Definitions

  • the present invention relates to a structure of automatically tearing a hole out of a slip-in type sanitary cover for toilet seats and, more particularly, to a structure using dot-shaped hot-melt pressing/bonding points formed on a plastic film by hot melting and subsequent pressing bonding, wherein the dot-shaped hot-melt pressing/bonding points can hook a front end of a toilet seat such that when the toilet seat is slipped-into a sanitary cover including the plastic film, the point-shaped hot-melt pressing/bonding points automatically tear a hole out of the plastic film for excretion purposes.
  • FIG. 1 shows a conventional toilet seat device including a toilet seat 11 and a cover 10 pivotably connected to a rear end of the toilet seat 11 .
  • the toilet seat 11 is substantially elliptic and includes an outer rim 111 extending downwardly from an outer side thereof.
  • a substantially elliptic seat hole 12 is defined in a center of the toilet seat 11 .
  • An inner rim 112 extends downwardly from an inner side of the toilet seat 11 .
  • sanitary covers have been researched and invented, the results were not satisfactory. For example, some sanitary covers deformed or slid (and, thus, difficult to position) after users sit on them. Some sanitary covers made of paper are apt to be wetted (and, thus, could not be used) by water or urine. Automatic equipment for manufacturing the sanitary covers is expensive. Obviously, the prior art sanitary covers have many disadvantages, and seldom of them address the issue of easy carriage.
  • This application discloses a slip-in type sanitary cover for toilet seats 21 in the form of a bag including two opposite sides, a bag opening formed at a side of the slip-in type sanitary cover 21 , two side edges respectively located at the opposite sides of the slip-in type sanitary cover 21 , a closed side opposite to the bag opening, a bag space 31 formed in the slip-in type sanitary cover 21 and formed between the bag opening, the side edges, and the closed side, and an excreting hole 22 formed through a central section of the slip-in type sanitary cover 21 and communicating with the bag space 31 .
  • FIG. 2 is a top view of the conventional slip-in type sanitary cover 21 .
  • FIG. 3 is a perspective view of the conventional slip-in type sanitary cover 21 .
  • FIG. 4 is a top view of the conventional slip-in type sanitary cover 21 , with a toilet seat received in the conventional slip-in type sanitary cover 21 ready for use.
  • the first one includes automatically forming the excreting hole 22 by removing plastic films during the manufacturing process.
  • the hollow product (see FIG. 2 ) is apt to deform and, thus, can not be folded by a machine into a small-size product. Namely, human labor is required to proceed with the folding process, which is expensive in costs and is slow in proceeding, failing to meet the production effect.
  • Automatic folding by a machine involves repeated folding of a “complete rectangular object” to form a small-size product.
  • the “complete rectangular object” includes a stable structure and a stable shape to allow automatic folding.
  • the shape of a hollow product becomes irregular when it is folded in half along the middle line, such that the machine can not fold the hollow product in half again. This is why automatic folding can not be conducted on an easy-to-deform structure.
  • the plastic films are manually removed after manufacturing instead of removal by a machine.
  • the plastic bag is cut along a peripheral edge of the excreting hole 22 to be formed, and a plurality of small-area connecting points remains on the peripheral edge.
  • a tear line including a plurality of dotted or dashed perforations can be formed along the peripheral edge of the excreting hole 22 to be formed, and the plastic films can manually be torn off to form the excreting hole 22 .
  • the disadvantages of the conventional slip-in type sanitary cover 21 for toilet seats include: (1) an increase in the labor cost if automatic folding could not be used, (2) troublesome manual removal of the plastic films is required if the plastic films of the product are not automatically removed during manufacturing, or (3) the risk of blockage of the toilet if the manually torn plastic films are thrown into the toilet.
  • the slip-in type sanitary cover is a plastic bag and includes a cut peripheral edge to define a plastic film.
  • the slip-in type sanitary cover is adapted to receive a toilet seat.
  • the plastic film is adapted to be torn along the cut peripheral edge to form a hole allowing passage of feces and/or urine of a user using the toilet seat received in the slip-in type sanitary cover.
  • a plurality of extremely-small-area connecting points is provided on the cut peripheral edge of the plastic film. The extremely-small-area connecting points are spaced from each other. A larger-area connecting point is located on a front end of the cut peripheral edge of the plastic film.
  • the plastic film is connected to the sanitary cover by the plurality of extremely-small-area connecting points and the larger-area connecting point before forming the hole.
  • the plastic film includes at least one hot-melt pressing/bonding point.
  • the at least one hot-melt pressing/bonding point is adapted to hook a front edge of an outer rim of the toilet seat when the toilet seat is slipped into the slip-in type sanitary cover.
  • the plurality of extremely-small-area connecting points is pulled and torn off to form the hole when the toilet seat is completely slipped into the slip-in type sanitary cover.
  • the larger-area connecting point is adapted to be still connected to the plastic bag after the hole is formed.
  • the cut peripheral edge can include a plurality of dash-shaped perforations.
  • the at least one hot-melt pressing/bonding point can be dot-shaped.
  • the cut peripheral edge further includes a rear end spaced from the front end of the cut peripheral edge in a length direction.
  • the cut peripheral edge further includes two lateral sections spaced from each other in a width direction perpendicular to the length direction. Each of the two lateral sections extends between the front and rear ends of the cut peripheral edge.
  • the extremely-small-area connecting points are located on the rear end and the two lateral sections of the cut peripheral edge.
  • the sanitary cover includes a plurality of hot-melt pressing/bonding points located between the two lateral sections of the cut peripheral edge.
  • the plastic film includes left and right sides spaced from each other in the width direction and located between the two lateral sections of the cut peripheral edge.
  • the hot-melt pressing/bonding points can include a first row of hot-melt pressing/bonding points located on the left side of the plastic film and a second row of hot-melt pressing/bonding points on the right side of the plastic film.
  • the first row of hot-melt pressing/bonding points are spaced from each other in the length direction.
  • the second row of hot-melt pressing/bonding points are spaced from each other in the length direction.
  • the first and second rows of hot-melt pressing/bonding points are located between the front and rear ends of the cut peripheral edge.
  • the primary technical feature of the sanitary cover according to the present invention is that the sanitary cover can hook the front edge of the outer rim of the toilet seat by the hot-melt pressing/bonding points, and the plastic film can be automatically torn off to form the hole during the slipping in procedure, with the hole allowing passage of feces and/or urine of the user using the toilet seat received in the slip-in type sanitary cover.
  • the main features of the present invention include:
  • the sanitary cover according to the present invention is a plastic bag and includes extremely-small-area connecting points on the cut peripheral edge thereof for connecting the plastic film to plastic bag.
  • the shape and the structure of the plastic bag can be maintained to allow automatic folding by a machine.
  • the hot-melt pressing/bonding points on the plastic film can hook the front end of the toilet seat while slipping the toilet seat into the sanitary cover, such that the extremely-small-area connecting points can be pulled and torn off to form the hole for excretion purposes.
  • the larger-area connecting point on the cut peripheral edge keeps the connection between the plastic film and the plastic bag after formation of the hole, avoiding the plastic film from being torn off from the plastic bag and preventing the plastic film from falling into and blocking the toilet.
  • the sanitary cover according to the present invention is not formed during manufacture. Instead, only a portion of the peripheral edge of the plastic film for forming the hole is cut, but the plastic film is still connected to the plastic bag by the extremely-small-area connecting points.
  • the shape and the structure of the plastic bag are stable and, thus, allow automatic folding by a machine.

