Carton Size Modifier

This invention relates to the field of carton size modifier particularly suited for changing the size of any carton by means of simple process.

As everybody knows, the ordinary carton has its fixed size. What it is used for the carriage of the goods, it really causes some troubles to the user about its limitation. The common thing is that the size of the carton is larger than that of goods which we want to move. In order to solve that problem, some people, when they could not find a suitable one, always put the waste paper, sponge debris.. etc. inside the carton for protection of the goods from any collision under shipment. But if the difference in sizes between the carton and the goods is too larger or under the condition that there is no need to have the buffer of the other materials to protect the goods, the stuffing of waste paper or sponge debris . . . between the carton board and the articles would not make sense but only incerease the weight in transportation and the waste of money in payment of the freight. The other method employed by the people is to modify the size of the carton. But till now, in order to change the size of the carton, people usually cut off the excessive paper boards with scissors. Then they would unnaturally fold the outer boards of the carton with their external force in order to make a carton box of new size. But when they fold the paper boards, there is not any folding line to follow. So people always can not make the perfect folding of corner lines into a nice looking carton. Therefore, the modification work for the size of carton causes much trouble.

In view of the above mentioned trouble faced by the users as they found that the size of the carton did not meet their actual need, it is an object of this invention to provide a carton size modifier, by which the people can easily modify the size of the carton approaching to the size of the goods which people want to transport. Besides, the boards of the carton can be easily folded and formed the cartons with various sizes & shapes without any difficulty, thus, save the time for the modification of the carton size.

It is a further object to provide a carton size modifier, by using it, people will not need to stuff the waste paper or sponge debris . . . etc. into the carton, and it can make the size of carton fitted to the size of goods to be loaded in the carton. The user then will save the cost and freight caused by the oversize of carton.

Another object of the present invention is to provide a carton size modifier which can make the size of the carton in agreement-with the volume of articles to be loaded in the carton. Inside carton, only a small quantity of gaskets are necessary to add inside the carton to maintain the stability of the goods in transit, so that they will not overturn in mess during the shipment. To a company, such practice can avoid the complaints usually lodged by clients and the goodwill of it can thus be maintained.

A more complete understanding of these and other features and advantages of the present invention will become apparent from a careful consideration of the following detailed description of certain embodiments illustrated in the accompanying drawings.

FIG. 1 is a perspective view showing a fully assembled embodiment of the invention.

FIG. 2 is a side elevation cross-sectional veiw of the assembled embodiment of the invention.

FIG. 3 is a exploded perspective view showing the components of the invention.

FIG. 4 shows the common method of use on the usage of the present invention .

Referring to FIGS. 1, 2 and 3, there is shown a carton size modifier comprising a tube 1, a supporting clamp 2 on the tube 1 and the hole line forming structure 3 on the bottom end of the tube, wherein, the tube 1 is a long, hollow tubular body. The supporting clamp 2 has a thimble 20 which can encase the tube 1. Two sides of the opening of the thimble 20 extend a board 21, 22 respectively. On the board 21 & 22, there are holes 210, 220 respectively. A bolt 23 screwed into perforated holes 210, 220 from the outside of the board 21/22, and protrudes out of the outer side of the other board 22/21. Then turning the press button 24 to encase the protruding end of the bolt 23, will cause a tight pressure against the baord 22 or 21, and the press button 24 will pull the bolt to make the two boards 21, 22 come closer to each other. The thimble 20 clamps the tube 1 very tightly. If the press button 24 is turned in the reverse direction, it can release the boards 21, 22 and the thimble 20 will not clamp the tube body 1 tightly and the entire supporting clamp 2 can be moved freely. At the bottom of the thimble 20 of the supporting clamp 2 there is a hooking plate 25 extends a short distance in horizontal direction firstly and then extends a small distance downward, whereby to hook up the upper edge of the carton.

As shown in FIGS. 1, 2, and 3, the hole line forming structure at the bottom end of the tube 1 comprising a rotating gear disk unit 31, a pipe seat 32 with a handle and a pressing post 33, wherein, the rotating gear disk unit 31 has a rotating gear disk 311 with an axial hole 311a at its center to let the rotating gear disk 311 encase over an axis tube 314. The semi-circle perimeter of the gear disk is installed with a protection cover 312 made up of a fan board 312b and curve board 312a. At the top face of the fan board 312b, there is a short non-rounded column 312c. The short column 312c' and the fan board 312a have the communicable perforated hole 312d. The perforated hole 312d and the axial hole 311a at the middle of the rotating gear disk 311 are opposite each other to let a stud bolt 313 can be inserted in. The pipe seat 32 is made up of a straight pipe 321 and a handle 322 extends horizontally from the side wall of the straight pipe 321. The bottom part of the straight pipe 321 forms a hole 321 similar to the shape of short column 312c at top face of the protection cover 312 of the above rotating gear disk unit 31. The top face 321a of the straight pipe 321 is cut at an angle. The pressing post 33 is then a post having a complimentary angle at its lower end to match with the top face 321a of the straight pipe 321. At the middle of the top face of the pressing post 33, there is also a concave 33a to contain a nut.

In combination of the hole line forming structure 3, the pressing post 33 is put onto the top face of the pipe seat 32, and then put the rotating gear disk unit 31 to be loaded into the bottom end of the straight pipe 321, to make the stud bolt 313 pass through the axial pipe 314 of the rotating gear disk unit 31, protection cover 312, straight pipe 321 and pressing post 33. Then turns the stud bolt 313 protruding out of the pressing post 33 and the nut 335 tightly, thus completing the combination of the hole line forming structure 3.

By puting the pressing post 33 and the top end of the pipe seat 32 into the lower end of the tube 1. Then turns the stud bolt 313, and the stud bolt 313 again drives the pressing post 33 to move downward. Then the top face 321a of the pipe seat 32 and the pressing post 33 are distorted. The pipe face of the pressing post 3 then presses the inner wall of the tube 1 so that the hole line forming structure 3 is secured at the lower end of the tube body 1 to complete the combination of this invention.

When the carton size modifier of the present invention is in use as shown in FIG. 4, the position of the supporting clamp 2 on the tube is adjusted firstly to make the hooking plate 25 of the supporting clamp 2 stop on the upper edge of the carton 4. Hold the handle 322 to let the gear disk 311 rotate on the inside wall of the carton to form a hole line 41. When the excessive paper boards are cut off with scissors, it can be very easy for the user to bend the board body of the carton 4 along the hole line 41 to form the cover board, so that, the purpose to modify the size of carton can be easily achieved.

Although the present invention has been described with a certain degree of particularity, it is understood that the present disclosure has been made by way of example and that changes in details of structure may be made without depart from the spirit thereof.
