shortest line segment between the inner wall and the outer wall of the rod body (20) (the length of the line segment from point a to point b shown in Fig. 2) is smaller than the rod body (20) on the extension line of the shortest line segment. The length of the line segment between the outer wall of one side and the inner wall of the other side of the tubular container (10) (the length of the line segment from point c to point d shown in Fig. 2) is one-half. Further, the material of the wiping body (30) is preferably plant fiber such as cotton wool, synthetic fiber, sponge, and other soft polymer adsorbent materials may be selected; the wiping body may be divided into two parts as needed.

Embodiment 2: Referring to FIG. 3, the outer wall of the rod body (20) touches the inner edge of the annular fracture (14) formed by the tubular container (10) being broken along the easy breakage mark (13), which is shown in FIG. In the case where the length of the line from point a to point b is zero, such a wiper can not only be used normally, but also facilitates the process of using the wiper product to break the tubular container (10) after being broken along the easy breakage mark (13). The working fluid on the inner wall of the first end portion (11) runs along the rod body (20) Flowing down to the wiping body (40) to prevent dripping; in fact, when the inner diameter of the tubular container (10) is less than 20 mm, as long as the length of the line segment ab shown in Fig. 2 is less than one-half of the length of the line segment cd, such The effect of preventing dripping is most obvious; because, due to the action of the liquid tension, the residual working liquid is concentratedly distributed between the rod body (20) and the narrow gap formed by the inner wall of the tubular container (10), when the wiping body is provided (40) When the second end portion (21) of the rod body (20) faces downward, the residual working liquid flows along the outer wall of the rod body (20) to the wiping body (40) without being randomly dripped from the fracture to other places, resulting in waste. And pollution.

Embodiment 3: Referring to FIG. 4, the rod body (20) has a curved bow shape and its arched back touches the inner wall surface of the tubular container (10). This is a cavity wiper provided by the present invention, wherein the rod body ( 20) The base portion (23) of the first end portion (21) is largely bent so that the rod body (20) is deformed into a bow shape and attached to the inner wall surface of the tubular container (10).

Embodiment 4: Referring to Figure 5, the rod (20) uses a circular tube produced by an extrusion process, and is fused at its first end (21) to the first end (11) of the tubular container (10). During the process of closing and joining, the end portion is heated and bent by the axial force; the specific process is that the first end portion (11) of the tubular container (10) and the first end portion (21) of the rod body (20) The end of the die hole (51) is placed in the cavity of the same mold (50); the front end of the pressure body (60) which is given the pressure of the second end portion (12) of the tubular container (10) is specially set. The cylinder (61) can be inserted into the inner cavity of the tubular container (10) so that an axial force can be applied to the rod (20) through the second end (22). Thus, the rod body (20) which is initially straight tubular has its first end portion (21) bent under one direction of heat and force, and the rod body (20) is bent in one direction (the inner wall of the outer tube), especially the root portion thereof. (23) The degree of bending is the greatest; at the same time, the heated end face is rapidly melted and finally merges with the molten portion of the first end portion (11) of the tubular container (10), and after cooling setting, the first end of the tubular container (10) (11) Closed and fixedly connected (fixed) to the first end portion (21) of the rod body (20); at the same time, the rod body (20) which is deformed by bending due to heat and force, especially the root portion (23) Being stereotyped. In this way, the time required for the process in which the first end (11) of the tubular container (10) is fused closed and connected to the first end (21) of the rod (20) is greatly shortened.

Since the first end portion (21) of the rod body (20) is not only heated but also continuously subjected to the axial force, the melting speed of the heated end surface can correspond to the melting speed of the heated end surface of the tubular container, so that the two can improve the heat efficiency of the device. Synchronously reduce the required heating time under the condition; in the prior art, since only the tubular container is subjected to the axial applied pressure, and the rod body is not subjected to the applied pressure, the two are not simultaneously increased in heat, which results in This article is in the background The problem described in the [008] section of the technology, that is, the problem of "fast heat absorption of large tubes and slow heat absorption of small tubes" existing in the prior art and many problems associated with them. It can be seen that the "curved rod" wiper provided by the present invention can greatly shorten the time required for the related production process as compared with the wiper of the original "straight rod" structure, thereby greatly improving the production efficiency.

Please refer to FIG. 6, which is another way of applying axial pressure to the rod body (20), which is mainly used for the process of first sealing the second end portion (12) of the tubular container (10) to be closed. The same technical effect.

Embodiment 5: Referring to FIG. 7, the working liquid in the inner cavity of the tubular container (10) is poured into the inner cavity from the port before the end portion is fused and closed, and a part of the working liquid enters the inner cavity and is immersed. The wiping body of the second end of the rod body, the wiping body impregnated with the working liquid is indicated by the wiping body (40) in the drawing.

Embodiment 6: Referring to FIG. 8, a working liquid is placed in the inner cavity of the tubular container (10), and a tubular pin (15) has a filling pinhole (15) which is fused and sealed. The filling pinhole is left after the working fluid is injected into the inner cavity of the tubular container (10), and the manner of sealing the filling pinhole can be heated to fuse the pinhole. This is an embodiment in which the ends of the tubular container have been closed to form a closed container, and then the working fluid is injected through the wall of the container through the filling needle to seal the pinhole.