  • FIG. 5 is a schematic top view of a slip-in type sanitary cover 21 for toilet seats according to the present invention.
  • the slip-in sanitary cover 21 includes a central area having a cut peripheral edge H to define a plastic film 22 P that can be torn along the cut peripheral edge H to form a hole allowing passage of feces and/or urine of a user using a toilet seat 11 received in the slip-in type sanitary cover 21 .
  • a plurality of extremely-small-area connecting points G and a larger-area connecting point Gend are provided along the cut peripheral edge H to provide connection for maintaining the shape of a complete rectangular plastic bag.
  • Such a complete rectangular plastic bag has a stable structure and is, thus, less likely to deform during folding.
  • automatic folding can be conducted by a machine to save the manufacturing costs of human labor, unlike the hollow product of FIG. 2 that immediately turns into an irregular shape once folded and is, thus, can not be automatically folded by a machine (detailed description has been set forth in the background of the invention).
  • the extremely-small-area connecting points G are located on the cut peripheral edge H of the plastic film 22 P. Since the area of each extremely-small-area connecting point G is extremely small, a very little force is sufficient to tear off the extremely-small-area connecting points G.
  • the larger-area connecting point Gend is located on a front end of the cut peripheral edge H of the plastic film 22 P. Namely, a longer, uncut section is provided between two end points of the cut peripheral edge H adjacent to a front side 211 c of the sanitary cover 21 .
  • the present invention further includes special designs to avoid the plastic film 22 P from being completely torn off from the plastic bag, preventing the plastic film 22 P from falling into the toilet and blocking the toilet.

Furthermore, the first and second rows of hot-melt pressing/bonding points D1l-Dnl, D1r-Dnr are located between the front and rear ends of the cut peripheral edge H.
  • the conventional sanitary cover 21 of FIGS. 2-4 is manufactured by a conventional method for producing ordinary plastic bags. Specifically, a plastic material is molten and blown to form a plastic tube. The plastic tube is flattened by pressing to form two sides. A hot sealing machine is used to seal an end and, hence, produces a sealing line, and the plastic tube is then cut to obtain a plastic bag having three sealed sides. Finally, an excreting hole is formed by a machine, or dot-shaped or dash-shaped perforations are provided along the excreting hole and can be torn off for use. A slip-in type sanitary cover 21 is, thus, produced.
  • Plastic films possess hot melting and pressing/bonding properties Namely, the plastic films will melt by heat and can be pressed to bond tightly.
  • the sealing line of the above plastic bag is a line formed by sealing an end of the plastic bag by hot melting and pressing/bonding. Thus, for an ordinary plastic bag with three sealed sides, a sealing line obtained from hot melt and pressing/bonding can be seen aside from the two sides resulting from flattening the plastic tube by pressing.
  • the present invention also uses the hot melting and pressing/bonding properties to form a dot-shaped structure including a plurality of hot-melt pressing/bonding points D on the plastic film 22 P. Only one of the hot-melt pressing/bonding points D is sufficient to hook a front edge 111 c of the outer rim 111 of the toilet seat 11 , providing an automatic hole-forming effect.
  • the hot-melt pressing/bonding points D on the plastic film 22 P is a dot-shaped structure formed by the hot melting and pressing/bonding properties of plastic films.
  • Two hot-melt pressing/bonding points D are used to hook the front edge 111 c of the outer rim 111 of the toilet seat 11 .
  • the sanitary cover 21 is further slipped in (i.e., is moved towards the rear end of the toilet seat 11 for receiving more portion of the toilet seat 11 ), and the extremely-small-area connecting points G are pulled and torn off, providing an automatic hole-forming effect.