Embodiment 7: The partial tube wall corresponding to the fused plug hole (15) is heated and softened before the filling needle is pierced, so that the pretreatment can make the filling needle easy Pierce the wall.

Embodiment 8: The filling pinhole (15) which is fused and sealed is sealed by laser heat fusion, and the sealing method can make the fusion surface very beautiful.

Nineth embodiment: Referring to Fig. 9, a working fluid is placed in the inner cavity of the tubular container (10), and an end wall of the top end of the second end (12) of the tubular container (10) is filled with a fusion seal. Pinholes (15) allow for a better appearance.

The cavity wiper provided by the invention can meet the process requirements of “first sterilization, post-filling” as a new packaging material, and the specific steps are as follows: the sterilized cavity wiper is placed in the clean room. Or under the laminar flow hood, each positioned on the transmission line; at a location on the tube wall between the first end (11) of the tubular container (10) and the frangible trace (13), with its curved surface and tubular The heat conductive rubber of the container (10) which is in agreement with the tube wall contacts the place, heats and softens it; then the filling needle penetrates the softened area and the working liquid is poured into the inner cavity of the tubular container (10); In this way, the outer tube wall around the filling hole is melted to close the filling pinhole.

In this process, the area of the tube wall is softened and softened in advance, which not only makes the filling needle easy to puncture, prevents cracks on the tube wall, but also prevents the puncture site from being broken and chipping to ensure the quality of the product. The heating softening temperature is selected correspondingly by different materials, and an olefin-based material such as polyethylene or polypropylene is preferably in a range of 40 ° C to 100 ° C.

In addition, the choice of laser energy should not be too large, so that the wall around the filling pinhole can be melted and the pinhole can be sealed; the spot of laser heating is slightly larger than the round spot of the filling pinhole, so that " The method of only one puncture and only one pinhole is not only simple and easy to operate, but also allows the appearance of the pipe wall to be better under the premise of ensuring the sealing effect of the filling pinhole. Of course, there are many ways to heat the melt closed pinhole, and laser heating melt sealing is the preferred solution.

With a filling needle with two relatively independent channels, it can be quickly vented; when the filling volume is less than 1 ml, a single-channel filling needle can also be selected to fill the working fluid. In addition, since the softened tube wall is easily pierced, the tip of the filling needle does not need to be too sharp, so that it can be prevented from adversely affecting even if the filling needle penetrates the tube wall even if it touches the rod body.

The technical scheme of injecting working fluid into the cavity closed container of the present invention can be paralleled in different processes and different working positions, so that the filling process can be completed efficiently; and since the process can be re-cleaned The next step is to make the final product meet the pharmaceutical grade standard.

It can be seen that the "post-filling" process technology of the invention can not only ensure the quality of the final product, but also can complete the production process of the "post-filling" process simply and efficiently, and the "post-filling" device is relatively simple. Small size (small footprint).

With such changes, the "wiper" product technology can be quickly and widely used. Because the production of wiper products, you can choose to produce the final product on the same production line (ie, synchronously filling the working liquid), or you can choose to make the product without the working liquid (closed container) as the packaging material. Choose where and when to fill the working fluid as needed. In this way, many companies that are small in scale but need to use "wiper" technology to improve product safety and convenience only need to add "post-filling" equipment and directly purchase "wiper" without working liquid. Packing materials can be used without having to purchase equipment such as extrusion lines, cotton swabs and intubation production lines. Such an industrial division of labor can not only promote the application of "wiper" products without working liquids, such as pharmaceutical packaging materials, but also maximize the performance of production equipment for producing "wiper" without working liquid.

It should be noted that the "post-filling" process technology of the present invention is substantially different from the post-filling technical solution disclosed in the prior art (1), and all of them require complicated structures and specializations. The filling channel of the door setting cannot be practically applied.

In summary, the present invention provides a wiper that facilitates efficient production, and improves the production processability and product performance of the product by changing the structure and shape of the product. The "curved rod" wiper provided by the present invention is Compared with the prior art "straight rod" wiper, not only maintains its good product performance, its structure is easy to greatly improve production efficiency; it can also be supplied to downstream manufacturers in the form of packaging materials, enabling it to be fast, Wide range of applications; can also meet the production process requirements of "first sterilized, post-filling working liquid" at the lowest cost; and can prevent the wiper from remaining in the lumen of the hand-held broken end during the process of being broken and used. The working fluid drip from the port, reducing waste and pollution.

The technical solutions enumerated in the present invention achieve the object of the present invention. It should be noted that the preferred embodiments of the present invention are not limited to the above-listed embodiments, and various modified embodiments are within the scope of the invention as set forth in the claims; In the preferred embodiment, the various links in the embodiments of the various embodiments may also be combined with each other, but their purpose and substantial effects are the same or similar. Equivalent and equivalent alternatives such as these are also within the scope of the invention.
